    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

    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

    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.

    1983-06-01

    As part of a study for the Nuclear Regulatory Commission (NRC), the Pacific Northwest Laboratory (PNL) is investigating long-term stabilization techniques for uranium mill impoundments. Part of this investigation involves the design of a rock armoring blanket (riprap) to mitigate wind and water erosion of the underlying soil cover, which in turn prevents exposure of the tailings to the environment. However, the need for the armoring blanket, as well as the blanket's effectiveness, depends on the stability of the underlying soil cap (radon suppression cover) and on the tailings themselves. Compelling evidence in archaeological records suggests that large man-made earthen structures can remain sound and intact for time periods comparable to those required for the stabilization of the tailings piles if properly constructed. We present archaeological evidence on the existence and survivability of man-made earthen and rock structures through specific examples of such structures from around the world. We also review factors contributing to their survival or destruction and address the influence of climate, building materials, and construction techniques on survivability.

    2015-11-01

    Full Text Available Two independent experiments were performed to determine the effects of salinity on survival and growth of juvenile Macrobrachium rosenbergii, first one was to determine the median lethal salinity (MLS-5096 h and second one was to assess the survival and growth at different sub-lethal salinities under field condition. In MLS-5096 h study 0, 5, 10, 15, 20, 25 and 30 ppt salinities were used to initially find out the salinity tolerance range. Accordingly, a definitive salinity tolerance test was done in next phase to find out exact median lethal salinity by directly transferring the test species to 21, 22, 23, 24, 25, 26 and 27 ppt salinity for 96 h. The median lethal salinity of M. rosenbergii was estimated at 24.6 ppt. In the second experiment, survival and growth performances of the prawn were recorded at different sub-lethal salinities viz., 5, 10, 15 and 20 ppt along with 0 ppt as control during 60 days culture period. The prawn exhibited lowest final average weight at 20 ppt salinity and significantly highest at 10 ppt salinity. Highest SGR and weight gain were obtained at 10 ppt followed by 5 ppt, 15 ppt and 0 ppt salinity but differences among treatment were not significant (P > 0.05. Survival rate of prawn varied between 91% (at 0 ppt and 78% (at 20 ppt. The prawn grew and survived satisfactorily at 0–15 ppt salinities, implying that the species can be cultured commercially at wide salinity range. M. rosenbergii can be considered as an ideal species to promote, in view of current and future climate variables as more and more coastal areas of India are going to be vulnerable to saline water inundation.

    The efficiency of probiotics (Ecomarine) in rearing of Macrobrachium rosenbergii larvae was evaluated in a commercial prawn hatchery for five weeks. Stage-1 (zero age) larvae (of length: 2 mm; weight: 0.12 mg) were stocked at the rate of 100 L(-1). The experiment determined the growth rate, survival rate of the larvae for the both treatment and control groups. Final average weight were found 8.39 ± 3.28E-04 and 8.18 ± 2.86E-04 mg and length were found 9.08 ± 0.649 and 9.02 ± 0.081 mm for treatment and control group respectively. Comparatively higher growth performance was observed in treatment than control. Post Larvae (PL) was first observed 20th days of culture in treatment tanks whereas PL in control tanks was found 24th days of culture. Survival rate was found 58 and 46% in treatment and control group respectively. There was significant (p < 0.05) survival rate between two experiment groups. This study revealed that probiotics could be better in quality seed production of M. rosenbergii while significant changes were not noticed in the physic-chemical parameters i.e., water temperature, salinity, DO, pH, nitrate-NO2, hardness and alkalinity observed in both the treatments.

    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.

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.

    Science.gov (United States)

    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

    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.

    Full Text Available This experiment aims to study the effect of different levels of salinity (5, 15 and 25 ppt using artificial sea water on the embryonic development and hatching percentage of the eggs of unripe berried female giant freshwater prawns (Macrobrachium rosenbergii with an average size of 14.3+0.6 cm TL. After incubation through the heart beating stage (grayish black eggs, the brooders in each salinity were separately transferred to the hatching tank with 15 ppt saline water for the second part of the study. After hatching, the healthy larvae from the brooders which were previously incubated in 3 levels of salinity were collected for the larviculture experiment. The closed recirculating water system with trickling filter unit packed with fiberglass and bioballs was used as incubation and larviculture units. The metamorphosis period and survival rate were examined. The rearing water from each larviculture aquarium was collected for determination of sodium, magnesium, potassium, calcium and chloride ions. The result showed that the percentage of ripe berried females (with heart beating stage embryos were not significantly different (p>0.05 between 5 and 15 ppt salinity but their values were significantly higher (p0.05 in the survival rate of post larvae and metamorphosis period among the treatments. The first post larvae stage occurred on the 26th day. During 30 days of larviculture, the survival rate of all treatments was 100% until the 19th day, after which it suddenly decreased. When the concentrations of the ions in the rearing water were determined in all treatments, it was found that the concentration of magnesium ions rapidly declined (p0.05. The low survival rate during the final stage of larviculture might be due to the depletion of the previously mentioned ions especially that of magnesium.

    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.

    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. 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

    Science.gov (United States)

    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.

    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.

    Full Text Available This study investigates the neuronal correlates of empathic processing in childrenaged 4 to 8 years, an age range discussed to be crucial for the development ofempathy. 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

    Most pollutants enter the leaf through tiny pores in the leaf surfaces and cause internal leaf damage. These tiny pores of stomates are the passages through which gas exchanges take place during photosynthesis and respiration. At a given pollutant level, other things being equal, a plant growing under conditions of high humidity will take in more pollutant and become more severly damaged than a plant growing under arid conditions. Once the pollutants have entered the leaf, each has its own characteristic type of interaction with the plant tissues. Small animals living along a busy highway, could accumulate lead by consuming lead-containing herbage or breathing lead laden air. Fluoride air pollutants damaging to plants are hydrogen fluoride and silicon tetrafluoride. The characteristic symptom of fluoride damage is necrosis on leaf tips and margins where the fluoride has been concentrated. Ethylene causes a general reduction in growth, decreases apical dominance, and stimulates lateral development. Ozone enters through the stomates and attacks the palisade tissue, while sulfur dioxide enters the leaf through the stomates and reacts with water on the moist cell surfaces to form sulfite which is in turn slowly oxidized to sulfate. Peroxyacetyl nitrate enters the leaf through the stomates where it attacks the cells of the spongy mesophyll, and nitrogen dioxide causes growth reduction and defoliation at concentrations often present in polluted areas. Air pollution is having a detrimental economic effect on agriculture in the nation, while also altering the ecological relationships of plants and animals. Fortunately, most species have a great wealth of genetic variation in sensitivity to air pollution. The mechanism of plant tolerance to air pollutants is mentioned.

    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.

    Full Text Available The relationship between bladder tumors and Schistosoma haematobium is well known, but only sporadic cases of bladder infection due to Schistosoma mansoni have been reported. In this case, a 48-year-old woman with macroscopic hematuria, dysuria and a palpable abdominal mass was investigated. Ultrasound showed a large exophytic mass in the bladder. Transurethral resection of the bladder revealed viable eggs of Schistosoma mansoni. The patient was treated clinically with oxamniquine and surgery was performed to resect the large mass. This case shows that schistosomiasis Mansoni in the bladder can simulate bladder cancer.É bem conhecida a relação entre tumor vesical e Schistosoma haematobium, porém somente casos esporádicos de infecção vesical por Schistosoma mansoni foram relatados. Neste caso, uma mulher de 48 anos com hematúria macroscópica, disúria e massa abdominal palpável foi investigada, ultra-sonografia mostrou uma grande massa exofítica na bexiga. A ressecção transuretral de bexiga evidenciou ovos viáveis de Schistosoma mansoni. A paciente foi tratada clinicamente com oxaminiquine e uma cirurgia foi realizada para ressecar a grande massa. Este caso mostra que a esquistossomose mansônica vesical pode simular um câncer vesical.

  19. Calculating salt loads to Great Salt Lake and the associated uncertainties for water year 2013; updating a 48 year old standard

    Science.gov (United States)

    Shope, Christopher L.; Angeroth, Cory E.

    2015-01-01

    Effective management of surface waters requires a robust understanding of spatiotemporal constituent loadings from upstream sources and the uncertainty associated with these estimates. We compared the total dissolved solids loading into the Great Salt Lake (GSL) for water year 2013 with estimates of previously sampled periods in the early 1960s.We also provide updated results on GSL loading, quantitatively bounded by sampling uncertainties, which are useful for current and future management efforts. Our statistical loading results were more accurate than those from simple regression models. Our results indicate that TDS loading to the GSL in water year 2013 was 14.6 million metric tons with uncertainty ranging from 2.8 to 46.3 million metric tons, which varies greatly from previous regression estimates for water year 1964 of 2.7 million metric tons. Results also indicate that locations with increased sampling frequency are correlated with decreasing confidence intervals. Because time is incorporated into the LOADEST models, discrepancies are largely expected to be a function of temporally lagged salt storage delivery to the GSL associated with terrestrial and in-stream processes. By incorporating temporally variable estimates and statistically derived uncertainty of these estimates,we have provided quantifiable variability in the annual estimates of dissolved solids loading into the GSL. Further, our results support the need for increased monitoring of dissolved solids loading into saline lakes like the GSL by demonstrating the uncertainty associated with different levels of sampling frequency.

    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.

    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.

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

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

  7. Man-machine supervision

    International Nuclear Information System (INIS)

    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. The Cities for No Man

    Directory of Open Access Journals (Sweden)

    2015-12-01

    Full Text Available Contemporary urban concept asserts the need to create spaces for man. However, the idea of a "man" transformed radically from the moment of its appearance. The book by the famous Danish architect and consultant in urban design Jan Gehl, "Cities for people", is a key example to demonstrate the ambiguity of this position. The book focuses on the concept of "man", which was abandoned in modernism. And modernism is criticized by the author. But in reality, it is not about the return to the "man", but about designing "new man". Gehl describes a new urban ideology, in which his understanding of "man" coincides with the postmodernist understanding of its absence. The "man" is multiple functions, actors of the city, and it refers to the bodies that are indistinguishable in their anonymity.

  12. Pathways to man

    International Nuclear Information System (INIS)

    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

    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.

  20. AIAA Survivability Technical Committee Draft

    Science.gov (United States)

    Shipman, Jim; Williamson, Joel

    1997-01-01

    A relatively new area of interest in aerospace systems survivability is the growing threat of spacecraft penetration by orbital debris. Orbital debris, or "space junk", is composed of the man-made remnants of non-functioning spacecraft still orbiting the Earth. NASA estimates that there are currently over 100,000 orbital debris particles 1 centimeter in diameter or larger that cannot be tracked by existing radar, with the population growing at approximately 4% per year in low earth orbits. With an average velocity of over 8.7 km/sec, these projectiles can penetrate and disable many vulnerable spacecraft systems. Since the likelihood of spacecraft penetration increases with spacecraft surface area, large spacecraft (such as the International Space Station) and communication satellite fleets (such as Iridium) have begun to adopt survivability enhancement strategies similar to those employed by combat aircraft. Collision avoidance maneuvers are commonly practiced by the Space Shuttle and are planned by the International Space Station to decrease their susceptibility to impact by trackable orbital debris; likewise, improved shielding, internal equipment placement, and improved crew operations following penetration can reduce the vulnerability of spacecraft to loss following orbital debris impact. Computer simulations such as the Manned Spacecraft and Crew Survivability (MSCSurv) program at the NASA-Marshall Space Flight Center have recently been developed to quantify and reduce the likelihood of crew or spacecraft loss following orbital debris penetration. The AIAA Survivability Technical Committee is working to enable the transfer of military-developed survivability technologies to help the aerospace industry cope with this growing threat.

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.

  3. Rich man, poor man: developmental differences in attributions and perceptions.

    Sigelman, Carol K

    2012-11-01

    In an examination guided by cognitive developmental and attribution theory of how explanations of wealth and poverty and perceptions of rich and poor people change with age and are interrelated, 6-, 10-, and 14-year-olds (N=88) were asked for their causal attributions and trait judgments concerning a rich man and a poor man. First graders, like older children, perceived the rich man as more competent than the poor man. However, they had difficulty in explaining wealth and poverty, especially poverty, and their trait perceptions were associated primarily with their attributions of wealth to job status, education, and luck. Fifth and ninth graders more clearly attributed wealth and poverty to the equity factors of ability and effort and based their trait perceptions on these attributions. Although the use of structured attribution questions revealed more understanding among young children than previous studies have suggested, the findings suggest a shift with age in the underlying bases for differential evaluation of rich and poor people from a focus on good outcomes associated with wealth (a good education and job) to a focus on personal qualities responsible for wealth (ability and effort).

    Suicide is a global phenomenon in all regions of the world affecting people of all age groups. It has detrimental consequences on patients, their families, and the community as a whole. There have been numerous risk factors described for suicide including mental illness, stressful life situations, loss of social support, and general despair. The association of suicide with Islam has not been extensively studied. The common impression from clinical practice is that being a practicing Muslim reduces the risk of suicide. Another factor associated with suicide is starting a patient on antidepressants. However, this has been questioned recently. This report describes a middle-aged man with depression and multiple social stressors who survived a serious suicide attempt. The discussion will focus on the factors that lead him to want to end his life and the impact of the assumed protective factors such as religious belief and family support on this act of self-harm. Such patients can be on the edge when there is an imbalance between risk factors (such as depression, insomnia, and psychosocial stressors) and protective factors (like religious affiliation and family support). All physicians are advised to assess the suicide risk thoroughly in patients with depression regardless of any presumed protective factor. PMID:27602193

The association of suicide with Islam has not been extensively studied. The common impression from clinical practice is that being a practicing Muslim reduces the risk of suicide. Another factor associated with suicide is starting a patient on antidepressants. However, this has been questioned recently. This report describes a middle-aged man with depression and multiple social stressors who survived a serious suicide attempt. The discussion will focus on the factors that lead him to want to end his life and the impact of the assumed protective factors such as religious belief and family support on this act of self-harm. Such patients can be on the edge when there is an imbalance between risk factors (such as depression, insomnia, and psychosocial stressors) and protective factors (like religious affiliation and family support).

  18. Man's Impact on Groundwater Systems

    International Nuclear Information System (INIS)

    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

    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.'

    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 ...

  1. Deformation of Man Made Objects

    KAUST Repository

    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.

    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

    Invisible Man is a representative work of black literature in America. In this novel, the writer Ralph Ellison depicts the hero’s growth experience in the white dominated society with his unique narrative techniques. As an individual in a society, the hero in this novel gradually realizes that he is an invisible man in the white dominated society and he doesn ’t have the social sta-tus which can be recognized by the white at all. To change this situation, the hero in this novel suffers many difficulties and hard-ships with an attempt to prove his existence in front of the white and the numerous black fellows and obtain his own identity as a black man which will be recognized by others. This paper tries to explore African American ’s pursuit of identity in Invisible Man by interpreting Ellison’s Invisible Man.

    Full Text Available Throughout its history in Old High German (OHG, Middle High German, Early New High German, and Modern German (ModG, the word Mann "man" has exhibited a high degree of productivity and linguistic flexibility. It has ranged morphosyntactically from a full noun (OHG man "man", compounded noun (OHG werolt.man "human, mortal", affixoid (ModG Sports.mann "athlete", indefinite pronoun (ModG man "one", to something approaching zero (undergoing demorphologization in the OHG compound gom.man "husband, man". The affixoid notion and its usefulness in morphology have been controversial in the literature (e.g., Schmidt 1987. Relatively recently, Stevens (2005 proposed criteria for the category affixoid, and a number of standard German grammatical and etymological references (e.g., Duden 1995 have been utilizing this term. This study involves examining modern usage of the form -mann as found in the online Spiegel newsmagazine's database, as well as the collection of historical data primarily on the forms of German -mann from the robust Titus database in Frankfurt.

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

    Science.gov (United States)

    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

    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

  4. Survival of microorganisms in smectite clays: Implications for Martian exobiology

    Science.gov (United States)

    Moll, Deborah M.; Vestal, J. Robie

    1992-08-01

    Manned exploration of Mars may result in the contamination of that planet with terrestrial microbes, a situation requiring assessment of the survival potential of possible contaminating organisms. In this study, the survival of Bacillus subtilis, Azotobacter chroococcum, and the enteric bacteriophage MS2 was examined in clays representing terrestrial (Wyoming type montmorillonite) or Martian (Fe 3+-montmorillonite) soils exposed to terrestrial and Martian environmental conditions of temperature and atmospheric pressure and composition, but not to UV flux or oxidizing conditions. Survival of bacteria was determined by standard plate counts and biochemical and physiological measurements over 112 days. Extractable lipid phosphate was used to measure microbial biomass, and the rate of 14C-acetate incorporation into microbial lipids was used to determine physiological activity. MS2 survival was assayed by plaque counts. Both bacterial types survived terrestrial or Martian conditions in Wyoming montmorillonite better than Martian conditions in Fe 3+-montmorillonite. Decreased survival may have been caused by the lower pH of the Fe 3+-montmorillonite compared to Wyoming montmorillonite. MS2 survived simulated Mars conditions better than the terrestrial environment, likely due to stabilization of the virus caused by the cold and dry conditions of the simulated Martian environment. The survival of MS2 in the simulated Martian environment is the first published indication that viruses may be able to survive in Martian type soils. This work may have implications for planetary protection for future Mars missions.

    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.

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

  10. 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.

    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...

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.

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

    Directory of Open Access Journals (Sweden)

    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.

    2002-09-01

    For realizing the flexible man-machine collaboration, understanding of facial expressions and gestures is not negligible. In our method, we proposed a hierarchical recognition approach, for the understanding of human emotions. According to this method, the facial AFs (action features) were firstly extracted and recognized by using histograms of optical flow. Then, based on the facial AFs, facial expressions were classified into two calsses, one of which presents the positive emotions, and the other of which does the negative ones. Accordingly, the facial expressions belonged to the positive class, or the ones belonged to the negative class, were classified into more complex emotions, which were revealed by the corresponding facial expressions. Finally, the system architecture how to coordinate in recognizing facil action features and facial expressions for man-machine collaboration was proposed.

    Full Text Available The case of the unknown man who died mysteriously at Somerton Beach in South Australia in 1948 remains an open police investigation, although the trail today has grown fairly cold. Revisiting the case, and the responses the mystery of his person have elicited, enables a special historical insight into Australia’s postwar society, and the ways in which the past is continually reshaped by the subjectivities of the present. Further, an unsolved case such as this provides for a unique kind of historical project. The limitations of a history without a coherent centre are myriad, yet so are the possibilities.  In this article, I explore the possibilities of an ‘unsolved history’, a history of dead ends, and argue that it is the very unknowable-ness of the Somerton Man that allows for a perception of history as multi-dimensional and complex.

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

    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

  17. Man-machine interface for the MFTF

    Energy Technology Data Exchange (ETDEWEB)

    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.

    April 12, 1961 "Attention! This is Radio Moscow speaking...The world's first satellite spaceship, Vostock, with a man aboard, was put into orbit round the Earth." Soviet Union cosmonaut Yuri A. Gagarin becomes the first person to fly in space, completing one orbit in 108 minutes. April 5, 2001 As NASA prepares to fly the final Shuttle missions to the International Space Station, Russia launches Soyuz TMA 21 (code-named 'Yuri Gagarin') with the 28th ISS Expedition crew aboard, celebrating 50 years of manned spaceflight. Meanwhile, in China, preparations continue for launching the nation's first Space Station (called Tiangong 1 - or Heavenly Palace 1) later in the year. The sixth decade of manned spaceflight orbital operations has truly began. At this point in the history of human space exploration, it is timely to review the first five decades of adventure and look forward to the next decade and what it might bring. Several notable anniversaries celebrated in 2011 make it the right time to reflect and pay homa...

  19. TaxMan: a taxonomic database manager

    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

    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.

    2009-12-01

    We study the survival of extreme opinions in various processes of consensus formation. All the opinions are treated equally and subjected to the same rules of changing. We investigate three typical models to reach a consensus in each case: (A) personal influence, (B) influence from surroundings, and (C) influence to surroundings. Starting with uniformly distributed random opinions, our calculated results show that the extreme opinions can survive in both models (A) and (B), but not in model (C). We obtain a conclusion that both personal influence and passive adaptation to the environment are not sufficient enough to eradicate all the extreme opinions. Only the active persuasion to change the surroundings eliminates the extreme opinions completely.

    Estimating a patient's mortality risk is important in making treatment decisions. Survival trees are a useful tool and employ recursive partitioning to separate patients into different risk groups. Existing 'loss based' recursive partitioning procedures that would be used in the absence of censoring have previously been extended to the setting of right censored outcomes using inverse probability censoring weighted estimators of loss functions. In this paper, we propose new 'doubly robust' extensions of these loss estimators motivated by semiparametric efficiency theory for missing data that better utilize available data. Simulations and a data analysis demonstrate strong performance of the doubly robust survival trees compared with previously used methods. Copyright © 2016 John Wiley & Sons, Ltd. PMID:27037609

    1994-01-01

    In order to gain knowledge about the potential contributions of comets and cosmic dust to the origin of life on Earth, we need to explore the survivability of their potential organic compounds on impact and the formation of secondary products that may have arisen from the chaotic events sustained by the carriers as they fell to Earth. We have performed a series of hypervelocity impact experiments using carbon-bearing impactors (diamond, graphite, kerogens, PAH crystals, and Murchison and Nogoya meteorites) into Al plate targets at velocities - 6 km/s. Estimated peak shock pressures probably did not exceed 120 GPa and peak shock temperatures were probably less than 4000 K for times of nano- to microsecs. Nominal crater dia. are less than one mm. The most significant results of these experiments are the preservation of the higher mass PAHs (e. g., pyrene relative to napthalene) and the formation of additional alkylated PAHs. We have also examined the residues of polystyrene projectiles impacted by a microparticle accelerator into targets at velocities up to 15 km/s. This talk will discuss the results of these experiments and their implications with respect to the survival of carbonaceous deliverables to early Earth. The prospects of survivability of organic molecules on "intact" capture of cosmic dust in space via soft: and hard cosmic dust collectors will also be discussed.

    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

    International Nuclear Information System (INIS)

    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.

    International Nuclear Information System (INIS)

    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

    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...

    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.

    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

  7. 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

    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.

  9. Abstraction of man-made shapes

    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.

  10. Proposal for a remotely manned space station

    Minsky, Marvin

    1990-01-01

    The United States is in trouble in space. The costs of the proposed Space Station Freedom have grown beyond reach, and the present design is obsolete. The trouble has come from imagining that there are only two alternatives: manned vs. unmanned. Both choices have led us into designs that do not appear to be practical. On one side, the United States simply does not possess the robotic technology needed to operate or assemble a sophisticated unmanned space station. On the other side, the manned designs that are now under way seem far too costly and dangerous, with all of its thousands of extravehicular activity (EVA) hours. More would be accomplished at far less cost by proceeding in a different way. The design of a space station made of modular, Erector Set-like parts is proposed which is to be assembled using earth-based remotely-controlled binary-tree telerobots. Earth-based workers could be trained to build the station in space using simulators. A small preassembled spacecraft would be launched with a few telerobots, and then, telerobots could be ferried into orbit along with stocks of additional parts. Trained terrestrial workers would remotely assemble a larger station, and materials for additional power and life support systems could be launched. Finally, human scientists and explorers could be sent to the space station. Other aspects of such a space station program are discussed.

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.

    Ishwaran, Hemant; Kogalur, Udaya B

    2010-07-01

    We prove uniform consistency of Random Survival Forests (RSF), a newly introduced forest ensemble learner for analysis of right-censored survival data. Consistency is proven under general splitting rules, bootstrapping, and random selection of variables-that is, under true implementation of the methodology. Under this setting we show that the forest ensemble survival function converges uniformly to the true population survival function. To prove this result we make one key assumption regarding the feature space: we assume that all variables are factors. Doing so ensures that the feature space has finite cardinality and enables us to exploit counting process theory and the uniform consistency of the Kaplan-Meier survival function.

    Regression analysis of survival data, and more generally event history data, is typically based on Cox's regression model. We here review some recent methodology, focusing on the limitations of Cox's regression model. The key limitation is that the model is not well suited to represent time......-varying effects. We start by considering classical and also more recent goodness-of-fit procedures for the Cox model that will reveal when the Cox model does not capture important aspects of the data, such as time-varying effects. We present recent regression models that are able to deal with and describe...... such time-varying effects. The introduced models are all applied to data on breast cancer from the Norwegian cancer registry, and these analyses clearly reveal the shortcomings of Cox's regression model and the need for other supplementary analyses with models such as those we present here....

  14. Cosmological magnetic field survival

    CERN Document Server

    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...

    This paper attempts to capture some of the technical and national challenges facing the design of America's next manned launch system (MLS). There are three basic paths for pursuing tomorrow's MLS; each with variations. Some characteristics that will be sought regardless of the concept selected include low development (or front-end) and life-cycle costs, safety, operability, availability, and a host of other 'ilities'. In order to discriminate among the concepts, a robust design environment and a variety of new and improved analysis tools are needed that produce critical metrics in a timely, efficient manner from a large study space. This paper presents some of the challenges in development, integration, and application of optimization, costing, operations modeling, and several engineering disciplinary tools including geometry modeling, structures, aerodynamics/aeroheating, and trajectory/performance.

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

  20. Treatment of radiostrontium uptake in man

    International Nuclear Information System (INIS)

    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.

    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.

  2. Cytologic-Biochemical Radiation Dosimeters in Man

    International Nuclear Information System (INIS)

    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)

    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.

    Science.gov (United States)

    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.

  6. The methodology of man-machine systems

    International Nuclear Information System (INIS)

    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)

  7. Values and the quantum conception of man

    Energy Technology Data Exchange (ETDEWEB)

    Stapp, H.P.

    1995-06-01

    Classical mechanics is based upon a mechanical picture of nature that is fundamentally incorrect. It has been replaced at the basic level by a radically different theory: quantum mechanics. This change entails an enormous shift in one`s basic conception of nature, one that can profoundly alter the scientific image of man himself. Self-image is the foundation of values, and the replacement of the mechanistic self-image derived from classical mechanics by one concordant with quantum mechanics may provide the foundation of a moral order better suited to today`s times, a self-image that endows human life with meaning, responsibility, and a deeper linkage to nature as a whole.

    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.

    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.

  12. Measurement of total body radioactivity in man

    International Nuclear Information System (INIS)

    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.)

  14. MAN1B1 deficiency: an unexpected CDG-II.

    Directory of Open Access Journals (Sweden)

    Daisy Rymen

    Full Text Available Congenital disorders of glycosylation (CDG are a group of rare metabolic diseases, due to impaired protein and lipid glycosylation. In the present study, exome sequencing was used to identify MAN1B1 as the culprit gene in an unsolved CDG-II patient. Subsequently, 6 additional cases with MAN1B1-CDG were found. All individuals presented slight facial dysmorphism, psychomotor retardation and truncal obesity. Generally, MAN1B1 is believed to be an ER resident alpha-1,2-mannosidase acting as a key factor in glycoprotein quality control by targeting misfolded proteins for ER-associated degradation (ERAD. However, recent studies indicated a Golgi localization of the endogenous MAN1B1, suggesting a more complex role for MAN1B1 in quality control. We were able to confirm that MAN1B1 is indeed localized to the Golgi complex instead of the ER. Furthermore, we observed an altered Golgi morphology in all patients' cells, with marked dilatation and fragmentation. We hypothesize that part of the phenotype is associated to this Golgi disruption. In conclusion, we linked mutations in MAN1B1 to a Golgi glycosylation disorder. Additionally, our results support the recent findings on MAN1B1 localization. However, more work is needed to pinpoint the exact function of MAN1B1 in glycoprotein quality control, and to understand the pathophysiology of its deficiency.

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

    Full Text Available The rapid development of science and technology from the mid-20th century, on one hand, and increasing world population as well as decreasing of natural resources on the other has raised the risk of escalating social conflicts. Regarding this facts, it is inevitable to admit that the future of mankind lies in acceptable moral and social implementation of this technologies. Having that in mind, many questions have been generated about responsible applications of nanotechnologies: about the positive and negative effects of their usage, about patterns of their socio-spatial distribution both at global and national level, about economic development of states who use those technologies, and their possible effect of individual health and biosphere preservation. Regarding those questions, it is necessary to use knowledge of nature science as well as knowledge of philosophy, sociology, etc., in order to analyze the level of development and life conditions in human communities and differentiate between “mere”, “miserable”, “idealistic“, “irresponsible“ and “acceptable“ survival. Starting from sociological context and following Potter’s concepts, this article argues for the concept of consurvivality that is durable, acceptable, sustainable, realistic and global.

  19. Operational Philosophy Concerning Manned Spacecraft Cabin Leaks

    Science.gov (United States)

    DeSimpelaere, Edward

    2011-01-01

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

    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.)

  9. Estimation of dose to man from environmental tritium

    International Nuclear Information System (INIS)

    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

    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

    Studies were conducted on 15 healthy young soldiers to evaluate the effect of a cold acclimatization schedule on the thermoregulatory and metabolic activity on exposure to acute cold stress. These men were exposed to cold (10‡C) for 4 h daily wearing only shorts for 21 days, in a cold chamber. They were subjected to a standard cold test at 10 ± 1‡C the day 1, 6, 11 and 21. The subjects were made to relax in a thermoneutral room (26 28‡C) for 1 h and their heart rate, blood pressure, oxygen consumption, oral temperature, mean skin temperature, mean body temperature, peripheral temperatures, and shivering activity were recorded. Then they were exposed to 10‡C and measurements were repeated at 30 min intervals, for 2 h. The cold induced vasodilatation (CIVD), cold pressor response and thermoregulatory efficiency tests were measured initially and at the end of acclimatization schedule. The data show that the procedure resulted in elevated resting metabolism, less fall in body temperature during acute cold stress, reduction in shivering, improvement in CIVD and thermoregulatory efficiency and less rise in BP and HR during cold pressor response. The data suggest the possibility of cold acclimatization in man by repeated exposure to moderately severe cold stress.

  13. Metabolic studies in man using stable isotopes

    International Nuclear Information System (INIS)

    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

  14. Facts, Principles and the Third Man

    Directory of Open Access Journals (Sweden)

    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.

  15. 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.

  16. Environmental pathways of radioactivity to man

    International Nuclear Information System (INIS)

    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.

    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.

    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.

    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.

    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

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

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

    International Nuclear Information System (INIS)

    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

    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).

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

    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.

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

    Institute of Scientific and Technical Information of China (English)

    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.

    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 ...

    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...

    Full Text Available We report a case of metastatic bladder cancer developing in a young man with cystic fibrosis (CF that was initially diagnosed as ureterolithiasis and managed as renal colic. With the improved survival of patients with CF, an increasing burden of extrapulmonary disease manifestations is apparent. Renal colic is observed at an increased frequency in patients with CF relative to the general population and is a commonly recognized cause of hematuria. However, CF patients harboring a malignancy are recognized to be at increased risk of delayed identification owing to atypical symptoms and lack of demographic risk factors. This case illustrates how investigations to rule out malignancy are warranted in those CF patients not responding to therapies directed towards presumptive diagnoses.

    2015-01-01

    This technical paper documents Kennedy Space Centers Independent Assessment team work completed on three assessments for the Ground Systems Development and Operations (GSDO) Program to assist the Chief Safety and Mission Assurance Officer (CSO) and GSDO management during key programmatic reviews. The assessments provided the GSDO Program with an analysis of how egress time affects the likelihood of astronaut and worker survival during an emergency. For each assessment, the team developed probability distributions for hazard scenarios to address statistical uncertainty, resulting in survivability plots over time. The first assessment developed a mathematical model of probabilistic survivability versus time to reach a safe location using an ideal Emergency Egress System at Launch Complex 39B (LC-39B); the second used the first model to evaluate and compare various egress systems under consideration at LC-39B. The third used a modified LC-39B model to determine if a specific hazard decreased survivability more rapidly than other events during flight hardware processing in Kennedys Vehicle Assembly Building (VAB).Based on the composite survivability versus time graphs from the first two assessments, there was a soft knee in the Figure of Merit graphs at eight minutes (ten minutes after egress ordered). Thus, the graphs illustrated to the decision makers that the final emergency egress design selected should have the capability of transporting the flight crew from the top of LC 39B to a safe location in eight minutes or less. Results for the third assessment were dominated by hazards that were classified as instantaneous in nature (e.g. stacking mishaps) and therefore had no effect on survivability vs time to egress the VAB. VAB emergency scenarios that degraded over time (e.g. fire) produced survivability vs time graphs that were line with aerospace industry norms.

  16. Mars survival handbook: where to find water

    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.

    The concept of frailty offers a convenient way to introduce unobserved heterogeneity and associations into models for survival data. In its simplest form, frailty is an unobserved random proportionality factor that modifies the hazard function of an individual or a group of related individuals. "Frailty Models in Survival Analysis" presents a comprehensive overview of the fundamental approaches in the area of frailty models. The book extensively explores how univariate frailty models can represent unobserved heterogeneity. It also emphasizes correlated frailty models as extensions of

  20. Small reactor power systems for manned planetary surface bases

    International Nuclear Information System (INIS)

    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

    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

    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

    In the present paper, we report for the first time the tissue distribution of ibogaine and noribogaine, the main metabolite of ibogaine, in a 48-year-old Caucasian male, with a history of drug abuse, found dead at his home after a poisoning involving the ingestion of root bark from the shrub Tabernanthe iboga. Ibogaine and noribogaine were quantified in tissues and fluids using a fully validated liquid chromatography-electrospray mass spectrometry method. Apart from cardiac tissue, ibogaine and noribogaine were identified in all matrices investigated. The highest concentrations were found in spleen, liver, brain, and lung. The tissue/subclavian blood concentration ratios averaged 1.78, 3.75, 1.16, and 4.64 for ibogaine and 0.83, 2.43, 0.90, and 2.69 for noribogaine for spleen, liver, brain, and lung, respectively. Very low concentrations of the two drugs were found in the prostatic tissue. Both ibogaine and noribogaine are secreted in the bile and cross the blood-brain barrier. Four other compounds were detected in most of the studied matrices. One of them was identified as ibogamine. Unfortunately, we were not able to positively identify the other three compounds because of the unavailability of reference substances. Two of them could possibly be attributed to the following oxidation products: iboluteine and desmethoxyiboluteine. The third compound could be ibogaline.

It is necessary to adopt the state of the art technologies to present and make bi-directional the interaction of users with cultural heritage objects. In this work, we present two different applications of novel technologies applied to the Vitruvian man of Leonardo. The first application is the mirror that exploits a 3D depth sensor to compare the proportions of a user with the perfect ones of the Vitruvian man. The second application is a complex interaction between a complete novel 3D model of the Leonardo’s Vitruvian Man, sounds and image effects inside a 360-degrees hologram. These two systems are the results of interaction between academia and the 3D EVE spin-off company.

    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 (1) the availability of compact energy sources for power and propulsion, (2) the creation of permanent manned habitats in space, and (3) 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 will be discussed, with emphasis on derivatives from the nuclear rocket technology.

    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.

    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.

  11. Kant's BetterMan and the Confucian Junzi

    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.

  12. Aircraft Combat Survivability Calculation Based on Combination Weighting and Multiattribute Intelligent Grey Target Decision Model

    2016-01-01

    Full Text Available Aircraft combat survivability is defined as the capability of an aircraft to avoid or withstand a man-made hostile environment, which has been increasingly important. In order to give a rational calculation of aircraft combat survivability, an integrated method based on combination weighting and multiattribute intelligent grey target decision model is proposed. Firstly, an evaluation index system containing susceptibility index and vulnerability index as well as their subindexes is established. Then a multiattribute intelligent grey target decision model is introduced. A combination weighting method is brought up based on a modified AHP (analytic hierarchy process method and the entropy method, offering a rational weight for various indexes. Finally, utilize the multiattribute intelligent grey target decision model to assess the aircraft combat survivability of aircraft, verified by a practical case of five aircraft. The results show that the proposed method is effective and has a great value in engineering application, which will provide useful references for other projects’ evaluation.

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

    International Nuclear Information System (INIS)

    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)

    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.

    International Nuclear Information System (INIS)

    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)

    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

    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.

    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.

    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.

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.

    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...

    International Nuclear Information System (INIS)

    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.

  8. Mannans and endo-β-mannanases (MAN) in Brachypodium distachyon: expression profiling and possible role of the BdMAN genes during coleorhiza-limited seed germination.

    2015-07-01

    Immunolocalization of mannans in the seeds of Brachypodium distachyon reveals the presence of these polysaccharides in the root embryo and in the coleorhiza in the early stages of germination (12h), decreasing thereafter to the point of being hardly detected at 27h. Concurrently, the activity of endo-β-mannanases (MANs; EC 3.2.1.78) that catalyse the hydrolysis of β-1,4 bonds in mannan polymers, increases as germination progresses. The MAN gene family is represented by six members in the Brachypodium genome, and their expression has been explored in different organs and especially in germinating seeds. Transcripts of BdMAN2, BdMAN4 and BdMAN6 accumulate in embryos, with a maximum at 24-30h, and are detected in the coleorhiza and in the root by in situ hybridization analyses, before root protrusion (germination sensu stricto). BdMAN4 is not only present in the embryo root and coleorhiza, but is abundant in the de-embryonated (endosperm) imbibed seeds, while BdMAN2 and BdMAN6 are faintly expressed in endosperm during post-germination (36-42h). BdMAN4 and BdMAN6 transcripts are detected in the aleurone layer. These data indicate that BdMAN2, BdMAN4 and BdMAN6 are important for germination sensu stricto and that BdMAN4 and BdMAN6 may also influence reserve mobilization. Whether the coleorhiza in monocots and the micropylar endosperm in eudicots have similar functions, is discussed.

    We consider stochastic growth models to represent population subject to catastrophes. We analyze the subject from different set ups considering or not spatial restrictions, whether dispersion is a good strategy to increase the population viability. We find out it strongly depends on the effect of a catastrophic event, the spatial constraints of the environment and the probability that each exposed individual survives when a disaster strikes.

    Prognostic studies often have to deal with two important challenges: (i) separating effects of predictions on different 'competing' events and (ii) uncertainty about cause of death. Multistate Markov models permit multivariable analyses of competing risks of, for example, mortality versus disease recurrence. On the other hand, relative survival methods help estimate disease-specific mortality risks even in the absence of data on causes of death. In this paper, we propose a new Markov relative survival (MRS) model that attempts to combine these two methodologies. Our MRS model extends the existing multistate Markov piecewise constant intensities model to relative survival modeling. The intensity of transitions leading to death in the MRS model is modeled as the sum of an estimable excess hazard of mortality from the disease of interest and an 'offset' defined as the expected hazard of all-cause 'natural' mortality obtained from relevant life-tables. We evaluate the new MRS model through simulations, with a design based on registry-based prognostic studies of colon cancer. Simulation results show almost unbiased estimates of prognostic factor effects for the MRS model. We also applied the new MRS model to reassess the role of prognostic factors for mortality in a study of colorectal cancer. The MRS model considerably reduces the bias observed with the conventional Markov model that does not permit accounting for unknown causes of death, especially if the 'true' effects of a prognostic factor on the two types of mortality differ substantially.

  14. Illusory contour formation survives crowding.

    2012-06-12

    Flanked objects are difficult to identify using peripheral vision due to visual crowding, which limits conscious access to target identity. Nonetheless, certain types of visual information have been shown to survive crowding. Such resilience to crowding provides valuable information about the underlying neural mechanism of crowding. Here we ask whether illusory contour formation survives crowding of the inducers. We manipulated the presence of illusory contours through the (mis)alignment of the four inducers of a Kanizsa square. In the inducer-aligned condition, the observers judged the perceived shape (thin vs. fat) of the illusory Kanizsa square, manipulated by small rotations of the inducers. In the inducer-misaligned condition, three of the four inducers (all except the upper-left) were rotated 90°. The observers judged the orientation of the upper-left inducer. Crowding of the inducers worsened observers' performance significantly only in the inducer-misaligned condition. Our findings suggest that information for illusory contour formation survives crowding of the inducers. Crowding happens at a stage where the low-level featural information is integrated for inducer orientation discrimination, but not at a stage where the same information is used for illusory contour formation.

  15. LATERAL SURVIVAL: AN OT ACCOUNT

    Directory of Open Access Journals (Sweden)

    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.

  16. Yolk androgens reduce offspring survival.

    2000-07-22

    Females may favour some offspring over others by differential deposition of yolk hormones. In American kestrels (Falco sparverius), we found that yolks of eggs laid late in the sequence of a clutch had more testosterone (T) and androstenedione (A4) than yolks of first-laid eggs. To investigate the effects of these yolk androgens on nestling 'fitness', we injected both T and A4 into the yolks of first-laid eggs and compared their hatching time, nestling growth and nestling survival with those of first-laid eggs in which we injected vehicle as a control. Compared to controls, injection of T and A4 at a dose intended to increase their levels to those of later-laid eggs delayed hatching and reduced nestling growth and survival rates. Yolk androgen treatment of egg 1 had no effect on survival of siblings hatching from subsequently laid eggs. The adverse actions of yolk androgen treatment in the kestrel are in contrast to the favourable actions of yolk T treatment found previously in canaries (Serinus canaria). Additional studies are necessary in order to determine whether the deposition of yolk androgens is an adaptive form of parental favouritism or an adverse by-product of endocrine processes during egg formation. Despite its adaptive significance, such 'transgenerational' effects of steroid hormones may have helped to evolutionarily shape the hormonal mechanisms regulating reproduction. PMID:10983830

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

    Directory of Open Access Journals (Sweden)

    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.

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

    International Nuclear Information System (INIS)

    '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.

    This report consolidates research carried out at Clemson University and Stanford University where a series of measurements were undertaken to identify the man-made radiation present in four bands used by rather different services, namely, L1 Band (1563.42 1587.42 MHz), the Unified S-Band (2025 2110 MHz), the 2.4 GHz Industrial, Scientific and Medical (ISM) Band (2400 2482.50 MHz), and the 23.6-24.0 GHz Passive Sensing Band. Results show that there were distinctive differences in the measurement data in the frequency bands, which should be expected based on the function/regulation associated with each. The GPS L1 Band had little to none terrestrial man-made sources, but the ISM 2.4 GHz Band had a large number of man-made sources regardless of the site and the time. The Unified S Band showed mixed results depending on the sites. The Passive Sensing Band does not contain appreciable man-made radiation.

    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

  18. Survival strategies in arctic ungulates

    Directory of Open Access Journals (Sweden)

    N. J. C. Tyler

    1990-09-01

    Full Text Available Arctic ungulates usually neither freeze nor starve to death despite the rigours of winter. Physiological adaptations enable them to survive and reproduce despite long periods of intense cold and potential undernutrition. Heat conservation is achieved by excellent insulation combined with nasal heat exchange. Seasonal variation in fasting metabolic rate has been reported in several temperate and sub-arctic species of ungulates and seems to occur in muskoxen. Surprisingly, there is no evidence for this in reindeer. Both reindeer and caribou normally maintain low levels of locomotor activity in winter. Light foot loads are important for reducing energy expenditure while walking over snow. The significance and control of selective cooling of the brain during hard exercise (e.g. escape from predators is discussed. Like other cervids, reindeer and caribou display a pronounced seasonal cycle of appetite and growth which seems to have an intrinsic basis. This has two consequences. First, the animals evidently survive perfectly well despite enduring negative energy balance for long periods. Second, loss of weight in winter is not necessarily evidence of undernutrition. The main role of fat reserves, especially in males, may be to enhance reproductive success. The principal role of fat reserves in winter appears to be to provide a supplement to, rather than a substitute for, poor quality winter forage. Fat also provides an insurance against death during periods of acute starvation.

    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

  20. Survival analysis of aging aircraft

    Science.gov (United States)

    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

    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.

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

    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

    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.

  7. Parental age at delivery and a man's semen quality

    DEFF Research Database (Denmark)

    2014-01-01

    STUDY QUESTION: Is parental age at delivery associated with a man's semen quality? SUMMARY ANSWER: In this large register-based study both mother's and father's age are found to have minimal effects on semen quality in men. WHAT IS KNOWN ALREADY: Both maternal and paternal age have been associated...... with a range of adverse health effects in the offspring. Given the varied health effects of parental age upon offspring, and the sensitivity of genital development to external factors, it is plausible that the age of a man's mother and father at conception may impact his reproductive health. To our knowledge...... this is the first examination of the effects of parental age on semen quality. STUDY DESIGN, SIZE, DURATION: A retrospective cohort study of 10 965 men with semen data and parental data. PARTICIPANTS/MATERIALS, SETTING, METHODS: The study was based on Danish men referred to the Copenhagen Sperm Analysis Laboratory...

  8. Hematologic syndrome in man modeled from mammalian lethality

    International Nuclear Information System (INIS)

    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.

    For the purpose of ensuring normal operations of Shenzhou (SZ) series of manned spacecrafts and cosmonauts' safety, Space Environment Monitors (SEM)are mounted on board SZ-2, 3, 4, 5. SEMs aim to detect the high energy particles, the low energy particles, charging potential, atmospheric desity and composition. Detection of SEMs enable us to understand better the space environment in the manned spacecraft's orbit, and to provide a good space environment services for the spacecraft and cosmonauts. In addition, by using the data from SEMs, we have achieved some scientific accomplishments, such as the energy spectra of precipitating electrons, the abnormal variety of atmospheric density and composition during geomagnetic disturbances, the electron angle distribution in the low orbit and so on.

  10. Fuzzy evaluation methodology for Man-Machine Task Allocation

    International Nuclear Information System (INIS)

    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)

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

    Directory of Open Access Journals (Sweden)

    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.

    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.

    Quantum secret sharing (QSS) and third-man quantum cryptography (TQC) are essential for advanced quantum communication; however, the low intensity and fragility of the multiphoton entanglement source in previous experiments have made their realization an extreme experimental challenge. Here, we develop and exploit an ultrastable high intensity source of four-photon entanglement to report an experimental realization of QSS and TQC. The technology developed in our experiment will be important for future multiparty quantum communication.

    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.

  20. Basic researches for advancement of man-machine systems

    International Nuclear Information System (INIS)

    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.

  1. Kinetics of lactate turnover and oxidation in man

    International Nuclear Information System (INIS)

    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)

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

    International Nuclear Information System (INIS)

    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

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

    International Nuclear Information System (INIS)

    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.

    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...

  5. Man-machine interface in the nuclear industry

    International Nuclear Information System (INIS)

    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

    Mast cells (MCs) are ubiquitous in the body, but they have historically been associated with allergies, and most recently with regulation of immunity and inflammation. However, it remains a puzzle why so many MCs are located in the diencephalon, which regulates emotions and in the genitourinary tract, including the bladder, prostate, penis, vagina and uterus that hardly ever get allergic reactions. A number of papers have reported that MCs have estrogen, gonadotropin and corticotropin-releasing hormone (CRH) receptors. Moreover, animal experiments have shown that diencephalic MCs increase in number during courting in doves. We had reported that allergic stimulation of nasal MCs leads to hypothalamic-pituitary adrenal (HPA) activation. Interestingly, anecdotal information indicates that female patients with mastocytosis or mast cell activation syndrome may have increased libido. Preliminary evidence also suggests that MCs may have olfactory receptors. MCs may, therefore, have been retained phylogenetically not only to "smell danger", but to promote survival and procreation.

  9. 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.

  12. Maternal nutrition, health, and survival.

    Science.gov (United States)

    2002-05-01

    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

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

    International Nuclear Information System (INIS)

    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

    Leafy greens are increasingly being recognized as an important vehicle for human noroviruses (HuNoV), which cause recurring gastroenteritis outbreaks. Leafy greens often become infected by phytopathogens in the field, which may cause symptoms on the edible parts. Whether plant pathogen infections enhance the survival of HuNoV on leafy greens is unknown. Lettuce and spinach plants were infected with a bacterium, Xanthomonas campestris pv. vitians strain 701a, and with Cucumber mosaic virus strain Fny, respectively. The survival rate of porcine sapovirus (SaV), a HuNoV surrogate, on infected and noninfected postharvest leaves was then assessed. In addition, acibenzolar-S-methyl, a commercial chemical elicitor of plant systemic defense, was used to assess whether stimulating the plant host defense affects the postharvest survival of SaV. Leaves harvested from control and treated plants were inoculated with SaV and incubated for 7 days at 4°C. The infectivity (tissue culture infectious dose affecting 50% of the culture [TCID50]/ml) and RNA (genomic equivalent/ml) titers of SaV were assayed using immunohistochemistry staining and SaV-specific TaqMan real-time reverse transcription PCR. Our results showed that cucumber mosaic virus Fny induced mild, nonnecrotic symptoms on spinach leaves and had no effect on SaV survival. In contrast, X. campestris pv. vitians 701a induced small localized necrotic lesions and significantly enhanced SaV survival on lettuce leaves. Treatment with acibenzolar-S-methyl was effective in reducing X. campestris pv. vitians 701a-induced lesions on infected lettuce plants but had no direct effect on SaV survival when used on healthy lettuce plants. These findings indicate that phytopathogen-induced necrotic lesions may enhance the postharvest survival of HuNoV on lettuce leaves. Therefore, preventive measures aiming to maintain healthy plants and minimize preharvest biological damage are expected to improve the safety of leafy greens.

    The protective efficacy of a DNA construct containing extra small virus antisense (XSVAS) gene of nodavirus encapsulated with chitosan nanoparticles (NPs) was investigated in giant freshwater prawn Macrobrachium rosenbergii (De Man, 1879). The delivery was carried out using oral and immersion methods. A plasmid concentration of 100 ng μL(-1) when conjugated with chitosan NPs was found to be more effective in increasing the survivability of the infected prawn. The particle mean size, zeta potential and loading efficiency percentage were 297 nm, 27 mV and 85%, respectively. The ability of the chitosan to form a complex with the plasmid was studied by agarose gel electrophoresis. The NPs were characterized by atomic force microscopy (AFM). Persistence study showed the presence of the DNA construct up to 30th day post-treatment. The oral treatment was found to be better than the immersion treatment for delivery of the chitosan-conjugated DNA construct. This is probably the first report on the delivery of nanoconjugated DNA construct in M. rosenbergii, against nodavirus.

  16. Lesotho: the politics of survival.

    Science.gov (United States)

    Lye, W F

    1982-01-01

    In this discussion of the politics of survival in Lesotho, attention is directed to the historical foundations; the road to dependency, the emergence of a political economy; and political transitions. The 1.25 million citizens of Lesotho enjoy a precarious independence. In November 1981, the government welcomed Russian military advisers. Presumably the reason for this was to help defend itself against the Republic of South Africa. This action was only the most recent of a series of increasingly hostile acts and verbal barrages which confirm the persistent aversion of Lesotho toward South Africa. The behavior contrasts markedly with an equally persistent pattern, that of continuous consultations between the Prime Minister of Lesotho since independence in 1966 and every leader of South Africa. The fact that some 200,000 Sotho workers, almost 1/6 of the nation's populaton, cross annually into South Africa to earn their only possible means of income lends a special character to this relationship. It reveals both the depth of Lesotho's aversion while equally affirming its reluctant dependence. It also illuminates a reciprocal need on the part of South Africa, which causes them to tolerate the irritant. The key to understanding the recent history of Lesotho lies with this fundamental interdependence and aversion. In the context of declining living standards at home and the demand for labor by South Africa, at first on the nearby farms and after 1867 in the mines and cities, Lesotho's economy became increasingly subject to political forces beyond its control. During even the early days of Moshoeshoe's reign, he encouraged youths to leave their families to obtain work among the aliens. His original objective was to have the youths learn useful new techniques which could be applied to enrich Lesotho beyond the few coins they might earn. The central focus of foreign employment before long became routine jobs in the mines. By the last decade of the 19th century, Lesotho

  4. Universality of Man as a Cultural and Historical Human Being

    Directory of Open Access Journals (Sweden)

    S. Z. Gontcharov

    2012-01-01

    Full Text Available On the grounds of theoretical synthesis, the paper reveals the phenomenon of human being in its creative dimension. The present research is aimed at exploring the prospective opportunities for academic processes. The basics of universal essence of man as a cultural historic being with unlimited potential of self- development are defined; the man being mirrored by the basic philosophic concepts: naturalistic, orthodox-oriented, bio-social or bio-socio-cultural. There are two opposing views on human nature: the anthropological essentialism holding that individuality is predetermined by essence; and the anthropological existentialism claiming the opposite – human existence precedes the essentiality, the latter being constituted by the acts of choice, self-development and self-responsibility for personal choice and projecting. In the first case, the subjective side of human existence is ignored, while in the second – the objective socially conditioned side is left behind. Both theories are antihistorical as it is the history that conditions the essence of man according to the ancestral determination, the latter being modified by way of human activity and communication in a particular historical period. The components of human universal essence are defined as follows: possession of organic body, social heritage, free will, self-activity, creativity, social and rational human nature, absence of antagonistic programs of social behavior. According to the author, for the adequate realization of human universality, it is necessary to move from the profit oriented speculative market economy to the creative one oriented on social effectiveness, quality of life and reproduction of wholesome individuals. The research output can be used for devising the methodology of philosophic and pedagogic anthropology, as well as pedagogic practices of teaching philosophy and pedagogic theory in higher school. 

  5. BurnMan: A lower mantle mineral physics toolkit

    KAUST Repository

    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.

  6. Adrenergic Modulation of Pancreatic Glucagon Secretion in Man

    Science.gov (United States)

    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

    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.

  8. Survival Strategies: LCTLs in Context

    Directory of Open Access Journals (Sweden)

    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.

  9. UV survival of human mycoplasmas

    International Nuclear Information System (INIS)

    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)

    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.

    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

    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.

    Integrated testing (such as Multi-Element Integrated Test (MEIT)) is critical to reducing risks and minimizing problems encountered during assembly, activation, and on-orbit operation of large, complex manned spacecraft. Provides the best implementation of "Test Like You Fly:. Planning for integrated testing needs to begin at the earliest stages of Program definition. Program leadership needs to fully understand and buy in to what integrated testing is and why it needs to be performed. As Program evolves and design and schedules mature, continually look for suitable opportunities to perform testing where enough components are together in one place at one time. The benefits to be gained are well worth the costs.

  4. A comparison of the radiological and chemical detriments in man

    International Nuclear Information System (INIS)

    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

    A survey of the currently available methods for the measurement of cerebral blood flow in man is given. Many of the clinically important brain diseases such as tumors, stroke, brain trauma or epilepsy entail focal or regional flow alterations. Therefore a special emphasis is placed on methods...... information both on spatial localization and, especially, on ischemic areas. The most promising is computer-assisted axial tomography with freely diffusible radioactive isotopes or with x-rays using an intra-arterial injection of contrast. But, the available techniques are still too slow: in order to measure...

    2006-01-01

    Full Text Available Renovascular hypertension occasionally manifests as an electrolyte disorder. The combination of hyponatremia and renovascular hypertension is known as hyponatremic-hypertensive syndrome. This syndrome was initially reported in children. Here, we describe a 45 year-old Saudi man who was admitted to the hospital with generalized body weakness and inability to walk. He was confused and was noted to have severe hypertension and very low serum sodium and potassium. The patient was recently started on captopril for blood pressure control, which was discontinued because of deterioration of renal function. Color Doppler renal ultrasound, and magnetic resonance angiography confirmed the diagnosis of renal artery stenosis.

    Galanin was infused intravenously into eight healthy volunteers at a dose of 40 pmol kg-1 min-1 for 1 h to investigate the pharmacological effects of this peptide on the postprandial sialagogical response in man. Galanin significantly increased the salivary volume and the saliva output of sodium, chloride and bicarbonate compared to control saline infusion, but had no effect on the output of potassium and alpha-amylase. An increase in salivary pH was also observed. The increase in salivary volume may indicate a physiological role of galanin in the control of salivary secretion. PMID:2485092

    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.

    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.

    International Nuclear Information System (INIS)

    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

    The resiliency and adaptive ability of microbial life in real time on Earth relies heavily upon horizontal gene transfer. Based on that knowledge, how likely is earth based microbial life to colonize extraterrestrial targets such as Mars? To address this question, we consider manned and unmanned space exploration, the resident microbiota that is likely to inhabit those vehicles, the adaptive potential of that microbiota in an extraterrestrial setting especially with regards to mobile genetic elements, and the likelihood that Mars like environments could initiate and sustain colonization.

    A 42-year-old man with a medical history of liver cirrhosis and portal hypertension was admitted to the hospital because of slowly progressive shortness of breath and hypoxemia. The diagnosis hepatopulmonary syndrome was confirmed by a pulmonary perfusion scan with 99m Tc-albumin. The scan showed a right-left shunt, because the 99m Tc-albumin transited the lungs and appeared in the brain, the thyroid gland, the kidneys and the spleen. The patient received a liver transplantation, which is considered the only definitive treatment. PMID:27484427

    Boyce, M J

    1982-09-01

    Data from pharmacological studies carried out in healthy subjects using systemic histamine or impromidine and their antagonists are reviewed. Exogenous histamine by rapid injection appears to stimulate only H1-receptors. Chlorpheniramine alone antagonised the responses to histamine. The effects of cardiovascular H2-receptor stimulation are demonstrated best by a sustained and large dose of histamine given by infusion. If it be considered desirable to antagonise all the cardiovascular responses to endogenous histamine, the available pharmacological data in man suggest this would be achieved best by a combination of an H1-and H2-receptor antagonist.

    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.

  2. A simple breath test for fat malabsorption in man

    International Nuclear Information System (INIS)

    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

    Ovarian cancer is the deadliest of all gynecologic cancers. Recent evidence demonstrates an association between enzymatic activity altering single nucleotide polymorphisms (SNP) with human cancer susceptibility. We sought to evaluate the association of SNPs in key oxidant and antioxidant enzymes with increased risk and survival in epithelial ovarian cancer. Individuals (n = 143) recruited were divided into controls, (n = 94): healthy volunteers, (n = 18), high-risk BRCA1/2 negative (n = 53), high-risk BRCA1/2 positive (n = 23) and ovarian cancer cases (n = 49). DNA was subjected to TaqMan SNP genotype analysis for selected oxidant and antioxidant enzymes. Of the seven selected SNP studied, no association with ovarian cancer risk (Pearson Chi-square) was found. However, a catalase SNP was identified as a predictor of ovarian cancer survival by the Cox regression model. The presence of this SNP was associated with a higher likelihood of death (hazard ratio (HR) of 3.68 (95% confidence interval (CI): 1.149-11.836)) for ovarian cancer patients. Kaplan-Meier survival analysis demonstrated a significant median overall survival difference (108 versus 60 months, pcancer patients, and thus may serve as a prognosticator.

    Full Text Available Infective endocarditis is defi ned as an infection of the endocardial surface of the heart. Its intracardiac effects include severe valvular insuffi ciency, which may lead to intractable congestive heart failure and myocardialabscesses. This disease still carries a poor prognosis and a high mortality.A severe case of infective endocarditis with its complications is presented. A man with aortic prosthetic valve due to earlier aortic stenosis and corrected aortal coarctation and implanted pacemaker presentedwith prolonged unexplained fever, malaise, sweating, weight loss (15 kg/4 months and lumbar pain.

  6. Analysis of success and survival in the health industry.

    Science.gov (United States)

    Simonetti, J L; Nykodym, N; Kubiak, S

    Modern management theory accepts that people work for many reasons and to fulfill many goals. People want to survive and succeed and, given the opportunity and the skills, they will. Health professionals seek some of the higher goals. They want to serve their fellow man without being a servant. They want to succeed by providing relief to the suffering; such success must, by necessity, be exceptionally sweet. When human lives are at stake, the word "important" is truly defined. To a health professional, advancement can be an organizational promotion or it can be a professional achievement. In either case, how he/she succeeds will depend on what he/she does. He/she must perform well against a yardstick that grows constantly due to the advances in medical science. He/she must also realize constantly that what he/she performs on is a human being, and must be treated as such. He/she must keep technically able without losing his/her ability to deal in human relations. This study has shown that the health professional accepts the importance of these concepts.

  7. Behavioural perspectives on piglet survival.

    Science.gov (United States)

    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

  8. The man-nature relationship and environmental ethics

    International Nuclear Information System (INIS)

    Our behaviour and policies with regard to nature and the environment should be guided by a code of ethics, which is to be derived from basic principles and from a pragmatic consideration of the issues at stake. The man-nature relationship has always been ambiguous, nature being seen as both a provider and an enemy. In the Judeo-Christian tradition, man is set apart from nature and called to dominate it, although this attitude has been revised to become one of stewardship. Oriental religions, on the other hand, have a more holistic view and consider humans as an integral part of nature. Modern philosophers have views ranging from anthropocentrism to biocentrism and egocentrism. It is suggested to take a pragmatic approach by which primary human needs are met first and foremost whereas the needs of other living organisms and ecosystems are allowed to prevail over secondary human needs. A plea is made to support the Earth Charter, which embodies in its principles and prescriptions a balanced respect for nature and future human generations

  9. Conceptual models in man-machine design verification

    International Nuclear Information System (INIS)

    The need for systematic methods for evaluation of design concepts for new man-machine systems has been rapidly increasing in consequence of the introduction of modern information technology. Direct empirical methods are difficult to apply when functions during rare conditions and support of operator decisions during emergencies are to be evaluated. In this paper, the problems of analytical evaluations based on conceptual models of the man-machine interaction are discussed, and the relations to system design and analytical risk assessment are considered. Finally, a conceptual framework for analytical evaluation is proposed, including several domains of description: 1. The problem space, in the form of a means-end hierarchy; 2. The structure of the decision process; 3. The mental strategies and heuristics used by operators; 4. The levels of cognitive control and the mechanisms related to human errors. Finally, the need for models representing operators' subjective criteria for choosing among available mental strategies and for accepting advice from intelligent interfaces is discussed

  10. Transfer of 137Cs through the food chain to man

    International Nuclear Information System (INIS)

    Deposition, concentrations in diet, and body burdens of 137Cs have been measured since 1954 at various sites throughout the world. This report is a compilation and updating of various fallout 137Cs measurements and an interpretation of transfer properties of 137Cs from deposition to diet and from diet to man. An empirical model is used to correlate deposition and diet data. Direct foliar contamination, stored food supplies, and uptake from soil contribute to the dietary levels of 137Cs. The accumulation of 137Cs by man is described by a single exponential model. The inferred biological half-times, 200 to 400 days, are somewhat greater than the half-time of about 100 days obtained from shorter term studies. Differences in body burdens due to sex, age, and weight are discussed. During the period 1954 to 1974, the internal dose from fallout 137Cs, based on average body burdens, is estimated to be 4 to 5 percent of the 21 year radiation dose from 40K

    Cooperation is the cornerstone of lion social behavior. In a notorious case, a coalition of two adult male lions from Tsavo, southern Kenya, cooperatively killed dozens of railway workers in 1898. The "man-eaters of Tsavo" have since become the subject of numerous popular accounts, including three Hollywood films. Yet the full extent of the lions' man-eating behavior is unknown; estimates range widely from 28 to 135 victims. Here we use stable isotope ratios to quantify increasing dietary specialization on novel prey during a time of food limitation. For one lion, the delta(13)C and delta(15)N values of bone collagen and hair keratin (which reflect dietary inputs over years and months, respectively) reveal isotopic changes that are consistent with a progressive dietary specialization on humans. These findings not only support the hypothesis that prey scarcity drives individual dietary specialization, but also demonstrate that sustained dietary individuality can exist within a cooperative framework. The intensity of human predation (up to 30% reliance during the final months of 1898) is also associated with severe craniodental infirmities, which may have further promoted the inclusion of unconventional prey under perturbed environmental conditions.

    1991-01-01

    In choosing an engine concept for the rocket vehicle to be used for the initial manned exploration of Mars, the two main factors in the decision should be what can be feasibly built and flight qualified within approximately the next 20 years, and what level of engine performance is required to safely perform these missions. In order to reduce the overall cost in developing this next generation space transportation system, it would be desirable to have a single engine design that could be used for a broad class of missions (for example, cargo and piloted lunar and Mars missions, orbit transfers around the Earth, and robotic missions to the planets). The engine thrust that is needed for manned Mars missions is addressed in this paper. We find that these missions are best served by a thrust level around 75,000 lbf to 100,000 lbf, and a thrust-to-engine weight ratio of about three. This thrust level might best be obtained by clustering five 15,000 lbf or 20,000 lbf engines. It may be better to throttle the engines back from full power between perigee burns, rather than shutting down. 5 refs., 4 figs.

  13. Two-phase deep-lung clearance in man

    International Nuclear Information System (INIS)

    For toxicological as well as physiological considerations, it is important to determine whether the long-term clearance of particles from the lungs of man takes place in more than one temporal subphase. Although long-term retention can be characterized with a single exponential, the existence of two distinct components would significantly alter estimates of overall residence times and hence potential effects of inhaled particulates. Physiological interpretations of the mechanisms of long-term particle clearance depend on the identification and quantification of such temporal subphases. A highly sensitive whole-body counter was used to measure the long-term retention of inhaled particles in man. After inhalation of 85Sr, lung retention was monitored in eight volunteers for periods ranging from 197 to 399 days. Their pulmonary-function values fell within normal limits, and they reported no symptoms of lung disease. Four of the individuals had never smoked, and four had not smoked for a minimum of 5 years. Single exponential representation half-times for the long-term retention were comparable between the two groups and were combined to give a mean half-time of 197 +- 32 days

  14. Uptake, retention and excretion of strontium in man

    International Nuclear Information System (INIS)

    The absorption of strontium from the gastrointestinal tract is discussed in relation to the diet and the different components of a bread-milk diet. A brief review is given of the results obtained by using chelators and diets high in calcium in order to decrease the strontium absorption. The ratios of strontium to calcium in the different body compartments for adult man is discussed. The results of recent experimental work on normal man on a constant diet, are reviewed with particular reference to the urinary excretion and the retention of Sr85 contained in the experimental diet. The endogenous faecal excretion is also derived. These results are compared with those obtained from a single intravenous injection of radioactive strontium. For all the subjects the retention was obtained from whole-body counting using a pulse height analyser. The retention of the strontium in the skeleton is analysed and it is postulated that there are at least three degrees of binding of radioactive strontium with bone. In particular the retention several months after the dose and the relationship of this retention to the radiation dose to the skeleton from Sr90 is discussed. A formula is proposed for the evaluation of body retention of a radioactive dose of strontium from the radioactivity excreted in the urine. (author)

  15. The man-nature relationship and environmental ethics.

    2004-01-01

    Our behaviour and policies with regard to nature and the environment should be guided by a code of ethics, which is to be derived from basic principles and from a pragmatic consideration of the issues at stake. The man-nature relationship has always been ambiguous, nature being seen as both a provider and an enemy. In the Judeo-Christian tradition, man is set apart from nature and called to dominate it, although this attitude has been revised to become one of stewardship. Oriental religions, on the other hand, have a more holistic view and consider humans as an integral part of nature. Modern philosophers have views ranging from anthropocentrism to biocentrism and egocentrism. It is suggested to take a pragmatic approach by which primary human needs are met first and foremost whereas the needs of other living organisms and ecosystems are allowed to prevail over secondary human needs. A plea is made to support the Earth Charter, which embodies in its principles and prescriptions a balanced respect for nature and future human generations. PMID:15162850

  17. Conceptual models in man-machine design verification

    International Nuclear Information System (INIS)

    The need for systematic methods for evaluation of design concepts for new man-machine systems has been rapidly increasing in consequence of the introduction of modern information technology. Direct empirical methods are difficult to apply when functions during rare conditions and support of operator decisions during emergencies are to be evaluated. In this paper, the problems of analytical evaluations based on conceptual models of the man-machine interaction are discussed, and the relations to system design and analytical risk assessment are considered. Finally, a conceptual framework for analytical evaluation is proposed, including several domains of description: 1. The problem space, in the form of a means-end hierarchy; 2. The structure of the decision process; 3. The mental strategies and heuristics used by operators; 3. The levels of cognitive control and the mechanisms related to human errors. Finally, the need for models representing operators' subjective criteria for choosing among available mental strategies and for accepting advice from intelligent interfaces is discussed. (author)

  18. The SysMan monitoring service and its management environment

    1996-06-01

    Management of modern information systems is becoming more and more complex. There is a growing need for powerful, flexible and affordable management tools to assist system managers in maintaining such systems. It is at the same time evident that effective management should integrate network management, system management and application management in a uniform way. Object oriented OSI management architecture with its four basic modelling concepts (information, organization, communication and functional models) together with widely accepted distribution platforms such as ANSA/CORBA, constitutes a reliable and modern framework for the implementation of a management toolset. This paper focuses on the presentation of concepts and implementation results of an object oriented management toolset developed and implemented within the framework of the ESPRIT project 7026 SysMan. An overview is given of the implemented SysMan management services including the System Management Service, Monitoring Service, Network Management Service, Knowledge Service, Domain and Policy Service, and the User Interface. Special attention is paid to the Monitoring Service which incorporates the architectural key entity responsible for event management. Its architecture and building components, especially filters, are emphasized and presented in detail.

  19. Selection of a Brine Processor Technology for NASA Manned Missions

    2016-01-01

    The current ISS Water Recovery System (WRS) reclaims water from crew urine, humidity condensate, and Sabatier product water. Urine is initially processed by the Urine Processor Assembly (UPA) which recovers 75% of the urine as distillate. The remainder of the water is present in the waste brine which is currently disposed of as trash on ISS. For future missions this additional water must be reclaimed due to the significant resupply penalty for missions beyond Low Earth Orbit (LEO). NASA has pursued various technology development programs for a brine processor in the past several years. This effort has culminated in a technology down-select to identify the optimum technology for future manned missions. The technology selection is based on various criteria, including mass, power, reliability, maintainability, and safety. Beginning in 2016 the selected technology will be transitioned to a flight hardware program for demonstration on ISS. This paper summarizes the technology selection process, the competing technologies, and the rationale for the technology selected for future manned missions.

    Two controlled trials were performed successively to evaluate the effect of high doses of oral pyridoxine on brain performance in man. In trial I, medical students volunteered to take 100 mg, 500 mg of pyridoxine a day or placebo for 10 days. A digit coding test was performed before, and at the end of the treatment period and a third 15 days later. The improvement of performance from the first to the third test (learning effect) was significantly better in the placebo group than in the B6 treated groups. This could be attributed to memorization of skills. Trial II was performed in obese patients starting a low calorie diet in whom vitamins are routinely prescribed. Performance in a work recognition test and in a visual retention test was lower for the group receiving 1 g of pyridoxine a day. Thus, high doses of oral pyridoxine are likely to impair memorization in man. Disturbances of neuro-transmitter metabolism such as increase of GABA production might explain the effect. As the benefit of high doses of pyridoxine has not been well-documented and as the study has suggested that undesired effects may indeed exist, the widespread use of such doses is questionable.

  1. Man-made objects cuing in satellite imagery

    2009-01-01

    We present a multi-scale framework for man-made structures cuing in satellite image regions. The approach is based on a hierarchical image segmentation followed by structural analysis. A hierarchical segmentation produces an image pyramid that contains a stack of irregular image partitions, represented as polygonized pixel patches, of successively reduced levels of detail (LOOs). We are jumping off from the over-segmented image represented by polygons attributed with spectral and texture information. The image is represented as a proximity graph with vertices corresponding to the polygons and edges reflecting polygon relations. This is followed by the iterative graph contraction based on Boruvka's Minimum Spanning Tree (MST) construction algorithm. The graph contractions merge the patches based on their pairwise spectral and texture differences. Concurrently with the construction of the irregular image pyramid, structural analysis is done on the agglomerated patches. Man-made object cuing is based on the analysis of shape properties of the constructed patches and their spatial relations. The presented framework can be used as pre-scanning tool for wide area monitoring to quickly guide the further analysis to regions of interest.

    Man-machine interaction is the gateway providing access to functions and services, which, due to the ever increasing complexity of smart systems, threatens to become a bottleneck. This book therefore introduces not only advanced interfacing concepts, but also gives insight into the related theoretical background.This refers mainly to the realization of video-based multimodal interaction via gesture, mimics, and speech, but also to interacting with virtual object in virtual environments, cooperating with local or remote robots, and user assistance. While most publications in the field of human factors engineering focus on interface design, this book puts special emphasis on implementation aspects. To this end it is accompanied by software development environments for image processing, classification, and virtual environment implementation. In addition a test data base is included for gestures, head pose, facial expressions, full-body person recognition, and people tracking. These data are used for the examples throughout the book, but are also meant to encourage the reader to start experimentation on his own. Thus the book may serve as a self-contained introduction both for researchers and developers of man-machine interfaces. It may also be used for graduate-level university courses. (orig.)

  4. Poor Man's Methadone: A Case Report of Loperamide Toxicity.

    2015-12-01

    Loperamide, a common over-the-counter antidiarrheal drug and opioid derivative, is formulated to act upon intestinal opioid receptors. However, at high doses, loperamide crosses the blood-brain barrier and reaches central opioid receptors in the brain, leading to central opiate effects including euphoria and respiratory depression. We report the case of a young man found dead in his residence with a known history of drug abuse. At autopsy, the only significant findings were a distended bladder and bloody oral purge. Drug screening found nontoxic levels of alprazolam, fluoxetine, and marijuana metabolites. Liquid chromatography time-of-flight mass spectrometry found an unusual set of split isotope peaks consistent with chlorine. On the basis of autopsy and toxicological findings, loperamide toxicity was suspected because of its opioid properties and molecular formula containing chlorine. A sample of loperamide was analyzed by liquid chromatography time-of-flight mass spectrometry, resulting in a matching mass and retention time to the decedent's sample. Subsequently, quantitative testing detected 63 ng/mL of loperamide or more than 6 times of therapeutic peak concentration. Cause of death was determined as "toxic effects of loperamide with fluoxetine and alprazolam." Because of its opioid effects and easy accessibility, loperamide is known as "poor man's methadone" and may go undetected at medical and forensic drug screening.

  5. Simulating statistics of lightning-induced and man made fires

    The frequency-area distributions of forest fires show power-law behavior with scaling exponents α in a quite narrow range, relating wildfire research to the theoretical framework of self-organized criticality. Examples of self-organized critical behavior can be found in computer simulations of simple cellular automata. The established self-organized critical Drossel-Schwabl forest fire model (DS-FFM) is one of the most widespread models in this context. Despite its qualitative agreement with event-size statistics from nature, its applicability is still questioned. Apart from general concerns that the DS-FFM apparently oversimplifies the complex nature of forest dynamics, it significantly overestimates the frequency of large fires. We present a straightforward modification of the model rules that increases the scaling exponent α by approximately 1•3 and brings the simulated event-size statistics close to those observed in nature. In addition, combined simulations of both the original and the modified model predict a dependence of the overall distribution on the ratio of lightning induced and man made fires as well as a difference between their respective event-size statistics. The increase of the scaling exponent with decreasing lightning probability as well as the splitting of the partial distributions are confirmed by the analysis of the Canadian Large Fire Database. As a consequence, lightning induced and man made forest fires cannot be treated separately in wildfire modeling, hazard assessment and forest management.

  12. Survival Processing and the Stroop Task

    Directory of Open Access Journals (Sweden)

    Stephanie A. Kazanas

    2015-11-01

    Full Text Available This study was designed to investigate the impact of survival processing with a novel task for this paradigm: the Stroop color-naming task. As the literature is mixed with regard to task generalizability, with survival processing promoting better memory for words, but not better memory for faces or paired associates, these types of task investigations are important to a growing field of research. Using the Stroop task provides a unique contribution, as identifying items by color is an important evolutionary adaptation and not specific to humans as is the case with word recall. Our results indicate that survival processing, with its accompanying survival-relevance rating task, remains the best mnemonic strategy for word memory. However, our results also indicate that presenting the survival passage does not motivate better color-naming performance than color-naming alone. In addition, survival processing led to a larger amount of Stroop interference, though not significantly larger than the other conditions. Together, these findings suggest that considering one’s survival when performing memory and attention-based tasks does not enhance cognitive performance generally, although greater allocation of attentional resources to color-incongruent concrete objects could be considered adaptive. These findings support the notion that engaging in deeper processing via survival-relevance ratings may preserve these words across a variety of experimental manipulations.

    Biofilters are widely adopted in Australia for stormwater treatment, but the reported removal of common faecal indicators (such as Escherichia coli (E. coli)) varies from net removal to net leaching. Currently, the underlying mechanisms that govern the faecal microbial removal in the biofilters are poorly understood. Therefore, it is important to study retention and subsequent survival of faecal microorganisms in the biofilters under different biofilter designs and operational characteristics. The current study investigates how E. coli survival is influenced by temperature, moisture content, sunlight exposure and presence of other microorganisms in filter media and top surface sediment. Soil samples were taken from two different biofilters to investigate E. coli survival under controlled laboratory conditions. Results revealed that the presence of other microorganisms and temperature are vital stressors which govern the survival of E. coli captured either in the top surface sediment or filter media, while sunlight exposure and moisture content are important for the survival of E. coli captured in the top surface sediment compared to that of the filter media. Moreover, increased survival was found in the filter media compared to the top sediment, and sand filter media was found be more hostile than loamy sand filter media towards E. coli survival. Results also suggest that the contribution from the tested environmental stressors on E. coli survival in biofilters will be greatly affected by the seasonality and may vary from one site to another.

    Full Text Available Background: During recent years, cardiopulmonary resuscitation (CPR in hospital has received much attention. However, the survival rate of CPR in Iran’s hospitals is unknown. This study was designed to evaluate outcome of in-hospital CPR in Kashan. Methods: A longitudinal case registry study was conducted on all cases of in-hospital CPR during 6 months at 2002. Necessary data including; age, sex, underlying disease, working shift, time from cardiac arrest until initiating of CPR and until defibrillation, duration and result of CPR, frequency of tracheal intubations and time served for it were collected in a checklist. Results: In six months study, 206 cases of cardiopulmonary resuscitation attempted. The survival rate was similar for both sexes. Short-term survival observed in19.9% of cases and only 5.3% survived to discharge. Conclusions: Duration of CPR, time of the first defibrillation, response time and the location of cardiac arrest are the key predictors of survival to hospital discharge and in-hospital CPR strategies require improvement. This study promotes a national study on post CPR survival for accurate data on our performance in attention to chain of survival. KeyWords: Cardiopulmonary Resuscitation (CPR, Survival rate, Iran

    2006-09-01

    This is the story of Rupert T. Gould (1890-1948), the polymath and horologist. A remarkable man, Lt Cmdr Gould made important contributions in an extraordinary range of subject areas throughout his relatively short and dramatically troubled life. From antique clocks to scientific mysteries, from typewriters to the first systematic study of the Loch Ness Monster, Gould studied and published on them all. With the title The Stargazer, Gould was an early broadcaster on the BBC's Children's Hour when, with his encyclopaedic knowledge, he became known as The Man Who Knew Everything. Not surprisingly, he was also part of that elite group on BBC radio who formed The Brains Trust, giving on-the-spot answers to all manner of wide ranging and difficult questions. With his wide learning and photographic memory, Gould awed a national audience, becoming one of the era's radio celebrities. During the 1920s Gould restored the complex and highly significant marine timekeepers constructed by John Harrison (1693-1776), and wrote the unsurpassed classic, The Marine Chronometer, its History and Development . Today he is virtually unknown, his horological contributions scarcely mentioned in Dava Sobel's bestseller Longitude. The TV version of Longitude, in which Jeremy Irons played Rupert Gould, did at least introduce Gould's name to a wider public. Gould suffered terrible bouts of depression, resulting in a number of nervous breakdowns. These, coupled with his obsessive and pedantic nature, led to a scandalously-reported separation from his wife and cost him his family, his home, his job, and his closest friends. In this first-ever biography of Rupert Gould, Jonathan Betts, the Royal Observatory Greenwich's Senior Horologist, has given us a compelling account of a talented but flawed individual. Using hitherto unknown personal journals, the family's extensive collection of photographs, and the polymath's surviving records and notes, Betts tells the story of how Gould's early life, his

    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.

    Poult survival is key to understanding annual change in wild turkey (Meleagris gallopavo) populations. Survival of eastern wild turkey poults (M. g. silvestris) 0-4 weeks posthatch was studied in southcentral Iowa during 1994-97. Survival estimates of poults were calculated based on biweekly flush counts and daily locations acquired via radiotelemetry. Poult survival averaged 0.52 ?? 0.14% (?? ?? SE) for telemetry counts and 0.40 ?? 0.15 for flush counts. No within-year or across-year differences were detected between estimation techniques. More than 72% (n = 32) of documented poult mortality occurred ???14 days posthatch, and mammalian predation accounted for 92.9% of documented mortality. If mortality agents are not of concern, we suggest biologists conduct 4-week flush counts to obtain poult survival estimates for use in population models and development of harvest recommendations.
