    Medicine counterfeiting is a current problem that the whole pharmaceutical field has to deal with. In 2014, counterfeits entered the legitimate supply chain in Europe. Quick and efficient action had to be taken. The aim of this paper is to explain which analytical strategy was chosen to deal with six of the cases concerned and which criteria have to be considered to provide quick and thorough information about the counterfeits. The evaluation of the packaging was performed in a first step, based on a comparison with genuine samples and evaluation of manipulation signs. Chemical methods were then used, consisting of near infrared and infrared spectroscopy, capillary zone electrophoresis and ultraviolet-visible spectrophotometry, in order to authenticate the samples and provide the chemical composition of the confirmed counterfeits. Among the 20 samples analyzed, 17 were confirmed as counterfeits. The counterfeits were the results of the manipulation of genuine samples, and one contained totally counterfeited parts. Several manipulation signs were asserted, like the addition of glue on the boxes and the vials. Genuine stolen goods had been diluted with water, while for an isolated case, a different active ingredient had been introduced in a vial. The analytical data generated were further investigated from a forensic intelligence perspective. Links could be revealed between the analyzed counterfeits, together with some interesting information about the modus operandi of the counterfeiters. The study was performed on a limited number of cases, and therefore encourages chemical and packaging profiling of counterfeits at a bigger scale. Copyright © 2015 John Wiley & Sons, Ltd.

    This case study illustrates the use of a long-term integrative psychotherapy approach with a middle- aged man with chronic schizophrenia and a mood disorder. The case of "Holst" describes a man with a history of insecure attachment and trauma who later went on to contract a serious chronic illness, precipitating the onset of psychotic symptoms, depression, and chronic suicidal ideation, resulting in multiple hospitalizations. Combining metacognition-oriented therapy with elements of cognitive behavioral therapy and psychiatric rehabilitation, this approach fostered significantly improved community functioning and attainment of personal goals over time. Through the journey of therapy, the patient also developed a more coherent narrative about his life, established a stable sense of self, and became an active agent in the world. This case illustration demonstrates that these three different approaches can be used in a sequential and complementary fashion to foster recovery in the midst of serious physical and mental illness.

  6. Towards a Real Estate Registry 3d Model in Portugal: Some Illustrative Case Studies

    2013-09-01

    The 3D concept emerged as a key concept within geoinformation science. 3D geoinformation has been proved to be feasible and its added value over 2D geoinformation is widely acknowledged by researchers from various fields. Even so, 3D concept merits still need to be exploited further and more specific applications and associate products are needed - such as within real estate cadastre, our ultimate field of interest. The growing densification of urban land use is consequently increasing situations of vertical stratification of ownership rights. Traditional 2D cadastral models are not able to fully handle spatial information on those rights in the third dimension. Thus, 3D cadastre has been attracting researchers to better register and spatially represent real world overlapping situations. A centralised distributed cadastral management system, implementing a 2D cadastral model, has been conceived by the national cadastral agency in Portugal: the so-called SiNErGIC. The authors seek to show with this paper that there is room though for further investigation on the suitability of a 3D modelling approach instead, which should not be confined only to topologicalgeometric representations but should also be extended in order to be able to incorporate the legal/administrative component. This paper intends to be the first step towards the design of a prototype of a 3D cadastral model capable of handling the overall multipurpose cadastral reality in Portugal; it focuses primarily on the clear identification of some case studies that may illustrate the pertinence of such an approach in the context of this country.

The paper shows how the aim and context of a study leads to an Internet research approach and how the online study was conducted, the methods that were used, the results it gave and thus also sketches the possibilities and future of Internet research.

  9. A simple insightful approach to investigating a hospital standardised mortality ratio: an illustrative case-study.

    Mohammed A Mohammed

    Full Text Available BACKGROUND: Despite methodological concerns Hospital Standardised Mortality Ratios (HSMRs are promoted as measures of performance. Hospitals that experience an increase in their HSMR are presented with a serious challenge but with little guidance on how to investigate this complex phenomenon. We illustrate a simple penetrating approach. METHODS: Retrospective analysis of routinely collected hospital admissions data comparing observed and expected deaths predicted by the Dr Foster Unit case mix adjustment method over three years (n = 74,860 admissions in Shropshire and Telford NHS Trust Hospital (SaTH constituting PRH (Princess Royal Hospital and RSH (Royal Shrewsbury Hospital; whose HSMR increased from 99 in the year 2008/09 to 118 in the year 2009/10. RESULTS: The step up in HSMR was primarily located in PRH (109 to 130 vs. 105 to 118 RSH. Disentangling the HSMR by plotting run charts of observed and expected deaths showed that observed deaths were stable in RSH and PRH but expected deaths, especially at PRH, had fallen. The fall in expected deaths has two possible explanations-genuinely lower risk admissions or that the case-mix adjustment model is underestimating the risk of admissions perhaps because of inadequate clinical coding. There was no evidence that the case-mix profile of admissions had changed but there was considerable evidence that clinical coding process at PRH was producing a lower depth of coding resulting in lower expected mortality. CONCLUSION: Knowing whether the change (increase/decrease in HSMR is driven by the numerator or the denominator is a crucial pivotal first step in understanding a given HSMR and so such information should be an integral part of the HSMR reporting methodology.

    Counterfeit pesticides threaten public health, food trade, and the environment. The present work draws attention to the importance of regular monitoring of impurities in formulated pesticide products. General screening revealed the presence of carbaryl as a contaminant in a copper oxychloride formulated product. In this paper, as a case study, a liquid chromatographic diode array-mass spectrometric method developed for general screening of pesticide products and quantitative determination of carbaryl together with its validation is presented. The proposed testing strategy is considered suitable for use as a general approach for testing organic contaminants and impurities in solid pesticide formulations. PMID:25360991

  12. The climate impact of travel behavior: A German case study with illustrative mitigation options

    International Nuclear Information System (INIS)

    Highlights: • We estimate the climate impact of German travel behavior. • The climate impact is equally dominated by car and air transport. • The rich have the largest impacts, but the larger middle class has a greater share. • A few long trips by air are responsible for a large share of the total climate impact. • A comprehensive mitigation is needed covering technology and behavioral changes. -- Abstract: Global greenhouse gas mitigation should include the growing share of emissions from transportation. To help understand the mitigation potential of changing travel behavior requires disaggregating the climate impacts of transportation by transport mode, distance, and travel behavior. Here we use disaggregated data on travel behavior to calculate the climate impact of Germans traveling nationally and internationally in 2008 and develop some illustrative mitigation options. We include all relevant long-lived greenhouse gases and short-lived climate forcers and use global temperature change for 50 years of sustained emissions as the emission metric. The total climate impact is determined almost entirely by car (∼46%) and air travel (∼45%), with smaller contributions from public transportation. The climate impact from the highest income group is 250% larger than from the lowest income group. However, the middle classes account for more than two thirds of the total impact. The relatively few trips beyond 100 km contribute more than half of the total impact because of the trip distance and use of aircraft. Individual behavioral changes, like shifting transport modes or reducing distance and frequency, can lead to useful emission reductions. However, a comprehensive package of mitigation options is necessary for deep and sustained emission reductions

  13. Radiation Recall Reaction: Two Case Studies Illustrating an Uncommon Phenomenon Secondary to Anti-Cancer Agents

    International Nuclear Information System (INIS)

    Radiation recall phenomenon is a tissue reaction that develops throughout a previously irradiated area, precipitated by the administration of certain drugs. Radiation recall is uncommon and easily neglected by physicians; hence, this phenomenon is underreported in literature. This manuscript reports two cases of radiation recall. First, a 44-year-old man with nasopharyngeal carcinoma was treated with radiotherapy in 2010 and subsequently developed multi-site bone metastases. A few days after the docetaxel-based chemotherapy, erythema and papules manifested dermatitis, as well as swallowing pain due to pharyngeal mucositis, developed on the head and neck that strictly corresponded to the previously irradiated areas. Second, a 19-year-old man with recurrent nasal NK/T cell lymphoma initially underwent radiotherapy followed by chemotherapy after five weeks. Erythema and edema appeared only at the irradiated skin. Both cases were considered chemotherapeutic agents that incurred radiation recall reactions. Clinicians should be knowledgeable of and pay attention to such rare phenomenon

    Full Text Available Purpose: Existing frameworks for understanding and analyzing the value configuration and structuring of partnerships in relation such network-based business models are found to be inferior. The purpose of this paper is therefore to broaden our understanding of how business models may change over time and how the role of strategic partners may differ over time too. Design/methodology/approach: A longitudinal case study spanning over years and mobilising multiple qualitative methods such as interviews, observation and participative observation forms the basis of the data collection. Findings: This paper illustrates how a network-based business model arises and evolves and how the forces of a network structure impact the development of its partner relationships. The contribution of this article is to understanding how partners positioned around a business model can be organized into a network-based business model that generates additional value for the core business model and for both the partners and the customers. Research limitations/implications: The results should be taken with caution as they are based on the case study of a single network-based business model. Practical implications: Managers can gain insight into barriers and enablers relating to different types of loose organisations and how to best manage such relationships and interactions Originality/value: This study adds value to the existing literature by reflecting the dynamics created in the interactions between a business model’s strategic partners and how a how a business model can evolve in a series of distinct phases

    This study discusses possibilities of using trigeneration in industrial power plant applications. The objective of this study is to compare trigeneration combined heat and power with compression chillers and separate production in terms of primary energy consumption and CO2 emissions. Some economic factors are also considered. The study focuses on the process industry, and two cases from different industrial sectors are presented. These sectors are food processing and mechanical pulp and paper. The results show that trigeneration can reduce emissions and operating costs compared with the separate production of heating and cooling. The amount of these savings is strongly dependent on the emission factor of the grid electricity replaced by trigeneration.

  17. Chilean blue whales as a case study to illustrate methods to estimate abundance and evaluate conservation status of rare species.

    Often abundance of rare species cannot be estimated with conventional design-based methods, so we illustrate with a population of blue whales (Balaenoptera musculus) a spatial model-based method to estimate abundance. We analyzed data from line-transect surveys of blue whales off the coast of Chile, where the population was hunted to low levels. Field protocols allowed deviation from planned track lines to collect identification photographs and tissue samples for genetic analyses, which resulted in an ad hoc sampling design with increased effort in areas of higher densities. Thus, we used spatial modeling methods to estimate abundance. Spatial models are increasingly being used to analyze data from surveys of marine, aquatic, and terrestrial species, but estimation of uncertainty from such models is often problematic. We developed a new, broadly applicable variance estimator that showed there were likely 303 whales (95% CI 176-625) in the study area. The survey did not span the whales' entire range, so this is a minimum estimate. We estimated current minimum abundance relative to pre-exploitation abundance (i.e., status) with a population dynamics model that incorporated our minimum abundance estimate, likely population growth rates from a meta-analysis of rates of increase in large baleen whales, and two alternative assumptions about historic catches. From this model, we estimated that the population was at a minimum of 9.5% (95% CI 4.9-18.0%) of pre-exploitation levels in 1998 under one catch assumption and 7.2% (CI 3.7-13.7%) of pre-exploitation levels under the other. Thus, although Chilean blue whales are probably still at a small fraction of pre-exploitation abundance, even these minimum abundance estimates demonstrate that their status is better than that of Antarctic blue whales, which are still <1% of pre-exploitation population size. We anticipate our methods will be broadly applicable in aquatic and terrestrial surveys for rarely encountered species

    2006-01-01

    Full Text Available We describe a novel, testable theory of autoimmunity, outline novel predictions made by the theory, and illustrate its application to unravelling the possible causes of idiopathic thrombocytopenia purpura (ITP. Pairs of stereochemically complementary antigens induce complementary immune responses (antibody or T-cell that create loss of regulation and civil war within the immune system itself. Antibodies attack antibodies creating circulating immune complexes; T-cells attack T-cells creating perivascular cuffing. This immunological civil war abrogates the self-nonself distinction. If at least one of the complementary antigens mimics a self antigen, then this unregulated immune response will target host tissues as well. Data demonstrating that complementary antigens are found in some animal models of autoimmunity and may be present in various human diseases, especially ITP, are reviewed. Specific mechanisms for preventing autoimmunity or suppressing existing autoimmunity are derived from the theory, and critical tests proposed. Finally, we argue that Koch's postulates are inadequate for establishing disease causation for multiple-antigen diseases and discuss the possibility that current research has failed to elucidate the causes of human autoimmune diseases because we are using the wrong criteria.

    Full Text Available In this communication, we report the case of a four year old boy who presented with reduced vision in the right eye. He had visual acuity of light perception right eye and 6/12 in the left eye and anterior segment examination was normal. Fundus examination of the right eye showed a falciform retinal fold extending from the optic nerve temporally involving the entire retina with exudates within the falciform fold and dense pigmentation peripherally. The left eye showed mild macular temporal dragging of the vessels and 360° of peripheral laser scars. In addition he also had some characteristic systemic features such as developmental delay, obesity, dysmorphic facies and tapered fingers. Using this case as an example, we present a systematic, logical approach to a patient with a possible genetic disorder. The growing field of ocular genetics now allows for improved diagnosis using step-wise cost efficient testing as demonstrated herein.

    Full Text Available In the current climate of dramatic advances in the neurosciences, it has been widely assumed that the diagnosis of mental disorder is a matter exclusively for value-free science. Starting from a detailed case history, this paper describes how, to the contrary, values come into the diagnosis of mental disorders, directly through the criteria at the heart of psychiatry's most scientifically grounded classification, the American Psychiatric Association's DSM (Diagnostic and Statistical Manual. Various possible interpretations of the prominence of values in psychiatric diagnosis are outlined. Drawing on work in the Oxford analytic tradition of philosophy, it is shown that, properly understood, the prominence of psychiatric diagnostic values reflects the necessary engagement of psychiatry with the diversity of individual human values. This interpretation opens up psychiatric diagnostic assessment to the resources of a new skills-based approach to working with complex and conflicting values (also derived from analytic philosophy called 'values-based practice.' Developments in values-based practice in training, policy and research in mental health are briefly outlined. The paper concludes with an indication of how the integration of values-based with evidence-based approaches provides the basis for psychiatric practice in the twenty-first century that is both science-based and person-centred.

  3. The evolution of the paleomagnetic fold test as applied to complex geologic situations, illustrated by a case study from northern Spain

    Science.gov (United States)

    Weil, Arlo B.; Van der Voo, Rob

    Paleomagnetic results are most useful if the age of the magnetization can be established with respect to the rock age or the age of specific structural or alteration events. The fold test is a particularly powerful tool; not only can it be used to determine whether magnetizations are pre-, syn- or post-folding, but it can also reassure us that structural corrections need (or need not) be applied to a given magnetization. This study traces the evolution of various fold and tilt tests developed in the 50-some years since the classical test of Graham was published. Syn-deformational magnetizations are a very special case, usually characterized as such by an incremental tilt test. In regions where rotations about (near-) vertical axes are to be expected, a strike test is the best tool for determining them. A case study of syn-deformational magnetizations in the Cantabria-Asturias Arc (CAA) of northern Spain is presented, which illustrates the application of the various tilt and strike tests. One ancient post-deformational and two syn-deformational magnetizations have been recorded in CAA Devonian carbonates, each characterized by different optimal (peak) percentages of unfolding in incremental fold tests. The structural corrections required to bring the individual site-mean magnetization directions into alignment can be used to restore the beds to their attitudes at the times when the magnetizations were acquired. Furthermore, these structural corrections provide robust constraints on the kinematics of the deformation phase that is being removed. In the CAA, removal of late-stage folding about steeply inclined fold axes, due to Permian oroclinal bending, restores the belt to its first folding and thrusting configuration, and produces north-south trending cylindrical folds that formed during the Late Carboniferous. The separate deformations, consisting of earlier folding and thrusting and later oroclinal bending, have implications for the final collisional movements

  4. Case Report: Macrodystrophia lipomatosa – Illustration of two cases

    International Nuclear Information System (INIS)

    Macrodystrophia lipomatosa is a rare cause of congenital macrodactyly, characterized by progressive proliferation of all mesenchymal elements, with a disproportionate increase in fibroadipose tissue. This developmental anomaly is reportedly more common in the foot than in the hand, with a predilection for the plantar and median nerve distribution. We present two cases of MDL of the hand, one of which had an unusual nerve territory distribution, making clinical diagnosis difficult. Preoperative diagnosis was however made on the basis of radiography and MRI and was later confirmed on surgery

  5. The use of electron Rutherford backscattering to characterize novel electronic materials as illustrated by a case study of sputter-deposited NbOx films

    International Nuclear Information System (INIS)

    Electrons scattered over large angles at relatively high energies (40 keV) are used to study NbOx films. These films were deposited by reactive sputter deposition on a Si substrate using a Nb target and an Ar/O2 gas mixture. Energy spectra of electrons scattered from such samples exhibit elastic scattering peaks for each component due to the energy difference associated with scattering from different masses. The spectra provide in this way information about the film thickness as well as its stoichiometry. The stoichiometry and the deposition rate depends on the concentration of O2 in the mixture. For Nb2O5-like films the energy loss measurements also give an estimate of the band gap, but for Nb films with lower O concentration the band gap is not resolved. This work illustrates the possibility of characterizing modern transition metal oxide films in a fairly simple electron scattering experiment

  6. Orthognathic Surgery: Planning and treatment with illustration on six cases

    International Nuclear Information System (INIS)

    Almost all conferences for plastic and maxillofacial surgery discuss reports on several methods of orthognathic surgery, planning, success results, and complications of the different procedures carried out to correct patient's soft and hard tissues frontal profiles and occlusal discrepancies. Various principles are involved in the diagnosis and treatment of facial deformities. However, the most important consideration, after all, is the final accepted aesthetic and functional requirements and stability of the moved segments. The objective of this paper is to give the basic principles of treatment planning for correcting facial discrepancies, surgical approach to different cases, and the methods to increase stability of the moved segments. Six cases are included to illustrate the different aspects of treatment planning, surgical management, and stabilization methods. (author)

    Large capital requirements needed for many agricultural businesses to operate result in many relying on borrowed funds. Fixed repayment commitments combined with a leveraged financial condition and volatile commodity prices result in increased emphasis on managing risks. Deterioration in the financial condition of an agricultural business is used to illustrate development of a risk management plan by a farm manager and his lender. The case study approach is used to initiate discussion, genera...

  11. Osteofibrous dysplasia of the proximal tibia: an illustrative case report

    Directory of Open Access Journals (Sweden)

    2015-06-01

    Full Text Available A 5 years old girl presented 3 years back with pain and swelling over the upper right leg for 2 years duration. X-ray, CT and MRI revealed osteolytic well defined lesion 2.5 and times; 2 cm in the meta-diaphyseal region of the proximal tibia with pathological fracture of anterolateral cortex. Child underwent thorough curettage of the lesion and the defect was filled with allograft (iliac crest graft from mother which was harvested in an adjacent operation theatre. The limb was protected with a plaster splint for a period of 3 months. The graft gradually consolidated and new bone formation was apparent by 6 months. Remodelling of the medullary canal occurred at 1 year follow up. Child has been followed up to 3 years (till date and there is no evidence of recurrence. The case illustrates that osteofibrous dyplasia can be effectively treated by curettage and replacement of defect by allograft from parents. [Int J Res Med Sci 2015; 3(6.000: 1518-1520

    Human effects on estuaries are often associated with major decreases in abundance of aquatic species. However, remediation priorities are difficult to identify when declines result from multiple stressors with interacting sublethal effects. The San Francisco Estuary offers a useful case study of the potential role of contaminants in declines of organisms because the waters of its delta chronically violate legal water quality standards; however, direct effects of contaminants on fish species are rarely observed. Lack of direct lethality in the field has prevented consensus that contaminants may be one of the major drivers of coincident but unexplained declines of fishes with differing life histories and habitats (anadromous, brackish, and freshwater). Our review of available evidence indicates that examining the effects of contaminants and other stressors on specific life stages in different seasons and salinity zones of the estuary is critical to identifying how several interacting stressors could contribute to a general syndrome of declines. Moreover, warming water temperatures of the magnitude projected by climate models increase metabolic rates of ectotherms, and can hasten elimination of some contaminants. However, for other pollutants, concurrent increases in respiratory rate or food intake result in higher doses per unit time without changes in the contaminant concentrations in the water. Food limitation and energetic costs of osmoregulating under altered salinities further limit the amount of energy available to fish; this energy must be redirected from growth and reproduction toward pollutant avoidance, enzymatic detoxification, or elimination. Because all of these processes require energy, bioenergetics methods are promising for evaluating effects of sublethal contaminants in the presence of other stressors, and for informing remediation. Predictive models that evaluate the direct and indirect effects of contaminants will be possible when data become

  13. The economics of pressure relieving surfaces: an illustrative case study of the impact of high-specification surfaces on hospital finances.

    Science.gov (United States)

    Trueman, Paul; Whitehead, Sarah J

    2010-02-01

    Pressure ulcers are associated with a significant economic burden that, in many cases, is recognised as being avoidable. The effectiveness of pressure relieving surfaces is well documented and acknowledged in clinical guidelines on the prevention and management of pressure ulcers. Whilst pressure relieving surfaces are more expensive than traditional hospital mattresses, judicious use, targeted to patients most at risk, can help to reduce the incidence and costs of pressure ulcers in hospital settings. This review paper includes a summary of pivotal clinical evidence on pressure relieving surfaces as well as a suggested approach for modelling their financial impact on hospital budgets. Simple financial modelling suggests that pressure relieving surfaces could lead to financial savings for a hospital when used appropriately. PMID:20409250

  14. Joubert Syndrome: Imaging Features and Illustration of a Case

    International Nuclear Information System (INIS)

    Joubert Syndrome (JS) is a rare autosomal recessive disorder characterised clinically by neonatal breathing dysregulation, developmental delay, intellectual disability, hypotonia, ataxia, nystagmus. We present another case of this uncommon syndrome in a 12 years old patient presenting with classical complaints of developmental delay, intellectual impairment, weakness in both lower limbs, ataxia and abnormal facies and diagnosed on Computed Tomography. Joubert Syndrome should be ruled out in all patients presenting with hypotonia, ataxia, nystagmus, breathing abnormalities and developmental delay. Its neuroimaging hallmarks include molar tooth sign and batwing shaped fourth ventricle. As JS is associated with multiorgan involvement, these patients should enter a diagnostic protocol to assess systemic abnormalities. Extreme caution should be taken while administering drugs in these patients as they are prone to respiratory depression

  16. Cerebral perfusion scintigraphy and the exploration of dementia syndromes: An illustration with five clinical cases

    International Nuclear Information System (INIS)

    The epidemiological evidence suggests that individuals with higher education level have a reduced risk of developing dementia. Because cognitive reserve and its compensation mechanisms may modulate the clinical expression in neuro-degenerative pathology, it is important to study subjects who present mild cognitive disturbance with functional imaging. The cerebral SPECT has been used to determine regional uptake of radiotracer into the brain of patients with cognitive impairment. These abnormalities of blood flow were correlated with cognitive impairment. The cerebral SPECT is also useful to investigate preclinical dementia and to predict the evolution of cognitive disturbance. This article, reports some technical and semeiological notions and illustrate with five clinical cases the scintigraphic aspect of some dementia syndrome. (authors)

    Odontoid osteomyelitis is a rare disease which is frequently misdiagnosed as torticollis, leading to a delay in diagnosis. We present 2 illustrative cases and a systematic literature review summarizing previously reported cases. Odontoid osteomyelitis should be considered in children presenting with decreased head movements and with elevated erythrocyte sedimentation rate, particularly without improvement while receiving antiinflammatory treatment. Plain radiographs can be misleading, and magnetic resonance imaging should be performed for better visualization. PMID:27164466

  1. Illustrating the Interaction of Nature and People in Ecosystem Services: The Case of Terroir in Wine

    Science.gov (United States)

    Nicholas, K. A.

    2014-12-01

    The ecosystem services (ES) approach is increasingly used in research and policy, with the Common International Framework on Ecosystem Services (CICES) "cascade" gaining traction as a framework for conceptualizing the production of ecosystem services by the natural environment, and then people consuming these services and obtaining benefits depending on their values. However, uptake of the ES concept on the ground by ecosystem managers, and understanding by everyday citizens, is still limited. One barrier is the challenge of providing tangible, examples of everyday benefits and values that people can readily connect with the biophysical structures and functions that underlie their provision. Winegrowing offers one promising case to illustrate the linkages all along the chain of production and consumption of ecosystem services. The sensitive winegrape has long been known for its properties of terroir, where the taste of wine reflects the environmental conditions of the place where it is grown, a feature valued by consumers. Here the CICES framework is illustrated with the case of winegrowing, demonstrating that the current linear model of natural production and human consumption of ES needs to be modified for this case because people influence each of the five stages by shaping and responding to their environment, producing a two-way interaction between people and the environment throughout. For example, while natural drivers such as climate and soils are key to the provision of the service of winegrape yields, landowners modify the biophysical environment through site selection and growers modify plant ecophysiological function through farming practices such as pruning and irrigation in order to influence the final service. Similarly, winemakers' expertise is needed to transform the service of winegrape yields into the product of wine that can be enjoyed and valued by consumers, whose preferences shape wine styles as well. This case illustrates how incorporating

    2011-01-01

    Subcutaneous panniculitis-like T-cell lymphoma (SPTCL) is a very rare form of skin lymphoma that is localized primarily to the subcutaneous adipose tissue without palpable involvement of the lymph nodes. Diagnosis of SPTCL is a challenge, especially during its early phases when symptoms mimic other, more common conditions, such as benign panniculitis, eczema, dermatitis, psoriasis and cellulitis. Clinical and systemic features are nonspecific and can include fever, chills, and weight loss. Further complicating diagnosis is the high number of false negatives provided by biopsy. Here we present a case of SPTCL that illustrates the full course of the disease, from presentation and multiple misdiagnoses to correct disease recognition and successful treatment. A review of the challenges of diagnosis is provided with recommendations for more accurate and timely recognition of SPTCL. PMID:21461360

  4. Revisiting Cotard’s Syndrome: Illustration of Two Psychiatric Clinical Cases

    2016-07-01

    Full Text Available Background: Cotard’s Syndrome (CS is a rare and severe neuropsychiatric condition in which the central feature is the existence of nihilistic delusions. Controversy has ensued about the precise clinical picture Jules Cotard meant to describe and attempts have been made, more recently, not only to clarify the terminology, but also to define different types of this syndrome and explore its biological basis. Aims: We intend to briefly review the terminology, etiology, epidemiology and differential diagnosis of this syndrome, based on two clinical cases. Methods: Bibliographic search conducted through the electronic databases Medline and Gallica (French National Library, consultation of clinical records and direct interviews with the patients. Results and Conclusions: Typically the patients diagnosed with CS manifest the delusional idea that they are dying or already dead. However, it is also possible that they deny the existence of only some parts of their own body, or the functioning of some organs, and they may even sometimes deny the existence of the external world. We illustrate the case of a 66-year-old woman, diagnosed with bipolar affective disorder, admitted in the context of a severe depressive episode with psychotic symptoms, compatible with CS type II and the case of a young male aged 22, admitted due to a first  psychotic episode with schizophrenia like characteristics, presenting with nihilistic delusions compatible with CS type I.

    This series of three case studies illustrates the validity and usefulness of MIDAS, a microcomputer-based tool for integrated resource planning under uncertainty. The first, at Union Electric, serves to test and validate the model and to illustrate its use for demand/supply option evaluation. Focusing on nuclear plant life extension, the Virginia Power case demonstrates the model's extensive detail, particularly in the production cost and financial areas, as well as its flexibility in addressing approximately 70 uncertainty scenarios. Puget Sound Power Light, the third case, used MIDAS for the preparation of its integrated resource plan. A 108-endpoint decision tree illustrates the full power of the decision analysis capability.

  7. Process Philosophy and the Text-Image Interface: A Study of Three Western Australian Botanical Illustrators

    Full Text Available Botanical illustration combines scientific knowledge and artistic technique. However, whereas illustrated botanical images record static visual qualities, such as form and color, written botanical narratives supply crucial sensory, ecological, historical, and cultural contexts that complement visual representation. Understanding the text-image interface—where images and words intersect—contributes to humanities-based analyses of botanical illustration and illustrators. More specifically, a process philosophy perspective reveals the extent to which botanical representations engage the temporality, cyclicality, and contextuality of the living plants being illustrated. This article takes up these themes through a comparative theoretical study of three female Western Australian botanical illustrators, Georgiana Leake (1812–1869, Emily Pelloe (1877–1941, and Philippa Nikulinsky (born 1942, whose lives together span the 183 year history of the Swan River Colony and the state of Western Australia. I apply a processist framework to examine the text-image interface of their works. All three illustrators use some form of textuality: marginalia, annotations, written accompaniments, introductory statements, and other narrative materials. In examining their written commentaries and traces, I identify the emergence of a process mode of botanical illustration that represents plants as ecological, historical, cultural, and temporal organisms.

    Sirenomelia, a developmental defect involving the caudal region of the body, is associated with several internal visceral anomalies. We report a detailed spectrum of anomalies in an autopsy study of four fetuses with sirenomelia (gestational ages - 20, 21, 22.4, and 22.5 weeks). Three of the fetuses had single umbilical artery, with genitourinary and gastrointestinal anomalies. Central nervous system anomalies were evident in two of the fetuses, with alobar holoprosencephaly in one and lumbar meningomyelocele in another. The most common gastrointestinal anomaly was blind ended gut (imperforate anus), while esophageal atresia and omphalocele were noted in one case each. Renal hypoplasia was seen in two fetuses, renal agenesis in one and cystic renal dysplasia was noted in one case. Literature regarding pathogenesis of this condition is briefly discussed.

    2013-01-01

    Full Text Available Introduction: Pleomorphic adenoma (PA is the most common benign neoplasm of the major salivary glands arising primarily from the parotid gland. Computed tomography (CT is one of the primary imaging modalities used to assess the tumors of salivary glands. However, magnetic resonance imaging (MRI may provide additional information over CT. Case Report: We report the case of a 60-year-old male with a slowly enlarging, well-defined, round, painless, non-fixated, rubber-like swelling over the left ramus region below the ear, measuring about 4 × 4.5 cm, covering the lower border of the mandible near the angle. A provisional diagnosis of PA was given and CT and MRI were used to study the lesion. Discussion: Through this case, which was suspected to have undergone malignant transformation because of indistinct margins and focal hypodense areas on CT but was later confirmed to be a benign salivary gland tumor on MRI, we illustrate the role of CT and MRI as diagnostic aids in PA and emphasize on what should be the choice of imaging modality for parotid tumors.

    Lumbar disc herniation (LDH) is a common disease that induces back pain and radicular pain. The most efficient method for the treatment of lumbar disc herniation is still controversial. Spontaneous regression of LDH has been recognized with the advancement of radiological diagnostic tools and can explain the reason of spontaneous relief of symptoms without treatment. The proposed hypotheses are; dehydration, retraction of the disc to the hernia in the annulus fibrosis, enzymatic catabolism and phagocytosis. In this study, the case of a patient with huge lumbar disc hernia regressing by itself has been presented and the potential mechanisms of disc regression have been discussed. PMID:26907997

    Directory of Open Access Journals (Sweden)

    André Andrade Longaray

    2016-03-01

    Full Text Available Since its introduction in the early 1990s, trade marketing has played a significant role in companies and their distribution channels, focusing on the consolidation of marketing strategy at the point of purchase. In practice, one of the main obstacles for a more widespread use of trade marketing has been the lack of management tools allowing visualisation of the consequences of trade marketing in the organisation's objectives. This study shows the use of the Multi-Criteria Decision Aiding–Constructivist methodology model as an instrument of intervention in a case study conducted in a pharmaceutical company. A customised evaluation model was built interactively by interviewing decision makers to identify, organise, measure, and integrate those factors considered necessary and sufficient for the management of trade marketing. The constructed model enables executives to incorporate unique aspects of the company and the environment, expanding the possibilities for performance evaluation of trade marketing in the organisation.

    Pain evoked by tangential movement across the skin is usually defined as dynamic mechanical allodynia (DMA). Some patients complain of DMA as troublesome as spontaneous pain and refer a marked interfering with activities of daily living and sleep. Pathophysiology of DMA is complex and can be related to several mechanisms, both nociceptive and neuropathic. Five exemplificative clinical cases of DMA are presented, each associated to a possible specific mechanism: injured skin DMA, peri-injured skin DMA, far injury DMA, nerve-confined DMA and fear DMA (pseudo allodynia). The identification of these subcategories of DMA can stimulate further studies aimed at evaluating the usefulness of a mechanism-based therapy for the different clinical forms of DMA. PMID:26879154

    Full Text Available Objective. The effectiveness of an individualized and everyday approach to cognitive rehabilitation for schizophrenia was examined in a case study. Method. After cognitive and functional assessment, concrete objectives were targeted for the person’s everyday complaints. Strategies were constructed based on an analysis of the cognitive profile, daily life functioning, and processes involved in activities. They included a memory strategy for reading, a diary to compensate memory difficulties, and working memory exercises to improve immediate processing of information when reading and following conversations. Efficacy was assessed with outcome measures. Results. The program had beneficial effects on the person’s cognitive and everyday functioning, which persisted at a 3-year follow-up. Conclusion. Findings provide suggestive evidence that an individualized and everyday approach may be a useful alternative in order to obtain a meaningfully lasting transfer of training to daily life, compared to the nomothetic ones which dominate the field.

    2012-01-01

    Full Text Available Obsessive compulsive disorder (OCD is one of the most frequently occurring psychiatric conditions in older adults. While exposure and response prevention (ERP is considered the most effective psychological treatment for children and adults with OCD, research investigating its effectiveness for older adults is scarce. This clinical case study investigates the effectiveness of ERP in an 80-year-old man with a 65-year history of OCD. The client received 14 individual, 50-minute ERP treatment sessions. Clinician-based Y-BOCS scores reduced by 65% from 20 (moderate at pretreatment to 7 (subclinical at 7-month posttreatment followup. OCI-R total scores reduced by 45% from 38 at baseline to 21 at 7-month follow-up. Despite his long history of the disorder, ERP was effective and well tolerated. The application of ERP for older adults with OCD, including age-specific modifications that may be required for this treatment approach, is discussed.

    Ventricular constraint therapy has been used to prevent and reverse the progression of heart failure in ischemic and nonischemic cardiomyopathies. We hypothesized that ventricular restraint should be tried by closing the pericardium that was previously opened following left ventricle topographical projection. The surgical technique presentation is illustrated by a remarkable 13-year outcome of one patient with dilated cardiomyopathy treated surgically by mitral prosthesis, Cox/Maze III surgery to treat atrial fibrillation, and associated to the ventricular constraint using the patient's own pericardium. The ventricular pericardial restraint role is unclear, since the patient had multiple corrections that could be responsible for the good outcome; however it is viable deserving investigations.

    Background. Injuries to the elbow have led to consequences varying from significant limitation in function to loss of the entire upper limb. Soft tissue reconstruction with durable and pliable coverage balanced with the ability to mobilize the joint early to optimize rehabilitation outcomes is paramount. Methods. Methods of flap reconstruction have evolved from local and pedicled flaps to perforator-based flaps and free tissue transfer. Here we performed a review of 20 patients who have undergone flap reconstruction of the elbow at our institution. Discussion. 20 consecutive patients were identified and included in this study. Flap types include local (n = 5), regional pedicled (n = 7), and free (n = 8) flaps. The average size of defect was 138 cm2 (range 36–420 cm2). There were no flap failures in our series, and, at follow-up, the average range of movement of elbow flexion was 100°. Results. While the pedicled latissimus dorsi flap is the workhorse for elbow soft tissue coverage, advancements in microvascular knowledge and surgery have brought about great benefit, with the use of perforator flaps and free tissue transfer for wound coverage. Conclusion. We present here our case series on elbow reconstruction and an abbreviated algorithm on flap choice, highlighting our decision making process in the selection of safe flap choice for soft tissue elbow reconstruction.

    Full Text Available We report a common diabetes management problem illustrated by an adolescent female university student with recurrent episodes of hypoglycaemia on Tuesdays when she has intensive academic activity lasting most of the day. Steps taken to reduce the risk of hypoglycaemia were patient education and empowerment, frequent self monitoring of blood glucose, reduction in insulin dose on Tuesdays and emphasizing availability of ongoing professional guidance and support anytime she may need it. One of the challenges encountered in the management of this patient was her family’s inability to afford the cost of basal-bolus regimen or continuous subcutaneous insulin infusion via insulin pump; the two insulin regimens that best fit into university lifestyle. Conclusion: Adolescents with diabetes mellitus attending tertiary educational institutions may be at increased risk of hypoglycaemia, particularly on days when they have intensive academic activities.

    The child who presents with fever, limp and hip pain will often undergo multiple diagnostic procedures before a definitive diagnosis is made. We describe a diagnostically challenging case of a 14-year-old boy presenting with an atraumatic painful limp and pyrexia. Eventually the diagnosis of obturator internus muscle abscess with associated ischial osteomyelitis was made. Of the 19 previous cases reported, four children had associated osteomyelitis and were of an older age. Symptomatology varies, clinical examination is non-specific and the diagnosis can be difficult. Haematological indices are more predictive than in cases of classical osteomyelitis or septic arthritis. Subtle features on conventional radiography and isotope bone scanning should not be overlooked while CT and MRI may be complementary in diagnosis.

  10. An illustrative note on the system price effect of wind and solar power. The German case

    International Nuclear Information System (INIS)

    Exposing wind and solar power to the market price signal allows for cost-efficient investment decisions, as it incentivizes investors to account for the marginal value (MVel) of renewable energy technologies. As shown by Lamont (2008), the MVel of wind and solar power units depends on their penetration level. More specifically, the MV el of wind and solar power units is a function of the respective unit's capacity factor and the covariance between its generation profile and the system marginal costs. The latter component of the MVel (i.e., the covariance) is found to decline as the wind and solar power penetration increases, displacing dispatchable power plants with higher short-run marginal costs of power production and thus reducing the system marginal costs in all generation hours. This so called 'system price effect' is analyzed in more detail in this paper. The analysis complements the work Lamont (2008) in two regards. First of all, an alternative expression for the MVel of wind and solar power units is derived, which shows that the MVel of fluctuating renewable energy technologies depends not only on their own penetration level but also on a variety of other parameters that are specific to the electricity system. Second, based on historical wholesale prices and wind and solar power generation data for Germany, a numerical 'ceteris paribus' example for Germany is presented which illustrates that the system price effect is already highly relevant for both wind and solar power generation in Germany.

    We describe two patients with severe developmental delay, hypotonia and breathing abnormalities initially diagnosed with the autosomal recessive Joubert syndrome (JBS) who at a later stage appeared to carry chromosomal abnormalities. One case was due to a 4.8 Mb terminal 1q44 deletion, and the other due to a 15.5 Mb duplication of Xq27.2-qter containing the MECP2 gene. Critical evaluation of the clinical data showed that, retrospectively, the cases did not fulfil the diagnostic criteria for JBS, and that the diagnosis of JBS was incorrectly made. We discuss the diagnostic pitfalls and recommend adhering strictly to the JBS diagnostic criteria in the case of a negative molecular diagnosis. Critical assessment of the MRI findings by a specialized neuroradiologist is imperative. As chromosomal abnormalities may give rise to symptoms resembling JBS, we recommend array-based screening for segmental aneuploidies as an initial genetic test in all cases with a JBS-like phenotype.

    Exposing wind and solar power to the market price signal allows for cost-efficient investment decisions, as it incentivizes investors to account for the marginal value (MV{sup el}) of renewable energy technologies. As shown by Lamont (2008), the MV{sup el} of wind and solar power units depends on their penetration level. More specifically, the MV el of wind and solar power units is a function of the respective unit's capacity factor and the covariance between its generation profile and the system marginal costs. The latter component of the MV{sup el} (i.e., the covariance) is found to decline as the wind and solar power penetration increases, displacing dispatchable power plants with higher short-run marginal costs of power production and thus reducing the system marginal costs in all generation hours.

    Many scientific inventions (SI) throughout history were inspired by heuristic prototypes (HPs). For instance, an event or piece of knowledge similar to displaced water from a tub inspired Archimedes' principle. However, the neural mechanisms underlying this insightful problem solving are not very clear. Thus, the present study explored the neural correlates used to solve SI problems facilitated by HPs. Each HP had two versions: a literal description with an illustration (LDI) and a literal description with no illustration (LDNI). Thirty-two participants were divided randomly into these two groups. Blood oxygenation level-dependent fMRI contrasts between LDI and LDNI groups were measured. Greater activity in the right middle occipital gyrus (RMOG, BA19), right precentral gyrus (RPCG, BA4), and left middle frontal gyrus (LMFG, BA46) were found within the LDI group as compared to the LDNI group. We discuss these results in terms cognitive functions within these regions related to problem solving and memory retrieval. PMID:25840359

    Full Text Available A 16-year-old boy whose diabetes mellitus was diagnosed 3 months previously in a private hospital but was not placed on medication. The presenting complaints were fast breathing for 24 hours, weakness for 2 hours, and unresponsiveness to calls for 0.5 hours. His father was obese with type 2 diabetes mellitus and died 8 months earlier from cardiac arrest. His birthweight was low, 2.2kg. At first presentation, his weight, BMI and blood pressure were 60kg (25th-50th percentile, 19.4kg/m2 (25thpercentile and 110/70mmHg (systolic BP 50th percentile, diastolic BP 50th-90th percentile, respectively. He was managed for diabetic ketoacidosis and was discharged on subcutaneous premixed insulin, 1 Unit/kg/day. At point of discharge, weight and BP were 60.5 kg and 120/70 mmHg, respectively. The patient defaulted but presented again 6 months later at the age of 17 years. At second presentation, his weight, BMI and BP were 89 kg (95th percentile, 27.5 kg/m2 (90th-95th percentile and 180/80 mmHg (systolic 99th percentile; diastolic 90th percentile, respectively. His waist circumference was 98.7cm (> 90th percentile. We had no record of previous waist circumference. His lipid profile showed low HDL-cholesterol 0.7252 mmol/L [(28mg/dl; <5thpercentile]. His fasting blood glucose and HbA1C were 6.5 mmol/L (117mg/dl and 34 mol/mol (5.3%, respectively. A diagnosis of metabolic syndrome in a patient with ketosis-prone type 2 diabetes was made. He was referred to the pediatric cardiologist for management of his hypertension. He defaulted again and was lost to follow up. Conclusion: This report illustrates the association of low birth weight and rapid weight gain with metabolic syndrome in adolescence.

  19. Which Fungus Originally was Trichophyton mentagrophytes? Historical Review and Illustration by a Clinical Case.

    Several dermatophytes producing numerous pyriform or round microconidia were called Trichophyton mentagrophytes. Among these dermatophytes are the teleomorph species Arthroderma benhamiae, Arthroderma vanbreuseghemii and Arthroderma simii, and other species such as Trichophyton interdigitale, Trichophyton erinacei and Trichophyton quinckeanum for which only the anamorph is known. Confusion exists about which fungus should be really called T. mentagrophytes and about the rational use of this name in practice. We report a case of beard ringworm (tinea barbae) with A. vanbreuseghemii. According to both clinical signs and the type of hair parasitism, this case was exactly compatible to the first description of a non-favic dermatophytosis by Gruby under the name of "mentagrophyte" from which was derived the dermatophyte epithet mentagrophytes. In addition, the phenotypic characters of the isolated fungus in cultures perfectly matched with those of the first description of a dermatophyte under T. mentagrophytes by Blanchard (Parasites animaux et parasites végétaux à l'exclusion des Bactéries, Masson, Paris, 1896). In conclusion, T. mentagrophytes corresponds to the fungus later named A. vanbreuseghemii. However, because the neotype of T. mentagrophytes was not adequately designated in regard to the ancient literature, we would privilege the use of A. vanbreuseghemii and abandon the name of T. mentagrophytes.

A spinal shortening osteotomy procedure has previously been described for the correction of the sagittal balance in a late kyphotic deformity, but there have been no reports on this as a surgical treatment in the acute stage. Thus, the aim of this report is to present the surgical techniques and clinical results of 3 patients who were treated with this procedure. Three patients with tuberculous spondylitis at the thoracic spine were surgically treated with this procedure. All the patients presented with severe progressive back pain, kyphotic deformity and neurological deficit. The patients recovered uneventfully from surgery without further neurological deterioration. Their pain was improved and the patients remained free of pain during the follow-up period. In conclusion, posterior spinal shortening osteotomy is an alternative method for the management of tuberculous spondylitis. PMID:22164318

    Full Text Available Tetanus is a life threatening infectious disease caused by the anaerobic Gram-positive bacillus Clostridium tetani which enters the body through an open wound. A 60-years-old male patient who was referred to our institute with a history of a rusted iron with complaints of nail prick injury and difficulty in opening the mouth. This individual previously not receive tetanus immunoglobulin. Prior to coming to our institute, the rusted iron nail was extracted and he had received tetanus toxoid. After he was admitted in the tetanus ward at our institute, he developed spasms. He was treated with intravenous diazepam and tetanus immunoglobulins. Wound exploration revealed a retained residual foreign body that was a part of his rubber foot wear in the wound. He died on the sixth day of admission. The present case highlights the need for administering appropriate active and passive immunization for tetanus along with meticulous wound care.

    The epidemiological evidence suggests that individuals with higher education level have a reduced risk of developing dementia. Because cognitive reserve and its compensation mechanisms may modulate the clinical expression in neuro-degenerative pathology, it is important to study subjects who present mild cognitive disturbance with functional imaging. The cerebral SPECT has been used to determine regional uptake of radiotracer into the brain of patients with cognitive impairment. These abnormalities of blood flow were correlated with cognitive impairment. The cerebral SPECT is also useful to investigate preclinical dementia and to predict the evolution of cognitive disturbance. This article, reports some technical and semeiological notions and illustrate with five clinical cases the scintigraphic aspect of some dementia syndrome. (authors)

    The aim of this study is to develop a method that would enable the company to prioritize the means contributing the most to its performance. The proposed method is based on the profit margin (an economical performance measure of the company), the customer's risk, the costs of maintenance and the employee's safety. The prioritization method of resources was applied to the data obtained from a small subcontracting business in mechanics. The theoretical foundations of this method are based on a multi-criteria approach using the attribution of criticality indexes for nine criteria linked to the financial loss.

  9. Study of job burnout in technical writers and technical illustrators/designers at LLNL

    Rice, J A

    1998-06-03

    According to the American Institute of Stress, job stress is estimated to cost American industry more than $200 billion a year. These costs are, in part, related to the estimated 1 million employees that will be absent on an average workday because of stress; 75 percent of visits to primary care physicians are for stress-related problems. California workers' compensation claims for stress cost $1 billion for medical and legal fees alone (Murphy, 1997). But, there is another dimension to stress that needs to be addressed. Job stress can be a precursor to job burnout. Burnout is a loss of motivation, and antidotes for job stress will not necessarily alleviate or stop job burnout. Job burnout is experienced as exhaustion on physical, emotional, and cognitive levels. Burnout can include withdrawal and decreasing involvement on the job, seriously affecting job satisfaction, turnover, absenteeism, and productivity (Dwyer & Ganster, 1991; Erickson & Gunderson, 1972; Spector & Jex, 1991). The research project described in this paper examined whether job burnout exists in the technical writer and technical illustrator/designer occupations in the Technical Information Department at Lawrence Livermore National Laboratory. This study also determined at what age and after how many years of service these employees were most likely to experience job burnout, whether it affects men or women most, and if writers in a technical organization experience job burnout more than illustrators/designers in that organization.

    Ezzahri, Younès; Joulain, Karl

    2014-09-01

    The natural transition from the radiative regime to the conductive regime of heat transfer between two identical isotropic nonmagnetic dielectric solid materials is questioned by investigating the possibility of induced phonon transfer in vacuum. We describe the process in a general way assuming a certain phonon coupling mechanism between the two identical solids, then we particularly illustrate the case of coupling through the Casimir force. We analyze how this mechanism of heat transfer compares and competes with the near field thermal radiation using a local model of the dielectric function. We show that the former mechanism can be very effective and even surpass the latter mechanism depending on the nature of the solid dielectric materials, the distance gap between them, as well as the operating temperature regime.

    Most of tight-binding studies of transition metal based systems deviating from perfect bulk (surfaces, nanoparticles, alloys) are based on local charge neutrality rules per site, per valence orbital and per element. Unfortunately, such rules do not hold per spin when interested in magnetic elements. We present here a simple way to characterize the variation of the magnetic moment with the environment and to generalize the tight-binding expression of the energy to account for magnetism. This is illustrated in the particular case of cobalt, going from perfect pure bulk to surface, nanoparticles and then CoPt alloy.

  16. Mega alloprosthesis in limb-sparing surgery: a case illustration, Hospital Univ. Science of Malaysia (HUSM) experience

    International Nuclear Information System (INIS)

    A case illustration of our early experience of limb-sparing surgery in muskuloskeletal tumors using a mega alloprosthesis was discussed. The presentation was of a 42 year olds Malay woman with a solitary pathological fracture in a metastatic lesion to the upper third of right femur. This was found to be histologically identical to the stromal component of malignant metastatic Cytosarcoma Phylloides of the breast. It represented the first reported histologically confirmed skeletal manifestation of rare breast pathology in HUSM. Cytosarcoma Phylloides of the breast appeared to encompass a diverse group of tumors with variable unpredictable behaviors. Although it accounted for 0.3-1.0% of all breast neoplasms, it could behave in a malignant fashion and metastasized hematogenously to the skeletal system. The solitary nature of the metastatic lesion and the pathological fracture which the patient sustained, warranted us to perform a surgical stabilization not only to alleviate the pain, to eradicate the tumor bulk, but also to restore loading capacity and preserving function and mobility. It had been achieved by wide excision of the metastatic lesion and the integration of a massive allograft, polymethylmethacrylate and an implant into a well-structured composite unit. Augmentation to revascularise the avascular allograft bone had also been done with an ipsilateral segmental free vascularised fibular composite graft, which also acted as a live bone strut for mechanical maintenance once resorption of the allograft commenced, and the fibular graft hypertrophied. Adjuvant chemotherapy had been administered to combat systemic micrometastasis. As the tumor margins were histologically confirmed to be free and the patient had passed the early graft rejection period, close monitoring was mandatory for an effective tumor control and avoidance of complications. This new technique of a massive allograft combined with an endoprosthesis and a segmental live fibular graft promises to

  19. Use of geo-scientific arguments in the Nirex phased geological repository concept: illustrative desk study

    International Nuclear Information System (INIS)

    A desk study recently undertaken by Nirex used data, collected from now-ceased investigations of the Sellafield site (west Cumbria, UK) undertaken in the 1990's, to consider the implications of locating the Nirex Phased Geological Repository Concept (PGRC) in deep rock formations present at the west Cumbrian coast that contain brines in a slow-moving groundwater flow system. Work undertaken brought together geochemical data and interpretation [1], addressing some questions that were posed during active Sellafield investigations concerning the distribution, composition, origin and age of the brine. The desk study also considered geochemical evidence that has a bearing on understanding the hydrodynamic stability of the brine, noting that it has been investigated in a zone where there are quite sharp changes in physical and chemical groundwater conditions over rather short distances; the simplified hypothesis that this brine is 'very old and virtually immobile' is considered. Other important parts of the scientific framework that provide complementary knowledge and insights were utilised for this desk study; physical hydrogeology and numerical modelling, basinal geology, structure and rock properties, and mineralogy were integrated with geochemistry to develop an understanding of the behaviour of the groundwater system in the study region in terms of its evolution to present day, and its potential future behaviour. Semi-quantitative and qualitative comparison between hydrodynamic and geochemical estimates of water ages are reported. The main assumptions and simplifications in each case that affect the degree of comparability are described in that report, and the consistencies and inconsistencies are discussed and reconciled as far as possible. Geochemical ages for time since recharge of the water in the brine are upwards of 1.6 million years. A probable maximum age of 10 million years is inferred from an assumption about how groundwater history might be coupled to

  20. Adsorption of radionuclides on minerals studies illustrating the effect of solid phase selectivity and of mechanisms controlling sorption processes

    International Nuclear Information System (INIS)

    Currently, extensive research is being done on the geochemistry of Yucca Mountain, Nevada. The purpose of this research is to determine whether this location would be suitable as a permanent high-level radioactive waste repository. Site characterization tests must prove that Yucca Mountains' geology will safely isolate radioactive waste from the environment for at least 10,000 years before approval is granted. In order for this to occur, it is necessary to study the sorptive properties of the host rock, and its selectivity in sorption of solutions containing multiple radionuclides. Validation of this must occur, because in the case of a catastrophic leak, the host rock must have properties that will retard the migration of radionuclides. Columnar experimental techniques were employed using goethite, (a hydrous iron oxide), beidellite (clay mineral), ampersand open-quotes nonscentsclose quotes (a zeolitized volcanic tuff) as sorbents. These sorbents were used to measure the isotherms of an identical binary solution (Ni-Sr) to illustrate the selectivity that occurs in different minerals. In beidellite, the sorption process was ideal, while for open-quotes nonscentsclose quotes there was a strong preference for Sr2+. The sorption process was modeled (Ni-Sr open-quotes Nonscentsclose quotes) using ion exchange theory as the mechanism. In goethite, the sorption of Ni-Sr showed a complete preference for Ni2+ at a pH of 7. In various other systems for goethite. Co-Ni (pH=7) was ideal (no selectivity) where the ratios in the solid and solution phases were relatively equal. Conversely in the case of the Pb-Ni system, the Pb2+ ion predominated completely in the solidphase over Ni2+ at a pH of 5.5. Noting the strong effect of pH on the sorption process in goethite, the selectivity could not necessarily be credited to ion-exchange because of possible exclusion from charged sites at low pH values

    This case study examined the effects of auditory working memory (WM) training on neuroplastic changes in stroke survivors and how such effects might be influenced by self-perceived stress. Two participants with a history of stroke participated in the study. One of them had a higher level of self-perceived stress. Both participants underwent a course of auditory WM training and completed baseline and post-training assessments such as self-perceived stress, performance satisfaction questionnaires, behavioral task performance, and functional magnetic resonance imaging. They were trained on a computerized auditory WM task (n-back) 5 days a week for 6 weeks, for a total of 20 h. Participant 1 had high levels of perceived stress, both pre- and post-training, and showed improvement on the satisfaction aspect of functional engagement only. Participant 2 had lower levels of perceived stress and demonstrated improvements on all performance tasks. Neuroimaging results showed evidence of improved neural efficiency on the trained task for participant 2. The results shed light on the need to evaluate psychological influences, e.g., stress, when studying the neuroplastic changes in people with stroke. However, the case design approach and other factors that might have positively influenced outcomes mean that these results must be interpreted with a great deal of caution. Future studies using a larger sample are recommended to verify the findings. PMID:27625614

  5. Some implications of time series analysis for describing climatologic conditions and for forecasting. An illustrative case: Veracruz, Mexico

    The common practice of using 30-year sub-samples of climatological data for describing past, present and future conditions has been widely applied, in many cases without considering the properties of the time series analyzed. This paper shows that this practice can lead to an inefficient use of the information contained in the data and to an inaccurate characterization of present, and especially future, climatological conditions because parameters are time and sub-sample size dependent. Furthermore, this approach can lead to the detection of spurious changes in distribution parameters. The time series analysis of observed monthly temperature in Veracruz, Mexico, is used to illustrate the fact that these techniques permit to make a better description of the mean and variability of the series, which in turn allows (depending on the class of process) to restrain uncertainty of forecasts, and therefore provides a better estimation of present and future risk of observing values outside a given coping range. Results presented in this paper show that, although a significant trend is found in the temperatures, giving possible evidence of observed climate change in the region, there is no evidence to support changes in the variability of the series and therefore there is neither observed evidence to support that monthly temperature variability will increase (or decrease) in the future. That is, if climate change is already occurring, it has manifested itself as a change-in-the-mean of these processes and has not affected other moments of their distributions (homogeneous non-stationary processes). The Magicc-Scengen, a software useful for constructing climate change scenarios, uses 20-year sub-samples to estimate future climate variability. For comparison purposes, possible future probability density functions are constructed following two different approaches: one, using solely the Magicc-Scengen output, and another one using a combination of this information and the time

  8. Some illustrative examples from parametric studies for a reference HLW repository using ACGEO

    International Nuclear Information System (INIS)

    Spent fuels are to be directly disposed of and the only type of HLW in Korea. According to the basic repository design, which is similar to Swedish KBS-3 repository concept, spent fuel is encapsulated in corrosion resistant canisters, and then emplaced into the deposition holes surrounded by high density bentonite clay in tunnels at a depth of ∼500 m in a plutonic rock (Fig. 1). The objective of this paper is to show how we could show reliability of radiological safety assessment through probabilistic calculation with parameters having uncertainties associated with safety of HLW system. To demonstrate a typical way, possibly among many others, some probabilistic calculation results for nuclide release and transport in the near- and farfield of the repository when such selected key parameters as buffer thickness, nuclide travel length in the fractured rock medium, and initial number of defective canisters are varying are presented. ACGEO, a case file developed by utilizing AMBER, a compartment modeling software package was used for calculation

  11. Implications of a consumer-based perspective for the estimation of GHG emissions. The illustrative case of Luxembourg

    International Nuclear Information System (INIS)

    The Kyoto protocol has established an accounting system for national greenhouse gas (GHG) emissions according to a geographic criterion (producer perspective), such as that proposed by the IPCC guidelines for national GHG inventories. However, the representativeness of this approach is still being debated, because the role of final consumers (consumer perspective) is not considered in the emission allocation system. This paper explores the usefulness of a hybrid analysis, including input–output (IO) and process inventory data, as a complementary tool for estimating and allocating national GHG emissions according to both consumer- and producer-based perspectives. We assess the historical GHG impact profile (from 1995 to 2009) of Luxembourg, which is taken as a case study. The country's net consumption over time is estimated to generate about 28,700 Gg CO2e/year on average. Compared to the conventional IPCC inventory, the IO-based framework typically shows much higher emission estimations. This relevant discrepancy is mainly due to the different points of view obtained from the hybrid model, in particular with regard to the contribution of imported goods and services. Detailing the GHG inventory by economic activity and considering a wider system boundary make the hybrid IO method advantageous as compared to the IPCC approach, but its effective implementation is still limited by the relatively complex modeling system, as well as the lack of coordination and scarce availability of datasets at the national level. - Highlights: • GHG emissions for Luxembourg are assessed using hybrid input–output (IO) modeling. • Consumer and producer perspectives are compared for the period 1995–2009. • IO-based GHG profiles are remarkably higher than traditional IPCC inventorying. • IO-based GHG accounting presents some advantages but is limited in implementation. • Key-aspects of IPCC and IO-based methods are extensively investigated and compared

    The joint study of pressure (P-) and shear (S-) wave velocities (VP and VS, respectively), as well as their ratio (VP/VS), has been used for many years at large scales (compared to near-surface applications) to study fluids in earth materials. Theoretical and experimental developments have been aimed at understanding the effect of saturation and pore fluids on body wave velocities, more particularly in consolidated media. In the field of hydrocarbon exploration for instance, the measurement of VP/VS ratio helps discriminating different pore fluids in reservoirs. But it is only until recently that this approach has been successfully applied to the characterization of hydrosystems. We showed, thanks to controlled field experiments, the ability of VP/VS ratio in imaging spatial and/or temporal variations of water content at the critical zone scale. These promising results still lack quantitative links between water saturation and seismic properties in such materials and context. We consequently developed laboratory experiments to simulate seismic acquisitions on small-scale controlled granular media with varying water levels. The first results clearly showed the influence of the water level on first arrival times, dispersion and amplitude of the recorded wavefields, and how these measurements could be used as monitoring tools.

    New targeted treatments are being used for patients affected by certain types of cancers with specific gene dysregulation. These new treatments transform the prognosis for the patients but the exact way in which they work is often incompletely known. This can prove to be problematic with regard to potential side effects. Ophthalmologic side effects are particularly difficult to detect in animal models. MEK inhibitors are among these new targeted treatments for which the indications are broad. One of the reported side effects of MEK inhibitors is the appearance of atypical multifocal serous chorioretinopathies which, when present, occur rapidly after starting the treatment and disappear soon after stopping it. We report two documented cases of serous chorioretinopathies secondary to the use of selumetinib, an MEK inhibitor. Both patients were followed for several months after initiating the treatment, using angiography, OCT, and filtered photographs. Only a very few cases have been reported, and the detailed description of two clear-cut cases and their management, as well as a review of the current literature, seems a good way to approach the management of this complication.

  3. Neuroimaging in the Differential Diagnosis of Primary Progressive Aphasia – Illustrative Case Series in the Light of New Diagnostic Criteria

    International Nuclear Information System (INIS)

    Primary progressive aphasia (PPA) is a progressive language disorder associated with atrophy of the dominant language hemisphere, typically left. Current PPA criteria divide PPA into three variants: non-fluent (nfvPPA), semantic (svPPA) and logopenic (lvPPA). The classification of PPA into one of the three variants may be performed at 3 levels: I) clinical, II) imaging-supported, III) definite pathologic diagnosis. This paper aimed at assessing the feasibility of the imaging-supported diagnostics of PPA variants in the Polish clinical setting with access to magnetic resonance imaging (MRI) and single-photon emission computed tomography (SPECT) examinations. We present the clinical and neuroimaging data on 6 patients (4 women, 2 men) clinically diagnosed with PPA (3 with nfvPPA and 3 with lvPPA) in whom MRI and SPECT were performed in order to determine if imaging-supported diagnosis could be established in those cases. In 4 individuals (2 with nfvPPA and 2 with lvPPA) clinical diagnosis was supported by neuroimaging (SPECT, albeit not MRI), thus level II of PPA diagnosis could be established in those cases. MRI results were either inconsistent with the clinical diagnosis (Patients 1 and 2) or a mixed pattern of atrophy was observed (Patients 3–6). Imaging-supported diagnosis of PPA variant is more feasible with quantitative analysis of SPECT images than with purely qualitative visual analysis of MRI. Hypoperfusion abnormalities evidenced by SPECT are more variant-specific than patterns of atrophy

    The process of β-amyloid accumulation in cerebral vessels is presented. Cerebral amyloid angiopathy (CAA) was confirmed during an autopsy. It was diagnosed according to the Boston criteria. Cerebral amyloid angiopathy can involve all kinds of cerebral vessels (cortical and leptomeningeal arterioles, capillaries and veins). The development of CAA is a progressive process. β-amyloid appears first in the tunica media, surrounding smooth muscle cells, and in the adventitia. β-amyloid is progressively accumulated, causing a gradual loss of smooth muscle cells in the vessel wall and finally replacing them. Then, the detachment and delamination of the outer part of the tunica media results in the "double barrel" appearance, fibrinoid necrosis, and microaneurysm formation. Microbleeding with perivascular deposition of erythrocytes and blood breakdown products can also occur. β-amyloid can also be deposited in the surrounding of the affected vessels of the brain parenchyma, known as "dysphoric CAA". Ultrastructurally, when deposits of amyloid fibers were localized in or outside the arteriolar wall, the degenerating vascular smooth muscle cells were observed. In the Institute of Psychiatry and Neurology the study was carried out in a group of 48 patients who died due to intracerebral hemorrhage caused by sporadic CAA. PMID:24375040

  8. Energy transition: an illustration of the effects on electricity park dynamics in the case of a 'Renewable Energy' scenario

    International Nuclear Information System (INIS)

    At present, France's energy mix emits relatively little greenhouse gas, thanks to the energy policies that were adopted in the 1970's. These policies were based on an important choice: that of heavy reliance on hydro-nuclear power. Today, the pursuit of efforts to reduce carbon emissions is again a top priority. Being non-emitters and inexhaustible, Renewable Energies (RE) such as wind and solar power must be developed. Moreover, Japan's recent catastrophe has really left its mark, calling into question the future energy mix. Is it possible to have a low emissions' mix without resorting to nuclear power? What would be the cost? What would be the impact of closing down nuclear capacity and substituting RE in its stead?

    In order to comprehend the impact of music therapy or music therapy processes, a researcher might look for an approach where the topic under investigation can be understood within a broader context. This calls for a rich inclusion of data and consequently a limited number of participants and may be...... achieved through the use of objectivist case study research. The strength of the case study design is that it allows for uncovering or suggesting causal relationships in real-life settings through an intensive and rich collection of data. According to Hilliard (1993), the opposite applies for extensive...... designs, in which a small amount of data is gathered on a large number of subjects. With the richness of data, the intensive design is ―the primary pragmatic reason for engaging in single-case or small N research‖ (p. 374) and for working from an idiographic rather than a nomothetic perspective....

    Hypoglycemia is a common problem among neonates. Transient in nature, it usually resolves with an increase in glucose intake. However, as clinicians, we must recognize that prolonged hypoglycemia may be caused by increased insulin production. Nesidioblastosis is one cause of persistent hyperinsulinism of the newborn. This case study reviews fetal physiology, neonatal presentation, and treatment. PMID:9325879

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

  6. Vertebral Angiosarcoma. Case Study.

    Science.gov (United States)

    Guzik, Grzegorz

    2015-01-01

    Bone angiosarcomas, especially vertebral angiosarcomas, are very rare. There are no studies based on large clinical samples in the literature, and only a few single case reports can be found. The symptoms of the disease are not specific. It is usually detected incidentally or at a late stage when pathological vertebral fractures or neurological complications occur. Diagnostic imaging and history help to recognize the tumour behind the symptoms, but do not allow accurate clinical diagnosis. The basis for a diagnosis is the histopathological examination supported by immunohistochemistry (IHC) assays. The case of a 26-year-old woman with an angiosarcoma involving the eighth thoracic vertebra we report reflects diagnostic problems adversely affecting the efficacy and accuracy of treatment offered to patients. The patient underwent three surgeries of the spine, including two biopsies. A needle biopsy did not provide sufficient information for the diagnosis. An open excisional biopsy, which at the same time temporarily reduced neurological deficits in the patient, was the only chance to obtain an accurate diagnosis. The third surgery was posterior decompression of the spinal cord due to the rapidly escalating paraparesis. It was not until 8 weeks later that the final diagnosis was established. At that time, the patient could not be qualified for any supplementary treatment. The patient died in hospital 6 months after the onset of disease. PMID:26468177

  8. A Competence-Based Science Learning Framework Illustrated Through the Study of Natural Hazards and Disaster Risk Reduction

    Science.gov (United States)

    Oyao, Sheila G.; Holbrook, Jack; Rannikmäe, Miia; Pagunsan, Marmon M.

    2015-09-01

    This article proposes a competence-based learning framework for science teaching, applied to the study of 'big ideas', in this case to the study of natural hazards and disaster risk reduction (NH&DRR). The framework focuses on new visions of competence, placing emphasis on nurturing connectedness and behavioral actions toward resilience and sustainability. The framework draws together competences familiarly expressed as cognitive knowledge and skills, plus dispositions and adds connectedness and action-related behaviors, and applies this by means of a progression shift associated with NH&DRR from abilities to capabilities. The target is enhanced scientific literacy approached through an education through science focus, amplified through the study of a big idea, promotion of sustained resilience in the face of disaster and the taking of responsibilities for behavioral actions. The framework is applied to a learning progression for each interrelated education dimension, thus serving as a guide for both the development of abilities and as a platform for stimulating student capabilities within instruction and assessment.

  9. Goiania incident case study

    International Nuclear Information System (INIS)

    The reasons for wanting to document this case study and present the findings are simple. According to USDOE technical risk assessments (and our own initial work on the Hanford socioeconomic study), the likelihood of a major accident involving exposure to radioactive materials in the process of site characterization, construction, operation, and closure of a high-level waste repository is extremely remote. Most would agree, however, that there is a relatively high probability that a minor accident involving radiological contamination will occur sometime during the lifetime of the repository -- for example, during transport, at an MRS site or at the permanent site itself during repacking and deposition. Thus, one of the major concerns of the Yucca Mountain Socioeconomic Study is the potential impact of a relatively minor radiation-related accident. A large number of potential impact of a relatively minor radiation-related accident. A large number of potential accident scenarios have been under consideration (such as a transportation or other surface accident which results in a significant decline in tourism, the number of conventions, or the selection of Nevada as a retirement residence). The results of the work in Goiania make it clear, however, that such a significant shift in established social patterns and trends is not likely to occur as a direct outcome of a single nuclear-related accident (even, perhaps, a relatively major one), but rather, are likely to occur as a result of the enduring social interpretations of such an accident -- that is, as a result of the process of understanding, communicating, and socially sustaining a particular set of associations with respect to the initial incident

  14. FMCT verification: Case studies

    International Nuclear Information System (INIS)

    Full text: How to manage the trade-off between the need for transparency and the concern about the disclosure of sensitive information would be a key issue during the negotiations of FMCT verification provision. This paper will explore the general concerns on FMCT verification; and demonstrate what verification measures might be applied to those reprocessing and enrichment plants. A primary goal of an FMCT will be to have the five declared nuclear weapon states and the three that operate unsafeguarded nuclear facilities become parties. One focus in negotiating the FMCT will be verification. Appropriate verification measures should be applied in each case. Most importantly, FMCT verification would focus, in the first instance, on these states' fissile material production facilities. After the FMCT enters into force, all these facilities should be declared. Some would continue operating to produce civil nuclear power or to produce fissile material for non- explosive military uses. The verification measures necessary for these operating facilities would be essentially IAEA safeguards, as currently being applied to non-nuclear weapon states under the NPT. However, some production facilities would be declared and shut down. Thus, one important task of the FMCT verifications will be to confirm the status of these closed facilities. As case studies, this paper will focus on the verification of those shutdown facilities. The FMCT verification system for former military facilities would have to differ in some ways from traditional IAEA safeguards. For example, there could be concerns about the potential loss of sensitive information at these facilities or at collocated facilities. Eventually, some safeguards measures such as environmental sampling might be seen as too intrusive. Thus, effective but less intrusive verification measures may be needed. Some sensitive nuclear facilities would be subject for the first time to international inspections, which could raise concerns

  15. Termination: A Case Study.

    Science.gov (United States)

    Friedberg, Ahron L

    2015-12-01

    In this article I posit and examine certain criteria and qualities for ending an analysis. The case study describes the end phase of a four-year psychoanalysis in which the patient's decision to move to another area forced the end of his analysis. We continued to explore and work through his core neurotic conflicts that included issues of competitive rivalry, dominance and submission, control, and anxiety about birth and death. A shift in the transference from me as a negative father to me as a supportive but competitive older brother was also examined in the context of ending treatment as well as other aspects of the transference. In addition, we analyzed the meaning of his ending treatment based on an extra-analytic circumstance. In discussing this phase of treatment, the definition and history of the term "termination" and its connotations are reviewed. Various criteria for completing an analysis are examined, and technical observations about this phase of treatment are investigated. It was found that while a significant shift in the transference occurred in this phase of the patient's analysis, conflicts related to the transference were not "resolved" in the classical sense. Terminating treatment was considered as a practical matter in which the patient's autonomy and sense of choice were respected and analyzed. PMID:26583444

      Lyric, as a special form of poetry, its translatability has been a controversial focus among both translators and musicians. This thesis analyzes English-Chinese lyric translation by the illustrations of Michael Jackson’s works based on the references of“equivalent theory”, during which Nida’s arguments about equivalence will be employed. The thesis indicates the important roles which“cultural context”and“personal background”play in the process of lyric translation. With the citing examples of Michael Jackson’s works, this thesis demonstrates the significance of the match of the translated text and the music and the rhythm, and tries to give a better version of lyric translation. The purpose of this thesis is to seek the possibility of the equal performance effect of English-Chinese lyric translation.

For the analysis of the issue, we set up the basis of illustrative images, which acted as the test material. It has been shown that visual images serve as the material for the development of visual thinking students are taught to read information, which represents the worksheet, to think and to create something new. The article considers art of graphics pencil using a computer-drawing program with processing in Photoshop. There are mixed techniques (mixed media, based on the use of traditional drawing and herbarium specimen, processed in Photoshop in the color. Another new direction of contemporary agroillustration is infographics. Its using in educational and scientific process is determined by the fact that infographics involves analytical processing of quantitative data obtained during the experiment. On the other hand, the data is needed to visualize, execute and present. A new direction in contemporary agro-botanical illustration is plant images taken with X-rays. The modern level of requirements to create images is high enough and it must be taken into account when carrying out scientific experiments, when it is necessary to demonstrate the object of research results. Modern agroillustration can be processed using various systems of artificial intelligence, pattern recognition, for example, the system named “Edos”

In this article we illustrate how case studies can be used to teach STEM students principles of ethics. PMID:25574280

  12. Theory testing using case studies

    DEFF Research Database (Denmark)

    Dissing Sørensen, Pernille; Løkke Nielsen, Ann-Kristina

    Case studies may have different research goals. One such goal is the testing of small-scale and middle-range theories. Theory testing refers to the critical examination, observation, and evaluation of the 'why' and 'how' of a specified phenomenon in a particular setting. In this paper, we focus on...... the strengths of theory-testing case studies. We specify research paths associated with theory testing in case studies and present a coherent argument for the logic of theoretical development and refinement using case studies. We emphasize different uses of rival explanations and their implications...... for research design. Finally, we discuss the epistemological logic, i.e., the value to larger research programmes, of such studies and, following Lakatos, conclude that the value of theory-testing case studies lies beyond naïve falsification and in their contribution to developing research programmes...

    In the head and neck region, synovial sarcomas (SS) are rare tumours. We describe the diagnostic approach to SS based on two cases which developed in a 26-year-old male in the face and in a 53-year-old female on the alveolar mucosa of the upper jaw. The demographic profile of the patients was compatible with the literature. Histopathologically, both tumours presented as unencapsulated spindle cell tumours arranged into short fascicles. Although the chromosomal translocation of t(X;18)(p11.2;q11.2), transducin-like enhancer of split 1 (TLE-1) and SMARCB1 antibodies derived from gene expression studies are considered as the most sensitive makers to diagnose SS, these facilities were not available. Therefore, our cases were diagnosed as monophasic fibrous SS, utilizing a panel of immunohistochemical markers, including cytokeratins, EMA, Bcl-2, and CD99 as positive indicators and CD34, SMA, MYO-D, and S-100 as negative indicators. PAS staining was used to identify glycogen and to exclude spindle cell carcinomas and leiomyosarcoma, while Alcian blue was used to identify myxoid ground substance and to exclude nodular fasciitis. In conclusion, SS, although rare, should be included in the differential diagnosis of spindle cell tumours of the face and oral mucosa. PMID:27195266

  17. Subsidence over AML and its causes - A case study

    International Nuclear Information System (INIS)

    Subsidence over abandoned mined lands can be attributed to several causes. For purposes of compensation and liability and developing remedial measures, it is essential to identify the real causes. The detailed procedures for a subsidence investigation and the keys to identify and determine the causes and severity of the damages are illustrated and discussed through a case study in this paper. A subsidence check list has been developed for investigation purposes. The case discussed in this paper is a mining-related subsidence. The associated subsidence index was 60%. The damage to the dwelling was due to tension. The major damage was developed within two days. A crackmeter was installed on the exterior wall to monitor the house movement. An inclinometer casing and a Sondex casing were installed in a borehole to monitor the ground movement. The results of the geotechnical instrumentation are presented to illustrate the procedures developed for investigating the subsidence cases over the abandoned mine lands

    Full Text Available Both the 1999 IEA Civic Education Study (CIVED and the 2009 IEA International Civics and Citizenship Education Study (ICCS sought to examine young people’s attitudes and behaviors as related to civic engagement in addition to their civic knowledge. Now that both studies are completed, questions can be asked about the extent to which the averages of outcomes across countries have stayed consistent or changed. The purpose of this article is to review the CIVED and ICCS studies to examine the potential for, and potential limitations to, such a comparison extending beyond the cognitive domain to some attitudinal and participatory outcomes. We compared guiding frameworks for each study, examined the similarities and differences among items in scales appearing in both studies, and provided a general discussion of the pitfalls of comparing IRT scales across cohorts. An item-level analysis explored whether young people’s average attitudes toward immigrants’ rights and institutional trust changed between 1999 and 2009 in five Nordic countries. Stability in support for immigrants’ rights and increasing trust are apparent in most countries, although exceptions to this pattern exist. Recommendations for secondary analysis of CIVED and ICCS are discussed.

  10. Specifying content and mechanisms of change in interventions to change professionals’ practice: an illustration from the Good Goals study in occupational therapy

    Directory of Open Access Journals (Sweden)

    Kolehmainen Niina

    2012-10-01

    Full Text Available Abstract Background It is widely agreed that interventions to change professionals’ practice need to be clearly specified. This involves (1 selecting and defining the intervention techniques, (2 operationalising the techniques and deciding their delivery, and (3 formulating hypotheses about the mechanisms through which the techniques are thought to result in change. Descriptions of methods to achieve these objectives are limited. This paper reports methods and illustrates outputs from a study to meet these objectives, specifically from the Good Goals study to improve occupational therapists’ caseload management practice. Methods (1 Behaviour change techniques were identified and selected from an existing matrix that maps techniques to determinants. An existing coding manual was used to define the techniques. (2 A team of occupational therapists generated context-relevant, acceptable modes of delivery for the techniques; these data were compared and contrasted with previously collected data, literature on caseload management, and the aims of the intervention. (3 Hypotheses about the mechanisms of change were formulated by drawing on the matrix and on theories of behaviour change. Results (1 Eight behaviour change techniques were selected: goal specified; self-monitoring; contract; graded tasks; increasing skills (problem solving, decision making, goal setting; coping skills; rehearsal of relevant skills; social processes of encouragement, support, and pressure; demonstration by others; and feedback. (2 A range of modes of delivery were generated (e.g., graded tasks’ consisting of series of clinical cases and situations that become increasingly difficult. Conditions for acceptable delivery were identified (e.g., ‘self-monitoring’ was acceptable only if delivered at team level. The modes of delivery were specified as face-to-face training, task sheets, group tasks, DVDs, and team-based weekly meetings. (3 The eight techniques were

  11. Guidelines for Conducting Positivist Case Study Research in Information Systems

    Directory of Open Access Journals (Sweden)

    Graeme Shanks

    2002-11-01

    Full Text Available The case study research approach is widely used in a number of different ways within the information systems community. This paper focuses on positivist, deductive case study research in information systems. It provides clear definitions of important concepts in positivist case study research and illustrates these with an example research study. A critical analysis of the conduct and outcomes of two recently published positivist case studies is reported. One is a multiple case study that validated concepts in a framework for viewpoint development in requirements definition. The other is a single case study that examined the role of social enablers in enterprise resource planning systems implementation. A number of guidelines for successfully undertaking positivist case study research are identified including developing a clear understanding of key concepts and assumptions within the positivist paradigm; providing clear and unambiguous definitions of the units and interactions when using any theory; carefully defining the boundary of the theory used in the case study; using hypotheses rather than propositions in the empirical testing of theory; using fuzzy or probabilistic propositions in recognising that reality can never be perfectly known; selecting case studies carefully, particularly single case studies; and recognising that generalisation from positivist, single case studies is inherently different from generalisation from single experiments. When properly undertaken, positivist, deductive case study research is a valuable research approach for information systems researchers, particularly when used within pluralist research programs that use a number of different research approaches from different paradigms.

    Fruit is an assimilator of metabolites, nutrients, and signaling molecules, thus considered as potential target for pathogen attack. In response to patho-stress, such as fungal invasion, plants reorganize their proteome, and reconfigure their physiology in the infected organ. This remodeling is coordinated by a poorly understood signal transduction network, hormonal cascades, and metabolite reallocation. The aim of the study was to explore organ-based proteomic alterations in the susceptibility of heterotrophic fruit to necrotrophic fungal attack. We conducted time-series protein profiling of Sclerotinia rolfsii invaded tomato (Solanum lycopersicum) fruit. The differential display of proteome revealed 216 patho-stress responsive proteins (PSRPs) that change their abundance by more than 2.5-fold. Mass spectrometric analyses led to the identification of 56 PSRPs presumably involved in disease progression; regulating diverse functions viz. metabolism, signaling, redox homeostasis, transport, stress-response, protein folding, modification and degradation, development. Metabolome study indicated differential regulation of organic acid, amino acids, and carbohydrates paralleling with the proteomics analysis. Further, we interrogated the proteome data using network analysis that identified two significant functional protein hubs centered around malate dehydrogenase, T-complex protein 1 subunit gamma, and ATP synthase beta. This study reports, for the first-time, kinetically controlled patho-stress responsive protein network during post-harvest storage in a sink tissue, particularly fruit and constitute the basis toward understanding the onset and context of disease signaling and metabolic pathway alterations. The network representation may facilitate the prioritization of candidate proteins for quality improvement in storage organ. PMID:27507973

    Everyone in science should have ethics education training. I have seen graduate students taken advantage of by their mentors. Many of us have seen misconduct...but what should we do about it? Young scientists are often unaware of the rules in science and make mistakes because of their ignorance of the rules in that particular field of study. Then there are an increasing number of cases in the news of overt cases of misrepresentation in science. All are welcome to attend this discussion of case studies. A case study on topics such as: how to treat data properly, how our values in science affect our work, who gets authorship on scientific papers, who is first author on a paper, what you should do if you uncover misconduct or plagiarism in your university, and we will discuss the scientist's role in society.

    Breaking the students into small, collaborative learning groups to solve a meaningful task together is one of the most successful and fully evaluated teaching techniques implemented over the last century. Although there are many ways to accomplish small group learning, a long-standing and consistently successful collaborative class activity is to use the case study teaching strategy. The use of case studies is common in medical schools and law schools, but not so common in the teaching of astronomy. Case studies create meaningful conversations among students and with the professor by focusing on life-like dilemmas to be solved. Case study tasks ask audience members to synthesize several ideas or evaluate scenarios that have not been explicitly presented to them in the lecture or in available readings.

    The Socratic function of single case studies (SCSs) is described in its relation to the problem of scientific theory development. Contrary to the traditional point of view, the single case study is not a demonstration or verification of theoretical concepts, but a method of their generation and opportunity for analysis of their interrelations. Considering the case study from the perspective of the Socratic function brings to light important conclusions about the ecological validity of theory development.

    Pattern approach to the diagnosis of lung diseases based on CT scan appearances. Guide to quick and reliable differential diagnosis. CT-pathology correlation. Emphasis on state-of-the-art MDCT. The purpose of this atlas is to illustrate how to achieve reliable diagnoses when confronted by the different abnormalities, or ''disease patterns'', that may be visualized on CT scans of the chest. The task of pattern recognition has been greatly facilitated by the advent of multidetector CT (MDCT), and the focus of the book is very much on the role of state-of-the-art MDCT. A wide range of disease patterns and distributions are covered, with emphasis on the typical imaging characteristics of the various focal and diffuse lung diseases. In addition, clinical information relevant to differential diagnosis is provided and the underlying gross and microscopic pathology is depicted, permitting CT-pathology correlation. The entire information relevant to each disease pattern is also tabulated for ease of reference. This book will be an invaluable handy tool that will enable the reader to quickly and easily reach a diagnosis appropriate to the pattern of lung abnormality identified on CT scans.

  4. Use of real-time three-dimensional transesophageal echocardiography in type A aortic dissections: Advantages of 3D TEE illustrated in three cases

    2015-01-01

    Full Text Available Stanford type A aortic dissections often present to the hospital requiring emergent surgical intervention. Initial diagnosis is usually made by computed tomography; however transesophageal echocardiography (TEE can further characterize aortic dissections with specific advantages: It may be performed on an unstable patient, it can be used intra-operatively, and it has the ability to provide continuous real-time information. Three-dimensional (3D TEE has become more accessible over recent years allowing it to serve as an additional tool in the operating room. We present a case series of three patients presenting with type A aortic dissections and the advantages of intra-operative 3D TEE to diagnose the extent of dissection in each case. Prior case reports have demonstrated the use of 3D TEE in type A aortic dissections to characterize the extent of dissection and involvement of neighboring structures. In our three cases described, 3D TEE provided additional understanding of spatial relationships between the dissection flap and neighboring structures such as the aortic valve and coronary orifices that were not fully appreciated with two-dimensional TEE, which affected surgical decisions in the operating room. This case series demonstrates the utility and benefit of real-time 3D TEE during intra-operative management of a type A aortic dissection.

  6. Case studies in Bayesian microbial risk assessments

    Directory of Open Access Journals (Sweden)

    Turner Joanne

    2009-12-01

    Full Text Available Abstract Background The quantification of uncertainty and variability is a key component of quantitative risk analysis. Recent advances in Bayesian statistics make it ideal for integrating multiple sources of information, of different types and quality, and providing a realistic estimate of the combined uncertainty in the final risk estimates. Methods We present two case studies related to foodborne microbial risks. In the first, we combine models to describe the sequence of events resulting in illness from consumption of milk contaminated with VTEC O157. We used Monte Carlo simulation to propagate uncertainty in some of the inputs to computer models describing the farm and pasteurisation process. Resulting simulated contamination levels were then assigned to consumption events from a dietary survey. Finally we accounted for uncertainty in the dose-response relationship and uncertainty due to limited incidence data to derive uncertainty about yearly incidences of illness in young children. Options for altering the risk were considered by running the model with different hypothetical policy-driven exposure scenarios. In the second case study we illustrate an efficient Bayesian sensitivity analysis for identifying the most important parameters of a complex computer code that simulated VTEC O157 prevalence within a managed dairy herd. This was carried out in 2 stages, first to screen out the unimportant inputs, then to perform a more detailed analysis on the remaining inputs. The method works by building a Bayesian statistical approximation to the computer code using a number of known code input/output pairs (training runs. Results We estimated that the expected total number of children aged 1.5-4.5 who become ill due to VTEC O157 in milk is 8.6 per year, with 95% uncertainty interval (0,11.5. The most extreme policy we considered was banning on-farm pasteurisation of milk, which reduced the estimate to 6.4 with 95% interval (0,11. In the second

  9. The use of case studies in teaching undergraduate neuroscience.

    Science.gov (United States)

    Meil, William M

    2007-01-01

    Case studies have been the cornerstone of many discoveries in neurology and continue to be an indispensable source of knowledge. Attaching a name, face, and story to the study of neurological disorders makes them more "real" and memorable. This article describes the value of the case study methodology and its advantages as a pedagogical approach. It also illustrates how the seminal case of H.M. can be used to highlight the advantages and disadvantages of the case study methodology. Three exercises are described for incorporating case studies into neuroscience courses. The first exercise requires students to conduct a literature review regarding their assigned case and then design an experiment to address a lingering question regarding that neurological disorder. Survey results of 90 students provide quantitative and qualitative support for this approach. The vast majority of students indicated this exercise was a valuable learning experience; sparked interest in the topic and in biopsychology; increased their knowledge and stimulated critical thinking. The second exercise discusses how students might conduct their own case studies. The third exercise emphasizes the use of case studies as a platform to examine competing hypotheses regarding neurological conditions and their treatment. A table listing case studies appropriate for undergraduate neuroscience courses is included. Cases are categorized by the type of neurological disorder and notes regarding the nature of and content of each case are provided. PMID:23493154

  18. Carbon pricing and energy efficiency improvement - why to miss the interaction for developing economies? An illustrative CGE based application to the Pakistan case

    International Nuclear Information System (INIS)

    Carbon/energy taxes and energy efficiency improvement are studied well in the recent years for their potential adverse impacts on economy, especially for lost production and international competitiveness, and rebound effects. However, little attention has been paid to investigate them jointly, which can not only prevent fall of energy services cost and thereby rebound effect but reduce the associated macroeconomic costs. This study thus employs a 20 sector CGE model to explore separately the impacts of carbon tax and its coordinated implementation with energy efficiency improvement on the Pakistan economy. The country underwent enormous pressure of energy security issues as well as climate change fallouts in the last couple of years and can be regarded as a suitable candidate for energy/environmental conservation policies to be considered at a broader context with more concrete efforts. The simulation results show that the impact of carbon tax on GDP is negative but resulting reductions in pollutant emissions are relatively high. Moreover, the GDP is expected to grow comparatively positive when analyzed with improvements in energy efficiency, with even higher decline in energy consumption demand and so emissions. This simultaneous economic and environmental improvement would thus have positive implications regarding sustainable development of the country. - Highlights: • Carbon tax and energy efficiency progress possibly cause GDP loss and rebound effects. • The interaction of the two policy measures can reduce these unintended effects. • The impact of CT for Pakistan found fairly moderate with high emissions reduction. • Coordinated implementation approach further lower GDP loss with less energy demand. • CT showed potential of reducing emissions of local pollutants even at a higher rate

    Full Text Available This is a report of a case study on 234 patients with impetigo who referred to Razi Dermatology Hospital from April to November, 1989. Treatment was started immediately after obtaining direct smear and performing culture and antibiotic sensitivity test. The most common organism responsible for impetigo was the coagulase-positive staphylococcus (71%. In 13.7% of the cases, the coagulase-negative staphylococcus was grown on culture media, but none of the cultures showed streptococcus as the main organism. Treatment was started with oral penicillin V, oral erythromycin, benzathine penicillin G injection, oral cephalexin, and topical fuccidin. Clinical and bacteriological evaluation after 3-7 days showed that it is preferable to use oral cephalexin instead of other protocols such as oral erythromycin, which has previously been the drug of choice for impetigo. In addition, topical fuccidin with a 75% curative rate was the first drug for treatment, with the same effect as the oral cephalexin

In this context, all nodes were under the system designer’s control, faithfully executing the programmed behaviour. However, today’s networks are often characterized by a free aggregation of nodes. Thus, the possibility increases that a selfish party operates a node, which may violate the collaborative protocol in order to increase a personal...

    In facing the challenges that confront Catholic health care today, it is important to know which civil law forms will assist in preserving the Church's ministry. The proper meshing of civil law and canon law thus provides a vehicle to strengthen the apostolate's work. The case studies presented here suggest several means of applying the principles in the new Code of Canon Law to three potentially problematic situations: the merger of a Catholic and non-Catholic hospital, the leasing of a Catholic hospital to an operating company, and the use of the multicorporate format.

    2005-05-01

    Background: There has been much debate concerning the most suitable protocol for parathyroid scintigraphy; the merits of various radiopharmaceuticals versus the correct imaging protocol to visualise both ectopic and anatomically placed adenomas against the various equipment choices have been debated. Aim: To demonstrate, through the use of a case study, the necessity of changing imaging protocols for parathyroid scintigraphy where a definitive imaging diagnosis is absent in the face of strong clinical suspicion. Method: Use is made of Tc99mMIBI, full field chest scintigraphy, a clearly defined imaging protocol and SPECT imaging to locate ectopic parathyroid tissue in a female patient with significant symptoms of parathyroid hyperfunction. Results: A single hyperfunctioning adenoma is located in the pre-carinal area of the mediastinum. Using a radioguided surgical technique the hyperfunctioning tissue is excised and confirmed by histopathology. Conclusion: Whilst a dramatic reduction in patient symptoms was not seen immediately in this patient, the symptoms of the illness have been subsiding since January 2003. This case study demonstrates the necessity of changing imaging protocols for parathyroid scintigraphy where a definitive imaging diagnosis is absent in the face of strong clinical suspicion.

  13. Illustrating the practice of statistics

    Energy Technology Data Exchange (ETDEWEB)

    Hamada, Christina A [Los Alamos National Laboratory; Hamada, Michael S [Los Alamos National Laboratory

    2009-01-01

    The practice of statistics involves analyzing data and planning data collection schemes to answer scientific questions. Issues often arise with the data that must be dealt with and can lead to new procedures. In analyzing data, these issues can sometimes be addressed through the statistical models that are developed. Simulation can also be helpful in evaluating a new procedure. Moreover, simulation coupled with optimization can be used to plan a data collection scheme. The practice of statistics as just described is much more than just using a statistical package. In analyzing the data, it involves understanding the scientific problem and incorporating the scientist's knowledge. In modeling the data, it involves understanding how the data were collected and accounting for limitations of the data where possible. Moreover, the modeling is likely to be iterative by considering a series of models and evaluating the fit of these models. Designing a data collection scheme involves understanding the scientist's goal and staying within hislher budget in terms of time and the available resources. Consequently, a practicing statistician is faced with such tasks and requires skills and tools to do them quickly. We have written this article for students to provide a glimpse of the practice of statistics. To illustrate the practice of statistics, we consider a problem motivated by some precipitation data that our relative, Masaru Hamada, collected some years ago. We describe his rain gauge observational study in Section 2. We describe modeling and an initial analysis of the precipitation data in Section 3. In Section 4, we consider alternative analyses that address potential issues with the precipitation data. In Section 5, we consider the impact of incorporating additional infonnation. We design a data collection scheme to illustrate the use of simulation and optimization in Section 6. We conclude this article in Section 7 with a discussion.

    2007-10-01

    We selected three case studies to illustrate environmental injustice issues in the South. These examples relate to migrant agricultural workers, the maquiladora industry and artisanal mining, while reviewing some of the major mechanisms involved, e.g. multinational corporations, the development of free trade zones, multilateral free trade agreements and the export of hazards. A series of strategies are discussed in order to address environmental injustice and health disparities that exist on a global scale. Some of the recommendations involve policy initiatives; others, such as research and mentorship, fall within the traditional domain of public health practice. In this paper, special attention is given to concerned environmental and occupational health professionals using evidence-based data for advocacy. For lasting changes to be made, however, stronger institutions and legislation are required. Those who have the 'right to know' about environmental injustice issues include communities of concern, workers' representatives and lawyers. Government officials and company officials may eventually work on the basis of conflict resolution, compensation and remediation, to quote some examples. Systematic approaches to protect both the environment and public health must be updated.

  15. Hybrid Risk Management Methodology: A Case Study

    Directory of Open Access Journals (Sweden)

    Jacky Siu-Lun Ting

    2009-10-01

    Full Text Available Risk management is a decision-making process involving considerations of political, social, economic and engineering factors with relevant risk assessments relating to a potential hazard. In the last decade, a number of risk management tools are introduced and employed to manage and minimize the uncertainty and threats realization to the organizations. However, the focus of these methodologies are different; in which companies need to adopt various risk management principles to visualize a full picture of the organizational risk level. Regarding to this, this paper presents a new approach of risk management that integrates Hierarchical Holographic Modeling (HHM, Enterprise Risk Management (ERM and Business Recovery Planning (BCP for identifying and assessing risks as well as managing the consequences of realized residual risks. To illustrate the procedures of the proposed methodology, a logistic company ABC Limited is chosen to serve as a case study Through applying HHM and ERM to investigate and assess the risk, ABC Limited can be better evaluated the potential risks and then took the responsive actions (e.g. BCP to handle the risks and crisis in near future.

  19. Variables with time-varying effects and the Cox model: Some statistical concepts illustrated with a prognostic factor study in breast cancer

    Directory of Open Access Journals (Sweden)

    Brouste Véronique

    2010-03-01

    Full Text Available Abstract Background The Cox model relies on the proportional hazards (PH assumption, implying that the factors investigated have a constant impact on the hazard - or risk - over time. We emphasize the importance of this assumption and the misleading conclusions that can be inferred if it is violated; this is particularly essential in the presence of long follow-ups. Methods We illustrate our discussion by analyzing prognostic factors of metastases in 979 women treated for breast cancer with surgery. Age, tumour size and grade, lymph node involvement, peritumoral vascular invasion (PVI, status of hormone receptors (HRec, Her2, and Mib1 were considered. Results Median follow-up was 14 years; 264 women developed metastases. The conventional Cox model suggested that all factors but HRec, Her2, and Mib1 status were strong prognostic factors of metastases. Additional tests indicated that the PH assumption was not satisfied for some variables of the model. Tumour grade had a significant time-varying effect, but although its effect diminished over time, it remained strong. Interestingly, while the conventional Cox model did not show any significant effect of the HRec status, tests provided strong evidence that this variable had a non-constant effect over time. Negative HRec status increased the risk of metastases early but became protective thereafter. This reversal of effect may explain non-significant hazard ratios provided by previous conventional Cox analyses in studies with long follow-ups. Conclusions Investigating time-varying effects should be an integral part of Cox survival analyses. Detecting and accounting for time-varying effects provide insights on some specific time patterns, and on valuable biological information that could be missed otherwise.

    Full Text Available Post stroke rehabilitation has been consistently reported in physiotherapy as being difficult to manage and limiting to rehabilitation outcome. It is reported that the first few months post stroke are crucial for rehabilitation to reach a maximum potential. However, after this period further recovery is unlikely. Specific, measurable, achievable, realistic, and time-framed (SMART goals are used for goal setting for rehabilitation. They can provide coordination between a multidisciplinary team to develop a plan for the individual needs of patients. This case study explored the use of SMART goals, which are often not used in a rehabilitation setting due to being time-consuming and difficult to create. This case report provides the first evidence that SMART goals may serve as a powerful tool for rehabilitation following stroke. The case study illustrates the clinical role of physiotherapists in the management of a patient with stroke. [J Exp Integr Med 2014; 4(1.000: 71-73

    2014-01-01

    Full Text Available Concentrated Photovoltaics (CPV, once a niche technology, has now reached the maturity and reliability for large scale power generation. Especially in regions where temperatures are very high, the use of high efficiency triple junction solar cells with concentrating optics allows stable energy yield. Thus CPV can be seen as complementary and not in concurrence with silicon photovoltaics. The state of the art, the advantages and limitations of this technology will be shown. Among the main advantages of CPV is the possibility of a much higher energy supply, when compared to silicon photovoltaics, both comparing CPV and silicon with same area or the same installed power. The use of recycled and recyclable materials allows a more environmentally friendly production. The possibility to couple CPV with desalination facilities, energy storage will be analysed. As an example a case study of a CPV installation in Northern Italy is discussed. Here the use of mature technologies, derived from automotive and lighting sectors resulted in a simple and efficient module.

    Concentrated Photovoltaics (CPV), once a niche technology, has now reached the maturity and reliability for large scale power generation. Especially in regions where temperatures are very high, the use of high efficiency triple junction solar cells with concentrating optics allows stable energy yield. Thus CPV can be seen as complementary and not in concurrence with silicon photovoltaics. The state of the art, the advantages and limitations of this technology will be shown. Among the main advantages of CPV is the possibility of a much higher energy supply, when compared to silicon photovoltaics, both comparing CPV and silicon with same area or the same installed power. The use of recycled and recyclable materials allows a more environmentally friendly production. The possibility to couple CPV with desalination facilities, energy storage will be analysed.

  20. Hepatocellular carcinoma: illustrated guide to systematic radiologic diagnosis and staging according to guidelines of the American Association for the Study of Liver Diseases.

    LENUS (Irish Health Repository)

    McEvoy, Sinead H

    2013-10-01

    Hepatocellular carcinoma is a malignancy that predominantly occurs in the setting of cirrhosis. Its incidence is rising worldwide. Hepatocellular carcinoma differs from most malignancies because it is commonly diagnosed on the basis of imaging features alone, without histologic confirmation. The guidelines from the American Association for the Study of Liver Diseases (AASLD) are a leading statement for the diagnosis and staging of hepatocellular carcinoma, and they have recently been updated, incorporating several important changes. AASLD advocates the use of the Barcelona Clinic Liver Cancer (BCLC) staging system, which combines validated imaging and clinical predictors of survival to determine stage and which links staging with treatment options. Each stage of the BCLC system is outlined clearly, with emphasis on case examples. Focal liver lesions identified at ultrasonographic surveillance in patients with cirrhosis require further investigation. Lesions larger than 1 cm should be assessed with multiphasic computed tomography or magnetic resonance imaging. Use of proper equipment and protocols is essential. Lesions larger than 1 cm can be diagnosed as hepatocellular carcinoma from a single study if the characteristic dynamic perfusion pattern of arterial hyperenhancement and venous or delayed phase washout is demonstrated. If the imaging characteristics of hepatocellular carcinoma are not met, the alternate modality should be performed. Biopsy should be used if neither modality is diagnostic of hepatocellular carcinoma. Once the diagnosis has been made, the cancer should be assigned a BCLC stage, which will help determine suitable treatment options. Radiologists require a systematic approach to diagnose and stage hepatocellular carcinoma with appropriate accuracy and precision.

    Currently in the United States, the heavy majority of plug-in electric vehicle (PEV) sales have been in highly conducive, selected, metropolitan areas; opposed to more broad distribution across the country. The U.S. Department of Energy’s EV Everywhere Grand Challenge is looking carefully at the barriers and opportunities that exist to enable small and midsize communities to partake in the PEV market and benefit from the economic and environmental advantages of PEVs. In order to gain insight into these challenges and barriers, DOE selected a success story (i.e., Drive Electric Vermont) as the subject of this case study, as the state of Vermont is tied with Detroit, Michigan in having the highest percentage of 2014 (most recent complete data) PEV registrations for cold weather U.S. cities and has seen more than a sixfold increase in charging stations over the last three years. The overall objective of this case study was to use the lessons learned from Drive Electric Vermont to determine what activities are most effective at encouraging acquisitions of PEVs and deployment of charging infrastructure in small to midsize communities, prioritizing and sequencing their implementation, identifying robust means for extrapolation, and applying this understanding to other small to midsize communities across the nation. The Drive Electric Vermont Program was formed in 2012 with a goal of increasing the use of electrified transportation in Vermont through policy development, education and outreach, and infrastructure development. The Drive Electric Vermont Program can be broadly broken into four components: (1) strategic planning/leadership, (2) stakeholder/partnership development, (3) education and outreach, and (4) incentives. The early phases of the program focused heavily on strategic planning, and stakeholder and partnership development, followed by a transition to education and outreach activities, charging infrastructure development, and grant and incentive programs

  4. Managing Residual Contaminants Reuse and Isolation Case Studies

    International Nuclear Information System (INIS)

    Contaminants remaining on sites after regulatory-approved environmental remediation operations are complete represent continued risk to human health and the environment. Many sites require continued management efforts to: (1) protect the integrity of the engineered remedy/control, (2) limit the exposure of individuals to residual contamination by limiting reuse activities, (3) maintain ready access to accurate records/information, and (4) protect against vulnerabilities from intentional threats/actions. This paper presents performance information from selected case studies to provide insight into various management approaches employed for addressing the risks associated with residual contaminants. The case studies involve sites remediated within the U.S. CERCLA framework, and illustrate two prevailing management approaches for addressing the risks. Sacrifice Zones are sites that are purposefully isolated to prevent human access onto the property. Reuse Sites provide limited access for specific use

    Sassoon, A A; Barrack, R L

    2016-06-01

    The use of large-diameter metal-on-metal (MoM) components in total hip arthroplasty (THA) is associated with an increased risk of early failure due to adverse local tissue reaction to metal debris (ARMD) in response to the release of metal ions from the bearing couple and/or head-neck taper corrosion. The aim of this paper was to present a review of the incidence and natural history of ARMD and the forms of treatment, with a focus on the need for and extent of resection or debulking of the pseudotumour. An illustrative case report is presented of a patient with an intra-pelvic pseudotumour associated with a large diameter MoM THA, which was treated successfully with revision of the bearing surface to a dual mobility couple and retention of the well-fixed acetabular and femoral components. The pseudotumour was left in situ Resolution of the intra-pelvic mass and normalisation of metal ion levels was observed seven months post-operatively.

    1999-01-01

    Full Text Available Systems analysis students seldom experience the practical difficulties of the initial investigation into a client’s requirements. They get little chance to practice the skills they need to investigate complex and confused problem situations, or to appreciate the wider organizational issues that can impact on a situation. This teaching case is designed to give students the opportunity to practice and apply investigation skills and to challenge them to consider the wider work environment when considering possible solutions to a problem situation. The case is conducted as a role-play, with students acting as systems analysts and teaching staff role-playing the clients. The students develop a report analyzing the client’s situation based on the issues that arise during the interviews. Feed-back sessions focus on discussing how well the students applied various interviewing strategies previously covered in lectures, and on the wider organizational problems that could impact proposed information system solutions.

    2014-04-01

    In the area of fixed prosthodontics, implants have evolved to become the gold standard in terms of longevity and esthetic outcome (1). As in all of dentistry, careful diagnosis and treatment planning is a must to achieve an optimum result. When evaluating the recipient site, one must determine if any type of defect (hard or soft tissue) exists which would require augmentation. The existing occlusion must also be evaluated to ensure the dentist is aware of possible prosthetic complications. In straightforward cases, such as those without the need for augmentation, the conventional timeline requires a waiting period of 3 months following surgical placement to begin the restorative procedures. Factoring in the restorative time frame, the patient may wait up to approximately 4 months for the final implant prosthesis. Various advancements in dentistry are changing the way dentists approach implant dentistry--from diagnosis and treatment planning to final restorations. This article illustrates these advances through a case study. PMID:24937892

    2010-01-01

    One of the rarest situations regarding an adrenal incidentaloma is an adrenal cyst. We present the case of a 61-year-old male patient diagnosed with peritonitis. During surgery, a right adrenal tumor of 2 cm is discovered. The patient was referred to endocrinology. 6 months later the diameter of the tumor is 7 times bigger than the initial stage. It has no secretory phenotype, except for the small increase of serum aldosterone and the 24-h 17-ketosteroids. Open right adrenalectomy is performed and a cyst of 15 cm is removed. The evolution after surgery is good. The pathological exam reveals an adrenal cyst with calcifications and osteoid metaplasia. The immunohistochemistry showed a positive reaction for CD34 and ACT in the vessels and VIM in the stroma. The adrenal cysts are not frequent and represent a challenge regarding the preoperative diagnostic and surgical procedure of resection. The pathological exam highlights the major aspects.

    Dann, O T

    1977-01-01

    The psychoanalytic references to embarrassment are reviewed. Embarrassment, in the literature, is seen largely as an affect involving exhibitionistic and scopophilic conflicts and defenses against these. A case in which embarrassment was prominent is discussed. Embarrassment in the patient was an ego response which implied an external object for its manifestation. It involved exhibitionistic and scopophilic conflicts and projective defenses, but also operated in ego-gratifying and adaptive ways. Her embarrassment was understood through the analysis of an initial embarrassing dream of nakedness and other dreams and associated material as the defensive out-grouth of repeated exposures to the primal scene. Embarrassment was a resistance to remembering in the analysis, and the primal-scene experiences were partially reconstructed. The analytic situation was, in many ways, a symbolic re-creation of the primal scene, including the patient's response of embarrassment. The development of embarrassment in the patient's childhood was furthered and confirmed by its being an identification with the attitudes of both parents. Finally, some reflections on embarrassment and shame in its various forms are set forth. PMID:560404

    The multifamily case studies that are the subject of this report were conducted to provide a better understanding of the approach taken by program operators in weatherizing large buildings. Because of significant variations in building construction and energy systems across the country, five states were selected based on their high level of multifamily weatherization. This report summarizes findings from case studies conducted by multifamily weatherization operations in five cities. The case studies were conducted between January and November 1994. Each of the case studies involved extensive interviews with the staff of weatherization subgrantees conducting multifamily weatherization, the inspection of 4 to 12 buildings weatherized between 1991 and 1993, and the analysis of savings and costs. The case studies focused on innovative techniques which appear to work well.

    The aim of this study is to provide an overview of the scientific activity of different psychoanalytic schools of thought in terms of the content and production of case studies published on ISI Web of Knowledge. Between March 2013 and November 2013, we contacted all case study authors included in the online archive of psychoanalytic and psychodynamic case studies (www.singlecasearchive.com) to inquire about their psychoanalytic orientation during their work with the patient. The response rate for this study was 45%. It appears that the two oldest psychoanalytic schools, Object-relations psychoanalysis and Ego psychology or “Classical psychoanalysis” dominate the literature of published case studies. However, most authors stated that they feel attached to two or more psychoanalytic schools of thought. This confirms that the theoretical pluralism in psychoanalysis stretches to the field of single case studies. The single case studies of each psychoanalytic school are described separately in terms of methodology, patient, therapist, or treatment features. We conclude that published case studies features are fairly similar across different psychoanalytic schools. The results of this study are not representative of all psychoanalytic schools, as some do not publish their work in ISI ranked journals. PMID:26483725

    Full Text Available This paper describes the potential suitability of case study methodology for inquiry with the homeless population. It references a research study that uses case study research method to build theory. This study's topic is the lived experience of destitute individuals who reside in homeless shelters, and explores the homeless shelter built environment's potential influence on resident satisfaction and recovery. Case study methodology may be appropriate because it explores real-life contextual issues that characterize homelessness and can also accommodate the wide range of homeless person demographics that make this group difficult to study in a generalized fashion. Further, case study method accommodates the need within research in this area to understand individualized treatments as a potential solution for homelessness.

    Full Text Available The current study described a single child’s language acquisition. The importance of this study resided in the circumstances and the environment in which the child lived. He came from a family in which the parents were from different countries and cultures; spoke different Arabic dialects and who lived in a country in which English is spoken. The child was in his critical period of language acquisition. He seemed to have established a unique way of communicating with people surrounding him to cope with all the linguistic varieties around him. The study showed that the child had semantic, syntactic and morphological overgeneralized structures. The data and results showed that overgeneralization and language acquisition were primarily an innate faculty of the human mind and that imitation did played a primary role in language acquisition.It showed, nevertheless, that imitation and behaviorist approaches could not fully account for language acquisition nor did the generative approach. The results went in favor of an Emergentist approach of language acquisition where both innateness and imitations were crucial constituents of children’s acquisition of linguistic forms.

  14. On combining family and case-control studies.

    Science.gov (United States)

    Pfeiffer, Ruth M; Pee, David; Landi, Maria T

    2008-11-01

    Studies to detect genetic association with disease can be family-based, often using families with multiple affected members, or population based, as in population-based case-control studies. If data on both study types are available from the same population, it is useful to combine them to improve power to detect genetic associations. Two aspects of the data need to be accommodated, the sampling scheme and potential residual correlations among family members. We propose two approaches for combining data from a case-control study and a family study that collected families with multiple cases. In the first approach, we view a family as the sampling unit and specify the joint likelihood for the family members using a two-level mixed effects model to account for random familial effects and for residual genetic correlations among family members. The ascertainment of the families is accommodated by conditioning on the ascertainment event. The individuals in the case-control study are treated as families of size one, and their unconditional likelihood is combined with the conditional likelihood for the families. This approach yields subject specific maximum likelihood estimates of covariate effects. In the second approach, we view an individual as the sampling unit. The sampling scheme is accommodated using two-phase sampling techniques, marginal covariate effects are estimated, and correlations among family members are accounted for in the variance calculations. The models are compared in simulations. Data from a case-control and a family study from north-eastern Italy on melanoma and a low-risk melanoma-susceptibility gene, MC1R, are used to illustrate the approaches. PMID:18454494

    Full Text Available This research reviews the literature on case study as a strategic qualitative research methodology. Although case studies have been criticised by some authors as lacking scientific rigour and do not address generalizability, this research, however, reiterated its appropriateness when dealing with a process or a complex real-life activities in great-depth. Case study has been commonly used in social science fields like sociology, industrial relations and anthropology eventhough generally was considered an underutilized strategy. Hence, this research explained the general concept of a case study, strengths and weaknesses of using this method knowing that theoretically case is exciting and data rich. Based on a study of four organizations and the researcher’s own experience, this article described matters on how case study was undertaken, gaining excess to those organizations and the systematic process of data collection and triangulation (multiple techniques. It was noted that combining multiple techniques for elicitng data in case study research actually strengthens and confirmed results.

    1982-09-01

    A small change in brick dimensions resulted in an increase in the perceived work-load of men loading and unloading pallets of bricks by hand. A laboratory study indicated that the change in brick dimensions required changes in grip pattern in order to unload bricks at the same rate, moving the same number at a time. These changed grip patterns resulted in increased upper body movement, increased chest-muscle activity and higher heart rates. These differences were reflected in higher subjective ratings of fatigue. PMID:15676442

    Full Text Available Modern educational technologies are based on competence approach and focus on the future professional activity. Case study is one of the most significant technologies in modern higher education. The basic concepts used in the case study method are a “situation” and an “analysis”, as well as their derivative - “analysis of the situation”. The case study method of is one of the best tools for gaining experience, as it investigates practical situations that occur in managerial job. It combines theoretical knowledge with the analysis of the actual practical experience in accordance with a major. Doing case studies students read the description of the situation and offer divergent projects of managerial decisions that could be used by real managers dealing with the problem posed by the case study author. Answers to the questions posed in the case description are not given, as a rule, since the main purpose in the case analysis is to organize a discussion in the classroom or provoke speculations of those who do the self-study.

  5. Teaching Mathematical Modelling for Earth Sciences via Case Studies

    Science.gov (United States)

    Yang, Xin-She

    2010-05-01

    Mathematical modelling is becoming crucially important for earth sciences because the modelling of complex systems such as geological, geophysical and environmental processes requires mathematical analysis, numerical methods and computer programming. However, a substantial fraction of earth science undergraduates and graduates may not have sufficient skills in mathematical modelling, which is due to either limited mathematical training or lack of appropriate mathematical textbooks for self-study. In this paper, we described a detailed case-study-based approach for teaching mathematical modelling. We illustrate how essential mathematical skills can be developed for students with limited training in secondary mathematics so that they are confident in dealing with real-world mathematical modelling at university level. We have chosen various topics such as Airy isostasy, greenhouse effect, sedimentation and Stokes' flow,free-air and Bouguer gravity, Brownian motion, rain-drop dynamics, impact cratering, heat conduction and cooling of the lithosphere as case studies; and we use these step-by-step case studies to teach exponentials, logarithms, spherical geometry, basic calculus, complex numbers, Fourier transforms, ordinary differential equations, vectors and matrix algebra, partial differential equations, geostatistics and basic numeric methods. Implications for teaching university mathematics for earth scientists for tomorrow's classroom will also be discussed. Refereces 1) D. L. Turcotte and G.

  6. Conservation vs. renewable energy: Cases studies from Hawaii

    International Nuclear Information System (INIS)

    State of Hawaii generates about 90 percent of its electricity from imported fossil fuel sources. Thus, there is pressure from both public and policy makers to reduce the State dependency on foreign fossil fuel sources. To this extend, there are incentives created at State and Federal level for both residential and commercial buildings to install photovoltaic (PV) systems. Although such incentives are necessary for long-term objectives, it is shown in this study that retrofitting inefficient old building-equipment is another viable source to reduce the State of Hawaii's electricity demand. Four case studies are presented to illustrate that building-equipment retrofitting is a viable and necessary tool for increasing the energy efficiency of buildings. Each case study presents an equipment retrofit project electricity savings with its payback periods, and compares with equivalent electricity capacity and economics PV systems in Honolulu, Hawaii. The case studies show that energy savings from retrofit projects ranged from 28% to 61% for individual equipment retrofits. These results indicate that equipment retrofitting with energy-efficient alternatives is about 50% or more cost-effective than installing PV systems. This is so even when large renewable energy tax incentives provided by the Federal and State Governments are taken into account.

    International Nuclear Information System (INIS)

    Full text: A forty-two-year-old male presented to the Royal Adelaide Hospital with symptoms of increasing shortness of breath, swelling in both ankles, petechial rash and blood in his sputum. Initial investigations showed cardiomegaly, right ventricular hypertrophy, patchy lung infiltrates, a platelet count of 1500 and a clotting time of 60 seconds. A V/Q scan indicated a high probability of pulmonary embolism. Further investigations showed that the patient was positive for lupus anticoagulant and cardiolipin antibodies. A diagnosis of primary antiphospholipid syndrome was made. The patient''s high risk of strokes and hemorrhaging prompted investigation by a 99mTc-HMPAO brain scan. Further V/Q scans were performed to follow up the initial finding of multiple pulmonary embolism and a R-L shunt study was performed to investigate a left subclavian murmur. The patient was admitted for four weeks and began treatment which included cyclaphosphamide, corticosteroids and plasmaphoresis and was discharged when stable. Over the next six months he was re admitted three times for relapse of antiphospholipid syndrome. On his fourth admission he collapsed and died five hours after admission. Cause of death was due to cardiac arrhythmia secondary to severe right ventricular hypertrophy and dilation. The effects of antiphospholipid syndrome was believed to be responsible for this outcome

    Full Text Available This paper investigates key success factors in logistics outsourcing. Amodel is used to illustrate outsourcing relationships and then appliedto three examples from the logistics sector. The model is presented asa tool which can help managers to minimize the chance of failure byexplicitly addressing key issues prior to the implementation of a partnership.In order to fully capture the complexity of the outsourcingprocess, the model is refined by the analysis of implementation of outsourcingmethodology and the analysis of the presence of outsourcingmyths in each case. We find that the implementation of outsourcingmethodology is critical to successful outsourcing. Overall, we find thatthe main common factors leading to logistics outsourcing success, afterthe right third party service provider has been selected, are improvedservice levels and commercial viability for both parties, joint vision andobjectives of the partnership, clear roles, top management commitmentand support, communication and trust. The results of the case analysisshed light on what is the key to a successful outsourcing relationshipand indicate how the architecture of logistics outsourcing can be analyzedand improved.

  10. Towards More Case Study Research in Entrepreneurship

    Directory of Open Access Journals (Sweden)

    Tom Duxbury

    2012-03-01

    Full Text Available Entrepreneurship as an emerging discipline has made good strides, but according to some, has fallen short of bringing its theory and literature up to the standards of others in the management sciences. Rich with the descriptive detail needed for insightful theory building in entrepreneurship, scholars have called for more case study research, particularly those incorporating non-retrospective and longitudinal observations. At the same time however, it has become rare to find such research published in A-level journals dedicated to entrepreneurship. A survey presented here of major entrepreneurship journals over the past six years revealed a publication rate of only 3% using the case study method. This presents a major impediment for developing fresh research in this field based upon the study of real cases. The author explores how the case study method has been applied to entrepreneurship research and provides recommendations for improved publication rates.

    This book presents a unique approach for studying mechanisms and machines with drawings that were depicted unclearly in ancient Chinese books. The historical, cultural and technical backgrounds of the mechanisms are explained, and various mechanisms described and illustrated in ancient books are introduced. By utilizing the idea for the conceptual design of modern mechanisms, all feasible designs of ancient mechanisms with uncertain members and joints that meet the technical standards of the subjects’ time periods are synthesized systematically. Ancient Chinese crossbows (the original crossbow and repeating crossbows), textile mechanisms (silk-reeling mechanism, spinning mechanisms, and looms), and many other artisan's tool mechanisms are used as illustrated examples.  Such an approach provides a logical method for the reconstruction designs of ancient mechanisms with uncertain structures. It also provides an innovative direction for researchers to further identify the original structures of mechanisms...

    2016-04-01

    The purpose of the current study was to identify Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) correlates of police officer integrity violations and other problem behaviors in an archival database with original MMPI item responses and collateral information regarding integrity violations obtained for 417 male officers. In Study 1, we estimated MMPI-2-RF scores from the MMPI item pool (which includes approximately 80% of the MMPI-2-RF items) in a normative sample, a psychiatric inpatient sample, and a police officer sample, and conducted analyses that demonstrated the comparability of estimated and full scale scores for 41 of the 51 MMPI-2-RF scales. In Study 2, we correlated estimated MMPI-2-RF scores with information about subsequent integrity violations and problem behaviors from the integrity violation data set. Several meaningful associations were obtained, predominately with scales from the emotional, thought, and behavioral dysfunction domains of the MMPI-2-RF. Application of a correction for range restriction yielded substantially improved validity estimates. Finally, we calculated relative risk ratios for the statistically significant findings using cutoffs lower than 65T, which is traditionally used to identify clinically significant elevations, and found several meaningful relative risk ratios.

  11. Mining Product Data Models: A Case Study

    Directory of Open Access Journals (Sweden)

    Cristina-Claudia DOLEAN

    2014-01-01

    Full Text Available This paper presents two case studies used to prove the validity of some data-flow mining algorithms. We proposed the data-flow mining algorithms because most part of mining algorithms focuses on the control-flow perspective. First case study uses event logs generated by an ERP system (Navision after we set several trackers on the data elements needed in the process analyzed; while the second case study uses the event logs generated by YAWL system. We offered a general solution of data-flow model extraction from different data sources. In order to apply the data-flow mining algorithms the event logs must comply a certain format (using InputOutput extension. But to respect this format, a set of conversion tools is needed. We depicted the conversion tools used and how we got the data-flow models. Moreover, the data-flow model is compared to the control-flow model.

    2012-01-01

    As a continuation from summer 2012, the Shuttle Case Study Collection has been developed using lessons learned documented by NASA engineers, analysts, and contractors. Decades of information related to processing and launching the Space Shuttle is gathered into a single database to provide educators with an alternative means to teach real-world engineering processes. The goal is to provide additional engineering materials that enhance critical thinking, decision making, and problem solving skills. During this second phase of the project, the Shuttle Case Study Collection website was developed. Extensive HTML coding to link downloadable documents, videos, and images was required, as was training to learn NASA's Content Management System (CMS) for website design. As the final stage of the collection development, the website is designed to allow for distribution of information to the public as well as for case study report submissions from other educators online.

  14. Commercializing Government-sponsored Innovations: Twelve Successful Buildings Case Studies

    Science.gov (United States)

    Brown, M. A.; Berry, L. G.; Goel, R. K.

    1989-01-01

    This report examines the commercialization and use of R and D results funded by DOE's Office of Buildings and Community Systems (OBCS), an office that is dedicated to improving the energy efficiency of the nation's buildings. Three goals guided the research described in this report: to improve understanding of the factors that hinder or facilitate the transfer of OBCS R and D results, to determine which technology transfer strategies are most effective and under what circumstances each is appropriate, and to document the market penetration and energy savings achieved by successfully-commercialized innovations that have received OBCS support. Twelve successfully-commercialized innovations are discussed here. The methodology employed involved a review of the literature, interviews with innovation program managers and industry personnel, and data collection from secondary sources. Six generic technology transfer strategies are also described. Of these, contracting R and D to industrial partners is found to be the most commonly used strategy in our case studies. The market penetration achieved to date by the innovations studied ranges from less than 1% to 100%. For the three innovations with the highest predicted levels of energy savings (i.e., the flame retention head oil burner, low-E windows, and solid-state ballasts), combined cumulative savings by the year 2000 are likely to approach 2 quads. To date the energy savings for these three innovations have been about 0.2 quads. Our case studies illustrate the important role federal agencies can play in commercializing new technologies.

  2. Verification of multi-proxy paleoclimatic studies: a case study

    Science.gov (United States)

    McIntyre, S.; McKitrick, R.

    2004-12-01

    ,000 sets of 70 red noise series modeled through fractional difference models to have the same red noise persistence as the critical North American AD1400 tree ring network. These calculations regularly resulted in "hockey-stick" shaped PC1s with sharp inflections at the start of the 20th century. We then modeled the resulting 10,000 PC1s against NH temperature and found that the 99 percent RE significance level was 0.59. By this benchmark, the reported RE statistic (0.51) in MBH98 for the AD1400 step lacks statistical significance. Most dendroclimatic reconstructions also provide statistics other than an RE statistic, including R2 and Coefficient of Efficiency, but MBH98 does not and the authors have refused to provide supporting data from which the statistics can be calculated. In our emulations of their calculations, we have been unable to replicate anything close to the reported RE results other than through re-tuning, a procedure not described in MBH98. With a re-tuning step, for the critical AD1400 step, we have obtained an RE of 0.46, but with an R2 of only 0.02 and a CE of minus 0.26, all of which lack statistical significance. This case study illustrates for extreme caution in basing public policy on articles, such as MBH98, whose claims cannot be verified.

    Siebein, Gary; Lilkendey, Robert; Skorski, Stephen

    2005-04-01

    Case studies of 3 green buildings with LEED certifications that required extensive acoustical retrofit work to become satisfactory work environments for their intended user groups will be used to define areas where green building design concepts and acoustical design concepts require reconciliation. Case study 1 is an office and conference center for a city environmental education agency. Large open spaces intended to collect daylight through clerestory windows provided large, reverberant volumes with few acoustic finishes that rendered them unsuitable as open office space and a conference room/auditorium. Case Study 2 describes one of the first gold LEED buildings in the southeast whose primary design concepts were so narrowly focused on thermal and lighting issues that they often worked directly against basic acoustical requirements resulting in sound levels of NC 50-55 in classrooms and faculty offices, crosstalk between classrooms and poor room acoustics. Case study 3 is an environmental education and conference center with open public areas, very high ceilings, and all reflective surfaces made from wood and other environmentally friendly materials that result in excessive loudness when the building is used by the numbers of people which it was intended to serve.

  2. Hydropower recovery in water supply systems: Models and case study

    International Nuclear Information System (INIS)

    Highlights: • We present hydropower recovery models for water supply systems. • Hydropower recovery potential in water supply systems is highly variable. • The case studied could make the supply systems self-sufficient in terms of energy. • Hydropower recovery can reduce GHGs emissions and generate carbon credits. - Abstract: The energy efficiency of water supply systems can be increased through the recovery of hydraulic energy implicit to the volumes of water transported in various stages of the supply process, which can be converted into electricity through hydroelectric recovery systems. Such a process allows the use of a clean energy source that is usually neglected in water supplies, reducing its dependence on energy from the local network and the system’s operation costs. This article evaluates the possibilities and benefits of the use of water supply facilities, structures and equipment for hydraulic energy recovery, addressing several applicable hydroelectric models. A real case study was developed in Brazil to illustrate the technical, economic and environmental aspects of hydropower recovery in water supply systems

  3. Revaluating the Place of Cycloid Psychoses: Case Study

    Directory of Open Access Journals (Sweden)

    Bruno Gonçalves Teixeira

    2016-07-01

    Full Text Available Introduction: Karl Kleist primarily described the concept of cycloid psychosis. Leonhard set the basis for the current conceptualization of the disorder describing three overlapping subtypes and Perris developed the first operational diagnostic criteria. The diagnosis of cycloid psychosis has a long tradition in European psychiatry, but the cycloid concept is not explicitly included in standard international diagnostic schemes (DSM 5 and ICD-10 leading to a controversial debate about its utility and validity. Aims: This article intends to evaluate, from a case study, the cycloid psychosis concept highlighting its importance and its clinical and predictive validity. Methods: The authors present a case study of recurrent psychosis with total inter-episode remission and minimal functional impairment. Results and Discussion: The article illustrates the importance of the diagnosis of cycloid psychosis given its distinct prognosis and treatment response compared with other psychoses. Conclusion: While this disorder, of unknown incidence, is not well reported, it is worthy of further investigation and clinical attention given its generally favorable prognosis and potentially distinct pathophysiology and treatment.

  11. Chloride Channel Myotonia: Study of Five Cases

    Directory of Open Access Journals (Sweden)

    M Ghofrani

    2002-09-01

    Full Text Available Chloride channel Myotonia is a form of channelopathy, and Myotonia is its manifestation. Myotonia may be defined as delayed relaxation of skeletal muscle after its contraction. Decreased chloride conductance across the transverse tubular system, renders the muscle membrane hyper-excitable and leads to repetitive firing, creating Myotonia. Myotonia congenital is another name for chloride channel Myotonia. Myotonia congenital appears in autosomal dominant type called Thomson disease, autosomal recessive type called Becker disease, and a type with sporadic occurrence. Symptoms appear in the first or second decade of life. Repeated muscle contraction, the so called warm up, result in resolution of the Myotonia stiffness. Muscle stiffness and hypertrophy is another finding at physical examination. In this study we report on 5 patients, which had clinical and electrical signs of Myotonia. Muscle hypertrophy and warm up phenomena were present in all cases. CPK measurement of all cases were normal. 2 patients underwent muscle biopsy that showed only atrophy and increased central nuclei. In three cases autosomal recessive inheritance (Becker, in one case autosomal dominant inheritance (Thomsen and in one case sporadic occurrence was suggested. With respect to successful results of carbamazepine therapy in 4 patients, and being excellent in one of them, we suggest carbamazepine for the first choice of Myotonia treatment.

  14. Using simulation to develop testable functionalist explanations: a case study of church survival.

    Science.gov (United States)

    Chattoe, Edmund

    2006-09-01

    Many arguments for and against functionalism have revolved around logical and methodological issues, discouraging attempts to develop testable functionalist theories. This paper takes a different approach, arguing that the problem with sociological functionalism is not its logic of explanation but the absence of appropriate techniques for formalizing functionalist theories. The solution presented --agent-based simulation --is illustrated by a case study: a functionalist account of church survival. The case study suggests that there is nothing wrong with the logic of functionalism properly formalized, illustrates how simulation can enable testing of functionalist explanations and suggests why existing sociological methods have not proved fruitful for this task. In the light of new techniques like simulation, the current neglect of functionalism may no longer be justified. PMID:16939592

    2007-11-01

    Full Text Available Abstract Background Publicly funded clinical trials require a substantial commitment of time and money. To ensure that sufficient numbers of patients are recruited it is essential that they address important questions in a rigorous manner and are managed well, adopting effective marketing strategies. Methods Using methods of analysis drawn from management studies, this paper presents a structured assessment framework or reference model, derived from a case analysis of the MRC's CRASH trial, of 12 factors that may affect the success of the marketing and sales activities associated with clinical trials. Results The case study demonstrates that trials need various categories of people to buy in – hence, to be successful, trialists must embrace marketing strategies to some extent. Conclusion The performance of future clinical trials could be enhanced if trialists routinely considered these factors.

    2008-11-01

    Full Text Available This article is a qualitative case study describing the experience of Angélica an international graduate student from Latin America, who received her doctorate at the University of New Mexico in the United States. Her case demonstrated how administrators and faculty learn about the experience and struggles endured by international students, especially those who learned English a short time before admission to graduate studies. While a single case is understandably idiographic in nature and inevitably requires a larger sample, from the analysis of Angélica’s case and the analysis of the relevant literature common topics emerged persuading me to conclude that the issues that commonly impact the life of international students have to do with: 1 second language problems; 2 the quality of academic advisement received; 3 the availability of financial support; 4 the level of integration into their academic program; and 5 the level of cultural adjustment in their host country.

    A case-study collection was developed for NASA's Space Shuttle Program. Using lessons learned and documented by NASA KSC engineers, analysts, and contractors, decades of information related to processing and launching the Space Shuttle was gathered into a single database. The goal was to provide educators with an alternative means to teach real-world engineering processes and to enhance critical thinking, decision making, and problem solving skills. Suggested formats were created to assist both external educators and internal NASA employees to develop and contribute their own case-study reports to share with other educators and students. Via group project, class discussion, or open-ended research format, students will be introduced to the unique decision making process related to Shuttle missions and development. Teaching notes, images, and related documents will be made accessible to the public for presentation of Space Shuttle reports. Lessons investigated included the engine cutoff (ECO) sensor anomaly which occurred during mission STS-114. Students will be presented with general mission infom1ation as well as an explanation of ECO sensors. The project will conclude with the design of a website that allows for distribution of information to the public as well as case-study report submissions from other educators online.

    2014-12-01

    Full Text Available This paper introduces two novel applications of systemic design to facilitate a comparison of alternative methodologies that integrate systems thinking and design. In the first case study, systemic design helped the Procurement Department at the University of Toronto re-envision how public policy is implemented and how value is created in the broader university purchasing ecosystem. This resulted in an estimated $1.5 million in savings in the first year, and a rise in user retention rates from 40% to 99%. In the second case study, systemic design helped the clean energy and natural resources group within the Government of Alberta to design a more efficient and effective resource management system and shift the way that natural resource departments work together. This resulted in the formation of a standing systemic design team and contributed to the creation of an integrated resource management system. A comparative analysis of the two projects identifies a shared set of core principles for systemic design as well as areas of differentiation that reveal potential for learning across methodologies. Together, these case studies demonstrate the complementarity of systems thinking and design thinking, and show how they may be integrated to guide positive change within complex sociotechnical systems.

    ABSTRACT: This case-study attempts to present a brief glossary of Northern Sotho medical terms. It is a follow-up of a similar case-study (Madiba, Mphahlele and Kganyago 2003, which was an attempt to capture and present Northern Sotho cooking terms. Case-study I consists of the names for utensils, ingredients and the processes involved in the preparation of cultural dishes. With both these case-studies, the intention has been to use the opportunities availing themselves for the pres-ervation and valorisation of Northern Sotho, including the extension of its corpora to support national dictionary-making processes. The case-study methodology has been very useful for the purposes of this project and the context within which it was undertaken. It aims to provide a model for the collection and presentation of authentic Northern Sotho terminology which otherwise would hardly have been accessible.

    2013-04-01

    The teaching of biomaterials as case study by on-line platform , susceptible to develop both individually and in groups, got different objectives proposed by the European Higher Education System, among which include: participate actively in the teaching-learning process by students, interpreting situations, adapt processes and solutions. It also improves oral and written communication, analytical skills and synthesis and also the ability to think critically. Biomaterials have their origin in biominerals. These are solid inorganic compounds of defined structure, consisting of molecular control mechanisms that operate in biological systems. Its main functions are: structural support, a reservoir of essential elements, sensors, mechanical protection and storage of toxic elements. Following the demand of materials compatible with certain functional systems of our body, developed biomaterials. Always meet the condition of biocompatibility. Should be tolerated by the body and do not provoke rejection. This involves a comprehensive study of physiological conditions and the anatomy of the body where a biomaterial has to be implemented. The possibility of generating new materials from biominerals has a major impact in medicine and other fields could reach as geology, construction, crystallography, etc. While the study of these issues is in its infancy today, can be viewed as an impact on the art and future technology. Planning case study that students would prepare its report for discussion in subgroups. Occurs then the pooling of individual analysis, joint case discussion and adoption by the subgroup of a consensual solution to the problem. The teacher as facilitator and coordinator of the final case analysis, sharing leads to group-wide class and said the unanimous decision reached by the students and gives his opinion on the resolution of the case.

  9. Commercializing government-sponsored innovations: Twelve successful buildings case studies

    Energy Technology Data Exchange (ETDEWEB)

    Brown, M.A.; Berry, L.G.; Goel, R.K.

    1989-01-01

    This report examines the commercialization and use of R and D results funded by DOE's Office of Buildings and Community Systems (OBCS), an office that is dedicated to improving the energy efficiency of the nation's buildings. Three goals guided the research described in this report: to improve understanding of the factors that hinder or facilitate the transfer of OBCS R and D results, to determine which technology transfer strategies are most effective and under what circumstances each is appropriate, and to document the market penetration and energy savings achieved by successfully-commercialized innovations that have received OBCS support. Twelve successfully-commercialized innovations are discussed here. The methodology employed involved a review of the literature, interviews with innovation program managers and industry personnel, and data collection from secondary sources. Six generic technology transfer strategies are also described. Of these, contracting R and D to industrial partners is found to be the most commonly used strategy in our case studies. The market penetration achieved to date by the innovations studied ranges from less than 1% to 100%. For the three innovations with the highest predicted levels of energy savings (i.e., the flame retention head oil burner, low-E windows, and solid-state ballasts), combined cumulative savings by the year 2000 are likely to approach 2 quads. To date the energy savings for these three innovations have been about 0.2 quads. Our case studies illustrate the important role federal agencies can play in commercializing new technologies. 27 refs., 21 figs., 4 tabs.

  11. New Geographies of Work: A Case Study from Sweden

    Directory of Open Access Journals (Sweden)

    Brita Hermelin

    2012-01-01

    Full Text Available This paper describes and analyses the geography of work, i.e., the spatial patterns in where paid work is done. The geography of work may diverge from the geography of employment when paid work is done at the premises of client organizations, during commuting, on business trips, on external meetings, at home or at other places. The particular patterns in the geography of work depend on a number of factors, possibilities and constraints. The paper takes its point of departure from the debate about how structural economic changes resulting from evolving service industries and the development of Information and Communication Technology (ICT entail new forms for the organization of paid work. Flexibility, reflexivity, flows and places are key concepts. The paper presents a case study from Stockholm that takes a workplace perspective and looks at knowledge-intensive work in a public sector organization. The empirical study analyses data from interviews, time diaries and a questionnaire. We analyse how the geography of work is the result of negotiations between different parties and in different arenas, and how this spatial pattern is the result of the character of work tasks and accessibility of ICT support. The discussion illustrates a complex picture of the coexistence of spatial fix and spatial flexibility, and how this may cause tensions but also convenient solutions for organizing and conducting paid work.

  12. Practising Knowing at Work: a case study in healthcare

    Directory of Open Access Journals (Sweden)

    Manidis, Marie

    2015-12-01

    Full Text Available In healthcare today, medical knowledge is still largely viewed by the health sector as an ‘epistemology of possession’; a perspective which gives primacy to knowledge transfer and communication aspects of care. In my view, this perspective underestimates the complexity of the social, material, situated and collective way that doctors and nurses actually work together – and do knowledge – in order to care for their patients . I illustrate this complexity based on data from a large Australian Research Council (ARC study by closely examining a case study of how a healthcare team cares for a dying 67-year old patient, Joel in an Emergency Room (ER. Drawing on ethnographic and linguistic ethnographic methodologies and data, ‘knowledge’ is proposed, not as ‘possession’, but as an activity, ‘a collective and distributed ‘doing’ situated in time and space, and therefore taking place in [the] work practices [of the ERs nurses and doctors]. Theoretically the paper adopts a ‘practice-based’ analysis of how team knowledge is done in the ER. In adopting this approach the paper challenges conventional views on knowledge, knowledge transfer and communication in healthcare – and more broadly in other organizational contexts – alerting us to new ways of thinking about how team knowledge is done and how organizational learning might be reconceptualized.

  1. Environmental qualification - facilities and case studies

    International Nuclear Information System (INIS)

    The term environmental qualification is used for assurance or guarantee for satisfactory performance of hardware under specified environmental conditions including normal, abnormal and accident conditions. To generate confidence about satisfactory performance in reasonable time, hardware must be tested under accelerated conditions. For testing and measuring performance parameters, it is essential to have adequate facilities and experienced and inquisitive staff so that qualified and reliable hardware can be manufactured by active participation of manufacturers, users and researchers. Top priority is given to the determination of characteristics, capabilities and limitations of hardware before really starting accelerated testing so that maximum information can be extracted before failure of hardware. This paper describes test and measurement facilities set up at the Bhabha Atomic Research Centre for environmental qualification and some case studies where it has been possible to make significant contributions towards reliability assessment, upgrading and indigenisation. Apart from climatic test facilities (thermal and humidity chambers), a Loss Of Coolant Accident (LOCA) environment simulator and synergistic simulator (combined environment test facility comprising temperature, humidity, gamma radiation and electrical stresses for studying interaction effects) have been set up. Notable case studies are :(1) Assessment of residual life-spans of cables and elastomeric components, (2) Reliability upgradation of indicating alarm meters and solenoid valves, (3) Assessment of survival capability of process instruments under LOCA environment, (4)Assessment of reusability of relays exposed to smoke and water spray in fire incident in a nuclear power station.

    Reinforcement Learning algorithms offer interesting features for the control of autonomous systems, such as the ability to learn from direct interaction with the environment, and the use of a simple reward signalas opposed to the input-outputs pairsused in classic supervised learning. The reward signal indicates the success of failure of the actions executed by the agent in the environment. In this work, are described RL algorithmsapplied to two case studies: the Crawler robot and the widely known inverted pendulum. We explore RL capabilities to autonomously learn a basic locomotion pattern in the Crawler, andapproach the balancing problem of biped locomotion using the inverted pendulum.

    2013-12-01

    This presentation addresses the question: must socio-economic benefits of geospatial projects be considered intangible and thus unquantifiable? The question will be answered from the perspective of an engineer and geospatial practitioner, with examples provided from case studies using micro level financial analysis. Topics will include: 1. Quantification as a tool for setting and achieving goals, illustrated with individual and societal uses of measurement. 2. Geospatial data as a driver for economic and social development. 3. Building use cases from documented work processes, demographic information and external research results. 4. Moving beyond GDP to quantify the well being of individuals and society. 5. Extrapolation of case study results to quantify a technology's current and potential return on investment to society. 6. Is it realistic for society to work toward commonly held measurements of well being? Or should individual cases maintain uniquely developed measurements to more accurately characterize their results?

  13. From Science to e-Science to Semantic e-Science: A Heliosphysics Case Study

    Science.gov (United States)

    Narock, Thomas; Fox, Peter

    2011-01-01

    The past few years have witnessed unparalleled efforts to make scientific data web accessible. The Semantic Web has proven invaluable in this effort; however, much of the literature is devoted to system design, ontology creation, and trials and tribulations of current technologies. In order to fully develop the nascent field of Semantic e-Science we must also evaluate systems in real-world settings. We describe a case study within the field of Heliophysics and provide a comparison of the evolutionary stages of data discovery, from manual to semantically enable. We describe the socio-technical implications of moving toward automated and intelligent data discovery. In doing so, we highlight how this process enhances what is currently being done manually in various scientific disciplines. Our case study illustrates that Semantic e-Science is more than just semantic search. The integration of search with web services, relational databases, and other cyberinfrastructure is a central tenet of our case study and one that we believe has applicability as a generalized research area within Semantic e-Science. This case study illustrates a specific example of the benefits, and limitations, of semantically replicating data discovery. We show examples of significant reductions in time and effort enable by Semantic e-Science; yet, we argue that a "complete" solution requires integrating semantic search with other research areas such as data provenance and web services.

    Full Text Available Emergency management agencies are progressively using social media for the sourcing and distribution of disaster information. Emergency management agencies are often unsure as to how to best identify and assess social media concerns (e.g. information security, trust which must be addressed to develop a social media-enabled disaster information management environment. This paper adopts the Social Architecture Viewpoint Assessment (SAVA framework for identifying and assessing social media concerns from four different viewpoints: IT, Value, Resource and Management. This paper demonstrates the use of the SAVA framework in the context of an in-depth empirical case study of an Australian emergency management agency. The results of this study indicate that the SAVA framework is useful for emergency information management managers in identifying and assessing social media concerns.

  15. Commercializing Emerging Renewable Energy: A Case Study

    Directory of Open Access Journals (Sweden)

    Matti Lehtovaara

    2012-12-01

    Full Text Available A broad scientific consensus exists that the global climate is changing. The Earth’s surface temperature could rise significantly over the next few decades, leading to us witnessing an entirely new and unknown planet. Improved energy efficiency, decreasing use of fossil fuels and wide diffusion of various renewable energy sources are among the focal measures to limit global warming to a sustainable level. The objective of this study is to analyse how renewable energy, such as wind power and bioenergy, could be efficiently commercialized. The evaluation is based on a case study and expert analyses exploiting lateral and parallel thinking methods, and group decision support systems tools. The results reveal that some of the generated ideas are ready for implementation to commercialize renewable energy, whereas others still require technical and commercial development and improvements before maturity.

  16. Experimental quantum annealing: case study involving the graph isomorphism problem

    Science.gov (United States)

    Zick, Kenneth M.; Shehab, Omar; French, Matthew

    2015-06-01

    Quantum annealing is a proposed combinatorial optimization technique meant to exploit quantum mechanical effects such as tunneling and entanglement. Real-world quantum annealing-based solvers require a combination of annealing and classical pre- and post-processing; at this early stage, little is known about how to partition and optimize the processing. This article presents an experimental case study of quantum annealing and some of the factors involved in real-world solvers, using a 504-qubit D-Wave Two machine and the graph isomorphism problem. To illustrate the role of classical pre-processing, a compact Hamiltonian is presented that enables a reduced Ising model for each problem instance. On random N-vertex graphs, the median number of variables is reduced from N2 to fewer than N log2 N and solvable graph sizes increase from N = 5 to N = 13. Additionally, error correction via classical post-processing majority voting is evaluated. While the solution times are not competitive with classical approaches to graph isomorphism, the enhanced solver ultimately classified correctly every problem that was mapped to the processor and demonstrated clear advantages over the baseline approach. The results shed some light on the nature of real-world quantum annealing and the associated hybrid classical-quantum solvers.

  17. Designing climate-smart conservation: guidance and case studies.

    Hansen, Lara; Hoffman, Jennifer; Drews, Carlos; Mielbrecht, Eric

    2010-02-01

    To be successful, conservation practitioners and resource managers must fully integrate the effects of climate change into all planning projects. Some conservation practitioners are beginning to develop, test, and implement new approaches that are designed to deal with climate change. We devised four basic tenets that are essential in climate-change adaptation for conservation: protect adequate and appropriate space, reduce nonclimate stresses, use adaptive management to implement and test climate-change adaptation strategies, and work to reduce the rate and extent of climate change to reduce overall risk. To illustrate how this approach applies in the real world, we explored case studies of coral reefs in the Florida Keys; mangrove forests in Fiji, Tanzania, and Cameroon; sea-level rise and sea turtles in the Caribbean; tigers in the Sundarbans of India; and national planning in Madagascar. Through implementation of these tenets conservation efforts in each of these regions can be made more robust in the face of climate change. Although these approaches require reconsidering some traditional approaches to conservation, this new paradigm is technologically, economically, and intellectually feasible. PMID:20121842

  19. Case studies in control putting theory to work

    CERN Document Server

    Juričić, Đani

    2013-01-01

    Case Studies in Control presents a framework to facilitate the use of advanced control concepts in real systems based on two decades of research and over 150 successful applications for industrial end-users from various backgrounds. In successive parts the text approaches the problem of putting the theory to work from both ends, theoretical and practical. The first part begins with a stress on solid control theory and the shaping of that theory to solve particular instances of practical problems. It emphasizes the need to establish by experiment whether a model-derived solution will perform properly in reality. The second part focuses on real industrial applications based on the needs and requirements of end-users. Here, the engineering approach is dominant but with theoretical input of varying degree depending on the particular process involved. Following the illustrations of the progress that can be made from either extreme of the well-known theory–practice divide, the text proceeds to a third part relate...

    While the study of the origins of biological diversity across species has provided numerous examples of adaptive divergence, the realization that it can occur at microgeographic scales despite gene flow is recent, and scarcely illustrated. We review here evidence suggesting that the striking phenotypic differentiation in ecologically relevant traits exhibited by blue tits Cyanistes caeruleus in their southern range-edge putatively reflects adaptation to the heterogeneity of the Mediterranean habitats. We first summarize the phenotypic divergence for a series of life history, morphological, behavioural, acoustic and colour ornament traits in blue tit populations of evergreen and deciduous forests. For each divergent trait, we review the evidence obtained from common garden experiments regarding a possible genetic origin of the observed phenotypic differentiation as well as evidence for heterogeneous selection. Second, we argue that most phenotypically differentiated traits display heritable variation, a fundamental requirement for evolution to occur. Third, we discuss nonrandom dispersal, selective barriers and assortative mating as processes that could reinforce local adaptation. Finally, we show how population genomics supports isolation - by - environment across landscapes. Overall, the combination of approaches converges to the conclusion that the strong phenotypic differentiation observed in Mediterranean blue tits is a fascinating case of local adaptation.

    In Chap.2, we presented the definition of resilience based on viability theory (Martin 2004), and we argued that this definition is more general than the equilibrium based definition, and fits better the usual meaning of resilience. Several chapters illustrate this approach on individual based models (language dynamics, bacteria, savanna). In each of these case studies, a preliminary work is to approximate the individual based model with more of a synthetic model, because the tools for comput...

    Full Text Available Os trigonum syndrome is one of the rare causes of posterior foot pain. Ostrigonum, which is placed at the posterior of talus, is an accessory bone. Ostrigonum syndrome causes back foot pain due to compression between talusand calcaneus. In this study, we present a case of os trigonum syndrome ,which is a rare disease and is generally missed. A 65-year-old female patientwith a complaint of left foot pain for the last 2 months persented to our outpatientclinic. In the physical examination, plantar flexion of the ankle andtoe was painful. Patient’s pain was evaluated by the visual analog scale andnoted as 8 cm. There was sensitivity at the posterior of talus during palpation.Os trigonum syndrome was diagnosed based on radiological examinationsand a physical therapy program consisting of transcutaneous electrical nervestimulation (TENS, cold pack, foot and ankle range of motion and strengtheningexercises was started. After the treatment, pain VAS decreased to 2cm,and then the patient was followed clinically. As in our case, os trigonum syndromeshould also be taken into consideration in patients complaining withposterior foot pain apart from other frequently encountered causes. In suchcases, physical therapy programs are very effective in pain management andin reducing the cost of treatment. Turk J Phys Med Rehab 2013;59:161-4.

    Measured energy performance data are essential to national efforts to improve building efficiency, as evidenced in recent benchmarking mandates, and in a growing body of work that indicates the value of permanent monitoring and energy information feedback. This paper presents case studies of energy information systems (EIS) at four enterprises and university campuses, focusing on the attained energy savings, and successes and challenges in technology use and integration. EIS are broadly defined as performance monitoring software, data acquisition hardware, and communication systems to store, analyze and display building energy information. Case investigations showed that the most common energy savings and instances of waste concerned scheduling errors, measurement and verification, and inefficient operations. Data quality is critical to effective EIS use, and is most challenging at the subsystem or component level, and with non-electric energy sources. Sophisticated prediction algorithms may not be well understood but can be applied quite effectively, and sites with custom benchmark models or metrics are more likely to perform analyses external to the EIS. Finally, resources and staffing were identified as a universal challenge, indicating a need to identify additional models of EIS use that extend beyond exclusive in-house use, to analysis services.

    Magnetic resonance imaging (MRI) is degraded by metal-implant-induced artifacts when used for the diagnostic assessment of vertebral compression fractures in patients with instrumented spinal fusion. Dual-energy computed tomography (DECT) offers a promising supplementary imaging tool in these patients. This case report describes an 85-year-old woman who presented with a suspected acute vertebral fracture after long posterior lumbar interbody fusion. This is the first report of a vertebral fracture that showed bone marrow edema on DECT; however, edema was missed by an MRI STIR sequence owing to metal artifacts. Bone marrow assessment using DECT is less susceptible to metal artifacts than MRI, resulting in improved visualization of vertebral edema in the vicinity of fused vertebral bodies. PMID:27270922

    Fixture is an important manufacturing activity. A fixture design system based on case-based reasoning (CBR) is proposed in this paper. A new method of case representation on the basis of fixture function is presented, where the case representation is constituted of workpiece knowledge, processing feature knowledge, and fixture feature knowledge. Running the prototype system shows that the knowledge representation method, using cases, is a better way to transform and explain the design knowledge.

    Full Text Available This study highlighted the importance of determining the impact that an ineffective mode of transport has on a firm’s transportation model and costs. The main focus of this study was to determine the logistics opportunity costs of using road transport within a mining firm. A case study approach was followed, as the investigation aimed to analyse a complex problem experienced by one company and present it in an easily understandable format. From the results of this study, it was apparent that the logistics opportunity costs associated with the mode of transport was substantial. This highlighted the need for firms to revise their choice of transport mode on a regular basis, as it has a major impact not only on their transportation costs, but also on their inventory holding and carbon emissions. The results also have implications for South Africa’s only freight railway, Transnet Freight Rail, which should not only focus on expanding its existing capacity, but also on improving its customer service delivery whilst containing tariff increases.

    In anticipation of the growing need for adequate mental health care for older adults in residential aged care facilities, psychologists are challenged to overcome several barriers that impede the uptake and delivery of their services in such settings. Information and communication technologies (ICT) have strong potential to overcome some of these barriers by supporting the delivery of evidence-based psychosocial treatments for common psychogeriatric issues. This paper presents two case studies that illustrate when and how psychologists can use various ICT applications (e.g., tablet devices, web-based applications) integrated with cognitive behavioural and reminiscence-based therapies. Both case studies demonstrate that ICT can effectively support the therapeutic alliance, enhance therapeutic engagement, and individualize treatment delivery to accommodate the needs of elderly patients. It is hoped that these case studies will encourage clinicians to consider using ICT to augment therapy with their elderly patients. PMID:27073103

The effects of recreational physical activity and a health-habit orientation program using an illustrated diary on the cardiovascular risk profile of overweight and obese children was investigated. Methods: The weight and height of 314 schoolchildren aged between 9 and 11 years old, in a public school in Brasilia, Federal District, Brazil, were recorded. According to the body mass index (BMI classification proposed by the World Health Organization, 84 were overweight or obese for their age and sex. Of these children, 34 (40% participated in the study. Students were divided into two groups matched for sex, age, BMI, percent body fat (%BF: the intervention group (IG, n = 17 and the control group (CG, n = 17. The IG underwent a program of 10 weeks of exercise with recreational activities and health-habit orientation using an illustrated diary of habits, while no such interventions were used with the CG during the study period. Before and after the intervention, the children's weight, height, BMI, %BF, waist circumference (WC, maximum oxygen intake (VO2max, total cholesterol (TC, high density lipoprotein (HDL, low density lipoprotein (LDL, triglycerides, glucose, eating habits, and physical activity level (PAL were assessed.

    2014-01-01

    This paper focuses on three seemingly unrelated error patterns in the sound system of a child with a phonological delay, Child 218 (male, age 4 years 6 months) and ascribes those error patterns to a larger conspiracy to eliminate fricatives from the phonetic inventory. Employing Optimality Theory for its advantages in characterizing conspiracies, our analysis offers a unified account of the observed repairs. The contextual restrictions on those repairs are, moreover, attributed to early developmental prominence effects, which are independently manifested in another error pattern involving rhotic consonants. Comparisons are made with a published case study involving a different implementation of the same conspiracy, the intent being to disambiguate the force behind certain error patterns. The clinical implications of the account are also considered. PMID:25000372

The present study is a case report. Outcome variables included behavioral, swallowing and quality of life variables, and were assessed at baseline and at the end of the four-week program. Selective variables were also assessed at a follow-up family interview four weeks post program completion. Over the four-week intervention period, the patient demonstrated substantial improvements in: oral acceptance of eating-related objects and a variety of foods (behavioral variable), timing of voluntary saliva swallows and aerophagia levels (swallowing variables) and quality of life. Follow-up interview analysis showed that most skills were retained or improved one-month post intervention. This intensive telepractice program proved to be feasible and effective for this pediatric patient with dysphagia. PMID:25945217

    Full Text Available Support from top management and others is agreed to be an important factor in information systems success and failure, but little is written about how it has its effect and how it might be managed to a project's advantage. A recently developed conceptual framework is described. It covers the nature and forms of support, the way support affects project outcomes, the bases on which support is provided, and the strategies by which support may be managed. The framework is used to analyse a case study in several stages. At the end of the analysis of each stage, the framework's utility is assessed in terms of its explanatory value and the practical advice it suggests. Areas for further research are identified.

    The current study investigated original case descriptions of psychopathy (Cleckley, 1941) in relation to current conceptualizations and general personality traits. Attorneys, forensic psychologists and clinical faculty members completed ratings of psychopathy and personality after reading vignettes based on Cleckley's descriptions of a psychopath. The results suggest that professionals' ratings are consistent with current conceptualizations of psychopathy. Furthermore, the five-factor model (FFM) personality traits of the vignettes aligned with the current literature on the FFM and psychopathy (i.e. low neuroticism, conscientiousness and agreeableness). The results further supported that a general trait model, like the FFM, may be well suited to describe the underlying personality traits of psychopathy. Gender differences were also examined.

    Full Text Available In todays economics, the fact that information is a major factor of production and of increasing importance as a source of competitive advantage is a generally accepted truism. The trend towards global markets has strongly impacted the competitive situation of many enterprises. Never has the economic environment been subject to so many drastic and rapid changes. This put new weight factors on the requirements for design of business process. This paper explores the case of an Italian legal office that has studied more and more innovative solutions both to satisfy the demands of the clienteles and to oppose the action of the new competitors. Comparing classic models and the theories of Porter with the characteristics and needs of new economy, it shows as the ability to possess, to easily have access, to creatively use of information constitutes one of the more strategic sources of the competitive advantage.

    Rates of survival after cardiac arrest are low and correlate with the quality of cardiopulmonary resuscitation (CPR). Devices that deliver automated CPR (A-CPR) can provide sustained and effective chest compressions, which are especially useful during patient transfer and while simultaneous invasive procedures are being performed. The use of such devices can also release members of resuscitation teams for other work. This article presents a case study involving a man with acute myocardial infarction complicated by cardiogenic shock and pulmonary oedema. It describes how ED nursing and medical teams worked together to deliver A-CPR, discusses the use of A-CPR devices in a tertiary cardiac centre, and highlights the advantages of using such devices.

    "Robust Control Systems" gives a self-contained introduction to modern Control Theory. It thus adds a textbook to the existing research-oriented literature on Robust Control. The author lays emphasis on the modern aspects of the design of controllers with prescribed performance and robustness properties. Different to the classical engineering approach, a rigorous mathematical treatment is essential for the full understanding and applicability of the modern methods such as H2 or H8 control or methods based on the structured singular value µ. Nevertheless, no prior knowledge of Control Theory is required as the classical fundamentals are introduced within the first few chapters. Subsequently a large part of the text provides elementary examples and industrial case studies, which are developed in full detail to show how modern methods can be applied to advanced problems. They make intensive use of MATLAB, especially the Control Systems Toolbox and the µ-Analysis and Synthesis Toolbox.

    International Nuclear Information System (INIS)

    A systems perspective on safety management is introduced followed by two briefly presented case studies of safety management in non-nuclear contexts. The first study concerns a car manufacturer and the second study a road traffic tunnel system. The risks of a car accident in the first case study are evident. The great exposure generates many incidents and accidents. In the second study, the rather low traffic intensity through the tunnel produces few incidents and accidents and only a few fatal accidents over the years. Yet, the risk of the individual traveler is much greater in the tunnel than on the average road. The case studies are presented in a systems perspective with emphasis on information feedback about the risks of the systems. The first case study illustrates high quality safety management, while the second case study shows many weaknesses of the safety management in the tunnel system. Some differences in safety management between the case studies are noted. The last part of the study presents an organizational perspective on safety management and offers alternative theoretical perspectives on the concept of safety management. The report shows that further studies are needed both (1) to develop a frame of reference for describing safety management across industries and activities and (2) to collect data illustrating of good and poor safety management. Then, the results can be used to strengthen and/or improving safety management in the nuclear power industry and its regulators

  8. Landslide Economics: Concepts and Case Studies

    Science.gov (United States)

    Klose, Martin; Damm, Bodo

    2015-04-01

    Landslide economics is vital for fundamental understanding of landslide risk as dealing with two important topics: (i) impact assessment, either as damage statistics or cost modeling, and (ii) vulnerability assessment, i.e., the study of exposure, sensitivity, and resilience to landslide damage, ideally from both sociotechnical and financial perspective (e.g., Crovelli and Coe, 2009; Wills et al., 2014). Many aspects addressed in landslide economics have direct influence on landslide risk, including: (i) human activity is often a major causative factor of landslides, not only by predisposing or triggering them, but also as a result of inadequate (low-cost) landslide mitigation; (ii) the level of tolerable or acceptable risk, a measure driving a large part of landslide costs in industrialized countries, is highly variable, differing between individuals, public or private organizations, and societies, with its nature being to change over time; and (iii) decision makers are faced with finding the right balance in landslide mitigation, thus need to weight diverse geological and socioeconomic factors that control its effectiveness in both technical and financial terms (e.g., Klose et al., 2014a). A large part of the complexity in assessing landslide risk as measured by economic costs is due to unique problems in understanding of (i) what types of landslide damage affect human activity and infrastructure in which way, (ii) how society contributes and responds to various kinds of damage, and (iii) how landslide damage is valued in monetary terms. Landslide economics shows the potential to take account of these sociocultural factors to the benefit of risk analysis (e.g., Klose et al., 2014b). The present contribution introduces local and regional case studies in which different economic issues of landslide risk are highlighted using the example of public infrastructures in NW Germany. A special focus is on the following topics: (i) risk culture and created risk, (ii

    Full Text Available Abstract Background It has been established that careful diabetes self-management is essential in avoiding chronic complications that compromise health. Disciplined diet control and regular exercise are the keys for the type 2 diabetes self-management. An ability to maintain one's blood glucose at a relatively flat level, not fluctuating wildly with meals and hypoglycemic medical intervention, would be the goal for self-management. Hemoglobin A1c (HbA1c or simply A1c is a measure of a long-term blood plasma glucose average, a reliable index to reflect one's diabetic condition. A simple regimen that could reduce the elevated A1c levels without altering much of type 2 diabetic patients' daily routine denotes a successful self-management strategy. Methods A relatively simple model that relates the food impact on blood glucose excursions for type 2 diabetes was studied. Meal is treated as a bolus injection of glucose. Medical intervention of hypoglycaemic drug or injection, if any, is lumped with secreted insulin as a damping factor. Lunch was used for test meals. The recovery period of a blood glucose excursion returning to the pre-prandial level, the maximal reach, and the area under the excursion curve were used to characterize one's ability to regulate glucose metabolism. A case study is presented here to illustrate the possibility of devising an individual-based self-management regimen. Results Results of the lunch study for a type 2 diabetic subject indicate that the recovery time of the post-prandial blood glucose level can be adjusted to 4 hours, which is comparable to the typical time interval for non-diabetics: 3 to 4 hours. A moderate lifestyle adjustment of light supper coupled with morning swimming of 20 laps in a 25 m pool for 40 minutes enabled the subject to reduce his A1c level from 6.7 to 6.0 in six months and to maintain this level for the subsequent six months. Conclusions The preliminary result of this case study is encouraging

    Antineutrinos have been proposed as a means of reactor safeguards for more than 30 years and there has been impressive experimental progress in neutrino detection. In this paper we conduct, for the first time, a case study of the application of antineutrino safeguards to a real-world scenario - the North Korean nuclear crisis in 1994. We derive detection limits to a partial or full core discharge in 1989 based on actual IAEA safeguards access and find that two independent methods would have yielded positive evidence for a second core with very high confidence. To generalize our results, we provide detailed estimates for the sensitivity to the plutonium content of various types of reactors, including most types of plutonium production reactors, based on detailed reactor simulations. A key finding of this study is that a wide class of reactors with a thermal power of less than 0.1-1 GWth can be safeguarded achieving IAEA goals for quantitative sensitivity and timeliness with detectors right outside the reactor ...

    The purpose of the present study was to retrospectively evaluate the clinical findings and treatment results for impacted permanent teeth associated with odontomas. We retrospectively investigated 73 odontomas in 72 patients who visited Kyungpook National University Dental Hospital from April 2004 through November 2011. The study was performed using medical records, panoramic radiographs, and pathological reports. Data gathered included age, gender, location, chief complaints, effects on dentition, and treatment of odontoma and the impacted tooth associated with odontoma. Most compound odontomas (46.7%) were found in the second decade and complex odontomas were not related to age. Odontomas showed no gender predilection. Fifty-five cases (75.3%) of odontomas were detected on routine dental radiographs. Sixty percent of compound odontomas occurred in the canine area and 57.1% of complex odontomas in the molar areas. Impaction of permanent teeth (61.6%) was the most common complication on the adjacent teeth. Most odontomas (84.9%) were removed surgically and impacted permanent teeth were managed by surgical removal (53.2%), orthodontic treatment (25.5%), or surgical repositioning (6.4%). There was a statistically significant relation between age and preservation of the impacted permanent teeth associated with odontomas (p<0.01). Early detection and treatment of odontomas increase the possibility of preservation of the impacted tooth. Therefore, it would be suggested that periodic panoramic examination during the first and second decade of life might be beneficial for the early detection and better prognosis of odontomas.

    Although astronomy plays an important role in the most various outreach initiatives, as well as school science curricula, due to its strong visual component in knowledge acquisition, astronomy subjects are not entirely well addressed and accessed by visually impaired students and/or general public. This stresses the need of more tactile material production, still very scarce in an educational context whether formal or informal. This is a case study activity developed based on different schematic tactile images of several objects present in our solar system. These images in relief, highlight, through touch, several relevant features present in the different astronomical objects studied. The scientific knowledge is apprehended through the use of a tactile key, complemented with additional information. Through proper hands-on activities implementation and careful analysis of the outcome, the adapted images associated with an explanatory key prove to be a valuable resource in tactile astronomy domain. Here we describe the process of implementing such initiative near visually impaired students. The struggles and challenges perceived by all involved and the enrichment experience of engaging astronomy with visually impaired audiences, broadening horizons in an overall experience accessible to all.

    Full Text Available Eating disorders lead to special biological and psychological states. The result of the total lack of food is treated in a distinct way by anorexia. Nutritionists have thus had difficulty in coming to an agreement on the best therapy to prevent such disorders. First it is essential to understand which treatment aims are and then to attempt to know how the several treatment models used nowadays can reach those aims. Someone who suffers from eating disorders, together with an inner deformation, suffers from too much sensitiveness. In order to solve these problems, one needs a change in the relationship with oneself, with the others and with the world. This study presents a teenager’s case study – Anorexia. Is, in fact, a problem that society faces and can’t ignore. Many youngsters have already died and others are following their steps. But there are also those ones that succeeded in overcoming the problem and now are reporting their stories.

  19. Non-linearity dynamics in ecosystem response to climate change: Case studies and policy implications

    Many biological, hydrological, and geological processes are interactively linked in ecosystems. These ecological phenomena normally vary within bounded ranges, but rapid, nonlinear changes to markedly different conditions can be triggered by even small differences if threshold values are exceeded. Intrinsic and extrinsic ecological thresholds can lead to effects that cascade among systems, precluding accurate modeling and prediction of system response to climate change. Ten case studies from North America illustrate how changes in climate cna lead to rapid, threshold-type responses within ecological communities; the case studies also highlight the role of human activities that alter the rate or direction of system response to climate change. Understanding and anticipating nonlinear dynamics are important aspects of adaptation planning since responses of biological resources to changes in the physical climate system are not necessarily proportional and sometimes, as in the case of complex ecological systems, inherently nonlinear.
