Sample records for 48-year-old man survival

  1. Congenital hypopituitarism in a 48-year old adult. Natural course, hormonal study and MRI evidence.

    Pentimone, F; Riccioni, S; Del Corso, L

    1999-12-01

    A case of Congenital Hypopituitarism (CH) in an untreated 48 yr-old-man is reported. The hormonal studies demonstrated a panhypopituitarism and MR imaging revealed absence of pituitary stalk, small anterior pituitary remnant on the sella floor and ectopic neurohypophysis at the tuber cinereum. The pattern of hormonal responsiveness suggests that CH encompasses findings typical of primary anterior pituitary disease and those of hypothalamic dysfunction. PMID:10705718

    We describe the case of a patient with a large renal cell carcinoma (RCC) who underwent cytoreductive nephrectomy utilizing liver mobilization techniques similar to those used in transplantation. Despite recurrent metastases, our patient continues to survive eight years later with several metastasectomies and adjuvant chemotherapy. We report the case of a 48-year-old Hispanic American man who presented with a 4-month history of an enlarging right upper quadrant abdominal mass and hematuria. C...

  3. Preliminary survivability analysis of manned spacecraft following orbital debris penetration

    2009-01-01

    Meteoroid and orbital debris(M/OD) may cause severe damages or even catastrophic failures for long-term manned spacecrafts in orbit due to the hypervelocity impact(HVI) destruction.It is essential to quantitatively assess the M/OD risk of manned spacecraft.In this paper,the catastrophic failure as-sessment function is successfully integrated into the Meteoroid & Orbital Debris Assessment and Op-timization System Tools(MODAOST),which is the M/OD risk assessment system developed by China Academy of Space Technology.The survivability assessment for the US Lab by MODAOST was con-sistent with that of the Manned Spacecraft Crew Survivability computer code(MSCSurv).Meanwhile,the simulation process showed that this function was more effective than MSCSurv for the application of the standard methodology of M/OD risk assessment instead of the Monte Carlo model.This function expands the ability of MODAOST in predicting the survivability of the typical catastrophic failure modes such as crew hypoxia and the critical cracking.

    Birth order has been associated with childhood obesity. The objective of this cross-sectional study was to examine maternal feeding and child eating behaviors as underlying processes for increased weight status of only children and youngest siblings. Participants included 274 low-income 4-8 year old children and their mothers. The dyads completed a videotaped laboratory mealtime observation. Mothers completed the Caregiver's Feeding Styles Questionnaire and the Children's Eating Behavior Questionnaire. Child weight and height were measured using standardized procedures. Path analysis was used to examine associations of birth order, maternal feeding behavior, child eating behavior, and child overweight/obese status. The association between only child status and greater likelihood of overweight/obesity was fully mediated by higher maternal Verbal Discouragement to eat and lower maternal Praise (all p values youngest sibling status and greater likelihood of overweight/obesity was partially mediated by lower maternal Praise and lower child Food Fussiness (all p values < 0.05). Results provide support for our hypothesis that maternal control and support and child food acceptance are underlying pathways for the association between birth order and weight status. Future findings can help inform family-based programs by guiding family counseling and tailoring of recommendations for family mealtime interactions. PMID:26009204

  6. Pathology Image Of The Month: Recurrent Urinary Tract Infections In a 48-year-Old Female Hyperintensities in the Globus Pallidi.

    Connor, Ellen E; Vinson, Anthony; Bhalla, Ritu; McGoey, Robin R

    2016-01-01

    A 48-year-old female presented to her physician complaining of intermittent lower abdominal pain radiating to the right lower back. At the time of presentation, she was afebrile and denied any urinary symptoms such as dysuria, frequency or urgency. Physical exam was unremarkable, other than obesity, and her abdominal exam was noncontributory. Medical history, however, was notable for recurrent, Proteus mirabilis culture-proven urinary tract infections requiring antibiotic treatment for the prior three years along with hypertension, uterine fibroids post hysterectomy, diabetes and asthma. Complete blood count was within normal limits, and urine dipstick showed 1+ blood, 1+ protein and 2+ leukocytes. Full renal function labs, urine cytology, radioisotope renography and abdominopelvic CT scanning with contrast were all ordered and a laparoscopic right nephrectomy was recommended based on the results. The bisected right kidney is shown below in Figure 1. She was discharged home on post-operative day one and her follow up urology appointments indicate resolution of both her urinary tract infections and her abdominal pain. PMID:27383862

  10. Man's best friend: How humans can develop Dirofilaria immitis infections.

    Malik, Devin; Amaraneni, Akshay; Singh, Sukhpreet; Roach, Richard

    2016-01-01

    Canine heartworm, Dirofilaria immitis, is a nematode parasite that infects dogs by way of mosquito bite. Rarely, humans play accidental hosts to this parasite and are not a suitable environment for the nematode to live. As the parasite dies in the pulmonary vessels it embolizes the vessels causing infarction and eventual nodule formation in the lungs. In the right clinical context, a nodule can be considered malignant prompting invasive tissue sampling. We describe a case of a 48-year-old man who was found to have multiple asymptomatic scattered pulmonary nodules during imaging workup for an insulinoma. Fine needle biopsy of the largest nodule revealed a necrotic granuloma, lab testing and culture ruled out fungal and bacterial causes. Clinically, this picture was consistent with D. immitis infection. PMID:27077028

    Full Text Available A study was conducted to appraise the effect of different stocking densities on three male morphotypes named blue claw (BC, orange claw (OC and small male (SM at harvest in all-male culture and assess the growth performance of BC, OC and SM in each isolated culture. Trials involving three stocking densities of all-male prawn viz., 20, 30 and 40 juvenile m−2 were carried out in replicates. After 4 months of culture, BC, OC and SM were sorted from all tanks and restocked at 5 m−2 in treatments BC, OC and SM respectively for 80 days. A difference in prawn density was significant (P < 0.05 affect adversely on morphotypes. The highest survival rate combined with good yields performance was from 20 juvenile m−2 stocking density with 21% BC, 62.5% OC and 16.5% SM respectively. In isolation culture, the average specific growth rate of the SM population (1.22 was significantly higher than that of the OC (1.01 and the BC (0.43 population. The survival rate of the SM population was 100% while others were 72%. Absolute weight of prawn was significantly greater in the OC male (23.87 g than the SM (19.57 g and the BC male (6.31 g. Impacts of isolated culture on population structure were much more pronounced in the SM population than others.

  12. EFFECT OF PROBIOTICS ON GROWTH AND SURVIVAL OF POST LARVAE OF GIANT FRESHWATER PRAWN, MACROBRACHIUM ROSENBERGII (DE MAN

    Shailender M*, Krishna PV, Suresh Babu Ch

    2012-10-01

    Full Text Available The trend of using probiotics in aquaculture is increasing due to research results indicating their ability to increase production and prevent disease in farm animals. The development of suitable probiotics for bio-control in aquaculture would result in less reliance on chemicals and antibiotics and result in a better environment. The production of high quality larvae in scampi is very difficult, since the disease out breaks are the major constraints in scampi hatcheries. Controlling diseases through antibiotics has been widely criticized for their negative impacts, so alternate methods needed to be developed to produce high quality scampi larvae. Application of water probiotics, soil probiotics and reduction of salinity are the methods gaining importance in controlling pathogen in scampi larvae. The larval rearing tanks are divided into four chambers for our convenience. The probiotics treated tanks are considered as experimental and without probiotics treated are considered as control. The water probiotics namely C.P (Super Biotic and Biodream (Probiotic contains Bacillus sp. and Streptococcus sp. was added in the experimental tanks alone @ 5ppm each @ 5- 10 ppm from Zoea stage-II onwards and probiotics Zymatin @ 5ppm was added after the appearance of post larval stage in experimental tanks. In addition to probiotics 0.05 ppm of Treflan was also added both experimental and control tanks to prevent the fungal disease. Water temperature, pH, dissolved oxygen, NH3 and H2S were found better in trials with probiotics. In this experiment the survival rate of the nauplii of both control and experimental tanks were more or less same.

  14. Acute hemorrhagic leukoencephalomyelitis in a man with viral myocarditis.

    Kitulwatte, Indira D; Kim, Patrick J H; Pollanen, Michael S

    2015-09-01

    We report a case of acute hemorrhagic leukoencephalomyelitis in a man with viral myocarditis. A 48-year-old previously healthy male was found dead in his locked apartment. At autopsy he was found to be malnourished, and his lungs showed gross evidence of bilateral pneumonia with abscess formation and bullous emphysema. Multiple petechial hemorrhages were observed in the brain and mainly involved white matter in the cerebral hemispheres including the corpus callosum and internal capsule, as well as the cerebellum, brainstem, and spinal cord. Microscopy of the brain and spinal cord revealed perivenular hemorrhages, central microthrombi in venules with fibrin exudation into the subcortical white matter, and early perivenular demyelination associated with scanty mixed cellular infiltrates. Other microscopic features included widespread diffuse viral myocarditis, extensive suppurative bronchopneumonia, and chronic bronchitis. This case illustrates the death of a man with a rare fatal disease associated with two other potentially lethal diseases. The case also illustrates the importance of a holistic approach when determining the cause of death, especially when there are competing causes of death. PMID:26148811

    Highest growth of prawn was obtained with Feed B (743 kg/ha) with highest survival rate (60.88%) followed by Feed A where production and survival rate was 659 kg/ha and 53.50%, respectively. Feed A contained 30% dry ground cow viscera, 40% oil cake, 20% rice-bran and 10% heat bran. Feed conversion ratios were found to be 7.60:1 for Feed A and 6.46:1 for Feed B, which indicated that Feed B was more efficiently utilized by the prawn than Feed A. Statistical analysis revealed that the difference...

  16. Symbolism in prehistoric man.

    Facchini, F

    2000-12-01

    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. PMID:11216422

  17. Man, energy, society

    Cook, E.F.

    1976-01-01

    The use of energy is examined considering technical, social, economic, and political factors. From a geographical viewpoint, the history of energy consumption is reviewed, current energy problems are delineated, and possible solutions to the energy dilemma are discussed. The following chapters are included: Energy, Environment, and Evolution; Man and Other Engines; Renewable Energy Resources; Non-Renewable Energy Resources; the Physical Economy of Energy Use; the Conservation of Free Energy; Social Evolution and Energy; Life Styles, Government, and Energy; the Geography of Energy; the Social Economy of Energy Use; Energy and the United States; Decisions About Energy; Depletion of Geologic Resources; Ethical and Moral Aspects of Energy Use; and Alternative Energy Futures. It is concluded that man must ultimately rely on renewable energy forms, but there is no promise that these energy sources can be made available at costs low enough to ensure man's survival.

  18. Peritoneal mesothelioma in a woman who has survived for seven years: a case report

    Pourgholami Mohammad H

    2011-01-01

    Full Text Available Abstract Introduction Malignant peritoneal mesothelioma is a rare cancer with poor patient survival. Female gender has been identified as a positive prognostic factor. Recently, it has been suggested that the expression of estrogen receptor β in malignant mesothelioma leads to tumor suppression and a better prognosis. Case presentation We report the case of a 48-year-old Caucasian woman who is alive and disease-free seven years after the initial diagnosis and treatment of malignant peritoneal mesothelioma. Conclusion This patient's long survival may be attributable to a combination of factors, including minimal disease, complete cytoreductive surgery and hyperthermic intraperitoneal chemotherapy plus the estrogen receptor β positivity of the tumor.

  19. Ratios of colony mass to thermal conductance of tree and man-made nest enclosures of Apis mellifera: implications for survival, clustering, humidity regulation and Varroa destructor.

    Mitchell, Derek

    2016-05-01

    In the absence of human intervention, the honeybee (Apis mellifera L.) usually constructs its nest in a tree within a tall, narrow, thick-walled cavity high above the ground (the enclosure); however, most research and apiculture is conducted in the thin-walled, squat wooden enclosures we know as hives. This experimental research, using various hives and thermal models of trees, has found that the heat transfer rate is approximately four to seven times greater in the hives in common use, compared to a typical tree enclosure in winter configuration. This gives a ratio of colony mass to lumped enclosure thermal conductance (MCR) of less than 0.8 kgW(-1) K for wooden hives and greater than 5 kgW(-1) K for tree enclosures. This result for tree enclosures implies higher levels of humidity in the nest, increased survival of smaller colonies and lower Varroa destructor breeding success. Many honeybee behaviours previously thought to be intrinsic may only be a coping mechanism for human intervention; for example, at an MCR of above 2 kgW(-1) K, clustering in a tree enclosure may be an optional, rare, heat conservation behaviour for established colonies, rather than the compulsory, frequent, life-saving behaviour that is in the hives in common use. The implied improved survival in hives with thermal properties of tree nests may help to solve some of the problems honeybees are currently facing in apiculture. PMID:26335295

  1. Insulin-like growth factor-II is produced by, signals to and is an important survival factor for the mature podocyte in man and mouse.

    Podocytes are crucial for preventing the passage of albumin into the urine and, when lost, are associated with the development of albuminuria, renal failure and cardiovascular disease. Podocytes have limited capacity to regenerate, therefore pro-survival mechanisms are critically important. Insulin-like growth factor-II (IGF-II) is a potent survival and growth factor; however, its major function is thought to be in prenatal development, when circulating levels are high. IGF-II has only previously been reported to continue to be expressed in discrete regions of the brain into adulthood in rodents, with systemic levels being undetectable. Using conditionally immortalized human and ex vivo adult mouse cells of the glomerulus, we demonstrated the podocyte to be the major glomerular source and target of IGF-II; it signals to this cell via the IGF-I receptor via the PI3 kinase and MAPK pathways. Functionally, a reduction in IGF signalling causes podocyte cell death in vitro and glomerular disease in vivo in an aged IGF-II transgenic mouse that produces approximately 60% of IGF-II due to a lack of the P2 promoter of this gene. Collectively, this work reveals the fundamental importance of IGF-II in the mature podocyte for glomerular health across mammalian species. PMID:23299523

  2. Low pH affects survival, growth, size distribution, and carapace quality of the postlarvae and early juveniles of the freshwater prawn Macrobrachium rosenbergii de Man

    2015-06-01

    Acidification of rain water caused by air pollutants is now recognized as a serious threat to aquatic ecosystems. We examined the effects of low pH (control pH 7.5, pH 6, pH 5, pH 4) on the survival, growth, and shell quality of Macrobrachium rosenbergii postlarvae and early juveniles in the laboratory. Hatcheryproduced postlarvae (PL 5) were stocked at 250 PL per aquarium, acclimated over 7 d to experimental pH adjusted with hydrochloric acid, and reared for 30 d. Dead specimens were removed and counted twice a day. After 27 d rearing, all specimens were measured for total length and body weight. Carapace quality was assessed by spectrophotometry. Survival of juveniles was highest at pH 6 (binomial 95% confidence interval 79 - 89%) followed by control pH 7.5 (56 - 68%) and pH 5 (50 - 60%) and was lowest for unmetamorphosed postlarvae and juveniles at pH 4 (43 - 49%). The final median total length and body weight of juveniles were similar at control pH 7.5 (18.2 TL, 50.2 mg BW) and pH 6 (17.7 mm TL, 45.0 mg BW) but significantly less at pH 5 (16.7 mm TL, 38.2 mg BW); at pH 4, the postlarvae did not metamorphose and measured only 9.8 mm TL, 29.3 mg BW. Length frequency distribution showed homogeneous growth at pH 6, positive skew at control pH 7.5 and pH 5, and extreme heterogeneity at pH 4. The carapace showed different transmittance spectra and lower total transmittance (i.e. thicker carapace) in juveniles at pH 7.5, pH 6, and pH 5 than in unmetamorphosed postlarvae and juveniles with thinner carapace at pH 4. Thus, survival, growth, size distribution, and carapace quality of M. rosenbergii postlarvae and early juveniles were negatively affected by pH 5 and especially pH 4. The thinner carapace of the survivors at pH 4 was mostly due to their small size and failure to metamorphose. Natural waters affected by acid rain could decimate M. rosenbergii populations in the wild.

  3. Remeasuring man.

    Weisberg, Michael

    2014-05-01

    Samuel George Morton (1799-1851) was the most highly regarded American scientist of the early and middle 19th century. Thanks largely to Stephen Jay Gould's book The Mismeasure of Man, Morton's cranial capacity measurements of different races is now held up as a prime example of and cautionary tale against scientific racism. A team of anthropologists recently reevaluated Morton's work and argued that it was Gould, not Morton, who was biased in his analysis. This article is a reexamination of the Morton and Gould controversy. It argues that most of Gould's arguments against Morton are sound. Although Gould made some errors and overstated his case in a number of places, he provided prima facia evidence, as yet unrefuted, that Morton did indeed mismeasure his skulls in ways that conformed to 19th century racial biases. Gould's critique of Morton ought to remain as an illustration of implicit bias in science. PMID:24761929

    This study investigates the neuronal correlates of empathic processing in children aged 4 to 8 years, an age range discussed to be crucial for the development of empathy. Empathy, defined as the ability to understand and share another person’s inner life, consists of two components: affective (emotion-sharing) and cognitive empathy (Theory of Mind). We examined the hemodynamic responses of pre-school and school children (N=48), while they processed verbal (auditory) and non-ver...

Empathy, defined as the ability to understand and share another person’sinner life, consists of two components: affective (emotion-sharing and cognitiveempathy (Theory of Mind. We examined the hemodynamic responses of pre-schooland school children (N=48, while they processed verbal (auditory and non-verbal(cartoons empathy stories in a passive following paradigm, using functional NearInfrared Spectroscopy (fNIRS. To control for the two types of empathy, childrenwere presented blocks of stories eliciting either affective or cognitive empathy, orneutral scenes which relied on the understanding of physical causalities.By contrasting the activations of the younger and older children, we expected toobserve developmental changes in brain activations when children process storieseliciting empathy in either stimulus modality towards a greater involvement ofanterior frontal brain regions. Our results indicate that children's processing of storieseliciting affective and cognitive empathy is associated with medial and bilateralorbitofrontal cortex (OFC activation. In contrast to what is known from studies usingadult participants, no additional recruitment of posterior brain regions was observed,often associated with the processing of stories eliciting empathy. Developmentalchanges were found only for stories eliciting affective empathy with increasedactivation, in older children, in medial OFC, left inferior frontal gyrus (IFG, and theleft dorsolateral prefrontal cortex (dlPFC. Activations for the two modalities differonly little, with non-verbal presentation of the stimuli having a greater impact onempathy processing in children, showing more similarities to adult processing thanthe verbal one. This might be caused by the fact that non-verbal processing developsearlier in life

  6. Human capabilities in space. [man machine interaction

    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.

  18. Motivational interviewing for screening and feedback and encouraging lifestyle changes to reduce relative weight in 4-8 year old children: design of the MInT study

    Taylor Barry J

    2010-05-01

    Full Text Available Abstract Background Because parental recognition of overweight in young children is poor, we need to determine how best to inform parents that their child is overweight in a way that enhances their acceptance and supports motivation for positive change. This study will assess 1 whether weight feedback delivered using motivational interviewing increases parental acceptance of their child's weight status and enhances motivation for behaviour change, and 2 whether a family-based individualised lifestyle intervention, delivered primarily by a MInT mentor with limited support from "expert" consultants in psychology, nutrition and physical activity, can improve weight outcomes after 12 and 24 months in young overweight children, compared with usual care. Methods/Design 1500 children aged 4-8 years will be screened for overweight (height, weight, waist, blood pressure, body composition. Parents will complete questionnaires on feeding practices, physical activity, diet, parenting, motivation for healthy lifestyles, and demographics. Parents of children classified as overweight (BMI ≥ CDC 85th will receive feedback about the results using Motivational interviewing or Usual care. Parental responses to feedback will be assessed two weeks later and participants will be invited into the intervention. Additional baseline measurements (accelerometry, diet, quality of life, child behaviour will be collected and families will be randomised to Tailored package or Usual care. Parents in the Usual care condition will meet once with an advisor who will offer general advice regarding healthy eating and activity. Parents in the Tailored package condition will attend a single session with an "expert team" (MInT mentor, dietitian, physical activity advisor, clinical psychologist to identify current challenges for the family, develop tailored goals for change, and plan behavioural strategies that best suit each family. The mentor will continue to provide support to the family via telephone and in-person consultations, decreasing in frequency over the two-year intervention. Outcome measures will be obtained at baseline, 12 and 24 months. Discussion This trial offers a unique opportunity to identify effective ways of providing feedback to parents about their child's weight status and to assess the efficacy of a supportive, individualised early intervention to improve weight outcomes in young children.

    Cristy, M.

    1994-10-01

    The 70-kg Standard Man or Reference Man has been used in physiological models since at least the 1920s to represent adult males. It came into use in radiation protection in the late 1940s and was developed extensively during the 1950s and used by the International Commission on Radiological Protection (ICRP) in its Publication 2 in 1959. The current Reference Man for Purposes of Radiation Protection is a monumental book published in 1975 by the ICRP as ICRP Publication 23. It has a wealth of information useful for radiation dosimetry, including anatomical and physiological data, gross and elemental composition of the body and organs and tissues of the body. The anatomical data includes specified reference values for an adult male and an adult female. Other reference values are primarily for the adult male. The anatomical data include much data on fetuses and children, although reference values are not established. There is an ICRP task group currently working on revising selected parts of the Reference Man document.

    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.)

  5. Typhoon Man-Yi

    2007-01-01

    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.

  6. Man-machine supervision

    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.

  8. Play the Man!

    Edelberg, Peter

    This book investigates ideas of men and masculinities in interwar Britain in three different areas: psychology, physical education and sex. Using a broad range of sources from different walks of life it explores how men and masculinities were constructed in different ways for different purposes...... opposites towards a heterosexual matrimonial ideal wherein men could try to establish a masculine identity. This tendency created new frontiers where homosexuals, 'perverts', 'misfits' and 'freaks' were seen as opposites of the 'real man' in the symbolic world of the early twentieth century....

    The radiation preservation of food has been receiving attention in South Africa since 1961 when a radioactive cobalt-60 unit was installed in Stellenbosch. In this unit, as in all similar units throughout the world, special attention was given to measures ensuring the safety of workers at the unit as well as that of the public. Man himself, the food he eats and the air he breathes are naturally radioactive and life on earth is impossible without nuclear reactions in the sun. These facts are elucidated so that the irradiation of food can be seen in true perspective

  14. Pathways to man

    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

  16. Light in man's environment.

    Marshall, J

    2016-02-01

    Light in the form of solar radiation influenced early civilisations and resulted in the independent development of a number of sun-worshipping dieties. These were of particular importance as hunter gatherers transformed into settled agricultural societies. All artificial light sources were synonymous with fire, and early civilisations began to expand their visual day by burning brands, oil, and candles. Fire-based light sources extended for thousands of years and were still present in the era of gas lighting. Light meant fire risk. The advent of incandescent bulbs and the era of electric lighting really only expanded in the early part of the twentieth century. Fluorescent lighting became available in the 1940s, and today the drive for low energy has resulted in a plethora of novel light sources-in particular, light-emitting diodes (LEDs). Evolution governed the development of the eye in relation to roughly 12 h of light gradually changing to 12 h of darkness. Today almost daylight levels can be achieved abruptly at the flick of a switch. Many studies have demonstrated the spectral dependence of eye health, with the retinal hazard zone associated with wavelengths in the blue, peaking at 441 nm- many of today's low-energy sources peak in this region. Given the increased longevity and artificial light sources emitting at biologically unfriendly wavelengths, attention has to be directed towards light in man's environment as a risk factor in age-related ocular diseases.

  19. Manned Mars mission cost estimate

    Hamaker, Joseph; Smith, Keith

    1986-01-01

    The potential costs of several options of a manned Mars mission are examined. A cost estimating methodology based primarily on existing Marshall Space Flight Center (MSFC) parametric cost models is summarized. These models include the MSFC Space Station Cost Model and the MSFC Launch Vehicle Cost Model as well as other modes and techniques. The ground rules and assumptions of the cost estimating methodology are discussed and cost estimates presented for six potential mission options which were studied. The estimated manned Mars mission costs are compared to the cost of the somewhat analogous Apollo Program cost after normalizing the Apollo cost to the environment and ground rules of the manned Mars missions. It is concluded that a manned Mars mission, as currently defined, could be accomplished for under $30 billion in 1985 dollars excluding launch vehicle development and mission operations.

    Puchwein, P; Prenner, G; Fell, B; Sereinigg, M; Gumpert, R

    2014-09-01

    We report the case of a 17-year-old man who sustained multiple stab wounds after a knife attack. After arrival of the emergency medical team the patient suffered a cardiac arrest caused by cardiac tamponade. After emergency thoracotomy and open heart massage the patient developed ROSC and could be discharged 13 days later without neurological deficits. Prehospital thoracotomy is rarely performed in Austria but is the only realistic chance for survival in cases of hematopericardium and tamponade. Better training of emergency physicians in Austria concerning surgical resuscitation could increase survival rates especially after penetrating thoracic trauma. PMID:23884562

    Non-patterned photic stimulation of the eyes of human subjects was obtained by homogeneous illumination of the closed eyes. The subjects perceived a difference between the stimulation intensity of the left and of the right eye as a field of view consisting of a bright and a dark half, adjoined across an indeterminate vertical midline. It is not clear which parts of the visual system mediate the residual perceptual functions that survive this stimulatory reduction of man's eyes to a photic bis...

  4. A modular approach for assessing the effect of radiation environments on man in operational systems. The radiobiological vulnerability of man during task performance

    Ewing, D. E.

    1972-01-01

    A modular approach for assessing the affects of radiation environments on man in operational systems has been developed. The feasibility of the model has been proved and the practicality has been assessed. It has been applied to one operational system to date and information obtained has been submitted to systems analysts and mission planners for the assessment of man's vulnerability and impact on systems survivability. In addition, the model has been developed so that the radiobiological data can be input to a sophisticated man-machine interface model to properly relate the radiobiological stress with other mission stresses including the effects of a degraded system.

    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 analog...

Unfortunately,in many parts of the world, man has not realized that the third one is the most important. Two thousand years ago a rich and pow-erful country cut down its trees to build war-ships, with which to gain itself an empire. It gained the empire,however,without its trees, its soil became hard and poor. When the em-pire fell to pieces, the home c...

  8. Ensuring survival.

    Sadik, N

    1992-12-01

    The global population growth rate has been 1.7% since 1975, while for developing countries it is 2.1%. UN projections are for population to grow from 5.5 billion in 1992 to 10 billion by 2050. Sustainable development is only possible when population growth is balanced with available resources. UN medium population projections of 7.8 billion by 2050 can be reached with 187 million more couples practicing family planning (FP) by the year 2000. Within the past 20 years, 1 billion people, mostly from developed countries, have enjoyed economic growth, but have contributed polluting technologies, excessive waste, and environmentally dangerous economic practices. The generations to come will be affected by the continuance of these practices by the 1 billion affluent population. The bottom billion are mired in poverty and high population growth and survival, needs that hinder their country's economic development, upset fragile ecosystems, and destroy the balance between human beings and the environment. International migration on a large scale could be the by-product of population growth. Progress has been made since the 1974 UN Conference on Population in Bucharest. There are still, however, vulnerable populations, the poorest households, the landless and small-holder families, urban squatters and slum dwellers, those living in low lying deltas and along coasts, and women. Women control family resources and their micro environment. Sustainable development is not possible without the elimination of prejudice against women. Reproductive freedom for women must be a priority. High quality, readily available FP services are also needed for those desiring this. The difficulty is in providing FP services that conform to a woman's social and cultural background and personal needs; success is dependent on involving women in the process and holding men more responsible for FP. Development means allowing for the legitimate aspirations of the majority not just the specialized

    The insects discussed in this document are those which have a direct effect upon humans either through a permanent association, as with lice, or a temporary association in the case of flies, bees, wasps, and spiders. In each case, life cycles and identifying characteristics are presented with remarks about the specific effect incurred by man. (CS)

  13. Manning of nuclear merchant ships

    The manning of nuclear propelled merchant ships bases on two principles: safe management of the vessel from the starting port to the place of destination, including cargo handling; qualification for operating a nuclear plant. The German Atomic Law requires the proof of sufficient qualifications of the personnel running land-based power stations. These requirements are applied analogously at the technical crews of nuclear powered ships. After dealing with the differences of plant operation on board ship and land-based plants the education of technical crews will be discussed. At the example of NS OTTO HAHN, the manning, education of the key positions, and responsibility of the ship's management are presented. For reasons of comparison the crews of NS SAVANNAH and NS MUTSU are opposed to this. A hint will be given on the new developments in the manning field of conventional ships, and at least a view into the future will be given under the aspect of progressive studies on the questions of manning future ships, and the work carried out by IMCO for a code of nuclear powered merchant ships

  18. Man's Impact on Groundwater Systems

    Water is an essential component of ecosystems and man's health. As the world population is growing, the need for more food, man's shift to urban areas and the progressive industrialisation all affect water resources in a qualitative and quantitative way. Connected to these general developments the following problems arise: - water exploitation increasingly concentrates on local areas with high water demands at low cost; - urbanisation contributes to the disequilibration of groundwater recharge, either by sealing the surface against infiltration or by leakage processes from the underground water transport system; - the groundwater quality is affected by leakage and accidental spills of liquid and solid wastes gathered in a few places, generally untreated or unconditionedly released, thus presenting serious dangers of pollution; - the excessive use of agrochemicals influences the natural functioning of both the soil and the aquifer, thus hampering the self-attenuation processes; - emissions from fuel and waste combustion are concentrated in few places, in the vicinity of the emission source provoking strong and quasi immediate contamination, also in the more distant surroundings slowly increasing impacts on water resources and ecosystems by dry or wet deposition; - the expansion of man's activities in arid and semi-arid regions often lead to the deterioration of resources, either by overexploitation or by desertification; - deforestation disturbs the water balance and water quality, and enhances erosion. Since water resources react on changes of land and water use with a long delay time, man's activities should be better adapted to basic hydrodynamic conditions in order to better satisfy the needs of a safe drinking water supply, flood protection, and the food and industrial production. Such basic hydrodynamic conditions comprise e.g. resource replenishment, steady state or transient dynamics and chemical stratification, which all may contribute to develop

  20. JFK's 'Landing a man on the moon' speech

    1983-01-01

    Excerpt from John F. Kennedy's special message to Congress on May 25, 1961. 'First, I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the moon and returning him safely to the earth. No single space project in this period will be more impressive to mankind, or more important for the long-range exploration of space; and none will be so difficult or expensive to accomplish. We propose to accelerate the development of the appropriate lunar space craft. We propose to develop alternate liquid and solid fuel boosters, much larger than any now being developed, until certain which is superior. We propose additional funds for other engine development and for unmanned explorations - explorations which are particularly important for one purpose which this nation will never overlook: the survival of the man who first makes this daring flight. But in a very real sense, it will not be one man going to the moon - if we make this judgment affirmatively, it will be an entire nation. For all of us must work to put him there.'

  1. Tesla man out of time

    Cheney, Margaret

    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 ...

  2. Trace element speciation in man

    The toxicological properties associated with an element depend upon its chemical form since this will dictate the metabolic pathway that the compound follows in the body. The speciation of the element is determinant for its physiological behaviour in a living system. The complicated interactions of the different forms of trace elements in human metabolism were reviewed and the species present were categorised into seven groups. The complexity of the tasks involved in a study of trace element speciation in man was illustrated and many of the pitfalls were identified together with an example of the detective approach that must be followed to elucidate the intricacies of the associations between trace elements and biomolecular moieties

  3. Deformation of Man Made Objects

    Ibrahim, Mohamed

    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.

  4. Biosafety in manned space flight

    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

    Full Text Available Anthroposophistic orientated view of R.Shtayner to development of a man during all life is systematized. Anthroposophistic conception of development of a man is based on such substantive provisions: unity corporal-heartfelt-spiritual life; connection of component parts of psyche with physiological organization of man; an interconditionality of physiological, heartfelt and spiritual development is in the rhythm of seven years. It is rotined that a health, heartfelt rest and happiness, is the result of harmonic development. All three aspects are the legal certificates of constituents life of man.

  6. The man and the universe

    Kolodziejska, Magdalena

    2016-04-01

    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

    This paper reports that an opportunity exists to achieve a substantially simpler and more reliable Man Machine Interface design than exists in current Light Water Reactor plants. This simplicity should focus on attaining a recognizable improvement in the ease of operation and a reduction of the potential for human errors. Adopting a term from computer technology, the Man Machine Interface should be User Friendly

  9. Marihuana in Man: Three Years Later

    Hollister, Leo E.

    1971-01-01

    Reviews three years of research on the effects of marihuana in man. Previously known clinical mental and physical effects have been confirmed. Causes and mechanisms of these effects generally remain undetermined in man and animals. Social implications and long term effects require additional study, although usage appears detrimental. (JM)

  10. Alternative Frameworks for the Study of Man.

    Markova, Ivana

    1979-01-01

    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)

  11. Lion and Man -- Can Both Win?

    Bollobás, B; Walters, M

    2009-01-01

    This paper is concerned with continuous-time pursuit and evasion games. Typically, we have a lion and a man in a metric space: they have the same speed, and the lion wishes to catch the man while the man tries to evade capture. We are interested in questions of the following form: is it the case that exactly one of the man and the lion has a winning strategy? As we shall see, in a compact metric space at least one of the players has a winning strategy. We show that, perhaps surprisingly, there are examples in which both players have winning strategies. We also construct a metric space in which, for the game with two lions versus one man, neither player has a winning strategy. We prove various other (positive and negative) related results, and pose some open problems.

  12. Cosmic evolution, life and man

    Among the most basic problems confronting science are those regarding the origin of the universe, the origin of life and the origin of man. This general overview starts (1) with a brief introduction addressed primarily to the Cyril Ponnamperuma Memorial. Then, the thesis is presented that the appearance of life and intelligence on our planet can be understood as the result of a number of cosmic and biological evolutionary processes, including (2) the stellar thermonuclear synthesis of the biogenic elements other than hydrogen (C, N, O, P and S), their dispersal into space, and their combination into circumstellar and interstellar molecules. (3) The formation of the Solar System and the Earth-Moon System. (4) The role of comets and carbonaceous chondrites in contributing organic matter to the primitive Earth. (5) The prebiotics synthesis of amino acids, purines, pyrimidines, fatty acids, and other biochemical monomers. (6) The prebiotic condensation reactions leading to the synthesis of oligomers such as oligonucleotides and oligopeptides, with replicative and catalytic activities. (7) The synthesis of amphiphilic lipids, and their self-assembly into liposomes with bi-layered membranes. (8) The formation of protocellular structures. (9) The activation of protocells into a functioning Darwin's ancestral cell. (10) Early evolution of life. (11) The K-T boundary event and the disappearance of dinosaurs. (12) Evolution of hominids leading to Homo sapiens. (13) The rapid development of civilization. (14) The exploration of the Solar System. (15) Life beyond our planetary system. (16) Epilogue. Peace from cosmic evolution? (Abstract only)

  13. Multinationals and plant survival

    Bandick, Roger

    2010-01-01

    The aim of this paper is twofold: first, to investigate how different ownership structures affect plant survival, and second, to analyze how the presence of foreign multinational enterprises (MNEs) affects domestic plants’ survival. Using a unique and detailed data set on the Swedish manufacturing...... sector, I am able to separate plants into those owned by foreign MNEs, domestic MNEs, exporting non-MNEs, and purely domestic firms. In line with previous findings, the result, when conditioned on other factors affecting survival, shows that foreign MNE plants have lower survival rates than non......-MNE plants. However, separating the non-MNEs into exporters and non-exporters, the result shows that foreign MNE plants have higher survival rates than non-exporting non-MNEs, while the survival rates of foreign MNE plants and exporting non-MNE plants do not seem to differ. Moreover, the simple non...

    The electronic health record (EHR) provides an unprecedented opportunity to build actionable tools to support physicians at the point of care. In this paper, we investigate survival analysis in the context of EHR data. We introduce deep survival analysis, a hierarchical generative approach to survival analysis. It departs from previous approaches in two primary ways: (1) all observations, including covariates, are modeled jointly conditioned on a rich latent structure; and (2) the observation...

  15. Transformation survival models

    Yulia Marchenko

    2014-01-01

    The Cox proportional hazards model is one of the most popular methods for analyzing survival or failure-time data. The key assumption underlying the Cox model is that of proportional hazards. This assumption may often be violated in practice. Transformation survival models extend the Cox regression methodology to allow for nonproportional hazards. They represent the class of semiparametric linear transformation models, which relates an unknown transformation of the survival time linearly to c...

  18. Man-made gemstones; Jinko hoseki

    Isogami, M. [Kyocera Corp., Kyoto (Japan)

    2000-01-01

    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)

  19. Beautiful Surfaces. Style and Substance in Florentius Schuyl's Illustrations for Descartes' Treatise on Man.

    Chan, Eleanor

    2016-01-01

    The assumption that the Cartesian bête-machine is the invention of René Descartes (1596-1650) is rarely contested. Close examination of Descartes' texts proves that this is a concept founded not on the basis of his own writings, but a subsequent critical interpretation, which developed and began to dominate his work after his death. Descartes' Treatise on Man, published posthumously in two rival editions, Florentius Schuyl's Latin translation De Homine (1662), and Claude Clerselier's Traité de l'homme, has proved particularly problematic. The surviving manuscript copies of the Treatise on Man left no illustrations, leaving both editors the daunting task of producing a set of images to accompany and clarify the fragmented text. In this intriguing case, the images can be seen to have spoken louder than the text which they illustrated. This paper assesses Schuyl's choice to represent Descartes' Man in a highly stylized manner, without superimposing Clerselier's intentions onto De Homine. PMID:27356337

  1. Man-made climate change: an overview

    Holopainen, E. [Helsinki Univ. (Finland). Dept. of Meteorology

    1995-12-31

    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

    2006-01-01

    A survival model is derived from the exponential function using the concept of fractional differentiation. The hazard function of the proposed model generates various shapes of curves including increasing, increasing-constant-increasing, increasing-decreasing-increasing, and so-called bathtub hazard curve. The model also contains a parameter that is the maximum of the survival time.

    The illicit dealing in gemstones (including diamonds) is a fast growing activity in African countries which produce these minerals. Zaire and Angola are two extreme examples, but by no means exceptions. The preferred policy efforts to controlling the flow of illicit trade in gems have been legislative actions - the police man. However, the police man has invariably failed to do the intended job. As an alternative this analysis argues for an economic approach - the economic man. It suggests ho...

    We investigated the incidences of human casualties and cattle-lifting by tigers and circumstances of attacks and suggested mitigation strategies. In India, tigers mostly survive in small numbers in protected areas which are isolated due to habitat fragmentation and disturbances. Man-killing behaviour and predation on cattle are the main issues of confrontation, and as a result, the conservation efforts are adversely affected.

  9. Comparative study of the work load between one-man buses and two-man buses.

    Ueno,Mitsuo

    1985-06-01

    Full Text Available The differences in physiological and safety conditions of one-man buses and two-man buses were examined from the view point of occupational fatigue. This survey consisted of a work load study which included a time study, study of subsidiary behavior, auditory task, memory test, Galvanic Skin Response (GSR and physiological function tests and a self-administered questionnaire which involved items concerning safety and subjective fatigue complaints. The visual and postural restrictions in the one-man bus were greater than in the two-man bus. The mental capacity of the one-man bus drivers was found to be less. Greater mental fatigue and stress were observed in the one-man bus. More subjective fatigue complaints were observed in the one-man bus. More cases of near accidents were observed in the one-man bus. From these results it was concluded that the one-man bus caused bus drivers a greater mental and physical work load.

  11. Survival of falling robots

    Cameron, Jonathan M.; Arkin, Ronald C.

    1992-01-01

    As mobile robots are used in more uncertain and dangerous environments, it will become important to design them so that they can survive falls. In this paper, we examine a number of mechanisms and strategies that animals use to withstand these potentially catastrophic events and extend them to the design of robots. A brief survey of several aspects of how common cats survive falls provides an understanding of the issues involved in preventing traumatic injury during a falling event. After outlining situations in which robots might fall, a number of factors affecting their survival are described. From this background, several robot design guidelines are derived. These include recommendations for the physical structure of the robot as well as requirements for the robot control architecture. A control architecture is proposed based on reactive control techniques and action-oriented perception that is geared to support this form of survival behavior.

    2007-01-01

    Abstract A new two-parameter probability distribution called hypertabastic is introduced to model the survival or time-to-event data. A simulation study was carried out to evaluate the performance of the hypertabastic distribution in comparison with popular distributions. We then demonstrate the application of the hypertabastic survival model by applying it to data from two motivating studies. The first one demonstrates the proportional hazards version of the model by applying it to a data se...

  14. Phenomenological Theory of Survival

    Azbel', Mark Ya.

    2001-01-01

    Theoretical analysis proves that human survivability is dominated by an unusual physical, rather than biological, mechanism, which yields an exact law. The law agrees with all experimental data, but, contrary to existing theories, it is the same for an entire species, i.e., it is independent of the population, its phenotypes, environment and history. The law implies that the survivability changes with environment via phase transitions, which are simultaneous for all generations. They allow fo...

  15. The Dog, the Horse and the Creation of Man

    Yuri Berezkin

    2014-04-01

    Full Text Available A story that described the creation of man became known to at least some inhabitants of the Eurasian Steppe zone not later than the early II millennia B.C. Not a fragment of it survived across most of this area, and our reconstruction is based on the evidence from the areas to the north and to the south of the Steppe Belt. The texts in question share many specific details and the probability of their independent emergence looks negligible. At the same time the people to whom the story was familiar in the 19th and 20th century could definitely not have borrowed it from each other in recent times. The only way to reconstruct the mythology of the people who lived in the past is a search of its survivals in the later folklore. The analysis of ancient iconography or scraps of evidence preserved in the early written sources is not enough for the reconstruction of the plots of complex tales.

  16. 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.

  17. Man and technology in the future

    The Royal Swedish Academy of Engineering Sciences has set up a committee known as The Committee of Man, Technology and Society. The members of this committee form an interdisciplinary group for the study of the interaction between scientific and technological advances and the way in which society evolves. Most of the committees activities have focused on the present relationship between man, technology and society. Attempts have been made to assess the future influence on society of key developments in biotechnology, electronic communication and systems analysis. In order to pursue this path still further, the committee decided to arrange an international symposium on the topic Man and Technology in the Future at the village of Forsmark on the Baltic coast of Sweden. The proceedings consists of 13 lectures centered on energy systems - and the connected waste problems, biotechnology, and telecommunications. Separate abstracts were prepared for 5 of the lectures in this volume

  18. Radiation protection for manned space activities

    Jordan, T. M.

    1983-01-01

    The Earth's natural radiation environment poses a hazard to manned space activities directly through biological effects and indirectly through effects on materials and electronics. The following standard practices are indicated that address: (1) environment models for all radiation species including uncertainties and temporal variations; (2) upper bound and nominal quality factors for biological radiation effects that include dose, dose rate, critical organ, and linear energy transfer variations; (3) particle transport and shielding methodology including system and man modeling and uncertainty analysis; (4) mission planning that includes active dosimetry, minimizes exposure during extravehicular activities, subjects every mission to a radiation review, and specifies operational procedures for forecasting, recognizing, and dealing with large solar flaes.

  7. The sacramental nature of man and creation

    Mihai Sebastian STOIAN

    2016-06-01

    Full Text Available God made Himself a man for man to reach the likeness of God – this is the essential idea of the oikonomia of our salvation, dear to all the Church Fathers, from Saint Irenaeus to Saint Athanasius the Great and the essence of Christ, mystery and original and fundamental sacrament of our meeting with God and of our salvation, of all of us, in Christ, and of the acquisition by each man of the fruits of salvation and deification through Christ, in the Holy Spirit, in His Church. Christ’s mystery and sacrament begins by the Embodiment of the Father’s Logos. The Passions, the cross, the tomb and the resurrection are its continuation. And all these translate the mystery of the reason why God created everything and the very mystery of man - participating to the original mystery, namely Christ, and the Church, as sacrament. Therefore, Christ is the Mystery and the sacrament by excellence - original and general -, spring and content of all the mysteries and sacraments, condition and explanation of all these.

    Hanging is known not only as a common method of suicide but also as a capital punishment method in some countries. Although several cases have been reported to survive after the attempted suicidal/accidental hanging, to the extent of our knowledge, no modern case of survival after judicial hanging exists. We reported a case of an individual who revived after modern judicial hanging despite being declared dead. The case was admitted with poor clinical presentations and the Glasgow Coma Scale of 6/15. The victim received all the standard supportive intensive care and gained complete clinical recovery. PMID:25747958

  2. Pesticides: chemicals for survival

    Pesticides are chemicals used to control pests such as insects, weeds, plant diseases, nematodes, and rodents. The increased use of pesticides since 1945 has greatly aided the increase in crop production, protected livestock from diseases such as trypanosomiasis, protected man from diseases such as malaria and filarisis, decreased losses of stored grain, and has generally improved man's welfare. Despite the enormous benefits derived from pesticides these chemicals are not problem-free. Many pesticides are toxic to living organisms and interfere with specific biochemical systems. To measure the very small quantities of a pesticide radiolabelled chemicals are frequently essential, particularly to measure changes in the chemical structure of the pesticide, movement of the pesticide in soil, plants, or animals, amounts of pesticide going through various steps in food processing, etc. The use of radiolabelled pesticides is shortly shown for metabolism of the pesticide in crop species, metabolism in ruminant, in chickens and eggs, in soil, and possibly leaching and sorption in soil, hydrolysis, bio-concentration, microbial and photodegradation, and toxicity studies

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

    Zaharijević Adriana

    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.

    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

    Anderson, Ross; Bond, Mike

    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.

  2. Man-machine interface for the MFTF

    Speckert, G.C.

    1979-11-09

    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.

    The natural world, of which we are a significant part, has many examples of survival with minimum use of energy. These examples range from the production and use of materials to the organization of entire populations. But not all organisms exist in a half-lit, miserly half-life. Their (that is to say, our driving purpose in life is to reproduce, and no organism (that is, me or you would be here unless our parents had a strong urge to reproduce, something which we, mostly, inherit. So any way that we can have the largest number of surviving offspring will be favored. In doing this we are in competition with nearly all the other organisms in the vicinity. The ones with which we are overtly friendly are our immediate genetic (or to a lesser extent, social relatives, and much has been made of the concept that it is our genes, rather than ourselves, that crave dominance.

  7. TaxMan: a taxonomic database manager

    Blaxter Mark

    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

  10. Applied survival analysis using R

    Moore, Dirk F

    2016-01-01

    Applied Survival Analysis Using R covers the main principles of survival analysis, gives examples of how it is applied, and teaches how to put those principles to use to analyze data using R as a vehicle. Survival data, where the primary outcome is time to a specific event, arise in many areas of biomedical research, including clinical trials, epidemiological studies, and studies of animals. Many survival methods are extensions of techniques used in linear regression and categorical data, while other aspects of this field are unique to survival data. This text employs numerous actual examples to illustrate survival curve estimation, comparison of survivals of different groups, proper accounting for censoring and truncation, model variable selection, and residual analysis. Because explaining survival analysis requires more advanced mathematics than many other statistical topics, this book is organized with basic concepts and most frequently used procedures covered in earlier chapters, with more advanced topics...

  11. Curcumin attenuates Mancozeb-induced toxicity in rat thymocytes through mitochondrial survival pathway.

    The widely used fungicide Mancozeb (Man) has been shown to cause genotoxic effects in rodents and toxicological manifestations in different cells, mainly by altering the antioxidant defense in cells. On the other hand, curcumin (Cur), a natural phenolic compound, is thought to possess anti-inflammatory and antioxidant properties. Here, we investigated the possible protective role of Cur on Man-induced toxicity in rat thymocytes and potential mechanism involved. Rat thymocytes were treated with Man(0.01 μg/ml) and/or increasing Cur(0.3, 1, 3 μM) concentrations and levels of cell viability, apoptosis, mitochondrial membrane potential (MMP),Bcl-2, Bax protein expression, caspase-3 and -9 activity and p38 MAPK signaling involvement were examined. Cells treated with Man displayed increased cell toxicity, hypodiploid cells, caspase-3 and -9 activity, Bax protein expression, followed with decreased MMP and Bcl-2 protein expression. Inhibition of p38 MAPK signaling pathway markedly reduced apoptosis rate and caspase-3 activity in thymocytes exposed to Man. Application of increasing Cur (1, 3 μM) concentrations resulted with significantly reduced cytotoxicity, apoptosis, caspase-3, -9 activity, Bax protein expression, together with increased MMP and Bcl-2 protein expression in rat thymocytes. These result suggest that certain Cur concentrations may mediate Man-induced rat thymocytes toxicity through mitochondrial survival pathway, which may be useful in preventing possible secondary immunological consequences induced by Man.

    An analysis of foreign literature on treatment acute leukoses with irradiation and transplantation of allogenic bone marrow is given. It is shown that whole-body irradiation used to increase treatment efficiency of man hemoblastosis are widely applied nowadays abroad. Bone marrow transplantation including compulsory whole-body irradiation with 10 Gy is the only practicable attempt to eradicate leukosis. Whole-body irradiation unlike chemotherapy provides more durable survival rate without recurrence; it doesn't require hospitalization and continuity of treatment following the general course; it doesn't produce toxic complications.

  17. Design of survivable networks

    Stoer, Mechthild

    1992-01-01

    The problem of designing a cost-efficient network that survives the failure of one or more nodes or edges of the network is critical to modern telecommunications engineering. The method developed in this book is designed to solve such problems to optimality. In particular, a cutting plane approach is described, based on polyhedral combinatorics, that is ableto solve real-world problems of this type in short computation time. These results are of interest for practitioners in the area of communication network design. The book is addressed especially to the combinatorial optimization community, but also to those who want to learn polyhedral methods. In addition, interesting new research problemsare formulated.

  19. SURVIV for survival analysis of mRNA isoform variation.

    Shen, Shihao; Wang, Yuanyuan; Wang, Chengyang; Wu, Ying Nian; Xing, Yi

    2016-01-01

    The rapid accumulation of clinical RNA-seq data sets has provided the opportunity to associate mRNA isoform variations to clinical outcomes. Here we report a statistical method SURVIV (Survival analysis of mRNA Isoform Variation), designed for identifying mRNA isoform variation associated with patient survival time. A unique feature and major strength of SURVIV is that it models the measurement uncertainty of mRNA isoform ratio in RNA-seq data. Simulation studies suggest that SURVIV outperforms the conventional Cox regression survival analysis, especially for data sets with modest sequencing depth. We applied SURVIV to TCGA RNA-seq data of invasive ductal carcinoma as well as five additional cancer types. Alternative splicing-based survival predictors consistently outperform gene expression-based survival predictors, and the integration of clinical, gene expression and alternative splicing profiles leads to the best survival prediction. We anticipate that SURVIV will have broad utilities for analysing diverse types of mRNA isoform variation in large-scale clinical RNA-seq projects. PMID:27279334

    In 1979, writer Tom DeFalco was paired with artist and cocreator of Spider-Man, Steve Ditko, to work on an issue of Machine Man, one of the many superheroes populating the universe of Marvel Comics. Instead of the usual introduction and business chatter, Ditko challenged DeFalco during a first conversation: "Are you Tom? What gives you the right to write about heroes?" (Tucker 2012). By the time of this exchange, Ditko had not only (co-) created and continued numerous superhero stories, rangi...

  2. Man machine interface based on speech recognition

    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.

  3. Design and Construction of Manned Lunar Base

    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

    Full Text Available Several diseases cause cystic or cyst-like parenchymal lung abnormalities including adult pulmonary Langerhan’s cell histiocytosis (PLCH, lymphangioleiomyomatosis (LAM, emphysema, end-stage interstitial lung disease, and cystic bronchiectasis. Many of these diseases can now be diagnosed with high accuracy by the use of high-resolution computerized tomography (HRCT. In fact, HRCT of chest has proved a major breakthrough in the diagnosis of these diseases. We are presenting a young man with a cystic lung disease in which, the HRCT findings were virtually diagnostic of that disease. The clinical and HRCT findings of this disease along with its differential diagnosis are discussed in this paper.

  5. Compartment models of radioiodine in man

    The differential equations governing the flow of iodine through a three-compartment model of iodine metabolism in man have been solved and the solutions compared to those obtained from two-compartment models. The boundary conditions used were those appropriate for a single acute exposure to radioiodine. The urinary excretion equation derived from the solutions to the three-compartment model exhibits a minimum at four days after the exposure time. This minimum can be used to calculate a maximum value for thyroid burden using a single urinary excretion rate measurement, and in conjunction with this value, an optimum urinary sampling frequency for the different radioiodines can be calculated.

  6. Gastrointestinal absorption of uranium 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 234U to 238U activity ratio and is the primary source of 234U in their diets. For two individuals, the values obtained for the fractional absorption of 234U were 0.004 and 0.006. The values obtained for the fractional absorption of 238U, using a literature value for the 238U intake from food, were 0.008 and 0.015. The present ICRP value is 0.20. 7 references, 1 table

    Delbeke, J; McComas, A J; Kopec, S J

    1978-04-01

    Surface electrodes have been used to record potentials evoked in the lumbosacral region of 15 healthy volunteers after tibial nerve stimulation. By monitoring the M waves and H reflexes in the triceps surae muslces and by comparing the responses recorded over the roots with those over the lower cord, it was possible to identify the neural substrates responsible for several of the components in the responses. The findings are compared with those of previous studies in man and in other mammalian preparations. PMID:650237

  9. Monitoring man's impact in the coastal zone

    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

According to Flusser, immaterial culture and fenomena like information result from codes. It seems to him that the codified condition of the world emerge as images onthe electronic screens, data stored in hard disk drive, cartridges film, holograms and programs which could be only decodable and which should not be apprehended. The man from the codified world does not concern about things, but about the signs interpreted by the codes.

  12. The man-machine-organisation interface

    The reliable and safety-centred action of man is one crucial factor for safe operation of nuclear power plants, apart from the technical systems and the organisational aspects. Essential factors influencing human performance are: Qualification and competence of the operating personnel, technical conditions and status of systems, including the level of automation, information technology in the control room, and plant organisation. Analyses of documentation of notifiable events in power plant operation or other incidents yield information on available potentials for safety enhancements or reduction of human errors. (orig./CB)

  13. Man-caused seismicity of Kuzbass

    Emanov, Alexandr; Emanov, Alexey; Leskova, Ekaterina; Fateyev, Alexandr

    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

  14. Nuclear war survival skills

    This book includes chapters on psychological preparations, warning and communications, and evacuation. It describes the building of expedient shelters, their ventilation and cooling, the purification and storage of adequate water, the processing and cooking of whole grains and legumes, fallout meters, protection against fires and carbon monoxide, and expedient furnishings for shelters. Other chapters cover sanitation and preventive medicine, medical advice for nuclear survivors lacking the help of doctors, improvised footwear and clothing, and advice on minimum preparations that can be made at low cost and should be made before a crisis arises. One appendix of the handbook gives detailed, field-tested instructions for building six types of earth-covered expedient fallout shelters, with criteria to guide the choice of which shelter to build. Others contain instructions for making an efficient shelter-ventilating pump and a homemade fallout meter that is accurate and dependable with inexpensive materials found in most households. This report is primarily a compilation and summary of civil defense measures and inventions developed at ORNL over the past 14 years and field-tested in six states, from Florida to Utah. It is the first comprehensive handbook of survival information for use by untrained citizens who want to improve their chances of surviving a possible nuclear attack. Sections may be easily excerpted and reproduced for mass distribution through news media

  15. Climate and man in the Arctic

    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

  17. [Genodermatosis in man and animal. Comparative overview].

    Küster, W; Happle, R

    1983-11-01

    Fourteen monogenic cutaneous disorders of man are compared to similar gene defects in animals. The traits are classified into two groups. In the first group, an identity (homology) of the underlying gene defects is likely. This group includes oculo-cutaneous albinism, Chédiak-Higashi syndrome, aplasia cutis congenita, Ehlers-Danlos syndrome (type I), hypohidrotic ectodermal dysplasia of the Christ-Siemens-Touraine type, X-linked dominant chondrodysplasia punctata, ichthyosis congenita gravis, Menkes syndrome, erythropoetic porphyria, porphyria cutanea tarda, and acrodermatitis enteropathica. In the second group, the traits are similar but the question of their homology cannot be settled. It includes alopecia congenita, hidrotic ectodermal dysplasia of the Clouston type, and hereditary lymphedema. The existence of identical mutations in man and animals provides evidence for the close relationship between the various mammalian species. Homologous traits affecting the skin are of practical importance since the use of these animal models may help to answer those questions which cannot be answered by performing research in human patients.

  18. Adaptive myelination from fish to man.

    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. This article is part of a Special Issue entitled SI: Myelin Evolution. PMID:26498877

  19. Abstraction of man-made shapes

    Mehra, Ravish

    2009-01-01

    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.

  20. Cosmological magnetic field survival

    Barrow, John D

    2011-01-01

    It is widely believed that primordial magnetic fields are dramatically diluted by the expansion of the universe. As a result, cosmological magnetic fields with residual strengths of astrophysical relevance are generally sought by going outside standard cosmology, or by extending conventional electromagnetic theory. Nevertheless, the survival of strong B-fields of primordial origin is possible in spatially open Friedmann universes without changing conventional electromagnetism. The reason is the hyperbolic geometry of these spacetimes, which slows down the adiabatic magnetic decay-rate and leads to their superadiabatic amplification on large scales. So far, the effect has been found to operate on Friedmannian backgrounds containing either radiation or a slow-rolling scalar field. We show here that the superadiabatic amplification of large-scale magnetic fields, generated by quantum fluctuations during inflation, is essentially independent of the type of matter that fills the universe and appears to be a generi...

  1. Sleep monitoring: the second manned Skylab mission.

    Frost, J D; Shumate, W H; Salamy, J G; Booher, C R

    1976-04-01

    The first objective measurements of man's ability to obtain adequate sleep during prolonged space flight were made during the three manned Skylab missions. EEG, EOG, and head-motion signals were acquired during sleep by use of an elastic recording cap containing sponge electrodes and an attached miniature preamplifier/accelerometer unit. A control-panel assembly, mounted in the sleep compartment, tested electrodes, preserved analog signals, and automatically analyzed data in real time (providing a telementered indication of sleep stage). One subject was studied during each manned mission and, while there was considerable variation among individuals, several characteristics were common to all three: stage 3 sleep increased during the flight and decreased in the postflight period; stage 4 was consistently decreased postflight, although this stage was variable during the flight; stage REM (rapid eye movement) was elevated, and REM latency decreased in the late postflight period (after day 3 postrecovery); and the number of awakenings during sleep either showed no change or decreased during the flight. In only the 28-d mission (Skylab 2) was there a significant decrease in total sleep time; in that case it was a result of voluntarily reduced rest time and was not due to difficulty in sleeping nor frequent awakening. The subject on the 84-d mission (Skylab 4) experienced more difficulty in the first half of the flight, showing a decreased total sleep time and increased sleep latency, but this resolved itself with time. Sleep latency presented no problem in the other flights. While many of the findings are statistically significant, in no case would they be expected to produce a noticeable decrement of performance capability. These findings suggest that men are able to obtain adequate sleep in regularly scheduled 8-h rest periods during extended space flights. It seems likely, based upon these results, that the problems encountered in earlier space flights did not arise

  2. Cytologic-Biochemical Radiation Dosimeters in Man

    The result of radiation interacting with living tissue is the deposition of energy therein. This energy triggers numerous chemical reactions within the molecules of the target tissues. We have measured in man the results of some of these reactions at doses up to 300 rads: chromosome aberrations; alterations in the kinetics of specific human cell populations; changes in 37 biochemical constituents of serum and/or urine. The utilization of chromosomes as a biological dosimeter is partially perfected but there are numerous discrepancies in data between different laboratories. Etiocholanolone can be used to evaluate marrow injury before the white-cell count falls below 5000/mm3. Most biochemical dosimeters evaluated gave negative or inconsistent results. However, salivary amylase is a promising indicator of human radiation injury from doses as low as 100 rads. (author)

  3. Boscovich: scientist and man of letters

    Proverbio, E.

    Ruggiero Giuseppe Boscovich (1711-1781) is known as one of the most important scientists of the second half of XVIII century, but he was active also as a man of letters, especially through an abundant production of poems in Latin verse. We try to interpret these two, apparently antinomic, aspects of his character in the framework of the culture of his epoch, in which science and literary productions were not considered as two separate or opposite fields, but only two different aspects of human knowledge. In particular we review the field of his poetic production in which this fundamental unity of knowledge is most evident, namely his poems with didactic-scientific subjects, which are examples of high-level popularization of the latest progresses in science (in particular astronomy and Newtonian physics) by means of elegant Latin verse.

  4. The methodology of man-machine systems

    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 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.

  6. Man's role in space exploration and exploitation

    Loftus, Joseph P.

    1987-01-01

    The crew workloads on the Space Shuttle are described. The Space Shuttle is designed to minimize the activity of the crew in maintaining and operating the Shuttle in order for the crew to be involved in productive activities. The changing role of the crew due to the use of more automated systems on spacecraft is examined. The Shuttle flight system is dependent on embedded software, and the crew is to manage and support these systems. The primary functions of the Space Station are as a laboratory and for construction and assembly of systems, requiring EVA. Examples of EVA are presented. The correlation between manned and unmanned systems and the future direction of space research are discussed.

  7. Space radiation concerns for manned exploration

    Stanford, Michael; Jones, Jeffrey A.

    1999-09-01

    Spaceflight exposes astronaut crews to natural ionizing radiation. To date, exposures in manned spaceflight have been well below the career limits recommended to NASA by the National Council of Radiation Protection and Measurements (NCRP). This will not be the case for long-duration exploratory class missions. Additionally, International Space Station (ISS) crews will receive higher doses than earlier flight crews. Uncertainties in our understanding of long-term bioeffects, as well as updated analyses of the Hiroshima, Nagasaki and Chernobyl tumorigenesis data, have prompted the NCRP to recommend further reductions by 30-50% for career dose limit guidelines. Intelligent spacecraft design and material selection can provide a shielding strategy capable of maintaining crew exposures within recommended guidelines. Current studies on newer radioprotectant compounds may find combinations of agents which further diminish the risk of radiation-induced bioeffects to the crew.

    Csikor, Ferenc; Hegedüs, P; Horváth, V K; Katz, S D; Piróth, A

    2001-01-01

    We briefly describe the Poor Man's Supercomputer (PMS) project that is carried out at Eotvos University, Budapest. The goal is to develop a cost effective, scalable, fast parallel computer to perform numerical calculations of physical problems that can be implemented on a lattice with nearest neighbour interactions. To reach this goal we developed the PMS architecture using PC components and designed a special, low cost communication hardware and the driver software for Linux OS. Our first implementation of the PMS includes 32 nodes (PMS1). The performance of the PMS1 was tested by Lattice Gauge Theory simulations. Using SU(3) pure gauge theory or bosonic MSSM on the PMS1 computer we obtained 3$/Mflops price-per-sustained performance ratio. The design of the special hardware and the communication driver are freely available upon request for non-profit organizations.

  9. Research with radioactive materials in man

    In connection with the revision of the Radiation Protection Ordinance, for instance in section 41, the author - who can draw on his own experience as a referee for projects planned in the area of research with radioactive materials in man - deals with the following problems: 1. Quantifiable risk-benefit assessment as opposed to qualitative risk-benefit assessment based on medical experience. 2. Delimination of medicine and research by criteria such as application to healthy or sick persons, application of a new method or an already standardized one, application in the hope to achieve an individual benefit or without such hopes, and application with a view to obtaining results suitable to be generalized, in the course of which many borderline cases will crop up. 3. Legal requirements in section 41 of the Radiation Protection Ordinance with the demands for minimization of risks and quality assurance, and 4. application procedure and experience gathered so far.

  10. Treatment of radiostrontium uptake in man

    In short-term experiments on rats the passage of radioactive strontium through the intestinal wall was modified by oral treatment using barium sulphate and normal calcium phosphate. However, in rats on a diet containing barium sulphate there was no change in the absorption of Sr90 given in drinking water. It was concluded that this substance could be of value in first-aid treatment only. In two cases of slight internal contamination following accidental Sr90 nitrate inhalation, barium sulphate (Skiabaryum Spofa) was administered orally within 10 and 30 min after the inhalation of Sr90. The effectiveness of this treatment was tested in model experiments on rats performed under similar conditions as in the accidents. More recently, experiments on similar lines have been carried out on several cancer patients, in order to investigate further possibilities of first-aid treatment following acute internal radiostrontium contamination in man.

    1993-03-01

    The Isle of Man Tourist Trophy motorcycle races remain one of the most popular venues for motorcycle races. This is despite the reduced status of the event. The reason for the loss of world championship and formula one status is the nature of the road racing circuit itself. The twisting narrow roads are only closed to the public at certain times during the practice and race weeks. Motorcycling visitors to the event attempt to emulate their heroes on machines capable of high speeds. Casualties from both visitors and racers are dealt with efficiently by an expanded medical service. This includes the use of an aeromedical evacuation helicopter. Casualties from the visitors exceeded those from the racers themselves during the period reported. PMID:8457818

  12. A young man with polyuria and lethargy

    2011-01-01

    Full Text Available 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.

    2016-03-01

    Glucagon is believed to be a pancreas-specific hormone, and hyperglucagonemia has been shown to contribute significantly to the hyperglycemic state of patients with diabetes. This hyperglucagonemia has been thought to arise from α-cell insensitivity to suppressive effects of glucose and insulin combined with reduced insulin secretion. We hypothesized that postabsorptive hyperglucagonemia represents a gut-dependent phenomenon and subjected 10 totally pancreatectomized patients and 10 healthy control subjects to a 75-g oral glucose tolerance test and a corresponding isoglycemic intravenous glucose infusion. We applied novel analytical methods of plasma glucagon (sandwich ELISA and mass spectrometry-based proteomics) and show that 29-amino acid glucagon circulates in patients without a pancreas and that glucose stimulation of the gastrointestinal tract elicits significant hyperglucagonemia in these patients. These findings emphasize the existence of extrapancreatic glucagon (perhaps originating from the gut) in man and suggest that it may play a role in diabetes secondary to total pancreatectomy.

  14. Affect, History, and Race and Ellison's Invisible Man

    Bourassa, Alan

    2006-01-01

    In his article "Affect, History, and Race and Ellison's Invisible Man" Alan Bourassa explores the implications of the Deleuze and Guattarian concept of "affect" for a reading of Ralph Ellison's Invisible Man. In the novel's most problematic relationship -- that between race and history -- there is a third term that transforms the problematic. Invisible Man is simultaneously a conventional novel that establishes emotional individuality as the third term between history and race, and an "underg...

  15. Measurement of total body radioactivity in man

    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.)

  16. Two-Man Bobsled Push Start Analysis

    Lopes Alexandre Dias

    2016-04-01

    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.

    A previously fit 48-year-old man was admitted with an acute respiratory failure due to mycoplasma pneumonia that was confirmed by raised mycoplasma titre on complement fixation test. It was also associated with disseminated intravascular coagulopathy. The patient made a full recovery but required intermittent positive pressure ventilation.

  5. Sequential MRI in a case of Creutzfeldt-Jakob disease

    A 48-year-old man suddenly developed clinically and electroencephalographically nonspecific dementia. On MRI sequences, only diffusion-weighted images (DWI) of the cortex were unequivocally pathological. Obvious atrophy and basal ganglia signal changes appeared only 9 months after the onset. Brain biopsy confirmed Creutzfeldt-Jakob disease (CJD). In rapidly progressive dementia, we recommend DWI for early diagnosis of CJD. (orig.)

  6. Survival After Relapse of Medulloblastoma.

    Koschmann, Carl; Bloom, Karina; Upadhyaya, Santhosh; Geyer, J Russell; Leary, Sarah E S

    2016-05-01

    Survival after recurrence of medulloblastoma has not been reported in an unselected cohort of patients in the contemporary era. We reviewed 55 patients diagnosed with medulloblastoma between 2000 and 2010, and treated at Seattle Children's Hospital to evaluate patterns of relapse treatment and survival. Fourteen of 47 patients (30%) over the age of 3 experienced recurrent or progressive medulloblastoma after standard therapy. The median time from diagnosis to recurrence was 18.0 months (range, 3.6 to 62.6 mo), and site of recurrence was metastatic in 86%. The median survival after relapse was 10.3 months (range, 1.3 to 80.5 mo); 3-year survival after relapse was 18%. There were trend associations between longer survival and having received additional chemotherapy (median survival 12.8 vs. 1.3 mo, P=0.16) and radiation therapy (15.4 vs. 5.9 mo, P=0.20). Isolated local relapse was significantly associated with shorter survival (1.3 vs. 12.8 mo, P=0.009). Recurrence of medulloblastoma is more likely to be metastatic than reported in previous eras. Within the limits of our small sample, our data suggest a potential survival benefit from retreatment with cytotoxic chemotherapy and radiation even in heavily pretreated patients. This report serves as a baseline against which to evaluate novel therapy combinations. PMID:26907655

  7. Operational Philosophy Concerning Manned Spacecraft Cabin Leaks

    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

  10. The risk of nuclear power plants for man

    To leave from three questions, the author intends to analyse the risk of nuclear power plants for man. He talks about biological radiation effects, sources, level and radiation effects in man. He uses the three Mile Island accident as lesson in order to illustrate a situation potentially dangerous. (C.M.)

  11. Estimation of dose to man from environmental tritium

    Factors important for characterization of tritium in environmental pathways leading to exposure of man are reviewed and quantification of those factors is discussed. Parameters characterizing the behavior of tritium in man are also subjected to review. Factors to be discussed include organic binding, bioaccumulation, quality factor and transmutation. A variety of models are presently in use to estimate dose to man from environmental releases of tritium. Results from four representative models are compared and discussed. Site-specific information is always preferable when parameterizing models to estimate dose to man. There may be significant differences in dose potential among geographic regions due to variable factors. An example of one such factor examined is absolute humidity. It is concluded that adequate methodologies exist for estimation of dose to man from environmental tritium although a number of areas are identified where additional tritium research is desirable

  12. Chemical and radiation carcinogenesis in man and experimental animals

    It is now well established that some cancer in man results from exposures to certain chemicals and radiations, both ultraviolet and ionizing radiations. These chemical and physical agents are also carcinogenic in experimental animals and, where adequately tested, in mammalian cell cultures. However, only very limited data are available on the relative roles of and the interrelationships, if any, between these various environmental agents in the causation of the majority of the cancers in man. Nothing is known of the relationship between these agents and possible carcinogenic viral information in the etiology of cancer in man. Furthermore, little is known about the molecular mechanisms by which chemicals and radiations induce cancers in either man or experimental animals. The objective of this brief review is to present certain aspects of chemical and radiation carcinogenesis in man and experimental animals and some of the problems in the elucidation of their roles in carinogenesis in the human

  13. Man-machine interaction in accident conditions

    The paper concerns the current activities in the area of enhancing the man-machine interface in accident conditions and stresses that the technique of artificial intelligence is the best way to attain significant progress in nuclear safety. The peculiarities of the WWER-440, model V-230, are discussed from the point of view of accident monitoring and management. Two expert systems - SAMES and RPES - are designated as operator aids in the event of an NPP accident with a radiation release. It is important to vary the content and the structure of the knowledge bases, depending on the user's requirements and responsibilities. Independent of the fact that both expert systems include some similar functions, for instance identification of the class of the accident, the diagnostic modules are different. This difference concerns the level of abstraction in pattern recognition and the different knowledge domains. RPES also includes different deterministic models for atmospheric transport, identification of the endangered area and estimation of the dose equivalents to the public. These allow the implementation of different protective measures to reduce the risk to the population. (author). 5 refs, 3 figs

  14. Environmental pathways of radioactivity to man

    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. Freezing water in no-man's land.

    Manka, Alexandra; Pathak, Harshad; Tanimura, Shinobu; Wölk, Judith; Strey, Reinhard; Wyslouzil, Barbara E

    2012-04-01

    We report homogeneous ice nucleation rates between 202 K and 215 K, thereby reducing the measurement gap that previously existed between 203 K and 228 K. These temperatures are significantly below the homogenous freezing limit, T(H)≈ 235 K for bulk water, and well within no-man's land. The ice nucleation rates are determined by characterizing nanodroplets with radii between 3.2 and 5.8 nm produced in a supersonic nozzle using three techniques: (1) pressure trace measurements to determine the properties of the flow as well as the temperature and velocity of the droplets, (2) small angle X-ray scattering (SAXS) to measure the size and number density of the droplets, and (3) Fourier Transform Infrared (FTIR) spectroscopy to follow the liquid to solid phase transition. Assuming that nucleation occurs throughout the droplet volume, the measured ice nucleation rates J(ice,V) are on the order of 10(23) cm(-3) s(-1), and agree well with published values near 203 K.

  16. 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.

  17. Facts, Principles and the Third Man

    Lea Ypi

    2012-02-01

    Full Text Available In the dialogue entitled “Parmenides” Plato introduces an objection to his own theory of ideas, one that he never managed to answer, dubbed by Aristotle as the “Third Man” argument. According to that objection, the theory of ideas is threatened with infinite regress when examining why a specific Platonic form (say, justice is predicated of a particular set of facts. This article seeks to show how any defence of fact-insensitive principles like the one offered by G.A. Cohen in his recent book “Rescuing Justice and Equality” is vulnerable to a similar objection. Cohen wants to insist that, when showing why facts support principles, the process of reason-giving is finite and terminates in fact-independent comprehensive principles. But something like the Third Man argument undermines Cohen’s conclusion just as it does Plato’s. The search for ultimate fact-independent principles is indeed threatened by infinite regress.

    Ehrlich, Carl F., Jr.; Potts, Jack; Brown, Jerry; Schell, Ken; Manley, Mary; Chen, Irving; Earhart, Richard; Urrutia, Chuck; Randolph, Ray; Morris, Jim

    1992-01-01

    To assure national leadership in space operations and exploration in the future, NASA must be able to provide cost effective and operationally efficient space transportation. Several NASA studies and the joint NASA/DoD Space Transportation Architecture Studies (STAS) have shown the need for a multi-vehicle space transportation system with designs driven by enhanced operations and low costs. NASA is currently studying an advanced manned launch system (AMLS) approach to transport crew and cargo to the Space Station Freedom. Several single and multiple stage systems from air-breathing to all-rocket concepts are being examined in a series of studies potential replacements for the Space Shuttle launch system in the 2000-2010 time frame. Rockwell International Corporation, under contract to the NASA Langley Research Center, has analyzed a two-stage all-rocket concept to determine whether this class of vehicles is appropriate for the AMLS function. The results of the pre-phase A study are discussed.

  19. Metabolic studies in man using stable isotopes

    In this project, stable isotope compounds and stable isotope pharmaceuticals were used (with emphasis on the application of 15N) to study several aspects of nitrogen metabolism in man. Of the many methods available, the 15N 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 15N 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

  20. Man-machine interface versus full automation

    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

  1. Landing Energy Dissipation for Manned Reentry Vehicles

    Fisher, Lloyd J., Jr.

    1960-01-01

    Analytical and experimental investigations have been made to determine the landing-energy-dissipation characteristics for several types of landing gear for manned reentry vehicles. The landing vehicles are considered in two categories: those having essentially vertical-descent paths, the parachute-supported vehicles, and those having essentially horizontal paths, the lifting vehicles. The energy-dissipation devices discussed are crushable materials such as foamed plastics and honeycomb for internal application in couch-support systems, yielding metal elements as part of the structure of capsules or as alternates for oleos in landing-gear struts, inflatable bags, braking rockets, and shaped surfaces for water impact. It appears feasible to readily evaluate landing-gear systems for internal or external application in hard-surface or water landings by using computational procedures and free-body landing techniques with dynamic models. The systems investigated have shown very interesting energy-dissipation characteristics over a considerable range of landing parameters. Acceptable gear can be developed along lines similar to those presented if stroke requirements and human-tolerance limits are considered.

  2. Coeficiente de rugosidade de Manning para o rio Paracatu Manning roughness coefficient for Paracatu river, Brazil

    Guilherme B. Lyra

    2010-04-01

    Full Text Available Pela teoria do escoamento em canais abertos, o coeficiente de rugosidade de Manning é um dos principais parâmetros para descrição da vazão sobre uma superfície. Uma das dificuldades da aplicação da equação de Manning é a definição do seu coeficiente de rugosidade em rios e canais, razão pela qual o presente estudo tem como objetivo, estimar o coeficiente de rugosidade de Manning para os períodos de vazão mínima e máxima média mensal, em alguns trechos do rio Paracatu, e propor um modelo baseado em redes neurais artificiais para estimar o coeficiente de rugosidade. O coeficiente foi determinado em função das características geométricas do canal (área molhada, raio hidráulico e declividade do canal e das séries de vazão de seis postos fluviométricos do rio Paracatu. Utilizaram-se séries de vazão de 21 anos (1976-1996. O coeficiente de rugosidade não apresenta tendência (maior ou menor em função apenas do período seco ou de cheia. As características da margem e do leito do rio influenciam diretamente nos valores de coeficiente de rugosidade. O modelo baseado em rede neural apresentou desempenho satisfatório, o que possibilita estimar o coeficiente de rugosidade em função da cota, vazão, declividade e do raio hidráulico do rio.According to open channel draining theory, the Manning's roughness coefficient is one of most important parameters to describe surface flow. One of the difficulties in applications of Manning's equation is the definition of its roughness coefficient in rivers and channels. Thus, the aims of this paper are to estimate the Manning's roughness coefficient for the periods of minimum and maximum mean monthly flow in some parts of Paracatu river and to propose a model based on artificial neural networks to estimate the roughness coefficient. The coefficient was determined in function of channel geometrical characteristics (wetted area, hydraulic radius and slope of the channel and of the

    Studies on cardiovascular disease (CVD) incidence and survival show varying results between different ethnic groups. Our aim was to add a new dimension by exploring the role of migrant status in combination with ethnic background on incidence of-and survival from-CVD and more specifically acute...... of some types of cardiovascular disease compared to Danish-born. Family-reunified migrants on the other hand had lower rates of CVD. All migrants had better survival than Danish-born indicating that migrants may not always be disadvantaged in health....

  4. Gabriel Richet: the Man and the Scientist.

    Ardaillou, Raymond; Ronco, Pierre

    2016-02-01

    Gabriel Richet who died in Paris in October 2014 was the fourth of a brilliant dynasty of professors of medicine including a Nobel prize, his grandfather, Charles Richet. He behaved courageously during the Second World War and participated in the Campaign of France in 1940 and in the combats in the Vosges Mountains in 1945. His family participated in the resistance during the German occupation of France and three of his parents including his father, one of his brothers and one of his cousins were deported in Germany. At the end of the war, he was with Jean Hamburger the founder of French nephrology at Necker Hospital in Paris. He realized the first hemodialyses in France and was involved in the first allogenic transplantation that was not immediately rejected. From 1961 to 1985, he was the head of a school of nephrology at Tenon Hospital and attracted in his department many young collaborators and scientists. He was the first to describe the role of specialized cells of the collecting duct in the control of acid base equilibrium. He was the subject of a national and international recognition. Founding member of the International Society of Nephrology in 1960, he was elected his President from 1981-1984. His fame could be measured by the number of fellows and visiting facultiesfrom countries all over the world. When he retired in 1985, he left an important legacy involving several departments of nephrology directed by his ancient collaborators. After his retirement, he was an active member of the French Academy of Medicine and devoted much of his time to the history of medicine and, particularly, of nephrology. The main qualities of the man were his constant research of new ideas, his eagerness to work and his open mind to understand others. PMID:26913875

  5. Testosterone and aggressive behavior in man.

    Batrinos, Menelaos L

    2012-01-01

    Atavistic residues of aggressive behavior prevailing in animal life, determined by testosterone, remain attenuated in man and suppressed through familial and social inhibitions. However, it still manifests itself in various intensities and forms from; thoughts, anger, verbal aggressiveness, competition, dominance behavior, to physical violence. Testosterone plays a significant role in the arousal of these behavioral manifestations in the brain centers involved in aggression and on the development of the muscular system that enables their realization. There is evidence that testosterone levels are higher in individuals with aggressive behavior, such as prisoners who have committed violent crimes. Several field studies have also shown that testosterone levels increase during the aggressive phases of sports games. In more sensitive laboratory paradigms, it has been observed that participant's testosterone rises in the winners of; competitions, dominance trials or in confrontations with factitious opponents. Aggressive behavior arises in the brain through interplay between subcortical structures in the amygdala and the hypothalamus in which emotions are born and the prefrontal cognitive centers where emotions are perceived and controlled. The action of testosterone on the brain begins in the embryonic stage. Earlier in development at the DNA level, the number of CAG repeats in the androgen receptor gene seems to play a role in the expression of aggressive behavior. Neuroimaging techniques in adult males have shown that testosterone activates the amygdala enhancing its emotional activity and its resistance to prefrontal restraining control. This effect is opposed by the action of cortisol which facilitates prefrontal area cognitive control on impulsive tendencies aroused in the subcortical structures. The degree of impulsivity is regulated by serotonin inhibiting receptors, and with the intervention of this neurotransmitter the major agents of the neuroendocrine

    2015-01-01

    The aim of this article is study of the phenomenon of beauty in culture and aesthetic resources of social survival in changing world. In the broadest sense, beauty is a category indicating complete harmony in an object, based on an ideal correspondence of form and concept. Liberated by beauty, man recovers his lost link with nature and extends the boundaries of his existence. Aesthetic manifestations are very important resource of overcoming of crisis and social trials. Focusing on the charac...

  7. Unexpected trends in termite survival

    De Souza, O; Souza, Og De; Miramontes, Octavio

    2003-01-01

    Survival in groups of termites is known to be socially facilitated since individual longevity is increased together with the size of the group. Here we report on experimental evidence that survival as a function of group size in {textit Cornitermes cumulans} (Kollar) does not increase asysmptotically but it peaks in a group size range at which individual longevity is maximal. Strinkly, this same effect in other social insects was noted more than fifty years ago, but it was regarded as ``aberrant'' since it has been generally assumed that individual survival should increase with the size of the group. We also provide evidence that individual activity --measured as mobility-- is maximal at approximately the same group-size range as the observed survival

  8. Survivability of Deterministic Dynamical Systems.

    Hellmann, Frank; Schultz, Paul; Grabow, Carsten; Heitzig, Jobst; Kurths, Jürgen

    2016-01-01

    The notion of a part of phase space containing desired (or allowed) states of a dynamical system is important in a wide range of complex systems research. It has been called the safe operating space, the viability kernel or the sunny region. In this paper we define the notion of survivability: Given a random initial condition, what is the likelihood that the transient behaviour of a deterministic system does not leave a region of desirable states. We demonstrate the utility of this novel stability measure by considering models from climate science, neuronal networks and power grids. We also show that a semi-analytic lower bound for the survivability of linear systems allows a numerically very efficient survivability analysis in realistic models of power grids. Our numerical and semi-analytic work underlines that the type of stability measured by survivability is not captured by common asymptotic stability measures. PMID:27405955

    2015-01-01

    Recent studies claiming to revive ancient microorganisms trapped in fluid inclusions in halite have warranted an investigation of long-term microbial persistence. While starvation-survival is widely reported for bacteria, it is less well known for halophilic archaea—microorganisms likely to be trapped in ancient salt crystals. To better understand microbial survival in fluid inclusions in ancient evaporites, laboratory experiments were designed to simulate growth of halophilic archaea under m...

  10. Man-in-the-control-loop simulation of manipulators

    Chang, J. L.; Lin, Tsung-Chieh; Yae, K. Harold

    1989-01-01

    A method to achieve man-in-the-control-loop simulation is presented. Emerging real-time dynamics simulation suggests a potential for creating an interactive design workstation with a human operator in the control loop. The recursive formulation for multibody dynamics simulation is studied to determine requirements for man-in-the-control-loop simulation. High speed computer graphics techniques provides realistic visual cues for the simulator. Backhoe and robot arm simulations are implemented to demonstrate the capability of man-in-the-control-loop simulation.

  11. Man and Nature in Chinese and Western Traditions

    郑浩

    2008-01-01

    The Chinese conception of "oneness with man and heaven" and the Western tradition of man's separation from nature accompanied by a subject-object dichotomy are the cores of each culture, which largely decides the discrepancy in various aspects of the Chinese and Western ways. To have an embedded and penetrating idea about the differences between the two cultures, it is necessary to gain sufficient knowledge of man-nature relation in dominant Chinese and Western conceptions. This paper aims to explore this issue from the perspective of Taoism and Confucianism in Chinese context, and ancient Greek and Hebraic heritage and modern mechanical view in Western tradition.

  14. Effects and Complications of Bone-Marrow Transplantation in Man

    Full text: Allogenic bone-marrow grafting in 24 human leukaemic subjects is described. The graft failed in 7 cases and took in 17 cases. In the latter group, all 17 cases were complicated by the secondary syndrome which was-fatal in 13 cases and controlled in 4 cases. The immunogenetic and immunological factors determining the establishment and evolution of haematological radiochimeras in man are discussed. The choice of donor is fundamental. Three tests are effective in donor selection, the indirect histocompatibility test, the leucocyte antigen test and the reaction of donor and recipient leucocytes in the dermis of an irradiated hamster. When marrow from several donors is transfused, the recipient spontaneously selects the genetically nearest. It seems likely there is more chance of finding a suitable donor among genetically related subjects than among those who are unrelated. The frequency of graft take seems slightly lower in recipients who have previously received blood transfusions. Total bone-marrow graft is associated with specific tolerance towards donor tissues. This is paralleled by the production in the chimera of immunoglobulins produced by the graft. The secondary syndrome seems, as in animals, to be related essentially to the graft-versus-host reaction. It is convenient to distinguish among its various manifestations, on the one hand, those lesions which are readily controlled such as hepatitis or erythrodermia associated with infiltration and proliferation of immunologically competent cells from the graft and, on the other hand, immune insufficiency with regard to micro-organisms, especially viruses and Candida albicans. This latter group, the mechanism of which is complex, still eludes attempts at preventive and curative control. The use of multiple donors and the administration of cortisone during marrow transfusion and A-methopterin and/or cyclophosphamide in the days following transfusions; seem to have reduced the severity of the secondary

  15. Ion Inculetz- Political man and scientist

    Gaina, A.; Ionescu-Pallas, N. I.

    1993-06-01

    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

  16. A Man Who Cannot See Himself:Invisibility Caused by the Protago-nist’s Weakness in Invisible Man

    DU Juan

    2014-01-01

    Invisible Man is both a historical biography of the black man in America and an anguish process of man’s quest for identity in the dehumanizing and absurd society of racial discrimination. Personal weakness of the protagonist:his effort to evade his past functions as the last straw leading to his invisibility. Therefore, this paper tries to analyze the cause of the invisibility of the protagonist by further textual analysis in an attempt to reveal how a nameless African American reflects the existential crisis of modern man.

  17. Power system technologies for the manned Mars mission

    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. [Psychotherapeutic function of the South American medicine man].

    Stubbe, H

    1976-01-01

    Observing the medicine man system in South America from a psychological point of view, the function of the medicine man can be characterized as psychohygienic or psychotherapeutic; that is to say he employs many methods similar to modern psychotherapeutic ones. We know from many ethnological field research reports that the medicine man employs in his healing procedures - among other things - dream interpretation, (auto-) hynosis, and healing suggestion, advises the sick, uses imaginative techniques, and initiates group catharsis, i.e. he treats his patients by psychological means. The psychic disturbances which he treats concern less the individual but much more often the whole group. Here the medicine man must work as a regulator and valve for the group and try to equalize, to prevent and to heal all disturbances within the collective. PMID:1024011

  4. Conference on Manned Systems Design : New Methods and Equipment

    Kraiss, K-F

    1981-01-01

    This volume contains the proceedings of a conference held in Freiburg, West Germany, September 22-25, 1980, entitled "Manned Systems Design, New Methods and Equipment". The conference was sponsored by the Special Programme Panel on Human Factors of the Scientific Affairs Division of NATO, and supported by Panel VIII, AC/243, on "Human and Biomedical Sciences". Their sponsorship and support are gratefully acknowledged. The contributions in the book are grouped according to the main themes of the conference with special emphasis on analytical approaches, measurement of performance, and simulator design and evaluat ion. The design of manned systems covers many and highly diversified areas. Therefore, a conference under the general title of "Manned Systems Design" is rather ambitious in itself. However, scientists and engineers engaged in the design of manned systems very often are confronted with problems that can be solved only by having several disciplines working together. So it was felt that knowledge about ...

  5. The types and characteristics of man-induced sediment disaster

    2002-01-01

    The man-induced sediment disaster includes material erosion, transportation and accumula-tion by human activities. It possesses special attribute in sociology and disaster science. In accordancewith human activities, geomorphologic location, behavior and particular, the man-induced sedimentdisaster can be divided into 4 types: the drainage network, slope and gully, channel and plain-estu-au-coastline. Each type includes erosion, transportation, accumulation, complexity and cascading.Based on human activity, geomorphology, sediment mechanics and catastrophology, the man-inducedsediment disaster is characterized as follows: (1) accelerating tendency with geographical zoning back-ground; (2) non-order characters by blind action without special technical training; (3) gradually andsharply changing with human environment vibration; and (4) complexity and non-linear figure, etc.One of the reasons leading to man-induced sediment disaster is human environment vibration.

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

    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. PMID:26642730

    textabstractOBJECTIVES: In humans, fasting leads to elevated serum GH concentrations. Traditionally, changes in hypothalamic GH-releasing hormone and somatostatin release are considered as the main mechanisms that induce this elevated GH secretion during fasting. Ghrelin is an endogenous ligand of the GH secretagogue receptor and is synthesized in the stomach. As ghrelin administration in man stimulates GH release, while serum ghrelin concentrations are elevated during fasting in man, this in...

  15. Mars survival handbook: where to find water

    Marra, Wouter A.

    2015-04-01

    Most famous observations of Mars are those of Giovianni Schiaparelli in the late 19th century. His maps contain many linear features across the surface of Mars, which he called `canali'. The mis-translation from the Italian `canali', meaning channel, to the English `canal', man-made infrastructure, led to wild speculations of an advanced species struggling to survive on a planet with diminishing natural resources. Later research has proven this is not the case, at least not for Mars. Nevertheless, the possible existence of life and habitability of Mars has inspired further investigations, interplanetary missions and inevitably at some point human exploration. While no canals exist on Mars, there is widespread evidence for occurrence of liquid water a long time ago on this planet far, far away. The ancient landscapes of Mars may provide most valuable clues for answering the ultimate question about life, the universe and everything, but Mars today is a terrible place to be as it is extremely cold and dry; there may be life, but not as we know it. Nevertheless, many humans have volunteered to go there. Some call them mad, some call them heroes, but perhaps they just want to flee from our planet facing floods, droughts and climate change? But unless we find a good source of water for these explorers, the climate on Mars will certainly cause a swift EXTERMINATION! I have written my PhD thesis on groundwater outflow landscapes on Mars. I will review some of the most spectacular landscapes on Mars, experiments I have done in the past years to explain these landscapes and their hydrological and climate implications. Although the outlook is not so hopeful for early colonist, I will share my views on the possible sources of water on Mars today.

  16. Structural basis of carbohydrate recognition by a Man(alpha1-2)Man-specific lectin from Bowringia milbraedii.

    Buts, Lieven; Garcia-Pino, Abel; Wyns, Lode; Loris, Remy

    2006-07-01

    The crystal structure of the seed lectin from the tropical legume Bowringia milbraedii was determined in complex with the disaccharide ligand Man(alpha1-2)Man. In solution, the protein exhibits a dynamic dimer-tetramer equilibrium, consistent with the concanavalin A-type tetramer observed in the crystal. Contacts between the tetramers are mediated almost exclusively through the carbohydrate ligand, resulting in a crystal lattice virtually identical to that of the concanavalin-A:Man(alpha1-2)Man complex, even though both proteins have less than 50% sequence identity. The disaccharide binds exclusively in a "downstream" binding mode, with the non-reducing mannose occupying the monosaccharide-binding site. The reducing mannose is bound in a predominantly polar subsite involving Tyr131, Gln218, and Tyr219. PMID:16567368

    Objective: The purpose of this study was to determine whether the man to man training can improve the diagnostic performances and interobserver variabilities of residents on thyroid ultrasonography. Materials and methods: A set of 80 quiz cases with ultrasonography images of thyroid nodules (40 benign and 40 malignant on histopathology) were shown to the residents. Residents 1, 2, and 3 had not received the man to man training while Residents 4, 5, 6, and 7 had. The seven residents were asked to fill out one of the ultrasonography features (internal composition, echogenicity, margin, calcification, and shape) and the final assessment (probably benign and suspicious). Thyroid nodules with one or more ultrasonography features including marked hypoechogenicity, microlobulated or irregular margins, microcalcifications, and taller than wide shape were assessed as suspicious nodules. The diagnostic performances of US by the seven residents and interobserver variabilities between the seven residents and a faculty radiologist were calculated. Results: The sensitivities, negative predictive values, and accuracies of Residents 4, 5, 6, and 7 were higher than those of Residents 1, 2, and 3. The final assessment between Residents 4, 5, 6, and 7 and the faculty radiologist showed almost perfect agreement but that between Residents 1, 2, and 3 and the faculty radiologist showed substantial agreement. Conclusion: The man to man training is crucial for the residents to show better diagnostic performances and improvement of interobserver variabilities for evaluating thyroid nodules with ultrasonography.

  20. Medieval Sport: Quest for Survival.

    Wiseman, Douglas C.

    Since the Middle Ages, sport has survived because of its masochistic and sadistic components. The Greeks, who organized athletic contests into the Olympic Games in 776 B.C., emphasized the relationship between the mind and the body and fair competition, rather than putting emphasis on winning or losing. The Romans preferred the spectacle of…

  1. Cool echidnas survive the fire.

    Nowack, Julia; Cooper, Christine Elizabeth; Geiser, Fritz

    2016-04-13

    Fires have occurred throughout history, including those associated with the meteoroid impact at the Cretaceous-Palaeogene (K-Pg) boundary that eliminated many vertebrate species. To evaluate the recent hypothesis that the survival of the K-Pg fires by ancestral mammals was dependent on their ability to use energy-conserving torpor, we studied body temperature fluctuations and activity of an egg-laying mammal, the echidna (Tachyglossus aculeatus), often considered to be a 'living fossil', before, during and after a prescribed burn. All but one study animal survived the fire in the prescribed burn area and echidnas remained inactive during the day(s) following the fire and substantially reduced body temperature during bouts of torpor. For weeks after the fire, all individuals remained in their original territories and compensated for changes in their habitat with a decrease in mean body temperature and activity. Our data suggest that heterothermy enables mammals to outlast the conditions during and after a fire by reducing energy expenditure, permitting periods of extended inactivity. Therefore, torpor facilitates survival in a fire-scorched landscape and consequently may have been of functional significance for mammalian survival at the K-Pg boundary. PMID:27075255

    2016-05-01

    Glioblastoma is the most common and most aggressive primary brain tumour. Standard of care consists of surgical resection followed by radiotherapy and concomitant and maintenance temozolomide (temozolomide/radiotherapy→temozolomide). Corticosteroids are commonly used perioperatively to control cerebral oedema and are frequently continued throughout subsequent treatment, notably radiotherapy, for amelioration of side effects. The effects of corticosteroids such as dexamethasone on cell growth in glioma models and on patient survival have remained controversial. We performed a retrospective analysis of glioblastoma patient cohorts to determine the prognostic role of steroid administration. A disease-relevant mouse model of glioblastoma was used to characterize the effects of dexamethasone on tumour cell proliferation and death, and to identify gene signatures associated with these effects. A murine anti-VEGFA antibody was used in parallel as an alternative for oedema control. We applied the dexamethasone-induced gene signature to The Cancer Genome Atlas glioblastoma dataset to explore the association of dexamethasone exposure with outcome. Mouse experiments were used to validate the effects of dexamethasone on survival in vivo Retrospective clinical analyses identified corticosteroid use during radiotherapy as an independent indicator of shorter survival in three independent patient cohorts. A dexamethasone-associated gene expression signature correlated with shorter survival in The Cancer Genome Atlas patient dataset. In glioma-bearing mice, dexamethasone pretreatment decreased tumour cell proliferation without affecting tumour cell viability, but reduced survival when combined with radiotherapy. Conversely, anti-VEGFA antibody decreased proliferation and increased tumour cell death, but did not affect survival when combined with radiotherapy. Clinical and mouse experimental data suggest that corticosteroids may decrease the effectiveness of treatment and shorten

  4. Small reactor power systems for manned planetary surface bases

    A preliminary feasibility study of the potential application of small nuclear reactor space power systems to manned planetary surface base missions was conducted. The purpose of the study was to identify and assess the technology, performance, and safety issues associated with integration of reactor power systems with an evolutionary manned planetary surface exploration scenario. The requirements and characteristics of a variety of human-rated modular reactor power system configurations selected for a range of power levels from 25 kWe to hundreds of kilowatts is described. Trade-off analyses for reactor power systems utilizing both man-made and indigenous shielding materials are provided to examine performance, installation and operational safety feasibility issues. The results of this study have confirmed the preliminary feasibility of a wide variety of small reactor power plant configurations for growth oriented manned planetary surface exploration missions. The capability for power level growth with increasing manned presence, while maintaining safe radiation levels, was favorably assessed for nominal 25 to 100 kWe modular configurations. No feasibility limitations or technical barriers were identified and the use of both distance and indigenous planetary soil material for human rated radiation shielding were shown to be viable and attractive options

  5. CAECUM AND APPENDIX IN RUMINANTS AND MAN: A COMPARATIVE STUDY

    Sreekanth

    2014-07-01

    Full Text Available The change in the trends of living and dietary habits prompted the inquisitiveness in finding out if there are obvious changes in the gastrointestinal tract of ruminants. Ruminants are entirely dependent on the environment for their food and take a long time to feed themselves with foliage which is first taken in and then digested. The changing ecological balance and dwindling reserves in the past few years and changing climatic conditions could probably have an effect on the digestive tract. It has been observed that the cow, sheep and goat have started feeding on debris from the environment. Man has also started changing dietary habits according to convenience and has become aware of organic foods and vegetarian diets. Therefore an attempt was made to see if there are notable changes that can be recorded in the digestive tract. The study here attempted to compare the caecum of man with that of ruminants. The caecum was found to be the largest in the cow in proportion to the weight of the animal. The caecum was almost of the same dimensions in goat and sheep compared with that of man. The appendix was noted only in man. The study attempts to describe the importance of appendix in man and a large caecum in ruminants.

  6. Food concentrations and dietary intakes of elements for Chinese man

    Objective: To obtain concentrations of elements in Chinese current foods and their dietary intakes by adult man in order to provide a basis on intake parameters of Chinese Reference Man and make related hygienic evaluation. Methods: With mixed food sample method of total diet study, determination of element concentrations in constituent foods of diets for 4 areas with different diet types was carried out by using NAA, ICP-MS, ICP-AES, AAS and necessary QA measures, and estimation of their daily intakes and hygienic evaluation were also made. Results: The concentrations of 42 elements in 12 categories of foods, their intakes and hygienic evaluation for adult man were obtained. Conclusion: The data on element concentrations in Chinese foods and their dietary intakes were updated and widened. These data provided a new basis for developing the parameters of Chinese Reference Man and revealed some current hygienic problems. For example, from viewpoint of nutrition hygiene the Ca, Zn, and Cu intakes for Chinese Reference Man are insufficient, and from consideration of food hygiene the intakes of Pb,Cd and Na are excessive.. Especially, and Cd average daily intakes of Pb, Cd and Hg have been increased during recent years, those of Pb exceed their ADIs, which should be paid attention to

  8. The character of the real man and the symbolic meanings in the old man and sea

    李雪

    2011-01-01

    In The Old Man and the Sea by Hemingway, we can see Santiago who is the one that generalized and highlighted the characters of braveness, confidence, and perseverance. Santiago is optimistic and held a firm and resolute attitude toward life from the beginning to the end, as an undefeated hero. The character portrayed in the novel is successful. Hemingway uses the writing skill of Iceberg to depict the story. The Author tries to convey his dissatisfaction toward the society through the symbolic things.%在海明威写的《老人与海》中,我们能够发现圣地阿哥高度集中了勇敢,自信,坚持不懈等这些性格特征。圣地阿哥从头到尾就像一个打不败的英雄,一直积极乐观,意志力坚强。小说对人物特征的塑造是成功的。海明成使用了“冰山理论”的创作原则。作者就试图以这些象征的物体来表达他对社会的不满。

  9. EMMI - Electric Solar Wind Sail Facilitated Manned Mars Initiative

    Janhunen, Pekka; Paton, Mark

    2014-01-01

    The novel propellantless electric solar wind sail (E-sail) concept promises efficient low thrust transportation in the solar system outside Earth's magnetosphere. Combined with asteroid mining to provide water and synthetic cryogenic rocket fuel in orbits of Earth and Mars, possibilities for affordable continuous manned presence on Mars open up. Orbital fuel and water eliminate the exponential nature of the rocket equation and also enable reusable bidirectional Earth-Mars vehicles for continuous manned presence on Mars. Water can also be used as radiation shielding of the manned compartment, thus reducing the launch mass further. In addition, the presence of fuel in Mars orbit provides the option for an all-propulsive landing, thus potentially eliminating issues of heavy heat shields and augmenting the capability of pinpoint landing. With this E-sail enabled scheme, the recurrent cost of continuous bidirectional traffic between Earth and Mars might ultimately approach the recurrent cost of running the Interna...

  10. Distribution of man-machine controls in space teleoperation

    Bejczy, A. K.

    1982-01-01

    The distribution of control between man and machine is dependent on the tasks, available technology, human performance characteristics and control goals. This dependency has very specific projections on systems designed for teleoperation in space. This paper gives a brief outline of the space-related issues and presents the results of advanced teleoperator research and development at the Jet Propulsion Laboratory (JPL). The research and development work includes smart sensors, flexible computer controls and intelligent man-machine interface devices in the area of visual displays and kinesthetic man-machine coupling in remote control of manipulators. Some of the development results have been tested at the Johnson Space Center (JSC) using the simulated full-scale Shuttle Remote Manipulator System (RMS). The research and development work for advanced space teleoperation is far from complete and poses many interdisciplinary challenges.

  11. The CANDU man-machine interface and simulator training

    The most significant features of the man-machine interface for CANDU power stations are the extensive use of computer-driven colour graphics displays and the small number of manual controls. The man-machine interface in CANDU stations is designed to present the operator with concise, easy-to-understand information. Future developments in the use of computers in safety shutdown systems, and the use of data highway technologies in plant regulating systems will present special requirements and new opportunities in the application of human factors engineering to the control room. Good man-machine interaction depends on operator training as much as on control room design. In Canada computerized training simulators, which indicate plant response to operator action, are being introducted for operator training. Such simulators support training in normal operation of all plant systems and also in the fault management tasks following malfunctions

  12. Nuclear-electric propulsion - Manned Mars propulsion options

    Palaszewski, Bryan; Brophy, John; King, David

    1989-01-01

    Nuclear-electric propulsion can significantly reduce the launch mass for manned Mars missions. By using high-specific-impulse (lsp) electric propulsion systems with advanced nuclear reactors, the total mass-to-orbit for a series of manned Mars flight is reduced. Propulsion technologies required for the manned Mars mission are described. Multi-megawatt Ion and Magneto-Plasma-Dynamic (MPD) propulsion thrusters, Power-Processing Units and nuclear power source are needed. Xenon (Xe)-Ion and MPD thruster performance are detailed. Mission analyses for several Mars mission options are addressed. Both MPD and Ion propulsion were investigated. A four-megawatt propulsion system power level was assumed. Mass comparisons for all-chemical oxygen/hydrogen propulsion missions and combined chemical and nuclear-electric propulsion Mars fleets are included. With fleets of small nuclear-electric vehicles, short trip times to Mars are also enabled.

  13. Kant's BetterMan and the Confucian Junzi

    XIEWenyu

    2012-01-01

    This essay attempts to compare Kant's better man and the Confucian junzi in the Zhongyong, and argues that Kant's idea of the better man, which expresses human self-improvement in ultimate freedom, is in fact a conception very similar to that of the Confucian junzi, which denotes an ideal human being in cheng. Kant attributes the lack of emphasis on self-improvement in Westem culture to the Christian conception of grace, and demonstrates the possibility of self-improvement on the ground of ultimate freedom. We may call this treatment "the Confucian solution" in Kant's thought. My intention is to explicate the conceptual commonality between the better man and the junzi and demonstrate the Confucian element in Kant's religious thought.

  14. Nuclear power--key to man's extraterrestrial civilization

    The start of the Third Millennium will be highlighted by the establishment of man's extraterrestrial civilization with three technical cornerstones leading to the off-planet expansion of the human resource base. These are the availability of compact energy sources for power and propulsion, the creation of permanent manned habitats in space, and the ability to process materials anywhere in the Solar System. In the 1990s and beyond, nuclear reactors could represent the prime source of both space power and propulsion. The manned and unmanned space missions of tomorrow will demand first kilowatt and then megawatt levels of power. Various nuclear power plant technologies are discussed, with emphasis on derivatives from the nuclear rocket technology

  15. Reference Man for Asians as well as for Europeans-A change in the ICRP concept of Reference Man

    ICRP Reference Man, according to the definition, is primarily for Caucasoid populations (Western Europeans and North Americans) that contribute only 13 per cent of the world population. A speculative world population dose will, assuming a uniform exposure all over the world at a level of 10 μSv, be 50 k man Sv in total. Of this, all regions of Caucasoid populations may contribute by 22 per cent maximum. Asian populations will share about 58 per cent (29 k man Sv) of the world population dose. About eighty per cents in total of the world population can be convered by scientific dose assessment, if Reference Man data for Asians are made available. Thus the importance of establishing Asian Reference Man should be evident. The important point of characteristics of Asians is that they are 'Vegetarians' as compared to Westerners, which suggests different pathways with respect to transfer of radionuclides from foods to the human body. Therefore it is required to determine accurate and suitable parameters relevant to dose assessment. Considering the above, contribution of Japan in science and technology to Asian countries with 'knowhows' accumulated may be of a most urgent matter. (author)

  16. MANNED OR UNMANNED – DOES THIS REALLY MATTER?

    B. Neininger

    2012-09-01

    Full Text Available This paper is an attempt to compare, and possibly combine, the capabilities and technologies available for using either small UAS or small manned aircraft, or both, for environmental research applications including geomatics. The paper is emphasising the view that instead of making one or the other platform technology (manned or unmanned the deciding factor for specific applications in an a priori sense, it would be a better approach to evaluate each technology's suitability and merits in terms of ease of use (instrumentation integration, operational aspects, potential restrictions, safety, etc. and also cost-efficiency. As will be shown, in some cases, this might even mean that a combination of manned and unmanned aerial platforms could be the optimum choice for a specific set of tasks. The paper introduces a number of manned and unmanned small aerial platforms and looks at their specific proven and envisaged capabilities for specific tasks. It also introduces the concept of using manned and unmanned aerial platform in tandem, maximising the usefulness of both technologies together for specific tasks. The authors' intent is to encourage a close look at all technologies available today, or in the near future, and to make that the basis for decisions about which ones are the most suitable ones for specific applications or projects. Two field campaigns in which METAIR and ARA have operated their small manned aerial platforms are re-analysed to give an example of the considerations that should be evaluated to decide which platform technology might be the most suitable one for a specific project. One of the projects ("TIPPEX" was flown in 2008 in Northern Australia, while the other one ("MAIOLICA" had flight campaigns in 2009 and 2011 in Switzerland.

  17. Different Rebellions--The and the Angry Beat Generation Man

    欧国芳

    2012-01-01

    The Beat Generation (BG) and the Angry Man (AYM) both emerged after the Second World War. Thus, the misunderstanding of the two has existed for a long time. Large quantities of people called the BG the American Angry Young Man. Undoubtedly, the two resembled each other to some extent. However, the BG and the AYM can't be treated alike, for their differences far outweighed their similarities. This paper aims to analyze their differences in many aspects like the national environment and their memberships, which consequently led to other differences such as the differences in essences, features, influence and finale.

  19. The multi-axis vibration environment and man.

    Lovesey, E J

    1970-12-01

    Many investigations into the effects of vibration on man have been performed since Mallock's first study of London Underground vibrations in 1902. The vibration research has tended to be confined to the vertical (heave) axis, yet recent experiments have indicated that low frequency vibration along the lateral (sway) axis has a greater adverse effect upon comfort and performance. Measurements of the vibration environments in current forms of transport including motor vehicles, hovercraft and aircraft etc have shown that appreciable quantities of vibration along all three axes exist. Further vibration research should consider the effects of multi-axis vibrations upon man rather than limit tests to single axis vibration. PMID:15676336

  20. Review on abort trajectory for manned lunar landing mission

    2010-01-01

    Abort trajectory is a passage that ensures the astronauts to return safely to the earth when an emergency occurs. Firstly,the essential elements of mission abort are analyzed entirely based on summarizing the existing studies. Then,abort trajectory requirement and rational selection for different flight phases of typical manned lunar mission are discussed specifically. Considering a trade-off between the two primary constrains of an abort,the return time of flight and energy requirement,a general optimizing method for mission abort is proposed. Finally,some suggestions are given for China’s future manned lunar landing mission.

  1. Proposed man-rem reference values of occupational exposure

    This report presents a proposal of referent collective dose (man-rem) values for occupational exposure related to operation of French pressurized water reactors. These values, permitting adequate choice of protection both at design and operation level, are dependent on the level of annual individual doses. The man-rem value, originating from annual individual doses less than 0.5 rem are estimated to 1 kf. The proposed value is 20 kf for annual individual exposures between 0.5 and 3 rem, and 90 kf for annual individual exposures between 3 and 5 rem. (author)

    U. Villante

    2004-04-01

    Full Text Available An analysis of the man made contamination on ULF measurements in highly populated areas has been conducted at several suitably chosen sites in Western Europe. The experimental results show common characteristics at different stations with clear evidence for an additional working day contamination with respect to weekends. These effects more clearly emerge in the vertical component that is less influenced by natural signals. A similar analysis conducted at Terra Nova Bay does not reveal any clear evidence for man made disturbances on Antarctic measurements.

    Full Text Available This article examines how the Isle of Man, a self-governing crown dependency located in the center of the British Isles, uses heritage to create social stability among a diverse and rapidly changing population. The result of this process has been a powerful model of heritage branding through which all definitions of national identity must flow. After tracing the development of ‘Manx’ national identity from the Victorian era to the present, this article explores the benefits and limitations of the Isle of Man’s political uses of its history and shares insight from the practice of public history on the Isle of Man.

  10. Mechanical Properties of Man-Made Mineral glass fibres

    Lund, Majbritt Deichgræber; Yue, Yuanzheng

    In nature basaltic volcanic glass fibres are know from Hawaii as Pele's hair, formed by droplets of lava thrown into the air during volcanic eruption. The concept of glass fibre formation by an air stream dragging fibres from drops of melt is copied in industry to form basaltic glass wool fibres...... and hence they are used for insulation products. In spite of those advantages, man made mineral wool fibres still show a certain degree of brittleness, which limits the further improvement of man made mineral wool fibres for both transportation and application. Therefore, a reduction in the...

  11. Complexity for survival of livings

    A connection between survivability of livings and complexity of their behavior is established. New physical paradigms-exchange of information via reflections, and chain of abstractions-explaining and describing progressive evolution of complexity in living (active) systems are introduced. A biological origin of these paradigms is associated with a recently discovered mirror neuron that is able to learn by imitation. As a result, an active element possesses the self-nonself images and interacts with them creating the world of mental dynamics. Three fundamental types of complexity of mental dynamics that contribute to survivability are identified. Mathematical model of the corresponding active systems is described by coupled motor-mental dynamics represented by Langevin and Fokker-Planck equations, respectively, while the progressive evolution of complexity is provided by nonlinear evolution of probability density. Application of the proposed formalism to modeling common-sense-based decision-making process is discussed

  12. Additive interaction in survival analysis

    Rod, Naja Hulvej; Lange, Theis; Andersen, Ingelise;

    2012-01-01

    It is a widely held belief in public health and clinical decision-making that interventions or preventive strategies should be aimed at patients or population subgroups where most cases could potentially be prevented. To identify such subgroups, deviation from additivity of absolute effects is the...... relevant measure of interest. Multiplicative survival models, such as the Cox proportional hazards model, are often used to estimate the association between exposure and risk of disease in prospective studies. In Cox models, deviations from additivity have usually been assessed by surrogate measures of...... additive interaction derived from multiplicative models-an approach that is both counter-intuitive and sometimes invalid. This paper presents a straightforward and intuitive way of assessing deviation from additivity of effects in survival analysis by use of the additive hazards model. The model directly...

  13. Bacterial survival in Martian conditions

    D'Alessandro, Giuseppe Galletta; Giulio Bertoloni; Maurizio

    2010-01-01

    We shortly discuss the observable consequences of the two hypotheses about the origin of life on Earth and Mars: the Lithopanspermia (Mars to Earth or viceversa) and the origin from a unique progenitor, that for Earth is called LUCA (the LUCA hypothesis). To test the possibility that some lifeforms similar to the terrestrial ones may survive on Mars, we designed and built two simulators of Martian environments where to perform experiments with different bacterial strains: LISA and mini-LISA. Our LISA environmental chambers can reproduce the conditions of many Martian locations near the surface trough changes of temperature, pressure, UV fluence and atmospheric composition. Both simulators are open to collaboration with other laboratories interested in performing experiments on many kind of samples (biological, minerals, electronic) in situations similar to that of the red planet. Inside LISA we have studied the survival of several bacterial strains and endospores. We verified that the UV light is the major re...

  14. 51Cr - erythrocyte survival curves

    Sixteen patients were studied, being fifteen patients in hemolytic state, and a normal individual as a witness. The aim was to obtain better techniques for the analysis of the erythrocytes, survival curves, according to the recommendations of the International Committee of Hematology. It was used the radiochromatic method as a tracer. Previously a revisional study of the International Literature was made in its aspects inherent to the work in execution, rendering possible to establish comparisons and clarify phonomena observed in cur investigation. Several parameters were considered in this study, hindering both the exponential and the linear curves. The analysis of the survival curves of the erythrocytes in the studied group, revealed that the elution factor did not present a homogeneous answer quantitatively to all, though, the result of the analysis of these curves have been established, through listed programs in the electronic calculator.

    1990-01-01

    One form of commercial application of microorganisms, including genetically engineered microorganisms is as an aerosol. To study the effect of aerosol-induced stress on bacterial survival, nonrecombinant spontaneous antibiotic-resistant mutants of four organisms, Enterobacter cloacae, Erwinia herbicola, Klebsiella planticola, and Pseudomonas syringae, were sprayed in separate experiments in a greenhouse. Samples were collected over a distance of 15 m from the spray site for enumeration. Spore...

  18. LATERAL SURVIVAL: AN OT ACCOUNT

    Moira Yip

    2004-12-01

    Full Text Available When laterals are the targets of phonological processes, laterality may or may not survive. In a fixed feature geometry, [lateral] should be lost if its superordinate node is eliminated by either the spreading of a neighbouring node, or by coda neutralization. So if [lateral] is under Coronal (Blevins 1994, it should be lost under Place assimilation, and if [lateral] is under Sonorant Voicing (Rice & Avery 1991 it should be lost by rules that spread voicing. Yet in some languages lateral survives such spreading intact. Facts like these argue against a universal attachment of [lateral] under either Coronal or Sonorant Voicing, and in favour of an account in terms of markedness constraints on feature-co-occurrence (Padgett 2000. The core of an OT account is that IFIDENTLAT is ranked above whatever causes neutralization, such as SHARE-F or *CODAF. laterality will survive. If these rankings are reversed, we derive languages in which laterality is lost. The other significant factor is markedness. High-ranked feature co-occurrence constraints like *LATDORSAL can block spreading from affecting laterals at all.

  9. Heavy metal pollution of man and environment - A historical perspective

    'Normal' levels of heavy metals are disturbingly close to toxic levels. This may be a man-made or natural phenomenon. The man-made exposure to heavy metals started thousands of years ago. In some European populations in the past the lead level was orders of magnitude higher than now, where it is comparable with the prehistoric level. The former high contamination of human populations was due to intake of metals from immediate sources (utensils, drugs, etc) not to their dispersion in the environment. A dramatic decrease of lead level in man occurred recently, when the majority of the immediate sources disappeared, but when at the local (but not at the global) scale the environmental level of metals increased. The current flow of metals into the global atmosphere, similar to the pre-industrial flow, is still dominated by natural processes, such as biological methylization of metals. This leads to an enrichment of the airborne particles in metals up to several orders of magnitude above the crustal abundances. It is not the magnitude of emissions of metals into the global atmosphere that marks a new role of man in the biosphere, but the mass of anthropogenic mobilization of raw materials now reaching the geological dimensions.

  15. Natural and man-made terrestrial electromagnetic noise: an outlook

    A. Meloni

    2007-06-01

    Full Text Available The terrestrial environment is continuously exposed to electromagnetic radiations which set up a «background» electromagnetic noise. Within the Non Ionizing Radiation band (NIR, i.e. for frequencies lower than 300 GHz, this background can have a natural or an artificial origin. Natural origins of electromagnetic radiations are generally atmospheric or cosmic while artificial origins are technological applications, power transmission, communications, etc. This paper briefly describes the natural and man-made electromagnetic noise in the NIR band. Natural noise comes from a large variety of sources involving different physical phenomena and covering a wide range of frequencies and showing various propagation characteristics with an extremely broad range of power levels. Due to technological growth man-made electromagnetic noise is nowadays superimposed on natural noise almost everywhere on Earth. In the last decades man-made noise has increased dramatically over and above the natural noise in residential and business areas. This increase has led some scientists to consider possible negative effects of electromagnetic waves on human life and living systems in general. Accurate measurements of natural and man-made electromagnetic noise are necessary to understand the relative power levels in the different bands and their influence on life.

  19. Not normally manned compression platforms for the North Sea

    Gas turbine driven gas compressors have been widely used on manned offshore facilities. Similarly unmanned gas turbine driven compressor stations have been in operation onshore with major gas transmission companies in Europe, North America and elsewhere. This paper summarizes a recent joint industry study to investigate the technical and economic feasibility of Not Normally Manned (NNM) Offshore Compression Facilities in terms of reliability, availability and maintainability. Classification of not normally manned (or unmanned) offshore facilities in the UK North Sea is in accordance with HSE Operations Notice 8. ON8 specifies criteria for offshore visits, visit hours and number of personnel on board for the operation of NNM platforms. This paper describes a typical Southern North Sea gas platform being considered for NNM compressor application. The conclusions from the study was that NNM compression is technically feasible with the facilities being able to provide an availability in excess of 98%. Life cycle costs were of the order of 70% of manned facilities thus significantly improving field development economics

  10. Starvation-Survival in Haloarchaea

    Yaicha D. Winters

    2015-11-01

    Full Text Available Recent studies claiming to revive ancient microorganisms trapped in fluid inclusions in halite have warranted an investigation of long-term microbial persistence. While starvation-survival is widely reported for bacteria, it is less well known for halophilic archaea—microorganisms likely to be trapped in ancient salt crystals. To better understand microbial survival in fluid inclusions in ancient evaporites, laboratory experiments were designed to simulate growth of halophilic archaea under media-rich conditions, complete nutrient deprivation, and a controlled substrate condition (glycerol-rich and record their responses. Haloarchaea used for this work included Hbt. salinarum and isolate DV582A-1 (genus Haloterrigena sub-cultured from 34 kyear Death Valley salt. Hbt. salinarum and DV582A-1 reacted to nutrient limitation with morphological and population changes. Starved populations increased and most cells converted from rods to small cocci within 56 days of nutrient deprivation. The exact timing of starvation adaptations and the physical transformations differed between species, populations of the same species, and cells of the same population. This is the first study to report the timing of starvation strategies for Hbt. salinarum and DV582A-1. The morphological states in these experiments may allow differentiation between cells trapped with adequate nutrients (represented here by early stages in nutrient-rich media from cells trapped without nutrients (represented here by experimental starvation in ancient salt. The hypothesis that glycerol, leaked from Dunaliella, provides nutrients for the survival of haloarchaea trapped in fluid inclusions in ancient halite, is also tested. Hbt. salinarum and DV582A-1 were exposed to a mixture of lysed and intact Dunaliella for 56 days. The ability of these organisms to utilize glycerol from Dunaliella cells was assessed by documenting population growth, cell length, and cell morphology. Hbt. salinarum

  13. Crossover studies with survival outcomes.

    Buyze, Jozefien; Goetghebeur, Els

    2013-12-01

    Crossover designs are well known to have major advantages when comparing the effect of two treatments which do not interact. With a right-censored survival endpoint, however, this design is quickly abandoned in favour of the more costly parallel design. Motivated by human immunodeficiency virus (HIV) prevention studies which lacked power, we evaluate what may be gained in this setting and compare parallel with crossover designs. In a heterogeneous population, we find and explain a substantial increase in power for the crossover study using a non-parametric logrank test. With frailties in a proportional hazards model, crossover designs equally lead to substantially smaller variance for the subject-specific hazard ratio (HR), while the population-averaged HR sees negligible gain. Its efficiency benefit is recovered when the population-averaged HR is reconstructed from estimated subject-specific hazard rates. We derive the time point for treatment crossover that optimizes efficiency and end with the analysis of two recent HIV prevention trials. We find that a Cellulose sulphate trial could have hardly gained efficiency from a crossover design, while a Nonoxynol-9 trial stood to gain substantial power. We conclude that there is a role for effective crossover designs in important classes of survival problems. PMID:21715438

  14. Survival analysis of aging aircraft

    Benavides, Samuel

    This study pushes systems engineering of aging aircraft beyond the boundaries of empirical and deterministic modeling by making a sharp break with the traditional laboratory-derived corrosion prediction algorithms that have shrouded real-world failures of aircraft structure. At the heart of this problem is the aeronautical industry's inability to be forthcoming in an accurate model that predicts corrosion failures in aircraft in spite of advances in corrosion algorithms or improvements in simulation and modeling. The struggle to develop accurate corrosion probabilistic models stems from a multitude of real-world interacting variables that synergistically influence corrosion in convoluted and complex ways. This dissertation, in essence, offers a statistical framework for the analysis of structural airframe corrosion failure by utilizing real-world data while considering the effects of interacting corrosion variables. This study injects realism into corrosion failures of aging aircraft systems by accomplishing four major goals related to the conceptual and methodological framework of corrosion modeling. First, this work connects corrosion modeling from the traditional, laboratory derived algorithms to corrosion failures in actual operating aircraft. This work augments physics-based modeling by examining the many confounding and interacting variables, such as environmental, geographical and operational, that impact failure of airframe structure. Examined through the lens of censored failure data from aircraft flying in a maritime environment, this study enhances the understanding between the triad of the theoretical, laboratory and real-world corrosion. Secondly, this study explores the importation and successful application of an advanced biomedical statistical tool---survival analysis---to model censored corrosion failure data. This well-grounded statistical methodology is inverted from a methodology that analyzes survival to one that examines failures. Third, this

    Cirillo, William M.; Troutman, Patrick A.; Brender, Karen D.; Dahlstrom, Eric L.; Ayers, J. Kirk; Waters, Laura M.

    1990-01-01

    In order to establish bases on the lunar and Mars surfaces, a significant amount of orbital infrastructure including assembly platforms, cryogenic fluids depots, and Space Station Freedom, will be required in LEO. These facilities will be required to perform a myriad of functions ranging from orbital demonstration of advanced technology systems and establishment of life science capabilities to servicing and refurbishment of reusable lunar transfer vehicles. This paper addresses the requirements levied on these facilities and provides an overview of potetial LEO infrastructure elements that satisfy various advanced manned missions. Of key importance to the success of the manned lunar mission are (1) the evolutionary growth of Space Station Freedom to serve as a transportation node and (2) the development of a Shuttle-derived launch vehicle to deliver mission elements to LEO.

    This paper presents a methodology to identify Man-Machine Task Allocation in nuclear power plant operation based on fuzzy measures and fuzzy integral. By means of the method, subjective judgements by human experts are systematically derived. First, experts are interviewed for actual operation environment with an interview scheme based on a tree structured evaluation system. Fuzzy analysis to model the structures of the each expert's consciousness for the environment is performed based on the interviews' results. Further, two dimensional map representation of the structures is introduced to derive individual criteria of Man-Machine Task Allocation. Lastly, total discussions among the experts are conducted to evaluate the individual criteria and integrate them. (author)

  19. Correction factors for gravimetric measurement of peritumoural oedema in man.

    Bell, B A; Smith, M A; Tocher, J L; Miller, J D

    1987-01-01

    The water content of samples of normal and oedematous brain in lobectomy specimens from 16 patients with cerebral tumours has been measured by gravimetry and by wet and dry weighing. Uncorrected gravimetry underestimated the water content of oedematous peritumoural cortex by a mean of 1.17%, and of oedematous peritumoural white matter by a mean of 2.52%. Gravimetric correction equations calculated theoretically and from an animal model of serum infusion white matter oedema overestimate peritumoural white matter oedema in man, and empirical gravimetric error correction factors for oedematous peritumoural human white matter and cortex have therefore been derived. These enable gravimetry to be used to accurately determine peritumoural oedema in man. PMID:3268140

  20. [Philosophy of the mutual biotic system of man-environment].

    Mertz, D P

    2009-06-01

    With regard to environmental changes, outstanding importance is meanwhile to be attached to the cultural side of human evolution. The evolution both of mankind and of its environment are mutually dependent as processes of change and together they form a complete biotic system. First disorders of balance concerning the close relationship network between mankind and environment eventually developed following man's change from the biosphere to the "noosphere" created by him. In the course of the "neolithic revolution" mankind, while becoming more and more settled, began to become increasingly estranged from its ecological surroundings. Environmental problems caused by man led to climatic changes already about 8,000 years ago. So far they have caused an extraordinary climatic stability following the Ice Age. "Environmental art" i. e. an improved evolution - is required to escape an imminent "collapse" caused by pollution. Nowadays mankind is on the way to being the almost exclusive carrier of future evolution of this planet. PMID:19544720

  1. Man-made mineral fibers and the respiratory tract.

    Costa, Roser; Orriols, Ramon

    2012-12-01

    Man-made mineral fibers are produced using inorganic materials and are widely used as thermal and acoustic insulation. These basically include continuous fiberglass filaments, glass wool (fiberglass insulation), stone wool, slag wool and refractory ceramic fibers. Likewise, in the last two decades nanoscale fibers have also been developed, among these being carbon nanotubes with their high electrical conductivity, mechanical resistance and thermal stability. Both man-made mineral fibers and carbon nanotubes have properties that make them inhalable and potentially harmful, which have led to studies to assess their pathogenicity. The aim of this review is to analyze the knowledge that currently exists about the ability of these fibers to produce respiratory diseases. PMID:22763045

  2. A Functional Analysis of The old Man and the Sea

    马菊玲

    2005-01-01

    The present paper is a stylistic analysis of the novel The Old Man and the Sea from functional perspective. It places context of situation and modified transitivity into stylistic analysis. The paper aims to put functional linguistics into practice and offer a new insight into the novel. It first gives a situational description of the novel and collects the data accordingly,and then analyzes the materiality of the samples in detail. By comparing the four samples, the paper first works out the plot, which is considered congruent with the principle of data collection; and then it discovers double levels of literary themes of the novel A man may be destroyed but not defeated on one level, and the relationship between human being and non -human being on the highest level.

  3. Hematologic syndrome in man modeled from mammalian lethality

    Data on acute radiation lethality due to failure of the hematologic system in rats, mice, dogs, swine, monkeys and man are analyzed. Based on the available data, the mortality incidences for 1-100% levels can be computed directly if one has only an estimate of the dose lethal to 50% of the population (LD50) for the mammalian strain and radiation environment of interest. The sole restriction is that the dose profile to the marrow be moderately uniform. If an LD50 for any exposure situation has been measured, then one can readily scale to any desired situation through implicit-biological and empirical-physical relationships. The LD50 for man, exposed to an isotropic cloud of photons, and knowledge of the bone-marrow dose profiles readily permit evaluation of the model for other levels of human mortality from different irradiating particles, partial body irradiation and spatially dependent and/or mixed radiation environments.

  4. Temporality in“A Good Man is Hard to Find”

    LIU Shuai-yi

    2014-01-01

    As a carefully designed work, Flannert O’Connor’s short story“A Good Man is Hard to Find”is a brilliant example for skillfully using narrative techniques to convey her Catholic faith. Mieke Bal’s theories of time in narratology provide a fresh perspective to explores the characterizations in Flannert O’Connor’s“A Good Man is Hard to Find”. Time functions greatly to the characterizations of the characters through the narrative text in terms of the story and the fabula. It helps to present the charac⁃ters’personalities by playing with the sequential ordering, rhythm and frequency. By using these narrative techniques, grand⁃mother’s selfishness, her moral inanition and her considerations that she is morally superior to others is fully expressed to the read⁃er as well as Misfit’s struggling and renascence to his disbeliefs of God and so on.

  5. Study on the setting of Reference Chinese man

    The procedures for internal and external dose estimation, the calculation of authorized limits and derived reference levels, and the development of phantoms in the field of radiation protection are based on values for the ICRP Reference Man. Many differences exist between Asians, Europeans and North Americans with respect to race, customs and the pattern of food consumption. The neglect of these differences in the parameters used may lead to errors in dose assessment and health effect prognosis. research described in this paper was conducted to obtain reference values for the Chinese population or other Asian countries which might have major demographic contribution of Chinese. Based on the agreements reached in the Project Formulation Meeting ''Compilation of Anatomical, Physiological and Metabolic Characteristics for a Reference Asian Man'', the measurement of physique, organ mass and the food consumption were given the first priority for the first phase of the project.

  6. Contribution of inhalation by food animals to man's ingestion dose

    Animals' inhalation (AI) pathway was evaluated for 57 radionuclides using infant dose predictions from the food-chain model LIMCAL. With ingestion transfer coefficients fMi to define transfer from the respiratory tract to milk, the AI pathway appeared to be insignificant compared to animals' plant ingestion, as implicitly assumed in most environmental assessment models for nuclear installations. Using ICRP Publication 30 respiratory clearance models for man to adjust ingestion transfer coefficients, animals' inhalation appeared to be important, particularly for some actinide radionuclides. The AI pathway also appeared to be significant relative to man's inhalation, especially for infants. The importance of the AI pathway varied greatly between radionuclides, and results strongly suggest that it cannot be ignored in environmental assessments. Until better data become available to implement this pathway fully, adjusted ingestion transfer coefficient values can be used for transfer from animals' respiratory tract to milk and other food products

  10. The evolution of man and the extinction of animals

    Remmert, Hermann

    1982-11-01

    Africa has lost only very few big mammals at the end of the pleistocene. Evidence is put forward that the reason for the present richness of the African mammal fauna is a very early coevolution between evolving man and the megafauna of this area. Areas without such an early coevolution suffered severe losses (up to 100%) of their native megafauna, when early hunters invaded them.

  11. Health care delivery system for long duration manned space operations

    Logan, J. S.; Shulman, E. L.; Johnson, P. C.

    1983-01-01

    Specific requirements for medical support of a long-duration manned facility in a low earth orbit derive from inflight medical experience, projected medical scenarios, mission related spacecraft and environmental hazards, health maintenance, and preventive medicine. A sequential buildup of medical capabilities tailored to increasing mission complexity is proposed. The space station health maintenance facility must provide preventive, diagnostic, and therapeutic medical support as immediate rescue capability may not exist.

  15. Graham Greene and Cuba: Our man in Havana?

    Peter Hulme

    2008-12-01

    Full Text Available [First paragraph] Graham Greene’s novel Our Man in Havana was published on October 6, 1958. Seven days later Greene arrived in Havana with Carol Reed to arrange for the filming of the script of the novel, on which they had both been working. Meanwhile, after his defeat of the summer offensive mounted by the Cuban dictator, Fulgencio Batista, in the mountains of eastern Cuba, just south of Bayamo, Fidel Castro had recently taken the military initiative: the day after Greene and Reed’s arrival on the island, Che Guevara reached Las Villas, moving westwards towards Havana. Six weeks later, on January 1, 1959, after Batista had fled the island, Castro and his Cuban Revolution took power. In April 1959 Greene and Reed were back in Havana with a film crew to film Our Man in Havana. The film was released in January 1960. A note at the beginning of the film says that it is “set before the recent revolution.” In terms of timing, Our Man in Havana could therefore hardly be more closely associated with the triumph of the Cuban Revolution. But is that association merely accidental, or does it involve any deeper implications? On the fiftieth anniversary of novel, film, and Revolution, that seems a question worth investigating, not with a view to turning Our Man in Havana into a serious political novel, but rather to exploring the complexities of the genre of comedy thriller and to bringing back into view some of the local contexts which might be less visible now than they were when the novel was published and the film released.

  20. Helper cell-independent cytotoxic clones in man

    1982-01-01

    We report here a class of helper cell-independent cytotoxic T cell (HITc) clones in man that can proliferate in response to antigenic stimulation as well as mediate cytotoxicity. HITc appear to be rare among clones derived from primary in vitro allosensitized culture, but constitute the majority of clones derived from cells sensitized to autologous Epstein-Barr virus-transformed lymphoblastoid cell lines. The implications of the derivation and function of HITc clones are discussed.

Measles vaccines, which are based on attenuated live virus, have been quite effective in control...

  2. Man-machine communication in reactor control using AI methods

    In the last years the interest in process control has expecially focused on problems of man-machine communication. It depends on its great importance to process performance and user acceptance. Advanced computerized operator aids, e.g. in nuclear power plants, are as well as their man-machine interface. In the Central Institute for Nuclear Research in Rossendorf a computerized operator support system for nuclear power plants is designed, which is involved in a decentralized process automation system. A similar but simpler system, the Hierarchical Informational System (HIS) at the Rossendorf Research Reactor, works with a computer controlled man-machine interface, based on menu. In the special case of the disturbance analysis program SAAP-2, which is included in the HIS, the limits of menu techniques are obviously. Therefore it seems to be necessary and with extended hard- and software possible to realize an user controlled natural language interface using Artificial Intelligence (AI) methods. The draft of such a system is described. It should be able to learn during a teaching phase all phrases and their meanings. The system will work on the basis of a self-organizing, associative data structure. It is used to recognize a great amount of words which are used in language analysis. Error recognition and, if possible, correction is done by means of a distance function in the word set. Language analysis should be carried out with a simplified word class controlled functional analysis. With this interface it is supposed to get experience in intelligent man-machine communication to enhance operational safety in future. (author)

    Full Text Available An elderly man, a known case of generalized vitiligo of long duration, presented to us with an ulcerated exophytic growth arising from the vitiliginous skin. The histopathological study confirmed the clinical suspicion of squamous cell carcinoma. Cutaneous neoplasia arising from the vitiliginous skin is a rare situation. Lack of melanin leaves the skin vulnerable to ultraviolet radiation damage, which may predispose to cutaneous neoplasia. Therefore, the importance of photoprotection has been stressed upon through this illustration.

    Ellison's Invisible Man tells the experiences of a young black in search of his cultural identity in American society in the first half of the 20th century. Because of the racial discrimination, tangible or intangible, his efforts were hindered every now and then and he was often baffled, not knowing "who he was". His confusion reflects the serious situation in which the American blacks were involved. His endeavors also suggest the American blacks' dream of establishing themselves in the society.

  16. [Parasitic specificity and development of stray parasites of animal origin in man].

    Euzéby, J

    1994-04-01

    As on introduction to the selected topic, the author, after conjuring up the problem of parasite specificity, describes the various biological behaviour of parasites of animal origin having got into man. So doing, he quotes two main types of parasitic zoonoses (1) holozoonoses, in which the parasites are able to pass from animals to man and back; (2) hemi-zoonoses, in which parasites cannot go back from man to animals. The latter are due: (a) either to the inability for the parasite to reach, in man, the stage which would enable it to follow on its life cycle; this is a biological phenomenon: man is a dead-lock for the parasite; (b) or to the necessity for a parasite having reached a suitable stage in man, to go back-to animal through predation of man by the animal; this is an ethological phenomenon: man is a cul-de-sac for the parasite.

  17. Survival Data and Regression Models

    Grégoire, G.

    2014-12-01

    We start this chapter by introducing some basic elements for the analysis of censored survival data. Then we focus on right censored data and develop two types of regression models. The first one concerns the so-called accelerated failure time models (AFT), which are parametric models where a function of a parameter depends linearly on the covariables. The second one is a semiparametric model, where the covariables enter in a multiplicative form in the expression of the hazard rate function. The main statistical tool for analysing these regression models is the maximum likelihood methodology and, in spite we recall some essential results about the ML theory, we refer to the chapter "Logistic Regression" for a more detailed presentation.

    It's been 16 years since I first took a physics class at Weber State University. Since them, I've survived graduate school in Nuclear Engineering, and a postdoc appointment doing nuclear nonproliferation. Now I'm a Technical Staff Member at Los Alamos National Laboratory working with nuclear data, the physics behind the numerical simulations of nuclear reactors and nuclear weapons. Along the way, I've learned a few things. First, scientific computing is everywhere in science. If you are not writing codes, you will be analyzing their output, and generally there will be more output than a human can correctly and accurately interpret in a timely manner. Second, a career in science or engineering can be very rewarding with opportunities to collaborate with and generate friendships with very bright people from all over the world.

    This final report is a documentation of the activities and work performed by JAYCOR during the period from June 11, 1992 through March 10, 1993 to support Lawrence Livermore National Laboratory (LLNL) in the development of radiation tolerant optical subsystems and components for use under the Advanced Implementation Technology (AIT) effort. The work is primarily directed towards: performance of above-ground testing and analysis of the LLNL space-based LIDAR (Laser Illuminated Detection and Ranging) system and components, and compilation of a radiation effects data base for bulk optical materials, i.e., glasses. The objective is to support LLNL activities in the area of optics survivability and in engineering a radiation hardened LIDAR that can survive and operate through natural, as well as hostile, space environments (primary emphasis is on operation in electron, proton, and total dose environment). An analysis of the LIDAR design as developed by Kigre, Inc. for LLNL shows that the most susceptible components in terms of radiation susceptibility are the doubling crystal and laser rod materials. The radiation susceptibility analysis of the Kigre design (pulsed Q-switch mode) is performed using data obtained from above-ground testing of each individual component material. A passive Q-switch material is evaluated and found to degrade via a decrease in the amount of saturable absorption relative to an un-irradiated sample. Several different doubling crystal types (LBO, KTP, KD*P) are also evaluated for both total dose and high energy proton susceptibility. LBO is the least susceptible and KTP is the most affected by exposure to ionizing radiation. An analysis of the Kigre system response as a function of total dose is made, including the effects on thin film anti-reflection and band-pass filter coatings.

  2. Maternal nutrition, health, and survival.

    The burden of maternal morbidity and mortality in developing countries is high. Each year, 600,000 women die from pregnancy-related causes and 62 million women suffer from morbidity and complications of pregnancy. The extent to which maternal nutrition can improve maternal health and survival is not well understood. Excluding deaths due to induced abortions, the other four main causes of maternal mortality (preeclampsia, hemorrhage, obstructed labor, and infection) may be amenable to nutrition interventions. The role of calcium in reducing the incidence of preeclampsia and hypertension is promising, but more research in deficient populations is urgently needed. Antenatal iron supplementation, although frequently recommended to prevent anemia during pregnancy, has had little program success. Severe anemia may be an important cause of maternal mortality, but convincing evidence is lacking on the health consequences of mild-to-moderate maternal anemia. Knowledge of the etiology of anemia is important in identifying effective strategies for combating it. Other vitamins such as folate, B12, and vitamin A may enhance the effect of iron supplementation in populations where multiple nutrition deficiencies exist. Maternal night blindness is widespread in South Asian women. In Nepal, this condition is associated with markedly increased risks of vitamin A deficiency, anemia, morbidity, and maternal and infant mortality. These findings need to be replicated elsewhere in South Asia. One study has shown vitamin A and beta carotene supplementation to reduce maternal mortality and morbidity. These findings need testing in different settings with emphasis on investigating the mechanisms of the effect. The area of prepregnancy nutrition and its influence on prolonged and obstructed labor is wide open for investigation. The scope for research in the area of maternal nutrition and health is large and the onus is on nutritionists to bring to the forefront the role of nutrition in

  3. Man-machine interface in the nuclear industry

    The International Conference on Man-Machine Interface in the Nuclear industry (Control and Instrumentation, Robotics and Artificial Intelligence), held in Tokyo, Japan, 15-19 February 1988, was organized by the International Atomic Energy Agency in co-operation with the Nuclear Energy Agency of the OECD and the Commission of the European Communities. The 460 participants, representing 28 Member States and four international organizations, reviewed recent developments to improve the man-machine interface and discussed directions for future efforts. The 70 papers presented and a panel discussion on ''Man as a Safety Factor in NPP Operation: His Abilities and Limitations'' addressed the following main areas, which, as a result of the recent nuclear accident at Chernobyl, and also of recent accidents in the chemical industry, have proved to be of utmost importance in ensuring reliable human performance in plant operation. These areas are: review of status and outlook (2 papers); human behavior in plant operation (9 papers); plant personnel training (7 papers); operator support (14 papers); artificial intelligence and accident management (9 papers); process control and human engineering in control rooms (11 papers); robots for nuclear power plant inspection and maintenance (2 papers); human engineering in controls and control rooms (7 papers); transients and accident management (6 papers); robotics (3 papers). A separate abstract was prepared for each of these 70 papers. Refs, figs and tabs

  4. Diagnosis of Massive Pulmonary Embolism in Man by Radioisotope Scanning

    Macroaggregated human-serum albumin particles labelled with either I131 or chromium-51 have been utilized to determine regional blood flow to the lungs in dogs and man. Following intravenous injection, the particles accumulated in the lung, permitting clear delineation of the lung fields by scintillation scanning. In patients with lung abscess, pneumonia, atelectasis, tumours and thromboembolic disease of the lung, there was a decreased accumulation of the radioactivity in the regions of the lungs involved. The technique was found to be clinically useful in the diagnosis of massive pulmonary emboli in man and in the demonstration of vascular occlusion in certain patients with cor pulmonale. Studies in dogs made possible the determination of the rate at which revascularization occurred following experimental pulmonary emboli. Scintillation scanning was carried out at various times after the removal of the experimental emboli. The circulation was restored through the lungs within a period of several weeks after the removal of chronic pulmonary emboli in dogs. Although aggregated human-serum albumin retained its antigenicity in rabbits, guinea pigs and dogs, extensive studies failed to reveal any antigenicity of the particles to man. Because of the rapid metabolism of the macroaggregated albumin particles, the radiation to the patient was well within permissible levels. The use of albumin of high specific activity permitted injections of small chemical quantities; consequently no cardiovascular effects, such as increases in pulmonary artery pressure, changes in electrocardiogram or respiratory rate, were noted.

  5. Interactive animated displayed of man-controlled and autonomous robots

    An interactive computer graphics program has been developed which allows an operator to more readily control robot motions in two distinct modes; viz., man-controlled and autonomous. In man-controlled mode, the robot is guided by a joystick or similar device. As the robot moves, actual joint angle information is measured and supplied to a graphics system which accurately duplicates the robot motion. Obstacles are placed in the actual and animated workspace and the operator is warned of imminent collisions by sight and sound via the graphics system. Operation of the system in man-controlled mode is shown. In autonomous mode, a collision-free path between specified points is obtained by previewing robot motions on the graphics system. Once a satisfactory path is selected, the path characteristics are transmitted to the actual robot and the motion is executed. The telepresence system developed at the University of Florida has been successful in demonstrating that the concept of controlling a robot manipulator with the aid of an interactive computer graphics system is feasible and practical. The clarity of images coupled with real-time interaction and real-time determination of imminent collision with obstacles has resulted in improved operator performance. Furthermore, the ability for an operator to preview and supervise autonomous operations is a significant attribute when operating in a hazardous environment

    1976-01-01

    A program to evaluate the performance of a one man capacity, self contained electrochemical air revitalization system was successfully completed. The technology readiness of this concept was demonstrated by characterizing the performance of this one man system over wide ranges in cabin atmospheric conditions. The electrochemical air revitalization system consists of a water vapor electrolysis module to generate oxygen from water vapor in the cabin air, and an electrochemical depolarized carbon dioxide concentrator module to remove carbon dioxide from the cabin air. A control/monitor instrumentation package that uses the electrochemical depolarized concentrator module power generated to partially offset the water vapor electrolysis module power requirements and various structural fluid routing components are also part of the system. The system was designed to meet the one man metabolic oxygen generation and carbon dioxide removal requirements, thereby controlling cabin partial pressure of oxygen at 22 kN/sq m and cabin pressure of carbon dioxide at 400 N/sq m over a wide range in cabin air relative humidity conditions.

  7. Hormonal profiles behind the heart of a man.

    Sarkar, Narendra Nath

    2009-01-01

    This study focuses on the role of sex steroids on the libido, sexual life, emotional and physiological heart of men of all ages. Sex steroids play a significant role throughout a man's life, with a gradual decline in old age. The foetal testis secretes testosterone and dehydroepiandrosterone at about nine weeks gestation. At puberty, testosterone increases dramatically in boys. Changes in weight and height of boys across this period are associated with increasing testosterone concentration and sex hormone binding globulin (SHBG). Romantic thoughts, fantasy, and sexual pleasure-seeking behaviour in adolescents are associated with exposure to high androgens secretion. Thus, the libido and sexual life of a man is initiated and maintained by testosterone and SHBG. Lower testosterone levels are associated with erectile dysfunction among other risk factors: diabetes, hypertension, heart disease, psychological stress and obesity. Men with proven coronary atherosclerosis have lower levels of testosterone and SHBG, which have negative correlation with very low-density lipoprotein, triglycerides, body mass index and body fat mass. These are some of the risk factors for cardiovascular diseases. Thus, in men, endogenous sex steroids impart beneficial effects on the heart. How exactly endogenous sex steroids act on the heart is not clear. Further study is needed to understand the interaction between endogenous sex steroids, higher centers in the brain and the heart of a man. PMID:19653170

  8. An Assessment of Environmental Health Needs for Manned Spacecraft

    Macatangay, Ariel V.

    2013-01-01

    Environmental health fundamentally addresses the physical, chemical, and biological risks external to the human body that can impact the health of a person by assessing and controlling these risks in order to generate and maintain a health-supportive environment. Environmental monitoring coupled with other measures including active and passive controls and the implementation of environmental standards (SMACs, SWEGs, microbial and acoustics limits) are used to ensure environmental health in manned spacecraft. NASA scientists and engineers consider environmental monitoring a vital component to an environmental health management strategy for maintaining a healthy crew and achieving mission success. Environmental monitoring data confirms the health of ECLS systems, in addition to contributing to the management of the health of human systems. Crew health risks associated with the environment were reviewed by agency experts with the goal of determining risk-based environmental monitoring needs for future NASA manned missions. Once determined, gaps in knowledge and technology, required to address those risks, were identified for various types of Exploration missions. This agency-wide assessment of environmental health needs will help guide the activities/hardware development efforts to close those gaps and advance the knowledge required to meet NASA manned space exploration objectives. Details of this assessment and findings are presented in this paper.

  9. Basic researches for advancement of man-machine systems

    The historical development of plant instrumentation and control system accompanying the introduction of automation is shown by the example of nuclear power plants. It is explained, and the change in the role of operators in the man-machine system is mentioned. Human errors are the serious problem in various fields, and automation resolves it. But complex systems also caused various disasters due to the relation of men and machines. The problem of human factors in high risk system automation is considered as the heightening of reliability and the reduction of burden on workers by decreasing human participation, and the increase of the risk of large accidents due to the lowering of reliability of human elements and the strengthening of the training of workers. Human model and the framework of human error analysis, the development of the system for man-machine system design and information analysis and evaluation, the significance of physiological index measurement and the perspective of the application, the analysis of the behavior of subjects in the abnormality diagnosis experiment using a plant simulator, and the development to the research on mutual adaptation interface are discussed. In this paper, the problem of human factors in system safety, that technical advancement brings about is examined, and the basic research on the advancement of man-machine systems by the author is reported.

  10. Detecting and tracking humans using a man-portable robot

    Baran, David; Fung, Nick; Ho, Sean; Sherman, James

    2009-05-01

    Large gains in the automation of human detection and tracking techniques have been made over the past several years. Several of these techniques have been implemented on larger robotic platforms, in order to increase the situational awareness provided by the platform. Further integration onto a smaller robotic platform that already has obstacle detection and avoidance capabilities would allow these algorithms to be utilized in scenarios that are not plausible for larger platforms, such as entering a building and surveying a room for human occupation with limited operator intervention. However, transitioning these algorithms to a man-portable robot imparts several unique constraints, including limited power availability, size and weight restrictions, and limited processor ability. Many imaging sensors, processing hardware, and algorithms fail to adequately address one or more of these constraints. In this paper, we describe the design of a payload suitable for our chosen man-portable robot, the iRobot Packbot. While the described payload was built for a Packbot, it was carefully designed in order to be platform agnostic, so that it can be used on any man-portable robot. Implementations of several existing motion and face detection algorithms that have been chosen for testing on this payload are also discussed in some detail.

  11. Man made global warming explained - closing the blinds

    Sloan, T

    2010-01-01

    One of the big problems of the age concerns 'Global Warming', and whether it is 'man-made' or 'natural'. Most climatologists believe that it is very likely to be the former but some scientists (mostly non-climatologists) subscribe to the latter. Unsurprisingly, the population at large is often confused and and is not convinced either way. Here we try to explain the principles of man-made global warming in a simple way. Our purpose is to try to understand the story which the climatologists are telling us through their rather complicated general circulation models. Although the effects in detail are best left to the climatologists' models, we show that for the Globe as a whole the effects of man-made global warming can be demonstrated in a simple way. The simple model of only the direct heating from the absorption of infrared radiation, illustrates the main principles of the science involved. The predicted temperature increase due to the increase of greenhouse gases in the atmosphere over the last century descr...

  12. Kinetics of lactate turnover and oxidation in man

    The turnover and oxidation of lactic acid have been studied in man by means of 14C-lactic acid, 14C-glucose, and 14C-alanine. The use of these labels in separate studies has enabled us to describe a complete scheme for the kinetics of lactic acid in man. We have determined that lactate arises from a minimum of two sources in overnight fasted man. 66% of lactate at this time arises from the metabolism of glucose while approximately 15% is derived from alanine. These sources and others unidentified supply lactate to the body pool at a rate of approximately 95 mg per kg per h. The disposal of this quantity of lactate is achieved through a minimum of three routes. Approximately 57% of the lactate turnover is oxidized to carbon dioxide, 15% is reduced to glucose, and approximately 25% is converted to alanine. The quantitative changes in the kinetics of this system that are brought on by fasting add an interesting dimension to the system. In agreement with the concepts of fuel economy in fasting the contribution of glucose carbon to lactic acid falls and, in turn, the contribution of lactate carbon to body glucose rises. The study of additional permutations of this system suggest that lactate, with pyruvate, is in the main stream of the intermediary metabolism of the body. The authors suggest that the study of this system offers promise of a fuller understanding of the derangements of metabolic disease. (author)

    2011-01-01

    In his still today indispensable The Fall of Natural Man, Anthony Pagden drew a distinction between a natural man ‘living outside human society’, as understood in the sixteenth century by those scholastic theologians and humanist rhetoricians he was concerned with, and the Enlightenment (or Rousseauian) view of natural man as a man stripped of the artificial trappings of civilization. If the history of the European intellectual encounter with the American Indian could be construed as the “fal...

  16. Assessment of Radioactivity in Man. Vol. I. Proceedings of the Symposium on the Assessment of Radioactive Body Burdens in Man

    This Symposium on the Assessment of Radioactive Body Burdens in Man was organized jointly by the International Atomic Energy Agency, the International Labour Organisation and the World Health Organization and was held in Heidelberg from 11-15 May 1964. It was attended by 181 participants from 28 countries and 6 international organizations. It was the objective of the Symposium to bring together experts from the various scientific disciplines of physics, chemistry, biology, medicine and mathematics, and to survey their experience in the assessment of radioactive body burdens in man and the resultant radiation doses. In most investigations of internal contamination the errors in the physical measurements are smaller than the errors associated with the interpretation of measurements. For this reason special emphasis was laid in this meeting on the interpretation of measured data. The 67 papers and the discussions which they stimulated are published in these Proceedings produced in two volumes. Volume I includes all papers which deal with problems generally common to many isotopes: in- vivo counting, bioassay techniques, sample counting and analysis of data. Volume II includes those papers concerned with radioisotopes of specific elements: caesium, radium, radon, strontium, tritium, thorium, uranium, plutonium and rare earth elements. These Proceedings should prove invaluable to all radiation protection services entrusted with the physical surveillance of internal radiation exposure of man. They should complement the studies of the International Commission on Radiological Protection (ICRP) and assist the work of the Organizations that jointly organized the meeting

  17. Natural and radiation-induced cataracts in man and mouse, and natural macular degeneration in man: proposed mechanisms

    A unified theory of growth and age-dependent disorders is applied to the interpretation of epidemiological data for natural and radiation-induced cataracts and natural macular degeneration in man. Using the same unified theory, mechanisms are also proposed to explain the experimental evidence for natural and radiation-induced lenticular opacities in the lens of the mouse. Epidemiological and experimental data are strikingly consistent with the hypothesis that natural cataract formation is an autoaggressive process but the details of pathogenesis differ greatly between the two species. Radiation dose-response relations reflect these contrasts.. Lenticular opacities in the nuclear-bomb survivors at Hiroshima and Nagasaki were probably induced by a 'single-track' mechanism. Radiation-induced generalised opacification in the lens of the mouse results from a 'multi-track' process. The pathogenesis of natural macular degeneration in man happens to have close parallels with that of natural opacification in the mouse. Some implications of these inferences for the phenomenon of radiation-induced lethal disorders in man are discussed. (author)

  18. The monetary value of the man.rem and optimization in radiation therapy (brachytherapy)

    The personnel exposed by sources used for intracavitary radiation therapy in Denmark receive more than 40% of the collective dose recorded by personal dosemeters in Denmark. As the application of after-loading technique has become generally accepted by the medical profession in Denmark as a replacement to a considerable degree for manual radium therapy, the most promising suggestion for reduction of radiation doses is the introduction of after-loading facilities in all radiation therapy centres. Such facilities are now being planned in Denmark but their realization will entail great expense and therefore the financial aspects of these plans will be very important. At present the advantage of after-loading cannot be simply demonstrated to the politicians holding the purse strings, i.e. in terms of improved therapeutical gain, e.g. increased survival, although the incidence of complications has been shown to be lower, but the reduction in personnel radiation doses by the change to after-loading will be evident and be an important part of the cost-benefit analysis. By detailed investigation of all expenditures and savings, cost-benefit analysis has been carried out in order to isolate the relationship between expense and the collective dose reduction. If after-loading facilities are established in Denmark today with the intention of reducing the risk for employees and without any expectation of improvements in treatment, the monetary value of the man.rem implied is 10,000 kr. or 2000 US dollars.

  19. [Population biology of cestode genus Triaenophorus in natural and man-made water bodies].

    Ieshko, E P; Anikieva, L V; Lebedeva, D I; Il'mast, N V

    2012-01-01

    A comparative study of the frequencies of occurrence and distribution of the abundances of pike parasites, tapeworms of the genus Triaenophorus, was carried out in natural lakes and water bodies contaminated by the Kostomuksha mining and concentration mill (Northern Karelia). We demonstrate that the wide presence of T. crassus and T. nodulosus in natural northern lakes is due to the diversity of aquatic organisms and the structure of trophic relations. The abundance of both species is modeled by the negative binomial distribution. Relations in the host-parasite system are stable. Estimates of the parameter k of the negative binomial distribution reflect the changes in the interactions in the host-parasite system. T. nodulosus has survived in the man-made water body storing the highly mineralized recirculated water from the mill. Disturbance-related distinctions were detected in the parameters of the T. nodulosus abundance distribution in the host population. In the Okunevoye Lake, where the water discharged from the tailings dump is more diluted, the infection rates in pike did not differ from those in undisturbed water bodies. PMID:23458019

  20. Survival post surgery for malignant pericardial effusion

    Olivier Nguyen

    2011-05-01

    Full Text Available The study reviews the survival of patients with malignant pericardial effusion treated with a subxiphoid pericardial window. The medical records of 60 consecutive patients diagnosed with a malignant pericardial effusion and treated with a subxiphoid pericardial window between 1994 and 2008 were reviewed. 72% had lung cancer. Overall 30-day mortality was 31%. Survival rates at 3 months, 6 months, 1 year, and 2 years were 45%, 28%, 17%, and 9%, respectively. Overall median survival was 2.6 months. Patients with malignant pericardial effusion, especially those with primary lung cancer have poor survival rates. In advanced malignancy, the subxiphoid pericardial window procedure provides only short-term palliation of symptoms, and has no effect on long-term survival. The use of any surgical procedure in patients with malignant advanced pericardial effusion should be considered along with nonsurgical options on a case-by-case basis depending on symptoms, general status, and expected survival.

    Theory predicts a number of mechanisms through which survival expectations influence retirement decisions: a wealth effect of a longer lifespan; an uncertainty effect through the return on savings; a longevity risk effect; and, an adverse selection effect from pooling within pensions. We use data from the first three waves of the English Longitudinal Study of Ageing to test whether the timing of retirement is responsive to subjective survival expectations.

    Survival for mesothelioma has been shown to be poor, with marginal improvement over time. Recent advances in the understanding of pathophysiology and treatment of mesothelioma may impact therapy to improve survival that may not be evident from available clinical trials that are often small and not randomized.

  10. Survival Strategies: LCTLs in Context

    Marilyn S. Manley

    2008-01-01

    Full Text Available This paper explores an example of successful curriculum de-velopment and methodology for the study of the Quechua language at the university level. This recipe for success falls in line with rec-ommendations made by the MLA Ad Hoc Committee on Foreign Languages, as expressed in their May 2007 report, “Foreign Lan-guages and Higher Education: New Structures for a Changed World”, and may be applied to the case of other LCTLs. This paper argues that, while the MLA’s report was intended for a general audi-ence of foreign language educators, its recommendations are especial-ly vital to the study of the less commonly taught languages. Among the many recommendations included in the report, two in particular stand out as being most essential to the survival of the LCTLs. These are an increase in interdisciplinary courses and inter-departmental alliances as well as a greater integration of cultural study in foreign language teaching.

  11. Improving Survival in Decompensated Cirrhosis

    Amar Nath Mukerji

    2012-01-01

    Full Text Available Mortality in cirrhosis is consequent of decompensation, only treatment being timely liver transplantation. Organ allocation is prioritized for the sickest patients based on Model for End Stage Liver Disease (MELD score. In order to improve survival in patients with high MELD score it is imperative to preserve them in suitable condition till transplantation. Here we examine means to prolong life in high MELD score patients till a suitable liver is available. We specially emphasize protection of airways by avoidance of sedatives, avoidance of Bilevel Positive Airway Pressure, elective intubation in grade III or higher encephalopathy, maintaining a low threshold for intubation with lesser grades of encephalopathy when undergoing upper endoscopy or colonoscopy as pre transplant evaluation or transferring patient to a transplant center. Consider post-pyloric tube feeding in encephalopathy to maintain muscle mass and minimize risk of aspiration. In non intubated and well controlled encephalopathy, frequent physical mobility by active and passive exercises are recommended. When renal replacement therapy is needed, night-time Continuous Veno-Venous Hemodialysis may be useful in keeping the daytime free for mobility. Sparing and judicious use of steroids needs to be borne in mind in treatment of ARDS and acute hepatitis from alcohol or autoimmune process.

  12. UV survival of human mycoplasmas

    The inactivation by ultraviolet (UV) light irradiation of mycoplasma cells of five human strains was monitored by investigating the colony-forming ability. The survival curves of five strains tested indicated that the cells of Mycoplasma buccale only are single and homogenously susceptible to UV light. The effect of the repair inhibitor, caffeine, on the colony-forming ability of UV-irradiated cells was investigated with M. buccale because of its homogeneous susceptibility to UV light. The colony formation of irradiated cells was markedly depressed by post-irradiation treatment with caffeine at concentration that had little or no effect on the colony formation of unirradiated cells. The colony-forming units (CFU) of UV-irradiated cells which were kept in broth without caffeine in the dark increased without a lag as the time in the dark increased. The colony-forming ability of the irradiated cells completely recovered after 3 hr in the dark. However, when irradiated cells were kept in the presence of caffeine, no increase in their CFU was observed. The mode of action of caffeine on UV-irradiated cells closely resembles that described for other organisms which possess dark reactivation systems for UV-induced damage in deoxyribonucleic acid. Thus, the results obtained provide evidence for the existence of a dark repair function in M. buccale. (author)

  13. Multivariate piecewise exponential survival modeling.

    Li, Yan; Panagiotou, Orestis A; Black, Amanda; Liao, Dandan; Wacholder, Sholom

    2016-06-01

    In this article, we develop a piecewise Poisson regression method to analyze survival data from complex sample surveys involving cluster-correlated, differential selection probabilities, and longitudinal responses, to conveniently draw inference on absolute risks in time intervals that are prespecified by investigators. Extensive simulations evaluate the developed methods with extensions to multiple covariates under various complex sample designs, including stratified sampling, sampling with selection probability proportional to a measure of size (PPS), and a multi-stage cluster sampling. We applied our methods to a study of mortality in men diagnosed with prostate cancer in the Prostate, Lung, Colorectal, and Ovarian (PLCO) cancer screening trial to investigate whether a biomarker available from biospecimens collected near time of diagnosis stratifies subsequent risk of death. Poisson regression coefficients and absolute risks of mortality (and the corresponding 95% confidence intervals) for prespecified age intervals by biomarker levels are estimated. We conclude with a brief discussion of the motivation, methods, and findings of the study. PMID:26583951

  14. Adrenergic Modulation of Pancreatic Glucagon Secretion in Man

    Gerich, John E.; Langlois, Maurice; Noacco, Claudio; Schneider, Victor; Forsham, Peter H.

    1974-01-01

    In order to characterize the influence of the adrenergic system on pancreatic glucagon secretion in man, changes in basal glucagon secretion during infusions of pure alpha and beta adrenergic agonists and their specific antagonists were studied. During infusion of isoproterenol (3 μg/min), a beta adrenergic agonist, plasma glucagon rose from a mean (±SE) basal level of 104±10 to 171±15 pg/ml, P < 0.0002. Concomitant infusion of propranolol (80 μg/min), a beta adrenergic antagonist, prevented the effects of isoproterenol, although propranolol itself had no effect on basal glucagon secretion. During infusion of methoxamine (0.5 mg/min), an alpha adrenergic agonist, plasma glucagon declined from a mean basal level of 122±15 to 75±17 pg/ml, P < 0.001. Infusion of phentolamine (0.5 mg/min), an alpha adrenergic antagonist, caused a rise in plasma glucagon from a mean basal level of 118±16 to 175±21 pg/ml, P < 0.0001. Concomitant infusion of methoxamine with phentolamine caused a reversal of the effects of phentolamine. The present studies thus confirm that catecholamines affect glucagon secretion in man and demonstrate that the pancreatic alpha cell possesses both alpha and beta adrenergic receptors. Beta adrenergic stimulation augments basal glucagon secretion, while alpha adrenergic stimulation diminishes basal glucagon secretion. Furthermore, since infusion of phentolamine, an alpha adrenergic antagonist, resulted in an elevation of basal plasma glucagon levels, there appears to be an inhibitory alpha adrenergic tone governing basal glucagon secretion. The above findings suggest that catecholamines may influence glucose homeostasis in man through their effects on both pancreatic alpha and beta cell function. Images PMID:4825234

  15. BurnMan: A lower mantle mineral physics toolkit

    Cottaar, Sanne

    2014-04-01

    We present BurnMan, an open-source mineral physics toolbox to determine elastic properties for specified compositions in the lower mantle by solving an Equation of State (EoS). The toolbox, written in Python, can be used to evaluate seismic velocities of new mineral physics data or geodynamic models, and as the forward model in inversions for mantle composition. The user can define the composition from a list of minerals provided for the lower mantle or easily include their own. BurnMan provides choices in methodology, both for the EoS and for the multiphase averaging scheme. The results can be visually or quantitatively compared to observed seismic models. Example user scripts show how to go through these steps. This paper includes several examples realized with BurnMan: First, we benchmark the computations to check for correctness. Second, we exemplify two pitfalls in EoS modeling: using a different EoS than the one used to derive the mineral physical parameters or using an incorrect averaging scheme. Both pitfalls have led to incorrect conclusions on lower mantle composition and temperature in the literature. We further illustrate that fitting elastic velocities separately or jointly leads to different Mg/Si ratios for the lower mantle. However, we find that, within mineral physical uncertainties, a pyrolitic composition can match PREM very well. Finally, we find that uncertainties on specific input parameters result in a considerable amount of variation in both magnitude and gradient of the seismic velocities. © 2014.

  18. [The Six Million Dollar Man: from fiction to reality].

    Langeveld, C H Kees

    2013-01-01

    The term 'bionic' has been in existence since 1958, but only gained general recognition from the television series 'The Six Million Dollar Man'. Following a crash, the central figure in this series - test pilot Steve Austin - has an eye, an arm and both legs replaced by prostheses which make him stronger and faster than a normal person. This story is based on the science fiction book 'Cyborg' by Martin Caidin. In the world of comic books and films there are a number of examples of people who are given superhuman powers by having technological gadgets built in. Although the latter is not yet possible, the bionic human has now become reality. PMID:24382050

  19. Simulation of Dive Motion of a Deep Manned Submersible

    MALing; CUIWei-cheng

    2004-01-01

    In order to predict the dive motion of a deep manned submersible currently developed in China,a three-degree-of-freedom dynamic model is developed to simulate its dive motion restricted in the vertical plane. Being the nonlinear function of attack angle, the hydrodynamic forces acting upon the submersible are determined by a towing tank test.Based on these experimental values,the hydrodynamic forces are identified by a general regression neural network (GRNN) over a wide range of attack angles.Results of numerical examples are presented in this paper to explain practical applications of the method.

  20. Space and man. [planetary exploration and energy sources

    Kolman, E.

    1974-01-01

    The effects of man's entry into space on changes in economics and technology, politics and law, science, philosophy, and art are considered. A single world economy, extracting from the natural resources of the moon and other cosmic bodies raw materials and energy, will avoid terrestrial limitations and improve society by eliminating the inequalities of economic and social status. However, a spacecraft for interplanetary travel require thermonuclear engines that achieve an escape velocity of 0.1 times the speed of light in order to allow an astronaut stellar expedition corresponding to the active life of a single generation.

  2. Odontoid fracture following a fall in an elderly man.

    Pagnez, Maria Alice Mainenti; Elliott, James M

    2011-12-01

    The patient was a 79-year-old man with a chief complaint of neck pain after a fall. Three days following the fall, the patient was seen in the emergency department, where computed tomography imaging of the head and radiographs of the cervical spine were completed. The patient was subsequently referred to a physical therapist. Due to concern for a possible undetected cervical spine fracture, the patient was immediately referred to his physician. Magnetic resonance imaging demonstrated a type II fracture of the odontoid. PMID:22146556

  3. Man-boy lovers: assessment, counseling, and psychotherapy.

    van Naerssen, A

    1990-01-01

    Clinical experiences with 36 males, between the ages of 21 and 60 are described. All of them felt an enduring sexual attraction for boys. Sixteen males were treated for sexual identity conflicts. For eight of them this ended in a positive self-labeling as pedophile, the others had severe problems with accepting sexuality as positive and lustful. Twenty males were treated for identity management problems and counseled how to handle their relationships with boys. Several modalities of interpersonal interaction in man-boy relationships are proposed and the ways conflicts can arise within these frames of reference are explored in counseling and psychotherapy.

  12. Dose limits for man do not adequately protect the ecosystem

    As has been noted by both of our participants, it is interesting to see that their views approached agreement during the course of the debate. This is not altogether unexpected since the topic is one that has many facets. It is fair to say that protecting man is an appropriate starting point for the protection of other more, or less, radiosensitive life forms sharing the planet with us. That there may be special situations requiring attention has been recognized by both of our participants. That the ICRP recognizes the need for further work on this topic is encouraging for ourselves as well as the 'bugs and bunnies'. (authors)

  13. Examination of the pathways from soil to man for plutonium

    1977-04-01

    The data available on resuspension and ingestion as pathways of plutonium from soil to man were reviewed and a recommended limit based upon a conservative interpretation of the National Council on Radiation Protection and Measurements (NCRP) recommendations for limiting values was derived. Wind resuspension appeared to be the least limiting value with mechanical resuspension and pica in children among the more important. Ingestion of foodstuffs could also be an important pathway if it is assumed that all food is produced in the contaminated area.

    We report a case of bronchopulmonary sequestration (BPS) in a 60 year old man with recurrent cough. After failed antibiotic therapy for presumed left lower lobe (LLL) pneumonia seen on chest radiographs, bronchoscopy was performed revealing cryptogenic organizing pneumonia. Further work-up with thoracic imaging demonstrates a feeding artery from the thoracic aorta to the LLL consolidation indicating the presence of BPS. A brief review of the clinical and radiological features and management options of BPS are listed, with particular emphasis on the various imaging modalities and techniques in the diagnosis and pre-surgical planning of intralobar sequestration.

    Infective endocarditis caused by zoonotic microorganisms is an uncommon clinical entity. A 55-year-old man was diagnosed with endocarditis due to Capnocytophaga canimorsus, a commensal bacterium contained in the saliva of dogs, that involved the aortic and tricuspid valves and was complicated by a para-aortic valve abscess and aorta-to-right atrial fistula. The patient was successfully treated with antibiotic therapy and surgical intervention. C canimorsus endocarditis should be considered in patients with culture-negative endocarditis, particularly in immunosuppressed, asplenic or alcoholic individuals who have recently suffered a dog bite or have had close contact with dogs.

    The assembly and evaluation of large space platforms in low earth orbit will become practical in the Shuttle era. Extravehicular crewmembers, equipped with manned maneuvering units (MMUs), will play a vital role in the construction and checkout of these platforms. The MMU is a propulsive backpack with mobility extending the crew's visual, mental, and manipulative capabilities beyond the cabin to on-the-spot assembly and maintenance operations. Previous MMU experience is reviewed, Shuttle MMU design features related to space platform support are described, and the use of the MMU for specific construction and assembly tasks is illustrated.

    Leprosy (Hansen's disease) is a chronic contagious granulomatous disease principally affecting the skin and peripheral nervous system, caused by Mycobacterium leprae. In this report, we present a case of autochthonous leprosy in a man from Florida as the first human case reported from this region. Authors believe dermatologists need to be aware of the possibility of autochthonous transmission of leprosy in the Eastern-Southern United States, and should consider leprosy in any patient with atypical skin lesions, even when a history of contact with armadillo is missing.

  1. Assumed genetic effects of low level irradiation on man

    The significance of human genetic pathology is stated and a study is made of the assumed effect of low level ionizing radiations. The theoretical notions thus derived are compared to experimental data which are poor. A quick survey of the literature shows that is has not yet been possible to establish a direct relationship between an increase of exposure and any genetic effect on man. However, this must not lead to conclude on the innoxiousness of radiation but rather shows how such analyses are difficult in as much as the effect investigated is necessarily low

  2. A simple breath test for fat malabsorption in man

    The metabolic pathway of 14C-labeled oleic acid leads to the formation and the breath excretion of 14CO2. This behavior can be used for measuring lipid absorption. The simple, accurate screening test includes the ingestion of 14C-labeled triolein and the intermittent collection of breath 14CO2 in a trapping solution. The results are strongly correlated to the measurement of fecal fat. The use of carbon-14 in man should not be restricted, provided the labeled substrates are converted into rapidly excreted metabolites

    Following a review of the knowledge on the assessment of chemical carcinogens, a comparison between chemical and radiological detriments is attempted from a methodological standpoint. The main problem in chemical carcinogenesis is to get proofs, the discussion bearing on the identity of the interspecific biological mechanisms on account of the nearly constant lack of epidemiological data. The quantification of the neoplastic effects of chemical agents has not been fully developed and can be considered case by case only by carrying out a critical examination of the indicators available in order to extrapolate to man or to low doses

    Williamsen, Joel; Evans, Hilary; Bohl, Bill; Evans, Steven; Parker, Nelson (Technical Monitor)

    2001-01-01

    The increase of the orbital debris environment in low-earth orbit has prompted NASA to develop analytical tools for quantifying and lowering the likelihood of crew loss following orbital debris penetration of the International Space Station (ISS). NASA uses the Manned Spacecraft and Crew Survivability (MSCSurv) computer program to simulate the events that may cause crew loss following orbital debris penetration of ISS manned modules, including: (1) critical cracking (explosive decompression) of the module; (2) critical external equipment penetration (such as hydrazine and high pressure tanks); (3) critical internal system penetration (guidance, control, and other vital components); (4) hazardous payload penetration (furnaces, pressure bottles, and toxic substances); (5) crew injury (from fragments, overpressure, light flash, and temperature rise); (6) hypoxia from loss of cabin pressure; and (7) thrust from module hole causing high angular velocity (occurring only when key Guidance, Navigation, and Control (GN&C) equipment is damaged) and, thus, preventing safe escape vehicle (EV) departure. MSCSurv is also capable of quantifying the 'end effects' of orbital debris penetration, such as the likelihood of crew escape, the probability of each module depressurizing, and late loss of station control. By quantifying these effects (and their associated uncertainties), NASA is able to improve the likelihood of crew survivability following orbital debris penetration due to improved crew operations and internal designs.

  10. Behavioural perspectives on piglet survival.

    Fraser, D

    1990-01-01

    Litters of domestic piglets show strong sibling competition, large differences among litter-mates in birth weight and rate of growth, and, in the absence of human intervention, a high mortality rate. This combination of traits suggests that pigs are using a reproductive strategy similar to that of certain bird species which produce one or more small 'spare' young whose death or survival is determined by sibling competition. Death through competition is natural in such species. Prevention of death requires the early identification and separate rearing of unsuccessful competitors. The major behavioural pathways leading to piglet deaths are considered to be malnutrition through unsuccessful suckling behaviour, and crushing of piglets by the sow. Crushing involves two distinct behavioural sequences: posterior crushing (beneath the sow's hind quarters) and ventral crushing (beneath the udder and rib cage). Farrowing crates are designed to prevent posterior but not ventral crushing. Malnourished piglets appear to be more vulnerable to crushing, perhaps because persistent suckling attempts cause them to spend more time near the sow. Prevention of crushing thus requires a reduction in malnutrition, not merely restriction of the sow's movements. Under certain conditions, dehydration may be an important but neglected aspect of malnutrition. Some litters of piglets have much higher death losses than others, presumably because of risk factors that apply to the litter as a whole. Early malnutrition, resulting from hypogalactia in the sow in the first days after farrowing, appears to be an important risk factor. Farrowing difficulties leading to piglet hypoxia during the birth process may be another. Risk factors that affect whole litters deserve greater emphasis in future research. PMID:2192051

  11. Genes involved in yeast survival after irradiation with fast neutrons

    Life on the Earth has evolved against a continuous background of ionizing radiation. It would be expected, therefore, that all possible mutations have been produced at some time or another; man-made radiation from medical or industrial sources will not result in any new types of mutation but will simply increase the whole spectrum of mutations that occur spontaneously. Any such lesion can be mutagenic and, in principle, lethal. To counteract the consequences of DNA damage, evolution has equipped all living cells with an intricate network of defense and repair systems. Together, these systems act as a kind of nuclear 'immune system' that is able to recognize and eliminate many types of DNA lesions. In the case of the yeast Saccharomyces cerevisiae, in these processes over 30 RAD genes participate. We tested the survival of haploid and diploid rad1 yeast mutant strains at a dose of 15 Gy of γ or fast neutron radiation. We demonstrated that the lethality of rad1 mutants both haploid and diploid are significantly higher after fast neutron irradiation. The results indicate to the role and position of these genes in the DNA repair of damages specifically induced by fast neutrons. (authors)

    2009-07-01

    Full Text Available Abstract Background Examining geographic variation in cancer patient survival can help identify important prognostic factors that are linked by geography and generate hypotheses about the underlying causes of survival disparities. In this study, we apply a recently developed spatial scan statistic method, designed for time-to-event data, to determine whether colorectal cancer (CRC patient survival varies by place of residence after adjusting survival times for several prognostic factors. Methods Using data from a population-based, statewide cancer registry, we examined a cohort of 25,040 men and women from New Jersey who were newly diagnosed with local or regional stage colorectal cancer from 1996 through 2003 and followed to the end of 2006. Survival times were adjusted for significant prognostic factors (sex, age, stage at diagnosis, race/ethnicity and census tract socioeconomic deprivation and evaluated using a spatial scan statistic to identify places where CRC survival was significantly longer or shorter than the statewide experience. Results Age, sex and stage adjusted survival times revealed several areas in the northern part of the state where CRC survival was significantly different than expected. The shortest and longest survival areas had an adjusted 5-year survival rate of 73.1% (95% CI 71.5, 74.9 and 88.3% (95% CI 85.4, 91.3 respectively, compared with the state average of 80.0% (95% CI 79.4, 80.5. Analysis of survival times adjusted for age, sex and stage as well as race/ethnicity and area socioeconomic deprivation attenuated the risk of death from CRC in several areas, but survival disparities persisted. Conclusion The results suggest that in areas where additional adjustments for race/ethnicity and area socioeconomic deprivation changed the geographic survival patterns and reduced the risk of death from CRC, the adjustment factors may be contributing causes of the disparities. Further studies should focus on specific and

  15. Survival of Actinobacillus pleuropneumoniae outside the pig.

    Assavacheep, P; Rycroft, A N

    2013-02-01

    Transmission of Actinobacillus pleuropneumoniae is primarily thought to be via direct transfer of mucus from pig to pig. For transfer between farms, the organism may need to persist in the wet or dried state to be carried on an inanimate surface. The survival of A. pleuropneumoniae was investigated under controlled laboratory conditions. In aqueous suspension, survival was improved by the presence of NaCl and mucin; it was prolonged at lower temperature. In dry state, it survived best on a hydrophobic surface either under desiccated conditions or saturated humidity. Detectable viability was maintained for 3-4 days. When frozen, A. pleuropneumoniae survived for more than 17 weeks at -20 °C, but the viability declined to 0.01% during that time. Survival at -70 °C was effective for long term storage. Results obtained from this investigation would be applicable for sampling method, transport techniques, epidemiological study, and biosecurity implementation. PMID:22892250

    To determine whether 2 readily available indicators predicted survival among patients with Ebola virus disease in Sierra Leone, we evaluated information for 216 of the 227 patients in Bo District during a 4-month period. The indicators were time from symptom onset to healthcare facility admission and quantitative real-time reverse transcription PCR cycle threshold (Ct), a surrogate for viral load, in first Ebola virus–positive blood sample tested. Of these patients, 151 were alive when detected and had reported healthcare facility admission dates and Ct values available. Time from symptom onset to healthcare facility admission was not associated with survival, but viral load in the first Ebola virus–positive blood sample was inversely associated with survival: 52 (87%) of 60 patients with a Ct of >24 survived and 20 (22%) of 91 with a Ct of <24 survived. Ct values may be useful for clinicians making treatment decisions or managing patient or family expectations. PMID:26812579

  17. Does biological relatedness affect child survival?

    2003-05-01

    Full Text Available Objective: We studied child survival in Rakai, Uganda where many children are fostered out or orphaned. Methods: Biological relatedness is measured as the average of the Wright's coefficients between each household member and the child. Instrumental variables for fostering include proportion of adult males in household, age and gender of household head. Control variables include SES, religion, polygyny, household size, child age, child birth size, and child HIV status. Results: Presence of both parents in the household increased the odds of survival by 28%. After controlling for the endogeneity of child placement decisions in a multivariate model we found that lower biological relatedness of a child was associated with statistically significant reductions in child survival. The effects of biological relatedness on child survival tend to be stronger for both HIV- and HIV+ children of HIV+ mothers. Conclusions: Reductions in the numbers of close relatives caring for children of HIV+ mothers reduce child survival.
