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

Case Histories of Landslide Impact: A Database-driven Approach

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

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

Lee, C.F.

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

Perceived and actual social discrimination: the case of overweight and social inclusion.

Hartung, Freda-Marie; Renner, Britta

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 Body Mass Index (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.

It is well known that carcinomas of the gastrointestinal tract are frequently associated with peritoneal carcinomatosis. In contrast to that entity extensive involvement of the peritoneal cavity with malignant lymphoma is rare. This is the first case reporting coexistence of peritoneal lymphomatosis and a previous history of colon cancer, which is a highly challenging clinical situation. If not aware of this unusual condition medical history, radiologic finding and laboratory data alone can lead to wrong diagnosis as in this case

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.

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.

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

History of mathematics and history of science reunited?

Science.gov (United States)

Gray, Jeremy

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.

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

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 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

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.

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

2017-06-15

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.

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.

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

Science.gov (United States)

Keuck, Lara

2017-11-27

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.

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

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)

To develop a tool for assessing audiology students taking a case history and giving feedback with simulated patients (SP). Single observation, single group design. 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.

Geothermal systems: Principles and case histories

Science.gov (United States)

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.

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.

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.

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

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

The expected and actual communication of health care workers during the management of intrapartum: An interpretive multiple case study

Directory of Open Access Journals (Sweden)

Doreen K.M. M'Rithaa

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.

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.

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.

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

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.

Vibro Replacement, Dynamic Compaction, and Vibro Compaction case histories for petroleum storage tank facilities

Energy Technology Data Exchange (ETDEWEB)

Beaton, N; Scott, J. [Geopac West Ltd., Richmond, BC (Canada)

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.

Complex regional pain syndromes (CRPS type 1 validating case histories

Directory of Open Access Journals (Sweden)

P. Berger

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.

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

Science.gov (United States)

Drummond, Rachel; Gall, John A M

2017-02-01

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.

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.

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.

Towards Designing Android Faces after Actual Humans

Using their face as their prior affective interface, android robots and other agents embody emotional facial expressions, and convey messages on their identity, gender, age, race, and attractiveness. We are examining whether androids can convey emotionally relevant information via their static...... facial sig-nals, just as humans do. Based on the fact that social information can be accu-rately identified from still images of nonexpressive unknown faces, a judgment paradigm was employed to discover, and compare the style of facial expres-sions of the Geminoid-DK android (modeled after an actual...... initially made for the Original, suggesting that androids inherit the same style of facial expression as their originals. Our findings support the case of designing android faces after specific actual persons who portray facial features that are familiar to the users, and also relevant to the notion...

The effects of perceived and actual financial knowledge on regular personal savings: Case of Vietnam

Directory of Open Access Journals (Sweden)

Thi Anh Nhu Nguyen

2017-06-01

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.

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.

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.

1. Detection of sodium leakages in sodium circuits. 2. Actions in case of potentially dangerous situations. 3. Actual case histories

International Nuclear Information System (INIS)

Jansing, W.Th.

1971-01-01

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

2000-07-01

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.

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.

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.

Burke, G.K.; Crockford, R.M.; Achhorner, F.N.

1997-01-01

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

Life history dependent morphometric variation in stream-dwelling Atlantic salmon

Letcher, B.H.

2003-01-01

The time course of morphometric variation among life histories for stream-dwelling Atlantic salmon (Salmo salar L.) parr (age-0+ to age-2+) was analyzed. Possible life histories were combinations of parr maturity status in the autumn (mature or immature) and age at outmigration (smolt at age-2+ or later age). Actual life histories expressed with enough fish for analysis in the 1997 cohort were immature/age-2+ smolt, mature/age-2 +smolt, and mature/age-2+ non-smolt. Tagged fish were assigned to one of the three life histories and digital pictures from the field were analyzed using landmark-based geometric morphometrics. Results indicated that successful grouping of fish according to life history varied with fish age, but that fish could be grouped before the actual expression of the life histories. By March (age-1+), fish were successfully grouped using a descriptive discriminant function and successful assignment ranged from 84 to 97% for the remainder of stream residence. A jackknife of the discriminant function revealed an average life history prediction success of 67% from age-1+ summer to smolting. Low sample numbers for one of the life histories may have limited prediction success. A MANOVA on the shape descriptors (relative warps) also indicated significant differences in shape among life histories from age-1+ summer through to smolting. Across all samples, shape varied significantly with size. Within samples, shape did not vary significantly with size for samples from December (age-0+) to May (age-1+). During the age-1+ summer however, shape varied significantly with size, but the relationship between shape and size was not different among life histories. In the autumn (age-1+) and winter (age-2+), life history differences explained a significant portion of the change in shape with size. Life history dependent morphometric variation may be useful to indicate the timing of early expressions of life history variation and as a tool to explore temporal and

Diagnosis of penicillin allergy revisited: the value of case history, skin testing, specific IgE and prolonged challenge.

2013-08-01

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.

The history of nuclear fear

International Nuclear Information System (INIS)

Weart, S.

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

Synthetic seismic acceleration time-histories and their acceptance criteria

International Nuclear Information System (INIS)

Xu Hong

1996-01-01

In seismic dynamic response analysis of structures and equipment, time-history analysis is now widely used. The 3-D seismic acceleration time-histories or 3-D seismic displacement time-histories are required in the 3-D seismic dynamic response analysis as the seismic excitation input data. Because of the lack of actual acceleration time-histories for the field where the structures or equipment are installed, the general practice is to use the synthetic seismic acceleration time-histories, which are derived from the design seismic response spectra of the field, as the seismic excitation input data. However, from one specified design response spectrum indefinite solutions of acceleration time-histories can be derived depending on the values of the input parameters. Not all the derived synthetic time-histories can be used as seismic excitation input data. Only those which meet the acceptance criteria can be used. The factors (input parameters), which will affect the time-history solution from a specified seismic response spectrum, and the acceptance criteria are discussed

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

Directory of Open Access Journals (Sweden)

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.

This outstanding German foundation is actually the third one with the same name. Earlier two other Alexander von Humboldt Foundations consequently existed and they consist its pre-history, which is also shortly reviewed. The establishment of the present Foundation in 1953, its development and growth, its activities, information about the six presidents and five executive directors, as well as the main features, principles and guidelines are considered. During the last 60 years the Alexander von Humboldt Foundation became an important institution for the promotion of international research cooperation, which significantly influences the world science. It supported more than 27700 Humboldt fellows to carry out scientific research in Germany, and they form a large Humboldt family: a world-wide network. Large number Bulgarian Humboldt fellows are among the best scientists in Bulgaria.

2018-04-01

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.

Actual Problems of Kazakh History. Review of the Book by K.A. Pishchulina “Essays on the History of the Kazakh Khanate”

Directory of Open Access Journals (Sweden)

A.A. Galiyev

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.

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

International Nuclear Information System (INIS)

Uchiyama, Takafumi; Mitsuhashi, Ishi; Matsumoto, Tetsuo; Morishima, Kayoko; Tanzawa, Tomio

2016-01-01

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.)

2009-02-01

Full Text Available Abstract Background People with diabetes and peripheral neuropathy often do not implement the foot-care behavioural strategies that are suggested by many health professionals. The concept of self-efficacy has been shown to be an effective predictor of behaviour in many areas of health. This study investigated the relationships between foot-care self-efficacy beliefs, self-reported foot-care behaviour and history of diabetes-related foot pathology in people with diabetes and loss of protective sensation in their feet. Methods Ninety-six participants were included in this cross-sectional study undertaken in a regional city of Australia. All participants had diabetes and clinically diagnosed loss of protective sensation in their feet. The participants completed a self-report pen-paper questionnaire regarding foot-care self efficacy beliefs (the "Foot Care Confidence Scale" and two aspects of actual foot-care behaviour-preventative behaviour and potentially damaging behaviour. Pearson correlation coefficients were then calculated to determine the association between foot-care self-efficacy beliefs and actual reported foot-care behaviour. Multiple analysis of variance was undertaken to compare mean self-efficacy and behaviour subscale scores for those with a history of foot pathology, and those that did not. Results A small positive correlation (r = 0.2, p = 0.05 was found between self-efficacy beliefs and preventative behaviour. There was no association between self-efficacy beliefs and potentially damaging behaviour. There was no difference in self-efficacy beliefs in people that had a history of foot pathology compared to those that did not. Conclusion There is little association between foot-care self-efficacy beliefs and actual foot-care behaviour. The usefulness of measuring foot-care self-efficacy beliefs to assess actual self foot-care behaviour using currently available instruments is limited in people with diabetes and loss of protective

Natural history of chondroid skull base lesions - case report and review

International Nuclear Information System (INIS)

Schmidinger, A.; Rosahl, S.K.; Vorkapic, P.; Samii, M.

2002-01-01

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.)

History of Science and History of Philologies.

Science.gov (United States)

Daston, Lorraine; Most, Glenn W

2015-06-01

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.

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.

Deceased organ donors are routinely screened for behaviors that increase the risk of transmissible blood-borne viral (BBV) infection, but the impact of this information on organ donation and transplant outcome is not well documented. Our aim was to establish the impact of such behavior on organ donation and utilization, as well transplant recipient outcomes. We identified all UK deceased organ donors from 2003 to 2015 with a disclosed history of increased risk behavior (IRB) including intravenous drug use (IVDU), imprisonment and increased risk sexual behavior. Of 17 262 potential donors, 659 (3.8%) had IRB for BBV and 285 (1.7%) were seropositive for BBV, of whom half had a history of IRB (mostly IVDU [78.5%]). Of actual donors with IRB, 393 were seronegative for viral markers at time of donation. A history of recent IVDU was associated with fewer potential donors proceeding to become actual organ donors (64% vs 75%, P = 0.007). Donors with IRB provided 1091 organs for transplantation (624 kidneys and 467 other organs). Transplant outcome was similar in recipients of organs from donors with and without IRB. There were 3 cases of unexpected hepatitis C virus transmission, all from an active IVDU donor who was hepatitis C virus seronegative at time of donation, but was found to be viremic on retrospective testing. Donors with a history of IRB provide a valuable source of organs for transplantation with good transplant outcomes and there is scope for increasing the use of organs from such donors.

The role of history in science.

Science.gov (United States)

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.

Entering data onto paper-based forms, then digitizing them, is a traditional data-management method that might result in poor data quality, especially when the secondary data are incomplete, illegible, or missing. 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

CT bilaterally showed a cold area in the putamen of 5 infants with cerebral palsy who had had asphyxia at birth. The etiology was discussed, and 4 of the cases were clinically studied. All four patients had convulsive tetraplegia, or convulsive bilateral paralysis with the element of athetosis. Three of them had a history of infantile epilepsy, accompanied by abnormal ocular movement. Two patients with tetraplegia showed marked hypotonia of the trunk in ventral support (Landau). Impairment of the bilateral putamens in the abnormal muscle tone was inferred.

Approaches and Methods of Periodization in Literary History

2013-10-01

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. Because of multiple criteria of analysis and various literary genres, periodization in literary history is more complicated than that of general history. We can distinguish two approaches in periodization of literary history, although these can be used together: extrinsic or social-cultural approach (based on criteria extrinsic to literature and intrinsic or formalist approach (based on criteria intrinsic to literature. Then periodization in literary history can be formulated in different methods and may be based upon various criteria: chronological such as century, decade and year organic patterns of evolution great poets and writers literary emblems and evaluations of every period events, concepts and periods of general or political history analogy of literary history and history of ideas or history of arts approaches and styles of language dominant literary norms. These methods actually are used together and everyone has adequacy in special kind of literary history. In periodization of Persian contemporary literature, some methods and models current in periodization of poetry have been applied identically to periodization of prose. Periodization based upon century, decade and year is the simplest and most mechanical method but sometimes certain centuries in some countries have symbolic and stylistic meaning, and decades were used often for subdivisions of literary history, especially nowadays with fast rhythm of literary change.

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.”

The actual technological progress of NPPs

Florescu, Gheorghe; Popa, Adrian; Panaitescu, Valeriu

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.

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.

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.

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.

Pandit Vinay

2011-01-01

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.

Differential diagnosis and recovery of acute bilateral foot drop in a patient with a history of low back pain: A case report.

Science.gov (United States)

Lomaglio, Melanie; Canale, Bob

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.

Caustic-Side Solvent Extraction: Prediction of Cesium Extraction from Actual Wastes and Actual Waste Simulants

International Nuclear Information System (INIS)

Delmau, L.H.; Haverlock, T.J.; Sloop, F.V. Jr.; Moyer, B.A.

2003-01-01

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

Computing possible worlds in the history of modern astronomy

Osvaldo Pessoa Jr.

2016-09-01

Full Text Available http://dx.doi.org/10.5007/1808-1711.2016v20n1p117 As part of an ongoing study of causal models in the history of science, a counterfactual scenario in the history of modern astronomy is explored with the aid of computer simulations. After the definition of “linking advance”, a possible world involving technological antecedence is described, branching out in 1510, in which the telescope is invented 70 years before its actual construction, at the time in which Fracastoro actually built the first prototelescope. By using the principle of the closest possible world (PCP, we estimate that in this scenario the discovery of the elliptical orbit of Mars would by anticipated by only 28 years. The second part of the paper involves an estimate of the probability of the previous scenario, guided by the principle that the actual world is the mean (PAM and using computer simulations to create possible worlds in which the time spans between advances is varied according to a gamma distribution function. Taking into account the importance of the use of the diaphragm for the invention of the telescope, the probability that the telescope were built by 1538 for a branching time at 1510 is found to be smaller than 1%. The work shows that one of the important features of computational simulations in philosophy of science is to serve as a consistency check for the intuitions and speculations of the philosopher.

Kierkegaard’s Ethical Stage In Hegel’s Logical Categories: Actual Possibility, Reality And Necessity

Directory of Open Access Journals (Sweden)

María J. Binetti

2007-12-01

Full Text Available During decades, the history of philosophy has kept Kierkegaardrsquo;s and Hegelrsquo;s thought apart, and their long-standing opposition has swept through the speculative greatness of Kierkegaardian existentialism and the existential power of Hegelian philosophy. In contrast to such unfortunate misinterpretation, this article aims at showing the deep convergence that relates interiorly the Kierkegaardian ethical stage with the most important Hegelian logic categories. Kierkegaard and Hegel conceive of the idea as the real power of subjective becoming, and the existence as the actual concretion of the ideal. To both of them, the pure emeneacute;rgeia/em of freedom, which starts in the abstract and aesthetical possibility of the subjective immediacy, realizes itself as the actual concretion of finitude, assuming time and contingency by the eternal and necessary force of duty. The Kierkegaardian repetition is nothing but this powerful idea, mediating the flux of finite differences in the eternal identity of subject. However, for Kierkegaard as well as for Hegel there is an absolute contradiction, which promotes the overcoming of ethics.

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.

Kalantar-Hormozi, Abdoljalil

2013-03-01

 Although the exact time of performing plastic surgery is not addressed in the medical and historical literature, it can be supposed that these surgical procedures have a long and fascinating history.  Recent excavations provided many documents regarding the application of medical instruments, surgical and even reconstructive procedures during the pre-historic and ancient periods. Actually, there is no historical definite time-zone separating general and cosmetic operations in the pre-modern time; however, historically there have been many surgeons who tried to perform reconstructive procedures during their usual medical practice. This article presents a brief look at the history of plastic surgery form the ancient to the contemporary era, with a special focus on Iran.

Vietnam military service history and prostate cancer

Directory of Open Access Journals (Sweden)

Fritschi Lin

2006-03-01

Full Text Available Abstract Background Three decades after US and Australian forces withdrew from Vietnam, there has been much public interest in the health consequences of service in Vietnam. One controversial question is whether the risk of prostate cancer amongst Vietnam veterans is increased. This paper examines relationships between military history, family history and risk of prostate cancer in a population-based case control study. Methods Cases were selected from the Cancer Registry of Western Australia as incident cases of histologically-confirmed prostate cancer, and controls were age-matched and selected from the Western Australian electoral roll. Study participants were asked to report any military service history and details about that service. Results Between January 2001 and September 2002, 606 cases and 471 controls aged between 40–75 years were recruited. An increased prostate cancer risk was observed in men reporting they were deployed in Vietnam although this was not statistically significant (OR = 2.12; 95% CI 0.88–5.06. An increased risk was also observed in men reporting prostate cancer in fathers (OR = 1.90; 95% CI 1.20–3.00 or brothers (OR = 2.05; 95% CI 1.20–3.50 diagnosed with prostate cancer. Conclusion These findings support a positive association between prostate cancer and military service history in the Vietnam war and a first degree relative family history of prostate cancer.

Radon remedial techniques in buildings - analysis of French actual cases

International Nuclear Information System (INIS)

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

The Somerton man : an unsolved history

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

The 30-year natural history of AIDS disease is presented from the first clinical cases reported in 1981 to the identification of the HIV as the etiological agent of the disease. The priority dispute between Robert C. Gallo and Luc Montagnier over the discovery of the human immunodeficiency virus is briefly addressed. The final confirmation of the French priority was provided by the fact that the Nobel Prize in Medicine 2008 was awarded to Luc Montagnier and Francoise Barré--Sinoussi from the Pasteur Institute in Paris.

Experience with a pharmacy technician medication history program.

Science.gov (United States)

Cooper, Julie B; Lilliston, Michelle; Brooks, DeAnne; Swords, Bruce

2014-09-15

The implementation and outcomes of a pharmacy technician medication history program are described. An interprofessional medication reconciliation team, led by a clinical pharmacist and a clinical nurse specialist, was charged with implementing a new electronic medication reconciliation system to improve compliance with medication reconciliation at discharge and capture compliance-linked reimbursement. The team recommended that the pharmacy department be allocated new pharmacy technician full-time-equivalent positions to assume ownership of the medication history process. Concurrent with the implementation of this program, a medication history standard was developed to define rules for documentation of what a patient reports he or she is actually taking. The standard requires a structured interview with the patient or caregiver and validation with outside sources as indicated to determine which medications to document in the medication history. The standard is based on four medication administration category rules: scheduled, as-needed, short-term, and discontinued medications. The medication history standard forms the core of the medication history technician training and accountability program. Pharmacy technicians are supervised by pharmacists, using a defined accountability plan based on a set of medical staff approved rules for what medications comprise a best possible medication history. Medication history accuracy and completeness rates have been consistently over 90% and rates of provider compliance with medication reconciliation rose from under 20% to 100% since program implementation. A defined medication history based on a medication history standard served as an effective foundation for a pharmacy technician medication history program, which helped improve provider compliance with discharge medication reconciliation.

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.

Design spectra development considering short time histories

International Nuclear Information System (INIS)

Weiner, E.O.

1983-01-01

Two separate programs, MODQKE and MDOF, were written to provide a capability of obtaining equipment spectra from design spectra. MODQKE generates or modifies acceleration histories to conform with design spectra pertaining to, say, a foundation. MDOF is a simple linear modal superposition program that solves for equipment support histories using the design spectra conforming histories as input. Equipment spectra, then, are obtained from the support histories using MODQKE. MODQKE was written to modify or provide new histories with special attention paid to short seismic records. A technique from the open literature was borrowed to generate an initial history that approximates a given response spectrum. Further refinement is done with smoothing cycles in which several correction signals are added to the history in a way that produces a least squares fit between actual and prescribed spectra. Provision is made for history shaping, a baseline correction, and final scaling. MODQKE performance has been demonstrated with seven examples having zero to ten percent damping ratios, and 2.5 seconds to 20 seconds durations and a variety of target spectra. The examples show the program is inexpensive to use. MDOF is a simple modal superposition program. It has no eigensolver, and the user supplies mode shapes, frequencies, and participation factors as input. Floor spectra can be generated from design spectra by using a history from MODQKE that conforms to the design spectrum as input to MDOF. Floor motions from MDOF can be fed back to MODQKE without modification to obtain the floor spectra. A simple example is given to show how equipment mass effects can be incorporated into the MDOF solution. Any transient solution capability can be used to replace MDOF. For example, a direct transient approach may be desirable if both the equipment and floor structures are to be included in the model with different damping fractions. (orig./HP)

Actual imaging time in fetal MRI

International Nuclear Information System (INIS)

Brugger, Peter C.; Prayer, Daniela

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.

Do Emotions Expressed Online Correlate with Actual Changes in Decision-Making?: The Case of Stock Day Traders.

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.

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

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.

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.

1997-01-01

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

[Variation characteristics and influencing factors of actual evapotranspiration under various vegetation types: A case study in the Huaihe River Basin, China.

Wu, Rong Jun; Xing, Xiao Yong

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.

Detecting space-time cancer clusters using residential histories

Science.gov (United States)

Jacquez, Geoffrey M.; Meliker, Jaymie R.

2007-04-01

Methods for analyzing geographic clusters of disease typically ignore the space-time variability inherent in epidemiologic datasets, do not adequately account for known risk factors (e.g., smoking and education) or covariates (e.g., age, gender, and race), and do not permit investigation of the latency window between exposure and disease. Our research group recently developed Q-statistics for evaluating space-time clustering in cancer case-control studies with residential histories. This technique relies on time-dependent nearest neighbor relationships to examine clustering at any moment in the life-course of the residential histories of cases relative to that of controls. In addition, in place of the widely used null hypothesis of spatial randomness, each individual's probability of being a case is instead based on his/her risk factors and covariates. Case-control clusters will be presented using residential histories of 220 bladder cancer cases and 440 controls in Michigan. In preliminary analyses of this dataset, smoking, age, gender, race and education were sufficient to explain the majority of the clustering of residential histories of the cases. Clusters of unexplained risk, however, were identified surrounding the business address histories of 10 industries that emit known or suspected bladder cancer carcinogens. The clustering of 5 of these industries began in the 1970's and persisted through the 1990's. This systematic approach for evaluating space-time clustering has the potential to generate novel hypotheses about environmental risk factors. These methods may be extended to detect differences in space-time patterns of any two groups of people, making them valuable for security intelligence and surveillance operations.

Probabilistic seismic history matching using binary images

Science.gov (United States)

Davolio, Alessandra; Schiozer, Denis Jose

2018-02-01

Currently, the goal of history-matching procedures is not only to provide a model matching any observed data but also to generate multiple matched models to properly handle uncertainties. One such approach is a probabilistic history-matching methodology based on the discrete Latin Hypercube sampling algorithm, proposed in previous works, which was particularly efficient for matching well data (production rates and pressure). 4D seismic (4DS) data have been increasingly included into history-matching procedures. A key issue in seismic history matching (SHM) is to transfer data into a common domain: impedance, amplitude or pressure, and saturation. In any case, seismic inversions and/or modeling are required, which can be time consuming. An alternative to avoid these procedures is using binary images in SHM as they allow the shape, rather than the physical values, of observed anomalies to be matched. This work presents the incorporation of binary images in SHM within the aforementioned probabilistic history matching. The application was performed with real data from a segment of the Norne benchmark case that presents strong 4D anomalies, including softening signals due to pressure build up. The binary images are used to match the pressurized zones observed in time-lapse data. Three history matchings were conducted using: only well data, well and 4DS data, and only 4DS. The methodology is very flexible and successfully utilized the addition of binary images for seismic objective functions. Results proved the good convergence of the method in few iterations for all three cases. The matched models of the first two cases provided the best results, with similar well matching quality. The second case provided models presenting pore pressure changes according to the expected dynamic behavior (pressurized zones) observed on 4DS data. The use of binary images in SHM is relatively new with few examples in the literature. This work enriches this discussion by presenting a new

Full Text Available In The City of Ladies and Bell in Campo, Christine de Pizan and Margaret Cavendish imagine women’s participation to war as a metaphor of the sexual conflict that they must fight in order to conquer their visibility in history. While Pizan rewrites history from women’s stand point and acknowledges the universal value of sexual difference for the plan of salvation, Cavendish moves within a modern frame and thinks history as the result of human action. In both cases, the tale of women’s participation to war allows criticizing the moral and normative implications of «nature».

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

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.

[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.

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

Davies, M J

2000-11-01

The notion of "region" can be a valuable analytical tool in the writing of Canadian medical history. This article explores themes in the history of British Columbia that link medicine and regional development. Employing a historiographical sweep from the colonial period to the 1970s, the author considers doctors and imperialism, medical practice and the economy, and the relationship between metropolis and periphery in shaping medical institutions and medical culture in the western province. The intent of the piece is to stimulate thought about the potential of introducing the sense of place into regional medical history in Canada.

History of physical terms: ‘energy’

Science.gov (United States)

Frontali, Clara

2014-09-01

Difficulties encountered by teachers in giving a definition of the term ‘energy’, and by students in grasping its actual meaning, reflect the lengthy process through which the concept eventually came to maturity around 1850. Tracing the history of this process illuminates the different aspects covered by the term and shows the important role played by advancements in animal physiology in the concept’s elaboration. A unique example of cross-fertilization between historically separate fields, the history of the studies on animal heat, is recounted here. The recount starts from the early experiments by Boyle and Hooke on the effect of void on living beings and from Lavoisier’s revolutionary interpretation of respiration as a ‘slow combustion’ process, touching on the contributions by Spallanzani, von Humboldt and Liebig. It ends with the first enunciation of an energy conservation law by two German physicians, Meyer and Helmholtz, in advance of the elaboration of a coherent thermodynamic framework by Kelvin.

Full Text Available The history of beriberi is an example of national pride, different social classes, research efforts and also luck. All histories have their main protagonists. In this case, perhaps the most significant people were Christiaan Eijkman, William Fletcher and Kanehiro Takaki. Infection, toxicity and feeding, among other factors, were the starting points to support the initial etiopathogenic bases of the disease. The experimental and epidemiological work of these authors gave the key about the cause of beriberi and its effective treatment. As in the case of scurvy, the mystery was solved not without very hard work and many previous mistakes.

Family History Is a Risk Factor for COPD

Hokanson, John E.; Lynch, David A.; Washko, George R.; Make, Barry J.; Crapo, James D.; Silverman, Edwin K.

2011-01-01

Background: Studies have shown that family history is a risk factor for COPD, but have not accounted for family history of smoking. Therefore, we sought to identify the effects of family history of smoking and family history of COPD on COPD susceptibility. Methods: We compared 821 patients with COPD to 776 control smokers from the Genetic Epidemiology of COPD (COPDGene) Study. Questionnaires captured parental histories of smoking and COPD, as well as childhood environmental tobacco smoke (ETS) exposure. Socioeconomic status was defined by educational achievement. Results: Parental history of smoking (85.5% case patients, 82.9% control subjects) was more common than parental history of COPD (43.0% case patients, 30.8% control subjects). In a logistic regression model, parental history of COPD (OR, 1.73; P < .0001) and educational level (OR, 0.48 for some college vs no college; P < .0001) were significant predictors of COPD, but parental history of smoking and childhood ETS exposure were not significant. The population-attributable risk from COPD family history was 18.6%. Patients with COPD with a parental history had more severe disease, with lower lung function, worse quality of life, and more frequent exacerbations. There were nonsignificant trends for more severe emphysema and airway disease on quantitative chest CT scans. Conclusions: Family history of COPD is a strong risk factor for COPD, independent of family history of smoking, personal lifetime smoking, or childhood ETS exposure. Although further studies are required to identify genetic variants that influence COPD susceptibility, clinicians should question all smokers, especially those with known or suspected COPD, regarding COPD family history.

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.

Full Text Available Gränsöverskridande Nordisk Undervisning/Utdanelse (GNU, meaning Cross-Border Nordic Education, the larger Nordic project, under which this case study was carried out, aims at developing innovative, cross-border teaching models in different subject domains in elementary school, including mathematics, language, science, social studies and history. 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. However, achieving subject-specific goals in history

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.

Inamura, Tomoaki

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.

Geomechanics in hard rock mining-Lessons from two case histories

International Nuclear Information System (INIS)

Heuze, F.E.

1982-01-01

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

The reliability of pre-travel history to decide on appropriate counseling and vaccinations: a prospective study.

2012-01-01

Although medical and travel plans gathered from pre-travel interviews are used to decide the provision of specific pre-travel health advice and vaccinations, there has been no evaluation of the relevance of this strategy. In a prospective study, we assessed the agreement between pre-travel plans and post-travel history and the effect on advice regarding the administration of vaccines and recommendations for malaria prevention. We included prospectively all consenting adults who had not planned an organized tour. Pre- and post-travel information included questions on destination, itineraries, departure and return dates, access to bottled water, plan of bicycle ride, stays in a rural zone, and close contact with animals. The outcomes measured included: agreement between pre- and post-travel itineraries and activities; and the effect of these differences on pre-travel health recommendations, had the traveler gone to the actual versus intended destinations for actual versus intended duration and activities. Three hundred and sixty-five travelers were included in the survey, where 188 (52%) were males (median age 38 years). In 81(23%) travelers, there was no difference between pre- and post-travel history. Disagreement between pre- and post-travel history were the highest for stays in rural zones or with local people (66% of travelers), close contact with animals (33%), and bicycle riding (21%). According to post-travel history, 125 (35%) travelers would have needed rabies vaccine and 9 (3%) typhoid fever vaccine. Potential overprovision of vaccine was found in travelers. A change in the malaria prescription would have been recommended in 18 (5%) travelers. Pre-travel history does not adequately reflect what travelers do. However, difference between recommendations for the actual versus intended travel plans was only clinically significant for the need for rabies vaccine. Particular attention during pre-travel health counseling should focus on the risk of rabies, the

“Cinematic” Gravity’s Rainbow: Indiscernibility of the Actual and the Virtual

Full Text Available Acknowledging that all media interpenetrate without any one being privileged as original, this paper focuses on the influence and omnipresence of screen technologies, cinematography in particular, asserting its capacities to act as a dominant technological and cultural force, which surveys and controls the economy, affects human consciousness, and implements its own ideologically tainted reality. More specifically, the analysis demonstrates the impact of cinematography within Thomas Pynchon’s Gravity’s Rainbow, emphasizing intermedial reflexivity from screen to paper, its unfolding and animation, representations and mutations, but also the notion that virtuality dominates actuality (Virilio, The Vision 63, or, in Deleuze’s terms, the two coalesce within the crystal-image, for the real and the imaginary, the actual and the virtual, although distinct, are indiscernible (Deleuze, Cinema 2 68-69. The study is grounded in Paul Virilio’s theoretical framework and his criticism of the colonization of the real by the virtual, and in Gilles Deleuze’s account on cinematic taxonomy and how cinematography partakes in the emergence of a new notion of reality and history. By appropriating, repurposing, and reshaping the techniques, forms, and contents of cinematography, and at the same time being critical of its effects, Pynchon uses paper surface for transition of his ideas, validating the repercussions of intermediation as a cultural force and unveiling literature’s performativity, its ability to shelter/entertain the “cinematic,” which in turn revolutionizes and animates fiction.

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

International Nuclear Information System (INIS)

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

On the actual controlling of standards concerning the 'fast breeder reactor'

If the decision of the OVG Muenster to present the case to the Federal Constitutional Court asking whether Article 7 of the atomic energy law corresponds to the constitution or not, as far as the article allows the licensing of a fast breeder reactor, two problems arise: The legal question in how far the actual controlling of standards is to be preceeded by a statement of facts given by the court of first instance, and the problem behind concerning the responsibility of decision. The Federal Constitutional Court should accept the responsibility of decision to be borne by it. (orig.) [de

Dhalla, Shayesta; Poole, Gary

2014-02-01

An examination of actual HIV vaccine trials can contribute to an understanding of motivators for participation in these studies. Analysis of these motivators reveals that they can be categorized as social and personal benefits. Social benefits are generally altruistic, whereas personal benefits are psychological, physical, and financial. In this systematic review, the authors performed a literature search for actual preventive HIV vaccine trials reporting motivators to participation. Of studies conducted in the Organization for Economic Co-operation and Development (OECD) countries, the authors retrieved 12 studies reporting on social benefits and seven reporting on personal benefits. From the non-OECD countries, nine studies reported on social benefits and eight studies on personal benefits. Social benefits were most frequently described on macroscopic, altruistic levels. Personal benefits were most frequently psychological in nature. Rates of participation were compared between the OECD and the non-OECD countries. Knowledge of actual motivators in specific countries and regions can help target recruitment in various types of actual HIV vaccine trials.

Electrokinetic enhanced bioventing of gasoline in clayey soil: A case history

International Nuclear Information System (INIS)

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

Science Fairs and Observational Science: A Case History from Earth Orbit

Science.gov (United States)

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.

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.

Post-Conflict History Education in Finland, South Africa and Bosnia-Herzegovina

Directory of Open Access Journals (Sweden)

Sirkka Ahonen

2013-08-01

Full Text Available A post-conflict society tends to get locked in a history war. As the practice of history in its broad sense is a moral craft, representations of guilt and victimhood prevail in social memory. The representations are often bolstered by mythical references, wherefore deconstruction of myths is expected from history education for the purposes of post-conflict reconciliation. This article deals with the post-conflict uses of history in Finland, South Africa and Bosnia-Herzegovina. The three cases constitute examples of a class war, a race conflict and an ethno-religious armed clash. The memory politics and history curricula differ between the cases. Their comparison indicates, how far an imposition of one ´truth´, a dialogue of two ´truths´ and segregation of different memory communities are feasible strategies of post-conflict history education. The article suggests that history lessons can be an asset instead of a liability in the pursuit of reconciliation.

Comparative Analysis of Liability Cases for Bankruptcies of Financial Institutions

Full Text Available The bankruptcy of the fourth largest investment bank in the world Lehman Brothers Holdings Inc. in 2008 remains the largest bankruptcy in the history of United States. This bankruptcy is viewed as a turning point in the Global Financial Crisis. Paradoxically, even though the financial system had many safeguards (auditors, audit committees, the board of directors, credit rating agencies, government supervisors whose purpose was to inform the investing public about the actual financial situation of the institution, Lehman Brothers bankruptcy came as a shock to financial markets across the globe revealing that many of the “gatekeepers” failed. Comparative analysis of liability cases after bankruptcies of Lehman Brothers and financial institutions in Lithuania shows that contrary to Lehman’s case, the demise of financial institutions in Lithuania cannot be attributed to sub-prime mortgages caused financial crisis, real estate market fluctuations or any other external variable. Problems are related to weak supervision, inefficient regulation, and common unethical behavior in the financial sector.

Focus: global currents in national histories of science: the "global turn" and the history of science in Latin America.

Science.gov (United States)

McCook, Stuart

2013-12-01

The "global turn" in the history of science offers new ways to think about how to do national and regional histories of science, in this case the history of science in Latin America. For example, it questions structuralist and diffusionist models of the spread of science and shows the often active role that people in Latin America (and the rest of the Global South) played in the construction of "universal" scientific knowledge. It suggests that even national or regional histories of science must be situated in a global context; all too often, such histories have treated global processes as a distant backdrop. At the same time, historians need to pay constant attention to the role of power in the construction of scientific knowledge. Finally, this essay highlights a methodological tool for writing globally inflected histories of science: the method of "following".

Full Text Available OBJECTIVES: Plague remains a public health concern worldwide, particularly in old foci. Multiple epidemics of this disease have been recorded throughout the history of Iran. Despite the long-standing history of human plague in Iran, it remains difficult to obtain an accurate overview of the history and current status of plague in Iran. METHODS: In this review, available data and reports on cases and outbreaks of human plague in the past and present in Iran and in neighboring countries were collected, and information was compiled regarding when, where, and how many cases occurred. RESULTS: This paper considers the history of plague in Persia (the predecessor of today’s Iran and has a brief review of plague in countries in the World Health Organization Eastern Mediterranean Region, including a range of countries in the Middle East and North Africa. CONCLUSIONS: Since Iran has experienced outbreaks of plague for several centuries, neighboring countries have reported the disease in recent years, the disease can be silent for decades, and the circulation of Yersinia pestis has been reported among rodents and dogs in western Iran, more attention should be paid to disease monitoring in areas with previously reported human cases and in high-risk regions with previous epizootic and enzootic activity.

The effect of dietary habits on colorectal cancer (CRC) risk may be modified by a family history of CRC. We analyzed data from an Italian case-control study, including 1953 CRC cases and 4154 controls. Odds ratios (OR) and 95% confidence intervals (CI) for combined categories of family history and tertiles of two a posteriori dietary patterns were derived using multiple logistic regression models. Compared with individuals without family history and in the lowest tertile category of the 'starch-rich' pattern, the ORs of CRC were 1.38 (95% CI: 1.19-1.61) for the group without family history and in the highest tertile, 2.89 (95% CI: 2.30-3.64) for the one with family history and in the lowest tertile, and 4.00 (95% CI: 3.03-5.27) for the one with family history and in the highest tertile. Compared with individuals without family history and in the highest tertile of the 'vitamins and fiber' pattern, the ORs were 1.29 (95% CI: 1.12-1.48) for the group without family history and in the lowest tertile, 2.89 (95% CI: 2.30-3.64) for the one with family history and in the highest tertile, and 3.74 (95% CI: 2.85-4.91) for the one with family history and in the lowest tertile. Family history of CRC and 'starch-rich' or 'vitamins and fiber' patterns has an independent effect on CRC risk in our population. However, as having a family history plausibly implies shared environmental and/or genetic risk factors, our results could not exclude that dietary habits can modify genetic susceptibility to CRC.

Bohmian histories and decoherent histories

International Nuclear Information System (INIS)

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

To compare and contrast subjective perceptions with objective compliance of the impact of the 2010 Centers for Medicare and Medicaid Service updates of the Medicare Benefit Policy Manual. Cross-sectional survey. An electronic survey was sent by the Uniform Data System for Medical Rehabilitation to all enrolled inpatient rehabilitation facility subscribers (n = 817). The survey was sent April 15, 2011, and responses were tabulated if they were received by May 15, 2011. Comparing and contrasting of the subjective perception to objective evaluation and/or compliance with the Medicare Benefit Policy Manual on case mix index, length of stay, admissions by diagnostic category as well as perception of preadmission screening, postadmission evaluation, plan of care, and interdisciplinary conferencing. Twenty-five percent of the 817 facilities responded, for a total of 209 responses. Complete data were present in 148 of the respondents. For most diagnostic categories, perception of change did not mirror reality of change; neither did the perception between change in case mix index and length of stay. Perception did match reality in stroke and multiple trauma cases; respondents perceived an increase in admissions for the 2 impairments, and there was an overall increase in reality. Comparison with actual data identified that gaps exist between diagnostic category perceptions and actual diagnostic category admission performance. Regulations such as the 75%-60% rule and audit focus on non-neurologic conditions as well as actual inpatient rehabilitation facility program payment reports may have influenced respondents perceptions to change associated with the Medicare Benefit Policy Manual modifications. This disparity between perception and actual data may have implications for programmatic planning, forecasting, and resource allocation.

Water conservation by 3 R's - case histories of Heavy Water Plants

International Nuclear Information System (INIS)

Agarwal, A.K.; Hiremath, S.C.

2005-01-01

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)

Successful field implementation of novel cementing solution for ISC wells : case histories

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.

The actual goals of geoethics

Nemec, Vaclav

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

This report discusses and analyzes the analysis reliability of dynamic analysis according to the type of input time history when using commercial FEM analysis code ANSYS. The dynamic analysis using ANSYS with displacement time history, and GT/STRUDL with displacement time history for the same model were carried out and compared. The ANSYS results with displacement time history were more conservative than that with acceleration time history, and showed an unstable characteristic depending on the input directions. The results of analysis using ANSYS with acceleration time history. To review the effect on the analysis for the NSSS structures, CEDM seismic analysis using ANSYS was done. The input time history is comprised of SSE, OBE, and BLPB cases. The comparisons are made by the acceleration floor response spectra of each case obtained after postprocessing of analysis results. The seismic analysis with displacement time history exhibited more conservative results than those with acceleration time history. In conclusion, a time history analysis using ANSYS with displacement time history may give overly conservative results. Hence displacement time history option in ANSYS requires a careful consideration, and it is recommended to use the acceleration time history option if possible. 6 tabs., 22 figs., 7 refs.

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.

Electrodermal responses to implied versus actual violence on television.

Kalamas, A D; Gruber, M L

1998-01-01

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.

Towards A New Digital Historicism? Doing History In The Age Of Abundance

Directory of Open Access Journals (Sweden)

Andreas Fickers

2012-03-01

Full Text Available This article argues that the contemporary hype in digitization and dissemination of our cultural heritage – especially of audiovisual sources – is comparable to the boom of critical source editions in the late 19th century. But while the dramatic rise of accessibility to and availability of sources in the 19th century went hand in hand with the development of new scholarly skills of source interpretation and was paralleled by the institutionalization of history as an academic profession, a similar trend of an emerging digital historicism today seems absent. This essay aims at reflecting on the challenges and chances that the discipline of history – and the field of television history in particular – is actually facing. It offers some thoughts and ideas on how the digitization of sources and their online availability affects the established practices of source criticism. 

Holocene eruption history in Iceland - Eruption frequency vs. Tephra layer frequency

Science.gov (United States)

Oladottir, B. A.; Larsen, G.

2012-12-01

preservation conditions at a particular location can be good at one time but poor at another, e.g. after deposition of metre thick tephra suffocating the vegetation. Several locations must be studied in order to prevent localised bias in the data. A good approximation of how many tephra layers are lost from the soil record is vital to estimate actual eruption frequency in prehistoric time from the tephra layer frequency. One way to obtain that information is to compare the historical tephra record from the soil to all available records of historical volcanic activity, in particular written records and, in case of volcanoes within ice caps, the tephra stratigraphy preserved in the ice. The ratio between preserved historical tephra layers and known historical eruptions from other records provides a preservation ratio that can be used with the tephra layer frequency to estimate the actual eruption frequency of a volcano, assuming that the preservation is the same during historical and prehistoric time. The preservation ratio of Grímsvötn and Bárdarbunga tephra calculated from soil sections around Vatnajökull shows that only one out of four eruptions in these volcanoes is recorded in the soil.

The medial meniscus is injured much more than the lateral meniscus. Because the medial meniscus is much larger in diameter, is thinner in its periphery and narrower in body than the lateral meniscus, and dose not attach to either cruciate ligament. We evaluated correlations with sites of tear and history of trauma. We reviewed retrospectively in 43 patients with meniscal tears on MR(51 cases) and correlated them with history of trauma. The most common site of injury was the posterior horn of the medial meniscuc(32/51), but high incidence of lateral meniscal tear compared with previous reports was seen. In the cases which had history of trauma, the posterior horn of medial meniscus was most commonly injured(26/34) and 5 meniscal tears were combined with meniscal tear in the other site. The tear in the anterior horn of the medial meniscus was seen only in a patient which had history of trauma and combined with meniscal tear in the other site. But in the meniscal tears without definite history of trauma, the incidence of meniscal tear was different from the meniscal tear with history of trauma. The incidence of lateral meniscal tear(11/17) was higher than medial meniscal tear and the posterior horn of lateral meniscus was commonly injured. We concluded that the medial meniscus was commonly injured, especially posterior horn, but in the cases which had no definite history of trauma, the lateral meniscus was commonly injured. An awareness of prevalent site of meniscal injuries may be helpful in the diagnostic interpretation of MR imaging of knee

2018-05-24

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.

Full Text Available In the given article we analyze the representation of the period from the recent history- Socialist Yugoslavia- through the case study of national history museum and private exhibition. Although both of the analyzed objects are located in Ljubljana, the metastories which they construct and display are based on the different cultural patterns. We compare the differences of the narratives being used by the private and state institution and apply the visual analysis method together with semi-structured interviews for these purposes. As a result of our research, we show how differs ‘official narration’ compared to the so-called ‘Yugonostalgic’ or ‘Titostalgic’ viewpoint and describe their main characteristics.

Actual conditions of radiation control in radioisotope utilization field

International Nuclear Information System (INIS)

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.)

Thermal History and Crystallinity of Sheet Intrusions

Science.gov (United States)

Whittington, A. G.; Nabelek, P. I.; Hofmeister, A.

2011-12-01

Magma emplaced in a sheet intrusion has two potential fates: to crystallize, or quench to glass. Rapidly chilled sheet margins are typically glassy or microcrystalline, while interiors are coarser-grained. The actual textures result from a combination of thermal history and crystallization kinetics, which are related by various feedback mechanisms. The thermal history of cooling sheet intrusions is often approximated using the analytical solution for a semi-infinite half-space, which uses constant thermal properties such as heat capacity (CP), thermal diffusivity (D) and thermal conductivity (k = DρCP), where ρ is density. In reality, both CP and D are strongly T-dependent for glasses and crystals, and melts have higher CP and lower D than crystals or glasses. Another first-order feature ignored in the analytical solution is latent heat of crystallization (ΔHxt), which can be implemented numerically as extra heat capacity over the crystallization interval. For rhyolite melts, D is ~0.5 mm2s-1 and k is ~1.5 Wm-1K-1, which are similar to those of major crustal rock types and granitic protoliths at magmatic temperatures, suggesting that changes in thermal properties accompanying partial melting of the crust should be relatively minor. Numerical models of hot (~920°C liquidus for 0.5 wt.% H2O) shallow rhyolite intrusions indicate that the key difference in thermal history between bodies that quench to obsidian, and those that crystallize, results from the release of latent heat of crystallization, which enables bodies that crystallize to remain at high temperatures for much longer times. The time to solidification is similar in both cases, however, because solidification requires cooling through the glass transition (Tg ~620°C) in the first case, and cooling only to the solidus (~770°C) in the second. For basaltic melts, D is ~0.3 mm2s-1 and k is ~1.0 Wm-1K-1, compared to ~0.6 mm2s-1 and 2.5 Wm-1K-1 for crystalline basalt or peridotite at magmatic temperatures

Family history is considered a risk factor for age-related macular degeneration (AMD). With the advent of effective therapy for the disease, the importance of family history merits further investigation. This study quantifies the risk associated with family history, first, by a case-control study of reported family history and, second, by examining the siblings of AMD cases. The authors recruited cases with advanced AMD, spouses and siblings. All subjects were carefully phenotyped. Clinical findings in the siblings were compared with spouses. Information about family history was collected. The ORs for reported family history of AMD were calculated. Analyses were adjusted for age, smoking and genotype. 495 AMD cases, 259 spouses and 171 siblings were recruited. The OR for AMD was 27.8 (CI 3.8 to 203.0; p=0.001) with a reported family history of an affected parent and 12.0 (CI 3.7 to 38.6; p<0.0001) with a history of an affected sibling. ORs adjusted for age and smoking were higher. Examination of siblings confirmed their increased risk with 23% affected by AMD and an OR of 10.8 (4.5 to 25.8; p<0.0001). Adjusting for age increased the OR to 16.1 (6.2 to 41.8). The risk of AMD is greatly increased by having an affected first-degree relative. Those at risk need to be made aware of this and AMD patients should advise siblings and children to seek prompt ophthalmological advice if they develop visual symptoms of distortion or reduced vision.

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.

Association Between Cleft Lip and/or Cleft Palate and Family History of Cancer: A Case-Control Study.

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.

Motion sickness history, food neophobia, and sensation seeking.

Science.gov (United States)

Alley, Thomas R; Willet, Kathleen A; Muth, Eric R

2006-06-01

Motion sickness is believed to be caused by conflicting sensory signals, a situation that mimics the effects of ingesting certain toxins. Thus, one might suspect that individuals who have experienced a relatively high frequency of motion sickness may be particularly vigilant about avoiding anything that produces nausea, induding potentially nauseating toxins. Consequently, they may be more resistant to trying new foods, i.e., be more food neophobic, since unfamiliar foods can have unexpected adverse effects due to toxins or allergens. Likewise, many highly stimulating experiences can trigger motion sickness, so individuals who are more susceptible may be more prone to avoid such experiences, i.e., be less sensation seeking. Finally, it was expected that food neophobia would be more frequent in individuals low on sensation seeking tendencies. Self-reported motion sickness history in 308 adults (M= 18.8 yr.; SD = 1.6) was correlated with scores on the Arnett Inventory of Sensation Seeking and the Food Neophobia Scale. As predicted, greater history of motion sickness was associated with lower Sensation Seeking scores. Food Neophobia was not correlated with motion sickness history but, as expected, was negatively correlated (r = -.42) with scores on Sensation Seeking. Further research is recommended that measures actual sensitivity to motion sickness.

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.

A History-based Estimation for LHCb job requirements

Science.gov (United States)

Rauschmayr, Nathalie

2015-12-01

The main goal of a Workload Management System (WMS) is to find and allocate resources for the given tasks. The more and better job information the WMS receives, the easier will be to accomplish its task, which directly translates into higher utilization of resources. Traditionally, the information associated with each job, like expected runtime, is defined beforehand by the Production Manager in best case and fixed arbitrary values by default. In the case of LHCb's Workload Management System no mechanisms are provided which automate the estimation of job requirements. As a result, much more CPU time is normally requested than actually needed. Particularly, in the context of multicore jobs this presents a major problem, since single- and multicore jobs shall share the same resources. Consequently, grid sites need to rely on estimations given by the VOs in order to not decrease the utilization of their worker nodes when making multicore job slots available. The main reason for going to multicore jobs is the reduction of the overall memory footprint. Therefore, it also needs to be studied how memory consumption of jobs can be estimated. A detailed workload analysis of past LHCb jobs is presented. It includes a study of job features and their correlation with runtime and memory consumption. Following the features, a supervised learning algorithm is developed based on a history based prediction. The aim is to learn over time how jobs’ runtime and memory evolve influenced due to changes in experiment conditions and software versions. It will be shown that estimation can be notably improved if experiment conditions are taken into account.

Maslow's need hierarchy and model of the self-actualizing personality are reviewed and criticized. The definition of self-actualization is found to be confusing, and the gratification of all needs is concluded to be insufficient to explain self-actualization. Therefore the theory is reconstructed on the basis of a second-order, cognitive-systemic framework. A hierarchy of basic needs is derived from the urgency of perturbations which an autonomous system must compensate in order to maintain i...

Full Text Available The Five-Factor Model of personality, which includes dimensions energy, agreeableness, conscientiousness, emotional stability, and openness, gained a growing acceptance by personality researchers. In the present study the actual personality characteristics of physical educators and the personality profile of an ideal (according to subjective evaluations of experts physical educator were investigated. The aim of the study was to examine differences between profiles of actual and preferred personality characteristics and to present differences in personality characteristics between male and female physical educators of different ages. The study included 76 (40 male, 36 female 24 to 58 year-old physical educators (mean age 39.7 years. 34 experts from the field of sport, physical education, and kinesiology evaluated the preferred personality structure of an ideal physical educator. The Big Five Observer (BFO was used to assess actual and preferred personality structures. These results show that the actual personality profile of physical educators is described with all five moderately high dimensions, which is relatively congruent with the social type from Holland's typology, characteristic of educators. In comparison with participants, an ideal physical educator should have equally expressed agreeableness, while other four dimensions should be highly expressed. Gender differences in energy and agreeableness (women have higher results in both dimensions were found significant. No significant age differences in the personality structure were obtained by a cross-sectional comparison.

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)

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

Family history is an important risk factor for breast cancer incidence, but the parameters conventionally used to categorize it are based solely on numbers and/or ages of breast cancer cases in the family and take no account of the size and age-structure of the woman's family. Using data from the Generations Study, a cohort of over 113,000 women from the general UK population, we analyzed breast cancer risk in relation to first-degree family history using a family history score (FHS) that takes account of the expected number of family cases based on the family's age-structure and national cancer incidence rates. Breast cancer risk increased significantly (P trend  history was that combining FHS and age of relative at diagnosis. A family history score based on expected as well as observed breast cancers in a family can give greater risk discrimination on breast cancer incidence than conventional parameters based solely on cases in affected relatives. Our modeling suggests that a yet stronger predictor of risk might be a combination of this score and age at diagnosis in relatives.

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)

Assessment of narghile (shisha, hookah smokers’ actual exposure to toxic chemicals requires further sound studies

Directory of Open Access Journals (Sweden)

2011-05-01

Full Text Available Tobacco smoking is hazardous for health. However, not all forms of tobacco use entail the same risks and the latter should be studied and compared in a sound realistic way. Smoking machines for cigarettes (which are consumed in a few minutes were early designed as a tool to evaluate the actual intake of toxic substances (‘toxicants’ by smokers. However, the yields (tar, nicotine, CO, etc. provided by such machines poorly reflect the actual human smoking behaviour known to depend on numerous factors (anxiety, emotions, anthropological situation, etc.. In the case of narghile smoking, the problems are even more complex, particularly because of the much longer duration of a session. A recent study from the US-American University of Beirut was based on a field smoking topography and claimed consistency with a laboratory smoking machine. We offer a point by point critical analysis of such methods on which most of the ‘waterpipe’ antismoking literature since 2002 is based.

Physics teacher use of the history of science

Science.gov (United States)

Winrich, Charles

The School of Education and the Department of Physics at Boston University offer a sequence of 10 two-credit professional development courses through the Improving the Teaching of Physics (ITOP) project. The ITOP courses combine physics content, readings from the physics education research (PER) literature, and the conceptual history of physics (CHOP). ITOP participants self-report changes to their teaching practices as a result of their participation in ITOP. The purpose of this study was to verify and characterize those changes in the specific area of the participants' use of history after their study of CHOP. Ten recent ITOP participants were observed, interviewed, and asked to provide lesson plans and samples of student work from their classes. Case studies of each participant's teaching were constructed from the data. The individual cases were synthesized to characterize the impact of CHOP on the ITOP participants. The results show that the participants integrate CHOP into their pedagogical content knowledge (PCK) to inform their understanding of: (1) the relationship between physics and other disciplines, (2) the relationship between specific physics concepts, (3) student understanding of physics concepts, (4) student difficulties in learning physics concepts, and (5) methods for teaching physics concepts. The participants use history to teach a variety of topics, although the most common were mechanics and electromagnetism. All of the participants used history to teach aspects of the nature of science (NOS) and to increase student interest in physics, while eight participants taught physics concepts through history. The predominant mode of incorporating history was through adding anecdotes about the scientists who worked on the concepts, but seven participants had their students study the historical development of physical concepts. All the participants discussed a lack of time as a factor that inhibits a greater use of history in their courses. Eight

Reanimating Lost Landscapes: Bringing Visualisation to Aboriginal History

Directory of Open Access Journals (Sweden)

Peter Read

2010-12-01

Full Text Available In Public History Review volume 11, Peter Osborne called for the methodologies of environmental history to be brought more securely and more imaginatively into public history. Environmental history by its own definition, he argued, encompassed Indigenous, ethnic and Anglo-Celtic histories, and heritages natural and built, material and intangible. I believe too that we public historians need to Incorporate changing landscapes and topographies as a vital element in understanding why communities and their built heritages constantly transfigure. Sometimes a single geographic factor such as the northern Gulf Stream can go far to explain the spectacular rise of a small island like Great Britain to world power. Equally we can help to explain the precipitous decline of towns like Bourke by degradation and siltation in the Darling River. This paper uses the case study of the Narrabeen town camp to explore the potential of digital visual technologies in Aboriginal History.

Family cancer history is an important risk factor for common cancers, thus, recognizing pattern of familial cancer can help us to identify individuals who may have higher chance to develop specified cancers. This cross-sectional survey assessed family history of cancer in first- and second degree relatives. Totally, 7,300 persons aged > or = 20 years selected by random sampling from Tehran general population. Age- and sex-specified prevalence of breast and ovarian cancer in respondent's family was calculated. Of all, 279(4.3%) individuals reported a history of breast or ovarian cancer in their relatives. The prevalence of breast cancer family history was 1.8% among first-degree relatives and 2.5% among second- degree relatives. For ovarian cancer, first- and second-degree prevalence ranged from 0.05 to 0.12%. Those with family history of cancer were more often young and female. Overall, the estimates of prevalence presented here are likely to be conservative compared with actual current prevalence because of some limitations. While family history is an important risk factor for common cancers such as breast cancer, recognizing pattern of familial cancer that signify increased risk can help us to identify individuals who may have higher chance to develop specified cancers.

Full Text Available [english] Introduction: Conjunctival melanoma is a relatively rare ocular malignancy with substantial associated morbidity and mortality. It can arise in previously unblemished and unpigmented regions (approximately 10% of cases, from a preexisting nevus (approximately 20% of cases, or from the flat, spreading pigmentation of primary acquired melanosis with atypia (60–70% of cases, actually called conjunctival melanocytic intraepithelial neoplasia (C-MIN with atypia (histopathologically more accurately term. Purpose: The authors describe an extremely rare case of malignant conjunctival melanoma, with a long evolution, in a young black woman. Results: Until now the patient has not shown any sign of relapse of this melanoma, after local excision.Conclusion: Conjunctival melanoma is a condition of concern because of its rarity and lethal potential. Advances in the understanding and management of this neoplasm have markedly reduced the mortality and possibly the morbidity associated with this malignancy. We observe that there are some cases of conjunctival melanoma that might be cured with only a local excision with posterior cryotherapy without more aggressive methods. The practice of narrative medicine brings new possibilities in the diagnosis and collection of classical history.

The Cleanup Standards Committee, formed within the Ohio Federal Facilities Forum, focuses on addressing issues related to cleanup levels and standards. To facilitate decision-making for the disposition of buildings that have potential or actual radiological contamination, the Cleanup Standards Committee developed a process to support building disposition decisions. This process is needed for two reasons: (1) due to changing missions, an increasing number of buildings on federal properties require disposition, and (2) current federal initiatives encourage the transfer of buildings and land for reuse and economic redevelopment. Since the committee developed this process using a teaming effort, the process reflects the experience, expertise, and opinions of committee members and other individuals with a broad range of experience and knowledge. The Generic Process for the Disposition of Buildings that have Potential or Actual Radiological Contamination is intended for use by Federal Facilities responsible for the cleanup of buildings at sites that have radiological process history. This process provides (1) a framework and supporting implementation guidelines for evaluating buildings that have actual or potential radiological contamination, and (2) a process for making building disposition decisions. This paper outlines on the key decision points and the associated data requirements of the process. Specifically, this paper focuses on the following decisions: Which decision-makers are appropriate to involve in the building disposition process; What is the preferred disposition of a building; What criteria are applicable for unconditional release; Is there sufficient existing information to proceed with disposition of a building; What level of survey is appropriate to determine and/or implement a preferred disposition of a building; and how are uncertainties addressed when implementing a building disposition

The incommensurability of psychoanalysis and history.

Science.gov (United States)

Scott, Joan W

2012-01-01

This article argues that, although psychoanalysis and history have different conceptions of time and causality, there can be a productive relationship between them. Psychoanalysis can force historians to question their certainty about facts, narrative, and cause; it introduces disturbing notions about unconscious motivation and the effects of fantasy on the making of history. This was not the case with the movement for psychohistory that began in the 1970s. Then the influence of American ego-psychology on history-writing promoted the idea of compatibility between the two disciplines in ways that undercut the critical possibilities of their interaction. The work of the French historian Michel de Certeau provides theoretical insight into the uses of incommensurability, while that of Lyndal Roper demonstrates both its limits and its value for enriching historical understanding.

Actual heating energy savings in thermally renovated Dutch dwellings

International Nuclear Information System (INIS)

Majcen, Daša; Itard, Laure; Visscher, Henk

2016-01-01

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.

Even if the performance of a given ventilator has been evaluated in the laboratory under very well controlled conditions, inappropriate maintenance and lack of long-term stability and accuracy of the ventilator sensors may lead to ventilation errors in actual clinical practice. The aim of this study was to evaluate the actual performances of ventilators during clinical routines. A resistance (7.69 cmH(2)O/L/s) - elastance (100 mL/cmH(2)O) test lung equipped with pressure, flow, and oxygen concentration sensors was connected to the Y-piece of all the mechanical ventilators available for patients in four intensive care units (ICUs; n = 66). Ventilators were set to volume-controlled ventilation with tidal volume = 600 mL, respiratory rate = 20 breaths/minute, positive end-expiratory pressure (PEEP) = 8 cmH(2)O, and oxygen fraction = 0.5. The signals from the sensors were recorded to compute the ventilation parameters. The average ± standard deviation and range (min-max) of the ventilatory parameters were the following: inspired tidal volume = 607 ± 36 (530-723) mL, expired tidal volume = 608 ± 36 (530-728) mL, peak pressure = 20.8 ± 2.3 (17.2-25.9) cmH(2)O, respiratory rate = 20.09 ± 0.35 (19.5-21.6) breaths/minute, PEEP = 8.43 ± 0.57 (7.26-10.8) cmH(2)O, oxygen fraction = 0.49 ± 0.014 (0.41-0.53). The more error-prone parameters were the ones related to the measure of flow. In several cases, the actual delivered mechanical ventilation was considerably different from the set one, suggesting the need for improving quality control procedures for these machines.

The metabolic changes present in the metabolic syndrome (MetS) have been associated with increased risk of pancreatic and colon cancers; however, there is little information about the association between MetS and cervical cancer risk. We performed a case-control study using data from the National Health and Nutrition Examination Survey (NHANES) between 1999-2010. We identified women 21 years of age and older, of which an estimated 585,924 (2.3% of the sample) self-reported a history of cervical cancer (cases). About half (48.6%) of cases and 33.2% of controls met criteria for MetS. Logistic regression analysis showed increased odds of history of cervical cancer among women with MetS (OR = 1.9; 95% CI 1.06, 3.42; P value ≤ 0.05) for the risk of history of cervical cancer among women with MetS while adjusting for other known risk factors (high number of lifetime sexual partners, multiparty, history of hormonal contraceptive use, and history of smoking) (AOR = 1.82; 95% CI 1.02, 3.26; P value ≤ 0.05). In this US surveyed population we found increased odds of history of cervical cancer among subjects with MetS.

Music as therapy in early history.

Science.gov (United States)

Thaut, Michael H

2015-01-01

The notion of music as therapy is based on ancient cross-cultural beliefs that music can have a "healing" effect on mind and body. Explanations for the therapeutic mechanisms in music have almost always included cultural and social science-based causalities about the uses and functions of music in society. However, it is also important to note that the view of music as "therapy" was also always strongly influenced by the view and understanding of the concepts and causes of disease. Magical/mystical concepts of illness and "rational" medicine probably lived side by side for thousands of years. Not until the late-nineteenth and early-twentieth centuries were the scientific foundations of medicine established, which allowed the foundations of music in therapy to progress from no science to soft science and most recently to actual brain science. Evidence for "early music therapy" will be discussed in four broad historical-cultural divisions: preliterate cultures; early civilizations in Mesopotamia, Egypt, Israel; Greek Antiquity; Middle Ages, Renaissance, and Baroque. In reviewing "early music therapy" practice, from mostly unknown periods of early history (using preliterate cultures as a window) to increasingly better documented times, including preserved notation samples of actual "healing" music, five theories and applications of early music therapy can be differentiated. © 2015 Elsevier B.V.

Meier, Alan; Aragon, Cecilia; Hurwitz, Becky; Mujumdar, Dhawal; Peffer, Therese; Perry, Daniel; Pritoni, Marco

2010-08-15

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.

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.

Case history of controlling a landslide at Panluo open-pit mine in China

Wei, Zuoan; Yin, Guangzhi; Wan, Ling; Shen, Louyan

2008-04-01

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.

Peter Heller's a Child Analysis with Anna Freud: the significance of the case for the history of child psychoanalysis.

Science.gov (United States)

Midgley, Nick

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.

Evaluation of stress histories of reactor coolant loop piping for pipe rupture prediction

International Nuclear Information System (INIS)

Lu, S.C.; Larder, R.A.; Ma, S.M.

1981-01-01

This paper describes the analyses used to evaluate stress histories in the primary coolant loop piping of a selected four-loop PNR power station. In order to make the simulation as realistic as possible, best estimates rather than conservative assumptions were considered throughout. The best estimate solution, however, was aided by a sensitivity study to assess the possible variation of outcomes resulted from uncertainties associated with these assumptions. Sources of stresses considered in the evaluation were pressure, dead weight, thermal expansion, thermal gradients through the pipe wall, residual welding, pump vibrations, and finally seismic excitations. The best estimates of pressure and thermal transient histories arising from plant operations were based on actual plant operation records supplemented by specified plant design conditions. Seismic motions were generated from response spectrum curves developed specifically for the region surrounding the plant site. Stresses due to dead weight and thermal expansion were computed from a three dimensional finite element model which used a combination of pipe, truss, and beam elements to represent the coolant loop piping, the pressure vessel, coolant pumps, steam generators, and the pressurizer. Stresses due to pressure and thermal gradients were obtained by closed form solutions. Seismic stress calculations considered the soil structure interaction, the coupling effect between the containment structure and the reactor coolant system. A time history method was employed for the seismic analysis. Calculations of residual stresses accounted for the actual heat impact, welding speed, weld preparation geometry, and pre- and post-heat treatments. Vibrational stresses due to pump operation were estimated by a dynamic analysis using existing measurements of pump vibrations. (orig./HP)

A modification scheme for seismic acceleration - time histories

International Nuclear Information System (INIS)

Bethell, J.

1979-05-01

A technique is described for the modification of recorded earthquake acceleration-time histories which gives reduced peak accelerations whilst leaving other significant characteristics unchanged. Such modifications are of use in constructing design basis acceleration-time histories such that all important parameters conform to a specified return period. The technique is applied to two recordings from the 1966 Parkfield earthquake, their peak accelerations being reduced in each case from about 40% g to 25% g. (author)

What's Luck Got to Do with It? takes a lively and eye-opening look at the mathematics, history, and psychology of gambling to reveal the most widely held misconceptions about luck. It exposes the hazards of feeling lucky, and uses the mathematics of predictable outcomes to show when our chances of winning are actually good. Mathematician Joseph Mazur traces the history of

Cesium ion exchange using actual waste: Column size considerations

International Nuclear Information System (INIS)

Brooks, K.P.

1996-04-01

It is presently planned to remove cesium from Hanford tank waste supernates and sludge wash solutions using ion exchange. To support the development of a cesium ion exchange process, laboratory experiments produced column breakthrough curves using wastes simulants in 200 mL columns. To verify the validity of the simulant tests, column runs with actual supernatants are being planned. The purpose of these actual waste tests is two-fold. First, the tests will verify that use of the simulant accurately reflects the equilibrium and rate behavior of the resin compared to actual wastes. Batch tests and column tests will be used to compare equilibrium behaviors and rate behaviors, respectively. Second, the tests will assist in clarifying the negative interactions between the actual waste and the ion exchange resin, which cannot be effectively tested with simulant. Such interactions include organic fouling of the resin and salt precipitation in the column. These effects may affect the shape of the column breakthrough curve. The reduction in column size also may change the shape of the curve, making the individual effects even more difficult to sort out. To simplify the evaluation, the changes due to column size must be either understood or eliminated. This report describes the determination of the column size for actual waste testing that best minimizes the effect of scale-down. This evaluation will provide a theoretical basis for the dimensions of the column. Experimental testing is still required before the final decision can be made. This evaluation will be confined to the study of CS-100 and R-F resins with NCAW simulant and to a limited extent DSSF waste simulant. Only the cesium loading phase has been considered

Full Text Available The aim of this study was to know and understand the re-actualization of bale banjar function in Denpasar City. This study was conducted due to the imbalance between the assumptions and current reality. The data sources of this study were some bale banjar-s in Denpasar City, related informants, and previous research findings. All data were collected using observation, interviews, and literature studies techniques and were analyzed using sociocultural evolution, community rationalization, and commodification theories. The research findings showed that re-actualization of bale banjar function in Denpasar City happened due to the high demand of economic space of capitalist economy and the changes of local society’s way of thinking; re-actualization of bale banjar’s form in Denpasar City could be seen from the changes in style and appearance of the spaces that are now widely designed into two floors. The society used the upper floors as a gathering place and the lower floors are rented as a center of economic activity; re-actualization of bale banjar function in Denpasar City had the implications on the way of thinking, the conception of bale banjar form and function and material culture such as the weakening of social relations among krama banjar.

Preservice elementary teachers' actual and designated identities as teachers of science and teachers of students

Science.gov (United States)

Canipe, Martha Murray

stories and enactments in order to determine which storytellers were significant narrators for the preservice teachers' identities. The findings from this study show that significant narrators vary among the preservice teachers and include artifacts such as curriculum materials and instructional models in addition to people who are expected to be significant narrators. Furthermore, differences between preservice teachers' actual and designated identities influence opportunities to learn about what it means to be a teacher of science and students. This took different forms with each preservice teacher. In one case the preservice teacher worked to enact aspects of her designated identity and reflected about how she was not quite able to be the teacher of science she wanted to be as a novice teacher. Another case showed how the gap between actual and designated identities could limit opportunities to learn when the preservice teacher's strong actual identity as a novice led her to consider certain aspects of her designated identity as things which could not even be tried at this point. Finally, in the third case the preservice teacher's strong actual identity limited opportunities to develop a designated identity because she did not see herself as being a different kind of teacher of science in the future than she was right now as a student teacher. These findings suggest that supporting preservice elementary teacher identity development as teachers of science is an important part of preparing them to teach science in ways that engage students in scientific practices. Additionally, it is essential to examine identity stories and enactments in concert with each other in order to gain deeper understandings of how identities are developed and put into practice in classrooms.

Narrative and natural history in the eighteenth century.

Science.gov (United States)

Terrall, Mary

2017-04-01

In the eighteenth century, natural histories of animals incorporated narratives about animal behaviour and narratives of discovery and experimentation. Naturalists used first-person accounts to link the stories of their scientific investigations to the stories of the animal lives they were studying. Understanding nature depended on narratives that shifted back and forth in any given text between animal and human, and between individual cases and generalizations about species. This paper explores the uses of narrative through examples from the work of René-Antoine Ferchault de Réaumur and Abraham Trembley. In all cases, narrative took the genre of natural history well beyond straightforward description and classification. Prose accounts of insect actions and mechanisms worked in tandem with visual narratives embedded in the accompanying illustrations, where artists developed strategies for representing sequences of minute changes over time. By throwing into relief the narrative sections of natural histories, the examples considered here expose the role played by these tales of encounters with the insect world in the making of natural historical knowledge.

Mental chronometry, commonly used to evaluate motor imagery ability, measures the imagined time required for movements. Previous studies investigating mental chronometry of walking have investigated healthy older adults. However, mental chronometry in frail older adults has not yet been clarified. To investigate temporal characteristics of imagined and actual walking in frail older adults. We investigated the time required for imagined and actual walking along three walkways of different widths [width(s): 50, 25, 15 cm × length: 5 m] in 29 frail older adults and 20 young adults. Imagined walking was measured with mental chronometry. We observed significantly longer imagined and actual walking times along walkways of 50, 25, and 15 cm width in frail older adults compared with young adults. Moreover, temporal differences (absolute error) between imagined and actual walking were significantly greater in frail older adults than in young adults along walkways with a width of 25 and 15 cm. Furthermore, we observed significant differences in temporal differences (constant error) between frail older adults and young adults for walkways with a width of 25 and 15 cm. Frail older adults tended to underestimate actual walking time in imagined walking trials. Our results suggest that walkways of different widths may be a useful tool to evaluate age-related changes in imagined and actual walking in frail older adults.

Full Text Available Foreign bodies in the knee joint are not uncommon. We report a case of sewing needle that migrated and embedded inside the knee with no history of trauma. Searching for any small foreign body in the knee joint is not easy in either open or arthroscopic procedures. In this case, the surgery was made by open method avoiding arthroscopy due to technical reasons. We emphasize careful history taking, clinical examination and, preferably, an open procedure for migrating tiny foreign bodies to facilitate accurate diagnosis, superior visualization and easier instrumentation to remove embedded foreign bodies in the knee.

Duncan, Michael J; Jones, Victoria; O'Brien, Wesley; Barnett, Lisa M; Eyre, Emma L J

2018-04-01

Children's perception of their own motor competence is an important correlate of their actual motor competence. The current study is the first to examine this association in British children and the first to use both product and process measures of actual motor competence. A total of 258 children (139 boys and 119 girls; aged 4 to 7 years, Mean = 5.6, SD = .96) completed measures of self-perceived motor competence using the Pictorial Scale for Perceived Movement Competence in Young Children. Children were classified as "Low," "Medium," or "High" perceived competence based on tertile analysis. Actual motor competence was assessed with the Test of Gross Motor Development-2 (a process measure) and a composite of 10-m sprint run time, standing long jump distance, and 1-kg seated medicine ball throw (collectively, a product measure). Data for process and product measures were analyzed using a 2 (sex) × 3 (high, medium, low perceived competence) analysis of covariance, with body mass index, calculated from height and mass, and age controlled. Boys obtained significantly higher scores than girls for both the process ( p = .044) and product ( p = .001) measures of actual motor competence. Boys had significantly ( p = .04) higher scores for perceived competence compared to girls. Compared to children classified as medium and high self-perceived competence, children classified as low self-perceived competence had lower process ( p = .001) and product scores (i.e., medium, p = .009 and high, p = .0001) of actual motor competence. Age ( p = .0001) and body mass index ( p = .0001) were significantly associated with product motor competence. Strategies to enhance actual motor competence may benefit children's self-perceived motor competence.

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.

Nurses without borders: the history of nursing as U.S. international history.

Science.gov (United States)

Irwin, Julia F

2011-01-01

During World War I and its aftermath, thousands of U.S. nurses put their domestic careers on hold to work overseas. Many volunteered in the wake of war and disaster. Others worked as instructors in nursing schools and as the staff of fledgling public health agencies. This article charts the international travels of four especially mobile nurses, whose globetrotting careers took them to Europe, Asia, and the Caribbean. These women aspired to tackle world health issues, motivated by the conviction that the spread of U.S. professional nursing ideas stood to modernize the world. This article tells these nurses' stories and analyzes their ideologies of development and progress. In so doing, it demonstrates that professional women, working outside state channels, played a principal role in expanding U.S. influence in the world. Moreover, it makes the case for the centrality of nursing history to the history of U.S. foreign relations.

Precarious employment, ill health, and lessons from history: the case of casual (temporary) dockworkers 1880-1945.

Science.gov (United States)

Quinlan, Michael

2013-01-01

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.

[Assessment of actual benefits of new drugs by the Transparency Committee].

Science.gov (United States)

Le Jeunne, C

2008-01-01

When a drug has been granted a marketing authorization, if the pharmaceutical company wants it to be covered by the National Health Insurance, the company has to submit a file with all the studies concerning the drug, especially drug-drug comparative studies, to be assessed by the Transparency Committee. Drugs are assessed on two criteria: actual or expected benefit (AB) and improvement in actual benefit (IAB). Actual benefit mainly takes into account the severity of the disease concerned, the level of efficacy relative to known side effects (risk-benefit ratio), and the place the drug is intended to take in the therapeutic strategy. At the end of the assessment, AB is considered as important, moderate, poor or insufficient (to justify inclusion of the drug on the list of products to be reimbursed). After actual benefit is determined, improvement of actual benefit is assessed, comparing the estimated benefit of this drug with one of drugs with the same indication that is already reimbursed, to assess whether this drug will improve the patient's disease. This can be assessed by direct comparison (two drugs compared in the same clinical trial) or by indirect comparison (separate studies with the same design). There are four levels of added value, from I (major improvement) to IV (minor improvement). Level V represents no improvement. This second assessment is always relative to another drug. It never provides an absolute score. However, IAB is very important for pharmaceutical companies, because it is a fundamental criterion to determine the price of the drug, which is discussed with the Economic Committee of Health Products in a final phase. Actual benefit and improvement in actual benefit are allocated for each indication of a drug.

A Categorization Model for Educational Values of the History of Mathematics. An Empirical Study

Wang, Xiao-qin; Qi, Chun-yan; Wang, Ke

2017-11-01

There is not a clear consensus on the categorization framework of the educational values of the history of mathematics. By analyzing 20 Chinese teaching cases on integrating the history of mathematics into mathematics teaching based on the relevant literature, this study examined a new categorization framework of the educational values of the history of mathematics by combining the objectives of high school mathematics curriculum in China. This framework includes six dimensions: the harmony of knowledge, the beauty of ideas or methods, the pleasure of inquiries, the improvement of capabilities, the charm of cultures, and the availability of moral education. The results show that this framework better explained the all-educational values of the history of mathematics that all teaching cases showed. Therefore, the framework can guide teachers to better integrate the history of mathematics into teaching.

To implement and evaluate the use of a situated-learning experience to prepare second-year pharmacy students to conduct medication history interviews in preparation for introductory pharmacy practice experiences (IPPE) at ambulatory clinic sites. Second-year doctor of pharmacy (PharmD) students (n=200) used the Medication Mysteries Infinite Case Tool, a game-like educational tool in which groups of 3 students assumed the roles of pharmacist, patient, and observer and rolled a die and drew cards to determine the drugs, patient personality, medication problems, and other variables that guided a medication history taking session. After the laboratory session, faculty members assessed students' medication history-taking skills. One hundred sixteen (58%) and 78 (39%) of 200 students achieved excellence or competence, respectively, on the final assessment. Two weeks after the assessment, 53 of 200 (26.5%) students completed a survey instrument. The respondents indicated that their self-confidence in conducting medical history taking significantly improved following completion of the learning experience. Using the Medication Mysteries Infinite Case Tool increased students' confidence and skills in conducting medication history taking prior to their clinical IPPE experience.

SELF-REALIZATION IS INSEPARABLE FROM SELF-ACTUALIZATION OF A PERSONALITY

Irina Ivanovna Vitkovskaya

2016-02-01

Full Text Available The article considers the issues of a personality’s self-realization and self-actualization under current educational standards required in the time of impetuous development in informative technologies. The practical aspect of the article describes self-realization and self-actualization of a person as their social and useful activity, interdiscipline approach, it is characterised by interdependence of an individual and their social environment apart with the self-realization of a personality in educational process. Evidently, being a substantial ca-tegory of vital «self-assertion», it should be thought over in categories of self-actualization and self-realization. So, self-realization is considered to be a social process which continues all conscientious life. In pedagogics of our country, labour and professional activity were the spheres of self-actualization therefore, it should be taken into account external factors for self-realization and self-actualization of a person. If socio-pedagogic conditions presuppose having good teachers, what conditions should be created in an individual’s micro-groups and in particular, in the family and kind of values shoud an individual get through the process of socialization. Thus, technological project of self-realization of a personality has to assume that there is the strive for self-perfection and interrelation of ways of self-realization, self-education, and adaptation. The correlation of these ways in a specific educational field is the purpose of the article.

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.

We report a case of sirenomelia sequence observed in an incident of preterm labor during the 29th gestational week. According to some authors, this syndrome should be classified separately from caudal regression syndrome and is likely to be the result of an abnormality taking place during the fourth gestational week, causing developmental abnormalities in the lower extremities, pelvis, genitalia, urinary tract and digestive organs. Despite recent progress in pathology, the etiopathogenesis of sirenomelia is still debated. PMID:21769253

2006-01-01

Full Text Available The present studies address two criticisms of the theory of evolved sex differences in jealousy: (a that the sex difference in jealousy emerges only in response to hypothetical infidelity scenarios, and (b that the sex difference emerges only using forced-choice measures. In two separate studies, one a paper-and-pencil survey with a student sample and the other a web-based survey targeting a non-student sample, men and women showed significant sex differences in jealousy in response to actual infidelity experiences; men experienced more jealousy in response to the sexual aspects of an actual infidelity, whereas women experienced more jealousy in response to the emotional aspects of the infidelity. Sex differences emerged using both continuous measures of jealousy as well as the traditional forced-choice measure. Overall, our results demonstrate that sex differences in jealousy are not limited to responses to hypothetical infidelity scenarios; they also emerge in response to actual infidelity experiences.

History of 232-F, tritium extraction processing

International Nuclear Information System (INIS)

Blackburn, G.W.

1994-08-01

In 1950 the Atomic Energy Commission authorized the Savannah River Project principally for the production of tritium and plutonium-239 for use in thermonuclear weapons. 232-F was built as an interim facility in 1953--1954, at a cost of $3.9M. Tritium extraction operations began in October, 1955, after the reactor and separations startups. In July, 1957 a larger tritium facility began operation in 232-H. In 1958 the capacity of 232-H was doubled. Also, in 1957 a new task was assigned to Savannah River, the loading of tritium into reservoirs that would be actual components of thermonuclear weapons. This report describes the history of 232-F, the process for tritium extraction, and the lessons learned over the years that were eventually incorporated into the new Replacement Tritium Facility

Several studies have shown that actual thermal performance of buildings after construction may deviate significantly from that anticipated at design stage. As a result, there is growing interest in full scale testing of components and whole buildings. The IEA EBC Annex 58-project ‘Reliable Building...... Energy Performance Characterisation Based on Full Scale Dynamic Measurements’ is developing the necessary knowledge and tools to achieve reliable in-situ dynamic testing and data analysis methods that can be used to characterise the actual thermal performance and energy efficiency of building components...... and whole buildings. The research within this project is driven by case studies. As a first simple case, an experiment on testing and data analysis is performed on a round robin test box. This test box can be seen as a scale model of a building, built by one of the participants, with fabric properties...

The meaning and message of the history of science will be discussed with relevance to XX century physics. This decisive period began in 1894-95 with the discoveries of the electron,X-rays and radioactivity,with the consequent development of relativity and quantumphysics. Connections of the development of science and society in XX century with culture and the influence on industry will be examined. Finally, the corruption of physics by the military will be considered. The influence of physics on chemistry and biology will be briefly treated and the impact of the approach and method of physics on modern thinking will be assessed. It should be kept in mind that the history of science is not a way of getting a simplified or adulterated presentation of the subject ,in this case of physics and so some understanding of general physics will be assumed. On the other hand, the broader generalisations of the history of ideas and events are illustrated (if not proven) by the facts (and myths) of science. Finally,as an e...

Correlation between familial cancer history and epidermal growth factor receptor mutations in Taiwanese never smokers with non-small cell lung cancer: a case-control study.

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.

Contributions to the Chile’s Seismic History: the Case of the Great Earthquake of 1730

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.

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.

Understanding the natural history of Gaucher disease.

Mistry, Pramod K; Belmatoug, Nadia; vom Dahl, Stephan; Giugliani, Roberto

2015-07-01

Gaucher disease is a rare and extraordinarily heterogeneous inborn error of metabolism that exhibits diverse manifestations, a broad range of age of onset of symptoms, and a wide clinical spectrum of disease severity, from lethal disease during infancy to first age of onset of symptoms in octogenarians. Before the advent of the International Collaborative Gaucher Group (ICGG) Gaucher Registry, the understanding of the natural history and phenotypic range of Gaucher disease was based on isolated case reports and small case series. Limited data hindered understanding of the full spectrum of the disease leading to some early misconceptions about Gaucher disease, notably, that nonneuronopathic (type 1) disease was a disease of adults only. The global scope of the ICGG Gaucher Registry, with its vast body of longitudinal data, has enabled a real appreciation of both the phenotypic spectrum of Gaucher disease and its natural history. This body of evidence represents the foundation for accurate assessment of the response to specific therapies for Gaucher disease and to the development of standard-of-care to monitor disease activity. Here, we outline the key developments in delineating the natural history of this highly complex disease and role of the ICGG Gaucher Registry in this effort. © 2015 Wiley Periodicals, Inc.

SHARI’A, INDIGENOUS WISDOM AND HUMAN RIGHTS: A Brief Review of Human Rights Enforcement in the Context of Indonesian History

Directory of Open Access Journals (Sweden)

JM. Muslimin

2015-12-01

Full Text Available This article deals with the analysis of how human rights discourses have been articulated in the landscape of Indonesia’s history. The paper argues that the idea of Shari’aization can undermine the search for the common ground in building the discourses of human rights. The history of Indonesia can be classified into three eras: pre-colonial, post-colonial and reform era. Along the history, the spirit of human rights enforcement grows from, and interacts with, Islam and local culture. The language and expression take various forms in accordance with socio-cultural contexts and challenges. However, the essence of the enforcement is rooted in the universal values: freedom from oppression, fear, discrimination and gender inequality. In the future, smart dialogue, sharp debate and sincere discussion between ‘local’ symbolic expression and universal standardization are still needed. In addition, the gap can be narrowed also by responding actual violation of human right as it is indicated by Indonesian history: history of social consensus.

The widespread use of endosseous osseointegrated implants to replace missing natural teeth increases the chances of implant complications and failures, despite the high initial success rate reported in the literature. Implant fracture is one possible complication that results in ultimate failure of the dental implant. Such a complication poses a management crisis even for the most experienced clinician. This article reports on a case of implant fracture, its possible causes, and how the case was managed.

Purpose: The purpose of this study was to determine the prevalence of a history of ocular trauma and its association to age, sex, and biometric components. Materials and Methods: Residents of Shahroud, Iran aged 40–64 years, were sampled through a cross-sectional study using multistage cluster sampling. Three hundred clusters were randomly selected, and 20 individuals were systematically selected from each cluster. The subjects underwent optometric and ophthalmic examinations, and ocular imaging. A history of ocular trauma was determined through personal interviews. Results: The prevalence of a history of trauma and blunt trauma, sharp trauma, and chemical burns were 8.57%, 3.91%, 3.82%, and 1.93%, respectively. After adjusting for age, the rate of all types of trauma was significantly higher for males. Only the prevalence of chemical burns significantly decreased with aging. A history of hospitalization was stated by 1.64% of the subjects. The axial length was significantly longer in cases with a history of trauma. The corneal curvature was significantly larger in cases with a history of sharp trauma and chemical burns. The prevalence of corneal opacities was significantly higher among cases with a history of the blunt trauma odds ratio (OR = 2.33) and sharp trauma (OR = 4.46). Based on corrected visual acuity, the odds of blindness was 3.32 times higher in those with a history of ocular trauma (P < 0.001). Conclusion: A considerable proportion of the 40–64-year-old population reported a history of ocular trauma. This observation has important health implications. Blindness, corneal opacities, and posterior subcapsular cataract were observed more frequently among these cases, and they demonstrated differences in some ocular biometric components. PMID:26180480

The actual citation impact of European oncological research.

This study provides an overview of the research performance of major European countries in the field Oncology, the most important journals in which they published their research articles, and the most important academic institutions publishing them. The analysis was based on Thomson Scientific's Web of Science (WoS) and calculated bibliometric indicators of publication activity and actual citation impact. Studying the time period 2000-2006, it gives an update of earlier studies, but at the same time it expands their methodologies, using a broader definition of the field, calculating indicators of actual citation impact, and analysing new and policy relevant aspects. Findings suggest that the emergence of Asian countries in the field Oncology has displaced European articles more strongly than articles from the USA; that oncologists who have published their articles in important, more general journals or in journals covering other specialties, rather than in their own specialist journals, have generated a relatively high actual citation impact; and that universities from Germany, and--to a lesser extent--those from Italy, the Netherlands, UK, and Sweden, dominate a ranking of European universities based on number of articles in oncology. The outcomes illustrate that different bibliometric methodologies may lead to different outcomes, and that outcomes should be interpreted with care.

 Recent studies suggest that differences in biological characteristics and risk factors across cancer site within the colon and rectum may translate to differences in survival. It can be challenging at times to determine the precise anatomical location of a lesion with a luminal view during colonoscopy. The aim of this study is to determine if there is a significant difference between the location of colorectal cancers described by gastroenterologists in colonoscopies and the actual anatomical location noted on operative and pathology reports after colon surgery.  A single-center retrospective analysis of colonoscopies of patient with reported colonic masses from January 2005 to April 2014 (n = 380) was carried. Assessed data included demography, operative and pathology reports. Findings were compared: between the location of colorectal cancers described by gastroenterologists in colonoscopies and the actual anatomical location noted on operative reports or pathology samples.  We identified 380 colonic masses, 158 were confirmed adenocarcinomas. Of these 123 underwent surgical resection, 27 had to be excluded since no specific location was reported on their operative or pathology report. An absolute difference between endoscopic and surgical location was found in 32 cases (33 %). Of these, 22 (23 %) differed by 1 colonic segment, 8 (8 %) differed by 2 colonic segments and 2 (2 %) differed by 3 colonic segments.  There is a significant difference between the location of colorectal cancers reported by gastroenterologists during endoscopy and the actual anatomical location noted on operative or pathology reports after colon surgery. Endoscopic tattooing should be used when faced with any luminal lesions of interest.

Is the Einstein de Sitter model actually ruled out?

The standard model for cosmology which is now strongly favored is a flat model, dominated by a vacuum density term. However, the actual direct evidences for such term are limited, essentially based on the supernova probe, i.e. based on a standard candle hypothesis. Here I would like to point out that contrary to the general belief there is room for an Einstein de Sitter universe. Actually several independent measurements, not based on stellar reference, pointed towards a high matter density Universe, weakening the need for a cosmological constant

Medications are perceived as health risk factors, because they might cause damage if used improperly. In this context, an adequate assessment of medication use history should be encouraged, especially in transitions of care to avoid unintended medication discrepancies (UMDs). In a case-controlled study, we investigated potential risk factors for UMDs at hospital admission and found that 150 (42%) of the 358 patients evaluated had one or more UMDs. We were surprised to find that there was no record of a patient and/or relative interview on previous use of medication in 117 medical charts of adult patients (44.8%). Similarly, in the medical charts of 52 (53.6%) paediatric patients, there was no record of parents and/or relatives interviews about prior use of medications. One hundred thirty-seven medical charts of adult patients (52.4%) and seventy-two medical charts of paediatric patients (74.2%) had no record about medication allergies and intolerances. In other words, there was a lack of basic documentation regarding the patient's medication use history. As patients move between settings in care, there is insufficient tracking of verbal and written information related to medication changes, which results in a progressive and cumulative loss of information, as evidenced by problems associated with clinical transfers and medication orders. Proper documentation of medication information during transfer is a key step in the procedure; hence, it should be rightly performed. It remains unclear whether interviews, and other investigations about medication use history have been performed but have not been recorded as health-care data. Therefore, it is crucial to the improvement of medication use safety that documentation of all drug-related information-even if not directly related to the actual event-become routine practice in health-care organizations, since 'what is not written does not exist'.

A key part in unraveling the history of the physical evolution of the earth is knowledge of the earth's thermal history. 40 Ar/ 39 Ar step heating of mineral samples provides a means of defining a local thermal history. to do this accurately the challenge is to extract meaningful diffusion parameters from a mineral's Arrhenius plot. In the case of biotite single grains, where the laboratory release of argon is a complex process, this can be a difficult task. (12 refs., 5 figs.)

The Norwegian curriculum in history and historical thinking: a case study of three lower secondary schools

Directory of Open Access Journals (Sweden)

Lisbeth Bergum Johanson

2015-03-01

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. To accomplish historical understanding it is suggested that both teachers and students

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.

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.

2015-04-01

The association between Barrett's esophagus (BE) and a personal or family history of cancer other than gastroesophageal remains unknown. To evaluate the effect of personal and family history of certain cancers and cancer treatments on the risk of BE, we analyzed data from a Veterans Affairs case-control study that included 264 men with definitive BE (cases) and 1486 men without BE (controls). Patients with history of esophageal or gastric cancer were excluded. Patients underwent elective esophagogastroduodenoscopy or a study esophagogastroduodenoscopy concurrently with screening colonoscopy to determine BE status. Personal and family history of several types of cancer was obtained from self-reported questionnaires, supplemented and verified by electronic medical-record reviews. We estimated the association between personal and family history of cancer or radiation/chemotherapy, and BE. Personal history of oropharyngeal cancer (1.5% vs. 0.4%) or prostate cancer (7.2% vs. 4.4%) was more frequently present in cases than controls. The association between BE and prostate cancer persisted in multivariable analyses (adjusted odds ratio 1.90; 95% confidence interval 1.07-3.38, P = 0.028) while that with oropharyngeal cancer (adjusted odds ratio 3.63; 95% confidence interval 0.92-14.29, P = 0.066) was attenuated after adjusting for retained covariates of age, race, gastroesophageal reflux disease, hiatal hernia, and proton pump inhibitor use. Within the subset of patients with cancer, prior treatment with radiation or chemotherapy was not associated with BE. There were no significant differences between cases and controls in the proportions of subjects with several specific malignancies in first- or second-degree relatives. In conclusion, the risk of BE in men may be elevated with prior personal history of oropharyngeal or prostate cancer. However, prior cancer treatments and family history of cancer were not associated with increased risk of BE. Further studies are needed

Seismic qualification by test is widely used as a way to show the integrity and functionality of equipment that is related to the overall safety of nuclear power plants. Another means of seismic qualification is by direct integration analysis. Both approaches require a series of time histories as an input. However, in most cases, the possibility of using real earthquake data is limited. Thus, artificial time histories are widely used instead. In many cases, however, response spectra are given. Thus, most of the artificial time histories are generated from the given response spectra. Obtaining the response spectrum from a given time history is straightforward. However, the procedure for generating artificial time histories from a given response spectrum is difficult and complex to understand. Thus, this paper presents a simple time-domain method for generating a time history from a given response spectrum; the method was shown to satisfy conditions derived from nuclear regulatory guidance.

Hypothyroidism in a five-year-old boy with rhabdomyolysis and recent history of cardiac tamponade: a case report

Directory of Open Access Journals (Sweden)

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.

Evaluation of significance of positive familial history in prevalence of hypertension in Isfahan

1997-09-01

Full Text Available Hypertension is one of the most important modifiable risk factors of vascular heart disease. Control of hypertension in different age groups has a significant effect upon the control and prevention of vascular heart disease. A familial pattern is observed in the distribution of blood pressure in different societies. Family history of hypertension has a profound effect on the future risk of developing hypertension. The blood pressure of approximately 8150 inhabitants of Isfahan aged above 18 years was measured during 1993-94. Blood pressure measurements were performed according to the standards set by WHO i.e., on two separate occasions, in the sitting position, and from both arms. A questionnaire was completed consisting of 26 questions, including questions regarding history of hypertension in first and second-degree relatives. Cases with a blood pressure of 140/90 mmHg or more, were referred to the Cardiovascular Research Center of Isfahan for further evaluation. Mean systolic and diastolic blood pressure was higher in cases with a positive family history of hypertension. In this study, 37.4% of the men with hypertension and 45.4% of hypertensive women had positive history of hypertension in first-degree relatives. The association between positive family history and hypertension was not significant in men (P=0.62, but it was significant in women (P=0.000. This difference was less pronounced in the older age groups, which could be explained by the illiteracy of most of the older cases and their ignorance of the existence of hypertension in family members. After correcting for the effects of confounding factors, it appears that positive family history has a stronger association with the development of hypertension in women. Moreover, positive family history is a strong prognostic factor in the likelihood of hypertension in the children of affected cases. These findings emphasize the importance of routine blood pressure measurement in children and

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

Case histories of microbiologically influenced corrosion of austenitic stainless steel weldments

Borenstein, S.W.; Buchanan, R.A.; Dowling, N.J.E.

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

Although great strides have been made in increasing equality and inclusion in organizations, a number of stigmatized groups are overlooked by diversity initiatives, including people with a history of cancer. To examine the workplace experiences of these individuals in selection contexts, we conducted 3 complementary studies that assess the extent to which cancer is disclosed, the stereotypes associated with cancer in the workplace, and discrimination resulting from these stereotypes. In a pilot study, we surveyed 196 individuals with a history of cancer (across 2 samples) about their workplace disclosure habits. In Study 1, we explored stereotypes related to employees with a history of cancer using the framework outlined by the stereotype content model. In Study 2, we used a field study to assess the experiences of job applicants who indicated they were "cancer survivors" (vs. not) with both formal and interpersonal forms of discrimination. This research shows that cancer is disclosed at relatively high rates (pilot study), those with a history of cancer are stereotyped as being higher in warmth than competence (Study 1), and the stereotypes associated with those who have had cancer result in actual discrimination toward them (Study 2). We discuss the theory behind these findings and aim to inform both science and practice with respect to this growing workplace population. (c) 2016 APA, all rights reserved).

Cosmic growth history and expansion history

Linder, Eric V.

2005-01-01

The cosmic expansion history tests the dynamics of the global evolution of the universe and its energy density contents, while the cosmic growth history tests the evolution of the inhomogeneous part of the energy density. Precision comparison of the two histories can distinguish the nature of the physics responsible for the accelerating cosmic expansion: an additional smooth component--dark energy--or a modification of the gravitational field equations. With the aid of a new fitting formula for linear perturbation growth accurate to 0.05%-0.2%, we separate out the growth dependence on the expansion history and introduce a new growth index parameter γ that quantifies the gravitational modification

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.

In this study, the author uses Dramaturgy Theory introduced by Erving Goffman 1955 in The Presentation of Self in Everyday Life.                This research methods using qualitative methodology and data collection technique was done by observation, interviews and  study by literature. Trends goes to coffee shop by teen nowdays be assumed as teen’s activity to follow modern life style and it does to complete needs of self actualization.             It was concluded that the phenomenon of teenage habit to go to the coffee shop is an adolescent self-actualization behaviors performed by following a growing trend. Dramaturgy Theory discusses the two sides of teenage life in self actualize, front stage of a teenager is a person who has wide connections and likes to follow the trend of going to the coffee shop, and the back stage of the teenager is the pupil / student in an educational institution and a child in a family whose primary job is to learn and serve the elderly.

Antibody titers against EBNA1 and EBNA2 in relation to Hodgkin lymphoma and history of infectious mononucleosis

Mueller, Nancy E.; Lennette, Evelyne T.; Dupnik, Kathryn; Birmann, Brenda M.

2013-01-01

A role for Epstein Barr virus (EBV) in Hodgkin lymphoma (HL) pathogenesis is supported by the detection of EBV genome in about one-third of HL cases, but is not well defined. We previously reported that an elevated pre-diagnosis antibody titer against EBV nuclear antigens (EBNA) was the strongest serologic predictor of subsequent HL. For the present analysis, we measured antibody levels against EBNA components EBNA1 and EBNA2 and computed their titer ratio (anti-EBNA1:2) in serum samples from HL cases and healthy siblings. We undertook this analysis to examine whether titer patterns atypical of well-resolved EBV infection, such as an anti-EBNA1:2 ratio ≤1.0, simply reflect history of infectious mononucleosis (IM), an HL risk factor, or independently predict HL risk. Participants were selected from a previous population-based case-control study according to their history of IM. We identified 55 EBV-seropositive persons with a history of IM (IM+; 33 HL cases, 22 siblings) and frequency-matched a comparison series of 173 IM history-negative, EBV-seropositive subjects on HL status, gender, age, and year of blood draw (IM−; 105 cases, 58 siblings). In multivariate logistic regression models, an anti-EBNA1:2 ratio ≤1.0 was significantly more prevalent in HL cases than siblings (odds ratio, 95% confidence interval=2.43, 1.05–5.65); similar associations were apparent within the IM+ and IM− groups. EBNA antibodies were not significantly associated with IM history in HL cases or siblings. These associations suggest that chronic or more severe EBV infection is a risk factor for HL, independent of IM history. PMID:21805472

The status of American competitiveness in high technology, and in particular the semiconductor industry, has been the subject of concern for some time now.1 With the rise of Japanese manufactures to preeminence in the manufacturing of DRAM (Dynamic Random Access Memory) chips during the 1980's, the fundamental assumptions of modern economic theory have been called into question.2 Various factors have been cited by various authors to account for the recent rise in Japanese competitiveness, including industrial policies of the Japanese government, differences in the cost of capital, investments in research and development, and the requirement of American companies to post financial results quarterly.3 There is, however, a real need for concrete case studies, which can examine the actual history of a technology and establish mechanisms of cause and effect.

How to study the history of European law?

DEFF Research Database (Denmark)

Rasmussen, Morten

This paper has a double purpose. On the one hand, it offers a new history, based on recently discovered primary sources, of the driving forces behind the so-called ‘constitutionalisation’ of European law taking place in 1963-64. On the other hand, it uses the lessons of this new history to reflect...... on how a general history of European law should be written and in particular how to avoid the pitfalls that characterises mainstream research on European law. In the first part it is argued that the ‘constitutionalisation’ of European law was promoted by a broad coalition beyond the Court of Justice...... the ‘constitutionalisation’ of European law in the 1960s. This is in particular the case with the ‘integration-through-law’ paradigm that permeates most of the writing on European law even today. Concluding, it is argued that a general history of European law should avoid the adoption of mainstream conceptualisations...

A case of exemplarity: C. F. Rottböll's history of smallpox inoculation in Denmark-Norway, 1766.

Science.gov (United States)

Eriksen, Anne

2010-01-01

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.

Bringing dinosaurs back to life: exhibiting prehistory at the American Museum of Natural History.

Science.gov (United States)

Rieppel, Lukas

2012-09-01

This essay examines the exhibition of dinosaurs at the American Museum of Natural History during the first two decades of the twentieth century. Dinosaurs provide an especially illuminating lens through which to view the history of museum display practices for two reasons: they made for remarkably spectacular exhibits; and they rested on contested theories about the anatomy, life history, and behavior of long-extinct animals to which curators had no direct observational access. The American Museum sought to capitalize on the popularity of dinosaurs while mitigating the risks of mounting an overtly speculative display by fashioning them into a kind of mixed-media installation made of several elements, including fossilized bone, shellac, iron, and plaster. The resulting sculptures provided visitors with a vivid and lifelike imaginative experience. At the same time, curators, who were anxious to downplay the speculative nature of mounted dinosaurs, drew systematic attention to the material connection that tied individual pieces of fossilized bone to the actual past. Freestanding dinosaurs can therefore be read to have functioned as iconic sculptures that self-consciously advertised their indexical content.

Historia and materia: the philosophical implications of Francis Bacon's natural history.

Science.gov (United States)

Giglioni, Guido

2012-01-01

This article examines the philosophical implications underlying Bacon's views on historical knowledge, paying special attention to that variety of historical knowledge described by Bacon as "natural." More specifically, this article explores the interplay of history (historia) and fable (fabula). In the sphere of thought, fabula is the equivalent to materia in nature. Both are described by Bacon as being "versatile" and "pliant." In Bacon's system of knowledge, philosophy, as the domain of reason, starts from historiae and fabulae, once memory and the imagination have fulfilled their cognitive tasks. This means that, for Bacon, there is no such thing as a pure use of reason. He advocates a kind of reason that, precisely because it is involved with matter's inner motions (its "appetites," in Bacon's characteristic language), is constitutively 'impure'. The article shows how the terms historia and fabula cover key semantic areas in defining Bacon's philosophy: historia may mean "history" as well as "story,"fabula "myth" as well "story". In both cases, we can see significant oscillations from a stronger meaning (close to those of matter and nature) to a weaker one (connected to wit and imagination), as if the power of nature decreases moving from histories and myths to stories. On the other hand, there are cases in which Bacon seems to stick to a diachronic view of the meaning of fables and histories, such that the transition from myths to history, especially natural history, is described as a collective effort towards reality and enlightenment.

Astasia-Abasia and Ganser syndrome in a preadolescent girl: A case report

Directory of Open Access Journals (Sweden)

2015-01-01

Full Text Available Introduction. Astasia is the inability to maintain an upright body position without assistance in the absence of motor weakness or sensory loss. Abasia is described as the inability to walk or as uncoordinated walking, while preserving mobility of the lower limbs. Ganser syndrome is described as a dissociative disorder characterized by approximate answers, somatic conversion symptoms, clouding of consciousness, as well as visual and auditory pseudohallucinations. The aim of this study is to present a case that seemed like a combination of neurological and internal disturbances, but actually represented a psychogenic disorder. Case Outline. This paper presents the case of a 13-year-old patient with the first manifestation of the inability to walk and stand. Medical history, diagnostic instruments and differential diagnostic methods have been presented in detail. The clinical manifestation was initially interpreted as a neurological disorder. However, after the application of diagnostic procedures and a change in family circumstances, the patient was diagnosed with a psychogenic movement disorder, astasia-abasia, with progressive clinical presentation that included dissociative psychotic reactions (Ganser syndrome. Differential diagnosis as well as the elements of the therapeutic approach have been discussed. Conclusion. Presenting a case of psychogenic astasia-abasia in children contributes to a better understanding and differentiating between conditions with a clinical presentation of signs and symptoms dealt with by other branches of medicine.

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.

History writing and state legitimisation in postcolonial Mozambique: the case of the History Workshop, Centre for African Studies, 1980-1986

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

Yun, Hyong Geun; Lee, Hyun Koo

1995-01-01

Purpose : Authors tried to enhance the safety and accuracy of radiosurgery by verifying stereotactic target point in actual treatment position prior to irradiation. Materials and Methods : Before the actual treatment, several sections of anthropomorphic head phantom were used to create a condition of unknown coordinated of the target point. A film was sand witched between the phantom sections and punctured by sharp needle tip. The tip of the needle represented the target point. The head phantom was fixed to the stereotactic ring and CT scan was done with CT localizer attached to the ring. After the CT scanning, the stereotactic coordinates of the target point were determined. The head phantom was secured to accelerator's treatment couch and the movement of laser isocenter to the stereotactic coordinates determined by CT scanning was performed using target positioner. Accelerator's anteroposterior and lateral portal films were taken using angiographic localizers. The stereotactic coordinates determined by analysis of portal films were compared with the stereotactic coordinates previously determined by CT scanning. Following the correction of discrepancy, the head phantom was irradiated using a stereotactic technique of several arcs. After the irradiation, the film which was sand witched between the phantom sections was developed and the degree of coincidence between the center of the radiation distribution with the target point represented by the hole in the film was measured. In the treatment of actual patients, the way of determining the stereotactic coordinates with CT localizers and angiographic localizers between two sets of coordinates, we proceeded to the irradiation of the actual patient. Results : In the phantom study, the agreement between the center of the radiation distribution and the localized target point was very good. By measuring optical density profiles of the sand witched film along axes that intersected the target point, authors could confirm

Sumitro, Sunaryo; Kurokawa, Shoji; Shimano, Keiji; Wang, Ming L.

2005-06-01

In recent years, many infrastructures have been deteriorating. In order to maintain sustainability of those infrastructures which have significant influence on social lifelines, economical and rational maintenance management should be carried out to evaluate the life cycle cost (LCC). The development of structural health monitoring systems, such as deriving evaluation techniques for the field structural condition of existing structures and identification techniques for the significant engineering properties of new structures, can be considered as the first step in resolving the above problem. New innovative evaluation methods need to be devised to identify the deterioration of infrastructures, e.g. steel tendons, cables in cable-stayed bridges and strands embedded in pre- or post-tensioned concrete structures. One of the possible solutions that show 'AtoE' characteristics, i.e., (a)ccuracy, (b)enefit, (c)ompendiousness, (d)urability and (e)ase of operation, elasto-magnetic (EM) actual stress sensory technology utilizing the sensitivity of incremental magnetic permeability to stress change, has been developed. Numerous verification tests on various steel materials have been conducted. By comparing with load cell, strain gage and other sensory technology measurement results, the actual stresses of steel tendons in a pre-stressed concrete structure at the following stages have been thoroughly investigated: (i) pre-stress change due to set-loss (anchorage slippage) at the tendon fixation stage; (ii) pre-stress change due to the tendon relaxation stage; (iii) concrete creep and shrinkage at the long term pre-stressing stage; (iv) pre-stress change in the cyclic fatigue loading stage; and (v) pre-stress change due to the re-pre-stress setting stage. As the result of this testing, it is confirmed that EM sensory technology enables one to measure actual stress in steel wire, strands and steel bars precisely without destroying the polyethylene covering sheath and enables

van Solinge, Hanna; Henkens, Kène

2018-06-01

This research examined the judgemental process underlying subjective life expectancy (SLE) and the predictive value of SLE on actual mortality in older adults in the Netherlands. We integrated theoretical insights from life satisfaction research with existing models of SLE. Our model differentiates between bottom-up (objective data of any type) and top-down factors (psychological variables). The study used data from the first wave of the Netherlands Interdisciplinary Demographic Institute Work and Retirement Panel. This is a prospective cohort study among Dutch older workers. The analytical sample included 2278 individuals, assessed at age 50-64 in 2001, with vital statistics tracked through 2011. We used a linear regression model to estimate the impact of bottom-up and top-down factors on SLE. Cox proportional hazard regression was used to determine the impact of SLE on the timing of mortality, crude and adjusted for actuarial correlates of general life expectancy, family history, health and trait-like dispositions. Results reveal that psychological variables play a role in the formation of SLE. Further, the results indicate that SLE predicts actual mortality, crude and adjusted for socio-demographic, biomedical and psychological confounders. Education has an additional effect on mortality. Those with higher educational attainment were less likely to die within the follow-up period. This SES gradient in mortality was not captured in SLE. The findings indicate that SLE is an independent predictor of mortality in a pre-retirement cohort in the Netherlands. SLE does not fully capture educational differences in mortality. Particularly, higher-educated individuals underestimate their life expectancy.

Are human mating preferences with respect to height reflected in actual pairings?

Science.gov (United States)

Stulp, Gert; Buunk, Abraham P; Pollet, Thomas V; Nettle, Daniel; Verhulst, Simon

2013-01-01

Pair formation, acquiring a mate to form a reproductive unit, is a complex process. Mating preferences are a step in this process. However, due to constraining factors such as availability of mates, rival competition, and mutual mate choice, preferred characteristics may not be realised in the actual partner. People value height in their partner and we investigated to what extent preferences for height are realised in actual couples. We used data from the Millennium Cohort Study (UK) and compared the distribution of height difference in actual couples to simulations of random mating to test how established mate preferences map on to actual mating patterns. In line with mate preferences, we found evidence for: (i) assortative mating (r = .18), (ii) the male-taller norm, and, for the first time, (iii) for the male-not-too-tall norm. Couples where the male partner was shorter, or over 25 cm taller than the female partner, occurred at lower frequency in actual couples than expected by chance, but the magnitude of these effects was modest. We also investigated another preference rule, namely that short women (and tall men) prefer large height differences with their partner, whereas tall women (and short men) prefer small height differences. These patterns were also observed in our population, although the strengths of these associations were weaker than previously reported strength of preferences. We conclude that while preferences for partner height generally translate into actual pairing, they do so only modestly.

Let's not, and say we would: imagined and actual responses to witnessing homophobia.

Science.gov (United States)

Crosby, Jennifer Randall; Wilson, Johannes

2015-01-01

We compared imagined versus actual affective and behavioral responses to witnessing a homophobic slur. Participants (N = 72) witnessed a confederate using a homophobic slur, imagined the same scenario, or were not exposed to the slur. Those who imagined hearing the slur reported significantly higher levels of negative affect than those who actually witnessed the slur, and nearly one half of them reported that they would confront the slur, whereas no participants who actually heard the slur confronted it. These findings reveal a discrepancy between imagined and real responses to homophobic remarks, and they have implications for the likelihood that heterosexuals will actually confront homophobic remarks.

Background: Fatigue is an important aging mechanism in RPV and it must be contained to aging management working range. Purpose: In order to ensure the safety operation of nuclear power plants, as extension of RPV service time, it is necessary to assess the fatigue damage caused by actual operation transient. Methods: Based on monitoring data of actual operation during the past eleven years, refer to design transient, the statistic analysis for types and occurrence times of actual transient is carried out, at the same time, every transients are combined as different operation cycles and the temperature field and stress field of typical components are analyzed by FEM. Results: Based on these information, fatigue analysis and assessment are finished, if later-actual transients are similar with the previous transients, the calculation result shows that the ratio between maximum of cumulative usage factors and design calculation value is 0.4967 the design transients is conservative. Conclusions: Fatigue status of RPV could be assessed and traced quickly through fatigue status assessment method in this paper based on actual operational transient and assessment result would be a good reference for RPV aging management.

Namazikhah, M S; Ghiai, M; Parkin, M J; Puccinelli, L

2000-06-01

The purpose of this study was to investigate the difference between the radiographic gutta-percha terminus and the actual gutta-percha terminus of human molars by comparing radiographic obturation results with actual obturation results. Forty maxillary palatal roots and 50 mandibular distal roots were randomly selected from a population of 540. They were then mounted in stone and radiographed. Conventional endodontic therapy was completed using stainless-steel K files and lateral condensation. Each radiographic gutta-percha terminus was evaluated under 4.5x magnification by three examiners following the completion of root canal therapy. These results were recorded. Each tooth was then removed from its mounting, and the actual gutta-percha terminus was evaluated under 4.5x magnification. These results were recorded and compared to the radiographic gutta-percha terminus results. In all 90 teeth examined, the actual gutta-percha terminus was equal to or longer than the radiographic gutta-percha terminus. In the 50 mandibular distal roots, the actual gutta-percha terminus averaged 0.645 mm longer than the radiographic gutta-percha terminus. In the 40 maxillary palatal roots, this difference measured 0.6375 mm.

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

Science.gov (United States)

Eyal, Tal; Epley, Nicholas

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.

Monitoring actual temperatures in Susquehanna SES reactor buildings

International Nuclear Information System (INIS)

Derkacs, A.P.

1991-01-01

PP and L has been monitoring temperatures in the Susquehanna SES reactor building with digital temperature recorders since 1986. In early 1990, data from four representative areas was analyzed to determine the temperature in each area which would produce the same rate of degradation as the distribution of actual temperatures recorded over about 40 months. From these effective average temperatures, qualified life multipliers were determined for activation energies in the range of 0.5 to 1.5 and those multipliers were used to estimate new qualified lives and the number of replacements which might be saved during the life of the plant. The results indicate that pursuing a program of determining EQ qualified lives from actual temperatures, rather than maximum design basis temperatures, will provide a substantial payback in reduced EQ driven maintenance

On history dependence of stress-strain diagrams and creep curves under variable repeated loading

International Nuclear Information System (INIS)

Gokhfeld, D.A.; Sadakov, O.S.; Martynenko, M.E.

1979-01-01

The ability of structural alloys to 'keep in memory' the loading prehistory becomes of special importance when inelastic variable repeated loading is considered. There are two main approaches to the development of the mathematical description of this phenomenon: the inclusion of hidden state variables in the incremental theory constitutive equations (a) and construction of proper hereditary functionals (b). In this respect the assumption that the 'memory' regarding the previous deformation history is due to structural nonhomogeneity of actual materials proves to be fruitful. (orig.)

Comparison of actual and predicted routes used in the shipment of radioactive materials

International Nuclear Information System (INIS)

Joy, D.S.; Johnson, P.E.; Harrison, I.G.

1985-01-01

A number of highway controlled shipments of radioactive materials have been made over the past several years. An excellent example showing the variability of actual routes is the transfer of 45 shipments between the Three Mile Island reactor in Pennsylvania and Scoville, Idaho in 1982 and 1983. Six different routes varying between 2273 and 2483 miles were used. Approximately 75% of these shipments followed a common route which passed through ten Urbanized Areas, defined by the Census Bureau as having a population exceeding 100,000 people. Other routes, while shorter in distance, passed through as many as 14 Urbanized Areas. Routes predicted by the Oak Ridge routing model did not exactly duplicate actual routes used. However, the analysis shows that the routing model does make a good estimate of transportation routes actually chosen by shippers of radioactive materials. In actual practice, a number of factors (weather, road conditions, driver preference, etc.) influence the actual route taken. 5 refs., 1 fig., 1 tab

The basic ingredients of the open-quote open-quote consistent histories close-quote close-quote approach to quantum theory are a space UP of open-quote open-quote history propositions close-quote close-quote and a space D of open-quote open-quote decoherence functionals.close-quote close-quote In this article we consider such history quantum theories in the case where UP is given by the set of projectors P(V) on some Hilbert space V. We define the notion of a open-quote open-quote physical symmetry of a history quantum theory close-quote close-quote (PSHQT) and specify such objects exhaustively with the aid of an analog of Wigner close-quote s theorem. In order to prove this theorem we investigate the structure of D, define the notion of an open-quote open-quote elementary decoherence functional,close-quote close-quote and show that each decoherence functional can be expanded as a certain combination of these functionals. We call two history quantum theories that are related by a PSHQT open-quote open-quote physically equivalent close-quote close-quote and show explicitly, in the case of history quantum mechanics, how this notion is compatible with one that has appeared previously. copyright 1996 American Institute of Physics

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.

Criteria for the generation of spectra consistent time histories

International Nuclear Information System (INIS)

Lin, C.-W.

1977-01-01

Several methods are available to conduct seismic analysis for nuclear power plant systems and components. Among them, the response spectrum technique has been most widely adopted for linear type of modal analysis. However, for designs which consist of structural or material nonlinearites such as frequency dependent soil properties, the existance of gaps, single tie rods, and friction between supports where the response has to be computed as a function of time, time history approach is the only viable method of analysis. Two examples of time history analysis are: 1) soil-structure interaction study and, 2) a coupled reactor coolant system and building analysis to either generate the floor response specra or compute nonlinear system time history response. The generation of a suitable time history input for the analysis has been discussed in the literature. Some general guidelines are available to insure that the time history imput will be as conservative as the design response spectra. Very little has been reported as to the effect of the dyanmic characteristics of the time history input upon the system response. In fact, the only available discussion in this respect concerns only with the statitical independent nature of the time history components. In this paper, numerical results for cases using the time history approach are presented. Criteria are also established which may be advantageously used to arrive at spectra consistent time histories which are conservative and more importantly, realistic. (Auth.)

Seismic demand evaluation based on actual earthquake records

International Nuclear Information System (INIS)

Jhaveri, D.P.; Czarnecki, R.M.; Kassawara, R.P.; Singh, A.

1990-01-01

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.

2015-12-01

Full Text Available This study aimed at analyzing Iranian EFL teachers’ beliefs toward classroom management and the relationship between teachers’ beliefs and their actual practices of classroom management in regard with individual variables such as gender, education degree, and teaching experience. The data were collected using a behavior and instructional management scale inventory and direct class observation through a researcher made classroom management observation checklist. The findings showed that EFL teachers favored interactionalist orientation on behavior and instructional management dimensions. Findings also indicated that male teachers were not significantly different from females in terms of the relationship between their beliefs and actual practices. However, there was a significant relationship between teachers’ beliefs and their actual practices of classroom management among less experienced teachers. It was further found that increase in teachers’ educational level led to decrease in discrepancy between their beliefs and actual practices.

Full Text Available OBJECTIVES: To describe the steps of the nursing process as prescribed in the literature and to investigate the process as actually applied in the daily routine of a general hospital. METHODS: Cross-sectional retrospective study (May/June 2005, performed in a hospital in Porto Alegre, RS. Medical records of adult patients admitted to a surgical, clinical or intensive care unit were reviewed to identify the nursing process steps accomplished during the first 48h after admission. The form for data collection was structured according to other reports. RESULTS: 302 medical records were evaluated. Nursing records and physical examination were included in over 90% of them. Nursing diagnosis was not found in any of the records. Among the steps performed, prescription was the least frequent. Evolution of the case was described in over 95% of the records. CONCLUSIONS: All nursing steps recommended in the literature, except for diagnosis, are performed in the research institution.

''Uranium for Moscow''. Highlights of the history of Wismut AG

International Nuclear Information System (INIS)

Karlsch, Rainer

2013-01-01

The Wismut AG was the worldwide largest mining operation for the promotion of uranium ores and the production of chemical uranium concentrates. The author of the contribution under consideration reports on the historical aspects of Wismut AG. In May 1947, Wismut AG was founded as a branch of the State Soviet stock company of the nonferrous metal industry. This branch resided at first in Aue (Saxony, Federal Republic of Germany) and from 1949 in Chemnitz (Saxony, Federal Republic of Germany). By means of the company name Wismut, the actual business purpose should not be disclosed. Until after the end of the Cold War historians could deal with the history of the Wismut AG.

Estimation of moderator temperature coefficient of actual PWRs using wavelet transform

International Nuclear Information System (INIS)

Katsumata, Ryosuke; Shimazu, Yoichiro

2001-01-01

Recently, an applicability of wavelet transform for estimation of moderator temperature coefficient was shown in numerical simulations. The basic concept of the wavelet transform is to eliminate noise in the measured signals. The concept is similar to that of Fourier transform method in which the analyzed reactivity component is divided by the analyzed component of relevant parameter. In order to apply the method to analyze measured data in actual PWRs, we carried out numerical simulations on the data that were more similar to actual data and proposed a method for estimation of moderator temperature coefficient using the wavelet transform. In the numerical simulations we obtained moderator temperature coefficients with the relative error of less than 4%. Based on this result we applied this method to analyze measured data in actual PWRs and the results have proved that the method is applicable for estimation of moderator temperature coefficients in the actual PWRs. It is expected that this method can reduce the required data length during the measurement. We expect to expand the applicability of this method to estimate the other reactivity coefficients with the data of short transient. (author)

Revolutions in energy input and material cycling in Earth history and human history

Lenton, Timothy M.; Pichler, Peter-Paul; Weisz, Helga

2016-04-01

Major revolutions in energy capture have occurred in both Earth and human history, with each transition resulting in higher energy input, altered material cycles and major consequences for the internal organization of the respective systems. In Earth history, we identify the origin of anoxygenic photosynthesis, the origin of oxygenic photosynthesis, and land colonization by eukaryotic photosynthesizers as step changes in free energy input to the biosphere. In human history we focus on the Palaeolithic use of fire, the Neolithic revolution to farming, and the Industrial revolution as step changes in free energy input to human societies. In each case we try to quantify the resulting increase in energy input, and discuss the consequences for material cycling and for biological and social organization. For most of human history, energy use by humans was but a tiny fraction of the overall energy input to the biosphere, as would be expected for any heterotrophic species. However, the industrial revolution gave humans the capacity to push energy inputs towards planetary scales and by the end of the 20th century human energy use had reached a magnitude comparable to the biosphere. By distinguishing world regions and income brackets we show the unequal distribution in energy and material use among contemporary humans. Looking ahead, a prospective sustainability revolution will require scaling up new renewable and decarbonized energy technologies and the development of much more efficient material recycling systems - thus creating a more autotrophic social metabolism. Such a transition must also anticipate a level of social organization that can implement the changes in energy input and material cycling without losing the large achievements in standard of living and individual liberation associated with industrial societies.

"Less than a Vapor": Positioning Black lesbian women in history teacher education.

Science.gov (United States)

Woodson, Ashley N

2017-10-02

In this article, I discuss the possibilities and implications of centering Black lesbian identities and relationships in history teacher education through a case study with one straight Black woman preservice history teacher named Danitra. Danitra's understanding and navigation of historical research on Black lesbians are discussed in relation to core themes of lesbian historiography and emancipatory historiography. Though the literature on this group is limited, I argue that critical considerations of Black lesbians' interests and experiences help educators to conceive of and teach about history, citizenship, justice, and sexuality in more liberatory ways. I conclude by offering recommendations to history teachers and teacher educators who hope to draw on lesbian and emancipatory historiographies to challenge discourses of invisibility in history teacher education classrooms.

A Material History of Electroshock Therapy : Electroshock Technology in Europe until 1945.

Science.gov (United States)

Rzesnitzek, Lara; Lang, Sascha

2016-09-01

The article considers the history of electroshock therapy as a history of medical technology, professional cooperation and business competition. A variation of a history from below is intended; though not from the patients' perspective (Porter, Theory Soc 14:175-198, 1985), but with a focus on electrodes, circuitry and patents. Such a 'material history' of electroshock therapy reveals that the technical make-up of electroshock devices and what they were used for was relative to the changing interests of physicians, industrial companies and mental health politics; it makes an intriguing case for the Social Construction of Technology theory (Bijker et al., The social construction of technological systems: new directions in the sociology and history of technology. MIT Press, Cambridge, MA, 1987).

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.

Stark, Laura; Campbell, Nancy D

2014-12-01

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.

To determine when and how to perform punctoplasty, review the history, and determine the efficacy of posterior ampullectomy. Retrospective analysis of 53 cases of punctal stenosis, operated by a single surgeon by means of posterior ampullectomy via 3-snips. A review of the history of the procedure from papers found with a Medline search for 1-snip, 2-snip, 3-snip, and punctoplasty. In all, 102 sets of notes were reviewed. The age range was from 9 to 89 years with a mean age of 56 years. A total of 74% of patients were female. We excluded 22 patients who had additional surgery and 16 patients who elected not to have surgery. There was no comment as to success or failure in four sets of notes and seven notes could not be found; these cases were also excluded. Of the remaining 53 patients, success was documented in 49 cases, or 92%. The historical review helps explain the debate about the procedure. The retrospective review confirms that posterior ampullectomy via 3-snips is an effective procedure.

2013-09-01

Perception of peer behaviors is an important predictor of actual risk behaviors among youth. However, we lack understanding of peer influence through social media and of actual and perceived peer behavior concordance. The purpose of this research is to document the relationship between individual perception of and actual peer sexual risk behavior using online social networks. The data are a result of a secondary analysis of baseline self-reported and peer-reported sexual risk behavior from a cluster randomized trial including 1,029 persons from 162 virtual networks. Individuals (seeds) recruited up to three friends who then recruited additional friends, extending three waves from the seed. ANOVA models compared network means of actual participant behavior across categories of perceived behavior. Concordance varied between reported and perceived behavior, with higher concordance between perceived and reported condom use, multiple partners, concurrent partners, sexual pressure, and drug and alcohol use during sex. Individuals significantly over-reported risk and under-reported protective peer behaviors related to sex.

Full Text Available Introduction Infertility in men is the important problem, and not only medical, this is the most serious social problems in developed countries. It concerns both the individual and the family, and society in general. Actuality of this problem increases with age. Over the last 20 years the number infertile men rose from 30% to 50%. Male infertility gets 25-50% of all causes of infertility, the share of is. The situation is caused by multi-dimensionality of factors inherent in the present. The most significant are: socio-economic, environmental, lifestyle, marriage and family relations. And although the level of development of modern medicine is very high, often the cause of infertility in men can not be determined. Research objective To analyze the main issues of pathogenesis and diagnosis of male infertility. Materials and methods The next methods were used: the semantic evaluation of scientific documents, comparison, system and structural-logical analysis. Spermatogenesis is a complex process. It is estimated that out of testicular tank sperm contains about 440 million of cells. Male infertility can becaused by the inability of the sperm penetration in mature female egg. Secretory infertility is usually caused by two main reasons. The first- testicles pathology due to congenital or acquired factors. A special place in the development of secretory infertility has endocrine pathology of the hypothalamic-pituitary-gonadal system (congenital and acquired hypogonadism, testosterone-deficient state and diabetes mellitus. Diagnosis of infertility in men is based on medical history, clinical, laboratory and special methods of examination. Conclusions Infertility in men is important problem, and not only medical, this is the most serious social problems in developed countries, which relate both to the individual and the family, and society in general. Spermatogenesis is a complex process, in which primitive germ cells, or spermatogonia, share

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)

Suspect/foil identification in actual crimes and in the laboratory: a reality monitoring analysis.

Science.gov (United States)

Behrman, Bruce W; Richards, Regina E

2005-06-01

Four reality monitoring variables were used to discriminate suspect from foil identifications in 183 actual criminal cases. Four hundred sixty-one identification attempts based on five and six-person lineups were analyzed. These identification attempts resulted in 238 suspect identifications and 68 foil identifications. Confidence, automatic processing, eliminative processing and feature use comprised the set of reality monitoring variables. Thirty-five verbal confidence phrases taken from police reports were assigned numerical values on a 10-point confidence scale. Automatic processing identifications were those that occurred "immediately" or "without hesitation." Eliminative processing identifications occurred when witnesses compared or eliminated persons in the lineups. Confidence, automatic processing and eliminative processing were significant predictors, but feature use was not. Confidence was the most effective discriminator. In cases that involved substantial evidence extrinsic to the identification 43% of the suspect identifications were made with high confidence, whereas only 10% of the foil identifications were made with high confidence. The results of a laboratory study using the same predictors generally paralleled the archival results. Forensic implications are discussed.

Trivial trauma and delayed rupture of a normal spleen: a case report

Directory of Open Access Journals (Sweden)

Sowers Nicholas

2011-12-01

Full Text Available Abstract Introduction Although a majority of splenic ruptures present acutely with a known mechanism of injury, a minority of patients present days to weeks following trauma with a delayed rupture. Also uncommon is the atraumatic rupture, the vast majority of which occur in patients with underlying splenic pathology. A handful of cases of apparently spontaneous rupture of a normal spleen are reported; however, there is debate about whether these actually represent delayed ruptures following a history of trauma that is not elicited. Although a few cases of delayed rupture of the spleen following trivial trauma have been reported, the majority of these present evidence of an underlying disease process. We found only two such cases that documented a normal spleen and three cases where underlying splenic pathology was not reported. We review the literature and discuss the phenomenon of delayed rupture of the normal spleen following trivial trauma. Case presentation A 27-year-old Caucasian man with no underlying splenic pathology presented with splenic rupture one week after playfully wrestling with his partner. The patient did not present at the time of the injury and only recalled it upon repeated questioning after computed tomography diagnosis. Conclusions This case lends support to the theory that the normal spleen can rupture some time after trivial trauma, which seems like a more plausible explanation than rupture without cause. However, given the dearth of similar reports in the literature, the possibility remains that the association we have observed is not causational.

As a critical component of the energy and water cycle, terrestrial actual evapotranspiration (ET) can be influenced by many factors. This study was mainly devoted to providing accurate and continuous estimations of actual ET for the Tibetan Plateau (TP) and analyzing the effects of its impact factors. In this study, summer observational data from the Coordinated Enhanced Observing Period (CEOP) Asia-Australia Monsoon Project (CAMP) on the Tibetan Plateau (CAMP/Tibet) for 2003 to 2004 was selected to determine actual ET and investigate its relationship with energy, hydrological, and dynamical parameters. Multiple-layer air temperature, relative humidity, net radiation flux, wind speed, precipitation, and soil moisture were used to estimate actual ET. The regression model simulation results were validated with independent data retrieved using the combinatory method. The results suggested that significant correlations exist between actual ET and hydro-meteorological parameters in the surface layer of the Nagqu river basin, among which the most important factors are energy-related elements (net radiation flux and air temperature). The results also suggested that how ET is eventually affected by precipitation and two-layer wind speed difference depends on whether their positive or negative feedback processes have a more important role. The multivariate linear regression method provided reliable estimations of actual ET; thus, 6-parameter simplified schemes and 14-parameter regular schemes were established.

STUDY ON THE CROSS WAR FOR INTERNALIZING VALUES OF TOLERANCE IN HISTORY LEARNING

Directory of Open Access Journals (Sweden)

2017-05-01

Full Text Available As we know that history is series of events that occurred which its presence must be motivated by specific causes. History does not appear immediately and stand alone without anyone arousing it. It can be said that history has a prologue and epilogue, because not all of the events that happened in the past can be recorded by history. In this topic being discussed, a crusade became the reality of the history of mankind, which had taken more or less for two hundred years. The War was the greatest conflict of two religions in the world which was between Islam that held the power at that time in part of Europe, North Africa and Asia, against the followers of Christianity who tried to seize the city of Jerusalem, which at that time ruled by Islam, the postscript is a holy city for them. Islam and Christianity are the major religions in the world that their religious teachings heavily loaded with the values of peace, tolerance and social relationships. Both in the Qur'an and Gospel, there are a lot of passages of calls for tolerance, peace and social relations. This creates a question, why the war should happen, in terms of Islam encountered in a call for dialogue with the People of the Book in a good way, as well as in Christianity which is expressed as a neighbor. Islam also considers that the Christians are a people who are closest to the Islamic ummah, and both religions actually are brothers, free from hostility and enmity.

Criteria for the generation of spectra consistent time histories

International Nuclear Information System (INIS)

Lin, C.-W.

1977-01-01

There are several approaches currently being used by the nuclear industry to generate design time history input. None of these produce unique results. That is, given a design response spectrum, nearly unlimited number of synthesized time history motions can be constructed. The effects of these time history motions on the system response vary and they have not been properly evaluated. For instance, some time histories may have high frequency content, higher than indicated by the real earthquake records. This may have adverse influence on the system response with high frequency impact or predominate high frequency modes. Other time histories may have unnecessarily long duration which makes a large and detailed analytical model uneconomical. The influence of the time history duration is primarily on the number of peak response stress cycles computed which can be either extrapolated from limited duration input or determined using other means. Rarely is the case that duration has to be kept long enough for the structure response to reach its peak. Consequently, input duration should be kept no longer than necessary to produce peak response to allow the use of more sophisticated model which enables the problem to be studied thoroughly. There are also time histories which have satisfied the generally accepted definition of statistical independent requirements, but possess statistical characteristics unlike those of the real earthquakes. Finally, some time histories may require smaller integration time steps than ordinarily used to insure that certain systems will have converge and stable solutions

Badal-Valero, Elena; Alvarez-Jareño, José A; Pavía, Jose M

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.

Acute lymphoblastic leukemia/lymphoma (ALL) in adults is a rare malignancy with a poor clinical outcome, and few reported etiologic risk factors. We performed an exploratory pooled study of 152 ALL cases and 23096 controls from 16 case-control studies to investigate the role of medical history, lifestyle, family history, and occupational risk factors and risk of ALL. Age- race/ethnicity-, sex-, and study-adjusted odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using logistic regression. An increased risk of ALL was found in those with a family history of a hematological malignancy (OR = 2.6, 95% CI = 1.22 to 5.54) and in leather (OR = 3.91, 95% CI = 1.35 to 11.35) and sewing/embroidery workers (OR = 2.92, 95% CI = 1.00 to 8.49). Consumers of alcohol had an increased risk of B-cell ALL (OR = 2.87, 95% CI = 1.18 to 6.95). The small number of statistically significant risk factors identified out of the 112 variables examined could be chance findings and will require further replication to assess their role in the etiology of adult ALL. © The Author 2014.

Background. The differential diagnosis of primary breast tuberculosis with other benign or malignant conditions can be difficult with the current imaging techniques that used to recognize breast pathologies. In many cases mammographic and ultrasound characteristics of breast tuberculosis are similar to those of breast cancer. Case report. We present a case of primary breast tuberculosis, with no previous history of the disease, which was diagnosed during the operation. Conclusions. Primary breast tuberculosis can be misdiagnosed. In these cases a tuberculosis infection history is negative, the mammographic and radiological findings obscure and the mass can be misdiagnosed as carcinoma. The diagnosis is achieved after the surgical removal of the mass and histological examination of the specimen. (author)

Some Recent Developments in the Endochronic Theory with Application to Cyclic Histories

1983-01-01

Constitutive equations with only two easily determined material constants predict the stress (strain) response of normalized mild steel to a variety of general strain (stress) histories, without a need for special unloading-reloading rules. The equations are derived from the endochronic theory of plasticity of isotropic materials with an intrinsic time scale defined in the plastic strain space. Agreement between theoretical predictions and experiments are are excellent quantitatively in cases of various uniaxial constant amplitude histories, variable uniaxial strain amplitude histories and cyclic relaxation. The cyclic ratcheting phenomenon is predicted by the present theory.

2015-12-01

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 aim of the paper was to present the case of a patient who developed acute psychotic symptoms on her visit to Jerusalem. The analysis of the clinical case and medical history. The presented 62-year-old women with a history of previous psychiatric disorder arrived with her husband to Jerusalem as a part of organised touristic group. She developed acute psychotic reaction through some stages characteristic for the third type of Jerusalem syndrome. Symptoms resolved completely soon after returning to Poland and admission to the hospital where an antipsychotic treatment was performed. Despite the rare occurrence of this phenomenon, it is worth noting that we can divide Jerusalem syndrome into three types depending on its clinical course, patient's history of previous psychiatric disorders and this division has some clinical implications. This syndrome can be also considered in the context of some factors connected with travelling in general which may be responsible for psychiatric disturbances occurring among travelers. The course of psychiatric disturbances in the presented patient resembled the third type of Jerusalem syndrome despite her past psychiatric history and probably travelling caused her decompensations. In clinical practice we have to remember that in case of the patients with a known psychiatric history, clinical evaluation may be useful before travelling. In previously healthy patients developing the third type of the Jerusalem syndrome early intervention and separation from Jerusalem and its holy places and their contact with family are crucial for soon recovery.

Farmland Tenure Security in China: Influencing Factors of Actual and Perceived Farmland Tenure Security

Science.gov (United States)

Ren, Guangcheng; Zhu, Xueqin; Heerink, Nico; van Ierland, Ekko; Feng, Shuyi

2017-04-01

Tenure security plays an important role in farm households' investment, land renting and other decisions. Recent literature distinguishes between actual farmland tenure security (i.e. farm households' actual control of farmland) and perceived farmland tenure security (i.e. farm households' subjective understanding of their farmland tenure situation and expectation regarding government enforcement and equality of the law). However little is known on what factors influence the actual and perceived farmland tenure security in rural China. Theoretically, actual farmland tenure security is related to village self-governance as a major informal governance rule in rural China. Both economic efficiency and equity considerations are likely to play a role in the distribution of land and its tenure security. Household perceptions of farmland tenure security depend not only on the actual farmland tenure security in a village, but may also be affected by households' investment in and ability of changing social rules. Our study examines what factors contribute to differences in actual and perceived farmland tenure security between different villages and farm households in different regions of China. Applying probit models to the data collected from 1,485 households in 124 villages in Jiangsu, Jiangxi, Liaoning and Chongqing, we find that development of farmland rental market and degree of self-governance of a village have positive impacts, and development of labour market has a negative effect on actual farmland tenure security. Household perceptions of tenure security depend not only on actual farmland tenure security and on households' investment in and ability of changing social rules, but also on risk preferences of households. This finding has interesting policy implications for future land reforms in rural China.

To raise awareness for surgeons encountering bariatric patients with anatomy that deviates from the standard Roux-en-Y gastric bypass (RYGB). This is a single-institution retrospective case series over 12 years (2003-2014) involving patients who believed they received RYGBs, but actually did not. Data was obtained reviewing physician encounters, imaging, and operative reports. There were six cases with confusing clinical pictures, found to have aberrant RYGB anatomy: (1) gastric bypass with jejuno-jejunostomy only without gastrojejunostomy, (2) distal partial vertical gastrectomy without expected prosthetic band, (3) inverse vertical banded gastroplasty, (4) non-divided gastric bypass with no gastrojejunostomy, (5) 20-cm Roux limb, with gastro-gastric fistula, and (6) 200-cm bilio-pancreatic limb similar to the traditional Scopinaro procedure. There are cases of "Roux-en-Y gastric bypasses" that have no resemblance to the named procedure at all. Adjunctive upper gastrointestinal studies and upper endoscopies help surgeons make diagnoses that are incongruent with the surgical history. It is important to keep in mind that there could be anatomic or surgical variations which were born out of necessity or based on other surgeons' creativities.

Full Text Available Este trabajo presenta las características e historia del software para crear y gestionar bibliotecas digitales Greenstone, desarrollado inicialmente por la Universidad de Waikato, Nueva Zelandia en 1997. 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.

Primary Dermal Melanoma in a Patient with a History of Multiple Malignancies: A Case Report with Molecular Characterization

Directory of Open Access Journals (Sweden)

2013-07-01

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.

The two principal lines of thought...... on short-term prediction (mathematical and physical) are indistinctly treated here and comparisons between models and tools are avoided, mainly because, on the one hand, a standard for a measure of performance is still not adopted and, on the other hand, it is very important that the data are exactly...

SEBAL-based Daily Actual Evapotranspiration Forecasting using Wavelets Decomposition Analysis and Multivariate Relevance Vector Machines

Agricultural lands are sources of food and energy for population around the globe. These lands are vulnerable to the impacts of climate change including variations in rainfall regimes, weather patterns, and decreased availability of water for irrigation. In addition, it is not unusual that irrigated agriculture is forced to divert less water in order to make it available for other uses, e.g. human consumption and others. As part of implementation of better policies for water control and management, irrigation companies and water user associations have been implemented water conveyance and distribution monitoring systems along with soil moisture sensors networks in the last decades. These systems allow them to manage and distribute water among the users based on their requirements and water availability while collecting information about actual soil moisture conditions in representative crop fields. In spite of this, requested water deliveries by farmers/water users is based typically on total water share, traditions and past experience on irrigation, which in most cases do not correspond to the actual crop evapotranspiration, already affected by climate change. Therefore it is necessary to provide actual information about the crop water requirements to water users/managers, so they can better quantify the required vs. available water for the irrigation events along the irrigation season. To estimate the actual evapotranspiration in a spatial extent the Sensitivity Analysis of the Surface Energy Balance Algorithm for Land (SEBAL) algorithm has demonstrated its effectiveness using satellite or airborne data. Nonetheless the estimation is restricted to the day when the geospatial information was obtained. Without information of precise future daily water crop demand there is a continuous challenge for the implementation of better water distribution and management policies in the irrigation system. The purpose of this study is to investigate the plausibility of using

Rhetoric and History in Brian Friel’s Making History

Directory of Open Access Journals (Sweden)

Manfredi Bernardini

2014-05-01

Full Text Available This paper proposes an analysis of the rhetorical devices of representation and recording of history, investigated and deconstructed by the so-called "history play" Making History, written by Brian Friel and performed by the Field Day Theatre Company in 1988. The play tells of the heroic deeds of Hugh O’ Neill, a Sixteenth century Ulster gaelic Lord, intertwining his personal facts with the crucial events in Irish History. Friel rediscovers a paradigmatic figure in Irish history, using the theatrical performance in order to dissect and thoroughly scrutinize the basis for the nationalist rhetoric which is at the root of contemporary conflicts in Northern Ireland. Starting from the theoretical contributions of seminal authors such as Hayden White, Paul Ricoeur, Walter Benjamin, Michel De Certeau, the northern Irish playwright challenges the supposedly scientific nature of History, that would decidedly mark it as different from other forms of narrative, such as literature. Hence History’s metalinguistic nature, based on specific rhetorical strategies, is uncovered.  Therefore, on the one hand Friel questions the theoretical foundations of History, of its “grand narratives”,  giving ‘stories’ the chance to be part of official History’s discourse. On the other hand, he lifts the veil on the rhetorical (and in some ways ideological mechanisms involved in the process of History writing, through the character of archbishop Peter Lombard - O’ Neill’s biographer, storyteller and master in elocutio - and sheds light on how History is a form of rhetorical narrative, almost a patchwork of events collected (inventio and assembled (dispositio by the historian according to specific criteria of representation. By taking us inside the very nucleus of the rhetorical devices used by storiography, Friel unmasks the delicate processes of making and unmaking history, the ones that help give birth to identity as well as History.

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.

A novel method of rapidly modeling optical properties of actual photonic crystal fibres

Li-Wen, Wang; Shu-Qin, Lou; Wei-Guo, Chen; Hong-Lei, Li

2010-01-01

The flexible structure of photonic crystal fibre not only offers novel optical properties but also brings some difficulties in keeping the fibre structure in the fabrication process which inevitably cause the optical properties of the resulting fibre to deviate from the designed properties. Therefore, a method of evaluating the optical properties of the actual fibre is necessary for the purpose of application. Up to now, the methods employed to measure the properties of the actual photonic crystal fibre often require long fibre samples or complex expensive equipments. To our knowledge, there are few studies of modeling an actual photonic crystal fibre and evaluating its properties rapidly. In this paper, a novel method, based on the combination model of digital image processing and the finite element method, is proposed to rapidly model the optical properties of the actual photonic crystal fibre. Two kinds of photonic crystal fibres made by Crystal Fiber A/S are modeled. It is confirmed from numerical results that the proposed method is simple, rapid and accurate for evaluating the optical properties of the actual photonic crystal fibre without requiring complex equipment.

A family history of pancreatic cancer has consistently been associated with increased risk of pancreatic cancer. However, uncertainty remains about the strength of this association. Results from previous studies suggest a family history of select cancers (i.e. ovarian, breast, and colorectal) could also be associated, although not as strongly, with increased risk of pancreatic cancer. We examined the association between a family history of five types of cancer (pancreas, prostate, ovarian, breast, and colorectal) and risk of pancreatic cancer using data from a collaborative nested case-control study conducted by the Pancreatic Cancer Cohort Consortium. Cases and controls were from cohort studies from the United States, Europe, and China, and a case-control study from the Mayo Clinic. Analyses of family history of pancreatic cancer included 1,183 cases and 1,205 controls. A family history of pancreatic cancer in a parent, sibling, or child was associated with increased risk of pancreatic cancer (multivariate-adjusted OR = 1.76, 95% CI 1.19–2.61). A family history of prostate cancer was also associated with increased risk (OR = 1.45, 95% CI 1.12–1.89). There were no statistically significant associations with a family history of ovarian cancer (OR = 0.82, 95% CI 0.52–1.31), breast cancer (OR = 1.21, 95% CI 0.97–1.51), or colorectal cancer (OR = 1.17, 95% CI 0.93–1.47). Our results confirm a moderate sized association between a family history of pancreatic cancer and risk of pancreatic cancer and also provide evidence for an association with a family history of prostate cancer worth further study.

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.

Knowledge concerning the medical history prior to the onset of complex regional pain syndrome (CRPS) might provide insight into its risk factors and potential underlying disease mechanisms. To evaluate prior to CRPS medical conditions, a case-control study was conducted in the Integrated Primary Care Information (IPCI) project, a general practice (GP) database in the Netherlands. CRPS patients were identified from the records and validated through examination by the investigator (IASP criteria) or through specialist confirmation. Cases were matched to controls on age, gender and injury type. All diagnoses prior to the index date were assessed by manual review of the medical records. Some pre-specified medical conditions were studied for their association with CRPS, whereas all other diagnoses, grouped by pathogenesis, were tested in a hypothesis-generating approach. Of the identified 259 CRPS patients, 186 cases (697 controls) were included, based on validation by the investigator during a visit (102 of 134 visited patients) or on specialist confirmation (84 of 125 unvisited patients). A medical history of migraine (OR: 2.43, 95% CI: 1.18-5.02) and osteoporosis (OR: 2.44, 95% CI: 1.17-5.14) was associated with CRPS. In a recent history (1-year before CRPS), cases had more menstrual cycle-related problems (OR: 2.60, 95% CI: 1.16-5.83) and neuropathies (OR: 5.7; 95% CI: 1.8-18.7). In a sensitivity analysis, including only visited cases, asthma (OR: 3.0; 95% CI: 1.3-6.9) and CRPS were related. Psychological factors were not associated with CRPS onset. Because of the hypothesis-generating character of this study, the findings should be confirmed by other studies.

THE POPULATION'S ECONOMIC EDUCATION IN THE ROMANIAN ACTUALITY

Full Text Available This paper aims at to present the essence and the role of economic education related to the natural movement of a functioning market economy in the Romanian actuality. We understand education as an important form of social consciousness in the sense of bipolarity, namely as the premise and the effect at a dynamic microeconomic and macroeconomic level. In this dynamic movement, economic education appears more and more visibly as a new factor of production or as a new dimension of human capital. In our approach we consider several theoretical and methodological axes that allow us to reveal the interdependence of education to the economic and social development, from an emulative or frantic perspective. In this way we treat the evolution of complex phenomena of economic education in terms of public policy, highlighting the need to intensify the decision-making efforts of management and execution, consistent pursuing to link the causes with the effects of economic education in the Romanian actuality.

Development case histories: Tongonan and Palinpinon geothermal fields, Philippines

International Nuclear Information System (INIS)

Ogena, M.S.

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
