    It is of fundamental importance for sodium circuits to detect leakages as fast as possible. This is necessary both for small and large leakages. In case of large leakages the level of the free sodium surfaces will decrease quickly. Sodium vapour as well as Na 2 O and NaOH aerosols will cause an alarm of the intallated smoke detectors. With the exception of a leak in an oil-fired sodium heater we never had a large leak due to a rupture of a tube. It seems to us that small leakages, caused by pinholes or a crack are as dangerous for a sodium circuit as large leakage. Small leakages may remain undiscovered for a long time as practice has shown. During that time severe corrosion can occur even in a nitrogen atmosphere which has only a small concentration of oxygen and humidity. Simultaneously an increasing deterioriation by nitriding of the material which is in contact with the sodium vapour will happen probably. As a consequence of nitriding hardness and tensile strength will incease and elongation will be reduced. As observed, a complete rupture of the structural materil in the region of the leak is possible, due to the above-mentioned reasons. We have published some interesting observations we made after dismantling of the KNK steam generator prototype for post-operational metallurgical examinations. The detection of small leakages which may possibly remain unobserved within the thermal insulation during a longer period of time is of high importance with respect to safety of sodium circuits

  5. Could presentism in the histories of psychology actually be futuristic?

    DEFF Research Database (Denmark)

    Valsiner, Jaan; Brinkmann, Svend

    2015-01-01

    Disputes about the origins of psychology in the history of the discipline are functional not for our understanding of the past, but as normative signs that regulate the construction of ideas in the future. We introduce the notion of open-ended normativity that regulates the development of a given...... discipline towards its future. Hence the question of the cultural origins of psychology becomes contested in the 21st century as an important topic. It proves that the history of psychology is an active participant in the making of psychology, as it is creating its future....

  6. Case histories as evidence.

    Herxheimer, Andrew; Healy, David; Menkes, David B

    2012-01-01

    In courts case histories play a central part when a crime may have resulted from an effect of a prescribed drug; in civil cases where a person may have suffered damage from a drug; and in coroners' enquiries into the cause of unexplained deaths. The court must decide two important questions: 1. Can the suspected medication(s) cause this kind of effect? 2. Did it (or they) do so in this particular case? Many judges and coroners have not addressed these questions clearly and have not used expert witnesses consistently, on occasion disregarding scientific evidence. Courts need to appoint experts to explain and interpret the scientific evidence. Few judges are equipped to resolve contradictions between different experts. Brief accounts of five cases from four countries illustrate these points. The reluctance of legal processes to implicate drugs as a possible cause of violent behaviour leads to injustice. Courts must be required to obtain appropriate expert evidence, and be given independent data on which drugs can cause such behaviour.

  7. Toxicity alarm: Case history

    Hogan, D.; Retallack, J.

    1993-01-01

    In late fall 1991, the Novacor petrochemical plant near Joffre, Alberta experienced a toxicity alarm, the first since its startup 14 years ago. Fish exposed to a normal toxicity test were stressed within 2 h and showed 100% mortality after 24 h. A history of the events leading up to, during, and after the toxicity alarm is presented. The major effluent sources were three cooling water systems. Although these sources are well characterized, the event causes were not immediately clear. Initial toxic screening indicated that one was very toxic, another moderately toxic, and the third not toxic at all. All three systems utilized the same chemical treatment program to avoid fouling: stabilized phosphates with minor variants. The most toxic of the cooling systems operated at 10-12 cycles, had three chemicals for biocide control, and had three makeup streams. Toxic and nontoxic system characteristics were compared. An in-depth modified toxicity identification and evaluation program was then performed to identify and evaluate the cause of the toxicity alarm for future prevention. The most probable causes of toxicity were identified by elimination. The combination of high numbers of cycles, hydrocarbons in the makeup water, and bromine added as an antifoulant resulted in formation of aromatic bromamines which are capable of causing the toxic condition experienced. 2 tabs

  8. Aerodynamic instability: A case history

    1985-01-01

    The identification, diagnosis, and final correction of complex machinery malfunctions typically require the correlation of many parameters such as mechanical construction, process influence, maintenance history, and vibration response characteristics. The progression is reviewed of field testing, diagnosis, and final correction of a specific machinery instability problem. The case history presented addresses a unique low frequency instability problem on a high pressure barrel compressor. The malfunction was eventually diagnosed as a fluidic mechanism that manifested as an aerodynamic disturbance to the rotor assembly.

  9. Eyewitness identification in actual criminal cases: an archival analysis.

    Behrman, B W; Davey, S L

    2001-10-01

    This study analyzed 271 actual police cases in order to address several prevalent issues in the eyewitness literature. Suspect identification (SI) rates were obtained for 289 photographic lineups, 258 field showups, 58 live lineups, and 66 lineup identifications preceded by earlier identifications. SI rates were assessed for 3 levels of extrinsic evidence: no extrinsic evidence, evidence of minimal probative value, and evidence of substantial probative value. The SI rates for the photographic lineups were assessed as a function of delay, same vs. cross-race conditions, witness type, and weapon presence. SI rates declined significantly over time; SI rates were significantly greater for the same-race condition. SI rates were much greater for field showups than photographic lineups, 76% vs. 48%. The SI rates for the field showups did not vary as a function of eyewitness conditions. The relation between confidence and suspect/foil identifications for the live lineups was significant and moderately high. The utility of archival identification studies for eyewitness testimony research is discussed.

    The development and implementation of programs in the U.S. to minimize risks and assess unintended consequences of new medications has been increasingly required by the Food and Drug Administration (FDA) since the mid 1990s. This paper provides four case histories of risk management and post-marketing surveillance programs utilized recently to address problems associated with possible abuse, dependence and diversion. The pharmaceutical sponsors of each of these drugs were invited to present their programs and followed a similar template for their summaries that are included in this article. The drugs and presenting companies were OxyContin, an analgesic marketed by Purdue Pharma L.P., Daytrana and Vyvanse, ADHD medications marketed by Shire Pharmaceuticals, Xyrem for narcolepsy marketed by Jazz Pharmaceuticals, and Subutex and Suboxone for opioid dependence marketed by Reckitt Benckiser Pharmaceuticals Inc. These case histories and subsequent discussions provide invaluable real-world examples and illustrate both the promise of risk management programs in providing a path to market and/or for keeping on the market drugs with serious potential risks. They also illustrate the limitations of such programs in actually controlling unintended consequences, as well as the challenge of finding the right balance of reducing risks without posing undue barriers to patient access. These experiences are highly relevant as the FDA increasingly requires pharmaceutical sponsors to develop and implement the more formalized and enforceable versions of the risk management term Risk Evaluation and Mitigation Strategies (REMS).

  11. Denver radium site's - Case history

    International Nuclear Information System (INIS)

    Topolski, T.T.

    1985-01-01

    In developing this case history of the Denver radium sites, an attempt is made to establish the Colorado carnotite connection from the point of discovery to early development and its eventual role in the inception of the National Radium Institute and Denver's radium legacy. Early exploitive mining activities and the exportation of the highest grades of uranium ore to Europe greatly disturbed key officials at the U.S. Bureau of Mines. With its proximity to known carnotite deposits and industrial capacity, Denver's destiny as one of America's early radium production centers became a reality by 1914. With African pitchblend discoveries, Belgium competition spelled the beginning of the end of Denver's romance with radium by 1920. The sites where Denver made or used its radium were lost in obscurity for 60 years and rediscovered in 1979. Thirty one sites and a characterization of their radioactive impact are now a part of the Superfund National Priorities listing for eventual cleanup

  12. Radon remedial techniques in buildings - analysis of French actual cases

    Dupuis, M.

    2004-01-01

    The IRSN has compiled a collection of solutions from data provided by the various decentralised government services in 31 French departments. Contributors were asked to provide a description of the building, as well as details of measured radon levels, the type of reduction technique adopted and the cost. Illustrative layouts, technical drawings and photographs were also requested, when available. Of the cases recorded, 85% are establishments open to the public (schools (70%), city halls (4%) and combined city halls and school houses (26%)), 11% are houses and 4% industrial buildings. IRSN obtained 27 real cases of remedial techniques used. The data were presented in the form of fact sheets. The primary aim of this exercise was to illustrate each of the radon reduction techniques that can be used in the different building types (with basement, ground bearing slab, crawl space). This investigation not only enabled us to show that combining passive and active techniques reduces the operating cost of the installation, but above all that it considerably improves the efficiency. The passive technique reduces the amount of radon in the building and thus reduces the necessary ventilation rate, which directly affects the cost of operating the installation. For the 27 cases recorded, we noted:(a) the application of 7 passive techniques: sealing of floors and semi-buried walls, together with improved aeration by installing ventilation openings or ventilation strips in the windows. Radon concentrations were reduced on average by a factor of 4.7. No measurement in excess of 400 Bq.m -3 (the limit recommended by the French public authorities) was obtained following completion of the works; (b) the application of 15 active techniques: depressurization of the underlying ground, crawl space or basement and/or pressurization of the building. Radon concentrations were reduced on average by a factor of 13.8. Radon concentrations of over 400 Bq.m -3 were measured in only 4 cases

    2013-06-01

    Full Text Available Retroperitoneal fibrosis (RPF is a rare disease of unclear etiology, which is characterized by a chronic non specific inflammation of the retroperitoneum. This inflammation of the retroperitoneum may entrap and obstruct retroperitoneal structures, particularly the ureters. Patients with RPF show non specific clinical symptoms, including poorly localized back pain, general malaise, weight loss, anemia, features of renal failure and occasionally, mild fever. The early symptoms are non specific and an accurate diagnosis is often achieved only subsequent to urological obstruction or the occurrence of renal failure. Although a number of scientific journals devoted to RPF are present in the litera¬ture, there is no accepted diagnostic or therapeutic strategy for this disease. However, there are several therapeutic strate¬gies which have been proven to be effective. Hereby, we reported two cases of retroperitoneal fibrosis which had similar symptoms and findings but different responses to medical treatment .We aimed to discuss challanges of RPF%u2019s diagnosis and the treatment protocol.

    1978-01-01

    Case histories are described in which measurable improvements in the cabin noise environments of the Bell 214B, 206B, and 222 were realized. These case histories trace the noise control efforts followed in each vehicle. Among the design approaches considered, the addition of a fluid pulsation damper in a hydraulic system and the installation of elastomeric engine mounts are highlighted. It is concluded that substantial weight savings result when the major interior noise sources are controlled by design, both in altering the noise producing mechanism and interrupting the sound transmission paths.

  18. DP-THOT - a calculational tool for bundle-specific decay power based on actual irradiation history

    International Nuclear Information System (INIS)

    Johnston, S.; Morrison, C.A.; Albasha, H.; Arguner, D.

    2005-01-01

    A tool has been created for calculating the decay power of an individual fuel bundle to take account of its actual irradiation history, as tracked by the fuel management code SORO. The DP-THOT tool was developed in two phases: first as a standalone executable code for decay power calculation, which could accept as input an entirely arbitrary irradiation history; then as a module integrated with SORO auxiliary codes, which directly accesses SORO history files to retrieve the operating power history of the bundle since it first entered the core. The methodology implemented in the standalone code is based on the ANSI/ANS-5.1-1994 formulation, which has been specifically adapted for calculating decay power in irradiated CANDU reactor fuel, by making use of fuel type specific parameters derived from WIMS lattice cell simulations for both 37 element and 28 element CANDU fuel bundle types. The approach also yields estimates of uncertainty in the calculated decay power quantities, based on the evaluated error in the decay heat correlations built-in for each fissile isotope, in combination with the estimated uncertainty in user-supplied inputs. The method was first implemented in the form of a spreadsheet, and following successful testing against decay powers estimated using the code ORIGEN-S, the algorithm was coded in FORTRAN to create an executable program. The resulting standalone code, DP-THOT, accepts an arbitrary irradiation history and provides the calculated decay power and estimated uncertainty over any user-specified range of cooling times, for either 37 element or 28 element fuel bundles. The overall objective was to produce an integrated tool which could be used to find the decay power associated with any identified fuel bundle or channel in the core, taking into account the actual operating history of the bundles involved. The benefit is that the tool would allow a more realistic calculation of bundle and channel decay powers for outage heat sink planning

  1. Actual evapotranspiration, root extraction, water regime and productivity in the case of lucerne

    International Nuclear Information System (INIS)

    Rambal, S.; Berger, A.; Parisot, J.M.

    1983-01-01

    Measurements were made of the actual evaportranspiration, root extraction and above-ground yield in the case of two varieties of lucerne Medicago sativa L. - Du Puits and Polder - and mixtures of them in equal parts. The daily kinetics of the water potential of the leaves and the collar show that the water regimes of the two varieties are identical in a first approximation. The root systems are different. Polder has the deeper system. The regime of the binary mixture is not simply a juxtaposition of the regimes of the constitutents. Two types of non-linearity were found. The first relates to water flow and the second to productivity. It is postulated that the root systems of the two varieties constituting the mixture undergo plastic deformation, leading to a more efficient resultant system. A system of this type needs, on the other hand, an allocation of photosynthates that would affect its productivity. (author)

    Full Text Available The present study examined the correspondence between perceived and actual social discrimination of overweight people. In total, 77 first-year students provided self-ratings about their height, weight, and perceived social inclusion. To capture actual social inclusion, each participant nominated those fellow students a she/he likes and dislikes and b about whom she/he is likely to hear social news. Students with lower BMI felt socially included, irrespective of their actual social inclusion. In contrast, students with higher BMI felt socially included depending on the degree of their actual social inclusion. Specifically, their felt social inclusion accurately reflected whether they were actually liked/disliked, but only when they were part of social news. When not part of social news, they also showed insensitivity to their actual social inclusion status. Thus, students with a lower BMI tended to be insensitive, while students with a higher BMI showed a differential sensitivity to actual social discrimination.

    The aim of this report is to present photogrammetry as a reliable step in the fabrication of a full-arch immediate rehabilitation. A 59-year-old man attended the department seeking dental rehabilitation for the sequelae of severe oral health neglect. The mandibular teeth suffered from advanced periodontal disease and the patient wore a maxillary complete denture. An irreversible hydrocolloid impression of the mandibular arch was made, poured in stone, and digitally scanned to create the first stereolithography (STL) file. All teeth with the exception of two retained as landmarks were extracted, and seven implants were placed under local anesthesia and their positions recorded using photogrammetry. Maxillary and mandibular dental arch alginate impressions were made, poured in laboratory stone, and scanned. A provisional restoration was placed 7 hours after surgery using the STL files to determine the best-fit line. Radiographic and clinical follow-up after 1 year showed a favorable evolution of the implants. No screw loosening or other mechanical or biologic complications were observed. The case history using the described system suggests certain advantages over conventional techniques. More research is needed to assess the possible benefits associated with photogrammetry when making implant-supported restorations.

  5. Evaluating liquefaction potential. A case history

    International Nuclear Information System (INIS)

    Blystra, A.R.

    1991-01-01

    Several earthen hydropower embankment dams in the midwestern United States were constructed using hydraulic fill methods and are liable to liquefaction during an earthquake due to the use of very loose, saturated sand in the embankment or foundations. A case history is presented describing the methodology used in evaluating the liquefaction potential of the largest earthfill dam in Michigan. The methodology includes the use of standard penetration and cone penetration test data in the formulation of a simplified procedure. Field investigations, laboratory testing, and analyses used are described. In addition to the drilling program, field work included an extensive ground penetrating radar survey, acoustic emission testing, and an electrical resistivity survey. It was found that the lowest calculated factor of safety against liquefaction is 0.63 for a loose zone ca 140 feet below the top of the embankment, and the factor of safety against slope failure, should the zone liquefy, is 1.49. It was concluded that while liquefaction is possible, post earthquake stability is adequate. 6 refs., 3 figs., 1 tab

    Rybach, L.; Muffler, L. J. P.

    The classification of geothermal systems is considered along with the geophysical and geochemical signatures of geothermal systems, aspects of conductive heat transfer and regional heat flow, and geothermal anomalies and their plate tectonic framework. An investigation of convective heat and mass transfer in hydrothermal systems is conducted, taking into account the mathematical modelling of hydrothermal systems, aspects of idealized convective heat and mass transport, plausible models of geothermal reservoirs, and preproduction models of hydrothermal systems. Attention is given to the prospecting for geothermal resources, the application of water geochemistry to geothermal exploration and reservoir engineering, heat extraction from geothermal reservoirs, questions of geothermal resource assessment, and environmental aspects of geothermal energy development. A description is presented of a number of case histories, taking into account the low enthalpy geothermal resource of the Pannonian Basin in Hungary, the Krafla geothermal field in Northeast Iceland, the geothermal system of the Jemez Mountains in New Mexico, and extraction-reinjection at the Ahuachapan geothermal field in El Salvador.

  11. From preferred to actual mate characteristics: the case of human body shape.

    Directory of Open Access Journals (Sweden)

    Alexandre Courtiol

    Full Text Available The way individuals pair to produce reproductive units is a major factor determining evolution. This process is complex because it is determined not only by individual mating preferences, but also by numerous other factors such as competition between mates. Consequently, preferred and actual characteristics of mates obtained should differ, but this has rarely been addressed. We simultaneously measured mating preferences for stature, body mass, and body mass index, and recorded corresponding actual partner's characteristics for 116 human couples from France. Results show that preferred and actual partner's characteristics differ for male judges, but not for females. In addition, while the correlation between all preferred and actual partner's characteristics appeared to be weak for female judges, it was strong for males: while men prefer women slimmer than their actual partner, those who prefer the slimmest women also have partners who are slimmer than average. This study therefore suggests that the influences of preferences on pair formation can be sex-specific. It also illustrates that this process can lead to unexpected results on the real influences of mating preferences: traits considered as highly influencing attractiveness do not necessarily have a strong influence on the actual pairing, the reverse being also possible.

    2007-08-01

    Full Text Available Blogging is a twenty-first century phenomenon that has heralded an age where ordinary people can make their voices heard in the public sphere of the Internet. This article explores blogging as a form of popular history making; the blog as a public history document; and how blogging is transforming the nature of public history and practice of history making in Singapore. An analysis of two Singapore ‘historical’ blogs illustrates how blogging is building a foundation for a more participatory historical society in the island nation. At the same time, the case studies also demonstrate the limitations of blogging and blogs in challenging official versions of history.

  13. Egypt's first subsea completion: A Gulf of Suez case history

    El Hawary, A.; Hoffman, J.G.

    1996-01-01

    A case history of the Gulf of Suez Petroleum Co.'s (Gupco) first subsea completion is provided. The first completion was for Well GS 373-2, a previously drilled and tested exploration well located in the south portion of the gulf of Suez. Subsea technology was used to economically justify development of this one-well marginal field, which was discovered in 1978. Traditional methods proved to be too costly for development, therefore application of a low-cost subsea tree was used to capture the resources. In the Gulf of Suez, many fields have been discovered but have not been developed because of low reserves. These marginal projects can have a profound impact on the revenue and shareholder value if an economic method is used to exploit these opportunities. Platform installation was not feasible because of reserve size, hence the well has remained abandoned until recently. This paper presents a summarized look at subsea completion technology. The cost comparison of traditional development methods will be made, given the local cost structure in Egypt. The application of this technology has some limitations and constraints that will be discussed in the paper. Furthermore, the actual field installation of Egypt's first subsea tree will be summarized. Also included is a discussion on simple remote controls and offshore installation operations

    Full Text Available The paper examines the factors, which affect decision-making on regular personal saving behaviour in the context of an emerging market in Vietnam. Focusing on financial literacy, the paper uses a combined measure of actual financial knowledge and a self-assessment of overall financial knowledge. The sample of the study consists of 240 commercial banks customers selected in 12 branches of four banks in Ho Chi Minh City. The questionnaire covers: (1 actual financial knowledge; (2 self-rating of financial knowledge; (3 financial risk tolerance; and (4 demographic characteristics of the respondents. The results of a logistic regression analysis show that perceived and actual financial literacy have separate effects on regular personal saving. Particularly, actual financial knowledge has a statistically significant positive relationship with regular personal saving with odds ratio higher than 6.5 times. However, perceived financial knowledge and financial risk tolerance factor are not statistically significant with regular personal saving. Finally, this paper offers evidence that the interaction variable, which is used to combine education level with their major study, has a statistically significant relationship with regular personal saving.

  20. Police interviewing and interrogation of juvenile suspects: a descriptive examination of actual cases.

    Cleary, Hayley M D

    2014-06-01

    Although empirical attention to police interrogation has gained traction in recent years, comparatively few studies have examined interrogation of juvenile suspects, and virtually none have examined actual interrogations. Despite a growing literature on youths' interrogation-related capacities, we still know very little about what actually transpires when police question youth. The present study examines electronically recorded police interviews with juveniles to describe the characteristics, processes, and outcomes that occur in actual juvenile interrogations, including interview duration, individuals present, and confessions. Fifty-seven electronic recordings from 17 police departments were analyzed using observational research software. The median juvenile interrogation lasted 46 min, though the range was extensive (6 min to nearly 5 hr). Youth frequently submitted to questioning without a parent or advocate present, and disruptions to the interview process were common. Interrogation outcomes varied and included full confessions, partially incriminating admissions, and denials of guilt. Results from this study provide context for interrogation research using other methods and suggest that youth may frequently consent to interrogation in the absence of important legal protections.

  4. History of Science and Instructional Design: The Case of Electromagnetism

    Science.gov (United States)

    Seroglou, Fanny; Koumaras, Panagiotis; Tselfes, Vassilis

    This paper deals with two main research questions: a) Can we search for pupils'' potential alternative ideas in the history of science and especially in those areas where early scientific ideas were distinct from the current ones? b) Is it possible to overcome pupils'' alternative ideas by using experiments in the classroom, based on early experiments carried out by scientists in the past, in order to promote current scientific ideas? In this paper we present a case study in the field of electromagnetism. From the age of Thales up to the 16th century electrostatic and magnetic phenomena were unified in the context of a ''magic'' idea and were supposed to be of the same nature. Their differences were pointed out during the 16th century by Gardano and Gilbert and the two fields of science were established: electrostatics and magnetism. From the 17th century up to 1830, scientists dealt with the question whether electricities derived from different sources were of the same nature. During 1832-1833, Faraday successfully carried out a number of experiments in order to compare the ability of various electricities to produce the same effects. The above data from the history of science indicated electrostatic, electrodynamic and magnetic phenomena as a field of research on pupils'' and student-teachers'' ideas. The research was carried out in three phases: 10 individual in-depth interviews with 10-14-year-old pupils and 19-21-year-old student-teachers, questionnaire distribution to 109 13-year-old pupils and 148 student-teachers, 10 individual in-depth interviews for further clarification of pupils'' and student-teachers'' reasoning. Research results show that 53% of the student-teachers and 83% of the pupils that were involved in the investigation relate electrostatic with magnetic phenomena, in the same way scientists related these phenomena up to the 16th century. The results also indicate that the lack of common perceptions, commonly observed effects or procedures

    2017-06-01

    Full Text Available A collection of articles written by a well-known orientalist-historian K.A. Pishchulina and published in 2016 includes papers of different years, written on the basis of Persian and Turkic sources reflecting the most pressing issues related to Kazakh khanate. The publishing of this work immediately became a major event in historical scholarship of Kazakhstan. During the Soviet period, the history of this state, as well as of other states created by nomadic peoples, remained poorly understood. Many questions were debatable, since Marxism-Leninism, which was in forefront of science, could not adapt the formational class theory for a nomadic society and nomadic mode of production etc. However, some researchers, including K.A. Pishchulina, were already thinking about these issues. Particularly she studied the role of Turkestan cities as part of Kazakh khanate. According to her main findings, these cities performed a variety of functions being centers of handicraft production, agriculture and trade. As for Turkestan city itself, it was capital and spiritual center of the state, and the management of settled-agricultural population was carried out by various officials. Furthermore, the collection of Pishchulina’s papers discusses management system of nomadic population, tax system of the Khanate. The author comes to a justified conclusion that monetary system needs to be studied further. Next major issue relates to mythologization of Turkic peoples’ history. The books written by amateurs assert that the Golden Horde was a part of Khanate, and Chinggis Khan was a Kazakh. Therefore, several Pishchulina’s articles were published in order to expose these myths. Thus, in this collection the reader would find answers to a variety of questions related to the history of Kazakhstan and adjacent territories and its impact in modern times.

  7. Case histories of microbial induced corrosion

    Energy Technology Data Exchange (ETDEWEB)

    Birketveit, Oe.; Liengen, T.

    2006-03-15

    Recent years bacterial activity has caused process problems and corrosion on several of Hydro s installations in the North Sea. The process problems are related to iron sulphide formed in process equipment and increased oil in discharge water. The corrosion problem is seen in downstream pipelines made of carbon steel, where deposits and formation of biofilm cause the corrosion inhibitor to be ineffective. In most cases the bacteria reproduce in the topside system and especially in the reclaimed oil sump tank. The problems observed, related to bacterial activity, are often a result of how the content from the reclaimed oil sump tank is re-circulated to the process system. Process modifications, changes in biocide treatment strategy, sulphide measurements, cleaning strategy and bio monitoring are presented. (author) (tk)

    2018-01-01

    This paper is based on the analysis of the database of operations from a macro-case on money laundering orchestrated between a core company and a group of its suppliers, 26 of which had already been identified by the police as fraudulent companies. In the face of a well-founded suspicion that more companies have perpetrated criminal acts and in order to make better use of what are very limited police resources, we aim to construct a tool to detect money laundering criminals. We combine Benford's Law and machine learning algorithms (logistic regression, decision trees, neural networks, and random forests) to find patterns of money laundering criminals in the context of a real Spanish court case. After mapping each supplier's set of accounting data into a 21-dimensional space using Benford's Law and applying machine learning algorithms, additional companies that could merit further scrutiny are flagged up. A new tool to detect money laundering criminals is proposed in this paper. The tool is tested in the context of a real case. Copyright © 2017 Elsevier B.V. All rights reserved.

    2015-12-01

    Full Text Available Background: Daily activities within a health care organisation are mediated by information communication processes (ICP involving multiple health care professionals at different levels of care. Effective perinatal management requires critical information to be accurately communicated. If there is a breakdown in this communication patient safety is at risk for various reasons such as: inadequate critical information, misconception of information and uninformed decisions being made. The purpose of this study was to interpret the complexities around ICP in order to contribute to the effective management of the intrapartum period. Methods: Multi method, multiple case study approach was used to understand the ICP during the management of the intrapartum period. During the study, the expected ICP, the actual ICP, the challenges involved and the desired ICP were analysed. Twenty-four in-depth interviews with skilled birth attendants (SBAs employing observer-as-participant roles, field notes, and document review methods were utilised to gather the data. Thematic analysis was utilised to analyse the data using Atlas TI software. Results: The study revealed three subthemes which emerged from the expected ICP, whilst three others that emerged formed the theme actual ICP. The subthemes from the expected ICP included: accessibility of obstetric services, expected referral, recommended tools, expected communication and expected documentation. The theme actual ICP held threee merging subthemes: the handover processes, collaborative information seeking, information communicated and referral processes. Conclusion: This study showed that what was expected was not what was actually happening. The requirements of the policies and protocols need to be effectively implemented to improve practice building these into current biomedical guidelines.

  13. Using History to Teach Mathematics: The Case of Logarithms

    Science.gov (United States)

    Panagiotou, Evangelos N.

    2011-01-01

    Many authors have discussed the question why we should use the history of mathematics to mathematics education. For example, Fauvel (For Learn Math, 11(2): 3-6, 1991) mentions at least fifteen arguments for applying the history of mathematics in teaching and learning mathematics. Knowing how to introduce history into mathematics lessons is a more difficult step. We found, however, that only a limited number of articles contain instructions on how to use the material, as opposed to numerous general articles suggesting the use of the history of mathematics as a didactical tool. The present article focuses on converting the history of logarithms into material appropriate for teaching students of 11th grade, without any knowledge of calculus. History uncovers that logarithms were invented prior of the exponential function and shows that the logarithms are not an arbitrary product, as is the case when we leap straight in the definition given in all modern textbooks, but they are a response to a problem. We describe step by step the historical evolution of the concept, in a way appropriate for use in class, until the definition of the logarithm as area under the hyperbola. Next, we present the formal development of the theory and define the exponential function. The teaching sequence has been successfully undertaken in two high school classrooms.

  15. Case Histories of Landslide Impact: A Database-driven Approach

    Science.gov (United States)

    2015-04-01

    Fundamental understanding of landslide risk requires in-depth knowledge of how landslides have impacted society in the past (e.g., Corominas et al., 2014). A key to obtain insights into the evolution of landslide risk at single facilities of critical infrastructures are case histories of landslide impact. The purpose of such historical analyses is to inform about the site-specific interactions between landslides and land-use activity. Case histories support correlating landslide events and associated damages with multiple control variables of landslide risk, including (i) previous construction works, (ii) hazard awareness, (iii) the type of structure or its material properties, and (iv) measures of post-disaster mitigation. It is a key advantage of case histories to provide an overview of the changes in the exposure and vulnerability of infrastructures over time. Their application helps to learn more about changing patterns in risk culture and the effectiveness of repair or prevention measures (e.g., Klose et al., 2014). Case histories of landslide impact are developed on the basis of information extracted from landslide databases. The use of path diagrams and illustrated flowcharts as data modeling techniques is aimed at structuring, condensing, and visualizing complex historical data sets on landslide activity and land-use. Much of the scientific potential of case histories simply depends on the quality of available database information. Landslide databases relying on a bottom-up approach characterized by targeted local data specification are optimally suited for historical impact analyses. Combined with systematic retrieval, extraction, and integration of data from multiple sources, landslide databases constitute a valuable tool for developing case histories that enable to open a whole new window on the study of landslide impacts (e.g., Damm and Klose, 2014). The present contribution introduces such a case history for a well-known landslide site at a heavily

    After considering the natural history of spleen auto-transplant, a clinical case followed up for seven months with instrumental (echography, scintigraphy) and humoral (Jolly bodies, Heinz bodies, reticulocytes, platelets, complement, immune globulin) examinations has been considered so as to verify "take" and function. One months after reimplantation the patient was again operated on for the onset of an intestinal occlusion due to adherences. On that occasion it was possible to control that the implant had taken. It is concluded that personally used parameters proved to be well correlated and that scintigraphy and echography are two complementary, effective techniques for monitoring auto-transplants.

    Full Text Available Cynicism and skepticism are nowadays conceived as curiosities in the history of philosophical thought, reduced to "eccentric" characters like Diogenes of Sinope and Pyrrho of Elis and a series of anecdotes about them.However, they have gone beyond classical antiquity to the present. Both schools of thought offer a constant challenge to the "official" thought bon ton: mocking and irreverent criticism in the case of the first and extreme relativism in the second.This paper presents an epistemological approach supporting the recovery of the cynicism and the pyrrhonian skepticism principles for the criticism of the historical thought in the modernity It is divided into two parts: the first one shows the broad features of these philosophical trends and the second examines their contributions to historical knowledge based on two cases: Cioran for the cynicism and Veyne for the skepticism.

    Directory of Open Access Journals (Sweden)

    2003-01-01

    Full Text Available The treatment of patients with complex regional pain syndrome (CRPS type 1 is challenging and unpredictable as the condition presents with vascular and neuropathic symptoms after nil or even minor injury to a peripheral nerve. The condition is one of a pain and motor dysfunction. The pathophysiology is not well understood and the relief of symptoms may change from being sympathetically mediated to sympathetically independent during  the course of the disease. At any stage physiotherapy has been advocated as the corner stone and most important aspect of treatment in the rehabilitation of these individuals but unfortunately it has been difficult to execute when pain is exacerbated due to allodynia (unbearable to touch or move and hyperalgesia. Best results have been obtained if the patients are recognised and treated in the early or acute phase and it has been found that through careful assessment and analysis these patients can be recognised by previous events that have occurred in their initial case history. The treatment in the acute stage with physiotherapy modalities such as electrical stimulation and acupuncture will produce an early cessation of the symptoms and prevention of the disease developing into the fully blown CRPS type 1 with irreversible and possibly atrophic consequences. Case histories have been presented that illustrate these important aspects and demonstrate  the value of early and the appropriate physiotherapy that may be more successful than other pharmacological and physical interventions in this disease.

    Five case histories of river channel changes and associated pipeline exposure problems at river and stream crossings in Alberta were discussed with emphasis on the need for proactive inspection. For each case, the different hydrologic and geomorphic factors that resulted in erosion problems were reviewed and the mitigative actions that were taken to solve the problems were described. It was shown that in some cases, there are inherent difficulties in identifying potential erosion problems at the project design stage. It was also demonstrated that systematic monitoring and inspection procedures are useful for planning and implementing remedial measures before problems occur. There are many natural and anthropogenic causes of channel degradation. Upstream progressing degradation is usually the most common problem encountered at pipeline crossings in Alberta. The two main causes are both flood related. They include channel shortening by cutoffs across long meandering loops, and washout of downstream slope controls such as large beaver dams. The five case studies presented in this paper were: (1) North Saskatchewan River crossing near Drayton Valley, (2) Smoky River crossing near Grande Cache, (3) Hells Creek crossing near Grande Cache, (4) Modeste Creek crossing near Breton, and (5) Freeman River crossing near Swan Hills. It was emphasized that pipeline operators must consider past channel changes and geomorphic analysis to predict future channel instability. 15 figs.

  1. The preference and actual use of different types of rural recreation areas by urban dwellers--the Hamburg case study.

    Directory of Open Access Journals (Sweden)

    Thiemen Boll

    Full Text Available In the wake of urbanisation processes and the constitution of metropolitan regions, the role of the city's rural surroundings is receiving more attention from researchers and planners as rural areas offer various (cultural ecosystem services for the urban population. Urban dwellers increasingly desire recreation and landscape experience. Although this need for recreation is generally recognized, few studies have focused on the question of people's preferences for certain types and characteristics of outdoor recreation areas in relation to the frequency of use. In order to acquire baseline data on this subject, the main objectives of this study were to explore recreation preferences of urban dwellers and the relation between actual use and perceived value of recreation areas in a case study in the Hamburg Metropolitan Region (Germany. In a social survey, Hamburg residents (n = 400 were asked about their preferences and use of four important regional recreation areas with different landscape characteristics in face-to-face interviews in different locations in the city. We found that both outdoor recreation within and outside of the city were fairly or very important for more than 70% of the questioned urban dwellers. Interestingly, the preference for a recreation area outside of the city did not depend on the frequency of use, which indicates that certain recreation areas had a symbolic value besides their use value. When people were questioned on the characteristics of recreation areas, perceived naturalness was found to be strongly related to preference. Respondents considered the diversity, uniqueness, and naturalness of the landscape to be far more important than the accessibility of the recreation areas and the provision of service facilities.

    Patient-reported outcomes (PROs) are valuable for effectiveness evaluation, but it is unknown whether the patient views obtained represent the actual case mix. We studied the representativeness of the responses obtained to a routinely administered health-related quality of life (HRQoL) questionnaire in a cardiology unit. Elective coronary artery bypass grafting (CABG; n = 404) and percutaneous coronary intervention (PCI; n = 738) patients operated during June 2012 to August 2014 in the Heart Center, Kuopio University Hospital. The characteristics of the patients with a baseline (n = 260 and 290 for CABG and PCI, respectively) or both baseline and follow-up HRQoL measurements (n = 203 and 189 for CABG and PCI, respectively) were compared with those who did not respond (n = 144 and 448 for CABG and PCI). Baseline questionnaires were less likely obtained from older CABG patients (odds ratio 0.51, 95% confidence interval 0.28-0.91) and those with more severe disease (0.20, 0.05-0.79). Among PCI patients, women (0.64, 0.45-0.91), smokers (0.74, 0.53-1.04), and those with more severe disease (0.26, 0.13-0.52) or more hospital days were underrepresented. Routinely collected PROs in cardiac patients may be biased towards younger and healthier patients. This needs to be recognized when evaluating the representativeness of such data. The routine collection of these data should be adequately resourced.

    Emotions are increasingly inferred linguistically from online data with a goal of predicting off-line behavior. Yet, it is unknown whether emotions inferred linguistically from online communications correlate with actual changes in off-line activity. We analyzed all 886,000 trading decisions and 1,234,822 instant messages of 30 professional day traders over a continuous 2 year period. Linguistically inferring the traders' emotional states from instant messages, we find that emotions expressed in online communications reflect the same distributions of emotions found in controlled experiments done on traders. Further, we find that expressed online emotions predict the profitability of actual trading behavior. Relative to their baselines, traders who expressed little emotion or traders that expressed high levels of emotion made relatively unprofitable trades. Conversely, traders expressing moderate levels of emotional activation made relatively profitable trades.

  13. Actualism and Fictional Characters

    2016-04-01

    Full Text Available http://dx.doi.org/10.5007/1808-1711.2016v20n1p61 In what follows, I present only part of a program that consists in developing a version of actualism as an adequate framework for the metaphysics of intentionality. I will try to accommodate in that framework suggestions found in Kripke’s works and some positions developed by Amie Thomasson. What should we change if we accept “fictional entities” in the domain of the actual world? Actualism is the thesis that everything that exists belongs to the domain of the actual world and that there are no possibilia. I shall defend that there are abstract artefacts, like fictional characters, and institutions. My argument could be seen as a version of Moore’s paradox: it is paradoxical to say: “I made (created it, but I do not believe it exists”. Moreover, there are true sentences about them. I will examine what it means to include abstract artefacts in the domain of the actual world. I favour a use of “exist” that includes beings with no concrete occupation of tri-dimensional space; to exist, it is enough to have been introduced at some moment in history. Abstract artefacts, like fictional characters, exist in that sense. I argue that it is important to distinguish two perspectives (internal and external in order to clarify the kind of knowledge we have of fictional characters. However, their existence presupposes a relation of dependence to a material basis and the mental activities of many people.

  14. Anachronism and the rewriting of history: the South Africa case

    Directory of Open Access Journals (Sweden)

    Georgi Verbeeck

    2006-04-01

    Full Text Available The use and abuse of anachronism is often seen as the quintessence of the writing of history. Historians tend to conceive it as the hardcore of their métier to avoid anachronism. It designates a confusion in order of time, especially the mistake of placing an event, attitude, or circumstance too early. The awareness of historical anachronism is omnipresent in times of a radical rewriting of history, in particular as a result of political transformation. History reflects the needs and ambitions of a political context, and the sense of what is deemed historically significant does not remain unattached hereby. Chronology and anachronism are essential to particular conceptions of history, and if history is in a process of being rewritten, they are the first items to be addressed by the defenders of the old system and the advocates of a new discourse. In political debates on the use or abuse of history anachronism is often seen as ultimate proof of the (un-reliability of new insights and conceptions. As anachronism is defined as a way of transferring contemporary sets of values, assumptions and interpretative categories, every political reorientation inevitably provokes a discussion on that level. If a ‘new nation’ is in search of a ‘new past’, a new reflection on the basic categories of historical thinking becomes necessary. The changing discourses in South African historiography since the end of Apartheid serve here as an illuminative example.

  20. Development case histories: Tongonan and Palinpinon geothermal fields, Philippines

    1992-01-01

    The background on the general scenario of energy resource development in the country is described. Highlights of the exploration history of the Tongonan and Palinpinon geothermal fields in the Philippines are then presented. This is discussed in conjunction with the strategies and policies taken in the development of each field. Finally, the common policies and contrasting development strategies are compared and evaluated. The conclusion derived is that the development strategy decisions at Tongonan are influenced by the regional power demand, topography, and the large extent of the resource. In contrast, the development at Palinpinon is less constrained by the external influence of regional power needs, but, instead, is significantly dominated by the limitations imposed by the rugged terrain and the physical characteristics of the resource area. Such comparison demonstrates the site-specific nature of geothermal development. (auth.). 8 figs.; 2 refs

The mass taken in the second operation is almost competent with radiation necrosis. Following that, he shows no signs of recurrence. Currently, he has returned to full time employment in physical labor. This case suggests effectiveness of BNCT for rather low-grade astrocytomas. (author)

  2. Sustainable geothermal utilization - Case histories; definitions; research issues and modelling

    International Nuclear Information System (INIS)

    Axelsson, Gudni

    2010-01-01

    Sustainable development by definition meets the needs of the present without compromising the ability of future generations to meet their own needs. The Earth's enormous geothermal resources have the potential to contribute significantly to sustainable energy use worldwide as well as to help mitigate climate change. Experience from the use of numerous geothermal systems worldwide lasting several decades demonstrates that by maintaining production below a certain limit the systems reach a balance between net energy discharge and recharge that may be maintained for a long time (100-300 years). Modelling studies indicate that the effect of heavy utilization is often reversible on a time-scale comparable to the period of utilization. Thus, geothermal resources can be used in a sustainable manner either through (1) constant production below the sustainable limit, (2) step-wise increase in production, (3) intermittent excessive production with breaks, and (4) reduced production after a shorter period of heavy production. The long production histories that are available for low-temperature as well as high-temperature geothermal systems distributed throughout the world, provide the most valuable data available for studying sustainable management of geothermal resources, and reservoir modelling is the most powerful tool available for this purpose. The paper presents sustainability modelling studies for the Hamar and Nesjavellir geothermal systems in Iceland, the Beijing Urban system in China and the Olkaria system in Kenya as examples. Several relevant research issues have also been identified, such as the relevance of system boundary conditions during long-term utilization, how far reaching interference from utilization is, how effectively geothermal systems recover after heavy utilization and the reliability of long-term (more than 100 years) model predictions.

    Optical long-baseline interferometry is a unique and powerful technique for astronomical research. Since the 1980's (with I2T, GI2T, Mark I to III, SUSI, ...), optical interferometers have produced an increasing number of scientific papers covering various fields of astrophysics. As current interferometric facilities are reaching their maturity, we take the opportunity in this paper to summarize the conclusions of a few key meetings, workshops, and conferences dedicated to interferometry. We present the most persistent recommendations related to science cases and discuss some key technological developments required to address them. In the era of extremely large telescopes, optical long-baseline interferometers will remain crucial to probe the smallest spatial scales and make breakthrough discoveries.

  5. Case history of MSW-to-energy financings

    Barrett, D.L.

    1993-01-01

    The development of solid waste treatment facilities is dependent upon the developer having sufficient resources to fund the development of a project and the ability of the project to be financed. The access to capital to develop, construct and operate a facility is the key component of the development process. The author is not diminishing the need for long-term waste agreements, the advantages of a superior technology or the benefit of experience. However, without capital, a project will never be initiated and the other components are immaterial. This paper reviews development financing with a case study of an environmental development company with a new technology and project financing with a comparison of four financings of Waste to Energy (WTE) facilities. Prior to reviewing the financings, the components of a project including the participants, agreements, and cash flows are discussed to establish a foundation for the later discussion. The analysis is not intended to be directly applicable to material recovery and composting facilities, however, many issues are common to all environmental facilities

    Cholera, a prototypical secretory diarrheal disease, is an ancient scourge that has both wrought great suffering and taught many valuable lessons, from basic sanitation to molecular signal transduction. Victims experience the voluminous loss of bicarbonate-rich isotonic saline at a rate that may lead to hypovolemic shock, metabolic acidosis, and death within afew hours. Intravenous solution therapy as we know it was first developed in an attempt to provide life-saving volume replacement for cholera patients. Breakthroughs in epithelial membrane transport physiology, such as the discovery of sugar and salt cotransport, have paved the way for oral replacement therapy in areas of the world where intravenous replacement is not readily available. In addition, the discovery of the cholera toxin has yielded vital information about toxigenic infectious diseases, providing a framework in which to study fundamental elements of intracellular signal transduction pathways, such as G-proteins. Cholera may even shed light on the evolution and pathophysiology of cystic fibrosis, the most commonly inherited disease among Caucasians. The goal of this paper is to review, using case studies, some of the lessons learned from cholera throughout the ages, acknowledging those pioneers whose seminal work led to our understanding of many basic concepts in medical epidemiology, microbiology, physiology, and therapeutics.

    The Burn Unit of Dona Estefânia Hospital admitted a total of 454 patients from January 1992 to January 1995, 24 of these patients suffered from electric shock. Of these 24 patients 3 suffered burns in the mouth, 15 in one or both hands and 6 multiple burns. In 19 patients the burns were up to 1%. A description is made of 5 cases, male children between the ages of 9 and 13 years, which were deemed severe. The incidents occurred outdoors with different voltages and in activities considered of ludic or experimental nature: two on the roof of a house, two with railway cables and one with an electrical cable in a port zone. The burnt areas vary between 4% and 70%, all of them 2nd and 3rd degree, with hospitalization lasting from 36 to 116 days. In addition to early and coordinated medical and rehabilitative treatment, according to individual needs, a description is also made of the cutaneous sequelae (deforming cicatrices, bridles), neurologic and psychologic sequelae, with emphasis on a patient who underwent amputation of the lower left leg and 4th and 5th ranges of the right foot. It was concluded that measures should be taken in education and legislation to prevent these accidents. Relevance is given to the need for a multidisciplinary team and specialized center for the treatment of these patients.

  8. Bioremediation of contaminated soil: Strategy and case histories

    International Nuclear Information System (INIS)

    Balba, M.T.; Ying, A.C.; McNeice, T.G.

    1991-01-01

    Microorganisms are capable of degrading many kinds of xenobiotic compounds and toxic chemicals. These microorganisms are ubiquitous in nature and there are numerous cases in which long-term contamination of soil and groundwater has been observed. The persistence of the contamination is usually caused by the inability of micro-organisms to metabolize these compounds under the prevailing environmental conditions. Two general reasons account for the failure of microbes to degrade pollutants in any environment: (1) inherent molecular recalcitrance of the contaminants and (2) environmental factors. The inherent molecular recalcitrance is usually associated with xenobiotic compounds where the chemical structure of the molecule is such that microbes and enzymes required for its catabolism have not evolved yet in nature. The environmental factors include a range of physicochemical conditions which influence microbial growth and activity. Biological remediation of contaminated sites can be accomplished using naturally-occurring microorganisms to treat the contaminants. Only particular groups of microorganisms are capable of decomposing specific compounds. The development of a bioremediation program for a specific contaminated soil system usually includes: thorough site/soil/waste characterization; treatability studies; and design and implementation of the bioremediation plan. The results of in situ and ex situ treatment programs involving the cleanup of petroleum hydrocarbon-contaminated soil will be discussed in detail. The paper will address key issues affecting the success of the bioremediation process such as nutrient transport, metal precipitation and potential soil clogging, microbial inoculation, etc

    2015-12-01

    The incidence of melanoma in Denmark has immensely increased over the last 10 years making Denmark a high risk country for melanoma. In the last two decades multiple public campaigns have sought to increase the awareness of melanoma. Family history of melanoma is a known major risk factor but previous studies have shown that self-reported family history of melanoma is highly inaccurate. These studies are 15 years old and we wanted to examine if a higher awareness of melanoma has increased the accuracy of self-reported family history of melanoma. We examined the family history of 181 melanoma probands who reported 199 cases of melanoma in relatives, of which 135 cases where in first degree relatives. We confirmed the diagnosis of melanoma in 77% of all relatives, and in 83% of first degree relatives. In 181 probands we validated the negative family history of melanoma in 748 first degree relatives and found only 1 case of melanoma which was not reported in a 3 case melanoma family. Melanoma patients in Denmark report family history of melanoma in first and second degree relatives with a high level of accuracy with a true positive predictive value between 77 and 87%. In 99% of probands reporting a negative family history of melanoma in first degree relatives this information is correct. In clinical practice we recommend that melanoma diagnosis in relatives should be verified if possible, but even unverified reported melanoma cases in relatives should be included in the indication of genetic testing and assessment of melanoma risk in the family.

    2014-01-01

    The ministerial ordinance relating to the Nuclear Reactor Regulation Law, revised in 2012, requires licensees of nuclear facilities to establish a system to foster Nuclear Security Culture. However, such measures are introduced without thorough consideration of essentials of Nuclear Security Culture. This report aims to provide deeper understanding of the concept and raise issues relating to implementation of nuclear security measures by reviewing the Implementing Guide of Nuclear Security Culture published by International Atomic Energy Agency and related documents, as well as analyzing security threats that actually happened recently. The results are summarized as follows: 1) Two beliefs, namely, 'a credible threat exists' and 'nuclear security is important', form the basis of Nuclear Security Culture. Nuclear Security Culture bears a high degree of resemblance to Nuclear Safety Culture because the both assume the same organizational culture model. The differences between the two are derived from whether the malevolence of adversaries should be taken into consideration or not. As the questioning attitude plays an important role to implant the two beliefs, a proper management system of Nuclear Security Culture is necessary to cultivate it. 2) Based on the related documents and an analysis of the cases of actual threats, the following viewpoints should be made clear: (a) the role of the actors of Nuclear Security Culture, (b) flexible sensitivity to share the same understanding about the credible threat, (c) systematic revision of the related regulation about sensitive information management and security clearance of the personnel, and complementary measures such as hotline, (d) measures to encourage the positive action of the personnel, (e) how to construct continuous cycle of improvement of Nuclear Security Culture at state level.

    1986-01-01

    This report documents a case history in which a cadaver and the associated burial objects were found to be well-preserved after more than 2100 years of burial in Southern China. The preservation was attributed to the presence of a 60-300 cm thick kaolin or white clay layer around the tomb, which acted effectively as a barrier to moisture and air percolation. The degree of preservation in other tombs of similar age in the same area apparently depended on the mineralogy and thickness of the clay sealants used. The implication of this case history to nuclear fuel waste disposal is discussed

    Full Text Available The Tinnitus Sample Case History Questionnaire was determined as a standardized questionnaire for obtaining patient case histories and for characterizing patients into subgroups at the Tinnitus Research Initiative in 2006. In this study, we developed a Japanese version of this questionnaire for evaluating the clinical characteristics of patients with tinnitus. The Japanese version of the questionnaire will be available for evaluating treatments for tinnitus and for comparing data on tinnitus in research centers.To evaluate the clinical characteristics of patients with tinnitus in Japan using a newly developed Japanese version of Tinnitus Sample Case History Questionnaire.This was a prospective study based on patient records.University hospitals, general hospitals, and clinics.We collected patient data using a Japanese translated version of the Tinnitus Sample Case History Questionnaire. In total, 584 patients who visited our institutions in Japan between August 2012 and March 2014 were included (280 males and 304 females; age 13-92 years; mean age, 60.8. We examined patients after dividing them into two groups according to the presence or absence of hyperacusis. The collected results were compared with those from the Tinnitus Research Initiative database.Compared with the TRI database, there were significantly more elderly female patients and fewer patients with trauma-associated tinnitus. There was a statistically lower ratio of patients with hyperacusis. We found that patients with tinnitus in addition to hyperacusis had greater tinnitus severity and exhibited higher rates of various complications.The Japanese version of the Tinnitus Sample Case History Questionnaire developed in this study can be a useful tool for evaluating patients with tinnitus in Japan. The results of this multicenter study reflect the characteristics of patients with tinnitus who require medical care in Japan. Our data provides a preliminary basis for an international

    2017-10-01

    Full Text Available A new modeling method for high voltage direct current (HVDC systems and associated controllers is presented for the power system simulator for engineering (PSS/E simulation environment. The aim is to improve the estimation of the transient DC voltage and current in the event of an AC line-to-ground fault. The proposed method consists primary of three interconnected modules for (a equation conversion; (b control-mode selection; and (c DC-line modeling. Simulation case studies were carried out using PSS/E and a power systems computer aided design/electromagnetic transients including DC (PSCAD/EMTDC model of the Jeju– Haenam HVDC system in Korea. The simulation results are compared with actual operational data and the PSCAD/EMTDC simulation results for an HVDC system during single-phase and three-phase line-to-ground faults, respectively. These comparisons show that the proposed PSS/E modeling method results in the improved estimation of the dynamic variation in the DC voltage and current in the event of an AC network fault, with significant gains in computational efficiency, making it suitable for real-time analysis of HVDC systems.

Twenty-four first-year audiology students, five simulated patients, two clinical educators, and three evaluators. The Audiology Simulated Patient Interview Rating Scale (ASPIRS) was developed consisting of six items assessing specific clinical skills, non-verbal communication, verbal communication, interpersonal skills, interviewing skills, and professional practice skills. These items are applied once for taking a case history and again for giving feedback. The ASPIRS showed very high internal consistency (α = 0.91-0.97; mean inter-item r = 0.64-0.85) and fair-to-moderate agreement between evaluators (29.2-54.2% exact and 79.2-100% near agreement; κ weighted up to 0.60). It also showed fair-to-moderate absolute agreement amongst evaluators for single evaluator scores (intraclass correlation coefficient [ICC] r = 0.35-0.59) and substantial consistency of agreement amongst evaluators for three-evaluator averaged scores (ICC r = 0.62-0.81). Factor analysis showed the ASPIRS' 12 items fell into two components, one containing all feedback items and one containing all case history items. The ASPIRS shows promise as the first published tool for assessing audiology students taking a case history and giving feedback with an SP.

    Older adults treated with warfarin are prone to complications, and high-quality monitoring is essential. The aim of this case history based study was to assess the quality of warfarin monitoring in a routine situation, and in a situation with an antibiotic-warfarin interaction, before and after receiving an electronic alert. In April 2014, a national web-based survey with two case histories was distributed among Norwegian nursing home physicians and general practitioners working part-time in nursing homes. Case A represented a patient on stable warfarin treatment, but with a substantial INR increase within the therapeutic interval. Case B represented a more challenging patient with trimethoprim sulfamethoxazole (TMS) treatment due to pyelonephritis. In both cases, the physicians were asked to state the next warfarin dose and the INR recall interval. In case B, the physicians could change their suggestions after receiving an electronic alert on the TMS-warfarin interaction. Three hundred and ninety eight physicians in 292 nursing homes responded. Suggested INR recall intervals and warfarin doses varied substantially in both cases. In case A, 61% gave acceptable answers according to published recommendations, while only 9% did so for case B. Regarding the TMS-warfarin interaction in case history B, the electronic alert increased the percentage of respondents correctly suggesting a dose reduction from 29% to 53%. Having an INR instrument in the nursing home was associated with shortened INR recall times. Practical advice on handling of warfarin treatment and drug interactions is needed. Electronic alerts as presented in electronic medical records seem insufficient to change practice. Availability of INR instruments may be important regarding recall time.

  4. HEART OF MYTH - HEART OF SCIENCE Part I: Harriet Martineau's cardiac symptoms: a Victorian case history.

    Science.gov (United States)

    Bound Alberti, Fay

    This article explores the history and meanings of the heart and its diseases as aspects of the histories of science and emotion. Analyzing the twofold meanings of the heart as both bodily object and cultural symbol, it explores the reasons for the apparent conflict in meanings of the heart of science and the heart of emotion in Western medical culture since the 19th century. In Part I, a case study of the writer, economist, and philosopher Harriet Martineau is used to demonstrate and trace that conflict, while Part II highlights the manifold meanings of the heart both in the past and in the present.

  5. History as a biomedical matter: recent reassessments of the first cases of Alzheimer's disease.

    This paper examines medical scientists' accounts of their rediscoveries and reassessments of old materials. It looks at how historical patient files and brain samples of the first cases of Alzheimer's disease became reused as scientific objects of inquiry in the 1990s, when a genetic neuropathologist from Munich and a psychiatrist from Frankfurt lead searches for left-overs of Alzheimer's 'founder cases' from the 1900s. How and why did these researchers use historical methods, materials and narratives, and why did the biomedical community cherish their findings as valuable scientific facts about Alzheimer's disease? The paper approaches these questions by analysing how researchers conceptualised 'history' while backtracking and reassessing clinical and histological materials from the past. It elucidates six ways of conceptualising history as a biomedical matter: (1) scientific assessments of the past, i.e. natural scientific understandings of 'historical facts'; (2) history in biomedicine, e.g. uses of old histological collections in present day brain banks; (3) provenance research, e.g. applying historical methods to ensure the authenticity of brain samples; (4) technical biomedical history, e.g. reproducing original staining techniques to identify how old histological slides were made; (5) founding traditions, i.e. references to historical objects and persons within founding stories of scientific communities; and (6) priority debates, e.g. evaluating the role particular persons played in the discovery of a disease such as Alzheimer's. Against this background, the paper concludes with how the various ways of using and understanding 'history' were put forward to re-present historic cases as 'proto-types' for studying Alzheimer's disease in the present.

    We tested the significance of psychic factors in the etiopathogenesis of alopecia areata. We analysed the patient on the basis of a detailed examination based on the case history, including important events in his/her life, personality traits, serious events and the loss of emotional attachment. General important events happened to 80% of the patients, personality traits able to cause the disease were present in 73%, serious events in 62% and the loss of emotional attachment was also found in 62% of the patients. We tested 60 patients (31 women and 29 men). The evidence obtained from the detailed examination based on case histories indicated significantly frequent occurrence of the psychic factors preceding the occurrence of alopecia areata.

    2006-01-01

    Background Methods for analyzing space-time variation in risk in case-control studies typically ignore residential mobility. We develop an approach for analyzing case-control data for mobile individuals and apply it to study bladder cancer in 11 counties in southeastern Michigan. At this time data collection is incomplete and no inferences should be drawn – we analyze these data to demonstrate the novel methods. Global, local and focused clustering of residential histories for 219 cases and 437 controls is quantified using time-dependent nearest neighbor relationships. Business address histories for 268 industries that release known or suspected bladder cancer carcinogens are analyzed. A logistic model accounting for smoking, gender, age, race and education specifies the probability of being a case, and is incorporated into the cluster randomization procedures. Sensitivity of clustering to definition of the proximity metric is assessed for 1 to 75 k nearest neighbors. Results Global clustering is partly explained by the covariates but remains statistically significant at 12 of the 14 levels of k considered. After accounting for the covariates 26 Local clusters are found in Lapeer, Ingham, Oakland and Jackson counties, with the clusters in Ingham and Oakland counties appearing in 1950 and persisting to the present. Statistically significant focused clusters are found about the business address histories of 22 industries located in Oakland (19 clusters), Ingham (2) and Jackson (1) counties. Clusters in central and southeastern Oakland County appear in the 1930's and persist to the present day. Conclusion These methods provide a systematic approach for evaluating a series of increasingly realistic alternative hypotheses regarding the sources of excess risk. So long as selection of cases and controls is population-based and not geographically biased, these tools can provide insights into geographic risk factors that were not specifically assessed in the case

    We report the clinical case of a 55 year-old male patient, with a previous history of nephrectomy by hypernephroma sixteen years ago, first presenting hypercalcemia and rising of intact parathyroid hormone (iPTH) levels. A localization study revealed an intrathyroid nodule with cystic appearance. After undergoing a hemi-thyroidectomy, the patient is diagnosed with parathyroid carcinoma. This article analyzes previously published cases presenting parathyroidal pathologies associated with hypernephroma. A broader differential diagnosis--including the screening of parathyroidal pathologies should be considered in patients with hypercalcemia and hypernephroma.

    2016-06-01

    The actual evapotranspiration was modelled utilizing the boreal ecosystem productivity simulator (BEPS) in Huaihe River Basin from 2001 to 2012. In the meantime, the quantitative analyses of the spatial-temporal variations of actual evapotranspiration characteristics and its influencing factors under different vegetation types were conducted. The results showed that annual evapotranspiration gradually decreased from southeast to northwest, tended to increase annually, and the monthly change for the average annual evapotranspiration was double-peak curve. The differences of evapotranspiration among vegetation types showed that the farmland was the largest contributor for the evapotranspiration of Huaihe Basin. The annual actual evapotranspiration of the mixed forest per unit area was the largest, and that of the bare ground per unit area was the smallest. The changed average annual evapotranspiration per unit area for various vegetation types indicated an increased tendency other than the bare ground, with a most significant increase trend for the evergreen broadleaf forest. The thermodynamic factors (such as average temperature) were the dominant factors affecting the actual evapotranspiration in the Huaihe Basin, followed by radiation and moisture factors.

  13. Cerebral metastasis masquerading as cerebritis: A case of misguiding history and radiological surprise!

    Directory of Open Access Journals (Sweden)

    Ashish Kumar

    2013-01-01

    Full Text Available Cerebral metastases usually have a characteristic radiological appearance. They can be differentiated rather easily from any infective etiology. Similarly, positive medical history also guides the neurosurgeon towards the possible diagnosis and adds to the diagnostic armamentarium. However, occasionally, similarities on imaging may be encountered where even history could lead us in the wrong direction and tends to bias the clinician. We report a case of a 40-year-old female with a history of mastoidectomy for otitis media presenting to us with a space occupying lesion in the right parietal region, which was thought pre-operatively as an abscess along with the cerebritis. Surprisingly, the histopathology proved it to be a metastatic adenocarcinoma. Hence, a ring enhancing lesion may be a high grade neoplasm/metastasis/abscess, significant gyral enhancement; a feature of cerebritis is not linked with a neoplastic etiology more often. This may lead to delayed diagnosis, incorrect prognostication and treatment in patients having coincidental suggestive history of infection. We review the literature and highlight the key points helping to differentiate an infective from a neoplastic pathology which may look similar at times.

    2010-07-01

    This paper discussed approaches to tank farm ground improvement via 3 Canadian ground improvement case histories in order to set forth the advantages of ground improvement for foundation support at petroleum storage tank facilities. Each case study featured a particular set of site conditions, performance criteria, and ground improvement techniques selected to attain the desired foundation performance. The first case study involved a Vibro Replacement stone column to meet strict seismicity requirements, the second employed Dynamic Compaction to mitigate deep variable fill within a former gravel pit, and the last encompassed Vibro Compaction applied to a site with a sand fill soil profile. The site conditions, the design requirements, the ground improvement solution, the execution, and the quality control techniques and results were presented for each case history. Soil reinforcement and ground improvement to treat loose and soft soils below heavy storage tanks can be an economical solution to foundation design challenges. However, it is important to select proper methods and tailor the densification programs to the specific subsoil conditions and design requirements. In each application, the selected ground improvement technique exceeded the specified in-situ testing requirements. 3 refs., 9 figs.

    Genome-wide association studies (GWAS) of schizophrenia have yielded more than 100 common susceptibility variants, and strongly support a substantial polygenic contribution of a large number of small allelic effects. It has been hypothesized that familial schizophrenia is largely a consequence of inherited rather than environmental factors. We investigated the extent to which familiality of schizophrenia is associated with enrichment for common risk variants detectable in a large GWAS. We analyzed single nucleotide polymorphism (SNP) data for cases reporting a family history of psychotic illness (N = 978), cases reporting no such family history (N = 4,503), and unscreened controls (N = 8,285) from the Psychiatric Genomics Consortium (PGC1) study of schizophrenia. We used a multinomial logistic regression approach with model-fitting to detect allelic effects specific to either family history subgroup. We also considered a polygenic model, in which we tested whether family history positive subjects carried more schizophrenia risk alleles than family history negative subjects, on average. Several individual SNPs attained suggestive but not genome-wide significant association with either family history subgroup. Comparison of genome-wide polygenic risk scores based on GWAS summary statistics indicated a significant enrichment for SNP effects among family history positive compared to family history negative cases (Nagelkerke’s R2 = 0.0021; P = 0.00331; P-value threshold history positive compared to family history negative cases (0.32 and 0.22, respectively; P = 0.031).We found suggestive evidence of allelic effects detectable in large GWAS of schizophrenia that might be specific to particular family history subgroups. However, consideration of a polygenic risk score indicated a significant enrichment among family history positive cases for common allelic effects. Familial illness might, therefore, represent a more heritable form of schizophrenia, as suggested by

    The installation of liners for vertical barriers is difficult and has been a learning experience for every contractor making the attempt. Soil stratigraphy and hydrogeologic conditions can vary over short distances, creating a variety of problems. This is particularly so when working near landfills and documentation of the as-built condition is poor. Successful installation requires detailed planning and knowledge of what to expect, as well as alternate plans for potential problems. Several successful methods of panel connection will be presented as well as a variety of installation techniques. Project case histories will be reviewed, highlighting the challenges associated with specific construction techniques

    Full Text Available Organophosphate (OP poisoning is common in India. Only few case reports of parenteral OP poisoning have been described. We report a case of self-injected methyl parathion poisoning, presenting after four days with seizure, altered sensorium, and respiratory distress which posed a diagnostic and therapeutic dilemma. Despite nonavailability of history of OP poisoning, he was treated based on suspicion and showed a good clinical response to treatment trial with atropine and pralidoxime, and had a successful recovery. Atypical presentations may be encountered following parenteral administration of OP poison, and even a slight suspicion of this warrants proper investigations and treatment for a favorable outcome. Persistently low plasma cholinesterase level is a useful marker for making the diagnosis.

    A national audit of sexual history-taking was conducted in genitourinary medicine clinics in the UK in 2008. Data were aggregated by region and clinic, allowing practice to be compared between regions, as well as to national averages and against national Guidelines. In this paper the case-notes of 4121 patients were audited. A high proportion of the case-notes were deemed to be completely legible. In other respects there is considerable inter-regional variation in the adherence to national Guidelines. Interventions are especially required to improve documentation of practice in discussing condom use, HIV risk assessment, offer of a chaperone and assessment for hepatitis B vaccination and hepatitis C testing, and issues concerning sexual contacts.

  6. Haptic and Olfactory Experiences of the Perth Foreshore: Case Studies in Sensory History

    Saren Reid

    2015-11-01

    Full Text Available The liminal zone where a city meets ‘the water’s edge’ is a place of heightened sensory experiences. In Australia, these settings have been continually reshaped and experienced, individually and collectively, both before and after European settlement, and so they provide a physical domain for reinterpreting Australian history. In Perth, Western Australia, at the turn of the twentieth century, two recreational buildings on the foreshore, the Perth City Baths (1898–1914 and the Water Chute (1905–unknown, promoted new aquatic leisure practices that provided heightened sensory experiences of the Swan River and the city foreshore. These buildings are examined from the perspective of ‘sensory history’, an alternative form of cultural and environmental analysis that has been garnering interest from a range of disciplines over the past several decades (see, for example, the work of Constance Classen, Alain Corbin, David Howes and Mark M Smith. Sensory history seeks to reveal through historical inquiry the informative and exploratory nature of the senses in specific contexts. The potential value of sensory history to studies of built and natural environments lies in drawing attention away from the overweening and frequently generalising dominance of ‘the visual’ as a critical category in humanities research. The case studies explore how evolving swimming practices at the City Baths and ‘shooting the chutes’ at the Water Chute provided novel, exciting and sometimes unpleasant haptic and olfactory experiences and consider how changing forms of recreation allowed for broadly sensuous rather than primarily visual experiences of the foreshore and Swan River. These case studies are part of a larger body of research that seeks to ‘make sense’ of the Perth foreshore and, more broadly, Australian urban waterfronts as sites of varied and evolving sensory experience.

    A field investigation was performed to retest liquefaction and nonliquefaction sites from the 1976 Tangshan earthquake in China. These sites were carefully investigated in 1978 and 1979 by using standard penetration test (SPT) and cone penetration test (CPT) equipment; however, the CPT measurements are obsolete because of the now nonstandard cone that was used at the time. In 2007, a modern cone was mobilized to retest 18 selected sites that are particularly important because of the intense ground shaking they sustained despite their high fines content and/or because the site did not liquefy. Of the sites reinvestigated and carefully reprocessed, 13 were considered accurate representative case histories. Two of the sites that were originally investigated for liquefaction have been reinvestigated for cyclic failure of fine-grained soil and removed from consideration for liquefaction triggering. The most important outcome of these field investigations was the collection of more accurate data for three nonliquefaction sites that experienced intense ground shaking. Data for these three case histories is now included in an area of the liquefaction triggering database that was poorly populated and will help constrain the upper bound of future liquefaction triggering curves. ?? 2011 American Society of Civil Engineers.

    Molan, M.; Molan, G.

    2001-01-01

    Adaptation of working environment (social, organizational, physical and physical) should assure higher level of workers' availability and consequently higher level of workers' performance. A special theoretical model for description of connections between environmental factors, human availability and performance was developed and validated. The central part of the model is evaluations of human actual availability in the real working situation or fitness for duties self-estimation. The model was tested in different working environments. On the numerous (2000) workers, standardized values and critical limits for an availability questionnaire were defined. Standardized method was used in identification of the most important impact of environmental factors. Identified problems were eliminated by investments in the organization in modification of selection and training procedures in humanization of working .environment. For workers with behavioural and health problems individual consultancy was offered. The described method is a tool for identification of impacts. In combination with behavioural analyses and mathematical analyses of connections, it offers possibilities to keep adequate level of human availability and fitness for duty in each real working situation. The model should be a tool for achieving adequate level of nuclear safety by keeping the adequate level of workers' availability and fitness for duty. For each individual worker possibility for estimation of level of actual fitness for duty is possible. Effects of prolonged work and additional tasks should be evaluated. Evaluations of health status effects and ageing are possible on the individual level. (author)

    The Waterloo Barrier trademark steel sheet piling (patents pending) incorporates a cavity at each interlocking joint that is flushed clean and injected with sealant after the piles have been driven into the ground to form a vertical cutoff wall. The installation and sealing procedures allow for a high degree of quality assurance and control. Bulk wall hydraulic conductivities of 10 -8 to 10 -10 cm/sec have been demonstrated at field installations. Recent case histories are presented in which Waterloo Barrier trademark cutoff walls are used to prevent off-site migration of contaminated groundwater or soil gases to adjacent property and waterways. Full enclosures to isolate DNAPL source zones or portions of contaminated aquifers for pilot-scale remediation testing will also be described. Monitoring data will be used to demonstrate the effectiveness of the Waterloo Barrier trademark in these applications

    Long-term follow-up reports on chondroid lesions of the skull base are rarely presented in the literature. There are virtually no data on natural growth rates of these tumors based on MRI obtained over a period of 10 years or longer. We followed a patient who has had such a lesion for more than 12 years. A non-progressive, slight abducens palsy has been the only associated symptom so far. Even though the patient was operated on for an additional intracranial arterio-venous malformation, clinical features and chromosomal testing excluded Maffucci's syndrome. The MRI follow-up in this case provides an extraordinary perspective on the natural history of chondroid skull base tumors. (orig.)

    2009-10-01

    Crimean-Congo hemorrhagic fever (CCHF) is a tick-borne viral disease presenting with flu-like symptoms, fever, hemorrhage and petechia. The virus (CCHFV) is a member of the Nairovirus genera of Bunyaviridae family and can be transmitted to humans by Hyalomma tick-bite, by exposure to infected blood and fomites of patient with CCHF or contact with animal tissue in viremic phase. In this study we present two cases with CCHF but without history of tick bite or exposure to infected fomites, even not coming from endemic areas. The first case was a 67 years old male patient presented with fever, fatique and shortness of breath. Physical examination revealed rales in right lower segments of lung. Laboratory findings showed elevation of liver enzymes with thrombocytopenia and prolonged prothrombin time. Serological markers for viral hepatitis, cytomegalovirus (CMV) and Epstein-Barr virus (EBV) were negative. The patient was found to be IgM and RNA positive for CCHFV by ELISA and polymerase chain reaction (PCR) methods, respectively. His history indicated a contact with livestock. The second patient was a 60 years old male dealing with husbandry. He had fever, fatique and myalgia. Physical examination revealed petechial rash on legs. Laboratory findings showed elevated liver enzymes, prolonged phrothrombin time and thrombocytopenia. Viral hepatitis markers, CMV-IgM and EBV-IgM were found negative. He was also found to be IgM and RNA positive for CCHFV in the reference laboratory. In conclusion, CCHF should be considered in the differential diagnosis of patients who contact with livestock and present with fever, fatigue, rash, elevated liver enzymes, thrombocytopenia and prolonged prothrombin time eventhough they do not reside in endemic areas for CCHF.

    Genome-wide association studies (GWAS) of schizophrenia have yielded more than 100 common susceptibility variants, and strongly support a substantial polygenic contribution of a large number of small allelic effects. It has been hypothesized that familial schizophrenia is largely a consequence...... of inherited rather than environmental factors. We investigated the extent to which familiality of schizophrenia is associated with enrichment for common risk variants detectable in a large GWAS. We analyzed single nucleotide polymorphism (SNP) data for cases reporting a family history of psychotic illness (N...... history subgroup. Comparison of genome-wide polygenic risk scores based on GWAS summary statistics indicated a significant enrichment for SNP effects among family history positive compared to family history negative cases (Nagelkerke's R2=0.0021; P=0.00331; P-value threshold

    2015-12-01

    Full Text Available Art and science, over the centuries, though starting from different positions, have very often led to the same conclusions. History, on the other hand, establishes identities that derive from our past and allows for exchanges and unity between people of different nationalities, in both a commercial and scientific context, in a world without borders, in spite of obvious contradictions related to this globalized world. The case of Italy-China bears witness to this in a significant way.A case in point is represented by the scientific collaboration between the Alma Mater University of Bologna and Zhejiang University, as well as that between the Salesian Pontifical University of Rome and Fudan University in Shanghai, Zhejiang University and the Foreign Studies University of Beijing.In the first case, the ongoing research project “Historical anamnesis, preservation and valorization of the statues of the Longxing Buddhist Temple of Qingzhou (China” is being carried out between the Department of Cultural Heritage Diagnostic Laboratory for Cultural Heritage of the University of Bologna and the Cultural Heritage Institute of Zhejiang University. In the second case, collaboration between the Salesian Pontifical University and the Chinese Universities, covers activities relating to the study of philosophy, pedagogy and Latin language and literature.The paper highlights the importance of drawing value of a cultural, conservative, social, identitary nature within the context of the holistic value of cultural heritage and respecting ethical aspects at a personal and interpersonal level, in particular, by offering young people the opportunity to enter the employment market and of which they are currently experiencing all the problematic fluctuations.

  17. Remaining life case history studies for high energy piping systems using equivalent stress

    Cohn, M.J.

    1987-01-01

    As the development of plant life extension for high energy piping systems is progressing, conventional piping system design methodologies are also being reevaluated. Traditional guidelines such as American National Standard Institute/American Society of Mechanical Engineers B31.1 (ANSI/ASME) were developed for plants having design lives in the 25- to 30-year regime based upon relatively short-term base metal creep data. These guidelines use a simplified approach for the piping analysis. Two types of stress criteria must be satisfied. The first type is longitudinal plus torsion stress checks for several types of loading conditions versus the material allowable stresses. The second type is an independent minimum wall thickness check which considers the hoop stress versus the material allowable stress. Seven case histories have been evaluated to estimate the minimum piping system creep life based on the current ANSI/ASME B31.1 finite element type of analysis, which is a traditional approach, versus a multiaxial stress state type of analysis. In nearly every case, the equivalent stress methodology predicted significantly higher stresses. Consequently, the equivalent stress methodology resulted in 11 to 96% lower time to rupture values as compared to the values predicted using ANSI/ASME B31.1 stresses

    There is an increasing awareness of the role played by the food retail characteristics in determining individuals' healthy food purchasing and consumption behaviors. The perceived costs of healthier food alternatives have been shown to contribute negatively to individual's food choices in developed societies. However, there is still a dearth of knowledge regarding this phenomenon in low to middle income countries particularly in Africa. This study explored health club member's experiences in buying healthier food options and compared their perceived cost of selected healthier and less healthy foods with actual market costs in a South African township. A cross-sectional study design using quantitative and qualitative research methods. The study was conducted in Khayelitsha, a township in the Western Cape Province in South Africa. Participants were 50 members of a health club, mostly female and above 50 years of age. The study was conducted in three phases. The first phase involved interviews with all 50 health club members. During the second phase ten purposively selected members participated in in-depth interviews based on their unhealthy food-purchasing and consumption patterns identified in the first phase. The third phase involved food price audits from supermarkets as well as convenient stores located in the study setting. Quantitative data were subjected to descriptive statistical analysis, while content analysis was used to analyze qualitative data. Most of the members were illiterate and unemployed, largely dependent on government grants. Qualitative findings showed that low household incomes, their inability to read and interpret nutritional information and personal food preferences contributed to Health club members' unhealthy food-purchasing behaviour. When objectively measured in local stores, the healthier food options proved to be more expensive than their less healthy equivalents. This was consistent with subjects' perceptions about the relative cost

    The total number of subjects was 2754 children (1354 boys and 1402 girls), who visited the Pedodontic Clinic of Kyushu University during the 5 year period from April 1st 1981 to March 31st 1986. We investigated the actual conditions of patients who complained of occlusal disharmony and who were ascertained to be associated with occlusal disharmony. The results were as follows: 1. The percentage ratio of patients with chief complaints concerning occlusions was 14.5% and the percentage of patients with various type of complaints as well as the problem of occlusion was 8.1%. The ratio of the sex of the patients who complained of their occlusal disharmony was 43.0% for boys and 57.0% for girls. 2. The age distributions of the patients who had as the chief complaint occlusal disharmony were at the ages of 3 and 6 to 7 at the maximum. 3. The number of patients who were diagnosed with occlusal disharmony at the first examination was 28.5%. These included anterior cross-bite 32.5%, edge to edge bite 14.1%, cross-bite 13.0%, crowding 11.8% and et al. 4. The distribution of anterior cross-bites due to the developmental stage was divided into the deciduous dentition 59.9%, the mixed dentition 39.3% and the permanent dentition 0.8%. 5. The sex ratios of anterior cross-bites in the deciduous dentition were 45.6% for boys and 54.4% for girls. 6. The treatment of occlusal guidance for anterior cross-bite in the deciduous dentition started from ages 3 to 5. 7. The appliances used for the treatment of anterior cross-bite in the deciduous dentition were maxillary protraction 25.0%, the chin cap 20.0%, the FKO 17.5%, and the lingual arch with herical springs 15.0% and et al. 8. The status of the patients with the anterior cross-bite in the deciduous dentition as of August 1986 was that the 36.2% was under the observation, and 24.4% was under the treatment of occlusal guidance or under the observation after the treatment was done.

  20. Evaluation of forensic medical history taking from the child in cases of child physical and sexual abuse and neglect.

    Suspected child physical abuse, sexual abuse and neglect are not uncommon presentations. As part of the assessment of these cases, a forensic medical history may be taken. This forensic history is used not only to determine the steps necessary to address the child's wellbeing but also to direct the forensic examination. Currently, there is no clear consensus on whether or not a forensic medical history should consistently be considered an integral element within the paediatric forensic evaluation. This study examines the value derived by the medical practitioner taking a forensic medical history rather than relying on hearsay evidence when a child presents for an assessment. A retrospective review of paediatric cases seen by the Victorian Forensic Paediatric Medical Service (VFPMS) between 2014 and 2015 was undertaken. 274 forensic case reports were reviewed and the data was entered into an Excel spread sheet and analysed using chi squared tests within STATA ® . With increasing age of the child, a forensic medical history is significantly more likely to be taken. Additional information is made available to the medical practitioner what would otherwise have been provided if the medical practitioner relied only on the interview conducted by the police. Discrepancies observed between the official third parties (police or child protection) report of what a child has said and what the child says to the medical practitioner decrease with age, as do discrepancies observed between the child's version of events and a third party's (eg. parents, caregivers, friends) version of events. The study showed that by taking a forensic medical history from the child additional information can be obtained. Further, that there is a value in the examining medical practitioner taking a forensic medical history from children in cases of child physical and sexual abuse and neglect.

    14 cattle (mainly younger ones) of a total of 50 extensively kept Galloways died within 6 weeks in late winter 2001/02. According to the owner's report, grass growth had been rather poor; therefore, the herd was fed additionally hay as well as large amounts of tulip onions. In the microbiological examination a highly reduced hygienic quality of the roughage could be detected. In the rumen contents of two dissected young cattle parts of tulip onions were found. According to pertinent literature, tulip onions (in particular their external layers) contain variant-specific amounts of anti-nutritive substances; main active agents are tulipin (a glycoprotein), tuliposid A and B, and lectins. They may cause intensive mucosal irritation, accompanied by reduced feed digestion and body-weight gains, drooling, vomiting and diarrhea. This case report underlines risks caused by feeding of plants originally not destined as forage, if their active ingredients and effects are unknown or remain unconsidered.

  6. Case history of natural analogue research on sandstone type uranium occurrences, Japan

    International Nuclear Information System (INIS)

    Sakamaki, Y.; Kanai, Y.

    1991-01-01

    Previous fundamental studies on the ore genesis of uranium occurrences chiefly in Cenozoic sandstone formations in Japan, have been re-examined as the case history on natural analogue of radionuclides in high-level radioactive wastes (HLRW). Two principal mode of occurrences have been distinguished among Cenozoic uranium localities in Japan. In the Setouchi (Inland Sea) subregion, hot-spots are found in lacustrine to shallow sea facies of calm environment, corresponding to the first stage of formation of tectonic basins. As observed in Ningyo-toge and Tono area, stratabound ore bodies are generally arranged into paleo-channels. Another type of sporadic uranium indications are found within collapse basins in the 'Green-tuff' subregion, where intense volcanisms and block movements had been taken places throughout Middle miocene age. Well-developed fractures were to be favorable paths for uraniferous groundwater, as well as the suitable site for deposition of uranium. In both cases, the source material of uranium is granitic basement. Under oxidizing environment, uranium anomalies have been occasionally detected in surface- or fracture waters which passing through decomposed granite. In contrast to the behavior of uranium, one of the adequate analogues for mobile nuclides, thorium and REE are relatively immobile even under the same geologic and geochemical circumstances. In ore horizon, where reducing condition has still been kept, geochronological age of tetravalent uranium mineral is in concordance with the age of the host rock. Analysis of structural control shows that the principal factors for uranium concentration are the layout of redox front related to paleo-water tables. 234U/238U disequilibrium method has been proved to be the powerful tool for detecting mobility of uranium in the host rock throughout diagenesis and weathering process. The result of field and laboratory works on this is reported as an example. (author)

    Controlling of landsides safely and economically is a great challenge to mine operators because landslides are major geological problems especially in open-pit mines. In this paper, a case history at Panluo open-pit mine is presented in detail to share the experiences and lessons with mine operators. Panluo open-pit mine is located in the southwestern Fujian province of China. It is the largest open-pit iron mine in the Fujian province and was planned in 1965 and is in full operation from 1978. In July 1990, an earthquake of magnitude 5.3 in Taiwan Strait and big rainstorms impacted the mine slope, causing tension cracks and rather large-scale failures, and forming a U-shaped landslide. Total potential volume was estimated to be up to 1.0 × 106 m3. This directly threatened the mine production. In order to protect the mine production and the dwellers’ safety around, a dynamic comprehensive method was implemented including geotechnical investigations, in-situ testing and monitoring, stability analysis, and many mitigation and preventive measures. These measures slowed down the development and further occurrence of the landslide. The results showed that the landslides were still active, it was slowed with the control measures and moved rapidly with rainfall and mining down. However, no catastrophic accidents occurred and the pit mining was continued till it was closed at the elevation of 887 m in 2000. As a successful case of landslide control at an open-pit mine for 10 years, this paper reports the controlling measures in details. These experiences of landslide control may be beneficial to other similar mines for landslide control.

    The basics of water conservation revolve around three R's of Reduce, Recycle, and Reuse. The Heavy Water Plants are an excellent example of water savings, and these case studies will be of interest to the chemical industry. The issues involved with water conservation and re-use in different Heavy Water Plants are of different nature. In H 2 S-H 2 O process plants the water consumption has been substantially decreased as compared to the design water needs. To quote the figures HWP (Kota) was designed to consume 2280 m 3 /hr water, which included 453 m 3 /hr water as feed for deuterium extraction. Today the plant operates with only 1250 m 3 /hr water while processing 500 m 3 /hr feed; and is headed to decrease the total water consumption to 700 m 3 /hr. Similarly at HWP (Manuguru) the design had provided 5600 m 3 /hr water consumption, which is today operating with only 1750 m 3 /hr and poised to operate with 1600 m 3 /hr. The issues of water conservation in Ammonia Hydrogen exchange plants have an additional dimension since water losses mean direct loss of heavy water production. In adjoining ammonia plants deuterium shifts to steam in the reformer and shift converter, and this excess steam is condensed as rich condensate. It becomes incumbent on the fertilizer plant to maintain a tight discipline for conserving and re-using the rich condensate so that deuterium concentration in the synthesis gas is maintained. Efforts are also underway to utilize rich condensate of GSFC in the newly developed technology of water ammonia exchange at HWP (Baroda) and we are targeting 20% production gains by implementation of this scheme and with no increase in the pollution load. These case histories will be of interest to Chemical Process Industry. (author)

    Cementation of in-situ combustion (ISC) wells is challenging since wells are frequently associated with weak and unconsolidated formation. However, cement rise up to surface is desired to prevent casing failure. Moreover, the cement sheath is also required to withstand extreme stresses due to high temperature cycling experienced during in-situ combustion process. In response to the problem of inadequate placement time and flash setting, Portland cement-silica blends were used for cementation of ISC wells in India instead of alumina cement blends. However, the use of the cement-silica blends has resulted in insufficient cement rise because of losses during cementation. The cured cement failed to contain the strength and permeability in course of ISC process causing charge of sub-surface shallower layers. This paper discussed the development and implementation of a non-alumina based thermally stable lightweight lead slurry and a ductile high temperature resistance tail slurry for mitigating these problems. The paper provided details of the study as well as four successful case histories. The cementing practice for ISC wells around the world was first described and illustrated. Next, the paper outlined the formulation of thermally stable tail slurry through laboratory studies. Slurry parameters of the tail slurry were presented, including slurry weight; thickening time; fluid loss; free fluid; and rheology. The paper also reviewed a study of compressive strength and permeability of thermal slurry; slurry parameters of the lightweight lead slurry; and study of compressive strength and permeability of lightweight thermal slurry. 8 refs., 4 tabs., 12 figs.

    Loo, W.W.; Wang, I.S.; Fan, J.

    1994-01-01

    This paper presents a case history on the bioventing of gasoline in soil with electrokinetic enhancement. The gasoline in soil was related to a 10,000-gallon underground storage tank spill, San Diego, California. The gasoline soil plume covers an area of about 2,400 square feet and to a depth of about 30 feet. The upper 15 feet of the soil plume consists of highly conductive marine clay. The lower 15 feet of the soil plume consists of dense cemented conglomerate sandstone. The gasoline concentration in the soil plume range from 100 to 2,200 mg/Kg(ppm) and the target cleanup level is below 100 ppm. Total gasoline in soil plume is estimated at about 1,000 pounds of gasoline in about 3,500 tons of soil. The soil remediation effort was completed after about 90 days of treatment. The concentration of gasoline in soil after treatment was way below the proposed cleanup level of less than 100 mg/Kg(ppm). The cost of treatment is about $50 per ton for this advanced soil treatment process which provides a cost effective solution to this soil plume with minimum disruption to business operation at the facility

  11. The role of risk assessment in remedial action cleanup programs (RACP): A case history

    1988-01-01

    A RACP (Remedial Action Cleanup Program) selects site cleanup criteria that protect human health and the environment and are cost effective. They generally use existing environmental standards and/or guidelines which include safe drinking water, RCRA groundwater protection, threshold limit values and air quality standards, and recommended soil cleanup level guidelines. If these are the only criteria used, the RACP may be more stringent and expensive than necessary. Another step, a risk assessment program, should then be considered in the cleanup decision process. A risk assessment uses chemical concentrations observed in soils, groundwater, and air to project their impact on human health and the environment. Toxicological data on human exposure to these concentrations (LD 50s and carcinogenic action levels) are used to assess risks to human health and the environment. The risk assessment also considers the probability of exposure. E.g., remedial programs at Superfund sites consider three criteria in order to assess risks to human health and the environment: (1) pathways of exposure, (2) population at risk, and (3) chemicals of concern. By eliminating or severely limiting the significance of any criteria, the site may no longer represent a significant risk. This paper presents a RACP case history where a risk assessment was needed to select a cost effective and environmentally acceptable cleanup program

  12. Geomechanics in hard rock mining-Lessons from two case histories

    This paper summarizes the geomechanics programs conducted in two hard rock underground mining operations in the Western United States, between 1966 and 1981. The two projects were directed towards understanding the behavior of the rock masses, at the scale of the caverns. To this end, the emphasis was put on large scale field measurements, complemented by limited laboratory testing. The results of these observations were used to build realistic finite element models of the underground chambers. In the marble mine, at Crestmore, California, the models were applied to the structural optimization of the room-and-pillar pattern. In the granite mining, at Climax, Nevada Test Site, the models explained some unusual stress changes observed during excavation. Based on the large number of geomechanical techniques employed, specific conclusions and recommendations are offered regarding the quality, applicability, and usefulness of the various methods. The two case histories clearly indicate that numerical models are extremely useful for a detailed understanding of the structural behavior of mine openings. To be realistic, these models must be based first and foremost on large scale field observations. The lessons learned on these two projects also are directly applicable to the design and analysis of nuclear waste repositories in hard rocks such as basalt, granite, and welded tuff

    2015-09-01

    This paper presents a historical and conceptual analysis of a group of research strategies known as the Single-Case Methods (SCMs). First, we present an overview of the SCMs, their history, and their major proponents. We will argue that the philosophical roots of SCMs can be found in the ideas of authors who recognized the importance of understanding both the generality and individuality of psychological functioning. Second, we will discuss the influence that the natural sciences' attitude toward measurement and experimentation has had on SCMs. Although this influence can be traced back to the early days of experimental psychology, during which incipient forms of SCMs appeared, SCMs reached full development during the subsequent advent of Behavior Analysis (BA). Third, we will show that despite the success of SCMs in BA and other (mainly applied) disciplines, these designs are currently not prominent in psychology. More importantly, they have been neglected as a possible alternative to one of the mainstream approaches in psychology, the Null Hypothesis Significance Testing (NHST), despite serious controversies about the limitations of this prevailing method. Our thesis throughout this section will be that SCMs should be considered as an alternative to NHST because many of the recommendations for improving the use of significance testing (Wilkinson & the TFSI, 1999) are main characteristics of SCMs. The paper finishes with a discussion of a number of the possible reasons why SCMs have been neglected.

    Fragrances are the first or second most common cause of contact allergy in dermatitis patients. The aim of this study was to identify risk products for fragrance contact allergy. The design was a case-control study with a case group of 78 fragrance-mix-positive eczema patients and two control groups, one consisting of 1,279 subjects selected as a random sample of the general population and the other consisting of 806 fragrance-mix-negative eczema patients. The identification of risk products was based on the patients' histories of rash to scented products. Analysis of the associations between first-time rash caused by different specified product categories and fragrance mix sensitivity was performed using logistic regression. It was found that first-time rash caused by deodorant sprays and/or perfumes were related to fragrance contact allergy in a comparison with both control groups. The risk (odds ratio) of being diagnosed as fragrance allergic was 2.3 to 2.9 greater in cases of a history of first-time rash to deodorant sprays and 3.3 to 3.4 greater in cases of a history of rash to perfumes than if no such history were present. First-time rash to cleansing agents, deodorant sticks, or hand lotions was also statistically significant but only in comparison with one of the control groups. Safety evaluation of fragrance materials used in perfumes and deodorant sprays should be performed with special attention.

    The incidence of melanoma in Denmark has immensely increased over the last 10 years making Denmark a high risk country for melanoma. In the last two decades multiple public campaigns have sought to increase the awareness of melanoma. Family history of melanoma is a known major risk factor...... but previous studies have shown that self-reported family history of melanoma is highly inaccurate. These studies are 15 years old and we wanted to examine if a higher awareness of melanoma has increased the accuracy of self-reported family history of melanoma.

    Full Text Available Antrax is an acute infectious disease, characterised by heavy intoxication, specific pustules both on skin and mucosa, accompanied by edema or appearance of haemorrhagic inflammatory pulmonary and intestinal changes, and in the most severe cases by septicaemia. Antrax is spread worldwide, especially in countries with developed cattle raising. The main cause of this disease is Bacillus Anthracis, gram positive bacteria very resistent in outside enviroment, especially its sporogenic form witch can survive from 30 to 50 years. Antrax bacillus secrets three toxins (edema toxin, protective toxin and lethal toxin. For the appearance of this disease the associated effect of all three factors is necessary. The aim of our research is to present the skin form of antrax, complicated by secundary intrahospital infection.

  2. Seismic response in archaeological areas: the case-histories of Rome

    Science.gov (United States)

    Donati, Stefano; Funiciello, Renato; Rovelli, Antonio

    1999-03-01

    Rome is affected by earthquakes associated to three different seismogenic districts: the Central Apennines area, the Colli Albani volcanic area and the Roman area. The major effects were exclusively due to Apennine seismicity and reached in some cases felt intensities up to VII-VIII degree (MCS scale). The predominant role in the damage distribution seems to be played by the local geological conditions. The historical centre of the city is characterized by the presence of two geomorphologic domains: the alluvial plain of Tiber river and the topographic relieves of Roman Hills, where tradition indicates the first site of the city foundation. In particular, the right river side is characterized by the outcropping of the regional bedrock along the Monte Mario-Gianicolo ridge, while the eastern relieves are the remnants of the Sabatini and Albani volcanic plateau, deeply eroded by the Tiber river and its tributaries during the last glacial low-stand (Würm). These domains are characterized by a large difference in seismic response, due to the high impedance contrast between Holocene coarse deposits filling the Tiber Valley and sedimentary and volcanic Plio-Pleistocene units. Seismic damage observed in 150 monuments of downtown Rome was indicating a significant concentration on alluvial recent deposits. This result was confirmed by the geographical distribution of conservation and retrofitting activities subsequent to main earthquakes, mostly related to local geological conditions. The cases of Marcus Aurelius' Column and Colosseum confirmed the influence of the Holocene alluvial network in local seismic response. During 2500 years of history, the monuments of Rome have `memorized' the seismic effects of historical earthquakes. In some cases, the integration of historical and geological research and macroseismic observations may provide original and useful indications to seismologists to define the seismic response of the city. Local site effects represent a serious

    We evaluated the association between a history of sexually transmitted diseases (STDs) and the risk for prostate cancer (PC) among Mexican males. PC incident cases (n=402) that were identified at six public hospitals in Mexico City were matched by age (±5 years) with 805 population controls with no history of PC. By face-to-face interview, we obtained information about sexual history, previous STDs, sociodemographic characteristics, and familial history of PC. An unconditional logistic regression model was used to estimate the risk for PC. A total of 16.6% of men reported having had at least one previous STD, and the most frequently reported STD was gonorrhea (10.5%). After adjusting by PC familial history, the history of STD was associated with a two-fold greater risk of PC: odds ratio (OR)=2.67; 95% confidence interval (95% CI=1.91-3.73). When each STD was evaluated separately, only gonorrhea was associated with a significant increase in PC risk (OR=3.04; 95% CI=1.99-4.64). These associations were similar when we stratified by low-risk PC (Gleason <7) and high-risk PC (Gleason ≥7). These results confirm that STDs, and particularly gonorrhea, may play an etiological role in PC among Mexican males, which is consistent with a previous report from a multiethnic cohort.

  9. Investigation of Nonlinear Site Response and Seismic Compression from Case History Analysis and Laboratory Testing

    Science.gov (United States)

    Yee, Eric

    In this thesis I address a series of issues related to ground failure and ground motions during earthquakes. A major component is the evaluation of cyclic volumetric strain behavior of unsaturated soils, more commonly known as seismic compression, from advanced laboratory testing. Another major component is the application of nonlinear and equivalent linear ground response analyses to large-strain problems involving highly nonlinear dynamic soil behavior. These two components are merged in the analysis of a truly unique and crucial field case history of nonlinear site response and seismic compression. My first topic concerns dynamic soil testing for relatively small strain dynamic soil properties such as threshold strains, gammatv. Such testing is often conducted using specialized devices such as dual-specimen simple-shear, as devices configured for large strain testing produce noisy signals in the small strain range. Working with a simple shear device originally developed for large-strain testing, I extend its low-strain capabilities by characterizing noisy signals and utilizing several statistical methods to extract meaningful responses in the small strain range. I utilize linear regression of a transformed variable to estimate the cyclic shear strain from a noisy signal and the confidence interval on its amplitude. I utilize Kernel regression with the Nadaraya-Watson estimator and a Gaussian kernel to evaluate vertical strain response. A practical utilization of these techniques is illustrated by evaluating threshold shear strains for volume change with a procedure that takes into account uncertainties in the measured shear and vertical strains. My second topic concerns the seismic compression characteristics of non-plastic and low-plasticity silty sands with varying fines content (10 ≤ FC ≤ 60%). Simple shear testing was performed on various sand-fines mixtures at a range of modified Proctor relative compaction levels ( RC) and degrees-of-saturation (S

  10. Case histories of microbiologically influenced corrosion of austenitic stainless steel weldments

    International Nuclear Information System (INIS)

    1990-01-01

    Microbiologically influenced corrosion (MIC) is initiated or accelerated by microorganisms and is currently recognized as a serious problem affecting the construction and operation of many industrial facilities, including nuclear power plants. The purpose of this paper is to review how biofouling and MIC can occur and discuss current mechanistic theories. A case history of MIC attack in power plants is examined with emphasis on the role of welding and heat treatment variables using laboratory electrochemical analyses. Although MIC can occur on a variety of alloys, pitting corrosion failures of austenitic stainless steels are often associated with weldments. MIC occurs as the result of a consortium of microorganisms colonizing on the metal surface and their variety (fungi, bacteria, algae, mold, and slimes) enables them to form support systems for cross feeding to enhance survival. The metabolic processes influence corrosion behaviour of materials by destroying protective coatings, producing a localized acid environment, creating corrosive deposits, or altering anodic and cathodic reactions. On stainless steels, biofilms destroy the passive oxide film on the surface of the steels and subject them to localized forms of corrosion. Many of the MIC failures in industry result in pitting to austenitic stainless steel weldments. Pitting primarily occurs in the weld metal, heat affected zones, and adjacent to the weld in the base metal. Depending on the conditions of the concentration cell created by the biofilm, either phase of the two-phase duplex stainless steel, austenite or delta ferrite, may be selectively attacked. Theories have been proposed about the mechanism of MIC on austenitic stainless steel and and a general understanding is that some function associated with the biofilm formation directly affects the electrochemical process

    This paper focuses on a study aimed at defining the role of geological-structural setting and Quaternary morpho-structural evolution on the onset and development of a deep-seated gravitational slope deformation which affects the western slope of Mt. Genzana ridge (Central Apennines, Italy). This case history is particularly significant as it comprises several aspects of such gravitational processes both in general terms and with particular reference to the Apennines. In fact: i) the morpho-structural setting is representative of widespread conditions in Central Apennines; ii) the deforming slope partially evolved in a large rockslide-avalanche; iii) the deformational process provides evidence of an ongoing state of activity; iv) the rockslide-avalanche debris formed a stable natural dam, thus implying significant variations in the morphologic, hydraulic and hydrogeological setting; v) the gravitational deformation as well as the rockslide-avalanche reveal a strong structural control. The main study activities were addressed to define a detailed geological model of the gravity-driven process, by means of geological, structural, geomorphological and geomechanical surveys. As a result, a robust hypothesis about the kinematics of the process was possible, with particular reference to the identification of geological-structural constraints. The process, in fact, involves a specific section of the slope exactly where a dextral transtensional structure is present, thus implying local structural conditions that favor sliding processes: the rock mass is intensively jointed by high angle discontinuity sets and the bedding attitude is quite parallel to the slope angle. Within this frame the gravitational process can be classified as a structurally constrained translational slide, locally evolved into a rockslide-avalanche. The activation of such a deformation can be in its turn related to the Quaternary morphological evolution of the area, which was affected by a significant

    This case history discusses the exploration methods used at the Momotombo Geothermal Field in western Nicaragua, and evaluates their contributions to the development of the geothermal field models. Subsequent reservoir engineering has not been synthesized or evaluated. A geothermal exploration program was started in Nicaragua in 1966 to discover and delineate potential geothermal reservoirs in western Nicaragua. Exploration began at the Momotombo field in 1970 using geological, geochemical, and geophysical methods. A regional study of thermal manifestations was undertaken and the area on the southern flank of Volcan Momotombo was chosen for more detailed investigation. Subsequent exploration by various consultants produced a number of geotechnical reports on the geology, geophysics, and geochemistry of the field as well as describing production well drilling. Geological investigations at Momotombo included photogeology, field mapping, binocular microscope examination of cuttings, and drillhole correlations. Among the geophysical techniques used to investigate the field sub-structure were: Schlumberger and electromagnetic soundings, dipole mapping and audio-magnetotelluric surveys, gravity and magnetic measurements, frequency domain soundings, self-potential surveys, and subsurface temperature determinations. The geochemical program analyzed the thermal fluids of the surface and in the wells. This report presents the description and results of exploration methods used during the investigative stages of the Momotombo Geothermal Field. A conceptual model of the geothermal field was drawn from the information available at each exploration phase. The exploration methods have been evaluated with respect to their contributions to the understanding of the field and their utilization in planning further development. Our principal finding is that data developed at each stage were not sufficiently integrated to guide further work at the field, causing inefficient use of

    Though the etiology is largely unknown, testicular cancer incidence has seen recent significant increases in northern Europe and throughout many Western regions. The most common cancer in males under age 40, age period cohort models have posited exposures in the in utero environment or in early childhood as possible causes of increased risk of testicular cancer. Some of these factors may be tied to geography through being associated with behavioral, cultural, sociodemographic or built environment characteristics. If so, this could result in detectable geographic clusters of cases that could lead to hypotheses regarding environmental targets for intervention. Given a latency period between exposure to an environmental carcinogen and testicular cancer diagnosis, mobility histories are beneficial for spatial cluster analyses. Nearest-neighbor based Q-statistics allow for the incorporation of changes in residency in spatial disease cluster detection. Using these methods, a space-time cluster analysis was conducted on a population-wide case-control population selected from the Danish Cancer Registry with mobility histories since 1971 extracted from the Danish Civil Registration System. Cases (N=3297) were diagnosed between 1991 and 2003, and two sets of controls (N=3297 for each set) matched on sex and date of birth were included in the study. We also examined spatial patterns in maternal residential history for those cases and controls born in 1971 or later (N= 589 case-control pairs). Several small clusters were detected when aligning individuals by year prior to diagnosis, age at diagnosis and calendar year of diagnosis. However, the largest of these clusters contained only 2 statistically significant individuals at their center, and were not replicated in SaTScan spatial-only analyses which are less susceptible to multiple testing bias. We found little evidence of local clusters in residential histories of testicular cancer cases in this Danish population. PMID

    Full Text Available According to the new and previously known documents it is concluded the earthquake of Chile in 1730 was composed by two independent earthquakes, each associated to a tsunami. Considering the latitudinal extension of the damage and the size of the tsunamis, it can be taken as the largest seismic event occurred in the history of Metropolitan or Central Chile. These conclusions allow to know better the seismic sequence of Central Chile, the Seismic History of the country, and contribute to the knowledge of the colonial history of the kingdom of Chile.

Transcription errors from source documents to case report forms (CRFs) are common, and subsequently the errors pass from the CRFs to the electronic database. This study aimed to demonstrate the usefulness and to evaluate the effectiveness of mobile phone camera applications in capturing health-related data, aiming for data quality and completeness as compared to current routine practices exercised by government officials. In this study, the concept of "data entry via phone image capture" (DEPIC) was introduced and developed to capture data directly from source documents. This case study was based on immunization history data recorded in a mother and child health (MCH) logbook. The MCH logbooks (kept by parents) were updated whenever parents brought their children to health care facilities for immunization. Traditionally, health providers are supposed to key in duplicate information of the immunization history of each child; both on the MCH logbook, which is returned to the parents, and on the individual immunization history card, which is kept at the health care unit to be subsequently entered into the electronic health care information system (HCIS). In this study, DEPIC utilized the photographic functionality of mobile phones to capture images of all immunization-history records on logbook pages and to transcribe these records directly into the database using a data-entry screen corresponding to logbook data records. DEPIC data were then compared with HCIS data-points for quality, completeness, and consistency. As a proof-of-concept, DEPIC captured immunization history records of 363 ethnic children living in remote areas from their MCH logbooks. Comparison of the 2 databases, DEPIC versus HCIS, revealed differences in the percentage of completeness and

    Full Text Available A 7-month-old, entire female, domestic shorthair cat was referred to our behavioural service owing to soiling in the house and a play-related problem. The owners’ complaints were that the cat had never used the litter tray, and it did not know how to play. After reviewing the behavioural history, a problem of substrate preferences acquisition was suspected with regard to the elimination problem. During the consultation, the physical examination was unremarkable, but the neurological examination revealed a moderate and hypermetric ataxic gait, and a bilateral lack of menace response. Some degree of visual impairment was suspected. The problem was located in the central nervous system (CNS; specifically, an intracranial and multifocal problem was diagnosed. After a complete work-up (complete ophthalmological examination, complete blood count and a complete biochemistry panel, feline immunodeficiency virus/feline leukaemia virus test, thorax radiographs, abdominal ultrasound, brain magnetic resonance imaging [0.2 T], cerebrospinal fluid analysis and a urinary metabolic screen test, a degenerative CNS problem was suspected. No treatment was prescribed for the neurological problem. Regarding the problem of soiling in the house, reward-based training with a clicker was used, and the cat partially improved in a few weeks. Three months later, the cat was referred to the neurology service in status epilepticus. A symptomatic treatment was prescribed, with a mild response. After 2 years of treatment and a progressive worsening, the cat was euthanased. Necropsy revealed spongiform polioencephalomyelopathy. In order to rule out prion aetiology a PrPsc inmunohistochemistry assay was performed, and the results were negative. Congenital spongiform polioencephalomyelopathy (CSP was diagnosed. We strongly suggest that the cat’s behavioural clinical signs were caused by the CSP, causing learning impairment. To the best of our knowledge, this would be the

    Full Text Available AbstractThe didactics of history and the content of the curriculum and syllabi have changed over the years in order to make history more relevant for the students of today. It is important to provide students with “knowing what” knowledge in addition to “knowing how” knowledge in order to support and develop critical thinking and historical understanding. One way of promoting historical understanding is through introducing the concepts of historical thinking. However, studies show that history classes often promote teaching that is still quite traditional, using history books uncritically and without problematizing their truthfulness, which do not make students see how history is formed, nor how it can be important for the present and the future. The present article explores whether the concepts of historical thinking are encouraged and used in three different lower secondary schools in Norway today. The main sources of data are current history textbooks, teaching plans, tests and assignments. The findings of the study show that the concepts of historical thinking are not made clear and explicit enough in neither history books, plans nor tests. Furthermore, it seems like reproduction rather than reflection is focused on in many classrooms, making it difficult to develop a historical understanding. It is therefore suggested that both teachers and students learn and work thoroughly with the concepts of historical thinking.schools in Norway today. History books in use, plans, tests and assignments were considered important empirical information for the research question. The findings of the study show that the concepts of historical thinking are not clear enough neither in history books, plans nor tests. Furthermore, it seems like reproduction rather than reflections are practiced in many classrooms, making it difficult to get a historical understanding.

    A healthy 72-year-old Danish male presenting with recurring sigmoid volvulus was found to be infested with Schistosoma mansoni . No other explanation for recurring volvulus was found. A travel history 12 years ago, which included bathing in the Botswana Okavango delta for 10 minutes, revealed the likely time and place of infection. To our knowledge, this is the first reported case of recurrent sigmoid volvulus and chronic intestinal schistosomiasis in a patient from a nonendemic area.

    Skin testing in duplicate, correlation between case history of immediate and nonimmediate reactions and challenge outcome and prolonged oral treatment with penicillin in the diagnostic evaluation of allergic reactions to β-lactam antibiotics, mimicking real-life situations, have only been addressed in few studies. A total of 342 patients suspected of having β-lactam allergy were investigated according to the European Network for Drug Allergy (ENDA) guidelines and patients found to be negative in the ENDA program were supplemented with a 7-day oral treatment with penicillin. Skin testing with penicillins was performed in duplicate. Patients with case histories of reactions to other β-lactams were also subsequently challenged with the culprit drug. Nineteen patients were IgE-sensitized to penicillin. Then, intracutaneous tests (ICTs) were performed, in which 35 patients tested positive for allergy, 21 with delayed and 14 with immediate reactions. Only three patients tested positive for the major (PPL) and/or minor (MDM) penicillin determinants, all being positive for penicillin G in ICT. The remaining 291 patients were challenged with penicillin: 10 tested positive in single-dose challenge and 23 tested positive in the 7-day challenge. A total of 17 of 78 patients with a negative penicillin challenge tested positive during challenges with other β-lactams. We found no correlation between case histories of immediate and nonimmediate reactions and reaction time during challenge. The data suggest that case history is often insufficient to discriminate between immediate reactors and nonimmediate reactors. A 7-day challenge with the culprit β-lactam may yield more positive reactions than the accepted one- or 2-day challenge. Interpretation of skin testing should be made with caution. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Full-arch rehabilitation of patients with severe tooth wear due to parafunctional behavior is a challenge for dentists and dental technicians, especially when a highly esthetic outcome is desired. A variety of different treatment options and prosthetic materials are available for such a clinical undertaking. The ongoing progress of computer-aided design/computer-assisted manufacture technologies in combination with all-ceramic materials provides a predictable workflow for these complex cases. This case history report describes a comprehensive, step-by-step treatment protocol leading to an optimally predictable treatment outcome for an esthetically compromised patient.

  8. Structuring knowledge on Romanian communism: the case of the oral history interview

    Directory of Open Access Journals (Sweden)

    Diana PAINCA

    2017-11-01

    Full Text Available The present paper offers a comprehensive analysis of the way in which the oral history interview can organize knowledge about communism in Romania. The data are retrieved from the book Memorialul Durerii: Întuneric şi lumină (2013 compiled by author Iulia Hossu Longin from dozens of oral history interviews with survivors of communism. As the examination demonstrates, the first element commanding attention is memory. Hence, oral history shifts the focus from memory as object to memory as subject, or as a source of investigation per se. Secondly, the analysis reveals how the extensive use of lists structures knowledge about Romanian communism in an intelligible and insightful way. These lists not only provide a window on the communist experience but they also bring the individual -fighting against the regime - into the foreground.

    Full Text Available This article aims to outline an epistemological framework for placing the field of environmental history in the context of the current endeavor of social sciences and humanities. The methodology used is defined here as “metabolic landmarks” because it is inspired by the approach of social metabolism. The results suggest that, in the study of environmental history, the specific historiographical object plays an essential role in defining the epistemic context of that hybrid field of historiography and, more generally, of social and environmental analyses.

  10. The actual goals of geoethics

    2014-05-01

    The most actual goals of geoethics have been formulated as results of the International Conference on Geoethics (October 2013) held at the geoethics birth-place Pribram (Czech Republic): In the sphere of education and public enlightenment an appropriate needed minimum know how of Earth sciences should be intensively promoted together with cultivating ethical way of thinking and acting for the sustainable well-being of the society. The actual activities of the Intergovernmental Panel of Climate Changes are not sustainable with the existing knowledge of the Earth sciences (as presented in the results of the 33rd and 34th International Geological Congresses). This knowledge should be incorporated into any further work of the IPCC. In the sphere of legislation in a large international co-operation following steps are needed: - to re-formulate the term of a "false alarm" and its legal consequences, - to demand very consequently the needed evaluation of existing risks, - to solve problems of rights of individuals and minorities in cases of the optimum use of mineral resources and of the optimum protection of the local population against emergency dangers and disasters; common good (well-being) must be considered as the priority when solving ethical dilemmas. The precaution principle should be applied in any decision making process. Earth scientists presenting their expert opinions are not exempted from civil, administrative or even criminal liabilities. Details must be established by national law and jurisprudence. The well known case of the L'Aquila earthquake (2009) should serve as a serious warning because of the proven misuse of geoethics for protecting top Italian seismologists responsible and sentenced for their inadequate superficial behaviour causing lot of human victims. Another recent scandal with the Himalayan fossil fraud will be also documented. A support is needed for any effort to analyze and to disclose the problems of the deformation of the contemporary

    Dancers are highly susceptible to musculoskeletal injuries and frequently require interaction with medical professionals. While many dancers have a finely tuned awareness of their bodies, their knowledge of the fundamentals of human anatomy is not uniform. There is a paucity of literature on the benefits of human anatomy education in dancers, though it seems intuitive that there should be a relationship. The purpose of this study was to assess dancers' perceived and actual knowledge of basic musculoskeletal anatomy and its relationship to function. Adult dancers at the undergraduate, pre-professional, and professional levels were surveyed through an anonymous online questionnaire. Questions included demographic information, dance techniques studied, anatomy training, and injury history. Subjects rated their perceived knowledge of anatomy and were tested with 15 multiple-choice questions on basic musculoskeletal anatomy. Four hundred seventy-five surveys were completed. Ordinal regression showed a correlation of perceived to actual knowledge of anatomy (p < 0.001). Factors that correlated with increases in both perceived and actual knowledge of anatomy included having taken an anatomy course of any type (p < 0.001) and increased age (p ≤ 0.001). Years of dance training and professional dancer status both significantly correlated with increased knowledge of anatomy (p < 0.001) but not perceived knowledge. Chi-square analysis showed that dancers with training in either modern or jazz dance had a significantly higher perceived, but not actual, knowledge when compared to those without training in those styles of dance (p < 0.001 and p = 0.011, respectively). In conclusion, dancers generally scored well on questions pertaining to basic musculoskeletal anatomy, and their perception correlated with their actual knowledge of anatomy. Factors that contribute to dancers' knowledge of anatomy include age, years of experience, professional dancer status, and anatomy training.

    Lowman, Paul D., Jr.; Smith, David E. (Technical Monitor)

    2002-01-01

    Having judged dozens of science fairs over the years, I am repeatedly disturbed by the ground rules under which students must prepare their entries. They are almost invariably required to follow the "scientific method," involving formulating a hypothesis, a test of the hypothesis, and then a project in which this test is carried out. As a research scientist for over 40 years, I consider this approach to science fairs fundamentally unsound. It is not only too restrictive, but actually avoids the most important (and difficult) part of scientific research: recognizing a scientific problem in the first place. A well-known example is one of the problems that, by his own account, stimulated Einstein's theory of special relativity: the obvious fact that when an electric current is induced in a conductor by a magnetic field , it makes no difference whether the field or the conductor is actually (so to speak) moving. There is in other words no such thing as absolute motion. Physics was transformed by Einstein's recognition of a problem. Most competent scientists can solve problems after they have been recognized and a hypothesis properly formulated, but the ability to find problems in the first Place is much rarer. Getting down to specifics, the "scientific method" under which almost all students must operate is actually the experimental method, involving controlled variables, one of which, ideally, is changed at a time. However, there is another type of science that can be called observational science. As it happens, almost all the space research I have carried out since 1959 has been this type, not experimental science.

    Full Text Available Abstract: Researcing of history of small advanced countries of Western Europe has a number of specific features, which are connected to its socio-economic level and dynamic development and the dependence on the external economic factor. So the article is devoted to the analysis of regularity of the development of the industry of Norwegian economic specialization (energy sector in the international division of labour as an important element of its historical development. The author of the article analyzes the influence of the energy sector on the political life of the country, the balance of political forces, legislation, foreign policy priorities, and the history of the development of society. At the same time he uses the interdisciplinary approach to determine the relationship of cause and effect between historical events to compile a complete historical picture. The author concludes that the regularities in history are universal and concern all small highly developed countries of Western Europe including Norway. The complex of economic, social, political, financial, legal, tax, environmental and other measures of state support to specialized branches of the national economy is the main semantic rod of historical events in many of the small countries of Western Europe. Analysis of individual industries of the economy in the international division of labor should be an integral part of researches of the historical development of small countries which have a narrow structure of economy, because it helps to understand the peculiarities of the historical development of nations.

This paper provides an in-depth description and analysis of how four social science and history elementary school teachers and their 70 students (5th–7th grades worked together between November 2011 and December 2012. Previous research regarding the use of information and communication technology (ICT in history education in elementary schools is limited, thus calling for contemporary investigations in this particular subject domain. The Technological Pedagogical Content Knowledge (TPACK model, enhancing the combination of teachers’ pedagogical, content and technical competence, was used as the analytical framework, together with nation-specific curricula and the European Union’s recommendations regarding students’ skills for lifelong learning. A range of empirical materials was analyzed, such as classroom observations, students’ video productions, texts and photos distributed and shared on a mutual blog, real-time interaction and teachers’ communication. The teachers tried out two ICT didactic models. In the asynchronous model, the major focus was on the form and content of the video productions being shared, whereas work with the synchronous model concentrated on the content and quality of the communication. Notwithstanding obstacles, cross-border collaboration provided added value. The nation-specific differences triggered curiosity and motivation to produce digital presentations of history content to be understood by the students in the three nations, facilitating goal fulfillment in communication skills and digital competence.

  5. The case history of the first pipeline installed in the Arctic and subsequent developments

    International Nuclear Information System (INIS)

    Brown, R.J.

    1990-01-01

    Large reserves of gas and oil have been discovered in Arctic areas which have led various companies to initiate research and development in ways to produce and transport these resources to market. The primary mode of transportation is by pipelines. The main problem is that these areas are remote and transportation systems are long and expensive, especially when considering conventional methods of pipeline construction. The reserves in Canada's Arctic areas are large but, at this time, gas cannot be delivered to market at prices competitive with other gas supplies being completed. This, however, is changing as gas and oil reserves in the lower Arctic have increased, and the combining of a transportation system for both, improves the economics for their development. This paper discusses some of the initial works which have been completed to the stage of an actual pipeline installation, and the planned techniques envisioned for future field developments and for long distance transmission systems

    2015-09-01

    Full Text Available Background Several factors have been reported as risk factors for multiple sclerosis (MS; however, the main causes of the disease are still unknown. A geographical area with a low MS incidence is Ahvaz, Iran. Objectives The objective of this study was to evaluate the association of several demographic characteristics, family history, and birth month with MS in Ahvaz. Patients and Methods This was a case-control study including 155 MS cases and 155 controls matched for age, sex, and residential status. The participants were selected randomly, using a systematic method, from the MS patients referred to the MS Society of Khuzestan (Iran. The data collection tool was a standardized questionnaire designed by the authors to assess demographic characteristics. Data were analyzed using descriptive statistics including mean, frequency, and standard deviation and inferential statistical tests including χ2, Fisher’s exact test, and logistic regression using SPSS version 19. Results In both cases and controls, no significant associations were found between Arab ethnicity and incidence of MS, marital status and risk of MS in Ahvaz, or more than 15-year residency in Ahvaz, birth in Khuzestan, and month of birth and the risk of MS (P > 0.05. However, there was a marginally significant association between living from birth to age 15 years in Ahvaz and MS (P = 0.05. Furthermore, there was an association between a family history of MS and the risk of MS in Ahvaz (P = 0.02, which was significant in univariate logistic regression (P = 0.006. Conclusions The findings suggested that according to the ecological conditions of Ahvaz, a family history of MS may increase the risk of developing MS.

    2016-05-01

    The aim was to describe sickness allowance histories before disability retirement due to mental disorders and to examine whether receiving sickness allowance due to mental disorders and somatic conditions predicts future disability retirement. Pre-retirement sickness allowance histories were traced backwards for 7 years among Finnish residents aged 25-64 years who had retired due to mental disorders in 2011 (n=5.544). For each retiree, five sex- and age-matched controls were drawn from the non-retired population. Conditional logistic regression was used to calculate the risk for disability retirement by sickness allowance history and to control for the effects of educational level, social class, marital status and the urbanisation level of the municipality. The proportion of sickness allowance recipients increased steadily during the years preceding disability retirement, and was highest among those who retired due to bipolar disorders or depression. Those who had received sickness allowance due to mental disorders 6-7 years earlier had 6.5 times higher risk and those with sickness allowance 1-2 years earlier 11.7 times higher risk for disability retirement. Sickness allowance due to somatic conditions increased the risk for disability retirement 1.6-1.9 times. Sickness allowance most strongly predicted retirement due to bipolar disorders and depression. Adjustment for covariates had little effect. Those who retired due to mental disorders more often had sickness allowance due to both mental disorders and somatic conditions, but in particular sickness allowance due to mental disorders predicted disability retirement due to mental disorders. © 2015 the Nordic Societies of Public Health.

Historical data indicate that root colour has been differentially selected over time and according to geographical areas. Root pigmentation depends on the relative proportion of different carotenoids for the white, yellow, orange and red types but only internally for the purple one. The genetic control for root carotenoid content might be partially associated with carotenoid biosynthetic genes. Carotenoid isomerase (CRTISO has emerged as a regulatory step in the carotenoid biosynthesis pathway and could be a good candidate to show how a metabolic pathway gene reflects a species genetic history.In this study, the nucleotide polymorphism and the linkage disequilibrium among the complete CRTISO sequence, and the deviation from neutral expectation were analysed by considering population subdivision revealed with 17 microsatellite markers. A sample of 39 accessions, which represented different geographical origins and root colours, was used. Cultivated carrot was divided into two genetic groups: one from Middle East and Asia (Eastern group, and another one mainly from Europe (Western group. The Western and Eastern genetic groups were suggested to be differentially affected by selection: a signature of balancing selection was detected within the first group whereas the second one showed no selection. A focus on orange-rooted carrots revealed that cultivars cultivated in Asia were mainly assigned to the Western group but showed CRTISO haplotypes common to Eastern carrots.The carotenoid pathway CRTISO gene data proved to be complementary to neutral markers in order to bring critical insight in the cultivated carrot history. We confirmed the occurrence of two migration events since domestication. Our results showed a European background in material from Japan and Central Asia. While confirming the introduction of European carrots in Japanese resources, the history of Central Asia

  9. Rethinking the early history of post-Vygotskian psychology: the case of the Kharkov school.

    2008-05-01

    Between the death of Vygotsky in 1934 and the discovery of Vygotsky's work in the West in 1962, Vygotskian psychology was developed through research done by the first generation of Vygotsky's students and their followers, primarily associated with the Kharkov School. Surprisingly, these studies carried out in the 1930s, of great importance for the development of virtually all subsequent Vygotskian psychology, still remain largely unknown; this represents a significant gap in understanding the history of Vygotskian psychology as an empirical study of consciousness. This paper provides a systematic overview of the research agenda of the Kharkov group between 1931 and 1941 and provides new insights into the early development of Vygotskian psychology.

  10. An Autopsy Case of Fulminant Amebic Colitis in a Patient with a History of Rheumatoid Arthritis

    Full Text Available Generally, amebic colitis is localized around the mucosal membrane and often accompanied by diarrhea and abdominal pain. We describe a patient with a history of rheumatoid arthritis who had received prolonged steroid therapy. The patient complained of breathing difficulties because of rheumatoid lung disease. Although the patient was given antibacterial agent, the symptoms did not improve until death. We did an autopsy and found that he had fulminant amebic colitis, although the patient was not previously examined. Histochemical analysis revealed severe inflammation and full-thickness necrosis of the colon by ameba, suggesting the involvement of ameba in the progression of the overall condition.

    Exploration for radioactive mineralizations and mineral accumulations in Egypt during the last five years involved the application of new techniques and their adaptation to the prevailing semi-arid to arid environment. The mobilization of uranium and thorium, and their daughter products in the oxidation zone, is greatly influenced by this particular environment. Exploration techniques employed include the use of airborne, space-borne, ground and sub-surface methodologies. Case histories for uranium exploration have been formulated through practical experience, which can be applied in the arid regions in different parts of the world where conditions are comparable to those of Egypt.

    Onset during old age has been reported in upto 10% of total cases of inflammatory bowel disease (IBD). To evaluate phenotypic characteristics and the use of therapeutic resources in patients with elderly onset IBD. Case-control study including all those patients diagnosed with IBD over the age of 60 years since 2000 who were followed-up for >12 months, identified from the IBD databases. Elderly onset cases were compared with IBD patients aged 18 to 40 years at diagnosis, matched by year of diagnosis, gender and type of IBD (adult-onset). One thousand three hundred and seventy-four elderly onset and 1374 adult-onset cases were included (62% ulcerative colitis (UC), 38% Crohn's disease (CD)). Among UC patients, elderly onset cases had a lower proportion of extensive disease (33% vs 39%; P < 0.0001). In CD, elderly onset cases showed an increased rate of stenosing pattern (24% vs 13%; P < 0.0001) and exclusive colonic location (28% vs 16%; P < 0.0001), whereas penetrating pattern (12% vs 19%; P < 0.0001) was significantly less frequent. Regarding the use of therapeutic resources, there was a significantly lower use of corticosteroids (P < 0.0001), immunosuppressants (P < 0.0001) and anti-TNFs agents (P < 0.0001) in elderly onset cases. Regarding surgery, we found a significantly higher surgery rate among elderly onset UC cases (8.3% vs 5.1%; P < 0.009). Finally, elderly onset cases were characterised by a higher rate of hospitalisations (66% vs 49%; P < 0.0001) and neoplasms (14% vs 0.5%; P < 0.0001). Elderly onset IBD shows specific characteristics and they are managed differently, with a lower use of immunosuppressants and a higher rate of surgery in UC. © 2018 John Wiley & Sons Ltd.

    Autoimmune Addison's disease (AAD) is the most frequent cause of adrenocortical insufficiency. The natural history of AAD usually comprises five consecutive stages with the first stage characterized by the increase of plasma renin consistent with the impairment of pars glomerulosa, which is usually the first affected layer of the adrenal cortex. We describe a 19-year-old female with Hashimoto's thyroiditis (HT) who underwent an autoantibody screening due to having the personal and family history of other autoimmune diseases in the absence of relevant clinical manifestations. She was positive for adrenal cortex autoantibodies (ACA) and steroid 21-hydroxylase autoantibodies (21-OH Ab) at high titers. She had increased basal levels of ACTH with normal basal cortisol not responding to ACTH stimulation, reduced levels of dehydroepiandrosterone-sulfate but normal levels of orthostatic renin and aldosterone. This scenario was consistent with a subclinical AAD presenting with first impairments in pars fasciculata and reticularis and conserved pars glomerulosa function. Only subsequently, progressive deficiency in pars glomerulosa function has become evident. Review of the literature showed that there was only one case, reported to date, with a similar atypical natural history of AAD. The strategies for screening for ACA/21-OH Ab in patients with HT are discussed.

    2012-02-01

    A Child Analysis with Anna Freud, a collection of Anna Freud's detailed case notes of her treatment of the young Peter Heller between 1929 and 1932, was first published in English in 1990. Not only does this work give us direct access to Anna Freud's ways of thinking and working at a crucial period in the early history of child analysis; it is also one of the few records of an adult reflecting in depth on the experience of being in analysis as a child. Yet to date this work has received little attention in the psychoanalytic literature. In an attempt to redress this neglect, the Heller case study is placed in the context of Anna Freud's emerging ideas about child analysis. In particular, its significance in the development of her psychoanalytic thinking is investigated in the light of her 1927 book, The Technique of Child Analysis.

    Quinn, N.K.; Sherrill, R.L.

    1992-01-01

    In February 1990, General Electric Capital Corporation (GECC), through its wholly owned subsidiary, General Electric Power Funding Corporation (GEPFC), provided a number of commitments to a partnership (the Partnership) formed by a company that develops, owns, and operates cogeneration facilities to fund the development, construction, and permanent debt and equity financing of a 614 megawatt (M) cogeneration facility (the Project) to be located near a large refinery in the northeastern United States. The Project is unusual both for the magnitude of its natural gas requirements and for its contractual configuration. The Project's entire transportation needs and a substantial portion of its gas requirements will be met by a joint venture between two local gas distribution companies (the Joint Venture), one of which is a large gas-consuming utility in the eastern United States. The Project's power purchase customer, (the Utility Host), is another very large gas-consuming utility. Thus, the fuel cost recovery of the Project is determined by the Utility Host's gas costs while its actual bill for fuel will be heavily influenced by the Joint Venture's gas commodity and transportation costs. Therefore, in appraising the credit quality of the Project's proposed fuel supply arrangements, the key issue to be answered is: Are the Project's natural gas supply and transportation arrangements compatible with the fuel cost recovery provisions of the power sales agreement with the Utility Host? If so, then the sensitivity of the Project's financing to adverse gas price movements would be minimized

    Countermatching designs can provide more efficient estimates than simple matching or case-cohort designs in certain situations such as when good surrogate variables for an exposure of interest are available. We extend pseudolikelihood estimation for the Cox model under countermatching designs to models where time-varying covariates are considered. We also implement pseudolikelihood with calibrated weights to improve efficiency in nested case-control designs in the presence of time-varying variables. A simulation study is carried out, which considers four different scenarios including a binary time-dependent variable, a continuous time-dependent variable, and the case including interactions in each. Simulation results show that pseudolikelihood with calibrated weights under countermatching offers large gains in efficiency if compared to case-cohort. Pseudolikelihood with calibrated weights yielded more efficient estimators than pseudolikelihood estimators. Additionally, estimators were more efficient under countermatching than under case-cohort for the situations considered. The methods are illustrated using the Colorado Plateau uranium miners cohort. Furthermore, we present a general method to generate survival times with time-varying covariates. Copyright © 2016 John Wiley & Sons, Ltd. Copyright © 2016 John Wiley & Sons, Ltd.

    Full Text Available Conflict is categorized as something always exist in society, people cannot be separated from conflict. Conflict causes stunted progress and development of human thought. Thus, conflicts must be immediately resolved to create a society of peace and harmony. Conflict resolution is a cultural form exists in society. Kerinci people are so familiar with conflict resolution with the term of Mandawah. In the conflict resolution of Mandawah, it is contained in traditional values that are relevant to the life of nowadays’ society. Schools do not only teach learners to master learning, but also to shape the affective aspects. Integration of conflicts resolution values in learning history is needed to improve harmonization in the life of the Kerinci society.

  1. Culture, history, and health in an Australian aboriginal community: the case of utopia.

    Anderson, Heather; Kowal, Emma

    2012-01-01

    The poor health of Indigenous Australians is well established. However, the health of residents of one remote community in the Northern Territory of Australia called Utopia has been found recently to be much better than expected. In this article, we draw on historical anthropological research to explain this finding. We trace how cultural and social structures were maintained through changing eras of government policy from the 1930s, and show how these structures strengthened psychosocial determinants of health. We argue that the mainstream psychosocial determinants of social cohesion and self-efficacy are usefully reconceptualized in an Indigenous context as connectedness to culture and land, and collective efficacy, respectively. Continuity of cultural and social structures into the 1940s was facilitated by a combination of factors including the relatively late colonial occupation, the intercultural practices typical of the pastoral industry, the absence of a mission or government settlement, and the individual personalities and histories of those connected to Utopia.

    Full Text Available This paper examines the history of archaeological research concerning the eastern coast of James Bay in northern Quebec. The construction of prehistory in northern Quebec began with the earliest contact of Europeans with Native Canadians and developed from religious explanations to Classical Evolutionary ones to Culture-Historical ones to Neoevolutionary scientific ones. Although the theoretical interpretations changed over time, the content remained surprisingly constant. The challenges of research in the area, and the resulting paucity of data, led to generalizations that telescoped thousands of years and eight million square miles into a single interpretation, based largely on eighteenth- and nineteenth-century assumptions about hunter-gatherer mobility, subsistence and social evolution. This paper traces how these assumptions have affected the archaeology of the twentieth century in James Bay and northern Quebec.

  3. Space-time clustering of non-hodgkin lymphoma using residential histories in a Danish case-control study.

    Directory of Open Access Journals (Sweden)

    Rikke Baastrup Nordsborg

    Full Text Available Non-Hodgkin lymphoma (NHL is a frequent cancer and incidence rates have increased markedly during the second half of the 20(th century; however, the few established risk factors cannot explain this rise and still little is known about the aetiology of NHL. Spatial analyses have been applied in an attempt to identify environmental risk factors, but most studies do not take human mobility into account. The aim of this study was to identify clustering of NHL in space and time in Denmark, using 33 years of residential addresses. We utilised the nation-wide Danish registers and unique personal identification number that all Danish citizens have to conduct a register-based case-control study of 3210 NHL cases and two independent control groups of 3210 each. Cases were identified in the Danish Cancer Registry and controls were matched by age and sex and randomly selected from the Civil Registration System. Residential addresses of cases and controls from 1971 to 2003 were collected from the Civil Registration System and geocoded. Data on pervious hospital diagnoses and operations were obtained from the National Patient Register. We applied the methods of the newly developed Q-statistics to identify space-time clustering of NHL. All analyses were conducted with each of the two control groups, and we adjusted for previous history of autoimmune disease, HIV/AIDS or organ transplantation. Some areas with statistically significant clustering were identified; however, results were not consistent across the two control groups; thus we interpret the results as chance findings. We found no evidence for clustering of NHL in space and time using 33 years of residential histories, suggesting that if the rise in incidence of NHL is a result of risk factors that vary across space and time, the spatio-temporal variation of such factors in Denmark is too small to be detected with the applied method.

    Historically the mass media have often been blamed for causing violent behaviour by children and young people. Two case studies of new media, film and video games, are compared in terms of their emergence, reactions to them and outcomes of the debate, mainly in the USA and Britain. Both cases are used to test the sociological model of moral panic which is found to be of limited appli­cation. It needs to be supplemented by two other concepts, those of media panic and moral regulation. Only the...

    Dotson, Ebbin; Nuru-Jeter, Amani

    2012-01-01

    Leveraging diversity to successfully influence business operations is a business imperative for many healthcare organizations as they look to leadership to help manage a new era of culturally competent, patient-centered care that reduces health and healthcare disparities. This article presents the foundation for a business case in leadership diversity within healthcare organizations and describes the need for research on managerial solutions to health and healthcare disparities. It provides a discussion of clinical, policy, and management implications that will help support a business case for improving the diversity of leadership in healthcare organizations as a way to reduce health and healthcare disparities. Historical contexts introduce aspects of the business case for leveraging leadership diversity based on a desire for a culturally competent care organization. Little research exists on the impact that the role of leadership plays in addressing health disparities from a healthcare management perspective. This article provides practitioners and researchers with a rationale to invest in leadership diversity. It discusses three strategies that will help set the stage for a business case. First, provide empirical evidence of the link between diversity and performance. Second, link investments in diversity to financial outcomes and organizational metrics of success. Third, make organizational leadership responsible for cultural competence as a performance measure. In order to address health and healthcare disparities, collaborations between researchers and practitioners are necessary to effectively implement these strategies.

    Lorenzana Claudia

    2011-10-01

    Full Text Available Abstract Introduction Cardiac tamponade is a rare manifestation of hypothyroidism, and a less rare cause of pericardial effusion. The accumulation of the pericardial fluid is gradual, and often does not compromise cardiac hemodynamic function. There is a relationship between the severity and chronicity of the disease with the presence of pericardial effusion. There are few cases describing associated pericardial tamponade published in the literature. When a tamponade occurs, a concomitant provocative factor such as a viral pericarditis may be related. Our patient's case appears to be the youngest patient described so far. Case presentation We report the case of a previously healthy five-year-old Hispanic (non-indigenous boy who developed rhabdomyolysis with a history of a recent pericardial effusion and tamponade two months before that required the placement of a percutaneous pericardial drainage. Pericardial effusion was considered to be viral. Later on readmission, clinical primary hypothyroidism was diagnosed and thought to be associated with the previous cardiac tamponade. He developed rhabdomyolysis, which was considered to be autoimmune and was treated with steroids. The level of creatine phosphate kinase and creatine kinase MB fraction returned to within the reference rangeone week after our patient was started on steroids and three weeks after he was started on thyroid hormones. Conclusions Physicians should consider hypothyroidism as a differential diagnosis in patients with pericardial effusion. Pericardial effusion may progress and cause a cardiac tamponade with hemodynamic instability. The fact that our patient did not have any manifestations of hypothyroidism might have delayed diagnosis.

    2016-08-01

    To report a case of severe pigmentary glaucoma (PG) in a 13-year-old boy of a family affected by pigment dispersion syndrome (PDS). A 13-year-old child was referred to our hospital for severe bilateral glaucoma. A complete ophthalmologic evaluation including refraction, intraocular pressure, central corneal thickness, slit-lamp biomicroscopy, gonioscopy, fundus examination, and ultrasound biomicroscopy was performed. Family members were also examined and a family pedigree was obtained. Ophthalmologic examination revealed a severe bilateral PG with Krukenberg spindle and a widely open heavily pigmented iridocorneal angle. Ultrasound biomicroscopy showed a deep anterior chamber with pronounced iris concavity in both eyes. Within his family, his 15-year-old sister and 7-year-old brother were both affected by PDS diagnosed on gonioscopy findings. We report for the first time a severe case of pediatric PG with a family history of PDS. This case demonstrates that accurate screening is necessary in cases of familial PDS and PG, even in the pediatric population.

  12. Independent life history evolution between generations of bivoltine species: a case study of cyclical parthenogenesis.

    Science.gov (United States)

    Hood, Glen R; Ott, James R

    2017-04-01

    Successive generations of bi- and multivoltine species encounter differing biotic and abiotic environments intra-annually. The question of whether selection can independently adjust the relationship between body size and components of reproductive effort within successive generations in response to generation-specific environmental variation is applicable to a diversity of taxa. Herein, we develop a conceptual framework that illustrates increasingly independent life history adjustments between successive generations of taxa exhibiting complex life cycles. We apply this framework to the reproductive biology of the gall-forming insect, Belonocnema treatae (Hymenoptera: Cynipidae). This bivoltine species expresses cyclical parthenogenesis in which alternating sexual and asexual generations develop in different seasons and different environments. We tested the hypotheses that ecological divergence between the alternate generations is accompanied by generational differences in body size, egg size, and egg number and by changes in the relationships between body size and these components of reproductive effort. Increased potential reproductive effort of sexual generation B. treatae is attained by increased body size and egg number (with no trade-off between egg number and egg size) and by a significant increase in the slope of the relationship between body size and potential fecundity. These generation-specific relationships, interpreted in the context of the model framework, suggest that within each generation selection has independently molded the relationships relating body size to potential fecundity and potential reproductive effort in B. treatae. The conceptual framework is broadly applicable to comparisons involving the alternating generations of bi- and multivoltine species.

    Yongwook Yoo

    2014-02-01

    Full Text Available This article intends to furnish a narrative story-telling with the broad perspective on the human past rather than simply depending on the analytical examination of archaeological data. For the purpose of this task, Ferdinand Braudel’s concept of “la longue durée” is applied to parallel the environmental background and hominid’s life/land-use patterns based on the geological data and archaeological remains. The Imjin-Hantan River Area (IHRA, known for the discovery of Acheulian-like handaxe, was occupied from ca 0.23 mya to the final Pleistocene; the hominids continuously changed their residing patterns in the landscape with actively modifying the lithic technological organization as a response to the environmental change. Integrating the geological features, absolute dates and characteristics of lithic assemblages from individual sites, we can recognize six phases of environmental changes based on the development of river channel system. These six phases witness different patterns of hominid’s adaptation in this area and correspondingly yield different mode of raw material utilization and lithic procurement. While more accurate geological dates are yet to be published and the description of lithic assemblages may be changed by new data, it is prospecting that Braudel’s la longue durée is a useful concept for meaningfully narrating a long-term human occupation history in the discipline of prehistoric archaeology.

  14. Hypochondria as an actual neurosis.

    Science.gov (United States)

    Nissen, Bernd

    2017-09-27

    Freud defined hypochondria as an actual neurosis. In this paper the actual neurosis will be interpreted as unbound traumatic elements which threaten the self. In severe hypochondria, breakdowns have occurred, as outlined by Winnicott. The nameless traumatic elements of the breakdown have been encapsulated. The moment these encapsulated elements are liberated, an actual dynamic takes place which threatens the self with annihilation. Projective identification is not possible because no idea of containment exists. The self tries to evacuate these elements projectively, thus triggering a disintegrative regression. However, the object of this projection, which becomes a malign introject, is felt to remove the remaining psychical elements, forcing the worthless residue back into the self. In a final re-introjection, the self is threatened by unintegration. To save the self, these elements are displaced into an organ which becomes hypochondriacal, an autistoid object, protecting itself against unintegration and decomposition. An autistoid dynamic develops between the hypochondriac organ, the ego and the introject. Two short clinical vignettes illustrate the regressive dynamical and metapsychological considerations.

    One of the most hazardous diseases that is commonly associated with the coal mining industry is Silicosis which caused by dust inhalation. This disease occurs as a result of prolonged breathing of dust containing silica (quartz). The generation of coal mine dust during underground and surface coal mining is the most significant source of coal dust exposure. Silica dust develops scar tissue inside the lungs which reduces the lungs ability to extract oxygen from the air. All miners working in underground and surface coal mines are at risk of being exposed to mine dust containing silica. In this study, cases with pathologic diagnosis of silicosis during seven years period between 2000 and 2007 were retrieved, from the pathologic file of Department of Pathology, Massih Daneshvary Hospital in Iran. Results of this case study showed the great effects of dust exposure and inhalation from the viewpoint of symptoms especially between the miners.

    2013-04-23

    A historical examination of a nursing curriculum is a bridge between past and present from which insights to guide curriculum development can be gleaned. In this paper, we use the case study method to examine how the University of Victoria School of Nursing (UVic SON), which was heavily influenced by the ideology of second wave feminism, contributed to a change in the direction of nursing education from task-orientation to a content and process orientation. This case study, informed by a feminist lens, enabled us to critically examine the introduction of a "revolutionary" caring curriculum at the UVic SON. Our research demonstrates the fault lines and current debates within which a feminist informed curriculum continues to struggle for legitimacy and cohesion. More work is needed to illuminate the historical basis of these debates and to understand more fully the complex landscape that has constructed the social and historical position of women and nursing in Canadian society today.

    The purposes of this study were to describe 2 contact lens-associated Beauveria keratitis cases and to compare the isolates of 3 contact lens-associated Beauveria keratitis cases with Beauveria-based biopesticides using random amplification of polymorphic DNA (RAPD). A 55-year-old diabetic woman from New Mexico and a 31-year-old healthy woman from southern Wisconsin developed soft contact lens-related corneal ulcers unresponsive to topical moxifloxacin and prednisolone acetate drops. Their corneal cultures grew B. bassiana. These isolates, an isolate from a third soft contact lens-related Beauveria keratitis case, and Beauveria-based biopesticides sold in the United States were analyzed using morphological features, DNA sequencing, and RAPD. A PubMed, Cochrane Library, OVID, UpToDate, and Google search using the term "Beauveria" found only 9 reported Beauveria keratitis infections. Patient 1 responded to topical natamycin, ketoconazole, and 200 mg oral ketoconazole twice daily before developing a secondary bacterial infection requiring penetrating keratoplasty. After subsequent cataract surgery, the best-corrected visual acuity was 20/20. Patient 2 was treated with topical natamycin, topical amphotericin, and 200 mg oral voriconazole twice daily for 1 month with residual scarring and a best-corrected visual acuity of 20/25. RAPD showed that all isolates were unrelated. Although earlier reported Beauveria keratitis cases occurred after corneal injury in patients who did not wear contact lenses, 3 recent patients wore soft contact lenses and denied trauma, mirroring a changing trend in microbial keratitis. RAPD analysis showed that the Beauveria isolates were unrelated to one another and to Beauveria-based biopesticides. In Patient 2, oral voriconazole worked well.

    The paper aims to inform historically the analyses of future sociotechnical transition pathways in the electricity sector, particularly those developed by the Transition Pathways to a Low Carbon Economy project. It also aims to inform the theoretical approach to transitions by focusing on key decisions at ‘branching points’ that led to transitions in the UK gas energy services regime, which occurred under different governance patterns. The first historical case study covers the market-led transformation of the manufactured gas regime from 1877 to 1914, which developed the end-uses of gas beyond lighting to include cooking, and extended access to working class consumers. The second case study covers the period from 1948 to 1977, historically reconstructing the transition from town gas to natural gas. This state-led and coordinated conversion to natural gas was preceded by a period of destabilisation of the manufactured gas regime, the co-existence of several niche technologies and the hybridisation of the key actors and technological infrastructures of the incumbent regime. Comparing the cases provides insights for future energy service transitions by addressing the significance of power, trust and networking in the decision making processes involved in the governance of energy transitions. - Highlights: ► Historical work is useful in understanding socio-technical energy transitions. ► Different governance modes have led to transitions with different characteristics. ► Gas regimes operating under market and state ‘logics’ took decisions differently. ► Decisions at key branching points led to path dependency, affecting later decisions. ► Agency, governance and trust were important elements in the transitions analysed.

  1. Management of Amelogenesis Imperfecta: A 15-Year Case History of Two Siblings.

    Amelogenesis imperfecta (AI) is a heterogenous genetic disorder that interferes with normal enamel formation in the absence of systemic disorders. The patients' main concerns are caries susceptibility, poor esthetics, and generalized sensitivity. There is a broad clinical spectrum, from discolorations to consequent enamel alterations. This case report describes the 15-year case study and the full-mouth rehabilitation of two siblings affected by a hypocalcified AI. Clinical Considerations: In these two patients, conservative care with stainless steel crowns and direct composite restorations was undertaken to restore function and esthetics and to reduce sensitivities in primary and mixed dentitions. The difficulties in monitoring resulted in severe infectious complications (dental abscess with cutaneous fistula), important dental defects, and loss of spaces with subsequent malocclusion. In the young adult dentition, they were treated by extractions, root canal therapies, and new restorations: stainless steel crowns for permanent molars, direct composite restorations (with strip crowns) for incisors and maxillary canines (to improve the crown morphology as well as to mask the discolorations and the malpositions), and adjusted composite crown molds using a thermoforming procedure for premolars and the mandibular canines. The main difficulties were rapid tooth surface loss, bonding to atypical enamel, developing dentition, long-term follow-up. Restoring function and esthetics in AI-affected patients is a challenge from primary to adult dentition. Early corrections are essential to avoid dental damage and for psychological benefits. This clinical report highlights the adhesive rehabilitation for anterior and premolar areas and the difficulty of patient follow-up.

  2. Ocean disposal option for bulk wastes containing naturally occurring radionuclides: an assessment case history

    There are 180,000 m 3 of slightly contaminated radioactive wastes (36 pCi/g radium-226) currently stored at the US Department of Energy's Niagara Falls Storage Site (NFSS), near Lewiston, New York. These wastes resulted from the cleanup of soils that were contaminated above the guidelines for unrestricted use of property. An alternative to long-term management of these wastes on land is dispersal in the ocean. A scenario for ocean disposal is presented for excavation, transport, and emplacement of these wastes in an ocean disposal site. The potential fate of the wastes and impacts on the ocean environment are analyzed, and uncertainties in the development of two worst-case scenarios for dispersion and pathway analyses are discussed. Based on analysis of a worst-case pathway back to man, the incremental dose from ingesting fish containing naturally occurring radionuclides from ocean disposal of the NFSS wastes is insignificant. Ocean disposal of this type of waste appears to be a technically promising alternative to the long-term maintenance costs and eventual loss of containment associated with management in a near-surface land burial facility

    Full Text Available This article sets contemporary challenges to good water governance in South Africa within an important historical context. While it is correct to say that 'the world water crisis is a crisis of governance', it is problematic to assume that all states can follow a similar path toward environmentally sustainable, economically efficient and socially equitable water resources governance and management. The nexus of decision-making power varies within and beyond states, and over time. Gramsci (1971 describes this as the "constellation of social forces". Where this constellation of social forces achieves consensus, a 'historic bloc' is said to emerge giving rise to a particular state form. The South African state form has varied greatly over several centuries, giving rise to various historic blocs. The resulting body of laws and policies and the varied forms of infrastructure that were developed to harness water for multiple social practices over time constitute a complex political ecological terrain not easily amenable to oversimplified frameworks for good water governance. This article outlines the role of water in the history of South Africa’s multiple state forms. It shows that over time, water policy, law and institutions came to reflect the increasingly complex needs of multiple actors (agriculture, mining, industry, cities, the newly enfranchised represented by different state forms and their characteristic political regimes: the Dutch East India Company; the British Empire; the Union of South Africa; the apartheid and post-apartheid republics. Authoritarian, semi-authoritarian and democratic state forms have all used central-state power to serve particular interests. Through time, this constellation of social forces has widened until, today, the state has taken upon itself the task of providing "some water for all forever" (slogan of the Department of Water Affairs. As this article suggests, despite the difficult challenges presented by a

    Heterotopic pregnancy refers to the simultaneous development of an intrauterine pregnancy and an extrauterine pregnancy. We experienced a case of a ruptured heterotopic pregnancy for a patient with a history of a right segmental salpingectomy from an ectopic pregnancy. The 30-year-old patient with amenorrhea for six weeks complained of lower abdominal pain with hypovolemic shock. Transabdominal ultrasonography showed diffuse hemoperitoneum with a structure similar to an ectatic tube or a deformed cyst with no echogenic double ring or peripheral hypervascularity in the right adnexa and an intrauterine gestational sac. We considered a ruptured corpus luteum cyst as an ultrasonographic finding and found a ruptured tubal mass in the right salpinx and hemoperitoneum through an emergency laparotomy. We performed a right salpingectomy, and the histopathologic report confirmed ectopic pregnancy.

    Air quality control by a system of monitoring station is indispensable for the environmental protection. Moreover, a monitoring network have not to be only a mere data collection a good air quality control is possible only if the network management allows to prevent unacceptable pollutants level. In other terms, elaboration and interpretation data are fundamental in order to make monitoring system really able for regulations of corrective measures as, for example, the reduction of local emissions. The case of monitoring network run from the Industrial Society CIPA of Siracusa (Italy) is discussed. The management of the data obtained from a continuous survey allows to keep pollutants level below the current limits set down by the Italian law. Furthermore, elaboration of the data allows useful evaluations about atmospheric dispersion phenomena. (author)

    Due to the advent of antibiotics, mycotic aneurysms, also known as infective aneurysms, now represent only 2.5-5% of all aneurysms. The existing research on this topic is old and scarce. It is highly probably that a neuroscience nurse will care for this type of patient at some point during his/her career. The patient with a mycotic aneurysm is usually critically ill. A 46% mortality has been noted and is related to the multiple problems of these types of patients. Currently, if and when to surgically intervene is controversial. The case of "Mr. C.", a patient at the Montreal Neurological Hospital who developed a mycotic aneurysm secondary to subacute bacterial endocarditis, will be presented. His course in hospital, the medical management and treatment as well as the nursing care and educational needs will be described.

    Several pathogenic fungi and cases related to Japanese medical mycologists were reviewed. Trichosporon inkin (as Sarcinomyces inkin) was reported as a pathogen of scrotal lesion by Oho in 1921, and Trichosporon asahii was isolated from generalized keratotic lesions in 1922 by Akagi in Japan. They were once included in Trichophyton beigelii, but then based on revision using DNA molecular technology, were returned to their original names.Microsporum ferrugineum was reported by Ota as a causative dermatophyte of tinea capitis in Japan and surrounding areas. It was once classified under the genus Trichophyton, but after the discovery of characteristic rough-walled macroconidia belonging to genus Microsporum, the fungus was again assigned to the original name.

    Gorman, Michael E.; Robinson, J. Kirby

    This paper shows how a historical case, the invention of the telephone, can be used to teach invention and design in a way that combines engineering, social sciences, and humanities. The historical problem of transmitting speech was turned into an active learning module, in which students sought to improve patents obtained by early telephone inventors like Alexander Graham Bell and Elisha Gray, using equipment similar to what was available at the time. The result was a collaborative learning environment in which students from a wide range of majors worked in teams, eventually producing a patent application. As part of the project, they were allowed to search historical materials like the Bell notebooks, which were made available on line. This experience gave them a better understanding of the invention and design process.

    Full Text Available This article discusses the way Islam transformed into an ideology that potentially used as justification for violence. By analising the case of the murder of Teungku Ayub, leader of a small circle for basic religious learning (pengajian in Bireun, Aceh, in 2012, the study reveals to the role of Islam as an ideology of mass movement to cleanse deviant tenet (aliran sesat among the Acehnese. This is because of two reasons. First, the term of the veranda of Mecca (serambi Mekkah remains considered as “holy word” in the Acehnese society today, which supports any Islamic agenda of purifying Aceh from aliran sesat. Secondly, the adoption of Islam into a formal body of state (Aceh province represented by the implementation of Islamic law (sharīʻah. Both reasons above strengthen ulama in Aceh to facilitate the mass movement in the name of religion as well as the rationale background of the murder of Teungku Ayub.

    Prior studies suggest that history of allergy and infections early in life might be inversely associated with cancer. We explored the association between allergies, recent influenza infections and laryngeal cancer risk. We used data from a case-control study which included 229 cases of laryngeal cancer and 769 population controls matched for age and sex. History of a physician-diagnosed allergy, influenza-like infections in the past 5 years, smoking, alcohol consumption and occupational exposure to carcinogens were self-reported. Allergies were classified into two groups (Type I and Type IV), according to the underlying immunologic mechanism. Conditional logistic regression models were fitted using laryngeal cancer as the outcome, adjusting for smoking, alcohol consumption and occupational exposure and stratified for age and sex. Having any allergy was not associated significantly with laryngeal cancer. Although Type I and Type IV allergies were non-significantly associated with laryngeal cancer, Type IV allergies showed a strong inverse association after adjusting for smoking and alcohol (OR 0.50, 95 % CI 0.22-1.2). Participants who reported at least one influenza-like infection during the past 5 years were significantly less likely to have laryngeal cancer (OR 0.57, 95 % CI 0.39-0.81). After considering fever (≥38.5 °C) as a criterion for influenza infection, the association between influenza infection and laryngeal cancer was even stronger (OR 0.29, 95 % CI 0.13-0.63). We found no significant association between any allergy and laryngeal cancer, some indication of an inverse association between Type IV allergy and laryngeal cancer, whereas recent influenza infections were inversely associated with laryngeal cancer risk.

    Cleft lip and/or cleft palate (CL ± P) are among the most common congenital anomalies. Nevertheless, their etiologies remain poorly understood. Several studies have demonstrated increased rates of cancer among patients with CL ± P and their relatives, as well as increased risk of CL ± P among family members of cancer survivors. In addition, a number of possible genetic associations between cancer and CL ± P have been identified. However, these studies are limited by confounding factors that may be prevalent in these patients, such as tobacco exposure and perinatal complications.The purpose of this study was to quantitatively evaluate the association between family history of cancer and development of CL ± P in the child. A case-control study was conducted at the Cleft Hospital and the Bashir Hospital in Gujrat, Pakistan from December 2015 to December 2016. All new cases of CL ± P at the Cleft Hospital were included. Sociodemographically similar patients without congenital malformations at the Bashir Hospital served as controls. Risk factors associated with CL ± P were identified through bivariate analyses. Multiple logistic regressions were performed to calculate adjusted odds ratios of developing CL ± P. There were 137 patients with CL ± P and 147 controls in the study. The following factors were statistically significantly associated with development of cleft: history of cancer in the family (P consanguineous marriage (parents are first or second cousins) (P = 0.03), lower socioeconomic status (P relationship between CL ± P and cancer that has been adjusted for confounders traditionally associated with patients with CL ± P, thereby supporting the evidence of shared environmental and/or genetic etiologies.

    The history of Melito Irpino, a small village in southern Italy is particular, though not unique in its genre. The development of its urban asset was, in fact, strongly affected by natural disasters such as hydrogeological and seismic events, which determined its transfer to another location. Due to its landslides and flooding it has been included since the beginning of the twentieth century among the unstable centers to be consolidated. The landslides were caused by peculiar geological characteristics of which the substrate essentially origins from different consistency Flysch elements. From the seismic point of view, Melito Irpino is part of the first category of the new seismic classification of the Campania Region. The most devastating earthquakes that damaged Melito date back to December 1456, which hit central and southern Italy and 5th June , 1688 which had the Sannio as epicentral area, both with l0 = XI MCS and M> 7 [1456: l0= XI MCS, Mw 7.2; 1688: l0 = XI MCS, Mw 7.O.] During the twentieth century, it was involved in two other disastrous earthquakes that caused serious damage to the village in 1930 with an intensity VIII and in 1962 with I = IX MCS and VIII ESI-07 intensity. The earthquake of 21st August 1962 was fatal for the village of Melito. In December of the same year it was left with 2182 inhabitants and 800 houses, most of which were unstable, 300 were to be demolished, 50 unrepairable and 200 were still uninhabitable yet repairable. From a geological point of view the situation turned even more dramatically when the whole valley area stretching from the old Ufita River bridge and the historical center of Melito was affected by a series of large slope instability such as rock falls, complex rotational slip, de facto complicating an extremely compromised situation. This was sufficient to encourage the transfer of the entire village in an other location. After more than half a century and considering the effects of two important earthquakes in 1962

    Residential thermostats have been a key element in controlling heating and cooling systems for over sixty years. However, today's modern programmable thermostats (PTs) are complicated and difficult for users to understand, leading to errors in operation and wasted energy. Four separate tests of usability were conducted in preparation for a larger study. These tests included personal interviews, an on-line survey, photographing actual thermostat settings, and measurements of ability to accomplish four tasks related to effective use of a PT. The interviews revealed that many occupants used the PT as an on-off switch and most demonstrated little knowledge of how to operate it. The on-line survey found that 89% of the respondents rarely or never used the PT to set a weekday or weekend program. The photographic survey (in low income homes) found that only 30% of the PTs were actually programmed. In the usability test, we found that we could quantify the difference in usability of two PTs as measured in time to accomplish tasks. Users accomplished the tasks in consistently shorter times with the touchscreen unit than with buttons. None of these studies are representative of the entire population of users but, together, they illustrate the importance of improving user interfaces in PTs.

    2015-01-15

    The world is seemingly facing a global increase in people suffering from diabetes especially in developing countries. The worldwide occurrence of diabetes for all age groups in year 2000 was estimated to be 2.8% and this number is most certainly expected to rise to 4.4% by 2030. Maturity-onset of diabetes of the young, or MODY, is a form of monogenic diabetes that is caused by mutations occurring in a number of different genes. Mutations in different genes tend to cause a slightly different variant of diabetes. MODY is typically diagnosed during late childhood, adolescence, or early adulthood and is usually observed to develop in adults during their late 50's. One of the main drawbacks in its diagnosis is that many people with MODY are misdiagnosed as having type 1 or type 2 diabetes. However, a molecular and genetic diagnosis can result in a better treatment and could also help in identifying other family members with MODY. This article explores the historical prospect and the genetic background of MODY, a brief summary of the first case reported and the significant factors that differentiate it from type 1 and type 2 diabetes.

    1994-01-01

    This paper provides an overview of the automated disposal system for produced water designed and operated by Taurus Exploration, Inc. This presentation draws from Taurus' case study in the planning, design, construction, and operation of production water disposal facilities for the Mt. Olive well field, located in the Black Warrior Basin of Alabama. The common method for disposing of water produced from coalbed methane wells in the Warrior Basin is to discharge into a receiving stream. The limiting factor in the discharge method is the capability of the receiving stream to assimilate the chloride component of the water discharged. During the winter and spring, the major tributaries of the Black Warrior River are capable of assimilating far more production water than operations can generate. During the summer and fall months, however, these same tributaries can approach near zero flow, resulting in insufficient flow for dilution. During such periods pumping shut-down within the well field can be avoided by routing production waters into a storage facility. This paper discusses the automated production water disposal system on Big Sandy Creek designed and operated by Taurus. This system allows for continuous discharge to the receiving stream, thus taking full advantage of Big Sandy Creek's assimilative capacity, while allowing a provision for excess produced water storage and future stream discharge

    The commencement of a UNDP/IAEA uranium exploration project in Northern Greece in 1971 offered the opportunity to test and apply an exploration strategy based on a phased use of geochemical exploration methods. The paper reviews the exploration task, the strategy selected, and some results obtained. The project area (22000 km 2 ) was explored by car-borne survey, covering 15000 km of road and track. Concurrently, a stream sediment geochemical survey was begun which aimed at a nominal sample density of one sample per square kilometre. Samples were analysed for copper, lead, zinc, silver, cobalt, nickel, molybdenum, mercury and manganese, in addition to uranium. At each site, a general reading of radioactivity was made, and treated like another element analysis. The reconnaissance programme succeeded in delineating a number of important target areas, varying in size from a few to several hundred square kilometres with significant uranium potential. Follow-up and detailed surveys have been carried out over a number of these, including a sedimentary basin of continental deposits which have been found to contain occurrences of secondary uranium minerals, and two areas in which granitic bodies have been found to have fracture systems and secondary uranium mineralization of economic interest.

    Horizontal wells are commonly used in Saudi Arabia because they have proven advantages in optimizing production and cost. However, in order to ensure proper production, these wells occasionally require downhole measurements of the flow profile; wellbore parameters such as water entry points; and productivity index for remedial action, such as water shut off or well stimulation. Evaluating the performance of a well also contributes to a better understanding of sweep, water production and cross flow, particularly in long reach wells. The most common flow regime at downhole conditions is a stratified flow regime in which lighter oil flows on top and heavier water flows on bottom. Slugging and bubbling flow regimes are typical of low oil flow rate and are considered unstable flow regimes. This paper described a new generation of production logging tools (PLTs) that have been used on some horizontal wet producers located in Saudi Arabia. The new PLTs consists of arrays of spinners and sensors to log the entire cross section to describe the horizontal flow regime and measure the downhole production and phases. In an effort to find the best logging procedure, the PLT was tested using two methods, notably coiled tubing (CT) and wireline tractor. It was concluded that PLTs are reliable and accurate. Case studies involving planning, deployment, data acquisition, and detailed analysis of PLTs were presented. 35 refs., 1 tab., 20 figs.

    Clean Air Act Amendments being considered by Congress require SO 2 emissions reductions from numerous large power generation sources nationwide. As currently written, these amendments also require that the affected sources must continue to comply with all provisions of the existing Clean Air Act while achieving the required reductions. United Engineers and Constructors is presently assisting utilities in the evaluation of compliance options for units totaling over 18,000 MW. The methods of achieving compliance with the probable requirements of the Act most often include the retrofit installation of SO 2 scrubbers. A study designed to determine permitting issues and the scope of air quality analyses required to demonstrate the regulatory acceptability of installation of wet scrubbing systems has been completed for units totaling a portion of the above-referenced 18,000 MW. The study results show that, under certain commonly occurring circumstances, there is a risk of creating National Ambient Air Quality Standards contraventions for SO 2 and NO 2 when scrubbers are installed at an existing facility. Any such contraventions subject the plant to state and/or federal enforcement actions. In addition, installation of materials handling equipment for lime stone can trigger Prevention of Significant Deterioration requirements as a major modification. This paper is divided into two major areas. The first deals with the air quality regulatory requirements imposed upon installation of pollution control equipment. The first section is further sub-divided into two sections: one covering requirements emanating from the 1977 Clean Air Act Amendments and its implementing regulations and the other the regulatory requirements of the new Clean Air Act Amendments. This section on regulatory requirements provides background information for the understanding of the second major section of the paper which gives the results of the hypothetical case study

    Familial cancer can be used to leverage genetic association studies. Recent genome-wide association studies have reported independent associations between seven single nucleotide polymorphisms (SNPs) and risk of glioma. The aim of this study was to investigate whether glioma cases with a positive family history of brain tumours, defined as having at least one first- or second-degree relative with a history of brain tumour, are associated with known glioma risk loci. One thousand four hundred and thirty-one glioma cases and 2,868 cancer-free controls were identified from four case-control studies and two prospective cohorts from USA, Sweden and Denmark and genotyped for seven SNPs previously reported to be associated with glioma risk in case-control designed studies. Odds ratios were calculated by unconditional logistic regression. In analyses including glioma cases with a family history of brain tumours (n = 104) and control subjects free of glioma at baseline, three of seven SNPs were associated with glioma risk: rs2736100 (5p15.33, TERT), rs4977756 (9p21.3, CDKN2A-CDKN2B) and rs6010620 (20q13.33, RTEL1). After Bonferroni correction for multiple comparisons, only one marker was statistically significantly associated with glioma risk, rs6010620 (ORtrend for the minor (A) allele, 0.39; 95% CI: 0.25-0.61; Bonferroni adjusted ptrend , 1.7 × 10(-4) ). In conclusion, as previously shown for glioma regardless of family history of brain tumours, rs6010620 (RTEL1) was associated with an increased risk of glioma when restricting to cases with family history of brain tumours. These findings require confirmation in further studies with a larger number of glioma cases with a family history of brain tumours. Copyright © 2012 UICC.

  6. A case study of systemic curricular reform: A forty-year history

    Laubach, Timothy Alan

    What follows is a description of the development of a particular inquiry-based elementary school science curriculum program and how its theoretical underpinnings positively influenced a school district's (K-12) science program and also impacted district- and state-wide curriculum reform initiatives. The district's science program has evolved since the inception of the inquiry-based elementary school science curriculum reform forty years ago. Therefore, a historical case study, which incorporated grounded theory methodology, was used to convey the forty-year development of a science curriculum reform effort and its systemic influences. Data for this study were collected primarily through artifacts, such as technical and non-technical documents, and supported and augmented with interviews. Fifteen people comprised the interview consortium with professional responsibilities including (a) administrative roles, such as superintendents, assistant superintendents, principals, and curriculum consultants/coordinators; (b) classroom roles, such as elementary and secondary school teachers who taught science; (c) partnership roles, such as university faculty who collaborated with those in administrative and classroom positions within the district; and (d) the co-director of SCIS who worked with the SCIS trial center director. Data were analyzed and coded using the constant comparative method. The analysis of data uncovered five categories or levels in which the curriculum reform evolved throughout its duration. These themes are Initiation, Education, Implementation, Confirmation, and Continuation. These five categories lead to several working hypotheses that supported the sustaining and continuing of a K-12 science curriculum reform effort. These components are a committed visionary; a theory base of education; forums promoting the education of the theory base components; shared-decision making; a university-school partnership; a core group of committed educators and teachers

    Smallpox inoculation was one of the great discoveries of the 18th century and has been written into the grand narrative of medical progress, describing the taming of epidemic disease. Setting the perspective of progress aside, the article explores how this medical innovation was situated in 18th-century society and culture. The aim is to investigate how medical practice was intertwined with social structure and cultural patterns. The article takes its case from a book published in Copenhagen in 1766 by Professor C. F. Rottböll, former Head Physician of the Royal Inoculation House in Copenhagen. Being the first medical treatise on inoculation in Denmark-Norway, the book also has a historical section followed by a collection of reports and letters written by a number of other authors from various parts of the kingdom. Through close reading, the article explores how the introduction of the new technique was described in the texts. The reports were written to present practice and discuss cases. In doing so, they also presented a variety of other concerns so that a diversity of aims and intentions are added to the medical ones. The social and rhetorical strategies employed illuminate social ambition and systems of patronage, as well as understandings of history and of truth.

    An international body of scientific research indicates that growth of job insecurity and precarious forms of employment over the past 35 years have had significant negative consequences for health and safety. Commonly overlooked in debates over the changing world of work is that widespread use of insecure and short-term work is not new, but represents a return to something resembling labor market arrangements found in rich countries in the 19th and early 20th centuries. Moreover, the adverse health effects of precarious employment were extensively documented in government inquiries and in health and medical journals. This article examines the case of a large group of casual dockworkers in Britain. It identifies the mechanisms by which precarious employment was seen to undermine workers and families' health and safety. The article also shows the British dockworker experience was not unique and there are important lessons to be drawn from history. First, historical evidence reinforces just how health-damaging precarious employment is and how these effects extend to the community, strengthening the case for social and economic policies that minimize precarious employment. Second, there are striking parallels between historical evidence and contemporary research that can inform future research on the health effects of precarious employment.

En primer lugar, se describe la comunidad de usuarios a nivel global, focalizando en el uso actual que el software ha alcanzado en Argentina: la cantidad de implementaciones disponibles, su evolución, el tipo, tamaño y variedad de los desarrollos existentes, así como su aplicación a la gestión de repositorios digitales de ciencia y tecnología en el ámbito de las instituciones científicas, tecnológicas y de educación superior en Argentina. En segundo lugar, se detallan las acciones llevadas a cabo a partir de la creación del Centro Nacional de Promoción de Greenstone en Argentina en 2009. Datos recabados en encuestas realizadas permitieron observar que las razones predominantes para elegir esta plataforma fueron, entre otras, su facilidad de instalación y configuración, su bajo nivel de requerimiento tecnológico, la generalizada escasez de recursos humanos dedicados a esta actividad, y la complejidad que presentaban los softwares alternativos existentes en ese momento. A lo largo de estos 8 años, tanto los repositorios digitales como los sistemas que los soportan evolucionaron drásticamente, modificando el escenario actual. Paralelamente, en 2016 la nueva versión mayor de Greenstone implementó una reingeniería completa del software para su adaptación a las tecnologías en uso: XML, XSLT, Web-services y Java. Como consecuencia de esto, la comunidad de desarrollo local se plantea nuevos desafíos para la migración de las bibliotecas digitales y repositorios implementados con versiones anteriores.

In operational terms, this translates into solutions that are as lifelike as possible and guarantee the maximum emotional involvement of the viewer, adopting the same techniques as are used in modern cinema. Communication thus becomes entertainment and a vehicle for high-quality content, aimed at the widest possible public and produced with the help of interdisciplinary tools and methods. In this context, high-end technologies are no longer the goal of research; rather they are the invisible engine of an unstoppable process that is making it harder and harder to distinguish between computer images and real objects. An emblematic case in this regard is the reconstructive study of ancient contexts, where three-dimensional graphics compensate for the limited expressive potential of two-dimensional drawings and allows for interpretative and representative solutions that were unimaginable a few years ago.

  12. Iron, Engineering and Architectural History in Crisis: Following the Case of the River Dee Bridge Disaster, 1847

    Directory of Open Access Journals (Sweden)

    William Max Taylor

    2013-10-01

    Full Text Available This paper establishes relations—historical, material and evidential connections—between two responses to a ‘crisis’. The first features in the history of industrialised iron construction, specifically period reporting on the spectacular collapse of the River Dee bridge in Cheshire, England, in 1847. The second response highlights a blind spot in the historiography of modern architecture. Robert Stephenson became suspect when his cast- and wrought-iron railway bridge across the River Dee failed, resulting in death and injury and continuing uncertainty as to its cause. At the time the incident sparked national furore, setting off a coroner’s inquest followed by a Royal Commission into the perilous state of Britain’s bridges. The inquest jury concluded no one was to blame; rather, it was an accident brought about by use of iron, an uncertain and “treacherous” metal. This explanation has failed to satisfy contemporary materials specialists who have reopened the case, albeit under different terms of reference.      The paper examines the initial verdict, firstly, in view of aspects of the social context of evidence and proof prevailing at the inquest and, secondly, given historical writing on iron construction whereby the inquest’s seemingly imprecise and arbitrary judgment is taken as sign of the subsequent progress of engineering as a practical and moral science. This paper adopts the leitmotif of ‘crisis’ to highlight a parallel history that challenges progressivist narratives of industrialised iron construction and modernist architecture. It invites reflection on the provenance and unstable forms of agency associated with engineering as a propositional and socially contingent enterprise.

    Mammographic density has been shown to be a strong independent predictor of breast cancer and a causative factor in reducing the sensitivity of mammography. There remain questions as to the use of mammographic density information in the context of screening and risk management, and of the association with cancer in populations known to be at increased risk of breast cancer. To assess the association of breast density with presence of cancer by measuring mammographic density visually as a percentage, and with two automated volumetric methods, Quantra™ and VolparaDensity™. The TOMosynthesis with digital MammographY (TOMMY) study of digital breast tomosynthesis in the Breast Screening Programme of the National Health Service (NHS) of the United Kingdom (UK) included 6020 breast screening assessment cases (of whom 1158 had breast cancer) and 1040 screened women with a family history of breast cancer (of whom two had breast cancer). We assessed the association of each measure with breast cancer risk in these populations at enhanced risk, using logistic regression adjusted for age and total breast volume as a surrogate for body mass index (BMI). All density measures showed a positive association with presence of cancer and all declined with age. The strongest effect was seen with Volpara absolute density, with a significant 3% (95% CI 1-5%) increase in risk per 10 cm 3 of dense tissue. The effect of Volpara volumetric density on risk was stronger for large and grade 3 tumours. Automated absolute breast density is a predictor of breast cancer risk in populations at enhanced risk due to either positive mammographic findings or family history. In the screening context, density could be a trigger for more intensive imaging. Copyright © 2017 The Authors. Published by Elsevier Ltd.. All rights reserved.

    Full Text Available Introduction: Primary dermal melanoma (PDM is a recently described clinical entity accounting for less than 1% of all melanomas. Histologically, it is located in the dermis or subcutaneous tissue, and it shows no connections with the overlying epidermis. The differential diagnosis is principally made along with that of metastatic cutaneous melanoma. Case Report: A 72-year-old Caucasian woman with a history of multiple cancers (metachronous bilateral breast cancer, meningioma, clear cell renal cell carcinoma, uterine fibromatosis and intestinal adenomatous polyposis, came to our attention with a nodular lesion on her back. After removal of the lesion, the histology report indicated malignant PDM or metastatic malignant melanoma. The clinical and instrumental evaluation of the patient did not reveal any other primary tumour, suggesting the primitive nature of the lesion. The absence of an epithelial component argued for a histological diagnosis of PDM. Subsequently, the patient underwent a wide surgical excision with sentinel node biopsy, which was positive for metastatic melanoma. Finally, the mutational status was studied in the main genes that regulate proliferation, apoptosis and cellular senescence. No pathogenetic mutations in CDKN2A, BRAF, NRAS, KRAS, cKIT, TP53 and PTEN genes were observed. This suggests that alternative pathways and low-frequency alterations may be involved. Conclusions: The differential diagnosis between PDM and isolated metastatic melanoma depends on the negativity of imaging studies and clinical findings for other primary lesions. This distinction is important because 5-year survival rates in such cases are higher than in metastatic cases (80-100 vs. 5-20%, respectively.

    Although credit is given to Sir William Gull for highlighting the clinical picture of subarachnoid hemorrhage in 1859, we discuss a case presented by Mr. Egerton A. Jennings, Fellow of the Linnaean Society, published 23 years earlier in the 1836 edition of the Transactions of the Provincial Medical and Surgical Association. This case, probably the first reported in the English language of a basilar aneurysm rupture, is of medico-historical interest. Jennings provided a remarkably accurate and detailed description of the patient, who experienced coma as a result of the severity of subarachnoid hemorrhage. The detailed clinical observations on initial assessment and the description of the patient's deterioration to the time of death are a succinct representation of the natural history of this disease. The author's discussion provides evidence of a philosophy committed to medical education and progress at the time based on principles of rational observation, meticulous clinical acumen, insight into experimental physiology, and the awareness of ethical boundaries. In provincial 1836 England, similar to most of Europe, cerebral localization was elementary. Nonetheless, this case report highlights the attempt at linking structure to function by means of observation on the effects of lesioning. It provides evidence of an established thought process already in progress in England in the 19th century. It is characteristic that this thought process came from a surgical practitioner. The cultivation of practical observation in British surgical culture would allow the late 19th century surgeon scientists to match the contributions of British neurologists with landmark steps in the development and establishment of neurosurgery.

    1995-11-01

    The effects of natural and anthropogenic stress need to be separated before coral reef ecosystems can be effectively managed. In this paper, a 25 year case history of coral reefs in an urban embayment (Mamala Bay) off Honolulu, Hawaii is described and differences between natural and man-induced stress are distinguished. Mamala Bay is a 30 km long shallow coastal bay bordering the southern (leeward) shore of Oahu and the city of Honolulu in the Hawaiian Islands. During the last 25 years, this area has been hit by two magnitude 5 hurricane events (winds > 240 km/h) generating waves in excess of 7.5 m. Also during this period, two large sewer outfalls have discharged up to 90 million gallons per day (mgd) or (360 × 106 L/day) of point source pollution into the bay. Initially the discharge was raw sewage, but since 1977 it has received advanced primary treatment. Non-point source run-off from the Honolulu watershed also enters the bay on a daily basis. The results of the study show that discharge of raw sewage had a serious but highly localized impact on shallow (˜10 m) reef corals in the bay prior to 1977. After 1977, when treatment was upgraded to the advanced primary level and outfalls were extended to deep water (> 65 m), impacts to reef corals were no longer significant. No measurable effects of either point or non-point source pollution on coral calcification, growth, species composition, diversity or community structure related to pollution can now be detected. Conversely the effects of hurricane waves in 1982 and 1992 together caused major physical destruction to the reefs. In 1982, average coral cover of well-developed offshore reefs dropped from 60-75% to 5-15%. Only massive species in high relief areas survived. Today, recovery is occurring, and notwithstanding major future disturbance events, long-term biological processes should eventually return the coral ecosystems to a more mature successional stage. This case history illustrates the complex nature of

    Directory of Open Access Journals (Sweden)

    Carlos Fernandes

    Full Text Available This article discusses, through an examination of the work of the Oficina de História of the Centre for African Studies (CEA at Eduardo Mondlane University, the politics of historical production and nation-state building in post-Independence Mozambique and the ambivalent position in which CEA historians were placed within that intellectual and political context. This ambivalence is in relation to two main assumptions, which can only be understood in the specific historical context of FRELIMO's strategy for socialist construction. First, the CEA researchers were well aware of their role as critical historians and fought to exercise it at the Centre. Second, they were intellectually engaged in producing a new historical narrative of FRELIMO's liberation war and the liberated zones. This meant not only producing a counter-narrative to the colonial historiography (writing 'history from below', rescuing the 'voices' of the Mozambican people etc., but also producing a strategy to legitimise FRELIMO's hegemonic project in the post-independence period. It was in the intersection between the social production of historical knowledge and the perpetuation of FRELIMO's worldview that the historians at CEA were able to safeguard and exercise their perceived role as critical historians, opening a new form of historical inquiry in Mozambique: a history of the present, at once critical and policy-oriented. Put differently, the CEA historians were able to safeguard and exercise their critical role, not on the sensitive, controversial and dangerous terrain of writing the history of FRELIMO's liberation war and the 'liberated zones', but on the writing of the history of the present en route to socialism. As they would claim, it was not possible to understand the past unless you could understand the present. With this shift these historians were able to 'escape' from simply becoming 'trapped' by their intellectual commitment to the power elite. This was done by

    We analysed a period of the contemporary Brazilian history with the aim to discuss the inter-relationship between science, technology (S and T) and culture in a developing country, showing as a background for a case of study the history of the 'Instituto de Pesquisas Energeticas e Nucleares'. The history of Science and Technology, as a result of the human brain ability of innovate using the resources offered by nature, it is not only the description of successive findings carried out by talented men. It is a reflex of determined age of history as a consequence of accumulated knowledge connected also to human and cultural relationships, which together leads to the scientific and technological progress. In fact, the human brain and society march along together and can not be separated in this journey. In our study we recovered the initial steps of IPEN's outbreak; inserted its achievements in the context of the national policy for nuclear technology and evaluated how this policy was a reply of the governmental organizations to the worldwide situation. Finally, we spread the scientific ideas and technological findings of this institution, who has translate much of the life style and culture of our society. For this purposes, we analysed internal technical report series elaborated by several researchers and few testimonies. The Institution developed the fuel cycle technology, supplied radioisotopes for medical diagnosis and treatment purposes, generating economic resources for our country. The nuclear techniques are a relevant tool for researchers of this Institution applied for several purposes, including the assessment of the radioactivity levels in the environment, radioprotection, etc. Besides those applications, other techniques including the laser technology, the fuel cell, corrosion studies, etc, were implemented as a result of the improved capabilities and skills acquired during the almost 50 years of the Institute's existence.

    Pancontinental Mining Limited acquired exploration rights over an area in the East Alligator River Region, Northern Territory, Australia, in 1970. Subsequently, Getty Oil Development Company Limited acquired a substantial minority interest in the property. The Jabiluka deposits were discovered during the course of exploration and are currently the largest of the four major uranium deposits in the East Alligator River Region. This region at present contains 24% of the western world's reasonably assured resources of uranium. The exploration techniques employed during primary and secondary exploration on the property between 1971 and 1975 and during the delineation of the Jabiluka deposits are discussed in detail. The case history illustrates the exploration philosophy which was successfully employed on the Jabiluka property. The philosophy encompasses the following points: The need for an assessment on the limits of airborne radiometric surveys; the necessity for detection and evaluation of point source anomalies; the necessity for exploration along extensions of favourable lithologies; and the desirability of modification of exploration techniques on different types of anomalies. Some aspects of this philosophy may be useful in exploration for similar stratabound uranium deposits in other areas. (author)

    Full Text Available Abstract Introduction Smoking cessation programs are useful in helping smokers to quit, but smoking is a very difficult addiction to break and the need for novel and effective approaches to smoking cessation interventions is unquestionable. The E-cigarette is a battery-powered electronic nicotine delivery device that may help smokers to remain abstinent during their quit attempt. We report for the first time objective measures of smoking cessation in smokers who experimented with the E-cigarette. Case presentation Three Caucasian smokers (two men aged 47 and 65 years and one woman aged 38 years with a documented history of recurring relapses were able to quit and to remain abstinent for at least six months after taking up an E-cigarette. Conclusions This is the first time that objective measures of smoking cessation are reported for smokers who quit successfully after using an E-cigarette. This was accomplished in smokers who repeatedly failed in previous attempts with professional smoking cessation assistance using the usual nicotine dependence treatments and smoking cessation counselling.

    Communication of knowledge between the scientific and management communities is a difficult process complicated by the distinctive nature of professional career goals of scientists and decision-makers. This article provides a case history highlighting a collaboration between the science and management communities that resulted from a response to a 2004 hypoxia, or low dissolved oxygen, event in Long Bay, off Myrtle Beach, South Carolina. A working group of scientists and decision-makers was established at the time of the event and has continued to interact to develop a firm understanding of the drivers responsible for hypoxia formation in Long Bay. Several factors were found to be important to ensure that these collaborative efforts were productive: (1) genuine interest in collaboratively working across disciplines to examine a problem; (2) commitment by agency leadership, decision-makers, and researchers to create successful communication mechanisms; (3) respect for each others’ perspectives and an understanding how science and management are performed and that they are not mutually exclusive; (4) networking among researchers and decision-makers to ensure appropriate team members are involved in the process; (5) use of decision-maker input in the formulation of research and monitoring projects; and (6) commitment of resources for facilitation to ensure that researchers and decision-makers are communicating effectively.

  6. Actual innocence: is death different?

    Science.gov (United States)

    Acker, James R

    2009-01-01

    Supreme Court jurisprudence relies heavily on the premise that "death is different" from other criminal sanctions, and that capital cases entail commensurately demanding standards of reliability. Although invoked most frequently with respect to sentencing, both precedent and logic suggest that heightened reliability applies as well to guilt determination in capital trials. Nevertheless, recurrent and highly visible wrongful convictions in capital cases have affected public opinion, contributed to a precipitous decline in new death sentences, and led to calls for reforms designed to guard against the risk of executing innocent persons. This article examines the implications of the "death is different" doctrine for the problem of wrongful convictions in both capital and non-capital cases. It argues that innovations designed to enhance reliability in the special context of death-penalty prosecutions are important in their own right, but relevant new safeguards also should extend to criminal cases generally, where innocent people are similarly at risk and wrongful convictions are far more prevalent.

    2015-09-01

    Full Text Available We estimated the orbit of the Communication, Ocean and Meteorological Satellite (COMS, a Geostationary Earth Orbit (GEO satellite, through data from actual optical observations using telescopes at the Sobaeksan Optical Astronomy Observatory (SOAO of the Korea Astronomy and Space Science Institute (KASI, Optical Wide field Patrol (OWL at KASI, and the Chungbuk National University Observatory (CNUO from August 1, 2014, to January 13, 2015. The astrometric data of the satellite were extracted from the World Coordinate System (WCS in the obtained images, and geometrically distorted errors were corrected. To handle the optically observed data, corrections were made for the observation time, light-travel time delay, shutter speed delay, and aberration. For final product, the sequential filter within the Orbit Determination Tool Kit (ODTK was used for orbit estimation based on the results of optical observation. In addition, a comparative analysis was conducted between the precise orbit from the ephemeris of the COMS maintained by the satellite operator and the results of orbit estimation using optical observation. The orbits estimated in simulation agree with those estimated with actual optical observation data. The error in the results using optical observation data decreased with increasing number of observatories. Our results are useful for optimizing observation data for orbit estimation.

    We study how uncertainty in the reionization history of the universe affects estimates of other cosmological parameters from the Cosmic Microwave Background. We analyze WMAP7 data and synthetic Planck-quality data generated using a realistic scenario for the reionization history of the universe obtained from high-resolution numerical simulation. We perform parameter estimation using a simple sudden reionization approximation, and using the Principal Component Analysis (PCA) technique proposed by Mortonson and Hu. We reach two main conclusions: (1) Adopting a simple sudden reionization model does not introduce measurable bias into values for other parameters, indicating that detailed modeling of reionization is not necessary for the purpose of parameter estimation from future CMB data sets such as Planck. (2) PCA analysis does not allow accurate reconstruction of the actual reionization history of the universe in a realistic case

  16. Counter-Memory, Heterochronia, and “History Painting” (After Géricault: Dierk Schmidt’s SIEV-X—On a Case of Intensified Refugee Politics

    Directory of Open Access Journals (Sweden)

    Veronica Tello

    2014-06-01

    Full Text Available This essay examines the disruption of linear time in experimental forms of “history painting” as represented by Dierk Schmidt’s SIEV-X—On a Case of Intensified Refugee Politics (2001-2005. It analyses how the aesthetics of heterochronoia—multiple temporalities—play a crucial role in the development of a new understanding of the politics of “history painting.” As Schmidt’s work reveals, a radical conception of history exists outside the “singular moment,” and in dialogue with heterogenous visual cultures (news media, art history, advertising. In attempting to understand the import of Schmidt’s work, this essay considers his methodologies for creating a heterochronous mode of history painting, particularly his anachronistic engagement with the work of Theodore Géricault and the iconic history painting, The Raft of the Medusa. Unlike previous critical responses to Schmidt’s work, this paper argues that (after Géricault the artist’s use of investigative “journalistic” methodologies for SIEV-X—On a Case of Intensified Refugee Politics do not generate an aesthetics of exposé but rather an aesthetics of “fictionalization.” This aesthetic is defined by the recalibration of documentary and speculative data as a means to reconceive the landscape of the perceptual. The findings of this research demonstrate that the use of disparate fragments—or data—to visualize otherwise diminishing historical events underpins contemporary history painting’s capacity for advancing a distinct economy of affect that circumvents the limitations of the news media and its “monopoly on reality.”

    According to current guidelines, spirometry should be performed in patients suspected of chronic obstructive pulmonary disease (COPD) by the results of history taking and physical examination. However, little is known about the diagnostic value of patient history and physical examination for COPD. To review the existing evidence on the diagnostic value of history taking and physical examination in recognizing COPD in patients suspected of COPD. A systematic literature search was performed in electronic medical databases. Studies were included after using defined inclusion and exclusion criteria and judged on their methodological quality by using the Quality Assessment of Diagnostic Accuracy Studies criteria. A formal meta-analysis was not performed because all studied items of history and physical examination were investigated in only in a maximum of three studies. Six studies were included. The history items dyspnoea, wheezing, previous consultation for wheezing or cough, self-reported COPD, age and smoking and the physical examination items wheezing, forced expiratory time, laryngeal height and prolonged expiration were found to have diagnostic value for COPD. These items were studied in maximally three studies and study population studies were heterogenic. The reference test for COPD in five of the six studies concerned obstructive lung disease in general and not COPD. There is insufficient evidence to assess the value of history taking and physical examination for diagnosing COPD.

    The radiographer is often the only point of contact that a patient may have with the Medical Imaging team. Assessment of the patient by the radiographer is a role that has tacitly and historically occurred in most practice, though in this age of litigation and heavy workloads it is prudent to suggest that a formulated approach should be adopted. This may occur in undergraduate education and be developed in the postgraduate forum such that good imaging is performed and appropriate extra information reaches the radiologist that may often be lacking in the referral historical details. This case based article uses an unusual presentation of osteomyelitis to illustrate where radiographer patient assessment, communication and teamwork could have contributed to a more rapid and hence higher quality experience for one situation, and also demonstrates the difficulties of eliciting information locked in the memories of patients.

    2017-06-01

    Acute bilateral foot drop is rare and may be due to peripheral or central lesions. The purpose of this case report was to describe the differential diagnosis and recovery of a patient with low back pain (LBP) that awoke with bilateral foot drop. A 39-year-old man with a history of LBP awoke with a steppage gait pattern. Spinal imaging and tapping were negative for sinister pathologies. A subsequent history taken by the physical therapist uncovered that the patient had previously taken a narcotic and slept in a kneeling position to relieve his LBP. Strength and sensory testing revealed isolated impairments in the fibular nerve distribution, and bilateral fibular palsy was suspected and later confirmed with electrophysiological studies. Surgical fibular nerve decompression was performed, and the patient underwent physical therapy. Five months later the patient demonstrated antigravity strength and a partial return of sensation. By 17 months, his Lower Extremity Functional Scale had improved from 17/80 to 78/80, revealing a near complete recovery. The patient's history of LBP was a "red herring" that delayed the diagnosis and caused undue stress to the patient. This case stresses the importance of a thorough history and clinical examination.

  6. Impact load time histories for viscoelastic missiles

    International Nuclear Information System (INIS)

    Stoykovich, M.

    1977-01-01

    Generation of the impact load time history at the contact point between a viscoelastic missile and its targets is presented. In the past, in the case of aircraft striking containment shell structure, the impact load history was determined on the basis of actual measurements by subjecting a rigid wall to aircraft crash. The effects of elastic deformation of the target upon the impact load time history is formulated in this paper. The missile is idealized by a linear mass-spring-dashpot combination using viscoelastic models. These models can readily be processed taking into account the elastic as well as inelastic deformations of the missiles. The target is assumed to be either linearly elastic or rigid. In the case of the linearly elastic target, the normal mode theory is used to express the time-dependent displacements of the target which is simulated by lumped masses, elastic properties and dashpots in discrete parts. In the case of Maxwell viscoelastic model, the time-dependent displacements of the missile and the target are given in terms of the unknown impact load time history. This leads to an integral equation which may be solved by Laplace transformation. The normal mode theory is provided. Examples are given for bricks with viscoelastic materials as missiles against a rigid target. (Auth.)

    2009-01-01

    This study of postmenopausal women with Type 2 diabetes mellitus (T2DM) investigated (1) history of depression as a predictor of endothelium-dependent flow-mediated dilation (FMD); (2) the relative associations of single and recurrent depressive disorders with FMD; and (3) cortisol as a potential mechanism. Participants were nonsmoking, naturally postmenopausal women with T2DM with no known vascular disease. All were free of current mood disorder. On average, the 44 participants were 63 years of age, White, diabetic for 6 years, and were in adequate glycemic control. Thirty-eight percent were never depressed, 19% had experienced one disorder, and 43% had experienced recurrent disorders. History of depression was assessed with Structured Clinical Interview for Diagnostic and Statistical Manual-IV. Current depressive symptoms were measured with Center for Epidemiological Studies Depression (CESD) scale. FMD was assessed by standard procedures and calculated as percent change in brachial artery diameter from baseline. Women with history of recurrent depression showed vasoconstriction (mean=-1%), which was significantly different from women with history of single depression (mean=+6) and never depressed women (mean=+5) (Pdiabetes, and glycemic control, history of recurrent depressive disorders predicted greater likelihood of vasoconstriction (P<.05, odds ratio=4.23) but history of single depressive disorder did not. Controlling for current depressive symptoms did not account for effects of past recurrent depressive disorders. Cortisol was not related to FMD. In postmenopausal women with T2DM, recurrent depressive disorders, even in full remission, are associated with endothelial dysfunction. Potential mechanisms of the relationship between depression and endothelial dysfunction other than cortisol warrant investigation.

    Anxiety is an emotion, which stimulates sympathetic nervous outflow potentially facilitating vasovagal reflex syncope (VVS) but reports on anxiety levels in patients with VVS are sparse. We studied anxiety levels in young women (21-40 years) referred for unexplained transient loss of consciousness (TLOC), and age-matched female controls with or without past history of TLOC (≈probable VVS). Referred patients underwent head-up tilt (HUT) according to current ESC Guidelines. State and Trait Anxiety Inventory questionnaire evaluated anxiety levels plus a questionnaire explored risk factors for cardiovascular disease (CVD). Sixty-five of 91 women were diagnosed with VVS on HUT. Among 549 controls, 223 (40.6%) reported at least one episode of TLOC. State-anxiety level in patients with VVS undergoing HUT (42.4 ± 9.3) was higher compared with both controls with (38.3 ± 10.2; P < 0.01) and without past TLOC history (35.9 ± 9.8; P < 0.001). Trait anxiety in patients with VVS (42.7 ± 8.4), and controls with TLOC history (42.4 ± 8.4) was higher compared with controls without TLOC history (39.7 ± 8.5; P < 0.01). In the logistic regression using controls without TLOC as reference, both VVS diagnosis and past history of TLOC were associated with family history of CVD [odds ratio (OR) 2.4, 95% confidence interval (CI), 1.3-4.4; P = 0.007, and 2.3, 1.4-3.6; P = 0.001, respectively], and this association was independent of anxiety level. Trait anxiety and family history of CVD are increased in both young women with VVS and controls with history of TLOC. However, the height of anxiety level does not explain CVD heredity and other mechanisms may link syncope with CVD. Published on behalf of the European Society of Cardiology.

  10. Inflammatory myofibroblastic tumor of maxilla showing sarcomatous change in an edentulous site with a history of tooth extraction following periodontitis: A case report with discussion.

    Science.gov (United States)

    Biniraj, K R; Janardhanan, Mahija

    2014-05-01

    Inflammatory myofibroblastic tumor (IMT) is a rare tumor of uncertain origin with variable biological behavior ranging from reactive lesions to highly aggressive malignancy. Oral IMTs are extremely rare and only 25 cases had been reported so far. A case of IMT with sarcomatous transformation in an extraction site with a history of tooth extraction following tooth mobility of an upper left molar tooth is presented here. The tooth was extracted following a complaint of gingival swelling and mobility of tooth. Though malignant transformation in IMTs had been documented in the extra oral sites, wide search of associated literature suggests, this is the first case of oral IMT showing malignant change associated with gingiva. The case report attempts to highlight the variant possibilities of tooth mobility other than periodontitis and the importance of assessing the primary cause of such conditions.

    Lung cancer is a leading cause of cancer deaths in the world. Cigarette smoking remains a prominent risk factor, but lung cancer incidence has been increasing in never smokers. Genetic abnormalities including epidermal growth factor receptor (EGFR) mutations predominate in never smoking lung cancer patients. Furthermore, familial aggregations of patients with these mutations reflect heritable susceptibility to lung cancer. The correlation between familial cancer history and EGFR mutations in never smokers with lung cancer requires investigation. This was a retrospective case-control study that evaluated the prevalence of EGFR mutations in lung cancer patients with familial cancer history. Never smokers with lung cancer treated at a hospital in Taiwan between April 2012 and May 2014 were evaluated. Inclusion criteria were never smokers with non-small cell lung cancer (NSCLC). Exclusion criteria involved patients without records of familial cancer history or tumor genotype. This study included 246 never smokers with lung cancer. The study population mainly involved never smoking women with a mean age of 60 years, and the predominant tumor histology was adenocarcinoma. Lung cancer patients with familial cancer history had an increased prevalence of EGFR mutations compared to patients without family history [odds ratio (OR): 5.9; 95% confidence interval (CI): 3.3-10.6; Pnon-pulmonary cancers (OR: 5.0; 95% CI: 2.5-10.0; Pnever smoking lung cancer patients with familial cancer history. Moreover, a sizable proportion of never smoking cancer patients harbored these mutations. These observations have implications for the treatment of lung cancer in never smokers.

    Full Text Available While the general history of archaeology has received a growing interest lately1, these efforts still lack a common research-guiding agenda. Furthermore, most of the studies still concentrate on biographies and event history. The embedding of archaeology in the structures and conditions of its time is still a kind of terra incognita. The few well known publications (e. g. Hudson 1981; Kristiansen 1981; Patterson 1986; 1995 emphasize the gap only more. The lack of a significant amount of literature especially on the social history of archaeology is all the more surprising as the early interest in archaeology shows a clear social bias: archaeology was (and still is? a recreational activity for the educated and the well-off. While Hudson’s book in particular is very readable, it is clearly meant to provide only a very broad picture. Along with the other publications mentioned above it is now somewhat dated; the lack of recent works on this topic thus highlight the lack of interest in the social history of archaeology even more.2 However, this essay does not deal with this deplorable fact, but seeks to present some ‘hard’ data on only one, albeit important activity of early archaeological excavations, particularly those of burial mounds. Its focus is on Southern Germany and on graves from the early Iron Age.3

  17. Stowaways in the history of science: the case of simian virus 40 and clinical research on federal prisoners at the US National Institutes of Health, 1960.

    In 1960, J. Anthony Morris, a molecular biologist at the US National Institutes of Health conducted one of the only non-therapeutic clinical studies of the cancer virus SV40. Morris and his research team aimed to determine whether SV40 was a serious harm to human health, since many scientists at the time suspected that SV40 caused cancer in humans based on evidence from in vivo animal studies and experiments with human tissue. Morris found that SV40 had no significant effect but his claim has remained controversial among scientists and policymakers through the present day--both on scientific and ethical grounds. Why did Morris only conduct one clinical study on the cancer-causing potential of SV40 in healthy humans? We use the case to explain how empirical evidence and ethical imperatives are, paradoxically, often dependent on each other and mutually exclusive in clinical research, which leaves answers to scientific and ethical questions unsettled. This paper serves two goals: first, it documents a unique--and uniquely important--study of clinical research on SV40. Second, it introduces the concept of "the stowaway," which is a special type of contaminant that changes the past in the present moment. In the history of science, stowaways are misfortunes that nonetheless afford research that otherwise would have been impossible specifically by creating new pasts. This case (Morris' study) and concept (the stowaway) bring together history of science and philosophy of history for productive dialog. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Species ranges are influenced by past climate oscillations, geographical constraints, and adaptive potential to colonize novel habitats at range limits. This study used Liriodendron chinense, an important temperate Asian tree species, as a model system to evaluate the roles of biogeographic history and marginal population genetics in determining range limits. We examined the demographic history and genetic diversity of 29 L. chinense populations using both chloroplast and nuclear microsatellite loci. Significant phylogeographic structure was recovered with haplotype clusters coinciding with major mountain regions. Long-term demographical stability was suggested by mismatch distribution analyses, neutrality tests, and ecological niche models (ENM) and suggested the existence of LGM refuges within mountain regions. Differences in genetic diversity between central and marginal populations were not significant for either genomic region. However, asymmetrical gene flow was inferred from central populations to marginal populations, which could potentially limit range adaptation and expansion of L. chinense.

    Diadromous fishes - species that move across salinity gradients as part of their life repertoire - form a major part of coastal and inland fisheries. Conventional mark-recapture techniques have long been used to track their movements, but give incomplete information at best. On the other hand, otoliths (ear-stones) of fishes can provide a complete record of major life history events, as reflected both in their microstructure and elemental composition. Strontium, which substitutes for calcium in the aragonite matrix of otoliths, is a powerful tracer of salinity histories in many migratory fishes. We measured Sr and Ca with a nuclear microprobe (PIXE) and show examples (eel, Anguilla anguilla; brown trout, Salmo trutta; American shad, Alosa sapidissima) of how the technique has solved several mysteries within fisheries biology

    Part of the challenge in dealing with invasive plant species is that they seldom represent a uniform, static entity. Often, an accurate understanding of the history of plant introduction and knowledge of the real levels of genetic diversity present in species and populations of importance is lacking. Currently, the role of genetic diversity in promoting the successful establishment of invasive plants is not well defined. Genetic profiling of invasive plants should enhance our understanding of the dynamics of colonization in the invaded range. Recent advances in DNA sequencing technology have greatly facilitated the rapid and complete assessment of plant population genetics. Here, we apply our current understanding of the genetics and ecophysiology of plant invasions to recent work on Australian plant invaders from the Cucurbitaceae and Boraginaceae. The Cucurbitaceae study showed that both prickly paddy melon ( Cucumis myriocarpus ) and camel melon ( Citrullus lanatus ) were represented by only a single genotype in Australia, implying that each was probably introduced as a single introduction event. In contrast, a third invasive melon, Citrullus colocynthis , possessed a moderate level of genetic diversity in Australia and was potentially introduced to the continent at least twice. The Boraginaceae study demonstrated the value of comparing two similar congeneric species; one, Echium plantagineum , is highly invasive and genetically diverse, whereas the other, Echium vulgare , exhibits less genetic diversity and occupies a more limited ecological niche. Sequence analysis provided precise identification of invasive plant species, as well as information on genetic diversity and phylogeographic history. Improved sequencing technologies will continue to allow greater resolution of genetic relationships among invasive plant populations, thereby potentially improving our ability to predict the impact of these relationships upon future spread and better manage invaders

  2. Consequences of Predicted or Actual Asteroid Impacts

    Chapman, C. R.

    2003-12-01

    Earth impact by an asteroid could have enormous physical and environmental consequences. Impactors larger than 2 km diameter could be so destructive as to threaten civilization. Since such events greatly exceed any other natural or man-made catastrophe, much extrapolation is necessary just to understand environmental implications (e.g. sudden global cooling, tsunami magnitude, toxic effects). Responses of vital elements of the ecosystem (e.g. agriculture) and of human society to such an impact are conjectural. For instance, response to the Blackout of 2003 was restrained, but response to 9/11 terrorism was arguably exaggerated and dysfunctional; would society be fragile or robust in the face of global catastrophe? Even small impacts, or predictions of impacts (accurate or faulty), could generate disproportionate responses, especially if news media reports are hyped or inaccurate or if responsible entities (e.g. military organizations in regions of conflict) are inadequately aware of the phenomenology of small impacts. Asteroid impact is the one geophysical hazard of high potential consequence with which we, fortunately, have essentially no historical experience. It is thus important that decision makers familiarize themselves with the hazard and that society (perhaps using a formal procedure, like a National Academy of Sciences study) evaluate the priority of addressing the hazard by (a) further telescopic searches for dangerous but still-undiscovered asteroids and (b) development of mitigation strategies (including deflection of an oncoming asteroid and on- Earth civil defense). I exemplify these issues by discussing several representative cases that span the range of parameters. Many of the specific physical consequences of impact involve effects like those of other geophysical disasters (flood, fire, earthquake, etc.), but the psychological and sociological aspects of predicted and actual impacts are distinctive. Standard economic cost/benefit analyses may not

  7. Library catalogues as resources for book history: case study of Novosel’s bookstore catalogue in Zagreb (1794 - 1825

    Full Text Available The aim of the paper is to analyze the book catalogue of Novosel’s bookstore, which operated in Zagreb from 1794 to 1825, and investigate the history of books and writing in Zagreb at the turn of the 19th century. The catalogue we analyzed is believed to have been published in 1801. Bearing in mind that the market-based economy started to develop in the late 18th century, it can be stipulated that Novosel and his staff and successors based the offer in their bookstore on market analysis, i.e. their readers’ needs. The increase in offer has sparked off new advertising techniques, i.e. printing of catalogues. It follows that their book catalogue reflects the image of the cultural and intellectual status and needs of readers in those times. The paper provides a short overview of book trade in the late 18th century Zagreb and of bookstore advertisements published both in books and individually, as well as a short overview of Novosel’s bookstore business. In the analysis we partly use the methodology introduced by Robert Darnton, the so-called Darnton’s circle, which takes a holistic view of the history of books taking into consideration all stages a book needs to go through - from the author, publisher, printer, bookstores, to readers, including the author him/herself as a reader. Every element is considered in relation to other elements in the circle, and in connection with external factors such as the economic and social environment, and political and intellectual influences. The books presented in the catalogue have been analyzed using different criteria: language, genre and country where they were printed. Books printed in Croatia and those written in Croatian have been given priority. In the catalogue analysis we used the database Skupni katalog hrvatskih knjižnica (joint Croatian library catalogue in order to reconstruct the printing year and printing shops that have not been listed in the catalogues. Using this methodology, we partly

    2010-01-01

    The actual nuclear R and D issues require new technologies and continuous progress in order to find adequate and effective solutions in sustained and increasing energy demand. The current tendency in energy consumption and occurring of large consumers, especially from Asian countries, imposes finding new means for energy clean, large scale and sustained production. NPPs reliability and availability were permanently monitored and improved; in the mean time the safety of the nuclear energy production was under surveillance. Corresponding development of the new technologies and discovery of improved materials and adequate technological processes offers the possibilities for appropriate implementation and use of them in the NPPs systems configuration and functioning/operation. The modern technologies and scientific discoveries, also the international cooperation, offer the opportunities to brake the actual barriers in order to cumulate and use advanced energy production processes in finding new energy sources and to build improved, reliable and safety power plants. The monitoring systems, intelligent sensors and intelligent SSCs, nanotechnologies and and modern and intelligent materials constitute the main reasons in improvement of the NPPs systems configuration and processes. The paper presents: - The state of the art in the level of actual and useful technologies for nuclear power systems development; - The actual technological limits that need to be over passed for NPPs systems improvements; - The main systems that need improvement and reconfiguration for actual NPPs development and increase in efficient operation, appropriate availability and total safety; - The actual energy production issues; - The key arguments in sustaining the R and D new NPPs systems development; - Future trends in NPPs development; - The limitations in industrial processes knowledge and use. Appropriate R and D in the field of NPPs systems has a specific characteristic that is highlighted in

  11. Potential pitfalls of reconstructing deep time evolutionary history with only extant data, a case study using the canidae (mammalia, carnivora).

    Reconstructing evolutionary patterns and their underlying processes is a central goal in biology. Yet many analyses of deep evolutionary histories assume that data from the fossil record is too incomplete to include, and rely solely on databases of extant taxa. Excluding fossil taxa assumes that character state distributions across living taxa are faithful representations of a clade's entire evolutionary history. Many factors can make this assumption problematic. Fossil taxa do not simply lead-up to extant taxa; they represent now-extinct lineages that can substantially impact interpretations of character evolution for extant groups. Here, we analyze body mass data for extant and fossil canids (dogs, foxes, and relatives) for changes in mean and variance through time. AIC-based model selection recovered distinct models for each of eight canid subgroups. We compared model fit of parameter estimates for (1) extant data alone and (2) extant and fossil data, demonstrating that the latter performs significantly better. Moreover, extant-only analyses result in unrealistically low estimates of ancestral mass. Although fossil data are not always available, reconstructions of deep-time organismal evolution in the absence of deep-time data can be highly inaccurate, and we argue that every effort should be made to include fossil data in macroevolutionary studies. © 2013 The Authors.

  12. Narrative and evidence. How can case studies from the history of science support claims in the philosophy of science?

    Science.gov (United States)

    Kinzel, Katherina

    2015-02-01

    A common method for warranting the historical adequacy of philosophical claims is that of relying on historical case studies. This paper addresses the question as to what evidential support historical case studies can provide to philosophical claims and doctrines. It argues that in order to assess the evidential functions of historical case studies, we first need to understand the methodology involved in producing them. To this end, an account of historical reconstruction that emphasizes the narrative character of historical accounts and the theory-laden character of historical facts is introduced. The main conclusion of this paper is that historical case studies are able to provide philosophical claims with some evidential support, but that, due to theory-ladenness, their evidential import is restricted.

    2014-06-01

    This article presents the history of one until now unknown case of C.G. Jung: Maggy Reichstein. Born in Indonesia in 1894 in a very aristocratic family, she brought her sister to Zurich to be treated by Jung in 1919, and later she herself was in analysis with him. Jung used her case as example in his lecture in 1937 on the realities of practical psychotherapy, relating it to the process of transference and countertransference. Jung deepened his studies in Eastern psychology after a series of dreams she had, which culminated in the Yoga Kundalini Seminars. She was also the case presented in his article of 1951 on the concept of synchronicity. Jung wrote that her case, concerning synchronicity, remained unique in his experience. Jung also published some of her mandalas. He considered her able to understand his ideas in depth. Reichstein was for Jung an important case, which challenged and triggered his interests in different subjects. © 2014, The Society of Analytical Psychology.

    2017-01-01

    Full Text Available Students in present-day Greek schools are taught History as a biography of the Greek nation from the Mycenaean times to the present. Over the course of three millennia, the Greek nation has experienced three periods of cultural flourishing and political autonomy: (i the period of Antiquity (from the times of legendary King Agamemnon to those of Alexander the Great, (ii the Byzantine period (from Justinian’s ascension in the 6th century to the Fall of Constantinople in 1453, and (iii the modern era (from the War of Independence in 1821 to the present day. However, in this article we argue that in the 19th century the history taught in Greek schools differed substantially from the tripartite schema described above. In support of our thesis, we examine the most popular school textbook of the 19th century, O Gerostathis, by Leon Melas. In the Gerostathis, the history of the Greek nation is identified with that of Classical Greece (i.e. from the 6th century BC to the 4th century BC, which is held up as an exemplary era worthy of emulation. In contrast, the rise of Macedon under Philip II signals the cultural decline of the Greeks and the loss of their political autonomy, which was not regained for two millennia, until the 1821 national revolution. In that period, the Greek nation ceased not to exist, but survived as a subjugate of the Macedonians, the Romans, and finally the Ottomans. The Byzantine, on the other hand, is described as an unremarkable period of decadence that is only worth mentioning in relation to its final period, that of the Palaeologus dynasty, which bestowed upon the Greeks a legacy of resistance against the Ottomans. We argue that the above reading of the Greek past owed much to the Enlightenment, which as an intellectual movement still exerted a powerful influence (albeit to a gradually diminishing degree on Greek intellectuals up to the latter third of the 19th century.

    Drought may become one of the greatest challenges for cereal production under future warming scenarios, and its impact on insect pest outbreaks is still controversial. To address this issue, life-history responses of the English grain aphid, Sitobion avenae (Fabricius), from three areas of different drought levels were compared under three water treatments. Significant differences were identified in developmental time, fecundity and adult weight among S. avenae clones from moist, semiarid and arid areas under all the three water treatments. Semiarid and arid area clones tended to have higher heritability for test life-history traits than moist area clones. We identified significant selection of water-deficit on the developmental time of 1st instar nymphs and adult weight for both semiarid and arid area clones. The impact of intermediate and severe water-stress on S. avenae's fitness was neutral and negative (e.g., decreased fecundity and weight), respectively. Compared with arid-area clones, moist- and semiarid-area clones showed higher extents of adaptation to the water-deficit level of their respective source environment. Adult weight was identified as a good indicator for S. avenae's adaptation potential under different water-stress conditions. After their exposure to intermediate water-deficit stress for only five generations, adult weight and fecundity tended to decrease for moist- and semiarid-area clones, but increase for arid-area clones. It is evident from our study that S. avenae clones from moist, semiarid and arid areas have diverged under different water-deficit stress, and such divergence could have a genetic basis. The impact of drought on S. avenae's fitness showed a water-level dependent pattern. Clones of S. avenae were more likely to become adapted to intermediate water-deficit stress than severe water-deficit stress. After continuous water-deficit stress of only five generations, the adaptation potential of S. avenae tended to decrease for moist

    Primary angiosarcoma of the bone (PAB) is a rare and fatal high-grade malignant vascular bone tumor. We report a rare case of multicentric PAB mimicking bone metastasis in a 59-year-old female patient with a history of sigmoid colon cancer. This patient complained of lower back and pelvic pain and presented with multiple osteolytic bone lesions on plain radiography and pelvic computed tomography. First, bone metastasis of sigmoid colon cancer was suspected. However, on the 18 F-fluorodeoxyglucose ( 18 F-FDG) positron emission tomography/computed tomography (PET/CT) scan, the patient presented unusual multiple hypermetabolic osteolytic bone lesions involving contiguous bones of the lower half of the body. After bone biopsy, these lesions were confirmed to be multicentric PAB. To the best of our knowledge, this is the first case report of an 18 F-FDG PET/CT scan in a patient with multicentric primary bone angiosarcoma

    Identification of exercise history patterns that are related to catastrophic scapular fracture will facilitate prevention of racehorse fatalities. To determine if exercise patterns are associated with scapular fracture in Thoroughbred (TB) and Quarter Horse (QH) racehorses. High-speed exercise histories for 65 TB and 26 QH racehorses that had a complete scapular fracture (cases) and 2 matched control racehorses were retrospectively studied. Exercise variables were created from lifetime race and official timed workout reports. Associations between exercise variables and scapular fracture were investigated using conditional logistic regression. Thoroughbreds with a scapular fracture had a greater number of workouts, events (combined works and races), and mean event distances than QHs with a scapular fracture. Quarter Horses worked less frequently and accumulated distance at a lower rate than TBs. Breed differences were not found for career race number or length, time between races or lay-up variables for horses with ≥1 lay-up. For both breeds, cases had fewer events, lower recent accumulated distance and fewer active days in training than controls; however, a subset of TB cases with >10 events since lay-up had a longer active career than controls. For QHs that had a lay-up, total and mean lay-up times were greater for cases than controls. Multivariable models revealed that odds ratios (OR) of scapular fracture were greater for TBs that had not yet raced (OR = 23.19; 95% confidence interval (CI) 3.03-177.38) and lower for QHs with more events (OR = 0.71; 95% CI 0.54-0.94). Racehorses that are in early high-speed training but behind that of their training cohort should be examined for signs of scapular stress remodelling. Quarter Horses that had a prolonged lay-up and TBs that have endured high-speed training for a longer duration than that of their training cohort also were at greater risk. © 2012 EVJ Ltd.

    McCune-Albright syndrome is a rare disorder characterized by endocrine disorders, café-au-lait spots and fibrous dysplasia of bone that occurs early in life. A series of 14 pediatric cases were followed between 1994 and 2013 by the competence center for rare endocrine diseases and constitutional bone diseases at CHU de Nancy (France). The diagnosis is based on the presence of at least two symptoms. The mean follow-up was 6 years (1-17 years). The sex ratio was six girls per boy. The incidence was 0.28 cases/million population/year. Mean age at diagnosis was 6 years. A mutation in the GNAS gene was found in 33% of patients tested. Gonadal involvement (13/14 cases), including early peripheral puberty and ovarian cysts in girls (82%) occurred on average at 4 years of age. Bone involvement (10/14 cases) appeared on average at 5 years of age and was most often multiple (80%) with fracture risk, and the skull, with a neurosensory risk. Clinical definition and methods of screening and monitoring can be improved to allow for an earlier intervention. It must be multidisciplinary and take into account the disability and quality of life of the patient. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

  2. False Positive Findings on I-131 WBS and SPECT/CT in Patients with History of Thyroid Cancer: Case Series

    2017-01-01

    Full Text Available Introduction. Although whole body scan (WBS with I-131 is a highly sensitive tool for detecting normal thyroid tissue and metastasis of differentiated thyroid cancer (DTC, it is not specific. Additional information, provided by single photon emission computed tomography combined with X-ray computed tomography (SPECT/CT and by the serum thyroglobulin level, is extremely useful for the interpretation of findings. Case Presentation. We report four cases of false positive WBS in patients with DTC: ovarian uptake corresponding to an endometrioma, scrotal uptake due to a spermatocele, rib-cage uptake due to an old fracture, and hepatic and renal uptake secondary to a granuloma and simple cyst, respectively. Conclusions. Trapping, organification, and storage of iodine are more prominent in thyroid tissue but not specific. Physiologic sodium-iodine symporter expression in other tissues explains some, but not all, of the WBS false positive cases. Other proposed etiologies are accumulation of radioiodine in inflamed organs, metabolism of radiodinated thyroid hormone, presence of radioiodine in body fluids, and contamination. In our cases nonthyroidal pathologies were suspected since the imaging findings were not corroborated by an elevated thyroglobulin level, which is considered a reliable tumor marker for most well-differentiated thyroid cancers. Clinicians should be aware of the potential pitfalls of WBS in DTC to avoid incorrect management.

    Conclusion: The importance of tuberculosis (TB in the development of aspergillosis, even after treatment, has been highlighted by multiple studies. Microbiological and molecular evaluation are needed to detect PA quickly and accurately. The WHO reported about 8.8 million new cases of TB in 2010. Therefore, it is essential to focus more on monitoring of diagnosis and treatment of PA.

  10. Bohmian histories and decoherent histories

    Hartle, James B.

    2004-01-01

    The predictions of the Bohmian and the decoherent (or consistent) histories formulations of the quantum mechanics of a closed system are compared for histories--sequences of alternatives at a series of times. For certain kinds of histories, Bohmian mechanics and decoherent histories may both be formulated in the same mathematical framework within which they can be compared. In that framework, Bohmian mechanics and decoherent histories represent a given history by different operators. Their predictions for the probabilities of histories of a closed system therefore generally differ. However, in an idealized model of measurement, the predictions of Bohmian mechanics and decoherent histories coincide for the probabilities of records of measurement outcomes. The formulations are thus difficult to distinguish experimentally. They may differ in their accounts of the past history of the Universe in quantum cosmology

    2012-08-01

    The aim of this study was first to describe the natural history of Buerger's disease (BD) and then to discuss a clinical approach to this disease based on multivariate analysis. One hundred eight patients who corresponded with Shionoya's criteria were selected from 2000 to 2007 for this study. Major amputation was considered the ultimate adverse event. Survival analyses were performed by Kaplan-Meier curves. Independent variables including gender, duration of smoking, number of cigarettes smoked per day, minor amputation events and type of treatments, were determined by multivariate Cox regression analysis. The recorded data demonstrated that BD may present in four forms, including relapsing-remitting (75%), secondary progressive (4.6%), primary progressive (14.2%) and benign BD (6.2%). Most of the amputations occurred due to relapses within the six years after diagnosis of BD. In multivariate analysis, duration of smoking of more than 20 years had a significant relationship with further major amputation among patients with BD. Smoking cessation programs with experienced psychotherapists are strongly recommended for those areas in which Buerger's disease is common. Patients who have smoked for more than 20 years should be encouraged to quit smoking, but should also be recommended for more advanced treatment for limb salvage.

  12. History and conservation of wild and cultivated plant diversity in Uganda: Forest species and banana varieties as case studies

    Directory of Open Access Journals (Sweden)

    Alan C. Hamilton

    2016-02-01

    Full Text Available The history of wild and cultivated plant diversity in Uganda is reviewed, taking forest species and bananas as examples. Palynological research into past human influences on forests is reassessed. The evidence suggests that crops were first introduced into the country at about 1000 BCE, farming communities practicing slash and burn agriculture started to significantly influence the floristic composition of forests during the 1st millennium BCE and there was a major episode of forest reduction at about 1000 CE related to socio-economic change. Bananas were probably introduced in the early centuries CE. The colonial era from 1894 saw the introduction of new concepts of land ownership and the establishment of forest reserves and agricultural stations. Forests and banana diversity are currently under threat, Uganda having a very high rate of deforestation and endemic banana varieties proving susceptible to introduced pests and diseases. It is suggested that, under these circumstances, conservationists take an opportunistic approach to field engagement, making use of favourable local conditions as they arise. Partnerships should be sought with elements of society concerned with sustainable use, provision of ecosystem services and cultural survival to widen the social base of plant conservation. International organisations involved in conservation of plant genetic resources and wild plant species should collaborate with one another to develop the conceptual basis of plant conservation, to make it more relevant to countries like Uganda.

    Tracking raw material back to its extraction source is a crucial step for archaeologists when trying to deduce migration patterns and trade contacts in (pre-)history. Regarding stone artefacts, the main rock types encountered in the archaeological record of Belgium are hypersiliceous rocks. This is a newly introduced category of rock types comprising those rocks made of at least 90% silica. These are strongly silicified quartz sands or sedimentary quartzites, siliceous rocks of chemical and biochemical origin (e.g. flint), very pure metamorphic quartzites and siliceous volcanic rocks (e.g. obsidian). To be able to distinguish between different extraction sources, ongoing research was started to locate possible extraction sources of hypersiliceous rocks and to characterize rocks collected from these sources. Characterization of these hypersiliceous rocks is executed with the aid of optical polarizing microscopy, optical cold cathodoluminescence and scanning-electron microscopy combined with energy-dispersive x-ray spectrometry and with back-scatter electron imaging. In this paper, we focus on various sedimentary quartzites of Paleogene stratigraphical level. (paper)

    2012-01-01

    Objective: Safety issues in magnetic resonance imaging (MRI) are important, especially in fetal MRI. However, since basic data with respect of the effective exposure time in fetal MRI are not available, this study aimed to determine the actual imaging time during a fetal MRI study. Methods: 100 fetal MRI studies of singleton pregnancies performed on a 1.5 T system were analysed with respect to study duration (from starting the survey scan until the end of study), the number of sequences acquired, and the actual imaging time, which was calculated by adding up scan time of each sequence. Furthermore, each sequence type was analysed regarding the number of acquisitions, specific absorption rates (SAR), and duration. Results: Mean study duration was 34.6 min (range: 14–58 min; standard deviation (SD): 9.7 min), the average number of sequences acquired was 26.6 (range: 11–44, SD: 6.6). Actual scan time averaged 11.4 min (range: 4–19 min, SD: 4.0 min). Ultrafast T2-weighted and steady-state free-precession sequences accounted for 62.3% of actual scan time, and were distributed over the whole duration of the study. Conclusion: Actual imaging time only accounts for 33% of total study time and is not continuous. The remaining time is consumed by the preparation phases of the scanner, and is spent with planning sequences and the eventual repositioning of the coil and/or pregnant woman. These data may help to more accurately estimate the exposure to radiofrequency deposition and noise during fetal MRI studies.

    Peripheral primitive neuroectodermal tumors of the urinary bladder are rare and tend to occur in an older age group than do their counterparts in bones and soft tissue. We report a case of peripheral primitive neuroectodermal tumor of the urinary bladder in a 67-year-old woman of Arab origin. She had undergone transurethral resection followed by chemotherapy because of pulmonary metastasized muscle-invasive squamous cell carcinoma of the bladder in 2005. One year later, she first presented with a history of repeated hematuria in our institution. Performing cystoscopy any tumor could be detected. Control cystoscopy two months later showed a tumor mass of 3 cm in diameter at another location than described for the first tumor. After perforating by transurethral resection partial bladder resection had to be done. Tissue specimen after pathological analysis revealed a peripheral primitive neuroectodermal tumor with tumor cells reactive to cluster of differentiation 99, neuron-specific enolase and S100 protein and stained negative for other markers such as cytokeratins, epithelial membrane antigen, desmin, smooth muscle actin, chromogranin and leucocyte common antigen. Staging computerized tomography was especially free from any hint on organ metastasis, but the patient died due to a cardiac problem only a few months later. To the best of our knowledge, we report the eighth case of bladder peripheral primitive neuroectodermal tumors in literature and the first concerning an Arab patient. It is also the first presentation of a peripheral primitive neuroectodermal tumor patient with a history of squamous cell carcinoma of the bladder. As in other cases, expression of single-chain-type 1 glycoprotein and neural markers was positive and the disease was at an advanced stage at the time of diagnosis.

    Full Text Available Heo Joon is one of the best-known physicians of the Chosun Dynasty, the last imperial dynasty (1392~1910 of Korea. He had served King Seonjo during his practice, and has produced many publications on medicine. Then, how did he actually treat the patients? So far, other than the case when he treated Gwanghaegun’s smallpox, it is not clearly known how and when he attended and treated the ill. In his most famous book, the Treasured Mirror of Eastern Medicine (TMEM, he details the physiopathological mechanisms, diagnoses, treatments or prescriptions, and treatment cases, however, it is not clear if they’re from his own clinical experiences. Nevertheless, based on the written method, the original information is reconstituted according to its respective editors of the TMEM, a particular case being included may be considered as an agreement and acceptance of an actual treatment executed. This research analyzes what type of medicinal theory that the main writer Heo Joon employed in his real treatments, as well as how he diagnosed and treated diseases. After analyzing the complete series of the TMEM, we found a total of 301 clinical cases. Here, one may wonder, why does the Section of Inner and External Bodily Elements, that deal with diseases and the structure of the body, have far outnumber cases than the Section of Miscellaneous Disorders? Why does the TMEM introduce the various types of disease experiences and treatment cases, medical cases, simple treatments, nurturing life, materia medica, and also include supernatural phenomena? Why does the TMEM include the experiences and cases from the book published in the Song (宋, Jin (金, Yuan (元 dynasty of China, moreover in the Ming (明 Dynasty of its time. These questions can be answered to the extent that Heo Joon and the others who participated in completing the book sought to justify the new clinical medicine practices, and because it had to be acceptable to the Confucius beliefs which

    Hyperthyroidism seems to increase metabolic and cardiovascular risk, while the effects of sub-clinical hyperthyroidism are controversial. We evaluated metabolic and cardiovascular parameters in differentiated thyroid carcinoma (DTC) patients with suppressed thyrotropin (TSH) due to levo-thyroxine (L-T4) therapy. We studied DTC patients and, as a control group, patients with a history of surgery for non-malignant thyroid pathology. Significantly higher insulin and lower HDL-cholesterol levels were recorded in DTC subjects. In both groups, insulin levels were significantly related with body mass index (BMI) but not with age or L-T4 dosage. In DTC patients, a significant negative correlation was seen between HDL-cholesterol and BMI or L-T4 dosage. In both groups, intima-media thickness (IMT) correlated positively with age, BMI, glucose levels and systolic blood pressure. In DTC patients, increased IMT was significantly correlated with glycated hemoglobin (HbA1c), cholesterol and triglycerides. In DTC patients, C-reactive protein correlated positively with insulin, insulin resistance, triglycerides and systolic blood pressure, and negatively with HDL-cholesterol. In both DTC and control subjects, fibrinogen correlated positively with age, BMI, increased IMT, HbA1c and systolic blood pressure. In DTC subjects, plasma fibrinogen concentrations correlated positively with insulin resistance, cholesterol and LDL-cholesterol, and negatively with TSH levels. Our data confirm that the favorable evolution of DTC can be impaired by a high incidence of abnormal metabolic and cardiovascular data that are, at least in part, related to L-T4 therapy. These findings underline the need for adequate L-T4 titration.

    Full Text Available Objectives: To review the cases of patients with suspected penile fracture and asses erectile and sexological outcomes. Materials and methods: from 1987 to 2013 presented to the Urology Clinic of Trieste and at the AIED of Pordenone a total of 41 cases that were divided into two groups according to the timing of treatment: 18 patients with anamnestic diagnosis of penile fracture treated nonimmediately and 23 patients treated immediately after the trauma. For all patients we evaluated the type of treatment adopted, the occurrence of complications and reoperations and the follow-up. The erectile function was also evaluated through the IIEF, as well as the psychological impact of the trauma on social and sex life, using a psycho- sexological questionnaire. Results: Among patients treated immediately after the trauma 14 were subjected to surgery. About a year after surgery, penile curvature was reported in 1 patient, pain in 3 patients, urinary disorders in 1 patient, while none reported erectile dysfunction (ED. Out of these, only 3 patients underwent reoperation. Among those treated conservatively 1 patient reported curvature, 1 patient reported pain and none reported ED. Among patients who were admitted at a later date, 14 reported curvature and 4 reported pain whereas urinary disorders were reported in 1 and ED in 4 patients. From a psychological point of view, the trauma caused in most cases a fear of new trauma and of repercussions on erectile function and sensitivity. Conclusions: The diagnosis is mainly clinical; however, radiological investigation is essential to confirm the diagnosis, assess the site and extent of the trauma and possible urethral involvement, so as to plan the most appropriate treatment. In addition, immediate treatment leads to better long-term results, with a lower incidence of ED and penile curvature. Psychologically, penile trauma intensifies the fear of reoccurrence; it decreases, however, with the passage of time.

    While both the sciences and the humanities, as currently defined, may be too heterogeneous to be encompassed within a unified historical framework, there is good reason to believe that the history of science and the history of philologies both have much to gain by joining forces. This collaboration has already yielded striking results in the case of the history of science and humanist learning in early modern Europe. This essay argues that first, philology and at least some of the sciences (e.g., astronomy) remained intertwined in consequential ways well into the modern period in Western cultures; and second, widening the scope of inquiry to include other philological traditions in non-Western cultures offers rich possibilities for a comparative history of learned practices. The focus on practices is key; by shifting the emphasis from what is studied to how it is studied, deep commonalities emerge among disciplines--and intellectual traditions--now classified as disparate.

    Fisheries observer programs are used around the world to collect crucial information and samples that inform fisheries management. However, observer error may misidentify similar-looking shark species. This raises questions about the level of error that species misidentifications could introduce to estimates of species' life history parameters. This study addressed these questions using the Grey Reef Shark Carcharhinus amblyrhynchos as a case study. Observer misidentification rates were quantified by validating species identifications using diagnostic photographs taken on board supplemented with DNA barcoding. Length-at-age and maturity ogive analyses were then estimated and compared with and without the misidentified individuals. Vertebrae were retained from a total of 155 sharks identified by observers as C. amblyrhynchos. However, 22 (14%) of these were sharks were misidentified by the observers and were subsequently re-identified based on photographs and/or DNA barcoding. Of the 22 individuals misidentified as C. amblyrhynchos, 16 (73%) were detected using photographs and a further 6 via genetic validation. If misidentified individuals had been included, substantial error would have been introduced to both the length-at-age and the maturity estimates. Thus validating the species identification, increased the accuracy of estimated life history parameters for C. amblyrhynchos. From the corrected sample a multi-model inference approach was used to estimate growth for C. amblyrhynchos using three candidate models. The model averaged length-at-age parameters for C. amblyrhynchos with the sexes combined were L∞ = 159 cm TL and L0 = 72 cm TL. Females mature at a greater length (l50 = 136 cm TL) and older age (A50 = 9.1 years) than males (l50 = 123 cm TL; A50 = 5.9 years). The inclusion of techniques to reduce misidentification in observer programs will improve the results of life history studies and ultimately improve management through the use of more accurate data

    Working within the HPO (History Projection Operator) Consistent Histories formalism, we follow the work of Savvidou on (scalar) field theory [J. Math. Phys. 43, 3053 (2002)] and that of Savvidou and Anastopoulos on (first-class) constrained systems [Class. Quantum Gravt. 17, 2463 (2000)] to write a histories theory (both classical and quantum) of Electromagnetism. We focus particularly on the foliation-dependence of the histories phase space/Hilbert space and the action thereon of the two Poincare groups that arise in histories field theory. We quantize in the spirit of the Dirac scheme for constrained systems

    Carcinoma showing thymus-like elements (CASTLE) is a rare malignant tumor of the thyroid or adjacent neck soft tissues, whose histogenesis is still debated. It may resemble other primary or metastatic poorly differentiated tumors histologically and the differential diagnosis is crucial for CASTLE has a better prognosis. However, CASTLE as a second primary tumor has not been reported in the literature. We report three cases of thyroid CASTLE, including a unique tumor following breast-conserving surgery for early-stage breast invasive carcinoma. There were two female and one male. All three tumors were located in the right lobe of the thyroid, and one tumor showed extension into the surrounding soft tissue. Histologically, all tumors showed expansive growth and consisted of cords, nests or sheets of epithelial cells divided into irregularly shaped lobules by fibrous connective tissue with lymphoplasmacytic infiltration. Focal squamous differentiation resembling Hassall's corpuscles were observed. All cases stained positively for CD5, CD117, high molecular weight cytokeratin, cytokeratin, P63, carcinoembryonic antigen and epithelial membrane antigen. Positive staining for Bcl-2 in two cases and chromogranin A in one case was noted. Ki-67 expression ranged from 15 to 25%. Thyroid transcription factor and CD3 were negative. There was no evidence of recurrent or metastatic disease at following surgery. These features demonstrated CASTLE may arise from branchial pouch remnants, the thyroid solid cell nests. CASTLE is a rare entity, awareness of its occurrence as a second primary tumor is important to avoid overtreatment because it is associated with a favorable prognosis.

    Full Text Available Background: An uncommon but well-established complication of cranial irradiation is secondary neoplasm. This case presentation documents a radiation-induced malignant glioma 55 years after being diagnosed with “cerebral sarcoma,” now defined as atypical meningioma. This not only represents the longest reported latency period for a patient initially receiving over 30 Gy, but also provides a valuable historical perspective of neuro-oncology. Clinical Presentation: A 58-year-old female presenting with progressive left-sided upper and lower extremity weakness with a past medical history significant for “cerebral sarcoma” was diagnosed with glioblastoma multiforme. This patient had previously been treated with resection and adjuvant radiation therapy via a 280-kVP orthovoltage machine and received 3,390 rad to the posterior three-quarters of the skull for “cerebral sarcoma.” Conclusion: A comprehensive investigation of the past medical history helped uncover a mysterious pediatric diagnosis, helped drive the management 5 decades later, and serves as a reminder that seemingly safe interventions may still cause harm.

    The repurposing of electronic health records (EHRs) can improve clinical and genetic research for rare diseases. However, significant information in rare disease EHRs is embedded in the narrative reports, which contain many negated clinical signs and family medical history. This paper presents a method to detect family history and negation in narrative reports and evaluates its impact on selecting populations from a clinical data warehouse (CDW). We developed a pipeline to process 1.6 million reports from multiple sources. This pipeline is part of the load process of the Necker Hospital CDW. We identified patients with "Lupus and diarrhea," "Crohn's and diabetes," and "NPHP1" from the CDW. The overall precision, recall, specificity, and F-measure were 0.85, 0.98, 0.93, and 0.91, respectively. The proposed method generates a highly accurate identification of cases from a CDW of rare disease EHRs. © The Author 2016.

  9. Evidence for Complex P-T-t Histories in Subduction Zone Rocks: A Case Study from Syros, Greece

    Numerical models predict that material can move freely at the interface between the subducting slab and the overlying mantle wedge (mélange zone) independent of the motion of the subducting slab (i.e. Cloos 1982, Gerya et al. 2002). This is possible because the mélange zone consists of rigid blocks of metagabbroic and metabasic material suspended in a strongly sheared matrix of serpentinite, talc, and chlorite. The implication of this is that blocks of subducted material exposed in outcrops at the earth's surface could experience complex Pressure-Temperature-time (P-T-t) paths due to the cycling and recycling of subducted material within the mélange zone. Such behavior can affect the expulsion and retention of fluid during metamorphism and thus affect elemental cycles, geodynamics, mineral phase equilibra and mass transport of materials in the mélange zone depending on the physical properties and location of the blocks. The island of Syros, Greece preserves rocks that experienced blueschist-eclogite grade metamorphism during the subduction of the Pindos Oceanic Unit and thus provides a natural laboratory for investigating the evolution of subducted lithologies. Complex compositional zoning in a garnet-bearing quartz mica schist indicates that garnet crystals grew in two distinct stages. The presence of distinct cores and rims is interpreted as the result of a complex P-T-t history. Through the use of thermodynamic modeling, we calculate that the core of the garnet equilibrated at 485oC and 22.5 kbars. The edge of the first growth zone is predicted to stop growing at approximately 530oC and 20.5 kbars. We calculate that the rim began to grow at 21.7 kbars and 560oC and that the end of garnet growth occurred at approximately 16 kbars and 500oC. Sm/Nd garnet geochronology was used to date the cores of the garnets at 47 ± 3 Ma, with preliminary results suggesting that the rims grew at a significantly younger age. These data support the hypothesis that the cycling

    Full Text Available Abstract Background Hamate hook fracture is a common fracture in golfers and others who play sports that involve rackets or sticks such as tennis or hockey. This patient had a previous hamate fracture in the opposing wrist along with potential features of hamate bipartite. Case presentation A 19 year old male presented with a complaint of right wrist pain on the ulnar side of the wrist with no apparent mechanism of injury. The pain came on gradually one week before being seen in the office and he reported no prior care for the complaint. His history includes traumatic left hamate hook fracture with surgical excision. Conclusion The patient was found to have marked tenderness over the hamate and with a prior fracture to the other wrist, computed tomography of the wrist was ordered revealing a fracture to the hamate hook in the right wrist. He was referred for surgical evaluation and the hook of the hamate was excised. Post-surgically, the patient was able to return to normal activity within eight weeks. This case is indicative of fracture rather than hamate bipartite. This fracture should be considered in a case of ulnar sided wrist pain where marked tenderness is noted over the hamate, especially after participation in club or racket sports.

    The introduction of organized cervical cancer (CC) screening programs has drastically reduced the prevalence of CC. However the incidence is still too high, especially among elderly women. All guidelines strongly recommend a regular Papanicolaou (Pap) testing for young and middle-aged patients. On the other hand, many international professional societies no longer advise screening in women who have undergone hysterectomy, and in women aged 65 years and above, who have a previous history of regular Pap smears. Here we report the case of poorly differentiated CC, involving the pelvic lymph nodes and urinary bladder, occurring in a 79-year-old woman who regularly underwent Pap tests, with no reported cytological abnormalities. In this very rare case, the CC cells, as well as cells from metastatic lymph nodes and cells from urinary specimens, molecularly showed human papilloma virus (HPV)-53. With the limitations of a single case, this report brings important information to prevent CC in elderly patients: the utility of molecular tests to increase sensitivity of Pap smears in postmenopausal women; the importance of HPV-53 as one of the four "emergent" genotypes having a possible role in oncogenesis; and the presence of HPV-53 in lymph node metastases from cervical carcinoma, which would support the role of this virus in the maintenance of malignant status.

    Emphasis is placed on the evaluation of corrosion failures of copper and machineable brass alloys during service. Typical corrosion failures of the presented case histories mainly focussed on stress corrosion cracking and dezincification that acted as the major degradation mechanisms in components used in piping and water supply systems. SEM assessment, coupled with EDS spectroscopy, revealed the main cracking modes together with the root-source(s) that are responsible for the damage initiation and evolution. In addition, fracture surface observations contributed to the identification of the incurred fracture mechanisms and potential environmental issues that stimulated crack initiation and propagation. Very frequently, the detection of chlorides among the corrosion products served as a suggestive evidence of the influence of working environment on passive layer destabilisation and metal dissolution.

    Full Text Available Cardiac myxomas are the most frequently encountered benign cardiac tumors in adult groups. Patients with myxoma may suffer from variety of clinical features. A patient who had suffered from stroke a yearago came to our hospital with a chest pain complaint. In the echocardiography of the patient suffering from acute coronary syndrome, left ventricular disfunction and left atrial mass was determined. In the coronary angiography, LAD and Cx critical stenosis, and an abnormal feeding artery which roots from Cxperformed was observed. LIMA-AD, Ao-RCA bypass and mass exision withleft atriotomy was made. Cardiac tumor embolism which makes up a rare cause of cerebral embolies should be considered especiallyin patients with sinus rhythm. In the coronary angiography the feeding artery of the myxoma was shown. A patient who has underwent coronary bypass operation and left atrial myxoma exision has beenpresented as a case.

    Full Text Available Declension of the terms Reduce, Reuse, Recycle in relation to urban development, nowadays offers the opportunity for a new generation of spaces and architectures that interpret construction – dilapidated, neglected worn out or abandoned – as a real resource and hence value. Renewal activities concern new programmes and projects for rethinking uses, meanings and values which existing construction – from the individual building to the neighbourhood – contain and which can change. Indeed, nowadays, a series of design approaches can be acknowledged and consolidated; European best practices which reinterpret renewal projects – including energy regeneration –, not limiting themselves to technological and typological updating of buildings, but also to urban and social implications. The paper proposes to document these advanced reference scenarios, flanked by educational experimentation and research being performed in case studies developed together with Rome’s local building authority (ATER.

    2018-03-01

    This article examines the development and use of rotation therapy in the emerging field of psychiatry at the beginning of the 19th century, and the cross-fertilization between British, Irish, German, French and other European proponents of 'Cox's Swing'. Its short-lived popularity is linked to prevalent Enlightenment thought, to the development of an industrial and technological society, to the modern medical theories of irritability, and to the new practice of 'moral management' of the mentally ill. Case studies documenting the use of the Swing are considered from these perspectives, and are compared with contemporary public reactions in the form of publications in newspapers and of a literary text by German Romantic author Ludwig Achim von Arnim.

    Secondary sclerosing cholangitis in critically ill patients (SSC-CIP) is an important differential diagnosis in patients presenting with cholestasis and PSC-like cholangiographic changes in endoscopic retrograde cholangiography (ERC). As a relatively newly described entity, SSC-CIP is still underdiagnosed, and the diagnosis is often delayed. The present study aims to improve the early detection of SSC-CIP and the identification of its complications.A total of 2633 records of patients who underwent or were listed for orthotopic liver transplantation at the University Hospital Charité, Berlin, were analyzed retrospectively. The clinical presentation and outcome (mean follow-up 62.7 months) of the 16 identified SSC-CIP cases were reviewed.Cholestasis was the first sign of SSC-CIP. GGT was the predominant enzyme of cholestasis. Hypercholesterolemia occurred in at least 75% of the patients. SSC-CIP provoked a profound weight loss (mean 18 kg) in 94% of our patients. SSC-CIP was diagnosed by ERC in all patients. The 3 different cholangiographic features detected correspond roughly to the following stages: (I) evidence of biliary casts, (II) progressive destruction of intrahepatic bile ducts, and (III) picture of pruned tree. Biliary cast formation is a hallmark of SSC-CIP and was seen in 87% of our cases. In 75% of the patients, the clinical course was complicated by cholangiosepsis, cholangitic liver abscesses, acalculous cholecystitis, or gallbladder perforation. SSC-CIP was associated with worse prognosis; transplant-free survival was ∼40 months (mean).Because of its high rate of serious complications and unfavorable prognosis, it is imperative to diagnose SSC-CIP early and to differentiate SSC-CIP from other types of sclerosing cholangitis. Specific characteristics enable identification of SSC-CIP. Early cooperation with a transplant center and special attention to biliary complications are required after diagnosis of SSC-CIP.

    The need for developing effective telehealth tools for dysphagia management is high not only for people who live in rural areas, but also for individuals with mobility/access limitations. We aimed to develop an electronic case History Tool/form (thereafter, e-HiT) for dysphagia, and compare its effectiveness with its paper-based version (PBV) on completion time, completeness, independence, and patient perceptions/satisfaction. Secondarily, we examined associations between the aforementioned variables and predictor variables, such as age, cognition, and computer/internet use. Forty adults who expressed concerns with eating/swallowing participated. To compare both versions, a randomized, controlled two-period crossover design was used. In Visit 1, Group A completed the e-HiT and Group B completed the PBV. In Visit 2, Group A completed the PBV and Group B completed the e-HiT. A satisfaction survey was completed post visits. There were no statistically significant differences for completion time (p = 0.743), completeness (p = 0.486), and independence (p = 0.738). Patient perception/satisfaction was significantly higher with the e-HiT (p = 0.004). In addition, a significant association was found between completion time and age (p = 0.0063). Our results indicate that completing the e-HiT is as time efficient as completing the PBV and that both forms elicit the same amount of information with no or minimal support. Also, completion of the e-HiT yielded significantly higher satisfaction responses. This is the first study documenting the effectiveness of the e-HiT for outpatients with dysphagia, providing evidence that the first step of a swallowing assessment-case history completion-can be effectively completed via telehealth by individuals with reliable internet connection and basic computer literacy skills.

  18. Impact load time histories for viscoelastic missiles

    1977-01-01

    Generation of the impact load time history at the contact point between a viscoelastic missile and its targets is presented. In the past, in the case of aircraft striking containment shell structure, the impact load time history was determined on the basis of actual measurements by subjecting a rigid wall to aircraft crash. The effects of elastic deformation of the target upon the impact load time history is formulated in this paper. The missile is idealized by a linear mass-spring-dashpot combination using viscoelastic models. These models can readily be processed taking into account the elastic as well as inelastic deformations of the missiles. The target is assumed to be either linearly elastic or rigid. In the case of the linearly elastic target, the normal mode theory is used to express the time-dependent displacements of the target which is simulated by lumped masses, elastic properties and dashpots in discrete parts. In the case of Maxwell viscoelastic model, the time-dependent displacements of the missile and the target are given in terms of the unknown impact load time history. This leads to an integral equation which may be solved by Laplace transformation. The normal mode theory is provided. The target structure may be composed of different materials with different components. Concrete and steel structural components have inherently different viscous friction damping properties. Hence, the equivalent modal damping depends on the degree of participation of these components in the modal response. An approximate rule for determining damping in any vibration mode by weighting the damping of each component according to the modal energy stored in each component is considered

    Full Text Available This article makes a case in defense of oral history in the study of political science and international relations. The existing literature has scrutinized the technical aspects and appropriate use of oral material. This article focuses on the circumstances under which oral history may be an indispensable method of scholarly investigation: first, when written primary sources are not readily available; second, when an investigation targets complex and secret high-level negotiations; and third, when the main research concern is the human agent’s perspective and ideational factors. The article first addresses the issue of reliability and rigor of oral history as compared to written sources and then concentrates on the creation of Mercosur as an example of the validity of oral history under the three circumstances identified. The conclusion proposes a revival of a more historical approach to political studies.Este artículo argumenta en favor del uso de la historia oral como método de estudio de las relaciones internacionales y de las ciencias políticas. La literatura académica se ha centrado en las cuestiones más técnicas de las entrevistas y en el uso apropiado de este método. El foco innovador del articulo analiza las circunstancias en que la historia oral puede representar una herramienta indispensable para la investigación académica: primero, cuando las fuentes escritas no están disponibles; segundo, cuando se investigan negociaciones reservadas y complejas de alto nivel; tercero, cuando el interés principal de la investigación es la perspectiva del agente y los factores ideacionales. En primer lugar, el artículo discute la confiabilidad y el rigor de la historia oral en comparación con las fuentes escritas. Luego, el análisis se centra en el caso de estudio de la creación de Mercosur, usado como ejemplo de la validez de la historia oral bajo las tres circunstancias identificadas.

    OBJECTIVE Juvenile GM2 gangliosidosis is a group of inherited neurodegenerative diseases caused by deficiency of lysosomal β-hexosaminidase resulting in GM2 ganglioside accumulation in brain. The purpose of this study was to delineate the natural history of the condition and identify genotype-phenotype correlations that might be helpful in predicting the course of the disease in individual patients. METHODS A cohort of 21 patients with juvenile GM2 gangliosidosis, 15 with the Tay-Sachs variant and 6 with the Sandhoff variant, was studied prospectively in 2 centers. Our experience was compared with previously published reports on 134 patients. Information about clinical features, β-hexosaminidase enzyme activity, and mutation analysis was collected. RESULTS In our cohort of patients, the mean (±SD) age of onset of symptoms was 5.3 ± 4.1 years, with a mean follow-up time of 8.4 years. The most common symptoms at onset were gait disturbances (66.7%), incoordination (52.4%), speech problems (28.6%), and developmental delay (28.6%). The age of onset of gait disturbances was 7.1 ± 5.6 years. The mean time for progression to becoming wheelchair-bound was 6.2 ± 5.5 years. The mean age of onset of speech problems was 7.0 ± 5.6 years, with a mean time of progression to anarthria of 5.6 ± 5.3 years. Muscle wasting (10.6 ± 7.4 years), proximal weakness (11.1 ± 7.7 years), and incontinence of sphincters (14.6 ± 9.7 years) appeared later in the course of the disease. Psychiatric disturbances and neuropathy were more prevalent in patients with the Sandhoff variant than in those with the Tay-Sachs variant. However, dysphagia, sphincter incontinence, and sleep problems occurred earlier in those with the Tay-Sachs variant. Cerebellar atrophy was the most common finding on brain MRI (52.9%). The median survival time among the studied and reviewed patients was 14.5 years. The genotype-phenotype correlation revealed that in patients with the Tay-Sachs variant, the presence

    Autoimmune progesterone dermatitis (APD) is a rare autoimmune response to raised endogenous progesterone levels that occur during the luteal phase of the menstrual cycle. Cutaneous, mucosal lesions and other systemic manifestations develop cyclically during the luteal phase of the menstrual cycle when progesterone levels are elevated. APD symptoms usually start 3 - 10 days before menstruation and resolve 1 - 2 days after menstruation ceases. A 30-year-old woman presented with urticaria, petechiae and palpable pinpoint purpura lesions of the legs, forearms, neck and buttocks 1 week prior to her menses starting and 2 months after a medical abortion. She was diagnosed with allergic contact dermatitis and topical steroids were prescribed. Her skin conditions did not improve and were associated with her menstrual cycle. We performed an intradermal test using progesterone, which was positive. She was treated with oral contraceptive pills and the symptoms were resolved. This is a typical case of APD triggered by increased sensitivity to endogenous progesterone induced a few months after medical abortion.

    We introduce quantum history states and their mathematical framework, thereby reinterpreting and extending the consistent histories approach to quantum theory. Through thought experiments, we demonstrate that our formalism allows us to analyze a quantum version of history in which we reconstruct the past by observations. In particular, we can pass from measurements to inferences about ‘what happened’ in a way that is sensible and free of paradox. Our framework allows for a richer understanding of the temporal structure of quantum theory, and we construct history states that embody peculiar, non-classical correlations in time. (paper)

    For the calculation of the parasite resistance of an airplane, a knowledge of the resistance of the individual structural and accessory parts is necessary. The most reliable basis for this is given by tests with actual airplane parts at airspeeds which occur in practice. The data given here relate to the landing gear of a Siemanms-Schuckert DI airplane; the landing gear of a 'Luftfahrzeug-Gesellschaft' airplane (type Roland Dlla); landing gear of a 'Flugzeugbau Friedrichshafen' G airplane; a machine gun, and the exhaust manifold of a 269 HP engine.

    Problems of actuality of the Einstein theory of gravitation are lightened. The great Einstein theory of gravitation is shown to remain a reliable base of understanding of modern physical world pattern and its inevitable further inexhaustible precising. The main GRT difficulties are enumirated: determination of reference systems, presence of singularities in the theory, absence of consistent determination of the gravity energy, impossibility of accounting the relations between atomic, gravitational and cosmological characteristics. The attention is paid to gauge, twistor problems and to unified interaction theory. The great contribution of the soviet science in the theory of gravitation is stressed

    2009-01-01

    This case history explores how the question of agency was dealt with historically in two developing, normative orders of deviant behaviour. Examining the institutional career of the supposed adulterer, marriage swindler, and craft baker, we can trace the different observation regimes and systems of knowledge acquisition in the prison and in psychiatry, in both institutions there was talk of simulated madness; the explanations, however, were different. For the prison doctors and civil servants, the baker was a criminal; his deviant behaviour was a matter of consciously planned-out deception. For the examining psychiatrist, on the other hand, he was mentally ill and could not be held responsible for his own behaviour. The case also shows how the suspicion of simulated madness stabilized an intermediate space between the two regimes that can be seen in the incoherence of the historical sources. This conflict was never resolved; the very indecisiveness marked the defiance and agency of the historical actor that could not be clearly decided within the institutional observation regimes and their methods of recording.

    This case-based report assessed resting water content and exercise-driven water exchange within a tendon with a history of tendinopathy and compared the response to that of a healthy uninvolved tendon. Case Report. University imaging center. The participant was a 27-year-old female basketball player 39 months following knee trauma. Patellar tendinopathy developed 12 months after the injury episode and was treated with eccentric exercises. Eighteen months from the beginning of the first eccentric training bout, the participant reported full resolution of symptoms and returned to her pre-injury sport participation without symptoms. Eccentric decline squat exercise. Tendon water content obtained from magnetic resonance imaging (MRI). MRI acquired 39 months post-injury demonstrated increased resting water content of the involved tendon (involved: 91.1% vs. uninvolved: 84.6%). Immediately after the eccentric squat maneuver, water content decreased on both involved and uninvolved tendons (involved: 89.5% vs. uninvolved: 83.3%). Elevated resting water content of the involved tendon found in this report may be indicative of reduced tendon stiffness. A similar amount of water content reduction was observed on both sides following mechanical loading, suggesting that the involved tendon may respond to the eccentric exercise similarly to the uninvolved tendon. Future investigations are needed to study the relationships among tendon water exchanges, mechanical properties, patient symptoms, and tissue injuries.

  11. Increased deep sleep in a medication-free, detoxified female offender with schizophrenia, alcoholism and a history of attempted homicide: Case report

    Full Text Available Abstract Background Psychiatric sleep research has attempted to identify diagnostically sensitive and specific sleep patterns associated with particular disorders. Both schizophrenia and alcoholism are typically characterized by a severe sleep disturbance associated with decreased amounts of slow wave sleep, the physiologically significant, refreshing part of the sleep. Antisocial behaviour with severe aggression, on the contrary, has been reported to associate with increased deep sleep reflecting either specific brain pathology or a delay in the normal development of sleep patterns. The authors are not aware of previous sleep studies in patients with both schizophrenia and antisocial personality disorder. Case presentation The aim of the present case-study was to characterize the sleep architecture of a violent, medication-free and detoxified female offender with schizophrenia, alcoholism and features of antisocial personality disorder using polysomnography. The controls consisted of three healthy, age-matched women with no history of physical violence. The offender's sleep architecture was otherwise very typical for patients with schizophrenia and/or alcoholism, but an extremely high amount of deep sleep was observed in her sleep recording. Conclusions The finding strengthens the view that severe aggression is related to an abnormal sleep pattern with increased deep sleep. The authors were able to observe this phenomenon in an antisocially behaving, violent female offender with schizophrenia and alcohol dependence, the latter disorders previously reported to be associated with low levels of slow wave sleep. New studies are, however, needed to confirm and explain this preliminary finding.

This case highlights the complexity involved in establishing diagnosis when presentation is atypical. In certain cases diagnosis cannot be established based on clinical presentation or biopsy findings alone, and critical analysis of biopsy findings in context of clinical presentation is crucial to guide the clinical decision-making process.Case presentation: A 47-year-old Hispanic male with history of granulomatosis with polyangiitis (GPA in remission on azathioprine, presented with fatigue and lethargy. Physical examination was unremarkable. Laboratory data revealed elevated creatinine and otherwise normal electrolytes. Urinalysis showed numerous dysmorphic red blood cells with few red cell casts. His serologic results were all negative except anti-proteinase-3 antibody at very low titers. Kidney biopsy showed necrotizing crescentic glomerulonephritis with linear immunoglobulin G staining along the basement membrane.Conclusion: This case presented conflicting serologic and histopathologic findings. The presence of anti-proteinase-3 antibody supported diagnosis of recurrence of GPA. However, linear staining of immunoglobulin G (IgG on immunofluorescence (IF staining of renal biopsy supported anti-glomerular basement membrane (GBM disease. The treatment of anti-GBM disease and GPA both involve immunosuppression with prednisone and cyclophosphamide. However, patients with anti-GBM disease are also treated with plasmapheresis early in the disease presentation to prevent further damage. The patient with GPA, on the other hand, was shown to benefit from plasmapheresis only in the case of severe renal disease (serum creatinine level more than 5 mg/dL or

However the incidence is still too high, especially among elderly women. All guidelines strongly recommend a regular Papanicolaou (Pap testing for young and middle-aged patients. On the other hand, many international professional societies no longer advise screening in women who have undergone hysterectomy, and in women aged 65 years and above, who have a previous history of regular Pap smears. Here we report the case of poorly differentiated CC, involving the pelvic lymph nodes and urinary bladder, occurring in a 79-year-old woman who regularly underwent Pap tests, with no reported cytological abnormalities. In this very rare case, the CC cells, as well as cells from metastatic lymph nodes and cells from urinary specimens, molecularly showed human papilloma virus (HPV-53. With the limitations of a single case, this report brings important information to prevent CC in elderly patients: the utility of molecular tests to increase sensitivity of Pap smears in postmenopausal women; the importance of HPV-53 as one of the four “emergent” genotypes having a possible role in oncogenesis; and the presence of HPV-53 in lymph node metastases from cervical carcinoma, which would support the role of this virus in the maintenance of malignant status.Keywords: old women, molecular tests, cervical cancer screening, HPV-DNA test, HPV genotypingA Letter to the editor has been received and published for this articleCorrigendum for this paper has been published

  1. List of subscribers as the source of data on book history and the history of reading: case study of book subscribers' lists printed in Dalmatia in the early 19th century

    Jelena Lakuš

    2013-02-01

    Full Text Available Customer networks or lists of subscribers as a new publishing phenomenon first occurred in Dalmatia in the early 19th century. It was a model of collective funding of book, magazine and newspaper publishing, which gradually replaced the earlier system of individual patronage. It resulted in the publication of lists of subscribers that contained the names of all those who financially supported the printing of a book. The data on names of subscribers, their occupation, place of residence and number of copies ordered, which was the usual content of subscribers, lists, make them very valuable sources for research on the history of books and reading. This paper tries to show the research potential of such lists by presenting a case-study of five preserved and available subscribers' lists found in publications printed between 1835 and 1848 in the Zadar print shop of Battara brothers. The paper analyses the quantitative data on subscribers, their geographical distribution, professional profile and gender, which does not exhaust their research potential in full. The analysis has shown that despite the austere educational opportunities, high incidence of unemployment, and many other limitations, there were people who treasured the written word. The subscribers mostly came from coastal cities like Zadar, Split and Dubrovnik, which were the most important publishing and cultural centres. Even though the subscribers came from Austria, Military Border, Italy, Croatia proper and Slavonia, as well as Bosnia and Herzegovina, which was then part of the Ottoman Empire, they make up only one eight of the total number of subscribers in the corpus. The subscribers are both Roman-Catholic and Orthodox, who mostly subscribed to books printed in the Cyrillic script. The subscribers come from a wide range of professions, mostly from the church circles in Dalmatia, and the fewest of them were professors and teachers, members of the army and the police.

    Basic steps to be taken before using any cleaning method are select a responsible group and give it full responsibility; know the problem, what type of fouling, lab samples, amount of material, time and cost; sell the idea to management; maintain the cleaning equipment; and follow up each cleaning operation. These principles have been applied to advantage in the amine contractor at Taylor, a vessel 60 ft high with 78-in. OD, containing carbon steel deck trays with stainless steel caps. The original attempt to clean with wire scrapers manually involved much lost time and several crews. There was limited space in the tray vessels, design created areas difficult to clean, working conditions were unpleasant, equipment downtime was extended, labor cost was high, and the final result was not satisfactory. Chemical cleaning was substituted, preceded by a water wash. Five hours of caustic wash with a 3% solution at 170$F were followed by a water wash, an acid wash, 1-hr neutralization with a weak soda ash solution, and finally passivation to eliminate iron oxide. For the acid wash, sulfamic acid was found best, in 10% concentration for 4 hr. Cascading was most economical, but flooding has been employed sometimes at 2-1/2 times the cost, to reach all the dark corners.

  6. The history of nuclear fear

    1993-01-01

    The history of military and civilian nuclear energy is not only a matter of hard technology, politics, and economics. Our thinking about bombs and reactors is also affected by images with a curious and sometimes overwhelming power. Weird rays that can transform flesh or create monsters, the atom-powered marvels of a future uptopia, the mad scientist who plots to destroy the world: all have an influence on the way people think. Already decades before scientists had discovered how to exploit nuclear energy, a web of interconnected symbols was fully formed in the public mind. These images can be traced back to primitive imagery and, still deeper, into common human experiences, but they were often connected specifically to nuclear energy by nuclear scientists themselves. After the actual development of nuclear technology, a variety of groups used the old symbolism for their propaganda. Since nuclear energy was the most impressive case of the application of the arcane mysteries of science by modern technological authorities, it came to stand for all that people hoped, and still more what they feared, from such authorities

    A new clinicopathological concept of IgG4-related sclerosing disease affecting various organs has recently been proposed in relation to autoimmune pancreatitis. This report describes the case of IgG4-related retroperitoneal fibrosis and sclerosing cholangitis independent of autoimmune pancreatitis, which recurred after a long period of spontaneous remission. An 80-year-old Japanese man presented with obstructive jaundice owing to a hepatic hilum bile duct stricture. Coincidentally, a soft tissue mass surrounding the abdominal aorta, suggesting retroperitoneal fibrosis, was identified. Unexpectedly, spontaneous regression of obstructive jaundice together with retroperitoneal fibrosis occurred. The presence of high serum IgG4 concentrations measured later led us to consider a possible association with autoimmune pancreatitis; however, there were no clinical features confirming autoimmune pancreatitis. After a 5-year history of spontaneous clinical remission, there was an elevation of serum IgG4 levels and renal dysfunction owing to bilateral hydronephrosis caused by a reemergence of the retroperitoneal mass. Evaluation by endoscopic retrograde cholangiopancreatography revealed a biliary stricture, suggesting sclerosing cholangitis which was observed without the presence of any pancreatic duct abnormality. The subsequent excellent results obtained using steroid therapy, namely the decrease in serum IgG4 levels and the regression of the retroperitoneal mass, strongly suggested that the present case was an IgG4-related sclerosing disease. Aside from high serum IgG4 concentrations, markedly elevated levels of serum IgE was found retrospectively, although the clinical significance remains unknown. When we encounter fibrotic diseases of unknown etiology, we should measure serum IgG4 concentrations and monitor the disease activity over long periods even after achieving clinical remission.

    Traditionally, the most commonly used source of bibliometric data is the Thomson ISI Web of Knowledge, in particular the (Social) Science Citation Index and the Journal Citation Reports, which provide the yearly Journal Impact Factors. This database used for the evaluation of researchers is not advantageous in the humanities, mainly because books, conference papers, and non-English journals, which are an important part of scientific activity, are not (well) covered. This paper presents the use of an alternative source of data, Google Scholar, and its benefits in calculating citation metrics in the humanities. Because of its broader range of data sources, the use of Google Scholar generally results in more comprehensive citation coverage in the humanities. This presentation compares and analyzes some international case studies with ISI Web of Knowledge and Google Scholar. The fields of economics, geography, social sciences, philosophy, and history are focused on to illustrate the differences of results between these two databases. To search for relevant publications in the Google Scholar database, the use of "Publish or Perish" and of CleanPoP, which the author developed to clean the results, are compared.

    Full Text Available The article discusses possible terminologies for labelling historical materials. Drawing on the history of the city of Cairo around the 12th century – to the Fatimid era and to later Ayyubid times – it looks at the documents of three religions on religious infrastructure donated by women. This reveals women’s ability to shape the public sphere. At least to a certain extent, the segregation of the sexes and the concept of the harem are questionable. This topic requires the reconstruction and re-reading of fragmental materials. Methodological reflections are helpful for dealing with different sources, mostly combinations of texts and archaeology, embedded in the current debate about material culture and media as well as materialization and mediation. It might seem anachronistic, but to specify these categories it is useful to compare this example with a contemporary study by Mia Lövheim on female Internet bloggers. In both cases we find women as self-confident agents in public spaces.

    Extranodal NK/T-cell lymphoma, nasal type (ENKTL-NT) is an aggressive extranodal non-Hodgkin lymphoma most commonly occurring in East Asia and Latin America but with increasing incidence in the U.S. Data on epidemiology, disease presentation, and outcome for European and North American (“Western”) cases are very limited. We review published landmark clinical studies on ENKTL-NT in the West and report in detail recent data, including our institutional experience. We highlight key observations in its epidemiology, natural history, and trends in clinical management. In the U.S., ENKTL-NT is more common among Asian Pacific Islanders (API) and Hispanics compared to non-Hispanic whites. Published studies indicate less heterogeneity in clinical presentation in Western ENKTL-NT compared to Asian patients. While there is variation in age at diagnosis, presence of antecedent lymphoproliferative disorders, and outcomes among racial/ethnic groups, the universal association of ENKTL-NT with EBV and the poor response of this neoplasm to anthracycline-based therapy are consistent across all geographic areas.

    The use of a statistical technique for paired comparisons using receiver operating characteristic (ROC) curves is illustrated by studying the extent to which clinical history altered the interpretation of computed tomographic (CT) examinations of the head. Eighty-nine CT examinations of the head were presented in random order to four readers, first with minimum history (age and sex) and then several weeks later with complete neutrological history as of the time the CT examination had been obtained. Using a paired ROC analysis, a small but significant (p < .05) improvement was detected for the interpretations in the presence of complete history; for readings without history the average area was 94.4% and for readings with history it was 97.7%

  13. Radiation safety actuality in Republic of Moldova

    2011-01-01

    Radioecological monitoring issues and radiation safety are actual in the Republic of Moldova. Japan events show us the possibility of natural disasters. Republic of Moldova is surrounded by 8 NPPs, the closest being at the distance of 160 km. Moldovas territory is in seismic zone where underground earthquake shocks reaches 7 points or more. Thatis why radiation safety and radioecological monitoring is actual in our republic. Traces of Chernobyl were left in Moldovas soils. The fallouts of radio nuclides formed on the soil surfaces in the Republic of Moldova following the Chernobyl Nuclear Power Station Accident have been continuously affected by attacks of both natural and technicaly generated agents since the time of fallout. During the past decade a shift in emphasis has taken place regarding the need for more complete and accurate information on reservoir sedimentation. Classical sedimentation surveys involve repeated field measurement and, therefore, this is probably the most costly and time consuming method. The application of radio nuclides, particularly Cs 137, for water erosion and sedimentation studies in Republic of Moldova has not been attempted so far. This paper presents the results obtained on reservoir sedimentation rates in an area subjected to wide range in land degradation dy sheet-rill erosion. The profil characteristics support the assumption that in most undisturbed sites there is a sharp decline in Cs 137 activity with increasing dept. Such an asymmetrical distribution of the Cs 137 would suggest a standard pattern in the form of a cantilever. If the validity of this assamption is accepted it is possible to define two major types of Cs 137 cantilever distribution: shallow and deep buried cantilever. The main criterion in classifying these pattents lies generally in the shape of Cs 137 depth profile and particularly in burial magnitude of Cs 137 peak derived from Chernobyl. Hills area has been impacted by greatest sendimentation. This regional

    This report presents the work that followed the CSSX model development completed in FY2002. The developed cesium and potassium extraction model was based on extraction data obtained from simple aqueous media. It was tested to ensure the validity of the prediction for the cesium extraction from actual waste. Compositions of the actual tank waste were obtained from the Savannah River Site personnel and were used to prepare defined simulants and to predict cesium distribution ratios using the model. It was therefore possible to compare the cesium distribution ratios obtained from the actual waste, the simulant, and the predicted values. It was determined that the predicted values agree with the measured values for the simulants. Predicted values also agreed, with three exceptions, with measured values for the tank wastes. Discrepancies were attributed in part to the uncertainty in the cation/anion balance in the actual waste composition, but likely more so to the uncertainty in the potassium concentration in the waste, given the demonstrated large competing effect of this metal on cesium extraction. It was demonstrated that the upper limit for the potassium concentration in the feed ought to not exceed 0.05 M in order to maintain suitable cesium distribution ratios

  15. Nanomaterials environmental risks and recycling: Actual issues

    2014-01-01

    Full Text Available Nanotechnologies are being spoken of as the driving force behind a new industrial revolution. Nanoscience has matured significantly during the last decade as it has transitioned from bench top science to applied technology. Presently, nanomaterials are used in a wide variety of commercial products such as electronic components, sports equipment, sun creams and biomedical applications. The size of nanoparticles allows them to interact strongly with biological structures, so they present potential human and environmental health risk. Nanometer size presents also a problem for separation, recovery, and reuse of the particulate matter. Therefore, industrial-scale manufacturing and use of nanomaterials could have strong impact on human health and the environment or the problematic of nanomaterials recycling. The catch-all term ''nanotechnology' is not sufficiently precise for risk governance and risk management purposes. The estimation of possible risks depends on a consideration of the life cycle of the material being produced, which involves understanding the processes and materials used in manufacture, the likely interactions between the product and individuals or the environment during its manufacture and useful life, and the methods used in its eventual disposal. From a risk-control point of view it will be necessary to systematically identify those critical issues, which should be looked at in more detail. Brief review of actual trends in nanomaterials environmental risks and recycling is given in this paper.

  17. Actual conditions of radiation control in radioisotope utilization field

    Kakihara, Koji

    1980-01-01

    It may be said that the actual conditions on radiation safety are being improved in utilizing radioisotopes or radiation in Japan. It depends greatly on the results of the voluntary effort of users and the regulations by the ''radiation injury prevention law'' and its relevant ordinances. However, the actual conditions of the strict observation of the law are much insufficient. According to the results of official inspection in 1978, 60% of whole enterprises concerned and 73% of educational and medical organizations were judged as incomplete. Such tendency should not be left as it is, but it should also be noticed that there are realities that critical accidents or injuries have not occurred even in such conditions as many violations mentioned above. Since the existing law has not been subjected to essential revision in the past two decades, it might be said that the law does not properly fit to the present conditions because the progress of related techniques was made during this period. Meanwhile, difficulties exist in measuring the low level concentration in the use of low energy radioisotopes or tracer experiments such as in the process analysis in factories or in the analysis of the movement of trace constituent in soil. Further, there is a problem on the necessity of securing the chief technicians handling radiation, and there is the contradiction that the chief technicians are useless in normal condition but are powerless in case of accidents. This situation should be improved as soon as possible. (Wakatsuki, Y.)

La importancia del primer tema es evidente porque vivimos en el mundo donde las grandes corporación transnacionales determinan los precios de sus productos en la medida mucho mayor que lo hacían los cárteles y los trusts del inicio del siglo XX. Y en lo que se refiere al segundo elemento, su actualidad esta dada por el hecho de que, al parecer, de nuevo vivimos en el período de grandes cambios del sistema económico del capitalismo que se manifiestan en: el creciente papel del capital ficticio en la reproducción del capital global; el paso en las políticas económicas de la lógica de Bretton Woods a la de neoconservadurismo y de Consenso de Washington; y, en las modificaciones de la forma y del mecanismo del ciclo económico.

  2. LAS ACTUALES REGLAS DE LA COMPETITIVIDAD INTERNACIONAL

    Full Text Available Este trabajo nace de una preocupación profunda por las acciones desplegadas por los países latinoamericanos en las pasadas dos décadas, asociadas a la integración al circuito global de intercambios. La confianza en que el comercio y la vinculación internacional procuraría el umbral máximo de bienestar a sus poblaciones, impulsó reformas estructurales que desmantelarían el carácter autárquico de sus aparatos productivos; proceso que caló profundamente en Argentina. Pero en este camino, en mayor o menor medida, las economías latinoamericanas no lograron un crecimiento económico sostenido, a pesar de haber recreado sus capacidades productivas y practicado su reestructuración política, salvo algunas economías regionales, o el dinamismo que exhibieron algunas ciudades y comunidades locales. El presente trabajo está dirigido a explorar los elementos que deben ser atendidos a partir de la caracterización del esquema global de producción e intercambio, el cual destaca la relevancia de la actuación de las políticas públicas y la gestión de las ciudades y regiones, espacios dinámicos de la economía global. La búsqueda de competitividad en las ciudades y regiones, como una exigencia de la actual agenda pública, deberá guiar los esfuerzos, por un lado, hacia el desarrollo de competencias en los ambientes locales, y por el otro, al fomento de las exportaciones para ganar competitividad internacional. Se hace presente la relevancia de atender a la construcción de la marca de sus productos, como herramientas para la proyección internacional, y el impulso de las ventas en los mercados externos.

  5. [History of viral hepatitis].

    Fonseca, José Carlos Ferraz da

    2010-01-01

    The history of viral hepatitis goes back thousands of years and is a fascinating one. When humans were first infected by such agents, a natural repetitive cycle began, with the capacity to infect billions of humans, thus decimating the population and causing sequelae in thousands of lives. This article reviews the available scientific information on the history of viral hepatitis. All the information was obtained through extensive bibliographic review, including original and review articles and consultations on the internet. There are reports on outbreaks of jaundice epidemics in China 5,000 years ago and in Babylon more than 2,500 years ago. The catastrophic history of great jaundice epidemics and pandemics is well known and generally associated with major wars. In the American Civil War, 40,000 cases occurred among Union troops. In 1885, an outbreak of catarrhal jaundice affected 191 workers at the Bremen shipyard (Germany) after vaccination against smallpox. In 1942, 28,585 soldiers became infected with hepatitis after inoculation with the yellow fever vaccine. The number of cases of hepatitis during the Second World War was estimated to be 16 million. Only in the twentieth century were the main agents causing viral hepatitis identified. The hepatitis B virus was the first to be discovered. In this paper, through reviewing the history of major epidemics caused by hepatitis viruses and the history of discovery of these agents, singular peculiarities were revealed. Examples of this include the accidental or chance discovery of the hepatitis B and D viruses.

    Extranodal NK/T cell lymphoma, nasal type (ENKTL-NT) is an aggressive extranodal non-Hodgkin lymphoma most commonly occurring in East Asia and Latin America but with increasing incidence in the United States. Data on epidemiology, disease presentation, and outcome for European and North American ("Western") cases are very limited. We review published landmark clinical studies on ENKTL-NT in the West and report in detail recent data, including our institutional experience. We highlight key observations in its epidemiology, natural history, and trends in clinical management. In the USA, ENKTL-NT is more common among Asian Pacific Islanders (API) and Hispanics compared to non-Hispanic whites. Published studies indicate less heterogeneity in clinical presentation in Western ENKTL-NT compared to Asian patients. While there is variation in age at diagnosis, presence of antecedent lymphoproliferative disorders, and outcomes among racial/ethnic groups, the universal association of ENKTL-NT with EBV and the poor response of this neoplasm to anthracycline-based therapy is consistent across all geographic areas. Data on epidemiology, disease presentation, and clinical outcomes in mature T cell and NK cell (T/NK cell) neoplasms, including ENKTL-NT, in Europe and North America are very limited. As the classification and diagnostic characterization of the currently recognized T/NK cell lymphoma disease entities continue to evolve, gaps and inconsistencies in data reporting across different studies are being recognized. Despite these limitations, several studies from the USA suggest that the incidence of ENKTL-NT is higher in Asian Pacific Islanders (API) and non-white Hispanics and that outcomes may be worse in non-whites. However, the universal association of ENKTL-NT with Epstein-Barr virus (EBV) across all ethnic groups suggests a common pathogenesis. Given the overlap between the entities included in the category of T/NK cell neoplasms, there is a need to further define

    In 283 women with infertility hysterosalpingographic (HSG) results have been analyzed. Fallopian tubes have been found to be patent in 196 subjects, whereas in 87 subjects distal or proximal unilateral or bilateral impatency has been observed. In 28 subjects with impatent fallopian tubes uterus malformations were found. 72 women with impatent oviducts were treated by laparoscopy alongside with oviduct chromotubation. On basis of clinical findings as well as cases reported in literature, HSG relevancy in infertility diagnostics has been proved. (author)

    Patients frequently experience long-term deficits in functional activity following anterior cruciate ligament reconstruction, and commonly present with decreased confidence and poor weight acceptance in the surgical knee. Adaptation of neuromuscular behaviors may be possible through plyometric training. Body weight support decreases intensity of landing sufficiently to allow increased training repetition. The purpose of this case report is to report the outcomes of a subject with a previous history of anterior cruciate ligament (ACL) reconstruction treated with high repetition jump training coupled with body weight support (BWS) as a primary intervention strategy. A 23-year old female, who had right ACL reconstruction seven years prior, presented with anterior knee pain and effusion following initiation of a running program. Following visual assessment of poor mechanics in single leg closed chain activities, landing mechanics were assessed using 3-D motion analysis of single leg landing off a 20 cm box. She then participated in an eight-week plyometric training program using a custom-designed body weight support system. The International Knee Documentation Committee Subjective Knee Form (IKDC) and the ACL-Return to Sport Index (ACL-RSI) were administered at the start and end of treatment as well as at follow-up testing. The subject's IKDC and ACL-RSI scores increased with training from 68% and 43% to 90% and 84%, respectively, and were retained at follow-up testing. Peak knee and hip flexion angles during landing increased from 47 ° and 53 ° to 72 ° and 80 ° respectively. Vertical ground reaction forces in landing decreased with training from 3.8 N/kg to 3.2 N/kg. All changes were retained two months following completion of training. The subject experienced meaningful changes in overall function. Retention of mechanical changes suggests that her new landing strategy had become a habitual pattern. Success with high volume plyometric training is

  18. Cimentaciones actuales de los rascacielos de Chicago

    López Ruiz, Álvaro

    1972-05-01

    Full Text Available The main characteristics of the land and the supporting rock are given, and the pattern of present performance of Chicago's deep foundations is briefly described. This city probably has some of the highest skyscrapers in the world with deep foundations resting on rock, and possibly as well, the highest building with foundations resting on soil. The construction of piles of large diameter, resting on rock and concreted dry, as prescribed by the City Code, is the weak point which sometimes makes it necessary to insert a permanent lining tube deep into the rock in order to obtain the required leaktightness, or to pump out significant quantities of water from the bottom of the excavations. The latter can cause the dragging away of earth from adjacent foundations resting on soil at a higher level, as with the drift of the phreatic level, with the consequent risk of producing appreciable subsidence, and even undermining. To overcome this problem we carried out for the first time in Chicago, a pre-sealing, by means of chemical injections, of the supporting rock of the periphery piles of some deep foundations, by drilling into the centre of each pile, which has also been useful as a means of examining the subsoil before proceeding to the perforation of each pile. This operation was carried out on the large diameter piles of the foundations of the Northern Trust Bank skyscraper, at present under construction, with very satisfactory results. The method of pre-sealing the rock used and the results obtained are described.Se presentan las características principales del terreno y de la roca de apoyo y se describe someramente la forma de ejecución actual de las cimentaciones profundas de Chicago.

  20. Quantity assessment of waste in the dismantlement of liquid waste treatment plant and its actual state

    From the progress of decommissioning project work of Tokyo City University Atomic Energy Research Institute, this paper reports the comparison between the actual amount of the waste generated during dismantlement work at liquid waste treatment facilities and the assessment quantity before starting the dismantlement. The quantity assessment was made on the basis of the installation license application, design specifications, drawings, records, history of use, site investigation results, etc. Since this quantity assessment did not take into account the dismantling contents of reservoir concrete, the assessed quantity of non-radioactive waste (NR waste) did not match the sum of actual NR waste. However, if an actually generated quantity of concrete of radioactive waste was added to the quantity assessment as NR waste, the quantity of actually generated NR waste and that of assessed NR waste were nearly consistent, which verified the validity of this assessment. This method is considered to be able to be utilized in the future quantity assessment of decommissioning work and the like. On the other hand, it was found that the number of drums that were actually stored tended to increase more than the estimated number of drum conversion. In old buildings, it is necessary to take into account the generation of waste other than radioactive materials in the quantity assessment stage and dismantlement stage. (A.O.)

    There was a time when almost all Western geography could be termed environmental history. In the late nineteenth century, physical geographers explained landscapes by describing how they had evolved. Likewise, human geographers saw society as shaped by the directing hands of the environment. By the 1960s this had very much changed. Process studies shortened the temporal framework in geographical explanation and cut the cord between nature and society. Now, physical and human...

  4. Models of hemapoietic changes on the basis of systematically collected case histories of radiation accident victims as well as pathophysiologically evaluated patients after chronic radiation exposure

    2004-01-01

    The research project ''Models of Hematopoietic Changes on the Basis of Systematically Collected Case Histories of Radiation Accident Victims as well as Pathophysiologically Evaluated Patients after Chronic Radiation Exposure'' required the investigation of four major research problem areas. First of all, biomathematical models were improved or newly developed allowing the simulation of the radiation induced response patterns of granulocytes, lymphocytes and blood platelets. The compartment model approach allowed the establishment of the correlation of such blood cell changes to the extent of damage at the level of hemopoietic stem cells distributed throughout the skeleton. The utilization of neural-network techniques resulted in a ''synergetic'' model that enables the medical doctor - using blood cell changes within the first 5-6 days after exposure - to predict the further course of illness and to allow a rational approach to clinical management. Secondly, available information on the clinical consequences of radiation exposure on more than 800 accident victims enabled the team to develop an entirely new concept to recognize and treat such persons. For this approach the biomathematical models were used to identify ''response categories'' (rather than dosimetrically defined ''exposure categories'') with an organ specific grading code of the severity of radiation-induced damage. This grading allowed the semi-quantitative damage assessment of the hemopoiesis, the neurovascular system, the gastrointestinal as well as the cutaneous system. It forms the basis for a ''weighted'' prognosis and for the logistics of radiation accident medical management. In the third project domain, models were developed to understand pathophysiological mechanisms of biological consequences of chronic radiation in human beings (former USSR) as well as in a preclinical dog study (USA). From a large group of patients with the diagnosis of ''Chronic Radiation Sickness'' more than 80 were

    2011-09-01

    For some years now, the history of modern mathematics and the history of modern science have developed independently. A step toward a reunification that would benefit both disciplines could come about through a revived appreciation of mathematical practice. Detailed studies of what mathematicians actually do, whether local or broadly based, have often led in recent work to examinations of the social, cultural, and national contexts, and more can be done. Another recent approach toward a historical understanding of the abstractness of modern mathematics has been to see it as a species of modernism, and this thesis will be tested by the raft of works on the history of modern applied mathematics currently under way.

    Full Text Available Abstract One of the most fundamental acts of historiography is to classify historical information in diachronic axis. The method of this classification or periodization shows the theoretical approach of the historian and determines the structure and the form of his history.

    retrospective study examined the OR turnaround data of 875 elective surgery cases scheduled at the Marienhospital, Vechta, Germany, between July and October 2014. The frequency distributions of planned and actual OR turnaround times were compared and correlations between turnaround times and various factors were established, including the time of day of the procedure, patient age and the planned duration of the surgery. Results: There was a significant difference between mean planned and actual OR turnaround times (0.32 versus 0.64 hours; P <0.001. In addition, significant correlations were noted between actual OR turnaround times and the time of day of the surgery, patient age, actual duration of the procedure and staffing changes affecting the surgeon or the medical specialty of the surgery (P <0.001 each. The quotient of actual/planned OR turnaround times ranged from 1.733–3.000. Conclusion: Significant discrepancies between planned and actual OR turnaround times were noted during the study period. Such findings may be potentially used in future studies to establish a tool to improve OR planning, measure OR management performance and enable benchmarking.

    Heo Joon is one of the best-known physicians of the Chosun Dynasty, the last imperial dynasty (1392~1910) of Korea. He had served King Seonjo () during his practice, and has produced many publications on medicine. Then, how did he actually treat the patients? So far, other than the case when he treated Gwanghaegun's smallpox, it is not clearly known how and when he attended and treated the ill. In his most famous book, the Treasured Mirror of Eastern Medicine, he details the physiopathological mechanisms, diagnoses, treatments or prescriptions, and treatment cases, however, it is not clear if they're from his own clinical experiences. Nevertheless, based on the written method, the original information is reconstituted according to its respective editors of the TMEM, a particular case being included may be considered as an agreement and acceptance of an actual treatment executed. This research analyzes what type of medicinal theory that the main writer Heo Joon employed in his real treatments, as well as how he diagnosed and treated diseases. After analyzing the complete series of the TMEM, we found a total of 301 clinical cases. Here, one may wonder, why does the Section of Inner and External Bodily Elements, that deal with diseases and the structure of the body, have far outnumber cases than the Section of Miscellaneous Disorders? Why does the TMEM introduce the various types of disease experiences and treatment cases, medical cases, simple treatments, nurturing life, materia medica, and also include supernatural phenomena? Why does the TMEM include the experiences and cases from the book published in the Song, Jin, Yuan dynasty of China, moreover in the Ming Dynasty of its time. These questions can be answered to the extent that Heo Joon and the others who participated in completing the book sought to justify the new clinical medicine practices, and because it had to be acceptable to the Confucius beliefs which dominated the society, and also because the book

    The Cygnus Dual Beam Radiographic Facility consists of two identical radiographic sources: Cygnus 1 and Cygnus 2. This Radiographic Facility is located in an underground tunnel test area at the Nevada Test Site. The sources were developed to produce high-resolution images for dynamic plutonium experiments. This work will recount and discuss salient maintenance and operational issues encountered during the history of Cygnus. A brief description of Cygnus systems and rational for design selections will set the stage for this historical narrative. It is intended to highlight the team-derived solutions for technical problems encountered during extended periods of maintenance and operation. While many of the issues are typical to pulsed power systems, some of the solutions are unique. It is hoped that other source teams will benefit from this presentation, as well as other necessary disciplines (e.g., source users, system architects, facility designers and managers, funding managers, and team leaders)

  2. Environmental history

    2017-01-01

    Environmental history is an interdisciplinary pursuit that has developed as a form of conscience to counter an increasingly powerful, forward-looking liberal theory of the environment. It deals with the relations between environmental ideas and materialities, from the work of the geographers George...... Perkins Marsh, Carl Sauer, and Clarence Glacken, to more recent global-scale assessments of the impact of the “great acceleration” since 1950. Today’s “runaway world” paradoxically embraces risk management in an attempt to determine its own future whilst generating a whole new category of “manufactured...... risks”. These are exposed by environmental history’s focus on long-run analysis and its narrative form that identifies the stories that we tell ourselves about nature. How a better understanding of past environmental transformations helps to analyse society and agency, and what this can mean...

    ENGLISH ABSTRACT: To develop high quality products, a designer has to consider various influential factors, one of which is ergonomics. And to fashion a specific product for the user, a designer needs expert knowledge of the user’s requirements. However, expert knowledge can also be accessed through an intelligent advisory system for ergonomic design support. The effectiveness of such an expert system depends mainly on the quality of the knowledge base and on the appropriateness of the system's inference engine. Data for the system’s knowledge base can be collected in different ways. One approach is to study relevant projects to collect appropriate ergonomic solutions; another is to recognise bottlenecks in ergonomic design. This paper presents a case study of the design of an actual chainsaw – with emphasis on ergonomic design solutions – that can be transformed into ergonomic design recommendations. At the end of the paper, an application of one of the derived recommendations within the knowledge base of the intelligent advisory system is presented.

    In the framework of the ESA-funded project "GOCE High-level Processing Facility", an operational hardware and software system for the scientific processing (Level 1B to Level 2) of GOCE data has been set up by the European GOCE Gravity Consortium EGG-C. One key component of this software system is the processing of a spherical harmonic Earth's gravity field model and the corresponding full variance-covariance matrix from the precise GOCE orbit and calibrated and corrected satellite gravity gradiometry (SGG) data. In the framework of the time-wise approach a combination of several processing strategies for the optimum exploitation of the information content of the GOCE data has been set up: The Quick-Look Gravity Field Analysis is applied to derive a fast diagnosis of the GOCE system performance and to monitor the quality of the input data. In the Core Solver processing a rigorous high-precision solution of the very large normal equation systems is derived by applying parallel processing techniques on a PC cluster. Before the availability of real GOCE data, by means of a realistic numerical case study, which is based on the actual GOCE orbit and mission scenario and simulation data stemming from the most recent ESA end-to-end simulation, the expected GOCE gravity field performance is evaluated. Results from this simulation as well as recently developed features of the software system are presented. Additionally some aspects on data combination with complementary data sources are addressed.

    Increasing incidence of squamous cell carcinoma (SCC) of the oral cavity and oropharynx is reported in young adults. However, there is a paucity regarding etiology and risk factors. To evaluate the exposure potential carcinogenic factors among a sample aged 45 years and younger, diagnosed with SCC of the oral cavity and oropharynx. Eighty-five case samples aged 18-45 years, diagnosed with SCC of the oral cavity and oropharynx were compared with 85 controls who had never had cancer, matched for age and sex. This study was conducted by questionnaire-based interviews. Questionnaire contained items about exposure to the following risk factors: Caries prevalence, oral hygiene status, dental trauma, dental visit, stress, family history of cancer, environmental exposure to potential carcinogens, diet, body mass index (BMI), habits such as smoking, tobacco chewing, betel quid/pan, or supari. Odds ratios (ORs) of oral and pharyngeal cancer and the corresponding 95% confidence intervals were estimated using multiple logistic regression models. Poral hygiene, stress, dental trauma, low BMI, family history of cancer, exposure to environmental carcinogens, and habit of placement of quid for 11-20 years. An increased risk of oral and pharyngeal cancer was seen in cases who had poor oral hygiene, stress, dental trauma, low BMI, family history of cancer, exposure to environmental carcinogens, and habit of placement of quid.

    Purpose The purpose of this study was to examine associations between perceived risk and actual risk of type 2 diabetes by race and/or ethnicity. Methods The study sample included 10 999 adults from the 2011 to 2014 National Health and Nutrition Examination Survey. Sociodemographic, clinical, and behavioral data were collected using interviews and physical examinations. Participants were asked if they felt at risk for diabetes or prediabetes and then asked the reasons why. Data analyses were conducted with SAS to properly analyze complex survey data. Results About 86% of the sample (n = 9496) answered the risk perception question for diabetes, and among those, 28.4% indicated having a high perceived risk. Among this subsample, 38.3% were identified as having an actual risk for prediabetes or diabetes according to the American Diabetes Association guidelines. Across all race groups, the most frequently reported risk factors participants believed to contribute to their risk for diabetes were family history of diabetes, obesity, and poor diet habits. When the percentage of participants with an actual risk factor who correctly perceived it as a risk factor was examined, fewer Asians correctly perceived weight status and physical activity level as a risk for diabetes in contrast to the other racial/ethnic groups. Conclusions Our study showed that when perception was compared to actual risks, associations differed statistically by race. It will be essential to discuss their risk perception to proper screening for diabetes and relevant lifestyle modifications to prevent and delay the onset of diabetes.

  9. Case study for a fit-to-purpose regulatory framework: the history and reasons for the evolution-in the French regulation regarding decommissioning

    Full text: This paper exposes the regulatory approach for the safety of decommissioning in France, from an historical perspective. The first regulatory framework concerning decommissioning was introduced in the end of the 1980's and considered decommissioning as successive important modifications of the facility, which lead to multiple successive licenses. The first feedback from actual decommissioning projects lead the nuclear safety authority to reconsider the regulatory approach of decommissioning. The new approach privileges an integrated approach to the decommissioning projects, with an initial decommissioning license authorizing the complete project, and puts more weight on the responsibility of the licensee, fostering the organization of internal safety commissions which are allowed to authorize minor operations that do not put into question the global facility safety demonstration. This new regulatory approach was implemented in 2003 and new corresponding licensing procedures are already under way. It is thought that the new regulatory framework for decommissioning that has been introduced in 2003 will allow to regulate in a far more efficient way the decommissioning projects to come, while guarantying a high safety level, adapting the regulatory burden to the actual hazards, and allowing the licensee for the needed flexibility. Taking advantage of this new framework, licensees have already filed many decommissioning license applications, and decommissioning project licensing is currently one of the main tasks of the nuclear safety authority in France. Many such licenses, for all types of nuclear facilities, will be granted in the next few years. (authors)

    The sediment history of this productive, hardwater lake (Wintergreen Lake in southern Michigan) developed as five periods of increasing eutrophy, each strongly influenced by a hybrid basin morphometry. This morphometry led to higher productivity per unit area by macrophytic plants in littoral waters of the lake than by phytoplankton in pelagic waters. Climate and trophic conditions during each of the five periods between 14,000 and 0 B.P. are postulated.

    To determine the outcome of and prognostic indicators for dogs and cats with pneumoperitoneum and no history of penetrating trauma. Retrospective study. 43 dogs and 11 cats. Medical records of dogs and cats with radiographic evidence of pneumoperitoneum and no history of penetrating trauma were reviewed. Information collected included signalment, previous medical problems, initial complaint, duration of illness, physical examination findings, radiographic findings, laboratory abnormalities, abdominocentesis results, bacterial culture results, concurrent diseases, hospitalization time, and outcome. Abdominal radiographs were reviewed, and radiographic severity of pneumoperitoneum was classified. For those animals that underwent exploratory laparotomy, time from admission to surgery and results of histologic examination of biopsy specimens were recorded. 24 (44%) animals survived and were discharged from the hospital, but none of the variables examined was associated with whether animals survived. Rupture of the gastrointestinal tract was the cause of pneumoperitoneum in 40 animals. However, cause and location of gastrointestinal tract rupture was not associated with whether animals survived. Twenty-three of 40 (58%) animals that underwent exploratory laparotomy survived, compared with only 1 of 14 animals that did not undergo surgery. Results suggest that pneumoperitoneum in dogs and cats without any history of penetrating trauma is most commonly associated with rupture of the gastrointestinal tract and requires immediate surgical intervention. Even when appropriate treatment is instituted, the shortterm prognosis is only fair.

    2004-06-01

    Full Text Available The White stork Ciconia ciconia has been the object of several successful reintroduction programmes in the last decades. As a consequence, populations have been monitored over large spatial scales. Despite these intense efforts, very few reliable estimates of life history traits are available for this species. Such general knowledge however constitutes a prerequisite for investigating the consequences of conservation measures. Using the large–scale and long–term ringing and resighting data set of White storks in the Netherlands, we investigated the variation of survival and resighting rates with age, time and previous individual resighting history, and in a second step supplementary feeding, using capture–recapture models. Providing food did not seem to affect survival directly, but may have an indirect effect via the alteration of migratory behaviour. Large–scale population monitoring is important in obtaining precise and reliable estimates of life history traits and assessing the consequences of conservation measures on these traits, which will prove useful for managers to take adequate measures in future conservation strategies.

    Homeopathy began to spread soon after it was formulated by Samuel Hahnemann in the early 1800s, reaching the Southern Cone in the 1830s. In processes of this kind, one figure is often cited as being responsible for introducing it, often attaining quasi-mythical status. Little is known, however, about how homeopathy reached Argentina at that time. Through archival research, we discovered that medical and lay homeopaths circulated between Rio de Janeiro and Buenos Aires. Given the well-known proselytizing of the circles gravitating around lay homeopaths B. Mure and J.V. Martins in Rio de Janeiro, the documents indicate that this movement actually went as far as Argentina, which had not been confirmed until now.

    There is a large amount of information regarding risk factors for fifth metatarsal stress fractures; however, there are few studies involving large numbers of subjects. This study aimed to compare the static foot alignment and distribution of foot pressure of athletes with and without a history of fifth metatarsal stress fractures. The study participants comprised 335 collegiate male soccer players. Twenty-nine with a history of fifth metatarsal stress fractures were in the fracture group and 306 were in the control group (with subgroups as follows: 30 in the fracture foot group and 28 in the non-fracture group). We measured the foot length, arch height, weight-bearing leg-heel alignment, non-weight-bearing leg-heel alignment, forefoot angle relative to the rearfoot, forefoot angle relative to the horizontal axis, and foot pressure. The non-weight-bearing leg-heel alignment was significantly smaller and the forefoot angle relative to the rearfoot was significantly greater in the fracture foot group than in the control foot group (P = 0.049 and P = 0.038, respectively). With regard to plantar pressure, there were no significant differences among the groups. Midfield players had significantly higher rates of fifth metatarsal stress fracture in their histories, whereas defenders had significantly lower rates (chi-square = 13.2, P stress fractures according to the type of foot (kicking foot vs. pivoting foot) or the severity of ankle sprain. Playing the midfield position and having an everted rearfoot and inverted forefoot alignment were associated with fifth metatarsal stress fractures. This information may be helpful for preventing fifth metatarsal stress fracture recurrence. More detailed load evaluations and a prospective study are needed in the future.

  1. History at the intersection of disability and public health: the case of John Galsworthy and disabled soldiers of the First World War.

    2011-01-01

    The author presented an earlier version of this historical article to the Disability Section of the American Public Health Association (November 2009). It is part of his ongoing research in the social and cultural history of medicine as the field intersects with the history of disability, veterans, and public health, as well as current issues that touch all of these areas. This article introduces readers to perspectives on disability held by the British novelist John Galsworthy (1867-1933), which he developed primarily through his philanthropic support for and his compositions about rehabilitation programs for British and American soldiers disabled in the First World War (1914-1918). Readers will learn that Galsworthy's perspectives are as much about his identity as an individual with disabilities as they are about men disabled in the "war to end all wars." The rediscovery of Galsworthy's experiences and words more than 90 years after the end of World War I reveals how history is present today at the intersection of disability and public health. Indeed, the story of Galsworthy ultimately seeking to forget his own experiences during the "Great War," as well as the very physical and psychological disability caused by that conflict, can inspire public health professionals and disability rights advocates today to remember-indeed, to advocate for-men and women who served in battle and have returned home to realize renewed health and social participation despite permanent physical and psychological wounds. Readers will note that language used throughout this article to describe disability is period-specific and therefore not keeping with current conventions. Published by Elsevier Inc.

    Marginal populations are often geographically isolated, smaller, and more fragmented than central populations and may frequently have to face suboptimal local environmental conditions. Persistence of these populations frequently involves the development of adaptive traits at phenotypic and genetic levels. We compared population structure and demographic variables in two fucoid macroalgal species contrasting in patterns of genetic diversity and phenotypic plasticity at their southern distribution limit with a more central location. Models were Ascophyllum nodosum (L.) Le Jol. (whose extreme longevity and generation overlap may buffer genetic loss by drift) and Fucus serratus L. (with low genetic diversity at southern margins). At edge locations, both species exhibited trends in life-history traits compatible with population persistence but by using different mechanisms. Marginal populations of A. nodosum had higher reproductive output in spite of similar mortality rates at all life stages, making edge populations denser and with smaller individuals. In F. serratus, rather than demographic changes, marginal populations differed in habitat, occurring restricted to a narrower vertical habitat range. We conclude that persistence of both A. nodosum and F. serratus at the southern-edge locations depends on different strategies. Marginal population persistence in A. nodosum relies on a differentiation in life-history traits, whereas F. serratus, putatively poorer in evolvability potential, is restricted to a narrower vertical range at border locations. These results contribute to the general understanding of mechanisms that lead to population persistence at distributional limits and to predict population resilience under a scenario of environmental change. © 2011 Phycological Society of America.

  4. Solitary intracranial tuberculoma mimicking a malignant tumor in a patient without tubercular lesions or a history of disease: a case report

    Full Text Available Cerebral tuberculoma is a rare cause of intracranial mass. In Latin America and Colombia where tuberculosis is endemic, it represents between 5 and 30% of brain tumours. A 53-year-old Colombian woman was admitted to a third-level hospital in Cali, Colombia, after reporting loss of consciousness, headache, paresthesia, and flight of ideas for a two-week period. Imaging studies showed a left frontal mass of malignant appearance whose first possible diagnosis was metastatic neoplasia or glioma. With the initial results, absence of history of chronic infectious diseases and a history of thyroidectomy, a surgical procedure was carried out and a histopathological and molecular evaluation was conducted. The pathology report noted necrotizing granulomatous inflammation and tissue staining and molecular tests for detection of M. tuberculosis were positive and the patient was managed with anti-tubercular treatment. Intracranial masses are frequently targeted as a malignant neoplastic disease for surgical treatment. Considering an infectious etiology must be a diagnostic option.

    Little is known about the epidemiology of suicide attempts among psychiatric outpatients in Mexico. This study was aimed to determine the socio-demographic, clinical and behavioral characteristics associated with suicide attempts in psychiatric outpatients in two public hospitals in Durango, Mexico. Two hundred seventy six psychiatric outpatients (154 suicide attempters and 122 patients without suicide attempt history) attended the two public hospitals in Durango City, Mexico were included in this study. Socio-demographic, clinical and behavioral characteristics were obtained retrospectively from all outpatients and compared in relation to the presence or absence of suicide attempt history. Increased prevalence of suicide attempts was associated with mental and behavioral disorders due to psychoactive substance use (F10-19) (P=0.01), schizophrenia, schizotypal and delusional disorders (F20-29) (P=0.02), mood (affective) disorders (F30-39) (Purban residence (OR=2.31, 95% CI: 1.17-4.57; P=0.01), memory impairment (OR=1.91, 95% CI: 1.07-3.40; P=0.02), alcohol consumption (OR=2.39, 95% CI: 1.21-4.70; P=0.01), and sexual promiscuity (OR=3.90, 95% CI: 1.74-8.77; PMexico. Results may be useful for an optimal planning of preventive measures against suicide attempts in psychiatric outpatients.

    Full Text Available This study is meant to examine the relationships of several antecedents of actual purchase of herbal product in Malaysia. Actual purchase is considered to have a vital link to a business success. The study identified eight antecedents of consumer actual purchase such as intention, attitude, social influence, product safety and culture belief. A total of 473 respondents (about 82% completed and returned the questionnaire. A seven point Likert scale was used to measure responses. The data were analyzed using Partial Least Squares (PLS path modeling. The path coefficient results supported the direct influence of intention, attitude, social influence and product safety on actual buying. Moreover, the findings reveal that attitude, social influence, product safety, and culture belief also influenced buying intention.

    The electrodermal response (EDR) of children watching a violent show was measured. Particular attention was paid to the type of violence (actual or implied) that prompted an EDR. In addition, the impact of the auditory component (sounds associated with violence) of the show was evaluated. Implied violent stimuli, such as the villain's face, elicited the strongest EDR. The elements that elicited the weakest responses were the actual violent stimuli, such as stabbing. The background noise and voices of the sound track enhanced the total number of EDRs. The results suggest that implied violence may elicit more fear (as measured by EDRs) than actual violence does and that sounds alone contribute significantly to the emotional response to television violence. One should not, therefore, categorically assume that a show with mostly actual violence evokes less fear than one with mostly implied violence.

    Seismic input in the form of floor response spectra (FRS) are needed in seismic design and evaluation of equipment in nuclear power plants (NPPs). These are typically determined by analytical procedures using mathematical models of NPP structures and are known to be very conservative. Recorded earthquake data, in the form of acceleration response spectra computed from the recorded acceleration time histories, have been collected from NPP structures located in seismically active areas. Statistics of the ratios, or amplification factors, between the FRS at typical floors and the acceleration response spectra at the basemat or in the freefield, are obtained for typical NPP structures. These amplification factors are typically in terms of the peak spectral and zero period values, as well as a function of frequency. The average + 1σ values of these ratios, for those cases where enough data are available, are proposed to be used as limits to analytically calculated FRS, or for construction of simplified FRS for determining seismic input or demand in equipment qualification.

  9. The role of history in science.

    Creath, Richard

    2010-01-01

    The case often made by scientists (and philosophers) against history and the history of science in particular is clear. Insofar as a field of study is historical as opposed to law-based, it is trivial. Insofar as a field attends to the past of science as opposed to current scientific issues, its efforts are derivative and, by diverting attention from acquiring new knowledge, deplorable. This case would be devastating if true, but it has almost everything almost exactly wrong. The study of history and the study of laws are not mutually exclusive, but unavoidably linked. Neither can be pursued without the other. Much the same can be said of the history of science. The history of science is neither a distraction from "real" science nor even merely a help to science. Rather, the history of science is an essential part of each science. Seeing that this is so requires a broader understanding of both history and science.

    Primary angiosarcoma of the bone (PAB) is a rare and fatal high-grade malignant vascular bone tumor. We report a rare case of multicentric PAB mimicking bone metastasis in a 59-year-old female patient with a history of sigmoid colon cancer. This patient complained of lower back and pelvic pain and presented with multiple osteolytic bone lesions on plain radiography and pelvic computed tomography. First, bone metastasis of sigmoid colon cancer was suspected. However, on the {sup 18}F-fluorodeoxyglucose ({sup 18}F-FDG) positron emission tomography/computed tomography (PET/CT) scan, the patient presented unusual multiple hypermetabolic osteolytic bone lesions involving contiguous bones of the lower half of the body. After bone biopsy, these lesions were confirmed to be multicentric PAB. To the best of our knowledge, this is the first case report of an {sup 18}F-FDG PET/CT scan in a patient with multicentric primary bone angiosarcoma.

    Spectrum-compatible earthquake time histories have been widely used for seismic analysis and design. In this paper, a data processing method, Hilbert-Huang transform, is applied to generate earthquake time histories compatible with the target seismic design spectra based on multiple actual earthquake records. Each actual earthquake record is decomposed into several components of time-dependent amplitude and frequency by Hilbert-Huang transform. The spectrum-compatible earthquake time history ...

  16. Actual heating energy savings in thermally renovated Dutch dwellings

    The register of the Dutch social housing stock was analysed, containing 300.000 dwellings, renovated between 2010 and 2013. The main objective was twofold: to evaluate the performance gap in these dwellings before and after the renovation and to establish what renovation measures achieve the highest reduction of consumption, particularly in practice (actual savings). The results showed large performance gaps in dwellings with low R and high U values, local heating systems, changes from a non-condensing into a condensing boiler and upgrades to a natural ventilation system. Regarding the actual effectiveness of renovation measures, replacement of old gas boilers with more efficient ones yields the highest energy reduction, followed by deep improvements of windows. Installing mechanical ventilation yields a small reduction compared to other measures, but still much larger than theoretically expected. The paper shows once more that the calculation method currently in use cannot be considered accurate if compared to actual consumption. The study demonstrated that unrealistic theoretical efficiencies of heating systems and insulation values are causing a part of the performance gap. Nowadays, large datasets of buildings thermal performance and actual consumption offer an opportunity to improve these misconceptions. - Highlights: • Performance gap is lower in more efficient buildings. • Replacements of gas boilers – the most energy reduction among renovation measures. • Replacing the ventilation system yields a much larger reduction than expected. • How well are the standard values of the calculation methods defined? • Provide large public building performance databases including actual use data.

    The rapid increase in shale gas production in the USA has triggered a growing interest in unconventional resources in Eastern and Northern Europe. In this framework, the potential shale gas reserves in Poland are the most promising in Europe, extending from the Baltic Sea to the Ukraine border. In this area, the Baltic, Podlasie and Lublin basins have already become objective of shale gas exploration and the Holy Cross Mountains (HCM, Central Poland) represents the outcropping analog of the buried targeted Lower Paleozoic successions, providing a unique opportunity to study and assess source rock potential. In this work, we provide new thermal maturity data of Paleozoic rocks exposed in the HCM. A multi-method approach, coupling organic matter/graptolites (i.e., marine organoclasts) optical analysis and X-ray diffraction of clay-sized fraction of sediments, was applied to constrain the burial - thermal evolution of the sedimentary succession. The investigated area of the HCM includes two different tectonic blocks: the Łysogóry region to the North and the Kielce region to the South, separated by the Holy Cross Fault (HCF). lllite content in mixed layer illite-smectite determinations and vitrinite/graptolites reflectance measurements (Roeq%), performed on samples (Cambrian - Devonian) collected from both the regions, show a substantial difference between the two blocks in terms of thermal maturity and burial history. Roeq% values in the southern block range from 0.5% to 1.0%, with few exceptions, indicating early to mid-mature stage of hydrocarbon generation. Samples collected in the northern block show much higher values, mainly from 1.2% up to 1.7%, representative of the gas generation window. The I-S ordering type also shows relevant differences in the two blocks. In the southern block, mixed-layered clay minerals varies from R1 (short-range) to R3 (long-range), whereas R3 structures are recorded in the northern block. Vitrinite reflectance and mixed-layer I

    Different remote sensing methods for detecting variations in agricultural fields have been studied in last two decades. There are already existing systems for planning and applying e.g. nitrogen fertilizers to the cereal crop fields. However, there are disadvantages such as high costs, adaptability, reliability, resolution aspects and final products dissemination. With an unmanned aerial vehicle (UAV) based airborne methods, data collection can be performed cost-efficiently with desired spatial and temporal resolutions, below clouds and under diverse weather conditions. A new Fabry-Perot interferometer based hyperspectral imaging technology implemented in an UAV has been introduced. In this research, we studied the possibilities of exploiting classified raster maps from hyperspectral data to produce a work task for a precision fertilizer application. The UAV flight campaign was performed in a wheat test field in Finland in the summer of 2012. Based on the campaign, we have classified raster maps estimating the biomass and nitrogen contents at approximately stage 34 in the Zadoks scale. We combined the classified maps with farm history data such as previous yield maps. Then we generalized the combined results and transformed it to a vectorized zonal task map suitable for farm machinery. We present the selected weights for each dataset in the processing chain and the resultant variable rate application (VRA) task. The additional fertilization according to the generated task was shown to be beneficial for the amount of yield. However, our study is indicating that there are still many uncertainties within the process chain.

    As part of its expanding Astrophysics program, Fermilab is participating in the Digital Sky Survey (DSS). Fermilab is part of a collaboration involving University of Chicago, Princeton University, and the Institute of Advanced Studies (at Princeton). The DSS main results will be a photometric imaging survey and a redshift survey of galaxies and color-selected quasars over pi steradians of the Northern Galactic Cap. This paper focuses on our use of Computer Aided Software Engineering (CASE) in specifying the data system for DSS. Extensions to standard methodologies were necessary to compensate for tool shortcomings and to improve communication amongst the collaboration members. One such important extension was the incorporation of CASE information into the specification document.

  20. Exaggerating Accessible Differences: When Gender Stereotypes Overestimate Actual Group Differences.

    2017-09-01

    Stereotypes are often presumed to exaggerate group differences, but empirical evidence is mixed. We suggest exaggeration is moderated by the accessibility of specific stereotype content. In particular, because the most accessible stereotype contents are attributes perceived to differ between groups, those attributes are most likely to exaggerate actual group differences due to regression to the mean. We tested this hypothesis using a highly accessible gender stereotype: that women are more socially sensitive than men. We confirmed that the most accessible stereotype content involves attributes perceived to differ between groups (pretest), and that these stereotypes contain some accuracy but significantly exaggerate actual gender differences (Experiment 1). We observe less exaggeration when judging less accessible stereotype content (Experiment 2), or when judging individual men and women (Experiment 3). Considering the accessibility of specific stereotype content may explain when stereotypes exaggerate actual group differences and when they do not.
