Short-term energy outlook annual supplement, 1993

International Nuclear Information System (INIS)

1993-01-01

The Energy Information Administration (EIA) prepares quarterly, short-term energy supply, demand, and price projections for publication in February, May, August, and November in the Short-Term Energy Outlook (Outlook). An annual supplement analyzes the performance of previous forecasts, compares recent cases with those of other forecasting services, and discusses current topics related to the short-term energy markets. (See Short-Term Energy Outlook Annual Supplement, DOE/EIA-0202.) The forecast period for this issue of the Outlook extends from the third quarter of 1993 through the fourth quarter of 1994. Values for the second quarter of 1993, however, are preliminary EIA estimates (for example, some monthly values for petroleum supply and disposition are derived in part from weekly data reported in the Weekly Petroleum Status Report) or are calculated from model simulations using the latest exogenous information available (for example, electricity sales and generation are simulated using actual weather data). The historical energy data are EIA data published in the Monthly Energy Review, Petroleum Supply Monthly, and other EIA publications. Minor discrepancies between the data in these publications and the historical data in this Outlook are due to independent rounding

2002-04-01

The history of quartz crystal growth is reviewed from the origin to the industrialization. The developing process of growth techniques is divided into the following three stages: (1) The fundamental work based on the mineralogical genetic view point, which was performed in Italy during the end of the 19th to the beginning of the 20th centuries. (2) The works to attempt the industrial application made in Germany and in England during World War II. (3) The industrialization of quartz growth after World War II. These were initiated in England, in USA and independently in Russia. The highest mass production process was developed in Japan. The historical flow is traced by the interview of several persons based on the original references.

Review of short wavelength lasers

International Nuclear Information System (INIS)

Hagelstein, P.L.

1985-01-01

There has recently been a substantial amount of research devoted to the development of short wavelength amplifiers and lasers. A number of experimental results have been published wherein the observation of significant gain has been claimed on transitions in the EUV and soft x-ray regimes. The present review is intended to discuss the main approaches to the creation of population inversions and laser media in the short wavelength regime, and hopefully aid workers in the field by helping to provide access to a growing literature. The approaches to pumping EUV and soft x-ray lasers are discussed according to inversion mechanism. The approaches may be divided into roughly seven categories, including collisional excitation pumping, recombination pumping, direct photoionization and photoexcitation pumping, metastable state storage plus optical pumping, charge exchange pumping, and finally, the extension of free electron laser techniques into the EUV and soft x-ray regimes. 250 references

Significant sociopolitical changes in recent decades have not only influenced the nursing profession, but also the entire Iranian healthcare system. This study describes the historical evolution of the nursing profession within a sociopolitical context. This historical review of unpublished and published literature endorsed personal accounts of historic events by 14 of the oldest nurses in Iran chosen through purposive sampling method, as they shared their nursing experiences. Individual recollections were collected through in-depth and semi-structured interviews and later analyzed through oral history analysis method. From the results, the 3 categories of the White Revolution, the Islamic Revolution, and Iran-Iraq war and 8 subcategories emerged, where participants identified factors that fundamentally changed the Iranian nursing profession. The nursing profession continues to develop and help revise policies to improve the healthcare system and quality of care. The findings of this study facilitate the better understanding of the influence of sociopolitical events on the nursing profession and guide the revision or development of new healthcare policies.

Historical ESWT Paradigms Are Overcome: A Narrative Review

2016-01-01

Extracorporeal Shock Wave Therapy (ESWT) is a conservative treatment modality with still growing interest in musculoskeletal disorders. This narrative review aims to present an overview covering 20-year development in the field of musculoskeletal ESWT. Eight historical paradigms have been identified and put under question from a current perspective: energy intensity, focus size, anesthesia, imaging, growth plates, acuteness, calcifications, and number of sessions. All paradigms as set in a historical consensus meeting in 1995 are to be revised. First, modern musculoskeletal ESWT is divided into focused and radial technology and the physical differences are about 100-fold with respect to the applied energy. Most lesions to be treated are easy to reach and clinical focusing plays a major role today. Lesion size is no longer a matter of concern. With the exception of nonunion fractures full, regional, or even local anesthesia is not helpful in musculoskeletal indications. Juvenile patients can also effectively be treated without risk of epiphyseal damage. Further research is needed to answer the question about if and which acute injuries can be managed effectively. Treatment parameters like the number of sessions are still relying on empirical data and have to be further elucidated. PMID:27493955

The naming of the cranial nerves: a historical review.

Science.gov (United States)

Davis, Matthew C; Griessenauer, Christoph J; Bosmia, Anand N; Tubbs, R Shane; Shoja, Mohammadali M

2014-01-01

The giants of medicine and anatomy have each left their mark on the history of the cranial nerves, and much of the history of anatomic study can be viewed through the lens of how the cranial nerves were identified and named. A comprehensive literature review on the classification of the cranial names was performed. The identification of the cranial nerves began with Galen in the 2nd century AD and evolved up through the mid-20th century. In 1778, Samuel Sömmerring, a German anatomist, classified the 12 cranial nerves as we recognize them today. This review expands on the excellent investigations of Flamm, Shaw, and Simon et al., with discussion of the historical identification as well as the process of naming the human cranial nerves.

Historical Medical Value of Donguibogam

Directory of Open Access Journals (Sweden)

Bong-Keun Song

2016-03-01

Full Text Available Oriental medicine, since its origin in China, has had a long history extending over 2000 years. Today, it comprises several types of medicine predominately practiced in East Asia, including traditional Chinese, traditional Korean, and Kampo medicine. The distinctive medical system of traditional Korean medicine was established shortly after the publication of Donguibogam by Dr. Heo Jun in 1613. Donguibogam is highly acclaimed across East Asia; in 2009, in light of its historical medical value, the United Nations Educational, Scientific, and Cultural Organization registered the book on its cultural heritage list. Here, we review the historical medical value of Donguibogam. The findings confirm that Donguibogam developed a unique and independent form of traditional Korean medicine and innovatively reformed the disease classification system. Moreover, Donguibogam emphasized the importance of disease prevention and medical pragmatism. This book also accelerated the development of folk medicine. Owing to its historical medical value, Donguibogam is now considered the 'bible' of Oriental medicine. Its wide acceptance has contributed to the expansion of Korean medicine utilization among the general public. Donguibogam has also played an important role in the establishment of traditional Korean medicine as a universally valid and original form of medicine, independent of traditional Chinese medicine.

[Historical trauma. Systematic review of a different approach to armed conflict].

2015-01-01

Historical trauma (HT) is a collective trauma inflicted on a group of people who share an identity or affiliation, and is often characterized by the transgenerational legacy of traumatic experiences, and expressed through various psychological and social responses. This construct is proposed in contrast to post-traumatic stress disorder (PTSD) due to limitations identified with the latter diagnostic category when addressing collective trauma, especially in situations of political and social violence. The purpose of this article is to review the literature published so far on HT. A search was performed using the terms "historical trauma" and "mental health" or "trauma histórico" and "salud mental" in the scientific databases, EMBASE, Ebscohost, JSTOR, ProQuest, LILACS, SciELO, PsycARTICLES, ISI Web of Science and PubMed. The authors reviewed HT definition, paramount characteristics of its traumatic experience, and several theories of on the transgenerational succession if these experiences occur, as well as possible consequences of traumatic events at individual, family and social level. Common characteristics of different therapeutic models are highlighted, in addition to some recommendations for their application. PTSD has clear limitations in addressing community and cumulative traumatic experiences related to specific social and historical contexts. The authors discuss the potential utility of HT in this task. Finally, several gaps in current knowledge regarding this construct are mentioned, and some recommendations for future research are indicated. Copyright © 2014 Asociación Colombiana de Psiquiatría.

A short history of Japanese historical seismology: past and the present

Science.gov (United States)

Matsu'ura, Ritsuko S.

2017-12-01

Since seismicity in Japan is fairly high, Japanese interest in historical seismicity can be traced back to the nineth century, only a few centuries after the formation of the ancient ruling state. A 1000 years later, 2 years earlier than the modern seismological society was founded, the research on historical seismology started in Japan in 1878. By the accumulation for the recent 140 years, the present Japanese seismologists can read many historical materials without reading cursive scripts. We have a convenient access to the historical information related to earthquakes, in the modern characters of 27,759 pages. We now have 214 epicenters of historical earthquakes from 599 ad to 1872. Among them, 134 events in the early modern period were assigned hypocentral depths and proper magnitudes. The intensity data of 8700 places by those events were estimated. These precise intensity data enabled us to compare the detailed source areas of pairs of repeated historical earthquakes, such as the 1703 Genroku earthquake with the 1923 Kanto earthquake, and the 1707 Hoei earthquake with the summation of the 1854 Ansei Tokai and Ansei Nankai earthquakes. It is revealed that the focal area of the former larger event cannot completely include those of the latter smaller earthquakes, although those were believed to be typical sets of characteristic interplate earthquakes at the Sagami trough and at the Nankai trough. Research on historical earthquakes is very important to assess the seismic hazard in the future. We still have one-fifth events of the early modern period to be analyzed in detail. The compilation of places experienced high intensities in the modern events is also necessary. For the ancient and medieval periods, many equivocal events are still left. The further advance of the interdisciplinary research on historical seismology is necessary.

Short-term energy outlook: Quarterly projections, Third quarter 1992

2018-02-01

Acute pancreatitis is one of most common causes of consultation due to abdominal pain in medical emergency units and it requires hospital admission. Although the majority of cases are mild and patients tend to recover quickly, a small percentage of cases is severe, with mortality in the region of 5-10%. This historical review considers how our understanding of this disease has changed since it was first described in 1579 thanks to the contributions of renowned experts such as Nicolaes Tulp, Reginald Fitz, Nicholas Senn and many others who, through their expertise and dedication, have improved the survival of patients with this disease.

Review Essay: Grenzgänger Seeks Reflexive Methodology

Wolff-Michael Roth

2002-09-01

Full Text Available Reflexive Methodology reviews major strands of current thought in epistemology, philosophy, social science, and interpretive methods. The book falls short in that it neither does a thorough job reviewing the literature nor does it provide method-related advice useful to students. Grenzgängerin constitutes a collection of essays on a broad range of topics, but which are only loosely connected if at all. Drawing on DERRIDA and the notion of a historical science of the historical subject, I attempt to practice method, something I missed in both texts. I make explicit the historical nature of my own writing and the historical nature of my subject. I make explicit intertextuality and in the process practice reflexivity in the particular way I am writing. URN: urn:nbn:de:0114-fqs020328

Controversies in nursing ethics: a historical review.

Science.gov (United States)

Olsen, D P

1992-09-01

The author critiques the dialectic between justice-based ethics and an ethic of caring from a historical perspective (by analogy with the dialectic between agape and friendship). Justice-based ethics have been problematic for nursing because of the decontextualized approach. The ethic of caring is problematic because caring, being contextual, is particularistic and therefore can be based on morally irrelevant factors, such as liking. There is a tradition of writing which seeks to reconcile the particularistic obligations of friendship with the moral duty to all others equally. Ideas from the following authors are reviewed for relevance to nursing: Aristotle, Aelred of Rievaulx, Augustine, John Cassian, Cicero, George Berkeley, Immanuel Kant, Michel de Montaigne, Jeremy Taylor and Max Weber. The authors concludes by noting that both sides of the dialectic are synthesized in the lived experience of individuals. A synthesis in thought is called for on this basis.

This approach has shown to be effective in the promotion of better mother-father-infant relationship in the presence of maternal depressive symptoms.

Luminescence dating of some historical/pre-historical natural hazards of India

International Nuclear Information System (INIS)

Gartia, R.K.

2008-01-01

The Indian sub-continent is characterized by host of natural hazards like earthquake, tsunami, cyclones, floods, landslides/mudflows. It is necessary to build-up a database of historical/pre-historical natural hazards for planning scenarios for emergency response to various them. In short, there is a vast scope of providing chronology to hazardous events by using known techniques of dating including luminescence dating which has an excellent window span down from few hundred years to one hundred thousand years. In this work we report the dates of some historical/pre-historical natural hazards of India. In particular we focus on three kinds of natural hazards namely, earthquakes, tsunami, and mudflows. For example of earthquake we cover a historical earthquake of Manipur that created two massive fissures at Kumbi, 25 km from the state capital, Imphal. For pre-historical ones, we cover Assam-Shillong area known for its highest levels of seismicity in India. We demonstrate the evidence of a paleo-tsunami that devastated Mahabalipuram near Chennai. Incidentally, Mahabalipuram was badly affected by the great tsunami of 26th Dec 2004. Finally, luminescence dating technique has been applied to some historical/pre-historical mudflows of Manipur. A recent mudflow on 10th July 2004 damaged more than 90 houses, block National Highway-39, the life-line of Manipur for more than a fort-night. (author)

Full Text Available The issue of history and historicity is reviewed in this article. The efforts of New Historicism is brought to bear on this question in an effort to find a way out of the impasse created by the modernist demand for objectivity and the postmodern resignation to radical relativism. The possibility of historiography is explored in conjunction with the pragmatic approach and leads to the conclusion that a kind of historical knowledge is attainable which can be described as useful even if not perfect. The author concurs with Crossan and his working definition of history as the past reconstructed interactively by the present through argued evidence in public discourse. The intersubjective nature of any historical enterprise leads the author to the conclusion that the search for the historical Jesus can only be done in the dialectical approach of a both ... and: both the historical Jesus and the kerygmatic Christ

A Historical Review of Diachrony and Semantic Dimensions of Trace in Neurosciences and Lacanian Psychoanalysis

KAUST Repository

Escobar, Carolina

2017-06-23

Experience leaves a trace in the nervous system through plasticity. However, the exact meaning of the mnesic trace is poorly defined in current literature. This article provides a historical review of the term trace in neuroscience and psychoanalysis literature, to highlight two relevant aspects: the diachronic and the semantic dimensions.

Historical literature review on waste classification and categorization

Energy Technology Data Exchange (ETDEWEB)

Croff, A.G.; Richmond, A.A.; Williams, J.P.

1995-03-01

The Staff of the Waste Management Document Library (WMDL), in cooperation with Allen Croff have been requested to provide information support for a historical search concerning waste categorization/classification. This bibliography has been compiled under the sponsorship of Oak Ridge National Laboratory`s Chemical Technology Division to help in Allen`s ongoing committee work with the NRC/NRCP. After examining the search, Allen Croff saw the value of the search being published. Permission was sought from the database providers to allow limited publication (i.e. 20--50 copies) of the search for internal distribution at the Oak Ridge National Laboratory and for Allen Croff`s associated committee. Citations from the database providers who did not grant legal permission for their material to be published have been omitted from the literature review. Some of the longer citations have been included in an abbreviated form in the search to allow the format of the published document to be shortened from approximately 1,400 pages. The bibliography contains 372 citations.

Historical ecology: past, present and future.

Science.gov (United States)

Szabó, Péter

2015-11-01

The term 'historical ecology' has been used with various meanings since the first half of the 20th century. Studies labelled as historical ecology have been produced in at least four academic disciplines: history, ecology, geography and anthropology. Although all those involved seem to agree that historical ecology concerns the historical interconnectedness of nature and human culture, this field of study has no unified methodology, specialized institutional background and common publication forums. Knowledge of the development of historical ecology is also limited. As a result, the current multitude of definitions of historical ecology is accompanied by divergent opinions as to where the origins of the field are to be sought. In this review, I follow the development of historical ecology from the 18th century to the present. In the first part, I briefly describe some early examples of historical ecological investigations, followed by a description of the various scientific strands in the 20th century that contributed to the formation of historical ecology. In the second part, I discuss the past five decades of historical ecological investigations in more detail, focusing mostly (but not exclusively) on works that their respective authors identified as historical ecology. I also examine the appearance and interconnectedness of the two main trends (ecological and anthropological) in historical ecological research. In the last part, I attempt to outline the future of historical ecology based on common features in existing research. It appears that at present historical ecology is at a crossroads. With rapidly growing interest in historical ecological research, it may move towards institutionalization or remain an umbrella term. © 2014 The Authors.

Short-term energy outlook. Quarterly projections, first quarter 1995

International Nuclear Information System (INIS)

1995-02-01

The Energy Information Administration (EIA) prepares quarterly, short-term energy supply, demand, and price projections for publication in February, May, August, and November in the Short-Term Energy Outlook (Outlook). The forecast period for this issue of the Outlook extends from the first quarter of 1995 through the fourth quarter of 1996. Values for the fourth quarter of 1994, however, are preliminary EIA estimates or are calculated from model simulations using the latest exogenous information available (for example, electricity sales and generation are simulated using actual weather data). The historical energy data, compiled into the first quarter 1995 version of the Short-Term Integrated Forecasting System (STIFS) database, are mostly EIA data regularly published in the Monthly Energy Review, Petroleum Supply Monthly, and other EIA publications. Minor discrepancies between the data in these publications and the historical data in this Outlook are due to independent rounding. The STIFS database is archived quarterly and is available from the National Technical Information Service. The cases are produced using the Short-Term Integrated Forecasting System (STIFS). The STIFS model is driven principally by three sets of assumptions or inputs: estimates of key macroeconomic variables, world oil price assumptions, and assumptions about the severity of weather. Macroeconomic estimates are produced by DRI/McGraw-Hill but are adjusted by EIA to reflect EIA assumptions about the world price of crude oil, energy product prices, and other assumptions which may affect the macroeconomic outlook. The EIA model is available on computer tape from the National Technical Information Service

Damage and recovery of historic buildings: The experience of L’Aquila

International Nuclear Information System (INIS)

Modena, Claudio; Valluzzi, Maria Rosa; Da Porto, Franca; Munari, Marco

2015-01-01

Problems range from the same definition and choice of the “conventional” safety level, to the methodologies that can be used to perform reliable structural analyses and safety verifications (as modern ones are frequently not suitable for the construction under consideration) and to the selection, design and execution of appropriate materials and interventions techniques aimed to repair and strengthen the built heritage while preserving its cultural, historic, artistic values. The earthquake that struck the Abruzzo region on 6. April 2009 at 3:32 a.m., had its epicentre in the capital of the region, L’Aquila, and seriously affected a wide area around the city, where many historic towns and villages are found. Lessons learned from this event gave relevant contributions to develop specific tools, to appropriately tackle the above mentioned problems, available to practitioner engineers and architects: methodology to intervene on complex and connected buildings in the historic centres, definition of adequate materials and techniques to intervene on the damaged buildings, codes and codes of practice specific for historic constructions. A short review of all the mentioned aspects is presented in the paper, making specific reference to research activities, practical applications and to the recent evolution of codes and guidelines [it

The oath of Hippocrates: an historical review.

Science.gov (United States)

Davey, L M

2001-09-01

This presentation is designed to share with fellow neurosurgeons a topic, namely the oath of Hippocrates, that has been a subject of fascination to physicians, scholars, historians, and even the public for the past 2500 years. Its moral and ethical message has exhibited remarkable resiliency through the ages, in varied cultures. Although its language may appear odd, its precepts are as valid today as they were in Hippocrates' time. This can be best understood through an historical review of the oath's transmission and acceptance in different eras of western history. The longevity of the oath, however, is clearly attributable to its intrinsic merit, its high moral reverent tone, and a literary eloquence that placed Hippocrates among the best writers of antiquity. Despite the fame of its author, the oath has experienced a life of its own, from relative obscurity during the Dark Ages to reverential study since the Renaissance. Five aspects are considered in this discussion, i.e., 1) oaths in antiquity; 2) a biographical sketch of Hippocrates; 3) the chain of transmission from antiquity to modern times; 4) comments on other oaths, prayers, codes, and credos; and 5) an analysis and some personal views of the oath.

Historical review of the causes of cancer.

Science.gov (United States)

Blackadar, Clarke Brian

2016-02-10

In the early 1900s, numerous seminal publications reported that high rates of cancer occurred in certain occupations. During this period, work with infectious agents produced only meager results which seemed irrelevant to humans. Then in the 1980s ground breaking evidence began to emerge that a variety of viruses also cause cancer in humans. There is now sufficient evidence of carcinogenicity in humans for human T-cell lymphotrophic virus, human immunodeficiency virus, hepatitis B virus, hepatitis C virus, human papillomavirus, Epstein-Barr virus, and human herpes virus 8 according to the International Agency for Research on Cancer (IARC). Many other causes of cancer have also been identified by the IARC, which include: Sunlight, tobacco, pharmaceuticals, hormones, alcohol, parasites, fungi, bacteria, salted fish, wood dust, and herbs. The World Cancer Research Fund and the American Institute for Cancer Research have determined additional causes of cancer, which include beta carotene, red meat, processed meats, low fibre diets, not breast feeding, obesity, increased adult height and sedentary lifestyles. In brief, a historical review of the discoveries of the causes of human cancer is presented with extended discussions of the difficulties encountered in identifying viral causes of cancer.

Short-Term Energy Outlook: Quarterly projections. Fourth quarter 1993

Energy Technology Data Exchange (ETDEWEB)

1993-11-05

The Energy Information Administration (EIA) prepares quarterly, short-term energy supply, demand, and price projections for publication in February, May, August, and November in the Short-Term Energy Outlook (Outlook). An annual supplement analyzes the performance of previous forecasts, compares recent cases with those of other forecasting services, and discusses current topics related to the short-term energy markets. (See Short-Term Energy Outlook Annual Supplement, DOE/EIA-0202.) The forecast period for this issue of the Outlook extends from the fourth quarter of 1993 through the fourth quarter of 1994. Values for the third quarter of 1993, however, are preliminary EIA estimates (for example, some monthly values for petroleum supply and disposition are derived in part from weekly data reported in the Weekly Petroleum Status Report) or are calculated from model simulations using the latest exogenous information available (for example, electricity sales and generation are simulated using actual weather data). The historical energy data are EIA data published in the Monthly Energy Review, Petroleum Supply Monthly, and other EIA publications.

Canadian CANDU plant historical data systems. A review and look to the future

Deverno, M.; De Grosbois, J.; Pothier, H.

1996-01-01

As part of several CANDU Owner's Group (COG) projects, AECL has conducted a review of current approaches and investigated solutions to plant process data collection, management, and use. Emphasis was placed on understanding the existing functionality and uses of plant data systems, their future needs and benefits. The result is a vision of a plant-wide Historical Data System (HDS) providing seamless access to both near real-time and historical data, user tool-kits for data visualization and analysis, and data management of the larger volume of data acquired during the life of a plant. HDS technology is critical to the implementation of technical surveillance and analysis, predictive and preventative maintenance programs, and other efforts necessary to enhance plant safety, availability, production and productivity. HDS technology will lead to higher capability and capacity factors while minimizing operations, maintenance, and administration (OM and A) costs. (author)

The role of short messaging service in supporting the delivery of healthcare: An umbrella systematic review.

Science.gov (United States)

Househ, Mowafa

2016-06-01

Short messaging service (SMS) messages may present a convenient and cost-effective method to support healthcare interventions. This work assesses the effects of short messaging service on various healthcare interventions found in systematic reviews. The search strategy was based on two key concepts: short messaging service and healthcare delivery. The initial search was conducted in December 2012 and was updated in June 2013. Of the 550 identified references, 13 systematic reviews met the inclusion criteria, of which 8 were published in peer-reviewed journals and 5 were retrieved from the Cochrane library. Data analysis shows that low to moderate research evidence exists on the benefits of short messaging service interventions for appointment reminders, promoting health in developing countries and preventive healthcare. In many interventions, however, there were a few studies that were of high quality, and most of the studies were rated from low to moderate quality or had no rating at all. Healthcare organizations, policy makers, or clinicians using short messaging service messages to support healthcare interventions should (1) implement interventions that have been found to work in healthcare settings, (2) continue evaluating short messaging service interventions that have not been adequately assessed, and (3) improve collaboration between various healthcare entities to develop studies targeted at specific populations to evaluate the long-term impact of short messaging service on healthcare outcomes. © The Author(s) 2014.

HHARP: The Historical Hospital Admission Records Project – a review

Full Text Available Hospital records have frequently been used in epidemiological research (Kilgore et al. 2017; Rushton 2016, and in some cases palaeopathological research. However, the availability of data is problematic, with written records requiring considerable time to interpret, digitise and analyse. In 2001, the Historical Hospital Records Project (HHARP began digitising over 140,000 hospital admission records from four hospitals in London and Glasgow, providing researchers with an online data base of hospital records (Figure 1. I review the data available in the HHARP database, as well as make a preliminary analysis of the hospital records from London and Glasgow between c.1852-1921 which illustrates the value of the HHARP database in understanding disease and medical care during this period.

Doocy, Shannon; Daniels, Amy; Dick, Anna; Kirsch, Thomas D

2013-04-16

Introduction. Although rare, tsunamis have the potential to cause considerable loss of life and injury as well as widespread damage to the natural and built environments. The objectives of this review were to describe the impact of tsunamis on human populations in terms of mortality, injury, and displacement and, to the extent possible, identify risk factors associated with these outcomes. This is one of five reviews on the human impact of natural disasters. Methods. Data on the impact of tsunamis were compiled using two methods, a historical review from 1900 to mid 2009 of tsunami events from multiple databases and a systematic literature review to October 2012 of publications. Analysis included descriptive statistics and bivariate tests for associations between tsunami mortality and characteristics using STATA 11. Findings. There were 255,195 deaths (range 252,619-275,784) and 48,462 injuries (range 45,466-51,457) as a result of tsunamis from 1900 to 2009. The majority of deaths (89%) and injuries reported during this time period were attributed to a single event -the 2004 Indian Ocean tsunami. Findings from the systematic literature review indicate that the primary cause of tsunami-related mortality is drowning, and that females, children and the elderly are at increased mortality risk. The few studies that reported on tsunami-related injury suggest that males and young adults are at increased injury-risk. Conclusions. Early warning systems may help mitigate tsunami-related loss of life.

The Energy Information Administration (EIA) prepares the Short-Term Energy Outlook (energy supply, demand, and price projections) monthly. The forecast period for this issue of the Outlook extends from January 1999 through December 2000. Data values for the fourth quarter 1998, however, are preliminary EIA estimates (for example, some monthly values for petroleum supply and disposition are derived in part from weekly data reported in EIA`s Weekly Petroleum Status Report) or are calculated from model simulations that use the latest exogenous information available (for example, electricity sales and generation are simulated by using actual weather data). The historical energy data, compiled in the January 1999 version of the Short-Term Integrated Forecasting System (STIFS) database, are mostly EIA data regularly published in the Monthly Energy Review, Petroleum Supply Monthly, and other EIA publications. Minor discrepancies between the data in these publications and the historical data in this Outlook are due to independent rounding. The STIFS model is driven principally by three sets of assumptions or inputs: estimates of key macroeconomic variables, world oil price assumptions, and assumptions about the severity of weather. Macroeconomic estimates are produced by DRI/McGraw-Hill but are adjusted by EIA to reflect EIA assumptions about the world price of crude oil, energy product prices, and other assumptions which may affect the macroeconomic outlook. By varying the assumptions, alternative cases are produced by using the STIFS model. 28 figs., 19 tabs.

Historical Review of Uncommanded Lateral-Directional Motions at Transonic Conditions

Science.gov (United States)

Chambers, Joseph R.; Hall, Robert M.

2003-01-01

This paper presents the results of a survey of past experiences with uncommanded lateral-directional motions at transonic speeds during specific military aircraft programs. The effort was undertaken to provide qualitative and quantitative information on past airplane programs that might be of use to the participants in the joint NASA/Navy/Air Force Abrupt Wing Stall (AWS) Program. The AWS Program was initiated because of the experiences of the F/A-l8E/F development program, during which unexpected, severe wing-drop motions were encountered by preproduction aircraft at transonic conditions. These motions were judged to be significantly degrading to the primary mission requirements of the aircraft. Although the problem was subsequently solved for the production version of the F/A-l8E/F, a high-level review panel emphasized the poor understanding of such phenomena and issued a strong recommendation to: "Initiate a national research effort to thoroughly and systematically study the wing drop phenomena." A comprehensive, cooperative NASA/Navy/Air Force AWS Program was designed to respond to provide the required technology requirements. As part of the AWS Program, a work element was directed at a historical review of wing-drop experiences in past aircraft development programs at high subsonic and transonic speeds. In particular, information was requested regarding: specific aircraft configurations that exhibited uncommanded motions and the nature of the motions; geometric characteristics of the air- planes; flight conditions involved in occurrences; relevant data, including wind-tunnel, computational, and flight sources; figures of merit used for analyses; and approaches used to alleviate the problem. An attempt was also made to summarize some of the more important lessons learned from past experiences, and to recommend specific research efforts. In addition to providing technical information to assist the AWS research objectives, the study produced fundamental

Short dental implants have been proposed as a simpler, cheaper, and faster alternative for the rehabilitation of atrophic edentulous areas to avoid the disadvantages of surgical techniques for increasing bone volume. This review will compare short implants (4 to 8 mm) to standard implants (larger than 8 mm) in edentulous jaws, evaluating on the basis of marginal bone loss (MBL), survival rate, complications, and prosthesis failure. We will electronically search for randomized controlled trials comparing short dental implants to standard dental implants in the following databases: PubMed, Web of Science, EMBASE, Scopus, the Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov with English language restrictions. We will manually search the reference lists of relevant reviews and the included articles in this review. The following journals will also be searched: European Journal of Oral Implantology, Clinical Oral Implants Research, and Clinical Implant Dentistry and Related Research. Two reviewers will independently perform the study selection, data extraction and quality assessment (using the Cochrane Collaboration tool) of included studies. All meta-analysis procedures including appropriate effect size combination, sub-group analysis, meta-regression, assessing publication or reporting bias will be performed using Stata (Statacorp, TEXAS) version 12.1. Short implant effectiveness will be assessed using the mean difference of MBL in terms of weighted mean difference (WMD) and standardized mean difference (SMD) using Cohen's method. The combined effect size measures in addition to the related 95% confidence intervals will be estimated by a fixed effect model. The heterogeneity of the related effect size will be assessed using a Q Cochrane test and I2 measure. The MBL will be presented by a standardized mean difference with a 95% confidence interval. The survival rate of implants, prostheses failures, and complications will be reported using a risk

Historical review of long-term soil sampling for environmental surveillance at the Hanford Site and vicinity

Price, K.R.; Rickard, W.H.

1997-08-01

Soil samples have been collected routinely from the environs of the Hanford Site and analyzed since 1971. Correct interpretation of results depends on samples being collected from the same locations, the locations remaining relatively undisturbed, and collection and analytical procedures remaining the same or being equivalent. Historical files, documents, and annual environmental reports were reviewed to evaluate these factors. It was determined that 20 soil sampling locations, 11 onsite and 9 offsite, were established between 1971 and 1977 and represent long-term sampling locations. Sample collection and analytical procedures have remained essentially the same since 1971. The physical ecological attributes of each long-term soil sampling location were evaluated. During the review of historical records, a few results for 1970, 1971, and 1972 were noted as previously unreported in annual or special reports. These results are included in Appendix A. To complete the record, results previously reported in annual environmental reports are given in Appendix B. Global Positioning System (GPS) reading for 20 long-term soil sampling locations are provided in Appendix C.

2018-02-25

A newly-recommended method for restoring large cavities is the biomimetic approach of using short fiber-reinforced composite (SFRC) as dentine-replacing material. The aim of the current review was to present an overview of SFRC and to give the clinician a detailed understanding of this new material and treatment strategy based on available-literature review. A thorough literature search was done up to December 2017. The range of relevant publications was surveyed using PubMed and Google Scholar. From the search results, articles related to our search terms were only considered. The search terms used were "short fiber-reinforced composite", "everX posterior", and "fiber-reinforced composite restorations". Of the assessed articles selected (N = 70), most were laboratory-based research with various test specimen designs prepared according to the ISO standard or with extracted teeth; only four articles were clinical reports. A common finding was that by combining the SFRC as a bulk base with conventional composite, the load-bearing capacity and failure mode of the material combination were improved, as compared to plain conventional composite restoration. In the reviewed studies, the biomimetic restoration technique of using SFRC showed promising characteristics, and therefore, might be recommended as an alternative treatment option for large cavities. © 2018 John Wiley & Sons Australia, Ltd.

The presentations at the short course that were the basis of the present Proceedings covered many critical issues related to the objective of eliminating nuclear weapons as a means of ensuring global security and stability. This paper is based on the concluding talk, which briefly reviewed the course, offered a net assessment of where the project of elimination - a policy objective for nearly all the world's states - stands, and discussed some of the factors that need to be dealt with in achieving a nuclear weapon free world. These include understanding what 'proliferation' means and how it has changed over time, how the spread of nuclear weapons has proceeded over time, both 'vertical' in numbers and 'horizontal' to additional countries, what way the 'vector' of reversing proliferation is pointing, and the roles of nuclear energy and international governance.

Although spacecraft developers have been moving towards standardized product lines as the aerospace industry has matured, NASA's continual need to push the cutting edge of science to accomplish unique, challenging missions can still lead to spacecraft resource growth over time. This paper assesses historical mass, power, cost, and schedule growth for multiple NASA spacecraft from the last twenty years and compares to industry reserve guidelines to understand where the guidelines may fall short. Growth is assessed from project start to launch, from the time of the preliminary design review (PDR) to launch and from the time of the critical design review (CDR) to launch. Data is also assessed not just at the spacecraft bus level, but also at the subsystem level wherever possible, to help obtain further insight into possible drivers of growth. Potential recommendations to minimize spacecraft mass, power, cost, and schedule growth for future missions are also discussed.

Historical Experiments and Physics Teaching: adding considerations from a Bibliographic Review and the Cultural History of Science

Science.gov (United States)

Jardim, W. T.; Guerra, A.

2017-12-01

In this paper, a discussion about the purposes of historical experiments in science teaching found in the literature will be presented. As a starting point, we carried out a bibliographic review, on the websites of six relevant periodicals for the area of Science Teaching and, especially for Physics Teaching. The search was based, at first, on works published between the years 2001 and 2016, from terms like "historical experiments", "museums" and "experience". Thereon, due to the large number of publications found, a screening process was developed based on the analysis of titles, abstracts, keywords and, whether necessary, the whole text, aiming to identify which searches emphasize working with historical experiments in Physics teaching, from a theoretical perspective or based on manipulation of a replica of historical apparatus. The selected proposals were arranged in categories adapted from the work of Heering and Höttecke (2014) which allowed us to draw a parallel between the national and international publication that presented resembling scopes. Furthermore, the analysis of the results leads us to infer that, in general, extralab factors, inherent to science, when not neglected, are placed in a peripheral perspective. Thus, we draw theoretical considerations based on Historians of Science, which develop their researches based on the bias of the Cultural History of Science, seeking to add reflections to what has been developed about historical experiments in teaching up to now.

Review on Electrodynamic Energy Harvesters—A Classification Approach

Directory of Open Access Journals (Sweden)

Roland Lausecker

2013-04-01

Full Text Available Beginning with a short historical sketch, electrodynamic energy harvesters with focus on vibration generators and volumes below 1dm3 are reviewed. The current challenges to generate up to several milliwatts of power from practically relevant flows and vibrations are addressed, and the variety of available solutions is sketched. Sixty-seven different harvester concepts from more than 130 publications are classified with respect to excitation, additional boundary conditions, design and fabrication. A chronological list of the harvester concepts with corresponding references provides an impression about the developments. Besides resonant harvester concepts, the review includes broadband approaches and mechanisms to harvest from flow. Finally, a short overview of harvesters in applications and first market ready concepts is given.

Short dental implants: A scoping review of the literature for patients with head and neck cancer.

Science.gov (United States)

Edher, Faraj; Nguyen, Caroline T

2017-09-16

Dental implants can be essential in the rehabilitation of various cancer defects, but their ideal placement can be complicated by the limited dimensions of the available host bone. Surgical interventions developed to increase the amount of bone are not all predictable or successful and can sometimes be contraindicated. Short dental implants have been suggested as an alternative option in sites where longer implants are not possible. Whether they provide a successful treatment option is unclear. The purpose of this study was to review the literature on short dental implants and assess whether they are a viable definitive treatment option for rehabilitating cancer patients with deficient bone. A scoping review of the literature was performed, including a search of established periodontal textbooks for articles on short dental implants combined with a search of PubMed, MEDLINE, EMBASE, Web of Science, and Cochrane Database of Systematic Reviews. A search for all literature published before June 2016 was based on the following keywords: ['dental implants' OR 'dental implantation, endosseous' OR 'dental prosthesis, implant supported'] AND [short]. The minimum acceptable implant length has been considered to be 6 mm. The survival rates of short implants varied between 74% and 96% at 5 years, depending on factors such as the quality of the patient's bone, primary stability of the implant, clinician's learning curve, and implant surface. Short implants can achieve results similar to those of longer implants in augmented bone and offer a treatment alternative that could reduce the need for invasive surgery and associated morbidity and be safer and more economical. Short dental implants (6 mm to 8 mm) can be used successfully to support single or multiple fixed reconstructions or overdentures in atrophic maxillae and mandibles. The use of short dental implants lessens the need for advanced and complicated surgical bone augmentation procedures, which reduces complications

This paper makes a brief review on 30 years of history of the wind power short-term prediction, since the first ideas and sketches on the theme to the actual state of the art on models and tools, giving emphasis to the most significant proposals and developments. 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 the same in order to compare two models (this fact makes it almost impossible to carry out a quantitative comparison between a huge number of models and methods). In place of a quantitative description, a qualitative approach is preferred for this review, remarking the contribution (and innovative aspect) of each model. On the basis of the review, some topics for future research are pointed out. (author)

Historical Review of Uncommanded Lateral-Directional Motions At Transonic Conditions (Invited)

Science.gov (United States)

Chambers, Joseph R.; Hall, Robert M.

2003-01-01

This paper presents the results of a survey of past experiences with uncommanded lateral-directional motions at transonic speeds during specific military aircraft programs. The effort was undertaken to provide qualitative and quantitative information on past airplane programs that might be of use to the participants in the joint NASA/Navy/Air Force Abrupt Wing Stall (AWS) Program. The AWS Program was initiated because of the experiences of the F/A-18E/F development program, during which unexpected, severe wing-drop motions were encountered by preproduction aircraft at transonic conditions. These motions were judged to be significantly degrading to the primary mission requirements of the aircraft. Although the problem was subsequently solved for the production version of the F/A-l8E/F, a high-level review panel emphasized the poor understanding of such phenomena and issued a strong recommendation to: Initiate a national research effort to thoroughly and systematically study the wing drop phenomena. A comprehensive, cooperative NASA/Navy/Air Force AWS Program was designed to respond to provide the required technology requirements. As part of the AWS Program, a work element was directed at a historical review of wing-drop experiences in past aircraft development programs at high subsonic and transonic speeds. In particular, information was requested regarding: specific aircraft configurations that exhibited uncommanded motions and the nature of the motions; geometric characteristics of the air- planes; flight conditions involved in occurrences; relevant data, including wind-tunnel, computational, and flight sources; figures of merit used for analyses; and approaches used to alleviate the problem. An attempt was also made to summarize some of the more important lessons learned from past experiences, and to recommend specific research efforts. In addition to providing technical information to assist the AWS research objectives, the study produced fundamental information

Distortions Imposed By Inflation on Historical-Cost Depreciation

OpenAIRE

Bravo-Ureta, Boris E.

1983-01-01

The use of historical-cost depreciation in periods of persistent inflation decreases the present value of depreciation deductions, thus understating the true economic cost of capital and increasing the real after-tax rate of return required by potential investors. Efforts to correct these problems by adopting depreciation methods that allow for artificially short recovery periods or accelerated rates do not provide an adequate solution. Distortions imposed by inflation on historical-cost depr...

Management of supraventricular tachycardia using the Valsalva manoeuvre: a historical review and summary of published evidence.

Science.gov (United States)

Smith, Gavin

2012-12-01

Use of the Valsalva manoeuvre (VM) as a first-line management tool for the reversion of supraventricular tachycardia (SVT) in both emergency medicine and prehospital emergency-care settings has presented challenges, requiring continuous examination and refinement to define both its appropriateness and effectiveness. This report details the evolution of knowledge related to SVT and the historical evolution and controversies associated with VM; it also highlights the ongoing development of an evidence-based model of practice for the management of SVT in the emergency medicine and prehospital emergency-care settings. A two-part review of the literature using electronic medical databases was conducted. Other relevant texts or articles unavailable within the electronic search were also identified. Part 1 of the search criteria identified the historical evolution of the pathophysiology of SVT, whereas part 2 identified the use of VM for the clinical management of SVT. Part 1 of the review identified a total of 38 articles with eight meeting the inclusion criteria, and part 2 of the review identified a total of 44 articles with 17 meeting the inclusion criteria. An evidence-based model of practice requires clarification. The differentiation of nodal re-entrant tachycardias may, with further research, lead to identification of the specificity of VM in reversion of SVT during the early stages of arrhythmia. There is a need for further prehospital and emergency department research to quantify an evidence-based approach to VM.

Systems and complexity thinking in the general practice literature: an integrative, historical narrative review.

Sturmberg, Joachim P; Martin, Carmel M; Katerndahl, David A

2014-01-01

Over the past 7 decades, theories in the systems and complexity sciences have had a major influence on academic thinking and research. We assessed the impact of complexity science on general practice/family medicine. We performed a historical integrative review using the following systematic search strategy: medical subject heading [humans] combined in turn with the terms complex adaptive systems, nonlinear dynamics, systems biology, and systems theory, limited to general practice/family medicine and published before December 2010. A total of 16,242 articles were retrieved, of which 49 were published in general practice/family medicine journals. Hand searches and snowballing retrieved another 35. After a full-text review, we included 56 articles dealing specifically with systems sciences and general/family practice. General practice/family medicine engaged with the emerging systems and complexity theories in 4 stages. Before 1995, articles tended to explore common phenomenologic general practice/family medicine experiences. Between 1995 and 2000, articles described the complex adaptive nature of this discipline. Those published between 2000 and 2005 focused on describing the system dynamics of medical practice. After 2005, articles increasingly applied the breadth of complex science theories to health care, health care reform, and the future of medicine. This historical review describes the development of general practice/family medicine in relation to complex adaptive systems theories, and shows how systems sciences more accurately reflect the discipline's philosophy and identity. Analysis suggests that general practice/family medicine first embraced systems theories through conscious reorganization of its boundaries and scope, before applying empirical tools. Future research should concentrate on applying nonlinear dynamics and empirical modeling to patient care, and to organizing and developing local practices, engaging in community development, and influencing

Hypervitaminosis A-induced premature closure of epiphyses (physeal obliteration) in humans and calves (hyena disease): a historical review of the human and veterinary literature

International Nuclear Information System (INIS)

Rothenberg, Alexis B.; Berdon, Walter E.; Woodard, J.C.; Cowles, Robert A.

2007-01-01

Vitamin A toxicity in the infant, which now occurs rarely from dietary overdosage, was recognized in the 1940s as painful periostitis with rare progression to premature closure of the lower limb epiphyses. Decades later, most cases of vitamin A-induced premature epiphyseal closure (physeal obliteration) occur in pediatric dermatologic patients given vitamin A analogues. This phenomenon resembles a strange disease discovered in more recent years in calves with closed epiphyses of the hind limbs, known as hyena disease. This was a mystery until proved to be caused by vitamin A toxicity from enriched grain that causes the calves to have short hind limbs that resemble those of a hyena and gait disturbance. This historical review links the human and veterinary literature in terms of vitamin A-induced epiphyseal closure using a case report format of a 16-month-old human infant with closed knee epiphyses and gait disturbance that is reminiscent of hyena disease seen in calves.

Short-term energy outlook. Quarterly projections, 2nd quarter 1994

Energy Technology Data Exchange (ETDEWEB)

1994-05-01

The Energy Information Administration (EIA) prepares quarterly, short-term energy supply, demand, and price projections for publication in February, May, August, and November in the Short-Term Energy Outlook (Outlook). An annual supplement analyzes the performance of previous forecasts, compares recent cases with those of other forecasting services, and discusses current topics related to the short-term energy markets. The forecast period for this issue of the Outlook extends from the second quarter of 1994 through the fourth quarter of 1995. Values for the first quarter of 1994, however, are preliminary EIA estimates (for example, some monthly values for petroleum supply and disposition are derived in part from weekly data reported in the Weekly Petroleum Status Report) or are calculated from model simulations using the latest exogenous information available. The historical energy data, compiled into the second quarter 1994 version of the Short-Term Integrated Forecasting System (STIFS) database, are mostly EIA data regularly published in the Monthly Energy Review, Petroleum Supply Monthly, and other EIA publications. Minor discrepancies between the data in these publications and the historical data in this Outlook are due to independent rounding. The STIFS database is archived quarterly and is available from the National Technical Information Service. The cases are produced using the STIFS. The STIFS model is driven principally by three sets of assumptions or inputs: estimates of key macroeconomic variables, world oil price assumptions, and assumptions about the severity of weather. Macroeconomic estimates are produced by DRI/McGraw-Hill but are adjusted by EIA to reflect EIA assumptions about the world price of crude oil, energy product prices, and other assumptions which may affect the macroeconomic outlook. The EIA model is available on computer tape from the National Technical Information Service.

The human impact of volcanoes: a historical review of events 1900-2009 and systematic literature review.

Science.gov (United States)

Doocy, Shannon; Daniels, Amy; Dooling, Shayna; Gorokhovich, Yuri

2013-04-16

Introduction. More than 500 million people live within the potential exposure range of a volcano. The risk of catastrophic losses in future eruptions is significant given population growth, proximities of major cities to volcanoes, and the possibility of larger eruptions. The objectives of this review are to describe the impact of volcanoes on the human population, in terms of mortality, injury, and displacement and, to the extent possible, identify risk factors associated with these outcomes. This is one of five reviews on the human impact of natural disasters. Methods. Data on the impact of volcanoes were compiled using two methods, a historical review of volcano events from 1900 to 2009 from multiple databases and a systematic literature review of publications ending in October 2012. Analysis included descriptive statistics and bivariate tests for associations between volcano mortality and characteristics using STATA 11. Findings. There were a total of 91,789 deaths (range: 81,703-102,372), 14,068 injuries (range 11,541-17,922), and 4.72 million people affected by volcanic events between 1900 and 2008. Inconsistent reporting suggests this is an underestimate, particularly in terms of numbers injured and affected. The primary causes of mortality in recent volcanic eruptions were ash asphyxiation, thermal injuries from pyroclastic flow, and trauma. Mortality was concentrated with the ten deadliest eruptions accounting for more than 80% of deaths; 84% of fatalities occurred in four locations (the Island of Martinique (France), Colombia, Indonesia, and Guatemala). Conclusions. Changes in land use practices and population growth provide a background for increasing risk; in conjunction with increasing urbanization in at risk areas, this poses a challenge for future volcano preparedness and mitigation efforts.

Mobile depth profiling and sub-surface imaging techniques for historical paintings—A review

International Nuclear Information System (INIS)

Alfeld, Matthias; Broekaert, José A.C.

2013-01-01

Hidden, sub-surface paint layers and features contain valuable information for the art-historical investigation of a painting's past and for its conservation for coming generations. The number of techniques available for the study of these features has been considerably extended in the last decades and established techniques have been refined. This review focuses on mobile non-destructive subsurface imaging and depth profiling techniques, which allow for the in-situ investigation of easel paintings, i.e. paintings on a portable support. Among the techniques discussed are: X-ray radiography and infrared reflectography, which are long established methods and are in use for several decades. Their capabilities of element/species specific imaging have been extended by the introduction of energy/wavelength resolved measurements. Scanning macro-X-ray fluorescence analysis made it for the first time possible to acquire elemental distribution images in-situ and optical coherence tomography allows for the non-destructive study the surface paint layers in virtual cross-sections. These techniques and their variants are presented next to other techniques, such as Terahertz imaging, Nuclear Magnetic Resonance depth profiling and established techniques for non destructive testing (thermography, ultrasonic imaging and laser based interference methods) applied in the conservation of historical paintings. Next to selected case studies the capabilities and limitations of the techniques are discussed. - Highlights: • All mobile sub-surface and depth-profiling techniques for paintings are reviewed. • The number of techniques available has increased considerably in the last years. • X-ray radiography and infrared reflectography are still the most used techniques. • Scanning macro-XRF and optical coherence tomography begin to establish. • Industrial non destructive testing techniques support the preservation of paintings

Contributions to a historical review of biological anthropology in Brazil from the second half of the twentieth century

Directory of Open Access Journals (Sweden)

Verlan Valle Gaspar Neto

Full Text Available Abstract This article provides a preliminary historical survey of Brazilian biological anthropology from the second half of the twentieth century. Even today, little historiographic information on the last 50 or 60 years is available and/or has been explored, while few allusions to bioanthropology can be found in existing works on the history and contemporary state of anthropology in Brazil; this article attempts to span this gap. The first section examines various aspects of the general development of biological anthropology as it radiated from the centers (Europe and the United States outward over time. This initial survey affords a clearer understanding of the Brazilian case, which is the topic of the second section. This is followed by a brief historical and bibliographic account of the most recent state of biological anthropology in the country, including a number of specialized areas of research. The article concludes with a short discussion of the material covered.

Pipework failures - a review of historical incidents

International Nuclear Information System (INIS)

Blything, K.W.; Parry, S.T.

1988-01-01

A description is presented of the gathering of historical pipework incident data and its analysis to determine the causes and underlying reasons for failure. The following terms of reference were agreed: (a) To review data on failures associated with pipework to establish the principal causes of failure. This should include not only rupture of the pipe itself, but also pipework induced failures, such as severe flange leaks and excessive strains resulting in failure of connected equipment. (b) To suggest an incident classification for pipework systems which will alert design, construction, maintenance, and operating personnel to the need for special care. (c) To advise non-piping specialists of the type of situation which could result in failure if not allowed for in the design, e.g. dynamic and transient conditions. (d) To recommend, possibly as the result of (a) above, areas where present procedures and codes of practice may require amplification. Brief descriptions are given of selected incidents where the consequences are considered to be serious in terms of damage and financial loss. For consequence analysis, the release rate is an important parameter and, where possible, the proportion of incidents in the failure mode categories, leaks, ''ruptures/severances'' are given. Although not one of the agreed objectives, the determination of failure rates was recognised as an important requirement in the risk assessment of pipework systems. The quality of data gathered however was found to be inadequate for any statistical analysis and no failure rate values are given in this report. (author)

Historical earthquake investigations in Greece

Directory of Open Access Journals (Sweden)

K. Makropoulos

2004-06-01

Full Text Available The active tectonics of the area of Greece and its seismic activity have always been present in the country?s history. Many researchers, tempted to work on Greek historical earthquakes, have realized that this is a task not easily fulfilled. The existing catalogues of strong historical earthquakes are useful tools to perform general SHA studies. However, a variety of supporting datasets, non-uniformly distributed in space and time, need to be further investigated. In the present paper, a review of historical earthquake studies in Greece is attempted. The seismic history of the country is divided into four main periods. In each one of them, characteristic examples, studies and approaches are presented.

Compton scatter imaging: A tool for historical exploration

International Nuclear Information System (INIS)

Harding, G.; Harding, E.

2010-01-01

This review discusses the principles and technological realisation of a technique, termed Compton scatter imaging (CSI), which is based on spatially resolved detection of Compton scattered X-rays. The applicational focus of this review is to objects of historical interest. Following a historical survey of CSI, a description is given of the major characteristics of Compton X-ray scatter. In particular back-scattered X-rays allow massive objects to be imaged, which would otherwise be too absorbing for the conventional transmission X-ray technique. The ComScan (an acronym for Compton scatter scanner) is a commercially available backscatter imaging system, which is discussed here in some detail. ComScan images from some artefacts of historical interest, namely a fresco, an Egyptian mummy and a mediaeval clasp are presented and their use in historical analysis is indicated. The utility of scientific and technical advance for not only exploring history, but also restoring it, is briefly discussed.

Short- and long-term impact of critical illness on relatives: literature review.

Science.gov (United States)

Paul, Fiona; Rattray, Janice

2008-05-01

This paper is a report of a literature review undertaken to identify the short- and long-term impact of critical illness on relatives. Patients in intensive care can experience physical and psychological consequences, and their relatives may also experience such effects. Although it is recognized that relatives have specific needs, it is not clear whether these needs are always met and whether further support is required, particularly after intensive care. The following databases were searched for the period 1950-2007: Medline, British Nursing Index and Archive, EMBASE, CINAHL, PsycINFO and EMB Reviews--Cochrane Central Register of Clinical Trials. Search terms focused on adult relatives of critically ill adult patients during and after intensive care. Recurrent topics were categorized to structure the review, i.e. 'relatives needs', 'meeting relatives' needs', 'interventions', 'satisfaction', 'psychological outcomes' and 'coping'. Studies have mainly identified relatives' immediate needs using the Critical Care Family Needs Inventory. There are few studies of interventions to meet relatives' needs and the short- and long-term effects of critical illness on relatives. Despite widespread use of the Critical Care Family Needs Inventory, factors such as local or cultural differences may influence relatives' needs. Relatives may also have unidentified needs, and these needs should be explored. Limited research has been carried out into interventions to meet relatives' needs and the effects of critical illness on their well-being, yet some relatives may experience negative psychological consequences far beyond the acute phase of the illness.

Seddon, E. A.; Clarke, J. A.; Dunning, D. J.; Masciovecchio, C.; Milne, C. J.; Parmigiani, F.; Rugg, D.; Spence, J. C. H.; Thompson, N. R.; Ueda, K.; Vinko, S. M.; Wark, J. S.; Wurth, W.

2017-11-01

This review is focused on free-electron lasers (FELs) in the hard to soft x-ray regime. The aim is to provide newcomers to the area with insights into: the basic physics of FELs, the qualities of the radiation they produce, the challenges of transmitting that radiation to end users and the diversity of current scientific applications. Initial consideration is given to FEL theory in order to provide the foundation for discussion of FEL output properties and the technical challenges of short-wavelength FELs. This is followed by an overview of existing x-ray FEL facilities, future facilities and FEL frontiers. To provide a context for information in the above sections, a detailed comparison of the photon pulse characteristics of FEL sources with those of other sources of high brightness x-rays is made. A brief summary of FEL beamline design and photon diagnostics then precedes an overview of FEL scientific applications. Recent highlights are covered in sections on structural biology, atomic and molecular physics, photochemistry, non-linear spectroscopy, shock physics, solid density plasmas. A short industrial perspective is also included to emphasise potential in this area. Dedicated to John M J Madey (1943-2016) and Rodolfo Bonifacio (1940-2016) whose perception, drive and perseverance paved the way for the realisation and development of short-wavelength free-electron lasers.

Effects of external focus of attention on balance: a short review.

Science.gov (United States)

Park, Sun Hee; Yi, Chae Woo; Shin, Ju Yong; Ryu, Young Uk

2015-12-01

[Purpose] The present study reviewed studies that examined the effects of attentional focus on balance. [Methods] Keywords such as "attentional", "focus", and "balance" were used to find relevant research papers in PubMed (www.ncbi.nlm.nih.gov/pubmed). Forty-five papers were found, and 18 of them were used for this study, excluding review papers and papers irrelevant to the topic of this study. [Results] Among the papers used for the review, the number of papers in which external focus produced effective outcomes was 15 (83.3%). The number of papers in which both external and internal focus produced effective outcomes was 2 (11.1%). The number of paper in which no instruction about attentional focus was effective was 1 (5.5%), and the number of papers in which internal focus was effective was zero. [Conclusion] This short review suggests clinical implications about how physical therapists can use attentional focus for balance rehabilitation of patients. Instructions about external focus of attention can generally be useful as a method to improve posture and balance control. Furthermore, the present reviews indicates that external focus of attention would be more useful in a rehabilitation stage in which the difficulty level of balance performance is gradually increased.

Piezoelectric Transformers: An Historical Review

Directory of Open Access Journals (Sweden)

Alfredo Vazquez Carazo

2016-04-01

Full Text Available Piezoelectric transformers (PTs are solid-state devices that transform electrical energy into electrical energy by means of a mechanical vibration. These devices are manufactured using piezoelectric materials that are driven at resonance. With appropriate design and circuitry, it is possible to step up and step down the voltages between the input and output sections of the piezoelectric transformer, without making use of magnetic materials and obtaining excellent conversion efficiencies. The initial concept of a piezoelectric ceramic transformer was proposed by Charles A. Rosen in 1954. Since then, the evolution of piezoelectric transformers through history has been linked to the relevant work of some excellent researchers as well as to the evolution in materials, manufacturing processes, and driving circuit techniques. This paper summarizes the historical evolution of the technology.

Insect Pests and Integrated Pest Management in Museums, Libraries and Historic Buildings.

Science.gov (United States)

Querner, Pascal

2015-06-16

Insect pests are responsible for substantial damage to museum objects, historic books and in buildings like palaces or historic houses. Different wood boring beetles (Anobium punctatum, Hylotrupes bajulus, Lyctus sp. or introduced species), the biscuit beetle (Stegobium paniceum), the cigarette beetle (Lasioderma serricorne), different Dermestides (Attagenus sp., Anthrenus sp., Dermestes sp., Trogoderma sp.), moths like the webbing clothes moth (Tineola bisselliella), Silverfish (Lepisma saccharina) and booklice (Psocoptera) can damage materials, objects or building parts. They are the most common pests found in collections in central Europe, but most of them are distributed all over the world. In tropical countries, termites, cockroaches and other insect pests are also found and result in even higher damage of wood and paper or are a commune annoyance in buildings. In this short review, an introduction to Integrated Pest Management (IPM) in museums is given, the most valuable collections, preventive measures, monitoring in museums, staff responsible for the IPM and chemical free treatment methods are described. In the second part of the paper, the most important insect pests occurring in museums, archives, libraries and historic buildings in central Europe are discussed with a description of the materials and object types that are mostly infested and damaged. Some information on their phenology and biology are highlighted as they can be used in the IPM concept against them.

The novel as short story

Directory of Open Access Journals (Sweden)

Kirk Schlueter

2013-06-01

Full Text Available In recent history, the novel has been thought of and defined primarily as a long prose narrative. However, this has not been the case historically, as the original meaning of "novel" was for "a piece of news" or "a short story or novella." Returning to this original definition, I propose a new way of viewing the work known contemporarily as the novel as a collection, or sequence, of united short stories rather than a single indivisible work, with the component short stories or novellas comprising the sequence renamed as "novels." A brief examination of several classic works traditionally considered novels serves to illustrate how this change in definition will affect reading.

ENVIRONMENTAL REVIEWS AND CASE STUDIES: Addressing the Public Outreach Responsibilities of the National Historic Preservation Act: Argonne National Laboratory’s Box Digital Display Platform

Energy Technology Data Exchange (ETDEWEB)

O’Rourke, Daniel J.; Weber, Cory C.; Richmond, Pamela D.

2016-07-29

Federal agencies are made responsible for managing the historic properties under their jurisdiction by the National Historic Preservation Act of 1966, as amended. A component of this responsibility is to mitigate the effect of a federal undertaking on historic properties through mitigation often through documentation. Providing public access to this documentation has always been a challenge. To address the issue of public access to mitigation information, personnel from Argonne National Laboratory created the Box Digital Display Platform, a system for communicating information about historic properties to the public. The platform, developed for the US Army Dugway Proving Ground, uses short introductory videos to present a topic but can also incorporate photos, drawings, GIS information, and documents. The system operates from a small, self-contained computer that can be attached to any digital monitor via an HDMI cable. The system relies on web-based software that allows the information to be republished as a touch-screen device application or as a website. The system does not connect to the Internet, and this increases security and eliminates the software maintenance fees associated with websites. The platform is designed to incorporate the products of past documentation to make this information more accessible to the public; specifically those documentations developed using the Historic American Building Survey/ Historic American Engineering Record (HABS/HAER) standards. Argonne National Laboratory’s Box Digital Display Platform can assist federal agencies in complying with the requirements of the National Historic Preservation Act.

Short-term energy outlook, April 1999

Energy Technology Data Exchange (ETDEWEB)

NONE

1999-04-01

The forecast period for this issue of the Outlook extends from April 1999 through December 2000. Data values for the first quarter 1999, however, are preliminary EIA estimates (for example, some monthly values for petroleum supply and disposition are derived in part from weekly data reported in EIA`s Weekly Petroleum Status Report) or are calculated from model simulations that use the latest exogenous information available (for example, electricity sales and generation are simulated by using actual weather data). The historical energy data, compiled in the April 1999 version of the Short-Term Integrated forecasting system (STIFS) database, are mostly EIA data regularly published in the Monthly Energy Review, Petroleum Supply Monthly, and other EIA publications. Minor discrepancies between the data in these publications and the historical data in this Outlook are due to independent rounding. The STIFS model is driven principally by three sets of assumptions or inputs: estimates of key macroeconomic variables, world oil price assumptions, and assumptions about the severity of weather. Macroeconomic estimates are produced by DRI/McGraw-Hill but are adjusted by EIA to reflect EIA assumptions about the world price of crude oil, energy product prices, and other assumptions which may affect the macroeconomic outlook. By varying the assumptions, alternative cases are produced by using the STIFS model. 25 figs., 19 tabs.

2016-04-01

This article presents a historical review of the performance of 23 cesarean sections at the King’s Maternity Hospital and Midwifery School in Zagreb during the 1908-1918 period. Following prenatal screening by midwives and doctors in the hospital, deliveries in high risk pregnant women were performed at maternity hospitals, not at home. The most common indication for cesarean section was narrowed pelvis in 65.2% of women, while postpartum febrile condition was the most common complication in the puerperium. Maternal mortality due to sepsis after the procedure was 8.69% and overall perinatal mortality was 36.3% (stillbirths and early neonatal deaths).

Short dental implants versus standard dental implants placed in the posterior jaws: A systematic review and meta-analysis.

The purpose of the present systematic review and meta-analysis was to compare short implants (equal or less than 8mm) versus standard implants (larger than 8mm) placed in posterior regions of maxilla and mandible, evaluating survival rates of implants, marginal bone loss, complications and prosthesis failures. This review has been registered at PROSPERO under the number CRD42015016588. Main search terms were used in combination: dental implant, short implant, short dental implants, short dental implants posterior, short dental implants maxilla, and short dental implants mandible. An electronic search for data published up until September/2015 was undertaken using the PubMed/Medline, Embase and The Cochrane Library databases. Eligibility criteria included clinical human studies, randomized controlled trials and/or prospective studies, which evaluated short implants in comparison to standard implants in the same study. The search identified 1460 references, after inclusion criteria 13 studies were assessed for eligibility. A total of 1269 patients, who had received a total of 2631 dental implants. The results showed that there was no significant difference of implants survival (P=.24; RR:1.35; CI: 0.82-2.22), marginal bone loss (P=.06; MD: -0.20; CI: -0.41 to 0.00), complications (P=.08; RR:0.54; CI: 0.27-1.09) and prosthesis failures (P=.92; RR:0.96; CI: 0.44-2.09). Short implants are considered a predictable treatment for posterior jaws. However, short implants with length less than 8 mm (4-7 mm) should be used with caution because they present greater risks to failures compared to standard implants. Short implants are frequently placed in the posterior area in order to avoid complementary surgical procedures. However, clinicians need to be aware that short implants with length less than 8mm present greater risk of failures. Copyright © 2016. Published by Elsevier Ltd.

Kanti Bera, Tushar

2018-03-01

Electrical Impedance Tomography (EIT) is a tomographic imaging method which solves an ill posed inverse problem using the boundary voltage-current data collected from the surface of the object under test. Though the spatial resolution is comparatively low compared to conventional tomographic imaging modalities, due to several advantages EIT has been studied for a number of applications such as medical imaging, material engineering, civil engineering, biotechnology, chemical engineering, MEMS and other fields of engineering and applied sciences. In this paper, the applications of EIT have been reviewed and presented as a short summary. The working principal, instrumentation and advantages are briefly discussed followed by a detail discussion on the applications of EIT technology in different areas of engineering, technology and applied sciences.

Caspian sea-level changes during the last millennium: historical and geological evidence from the south Caspian Sea

Historical literature may constitute a valuable source of information to reconstruct sea-level changes. Here, historical documents and geological records have been combined to reconstruct Caspian sea-level (CSL) changes during the last millennium. In addition to a comprehensive literature review, new data from two short sediment cores were obtained from the south-eastern Caspian coast to identify coastal change driven by water-level changes and to compare the results with other geological and historical findings. The overall results indicate a high-stand during the Little Ice Age, up to -21 m (and extra rises due to manmade river avulsion), with a -28 m low-stand during the Medieval Climate Anomaly, while presently the CSL stands at -26.5 m. A comparison of the CSL curve with other lake systems and proxy records suggests that the main sea-level oscillations are essentially paced by solar irradiance. Although the major controller of the long-term CSL changes is driven by climatological factors, the seismicity of the basin creates local changes in base level. These local base-level changes should be considered in any CSL reconstruction.

2010-03-01

The history of treatment for cryptorchidism dates back more than 200 years. This review is intended to highlight some historical aspect that led us to our current surgical treatment of this condition. The medical and historical surgical literatures pertaining to cryptorchidism were reviewed. Data sources were PubMed, Embase, conference proceedings, and bibliographies. No language, date, or publication status restrictions were imposed. The study of cryptorchidism began with the anatomical descriptions of Baron Albrecht von Haller and John Hunter. Attempts at surgical correction of the undescended testis began in the early 1800s, culminating in the first successful orchiopexy by Thomas Annandale in 1877. Max Schüller, Arthur Dean Bevan and Lattimer contributed to the establishment of current techniques for standard orchiopexy. Later, laparoscopy, high inguinal incision (Jones' approach) and scrotal approach were added to the list of current orchiopexy.

Full Text Available Short-range noncontact sensors are capable of remotely detecting the precise movements of the subjects or wirelessly estimating the distance from the sensor to the subject. They find wide applications in our day lives such as noncontact vital sign detection of heart beat and respiration, sleep monitoring, occupancy sensing, and gesture sensing. In recent years, short-range noncontact sensors are attracting more and more efforts from both academia and industry due to their vast applications. Compared to other radar architectures such as pulse radar and frequency-modulated continuous-wave (FMCW radar, Doppler radar is gaining more popularity in terms of system integration and low-power operation. This paper reviews the recent technical advances in Doppler radars for healthcare applications, including system hardware improvement, digital signal processing, and chip integration. This paper also discusses the hybrid FMCW-interferometry radars and the emerging applications and the future trends.

[Empacho: An historical review of popular Chilean childhood disease (1674-2014)].

Science.gov (United States)

Campos Navarro, Roberto

2016-01-01

"Empacho" (abdominal pain and bloating), "mal de ojo" (evil eye), "los aires" (illnesses said to be caught by catching draughts), "el susto" or "espanto" (fright or panic), are the principal and most well-known popular Latin American illnesses. As regards empacho, the medical, historical and ethnographic information is extensive and detailed, since there documents recording it from the 16th century until recent times (2014), and in the case of Chile since 1674. For this review, 109 source documents from libraries in Chile, including some foreign ones, were consulted. It was found that the illness is known all over the country. It is a digestive system disorder caused by over-eating and the ingestion of products difficult to digest or indigestible, which cause problems in gastrointestinal transit. The most significant clinical data are gastralgia, diarrhoea or constipation, vomiting, fever, and other discomforts. The illness is treated at home, and if necessary, popular specialists are employed, with a visit to a qualified doctor being exceptional. There are many complex and combined treatments, which go from herbal products to ritual elements, not forgetting the so-called "quebradura del empacho". This review summary of empacho in Chile should enable the paediatrician to enter the world of popular knowledge and practices with the aim of improving the care of child patients and their families. It should also lead to the serious and systematic study of this nosological condition that will continue to exist in the future. Copyright © 2015 Sociedad Chilena de Pediatría.

The needs of having a paradigm shift from public sector to private sector on funding digitizing management work of historical buildings in Malaysia

Science.gov (United States)

Kamarudin, M. K.; Yahya, Z.; Harun, R.; Jaapar, A.

2014-02-01

In Malaysia, the government agencies that handle the management of historical buildings are finding themselves facing a shortage of funds to provide the necessary work on digitalising management works. Due to the rising cost of management, which also covers maintenance and infrastructure works, there is a need for a paradigm shift from public sector to private sector provision on infrastructure and management works. Therefore the government agencies need to find the suitable mechanism to encourage private sector especially the private property and developers to take part in it. This scenario has encouraged the authorities to look new ways of entering into partnership and collaboration with the private sector to secure the continuity of provision and funding. The paper first reviews the different approach to facilitate off-site local management system of historical buildings and then examines options for both private and public funding in digitalising the historical buildings management works by interviewing government officer, conservator and member of nongovernment agencies. It then explores how the current system of management may adopt the shift to avoid any vulnerability and threat to the existing historical buildings. This paper concludes with a short summary of key issues in management works of historical buildings and recommendations.

Rudhe syndrome: reversible right middle lobe emphysema in infants with left-to-right shunts - an historical review

International Nuclear Information System (INIS)

Collins, Lee K.; Levin, Terry L.; Berdon, Walter E.; Cowles, Robert A.; Newman, Beverley

2010-01-01

In 1971, the Swedish radiologist Ulf Rudhe wrote a provocative paper on right middle lobe emphysema in infants with left-to-right shunts in which he suggested cardiac surgery rather than lung resection. At the time, this was counter to accepted medical practice. Earlier diagnosis and better medical management of ventricular septal defect in infants has proved Rudhe correct. However, two current cases of large left-to-right shunts in infants with emphysema of the right middle lobe prompt this historical review of what seemed a closed-episode in pediatric cardiac surgery.

Spa Treatment (Balneotherapy) for Fibromyalgia—A Qualitative-Narrative Review and a Historical Perspective

Science.gov (United States)

Ablin, Jacob N.; Buskila, Dan

2013-01-01

Aim. To perform a narrative review of spa therapy for management of the fibromyalgia syndrome (FMS), evaluating this traditional time-honored form of therapy in a historical perspective. Methods. Medline was searched using the terms “Spa therapy,” “Balneotherapy,” and “Fibromyalgia” between 1990 (year of ACR fibromyalgia criteria publication) and April 2013. The Cochrane database was also searched. Publications relating to the implementation of spa therapy and related practices over the centuries were identified through references, searched, and reviewed. Results. Reports of balneotherapy were described from diverse locations throughout Europe and Asia, and various forms of water-related therapy have been incorporated for many musculoskeletal indications. In the management of FMS, spa therapy has generally been shown to be well accepted and moderately effective for symptom reduction. Conclusion. While achieving high-quality evidence-based conclusions is difficult for complex natural therapies such as spa therapy, the existing evidence indicates a positive effect in management of FMS. In view of the long history of this modality in the management of rheumatic pain as well as the inherent difficulties related to pharmacological treatment, the role of spa therapy should currently be recognized as part of a therapeutic program for FMS.

Short-term energy outlook, quarterly projections, first quarter 1998

Energy Technology Data Exchange (ETDEWEB)

NONE

1998-01-01

The forecast period for this issue of the Outlook extends from the first quarter of 1998 through the fourth quarter of 1999. Values for the fourth quarter of 1997, however, are preliminary EIA estimates (for example, some monthly values for petroleum supply and disposition are derived in part from weekly data reported in EIA`s Weekly Petroleum Status Report) or are calculated from model simulations that use the latest exogenous information available (for example, electricity sales and generation are simulated by using actual weather data). The historical energy data, compiled in the first quarter 1998 version of the Short-Term Integrated Forecasting System (STIFS) database, are mostly EIA data regularly published in the Monthly Energy Review, Petroleum Supply Monthly, and other EIA publications. Minor discrepancies between the data in these publications and the historical data in this Outlook are due to independent rounding. The STIFS model is driven principally by three sets of assumptions or inputs: estimates of key macroeconomic variables, world oil price assumptions, and assumptions about the severity of weather. Macroeconomic estimates are adjusted by EIA to reflect EIA assumptions which may affect the macroeconomic outlook. By varying the assumptions, alternative cases are produced by using the STIFS model. 24 figs., 19 tabs.

Historic Eastern Canadian earthquakes

International Nuclear Information System (INIS)

Asmis, G.J.K.; Atchinson, R.J.

1981-01-01

Nuclear power plants licensed in Canada have been designed to resist earthquakes: not all plants, however, have been explicitly designed to the same level of earthquake induced forces. Understanding the nature of strong ground motion near the source of the earthquake is still very tentative. This paper reviews historical and scientific accounts of the three strongest earthquakes - St. Lawrence (1925), Temiskaming (1935), Cornwall (1944) - that have occurred in Canada in 'modern' times, field studies of near-field strong ground motion records and their resultant damage or non-damage to industrial facilities, and numerical modelling of earthquake sources and resultant wave propagation to produce accelerograms consistent with the above historical record and field studies. It is concluded that for future construction of NPP's near-field strong motion must be explicitly considered in design

Making a Historical Survey of a State's Nuclear Ambitions. Impact of Historical Developments of a State's National Nuclear Non-Proliferation Policy on Additional Protocol Implementation

International Nuclear Information System (INIS)

Jonter, Thomas

2003-03-01

In 1998, SKI initiated a project to conduct a historical survey of the Swedish nuclear weapons research for the period 1945-1972. IAEA became interested and accepted it in 2000 as a support program task to increase transparency and to support the implementation of the Additional Protocol in Sweden. The main purpose of the Additional Protocol is to make the IAEA control system more efficient with regard to nuclear material, facilities and research. Other countries have now shown interest to follow the Swedish example and to make their own reviews of their past nuclear energy and nuclear weapons research. The most important aim is to produce basic information for IAEA on the nuclear activities of the past and to refine and strengthen the instruments of the Safeguard System within the Additional Protocol. The first objective of this report is to present a short summary of the Swedish historical survey, as well as similar projects in other countries dealing with nuclear-related and nuclear weapons research reviews. These tasks are dealt with in chapter 2. Secondly, the objective is to present a general model of how a national base survey can be designed. The model is based on the Swedish experiences and it has been designed to also serve as a guideline for other countries to strengthen their safeguards systems within the framework of the Additional Protocol. Since other States declared that they would make similar historical surveys, the SKI decided to work out a model that could be used by other countries intending to conduct such studies. Estonia, Latvia and Lithuania are participating in a co-operation project to carry out such nationally base surveys under the auspices of the Swedish Nuclear Power Inspectorate. Finland is also conducting such a survey, but it is done independently, albeit in close exchange of views between SKI and its Finnish counterpart, STUK. This is described in chapter 3. The third objective is to develop a pedagogic methodology for teaching

Mathematical modeling of climate change and malaria transmission dynamics: a historical review.

Science.gov (United States)

Eikenberry, Steffen E; Gumel, Abba B

2018-04-24

Malaria, one of the greatest historical killers of mankind, continues to claim around half a million lives annually, with almost all deaths occurring in children under the age of five living in tropical Africa. The range of this disease is limited by climate to the warmer regions of the globe, and so anthropogenic global warming (and climate change more broadly) now threatens to alter the geographic area for potential malaria transmission, as both the Plasmodium malaria parasite and Anopheles mosquito vector have highly temperature-dependent lifecycles, while the aquatic immature Anopheles habitats are also strongly dependent upon rainfall and local hydrodynamics. A wide variety of process-based (or mechanistic) mathematical models have thus been proposed for the complex, highly nonlinear weather-driven Anopheles lifecycle and malaria transmission dynamics, but have reached somewhat disparate conclusions as to optimum temperatures for transmission, and the possible effect of increasing temperatures upon (potential) malaria distribution, with some projecting a large increase in the area at risk for malaria, but others predicting primarily a shift in the disease's geographic range. More generally, both global and local environmental changes drove the initial emergence of P. falciparum as a major human pathogen in tropical Africa some 10,000 years ago, and the disease has a long and deep history through the present. It is the goal of this paper to review major aspects of malaria biology, methods for formalizing these into mathematical forms, uncertainties and controversies in proper modeling methodology, and to provide a timeline of some major modeling efforts from the classical works of Sir Ronald Ross and George Macdonald through recent climate-focused modeling studies. Finally, we attempt to place such mathematical work within a broader historical context for the "million-murdering Death" of malaria.

1992-07-01

After a historical introduction and some short remarks on criminal arson, this review of the literature since 1955 mainly focuses on pathological firesetting. It deals with all important aspects of the psychiatry of firesetting: arson by persons referred to psychiatric examination, by the mentally ill, and by psychiatric inpatients, the relationship between arson and sexuality, psychoanalytical contributions, arson by children and juveniles, therapy and prevention of firesetting behaviour. Female arsonists, recidivism, and suicide by burning are considered separately.

Short Review on Predicting Fouling in RO Desalination

Directory of Open Access Journals (Sweden)

Alejandro Ruiz-García

2017-10-01

Full Text Available Reverse Osmosis (RO membrane fouling is one of the main challenges that membrane manufactures, the scientific community and industry professionals have to deal with. The consequences of this inevitable phenomenon have a negative effect on the performance of the desalination system. Predicting fouling in RO systems is key to evaluating the long-term operating conditions and costs. Much research has been done on fouling indices, methods, techniques and prediction models to estimate the influence of fouling on the performance of RO systems. This paper offers a short review evaluating the state of industry knowledge in the development of fouling indices and models in membrane systems for desalination in terms of use and applicability. Despite major efforts in this field, there are gaps in terms of effective methods and models for the estimation of fouling in full-scale RO desalination plants. In existing models applied to full-scale RO desalination plants, neither the spacer geometry of membranes, nor the efficiency and frequency of chemical cleanings are considered.

Differential diagnosis of CNS angiostrongyliasis: a short review.

Science.gov (United States)

Senthong, Vichai; Chindaprasirt, Jarin; Sawanyawisuth, Kittisak

2013-06-01

The diagnostic criterion for eosinophilic meningitis (EOM) is the identification of an absolute count of 10 eosinophils per ml or more than 10% of the total white blood cells in the cerebrospinal fluid (CSF) in the proper clinical context. The most common cause of EOM is Angiostrongylus cantonensis infection, termed meningitic angiostrongyliasis (MA). Neurognathostomiasis (NG) is the main parasitic disease in the differential diagnosis of meningitic angiostrongyliasis. This short review is based on articles published on Medline between 2000 and 2012 related to EOM. There are three main approaches that can be used to differentiate between MA and NG, involving clinical factors, history of larval exposure, and serological tests. MA patients presented with acute severe headache but without neurological deficit, combined with a history of eating uncooked snails or slugs. NG patients always presented with motor weakness, migratory swelling, radicular pain and had history of eating uncooked poultry or fish. Specific antigenic bands in immunoblot tests are helpful tools to differentiate the two diseases. Other causes of eosinophilic meningitis are neurocysticercosis, cerebral paragonimiasis, Toxoplasma canis, Baylisascaris, tuberculous meningitis, and cryptococcal meningitis.

Cotugno described the clinical entity of sciatica in 1764. However, the association between sciatica and compression of lumbar nerve roots was not realized until the 1920s. Back surgery for herniated nucleus pulposus then became fashionable, and plain radiography and myelography enabled preoperative mapping. Recently other imaging techniques have emerged, such as computerized tomography and magnetic resonance imaging. This has increased the knowledge of the etiology of lumbar root compressions, and invasive therapies for sciatica have become more diversified. It is easy to lose perspective among the available imaging procedures and therapeutic techniques. The aim of this paper is to present the current status from a historical point of view, with special emphasis on the most common imaging methods for the investigation of lumbosacral radiculopathies. 48 refs., 4 figs.

To identify practices for conducting international short-term medical missions (STMMs) recommended in the literature and examine how these link STMMs to recipient countries' existing health systems. Systematic review of PubMed-indexed articles on STMMs and their bibliographies using preferred reporting items for systematic reviews and meta-analyses guidelines. Recommendations were organized using the World Health Organization Health Systems Framework. In 92 publications, 67 % offered at least one recommendation that would link STMMs to the recipient country's health system. Among these recommendations, most focused on service delivery and few on health financing and governance. There is a lack of consensus around a proper standard of care, patient selection, and trip duration. Comprehensive global standards are needed for STMM work to ensure that services are beneficial both to patients and to the broader healthcare systems of recipient countries. By providing an overview of the current recommendations and important gaps where practice recommendations are needed, this study can provide relevant input into the development of global standards for STMMs.

Kinetic instabilities in the solar wind: A short review

Energy Technology Data Exchange (ETDEWEB)

Matteini, Lorenzo, E-mail: l.matteini@imperial.ac.uk [Imperial College London, London SW7 2AZ (United Kingdom)

2016-03-25

We know from in situ measurements that solar wind plasma is far from thermal equilibrium. Distribution functions of its main constituents -electrons, protons, and alpha particles-show several departures from Maxwellian, including temperature anisotropy, relative drifts and secondary populations streaming along the local magnetic field. We present a short review of recent solar wind observations of these non-thermal features and associated signatures of wave-particle interactions. Several kinetic instabilities are expected to be at work in the solar wind during its expansion, playing a role in the continuous shaping of particle distributions with distance, and regulating the macroscopic behavior of the plasma. Over the past years, modeling of these processes by means of numerical simulations has been successful in reproducing and explaining the observations; these include the evolution of the plasma due to radial expansion and the response of individual species to different kinetic instabilities. Finally, the impact of local inhomogeneities, like current sheets and turbulence, on the development of kinetic instabilities is also discussed.

Review articles on the history of medical topics in recent medical (non-historical) journals are often of a much worse quality than observational and experimental articles. The criteria of quality of a historical review article, elaborated on the example of the contribution. "300 years of intramedullary fixation - from Aztec practice to standard treatment modality" by U. Knothe, M. L. Knothe Tate, and S. M. Perren, are: clear definition of the theme treated, extensive heuristic investigations, exact study of source material and original publications, critical sifting of secondary literature, naming of the first names and biographical data of historical persons, account of the historical background, use of historical evidences, and reviewing by a medical historian. By taking notice of these items historical misjudgements can be avoided.

Integrating probabilistic models of perception and interactive neural networks: a historical and tutorial review.

Science.gov (United States)

McClelland, James L

2013-01-01

This article seeks to establish a rapprochement between explicitly Bayesian models of contextual effects in perception and neural network models of such effects, particularly the connectionist interactive activation (IA) model of perception. The article is in part an historical review and in part a tutorial, reviewing the probabilistic Bayesian approach to understanding perception and how it may be shaped by context, and also reviewing ideas about how such probabilistic computations may be carried out in neural networks, focusing on the role of context in interactive neural networks, in which both bottom-up and top-down signals affect the interpretation of sensory inputs. It is pointed out that connectionist units that use the logistic or softmax activation functions can exactly compute Bayesian posterior probabilities when the bias terms and connection weights affecting such units are set to the logarithms of appropriate probabilistic quantities. Bayesian concepts such the prior, likelihood, (joint and marginal) posterior, probability matching and maximizing, and calculating vs. sampling from the posterior are all reviewed and linked to neural network computations. Probabilistic and neural network models are explicitly linked to the concept of a probabilistic generative model that describes the relationship between the underlying target of perception (e.g., the word intended by a speaker or other source of sensory stimuli) and the sensory input that reaches the perceiver for use in inferring the underlying target. It is shown how a new version of the IA model called the multinomial interactive activation (MIA) model can sample correctly from the joint posterior of a proposed generative model for perception of letters in words, indicating that interactive processing is fully consistent with principled probabilistic computation. Ways in which these computations might be realized in real neural systems are also considered.

History, Historical and Historicity in Heidegger

Directory of Open Access Journals (Sweden)

José Manuel CHILLÓN

2017-12-01

Full Text Available In order to the “Historie” is possible as “Geschichte”, that is, so that the events are more than mere collections of past vestiges, it is necessary that the historical (geschichtlich of history is understood as enshrined in the historicity, in Geschichtlichkeit. In § 6 of the Introduction to ‘Being and Time’ Heidegger understands that the historicity refers to the temporality of Dasein, to its finitude. Thiking of the historicity requires, as its main task, overcoming history as history of entities, in terms of history of forgotten being. And, of course, to think the being, the happening of being and Dasein which, as such event, is being, is occurring , it is historicizing .

Kapetanakis, S; Giovannopoulou, E; Nastoulis, E; Demetriou, T

2016-01-01

A butterfly vertebra is a rare congenital anomaly, encountered as isolated finding or as part of syndromic diseases. We report a case of a 40-year- old female presenting with low back pain and sciatica due to 'butterfly' dysplasia of the first sacral vertebra. This novel case includes posterolateral displacement of the completely separated hemivertebrae, causing left lateral recess stenosis and compression of S1 nerve root. Additionally, we conducted a short review of the literature. Few cases are reported in literature. Only one refers to a sacral vertebra. There is no previous case of a butterfly vertebra that accounts for narrowing of the lateral recess and associated radiculopathy.

Historical review of transuranic analytical methodology

International Nuclear Information System (INIS)

Wessman, R.A.; Leventhal, L.

1977-01-01

The methods used for the analysis of the transuranic elements neptunium, plutonium, americium, and curium are reviewed. Particular attention is given to those procedures suitable for low-level environmental and biological assessment. The preparation of such samples, derived from a variety of sources and incorporated in different masses and volumes of soils, water, vegetation, and biological matrices, is described. A comprehensive discussion of matrix dissolution and equilibration techniques indicates that complete dissolution employing tracer techniques is to be preferred. Leaching of large soil samples is satisfactory for worldwide fallout. Individual and sequential separation and purification procedures, including precipitation, extraction, and ion exchange methods, are described. Sample preparation techniques for radiometric assay, such as stippling, evaporation, and plating, are reviewed. For both tracer and nuclide assay, electroplating provides the thin samples suitable for alpha pulse height analysis. Past and current counting methods for the transuranic alpha, beta, and gamma emitters are reviewed

State-of-the-art of historical earthquake research in Fennoscandia and the Baltic Republics

Directory of Open Access Journals (Sweden)

V. Nikulin

2004-06-01

Full Text Available We review historical earthquake research in Northern Europe. 'Historical' is defined as being identical with seismic events occurring in the pre-instrumental and early instrumental periods between 1073 and the mid-1960s. The first seismographs in this region were installed in Uppsala, Sweden and Bergen, Norway in 1904-1905, but these mechanical pendulum instruments were broad band and amplification factors were modest at around 500. Until the 1960s few modern short period electromagnetic seismographs were deployed. Scientific earthquake studies in this region began during the first decades of the 1800s, while the systematic use of macroseismic questionnaires commenced at the end of that century. Basic research efforts have vigorously been pursued from the 1970s onwards because of the mandatory seismic risk studies for commissioning nuclear power plants in Sweden, Finland, NW Russia, Kola and installations of huge oil platforms in the North Sea. The most comprehensive earthquake database currently available for Northern Europe is the FENCAT catalogue covering about six centuries and representing the accumulation of work conducted by many scientists during the last 200 years. This catalogue is given in parametric form, while original macroseismic observations and intensity maps for the largest earthquakes can be found in various national publications, often in local languages. No database giving intensity data points exists in computerized form for the region. The FENCAT catalogue still contains some spurious events of various kinds but more serious are some recent claims that some of the presumed largest historical earthquakes have been assigned too large magnitude values, which would have implications for earthquake hazard levels implemented in national building codes. We discuss future cooperative measures such as establishing macroseismic data archives as a means for promoting further research on historical earthquakes in Northern Europe.

Using mobile phones and short message service to deliver self-management interventions for chronic conditions: a meta-review.

The worldwide burden of chronic disease is widespread and growing. This shift from acute to chronic care requires rethinking how resources are invested in managing these conditions. One response has been to create programs and interventions that have the goal of helping patients better manage their own conditions. Over time, these self-management interventions and strategies have increasingly relied on various technologies for their implementation, with the newest technology being mobile phones and short message service (SMS). The objective of this meta-review was to evaluate the current evidence on the use of mobile phones and SMS to deliver self-management interventions for chronic conditions. A meta-review was conducted of the 11 systematic reviews (SRs) that were identified and retrieved after an extensive search of electronic databases covering the years 2000-2012. Relevant information was abstracted from each systematic review and a quality assessment carried out using the AMSTAR ("A Measurement Tool to Assess Systematic Reviews") criteria. The number and types of included studies and total number of subjects varied significantly across the systematic reviews. Mobile phone text messaging was reported to significantly improve adherence to appointments and antiretroviral therapy, short-term smoking quit rates, and selected clinical and behavioral outcomes. AMSTAR scores ranged from 11 to 3, reflecting substantial variation in SR quality. Mobile phones and SMS show promise as a technology to deliver self-management interventions to improve outcomes of chronic care management. However, the quality of future studies and systematic reviews needs to be improved. There also are unresolved issues about the technology itself. © 2014 Sigma Theta Tau International.

Fox, Derek B; Roming, Peter W A

2007-05-15

We review recent observations of short-hard gamma-ray bursts and their afterglows. The launch and successful ongoing operations of the Swift satellite, along with several localizations from the High-Energy Transient Explorer mission, have provoked a revolution in short-burst studies: first, by quickly providing high-quality positions to observers; and second, via rapid and sustained observations from the Swift satellite itself. We make a complete accounting of Swift-era short-burst localizations and proposed host galaxies, and discuss the implications of these observations for the distances, energetics and environments of short bursts, and the nature of their progenitors. We then review the physical modelling of short-burst afterglows: while the simplest afterglow models are inadequate to explain the observations, there have been several notable successes. Finally, we address the case of an unusual burst that threatens to upset the simple picture in which long bursts are due to the deaths of massive stars, and short bursts to compact-object merger events.

Short-Term Memory and Aphasia: From Theory to Treatment.

Science.gov (United States)

Minkina, Irene; Rosenberg, Samantha; Kalinyak-Fliszar, Michelene; Martin, Nadine

2017-02-01

This article reviews existing research on the interactions between verbal short-term memory and language processing impairments in aphasia. Theoretical models of short-term memory are reviewed, starting with a model assuming a separation between short-term memory and language, and progressing to models that view verbal short-term memory as a cognitive requirement of language processing. The review highlights a verbal short-term memory model derived from an interactive activation model of word retrieval. This model holds that verbal short-term memory encompasses the temporary activation of linguistic knowledge (e.g., semantic, lexical, and phonological features) during language production and comprehension tasks. Empirical evidence supporting this model, which views short-term memory in the context of the processes it subserves, is outlined. Studies that use a classic measure of verbal short-term memory (i.e., number of words/digits correctly recalled in immediate serial recall) as well as those that use more intricate measures (e.g., serial position effects in immediate serial recall) are discussed. Treatment research that uses verbal short-term memory tasks in an attempt to improve language processing is then summarized, with a particular focus on word retrieval. A discussion of the limitations of current research and possible future directions concludes the review. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

Historical contributions from the Harvard system to adult spine surgery.

Schoenfeld, Andrew J

2011-10-15

Literature review. To document the historical contributions from the Harvard Medical School system to the field of adult spine surgery. Despite the fact that significant contributions to the discipline of spinal surgery have derived from the Harvard system, no prior study documents the history of the Harvard spine services in a cohesive narrative. This historical perspective reviews the history of adult spine surgery within the Harvard system and outlines the significant contributions made by orthopedic and neurosurgical practitioners to the field. Literature reviews were performed from historical works, as well as scientific publications to fashion a cohesive review covering the history of spine surgery at Harvard from the early 19th century to the present. The development of the spine surgical services at the three main Harvard hospitals, and significant spine surgical personalities within the system, are discussed, including W. Jason Mixter, MD, Joseph S. Barr Sr., MD, and Marius N. Smith-Petersen, MD. Substantial developments that have arisen from the Harvard teaching hospitals include the recognition of disc herniation as the cause of radicular symptoms in the lower extremities, the description of lumbar discectomy as a surgical treatment for radicular pain, osteotomy for the correction of spinal deformity, and the first attempt to create a systematic algorithm capable of informing treatment for cervical spine trauma. Despite humble beginnings, the surgeons and scientists at Harvard have influenced nearly every facet of spine surgery over the course of the last two centuries.

Methodological issues in systematic reviews of headache trials: adapting historical diagnostic classifications and outcome measures to present-day standards.

McCrory, Douglas C; Gray, Rebecca N; Tfelt-Hansen, Peer; Steiner, Timothy J; Taylor, Frederick R

2005-05-01

Recent efforts to make headache diagnostic classification and clinical trial methodology more consistent provide valuable advice to trialists generating new evidence on effectiveness of treatments for headache; however, interpreting older trials that do not conform to new standards remains problematic. Systematic reviewers seeking to utilize historical data can adapt currently recommended diagnostic classification and clinical trial methodological approaches to interpret all available data relative to current standards. In evaluating study populations, systematic reviewers can: (i) use available data to attempt to map study populations to diagnoses in the new International Classification of Headache Disorders; and (ii) stratify analyses based on the extent to which study populations are precisely specified. In evaluating outcome measures, systematic reviewers can: (i) summarize prevention studies using headache frequency, incorporating headache index in a stratified analysis if headache frequency is not available; (ii) summarize acute treatment studies using pain-free response as reported in directly measured headache improvement or headache severity outcomes; and (iii) avoid analysis of recurrence or relapse data not conforming to the sustained pain-free response definition.

Review of retrofit strategies decision system in historic perspective

Directory of Open Access Journals (Sweden)

M. D. Bostenaru Dan

2004-01-01

Full Text Available Urban development is a process. In structuring and developing its phases different actors are implied, who act under different, sometimes opposite, dynamic conditions and within different reference systems. This paper aims to explore the contribution of participatism to disaster mitigation, when this concerns earthquake impact on urban settlements, through the support provided to multi-criteria decision in matters of retrofit. The research broadness in field of decision making on one side and the lack of a specific model for the retrofit of existing buildings on another side led to an extensive review of the state of the art in related models to address the issue. Core idea in the selection of existing models has been the preoccupation for collaborative issues, in other words, the consideration for the different actors implied in the planning process. The historic perspective on participative planning models is made from the view of two generations of citizen implication. The first approaches focus on the participation of the building owner/inhabitant in the planning process of building construction. As current strategies building rehabilitation and selection from alternative retrofit strategies are presented. New developments include innovative models using the internet or spatial databases. The investigated participation approaches show, that participation and communication as a more comprehensive term are an old topic in the field politics-democratisation-urbanism. In all cases it can be talked of 'successful learning processes', of the improvement of the level of the professional debate. More than 30 years history of participation marked a transition in understanding the concept: from participation, based on a central decision process leading to a solution controlled and steered by the political-administrative system, to communication, characterised by simultaneous decision processes taking place outside politics and administration in co

Review of SC/RF refrigeration systems

1990-01-01

A short review is given of historical events in accelerator and cryogenic developments at both Stanford and Berkeley. Methods of refrigeration between 1.85 K and 4.5 K together with modern techniques and improvements are discussed. Where the decade of the 70's was the era of the screw compressor, the 80's can be considered that of the cold vacuum pump for superfluid cooling. Distribution methods are of major importance, and arguments can be made for bath or tube cooling, two-phase, thermo-syphon, supercritical or superfluid. System design affects reliability, safety and operating stability. Distribution costs and heat loads can be a large part of system totals. Some specific system descriptions are included. (author)

Chaudhary, Vikas; Bano, Shahina

2012-09-01

Short stature can be a sign of disease, disability, and social stigma causing psychological stress. It is important to have an early diagnosis and treatment. Short stature may result from skeletal dysplasias, endocrine disorders, may be familial, or may be the result of malnutrition and chronic illnesses. A team effort of the healthcare professionals like pediatricians, endocrinologists, radiologists, and pathologists is required to diagnose, treat and monitor various pathological conditions associated with growth abnormality. In this review, we have discussed the role of imaging in diagnosing and characterizing various pathological conditions associated with short stature.

The role of epidemiology in determining if a simple short fall can cause fatal head injury in an infant: a subject review and reflection.

Science.gov (United States)

Ehsani, Johnathon P; Ibrahim, Joseph E; Bugeja, Lyndal; Cordner, Stephen

2010-09-01

This article is a subject review summarizing and interpreting the existing knowledge on the question "Can a simple short fall cause fatal head injury in an infant?" It also reflects on the challenges of undertaking a review in the contentious area of pediatric forensic pathology. The authors identified and considered 1055 publications for inclusion. Using explicit selection criteria 27 publications were included in the subject review. The literature suggests that it is rare, but possible, for fatal head injury to occur from a simple short fall. Large population studies of childhood injuries indicate that severe head injury from a short fall is extremely rare. This is counter pointed by a single documented case report that demonstrates it can happen. The question of whether it is a credible claim in a particular case is inextricable from the circumstances of that case.To strengthen the evidence based on fatal potential of simple short falls in infants, future studies addressing this question would ideally be prospective in design and include the key elements of: (1) a large sample size, (2) clearly defined comparison groups, (3) clear and verifiable criteria for causation, (4) specified fall height, (5) specified fall type: vertical free fall or the presence of additional forces, (6) composition of contact surface, and (7) nature of contact point: concentrated to one point or onto a flat surface.We believe subject reviews for forensic pathology require a specific approach because the application of information differs between clinical and courtroom settings.

Mandibular dental arch short and long-term spontaneous dentoalveolar changes after slow or rapid maxillary expansion: a systematic review

Directory of Open Access Journals (Sweden)

Arthur César de Medeiros Alves

Full Text Available ABSTRACT Objective: The aim of this systematic review was to analyze the short and long-term spontaneous dentoalveolar changes of the mandibular dental arch after slow (SME or rapid (RME maxillary expansion in the mixed and early permanent dentitions. Methods: An electronic search was performed in the following databases: PubMed/Medline, Cochrane Library, Scopus, Embase and Web of Science. Eligibility criteria for article selection included randomized controlled trials and prospective studies written in English, with no restriction of year of publication, involving patients who underwent SME or RME during the mixed or early permanent dentitions. A double-blind search of articles was performed by two reviewers. Initially, the title and the abstract of the studies were read, and their references were also hand-searched for possible missing studies. A methodological quality scoring scale was used to analyze the selected articles. Results: The search retrieved 373 articles, but only 6 were selected for review after application of the eligibility and exclusion criteria. Non-clinically significant spontaneous dentoalveolar changes of approximately 1mm were found in the mandibular dental arch in the short and long-term, after slow or rapid maxillary expansions. Furthermore, no significant differences were found between treated and control groups. Conclusions: There is enough evidence to conclude that negligible short and long-term spontaneous dentoalveolar changes tend to occur in the mandibular dental arch after SME or RME in the mixed and early permanent dentitions. More randomized studies with appropriate control group are required to better evaluate this issue.

Investigating landslides caused by earthquakes - A historical review

Science.gov (United States)

Keefer, D.K.

2002-01-01

Post-earthquake field investigations of landslide occurrence have provided a basis for understanding, evaluating, and mapping the hazard and risk associated with earthquake-induced landslides. This paper traces the historical development of knowledge derived from these investigations. Before 1783, historical accounts of the occurrence of landslides in earthquake are typically so incomplete and vague that conclusions based on these accounts are of limited usefulness. For example, the number of landslides triggered by a given event is almost always greatly underestimated. The first formal, scientific post-earthquake investigation that included systematic documentation of the landslides was undertaken in the Calabria region of Italy after the 1783 earthquake swarm. From then until the mid-twentieth century, the best information on earthquake-induced landslides came from a succession of post-earthquake investigations largely carried out by formal commissions that undertook extensive ground-based field studies. Beginning in the mid-twentieth century, when the use of aerial photography became widespread, comprehensive inventories of landslide occurrence have been made for several earthquakes in the United States, Peru, Guatemala, Italy, El Salvador, Japan, and Taiwan. Techniques have also been developed for performing "retrospective" analyses years or decades after an earthquake that attempt to reconstruct the distribution of landslides triggered by the event. The additional use of Geographic Information System (GIS) processing and digital mapping since about 1989 has greatly facilitated the level of analysis that can applied to mapped distributions of landslides. Beginning in 1984, synthesis of worldwide and national data on earthquake-induced landslides have defined their general characteristics and relations between their occurrence and various geologic and seismic parameters. However, the number of comprehensive post-earthquake studies of landslides is still

Voi, Dante L.; Ferreira, Francisco J.O.; Stasiulevicius, Roberto; Rodrigues, Claudio; Parente, Carlos B.R.; Mazzocchi, Vera L.; Mestnik Filho, Jose; Pugliesi, Reinaldo

2011-01-01

Neutron Spectrometry and Diffraction techniques began to be studied in Brazil with the construction of the first research reactors in the years 50 and 60, and were developed with the participation of national and international scientists. In particular, we note the perseverance of the Brazilian pioneer of nuclear energy, Dr. Marcello Damy de Souza Santos, and from that time, with the involvement of some of the early pioneers, such as the physicist Roberto Stasiulevicius, who had the privilege of working in all three Brazilian nuclear research reactors. All these scientists shared half a century of acquired knowledge, helping in the training of a number of experts who are now working in national and international nuclear institutes. The present work reviews in chronological order, the testimony of the historical facts associated with the development and application of experimental techniques using neutrons as a tool for materials analysis and studies for many areas of the sciences and also with the training of personnel. IPEN, IEN and CDTN, all institutes of the CNEN-Brazil, are important in the national and international scene as a result of the research carried out there and the large number of publications produced in the field of neutron spectrometry and diffraction from experimental work carried out using the IEA (5MW), Argonauta (5kW) and more recently, the IPR (250kW) research reactors. An extensive bibliography is also presented and this can be disseminated to everyone interested. (author)

Clinical trials rarely, if ever, occur in a vacuum. Generally, large amounts of clinical data are available prior to the start of a study, particularly on the current study’s control arm. There is obvious appeal in using (i.e., ‘borrowing’) this information. With historical data providing information on the control arm, more trial resources can be devoted to the novel treatment while retaining accurate estimates of the current control arm parameters. This can result in more accurate point estimates, increased power, and reduced type I error in clinical trials, provided the historical information is sufficiently similar to the current control data. If this assumption of similarity is not satisfied, however, one can acquire increased mean square error of point estimates due to bias and either reduced power or increased type I error depending on the direction of the bias. In this manuscript, we review several methods for historical borrowing, illustrating how key parameters in each method affect borrowing behavior, and then, we compare these methods on the basis of mean square error, power and type I error. We emphasize two main themes. First, we discuss the idea of ‘dynamic’ (versus ‘static’) borrowing. Second, we emphasize the decision process involved in determining whether or not to include historical borrowing in terms of the perceived likelihood that the current control arm is sufficiently similar to the historical data. Our goal is to provide a clear review of the key issues involved in historical borrowing and provide a comparison of several methods useful for practitioners. PMID:23913901

Imaging in short stature

Directory of Open Access Journals (Sweden)

Vikas Chaudhary

2012-01-01

Full Text Available Short stature can be a sign of disease, disability, and social stigma causing psychological stress. It is important to have an early diagnosis and treatment. Short stature may result from skeletal dysplasias, endocrine disorders, may be familial, or may be the result of malnutrition and chronic illnesses. A team effort of the healthcare professionals like pediatricians, endocrinologists, radiologists, and pathologists is required to diagnose, treat and monitor various pathological conditions associated with growth abnormality. In this review, we have discussed the role of imaging in diagnosing and characterizing various pathological conditions associated with short stature.

2017-04-01

Biomaterials play a major role in interventional medicine and surgery. However, the development of biomaterials is still in its early phases in spite of the huge progress made within the last decades. On the one hand, this is because our knowledge of the molecular and cellular processes associated with biomaterials is still increasing exponentially. On the other hand, a wide variety of advanced materials with highly interesting properties is being developed currently. This review provides a short introduction into the variety of materials in use as well as their application in interventional medicine and surgery. Also the importance of biomaterials for tissue engineering in the field of regenerative medicine and the functionalisation of biomaterials, including sterilisation methods are discussed. For the future, an even broader interdisciplinary scientific collaboration is necessary in order to develop novel biomaterials and facilitate their translation into clinical practice.

2018-01-01

Full Text Available This paper examines the dynamics of Ukrainian non-financial firms' capital structure within a historical perspective. It shows that firm financing since 1990 was a derivative from economic and institutional changes, and current levels of leverage are lower than ones of foreign peers. Whereas in the short-term we can expect some market recovery, long-term dynamics relies almost exclusively on the successof institutional reforms.

Intrinsic and extrinsic carbohydrates in the vagina: A short review on vaginal glycogen.

Science.gov (United States)

Tester, Richard; Al-Ghazzewi, Farage H

2018-06-01

The reasons for (i) the presence and (ii) mechanisms of utilisation of glycogen by the lactic acid bacteria in the human vaginal tract are not well understood. It is probable that the vaginal epithelia produce both glycogen and α-amylase where the enzyme depolymerises the polysaccharide within the vagina itself. Only these depolymerised residues are then utilised for growth by the lactic acid bacteria. The lactic acid bacteria cannot metabolise the glycogen directly due to their incapacity to produce the α-amylase enzyme. These bacteria may, however, metabolise exogenous carbohydrates (such as prebiotics) selectively for growth effectively. These carbohydrate utilisation issues within the vagina are considered in this short review. Copyright © 2018 Elsevier B.V. All rights reserved.

Implementing Solar PV Projects on Historic Buildings and in Historic Districts

Energy Technology Data Exchange (ETDEWEB)

Kandt, A.; Hotchkiss, E.; Walker, A.; Buddenborg, J; Lindberg, J.

2011-09-01

Many municipalities, particularly in older communities of the United States, have a large amount of historic buildings and districts. In addition to preserving these historic assets, many municipalities have goals or legislative requirements to procure a certain amount of energy from renewable sources and to become more efficient in their energy use; often, these requirements do not exempt historic buildings. This paper details findings from a workshop held in Denver, Colorado, in June 2010 that brought together stakeholders from both the solar and historic preservation industries. Based on these findings, this paper identifies challenges and recommends solutions for developing solar photovoltaic (PV) projects on historic buildings and in historic districts in such a way as to not affect the characteristics that make a building eligible for historic status.

New Technologies and New Paradigms in Historical Research

Directory of Open Access Journals (Sweden)

Antonio Cartelli

2001-01-01

Full Text Available After a short introduction on media evolution and its implication on human history, the paper presents an account of two experiences the authors had while using new technologies in disseminating bibliographical and historical information. The first experience concerns the Web publication of a bibliography on Beneventan manuscripts and arose from the need to overcome the long de-lays in publishing printed information. The Web publication also serves as an online resource for all researchers involved in studies on the South Italian book script in the Middle Ages. The second one relates to recent studies on women copyists in the Middle Ages and uses an online database to disseminate findings on this subject. The paper then analyzes similarities and differences between the two experiences and suggests they can be seen as a source of online information for scholars. Thus, they represent a first step towards the construction of new paradigms of knowledge and research in historical studies.

FEH Local: Improving flood estimates using historical data

Directory of Open Access Journals (Sweden)

Prosdocimi Ilaria

2016-01-01

Full Text Available The traditional approach to design flood estimation (for example, to derive the 100-year flood is to apply a statistical model to time series of peak river flow measured by gauging stations. Such records are typically not very long, for example in the UK only about 10% of the stations have records that are more than 50 years in length. Along-explored way to augment the data available from a gauging station is to derive information about historical flood events and paleo-floods, which can be obtained from careful exploration of archives, old newspapers, flood marks or other signs of past flooding that are still discernible in the catchment, and the history of settlements. The inclusion of historical data in flood frequency estimation has been shown to substantially reduce the uncertainty around the estimated design events and is likely to provide insight into the rarest events which might have pre-dated the relatively short systematic records. Among other things, the FEH Local project funded by the Environment Agency aims to develop methods to easily incorporate historical information into the standard method of statistical flood frequency estimation in the UK. Different statistical estimation procedures are explored, namely maximum likelihood and partial probability weighted moments, and the strengths and weaknesses of each method are investigated. The project assesses the usefulness of historical data and aims to provide practitioners with useful guidelines to indicate in what circumstances the inclusion of historical data is likely to be beneficial in terms of reducing both the bias and the variability of the estimated flood frequency curves. The guidelines are based on the results of a large Monte Carlo simulation study, in which different estimation procedures and different data availability scenarios are studied. The study provides some indication of the situations under which different estimation procedures might give a better performance.

BOOK REVIEW: Chaos: A Very Short Introduction

Science.gov (United States)

Klages, R.

2007-07-01

This book is a new volume of a series designed to introduce the curious reader to anything from ancient Egypt and Indian philosophy to conceptual art and cosmology. Very handy in pocket size, Chaos promises an introduction to fundamental concepts of nonlinear science by using mathematics that is `no more complicated than X=2. Anyone who ever tried to give a popular science account of research knows that this is a more challenging task than writing an ordinary research article. Lenny Smith brilliantly succeeds to explain in words, in pictures and by using intuitive models the essence of mathematical dynamical systems theory and time series analysis as it applies to the modern world. In a more technical part he introduces the basic terms of nonlinear theory by means of simple mappings. He masterly embeds this analysis into the social, historical and cultural context by using numerous examples, from poems and paintings over chess and rabbits to Olbers' paradox, card games and `phynance'. Fundamental problems of the modelling of nonlinear systems like the weather, sun spots or golf balls falling through an array of nails are discussed from the point of view of mathematics, physics and statistics by touching upon philosophical issues. At variance with Laplace's demon, Smith's 21st century demon makes `real world' observations only with limited precision. This poses a severe problem to predictions derived from complex chaotic models, where small variations of initial conditions typically yield totally different outcomes. As Smith argues, this difficulty has direct implications on decision-making in everyday modern life. However, it also asks for an inherently probabilistic theory, which somewhat reminds us of what we are used to in the microworld. There is little to criticise in this nice little book except that some figures are of poor quality thus not really reflecting the beauty of fractals and other wonderful objects in this field. I feel that occasionally the book

2017-10-01

In the past century, maternal support during childbirth has been changed according to the different approaches suggested by various health care paradigms. The aim of this review was to argue the maternity supportive care paradigms of the past century and to closely analyze each paradigm. This is a historical review, in which published articles were retrieved from databases including Scopus, Science Direct, PubMed and Google Scholar. Sage Journals and Springer's publications were also searched due to the high citation rate of their articles. The keywords entered were "Labor support", "Normal delivery", "Birth attendance", "Supportive approaches", "Health care paradigms", and "Midwifery models of care". They were entered alone or in combinations using "AND". Also, Persian articles were searched in local databases including Irandoc, SID, IranMedex, and Magiran using the above-mentioned keywords in Persian. Sixty articles met inclusion criteria. The review revealed four main themes including the definitions of continuous labor support, the technocratic paradigm, the humanistic paradigm and the naturalistic paradigm as models of labor support. According to the evidence, labor support has changed from technocratic to humanistic and holistic approaches, which in turn, caused some changes in midwifery models of care used by midwives in the practice. Labor support based on the holistic approaches and the naturalistic paradigms could bring about remarkable outcomes, the most important being satisfied with the birth experience, increased mother's self-confidence, enhanced mother's ability in childbirth and better completion of the childbirth process.

Historical versus contemporary medicinal plant uses in Ghana.

Science.gov (United States)

Soelberg, J; Asase, A; Akwetey, G; Jäger, A K

2015-02-03

Three extraordinary, historical documents stemming from observations made in 1697, 1803 and 1817 quote medicinal plant uses among the Fante, Ga and Ashanti people of present-day Ghana, and can be linked to original botanical specimens in European herbaria. This provides a unique opportunity to gain insight to the historical materia medica of Ghana and compare this to contemporary medicinal plant uses. By critical literary and taxonomic review, the present study (re-)establishes the earliest known history of many important Ghanaian medicinal plants, and assesses the scale of change and loss of medicinal plant knowledge in Ghana over time. The study provides the foundation to reconstruct lost or discontinued Ghanaian plant uses in local or ethnopharmacological contexts. Historical botanical specimens were located in the herbaria of University of Copenhagen Herbarium (C) and British Museum of Natural History (BM). The classification and synonymy of the specimens were updated for the study, and the historical vernacular names and medicinal uses of the plants compared with 20th/21st century literature. The plants of the historical Ga materia medica were (re-)collected to aid in semi-structured interviews. The interviews aimed to document the contemporary uses and names of the plants among the Ga, and to determine to what extent the historical medicinal uses and names are extant. The study identified 100 species in historical medicinal use in Ghana, which could be linked to 134 unique uses and 105 vernacular names in Twi (Ashanti/Fante) and Ga. Most of the plants are common in Ghana. At least 52% of the historical vernacular names appear to still be in use today. Of the specific historical uses, 41 (31%) were traced among contemporary medicinal plant uses in Ghana and represent some of the most important Ghanaian medicinal plant species. However, 93 (69%) of the historical uses could not be traced and appears to be discontinued or forgotten. Among the Ga, two medicinal

Preprocessing Algorithm for Deciphering Historical Inscriptions Using String Metric

Lorand Lehel Toth

2016-07-01

Full Text Available The article presents the improvements in the preprocessing part of the deciphering method (shortly preprocessing algorithm for historical inscriptions of unknown origin. Glyphs used in historical inscriptions changed through time; therefore, various versions of the same script may contain different glyphs for each grapheme. The purpose of the preprocessing algorithm is reducing the running time of the deciphering process by filtering out the less probable interpretations of the examined inscription. However, the first version of the preprocessing algorithm leads incorrect outcome or no result in the output in certain cases. Therefore, its improved version was developed to find the most similar words in the dictionary by relaying the search conditions more accurately, but still computationally effectively. Moreover, a sophisticated similarity metric used to determine the possible meaning of the unknown inscription is introduced. The results of the evaluations are also detailed.

1995-01-01

We examined in this review article the behavioural and conceptual models of motor control and short-term memory which have intensively been investigated since the 1970s. First, we reviewed both the dual-storage model of short-term memory in which movement information is stored and a typical model of motor control which emphasizes the importance of efferent factors. We then examined two models of preselection effects: a cognitive model and a cognitive/ efferent model. Following this we reviewe...

Museum genomics: low-cost and high-accuracy genetic data from historical specimens.

Natural history collections are unparalleled repositories of geographical and temporal variation in faunal conditions. Molecular studies offer an opportunity to uncover much of this variation; however, genetic studies of historical museum specimens typically rely on extracting highly degraded and chemically modified DNA samples from skins, skulls or other dried samples. Despite this limitation, obtaining short fragments of DNA sequences using traditional PCR amplification of DNA has been the primary method for genetic study of historical specimens. Few laboratories have succeeded in obtaining genome-scale sequences from historical specimens and then only with considerable effort and cost. Here, we describe a low-cost approach using high-throughput next-generation sequencing to obtain reliable genome-scale sequence data from a traditionally preserved mammal skin and skull using a simple extraction protocol. We show that single-nucleotide polymorphisms (SNPs) from the genome sequences obtained independently from the skin and from the skull are highly repeatable compared to a reference genome. © 2011 Blackwell Publishing Ltd.

Using Recent BCI Literature to Deepen our Understanding of Clinical Neurofeedback: A Short Review.

Science.gov (United States)

Jeunet, Camille; Lotte, Fabien; Batail, Jean-Marie; Philip, Pierre; Micoulaud Franchi, Jean-Arthur

2018-05-15

In their recent paper, Alkoby et al. (2017) provide the readership with an extensive and very insightful review of the factors influencing NeuroFeedback (NF) performance. These factors are drawn from both the NF literature and the Brain-Computer Interface (BCI) literature. Our short review aims to complement Alkoby et al.'s review by reporting recent additions to the BCI literature. The object of this paper is to highlight this literature and discuss its potential relevance and usefulness to better understand the processes underlying NF and further improve the design of clinical trials assessing NF efficacy. Indeed, we are convinced that while NF and BCI are fundamentally different in many ways, both the BCI and NF communities could reach compelling achievements by building upon one another. By reviewing the recent BCI literature, we identified three types of factors that influence BCI performance: task-specific, cognitive/motivational and technology-acceptance-related factors. Since BCIs and NF share a common goal (i.e., learning to modulate specific neurophysiological patterns), similar cognitive and neurophysiological processes are likely to be involved during the training process. Thus, the literature on BCI training may help (1) to deepen our understanding of neurofeedback training processes and (2) to understand the variables that influence the clinical efficacy of NF. This may help to properly assess and/or control the influence of these variables during randomized controlled trials. Copyright © 2018 IBRO. Published by Elsevier Ltd. All rights reserved.

The Philippine historical earthquakecatalog: its development, current stateand future directions

Directory of Open Access Journals (Sweden)

B. C. Bautista

2004-06-01

Full Text Available This report will trace the development of the historical earthquake catalog of the Philippines, assess its present state and recommend future research directions. The current Philippine historical earthquake catalog is culled from various catalogs, both global and local, that were developed since the first Philippine catalog by Perrey was published in 1860. While early global catalogs gave simple mention of earthquakes in the Philippines, more focused earthquake catalogs about the Philippines gave more explicit descriptions of earthquake accounts and adopted descriptions by local historians. Over the years, various historians and seismologists continued to compile their catalogs whose contents depended on the author?s perspectives and purposes. These works varied from simple listings to others including detailed descriptions. It was only recently that an attempt made to parameterize the magnitudes and epicenters of Philippine historical earthquakes using magnitude-felt area relations was done. A more detailed catalog, however, is now underway that will show details of intensity distribution for each significant historical earthquake. By comparing the historical catalog with the recent catalog and assuming that the recent catalog is complete, we find that there are still a substantial amount of historical earthquakes that needs to be reviewed and located. Possible sources of new information are local libraries, museums and archives in the Philippines, Spain and other Southeast Asian countries to which the country was in contact with during historical times.

Short-term load forecasting by a neuro-fuzzy based approach

Energy Technology Data Exchange (ETDEWEB)

Ruey-Hsun Liang; Ching-Chi Cheng [National Yunlin University of Science and Technology (China). Dept. of Electrical Engineering

2002-02-01

An approach based on an artificial neural network (ANN) combined with a fuzzy system is proposed for short-term load forecasting. This approach was developed in order to reach the desired short-term load forecasting in an efficient manner. Over the past few years, ANNs have attained the ability to manage a great deal of system complexity and are now being proposed as powerful computational tools. In order to select the appropriate load as the input for the desired forecasting, the Pearson analysis method is first applied to choose two historical record load patterns that are similar to the forecasted load pattern. These two load patterns and the required weather parameters are then fuzzified and input into a neural network for training or testing the network. The back-propagation (BP) neural network is applied to determine the preliminary forecasted load. In addition, the rule base for the fuzzy inference machine contains important linguistic membership function terms with knowledge in the form of fuzzy IF-THEN rules. This produces the load correction inference from the historical information and past forecasted load errors to obtain an inferred load error. Adding the inferred load error to the preliminary forecasted load, we can obtain the finial forecasted load. The effectiveness of the proposed approach to the short-term load-forecasting problem is demonstrated using practical data from the Taiwan Power Company (TPC). (Author)

MRI assessment of bronchial compression in absent pulmonary valve syndrome and review of the syndrome

International Nuclear Information System (INIS)

Taragin, Benjamin H.; Berdon, Walter E.; Prinz, B.

2006-01-01

Absent pulmonary valve syndrome (APVS) is a rare cardiac malformation with massive pulmonary insufficiency that presents with short-term and long-term respiratory problems secondary to severe bronchial compression from enlarged central and hilar pulmonary arteries. Association with chromosome 22.Q11 deletions and DiGeorge syndrome is common. This historical review illustrates the airway disease with emphasis on assessment of the bronchial compression in patients with persistent respiratory difficulties post-valvular repair. Cases that had MRI for cardiac assessment are used to illustrate the pattern of airway disease. (orig.)

A review of short naps and sleep inertia: do naps of 30 min or less really avoid sleep inertia and slow-wave sleep?

Science.gov (United States)

Hilditch, Cassie J; Dorrian, Jillian; Banks, Siobhan

2017-04-01

Napping is a widely used countermeasure to sleepiness and impaired performance caused by sleep loss and circadian pressure. Sleep inertia, the period of grogginess and impaired performance experienced after waking, is a potential side effect of napping. Many industry publications recommend naps of 30 min or less to avoid this side effect. However, the evidence to support this advice is yet to be thoroughly reviewed. Electronic databases were searched, and defined criteria were applied to select articles for review. The review covers literature on naps of 30 min or less regarding (a) sleep inertia, (b) slow-wave sleep (SWS) and (c) the relationship between sleep inertia and SWS. The review found that although the literature on short afternoon naps is relatively comprehensive, there are very few studies on naps of 30 min or less at night. Studies have mixed results regarding the onset of SWS and the duration and severity of sleep inertia following short naps, making guidelines regarding their use unclear. The varying results are likely due to differing sleep/wake profiles before the nap of interest and the time of the day at waking. The review highlights the need to have more detailed guidelines about the implementation of short naps according to the time of the day and prior sleep/wake history. Without this context, such a recommendation is potentially misleading. Further research is required to better understand the interactions between these factors, especially at night, and to provide more specific recommendations. Copyright © 2017 Elsevier B.V.

This historical review covers the PACS development in the USA during the past 28 years from 1982 to 2010. General historical remarks of PACS and international scene in three stages from infancy, puberty to adolescence are presented. Early PACS development was mostly financed by the federal government including the National Institutes of Health (NIH) and the U.S. Army Medical Research and Materiel Command. PACS evolution went through several stages. The earliest stages included the definition of large-scale PACS, establishment of the DICOM and other standards, the development of some early key PACS related technologies, and PACS implementation strategies. The later stages were in the concept of enterprise PACS, IHE (Integrating the Healthcare Enterprise) workflow profiles, and ePR with image distribution. The current most excited accomplishment is in the development of the new field in medical imaging informatics. This review goes through these stages and events in the USA during these 28 years, whenever an event involved participants from other countries, the contributors are cited.

A 'cold-case' review of historic aboriginal and European-Australian encounters with toxic blooms of cyanobacteria.

Science.gov (United States)

Sadgrove, Nicholas John

2012-09-01

Interest in preserving the cultural knowledge of Aboriginal Australians continues to rise. Various studies have erupted which aim to redefine knowledge that was once lost or obscured in writing and hitherto ignored. Recognising and acknowledging the traditional Aboriginal knowledge of the Australian environment helps to strengthen Aboriginal identity and gives credibility to the rising paradigm of ecotechnology in historic pre-European Australia. This review aims to establish knowledge of a traditional awareness of factors leading towards eutrophication in water resource management. Journals from pioneering explorers were examined for evidence of cyanobacterial blooms and examples of Aboriginal water resource management practices that aimed at avoiding health threats from poor water quality. Some cultural practices, focused on water resource management, are discussed with brief mentioned of the Waugal. It is concluded that in some cases the incorporation of scientific laws into mythology is a form of conceptual modelling compatible with science if examined carefully.

Hujoel, Philippe; Zina, Lívia Guimarães; Cunha-Cruz, Joana

2012-01-01

Our understanding of the causes of periodontal disease have changed greatly over time. The aim of this review is to provide a critical and historical perspective, dating back over more than a century, on two competing paradigms. While we understand that this stark dichotomization may be viewed...... as extreme, and is legitimately open to challenge, it is our hope that this didactic approach will serve to stimulate debate. The distinction made focuses on whether the primary etiology involves local causes, such as dental plaque, or involves remote causes, such as nutrition, tobacco use or other systemic...... factors. We provide a brief historical overview of the local and remote cause hypotheses and discuss some key reasons why the local cause hypothesis has become dominant....

Quantitative historical change in bumblebee (Bombus spp. assemblages of red clover fields.

Directory of Open Access Journals (Sweden)

Yoko L Dupont

Full Text Available BACKGROUND: Flower visiting insects provide a vitally important pollination service for many crops and wild plants. Recent decline of pollinating insects due to anthropogenic modification of habitats and climate, in particular from 1950's onwards, is a major and widespread concern. However, few studies document the extent of declines in species diversity, and no studies have previously quantified local abundance declines. We here make a quantitative assessment of recent historical changes in bumblebee assemblages by comparing contemporary and historical survey data. METHODOLOGY/PRINCIPAL FINDINGS: We take advantage of detailed, quantitative historical survey data from the 1930's on bumblebee (Bombus spp. abundances and species composition in red clover (Trifolium pratense fields, an important floral resource and an attractant of all bumblebee species. We used the historical survey data as a pre-industrialization baseline, and repeated the same sampling protocol at nearly the same localities at present, hence setting up a historical experiment. We detected historical changes in abundances (bees/m(2 of both workers (the "pollinatory units" and queens (effective population size, in addition to species composition. In particular, long-tongued bumblebee species showed consistent and dramatic declines in species richness and abundances throughout the flowering season of red clover, while short-tongued species were largely unaffected. Of 12 Bombus species observed in the 1930's, five species were not observed at present. The latter were all long-tongued, late-emerging species. CONCLUSIONS/SIGNIFICANCE: Because bumblebees are important pollinators, historical changes in local bumblebee assemblages are expected to severely affect plant reproduction, in particular long-tubed species, which are pollinated by long-tongued bumblebees.

The purpose of this historical characterization document is to present the synthesized summaries of the historical records concerning the physical characteristics, radiological, and chemical composition of mixed wastes stored in underground double-shell tanks and the physical condition of these tanks. The double-shell tanks are located on the United States Department of Energy`s Hanford Site, approximately 25 miles northwest or Richland, Washington. The document will be used to assist in characterizing the waste in the tanks in conjunction with the current program of sampling and analyzing the tank wastes. Los Alamos National Laboratory (LANL) developed computer models that used the historical data to attempt to characterize the wastes and to generate estimates of each tank`s inventory. A historical review of the tanks may reveal anomalies or unusual contents that could be critical to characterization and post characterization activities. This document was developed by reviewing the operating plant process histories, waste transfer data, and available physical and chemical data from numerous resources. These resources were generated by numerous contractors from 1945 to the present. Waste characterization, the process of describing the character or quality of a waste, is required by Federal law (Resource Conservation and Recovery Act [RCRA]) and state law (Washington Administrative Code [WAC] 173-303, Dangerous Waste Regulations). Characterizing the waste is necessary to determine methods to safely retrieve, transport, and/or treat the wastes.

Rating of Perceived Exertion for Quantification of Training and Combat Loads During Combat Sport-Specific Activities: A Short Review.

Science.gov (United States)

Slimani, Maamer; Davis, Philip; Franchini, Emerson; Moalla, Wassim

2017-10-01

The aim of this short review was to summarize data pertaining to the rating of perceived exertion (RPE) methods (RPE value and session-RPE) during combat sport-specific activities (i.e., competition and training) based on many factors, including contest type (i.e., official vs. simulated vs. training), combat rounds, age of participants and muscle groups, and their correlation with physiological variables (i.e., blood lactate concentration [La] and heart rate [HR]). The current review shows higher RPE in a match of mixed martial arts (MMAs) than Brazilian jiu-jitsu and kickboxing matches and during the competitive period compared with the precompetitive period. This could be explained by the longer duration of bouts, the higher percentage contribution of aerobic metabolism in MMA than other combat sports and contest type differences (simulated vs. official matches). Thus, this review found significant correlations between RPE or session-RPE, [La] and HR. Particularly, there was a stronger correlation between RPE and [La] during official striking (r = 0.81) than grappling combat sports matches (r = 0.53). In addition, a variation of correlation (moderate to large) between session-RPE and HR-based methods has been reported (i.e., Edwards' training load [r ranged between 0.58 and 0.95] and Banister training impulse [r ranged between 0.52 and 0.86]). Specifically, stronger correlation was apparent in combat sport competition that required a much higher percentage contribution of aerobic metabolism (e.g., karate) and in adult athletes than anaerobic-based combat sports (e.g., taekwondo) and young athletes, respectively. Indeed, the current review highlights that the correlations between session-RPE and HR-based methods were higher during official competition than training sessions. Session-RPE was affected by participants' competitive level, the intensity of session (high vs. low), the training modalities (tactical-technical vs. technical-development vs. simulated

The mechanisms of acupuncture are poorly understood. In consequence, numerous investigators have conducted clinical trials to test the efficacy of acupuncture in various conditions. We have used PubMed database system to evaluate the number of publications in acupuncture and nuclear medicine procedures in the period from 1964 to 2007, using the keywords: 'nuclear medicine and acupuncture', 'SPECT and acupuncture, 'PET and acupuncture', 'scintigraphy and acupuncture, 'radionuclide and acupuncture', 'radiopharmaceutical and acupuncture', 'radioisotope and acupuncture' and 99m Tc and acupuncture'. Some papers published in English language were selected and a short review is presented The analysis of the number of publications shows that when a method is well accepted by the scientific community, as the methods used in nuclear medicine, the interest in the development of research increases. Moreover, important findings are presented when the nuclear medicine image is used to evaluate the effect of the acupuncture. (author)

Nuclear Activities in Argentina. A short Review. Part 2

International Nuclear Information System (INIS)

Coll, Jorge A.; Radicella, Renato

2002-01-01

The second part of this historical review covers the 'industrial' period of nuclear energy in Argentina. The National Atomic Energy Commission (CNEA), after a feasibility study carried out by argentine experts, in 1968 signed a contract to build a nuclear power plant. This PHWR plant, Atucha 1, of 310 MWe was inaugurated in 1973 and it is still operating. The same year the CNEA signed a new contract to build a CANDU type plant of 600 MWe, Embalse, that was finally inaugurated in 1983. The construction of a third plant, Atucha 2 of 745 MWe also a PHWR, was started in 1980 but was arrested in 1994, when more than 80% was completed, and it is still waiting a political decision to reach completion. Within the development of the nuclear power program, a fuel element production plant for the Argentine power reactors was built by the CNEA and a heavy water production plant of 250 tons/year was inaugurated in 1993 in the southern province of Neuquen. A pilot spent fuel reprocessing plant was designed but its construction was not completed. At the same time, a pilot gaseous diffusion plant was constructed in order to produce enriched uranium for research reactors. The activities in the field of radioisotope and radiation applications were also intensive, mainly in nuclear medicine and food preservation. A facility to fabricate sealed sources was built to process the Co 60 produced by the Embalse power plant. Argentina was active in the export of nuclear facilities: CNEA built a complete nuclear research center in Peru, and the Argentine company INVAP built research reactors in Algeria and Egypt. The same company is now building a research reactor in Australia. (author)

Analysis of bank failures during financial tumult in Africa-Zimbabwe: A historical review

Directory of Open Access Journals (Sweden)

Shewangu Dzomira

2014-09-01

Full Text Available The paper describes the analysis of the bank failures phenomenon in Africa with a deep analysis of Zimbabwe scenario. The paper is based on historical research design which used analytical and comparative research approaches to study the bank failures phenomenon. To obtain the historical evidence the researcher consulted primary sources, secondary sources and running records. It was discovered and concluded that the failing of banks was attributed to liquidity and solvency problems as a result of flawed corporate governance standards, inadequate risk management, high levels of non-performing loans and speculative activities among a confluence of factors. It was therefore recommended that enterprise-wide risk management framework should be implemented without failing and adoption of Basel II/III on banking supervision and surveillance.

Surgical treatment of pelvic organ prolapse: a historical review with emphasis on the anterior compartment.

Lensen, E J M; Withagen, M I J; Kluivers, K B; Milani, A L; Vierhout, M E

2013-10-01

The objective of this work was to collect and summarize a detailed historical review of the surgical treatment of pelvic organ prolapse (POP) in which we specifically focused on the anterior compartment. A literature search in English, Dutch, and German was carried out using the keywords pelvic organ prolapse, anterior colporrhaphy, cystocele, and interposition operations in several databases (e.g., PubMed and HathiTrust Digital Library). Other relevant journal and textbook articles were found by retrieving references cited in previous articles and textbooks. Probably the first explanation of the treatment of POP dates from 1500 B.C. The Egyptians gave a description to "falling of the womb" in the Kahun Papyrus. More than a millennium later, Euryphon, a contemporary of Hippocrates (400 B.C.) described some interesting therapeutic options, from succussion (turning a women upside down for several minutes) to irrigating the displaced uterus with wine. A wide range of techniques has been attempted to repair the prolapsing anterior vaginal wall. By 1866, Sim had already performed a series of operations very similar to a modern anterior repair. The first reviews about the abdominal approach to correcting a cystocele were in 1890. The first description of using mesh to cystoceles was the use of tantalum mesh in 1955. In 1970, the first report of collagen mesh in urogynecology was described. Nowadays, robot-assisted surgery and cell-based tissue engineering are the latest interventions. Many surgeons have tried to find the ideal surgical therapy for anterior compartment prolapse, but to date, this has not been achieved.

1976-01-01

Using historical data, a study of U.S. uranium resources was performed with emphasis on discovery and drilling rates for the time interval from 1948 until the present. The ultimate recoverable resource up to a forward cost category of $30 or less per pound is estimated to be 1,134,000 short tons--about one third the estimate offered by ERDA. A serious shortfall in uranium supply is predicted for the late 1980's if nuclear power proceeds as planned; and courses of action are recommended for uranium resource management

2015-03-01

Premature ejaculation (PE) is commonly defined as ejaculation with minimal sexual stimulation before, on or shortly after penetration and before the person wishes it. PE can be either lifelong and present since first sexual experiences (primary), or acquired (secondary), beginning later (Godpodinoff ML. Premature ejaculation: clinical subgroups and etiology. J Sex Marital Ther 1989;15:130-4). Treatments include behavioural and pharmacological interventions. To systematically review evidence for clinical effectiveness of behavioural, topical and systemic treatments for PE. The following databases were searched from inception to 6 August 2013 for published and unpublished research evidence: MEDLINE; EMBASE; Cumulative Index to Nursing and Allied Health Literature; The Cochrane Library including the Cochrane Systematic Reviews Database, Cochrane Controlled Trials Register, Database of Abstracts of Reviews of Effects and the Health Technology Assessment database; ISI Web of Science, including Science Citation Index, and the Conference Proceedings Citation Index-Science. The US Food and Drug Administration website and the European Medicines Agency (EMA) website were also searched. Randomised controlled trials (RCTs) in adult men with PE were eligible (or non-RCTs in the absence of RCTs). RCT data were extrapolated from review articles when available. The primary outcome was intravaginal ejaculatory latency time (IELT). Data were meta-analysed when possible. Other outcomes included sexual satisfaction, control over ejaculation, relationship satisfaction, self-esteem, quality of life, treatment acceptability and adverse events (AEs). A total of 103 studies (102 RCTs, 65 from reviews) were included. RCTs were available for all interventions except yoga. The following interventions demonstrated significant improvements (p < 0.05) in arithmetic mean difference in IELT compared with placebo: topical anaesthetics - eutectic mixture of local anaesthetics (EMLA(®), Astra

A short historical investigation into cross-cultural Australian ideas about the marine animal group Teredinidae, their socioecological consequences and some options

Directory of Open Access Journals (Sweden)

Mary Gardner

2013-10-01

Full Text Available How are contemporary multicultural coastal Australians, Aboriginals and settlers alike, to develop wiser ideas and practices towards marine animals as well as each other? To illustrate the importance and complexity of this question, I offer a short historical investigation of some contrasting ideas and practices held by Australian Aboriginal and settler cultures about marine animals of the group Teredinidae. I present two “screenshots”: one from the period 1798-1826 and another from 1970-2012. The first period examines a negative but influential interpretation by Thomas Malthus of a cross cultural encounter featuring Australian Aboriginal consumption of local Teredinidae known as “cobra”. While this cultural tone remains largely unchanged in the second period, the biological understanding of the marine animals has developed greatly. So has awareness of the socioecology of Teredinidae: their estuarine habitats and cultural significance. Their potential role as subjects of community based monitoring is undeveloped but could serve overlapping concerns of environmental justice as well as the restoration and “future proofing” of habitats. Such a new composite of ideas and practices will rely on better integration of biology with community based social innovations. A symbolic beginning would be a change in Australian English colloquialisms for Teredinidae, from the erroneous “shipworm” or “mangrove worm” to the more accurate “burrowing clam”.

von Bohlen, Alex; Röhrs, Stefan; Salomon, Joseph

2007-02-01

External muPIXE has been used for characterisation of small samples of varnish from historical violins, and pieces of varnished wood from historical and modern stringed instruments. To obtain spatially resolved information about the distribution of elements across the varnish layers single-spot analysis, line-scans, and area-mapping were performed. Local resolution of approximately 20 mum was obtained from the 3 MeV, 1 nA proton micro-probe. Results from simultaneous multi-element determination of Na, Mg, Al, Si, P, S, K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Br, Rb, Sr, Ag, Cd, Sn, Ba, and Pb in historical varnishes are presented. Semi-quantitative evaluation of line-scans recorded on diverse historical varnishes is reported. The applied method is discussed in detail and the results obtained are critically reviewed and compared with those in the literature.

The Energy Audit Activity Focused on the Lighting Systems in Historical Buildings

Directory of Open Access Journals (Sweden)

Giacomo Salvadori

2016-11-01

Full Text Available The energy audit for a building is a procedure designed mainly to obtain adequate knowledge of the energy consumption profile, identify, and quantify opportunities for energy savings by a cost-benefit analysis and report, clearly and comprehensively, about the obtained results. If the audit is referred to a building with a significant historical and artistic value, a compatibility evaluation of the energy saving interventions with the architectural features should also be developed. In this paper, analysing the case study of a historical building used as public offices in Pisa (Italy, the authors describe how it is possible to conduct an energy audit activity (especially dedicated to the lighting system and they show how, for this type of buildings, it is possible to obtain significant energy savings with a refurbishment of the lighting system. A total number of seven interventions on indoor and outdoor lighting sub-systems were analysed in the paper. They are characterised by absolute compatibility with the historical and artistic value of the building and they show short payback times, variable between 4 and 34 months, allowing a reduction of the electrical energy consumption for the artificial indoor and outdoor lighting variable from 1.1 MWh/year to 39.0 MWh/year. The followed methodology and the evaluation results described in the paper, although based on a case study, can be extended to numerous historical buildings used as public offices, a recurring situation in the centres of Italian historical cities.

The Historical Optimism of Boris Mironov

Directory of Open Access Journals (Sweden)

Vladimir G. Khoros

2016-10-01

Full Text Available The article attempts to assess the contribution of B.N. Mironov’s monograph “The Russian Empire: From Tradition to Modernity” to historiography. The author has reviewed other books by Mironov. While the reviewer’s assessment is positive overall, a number of points defended by the author call for a rejoinder. The reviewer agrees with the main idea of the book: there was no permanent crisis and impoverishment of the working population in the history of imperial Russia in the 18th to the beginning of 20th centuries. On the contrary, there was some progress and achievements in terms of modernization. The revolutions in the beginning of the 20th century must be explained through other reasons. Credit undoubtedly belongs to Mironov for proof of this thesis. In such an approach, the Russian past appears more complicated and realistic than in many of the preceding investigations by Russian as well as by foreign scholars. An interesting feature of Mironov’s approach is historical optimism, that is, an interpretation of Russian historical evolution as successful. However, sometimes this optimism seems excessive. Key observations are the following. First, overcoming one extreme (the permanent crisis in Russia, Mironov, to some extent, ends up at another extreme – an underestimation of those social and cultural problems in Russian society that stimulated the revolutionary climate. Second, there is an overestimation of the role of the intelligentsia as an agent of revolution, its characteristics are excessively negative, and there is an underestimation of the impulse to protest from below and the popular character of the Russian revolution of 1917. Third, despite a number of interesting ideas concerning the process of modernization in Russia, Mironov identifies this modernization with Westernization (“Europeanization”. But the author himself rightly demonstrates the difference between Russian and European civilizational values. This

Full Text Available Question: Is massage therapy effective for people with musculoskeletal disorders compared to any other treatment or no treatment? Design: Systematic review of randomised clinical trials. Participants: People with musculoskeletal disorders. Interventions: Massage therapy (manual manipulation of the soft tissues as a stand-alone intervention. Outcome: The primary outcomes were pain and function. Results: The 26 eligible randomised trials involved 2565 participants. The mean sample size was 95 participants (range 16 to 579 per study; 10 studies were considered to be at low risk of bias. Overall, low-to-moderate-level evidence indicated that massage reduces pain in the short term compared to no treatment in people with shoulder pain and osteoarthritis of the knee, but not in those with low back pain or neck pain. Furthermore, low-to-moderate-level evidence indicated that massage improves function in the short term compared to no treatment in people with low back pain, knee arthritis or shoulder pain. Low-to-very-low-level evidence from single studies indicated no clear benefits of massage over acupuncture, joint mobilisation, manipulation or relaxation therapy in people with fibromyalgia, low back pain and general musculoskeletal pain. Conclusions: Massage therapy, as a stand-alone treatment, reduces pain and improves function compared to no treatment in some musculoskeletal conditions. When massage is compared to another active treatment, no clear benefit was evident.

A systematic review of published and unpublished data on six key pathogens (Renibacterium salmoninarum, Aeromonas salmonicida, IPNV, ISAV, SAV and VHSV) found in Scottish wild and farmed fish was undertaken. Despite many reported cases in farmed fish, there was a limited number of positive samples from Scottish wild fish, however, there was evidence for interactions between wild and farmed fish. A slightly elevated IPNV prevalence was reported in wild marine fish caught close to Atlantic salmon, Salmo salar L., farms that had undergone clinical IPN. Salmonid alphavirus was isolated from wild marine fish caught near Atlantic salmon farms with a SAV infection history. Isolations of VHSV were made from cleaner wrasse (Labridae) used on Scottish Atlantic salmon farms and VHSV was detected in local wild marine fish. However, these pathogens have been detected in wild marine fish caught remotely from aquaculture sites. These data suggest that despite the large number of samples taken, there is limited evidence for clinical disease in wild fish due to these pathogens (although BKD and furunculosis historically occurred) and they are likely to have had a minimal impact on Scottish wild fish. © 2017 Crown Copyright.

Short history of PACS. Part I: USA.

Science.gov (United States)

Huang, H K

2011-05-01

This historical review covers the PACS development in the USA during the past 28 years from 1982 to 2010. General historical remarks of PACS and international scene in three stages from infancy, puberty to adolescence are presented. Early PACS development was mostly financed by the federal government including the National Institutes of Health (NIH) and the U.S. Army Medical Research and Materiel Command. PACS evolution went through several stages. The earliest stages included the definition of large-scale PACS, establishment of the DICOM and other standards, the development of some early key PACS related technologies, and PACS implementation strategies. The later stages were in the concept of enterprise PACS, IHE (Integrating the Healthcare Enterprise) workflow profiles, and ePR with image distribution. The current most excited accomplishment is in the development of the new field in medical imaging informatics. This review goes through these stages and events in the USA during these 28 years, whenever an event involved participants from other countries, the contributors are cited.

Short-term medical missions (STMMs) represent a grass-roots form of aid, transferring medical services rather than funds or equipment. The objective of this paper is to review empirical studies on social, economic and diplomatic aspects of STMMs. A systematic literature review was conducted by searching PubMed and EBSCOhost for articles published from 1947-2014 about medical missions to lower and middle income countries (LMICs). Publications focused on military, disaster and dental service trips were excluded. A data extraction process was used to identify publications relevant to our objective stated above. PubMed and EBSCOhost searches provided 4138 and 3262 articles respectively for review. Most articles that provide useful information have appeared in the current millennium and are found in focused surgical journals. Little attention is paid to aspects of volunteerism, altruism and philanthropy related to STMM activity in the literature reviewed (1 article). Evidence of professionalization remains scarce, although elements including guidelines and tactical instructions have been emerging (27 articles). Information on costs (10 articles) and commentary on the relevance of market forces (1 article) are limited. Analyses of spill-over effects, i.e., changing attitudes of physicians or their communities towards aid, and characterizations of STMMs as meaningful foreign aid or strategic diplomacy are few (4 articles). The literature on key social, economic and diplomatic aspects of STMMs and their consequences is sparse. Guidelines, tactical instructions and attempts at outcome measures are emerging that may better professionalize the otherwise unregulated activity. A broader discussion of these key aspects may lead to improved accountability and intercultural professionalism to accompany medical professionalism in STMM activity.

[The proof of paternity. An andrological-forensic challenge in historical perspective].

Science.gov (United States)

Albrecht, K; Schultheiss, D

2004-10-01

For centuries, difficulties have occurred in determining unresolved paternities. In addition to the modern standard methods, such as the examination of DNA or serological proof, expert opinion on fertility once played an important role. The andrological difference between incapability to fertilise and the inability to participate in sexual intercourse was also distinguished historically. Of special significance was the discovery of spermatozoa by the medical student Johan Ham in 1677 and their further investigation by Antoni van Leeuwenhoek.Recently, modern DNA methods have also been applied for historical investigations. Illustrious examples are the DNA analysis in the case of Kaspar Hauser of Ansbach and the dispute about Thomas Jefferson, President of the U.S., fathering a child by one of his slaves. In this discourse, a medicinal-forensic review of the development of expert opinion, illustrated with historical case studies, is given.

Annual energy review 1992

International Nuclear Information System (INIS)

1993-01-01

This eleventh edition of the Annual Energy Review (AER) presents the Energy Information Administration's historical energy statistics. For most series, statistics are given for every year from 1949 through 1992. Because coverage spans four decades, the statistics in this report are well-suited to tong-term trend analyses. The AER is comprehensive. It covers all major energy activities, including consumption, production, trade, stocks, and prices, all major energy commodities, including fossil fuels and electricity. The AER also presents statistics on some renewable energy sources. For the most part, fuel-specific data are expressed in physical units such as barrels, cubic feet, and short tons. The integrated summary data in Section 1 are expressed in Btu. The Btu values are calculated using the conversion factors in Appendix A. Statistics expressed in Btu are valuable in that they allow for comparisons among different fuels and for the calculation of in the integrated summary statistics such as US consumption of Energy. The AER emphasizes domestic energy statistics

Exploitation of Documented Historical Floods for Achieving Better Flood Defense

Full Text Available Establishing Base Flood Elevation for a stream network corresponding to a big catchment is feasible by interdisciplinary approach, involving stochastic hydrology, river hydraulics, and computer aided simulations. A numerical model calibrated by historical floods has been exploited in this study. The short presentation of the catchment of the Tisza River in this paper is followed by the overview of historical floods which hit the region in the documented period of 130 years. Several well documented historical floods provided opportunity for the calibration of the chosen numerical model. Once established, the model could be used for investigation of different extreme flood scenarios and to establish the Base Flood Elevation. The calibration has shown that the coefficient of friction in case of the Tisza River is dependent both on the actual water level and on the preceding flood events. The effect of flood plain maintenance as well as the activation of six potential detention ponds on flood mitigation has been examined. Furthermore, the expected maximum water levels have also been determined for the case if the ever observed biggest 1888 flood hit the region again. The investigated cases of flood superposition highlighted the impact of tributary Maros on flood mitigation along the Tisza River.

Dealing with Historical Discrepancies: The Recovery of National Research Experiment (NRX) Reactor Fuel Rods at Chalk River Laboratories (CRL) - 13324

International Nuclear Information System (INIS)

Vickerd, Meggan

2013-01-01

Following the 1952 National Research Experiment (NRX) Reactor accident, fuel rods which had short irradiation histories were 'temporarily' buried in wooden boxes at the 'disposal grounds' during the cleanup effort. The Nuclear Legacy Liabilities Program (NLLP), funded by Natural Resources Canada (NRCan), strategically retrieves legacy waste and restores lands affected by Atomic Energy of Canada Limited (AECL) early operations. Thus under this program the recovery of still buried NRX reactor fuel rods and their relocation to modern fuel storage was identified as a priority. A suspect inventory of NRX fuels was compiled from historical records and various research activities. Site characterization in 2005 verified the physical location of the fuel rods and determined the wooden boxes they were buried in had degraded such that the fuel rods were in direct contact with the soil. The fuel rods were recovered and transferred to a modern fuel storage facility in 2007. Recovered identification tags and measured radiation fields were used to identify the inventory of these fuels. During the retrieval activity, a discrepancy was discovered between the anticipated number of fuel rods and the number found during the retrieval. A total of 32 fuel rods and cans of cut end pieces were recovered from the specified site, which was greater than the anticipated 19 fuel rods and cans. This discovery delayed the completion of the project, increased the associated costs, and required more than anticipated storage space in the modern fuel storage facility. A number of lessons learned were identified following completion of this project, the most significant of which was the potential for discrepancies within the historical records. Historical discrepancies are more likely to be resolved by comprehensive historical record searches and site characterizations. It was also recommended that a complete review of the wastes generated, and the total affected lands as a result of this historic

Full Text Available Renal cell carcinoma is the ninth most common malignancy. The commonest histopathological type is clear cell carcinoma. The occurrence of sarcomatoid carcinoma is very rare and confers a very poor prognosis. Only 10-20% patients present with paraneoplastic syndromes. Out of the common paraneoplastic syndromes, leucocytosis is one of the least reported. Here, we present a case of sarcomatoid carcinoma of kidney who presented with low-grade fever and leucocytosis, followed by a short review of literature. This is one of the rare situations where a rare histologic variant presents with a rare finding.

Psychological Perception of Space and Time in the Historical Process

Directory of Open Access Journals (Sweden)

Konstantin V. Minyar-Beloruchev

2015-06-01

Full Text Available The paper is devoted to psychological aspects and psychological perception of spatial and temporal dimensions of the historical process. Space and time do not exist separately, they are closely interconnected: everything that happens in history has certain spatial and temporal position. From historical perspective spatial characteristics of a particular territory are twofold: territory’s psychical position remains unperturbed, while its political status and national affiliation are revised in the course of time. Territories vary in their value: the most valuable objects of physical environment such as sea-coasts, courses and estuaries of rivers, mineral deposits, industrial regions, etc. serve as objects of contention on the international arena, while areas that do not possess such characteristics can be of no interest to international actors. Historical time does not necessarily coincide with chronological time. For example, according to Eric Hobsbawm, the so-called long Nineteenth Century lasted from 1789 to 1914, while the short Twentieth Century lasted only from 1914 to 1991. Psychological time should also be taken into account – perception of relation between past, present, and future developments, as well as perception of chronological intervals within which certain historical developments take place. Time sets chronological framework for the historical process, it can be both cyclical and linear at the same time. Progress in transportation and communication leads to the situation where linear characteristics of space and time remain the same, while space compresses and time accelerates: movement of physical objects and information transfer take less and less time. Such process was ushered in during the Nineteenth Century (Transportation and Communication Revolutions and it accelerated in the Twentieth and Twenty-First Centuries. Present wars can last only months and days, not years; negotiations are conducted directly by chief

Historical freshwater fish ecology: a long-term view of distribution changes and biological invasions

Directory of Open Access Journals (Sweden)

Miguel Clavero

2015-12-01

Full Text Available Past processes and events may have an important influence on contemporaneous ecological patterns, including current human impacts on landscapes and organisms. In spite of that, most of the ecological knowledge has been built upon short-term studies, which very rarely exceed one decade. Ecology and Conservation Biology have an important lack of historical approaches, a deficiency that may become a hindrance for the management of natural systems. In this talk I will present examples of how historical information on the distribution of freshwater fish and other aquatic organisms can be used to address ecological questions. Most analyses are based on two important Spanish historical written sources: the Relaciones de Felipe II (16th century and the Madoz Dictionary (19th century. The examples considered include the European eel (Anguilla anguilla, the brown trout (Salmo trutta, the common carp (Cyprinus carpio and the white clawed crayfish (Austropotamobius italicus, among other species, as well as questions related to biological invasions, habitat loss and the impacts of global warming. The outputs of ecological research based on historical data often become useful tools for present-day biodiversity conservation planning and actions.

Historical seismicity in France. Its role in the assessment of seismic risk on French nuclear sites

International Nuclear Information System (INIS)

Levret, A.

1987-11-01

Since 1975 in order to be in conformity with the requirements of the French nuclear program, a review of historical seismicity was undertaken in France. The assessment of seismic hazard for the safety of nuclear plants is in fact based upon a seismotectonic approach which needs to take into account the seismic activity over as long a period of time as possible. The method adopted for reviewing historical earthquakes entails a systematic consultation of the original sources and a critical analysis there of in the light of the historical, geographical and political contexts of the time. The same standards apply where the acquisition of new elements of information is involved. Each item of information is assigned a degree of reliability, then compiled in a computer file, up-dated annually; this file currently contains more than 4.500 events covering a period of time of about a millenary

2005-04-01

This is an historical review and contemporary empirical evaluation of the Motivation Analysis Test (MAT), one of the first tests to take a psychometric approach to the assessment of motivation. Reviews were quite positive, but the test is now over 50 years old. Nevertheless, it employs innovations in measurement not widely used in objective measurement then or now: (1) subtests with different formats, (2) disguised items, (3) speeded administration procedures, and (4) ipsative format and scoring procedures. These issues are discussed and a contemporary sample (N = 360) obtained to evaluate the Motivation Analysis Test in light of its innovative characteristics.

Nurses' contribution to short-term humanitarian care in low- to middle-income countries: An integrative review of the literature.

To appraise the literature related to voluntary humanitarian work provided by international nurses in low- to middle-income countries. Nurses and other health professionals are engaged with both governmental and nongovernmental organisations to provide care within international humanitarian relief and development contexts. Current literature describes accounts of charitable health professional activity within short-term health-focused humanitarian trips; however, there is minimal research describing the care that nurses provide and the professional roles and tasks they fulfil whilst participating in international volunteer healthcare service. Integrative review. A search of articles published between 1995-2015 was conducted using seven bibliographic databases. Inclusion criteria incorporated nurses and allied health professionals' involvement in a volunteer short-term medical team capacity. Papers describing military and/or disaster response with a service-learning focus were excluded. Nineteen papers were selected for review, description and discussion of findings. Findings revealed limited data describing the care nurses provide and the professional roles and tasks they fulfil within the context of international humanitarian short-term medical trips. Issues raised included a description of demographic data regarding participants and sending agencies, motivation for volunteer participation, perceptions of effectiveness of particular programmes and sustainability issues related to cultural, ethical or moral obligations of foreign health professionals working in a low- to middle-income countries. Study findings highlighted that although nurses are recruited and participate in health-focused humanitarian activities in low- to middle-income countries, there is extremely limited documented research about the amount and type of care that nurses specifically provide in this context. Furthermore, when identified, it is most often hidden within studies outlining services

Short- and long-run adjustments in U.S. petroleum consumption

Huntington, Hillard G.

2010-01-01

Long-run adjustments in petroleum consumption are not only larger than short-run adjustments. They may also be motivated by entirely different price events. This analysis shows that new price peaks have both short-run and long-run consumption responses, a result that is starkly different than price changes that track previous price paths. It also establishes significant trend effects where gasoline and residual fuel oil consumption decline over time. The analysis explores these adjustments by establishing long-run cointegrating relationships for different petroleum product groupings. An important implication is that price increases above historical levels may be providing substantially greater incentives for significant long-run demand adjustments than would be the case otherwise.

Curious parallels and curious connections--phylogenetic thinking in biology and historical linguistics.

Science.gov (United States)

Atkinson, Quentin D; Gray, Russell D

2005-08-01

In The Descent of Man (1871), Darwin observed "curious parallels" between the processes of biological and linguistic evolution. These parallels mean that evolutionary biologists and historical linguists seek answers to similar questions and face similar problems. As a result, the theory and methodology of the two disciplines have evolved in remarkably similar ways. In addition to Darwin's curious parallels of process, there are a number of equally curious parallels and connections between the development of methods in biology and historical linguistics. Here we briefly review the parallels between biological and linguistic evolution and contrast the historical development of phylogenetic methods in the two disciplines. We then look at a number of recent studies that have applied phylogenetic methods to language data and outline some current problems shared by the two fields.

2007-12-01

Plant phenological observations have been found an important indicator of climate change impacts on seasonal and interannual vegetation development for the late 20th/early 21st century. Our contribution contains three parts that are essential for the understanding (part 1), the analysis (part 2) and the application (part 3) of historical phenological observations in global change research. First, we propose a definition for historical phenonolgy (Rutishauser, 2007). We shortly portray the first appearance of phenological observations in Medieval philosophical and literature sources, the usage and application of this method in the Age of Enlightenment (Carl von Linné, Charles Morren), as well as the development in the 20th century (Schnelle, Lieth) to present-day networks (COST725, USA-NPN) Second, we introduce a methodological approach to estimate 'Statistical plants' from historical phenological observations (Rutishauser et al., JGR-Biogeoscience, in press). We combine spatial averaging methods and regression transfer modeling to estimate 'statistical plant' dates from historical observations that often contain gaps, changing observers and changing locations. We apply the concept to reconstruct a statistical 'Spring plant' as the weighted mean of the flowering date of cherry and apple tree and beech budburst of Switzerland 1702- 2005. Including dating total data uncertainty we estimate 10 at interannual and 3.4 days at decadal time scales. Third, we apply two long-term phenological records to describe plant phenological response to spring temperature and reconstruct warm-season temperatures from grape harvest dates (Rutishauser et al, submitted; Meier et al, GRL, in press).

2014-01-01

Large recent fires in the western U.S. have contributed to a perception that fire exclusion has caused an unprecedented occurrence of uncharacteristically severe fires, particularly in lower elevation dry pine forests. In the absence of long-term fire severity records, it is unknown how short-term trends compare to fire severity prior to 20th century fire exclusion. This study compares historical (i.e. pre-1920) fire severity with observed modern fire severity and modeled potential fire behavior across 564,413 ha of montane forests of the Colorado Front Range. We used forest structure and tree-ring fire history to characterize fire severity at 232 sites and then modeled historical fire-severity across the entire study area using biophysical variables. Eighteen (7.8%) sites were characterized by low-severity fires and 214 (92.2%) by mixed-severity fires (i.e. including moderate- or high-severity fires). Difference in area of historical versus observed low-severity fire within nine recent (post-1999) large fire perimeters was greatest in lower montane forests. Only 16% of the study area recorded a shift from historical low severity to a higher potential for crown fire today. An historical fire regime of more frequent and low-severity fires at low elevations (historically and continue to be so today. Thinning treatments at higher elevations of the montane zone will not return the fire regime to an historic low-severity regime, and are of questionable effectiveness in preventing severe wildfires. Based on present-day fuels, predicted fire behavior under extreme fire weather continues to indicate a mixed-severity fire regime throughout most of the montane forest zone. Recent large wildfires in the Front Range are not fundamentally different from similar events that occurred historically under extreme weather conditions.

The Blind Spot. Borderline Questions of Historical Semantics between Reinhart Koselleck and Niklas Luhmann

Directory of Open Access Journals (Sweden)

Maurizio Merlo

2016-12-01

Full Text Available In the wide critical reviews that the enterprise of Begriffsgeschichte has triggered, the difficult relationship that conceptual history – in its Koselleckian declination – entertains with systemic theory has remained maybe underexposed until now. Moving from the tension between experience and historicity in Koselleck, the article reflects on the tensions that the historical-conceptual structure reveals as soon as it comes into contact with the problems of historical semantics that accompany the Luhmannian attempt of operating, in the register of second order observation, a temporal dislocation and a de-paradoxification of the paradox activated by Derrida’s différance, as constitutive of historicity. The blind spot at the bottom of Luhmannian gaze cuts out the borders of the “history” continent along the lines of the shipwreck of the classic semantics of modernity.

REMOTELY SENSED DATA FUSION IN MODERN AGE ARCHAEOLOGY AND MILITARY HISTORICAL RECONSTRUCTION

Full Text Available LiDAR technology has become one of the major remote sensing methods in the last few years. There are several areas, where the scanned 3D point clouds can be used very efficiently. In our study we review the potential applications of LiDAR data in military historical reconstruction. Obviously, the base of this kind of investigation must be the archive data, but it is an interesting challenge to integrate a cutting edge method into such tasks. The LiDAR technology can be very useful, especially in vegetation covered areas, where the conventional remote sensing technologies are mostly inefficient. We review two typical sample projects where we integrated LiDAR data in military historical GIS reconstruction. Finally, we summarize, how laser scanned data can support the different parts of reconstruction work and define the technological steps of LiDAR data processing.

2010-10-01

Chronic pancreatitis is a debilitating disease resulting in pain, intestinal malabsorption, endocrine dysfunction, and poor quality of life (QoL). Our aim was to analyze surgical outcomes for patients with chronic pancreatitis. Data for patients undergoing operations for chronic pancreatitis between 1990 and 2009 were reviewed. Demographics, operative and perioperative data, and survival were catalogued. QoL was determined (Short Form 36 and European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire + PAN-26) and compared with historical controls. The mean age was 51 +/- 2 years, 38 patients were male (53%), the most common indication was pain (71%), the etiology of pancreatitis often was alcohol, and most patients underwent a Whipple procedure (56%). Operative time was 316 +/- 17 minutes and blood loss was 363 +/- 75 mL. There were 34 complications in 30 patients (42%) and one death. QoL surveys were administered for 25 of 55 (45%) surviving patients at a mean follow-up of 72 +/- 16 months. Mean survival was 99 +/- 9 months, whereas 5- and 10-year survival were 86 and 75 per cent. QoL scores were uniformly better than historical controls. Our data demonstrate that operations for chronic pancreatitis can be performed with acceptable morbidity and mortality. Patients have excellent survival and improved QoL compared with historical controls. Surgery is an effective and durable treatment option for patients with chronic pancreatitis.

We describe a 62-year-old patient with a chronic delusional disorder who presented with severely matted hair ("plica polonica"). Until the late 19th century such dreadlocks were considered as cause, consequence and treatment of mental disease. The historical development of "plica polonica" is briefly reviewed as an example of early and once popular psychiatric disease concepts.

Anthropology and addiction: an historical review.

Science.gov (United States)

Singer, Merrill

2012-10-01

This paper reviews the world anthropology of drugs and alcohol use literature, identifying key issues addressed by anthropologists, methods and theoretical models in use, trends in focus over time and future directions. Papers and books that comprise the literature were identified through computer search using the keywords: ethnography of drug use (and variants, e.g. drug ethnography, qualitative approaches in drug research), ethnography of drinking, anthropology and drug use, and anthropology and drinking. Search engines included Google Scholar, EBSCOHost, AnthroSource and PubMed. Identified sources were read and integrated into the review. The literature search identified a rich and growing literature on the anthropology of drinking and drug use. The research and published literature on the anthropology of drug use has grown and diversified since the 1970s, found acceptance in the wider multi-disciplinary domain of alcohol and drug studies and developed beyond the socio-cultural model to include life-style, critical medical anthropology and experiential explanatory models. Anthropological research has helped to shape the field of addiction science, e.g. ethnographic studies show that the lived worlds and self-identities of drug users have cultural order and socially constructed purpose and meaning, and experiential research shows that some addictions or aspects of addictions can be affirmative, creative and sustainable, at least at the individual level. The human immunodeficiency virus/acquired immune deficiency syndrome pandemic has significantly increased anthropological research on drug-related issues world-wide. © 2012 The Author, Addiction © 2012 Society for the Study of Addiction.

During video-assisted thoracic surgery (VATS), localization is sometimes needed to detect a target lesion that is too small and/or too far from the pleura. In 1995, Kanazawa et al. developed short hookwire and suture system. Since then, this system has been placed often for selected targets before VATS in Japan. This short hookwire and suture system is a representative preoperative localization method and the placement procedure is well-established. Its placement success rates are very high (range: 97.6%-99.6%), and dislodgement of this short hookwire rarely occurs with an incidence of 0.4%-2.5%. The most common complication of short hookwire placement is pneumothorax (incidence: 32.1%-68.1%), followed by pulmonary hemorrhage (incidence: 8.9%-41.6%). Complications are frequent; however, most complications are minor and asymptomatic. Copyright © 2018 Société française de radiologie. Published by Elsevier Masson SAS. All rights reserved.

Chameleonic Theories: A Short Review

Andrea Zanzi

2015-12-01

Full Text Available In the chameleon mechanism, a field (typically scalar has a mass that depends on the matter density of the environment: the larger is the matter density, the larger is the mass of the chameleon. We briefly review some aspects of chameleonic theories. In particular, in a typical class of these theories, we discuss the lagrangian, the role of conformal transformations, the equation of motion and the thin-shell effect. We also discuss f ( R theories and chameleonic quantum gravity.

To achieve these aims, the text includes references to a review of the literature concerning comparative studies, the analysis of two fundamental moments focused on attempts to internationalize the mathematics curriculum, both of which occurred during the 20th century, and, to end, a case study emanating from an international cooperation between researchers in Brazil and Portugal.

City Walls as Historic Urban Landscape: a Case study on Participatory Education

Directory of Open Access Journals (Sweden)

Rossana Bonadei

2017-03-01

Full Text Available The concept of Historic Urban Landscape, which now guides the conservation and promotion of numerous heritage sites across the world, is based on the recognition of the complexity of the urban environment, seen as a dynamic system of cultural and natural features. This paper aims at presenting an ongoing reassessment of the meaning of a historic artefact in the city of Bergamo, Italy, which is part of a broader system of defence built by the Venetian Republic between the 15th and 17th centuries. Among the many related initiatives, one was launched by the University of Bergamo and involved nearly a hundred primary school children in a series of multidisciplinary workshops. Children worked to produce a guidebook and a short animated film aimed at reconstructing the meanings and the values embodied by the Venetian Walls, an enduring cultural icon surrounding the medieval upper town. This project is triggering both downscaling and upscaling dynamics in the regeneration process of this historic urban infrastructure. It also contributes to the creation and sharing of new meanings around this heritage, which are strongly related to its value for the citizenship as well as for the visitors.

2016-03-01

Full Text Available In this essay I show the main models used to explain the fashion system. I try to describe how these models have always show fashion as a relationship between the fashion system and the general population. To do this, firstly I make a historical tour around the most significant developments of fashion. And secondly I collect the scientific theories that have tried to explain this phenomenon. I conclude that there are three basic theories today which try to explain this relationship: the trickle-down model, the model of subcultural resistance and the virulence or contagion model. All of them are insufficient because they are not made explicit and they present serious analytical shortcomings.

Full Text Available This paper provides an analysis of the historical evolution of the European welfare state, especially after the second half of the nineteenth century. Even if one considers that social protection systems have their origins in the period of German Chancellor Otto von Bismarck, various social problems have been treated in European countries before the Bismarck’s social legislation, beginning with the sixteenth century. In this article we presented mainly (i the origins of social policy systems in Europe, as shown in the literature covered, (ii the conceptual evolution of the so-called “welfare state” and (iii the development of social security schemes based on International Labour Organization typology.

Advancing the management and control of typhoid fever: a review of the historical role of human challenge studies.

Science.gov (United States)

Waddington, Claire S; Darton, Thomas C; Woodward, William E; Angus, Brian; Levine, Myron M; Pollard, Andrew J

2014-05-01

Typhoid infection causes considerable morbidity and mortality worldwide, particularly in settings where lack of clean water and inadequate sanitation facilitate disease spread through faecal-oral transmission. Improved understanding of the pathogenesis, immune control and microbiology of Salmonella Typhi infection can help accelerate the development of improved vaccines and diagnostic tests necessary for disease control. S. Typhi is a human-restricted pathogen; therefore animal models are limited in their relevance to human infection. During the latter half of the 20th century, induced human infection ("challenge") studies with S. Typhi were used effectively to assess quantitatively the human host response to challenge and to measure directly the efficacy of typhoid vaccines in preventing clinical illness. Here, the findings of these historic challenge studies are reviewed, highlighting the pivotal role that challenge studies have had in improving our understanding of the host-pathogen interaction, and illustrating issues relevant to modern typhoid challenge model design.

2015-01-01

Full Text Available Serous papillary cystadenofibromas (SPCAFs of the fallopian tube are very rare benign tumors of the female genital tract. They are usually asymptomatic and are found incidentally. Until now, only 18 cases of this tumor have been reported in the world literature. We report a case of SPCAF of the left fallopian tube in a 30-year-old female who presented with a large abdominal mass and pain. On computed tomography, a diagnosis of ovarian neoplasm was given. However, during surgery the tumor was found to arise from the fallopian tube and was treated with tubal cystectomy with sparing of the ovary. We present this unique case on account of its rarity, unusual presentation, and huge size along with a short review of literature.

Full Text Available Since 1997, the Research Unit of Biomedical Engineering in Anesthesia and Intensive Care Medicine of Graz Medical University has been dealing with the demystification of acupuncture and examining, using non-invasive methods, how different stimulation modalities (manual needle acupuncture, laserneedle acupuncture and electro acupuncture affect peripheral and central functions. Laser is also an important instrument for acupuncture. One only needs to mention the treatment of children or of patients with needle phobia. The laserneedle acupuncture, which was examined scientifically for the first time in Graz, represents a new painless acupuncture method for which up to ten laserneedles are glued to the skin, but not stuck into it. This first part of the short review article summarizes some of the peripherally measured effects of acupuncture obtained at the Medical University of Graz within the last 10 years.

An historical framework for psychiatric nosology.

Science.gov (United States)

Kendler, K S

2009-12-01

This essay, which seeks to provide an historical framework for our efforts to develop a scientific psychiatric nosology, begins by reviewing the classificatory approaches that arose in the early history of biological taxonomy. Initial attempts at species definition used top-down approaches advocated by experts and based on a few essential features of the organism chosen a priori. This approach was subsequently rejected on both conceptual and practical grounds and replaced by bottom-up approaches making use of a much wider array of features. Multiple parallels exist between the beginnings of biological taxonomy and psychiatric nosology. Like biological taxonomy, psychiatric nosology largely began with 'expert' classifications, typically influenced by a few essential features, articulated by one or more great 19th-century diagnosticians. Like biology, psychiatry is struggling toward more soundly based bottom-up approaches using diverse illness characteristics. The underemphasized historically contingent nature of our current psychiatric classification is illustrated by recounting the history of how 'Schneiderian' symptoms of schizophrenia entered into DSM-III. Given these historical contingencies, it is vital that our psychiatric nosologic enterprise be cumulative. This can be best achieved through a process of epistemic iteration. If we can develop a stable consensus in our theoretical orientation toward psychiatric illness, we can apply this approach, which has one crucial virtue. Regardless of the starting point, if each iteration (or revision) improves the performance of the nosology, the eventual success of the nosologic process, to optimally reflect the complex reality of psychiatric illness, is assured.

To assess the short- and long-term maternal and fetal impact of metformin in pregnancy compared with insulin. We performed a comprehensive literature search of MEDLINE, EMBASE, BIOSIS, Cochrane Database of Systematic Reviews and ClinicalTrials.gov. Eligible studies were randomized control trials (RCTs) or follow-up of an RCT that: (1) compared metformin with insulin in pregnancy in women with gestational diabetes mellitus or Type 2 diabetes; and (2) reported maternal or fetal outcomes of interest. Two reviewers extracted the data, evaluated study quality and calculated pooled estimates. Sixteen studies (n = 2165 in quantitative analysis) were included. Metformin lowered the risk of neonatal hypoglycaemia [risk ratio (RR) = 0.63; 95% confidence interval (95% CI), 0.45 to 0.87], large for gestational age babies (RR = 0.80; 95% CI, 0.64 to 0.99), pregnancy-induced hypertension (RR = 0.56; 95% CI, 0.37 to 0.85) and total maternal pregnancy weight gain [mean difference (MD) -2.07; 95% CI -2.88 to -1.27]. Metformin did not increase preterm delivery (RR = 1.18; 95% CI 0.67 to 2.07), small for gestational age babies (RR = 1.20; 95% CI, 0.67 to 2.14), perinatal mortality (RR = 0.82; 95% CI, 0.17 to 3.92) or Caesarean section (RR = 0.97; 95% CI, 0.80 to 1.19). Long-term outcome information is limited. Our review found that metformin had no short-term adverse effects on pregnancy, potential benefits in the neonatal period, but limited long-term follow-up information. Prior to routine use, we recommend further follow-up studies of offspring exposed to metformin in utero. © 2016 Diabetes UK.

Solar ultraviolet irradiance variations: a review

International Nuclear Information System (INIS)

Lean, J.

1987-01-01

Despite the geophysical importance of solar ultraviolet radiation, specific aspects of its temporal variations have not yet been adequately determined experimentally, nor are the mechanisms for the variability completely understood. Satellite observations have verified the reality of solar ultraviolet irradiance variations over time scales of days and months, and model calculations have confirmed the association of these short-term variations with the evolution and rotation of regions of enhanced magnetic activity on the solar disc. However, neither rocket nor satellite measurements have yet been made with sufficient accuracy and regularity to establish unequivocally the nature of the variability over the longer time of the 11-year solar cycle. The comparative importance for the long-term variations of local regions of enhanced magnetic activity and global scale activity perturbations is still being investigated. Solar ultraviolet irradiance variations over both short and long time scales are reviewed, with emphasis on their connection to solar magnetic activity. Correlations with ground-based measures of solar variability are examined because of the importance of the ground-based observations as historical proxies of ultraviolet irradiance variations. Current problems in understanding solar ultraviolet irradiance variations are discussed, and the measurements planned for solar cycle 22, which may resolve these problems, are briefly described. copyright American Geophysical Union 1987

Reports of BRCA genetic mutations and risk of death or recurrence are inconsistent. This study aimed to compare overall and disease-free breast cancer survival rates between BRCA1/2 mutation carriers and non-carriers for short-term and long-term outcomes separately. We searched the PUBMED and EMBASE databases and retrieved 452 articles using keywords that included breast cancer, BRCA mutation, and survival. Seventeen articles were selected for systematic review and among them 11 were included in our meta-analysis. We used the random-effects model to calculate the summary hazard ratio and corresponding 95% confidence interval. BRCA1 mutation carriers had significantly lower short-term and long-term overall survival rates (OSR) relative to non-carriers (HR = 1.92 [95% CI = 1.45-2.53]; 1.33 [1.12-1.58], respectively), while both short-term and long-term OSR of BRCA2 carriers did not differ from non-carriers (HR = 1.30 [95% CI = 0.95-1.76]; 1.12 [95% CI = 0.86-1.45], respectively). For short-term progression-free survival rate (PFSR), BRCA1 mutation carriers had a significantly lower rate than non-carriers (HR = 1.54 [95% CI = 1.12-2.12]), while BRCA2 mutation carriers had a similar PFSR (HR = 1.23 [95% CI = 0.96-1.58]). For long-term PFSRs, we found no significant results. Our results suggest that BRCA1 mutation decreases short-term and long-term OSRs and short-term PFSR, however, BRCA2 mutation does not affect either short-term or long-term survival rate, which is attributed to the different carcinogenic pathways for BRCA1 and BRCA2.

Historizing epistemology in psychology.

Science.gov (United States)

Jovanović, Gordana

2010-12-01

The conflict between the psychometric methodological framework and the particularities of human experiences reported in psychotherapeutic context led Michael Schwarz to raise the question whether psychology is based on a methodological error. I take this conflict as a heuristic tool for the reconstruction of the early history of psychology, which bears witness to similar epistemological conflicts, though the dominant historiography of psychology has largely forgotten alternative conceptions and their valuable insights into complexities of psychic phenomena. In order to work against the historical amnesia in psychology I suggest to look at cultural-historical contexts which decisively shaped epistemological choices in psychology. Instead of keeping epistemology and history of psychology separate, which nurtures individualism and naturalism in psychology, I argue for historizing epistemology and for historical psychology. From such a historically reflected perspective psychology in contemporary world can be approached more critically.

STSHV a teleinformatic system for historic seismology in Venezuela

Science.gov (United States)

Choy, J. E.; Palme, C.; Altez, R.; Aranguren, R.; Guada, C.; Silva, J.

2013-05-01

From 1997 on, when the first "Jornadas Venezolanas de Sismicidad Historica" took place, a big interest awoke in Venezuela to organize the available information related to historic earthquakes. At that moment only existed one published historic earthquake catalogue, that from Centeno Grau published the first time in 1949. That catalogue had no references about the sources of information. Other catalogues existed but they were internal reports for the petroleum companies and therefore difficult to access. In 2000 Grases et al reedited the Centeno-Grau catalogue, it ended up in a new, very complete catalogue with all the sources well referenced and updated. The next step to organize historic seismicity data was, from 2004 to 2008, the creation of the STSHV (Sistema de teleinformacion de Sismologia Historica Venezolana, http://sismicidad.hacer.ula.ve ). The idea was to bring together all information about destructive historic earthquakes in Venezuela in one place in the internet so it could be accessed easily by a widespread public. There are two ways to access the system. The first one, selecting an earthquake or a list of earthquakes, and the second one, selecting an information source or a list of sources. For each earthquake there is a summary of general information and additional materials: a list with the source parameters published by different authors, a list with intensities assessed by different authors, a list of information sources, a short text summarizing the historic situation at the time of the earthquake and a list of pictures if available. There are searching facilities for the seismic events and dynamic maps can be created. The information sources are classified in: books, handwritten documents, transcription of handwritten documents, documents published in books, journals and congress memories, newspapers, seismologic catalogues and electronic sources. There are facilities to find specific documents or lists of documents with common characteristics

The Making of Compassion Stress Injury: A Review of Historical and Etiological Models toward a De-Stigmatizing Neurobehavioral Conceptualization

Directory of Open Access Journals (Sweden)

Mark Russell

2018-02-01

Full Text Available The complex interactions between empathy and vulnerability amongst those in helping professions/roles have been explored by practitioners and researchers across multiple disciplines for decades. While these explorations have spurred interest and awareness in the unique risks and protective factors of helping professions/roles, they have also resulted in myriad competing, overlapping, and/or parallel definitions, conceptualizations, terminology, and etiological attributions of adverse impacts of secondary exposure to others’ suffering. In this conceptual review, we will follow the historical origins of this phenomenon, beginning with the early 1900s with the First World War and the works of early psychiatric clinicians and moving toward recent advances in understanding etiology and conceptualization. Finally, we will provide support for the use and additional research of a proposed unifying and comprehensive conceptualization term: compassion stress injury (CSI, based on a mind-body and de-stigmatizing framework.

The original evaluation was published in 2005; this report serves as the first five-year re-evaluation. This re-evaluation includes consideration of changes within LLNL to management, to mission, and to the built environment. it also determines the status of those buildings, objects, and districts that were recommended as NRHP-eligible in the 2005 report. Buildings that were omitted from the earlier building list, those that have reached 50 years of age since the original assessment, and new buildings are also addressed in the re-evaluation.

Full Text Available Newspaper is one of the most important media as it contains the records that input the cultural data and social events, progress of national and international economical and political developments, the world’s circumstances of the time, so as transmitting information and sharing knowledge of particular regions or around the globe. However, the copyright is limited to cover the transformed entity to digital contents. In order to protect the rights of digitized-contents and restrict the scope of on-line grant of historical newspaper, it is necessary to clarify the concepts and practices. This study reveals the concepts of digital rights management via literature review that will work on both mentioned issues, so as to identify the fair use to assure the profit of digitized archive of historical newspaper.

2008-05-01

Full Text Available This book contains an empirical study of adolescents' historical perceptiveness and thus offers evidence contrary to the common stereotype that adolescents possess little, if any, consciousness of the past. A range of perception-forming models can be constructed and these can collectively be seen to represent a modern and postmodern historical consciousness. Using the methods of Grounded Theory, the author presents the reader with new perspectives on documented group interviews from the perspective of developmental/psychological hermeneutics according to WYGOTSKI and also takes into account adolescents' historical self-portraits.

Full Text Available The “unrealized architectural projects” are the building projects, carried out under the specific design task and intended to be built in a particular place (site, though, for certain reasons and circumstances, have never been constructed. However, up to the present day, the topic of the “unbuilt” has been analyzed just episodically in literature and sources. The article touches upon the historical development of unrealized architectural works, as well as their artistic value and role within various historical periods of Lithuanian architecture. One of the chapters briefly reviews the relevance and development of unrealized projects during the period since Czarist Russian occupation (1795 to the restoration of Lithuanian independence (1990. Furthermore, the deeper analysis of the Soviet period (1940–1990 “dead” architecture is presented. While exploring “the unrealized”, attention has been also paid to what was actu ally built, therefore the prevailing architectural styles, tendencies and examples of the corresponding decade (in Lithuania and worldwide have been studied.Article in Lithuanian

SWS2 visual pigment evolution as a test of historically contingent patterns of plumage color evolution in warblers.

Science.gov (United States)

Bloch, Natasha I; Morrow, James M; Chang, Belinda S W; Price, Trevor D

2015-02-01

Distantly related clades that occupy similar environments may differ due to the lasting imprint of their ancestors-historical contingency. The New World warblers (Parulidae) and Old World warblers (Phylloscopidae) are ecologically similar clades that differ strikingly in plumage coloration. We studied genetic and functional evolution of the short-wavelength-sensitive visual pigments (SWS2 and SWS1) to ask if altered color perception could contribute to the plumage color differences between clades. We show SWS2 is short-wavelength shifted in birds that occupy open environments, such as finches, compared to those in closed environments, including warblers. Phylogenetic reconstructions indicate New World warblers were derived from a finch-like form that colonized from the Old World 15-20 Ma. During this process, the SWS2 gene accumulated six substitutions in branches leading to New World warblers, inviting the hypothesis that passage through a finch-like ancestor resulted in SWS2 evolution. In fact, we show spectral tuning remained similar across warblers as well as the finch ancestor. Results reject the hypothesis of historical contingency based on opsin spectral tuning, but point to evolution of other aspects of visual pigment function. Using the approach outlined here, historical contingency becomes a generally testable theory in systems where genotype and phenotype can be connected. © 2014 The Author(s).

Health inequity, main issue of contemporary debates on public health, is based on philosophical and historical concepts that date back to the idea of justice from classic Greece. The Aristotelian approach on distributive justice and its higher form, epiekeia or equity, has been reviewed, as well as how this evolves from the Middle Ages and modernity to the heart of the debate of a variety of thinkers such as liberal Rawls and Nobel laureate Amartya Sen. On this conceptual debate lies the World Health Organization version that links equity to health determinants and intends to make it operational through the equitable provision of health services.

How to Make Historical Surveys of Nonproliferation of Nuclear Weapons

Energy Technology Data Exchange (ETDEWEB)

Jonter, Thomas [Stockholm Univ. (Sweden). Dept. of Economic History

2003-05-01

In 1998 SKI initiated a project in order to make a historical survey of the Swedish nuclear weapons research during the period 1945-2000. The survey is now fulfilled and contains of three reports. IAEA became interested in the project and accepted it in 2000 as a support program to increase transparency and to support the implementation of the Additional Protocol in Sweden. In the eyes of IAEA, the most important aim is to create knowledge and refine tools to enhance the means to strengthen the Safeguard System within the Additional Protocol. Other countries have now showed interest to follow the Swedish example and to make their own reviews of the nuclear energy and nuclear weapons research of their pasts. A co-operation between Sweden, Estonia, Finland, Lithuania and Latvia has now been initiated in order to make such historical reviews. The Swedish Nuclear Power Inspectorate is the initiator and financial supporter of the project. The cooperation project has three comprehensive goals: a. to create transparency in the nuclear energy field of the past. The intention is that the results of the conducted studies could be attached to the State Declaration according to the Additional Protocol in order to enhance transparency b. to account for the nuclear material traffic of the past and; c. to develop the competence in nuclear energy matters in general, and in particular, to extend the knowledge regarding each participating State's nuclear experience in the past. The first purpose of this paper is to describe the project and its aims. The second purpose is to present a general model of how a historical review of a State's nuclear related activities and nuclear weapons research can be designed. The model has been created in order to serve as a guide for other countries strengthening of their safeguards systems in the framework of the Additional Protocol. The third purpose is to present the pedagogy that has been used as a teaching method in order to train

Short Tools to Assess Young Children's Dietary Intake: A Systematic Review Focusing on Application to Dietary Index Research

Directory of Open Access Journals (Sweden)

Lucinda K. Bell

2013-01-01

Full Text Available Dietary indices evaluate diet quality, usually based on current dietary guidelines. Indices can therefore contribute to our understanding of early-life obesity-risk dietary behaviours. Yet indices are commonly applied to dietary data collected by onerous methods (e.g., recalls or records. Short dietary assessment instruments are an attractive alternative to collect data from which to derive an index score. A systematic review of studies published before April 2013 was conducted to identify short (≤50 items tools that measure whole-of-diet intake of young children (birth-five years and are applicable to dietary indices, in particular screening obesogenic dietary behaviours. The search identified 3686 papers of which 16, reporting on 15 tools (n=7, infants and toddlers birth-24 months; n=8, preschoolers 2–5 years, met the inclusion criteria. Most tools were food frequency questionnaires (n=14, with one innovative dietary questionnaire identified. Seven were tested for validity or reliability, and one was tested for both. Six tools (n=2, infants and toddlers; n=4, preschoolers are applicable for use with current dietary indices, five of which screen obesogenic dietary behaviours. Given the limited number of brief, valid and reliable dietary assessment tools for young children to which an index can be applied, future short tool development is warranted, particularly for screening obesogenic dietary behaviours.

Deodati, Annalisa; Cianfarani, Stefano

2011-03-11

To systematically determine the impact of growth hormone therapy on adult height of children with idiopathic short stature. Systematic review. Cochrane Central Register of Controlled Trials, Medline, and the bibliographic references from retrieved articles of randomised and non-randomised controlled trials from 1985 to April 2010. Height in adulthood (standard deviation score) and overall gain in height (SD score) from baseline measurement in childhood. Randomised and non-randomised controlled trials with height measurements for adults. Inclusion criteria were initial short stature (defined as height >2 SD score below the mean), peak growth hormone responses >10 μg/L, prepubertal stage, no previous growth hormone therapy, and no comorbid conditions that would impair growth. Adult height was considered achieved when growth rate was growth hormone treated children exceeded that of the controls by 0.65 SD score (about 4 cm). The mean height gain in treated children was 1.2 SD score compared with 0.34 SD score in untreated children. A slight difference of about 1.2 cm in adult height was observed between the two growth hormone dose regimens. In the seven non-randomised controlled trials the adult height of the growth hormone treated group exceeded that of the controls by 0.45 SD score (about 3 cm). Growth hormone therapy in children with idiopathic short stature seems to be effective in partially reducing the deficit in height as adults, although the magnitude of effectiveness is on average less than that achieved in other conditions for which growth hormone is licensed. The individual response to therapy is highly variable, and additional studies are needed to identify the responders.

The Challenge and The Prospect of Pesantren in Historical Review

Hamruni

2016-12-01

Full Text Available In historical perspective, as an Islamic educational institution, pesantren has experienced a long journey. Until the present time, there are some pesantrens that still continue the heritage of old traditions. These pesantrens are named traditional pesantren. But some others, start to open themselves and make changes in responding to the present challenges.These kinds of pesantrens are called modern pesantren. The efforts of modernization by pesantren are dilematic enough because on one side, the modernization is needed, but on the other side, it contains a very different paradigm and world’s perspective. In such situation, pesantren have to discuss those differences with the Islamic paradigm and perpective as the heritage of Islamic civilization in the enlightment era. Hopefully, pesantren is able to figure out current problems smartly with contemporary approaches.

PSYCHOLOGICAL FOUNDATIONS OF THE HISTORICAL CRITICAL PEDAGOGY AND THE FOUNDATIONS OF EDUCATIONAL OF PSYCHOLOGY HISTORICAL-CULTURAL

Directory of Open Access Journals (Sweden)

Ligia Marcia Martins

2013-12-01

Full Text Available This article presents the theoretical and methodological unity between the historical-critical pedagogy and cultural-historical psychology. It highlights, in addition to the membership of both theories to historical-dialectical materialism, the basic premises that point toward the affirmation of school education as a condition of humanization of individuals, as well as the transmission of historically systematized knowledge as one of the requirements for the achieving this purpose. In this direction, we aim to demonstrate that the historical-critical pedagogy contains, in its innerness, a solid psychological foundation, consistently built by a cultural-historical conception of man, society and educative nature that guides the relationship between them through the human vital activity, that is, through the work. It is in the core of those fundamentals that the alliance between this pedagogical theory and cultural-historical psychology is evident.

Historical research in the Hanford site waste cleanup

International Nuclear Information System (INIS)

Gerber, Michele S.

1992-01-01

This paper will acquaint the audience with role of historical research in the Hanford Site waste cleanup - the largest waste cleanup endeavor ever undertaken in human history. There were no comparable predecessors to this massive waste remediation effort, but the Hanford historical record can provide a partial road map and guide. It can be, and is, a useful tool in meeting the goal of a successful, cost-effective, safe and technologically exemplary waste cleanup. The Hanford historical record is rich and complex. Yet, it poses difficult challenges, in that no central and complete repository or data base exists, records contain obscure code words and code numbers, and the measurement systems and terminology used in the records change many times over the years. Still, these records are useful to the current waste cleanup in technical ways, and in ways that extend beyond a strictly scientific aspect. Study and presentations of Hanford Site history contribute to the huge educational and outreach tasks of helping the Site's work force deal with 'culture change' and become motivated for the cleanup work that is ahead, and of helping the public and the regulators to place the events at Hanford in the context of WWII and the Cold War. This paper traces historical waste practices and policies as they changed over the years at the Hanford Site, and acquaints the audience with the generation of the major waste streams of concern in Hanford Site cleanup today. It presents original, primary-source research into the waste history of the Hanford Site. The earliest, 1940s knowledge base, assumptions and calculations about radioactive and chemical discharges, as discussed in the memos, correspondence and reports of the original Hanford Site (then Hanford Engineer Works) builders and operators, are reviewed. The growth of knowledge, research efforts, and subsequent changes in Site waste disposal policies and practices are traced. Examples of the strengths and limitations of the

Pioneers of invasive cardiovascular medicine - Charles Theodore dotter and colleagues: Short historical review

Directory of Open Access Journals (Sweden)

Kostić Jelena

2014-01-01

Full Text Available Within modern medicine at the beginning of 21st century, we are witnessing a revolutionary development of the invasive diagnostics and therapy of cardiovascular system diseases. With the discovery of X-rays at the end of 19th century by Wilhelm Roentgen, it is appropriate to reflect on the gifted individuals whose efforts drastically altered radiology and cardiology. The early techniques used in peripheral percutaneous transluminal angioplasty form the basis for subsequent percutaneous intervention both in the peripheral and coronary arteries and are largely the contribution of Charles Dotter. The main goal of his work was the use of catheters for diagnosis and treatment in an attempt to replace the scalpel. He was 20 years ahead of his time, especially with percutaneous transluminal angioplasty. The first percutaneous transluminal angioplasty marked a new era in the treatment of peripheral atherosclerotic lesions. This practical genius dedicated his considerable energy to the belief that there is always a better way to treat disease. His personal contributions to clinical medicine, research, and teaching have saved millions of limbs and lives all over the world. European physicians, who were more open to unproven techniques, almost immediately embraced percutaneous transluminal angioplasty. Without the contribution and help of his colleagues, Forssmann, Sones and Gruntzig, all of them pioneers, nothing would be done. They were all ahead of there time and opened completely new chapter in medicine.

Full Text Available Abstract Background Treatment efficacy of physical agents in osteoarthritis of the knee (OAK pain has been largely unknown, and this systematic review was aimed at assessing their short-term efficacies for pain relief. Methods Systematic review with meta-analysis of efficacy within 1–4 weeks and at follow up at 1–12 weeks after the end of treament. Results 36 randomised placebo-controlled trials (RCTs were identified with 2434 patients where 1391 patients received active treatment. 33 trials satisfied three or more out of five methodological criteria (Jadad scale. The patient sample had a mean age of 65.1 years and mean baseline pain of 62.9 mm on a 100 mm visual analogue scale (VAS. Within 4 weeks of the commencement of treatment manual acupuncture, static magnets and ultrasound therapies did not offer statistically significant short-term pain relief over placebo. Pulsed electromagnetic fields offered a small reduction in pain of 6.9 mm [95% CI: 2.2 to 11.6] (n = 487. Transcutaneous electrical nerve stimulation (TENS, including interferential currents, electro-acupuncture (EA and low level laser therapy (LLLT offered clinically relevant pain relieving effects of 18.8 mm [95% CI: 9.6 to 28.1] (n = 414, 21.9 mm [95% CI: 17.3 to 26.5] (n = 73 and 17.7 mm [95% CI: 8.1 to 27.3] (n = 343 on VAS respectively versus placebo control. In a subgroup analysis of trials with assumed optimal doses, short-term efficacy increased to 22.2 mm [95% CI: 18.1 to 26.3] for TENS, and 24.2 mm [95% CI: 17.3 to 31.3] for LLLT on VAS. Follow-up data up to 12 weeks were sparse, but positive effects seemed to persist for at least 4 weeks after the course of LLLT, EA and TENS treatment was stopped. Conclusion TENS, EA and LLLT administered with optimal doses in an intensive 2–4 week treatment regimen, seem to offer clinically relevant short-term pain relief for OAK.

Social identities and racial integration in historically white universities: A literature review of the experiences of black students

Directory of Open Access Journals (Sweden)

Sandiso Bazana

2017-11-01

Full Text Available South African government has been promulgating pieces of legislation aimed at ensuring racial integration, especially in higher education, and indirectly enforcing acculturation in historically white universities. Studies have proven that institutional cultures in historically white universities alienate and exclude black students’ identities. These students’ sense of social identity, which includes culture, heritage, language and traditions, and consequently self-esteem and self-concept, is altered in these institutions. Research has been scant regarding the shape and form that black students’ identity assumes when they get to these spaces. Using Tajfel and Turner’s (1979 social identity theory and Berry’s (2005 theory of acculturation, this article explores the experiences of black students in negotiating their social identities in historically white universities. Evoking Steve Biko’s analysis of ‘artificial integration’ (1986, we hope to illustrate how the ‘integration’ narrative sought to discard the identity of black students and psychologically enforce a simulation of black students into white-established identities. The study has implications for policy development as we hope to sensitise theoretically the historically white universities to, apart from mere opening of spaces of learning, understand the social identity challenges of black students in these institutions.

Historical and Critical Review on Biophysical Economics

Science.gov (United States)

Adigüzel, Yekbun

2016-07-01

Biophysical economics is initiated with the long history of the relation of economics with ecological basis and biophysical perspectives of the physiocrats. It inherently has social, economic, biological, environmental, natural, physical, and scientific grounds. Biological entities in economy like the resources, consumers, populations, and parts of production systems, etc. could all be dealt by biophysical economics. Considering this wide scope, current work is a “biophysical economics at a glance” rather than a comprehensive review of the full range of topics that may just be adequately covered in a book-length work. However, the sense of its wide range of applications is aimed to be provided to the reader in this work. Here, modern approaches and biophysical growth theory are presented after the long history and an overview of the concepts in biophysical economics. Examples of the recent studies are provided at the end with discussions. This review is also related to the work by Cleveland, “Biophysical Economics: From Physiocracy to Ecological Economics and Industrial Ecology” [C. J. Cleveland, in Advances in Bioeconomics and Sustainability: Essay in Honor of Nicholas Gerogescu-Roegen, eds. J. Gowdy and K. Mayumi (Edward Elgar Publishing, Cheltenham, England, 1999), pp. 125-154.]. Relevant parts include critics and comments on the presented concepts in a parallelized fashion with the Cleveland’s work.

Historical perspective

Science.gov (United States)

Landsberg, H. E.

It was a pleasure to learn, from a recent (May 4) issue of Eos, of the formation of a permanent Committee on History of Geophysics. There is a dire need for reference material, books, and articles on geophysical history.Let me recommend to them that they take a good look at the Dictionary of the History of Science (W.F. Bynum, E.J. Browne, Roy Porter (Eds.), Princeton University Press, 494 pp., 1981). What follows is not a book review, although it may appear so. It is meant to be a challenge to place geophysics on the map in historical context. In this book, hydrology is dealt with in one sentence under the heading ‘cycle,’ geomagnetism under ‘declination and dip,’ and its history ends with Edward Sabine. Seismology appears under earthquakes. No important seismologist is mentioned. In the biographical index, Wiechert is included only for a contribution to physics. Where are Sir Harold Jeffreys, Galitzin, Gutenberg, Mohorovičić, Lehman, and many others? Meteorology ends with V. Bjerknes and Solberg; Köppen, Richardson, Rossby, and other notables [of] the last century do not seem to exist.

THE DARK FACE OF ALEXANDRE HERCULANO: HISTORICAL VIEWS OF THE EVIL IN THE CONSTRUCTION OF THE SUPERNATURAL IN “A DAMA PÉ DE CABRA”

Ana Márcia Alves Siqueira

2012-04-01

Full Text Available Genre which evokes distinct interests in the history and in the literary cri­tic, the noir literature, as it is known the supernatural stories of the XIX century, presents various branches not yet explored. In Portugal, Alexan­dre Herculano consolidates himself as the precursor of historical novels, result of the harmony between his work collecting Portuguese historical sources and his romantic esthetic project. His works, however, reveal a dark side little studied, influenced by the French noir short stories, the English horror ballad, and the German macabre narratives. This work, therefore, proposes to investigate the processes of construction of dark atmosphere in short story “A Dama Pé de Cabra” as well as to investigate how the author conciliates the compression of medieval Evil in a romantic project.

Optical coherence tomography (OCT) delivers 3-dimensional images of tissue microstructures. Although OCT imaging offers a promising high-resolution method, OCT images experience some artifacts that lead to misapprehension of tissue structures. Speckle, intensity decay, and blurring are 3 major artifacts in OCT images. Speckle is due to the low coherent light source used in the configuration of OCT. Intensity decay is a deterioration of light with respect to depth, and blurring is the consequence of deficiencies of optical components. In this short review, we summarize some of the image enhancement algorithms for OCT images which address the abovementioned artifacts. PMID:28638245

Organotins in Neuronal Damage, Brain Function, and Behavior: A Short Review

Directory of Open Access Journals (Sweden)

Igor Ferraz da Silva

2018-01-01

Full Text Available The consequences of exposure to environmental contaminants have shown significant effects on brain function and behavior in different experimental models. The endocrine-disrupting chemicals (EDC present various classes of pollutants with potential neurotoxic actions, such as organotins (OTs. OTs have received special attention due to their toxic effects on the central nervous system, leading to abnormal mammalian neuroendocrine axis function. OTs are organometallic pollutants with a tin atom bound to one or more carbon atoms. OT exposure may occur through the food chain and/or contaminated water, since they have multiple applications in industry and agriculture. In addition, OTs have been used with few legal restrictions in the last decades, despite being highly toxic. In addition to their action as EDC, OTs can also cross the blood–brain barrier and show relevant neurotoxic effects, as observed in several animal model studies specifically involving the development of neurodegenerative processes, neuroinflammation, and oxidative stress. Thus, the aim of this short review is to summarize the toxic effects of the most common OT compounds, such as trimethyltin, tributyltin, triethyltin, and triphenyltin, on the brain with a focus on neuronal damage as a result of oxidative stress and neuroinflammation. We also aim to present evidence for the disruption of behavioral functions, neurotransmitters, and neuroendocrine pathways caused by OTs.

Regulatory challenges of historic uranium mines in Canada

International Nuclear Information System (INIS)

Clement, C.H.; Stenson, R.E.

2002-01-01

The radium and uranium mining industry began in Canada in 1930 with the discovery of the Port Radium deposit in the Northwest Territories. During the 1950s more uranium mines opened across Canada. Most of these mines ceased operation by the end of the 1960s. Some were remediated by their owners, while others were abandoned. The Atomic Energy Control Board (AECB), predecessor to the Canadian Nuclear Safety Commission (CNSC), was created in 1946. However, it was not until the mid-1970s that the AECB took an active role in regulating health, safety and environmental aspects of uranium mining; so many of the older mines have never been licensed. With the coming into force of the Nuclear Safety and Control Act (NSCA) in May 2000, this situation has been reviewed. The NSCA requires a licence for the possession of nuclear substances (including uranium mine tailings), or the decommissioning of nuclear facilities (including uranium mines and mills). Furthermore, governments (federal and provincial) are also subject to the NSCA, a change from the previous legislation. The CNSC has an obligation to assess these sites, regardless of ownership, and to proceed with licensing or other appropriate regulatory action. The CNSC has reviewed the status of the twenty sites in Canada where uranium milling took place historically. Eight are already licensed. Licensing actions are being pursued at the other sites. A review of nearly 100 small uranium mining or exploration sites is also underway to determine the most appropriate regulatory approach. This paper focuses on regulatory issues surrounding the historic mining and milling sites, and the regulatory approach being taken, including licensing provincial and federal government bodies who own some of the sites, and ensuring the safe management of sites that were abandoned.

Short Review: Mitigation of Current Environmental Concerns from Methanol Synthesis

Directory of Open Access Journals (Sweden)

Andrew Young

2013-06-01

Full Text Available Methanol has become a widely used and globally distributed product. Methanol is very important due to the current depletion of fossil fuels. Industrially, methanol produced from the catalytic reaction of synthetic gas composed of hydrogen, carbon monoxide, and carbon dioxide. Methanol production has brought great attention due to carbon dioxide as the main source of greenhouse gas emissions. Combined of reducing CO2 emissions and supplying an alternative fuel source has created the idea of a carbon neutral cycle called “the methanol economy”. The best catalyst for the methanol economy would show a high CO2 conversion and high selectivity for methanol production. This paper investigates research focused on catalyst development for efficient methanol synthesis from hydrogenation of carbon dioxide through added various supports and additives such as silica, zirconium, and palladium. Catalysts that displayed the highest activity included a zirconia and silicon-titanium oxide promoted Cu/Zn/Al2O3 catalyst. Alternative method of catalyst preparation, include the oxalate-gel, solid-state reaction, co-precipitation and combustion method also investigated.  © 2013 BCREC UNDIP.

Extracting key information from historical data to quantify the transmission dynamics of smallpox

Directory of Open Access Journals (Sweden)

Brockmann Stefan O

2008-08-01

Full Text Available Abstract Background Quantification of the transmission dynamics of smallpox is crucial for optimizing intervention strategies in the event of a bioterrorist attack. This article reviews basic methods and findings in mathematical and statistical studies of smallpox which estimate key transmission parameters from historical data. Main findings First, critically important aspects in extracting key information from historical data are briefly summarized. We mention different sources of heterogeneity and potential pitfalls in utilizing historical records. Second, we discuss how smallpox spreads in the absence of interventions and how the optimal timing of quarantine and isolation measures can be determined. Case studies demonstrate the following. (1 The upper confidence limit of the 99th percentile of the incubation period is 22.2 days, suggesting that quarantine should last 23 days. (2 The highest frequency (61.8% of secondary transmissions occurs 3–5 days after onset of fever so that infected individuals should be isolated before the appearance of rash. (3 The U-shaped age-specific case fatality implies a vulnerability of infants and elderly among non-immune individuals. Estimates of the transmission potential are subsequently reviewed, followed by an assessment of vaccination effects and of the expected effectiveness of interventions. Conclusion Current debates on bio-terrorism preparedness indicate that public health decision making must account for the complex interplay and balance between vaccination strategies and other public health measures (e.g. case isolation and contact tracing taking into account the frequency of adverse events to vaccination. In this review, we summarize what has already been clarified and point out needs to analyze previous smallpox outbreaks systematically.

[Flexor tendon repair: a short story].

Science.gov (United States)

Moutet, F; Corcella, D; Forli, A; Mesquida, V

2014-12-01

This short story of flexor tendon repair aims to illustrate hesitations and wanderings of this surgery. Obviously tendon repair was very early considered, but it developed and diffused rather lately. It became a routine practice only in 20th century. This was due on the one hand, in Occident, to the Galen's dogmatic interdiction, on the other hand, to the repair difficulties of this paradoxical structure. Actually tendon is made of fibroblasts and collagen (sticky substances), and then its only goal is to move. According to this necessity, whatever the used techniques are, gliding is the final purpose. Technical evolutions are illustrated by historical contributions to flexor tendon surgery of several "giants" of hand surgery. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

Hydrodynamics experiments with soap films and soap bubbles: A short review of recent experiments

Science.gov (United States)

Kellay, H.

2017-11-01

In this short review, I focus on recent experiments that benefit from the advantages offered by the two-dimensionality of the flow in suspended thin liquid films to reconsider hydrodynamics problems which have resisted a full understanding. The first problem discussed here concerns friction drag in channel flows. The use of turbulent channel flows, using thin liquid films, allows measurements of friction drag as well as mean velocity profiles for flows with different spectral exponents. Is there a link between the spectral properties of the turbulence and the mean velocity profiles or the frictional drag? This is the first question considered. The second issue examined considers the long time dynamics of large scale vortices. These are obtained in half bubbles rendered "turbulent" through thermal convection. These vortices, which live in a quasi two-dimensional environment, have a long time dynamics where their vorticity goes through what seems to be a well-defined cycle with generic features.

High-performance liquid chromatography plays an important role in analysis of historical organic colorants. A number of papers have been published in this field over the last 30 years. Classification of the most commonly used natural dyes and an overview of high-performance liquid chromatography methods with main focus on recent works (2008 to the beginning of 2014) are provided. The review deals with an entire analytical protocol covering sample preparation, chromatographic separation, and suitable detection (UV/visible and fluorescent spectroscopy and mass spectrometric techniques). High-performance liquid chromatography has been successfully used in the complete characterization of some organic dyestuffs present in historical and art objects. The possibilities and difficulties for identification of natural sources of historical colorants are also discussed. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Historical short stories as nature of science instruction in secondary science classrooms: Science teachers' implementation and students' reactions

Science.gov (United States)

Reid-Smith, Jennifer Ann

This study explores the use of historical short stories as nature of science (NOS) instruction in thirteen secondary science classes. The stories focus on the development of science ideas and include statements and questions to draw students' and teachers' attention to key NOS ideas and misconceptions. This study used mixed methods to examine how teachers implement the stories, factors influencing teachers' implementation, the impact on students' NOS understanding, students' interest in the stories and factors correlated with their interest. Teachers' implementation decisions were influenced by their NOS understanding, curricula, time constraints, perceptions of student ability and resistance, and student goals. Teachers implementing stories at a high-level of effectiveness were more likely to make instructional decisions to mitigate constraints from the school environment and students. High-level implementers frequently referred to their learning goals for students as a rationale for implementing the stories even when facing constraints. Teachers implementing at a low-level of effectiveness were more likely to express that constraints inhibited effective implementation. Teachers at all levels of implementation expressed concern regarding the length of the stories and time required to fully implement the stories. Additionally, teachers at all levels of implementation expressed a desire for additional resources regarding effective story implementation and reading strategies. Evidence exists that the stories can be used to improve students' NOS understanding. However, under what conditions the stories are effective is still unclear. Students reported finding the stories more interesting than textbook readings and many students enjoyed learning about scientists and the development of science idea. Students' interest in the stories is correlated with their attitudes towards reading, views of effective science learning, attributions of academic success, and interest in

Integration of short bouts of physical activity into organizational routine a systematic review of the literature.

Recommended daily physical activity accumulated in short intervals (e.g., organizational routine as part of the regular "conduct of business." PubMed, MEDLINE, and Google Scholar databases were searched in August 2009 (updated search in February and July 2010) to identify relevant, peer-reviewed journal articles and abstracts on school-, worksite-, and faith-based interventions of short, structurally integrated physical activity breaks. The majority of interventions implemented daily physical activity bouts of 10-15 minutes in length. Schools were the most common settings among the 40 published articles included in this review. The rigor of the studies varied by setting, with more than 75% of worksite versus 25% of school studies utilizing RCT designs. Studies focused on a broad range of outcomes, including academic/work performance indicators, mental health outcomes, and clinical disease risk indicators, in addition to physical activity level. Physical activity was the most commonly assessed outcome in school-based studies, with more than half of studies assessing and observing improvements in physical activity outcomes following the intervention. About a quarter of worksite-based studies assessed physical activity, and the majority found a positive effect of the intervention on physical activity levels. About half of studies also observed improvements in other relevant outcomes such as academic and work performance indicators (e.g., academic achievement, cognitive performance, work productivity); psychosocial factors (e.g., stress, mood); and clinical disease risk indicators (e.g., blood pressure, BMI). The average study duration was more than 1 year, and several reported outcomes at 3-6 years. Interventions integrating physical activity into organizational routine during everyday life have demonstrated modest but consistent benefits, particularly for physical activity, and these are promising avenues of investigation. The proportionately longer-term outcomes

Complementary and alternative medicine (CAM) comprises a multitude of disciplines, for example, acupuncture, ayurvedic medicine, biofeedback, herbal medicine, and homeopathic medicine. While research on CAM interventions has increased and the CAM literature has proliferated since the mid-1990s, a number of our colleagues have expressed difficulties in deciding where to publish CAM articles. In response, we created a short guide to peer-reviewed MEDLINE-indexed journals that publish CAM articles. We examined numerous English-language sources to identify titles that met our criteria, whether specific to or overlapping CAM. A few of the resources in which we found the journal titles that we included are Alternative Medicine Foundation, American Holistic Nurses Association, CINAHL/Nursing Database, Journal Citation Reports database, MEDLINE, PubMed, and Research Council for Complementary Medicine. We organized the 69 selected titles for easy use by creating 2 user-friendly tables, one listing titles in alphabetical order and one listing them in topical categories. A few examples of the topical categories are Acupuncture, CAM (general), Chinese Medicine, Herbal/Plant/Phytotherapy, Neuroscience/Psychology, Nursing/Clinical Care. Our study is the first to list general CAM journals, specialty CAM journals, and overlapping mainstream journals that are peer reviewed, in English, and indexed in MEDLINE. Our goal was to assist both authors seeking publication and mainstream journal editors who receive an overabundance of publishable articles but must recommend that authors seek publication elsewhere due to space and priority issues. Publishing in journals indexed by and included in MEDLINE (or PubMed) ensures that citations to articles will be found easily. Copyright © 2012 Lippincott Williams & Wilkins.

Cycling with an amputation: A systematic review.

Dyer, Bryce

2016-10-01

Cycling with any form of limb amputation has progressed from an activity of leisure or rehabilitation to elite level competition as part of the Paralympic Games programme. While it is often proposed that research into sport with an amputation can be extremely limited, this study intended to identify the volume, type and historical strategy in this area. This study comprises a documented systematic literature review of cycling undertaken with any form of limb amputation. This study used four online search engines to identify relevant peer-reviewed literature. These included SPORTDiscus, CINAHL, Scopus and MEDLINE. Google Scholar was also used as a secondary source. The initial results were then subjected to a set of pre-defined inclusion criteria. The resulting publications were then analysed for content and thematic commonality. The review identified 20 articles which met pre-defined inclusion criteria. The identified peer-reviewed publications were dated from the period 2004 to 2014. Three clear themes emerged from the historical research. There was both a paucity of peer-reviewed literature with respect to cycling with an amputation and the design of adaptive or assistive technology to replace limb loss. However, publications have been rising substantially over the last 5 years. This review study established the historical strategy and content of cycling with an amputation and identified the existing research themes. This will assist in summarising the current level of knowledge and help signpost such work in the future. © The International Society for Prosthetics and Orthotics 2015.

The Mayak Production Association was the first Russian site for the production and separation of plutonium. The extensive increase in plutonium production during 1948-1955, as well as the absence of reliable waste-management technology, resulted in significant releases of liquid radioactive effluent into the rather small Techa River. This resulted in chronic external and internal exposure of about 30,000 residents of riverside communities; these residents form the cohort of an epidemiologic investigation. Analysis of the available historical monitoring data indicates that the following reliable data sets can be used for reconstruction of doses received during the early periods of operation of the Mayak Production Association: Temporal pattern of specific beta activity of river water for several sites in the upper Techa region since July 1951; average annual values of specific beta activity of river water and bottom sediments as a function of downstream distance for the whole river since 1951; external gamma-exposure rates near the shoreline as a function of downstream distance for the whole Techa River since 1952; and external gamma-exposure rate as a function of distance from the shoreline for several sites in the upper and middle Techa since 1951.

Numerical risk estimates are, today, based on large epidemiological studies, and the observations on the A-bomb survivors are outlined as the primary source of information. Since the epidemiological findings are obtained from relatively high radiation exposures, extrapolations are required to the much lower doses that are relevant to radiation protection. The evolution of extrapolation procedures up to current attempts at mechanistic modelling is outlined, and some of the open issues are reviewed. (author)

Control rod designs and materials have evolved in response to performance problems in both PWRs and BWRs. Irradiation-assisted stress corrosion cracking (IASCC) due to absorber swelling has primarily affected BWR control rods with B 4 C absorbers, but has also occurred in PWRs with Ag-In-Cd absorbers. The primary problems for some designs of PWR control rods have been wear of the rodlets against upper internal components and swelling with tip wear and cracking. Competition amongst vendors for supplying control rod reloads has also resulted in design improvements. This paper provides an historical review of PWR and BWR control rod designs, their problems and remedies. (author)

Cianci, Paul; Slade, John B

2006-10-01

Most cases of decompression sickness (DCS) in the U.S. are treated with hyperbaric oxygen using U.S. Navy Treatment Tables 5 and 6, although detailed analysis shows that those tables were based on limited data. We reviewed the development of these protocols and offer an alternative treatment table more suitable for monoplace chambers that has proven effective in the treatment of DCS in patients presenting to our facility. We reviewed the outcomes for 140 cases of DCS in civilian divers treated with the shorter tables at our facility from January 1983 through December 2002. Onset of symptoms averaged 9.3 h after surfacing. At presentation, 44% of the patients demonstrated mental aberration. The average delay from onset of symptoms to treatment was 93.5 h; median delay was 48 h. Complete recovery in the total group of 140 patients was 87%. When 30 patients with low probability of DCS were excluded, the recovery rate was 98%. All patients with cerebral symptoms recovered. Patients with the highest severity scores showed a high rate of complete recovery (97.5%). Short oxygen treatment tables as originally described by Hart are effective in the treatment of DCS, even with long delays to definitive recompression that often occur among civilian divers presenting to a major Divers Alert Network referral center.

Hydrogeochemical Investigations of Historic Mining Districts, Central Western Slope of Colorado, Including Influence on Surface-Water Quality

Science.gov (United States)

Nash, J. Thomas

2002-01-01

This report describes reconnaissance hydrogeochemical investigations of 22 mining districts on the Western Slope of Colorado in the Gunnison and Uncompahgre National Forests and adjacent public lands administered by the Bureau of Land Management. Sources and fates of contaminants from historic mines, mine waste, and mill tailings are interpreted from chemical analyses for 190 samples of surface waters; 185 samples of mined rocks, mill tailings, and altered rocks; and passive leach analyses of 116 samples of those mineralized materials. Short reaches of several headwater streams show relatively low level effects of historic mining; the headwaters of the Uncompahgre River are highly contaminated by mines and unmined altered rocks in the Red Mountain district. There is encouraging evidence that natural processes attenuate mine-related contamination in most districts.

Giampouris, Dimitris

2017-01-01

Cryptographic protocols and mechanisms are widely investigated under the notion of quantum computing. Quantum cryptography offers particular advantages over classical ones, whereas in some cases established protocols have to be revisited in order to maintain their functionality. The purpose of this paper is to provide the basic definitions and review the most important theoretical advancements concerning the BB84 and E91 protocols. It also aims to offer a summary on some key developments on the field of quantum key distribution, closely related with the two aforementioned protocols. The main goal of this study is to provide the necessary background information along with a thorough review on the theoretical aspects of QKD, concentrating on specific protocols. The BB84 and E91 protocols have been chosen because most other protocols are similar to these, a fact that makes them important for the general understanding of how the QKD mechanism functions.

Role of tear location on outcomes of open primary repair of the anterior cruciate ligament: A systematic review of historical studies.

van der List, Jelle P; DiFelice, Gregory S

2017-10-01

The general opinion is that outcomes of open primary repair of the anterior cruciate ligament (ACL) in the historical literature were disappointing. Since good outcomes of primary repair of proximal tears have recently been reported, we aimed to assess the role of tear location on open primary repair outcomes in the historical literature. All studies reporting outcomes of open primary ACL repair published between the inception of PubMed, Embase and Cochrane and 2000 were identified. Studies were included if tear location was reported. Outcome scores, return to sports, stability examinations, failures and patient satisfaction were collected and reviewed in the total study cohort and in a subgroup of studies treating only proximal tears. Spearman correlation analysis was performed between the percentage of proximal tears in the studies and all outcomes. Twenty-nine studies were included reporting outcomes of open primary in 1457 patients of which 72% had proximal and 23% midsubstance tears. Mean age was 30years, 65% were males, and mean follow-up was 3.6years. Good outcomes were noted in the total cohort, and excellent outcomes were noted following repair of proximal tears. Positive correlation was found between the percentage proximal tears in the studies and percentage satisfied patients (p=0.010). Tear location seems to have played a role on the outcomes of open primary ACL repair. Outcomes of open primary repair in patients with proximal tears were excellent, which confirms there may be a potential role for primary repair as treatment for proximal ACL tears.

Szabó, Péter

2014-01-01

The term ‘historical ecology’ has been used with various meanings since the first half of the 20th century. Studies labelled as historical ecology have been produced in at least four academic disciplines: history, ecology, geography and anthropology. Although all those involved seem to agree that historical ecology concerns the historical interconnectedness of nature and human culture, this field of study has no unified methodology, specialized institutional background and c...

[Historical causality and relative contemporaneity Einsteinian relativity in the historical sciences].

Bontems, Vincent

2014-01-01

The construction of historical frame of reference based on the distinction between and articulation of phenomenological and chronological times. As it relativises the notion of simultaneity and inverts its relation to causality, the special theory of relativity can induce analogous modes of reflection on the themes of "contemporaneity" in the history of art (Panofsky) and in epistemology (Bachelard). This "relativist" method, often misunderstood, sheds light on both historical and presentist methods.

Quantum Mechanics (QM) is one of the pillars of modern physics: an impressive amount of experiments have confirmed this theory and many technological applications are based on it. Nevertheless, at one century since its development, various aspects concerning its very foundations still remain to be clarified. Among them, the transition from a microscopic probabilistic world into a macroscopic deterministic one and quantum non-locality. A possible way out from these problems would be if QM represents a statistical approximation of an unknown deterministic theory. This review is addressed to present the most recent progresses on the studies related to hidden variable theories (HVT), both from an experimental and a theoretical point of view, giving a larger emphasis to results with a direct experimental application. More in details, the first part of the review is a historical introduction to this problem. The Einstein-Podolsky-Rosen argument and the first discussions about HVT are introduced, describing the fundamental Bell's proposal for a general experimental test of every local HVT and the first attempts to realise it. The second part of the review is devoted to elucidate the recent progresses toward a conclusive Bell inequalities experiment obtained with entangled photons and other physical systems. Finally, the last sections are targeted to shortly discuss non-local HVT.

Leahy, Laura G

2017-09-01

As a new school year approaches, nurses will find themselves faced with students with symptoms of attention-deficit/hyperactivity disorder (ADHD). Navigating the diagnostic label changes and numerous psychopharmacological treatment options can prove time-consuming and confusing. The current article explores the early years of symptom identification, various diagnostic labels, and subsequent psychopharmacological treatments from psychostimulants to non-stimulant alternatives (including a prescription medical food). The current article also serves as a discussion guide for nurses and clinicians when providing education to patients and their loved ones, teachers, coaches, and others who may question the diagnosis and treatment of ADHD. This disorder can have a significant impact on one's ability to function within family, school, work, and social settings. A historical context is provided for the evolution of today's diagnostic criteria and the pharmacotherapy used in the treatment of ADHD.

The use of standardised short-term and working memory tests in aphasia research: a systematic review.

Science.gov (United States)

Murray, Laura; Salis, Christos; Martin, Nadine; Dralle, Jenny

2018-04-01

Impairments of short-term and working memory (STM, WM), both verbal and non-verbal, are ubiquitous in aphasia. Increasing interest in assessing STM and WM in aphasia research and clinical practice as well as a growing evidence base of STM/WM treatments for aphasia warrant an understanding of the range of standardised STM/WM measures that have been utilised in aphasia. To date, however, no previous systematic review has focused on aphasia. Accordingly, the goals of this systematic review were: (1) to identify standardised tests of STM and WM utilised in the aphasia literature, (2) to evaluate critically the psychometric strength of these tests, and (3) to appraise critically the quality of the investigations utilising these tests. Results revealed that a very limited number of standardised tests, in the verbal and non-verbal domains, had robust psychometric properties. Standardisation samples to elicit normative data were often small, and most measures exhibited poor validity and reliability properties. Studies using these tests inconsistently documented demographic and aphasia variables essential to interpreting STM/WM test outcomes. In light of these findings, recommendations are provided to foster, in the future, consistency across aphasia studies and confidence in STM/WM tests as assessment and treatment outcome measures.

Historical hydronuclear testing: Characterization and remediation technologies

Energy Technology Data Exchange (ETDEWEB)

Shaulis, L.; Wilson, G.; Jacobson, R.

1997-09-01

This report examines the most current literature and information available on characterization and remediation technologies that could be used on the Nevada Test Site (NTS) historical hydronuclear test areas. Historical hydronuclear tests use high explosives and a small amount of plutonium. The explosion scatters plutonium within a contained subsurface environment. There is currently a need to characterize these test areas to determine the spatial extent of plutonium in the subsurface and whether geohydrologic processes are transporting the plutonium away from the event site. Three technologies were identified to assist in the characterization of the sites. These technologies are the Pipe Explorer{trademark}, cone penetrometer, and drilling. If the characterization results indicate that remediation is needed, three remediation technologies were identified that should be appropriate, namely: capping or sealing the surface, in situ grouting, and in situ vitrification. Capping the surface would prevent vertical infiltration of water into the soil column, but would not restrict lateral movement of vadose zone water. Both the in situ grouting and vitrification techniques would attempt to immobilize the radioactive contaminants to restrict or prevent leaching of the radioactive contaminants into the groundwater. In situ grouting uses penetrometers or boreholes to inject the soil below the contaminant zone with low permeability grout. In situ vitrification melts the soil containing contaminants into a solid block. This technique would provide a significantly longer contaminant immobilization, but some research and development would be required to re-engineer existing systems for use at deep soil depths. Currently, equipment can only handle shallow depth vitrification. After existing documentation on the historical hydronuclear tests have been reviewed and the sites have been visited, more specific recommendations will be made.

Vanengelsdorp, Dennis; Meixner, Marina Doris

2010-01-01

Honey bees are a highly valued resource around the world. They are prized for their honey and wax production and depended upon for pollination of many important crops. While globally honey bee populations have been increasing, the rate of increase is not keeping pace with demand. Further, honey bee populations have not been increasing in all parts of the world, and have declined in many nations in Europe and in North America. Managed honey bee populations are influenced by many factors including diseases, parasites, pesticides, the environment, and socio-economic factors. These factors can act alone or in combination with each other. This review highlights the present day value of honey bees, followed by a detailed description of some of the historical and present day factors that influence honey bee populations, with particular emphasis on colony populations in Europe and the United States.

Climate, environment and society in southern Italy during the last 2000 years. A review of the environmental, historical and archaeological evidence

2016-03-01

This paper examines the interrelationship between the natural and human history of Sicily over the last 2000 years. It presents a close comparison of the data from the key multi-proxy site of Lago di Pergusa - located inland in the eastern part of Sicily - with the existing archaeological and textual evidence on the socio-economic processes. The article also includes a review of the available natural proxy archives from the Central Mediterranean. On the basis of the isotope and pollen data from the Lago di Pergusa core PRG2, we identified two humid periods (ca. 450-750 AD and ca. 1400-1800 AD) as well as a dry one (ca. 1100-1350 AD); our evidence corresponds closely with other environmental palaeoclimate proxies from the Mediterranean region. In our synthesis of the environmental, historical and archaeological evidence from southern Italy, we argue that during both periods of increased humidity - that is during the late antique-Byzantine times and during the late medieval and early modern periods - intense agricultural use of the Sicilian landscape developed on an unprecedented scale. This in turn contributed to the impressive demographic and economic expansion visible during these periods. A sudden period of aridity followed the first of these eras of humidity-related agricultural growth. This climatic shift, dated to around 750 AD, corresponds to a decrease in synanthropic taxa and a recovery of arboreal vegetation. We argue that in this case a climatic change contributed to socio-economic decline. Moreover, as this change occurred prior to the Arab invasion of Sicily in AD 827, the environmental processes may help to explain the collapse of Byzantine society on Sicily which, in turn made the Muslim conquest possible. After this event, there occurred a longer period of agricultural decline, lasting until around 1000 AD, after which we see the first signs of a slow recovery. Ongoing research in nearby archaeological sites will help defining if it was a local

It’s About Valence: Historical Continuity or Historical Discontinuity as a Threat to Social Identity

Directory of Open Access Journals (Sweden)

Jenny Roth

2017-08-01

Full Text Available National identity is underpinned by historical representations. Recent research shows that narratives presenting an in-group’s history as discontinuous rather than continuous raise collective angst, suggesting that historical discontinuity threatens social identity. This previous research has focused on positive aspects of an in-group’s past. The present research aims to extend the findings to go beyond positive histories. We suggest that when the in-group’s actions in the past are presented as negative, historical continuity instead of discontinuity will increase perceived identity threat because a negative, continuous history threatens group members’ need for a positive social identity in the present. In an experiment with a sample size of N = 316, we manipulated the narrated valence of in-group actions during the historical event of the approval of the German constitutional law by framing the group’s actions in either positive or negative terms. In addition, we presented the in-group’s history as connected or disconnected to the in-group’s present. Results demonstrate that historical continuity only decreased identity threat compared to historical discontinuity when the in-group’s past behavior was presented as positive. When the in-group’s past was presented as negative, continuity even increased identity threat compared to historical discontinuity. These results were particularly pronounced for people who strongly identified with their national in-group. We discuss implications of the findings for political communication and managing a nation’s perception of social identity threat.

Full Text Available Language can change and develop by itself slowly. Language can change and development because of adaptation of development and pattern change and system of society life, such as level of education, social, culture and technology mastery. Language change and development can occur internally and externally. In this article the changes internally and language development will be reviewed by looking through the study of historical change and development language based on the history of its development. While changes in external and development will be explored through the study of Sociolinguistics by examining and looking at changes and developments that language is influenced by socio-cultural factors that occur in society. Changes internally initially occurred in the behavior of speakers in their everyday lives to adjust to each other, and followed by a tendency to innovate in groups of people who are already familiar, then followed by other changes in sequence, which ultimately makes a language different each other, although originally derived from a single language family. Changes in the external language change and language development is caused by the contact of a language with other languages, where humans as social beings who have been cultured either interconnected or inter-ethnic nations in the world in a country.

Short-term plasticity as a neural mechanism supporting memory and attentional functions.

Science.gov (United States)

Jääskeläinen, Iiro P; Ahveninen, Jyrki; Andermann, Mark L; Belliveau, John W; Raij, Tommi; Sams, Mikko

2011-11-08

Based on behavioral studies, several relatively distinct perceptual and cognitive functions have been defined in cognitive psychology such as sensory memory, short-term memory, and selective attention. Here, we review evidence suggesting that some of these functions may be supported by shared underlying neuronal mechanisms. Specifically, we present, based on an integrative review of the literature, a hypothetical model wherein short-term plasticity, in the form of transient center-excitatory and surround-inhibitory modulations, constitutes a generic processing principle that supports sensory memory, short-term memory, involuntary attention, selective attention, and perceptual learning. In our model, the size and complexity of receptive fields/level of abstraction of neural representations, as well as the length of temporal receptive windows, increases as one steps up the cortical hierarchy. Consequently, the type of input (bottom-up vs. top down) and the level of cortical hierarchy that the inputs target, determine whether short-term plasticity supports purely sensory vs. semantic short-term memory or attentional functions. Furthermore, we suggest that rather than discrete memory systems, there are continuums of memory representations from short-lived sensory ones to more abstract longer-duration representations, such as those tapped by behavioral studies of short-term memory.

A short review of headspace extraction and ultrasonic solvent extraction for honey volatiles fingerprinting

Directory of Open Access Journals (Sweden)

Z. Marijanović

2009-01-01

Full Text Available Honey volatiles exhibit a potential role in distinguishing honeys as a function of botanical origin, but heating of honey generates artefacts such as compounds of Strecker degradation and Maillard reaction products. This short review is focused on the most recently applied methods for honey volatiles fingerprinting (without generation of thermal artefacts: headspace extraction (dynamic headspace extraction (DHE, headspace solid-phase microextraction (HS-SPME and ultrasonic solvent extraction (USE. These methods display a varying degree of selectivity and effectiveness depending upon the compounds involved and the extraction conditions. Recent developments of these methods are discussed, with application examples drawn from the literature as well from our own research. Flavour qualities of the honey are very much dependent on the volatile and semivolatile organic compounds present in both the sample matrix and the headspace aroma. Therefore the use of one single technique is not adequate for reliable honey volatiles profiling, but combined use of headspace extraction and ultrasonic solvent extraction could be a useful tool for the characterization of the honey and identification of its botanical source through typical volatile marker compounds.

Casticin from Vitex species: a short review on its anticancer and anti-inflammatory properties.

Science.gov (United States)

Chan, Eric Wei Chiang; Wong, Siu Kuin; Chan, Hung Tuck

2018-05-01

This short review provides an update of the anticancer and anti-inflammatory properties of casticin from Vitex species. Casticin is a polymethylflavone with three rings, an orthocatechol moiety, a double bond, two hydroxyl groups and four methoxyl groups. Casticin has been isolated from various tissues of plants in the Vitex genus: fruits and leaves of V. trifolia, aerial parts and seeds of V. agnus-castus and leaves of V. negundo. Studies have reported the antiproliferative and apoptotic activities of casticin from Vitex species. The compound is effective against many cancer cell lines via different molecular mechanisms. Studies have also affirmed the anti-inflammatory properties of casticin, with several molecular mechanisms identified. Other pharmacological properties include anti-asthmatic, tracheospasmolytic, analgesic, antihyperprolactinemia, immunomodulatory, opioidergic, oestrogenic, anti-angiogenic, antiglioma, lung injury protection, rheumatoid arthritis amelioration and liver fibrosis attenuation activities. Clinical trials and commercial use of the casticin-rich fruit extract of V. agnus-castus among women with premenstrual syndrome were briefly discussed. Copyright © 2018 Shanghai Changhai Hospital.

The Empire Mine, together with other mines in the Grass Valley mining district, produced at least 21.3 million troy ounces (663 tonnes) of gold (Au) during the 1850s through the 1950s, making it the most productive hardrock Au mining district in California history (Clark 1970). The Empire Mine State Historic Park (Empire Mine SHP or EMSHP), established in 1975, provides the public with an opportunity to see many well-preserved features of the historic mining and mineral processing operations (CDPR 2014a).A legacy of Au mining at Empire Mine and elsewhere is contamination of mine wastes and associated soils, surface waters, and groundwaters with arsenic (As), mercury (Hg), lead (Pb), and other metals. At EMSHP, As has been the principal contaminant of concern and the focus of extensive remediation efforts over the past several years by the State of California, Department of Parks and Recreation (DPR) and Newmont USA, Ltd. In addition, the site is the main focus of a multidisciplinary research project on As bioavailability and bioaccessibility led by the California Department of Toxic Substances Control (DTSC) and funded by the U.S. Environmental Protection Agency’s (USEPA’s) Brownfields Program.This chapter was prepared as a guide for a field trip to EMSHP held on June 14, 2014, in conjunction with a short course on “Environmental Geochemistry, Mineralogy, and Microbiology of Arsenic” held in Nevada City, California on June 15–16, 2014. This guide contains background information on geological setting, mining history, and environmental history at EMSHP and other historical Au mining districts in the Sierra Nevada, followed by descriptions of the field trip stops.

Integration of Jeddah Historical BIM and 3D GIS for Documentation and Restoration of Historical Monument

Science.gov (United States)

Baik, A.; Yaagoubi, R.; Boehm, J.

2015-08-01

This work outlines a new approach for the integration of 3D Building Information Modelling and the 3D Geographic Information System (GIS) to provide semantically rich models, and to get the benefits from both systems to help document and analyse cultural heritage sites. Our proposed framework is based on the Jeddah Historical Building Information Modelling process (JHBIM). This JHBIM consists of a Hijazi Architectural Objects Library (HAOL) that supports higher level of details (LoD) while decreasing the time of modelling. The Hijazi Architectural Objects Library has been modelled based on the Islamic historical manuscripts and Hijazi architectural pattern books. Moreover, the HAOL is implemented using BIM software called Autodesk Revit. However, it is known that this BIM environment still has some limitations with the non-standard architectural objects. Hence, we propose to integrate the developed 3D JHBIM with 3D GIS for more advanced analysis. To do so, the JHBIM database is exported and semantically enriched with non-architectural information that is necessary for restoration and preservation of historical monuments. After that, this database is integrated with the 3D Model in the 3D GIS solution. At the end of this paper, we'll illustrate our proposed framework by applying it to a Historical Building called Nasif Historical House in Jeddah. First of all, this building is scanned by the use of a Terrestrial Laser Scanner (TLS) and Close Range Photogrammetry. Then, the 3D JHBIM based on the HOAL is designed on Revit Platform. Finally, this model is integrated to a 3D GIS solution through Autodesk InfraWorks. The shown analysis presented in this research highlights the importance of such integration especially for operational decisions and sharing the historical knowledge about Jeddah Historical City. Furthermore, one of the historical buildings in Old Jeddah, Nasif Historical House, was chosen as a test case for the project.

Review paper. Terminal lucidity

Directory of Open Access Journals (Sweden)

Chiriboga-Oleszczak Boris Alejandro

2017-03-01

Full Text Available Terminal lucidity is a term used in the medical literature to determine the improvement of mental functioning shortly before death, even among patients with serious and long-term disorders. In 19th century, cases of mind clarity recovery shortly before death, were often recognized by doctors and interpreted as a sign of an impending death. In 20th century, the interest in this phenomenon decreased and then, virtually disappear. In recent years, on the wave of publications concerning near death experiences and related events such as the end of life experiences, papers about the improvement of mental functioning shortly before death, exponentially grew and got a new name, terminal lucidity. In this paper, an overview of the available literature is presented to outline the historical, phenomenological and clinical picture of this phenomenon and its possible implications for medical care and future studies.

Uptake and metabolism of the short-chain fatty acid butyrate, a critical review of the literature.

Science.gov (United States)

Astbury, Stuart M; Corfe, Bernard M

2012-07-01

Butyrate is a short-chain fatty acid (SCFA) formed by bacterial fermentation of fibre in the colon, and serves as an energy source for colonocytes. The action of butyrate as a histone deacetylase inhibitor (HDACi) has led to a number of clinical trials testing its effectiveness as a potential treatment for cancer. The biology of butyrate transport is therefore relevant to both its physiological and pharmacological benefits. This review of the literature was carried out to assess the evidence for both the uptake and metabolism of butyrate, in an attempt to determine possible mechanism (s) by which butyrate can act as an HDACi. It is noted that although uptake and metabolism are well characterised, there are still significant gaps in the knowledgebase around the intracellular handing of butyrate, where assumptions or dated evidence are relied upon.

Palus, S; Springer, J I; Doehner, W; von Haehling, S; Anker, M; Anker, S D; Springer, J

2017-07-01

Approximately 40-50% of the population over 80years of age suffers from sarcopenia making this condition a major geriatric clinical disorder and a key challenge to healthy aging. The hallmark symptom of sarcopenia is the loss of muscle mass and strength without the loss of overall body weight. Sarcopenic patients are likely to have worse clinical outcomes and higher mortality compared to healthy individuals. This review will focus on animal models designed to study sarcopenia including hind-limb unloading, de-nervation, and immobilization by using casts or wire strategies, as well as using aged rodents. Currently there are no registered treatments for sarcopenia. Most sarcopenic individuals show signs of physical frailty, which leads to increases the prevalence of balance disorders, falls, fractures and pain. Therefore, is it essential to develop and use relevant animal models to further the research on sarcopenia therapy? Copyright © 2017 Elsevier B.V. All rights reserved.

Assessing temporal couplings in social-ecological island systems: historical deforestation and soil loss on Mauritius (Indian Ocean

Directory of Open Access Journals (Sweden)

S.J. Norder

2017-03-01

Full Text Available Temporal couplings, such as historical interactions between deforestation and soil loss, are responsible for the current state of a wide range of ecosystem services of the social-ecological system on Mauritius. Islands are suitable study sites for understanding temporal couplings and telecouplings because of their: (1 clearly defined physical boundaries, (2 finite local resources, and (3 relatively short human history. Six well-documented historical deforestation maps, starting from the first colonization of Mauritius in 1638, were used as input parameters to model two scenarios of cumulative soil loss, with and without deforestation, using the revised universal soil loss equation in a geographic information system. The scenarios show that historical deforestation since 1638 has resulted in a cumulative soil loss that drastically exceeds soil loss under a natural baseline scenario without deforestation. The adopted method illustrates to what extent the current state of the soil of a social-ecological system is negatively affected by past human-environment interactions. We suggest that potential negative impacts on insular societies are mitigated by telecouplings such as food, fuel, and fertilizer imports.

The strong interaction of nucleons at short distances leads to a high-momentum component to the nuclear wave function, associated with short-range correlations between nucleons. These short-range, high-momentum structures in nuclei are one of the least well understood aspects of nuclear matter, relating to strength outside of the typical mean-field approaches to calculating the structure of nuclei. While it is difficult to study these short-range components, significant progress has been made over the last decade in determining how to cleanly isolate short-range correlations in nuclei. We have moved from asking if such structures exist, to mapping out their strength in nuclei and studying their microscopic structure. A combination of several different measurements, made possible by high-luminosity and high-energy accelerators, coupled with an improved understanding of the reaction mechanism issues involved in studying these structures, has led to significant progress, and provided significant new information on the nature of these small, highly-excited structures in nuclei. We review the general issues related to short-range correlations, survey recent experiments aimed at probing these short-range structures, and lay out future possibilities to further these studies.

On the Historical and Conceptual Foundations of a Community Psychology of Social Transformation.

Gokani, Ravi; Walsh, Richard T G

2017-06-01

We examine historical and conceptual literature in community psychology in order to understand the field's potential to be the socially transformative subdiscipline of psychology to which it aspires. By reviewing papers from two prominent journals and other literature, we conclude that the claim that community psychology is well-suited to social transformation, because it is a product of Sixties' radicalism and is theoretically equipped, is untenable. Systematic accounts of the subdiscipline's origins suggest that the transformative aspirations of current community psychologists do not correspond to the subdiscipline's reformist past. Furthermore, in analyzing three related concepts currently employed in the field-social justice, power, and praxis-we show that each suffers from conceptual ambiguity and a restricted political scope. These conceptual flaws, coupled with community psychology's historical inclination toward social reform, inhibit the possibility of contributing to radical social transformation. We conclude that neither questionable historical claims nor ambiguous and politically dubious concepts support a community psychology of social transformation. We offer solutions for the historical and conceptual problems we identify and, as a broader solution to the problem of engaging in socially transformative work, propose that community psychologists should seek direct political engagement in solidarity with other citizens as fellow citizens not as psychologists. © Society for Community Research and Action 2017.

Annual Energy Review 1999

Energy Technology Data Exchange (ETDEWEB)

Seiferlein, Katherine E. [USDOE Energy Information Administration (EIA), Washington, DC (United States)

2000-07-01

A generation ago the Ford Foundation convened a group of experts to explore and assess the Nation’s energy future, and published their conclusions in A Time To Choose: America’s Energy Future (Cambridge, MA: Ballinger, 1974). The Energy Policy Project developed scenarios of U.S. potential energy use in 1985 and 2000. Now, with 1985 well behind us and 2000 nearly on the record books, it may be of interest to take a look back to see what actually happened and consider what it means for our future. The study group sketched three primary scenarios with differing assumptions about the growth of energy use. The Historical Growth scenario assumed that U.S. energy consumption would continue to expand by 3.4 percent per year, the average rate from 1950 to 1970. This scenario assumed no intentional efforts to change the pattern of consumption, only efforts to encourage development of our energy supply. The Technical Fix scenario anticipated a “conscious national effort to use energy more efficiently through engineering know-how." The Zero Energy Growth scenario, while not clamping down on the economy or calling for austerity, incorporated the Technical Fix efficiencies plus additional efficiencies. This third path anticipated that economic growth would depend less on energy-intensive industries and more on those that require less energy, i.e., the service sector. In 2000, total energy consumption was projected to be 187 quadrillion British thermal units (Btu) in the Historical Growth case, 124 quadrillion Btu in the Technical Fix case, and 100 quadrillion Btu in the Zero Energy Growth case. The Annual Energy Review 1999 reports a preliminary total consumption for 1999 of 97 quadrillion Btu (see Table 1.1), and the Energy Information Administration’s Short-Term Energy Outlook (April 2000) forecasts total energy consumption of 98 quadrillion Btu in 2000. What energy consumption path did the United States actually travel to get from 1974, when the scenarios were drawn

The Historic Preservation Plan (HPP) recognizes that the Y-12 National Security Complex is a vital and long-term component of DOE and NNSA. In addition to NNSA missions, the Office of Science and Energy, the Office of Nuclear Energy, and the Office of Environmental Management have properties located at Y-12 that must be taken into consideration. The HPP also recognizes that the challenge for cultural resource management is incorporating the requirements of NNSA, SC, NE, and EM missions while preserving and protecting its historic resources. The HPP seeks to find an effective way to meet the obligations at Y-12 for historic and archeological protection while at the same time facilitating effective completion of ongoing site mission activities, including removal of obsolete or contaminated facilities, adaptive reuse of existing facilities whenever feasible, and construction of new facilities in order to meet site mission needs. The Y-12 Historic Preservation Plan (HPP) defines the preservation strategy for the Y-12 National Security Complex and will direct efficient compliance with the NHPA and federal archaeological protection legislation at Y-12 as DOE and NNSA continues mission activities of the site.

Historical and interpretative aspects of quantum mechanics: a physicists' naive approach

Directory of Open Access Journals (Sweden)

B.Berche

2006-01-01

Full Text Available Many theoretical predictions derived from quantum mechanics have been confirmed experimentally for the last 80 years. However, interpretative aspects have long been subject to debate. Among them, the question of the existence of hidden variables is still open. We review these questions, paying special attention to historical aspects, and argue that one may definitively exclude local realism based on the present experimental outcomes. Nevertheless other interpretations of Quantum Mechanics are not excluded.

After the publication of the SISRA (CERESIS-1985) regional project, a unified catalog of seismic parameters and intensities for South America, researchers in historical seismicity have continued advancing on different scales in the area of this study of seismic hazard. The most important initiatives carried out in this area in Colombia and Venezuela can be grouped as follows: a) Reviews of destructive earthquakes in national and international historic archives, principally by Altez and FUNVISIS in Venezuela and Espinosa, Salcedo, and Sarabia et al in Colombia, leading to the preparation of seismologic catalogues, scientific and dissemination articles, reports, books, among others. b) Organization and systematization of historic information to develop public domain data bases and information, specifically the Historic Seismologic Teleinformation System in Venezuela, carried out between 2004 and 2008 under the coordination of Christl Palme and accessible on-line: http://sismicidad.ciens.ula.ve. As well, the "Historia Sísmica de Colombia 1550-1830" (Seismic History in Colombia 1550-1830) data base, in CD-ROM, by Espinosa Baquero (2003) and the historic seismicity information system of Colombia (Servicio Geológico Colombiano-Universidad Nacional de Colombia), published on the internet in 2012: http://agata.ingeominas.gov.co:9090/SismicidadHistorica/. c) Macroseismic studies for the development of intensity attenuation equations and the quantification and revaluation of basic historic earthquake parameters using isoseismal maps (Rengifo et al., Palme et al., Salcedo et al., among others) and procedures such as Boxer and Bakun & Wentworth (Palme et al., Dimaté, among others), which have produced significant changes in the parameters of some of the large earthquakes. d) Symposiums of researchers to promote interest and development in the discipline, including Jornadas Venezolanas de Sismología Histórica (Venezuelan Congress of Historical Seismology), held

Urban science education: examining current issues through a historical lens

McLaughlin, Cheryl A.

2014-12-01

This paper reviews and synthesizes urban science education studies published between 2000 and 2013 with a view to identifying current challenges faced by both teachers and students in urban classrooms. Additionally, this paper considers the historical events that have shaped the conditions, bureaucracies, and interactions of urban institutions. When the findings from these urban science education studies were consolidated with the historical overview provided, it was revealed that the basic design and regulatory policies of urban schools have not substantively changed since their establishment in the nineteenth century. Teachers in urban science classrooms continue to face issues of inequality, poverty, and social injustice as they struggle to meet the needs of an increasingly diverse student population. Furthermore, persistent concerns of conflicting Discourses, cultural dissonance, and oppression create formidable barriers to science learning. Despite the many modifications in structure and organization, urban students are still subjugated and marginalized in systems that emphasize control and order over high-quality science education.

Towards short wavelengths FELs workshop

International Nuclear Information System (INIS)

Ben-Zvi, I.; Winick, H.

1993-01-01

This workshop was caged because of the growing perception in the FEL source community that recent advances have made it possible to extend FEL operation to wavelengths about two orders of magnitude shorter than the 240 nm that has been achieved to date. In addition short wavelength FELs offer the possibilities of extremely high peak power (several gigawatts) and very short pulses (of the order of 100 fs). Several groups in the USA are developing plans for such short wavelength FEL facilities. However, reviewers of these plans have pointed out that it would be highly desirable to first carry out proof-of-principle experiments at longer wavelengths to increase confidence that the shorter wavelength devices will indeed perform as calculated. The need for such experiments has now been broadly accepted by the FEL community. Such experiments were the main focus of this workshop as described in the following objectives distributed to attendees: (1) Define measurements needed to gain confidence that short wavelength FELs will perform as calculated. (2) List possible hardware that could be used to carry out these measurements in the near term. (3) Define a prioritized FEL physics experimental program and suggested timetable. (4) Form collaborative teams to carry out this program

It could be argued that one of the few unifying qualities all human beings share is the ability to appreciate beauty. While the object of beauty may change from one person to another, the awe and the thrill experienced by an enthralled beholder remains the same. Sometimes, this experience can be so overwhelming it can bring someone to the edge of existence. A very rare condition, known as aesthetic syndrome and, more commonly, Stendhal syndrome, entails a clinical phenomenon in which the presence of a beautiful piece of work or architecture causes dysautonomic symptoms such as tachycardia, diaphoresis, chest pains and loss of consciousness. We present an historical and clinical review of this condition.

A more explicit thematization of temporality in history and society would, among other things, help to clarify issues linked to the notion of path dependency.

Full Text Available A 5½-year-old adopted girl was referred to us in view of short stature. After ruling out systemic illness, she was evaluated for growth hormone deficiency (GHD by stimulation tests. The peak value was 3.47 ng/ml. She was then started on growth hormone (GH. At the end of 6 months of GH therapy, her height velocity was only 3 cm/year. There was a lack of attachment between the mother and the child. She had history of hyperphagia, stealing, and hoarding food. Psychiatry consultation confirmed that the child had appetite disorder, and hence was diagnosed as hyperphagic short stature (HSS. The girl and her parents are undergoing psychiatric therapy for the same. Psychosocial dwarfism seems to originate from serious disturbances in the mother-child relationship. These children mimic patients with GHD, but have poor response to GH therapy. This case underscores the importance of social environment in the growth of the individual.

Historical review of the List of Occupational Diseases recommended by the International Labour organization (ILO)

Science.gov (United States)

2013-01-01

The list of occupational diseases established in the international and national legal system has played important roles in both prevention of and compensation for workers’ diseases. This report reviewed the historical development in the ILO list of occupational diseases and suggested implications of the trends. Since the first establishment of the ILO list of occupational diseases in 1925, the list has played a key role in harmonizing the development of policies on occupational diseases at the international level. The three occupational diseases (anthrax, lead poisoning, and mercury poisoning) in the first ILO list of occupational diseases, set up in 1925 as workmen’s compensation convention represented an increase of occupational diseases from the Industrial Revolution. Until the 1960s, 10 occupational diseases had been representative compensable occupational diseases listed in Convention No. 121, which implies that occupational diseases in this era were equated to industrial poisoning. Since 1980, with advancements in diagnostic techniques and medical science, noise-induced hearing loss, and several bronchopulmonary diseases have been incorporated into the ILO occupational list. Since 2002, changes in the structure of industries, emerging new chemicals, and advanced national worker’s compensation schemes have provoked the ILO to revise the occupational disease list. A new format of ILO list appended in Recommendation 194 (R194) was composed of two dimensions (causes and diseases) and subcategories. Among 50 member states that had provided their national lists of occupational diseases, until 2012 thirty countries were found to have the list occupational diseases having similar structure to ILO list in R194.

A Simple Hybrid Model for Short-Term Load Forecasting

Directory of Open Access Journals (Sweden)

Suseelatha Annamareddi

2013-01-01

Full Text Available The paper proposes a simple hybrid model to forecast the electrical load data based on the wavelet transform technique and double exponential smoothing. The historical noisy load series data is decomposed into deterministic and fluctuation components using suitable wavelet coefficient thresholds and wavelet reconstruction method. The variation characteristics of the resulting series are analyzed to arrive at reasonable thresholds that yield good denoising results. The constitutive series are then forecasted using appropriate exponential adaptive smoothing models. A case study performed on California energy market data demonstrates that the proposed method can offer high forecasting precision for very short-term forecasts, considering a time horizon of two weeks.

2000-01-01

Backfills have been part of Sandia National Laboratories' [Sandia's] Waste Isolation Pilot Plant [WIPP] designs for over twenty years. Historically, backfill research at Sandia has depended heavily on the changing mission of the WIPP facility. Early testing considered heat producing, high level, wastes. Bentonite/sand/salt mixtures were evaluated and studies focused on developing materials that would retard brine ingress, sorb radionuclides, and withstand elevated temperatures. The present-day backfill consists of pure MgO [magnesium oxide] in a pelletized form and is directed at treating the relatively low contamination level, non-heat producing, wastes actually being disposed of in the WIPP. Its introduction was motivated by the need to scavenging CO 2 [carbon dioxide] from decaying organic components in the waste. However, other benefits, such as a substantial desiccating capacity, are also being evaluated. The MgO backfill also fulfills a statutory requirement for assurance measures beyond those needed to demonstrate compliance with the US Environmental Protection Agency [EPA] regulatory release limits. However, even without a backfill, the WIPP repository design still operates within EPA regulatory release limits

Short-term mechanical circulatory support (MCS) is increasingly used as a bridge to decision in patients with refractory cardiogenic shock. Subsequently, these patients might be bridged to durable MCS either as a bridge to candidacy/transplantation, or as destination therapy. The aim of this study was to review support duration and clinical outcome of short-term MCS in cardiogenic shock, and to analyse application of this technology as a bridge to long-term cardiac support (left ventricular assist device, LVAD) from 2006 till June 2016. Using Cochrane Register of Trials, Embase and Medline, a systematic review was performed on patients with cardiogenic shock from acute myocardial infarction, end-stage cardiomyopathy, or acute myocarditis, receiving short-term MCS. Studies on periprocedural, post-cardiotomy and cardiopulmonary resuscitation support were excluded. Thirty-nine studies, mainly registries of heterogeneous patient populations (n = 4151 patients), were identified. Depending on the device used (intra-aortic balloon pump, TandemHeart, Impella 2.5, Impella 5.0, CentriMag and peripheral veno-arterial extracorporeal membrane oxygenation), mean support duration was (range) 1.6-25 days and the mean proportion of short-term MCS patients discharged was (range) 45-66%. The mean proportion of bridge to durable LVAD was (range) 3-30%. Bridge to durable LVAD was most frequently performed in patients with end-stage cardiomyopathy (22 [12-35]%). We conclude that temporary MCS can be used to bridge patients with cardiogenic shock towards durable LVAD. Clinicians are encouraged to share their results in a large multicentre registry in order to investigate optimal device selection and best duration of support. © The Author 2017.

Integration of Jeddah Historical BIM and 3D GIS for Documentation and Restoration of Historical Monument

Directory of Open Access Journals (Sweden)

A. Baik

2015-08-01

Full Text Available This work outlines a new approach for the integration of 3D Building Information Modelling and the 3D Geographic Information System (GIS to provide semantically rich models, and to get the benefits from both systems to help document and analyse cultural heritage sites. Our proposed framework is based on the Jeddah Historical Building Information Modelling process (JHBIM. This JHBIM consists of a Hijazi Architectural Objects Library (HAOL that supports higher level of details (LoD while decreasing the time of modelling. The Hijazi Architectural Objects Library has been modelled based on the Islamic historical manuscripts and Hijazi architectural pattern books. Moreover, the HAOL is implemented using BIM software called Autodesk Revit. However, it is known that this BIM environment still has some limitations with the non-standard architectural objects. Hence, we propose to integrate the developed 3D JHBIM with 3D GIS for more advanced analysis. To do so, the JHBIM database is exported and semantically enriched with non-architectural information that is necessary for restoration and preservation of historical monuments. After that, this database is integrated with the 3D Model in the 3D GIS solution. At the end of this paper, we’ll illustrate our proposed framework by applying it to a Historical Building called Nasif Historical House in Jeddah. First of all, this building is scanned by the use of a Terrestrial Laser Scanner (TLS and Close Range Photogrammetry. Then, the 3D JHBIM based on the HOAL is designed on Revit Platform. Finally, this model is integrated to a 3D GIS solution through Autodesk InfraWorks. The shown analysis presented in this research highlights the importance of such integration especially for operational decisions and sharing the historical knowledge about Jeddah Historical City. Furthermore, one of the historical buildings in Old Jeddah, Nasif Historical House, was chosen as a test case for the project.

Historical review: Does falciparum malaria destroy isolated tribal populations?

Science.gov (United States)

Shanks, G Dennis

Many isolated populations of tribal peoples were nearly destroyed when they first contacted infectious diseases particularly respiratory pathogens such as measles and smallpox. Surviving groups have often been found to have declining populations in the face of multiple social and infectious threats. Malaria, especially Plasmodium falciparum, was thought to be a major cause of depopulation in some tribal peoples isolated in tropical jungles. The dynamics of such host parasite interactions is unclear especially since most such populations would have had long histories of exposure to malaria. Three groups are individually reviewed: Meruts of Borneo, Yanomami of Amazonia, Jarawas of the Andaman Islands. The purpose of this review is to examine the role of falciparum malaria in the depopulation of some isolated tribal groups in order to understand what measures, if any, would be likely to prevent such losses.

The Work Accidents and Occupational Diseases Act exists in Chile since 1968. It uses a single model for the understanding and management of both somatic diseases like silicosis and psychiatric disorders. During the last decade in Chile, the consultation rates due to psychiatric conditions of probable labor origin has rose over 1,000%, a factor that underscored the deficiencies of this model. The aim of this paper is to analyze the consequences of the application of this act in the psychiatric field for almost 50 years after its promulgation. This article contains an historical overview and an epistemological debate based on the authors’ experience dealing with clinical and administrative work both in occupational psychiatry departments and in regulatory entities. The development of occupational mental health in Chile is examined as part of an historical process that initially did not consider the relationship between work and mental suffering as relevant. The application of a single causality model in psychiatry, as well as the effects of building a psychiatric nosology upon legal rather than medical criteria is contested.

Prescribed fire is widely accepted as a conservation tool because fire is essential to the maintenance of native biodiversity in many terrestrial communities. Approaches to this land-management technique vary greatly among continents, and sharing knowledge internationally can inform application of prescribed fire worldwide. In North America, decisions about how and when to apply prescribed fire are typically based on the historical-fire-regime concept (HFRC), which holds that replicating the pattern of fires ignited by lightning or preindustrial humans best promotes native species in fire-prone regions. The HFRC rests on 3 assumptions: it is possible to infer historical fire regimes accurately; fire-suppressed communities are ecologically degraded; and reinstating historical fire regimes is the best course of action despite the global shift toward novel abiotic and biotic conditions. We examined the underpinnings of these assumptions by conducting a literature review on the use of historical fire regimes to inform the application of prescribed fire. We found that the practice of inferring historical fire regimes for entire regions or ecosystems often entails substantial uncertainty and can yield equivocal results; ecological outcomes of fire suppression are complex and may not equate to degradation, depending on the ecosystem and context; and habitat fragmentation, invasive species, and other modern factors can interact with fire to produce novel and in some cases negative ecological outcomes. It is therefore unlikely that all 3 assumptions will be fully upheld for any landscape in which prescribed fire is being applied. Although the HFRC is a valuable starting point, it should not be viewed as the sole basis for developing prescribed fire programs. Rather, fire prescriptions should also account for other specific, measurable ecological parameters on a case-by-case basis. To best achieve conservation goals, researchers should seek to understand contemporary fire

Ophthalmology's future in the next decade: a historical and comparative perspective.

Day, S H

To gain a historical and comparative perspective about the future of ophthalmology within the profession of medicine. A literature search is made of disciplines other than medicine (history, sociology, philosophy, economics, and ethics) in order to assess factors responsible for survival and healthiness of a profession. The "learned" professions (medicine, law, and theology) are assessed. Other "professional" careers valued by society (sports and classical music) are reviewed. From the perspective of other disciplines, the future of ophthalmology is seen as vulnerable and fragile. Survival of professions, be they classically or economically defined, is linked to societal needs, a profession's unique commitment and ability to provide services to society, and the profession's maintenance of knowledge as well as skill-based services. Historical evidence has shown erosion of a profession's power consequent to capitalist influences, government influences, access of skills by less trained individuals, and elitist posturing by a profession. Comparative evidence has shown societal acceptance of an escalation of salaries for designated superstars, increasing roles and influence of managerial personnel, and trivialization of values other than economic ones. Attention to historical and comparative trends by individual ophthalmologists as well as associations representing ophthalmologists is mandatory if ophthalmology as we know it is to survive within the profession of medicine.

Alloplastic temporomandibular joint replacement systems: a systematic review of their history.

This systematic review provides an overview of the historical evolution of the prosthetic temporomandibular joint and addresses the challenges and complications faced by engineers and surgeons, in an effort to shed light on why only a few systems remain available. A better understanding of the history of temporomandibular joint prostheses might also provide insights into the origin of the negative public opinion of the prosthesis, which is based on outdated information. A computerized search using the PubMed Central, ScienceDirect, Wiley Online, Ovid, and Cochrane Library databases was performed following the PRISMA guidelines. Out of 7122 articles identified, 41 met the inclusion criteria for this systematic review. Although several historical reviews have been published previously, none has covered such an extensive time period or has described all designs. Furthermore, besides providing a historical overview, this review discusses the rationale behind the evolution in design and biomaterials, which have largely contributed to the outcomes of the prosthetic systems.

Full Text Available The article determines the importance of long-term and short-term liabilities for the management of financial and material resources of an enterprise. It reviews the aim, objects and information generators for realization of audit of short-term and long-term obligations. The organizing and methodical providing of audit of long-term and short-term liabilities of an enterprise are generalized. The authors distinguish the stages of realization of audit of long-term and short-term liabilities, the aim of audit on each of the presented stages, and recommend methodical techniques. It is fixed that it is necessary to conduct the estimation of the systems of internal control and record-keeping of an enterprise by implementation of public accountant procedures for determination of volume and maintenance of selection realization. After estimating the indicated systems, a public accountant determines the methodology for realization of public accountant verification of long-term and short-term liabilities. The analytical procedures that public accountants are expedient to use for realization of audit of short-term and long-term obligations are determined. The authors suggest the classification of the educed defects on the results of the conducted public accountant verification of short-term and long-term obligations.

Full Text Available In order to prolong the life of the old buildings in the country through building conservation practices, there is a tendency by the government to acquire and reuse Malaysian leadership figures’ residential buildings as memorials. However, it raises the question of whether there is any adaptive reuse guidelines to reuse historic residential buildings in Malaysia as national memorials in maintaining those buildings as an exhibition space on the history of their leadership. The absence of guidelines raises questions about how to implement the process accordingly. The objective of this research is to find the best formula for reusing historic residential buildings as national memorials based on that issue by reviewing and identify the principles of adaptive reuse practices of historic residential buildings as national memorials that implemented in Malaysia. The case studies were conducted on three samples of historic residential buildings that reused as national memorials and those buildings were selected based on a list of the study population, which are Rumah Kelahiran Tun Dr. Mahathir Mohamad (The Birthplace of Tun Dr. Mahathir Mohamad, Rumah Merdeka (Freedom House and Memorial Tun Abdul Ghafar Baba (The Tun Abdul Ghafar Baba Memorial. The sample may be determined by the sampling method and evaluated using the checklist provided. Based on the results of the case studies that were analyzed and discussed, it can be concluded that aspects of building code (local requirements as well as environmental and conservation requirements are not met in implementing adaptive reuse process on historic residential buildings to national memorials which needs suggestions for improvement.

Full Text Available This text presents a study of historical-critical pedagogy and cultural-historical psychology and its goal is to show the theoretical approach that exists between them and their contributions to the school education. This interest appeared as soon as we could see that these two concepts are present in academic publications and productions that discuss school and educational work, however some aspects are still not very clear for the educators who follow this line of thought. So, we organized the text in a way that clarifies that dialectical and historical materialism as a philosophical principle, covers these two theories allowing, in the educational field, they can be adopted as a benchmark for the development of educational work.

Assessing historical empathy through simulation – How do Finnish teacher students achieve contextual historical empathy?

Full Text Available There has been a great deal of international debate about introducing historical empathy as the focus in teaching history. However, as it is, the contents of the concept have been included in the curricula in many countries. Nevertheless, practising stepping into the shoes of a person from a previous era is still in its infancy in schools in many locations – Finland included. This article discusses Finnish class teacher students' understanding of historical empathy. The article is based on a study where 360 class teacher students played a game simulating the Cuban Missile Crisis. Their task was to assume the roles of the superpower leaders and make decisions on the basis of these roles. The simulation showed that a majority of the student teachers are able to attain a level of contextual historical empathy. They were able to empathize with the historical context in question and make such decisions that would have been possible for the historical actors. Some of the playing groups on the other hand, referred to their current knowledge and attitudes, which, according to Ashby and Lee's empathy classification, shows lower-level empathy. The study corroborates previous research results concerning great discrepancies in the understanding of empathy prevalent within one age group. Moreover, the study raises the question of how historical empathy should be handled in teaching if many future teachers have difficulties in understanding it.

During the past three decades, improvements in the treatment of childhood leukemia have resulted in high cure rates, particularly for acute lymphoblastic leukemia (ALL). Unfortunately, successful therapy has come with a price, as significant morbidity can result from neurological affects which harm the brain and spinal cord. The expectation and hope is that chemotherapy, as a primary means of CNS therapy, will result in acceptable disease control with less CNS morbidity than has been observed with combinations of chemotherapy and radiotherapy over the past several decades. In this review we discuss the poignant, historical aspects of CNS leukemia therapy, outline current methods of systemic and CNS leukemia therapy, and present imaging findings we have encountered in childhood leukemia patients with a variety of acute neurological conditions. A major objective of our research is to understand the neuroimaging correlates of acute and chronic effects of cancer and therapy. Specific features related to CNS leukemia and associated short-term toxicities, both disease- and therapy-related, are emphasized in this review with the specific neuroimaging findings. Specific CNS findings are similarly important when treating acute myelogenous leukemia (AML), and details of leukemic involvement and toxicities are also presented in this entity. Despite contemporary treatment approaches which favor the use of chemotherapy (including intrathecal therapy) over radiotherapy in the treatment of CNS leukemia, children still occasionally experience morbid neurotoxicity. Standard neuroimaging is sufficient to identify a variety of neurotoxic sequelae in children, and often suggest specific etiologies. Specific neuroimaging findings frequently indicate a need to alter antileukemia therapy. It is important to appreciate that intrathecal and high doses of systemic chemotherapy are not innocuous and are associated with acute, specific, recognizable, and often serious neurological
