    Obesity is undoubtedly one of the biggest medical problems of the 21st century. Regrettably, the problem affects more and more children and adolescents. 10% of world's school-aged children have an excess body weight and a quarter of these children are obese. In Europe every fifth school-aged child suffers from an excess body weight. The prevalence of overweight and obesity among Polish adolescents is about 14%. An excess body weight can be the consequence of genetic factors, endocrine disorders or certain drugs. However, "simple obesity" is the most common, consequence of providing too much energy from food products in comparison to energy expenditure (caloric excess). Today's lifestyle promotes the development of obesity. The lack of physical activity, sedentary lifestyle and energy-rich diet are the main causes of an excess body fat accumulation. Because of improper eating behaviours children consume an excess amount of energy; and their diet is deficient in elements necessary for proper development. The examples of such bad eating habits are: snacking highly processed and calorie-rich foods between meals eating in front of the TV screen, skipping breakfasts, drinking sugar-sweetened beverages, "eating out" frequently and "emotional eating". Bad eating behaviours are crucial factors for the development of obesity. Eating habits are usually formed in early childhood and parents play a very important role in their development.

    This short paper reports on a workshop held in Horw, Switzerland, on the application potential of low-temperature fuel cells. It looks at the increasing interest in small, electrically-driven boats in Europe and, in particular, at the option of powering them with fuel cells. A prototype implementation of a test boat is described. Powered by a 300-watt portable PEFC fuel cell constructed by the Paul Scherrer Institute (PSI) and the University of Applied Science in Solothurn, Switzerland, the boat is part of a project to study the technical feasibility of such drive systems for leisure craft and small boats. The paper addresses hydrogen security questions, energy-efficient drives and controllers, maintenance questions and discusses if a combination of fuel cells and photovoltaics would be viable. Also, the design of the boat's hull and the propellers that are used are looked at critically. The economic viability of fuel-cell powered boats is examined. The authors state that they are convinced that such fuel cell drives could be commercially interesting for larger passenger boats, too.

    Scrutinizing title of the new material composition is the bottleneck in our composition teaching.According to the sample coil,we can see that the mistake of students' scrutinizing title lies in that they don't have good thinking habit,which is mainly manifested as following:associating old materials because of their preconceived ideas;having partial thinking and lacking systematic view of thinking;lacking guiding process and showing the thinking point directly;not very good at taking down intuitive thinking in scratch paper.What we can do in our composition teaching is to take countermeasures so as to help the students form good thinking habit and efficiently improve the average scores in Chinese examination.%新材料作文的审题,是我们作文教学中的瓶颈。样卷显示,学生审题错误在于没有形成良好的思维习惯。主要表现为:联想旧材料,思维出现先入为主;出现局部性思维,缺少系统思维观;缺乏导引性思维过程,直接展现思维观点;不善于用草稿纸记直觉思维。在作文教学中我们应采取应对措施,让学生养成良好的审题思维习惯,有效提高语文的平均分。

    Full Text Available Habitable Trinity is a newly proposed concept of a habitable environment. This concept indicates that the coexistence of an atmosphere (consisting largely of C and N, an ocean (H and O, and a landmass (supplier of nutrients accompanying continuous material circulation between these three components driven by the Sun is one of the minimum requirements for life to emerge and evolve. The life body consists of C, O, H, N and other various nutrients, and therefore, the presence of water, only, is not a sufficient condition. Habitable Trinity environment must be maintained to supply necessary components for life body. Our Habitable Trinity concept can also be applied to other planets and moons such as Mars, Europa, Titan, and even exoplanets as a useful index in the quest for life-containing planetary bodies.

    2016-10-01

    The ratio of bad habits, mouth breathing and malocclusion is an important issue in view of prevention and early treatment of disorders of the craniofacial growth. While bad habits can interfere with the position of the teeth and normal pattern of skeletal growth, on the other hand obstruction of the upper airway, resulting in mouth breathing, changes the pattern of craniofacial growth causing malocclusion. Our crosssectional study, carried out on 3017 children using the ROMA index, was developed to verify if there was a significant correlation between bad habits/mouth breathing and malocclusion. The results showed that an increase in the degree of the index increases the prevalence of bad habits and mouth breathing, meaning that these factors are associated with more severe malocclusions. Moreover, we found a significant association of bad habits with increased overjet and openbite, while no association was found with crossbite. Additionally, we found that mouth breathing is closely related to increased overjet, reduced overjet, anterior or posterior crossbite, openbite and displacement of contact points. Therefore, it is necessary to intervene early on these aetiological factors of malocclusion to prevent its development or worsening and, if already developed, correct it by early orthodontic treatment to promote eugnatic skeletal growth.

  9. A fuzzy 'boater' model to detect fouling and spreading risk of non-indigenous species by recreational boats.

    Science.gov (United States)

    Ferrario, Jasmine; Marchini, Agnese; Borrelli, Paola; Gigli Berzolari, Francesca; Occhipinti-Ambrogi, Anna

    2016-11-01

    Recreational boating is an unregulated and underestimated vector of spread of non-indigenous species (NIS) in marine environments. The risk of a single boat to spread NIS depends not only on the local environmental context, but also on the type of boat and on the boat owner's behaviour (hull cleaning and painting frequency, travel history). In this paper we present a model to assess the risk of fouling and spreading of NIS and its application to data derived from a questionnaire given to Italian boat owners. The model uses a two-levels fuzzy logic approach: (1) the first level assesses the risk of hull fouling and risk of spreading separately; (2) the second level combines the two separate risks in an overall index ranging from 0 (null risk) to 100 (highest risk) and measures the global risk of NIS introduction and spread through recreational boating. The questionnaire and the fuzzy model allow for a simple and rapid assessment of boats most likely to be infested. The proposed fuzzy model can be easily edited and adapted to context-specific ecological and social conditions. The results of this Italian study showed that 53.9% of the respondents were in the very-low and low risk categories, and 46.1% in the medium, high and very-high risk categories. Possible associations between some boaters habits and the fouling and spreading risk were explored using logistic regression analyses. The results indicate a high-risk profile of boat owner as an experienced sailor who visits many marinas during the summer season. Biosecurity guidelines, containment measures and awareness raising programmes should be implemented to prevent and avoid further spread of NIS in marine environments, and such management actions would benefit from the early detection of high-risk boats, and from the identification of profiles of boaters upon which these initiatives should be prioritized.

  10. Swiss fuel cell passenger and pleasure boats

    Energy Technology Data Exchange (ETDEWEB)

    Affolter, J.-F.

    2000-07-01

    This paper published by the University of Applied Science in Yverdon-les-Bains, Switzerland, looks at the development of electrically driven small boats that are powered by fuel cells. The various implementations of the test boats are described. Starting with a 100-watt PEM fuel cell built by the Paul Scherrer Institute (PSI) and the University of Applied Science in Solothurn, Switzerland, for educational purposes, a small pedal-boat was electrified. The paper describes the development of four further prototypes and introduces a new project for a 6-passenger leisure boat powered by a 2 kW PEFC fuel cell. Apart from the fuel cells, various other components such as propellers and control electronics are discussed as are the remaining problems still to be solved before the cells and boats can be marketed. Since they were carried out at a technical university, these projects are said to have provided an excellent way of teaching new technologies to students.

    The search for exoplanets includes the promise to eventually find and identify habitable worlds. The thousands of known exoplanets and planet candidates are extremely diverse in terms of their masses or sizes, orbits, and host star type. The diversity extends to new kinds of planets, which are very common yet have no solar system counterparts. Even with the requirement that a planet's surface temperature must be compatible with liquid water (because all life on Earth requires liquid water), a new emerging view is that planets very different from Earth may have the right conditions for life. The broadened possibilities will increase the future chances of discovering an inhabited world.

  3. Eggs: good or bad?

    Science.gov (United States)

    Griffin, Bruce A

    2016-08-01

    Eggs have one of the lowest energy to nutrient density ratios of any food, and contain a quality of protein that is superior to beef steak and similar to dairy. From a nutritional perspective, this must qualify eggs as 'good'. The greater burden of proof has been to establish that eggs are not 'bad', by increasing awareness of the difference between dietary and blood cholesterol, and accumulating sufficient evidence to exonerate eggs from their associations with CVD and diabetes. After 60 years of research, a general consensus has now been reached that dietary cholesterol, chiefly from eggs, exerts a relatively small effect on serum LDL-cholesterol and CVD risk, in comparison with other diet and lifestyle factors. While dietary guidelines have been revised worldwide to reflect this view, associations between egg intake and the incidence of diabetes, and increased CVD risk in diabetes, prevail. These associations may be explained, in part, by residual confounding produced by other dietary components. The strength of evidence that links egg intake to increased CVD risk in diabetes is also complicated by variation in the response of serum LDL-cholesterol to eggs and dietary cholesterol in types 1 and 2 diabetes. On balance, the answer to the question as to whether eggs are 'bad', is probably 'no', but we do need to gain a better understanding of the effects of dietary cholesterol and its association with CVD risk in diabetes.

    2015-12-01

    Based on the recently proposed Chinese ischemic stroke subclassification (CISS) system, intracranial branch atheromatous disease (BAD) is divided into large artery atherosclerosis (LAA) and penetrating artery disease (PAD). In the current retrospective analysis, we compared the general characteristics of BAD-LAA with BAD-PAD, BAD-LAA with non-BAD-LAA and BAD-PAD with non-BAD-PAD. The study included a total of 80 cases, including 45 cases of BAD and 35 cases of non-BAD. Subjects were classified using CISS system: BAD-LAA, BAD-PAD, non-BAD-LAA and non-BAD-PAD. In addition to analysis of general characteristics, the correlation between the factors and the two subtypes of BAD was evaluated. The number of cases included in the analysis was: 32 cases of BAD-LAA, 13 cases of BAD-PAD, 21 cases of non-BAD-LAA, and 14 cases of non-BAD-PAD. Diabetes mellitus affected more non-BAD-LAA patients than BAD-LAA patients (P=0.035). In comparison with non-BAD-PAD, patients with BAD-PAD were younger (P=0.040), had higher initial NIHSS score (PBAD, the PAD subtype was associated with smoking (OR=0.043; P=0.011), higher low-density lipoprotein (OR=5.339; P=0.029), ischemic heart disease (OR=9.383; P=0.047) and diabetes mellitus (OR=12.59; P=0.020). It was concluded that large artery atherosclerosis was the primary mechanism of BAD. The general characteristics showed no significant differences between the CISS subtypes of LAA and PAD within BAD, as well as between the BAD and non-BAD within LAA subtype. Several differences between PAD subtypes of BAD and non-BAD were revealed.

  7. Bad Astronomy Goes Hollywood

    Science.gov (United States)

    Plait, P.

    2003-05-01

    It can be argued that astronomy is the oldest of all the sciences, so you'd think that after all this time people would have a pretty good understanding of it. In reality, however, misconceptions about astronomy abound, and even basic concepts are misunderstood. There are many sources of these cosmic misconceptions, including incorrect textbooks, parents and/or teachers who don't understand astronomy and therefore spread misinformation, urban legends, and so on. Perhaps the most pervasive source of bad astronomy is Hollywood. Science fiction movies are enormously popular, but are commonly written and directed by people who don't have even a passing familiarity with astronomy. The smash hit "Armageddon" (the number one box office movie of 1998), for example, used vast quantities of incorrect astronomy in the plot. It reinforced such popular misconceptions as huge asteroids impacting the Earth with little warning, small meteorites being hot when they impact, air existing in space, and that a simple bomb can blow up an asteroid the size of a small moon (even when the bomb is buried only 800 feet deep!). However, movie scenes can be used as a hook that engages the student, helping them learn and remember the correct science. In this talk, I will light-heartedly discuss specific examples of common misinformation, using movie clips, diagrams, and a splash of common sense to show just where Hollywood gets it wrong, and what you can do to help students and the public get it right.

    2016-01-01

    As the proverbial creatures of habit, people tend to repeat the same behaviors in recurring contexts. This review characterizes habits in terms of their cognitive, motivational, and neurobiological properties. In so doing, we identify three ways that habits interface with deliberate goal pursuit: First, habits form as people pursue goals by repeating the same responses in a given context. Second, as outlined in computational models, habits and deliberate goal pursuit guide actions synergistically, although habits are the efficient, default mode of response. Third, people tend to infer from the frequency of habit performance that the behavior must have been intended. We conclude by applying insights from habit research to understand stress and addiction as well as the design of effective interventions to change health and consumer behaviors.

    2005-06-01

    The present research investigated the mechanisms guiding habitual behavior, specifically, the stimulus cues that trigger habit performance. When usual contexts for performance change, habits cannot be cued by recurring stimuli, and performance should be disrupted. Thus, the exercising, newspaper reading, and TV watching habits of students transferring to a new university were found to survive the transfer only when aspects of the performance context did not change (e.g., participants continued to read the paper with others). In some cases, the disruption in habits also placed behavior under intentional control so that participants acted on their current intentions. Changes in circumstances also affected the favorability of intentions, but changes in intentions alone could not explain the disruption of habits. Furthermore, regardless of whether contexts changed, nonhabitual behavior was guided by intentions.

  4. Radio-controlled boat for measuring water velocities and bathymetry

    Science.gov (United States)

    Vidmar, Andrej; Bezak, Nejc; Sečnik, Matej

    2016-04-01

    Radio-controlled boat named "Hi3" was designed and developed in order to facilitate water velocity and bathymetry measurements. The boat is equipped with the SonTek RiverSurveyor M9 instrument that is designed for measuring open channel hydraulics (discharge and bathymetry). Usually channel cross sections measurements are performed either from a bridge or from a vessel. However, these approaches have some limitations such as performing bathymetry measurements close to the hydropower plant turbine or downstream from a hydropower plant gate where bathymetry changes are often the most extreme. Therefore, the radio-controlled boat was designed, built and tested in order overcome these limitations. The boat is made from a surf board and two additional small balance support floats. Additional floats are used to improve stability in fast flowing and turbulent parts of rivers. The boat is powered by two electric motors, steering is achieved with changing the power applied to left and right motor. Furthermore, remotely controlled boat "Hi3" can be powered in two ways, either by a gasoline electric generator or by lithium batteries. Lithium batteries are lighter, quieter, but they operation time is shorter compared to an electrical generator. With the radio-controlled boat "Hi3" we can perform measurements in potentially dangerous areas such as under the lock gates at hydroelectric power plant or near the turbine outflow. Until today, the boat "Hi3" has driven more than 200 km in lakes and rivers, performing various water speed and bathymetry measurements. Moreover, in future development the boat "Hi3" will be upgraded in order to be able to perform measurements automatically. The future plans are to develop and implement the autopilot. With this approach the user will define the route that has to be driven by the boat and the boat will drive the pre-defined route automatically. This will be possible because of the very accurate differential GPS from the Sontek River

    The relative importance of multiple vectors to the initial establishment, spread and population dynamics of invasive species remains poorly understood. This study used molecular methods to clarify the roles of commercial shipping and recreational boating in the invasion by the cosmopolitan tunicate, Botryllus schlosseri. We evaluated (i) single vs. multiple introduction scenarios, (ii) the relative importance of shipping and boating to primary introductions, (iii) the interaction between these vectors for spread (i.e. the presence of a shipping-boating network) and (iv) the role of boating in determining population similarity. Tunicates were sampled from 26 populations along the Nova Scotia, Canada, coast that were exposed to either shipping (i.e. ports) or boating (i.e. marinas) activities. A total of 874 individuals (c. 30 per population) from five ports and 21 marinas was collected and analysed using both mitochondrial cytochrome c oxidase subunit I gene (COI) and 10 nuclear microsatellite markers. The geographical location of multiple hotspot populations indicates that multiple invasions have occurred in Nova Scotia. A loss of genetic diversity from port to marina populations suggests a stronger influence of ships than recreational boats on primary coastal introductions. Population genetic similarity analysis reveals a dependence of marina populations on those that had been previously established in ports. Empirical data on marina connectivity because of boating better explains patterns in population similarities than does natural spread. We conclude that frequent primary introductions arise by ships and that secondary spread occurs gradually thereafter around individual ports, facilitated by recreational boating.

    The pedodontic admission histories of 1600 Mexican children were analyzed, to determine general epidemiologic factors or oral habits, as well as their relationship with identifiable biopsychosociologic factors. Fifty-six percent of the children gave evidence of an oral habit, with significant predisposition among female patients, single children, subjects in poor physical health (particularly from allergies), as well as children with histories of chronic health problems. Oral habits should be considered a major health hazard because of their high incidence. Successful treatment requires a multidisciplinary approach to the basic cause of the problem.

  11. Automatic Boat Identification System for VIIRS Low Light Imaging Data

    Directory of Open Access Journals (Sweden)

    Christopher D. Elvidge

    2015-03-01

    Full Text Available The ability for satellite sensors to detect lit fishing boats has been known since the 1970s. However, the use of the observations has been limited by the lack of an automatic algorithm for reporting the location and brightness of offshore lighting features arising from boats. An examination of lit fishing boat features in Visible Infrared Imaging Radiometer Suite (VIIRS day/night band (DNB data indicates that the features are essentially spikes. We have developed a set of algorithms for automatic detection of spikes and characterization of the sharpness of spike features. A spike detection algorithm generates a list of candidate boat detections. A second algorithm measures the height of the spikes for the discard of ionospheric energetic particle detections and to rate boat detections as either strong or weak. A sharpness index is used to label boat detections that appear blurry due to the scattering of light by clouds. The candidate spikes are then filtered to remove features on land and gas flares. A validation study conducted using analyst selected boat detections found the automatic algorithm detected 99.3% of the reference pixel set. VIIRS boat detection data can provide fishery agencies with up-to-date information of fishing boat activity and changes in this activity in response to new regulations and enforcement regimes. The data can provide indications of illegal fishing activity in restricted areas and incursions across Exclusive Economic Zone (EEZ boundaries. VIIRS boat detections occur widely offshore from East and Southeast Asia, South America and several other regions.

    During 1988 to 1989 the NASA/USRA Advanced Design Program sponsored research and design efforts aimed at developing habitability criteria and at defining a habitability concept as a useful tool in understanding and evaluating dwellings for prolonged stays in extraterrestrial space. The Circulating Auto sufficient Mars-Earth Luxurious Orbital Transport (CAMELOT) was studied as a case in which the students would try to enhance the quality of life of the inhabitants by applying architectural design methodology. The study proposed 14 habitability criteria considered necessary to fulfill the defined habitability concept, which is that state of equilibrium that results from the interaction between components of the Individual Architecture Mission Complex, which allows a person to sustain physiological homeostatis, adequate performance, and acceptable social relationships. Architecture, design development, refinements and revisions to improve the quality of life, new insights on artificial gravity, form and constitution problems, and the final design concept are covered.

    Oral habits, if persist beyond certain developmental age, can pose great harm to the developing teeth, occlusion, and surrounding oral tissues. In the formative years, almost all children engage in some non-nutritive sucking habits. Clinicians, by proper differential diagnosis and thorough understanding of natural growth and developmental processes, should take a decision for intervening. This article describes case series reports of thumb sucking, finger sucking, and tongue thrusting habits, which have been successfully treated by both removable and fixed orthodontic appliances. The cases shown are ranging from the age group of 9-19 years presenting combination of both mixed and permanent dentition development. All cases show satisfactory correction of habits and stable results.

    Directory of Open Access Journals (Sweden)

    Monica R. F Hilário

    2008-12-01

    Full Text Available The neural circuits involved in learning and executing goal-directed actions, which are governed by action-outcome contingencies and sensitive to changes in the expected value of the outcome, have been shown to be different from those mediating habits, which are less dependent on action-outcome relations and changes in outcome value. Extended training, different reinforcement schedules, and substances of abuse have been shown to induce a shift from goal-directed performance to habitual performance. This shift can be beneficial in everyday life, but can also lead to loss of voluntary control and compulsive behavior, namely during drug seeking in addiction. Although the brain circuits underlying habit formation are becoming clearer, the molecular mechanisms underlying habit formation are still not understood. Here, we review a recent study where Hilario et al. established behavioral procedures to investigate habit formation in mice in order to investigate the molecular mechanisms underlying habit formation. Using those procedures, and a combination of genetic and pharmacological tools, the authors showed that endocannabinoid signaling is critical for habit formation.

  2. Flight of the loon : solar-powered boating

    2006-04-01

    Details of the first solar-powered, zero-emission boat to venture across the Trent-Severn waterway were presented. Called the 'Loon', the boat is now being manufactured for environmentally-conscious boaters around the world. The seating arrangement, pontoon design, and propulsion system were all designed to minimize impacts on the ecosystem. A prototype boat was built and tested in the summer of 2005 to determine the viability of the solar-powered boat, and a family trip down the waterway was completed in August. Results of the trip encouraged the inventor to raise capital and a suitable production facility. After several months of development, the first production boat was completed with many improvements to the original prototype. An entrepreneur from Belize was the first person to place an order after he discovered that most commercially-available solar-powered boats were higher-priced and less capable than the Loon. High gas prices and the detrimental effects of fuel exhaust in lakes have caused many people to become sensitive to the issues surrounding fuel use and pleasure boats. It was concluded that a storefront has recently been opened north of Orillia in order to sell the solar-powered craft. 3 figs.

  7. Age aspects of habitability

    Science.gov (United States)

    Safonova, M.; Murthy, J.; Shchekinov, Yu. A.

    2016-04-01

    A `habitable zone' of a star is defined as a range of orbits within which a rocky planet can support liquid water on its surface. The most intriguing question driving the search for habitable planets is whether they host life. But is the age of the planet important for its habitability? If we define habitability as the ability of a planet to beget life, then probably it is not. After all, life on Earth has developed within only ~800 Myr after its formation - the carbon isotope change detected in the oldest rocks indicates the existence of already active life at least 3.8 Gyr ago. If, however, we define habitability as our ability to detect life on the surface of exoplanets, then age becomes a crucial parameter. Only after life had evolved sufficiently complex to change its environment on a planetary scale, can we detect it remotely through its imprint on the atmosphere - the so-called biosignatures, out of which the photosynthetic oxygen is the most prominent indicator of developed (complex) life as we know it. Thus, photosynthesis is a powerful biogenic engine that is known to have changed our planet's global atmospheric properties. The importance of planetary age for the detectability of life as we know it follows from the fact that this primary process, photosynthesis, is endothermic with an activation energy higher than temperatures in habitable zones, and is sensitive to the particular thermal conditions of the planet. Therefore, the onset of photosynthesis on planets in habitable zones may take much longer time than the planetary age. The knowledge of the age of a planet is necessary for developing a strategy to search for exoplanets carrying complex (developed) life - many confirmed potentially habitable planets are too young (orbiting Population I stars) and may not have had enough time to develop and/or sustain detectable life. In the last decade, many planets orbiting old (9-13 Gyr) metal-poor Population II stars have been discovered. Such planets had had

    Many individuals around the world follow vegetarian diet. The aim of this study was to examine the variables associated to a vegetarian diet. Data were drawn from the national cross-sectional survey "Health and use of health care in Italy". Vegetarian habit was prevalent in 0.79% of sample, mainly females. Multivariate model has confirmed the association between vegetarianism and females, age, level of education, marital status separated/divorced/single, diabetes, bad state of perceived health. Little to no research has been conducted in this area until now. As for all types of diet, the vegetarian one should be controlled.

  5. Good and Bad Sleep in Childhood: A Questionnaire Survey amongst School Children in Southern Italy

    2011-01-01

    Full Text Available Despite its clinical importance, the issue of subjective sleep quality in children remains unexplored. Here we investigate, in school-aged children, the prevalence of bad sleep perception and its relationships with sleep habits and daytime functioning, to provide hints on its possible determinants. Subjective sleep perception, sleep habits, and daytime functioning were studied through a questionnaire survey in a sample of 482 children (6–12 yrs.. Being “bad sleeper” was reported by 6.9% of the sample. Compared to the “good sleepers”, these subjects displayed shorter sleep duration on schooldays, longer sleep latencies, and a more pronounced evening preference, beyond more frequent insufficient sleep. Though no differences emerged in sleepiness, bad sleepers showed higher impairments in daytime functioning, indicated by more frequent depressed mood and impulsivity. These distinctive features might be very important to precociously detect those children who are possibly more vulnerable to sleep disturbances and whose sleep-wake rhythms evolution should be paid particular attention thereafter.

  6. Biofouling of leisure boats as a source of metal pollution.

    2017-01-01

    The release of harmful metals from antifouling paints to water bodies is a well-known problem. In this study, we measured both the amount of biofouling growth on leisure boats during one season as well as the concentration of metals accumulated by the biofouling matrix. Furthermore, the efficiency of antifouling paints and mechanical boat cleaning as well as the effect of hull colour on biofouling were evaluated. Unlike paint residues, biofouling waste has never been regarded as a source of metal contamination and has previously been neglected in the scientific literature. Our results revealed that the biofouling waste contained very high concentrations of metals, up to 28,000 mg copper/kg dw and 171,000 mg zinc/kg dw, which exceeds the guidance values for least sensitive land use in Sweden by factors of 140 and 340, respectively. This observation is important because the contaminated biofouling waste is commonly disposed of in boatyard soils at the end of each season, thus increasing the levels of metal pollution. Moreover, there was no significant difference in the amount of biofouling if the boats were coated with copper or zinc containing paints or no paint at all, indicating that biocide paints might not be necessary in low-salinity areas such as the Stockholm archipelago. For boats that were not painted at all during the season, those washed on boat washers (mechanically) had on average half of the amount of biofouling compared to boats that were not cleaned mechanically. The results of the study indicate the importance of proper management of biofouling waste as well as the use of more environmentally friendly removal methods for biofouling such as boat washers.

  7. The Habitable Zone Gallery

    2012-01-01

    The Habitable Zone Gallery (www.hzgallery.org) is a new service to the exoplanet community which provides Habitable Zone (HZ) information for each of the exoplanetary systems with known planetary orbital parameters. The service includes a sortable table with information on the percentage of orbital phase spent within the HZ, planetary effective temperatures, and other basic planetary properties. In addition to the table, we also plot the period and eccentricity of the planets with respect to their time spent in the HZ. The service includes a gallery of known systems which plot the orbits and the location of the HZ with respect to those orbits. Also provided are animations which aid in orbit visualization and provide the changing effective temperature for those planets in eccentric orbits. Here we describe the science motivation, the under-lying calculations, and the structure of the web site.

  8. Pathways Towards Habitable Moons

    2009-01-01

    The search for life outside of the Solar System should not be restricted to exclusively planetary bodies; large moons of extrasolar planets may also be common habitable environments throughout the Galaxy. Extrasolar moons, or exomoons, may be detected through transit timing effects induced onto the host planet as a result of mutual gravitational interaction. In particular, transit timing variations (TTV) and transit duration variations (TDV) are predicted to produce a unique exomoon signature, which is not only easily distinguished from other gravitational perturbations, but also provides both the period and mass of an exomoon. Using these timing effects, photometry greater or equal to that of the Kepler Mission is readily able to detect habitable-zone exomoons down to 0.2 Earth masses and could survey up to 25,000 stars for 1 Earth-mass satellites. We discuss future possibilities for spectral retrieval of such bodies and show that transmission spectroscopy with JWST should be able to detect molecular species...

Set that the nutrition of the majority of students is irrational, in the daily life of young people there is a number of risk factors associated with inadequate intake of healthy food products. Have far-reaching enough food habits due to the consumption of so-called "food waste". The analysis of the correlation relationship between nutrition, mental performance and lifestyle factors, confirmed that a violation of the rules of a healthy diet affects the performance efficiency, increases the likelihood of bad habits. Slow food culture, lack of knowledge of young people on healthy food cause the need for appropriate health education.

    Why do we repeat choices that we know are bad for us? Decision making is characterized by the parallel engagement of two distinct systems, goal-directed and habitual, thought to arise from two computational learning mechanisms, model-based and model-free. The habitual system is a candidate source of pathological fixedness. Using a decision task that measures the contribution to learning of either mechanism, we show a bias towards model-free (habit) acquisition in disorders involving both natural (binge eating) and artificial (methamphetamine) rewards, and obsessive-compulsive disorder. This favoring of model-free learning may underlie the repetitive behaviors that ultimately dominate in these disorders. Further, we show that the habit formation bias is associated with lower gray matter volumes in caudate and medial orbitofrontal cortex. Our findings suggest that the dysfunction in a common neurocomputational mechanism may underlie diverse disorders involving compulsion.

  11. Effective Physics Study Habits

    2011-04-01

    We discuss the methods of efficient study habits and how they can be used by students to help them improve learning physics. In particular, we deal with ideas pertaining to the most effective techniques needed to help students improve their physics study skills. These ideas were developed as part of Project IMPACTSEED (IMproving Physics And Chemistry Teaching in SEcondary Education), an outreach grant funded by the Alabama Commission on Higher Education. This project is motivated by a major pressing local need: A large number of high school physics teachers teach out of field. In the presentation, focus on topics such as the skills of how to develop long term memory, how to improve concentration power, how to take class notes, how to prepare for and take exams, how to study scientific subjects such as physics. We argue that the student who conscientiously uses the methods of efficient study habits will be able to achieve higher results than the student who does not; moreover, a student equipped with the proper study skills will spend much less time to learn a subject than a student who has no good study habits. The underlying issue here is not the quantity of time allocated to the study efforts by the student, but the efficiency and quality of actions. This work is supported by the Alabama Commission on Higher Education as part of IMPACTSEED grant.

    2014-01-01

    Stephen Crane is one of the greatest figures in the history of American literature and his novella The Open Boat is wide-ly known by people all over the world as a representative work of Naturalism. This paper aims at exploring Naturalism in Stephen Crane’s The Open Boat, which will guide the readers to understand American Naturalism accurately and thoroughly. It firstly in-troduces the author and his novel The Open Boat. Secondly, it progressively dissects Naturalism. It not only analyses the general characteristics of Naturalism with details in The Open Boat, but also interprets the distinguishing features of American Naturalism so that readers can better understand the features of American Naturalism. Through textual perusal, it further studies the unique characteristics of Stephen Crane’s Naturalism and lays particular emphasis on Crane’s special concern on the awakening of hu-manity. It is hoped that this thesis can help readers get an in-depth comprehension of Naturalism and gain some inspiration from The Open Boat.

  14. On State Estimation with Bad Data Detection

    CERN Document Server

    Xu, Weiyu; Tang, Ao

    2011-01-01

    In this paper, we consider the problem of state estimation through observations possibly corrupted with both bad data and additive observation noises. A mixed $\\ell_1$ and $\\ell_2$ convex programming is used to separate both sparse bad data and additive noises from the observations. Through using the almost Euclidean property for a linear subspace, we derive a new performance bound for the state estimation error under sparse bad data and additive observation noises. Our main contribution is to provide sharp bounds on the almost Euclidean property of a linear subspace, using the "escape-through-a-mesh" theorem from geometric functional analysis. We also propose and numerically evaluate an iterative convex programming approach to performing bad data detections in nonlinear electrical power networks problems.

    The author was the founder and secretary pro-tem of the Bad Poets Society at Princeton Theological Seminary. This distinction does not appear on his official resume. The Society did not have meetings but it had a newsletter that came out several times a year comprised of bad poetry written by members of the faculty and staff. These poetic works included reflections on institutional matters. This article contains bad poetry by the author relating to such matters. This poetry illustrates Sigmund Freud's (Jokes and Their Relation to the Unconscious. Norton, New York, 1960) view of humor as saving in the expenditure of painful emotions, costly inhibitions, and difficult thinking. The parasitical nature of bad poetry is also noted and illustrated with the author's own poems.

    Objective: In a regional hospital, many patients are newly diagnosed with cancer. Breaking the bad news in these patients and their relatives is a tough task. Many doctors are not experienced in talking to patients about death or death-related diseases. In recent years, there have been great efforts to change the current situation. The aim of this study was to investigate the experience and education of medical personnel in breaking bad news in a secondary hospital. Materials and Methods: 59 doctors from General Hospital of Komotini, Greece were included in the study. All the doctors were in clinical specialties that treated cancer patients. A brief questionnaire was developed based on current guidelines such as Baile/SPIKES framework and the ABCDE mnemonic. Results: Residents are involved in delivering bad news less frequently than specialists. Only 21 doctors (35.59%) had specific training on breaking bad news. 20 doctors (33.90%) were aware of the available techniques and protocols on breaking bad news. 47 doctors (79.66%) had a consistent plan for breaking bad news. 57 (96.61%) delivered bad news in a quiet place, 53 (89.83%) ensured no interruptions and enough time, 53 (89.83%) used simple words and 54 (91.53%) checked for understanding and did not rush through the news. 46 doctors (77.97%) allowed relatives to determine patient's knowledge about the disease. Conclusions: There were low rates of specific training in breaking bad news. However, the selected location, the physician's speech and their plan were according to current guidelines. PMID:25709183

    2016-10-01

    The self-propulsion of a heavy, superoleophobic, metallic micro-boat carrying a droplet of various aqueous alcohol solutions as a fuel tank is reported. The micro-boat is driven by the solutocapillary Marangoni flow. The jump in the surface tension owing to the condensation of alcohols on the water surface was established experimentally. Maximal velocities of the self-propulsion were registered as high as 0.05m/s. The maximal velocity of the center mass of the boat correlates with the maximal change in the surface tension, due to the condensation of alcohols. The mechanism of the self-locomotion is discussed. The phenomenological dynamic model describing the self-propulsion is reported.

    Wake energy recovery of a ship's propeller is an important research subject in ship propulsion field. Based on the study on the mechanism analysis and computation method of the hydrodynamic performance of the propeller-rudder-rudder bubble combination, computer simulation system was built and then used to design and simulate four kinds of rudder bubbles, then the model comparison tests with the original rudder was carried out and the sensible factors influencing the energy-saving effects of rudder bubble was also analyzed. On this basis, a further optimized design of the rudder bubble for a fishing boat was put forward, and comparison test on a real boat was then carried out. It is shown that the optimized rudder bubble design can effectively recover wake energy of ships and the rudder bubble installation features a simple operation and high cost-effectiveness, and the energy-saving effect of real boat test achieves 5.1%.

    2016-02-01

    This article gives a measure of life jacket (LJ) effectiveness in U.S. recreational boating. Using the U.S. Coast Guard's Boating Accident Report Database from 2008 to 2011, we find that LJ wear is one of the most important determinants influencing the number of recreational boating fatalities, together with the number of vessels involved, and the type and engine of the vessel(s). We estimate a decrease in the number of deceased per vessel of about 80% when the operator wears their LJs compared to when they do not. The odds of dying are 86% higher than average if the accident involves a canoe or kayak, but 80% lower than average when more than one vessel is involved in the accident and 34% lower than average when the operator involved in the accident has more than 100 hours of boating experience. Interestingly, we find that LJ effectiveness decreases significantly as the length of the boat increases and decreases slightly as water temperature increases. However, it increases slightly as the operator's age increases. We find that between 2008 and 2011, an LJ regulation that requires all operators to wear their LJs-representing a 20% increase in wear rate-would have saved 1,721 (out of 3,047) boaters or 1,234 out of 2,185 drowning victims. The same policy restricted to boats 16-30 feet in length would have saved approximately 778 victims. Finally, we find that such a policy would reduce the percentage of drowning victims compared to other causes of death. © 2015 Society for Risk Analysis.

Do similar storms from smaller stars M dwarfs like V374 Peg, or the nearby Proxima Centauri mean bad news for the planets that these stars host?Volatile StarsDifference in habitable-zone sizes for different stellar types. [NASA]When plasma is released from the Sun in the form of a CME traveling toward Earth, these storms can be powerful enough to disrupt communications and navigational equipment, damage satellites, and cause blackouts even with our planetary magnetic field to protect us! How might planets in the habitable zone of M-dwarf stars fare against similar storms?The first danger for an M dwarfs planets is that the habitable zone lies much closer to the star: it can range from 0.03 to 0.4 AU (i.e., within Mercurys orbit). Being so close to the star definitely makes a planet in an M dwarfs habitable zone vulnerable to storms.Colors indicate the probability of CME impact, for different different stellar latitudes where the CME originated vs. orbital inclination of the planet, (a) without any deflection, and (b) taking into account the CME deflection by the stars magnetic field. Hanging out in an orbit aligned with the current sheet turns out to be a bad idea. [Adapted from Kay et al. 2016]What about the storms themselves? You might think that because M dwarfs are cooler stars, they would be quieter, releasing fewer CMEs with less energy. Surprisingly, the opposite is true: M dwarfs are significantly more active than solar-type stars, and the CMEs are typically ten times more massive than those released from the Sun. Impacts from these powerful outbursts could easily strip any existing planet atmosphere, making a planet much less likely to be habitable. To make matters worse, M dwarfs can remain magnetically active for billions of years: even a star like Proxima Centauri, which is nearly 5 billion years old, isstill relatively

  9. Computer codes for evaluation of control room habitability (HABIT)

    Energy Technology Data Exchange (ETDEWEB)

    Stage, S.A. [Pacific Northwest Lab., Richland, WA (United States)

    1996-06-01

    This report describes the Computer Codes for Evaluation of Control Room Habitability (HABIT). HABIT is a package of computer codes designed to be used for the evaluation of control room habitability in the event of an accidental release of toxic chemicals or radioactive materials. Given information about the design of a nuclear power plant, a scenario for the release of toxic chemicals or radionuclides, and information about the air flows and protection systems of the control room, HABIT can be used to estimate the chemical exposure or radiological dose to control room personnel. HABIT is an integrated package of several programs that previously needed to be run separately and required considerable user intervention. This report discusses the theoretical basis and physical assumptions made by each of the modules in HABIT and gives detailed information about the data entry windows. Sample runs are given for each of the modules. A brief section of programming notes is included. A set of computer disks will accompany this report if the report is ordered from the Energy Science and Technology Software Center. The disks contain the files needed to run HABIT on a personal computer running DOS. Source codes for the various HABIT routines are on the disks. Also included are input and output files for three demonstration runs.

  10. SMEs’ Purchasing Habits

    Directory of Open Access Journals (Sweden)

    Emre S. Ozmen

    2014-05-01

    Full Text Available Although micro companies overpower the small and medium enterprise (SME segment, generalizations are often with medium size companies, and therefore, there are many unknowns, especially when it comes to its buying behavior. Conformist studies and industry practices assume SMEs to be “normative” or “conservative” buyers; however, this hypothesis is untested. This article aims to scrutinize the reality, and proposes a unified model that rejects pre-containerization in buying behavior typologies, as well as selectiveness in terms of audience type, whether it is corporate, SME, or consumer. While replacing researchers’ perceptions with the audience’s, the model yields actual knowledge that can lead to audience’s beliefs in lieu of the opposite, which is used to mislead stakeholders. The study shows that SMEs also buy like individuals and spend in a similar way to consumers’, including not only “normative” and “conservative” but also “negligent” and “impulse” zones. From the research-implications perspective, future studies by behaviorists can explore why SMEs purchase in this way. Marketers may benefit from the finding that SMEs buy like individuals. In addition, SMEs may want to be conscious of their purchasing habits, and—utilizing the newly introduced “risk score” frontier—policymakers should assess the consequences of these habits at the macro level.

  11. Circumbinary Habitability Niches

    Binaries could provide the best niches for life in the galaxy. Though counterintuitive, this assertion follows directly from stellar tidal interaction theory and the evolution of lower mass stars. There is strong evidence that chromospheric activity of rapidly rotating young stars may be high enough to cause mass loss from atmospheres of potentially habitable planets. The removal of atmospheric water is most critical. Tidal breaking in binaries could help reduce magnetic dynamo action and thereby chromospheric activity in favor of life. We call this the Binary Habitability Mechanism (BHM), that we suggest allows for water retention at levels comparable to or better than Earth. We discuss novel advantages that life may exploit, in these cases, and suggest that life may even thrive on some circumbinary planets. We find that while many binaries do not benefit from BHM, high quality niches do exist for various combinations of stars between 0.55 and 1.0 solar masses. For a given pair of stellar masses, BHM operate...

    Ditto, Thomas D.

    2012-09-01

    A notional space telescope configuration is presented that addresses issues of angular resolution, spectral bandwidth and rejection of host star glare by means of a double dispersion architecture. The telescope resolves angle by wavelength. In an earlier embodiment for surveys, a primary objective grating telescope architecture was shown to acquire millions of objects in one observation cycle, one wave length at a time. The proposed HPF can detect exquisite spectral signatures out of millions of wavelengths in albedos - one exoplanetary system at a time. Like its predecessor, the new HPF telescope has a ribbon-shaped flat gossamer membrane primary objective that lends itself to space deployment, but the preferred embodiment uses a holographic optical element rather than a plane grating. The HOE provides an improvement in efficiency at select wavelength bands. The considerable length of the membrane can be in the 100 meter class providing angular resolution sufficient to resolve planets in the habitable zone and also spectral resolution sufficient to earmark habitability. A novel interferometric secondary spectrograph rejects host star glare. However, the architecture cannot disambiguate multiple stellar sources and may require unprecedented focal lengths in the primary objective to isolate one system at a time.

  1. Bad apples, bad cases, and bad barrels: meta-analytic evidence about sources of unethical decisions at work.

    Science.gov (United States)

    Kish-Gephart, Jennifer J; Harrison, David A; Treviño, Linda Klebe

    2010-01-01

    As corporate scandals proliferate, practitioners and researchers alike need a cumulative, quantitative understanding of the antecedents associated with unethical decisions in organizations. In this meta-analysis, the authors draw from over 30 years of research and multiple literatures to examine individual ("bad apple"), moral issue ("bad case"), and organizational environment ("bad barrel") antecedents of unethical choice. Findings provide empirical support for several foundational theories and paint a clearer picture of relationships characterized by mixed results. Structural equation modeling revealed the complexity (multidetermined nature) of unethical choice, as well as a need for research that simultaneously examines different sets of antecedents. Moderator analyses unexpectedly uncovered better prediction of unethical behavior than of intention for several variables. This suggests a need to more strongly consider a new "ethical impulse" perspective in addition to the traditional "ethical calculus" perspective. Results serve as a data-based foundation and guide for future theoretical and empirical development in the domain of behavioral ethics.

  14. Adaptive bad pixel correction algorithm for IRFPA based on PCNN

    Leng, Hanbing; Zhou, Zuofeng; Cao, Jianzhong; Yi, Bo; Yan, Aqi; Zhang, Jian

    2013-10-01

    Bad pixels and response non-uniformity are the primary obstacles when IRFPA is used in different thermal imaging systems. The bad pixels of IRFPA include fixed bad pixels and random bad pixels. The former is caused by material or manufacture defect and their positions are always fixed, the latter is caused by temperature drift and their positions are always changing. Traditional radiometric calibration-based bad pixel detection and compensation algorithm is only valid to the fixed bad pixels. Scene-based bad pixel correction algorithm is the effective way to eliminate these two kinds of bad pixels. Currently, the most used scene-based bad pixel correction algorithm is based on adaptive median filter (AMF). In this algorithm, bad pixels are regarded as image noise and then be replaced by filtered value. However, missed correction and false correction often happens when AMF is used to handle complex infrared scenes. To solve this problem, a new adaptive bad pixel correction algorithm based on pulse coupled neural networks (PCNN) is proposed. Potential bad pixels are detected by PCNN in the first step, then image sequences are used periodically to confirm the real bad pixels and exclude the false one, finally bad pixels are replaced by the filtered result. With the real infrared images obtained from a camera, the experiment results show the effectiveness of the proposed algorithm.

  15. Rainmakers: why bad weather means good productivity.

    Science.gov (United States)

    Lee, Jooa Julia; Gino, Francesca; Staats, Bradley R

    2014-05-01

    People believe that weather conditions influence their everyday work life, but to date, little is known about how weather affects individual productivity. Contrary to conventional wisdom, we predict and find that bad weather increases individual productivity and that it does so by eliminating potential cognitive distractions resulting from good weather. When the weather is bad, individuals appear to focus more on their work than on alternate outdoor activities. We investigate the proposed relationship between worse weather and higher productivity through 4 studies: (a) field data on employees' productivity from a bank in Japan, (b) 2 studies from an online labor market in the United States, and (c) a laboratory experiment. Our findings suggest that worker productivity is higher on bad-, rather than good-, weather days and that cognitive distractions associated with good weather may explain the relationship. We discuss the theoretical and practical implications of our research.

  2. The evolution of galaxy habitability

    CERN Document Server

    Gobat, R

    2016-01-01

    We combine a semi-analytic model of galaxy evolution with constraints on circumstellar habitable zones and the distribution of terrestrial planets to probe the suitability of galaxies of different mass and type to host habitable planets, as well as its evolution with time. We find that the fraction of stars with terrestrial planets in their habitable zone ("habitability") depends only weakly on galaxy mass, with a maximum around 4e10 Msun. We estimate that 0.7% of all stars in Milky Way type galaxies to host a terrestrial planet within their habitable zone, consistent with the value derived from Kepler observations. On the other hand, the habitability of passive galaxies is slightly but systematically higher, unless we assume an unrealistically high sensitivity of planets to supernovae. We find that the overall habitability of galaxies has not changed significantly in the last ~8 Gyr, with most of the habitable planets in local disk galaxies having formed ~1.5 Gyr before our own solar system. Finally, we expe...

    2014-01-01

    With the discovery of hundreds of exoplanets and a potentially huge number of Earth-like planets waiting to be discovered, the conditions for their habitability have become a focal point in exoplanetary research. The classical picture of habitable zones primarily relies on the stellar flux allowing liquid water to exist on the surface of an Earth-like planet with a suitable atmosphere. However, numerous further stellar and planetary properties constrain habitability. Apart from "geophysical" processes depending on the internal structure and composition of a planet, a complex array of astrophysical factors additionally determine habitability. Among these, variable stellar UV, EUV, and X-ray radiation, stellar and interplanetary magnetic fields, ionized winds, and energetic particles control the constitution of upper planetary atmospheres and their physical and chemical evolution. Short- and long-term stellar variability necessitates full time-dependent studies to understand planetary habitability at any point ...

    Opalinski, Andra S; Weglicki, Linda S; Gropper, Sareen S

    2017-05-25

    The aim of this article is to provide clarity of the concept of health habit. Using Walker and Avant's (1983; 2010) method for conducting a concept analysis, the authors identify the attributes and characteristics of health habit, its theoretical and practical application to nursing, and sample cases to further illustrate the concept. Empirical and conceptual literature was used to inform this concept analysis.

  5. Portfolio Optimization under Habit Formation

    CERN Document Server

    Naryshkin, Roman

    2008-01-01

    The "standard" Merton formulation of optimal investment and consumption involves optimizing the integrated lifetime utility of consumption, suitably discounted, together with the discounted future bequest. In this formulation the utility of consumption at any given time depends only on the amount consumed at that time. However, it is both theoretically and empirically reasonable that an individuals utility of consumption would depend on past consumption history. Economists term this "Habit Formation". We introduce a new formulation of habit formation which allows non-addictive consumption patterns for a wide variety of utility specification. In this paper we construct a simple mathematical description of this habit formation and present numerical solutions. We compare the results with the standard ones and draw insights obtained from the habit formation. The consumption path tends to increase with time and be less sensitive to the market fluctuations, which perfectly reflects the existence of habit persistenc...

  6. Comparative Habitability of Transiting Exoplanets

    CERN Document Server

    Barnes, Rory; Evans, Nicole

    2015-01-01

    Exoplanet habitability is traditionally assessed by comparing a planet's semi-major axis to the location of its host star's "habitable zone," the shell around a star for which Earth-like planets can possess liquid surface water. The Kepler space telescope has discovered numerous planet candidates near the habitable zone, and many more are expected from missions such as K2, TESS and PLATO. These candidates often require significant follow-up observations for validation, so prioritizing planets for habitability from transit data has become an important aspect of the search for life in the universe. We propose a method to compare transiting planets for their potential to support life based on transit data, stellar properties and previously reported limits on planetary emitted flux. For a planet in radiative equilibrium, the emitted flux increases with eccentricity, but decreases with albedo. As these parameters are often unconstrained, there is an "eccentricity-albedo degeneracy" for the habitability of transiti...

    2003-01-01

    Shortly before his death in 1995, Kenneth B. Schwartz, a cancer patient at Massachusetts General Hospital (MGH), founded The Kenneth B. Schwartz Center at MGH. The Schwartz Center is a nonprofit organization dedicated to supporting and advancing compassionate health care delivery that provides hope to the patient, support to caregivers, and encourages the healing process. The Center sponsors the Schwartz Center Rounds, a monthly multidisciplinary forum where caregivers reflect on important psychosocial issues faced by patients, their families, and their caregivers, and gain insight and support from fellow staff members. Clinicians in the field of oncology are unavoidably forced to break bad news. The Schwartz Center Rounds focuses on issues of communication between patients and their caregivers, one of the most difficult aspects of which is breaking bad news. The invited patient, a woman who had been living with a low-grade cancer for many years, spoke about her experiences both as a person living with cancer and as the daughter of a patient diagnosed with cancer. Her father's suicide, precipitated by being told his diagnosis, puts the horror of receiving bad news into stark relief. She provides a fascinating account of how she proactively adjusted to her diagnosis, and fought for optimal quality of life. This article discusses issues of support, abandonment, and how hope is conveyed, and reviews the literature that informs good clinical practice in breaking bad news.

  10. THE HABIT OF CURIOSITY

    Full Text Available Curiosity is commonly referred to as a way of being, or an object of curiosity. How curiosity is part of our daily lives, how we engage with curiosity intellectually has a long and interesting history. Since the sixteenth century it has been manifest in cabinets of curiosity, museums and curio cabinets; exercises in collecting, self-reflection and discovery. However, the end of the twentieth-century has altered our sense of the world, through the speed and accessibility of information leaving a changed relationship with wonder. This paper discusses the role of curiosity in research as a “habit of curiosity”, (Benedict 2001, 2 a method for discovery. It reviews its historical manifestations and concerns, locating it through objects and actions, and questions what new meanings the twenty-first century brings with it. Is curiosity at risk? Is it still risky? The relationship between the individual and their interior and exterior socio-cultural landscape continually creates new meanings for knowledge and how we achieve it. This shadowy landscape of our curiosity has not lost meaning intellectually, but it in our shrinking, globalized world how we engage with it requires a new investigation.

  11. [Oral habits. Etiology and treatment].

    Romanou-Kouvelas, K; Kouvelas, N

    1988-01-01

    Oral habits have been described by psychologists and psychyatrists as psychodynamic phenomena. Dentists are concerned with oral habits because of the detrimental consequences they have in the oral facial system. The dentist who is in a position to confront a child with an oral habit in order to treat his dentinofacial problems is required to be aware of the psychological background of his patient as well as of the conditions under which the children do the habit in order to overcome emotional difficulties. The dentist should also search into the child's family to find out what the causes of the child's oral habit maybe. For the treatment of an oral habit the dentist should ensure both the child's and the family's cooperation and he should be aware of the advantages and disadvantages of every available method for treatment. Methods of treatment are: Use of orthodontic appliances: This method has the disadvantage that disturbs the child's psychological need for the habit, it can be interpreted as a punishment, it is visible and it causes speaking difficulties. It should be applied only in cooperation with the child. Behavioristic technique: This method aims to reinforce the child's positive behavior according to the Skinnerian principle: stimulus-response-reward. It has fast results but it is a conditioned treatment. Psychoanalytic method: It could solve the problem of the child's primary need for the oral habit in a radical manner. However it is practically impossible to be applied in Dentistry. Behavior modification according to ego psychology. With this method we attempt to analyse and understand the psychological cause of an oral habit.(ABSTRACT TRUNCATED AT 250 WORDS)

    Lignitz, Eberhard; Lustig, Martina; Scheibe, Ernst

    2014-01-01

    Deaths on the water are common in the autopsy material of medicolegal institutes situated on the coast or big rivers and lakes (illustrated by the example of the Institute of Legal Medicine of Greifswald University). They mostly occur during recreational boating activities. Apart from hydro-meteorological influences, human error is the main cause of accidents. Often it is not sufficiently kept in mind whether the boat crew is fit for sailing and proper seamanship is ensured. Drowning (following initial hypothermia) is the most frequent cause of death. Medicolegal aspects are not decisive for ordering a forensic autopsy. As statistics are not compiled in a uniform way, a comparison of the data of different institutions engaged in investigating deaths at sea and during water sports activities is hardly possible, neither on a national nor an international basis--and the reconstruction of aquatic accidents is generally difficult. Fatal accidents can only be prevented by completely clarifying their causes.

  16. Impact of boat-generated waves on intertidal estuarine sediments

    2010-12-01

    Hydrodynamics in the macrotidal Seine estuary (France) are controlled by the semi-diurnal tidal regime modulated seasonally by the fluvial discharge. Wind effect on sediment transport (through wind waves and swell) is observed at the mouth of the estuary. Over the last century, authorities have put emphasis on facilitating economic exchanges by means of embankment building and increased dredging activity. These developments led to allow and secure sea vessel traffic in the Seine estuary (from its mouth to the port of Rouen, 125 km upstream) but they also resulted in a change of estuarine hydrodynamics and sediment transport features. A riversides restoration policy has been recently started by port authorities. In this context, the objective of the field-based study presented is to connect vessel characteristics (i.e. speed, draft...), boat-generated waves and their sedimentary impacts. Such information will be used by stakeholders to manage riverside. The natural intertidal site of interest is located in the fluvial freshwater part of the Seine estuary characterized by a 4.5 m maximum tidal range. The foreshore slope is gently decreasing and surface sediments are composed of fine to coarse sand with occasional mud drapes. In order to decipher boat-generated events, the sampling strategy is based on continuous ADV measurements coupled with a turbidimeter and an altimeter to study sediment dynamics. These instruments are settled in the lower part of the foreshore (i) to obtain a significant dataset (i.e. oceanic instruments are not measuring in air) on a zone statically affected by boat waves and (ii) because most of boat traffic occurs during early flood or late ebb period. Spatial variations are assessed along a cross-section through grain-size analysis of surface sediments and topography measurements using pole technique. Results enhance hydrodynamic and sedimentary impacts of boat-generated waves compared respectively to tidal and wind effects. Long

    2009-01-01

    We review how tides may impact the habitability of terrestrial-like planets. If such planets form around low-mass stars, then planets in the circumstellar habitable zone will be close enough to their host stars to experience strong tidal forces. We discuss 1) decay of semi-major axis, 2) circularization of eccentric orbits, 3) evolution toward zero obliquity, 4) fixed rotation rates (not necessarily synchronous), and 5) internal heating. We briefly describe these effects using the example of a 0.25 solar mass star with a 10 Earth-mass companion. We suggest that the concept of a habitable zone should be modified to include the effects of tides.

    The fossil record shows that the Earth has experienced several mass extinctions over the past 500 million years1, and it has been suggested that there is a periodicity in extinction events on timescales of tens1 and/or hundreds of millions of years. Various hypotheses have been proposed to explain the cause of the mass extinctions, including the suggestion that the Earth's ozone layer may have been destroyed by intense radiation from a nearby supernovae2- 3, exposing the Earth's surface to damaging UV radiation. Recent observations of cores taken from the ocean floor revealed atoms of a very rare isotope of iron (60Fe) believed to have arrived on Earth around 2 million years ago as fallout from a nearby supernovae4. Astronomical evidence for that past supernovae was recently found in the debris of a young cluster of massive stars5, by tracing its past orbit, putting it at the right place at the right time to explain the mild extinction event. Here we report new high-resolution (both in space and time) N-body chemodynamical simulations (carried out with our novel code GCD+6) of the evolution of a model Milky Way Galaxy, tracing the orbit of èsun-like' stars over a 500 million year period, checking the proximity to supernovae throughout the history of the orbit and comparing the times when this occurs with past mass extinctions on Earth. We additionally explain the important effects of the spiral arm pattern, radial migration of stars and Galactic chemistry on habitability.

    We discuss the possibility of screening the atmosphere of exomoons for habitability. We concentrate on Earth-like satellites of extrasolar giant planets (EGP) which orbit in the Habitable Zone of their host stars. The detectability of exomoons for EGP in the Habitable Zone has recently been shown to be feasible with the Kepler Mission or equivalent photometry using transit duration observations. Using the Earth itself as a proxy we show the potential and limits of spectroscopy to detect biomarkers on an Earth-like exomoon and discuss effects of tidal locking for such potential habitats. Transmission spectroscopy of exomoons is a unique potential tool to screen them for habitability in the near future.

    Using coordination polyhedron rule, growth habit of polar crystals such as ZnO, ZnS and SiO2 is investigated. It shows that the growth rates in the positive and negative polar axis directions are different. The theoretical growth habit of ZnO crystal is hexagonal prism and the growth rates of its various faces are:V{0001}>V{0111}-->V{0110}->V{0111}->V{0001}-. The growth habit of ZnS crystal is tetrahedron and its growth rates of different crystal faces are: V{111}>V{001}>V{001} =V{100} =. The growth rate relationship between positive and negative polar axis directions of SiO2 crystal V[1120]-->V[1120]-.is These results are in agreement with the growth habits observed under hydrothermal conditions. The different growth rates between positive and negative polar axis directions cannot be explained by PBC theory.

    The habitable zone (HZ) is defined as the region around a star where a planet can support liquid water on its surface, which, together with an oxygen atmosphere, is presumed to be necessary (and sufficient) to develop and sustain life on the planet. Currently, about twenty potentially habitable planets are listed. The most intriguing question driving all these studies is whether planets within habitable zones host extraterrestrial life. It is implicitly assumed that a planet in the habitable zone bears biota. However along with the two usual indicators of habitability, an oxygen atmosphere and liquid water on the surface, an additional one -- the age --- has to be taken into account when the question of the existence of life (or even a simple biota) on a planet is addressed. The importance of planetary age for the existence of life as we know it follows from the fact that the primary process, the photosynthesis, is endothermic with an activation energy higher than temperatures in habitable zones. Therefore on...

    For any real pair i, j geq 0 with i+j=1 let Bad(i, j) denote the set of (i, j)-badly approximable pairs. That is, Bad(i, j) consists of irrational vectors x:=(x_1, x_2) in R^2 for which there exists a positive constant c(x) such that max {||qx_1||^(-i), ||qx_2||^(-j)} > c(x)/q for all q in N. Building on a result of Kurzweil, a new characterization of the set Bad(i, j) in terms of `well-approximable' vectors in the area of `twisted' inhomogeneous Diophantine approximation is established. In addition, it is shown that Bad^x(i, j), the `twisted' inhomogeneous analogue of Bad(i, j), has full Hausdorff dimension 2 when x is chosen from the set Bad(i, j).

    2016-11-01

    The aim of this study was to map Togolese people's positions regarding the breaking of bad news to elderly patients. Two hundred eleven participants who had in the past received bad medical news were presented with 72 vignettes depicting communication of bad news to elderly female patients and asked to indicate the acceptability of the physician's conduct in each case. The vignettes were all combinations of five factors: (a) the severity of the disease, (b) the patient's wishes about disclosure, (c) the level of social support during hospitalization, (d) the patient's psychological robustness, and (e) the physician's decision about how to communicate the bad news. Five qualitatively different positions were found. Two percent of the participants preferred that the physician always tell the full truth to both the patient and her relatives, 8% preferred that the truth be told depending on the physician's perception of the situation, 15% preferred that the physician tell the truth but understood that in some cases nondisclosure to the patient was not inappropriate, 33% preferred that the physician tell the full truth to the relatives but not as much information to the patient, and 42% preferred that the physician tell the full truth to the relatives only. These findings present a challenge to European physicians taking care of African patients living in Europe or working in African hospitals, and to African physicians trained in Europe and now working in their home countries. If these physicians respect the imperative of always telling the truth directly to their patients, their behavior may trigger anger and considerable misunderstanding among African patients and their families.

    The remains of an ancient wooden boat were unearthed at the Bibong-ri shell mound site. The site was located at Bibong-ri, Bugog-myeon, Changnyeong-gun, Gyeongsangnam-do in South Korea. A substantial fragment of the vessel was discovered in the lowest layer of the site. We collected 17 samples of charcoal and wood from pebble, sand, and shell layers. Sample preparation extracted the carbon from each sample material and converted it into graphite for AMS radiocarbon dating. Radiocarbon dates of the samples indicate that they belong to the Neolithic period and that the boat dates from ca. 5700 BC. To this point, the oldest known boat in the world has been a wooden boat dating from ca. 5500 BC in China. Other ancient boats from around the world include a logboat dating from ca. 3600 BC in Japan and a fleet of wooden boats dating from ca. 3000 BC in Egypt. The Bibong-ri boat is the first boat from the Neolithic period ever found in South Korea and must represent one of the world's oldest known boats.

  20. The behavioural response of Australian fur seals to motor boat noise.

    Directory of Open Access Journals (Sweden)

    Joy S Tripovich

    Full Text Available Australian fur seals breed on thirteen islands located in the Bass Strait, Australia. Land access to these islands is restricted, minimising human presence but boat access is still permissible with limitations on approach distances. Thirty-two controlled noise exposure experiments were conducted on breeding Australian fur seals to determine their behavioural response to controlled in-air motor boat noise on Kanowna Island (39°10'S, 146°18'E. Our results show there were significant differences in the seals' behaviour at low (64-70 dB versus high (75-85 dB sound levels, with seals orientating themselves towards or physically moving away from the louder boat noise at three different sound levels. Furthermore, seals responded more aggressively with one another and were more alert when they heard louder boat noise. Australian fur seals demonstrated plasticity in their vocal responses to boat noise with calls being significantly different between the various sound intensities and barks tending to get faster as the boat noise got louder. These results suggest that Australian fur seals on Kanowna Island show behavioural disturbance to high level boat noise. Consequently, it is recommended that an appropriate level of received boat sound emissions at breeding fur seal colonies be below 74 dB and that these findings be taken into account when evaluating appropriate approach distances and speed limits for boats.

  2. Comparative Habitability of Transiting Exoplanets

    Exoplanet habitability is traditionally assessed by comparing a planet’s semimajor axis to the location of its host star’s “habitable zone,” the shell around a star for which Earth-like planets can possess liquid surface water. The Kepler space telescope has discovered numerous planet candidates near the habitable zone, and many more are expected from missions such as K2, TESS, and PLATO. These candidates often require significant follow-up observations for validation, so prioritizing planets for habitability from transit data has become an important aspect of the search for life in the universe. We propose a method to compare transiting planets for their potential to support life based on transit data, stellar properties and previously reported limits on planetary emitted flux. For a planet in radiative equilibrium, the emitted flux increases with eccentricity, but decreases with albedo. As these parameters are often unconstrained, there is an “eccentricity-albedo degeneracy” for the habitability of transiting exoplanets. Our method mitigates this degeneracy, includes a penalty for large-radius planets, uses terrestrial mass-radius relationships, and, when available, constraints on eccentricity to compute a number we call the “habitability index for transiting exoplanets” that represents the relative probability that an exoplanet could support liquid surface water. We calculate it for Kepler objects of interest and find that planets that receive between 60% and 90% of the Earth’s incident radiation, assuming circular orbits, are most likely to be habitable. Finally, we make predictions for the upcoming TESS and James Webb Space Telescope missions.

    Oral habits or parafunction may contribute to dental, periodontal, or neuromuscular damage. Such habits, of which the patient is often unaware, may cause considerable damage. Habits may be occlusal or non-occlusal, and may affect the dentition and/or the oral soft tissues. Drawing a patient's attention to the damage caused by some habits of which he or she is unaware often leads to cessation, whereas with certain conscious habits, such as nail or finger biting, success is much more limited.

    The objectives of this study were to profile the physiological and physical characteristics of elite dragon boat paddlers, to identify characteristics that predict race performance and to quantify the metabolic energy contributions to simulated 200-m and 500-m dragon boat racing. Eleven, national level, male, Japanese dragon boat paddlers completed a battery of tests on a paddling ergometer including an incremental maximal aerobic capacity test, a 2-minute maximal accumulated oxygen deficit (MAOD) test, and simulated 200-m and 500-m races. A physiological and physical profile of subjects was compiled. Results showed that 200-m race performance correlated with flexed arm girth and excess postexercise oxygen consumption (EPOC) measured in the 30 minutes after the MAOD test, whereas 500-m race performance correlated with body fat percentage, relaxed and flexed arm girth, MAOD, EPOC, and peak power during the MAOD test. Stepwise multiple regression revealed that flexed arm girth was the most powerful predictor of 200-m and 500-m race performance, followed by EPOC with the combination of these 2 factors able to explain 74% and 68% of the variance in 200-m and 500-m race performance, respectively. Aerobic energy contributions for 200-m (50 seconds) and 500-m (1 minute 50 seconds) races were (mean (95% confidence intervals)) 52.1% (range, 47.4-56.8%) and 67.5% (range, 60.1-77.8%), respectively. In conclusion, coaches should develop training programs targeted at developing upper-body musculature and increasing anaerobic capacity because these factors are the strongest predictors of 200-m and 500-m race performance. Given the substantial aerobic energy contributions even for a 200-m race event, coaches should aim to increase the maximal aerobic capacity of the paddler in preparation for both 200-m and 500-m events.

      The Open Boat is one of the best realistic stories written by Stephen Crane, an early American naturalist and impressionist writer who dramatically presents the subtle relation between man and nature as well as that of man and society. His personal experience on the sea has an enormous impact on the story. This paper tries to carry out a detailed examination of the story in the light of writing style in order to explore his unique style and the beauty of the story.

  8. Compression fractures of the vertebrae during a "bumpy" boat ride.

    2012-01-31

    INTRODUCTION: Compression fracture of the vertebrae is common, often the result of falls from height and motor vehicle accidents in the younger age groups. It can occur following minor trauma in the elderly and in those with osteoporosis. MATERIALS AND METHODS: We present an interesting case of compression fracture of the vertebral bodies occurring simultaneously in a couple during a boat ride while on holiday. One individual had fracture of the T8, while the other fractured the L1 vertebrae. Both injuries were treated conservatively with Taylor braces. CONCLUSION: We highlight one of the potential hazards of this recreational activity, and the almost identical fracture pattern in this couple.

  9. Antisocial features and "faking bad": A critical note.

    2015-01-01

    We critically review the literature on antisocial personality features and symptom fabrication (i.e., faking bad; e.g., malingering). A widespread assumption is that these constructs are intimately related. Some studies have, indeed, found that antisocial individuals score higher on instruments detecting faking bad, but others have been unable to replicate this pattern. In addition, studies exploring whether antisocial individuals are especially talented in faking bad have generally come up with null results. The notion of an intrinsic link between antisocial features and faking bad is difficult to test and research in this domain is sensitive to selection bias. We argue that research on faking bad would profit from further theoretical articulation. One topic that deserves scrutiny is how antisocial features affect the cognitive dissonance typically induced by faking bad. We illustrate our points with preliminary data and discuss their implications.

    Video games are a pervasive pastime among children and adolescents. The growing popularity of video games has instigated a debate among parents, researchers, video game producers, and policymakers concerning potential harmful and helpful effects of video games on children. This article provides an overview of research findings on the positive and negative effects of video games, thus providing an empirical answer to the question, are video games good or bad? The article also provides some guidelines to help pediatricians, parents, and other caregivers protect children from negative effects and to maximize positive effects of video games.

    Full Text Available The role of competition in healthcare is much debated. Despite a wealth of international experience in relation to competition, evidence is mixed and contested and the debate about the potential role for competition is often polarised. This paper considers briefly some of the reasons for this, focusing on what is meant by “competition in healthcare” and why it is more valuable to think about the circumstances in which competition is more and less likely to be a good tool to achieve benefits, rather than whether or not it is “good” or “bad,” per se.

  14. Has aid for AIDS raised all health funding boats?

    Shiffman, Jeremy; Berlan, David; Hafner, Tamara

    2009-11-01

    Global health analysts have debated whether donor prioritization of HIV/AIDS control has lifted all boats, raising attention and funding levels for health issues aside from HIV/AIDS. We investigate this question, considering donor funding for 4 historically prominent health agendas-HIV/AIDS, health systems strengthening, population and reproductive health, and infectious disease control-over the decade 1998-2007. We employ funding data from the Development Assistance Committee of the Organization for Economic Cooperation and Development, which tracks donor aid. The data indicate that HIV/AIDS may have helped to increase funding for the control of other infectious diseases; however, there is no firm evidence that other health issues beyond the control of infectious diseases have benefited. Between 1998 and 2007, funding for HIV/AIDS control rose from just 5.5% to nearly half of all aid for health. Over the same period, funding for health systems strengthening declined from 62.3% to 23.9% of total health aid and that for population and reproductive health declined from 26.4% to 12.3%. Also, even as total aid for health tripled during this decade, aid for health systems strengthening largely stagnated. Overall, the data indicate little support for the contention that donor funding for HIV/AIDS has lifted all boats.

  15. Comparison of Ferry Boat and Highway Bridge Energy Use

    Directory of Open Access Journals (Sweden)

    Wayne D. Cottrell

    2011-01-01

    Full Text Available Passenger ferries serve a variety of transport needs in the U.S., such as providing vital links across bodies of water, and supplementing highway bridges. In some cases in which there is a ferry connection but no bridge, a bridge would be impractical; in other cases, a bridge might be feasible. The paper compares the energy consumption of ferries and motor vehicles on bridges, to determine which link is more fuel efficient. One finding is that limited data are available on ferry boat fuel consumption: despite there being 208 ferry boat operators in the U.S. as of 2008, only eight were providing energy use data to the National Transit Database. Examinations of three of the systems found that the passenger-MPG of the ferries ranged from 2.61 to 14.00 (1.11 to 5.95 km/L, while that of the motor vehicles on adjacent highway bridge connections ranged from 25.34 to 32.45 (10.77 to 13.79 km/L. Data from the eight systems are used to develop a ferry MPG model. The model is used to show that the Ryer Island and Charles Hall Ferries are less fuel efficient than hypothetical bridges in those locations. The fuel efficiencies and consumptions of the ferries would equal those of motor vehicles on the bridges, however, if smaller vessels were used, and if the frequency of service was reduced.

  10. Quagga and zebra mussel risk via veliger transfer by overland hauled boats

    Directory of Open Access Journals (Sweden)

    Larry B. Dalton

    2013-04-01

    Full Text Available Invasive quagga and zebra mussels (Dreissena rostriformis bugensis and Dreissena polymorpha, respectively pose a great threat to USwaters. Recreational boats constitute a significant risk for spreading the organisms. Recreational boats circulate large amounts of raw waterwhen in use, and if not drained and dried correctly can transport many mussel larvae, called veligers. Veligers experience very high mortality rates; however, the number of potentially transported veligers can be a serious risk to non-infested bodies of water, especially if multiple boats are involved. The risk of veliger transport was calculated for Lake Mead and Lake Michigan using boat capacities for water circulation and specific veliger density data. Results illustrate the importance of draining, drying, and/or decontaminating recreational boats after use.

  11. Design and realization a skiff racing boat hull made of natural fibers reinforced composite

    Collotta, M.; Solazzi, L.; Pandini, S.; Tomasoni, G.; Alberti, M.; Donzella, G.

    2016-05-01

    This paper discusses the development of a racing boat with an hull made of a composite material reinforced by natural fibers. In particular, we report here the design and realization of the boat hull, the assessment of its mechanical performance by means of a computer assisted simulation, and the cost analysis to assess the economic sustainability of the new composite developed. The results have shown that the new composite has a performance comparable with conventional glass fiber reinforced composites employed for the realization of this type of boat, accordingly to the technology employed and the lamination sequence adopted. Moreover, the FEM analysis performed over the skiff of the designed and constructed boat has demonstrated a successful choice of the material for real application, as it was later confirmed by the good performance of the boat in water. Finally, the cost analysis highlighted the economic sustainability of the new composite, allowing a cost saving of over 28% with respect to carbon fiber composites.

  12. On good and bad forms of medicalization.

    Science.gov (United States)

    Parens, Erik

    2013-01-01

    The ongoing 'enhancement' debate pits critics of new self-shaping technologies against enthusiasts. One important thread of that debate concerns medicalization, the process whereby 'non-medical' problems become framed as 'medical' problems. In this paper I consider the charge of medicalization, which critics often level at new forms of technological self-shaping, and explain how that charge can illuminate--and obfuscate. Then, more briefly, I examine the charge of pharmacological Calvinism, which enthusiasts, in their support of technological self-shaping, often level at critics. And I suggest how that charge, too, can illuminate and obfuscate. Exploring the broad charge of medicalization and the narrower counter charge of pharmacological Calvinism leads me to conclude that, as satisfying as it can be to level one of those charges at our intellectual opponents, and as tempting as it is to lie down and rest with our favorite insight, we need to gather the energy to have a conversation about the difference between good and bad forms of medicalization. Specifically, I suggest that if we consider the 'medicalization of love,' we can see why critics of and enthusiasts about technological self-shaping should want (and in some cases have already begun) to distinguish between good and bad forms of such medicalization.

    Long term habitability on the surface of planets has as a prerequisite a minimum availability of elements to build rocky planets, their atmospheres, and for life sustaining water. They must be within the habitable zone and avoid circumstances that cause them to lose their atmospheres and water. However, many astrophysical sources are hazardous to life on the surfaces of planets. Planets in harsh environments may require strong magnetic fields to protect their biospheres from high energy particles from the host star(s). Planets in harsh environments may additionally require a strong astrosphere to be sufficiently able to deflect galactic cosmic-rays. Supernovae (SNe) play a central role in the habitability of planets in the disks of star forming galaxies. Currently, the SNe rate maintains a relativistic galactic wind shielding planets in the disk from extragalactic cosmic rays. However, if the density of SNe in the disk of the galaxy were significantly higher, as it was 6-8 GYA, the frequency of nearby catastrophic events and often prolonged harsh environment may have strongly constrained life in the early history of the Milky Way. Active galactic nuclei (AGN) may remain quiescent for hundreds of millions of years only to activate for some time due extraordinary accretion episode due to for instance a galactic merger. The starburst galaxy M82 is currently undergoing a merger, probably strongly compromising habitability within that galaxy. The giant elliptical M87 resides in the center of the Virgo supercluster and has probably consumed many such spiral galaxies. We show that super-Eddington accretion onto the supermassive black hole in M87, even for a short while, could compromise the habitability for a large portion of the central supercluster. We discuss environments where these effects may be mitigated.

    Disordered bowel habits might influence quality of life after bariatric surgery. Different types of bariatric operations-gastric banding (AGB), Roux-en-Y gastric bypass (RYGB), or biliopancreatic diversion (BPD)-might alter bowel habits as a consequence of the surgical procedure used. Whether change in bowel habits affects quality of life after AGB, RYGB, or BPD differently is unknown. The study group contained 290 severely obese patients undergoing bariatric surgery between August 1996 and September 2004 [BPD: n = 103, 64.1% women, age 43 +/- 1 years (mean +/- SEM), BMI 53.9 +/- 0.9 kg/m(2), weight 153.4 +/- 2.9 kg; Roux-en-Y gastric bypass: n = 126, 73.0% women, age 43 +/- 1 years, BMI 44.2 +/- 0.3 kg/m(2), weight 123.8 +/- 1.5 kg; adjustable gastric banding (AGB): n = 61, 57.4% women, age 44 +/- 1 years, BMI 49.9 +/- 0.5 kg/m(2), weight 146.1 +/- 2.0 kg). Changes in bowel habits, flatulence, flatus odor, and effects on social life were estimated at least 4 months after surgery using a self-administered questionnaire. Fecal consistency changed significantly after surgery. Loose stools and diarrhea were more frequent after BPD and RYGB (P flatus affecting social life was more frequent after BPD than after either RYGB or AGB (P flatus frequency increased after BPD and RYGB, and patients were more bothered by their malodorous flatus than after AGB (all P Flatus severity score was highest in BPD, intermediate in RYGB, and lowest in AGB patients (all P < 0.001), a difference that was not influenced by frequency of metabolic syndrome before and after surgery. Moreover, observation period after surgery had no influence on overall results of bowel habits. Subsore quality of life bariatric analysis and reporting outcome system (BAROS) scores were largely similar between all three groups. However, flatulence severity score correlated inversely with quality of life estimated by BAROS in BPD and RYGB, but not in AGB patients. The type of bariatric surgery affects bowel

    Science.gov (United States)

    Warnock, Clare

    2014-07-15

    The breaking of bad news was traditionally regarded to be the time when a doctor and nurse sat down with a patient and family members to provide information about, for example, a life-limiting diagnosis or a poor prognosis. However, breaking bad news is now generally accepted as a process, not a one-off event, and is considered to refer to any bad, sad or difficult information that alters patients' perceptions of their present and future. Nurses have an important role in the process of providing information and helping patients prepare for, receive, understand and cope with the bad news they have been given. This article aims to help nurses understand the process of breaking bad news and discuss the challenges and difficulties that nurses can face when they are involved with patients who have been given bad news. It also provides guidance with regard to preparing for breaking bad news, giving difficult information, responding to possible reactions, and supporting patients and their relatives after they have received bad news.

  5. Influenza virus induces apoptosis via BAD-mediated mitochondrial dysregulation.

    2013-01-01

    Influenza virus infection results in host cell death and major tissue damage. Specific components of the apoptotic pathway, a signaling cascade that ultimately leads to cell death, are implicated in promoting influenza virus replication. BAD is a cell death regulator that constitutes a critical control point in the intrinsic apoptosis pathway, which occurs through the dysregulation of mitochondrial outer membrane permeabilization and the subsequent activation of downstream apoptogenic factors. Here we report a novel proviral role for the proapoptotic protein BAD in influenza virus replication. We show that influenza virus-induced cytopathology and cell death are considerably inhibited in BAD knockdown cells and that both virus replication and viral protein production are dramatically reduced, which suggests that virus-induced apoptosis is BAD dependent. Our data showed that influenza viruses induced phosphorylation of BAD at residues S112 and S136 in a temporal manner. Viral infection also induced BAD cleavage, late in the viral life cycle, to a truncated form that is reportedly a more potent inducer of apoptosis. We further demonstrate that knockdown of BAD resulted in reduced cytochrome c release and suppression of the intrinsic apoptotic pathway during influenza virus replication, as seen by an inhibition of caspases-3, caspase-7, and procyclic acidic repetitive protein (PARP) cleavage. Our data indicate that influenza viruses carefully modulate the activation of the apoptotic pathway that is dependent on the regulatory function of BAD and that failure of apoptosis activation resulted in unproductive viral replication.

    2016-06-01

    Although giving bad news at work is a stressful experience, managers are often underprepared for this challenging task. As a solution, we introduce organizational bad news training that integrates (a) principles of delivering bad news from the context of health care (i.e., bad news delivery component), and (b) principles of organizational justice theory (i.e., fairness component). We argue that both the formal and fair delivery of bad news at work can be enhanced with the help of training to mitigate distress both for the messenger and the recipient. We tested the effectiveness of training for the delivery of a layoff as a typical bad news event at work. In 2 studies, we compared the performance of a training group (receiving both components of training) with that of a control group (Study 1, Study 2) and a basics group (receiving the bad news delivery component only; Study 2) during a simulated dismissal notification meeting. In general, the results supported our hypotheses: Training improved the formal delivery of bad news and predicted indicators of procedural fairness during the conversation in both studies. In Study 2, we also considered layoff victims' negativity after the layoff and found that training significantly reduced negative responses. This relationship was fully mediated by layoff victims' fairness perceptions. Despite preparation, however, giving bad news remained a challenging task in both studies. In summary, we recommend that organizations provide managers with organizational bad news training in order to promote professional and fair bad news conversations at work.

    We describe a methodology for identifying asymmetries in boat hull sections reconstructed from point clouds captured using a terrestrial laser scanner (TLS). A surface was first fit to the point cloud using a nonparametric regression method that permitted the construction of a continuous smooth surface. Asymmetries in cross-sections of the surface were identified using a bootstrap resampling technique that took into account uncertainty in the coordinates of the scanned points. Each reconstructed section was analyzed to check, for a given level of significance, that it was within the confidence interval for the theoretical symmetrical section. The method was applied to the study of asymmetries in a medium-sized yacht. Identified were differences of up to 5 cm between the real and theoretical sections in some parts of the hull.

    Breaking bad news is a complex and frequent clinical task for physicians working in oncology. It can have a negative impact on patients and their relatives who are often present during breaking bad news consultations. Many factors influence how the delivery of bad news will be experienced especially the communication skills used by physicians. A three-phase process (post-delivery phase, delivery phase, pre-delivery phase) has been developed to help physician to handle this task more effectively. Communication skills and specific breaking bad news training programs are both necessary and effective. A recent study conducted in Belgium has shown their impact on the time allocated to each of the three phases of this process, on the communication skills used, on the inclusion of the relative in the consultation and on physicians' physiological arousal. These results underscore the importance of promoting intensive communication skills and breaking bad news training programs for health care professionals.

  15. The Natural Selection of Bad Science

    2016-01-01

    Poor research design and data analysis encourage false-positive findings. Such poor methods persist despite perennial calls for improvement, suggesting that they result from something more than just misunderstanding. The persistence of poor methods results partly from incentives that favor them, leading to the natural selection of bad science. This dynamic requires no conscious strategizing---no deliberate cheating nor loafing---by scientists, only that publication is a principle factor for career advancement. Some normative methods of analysis have almost certainly been selected to further publication instead of discovery. In order to improve the culture of science, a shift must be made away from correcting misunderstandings and towards rewarding understanding. We support this argument with empirical evidence and computational modeling. We first present a 60-year meta-analysis of statistical power in the behavioral sciences and show that power has not improved despite repeated demonstrations of the necessity...

    2017-03-02

    Adenosine is an endogenous ubiquitous purine nucleoside, increased by hypoxia, ischemia and tissue damage that mediates a number of physiopathological effects by interacting with four G-protein-coupled receptors, identified as A1 , A2A , A2B , and A3 . Physiological and acutely-increased adenosine is associated with beneficial effects mostly including vasodilation and decrease of inflammation. In contrast chronic overproduction of adenosine occurs in important pathological states, where long lasting increases in the nucleoside levels are responsible for the bad side of adenosine associated with chronic inflammation, fibrosis and organ damage. In this review we describe and critically discuss the pathologic overproduction of adenosine analysing when, where and how adenosine exerts its detrimental effects through the body.

    Dengue vector Aedes aegypti L. is invading peri-urban and rural areas throughout Latin America. Our previous research in the Peruvian Amazon has shown that river boats are heavily infested with immature and adult Ae. aegypti mosquitoes, likely playing a major role in their long-distance dispersal and successful invasion. However, the presence of immature mosquitoes provides no information about the timing of oviposition, and whether it took place in the boats. Here, we used baited ovitraps deployed on river boats to test the hypothesis that Ae. aegypti oviposition occurs during boat travel. We deployed 360 ovitraps on 60 different barges during August and October of 2013, and February 2014 (with 20 barges sampled during each month). We found that Ae. aegypti mosquitoes in 22 individual ovitraps from 15 of the 60 barges (premise index 25%) across all sampling dates. Further, the distribution of Ae. aegypti egg abundance was highly aggregated: 2.6% of traps (N=7) were responsible for 71.8% of eggs found, and 1.5% of traps (N=4) were responsible for all (100%) of the larvae found. Similarly, 5% of boats were responsible for the 71.47% of eggs. Our results provide strong evidence that Ae. aegypti oviposition commonly occurs during boat travel. Baited ovitraps could represent a cost-effective means of monitoring and controlling mosquito populations on boats.

  20. Widen the Belt of Habitability!

    Science.gov (United States)

    Möhlmann, D.

    2012-06-01

    Among the key-parameters to characterize habitability are presence or availability of liquid water, an appropriate temperature range, and the time scale of reference. These criteria for habitability are discussed and described from the point of view of water- and ice-physics, and it is shown that liquid water may exist in the sub-surfaces of planetary bodies like Mars, and possibly of inner asteroids and internally heated ice-moons. Water can remain fluid there also at temperatures far below the "canonical" 0 °C. This behaviour is made possible as a consequence of the freezing point depression due to salty solutes in water or "brines", as they can be expected to exist in nature more frequently than pure liquid water. On the other hand, low temperatures cause a slowing down of chemical processes, as can be described by Arrhenius's relation. The resulting smaller reaction rates probably will have the consequence to complicate the detection of low-temperature life processes, if they exist. Furthermore, the adaptation potential of life is to be mentioned in this context as a yet partially unknown process. Resulting recommendations are given to improve the use of criteria to characterize habitable conditions.

    Background Habit is defined as a process whereby an impulse towards behaviour is automatically initiated upon encountering a setting in which the behaviour has been performed in the past. A central tenet of habit theory is that habit overrides intentional tendencies in directing behaviour, such that as habit strength increases, intention becomes less predictive of behaviour. Yet, evidence of this effect has been methodologically limited by modelling the impact of positively-correlated habits ...

    Full Text Available Three decades ago Detlev Ellmers suggested that hide (skin boats were being used to hunt swimming reindeer in glacial lakes of northern Germany's Upper Palaeolithic. This paper presents new material in support of Ellmers' contention. A paleo-osteological study from Stellmoor suggests that arrows were directed at the neck and upper shoulders from above and behind, at close range which can be considered evidence of them being shot by hunters in boats as the animals were swimming. Lyngby axes are linked to this hunting technique which provides possible distribution and dating for this proposed early boat technology.

    The aim of the study was to assess postural habits in young, healthy people, identify correlations between postural errors and pain and attempt to modify bad habits. 144 people, aged 18-23 were enrolled. The intervention consisted of 4 stages: Stage 1 - identification of postural habits, description of responses to stress, back pain frequency and intensity (Jackson & Moskowitz); Stage 2 - correction of habitual position with the help of a physiotherapist, briefing about ergonomic everyday behaviours and consequences of continued non-ergonomic behaviours, Stage 3 - follow-up examination: self-assessment of changes, evaluation of the effects of modifications, determination of causes for discontinuing the behaviour modification programme, where applicable; and Stage 4 - final examination, assessment of results. Correlations were sought between inappropriate postural behaviour in various positions and between non-ergonomic postural behaviour and pain location and response to stress. Statistical analysis was carried out with Excel and Statistica v. 7.1. A non-parametric χ(2) test was used at ppostural patterns in the standing, sitting and recumbent position. Back pain was reported by half of the participants. Statistically significant relationships between pain and habitual positions were noted with regard to the cervical and lumbar spine and also for abdominal pain as a response to stress in people with excessive thoracic kyphosis. Behaviour modifications caused or intensified lumbar pain or thigh muscle pain. Positive outcomes included better urination and/or defecation and greater comfort in assuming the different positions and performing activities of daily living in these positions. Some examinees discontinued behaviour modification during the first month after the initial instruction and the majority did so over the next three months. 1. Non-ergonomic postural behaviours are common among young people. 2. Changing the body position does not eliminate the impact of

    Banana boat rides are a popular form of recreation worldwide. Recommendations that speed should not exceed 15 mph, passengers should wear protective gear, and an observer should be present on the towing boat are generally ignored. Medical personnel at tourist venues and general practitioners may not be attuned to the risk of serious injury. We present our experience in the management carotid- and vertebral artery dissections sustained by 44- and 23-year-old males during banana boat rides. In both cases, the dissections were misdiagnosed until patients presented to the Emergency Department two days after injury. In the first patient, medical management failed and endovascular treatment was required due to neurological deterioration. In patient two, anticoagulation therapy prevented embolic sequelae. Boat operators, passengers, and the medical personnel who are first to see these patients should be aware of the risk of arterial dissection to facilitate early detection of these potentially life-threatening injuries.

    2015-01-01

    Full Text Available In this paper authors develop and research system for motor boat control, that allows to move along the stated paths with the given speed. It is assumed, that boat is equipped by the measuring system that provides current coordinates, linear and angular velocities. Control system is based upon the mathematical model, presented earlier (see references. In order to analytically find the necessary controls, all equations were transformed to Jordan controllable form. Besides solution this transformation also allows to handle model nonlinearities and get required quality of movement along the stated paths. Control system includes algorithms for control of longtitudal velocity and boat course. Research of the proposed control system according to boat design limitations for the values of control variables was performed by simulation in MATLAB. Results of two experiments, different in value of the required velocity are discussed.

    Early childhood is an important stage of physical growth and intellectual development of young children, and a good diet is important to ensure that young children's healthy development, and poor eating habits not only affect the child's physical health, but also may lead to the formation of bad habits children. This paper describes the children's partial eclipse, do not eat on time to snack instead of dinner and other forms of bad eating habits, in-depth analysis of the causes of poor chil-dren eating habits, and made specific recommendations to foster children's good eating habits.%幼儿时期是幼儿身体发育和智力发展的重要阶段,良好的饮食习惯是幼儿身体健康发展的重要保证,而不良的饮食习惯不仅会影响幼儿的身体健康,还可能导致幼儿形成不良的生活习惯。本文阐述了幼儿偏食、不按时进餐、以零食代替正餐等不良饮食习惯的表现形式,深入剖析了幼儿不良饮食习惯的成因,并提出了培养幼儿良好饮食习惯的具体建议。

  11. Cycle of Bad Governance and Corruption

    Directory of Open Access Journals (Sweden)

    Mohammed Nuruddeen Suleiman

    2015-03-01

    Full Text Available This article argues that bad governance and corruption particularly in the Northern part of Nigeria have been responsible for the persistent rise in the activities of Jama’atu Ahlis Sunna Lidda’awati wal-Jihad (JASLWJ, Arabic for “people committed to the propagation of the tradition and jihad.” It is also known as “Boko Haram,” commonly translated as “Western education is sin.” Based on qualitative data obtained through interviews with Nigerians, this article explicates how poor governance in the country has created a vicious cycle of corruption, poverty, and unemployment, leading to violence. Although JASLWJ avows a religious purpose in its activities, it takes full advantage of the social and economic deprivation to recruit new members. For any viable short- or long-term solution, this article concludes that the country must go all-out with its anti-corruption crusade. This will enable the revival of other critical sectors such as agriculture and manufacturing, likely ensuring more employment. Should the country fail to stamp out corruption, it will continue to witness an upsurge in the activities of JASLWJ, and perhaps even the emergence of other violent groups. The spillover effects may be felt not only across Nigeria but also within the entire West African region.

  12. Scientific disintegrity as a public bad.

    Science.gov (United States)

    Engel, Christoph

    2015-05-01

    In this article, I argue that scientific dishonesty essentially results from an incentive problem; I do so using a standard economic model-the public bad. Arguably, at least in the short run, most scientists would increase their personal utility by being sloppy with scientific standards. Yet, if they do, it becomes more difficult for all scientists to make their voice heard in society, to convince policy makers to assign public funds to academia, and to lead fulfilling academic lives. The nature of the ensuing governance problem (and appropriate policy intervention) hinges on the definition of scientists' utility function. The policy problem is less grave if society attaches disproportionally more weight to severe or widespread violations and if individual scientists do not precisely know in advance when they will quit their academic lives. If most scientists internalize most scientific standards, then the problem is alleviated. However, internalization is immaterial if honorable scientists dislike that others advance their careers by violating those standards. Sanctions are helpful, even if relatively mild. However, it is important to also punish those who do not punish others for breaking the rules or, alternatively, to put some centralized mechanism for vigilance and enforcement into place.

  13. The natural selection of bad science.

    Smaldino, Paul E; McElreath, Richard

    2016-09-01

    Poor research design and data analysis encourage false-positive findings. Such poor methods persist despite perennial calls for improvement, suggesting that they result from something more than just misunderstanding. The persistence of poor methods results partly from incentives that favour them, leading to the natural selection of bad science. This dynamic requires no conscious strategizing-no deliberate cheating nor loafing-by scientists, only that publication is a principal factor for career advancement. Some normative methods of analysis have almost certainly been selected to further publication instead of discovery. In order to improve the culture of science, a shift must be made away from correcting misunderstandings and towards rewarding understanding. We support this argument with empirical evidence and computational modelling. We first present a 60-year meta-analysis of statistical power in the behavioural sciences and show that power has not improved despite repeated demonstrations of the necessity of increasing power. To demonstrate the logical consequences of structural incentives, we then present a dynamic model of scientific communities in which competing laboratories investigate novel or previously published hypotheses using culturally transmitted research methods. As in the real world, successful labs produce more 'progeny,' such that their methods are more often copied and their students are more likely to start labs of their own. Selection for high output leads to poorer methods and increasingly high false discovery rates. We additionally show that replication slows but does not stop the process of methodological deterioration. Improving the quality of research requires change at the institutional level.

  14. Host Star Evolution for Planet Habitability

    2016-11-01

    With about 2000 exoplanets discovered within a large range of different configurations of distance from the star, size, mass, and atmospheric conditions, the concept of habitability cannot rely only on the stellar effective temperature anymore. In addition to the natural evolution of habitability with the intrinsic stellar parameters, tidal, magnetic, and atmospheric interactions are believed to have strong impact on the relative position of the planets inside the so-called habitable zone. Moreover, the notion of habitability itself strongly depends on the definition we give to the term "habitable". The aim of this contribution is to provide a global and up-to-date overview of the work done during the last few years about the description and the modelling of the habitability, and to present the physical processes currently includes in this description.

    CERN Document Server

    Cockell, Charles S

    2013-01-01

    'Most habitable worlds in the cosmos will have no remotely detectable signs of life' is proposed as a biological hypothesis to be tested in studies of exoplanets. Habitable planets could be discovered elsewhere in the Universe, yet there are many hypothetical scenarios whereby the search for life on them could yield negative results. Scenarios for habitable worlds with no remotely detectable signatures of life include: planets that are habitable, but have no biosphere (Uninhabited Habitable Worlds); planets with life, but lacking any detectable surface signatures of that life (laboratory examples are provided) and planets with life, where the concentration of atmospheric gases produced or removed by biota are impossible to disentangle from abiotic processes because of the lack of detailed knowledge of planetary conditions (the 'problem of exoplanet thermodynamic uncertainty'). A rejection of the hypothesis would require that the origin of life usually occurs on habitable planets, that spectrally detectable pi...

  16. Dietary habits and esophageal cancer.

    2015-01-01

    Cancer of the esophagus is an underestimated, poorly understood, and changing disease. Its overall 5-year survival is less than 20%, even in the United States, which is largely a function of a delay in diagnosis until its more advanced stages. Additionally, the epidemiologic complexities of esophageal cancer are vast, rendering screening and prevention limited at best. First, the prevalence of esophageal cancer is unevenly distributed throughout the world. Second, the two histological forms (squamous cell and adenocarcinoma) vary in terms of their geographic prevalence and associated risk factors. Third, some populations appear at particular risk for esophageal cancer. And fourth, the incidence of esophageal cancer is in continuous flux among groups. Despite the varied prevalence and risks among populations, some factors have emerged as consistent associations while others are only now becoming more fully recognized. The most prominent, scientifically supported, and long-regarded risk factors for esophageal cancer are tobacco, alcohol, and reflux esophagitis. Inasmuch as the above are regarded as important risk factors for esophageal cancer, they are not the sole contributors. Dietary habits, nutrition, local customs, and the environment may be contributory. Along these lines, vitamins, minerals, fruits, vegetables, meats, fats, salted foods, nitrogen compounds, carcinogens, mycotoxins, and even the temperature of what we consume are increasingly regarded as potential etiologies for this deadly although potentially preventable disease. The goal of this review is to shed light on the less known role of nutrition and dietary habits in esophageal cancer.

  17. Tidal Limits to Planetary Habitability

    CERN Document Server

    Barnes, Rory; Greenberg, Richard; Raymond, Sean N

    2009-01-01

    The habitable zones of main sequence stars have traditionally been defined as the range of orbits that intercept the appropriate amount of stellar flux to permit surface water on a planet. Terrestrial exoplanets discovered to orbit M stars in these zones, which are close-in due to decreased stellar luminosity, may also undergo significant tidal heating. Tidal heating may span a wide range for terrestrial exoplanets and may significantly affect conditions near the surface. For example, if heating rates on an exoplanet are near or greater than that on Io (where tides drive volcanism that resurface the planet at least every 1 Myr) and produce similar surface conditions, then the development of life seems unlikely. On the other hand, if the tidal heating rate is less than the minimum to initiate plate tectonics, then CO_2 may not be recycled through subduction, leading to a runaway greenhouse that sterilizes the planet. These two cases represent potential boundaries to habitability and are presented along with th...

  2. Breaking bad news: A communication competency for ophthalmology training programs.

    Science.gov (United States)

    Hilkert, Sarah M; Cebulla, Colleen M; Jain, Shelly Gupta; Pfeil, Sheryl A; Benes, Susan C; Robbins, Shira L

    As the ophthalmology accreditation system undergoes major changes, training programs must evaluate residents in the 6 core competencies, including appropriately communicating bad news. Although the literature is replete with recommendations for breaking bad news across various non-ophthalmology specialties, no formal training programs exist for ophthalmology. There are many valuable lessons to be learned from our colleagues regarding this important skill. We examine the historic basis for breaking bad news, explore current recommendations among other specialties, and then evaluate a pilot study in breaking bad news for ophthalmology residents. The results of this study are limited by a small number of residents at a single academic center. Future studies from multiple training programs should be conducted to further evaluate the need and efficacy of formal communication skills training in this area, as well as the generalizability of our pilot training program. If validated, this work could serve as a template for future ophthalmology resident training and evaluation in this core competency.

    2002-09-01

    Previous research has shown that physicians experience incompetence and difficulty in dealing with patients' feelings after they have broken bad news to them. During the past 10 years, we have implemented a longitudinal training program targeting these issues. The present article describes this training and discusses its contribution to doctors' skills at approaching distressed patients. In order to cope with breaking bad news to patients and their families, physicians should be skilled at crisis intervention and communication techniques. They should also be aware of their personal attitudes and emotional reactions when breaking bad news. Each session encompassed these areas, as well as the most prominent issues arising when breaking bad news. In a 1-5 Likert scale, the course received an overall score of 4.47 (S.D. 0.51). Participants noted that they had gained relevant communication skills for future patient encounters.

  8. CONTROLLING RISK DUE TO NOISE ON FERRY BOAT

    Directory of Open Access Journals (Sweden)

    Aleksandar Nikolic

    2013-07-01

    Full Text Available Environmental and occupational noise is common nuisance that affects the health of employees. Performed health checks of employees engaged by Company “Pomorski Saobraćaj” showed that 5% of examined sailors had hearing loss. The results were a trigger for starting experiment on noise risk assessment with objective to discover possibilities of noise pollution presence, precise significant noise sources and describe solutions for eliminating negative effects. Several measurements on five positions were performed on ferry boat “KAMENARI”, according to EC Physical Agents Directive and Merchant Shipping and Fishing Vessels Regulations 2007. Noise on selected positions exceeded the limit for about 1-5dB. Noise exposure level was 84.5dB. Diesel engine, exhaust system and structural noise were main sources of excessive noise. Experiment shows noise presence as nuisance that affects sailors. Noise presents a serious threat for sailor’s health. It interferes with crew communication and jeopardizes navigation safety. Technical measures, crew health checks and noise monitoring could prevent all negative effects.

  9. The big crossing: illegal boat migrants in the Mediterranean.

    Science.gov (United States)

    Kassar, Hassène; Dourgnon, Paul

    2014-08-01

    This article explores illegal migration routes and groups across North Africa to Europe. We describe sub-Saharan and cross-Mediterranean routes, and how they changed during the years. We propose an analytical framework for the main factors for these migrations, from local to international and regulatory context. We then describe sea-migrants' nationalities and socio-economic and demographic characteristics, from studies undertook in Tunisia and Morocco. While boat migration represents only a fraction of illegal migration to Europe, it raises humanitarian as well as ethical issues for European and North African (NA) countries, as a non-negligible amount of them end up in death tolls of shipwrecks in the Mediterranean Sea. Moreover, existing statistics show that illegal trans-Mediterranean migration is growing exponentially. Ongoing crises in Africa and the Middle East are likely to prompt even larger outflows of refugees in the near future. This should induce NA countries to share closer public policy concerns with European countries.

  13. Bad Apples, Bad Barrel: Exploring Institutional Responses to Child Sexual Abuse by Catholic Clergy in Australia

    Directory of Open Access Journals (Sweden)

    Jodi Death

    2015-07-01

    Full Text Available This paper considers constructions of institutional culture and power in the cover-up of child sexual abuse (CSA by clergy in the Roman Catholic Church of Australia. The issue of cover-up has previously been considered in international inquiries as an institutional failing that has caused significant harm to victims of CSA by Catholic Clergy. Evidence given by select representatives of the Catholic Church in two government inquiries into institutional abuse carried out in Australia is considered here. This evidence suggests that, where cover-up has occurred, it has been reliant on the abuse of institutional power and resulted in direct emotional, psychological and spiritual harm to victims of abuse. Despite international recognition of cover-up as institutional abuse, evidence presented by Roman Catholic Representatives to the Victorian Inquiry denied there was an institutionalised cover-up. Responding to this evidence, this paper queries whether the primary foundation of cover-up conforms to the ‘bad apple theory’ in that it relates only to a few individuals, or the ‘bad barrel theory’ of institutional structure and culture.

  14. Tides, planetary companions, and habitability: Habitability in the habitable zone of low-mass stars

    CERN Document Server

    Van Laerhoven, Christa; Greenberg, Richard

    2014-01-01

    Earth-scale planets in the classical habitable zone (HZ) are more likely to be habitable if they possess active geophysics. Without a constant internal energy source, planets cool as they age, eventually terminating tectonic activity and rendering the planet sterile to life. However, for planets orbiting low-mass stars, the presence of an outer companion could generate enough tidal heat in the HZ planet to prevent such cooling. The range of mass and orbital parameters for the companion that give adequate long-term heating of the inner HZ planet, while avoiding very early total desiccation, is probably substantial. We locate the ideal location for the outer of a pair of planets, under the assumption that the inner planet has the same incident flux as Earth, orbiting example stars: a generic late M dwarf ($T_{eff}=2670 K$) and the M9V/L0 dwarf DEN1048. Thus discoveries of Earth-scale planets in the HZ zone of old small stars should be followed by searches for outer companion planets that might be essential for ...

  15. Why good accountants do bad audits.

    Science.gov (United States)

    Bazerman, Max H; Loewenstein, George; Moore, Don A

    2002-11-01

    On July 30, President Bush signed into law the Sarbanes-Oxley Act addressing corporate accountability. A response to recent financial scandals, the law tightened federal controls over the accounting industry and imposed tough new criminal penalties for fraud. The president proclaimed, "The era of low standards and false profits is over." If only it were that easy. The authors don't think corruption is the main cause of bad audits. Rather, they claim, the problem is unconscious bias. Without knowing it, we all tend to discount facts that contradict the conclusions we want to reach, and we uncritically embrace evidence that supports our positions. Accountants might seem immune to such distortions because they work with seemingly hard numbers and clear-cut standards. But the corporate-auditing arena is particularly fertile ground for self-serving biases. Because of the often subjective nature of accounting and the close relationships between accounting firms and their corporate clients, even the most honest and meticulous of auditors can unintentionally massage the numbers in ways that mask a company's true financial status, thereby misleading investors, regulators, and even management. Solving this problem will require far more aggressive action than the U.S. government has taken thus far. What's needed are practices and regulations that recognize the existence of bias and moderate its effects. True auditor independence will entail fundamental changes to the way the accounting industry operates, including full divestiture of consulting and tax services, rotation of auditing firms, and fixed-term contracts that prohibit client companies from firing their auditors. Less tangibly, auditors must come to appreciate the profound impact of self-serving biases on their judgment.

    Science.gov (United States)

    Spohn, Tilman; Breuer, Doris

    2016-04-01

    The role of plate tectonics in defining habitability of terrestrial planets is being increasingly discussed (e.g., Elkins-Tanton, 2015). Plate tectonics is a significantly evolved concept with a large variety of aspects. In the present context, cycling of material between near surface and mantle reservoirs is most important. But increased heat transport through mixing of cold lithosphere with the deep interior and formation of continental crust may also matter. An alternative mechanism of material cycling between these reservoirs is hot-spot volcanism combined with crust delamination. Hot-spot volcanism will transport volatiles to the atmosphere while delamination will mix crust, possibly altered by sedimentation and chemical reactions, with the mantle. The mechanism works as long as the stagnant lithosphere plate has not grown thicker than the crust and as long as volcanic material is added onto the crust. Thermal evolution studies suggest that the mechanism could work for the first 1-2 Ga of planetary evolution. The efficiency of the mechanism is limited by the ratio of extrusive to intrusive volcanism, which is thought to be less than 0.25. Plate tectonics would certainly have an advantage by working even for more evolved planets. A simple, most-used concept of habitability requires the thermodynamic stability of liquid water on the surface of a planet. Cycling of CO2between the atmosphere, oceans and interior through subduction and surface volcanism is an important element of the carbonate-silicate cycle, a thermostat feedback cycle that will keep the atmosphere from entering into a runaway greenhouse. Calculations for a model Earth lacking plate tectonics but degassing CO2, N, and H2O to form a surface ocean and a secondary atmosphere (Tosi et al, 2016) suggest that liquid water can be maintained on the surface for 4.5Ga. The model planet would then qualify as habitable. It is conceivable that the CO2 buffering capability of its ocean together with silicate

  20. Habitability Properties of Circumbinary Planets

    Science.gov (United States)

    Shevchenko, Ivan I.

    2017-06-01

    It is shown that several habitability conditions (in fact, at least seven such conditions) appear to be fulfilled automatically by circumbinary planets of main-sequence stars (CBP-MS), whereas on Earth, these conditions are fulfilled only by chance. Therefore, it looks natural that most of the production of replicating biopolymers in the Galaxy is concentrated on particular classes of CBP-MS, and life on Earth is an outlier, in this sense. In this scenario, Lathe’s mechanism for the tidal “chain reaction” abiogenesis on Earth is favored as generic for CBP-MS, due to photo-tidal synchronization inherent to them. Problems with this scenario are discussed in detail.

    Sleep is generally regarded as a valuable resource for psychological and physiological well-being. Although the effects of sleep on athletic performance have been acknowledged in sport science, few studies have investigated the prevalence of sleep problems and their effects on elite athletes before a sport event. In this study, 632 German athletes from various sports were asked about their sleep habits during the night(s) before an important competition or game. The findings indicate that 65.8% of the athletes experienced poor sleep in the night(s) before a sports event at least once in their lives and a similarly high percentage (62.3%) had this experience at least once during the previous 12 months. Athletes of individual sports reported more sleep difficulties than athletes of team sports. The main sleep problem was not being able to fall asleep. Internal factors such as nervousness and thoughts about the competition were rated highest for causing sleep problems. Most athletes stated that disturbed sleep had no influence on their athletic performance; however, athletes also reported effects such as a bad mood the following day, increased daytime sleepiness, and worse performance in the competition or game. The differences between individual and team sports indicate that athletes in some sports need more help than those in other sports in managing sleep problems.

    Mesosauridae comprises the oldest known aquatic amniotes which lived in Gondwana during the Early Permian. Previous work in the Uruguayan mesosaur-bearing Mangrullo Formation suggested that mesosaurids lived in an inland water body, inferred as moderately hypersaline, with exceptional preservational conditions that justified describing these strata as a Fossil-Lagerstätte. Exquisitely preserved articulated mesosaur skeletons, including gastric content and associated coprolites, from the Brazilian Iratí Formation in the State of Goiás (central-western Brazil) indicate excellent conditions of preservation, extending the Konservat-Lagerstätte designation to both units in the Paraná Basin. The near-absence of more resistant fossil remains, like actinopterygian and temnospondyl bones, demonstrates the faunistic poverty of the mesosaur-bearing “salty sea”. Our studies of the alimentary habits of mesosaurids through the use of stereoscopic microscopy, light and electronic microscopy, and X-ray diffractometry suggest that the diet of mesosaurids was predominantly composed of pygocephalomorph crustaceans (possibly not exceeding 20 mm in length). However, the presence of bones and bone fragments of small mesosaurs in the gastric content, cololites, coprolites, and possible regurgitalites may also indicate cannibalistic and/or scavenging habits. Cannibalism is relatively common among vertebrates, particularly during conditions of environmental stress, like food shortage. Likewise, the apparent abundance of pygocephalomorph crustacean fossils in the Iratí and Mangrullo Formations, outside and within the studied gastric, cololite, and coprolite contents, might have to do with environmental stress possibly caused by volcanic activity, in particular ash spread into the basin during the Early Permian. In this context, casual necrophagy on the dead bodies of small mesosaurs and large pygocephalomorphs might have been an alternative alimentary behavior adopted for survival

    Full Text Available To ensure the fishing boat security in the coastal area of Fujian, it is imperative to develop efficient forecasting control system to manage the boats operation in a safe and orderly process. The core issue of establishing the forecasting control system is to predict the relationship of the real time traffic flow and the boat security condition. However, literature review shows that limited reports have addressed on this problem. Hence, a new intelligent forecasting control method base on the Chaos-Particle Swarm Optimization (PSO and Fuzzy Neural Network (FNN is proposed for the short time traffic flow prediction in this paper. The Empirical Mode Decomposition (EMD was first used to denoise the original ship traffic flow observation and then the Chaos-PSO-FNN was applied to the forecasting of the ship traffic flow and hence established the relationship of the real time traffic flow and the boat security condition. The advantage of the proposed approach is that the Chaos-PSO is employed to optimize the FNN parameters to overcome the premature problem of the FNN. As a result, the forecasting control performance is enhanced greatly. In the experiment analysis, the fishing boat traffic information provided by the Fujian marine bureau has been used to evaluate the newly proposed method. The analysis results demonstrate that the proposed Chaos-PSO-FNN method can extract distinct features of the traffic data and the prediction rate is beyond 93.7%. In addition, it found that the fishing boats is supposed to be safe when their travel time avoids the rush time of the traffic flow. This result agrees well with the real data. Thus, the new intelligent forecasting control method for fishing boat security can be used in practice.

    To determine the prevalence of sleep disorders in adolescence. To describe sleeping habits of adolescents in relation to sleep disorders and associated factors. To determine the relation between sleep disorders/inappropiate sleeping habits and school performance. Observational, descriptive, cross-sectional study. Secondary school of Cuenca (city in Spain). 1293 school children of first and fourth curses of secondary education. Structured questionnaire with opened and closed questions on sleeping habits during weekdays and at weekends and sleep disorders to be answered by the adolescents anonymously and on their own. Student's school performance with relation with to sleeping habits and sleep disorders were determined. 1155 students out of 1293 (response rate 89.33%) answered the questionnaire, 537 (45.9%) boys and 618 (54.1%) girls, 14 years old on average (between 11-18 years). On weekdays students went to bed at 23.17 h and got up at 7.46 h (average sleeping time =8 hours and 18 minutes). At weekends they went to bed at 1.02 h and got up at 10.42 h (average sleeping time =9 hours and 40 minutes). 45.4% of students said to sleep badly on Sunday night's. On average the number of subjects failed in class is higher with adolescents who complain about sleep (2.28 vs 1.91; P=.04), who are tired at waking up time (2.17 vs 1.97; P=.048) and who have morning sleepiness (2.17 vs 1.75; P=.004). Schools hours cause deficit sleeping time during weekdays which is partly made up for at weekend. At weekends there is an interruption of the adolescent's sleeping habits. School performance of adolescents with sleep disorders is lower.

    This report presents towing tests made in the N.A.C.A. tank of a parent form and five variations of a flying-boat hull. The beams of two of the derived forms were made the same as that of the parent and the lengths changed by increasing and decreasing the spacing of stations. The lengths of the two others of the derived forms were made the same as that of the parent while the beams were changed by increasing and decreasing the spacing of buttocks, all other widths being changed in proportion. The remaining derived form has the same length and beam as the parent, but the lines of the forebody were altered to give a planing bottom with no longitudinal curvature forward of the step. The test data were analyzed to determine the minimum resistance and the angle at which it occurs for all speeds and loads. The results of this analysis are given in the form of non dimensional curves for each model. The effect of variation in over-all size, as indicated by a "complete" test on any given hull, is pointed out. The effect of changing length alone by the spacing of buttocks, as well as the effects of the changes in length-beam ratio and longitudinal curvature that result from these operations are discussed. The difficulties encountered in interpreting test results of systematic families derived by the method used are emphasized. Further studies are suggested in which changes in the variable under consideration would not be obscured by secondary changes in other important variables.

    Full Text Available This paper activates a mode of spatial inquiry into Australia’s identity through an analysis of a number of frames through which the passage and interdiction of boats off the coast of the nation may be viewed. In particular, I explore the way in which Australia’s paradoxical geographical location as South of both the West and Asia play a key role in affixing the horizon within which a conception of the nation and its relationship with the world was – and continues to be – defined and shaped. Moreover, I not only critically probe the constitutive fears and anxieties that underlie bounded conceptions of the trope of the South, but also to examine how such a trope can articulate itself as a site of exchange and negotiation, a distinctive borderland that engenders new cartographies of difference and belonging in an increasingly globalised and interconnected world. I show how these frames overlap and converge on the wider questions of space, place and identity at the very moment when the process of globalisation and migration has done so much to shake any certainties about Australia’s identity as a geographically distinct and spatially bounded nation-state. In so doing, they represent crucial sites for articulating and enacting a transcultural politics of mobility and spatiality that attends to the ways in which the trope of the South may been imagined not as a sphere of containment or an enclaved territory, but as an evolving cartography, the shifting outlines of which opens up new horizons of possibility for rethinking the spatial and temporal coordinates of Australia in a globalizing world.

  8. Boat's hull modeling with low-cost triangulation scanners

    In a 3D acquisition project range maps collected around the object to be modeled, need to be integrated. With portable range cameras these range maps are taken from unknown positions and their coordinate systems are local to the sensor. The problem of unifying all the measurements in a single reference system is solved by taking contiguous range maps with a suitable overlap level; taking one map as reference and doing a rototranslation of the adjacent ones by using an "Iterative Closest Point" (ICP) method. Depending on the 3D features over the acquired surface and on the amount of overlapping, the ICP algorithm convergence can be more or less satisfactory. Anyway it always has a random component depending on measurement uncertainty. Therefore, although each individual scan has a very good accuracy, the error's propagation may produce deviations in the aligned set respect to real surface points. In this paper a systematic study of the different alignment modality and the consequent total metric distortions on the final model, is shown. In order to experiment these techniques a case-study of industrial interest was chosen: the 3D modeling of a boat's hull mold. The experiments involved a triangulation based laser scanner integrated with a digital photogrammetry system. In order to check different alignment procedures, a Laser Radar capable to scan all the object surface with a single highly accurate scan, was used to create a "gold-standard" data set. All the experiments were compared with this reference and from the comparison several interesting methodological conclusions have been obtained.

  9. The May 2015 boat crisis: the Rohingya in Aceh

    Full Text Available Abstract In May 2015, Indonesia permitted the disembarkation of approximately 1,800 people who had been stranded at sea. The discovery of mass graves in Thailand’s Sadao district, on the border with Malaysia, led to a crack down on people smugglers by the Thai and Malaysian authorities. This saw thousands of Rohingya left stranded at sea as smugglers abandoned their human cargo. While initially pushed back by the Indonesian navy, after being rescued by Indonesian fishermen the Rohingya, on the three boats rescued, were permitted to stay in Indonesia’s Aceh province and seek protection. As part of an Amnesty International research team, conducting research in Aceh in August 2015, our aim was to document the reasons driving the Rohingya to leave Myanmar and Bangladesh, the human rights abuses they experienced at sea and the conditions they are experiencing in Aceh. The subsequent Amnesty International report primarily documented the abuses suffered by those on board the smuggling/trafficking vessels. It also highlighted a number of issues now facing those allowed to remain in Aceh (Amnesty International, 2015. This article will further examine the human rights situation facing the Rohingya in Aceh, why they have been treated differently from previous Rohingya groups who have arrived in Aceh and the ongoing sustainability of the current model. Significantly, the majority of those that arrived have subsequently escaped from the “sites”[1], having again engaged smugglers to reach Malaysia. Given that a process already exists for refugees arriving in Indonesia, the differing treatment received by the Rohingya arriving in May 2015 raises a number of questions. This paper will conclude that the current situation is not sustainable and the treatment of refugees in Aceh should be included in a broader national approach commensurate to the treatment of refugees and asylum seekers throughout Indonesia.

Recent evidences indicate that patients' and physicians' attitude toward breaking bad news has been changed since few years ago. The evidence of breaking bad news is different across cultures. The aim of this study is to evaluate the attitude of medical staff toward breaking bad news to provide a clinical guideline in Iran."nMethods: A descriptive study was conducted during 2008-2009 on a sample of 100 medical staff (50 physicians and 50 nurses at Cancer Institute of Imam Khomeini hospital. The subjects' demographic characteristics and their attitudes toward the manner of revealing the diagnosis were registered in a questionnaire."nResults: The majority of the physicians (86%, n=43 and nurses (74%, n=37 , mostly the older and more experienced, tended to reveal the diagnosis to patients . Only a few physicians (8%, n=4 had been trained how to disclose bad news, which discloused diagnosis more than non trained ones."nPhysicians and nurses preferred to inform the patients about the diagnosis when either the patients were alone or in the presence of their spouse respectively .Only a few physicians (14% and nurses (24% agreed to explain life expectancy to patients."nConclusion: Compared to past, physicians and nurses are more willing to share cancer diagnosis with patients. However, lack of adequate communication skills in caregivers, and their concerns about managing patients' emotional reactions reduce their tendency to disclose bad news to the patients. Therefore, training physicians and nurses to expose bad news to the patients seems to be necessary.

  16. The Impact of "Bad" Argo Profiles on Ocean Data Assimilation

    2010-01-01

    Recent studies have found cold biases in a fraction of Argo profiles (hereinafter referred to as bad Array for Real-time Geostrophic Oceanography (Argo) profiles) due to the pressure drifts during 2003 and 2006. These bad Argo profiles have had an important impact on in situ observation-based global ocean heat content estimates. This study investigated the impact of bad Argo profiles on ocean data assimilation results that were based on observations from diverse ocean observation systems, such as in situ profiles (e.g., Argo, expendable bathythermograph (XBT), and Tropical Atmosphere Ocean (TAO), remote-sensing sea surface temperature products and satellite altimetry between 2004 and 2006. Results from this work show that the upper ocean heat content analysis is vulnerable to bad Argo profiles and demonstrate a cooling trend in the studied period despite the multiple independent data types that were assimilated. When the bad Argo profiles were excluded from the assimilation, the decreased heat content disappeared and a warming occurred. Combination of satellite altimetry and mass variation data from gravity satellite demonstrated an increase, which agrees well with the increased heat content. Additionally, when an additional Argo profile quality control procedure was utilized that simply removed the profiles that presented static unstable water columns, the results were very similar to those obtained when the bad Argo profiles were excluded from the assimilation. This indicates that an ocean data assimilation that uses multiple data sources with improved quality control could be less vulnerable to a major observation system failure, such as a bad Argo event.

    2011-08-01

    Habit formation is an important goal for behaviour change interventions because habitual behaviours are elicited automatically and are therefore likely to be maintained. This study documented experiences of habit development in 10 participants enrolled on a weight loss intervention explicitly based on habit-formation principles. Thematic analysis revealed three themes: Strategies used to support initial engagement in a novel behaviour; development of behavioural automaticity; and selecting effective cues to support repeated behaviour. Results showed that behaviour change was initially experienced as cognitively effortful but as automaticity increased, enactment became easier. Habits were typically formed in work-based contexts. Weekends and vacations temporarily disrupted performance due to absence of associated cues, but habits were reinstated on return to work. Implications for theory and practice are discussed.

    Where should we search for life in the universe? Habitable zones are traditionallydetermined based on the possibility of liquid water existing on a planet but ultraviolet (UV) radiation also plays a key role.The UV Habitable ZoneSchematic showing how the traditional habitable zones location and width changes around different types of stars. The UV habitable zone also hasdifferent locations and widths depending on the mass and metallicity of the star. [NASA/Kepler Mission/Dana Berry]Besides the presence of liquid water, there are other things life may need to persist. For life as we know it, one important elementis moderate UV radiation: if a planet receives too little UV flux, many biological compounds cant be synthesized. If it receives too much, however, then terrestrial biological systems (e.g. DNA) can be damaged.To determinethe most likely place to findpersistent life, we should therefore look for the region where a stars traditional habitable zone, within which liquid water is possible, overlaps with its UV habitable zone, within which the UV flux is at the right level to support life.Relationship between the stellar mass and location of the boundaries of the traditional and UV habitable zones for a solar-metallicity star. din and dout denote inner and outer boundaries, respectively.

    2014-01-01

    Determining planetary habitability is a complex matter, as the interplay between a planet's physical and atmospheric properties with stellar insolation has to be studied in a self consistent manner. Standardized atmospheric models for Earth-like planets exist and are commonly accepted as a reference for estimates of Habitable Zones. In order to define Habitable Zone boundaries, circular orbital configurations around main sequence stars are generally assumed. In gravitationally interacting multibody systems, such as double stars, however, planetary orbits are forcibly becoming non circular with time. Especially in binary star systems even relatively small changes in a planet's orbit can have a large impact on habitability. Hence, we argue that a minimum model for calculating Habitable Zones in binary star systems has to include dynamical interactions.

    The application of the vertical hoisting jack and wave motion compensation techniques to the salvage of an ancient sunken boat is introduced. The boat is wooden, loaded with cultural relics. It has been immersed at the bottom of the South China Sea for more than 800 years. In order to protect the structure of the boat and the cultural relics inside to the largest extent, an open caisson is used to hold the sunken boat and the silts around before they are raised from the seabed all together as a whole. In the paper, first, the seakeeping model test of the system of the salvage barge and the open caisson is done to determine some important wave response parameters. And then a further experimental study of the application of the vertical hoisting jack and wave motion compensation scheme to the salvage of the sunken boat is carried out. In the model tests, the techniques of the integrative mechanic-electronic-hydraulic control, wave motion forecast and wave motion compensation are used to minimize the heave motion of the open caisson. The results of the model tests show that the heave motion of the open caisson can be reduced effectively by the use of the present method.

    One approach to commercial fishing is to use use bright lights at night to attract catch. This is a widely used practice in East and Southeast Asia, but can also be found in other fisheries. In some cases, the deployed lighting exceeds 100,000 watts. Such lighting is distinctive in dark ocean and can even be seen from space with sensor such as Visible Infrared Imaging Radiometer Suite Day/Night Band (VIIRS-DNB). We have developed a VIIRS Boat Detection (VBD) system, which outputs lists of boat locations in near real time. One of the standard methods fishery agencies use to collect geospatial data on fishing boats is to require boats to carry Vessel Monitoring System beacons. We developed an algorithm to cross-match VBD data with VMS tracks. With this we are able to identify fishing boats that do not carry VMS beacons. In certain situations, this is an indicator of illegal fishing. The other application for this cross-matching is to define the VIIRS detection limits and developing a calibration to estimate deployed wattage. Here we demonstrate results of cross matching VBD and VMS for Indonesia as example to showcase its potential.

    2017-07-01

    In southern beach of West Java, Indonesia, there are many villagers live as fishermen. They use small boats for fishing, in one to three days. Therefore, they need a fish preservation system. Fortunately, the area has high potential of solar and wind energy. This paper presents the design of a hybrid solar and wind energy harvester to power a refrigerator in the fishing boat. The refrigerator should keep the fish in 2 - 4 °C. The energy needed is 720 Wh daily. In the area, the daily average wind velocity is 4.27 m/s and the sun irradiation is 672 W/m2. The design combined two 100W solar panels and a 300W wind turbine. The testing showed that the solar panels can harvest 815 - 817 Wh of energy, while the wind turbine can harvest 43 - 62 Wh of energy daily. Therefore, the system can fulfil the energy requirement in fishing boat, although the solar panels were more dominant. To install the wind turbine on the fishing-boat, a computational design had been conducted. The boat hydrostatic dimension was measured to determine its stability condition. To reach a stable equilibrium condition, the wind turbine should be installed no more than 1.7 m of height.

    Measurement of sediment deposition and erosion in coastal areas is a challenge due to soft shifting sediments, but is critical to assessing loss or restoration of coastal sediments and wetlands. The aim of this project was to design and construct a semi-autonomous boat with water depth measuring capabilities. It was intended to map the depth of coastal wetlands to determine erosion rates and assess coastal restoration effects. Depth-measuring equipment was incorporated into an autonomous pontoon boat powered by solar panels. The propulsion system consisted of two paddlewheels and two-way motors to allow movement and positioning for measurements. Modifications included a lightweight, hard coating on the pontoons and powder-coating the frame to extend their usable life. A microcontroller controlled the boat and captured depth data from sensors and location data with a GPS system. The depth measuring system consisted of a pulley and counter system that completed each measurement in less than 45 seconds. This allowed the boat to take approximately 400 measurements per day. Net accuracy was approximately 3 cm in the tested configuration. The boat can continually measure the depth of specified areas in the wetlands; with this data, the change in depth can be monitored to see the effects of restoration projects.

    Can healthy food-choice habits protect people against temptations of consuming large portion sizes and unhealthy foods? In two studies, we show that the answer is yes, good habits serve this protective role, at least in contexts in which people are not deliberating and thus fall back on habitual responses. In the first study, participants trained with unhealthy habits to approach eating chocolate, but not those trained with healthy habits, succumbed to temptation and ate more chocolates when their self-control resources were depleted. Study 2 extended and clarified these findings by demonstrating the role of environmental cues in eliciting healthy habits when self-control resources are depleted. Participants who had been trained to choose carrots habitually to a pictorial stimulus (i.e., habit cue) subsequently resisted choosing M&Ms as long as the cue was present. This effect of habit cues on healthy food choices suggests the usefulness of manipulating such cues as a means of meeting self-regulatory goals such as portion control. Copyright © 2015 Elsevier Ltd.

    Compulsivity has been recently characterized as a manifestation of an imbalance between the brain׳s goal-directed and habit-learning systems. Habits are perhaps the most fundamental building block of animal learning, and it is therefore unsurprising that there are multiple ways in which the development and execution of habits can be promoted/discouraged. Delineating these neurocognitive routes may be critical to understanding if and how habits contribute to the many faces of compulsivity observed across a range of psychiatric disorders. In this review, we distinguish the contribution of excessive stimulus-response habit learning from that of deficient goal-directed control over action and response inhibition, and discuss the role of stress and anxiety as likely contributors to the transition from goal-directed action to habit. To this end, behavioural, pharmacological, neurobiological and clinical evidence are synthesised and a hypothesis is formulated to capture how habits fit into a model of compulsivity as a trans-diagnostic psychiatric trait.

    There are tremendous variations in diapering practices, reflecting varying cultural practices and regional difference. Around the world, more than 134 million babies are born each year, a rate of 255 births per minute or 4.3 births each second. While global population growth has been steadily declining from its peak in 1963, several regions, including the Middle East and Sub-Saharan Africa, continue to maintain high birth rates. Though the essential needs of infants are largely similar, family habits and practices during early years of life vary dramatically. This article surveys data documenting variations in diaper frequency, types, and duration of use internationally, including age of toilet training. These factors may influence diaper rash and skin health of infants and young children. Much of this data was collected as part of analysis of the international commercial diaper market, evaluated and organized as part of an international initiative on Global Infant Skin Care, and presented to a panel of experts for critique and commentary in a symposium held in December, 2013. © 2014 Wiley Periodicals, Inc.

It is incorporated with a stable mechanical system with air and water propulsion, robotic arms and solar energy source and it is proceed to become autonomous by using computer vision. Both "HSV Color Space" and "SURF" are proposed to use for measurements in Kalman Filter resulting in extremely robust pollutant tracking. The system has been tested with successful results in the Yamuna River in New Delhi. We foresee that a system of Ro-boats working autonomously 24x7 can clean a major river in a city on about six months time, which is unmatched by alternative methods of river cleaning.

    Kylin, Henrik; Haglund, Kurt

    2010-10-01

    Copper, zinc, and Irgarol 1051 concentrations were determined around a pleasure boat marina in the Stockholm Archipelago. Copper concentrations in water were twice as high (6.62 μg L⁻¹) in 2004 as 1992-1993, zinc concentrations six times higher (20.0 μg L⁻¹). Concentrations in bladder wrack (Fucus vesiculosus) had also risen. Irgarol concentrations in water were similar (~0.17 μg L⁻¹) in 1996 and 2004, while concentrations in bladder wrack halved from 1993 to 2004. The peak concentrations of copper and Irgarol in water have shifted indicating that the main source in the 1990 s were local boats, but in 2004 visiting boats.

In the calculations, the contributions from static and low frequency (LF motions are considered from the hydrodynamic and mooring analysis as well as damage angle from the intact and damage stability analysis. Also, Air-gap calculation at the life boat positions has been carried out to check the effect on the life boat arrangement. The air-gap assessment is based on the extreme air-gap method includes the effect of 1st order wave frequency (WF motions, 2nd order low frequency roll/pitch motion, static trim/heel and set down.

  11. Habitability from a microbial point of view

    We examine here the definition of habitability from the point of view of primitive, anaerobic microorganisms noting that the conditions of habitability are different for the appearance of life, for established life, and for life in dormant mode [1]. Habitability in this sense is clearly distinguished from the 'prebiotic world' that precedes the appearance of life. The differences in the conditions of habitability necessary for life to appear, for life to flourish and for dormant life entrain differences in spatial and temporal scales of habitability. For the origin of life, the ingredients carbon molecules, water, nutrients and energy need to be present on time scales applicable for the origin of life (105 to a few 106 y ?), necessitating the spatial scales of a minimum of ~100 km. Established life can take advantage of short-lived habitats (hours, days) to much longer lived ones on spatial scales of 100s μm to cm-m, whereas dormant life can survive (but not metabolise) in extreme environments for very long periods (perhaps up to millions of years) at microbial spatial scales (100s μm - mms). Thus, it is not necessary for the whole of a planet of satellite to be habitable. But the degree of continued habitability will have a strong influence on the possibility of organisms to evolve. For a planet such as Mars, for instance, microbial habitability was (perhaps still is) at different times and in different places. Habitable conditions conducive to the appearance of life, established life and possibly even dormant life could co-exist at different locations. Reference: [1] F. Westall, D. Loizeau, F. Foucher, N.

  12. The application of genetic fuzzy clustering in bad data identification

    2006-11-01

    Power system static state estimation is aimed at providing modern electric control centers with accurate and reliable real-time databases. To this end, not only should the state estimator be able to filter out random observation noise but it should also be able to detect the existence, identify the locations and remove the effects of bad data. Detecting and identifying bad data is very important in state estimation of power system. A new method presented in this paper is fuzzy clustering with genetic search. And simulation data proves that error contamination and submergence can be reduced so that real bad data can be detected and identified. A key advantage of the proposed method is that the clustering is independent of the space distribution of input samples. This method possesses characteristics so faster convergence rate and more exact clustering results than some typical clustering algorithms.

  13. Stability analysis for bad cavity lasers with inhomogeneously broadened gain

    CERN Document Server

    Kazakov, Georgy A

    2016-01-01

    Bad cavity lasers are experiencing renewed interest in the context of active optical frequency standards, due to their enhanced robustness against fluctuations of the laser cavity. The gain medium would consist of narrow-linewidth atoms, either trapped inside the cavity or intersecting the cavity mode dynamically. A finite velocity distribution, atomic interactions, or interactions of realistic multilevel atoms with external field leads to an inhomogeneous broadening of the atomic gain profile. This can bring the bad cavity laser to operate in unstable regimes characterized by complex temporal patterns of the field amplitude. We present a new and efficient method for the stability analysis of bad cavity lasers with inhomogeneously broadened gain. We apply this method to identify the steady-state solutions for the metrology-relevant case of spin-1/2 atoms interacting with an external magnetic field.

    2014-12-01

    Full Text Available The 2008–09 global crisis raised debates concerning the determinants of financial vulnerability. Among these, bad loans have been identified as significantly influencing financial imbalances. After a decade in which borrowing has constantly grown mainly because of the deregulation of financial markets, the crisis highlighted the importance of an effective credit risk management. The purpose of the paper is to study the evolution of bad loans ratio in relation with selected macroeconomic indicators in the Baltic countries (Estonia, Latvia and Lithuania and Romania.

    2015-01-01

    Current vision systems are designed to perform in normal weather condition. However, no one can escape from severe weather conditions. Bad weather reduces scene contrast and visibility, which results in degradation in the performance of various computer vision algorithms such as object tracking, segmentation and recognition. Thus, current vision systems must include some mechanisms that enable them to perform up to the mark in bad weather conditions such as rain and fog. Rain causes the spatial and temporal intensity variations in images or video frames. These intensity changes are due to the

    1935-01-01

    A 1/5-scale model of a flying-boat hull having flutes in the bottom both forward and aft of the step (NACA model 19) was tested to determine its water performance. The model was also tested after the successive removal of the flutes on the afterbody and forebody. The results from these tests are compared with those from tests of a model of the hull of the Navy PN-8 flying boat and it is concluded that the fluted-bottom model and its modifications are inferior to the model of the PN-8.

  17. THEORETICAL AND EXPERIMENTAL INVESTIGATION OF GAIN SCHEDULING AND ADAPTIVE AUTOPILOTS FOR A MODEL BOAT

    Directory of Open Access Journals (Sweden)

    M. MURALI KRISHNA,

    2011-02-01

    Full Text Available In this paper Gain scheduling PD controller and Adaptive PD controller are adopted as autopilot systems for a boat model. The control design is based on Nomoto’s first order mathematical model. Adaptive controller is based on model reference adaptive controller theory. Similar test runs are conducted on a model boat with the above controller algorithms. The effectiveness of the two controllers are compared numerically and graphically. The results show that both controllers are well for reaching the desired heading angle. The adaptive controller has some notable advantage over gain scheduling controller.

  3. A Volcanic Hydrogen Habitable Zone

    Science.gov (United States)

    Ramirez, Ramses M.; Kaltenegger, Lisa

    2017-03-01

    The classical habitable zone (HZ) is the circular region around a star in which liquid water could exist on the surface of a rocky planet. The outer edge of the traditional N2–CO2–H2O HZ extends out to nearly ∼1.7 au in our solar system, beyond which condensation and scattering by CO2 outstrips its greenhouse capacity. Here, we show that volcanic outgassing of atmospheric H2 can extend the outer edge of the HZ to ∼2.4 au in our solar system. This wider volcanic-hydrogen HZ (N2–CO2–H2O–H2) can be sustained as long as volcanic H2 output offsets its escape from the top of the atmosphere. We use a single-column radiative-convective climate model to compute the HZ limits of this volcanic hydrogen HZ for hydrogen concentrations between 1% and 50%, assuming diffusion-limited atmospheric escape. At a hydrogen concentration of 50%, the effective stellar flux required to support the outer edge decreases by ∼35%–60% for M–A stars. The corresponding orbital distances increase by ∼30%–60%. The inner edge of this HZ only moves out ∼0.1%–4% relative to the classical HZ because H2 warming is reduced in dense H2O atmospheres. The atmospheric scale heights of such volcanic H2 atmospheres near the outer edge of the HZ also increase, facilitating remote detection of atmospheric signatures.

  4. On the Habitability of Our Universe

    Loeb, Abraham

    2016-01-01

    Is life most likely to emerge at the present cosmic time near a star like the Sun? We consider the habitability of the Universe throughout cosmic history, and conservatively restrict our attention to the context of "life as we know it" and the standard cosmological model, LCDM. The habitable cosmic epoch started shortly after the first stars formed, about 30 Myr after the Big Bang, and will end about 10 Tyr from now, when all stars will die. We review the formation history of habitable planets and find that unless habitability around low mass stars is suppressed, life is most likely to exist near 0.1 solar mass stars ten trillion years from now. Spectroscopic searches for biosignatures in the atmospheres of transiting Earth-mass planets around low mass stars will determine whether present-day life is indeed premature or typical from a cosmic perspective.

    Terrestrial planets are more likely to be detected if they orbit M dwarfs due to the favorable planet/star size and mass ratios. However, M dwarf habitable zones are significantly closer to the star than the one around our Sun, which leads to different requirements for planetary habitability and its detection. We review 1) the current limits to detection, 2) the role of M dwarf spectral energy distributions on atmospheric chemistry, 3) tidal effects, stressing that tidal locking is not synonymous with synchronous rotation, 4) the role of atmospheric mass loss and propose that some habitable worlds may be the volatile-rich, evaporated cores of giant planets, and 5) the role of planetary rotation and magnetic field generation, emphasizing that slow rotation does not preclude strong magnetic fields and their shielding of the surface from stellar activity. Finally we present preliminary findings of the NASA Astrobiology Institute's workshop "Revisiting the Habitable Zone." We assess the recently-announced planet ...

  14. Expression of the Bcl-2 protein BAD promotes prostate cancer growth.

    Directory of Open Access Journals (Sweden)

    Adrienne J Smith

    Full Text Available BAD, a pro-apoptotic protein of the Bcl-2 family, has recently been identified as an integrator of several anti-apoptotic signaling pathways in prostate cancer cells. Thus, activation of EGFR, GPCRs or PI3K pathway leads to BAD phosphorylation and inhibition of apoptosis. Increased levels of BAD in prostate carcinomas have also been reported. It appears contradictory that instead of limiting expression of pro-apoptotic protein, prostate cancer cells choose to increase BAD levels while keeping it under tight phosphorylation control. Analysis of the effect of BAD on prostate cancer xenografts has shown that increased BAD expression enhances tumor growth, while knockdown of BAD expression by shRNA inhibits tumor growth. Tissue culture experiments demonstrated that increased BAD expression stimulates proliferation of prostate cancer cells. These results suggest that increased expression of BAD provides a proliferative advantage to prostate tumors, while BAD dephosphorylation increases sensitivity of prostate cancer cells to apoptosis. Combination of proliferative and apoptotic properties prompts prostate cancer cells to be "addicted" to increased levels of phosphorylated BAD. Thus, kinases that phosphorylate BAD are plausible therapeutic targets; while monitoring BAD phosphorylation could be used to predict tumor response to treatments.

  18. Habitable worlds with no signs of life.

    Science.gov (United States)

    Cockell, Charles S

    2014-04-28

    'Most habitable worlds in the cosmos will have no remotely detectable signs of life' is proposed as a biological hypothesis to be tested in the study of exoplanets. Habitable planets could be discovered elsewhere in the Universe, yet there are many hypothetical scenarios whereby the search for life on them could yield negative results. Scenarios for habitable worlds with no remotely detectable signatures of life include: planets that are habitable, but have no biosphere (Uninhabited Habitable Worlds); planets with life, but lacking any detectable surface signatures of that life (laboratory examples are provided); and planets with life, where the concentrations of atmospheric gases produced or removed by biota are impossible to disentangle from abiotic processes because of the lack of detailed knowledge of planetary conditions (the 'problem of exoplanet thermodynamic uncertainty'). A rejection of the hypothesis would require that the origin of life usually occurs on habitable planets, that spectrally detectable pigments and/or metabolisms that produce unequivocal biosignature gases (e.g. oxygenic photosynthesis) usually evolve and that the organisms that harbour them usually achieve a sufficient biomass to produce biosignatures detectable to alien astronomers.

    Full Text Available Introduction: Eating habits are formed in childhood and adolescence.. Economic issues including social and demographic factors influence the choice and quality of products consumed. Aim: The aim of the study is to determine the impact of socio-economic status (SES on eating habits of students in lower secondary schools. Material and methods: At the turn of 2011 and 2012, an epidemiological cross-sectional study on 1,099 students in lower secondary schools from Bytom was conducted. The questionnaire was based on the form used in Health Behaviour in School – aged Children study (HBSC. The socio-economic status of students was determined according to the Family Affluence Scale (FAS and the mother’s level of education. The statistical analysis was conducted using Statistica 10.0 software. The significance level was set at p40.05. Results: 1,099 students in lower secondary school took part in the study (55.6% females and 44.4% males. 59% of students skip vegetables in their daily diet, (58.5% fruits and (49.4%. milk but 59.7% have breakfast every day. Nevertheless the high percentage of children eating sweets every day or several times a day (37.2% is worrying. Those children whose mothers declared secondary education and high level of FAS have proper eating habits. Children eating sweets at least once a day come mostly from families with low level of FAS. Conclusions: Bad eating habits are mostly among children whose mothers are of primary or vocational education and a low level of FAS.

    Full Text Available The sleep disorders are among the most common behaviour problems in infancy and early childhood, not only affect children, but parents also suffer from lack of sleep which creates problems of anxiety and communication in the partner by exhaustion. One way to prevent insomnia in children is that parents know how to create the habit of sleeping with their children.The main aims of the protocol are: - To train parents to establish healthy habits for proper sleep hygiene.- Preventing sleep disorders caused by bad habits in the infant. - To prevent symptoms of anxiety due to lack of sleep in the parents.The program will consist of 6 sessions of 90 minutes long, 3 pre-natal where they thrive knowledge and 3 sessions after to exposure doubts and search for solutions. We think that cooperation between the mental health nurse specialist with the midwife it is necessary to create a program that establish a healthy dream pattern in both infants and their parents, will prevent the sleep disorders by incorrect habits and their effects

    2007-07-01

    This study describes the communication style preferences of Japanese patients when receiving bad news, examines the factor structure of the measure for patients' preferences (MPP) in a Japanese population, and explores variables that may be associated with patients' communication style preferences. Five hundred twenty-nine cancer outpatients completed several psychosocial measures including the Japanese version of the MPP (MPP-J), the Mental Adjustment to Cancer Scale (MAC), and the Hospital Anxiety and Depression Scale (HADS). The patients desired detailed information and a supportive environment when receiving bad news. The MPP-J demonstrated a 5-factor structure: support, facilitation, medical information, clear explanation, and encouraging question-asking. Regression analyses indicated that a female gender, the fighting spirit and anxious preoccupation dimensions of the MAC were positively associated with all 5 MPP-J factors. In conclusion, Japanese cancer patients' preferences for communication when receiving bad news differ somewhat from those of American patients. Japanese physicians should encourage patients to ask questions and should consider the demographic (e.g. gender), medical (disease status) and psychosocial characteristics (fighting spirit and anxious preoccupation) of patients when delivering bad news.

  17. Aliens in Paradise. Boat density and exotic coastal mollusks in Moorea Island (French Polynesia).

    Pacific islands are particularly vulnerable to the effects of invasive species. After habitat destruction or modification, invasive species are responsible for more biological extinctions than any other cause. Further, the rate of extinction of native species has been higher on islands than anywhere else in the world. Invasive species have also degraded native ecosystems. In order to detect exotic intertidal mollusk species, an extensive sampling around Moorea Island, a more or less unspoiled island surrounded by a rich coral reef habitat, has been developed considering that sampled points have different characteristics in wave exposure, algae coverage, type of substrate, distance to ports, distance to freshwater, distance sewage and boat traffic. Samples were DNA barcoded for unequivocal species assignation. The presence of five NIS among 26 species seems an important signal of introduction of alien biota in Moorea Island coast. However they were represented by a total of 38 individuals among 1487 mollusks (2.55%). While the distance to relatively big ports influenced directly species richness, the intensity of maritime traffic measured as boat density near sampling points was significantly associated with the frequency of exotic species. Other environmental factors did not show significant correlation with the frequency of exotics, suggesting that in an environment without big discontinuities, with little habitat modification, local boat traffic is the most influential factor in the spread of exotic species. This could be mitigated relatively easily by reducing boat density in local zones of ecological interest. Copyright © 2015 Elsevier Ltd. All rights reserved.

  1. BOAT: automatic alignment of biomedical ontologies using term informativeness and candidate selection.

    Science.gov (United States)

    Chua, Watson Wei Khong; Kim, Jung-Jae

    2012-04-01

    The biomedical sciences is one of the few domains where ontologies are widely being developed to facilitate information retrieval and knowledge sharing, but there still remains the problem that applications using different ontologies cannot share knowledge without explicit references between overlapping concepts. Ontology alignment is the task of identifying such equivalence relations between concepts across ontologies. Its application to the biomedical domain should address two open issues: (1) determining the equivalence of concept-pairs which have overlapping terms in their names, and (2) the high run-time required to align large ontologies which are typical in the biomedical domain. To address them, we present a novel approach, named the Biomedical Ontologies Alignment Technique (BOAT), which is state-of-the-art in terms of F-measure, precision and speed. A key feature of BOAT is that it considers the informativeness of each component word in the concept labels, which has significant impact on biomedical ontologies, resulting in a 12.2% increase in F-measure. Another important feature of BOAT is that it selects for comparison only concept pairs that show high likelihoods of equivalence, based on the similarity of their annotations. BOAT's F-measure of 0.88 for the alignment of the mouse and human anatomy ontologies is on par with that of another state-of-the-art matcher, AgreementMaker, while taking a shorter time.

    2013-01-01

    Using the renowned leisure boat-building sector in the Marche Region (Italy) as a case-study, this paper addresses the characterization of (1) the industrial waste generation from the building of composite material-based boats and (2) some chemical-physical properties of representative types of boat-building residues (plastic foam, hardened resin, fibre-reinforced composite residues, and sanding dust). A parametric evaluation based on the number of employees gave a representative unit generation rate per employee (UGRpE) of 1.47 tons(waste) employee(-1) year(-1) for the entire Marche regional boatbuilding district, whereas evaluations carried out separately for three case-study companies provided values of 1.56, 3.07, and 1.12 tons(waste) employee(-1) year(-1) as representative for a mass-produced motor boat builder (case-study company '1'), a customized sailing boat builder (case-study company '2'), and a mould and structural component builder (case-study company '3'), respectively. The original proposal and evaluation of two additional generation rates based on physical characteristics intrinsic to the manufactured product, i.e. the unit generation rate per boat area (UGRpA) and per boat weight (UGRpW), confirmed the higher waste generation for the sailing boat builder(representative UGRpA and UGRpW values of 0.35 tons(waste) m(-2)(boat) year(-1) and 2. 71 tons(waste) tons(-1)(boat) year(-1), respectively) compared with the motor boat builder (representative UGRpA and UGRpW values of 0.06 tons(waste) m(-2)(boat) year(-1) and 0.49 tons(waste) tons(-1)(boat) year(-1), respectively). The chemical-physical property characterization of the selected residues revealed the following aspects: a general condition of low moisture contents; significant ash contents in the glass- and carbon-fibre composite residues and the correlated sanding dust; and relatively high energy content values in the overall range 14,144-32,479 kJ kg(-1), expressed as the lower heating value.

    Full Text Available Introduction: Discussion of bad news and resuscitation in terminal cancer is an important but difficult and often neglected issue in day-to-day oncology practice. Materials and Methods: We interviewed 35 radiation oncologists using an indigenous 15-item questionnaire on their beliefs about breaking bad news and resuscitation to terminal cancer patients. Results: Most responders had an oncology experience of three to seven years (20/35.Thirty-two were comfortable discussing cancer diagnosis, prognosis and life expectancy-related issues. A similar number believed all cancer-related information should be disclosed, while only four believed in imparting all information in one visit. All agreed that disclosing sensitive information did not affect survival. When requested by relatives to withhold truth from patients, 11 said they would not comply, 22 agreed to tell the truth only if asked and two agreed to avoid difficult questions. Twenty responders denied having been adequately trained in breaking bad news and were keen on dedicated classes or sessions in this area of practice. Most (33/35 believed that Indian patients were keen on knowing their diagnosis and prognosis. Although all agreed to the importance of discussing resuscitation, only 17 believed patients should be involved. Majority (20/35 agreed that the issue needs to be discussed while the patient was conscious. Patients with unsalvageable disease were deemed unsuitable for aggressive resuscitation by 30 responders while the rest believed it should be offered to all. Most (21/35 admitted to feeling depressed after breaking bad news though only seven felt disclosure was more stressful than untruthful statements. Only four knew of a law regarding resuscitation in cancer. Conclusion: Observing the widely varied beliefs and practices for disclosing bad news, it is recommended that such training be a regular part of medicine curriculum, especially in the Oncology setting.

  12. Application of Laminated Veneer Lumber (LVL on the Wooden Boat Construction

    Directory of Open Access Journals (Sweden)

    Ahmad Basuki Widodo

    2012-02-01

    Full Text Available LVL (Laminated-Veneer Lumber has many advantages and economic values, which is important for wooden boat construction. The recovery of veneer, the main material of LVL, are higher than sawn-timber and their drying process are faster. LVL produced with a continuous press has been approved as an engineered material with reliable strength and stiffness. In a wooden boat processing, the easy forming into a curve shape and strength are main factor, because of the streamline shape of boats. LVL material is able to meet those requirements. As an endless-length LVL is made from a log limited-length hence LVL always contain joints. Butt joint have numerous drawbacks, but they are inherently simple and less time to manufacture than other joints types. The purposes of this experiment are to investigate the basic characteristics of LVL which are important for deck and hull planking in the wooden boat constructions. Yellow meranti and red meranti were peeled by a veneer lathe and phenol formaldehyde adhesive were used. Result of experiment indicated that at the position 0o (β, the flexibility and strength of LVL up to proportional limit increased with increasing number of layer and spacing of butt-joint (d/t. LVL at the position 45o and 90o (β, all types of LVL had lower flexibility and strength than the standard value for deck and hull planking. In bending experiment test speciment at position 45° with direction of grain, maximum width of LVL equal to the spacing of frame and at position 90° equal to the width of hull planking in wooden boat. Based on the interpretations of the above results, it can be concluded that (1. LVL of 9, 6 and 4 plies with upside (inside veneer butt-joint is appropriate for deck and hull planking in wooden boat manufacturing, (2. LVL of 9, 6 and 4 plies with spacing of butt-joint (d/t more than 20 is appropriate for deck and hull planking in manufacturing wooden boat.

  19. Evaluation of ADCP apparent bed load velocity in a large sand-bed river: Moving versus stationary boat conditions

    Jamieson, E.C.; Rennie, C.D.; Jacobson, R.B.; Townsend, R.D.

    2011-01-01

    Detailed mapping of bathymetry and apparent bed load velocity using a boat-mounted acoustic Doppler current profiler (ADCP) was carried out along a 388-m section of the lower Missouri River near Columbia, Missouri. Sampling transects (moving boat) were completed at 5- and 20-m spacing along the study section. Stationary (fixed-boat) measurements were made by maintaining constant boat position over a target point where the position of the boat did not deviate more than 3 m in any direction. For each transect and stationary measurement, apparent bed load velocity (vb) was estimated using ADCP bottom tracking data and high precision real-time kinematic (RTK) global positioning system (GPS). The principal objectives of this research are to (1) determine whether boat motion introduces a bias in apparent bed load velocity measurements; and (2) evaluate the reliability of ADCP bed velocity measurements for a range of sediment transport environments. Results indicate that both high transport (vb>0.6 m/s) and moving-boat conditions (for both high and low transport environments) increase the relative variability in estimates of mean bed velocity. Despite this, the spatially dense single-transect measurements were capable of producing detailed bed velocity maps that correspond closely with the expected pattern of sediment transport over large dunes. ?? 2011 American Society of Civil Engineers.

  2. Habitable Climates: The Influence of Eccentricity

    CERN Document Server

    Dressing, Courtney D; Scharf, Caleb A; Raymond, Sean N

    2010-01-01

    Radiative equilibrium studies that place Earth-like exoplanets on different circular orbits from the parent star do not fully sample the range of plausible habitability conditions in planetary systems. In the outer regions of the habitable zone, the risk of transitioning into a globally frozen "snowball" state poses a threat to the habitability. Here, we use a one-dimensional energy balance climate model (EBM) to examine how obliquity, spin rate, orbital eccentricity, and the fraction of the surface covered by ocean might influence the onset of such a snowball state. Since, for constant semimajor axis, the annual mean stellar irradiation scales with (1-e^2)^(-1/2), one might expect the greatest habitable semimajor axis to scale as (1-e^2)^(-1/4). We find that this standard simple ansatz provides a reasonable lower bound on the outer boundary of the habitable zone, but the influence of both obliquity and ocean fraction can be profound in the context of planets on eccentric orbits. For planets with eccentricity...

    We have previously demonstrated that the anti-apoptotic protein BAD is expressed in normal human breast tissue and shown that BAD inhibits expression of cyclin D1 to delay cell-cycle progression in breast cancer cells. Herein, expression of proteins in breast tissues was studied by immunohistochemistry and results were analyzed statistically to obtain semi-quantitative data. Biochemical and functional changes in BAD-overexpressing MCF7 breast cancer cells were evaluated using PCR, reporter assays, western blotting, ELISA and extracellular matrix invasion assays. Compared to normal tissues, Grade II breast cancers expressed low total/phosphorylated forms of BAD in both cytoplasmic and nuclear compartments. BAD overexpression decreased the expression of β-catenin, Sp1, and phosphorylation of STATs. BAD inhibited Ras/MEK/ERK and JNK signaling pathways, without affecting the p38 signaling pathway. Expression of the metastasis-related proteins, MMP10, VEGF, SNAIL, CXCR4, E-cadherin and TlMP2 was regulated by BAD with concomitant inhibition of extracellular matrix invasion. Inhibition of BAD by siRNA increased invasion and Akt/p-Akt levels. Clinical data and the results herein suggest that in addition to the effect on apoptosis, BAD conveys anti-metastatic effects and is a valuable prognostic marker in breast cancer. - Highlights: • BAD and p-BAD expressions are decreased in breast cancer compared with normal breast tissue. • BAD impedes breast cancer invasion and migration. • BAD inhibits the EMT and transcription factors that promote cancer cell migration. • Invasion and migration functions of BAD are distinct from the BAD's role in apoptosis.

    We discuss how to read a planet's spectrum to assess its habitability and search for the signatures of a biosphere. After a decade rich in giant exoplanet detections, observation techniques have advanced to a level where we now have the capability to find planets of less than 10 Earth masses (M(Earth)) (so-called "super Earths"), which may be habitable. How can we characterize those planets and assess whether they are habitable? This new field of exoplanet search has shown an extraordinary capacity to combine research in astrophysics, chemistry, biology, and geophysics into a new and exciting interdisciplinary approach to understanding our place in the Universe. The results of a first-generation mission will most likely generate an amazing scope of diverse planets that will set planet formation, evolution, and our planet into an overall context.

    The evolution of Earth-like habitable planets is a complex process that depends on the geodynamical and geophysical environments. In particular, it is necessary that plate tectonics remain active over billions of years. These geophysically active environments are strongly coupled to a planet's host star parameters, such as mass, luminosity and activity, orbit location of the habitable zone, and the planet's initial water inventory. Depending on the host star's radiation and particle flux evolution, the composition in the thermosphere, and the availability of an active magnetic dynamo, the atmospheres of Earth-like planets within their habitable zones are differently affected due to thermal and nonthermal escape processes. For some planets, strong atmospheric escape could even effect the stability of the atmosphere.

  7. Environmental Signatures for Habitability: What to Measure and How to Rank the Habitability Potential of Mars

    The environmental signatures for habitability are not necessarily biosignatures, even though on Earth, they are definitive proof of habitability. It is the constant overprint of the chemical signatures of life that makes it difficult to recognize the chemical and physical properties of a potentially habitable environment as distinct from an inhabited one. Mars Science Laboratory (MSL) will soon embark on a mission to Mars to assess its past or present habitability, so it is useful to examine how we measure habitability on Earth and prepare for how that approach may differ for Mars. This exercise includes: (a) articulation of fundamental assumptions about habitability, (b) an inventory of factors that affect habitability, (c) development of metrics, measurement approach and implementation, and (d) a new classification scheme for planetary habitability that goes beyond the binary "yes" or "no." There may be dozens of factors that affect habitability and they can be weighted as a function of specific environment. However a robotic, in situ investigation even on Earth has constraints that prevent the measurement of every environmental factor, so metrics must be reduced to the most relevant subset, given available time, cost, technical feasibility and scientific importance. Many of the factors could be measured with a combination of orbital data and the MSL payload. We propose that, at a minimum, a designation of high habitability potential requires the following conditions be met: (a) thermally stable with respect to extremes and frequency of fluctuation, (b) has more than one energy source, (c) sufficient chemical diversity to make compounds with covalent and hydrogen bonding, (d) can moderate ionizing radiation enough to allow a stable or evolving pool of organic molecules, (e) must have water or other high quality polar solvent, (f) must be able to renew chemical resources (e.g., plate tectonics, volcanism or something else we haven't envisioned).

    Proapoptotic BH-3-only protein Bad (Bcl-Xl/Bcl-2-associated death promoter homolog, Bad) initiates apoptosis in human cells, and contributes to tumorigenesis and chemotherapy resistant in malignancies. This study explored association between the Bad expression level and prognosis in patients with non-small cell lung cancer (NSCLC). In our study, a cohort of 88 resected primary NSCLC cases were collected and analyzed. Bad expression level was determined via immunohistochemical staining assay. The prognostic significances of Bad expression were evaluated with univariate and multivariate survival analysis. The results showed that compared with normal lung tissues, Bad expression level significantly decreased in NSCLC (P Bad expression was associated with adjuvant therapy status. Loss of Bad independently predicted poor prognosis in whole NSCLC cohort and early stage subjects (T1 + T2 and N0 + N1) (all P Bad negative phenotype in NSCLC patients with smoking history, especially lung squamous cell carcinoma (all P Bad is an independent and powerful predictor of adverse prognosis in NSCLC.

    The crystal habit of stishovite changes with the temperature of crystallization at a pressure of about 120 kb. Below 600 degrees C it is bipyramidal; between 600 degrees and 900 degrees C it is granular; and above 900 degrees C it is acicular. This temperature dependence of the crystal habit of stishovite may constitute a highpressure geological thermometer which could indicate limiting values for the peak temperatures that prevailed at craters of meteoritic origin in highly siliceous rocks. It suggests that natural acicular stishovite from the rim sandstone at Meteor Crater, Arizona, crystallized at temperatures above 900 degrees C.

  11. Are Empathy and Compassion Bad for the Professional Social Worker?

    Directory of Open Access Journals (Sweden)

    Peter Nilsson

    2014-11-01

    Full Text Available Recent studies have shown that social workers and other professional helpers who work with traumatized individuals run a risk of developing compassion fatigue or secondary traumatic stress. Some researchers have hypothesized that helpers do this as a result of feeling too much empathy or too much compassion for their clients, thereby implying that empathy and compassion may be bad for the professional social worker. This paper investigates these hypotheses. Based on a review of current research about empathy and compassion it is argued that these states are not the causes of compassion fatigue. Hence, it is argued that empathy and compassion are not bad for the professional social worker in the sense that too much of one or the other will lead to compassion fatigue.

  17. In Praise of Bad Codes for Multi-Terminal Communications

    CERN Document Server

    Bennatan, Amir; Calderbank, A Robert

    2010-01-01

    We examine the Gaussian interference channel and the erasure relay channel. We focus on codes that are non-capacity-achieving ("bad") over appropriate point-to-point (two-terminal) channels. Over Gaussian point-to-point channels, for example, such codes require greater SNR than "good" ones to achieve reliable communications, but often exhibit lower estimation errors whenever the SNR is below the Shannon limit. Over multi-terminal channels, this advantage of "bad" codes at lower SNRs can be exploited by strategies that apply estimation, at various network nodes, to achieve partial decoding. Such strategies include soft partial interference cancelation (soft-IC) and soft decode-and-forward (soft-DF). We develop variants of these two approaches, which are susceptible to rigorous analysis. We focus on applications of "bad" LDPC codes. We develop analysis tools for soft-DF, including simultaneous density evolution (sim-DE), and use standard density evolution to analyze soft-IC. We apply our analysis to the design ...

  18. Biochemical and biophysical investigations of the interaction between human glucokinase and pro-apoptotic BAD.

    Rexford, Alix; Zorio, Diego A R; Miller, Brian G

    2017-01-01

    The glycolytic enzyme glucokinase (GCK) and the pro-apoptotic protein BAD reportedly reside within a five-membered complex that localizes to the mitochondria of mammalian hepatocytes and pancreatic β-cells. Photochemical crosslinking studies using a synthetic analog of BAD's BH3 domain and in vitro transcription/translation experiments support a direct interaction between BAD and GCK. To investigate the biochemical and biophysical consequences of the BAD:GCK interaction, we developed a method for the production of recombinant human BAD. Consistent with published reports, recombinant BAD displays high affinity for Bcl-xL (KD = 7 nM), and phosphorylation of BAD at S118, within the BH3 domain, abolishes this interaction. Unexpectedly, we do not detect association of recombinant, full-length BAD with recombinant human pancreatic GCK over a range of protein concentrations using various biochemical methods including size-exclusion chromatography, chemical cross-linking, analytical ultracentrifugation, and isothermal titration calorimetry. Furthermore, fluorescence polarization assays and isothermal titration calorimetry detect no direct interaction between GCK and BAD BH3 peptides. Kinetic characterization of GCK in the presence of high concentrations of recombinant BAD show modest (BAD BH3 peptides. These results raise questions as to the mechanism of action of stapled peptide analogs modeled after the BAD BH3 domain, which reportedly enhance the Vmax value of GCK and stimulate insulin release in BAD-deficient islets. Based on our results, we postulate that the BAD:GCK interaction, and any resultant regulatory effect(s) upon GCK activity, requires the participation of additional members of the mitochondrial complex.

    This study explored psychosocial experiences of breast cancer survivors involved in dragon boat programs. Twenty women (M(age) = 58.69, SD = 6.85) were interviewed for 45-60 min about their experiences as members of survivor dragon boat teams. Interviews were analyzed using constructivist grounded theory methods. The dragon boat program facilitated social support from women with common challenges and a shared understanding of survivorship. It also provided opportunities to (re)gain a sense of personal control, develop new identities as athletes, and overcome physical challenges. Together these elements contributed to positive psychological growth and linked to the literature on posttraumatic growth. Future physical activity interventions targeting breast cancer survivors may benefit from developing strategies that share key characteristics of dragon boating.

  8. Pigeons can discriminate "good" and "bad" paintings by children.

    Watanabe, Shigeru

    2010-01-01

    Humans have the unique ability to create art, but non-human animals may be able to discriminate "good" art from "bad" art. In this study, I investigated whether pigeons could be trained to discriminate between paintings that had been judged by humans as either "bad" or "good". To do this, adult human observers first classified several children's paintings as either "good" (beautiful) or "bad" (ugly). Using operant conditioning procedures, pigeons were then reinforced for pecking at "good" paintings. After the pigeons learned the discrimination task, they were presented with novel pictures of both "good" and "bad" children's paintings to test whether they had successfully learned to discriminate between these two stimulus categories. The results showed that pigeons could discriminate novel "good" and "bad" paintings. Then, to determine which cues the subjects used for the discrimination, I conducted tests of the stimuli when the paintings were of reduced size or grayscale. In addition, I tested their ability to discriminate when the painting stimuli were mosaic and partial occluded. The pigeons maintained discrimination performance when the paintings were reduced in size. However, discrimination performance decreased when stimuli were presented as grayscale images or when a mosaic effect was applied to the original stimuli in order to disrupt spatial frequency. Thus, the pigeons used both color and pattern cues for their discrimination. The partial occlusion did not disrupt the discriminative behavior suggesting that the pigeons did not attend to particular parts, namely upper, lower, left or right half, of the paintings. These results suggest that the pigeons are capable of learning the concept of a stimulus class that humans name "good" pictures. The second experiment showed that pigeons learned to discriminate watercolor paintings from pastel paintings. The subjects showed generalization to novel paintings. Then, as the first experiment, size reduction test

    Radial velocity surveys are now able to detect terrestrial planets at habitable distance from M-type stars. Recently, two planets with minimum masses below 10 Earth masses were reported in a triple system around the M-type star Gliese 581. Using results from atmospheric models and constraints from the evolution of Venus and Mars, we assess the habitability of planets Gl 581c and Gl 581d and we discuss the uncertainties affecting the habitable zone (HZ) boundaries determination. We provide simplified formulae to estimate the HZ limits that may be used to evaluate the astrobiological potential of terrestrial exoplanets that will hopefully be discovered in the near future. Planets Gl 581c and 'd' are near, but outside, what can be considered as the conservative HZ. Planet 'c' receives 30% more energy from its star than Venus from the Sun, with an increased radiative forcing caused by the spectral energy distribution of Gl 581. Its habitability cannot however be positively ruled out by theoretical models due to u...

    Smoking is still now the main avoidable cause of disease, disability and mortality in industrialized countries. This habit is still very common in workplaces, where anti-smoke efforts seem to be less incisive than among general populations. The study analyzed the diffusion of smoke habit in 8111 male workers in Campania region, employed in different work activities (white collars, blue collars, drivers, cleaning civil servants, porters), so as to evaluate work related features, affecting its assumption and maintenance. Among all workers, smokers prevalence (42.7%) was higher than national male population. Percentages of smokers were highest among drivers (60.7%) and civil servants (52.5%), slightly lower among industry workers (47.3%) and lower among white collars (36.4%). The highest prevalence were found in 41-50 years age group (46.8%), but only among white collars aging was associated with higher smokers prevalence. Lower education degrees and two working variables, shifts and handwork, have been related with significantly smoking habit assumption. Results emphasized that health promotional programs are necessary to reduce smoke habit among workers, particularly among professionally and culturally unqualified subgroups.

  17. On the radius of habitable planets

    CERN Document Server

    Alibert, Yann

    2013-01-01

    The conditions that a planet must fulfill to be habitable are not precisely known. However, it is comparatively easier to define conditions under which a planet is very likely not habitable. Finding such conditions is important as it can help select, in an ensemble of potentially observable planets, which ones should be observed in greater detail for characterization studies. Assuming, as in the Earth, that the presence of a C-cycle is a necessary condition for long-term habitability, we derive, as a function of the planetary mass, a radius above which a planet is likely not habitable. We compute the maximum radius a planet can have to fulfill two constraints: surface conditions compatible with the existence of liquid water, and no ice layer at the bottom of a putative global ocean. We demonstrate that, above a given radius, these two constraints cannot be met. We compute internal structure models of planets, using a five-layer model (core, inner mantle, outer mantle, ocean, and atmosphere), for different mas...

  19. Stability of habitable exomoons of circumbinary planets

    Satyal, Suman; Haghighipour, Nader; Quarles, Billy

    2015-12-01

    Among the currently known Kepler circumbinary planets, three, namely Kepler-453b, Kepler-16b, and Kepler-47c are in the binary habitable zone (HZ). Given the large sizes of these planets, it is unlikely that they would be habitable. However, similar to the giant planets in our solar system, these planets may have large moons, which orbit their host planets while in the HZ. These exomoons, if exist, present viable candidates for habitability. As a condition for habitability, the planet-moon system has to maintain its orbital stability for long time. Usually, the empirical formula by Holeman & Wiegert (1999) is used as a measure of orbital stability in circumbinary systems. However, this formula was obtained by assuming planets to be test particles and therefore does not include possible perturbation of the planet on the binary. In this work, we present results of more realistic calculations of stability of circumbinary planets where the interactions between planets and their central binaries are taken into account. We map the region of stability, which in this case will be specific to each system, and determine the range of the orbital parameters of the moons for which their orbits will be long-term stable.

    Full Text Available Effective reading is essential for success in acquiring a foreign language (Mikulecky 2008. Students have to read a wide range of textbooks and related materials at the tertiary level. Lack of adequate reading habit is, therefore, bound to impede students’ progress towards mastery of a foreign language. This study investigated reading habits and attitudes on reading of the undergraduate students attending ESL courses at a public university in Malaysia. For data collection, a 35 item questionnaire based on the Adult Survey of Reading Attitude (ASRA from the work of Smith (1991 were designed and administered on around 314 students. The questionnaire investigated the students’ general habit, preferences, and attitude towards reading. This study was based on the following research questions: What are the reading habits of these undergraduate students? What are the attitudes of these students to reading as a useful language learning skill? What are the reading preferences of these undergraduate students? The research findings through qualitative analysis revealed that the undergraduate students had an overall positive attitude towards reading in spite of their minimal enjoyment of it and the resulting anxieties and difficulties they face. Based on the findings, few recommendations were made to improve reading among those undergraduates.

  2. Tidal obliquity evolution of potentially habitable planets

    CERN Document Server

    Heller, René; Barnes, Rory

    2011-01-01

    Stellar insolation has been used as the main constraint on a planet's habitability. However, as more Earth-like planets are discovered around low-mass stars (LMSs), a re-examination of the role of tides on the habitability of exoplanets has begun. Those studies have yet to consider the misalignment between a planet's rotational axis and the orbital plane normal, i.e. the planetary obliquity. We apply two equilibrium tide theories to compute the obliquity evolution of terrestrial planets orbiting in the habitable zones around LMSs. The time for the obliquity to decrease from an Earth-like obliquity of 23.5 deg to 5 deg, the 'tilt erosion time', is compared to the traditional insolation habitable zone (IHZ) as a function of semi-major axis, eccentricity, and stellar mass. We also compute tidal heating and equilibrium rotation caused by obliquity tides. The Super-Earth Gl581d and the planet candidate Gl581g are studied as examples for tidal processes. Earth-like obliquities of terrestrial planets in the IHZ arou...

    2012-12-01

    Full Text Available The stern boat deployment system was investigated to evaluate the capability of launching and recovering rigid hull inflatable boat (RHIB via the stern ramp. The main parameters to launch and recover RHIB were tested at the design stage. The combined hydrodynamic effect of the stern wake and the water jet flow made it difficult to maintain the maneuvering and sea-keeping ability of RHIB approaching to the stern ramp. The safe recovery course was proposed to maintain the directional control of RHIB and to reduce the combined hydrodynamic effect in the transom zone. To evaluate the feasibility of RHIB recovery, the stern sill depth was measured in various conditions and the ramp availability time was obtained. Also, the experimental percent time operability (PTO test was performed by the number of successive launching and recovering operations.

In order to compare the effect of bow spray strips and Ω-type freeboards on a high-speed boat, hull wetness, resistance, hull motion, stability and the restoring moment of the heel at high speed of models with these two kinds of auxiliaries were calculated and measured. CFD methods and model tests were adopted. Both of these two auxiliaries can reduce hull wetness, and the model with a Ω-type freeboard has a better initial stability and larger restoring moment of the heel at high speed. A free running model test also indicates that the Ω-type freeboard has a fine performance.

    This paper presents a model for quantifying the random errors (i.e., variance) of acoustic Doppler current profiler (ADCP) discharge measurements from moving boats for different sampling times. The model focuses on the random processes in the sampled flow field and has been developed using statistical methods currently available for uncertainty analysis of velocity time series. Analysis of field data collected using ADCP from moving boats from three natural rivers of varying sizes and flow conditions shows that, even though the estimate of the integral time scale of the actual turbulent flow field is larger than the sampling interval, the integral time scale of the sampled flow field is on the order of the sampling interval. Thus, an equation for computing the variance error in discharge measurements associated with different sampling times, assuming uncorrelated flow fields is appropriate. The approach is used to help define optimal sampling strategies by choosing the exposure time required for ADCPs to accurately measure flow discharge.

    Full Text Available There are lot of research done to develop a patrol boat, from the modification of hull model until propulsion system equipment. For example the model ship type AMV (Advanced Marine Vehicle was developed starting from the Catamaran, Trimaran and  Pentamaran model. Everything is aimed at obtaining the ship design that has the speed and stability. In addition to achieving high-speed vessel must be equipped with propulsion (Main Power is great, that means the main engine dimensions, auxiliary equipments and fuel tanks is too large. Many Limitations of space on the ship's engine room trimaran vessel is the main obstacle in designing propulsion system. Beside that Patrol boat should have many missions speed, so propulsion system should be designed at that conditions.   Hybrid propulsion is a combination of Diesel Mechanical Propulsion (DMP with Diesel Electric Propulsion (DEP. DMP system is connected directly to the propeller shaft (or through a reduction-gear. DMP has provide more efficiency rate of 95%. While DEP is only able to provide efficiency by 85% - 89% is slightly lower than DMP, but the DEP offers many advantages such as simplicity and suitability in the rotational speed settings, control systems, engine power production Redundancy, Flexibility in the design of equipments layout in engine rooms, noise, vibration and fuel consumption efficiency which affects the lower pollution.   Design of Hybrid Propulsion system can be satisfied and achieved the Power requirements and optimally at all speed condition of patrol boat. Therefore the author made using modeling Maxsurf-11.12 software and carried out various optimization of the choice of main engine, propeller and system conditions for fast patrol boat cruise.

    Most discussion of habitable planets has focused on Earth-like planets with globally abundant liquid water. For an "aqua planet" like Earth, the surface freezes if far from its sun, and the water vapor greenhouse effect runs away if too close. Here we show that "land planets" (desert worlds with limited surface water) have wider habitable zones than aqua planets. For planets at the inner edge of the habitable zone, a land planet has two advantages over an aqua planet: (i) the tropics can emit longwave radiation at rates above the traditional runaway limit because the air is unsaturated and (ii) the dry air creates a dry stratosphere that limits hydrogen escape. At the outer limits of the habitable zone, the land planet better resists global freezing because there is less water for clouds, snow, and ice. Here we describe a series of numerical experiments using a simple three-dimensional global climate model for Earth-sized planets. Other things (CO(2), rotation rate, surface pressure) unchanged, we found that liquid water remains stable at the poles of a low-obliquity land planet until net insolation exceeds 415 W/m(2) (170% that of modern Earth), compared to 330 W/m(2) (135%) for the aqua planet. At the outer limits, we found that a low-obliquity land planet freezes at 77%, while the aqua planet freezes at 90%. High-obliquity land and aqua planets freeze at 58% and 72%, respectively, with the poles offering the last refuge. We show that it is possible that, as the Sun brightens, an aqua planet like Earth can lose most of its hydrogen and become a land planet without first passing through a sterilizing runaway greenhouse. It is possible that Venus was a habitable land planet as recently as 1 billion years ago.

    Boat lubricants are continuously released into the marine environment and thereby cause chronic oil pollution. This study aims to isolate lubricant-degrading microorganisms from Thai coastal areas as well as to apply a selected strain for removal of boat lubricants. Ten microorganisms in the genera of Gordonia, Microbacterium, Acinetobacter, Pseudomonas, Brucella, Enterococcus and Candida were initially isolated by crude oil enrichment culture techniques. The lubricant-removal activity of these isolates was investigated with mineral-based lubricants that had been manufactured for the 4-stroke diesel engines of fishing boats. Gordonia sp. JC11, the most effective strain was able to degrade 25-55% of 1,000 mg L(-1) total hydrocarbons in six tested lubricants, while only 0-15% of the lubricants was abiotically removed. The bacterium had many characteristics that promoted lubricant degradation such as hydrocarbon utilization ability, emulsification activity and cell surface hydrophobicity. For bioaugmentation treatment of lubricant contaminated seawater, the inoculum of Gordonia sp. JC11 was prepared by immobilizing the bacterium on polyurethane foam (PUF). PUF-immobilized Gordonia sp. JC11 was able to remove 42-56% of 100-1,000 mg L(-1) waste lubricant No. 2 within 5 days. This lubricant removal efficiency was higher than those of free cells and PUF without bacterial cells. The bioaugmentation treatment significantly increased the number of lubricant-degrading microorganisms in the fishery port seawater microcosm and resulted in rapid removal of waste lubricant No. 2.

    Full Text Available Polish market of small boats has been developed very dynamically in recent years. Market competition forces the shipyards to build new more efficient hull forms and to cut the cost of production as well. This is why modern computer simulation programs are used more often by naval architects. Another trend is to design more universal ships that may be used by larger number of diversified customers. This paper presents project proposal of multipurpose boat hull form. The boat was design to fulfil the requirements imposed by public services like water police, fire brigades, and border guards. It is supposed to be operated on unexplored floodplains and other type shallow waters. The analysis of boat’s motion was based on computer simulations. The resistance curve was evaluated with two methods: comparison study of model test results of similar ships and CFD methods. The results obtained from Ansys Fluent and FINE/Marine systems were compared in this paper. It was shown that taking into consideration dynamic trim and sinkage has a significant impact on free surface capture and resistance values.

    For life forms like us, the most important feature of the Earth is its habitability. Understanding habitability and using that knowledge to locate the nearest habitable planet may be crucial for our survival as a species. Over the past decade, expectations that the universe could be filled with habitable planets have been bolstered by the increasingly large overlap between terrestrial environments known to harbor life and the variety of environments on newly detected rocky exoplanets. The inhabited and uninhabited regions on Earth tell us that temperature and the presence of water are the main constraints that can be used in a habitability classification scheme for rocky planets. Our compilation and review of recent exoplanet detections suggests that the fraction of stars with planets is ~ 100%, and that the fraction with rocky planets may be comparably large. We review extensions to the circumstellar habitable zone including an abiogenesis habitable zone and the galactic habitable zone.

    This report documents the results of the Habitable Volume Workshop held April 18-21, 2011 in Houston, TX at the Center for Advanced Space Studies-Universities Space Research Association. The workshop was convened by NASA to examine the factors that feed into understanding minimum habitable volume requirements for long duration space missions. While there have been confinement studies and analogs that have provided the basis for the guidance found in current habitability standards, determining the adequacy of the volume for future long duration exploration missions is a more complicated endeavor. It was determined that an improved understanding of the relationship between behavioral and psychosocial stressors, available habitable and net habitable volume, and interior layouts was needed to judge the adequacy of long duration habitat designs. The workshop brought together a multi-disciplinary group of experts from the medical and behavioral sciences, spaceflight, human habitability disciplines and design professionals. These subject matter experts identified the most salient design-related stressors anticipated for a long duration exploration mission. The selected stressors were based on scientific evidence, as well as personal experiences from spaceflight and analogs. They were organized into eight major categories: allocation of space; workspace; general and individual control of environment; sensory deprivation; social monotony; crew composition; physical and medical issues; and contingency readiness. Mitigation strategies for the identified stressors and their subsequent impact to habitat design were identified. Recommendations for future research to address the stressors and mitigating design impacts are presented.

    "HABITS—character—fate," this is the summary of Mr. Li, head of the senior high group of the No. 35 High School in Beijing, who has been teaching for dozens of years. He believes the habits that a person cultivates will finally decide his fate. In other words, the most important factor in determining a person’s fate is not his disposition, but his habits. Habits can help change one’s disposition. An ancient admonition says, "The habits
