    Full Text Available Macular amyloidosis is an important cause for cutaneous pigmentation, the aetiology of which is poorly understood. Friction has recently been implicated the causation of early lesions, referred to as frictional amyloidosis. Confirmation of diagnosis by the detect on of amyloid using histochemical stains is inconsistent. Ten patients with pigmentation suggestive of macular amyloidosis were studied with detailed history, clinical examination, biopsy for histochemistry and electron microscopy. Nine out of ten patients had a history of prolonged friction with various objects such as bath sponges, brushes, towels, plant sticks and leaves. Amyloid was demonstrated by histochemical staining in only six out of ten cases. In the remaining four cases, amyloid was detected by electron microscopy. These consisted of aggregates of non-branching, extracellular, intertwining fibres measuring between 200-500 nm in length and between 20-25 nm in diameter. The study confirms the role of friction in the causation of this condition. Histochemical stains are not always successful in the detection of amyloid and electron microscopy is helpful for confirming its presence. The term frictional amyloidosis aptly describes the condition.

  2. Aid and Reform in Africa: Lessons from Ten Case Studies

    Science.gov (United States)

    2001-01-01

    Released on March 28, 2001, this new World Bank report investigates the impact of development aid on economic policy in ten African countries. Among the findings is the discovery that in nations where political leaders are not committed to reform, aid can actually hinder development by insulating these countries from the need to adopt reforms. The report also concludes that using "conditionality" to force reforms has largely failed and that, by and large, successful economic policies and reforms have been developed domestically by committed political leaders rather than introduced from the outside.

    1950-03-17

    In this report ten cases of acute radiation syndrome are described resulting from two accidents occurring at the Los Alamos Scientific Laboratory of unique nature involving fissionable material. These cases are described in considerable detail. The report comprises ten sections. This volume, part II of the report, is comprised of sections entitled: (1) the Biological Basis for the Clinical Response seen in the Acute radiation Syndrome, (2) Clinical Signs and Symptoms, (3) Discussion of Hematological Findings, (4) Chemistry of the Blood and Urine, (5) Discussion of Pathological Findings, and (6) Reconsiderations of the Calculated Radiation Doses in Terms of the Observed Biological Response of the Patients. This report was prepared primarily for the clinician who is interested in radiation injuries and therefore emphasis has been placed on the correlation of clinical and pathological changes with the type of cytogenetic change known to be produced by ionizing radiation.

    This report discusses the activities of organizations that seek to promote integrated resource planning and aggressive, cost-effective demand-side management by utilities. The activities of such groups -- here called energy efficiency advocacy groups (EEAGs) -- are examined in ten detailed am studies. Nine of the cases involve some form of interactive effort between investor-owned electric utilities and non-utility to develop policies, plans, or programs cooperatively. Many but not all of the interactive efforts examined are formal collaboratives. In addition, all ten cases include discussion of other EEAG activities, such as coalition-building, research, participation in statewide energy planning, and intervention in regulatory proceedings.

  10. Enabling frameworks for low-carbon technology transfer to small emerging economies: Analysis of ten case studies in Chile

    International Nuclear Information System (INIS)

    Technology transfer is crucial to reduce the carbon intensity of developing countries. Enabling frameworks need to be in place to allow foreign technologies to flow, to be absorbed and to bring about technological change in the recipient country. This paper contributes to identifying these enabling factors by analysing 10 case studies of low-carbon technology transfer processes based in Chile. Our findings show the importance of strong economic and institutional fundamentals, a sound knowledge base, a sizable and stable demand and a functioning local industry. Policy recommendations are derived to improve the penetration of foreign low-carbon technologies in developing countries, focusing on the particularities of small and medium emerging economies. - Highlights: ? We analyse 10 case studies of low carbon technology transfer to Chile. ? We identify enablers of technology transfer to developing countries. ? We provide policy recommendations focusing on small and medium economies.

    Full Text Available Herpes zoster occurs due to reactivation of the latent varicella zoster virus and is usually a disease of the elderly. Childhood herpes zoster is believed to be rare, though recent studies suggest increasing incidence in children. Here we report ten cases of childhood herpes zoster, seven of which occurred within a short span of six months, at a tertiary care level hospital in Pokhara, Nepal. Only three of the ten children reported previous history of varicella infection and none was immunized against varicella. Though childhood herpes zoster accounted for less than 1% of the total zoster cases in the past, recent reports show an increase in the number of cases in apparently healthy children. So far, no studies have been done linking childhood herpes zoster with HIV, though there are many studies linking it with other immunocompromised conditions.

    2015-02-01

    This study examines the effects of a borderline-specific treatment, called general psychiatric management, on emotional change, outcome and therapeutic alliance of an outpatient presenting with borderline personality disorder. Based on the sequential model of emotional processing, emotional states were assessed in a 10-session setting. The case showed an increase in expressions of distress and no change in therapeutic alliance and tended towards general deterioration. Results suggest emotional processing may play a lesser role in general psychiatric management in early phase treatment than previously hypothezised. PMID:25711648

    2011-01-01

    We have carried out optical (R band) intraday variability (IDV) monitoring of a sample of ten bright low energy peaked blazars (LBLs). Forty photometric observations, of an average of ~ 4 hours each, were made between 2008 September and 2009 June using two telescopes in India. Measurements with good signal to noise ratios were typically obtained within 1-3 minutes, allowing the detection of weak, fast variations using N-star differential photometry. We employed both structure function and discrete correlation function analysis methods to estimate any dominant timescales of variability and found that in most of the cases any such timescales were longer than the duration of the observation. The calculated duty cycle of IDV in LBLs during our observing run is ~ 52%, which is low compared to many earlier studies; however, the relatively short periods for which each source was observed can probably explain this difference. We briefly discuss possible emission mechanisms for the observed variability.

  16. Lessons learnt from ten performance assessment studies

    International Nuclear Information System (INIS)

    The management of radioactive wastes and, in particular, the safety assessment of radioactive waste disposal systems are areas of high priority in the programme of the OECD Nuclear Energy Agency (NEA). In 1994, a Working Group was set up under the PAAG (Performance Assessment Advisory Group) on Integrated Performance Assessments of Deep Repositories (IPAG). The aim of the group is to provide a forum for informed discussion on performance assessment (PA), and to examine the overall status of PA and specific issues identified by the group and the PAAG. This document presents the report of a first phase of work completed in December 1996 and is expected to be of most interest to practitioners of repository PA and those with an interest in technical review of PA studies.

    Full Text Available Objective: Cerebral hydatid disease is a rare manifestation of echinococcosis but it constitutes a significant part of all intracranial mass lesions. This study aims to determine the clinical, radiological and surgical features of brain hydatidosis and share our experience.Method: Medical records of ten patients with cerebral hydatid disease were retrospectively reviewed. Clinical presentations, radiological examinations, treatment modalities and outcomes of the patients were analyzed.Results: All patients were admitted from the rural areas. Nine patients had E. Granulosus cyst and one patient had E. Multilocularis cyst. The cyst was solitary in nine patients and multiple in one. Multiple organ involvement was found in one patient. Cysts were located in the right cerebral hemisphere in five patients, left cerebral hemisphere in four patients and posterior fossa in one. All patients were treated surgically. Complications related to surgery were observed in four patient. All patients improved after the treatment. There were no recurrences or residual cysts among the patients.Conclusion: Hydatic disease should considered in the differential diagnosis of intracranial space occupying lesions in developing countries. Early diagnosis of cerebral hydatid cysts may prevent serious life-threatening complications of this disease. Outcome is favourable when the cyst is completely removed without rupture.

    Full Text Available CONTEXT: Primary central nervous system lymphomas (PCNSL are a rare subgroup of lymphomas generally associated with HIV and EBV. OBJECTIVE: To study ten autopsy cases of PCNSL, to describe the neuropathological findings, to characterize the phenotype of the neoplastic cells, to detect EBV in the lesion and to compare the findings with the clinical and laboratory data of the patients. METHOD: The clinical, histological and immunohistochemical data of ten cases of PCNSL, eight cases from patients with AIDS, identified among 265 autopsies of these patients were analyzed. RESULTS: Seven patients were males and the mean age was 40.9 years. The most frequent symptomatology was focal neurologic deficit (70%. Six patients presented with only one lesion. Histologically, densely cellular and polymorphous neoplasms with angiocentrism were observed, in 90% of cases. An association with other diseases was observed in four cases. Most patients had diffuse large B cell non-Hodgkin’s lymphoma. EBV was detected by immunohistochemistry in only one case. The lack of detection of the virus might have been due to the long time of fixation of the brain which might have inactivate epitopes therefore compromising the testing. CONCLUSION: In the present series, PCNSL presented with focal symptoms, with unifocal or multifocal lesions, with a predominant B-cell CD20 positive phenotype, rarely associated with EBV.CONTEXTO: Linfoma primário do sistema nervoso central (LP-SNC é raro subgrupo de linfomas relacionado à AIDS, geralmente associado EBV. OBJETIVO: Identificar os achados clínico-patológicos dos pacientes com LP-SNC. MÉTODO: Foram analisados dados clínicos, histológicos e imuno-histoquímicos de dez necrópsias de LP-SNC, oito deles de pacientes com AIDS, identificados entre 265 autopsias destes. RESULTADOS: Sete pacientes foram masculinos e a idade média foi 40,9 anos. A sintomatologia neurológica mais freqüente era focal (70%. Seis exibiram lesão única. Histologicamente, eram neoplasias densamente celulares e polimorfas, com angiocentrismo em 90% dos casos. Em quatro casos, houve associação com outras afecções. A maioria dos casos foi de linfoma não-Hodgkin difuso de grandes células B. A pesquisa para EBV foi positiva em um caso. CONCLUSÃO: Predominaram os LP-SNC associados à AIDS, com sintomatologia focal, lesão em massa ou multifocal, com predominância de células B CD-20.

    Full Text Available Background: Lymphangioleiomyomatosis (LAM of the lung is a very rare disease ofunknown etiology which occurs particularly in women of childbearing age.So far, there have been very few reports of LAM in Taiwan.Methods: Data on all patients with a clinical or pathological diagnosis of LAM inChang Gung Memorial Hospital from 1990 to 2001 were collected from thepathology files or by consultation with thoracic surgeons, chest physicians,and radiologists of this institution. Cases were confirmed by lung biopsy andhigh-resolution computed tomographic scanning. Clinical data were obtainedfrom patients' charts. Additional immunostaining for HMB-45 antigen, estrogenreceptor, and progesterone receptor was carried out for cases with availableparaffin blocks.Results: In total, 10 patients confirmed with a diagnosis of LAM and adequate clinicalfollow-up information were found from 1991 to 2001. All were femalesof fertility age. The follow-up periods ranged from 18 to 167 months. Sixpatients received hormonal therapy. According to the pulmonary functiontests and clinical symptoms, 6 patients were in stable condition and 4 showedslow progression of disease by the time of the last follow-up. Two patientsdied after lung transplantation and abdominal surgery for retroperitonealLAM, respectively, at another medical center.Conclusions: The clinicopathological features of our series are similar to those reportedfrom other countries. The clinical course was slowly progressive with no significantresponse to hormonal therapy. Lung biopsies are important for adiagnosis, but the size and location of the biopsy specimens greatly affect thediagnostic reliability.

    Transcutaneous electrical nerve stimulation (TENS) is extensively used as pain relief through endorphins release. Moreover, recent findings showed a role in the activation of the autonomic nervous system (ANS); it was evidenced by modification in the heart rate variability and ANS-related marker. The objective of this pilot study is to evaluate salivary alpha amylase (sAA) as a marker of stress in two groups of healthy subjects, one receiving ultra-low frequency transcutaneous electrical nerve stimulation (ULF-TENS) and one without stimulation. Sixty healthy people were enrolled. The test group consisted of 30 participants (15 men, 15 women). The control group consisted of 30 participants (15 men, 15 women). Statistical analysis showed that sAA levels were statistically different between men and women independently from TENS; we hypothesize that treatment could influence sAA levels because it is thought to activate ? opioid receptors. The results of this study seem to indicate that the analysis of sAA, through a non-invasive saliva sample, could be an efficient aid for understanding the functions of the autonomic nervous system.

    Full Text Available Abstract Introduction Hydatid disease is a parasitic infection caused by the tapeworm Echinococcus granulosus and is characterised by cystic lesions in the liver and lungs. Concomitant pulmonary and hepatic localization of hydatid cysts in childhood is unusual and represents a distinct clinical entity called hepatopulmonary hydatidosis. Case presentation A ten-year-old Caucasian girl, a permanent resident of rural Greece, was admitted to hospital reporting a nonspecific symptomatology compatible with a diagnosis of viral infection. Chest radiography revealed a large homogenous circular opacity in the right lung field. On the basis of imaging studies, a diagnosis of hydatidosis was made with synchronous hepatic and pulmonary involvement, successfully managed through a single-stage transthoracic surgical approach. Conclusion This case report highlights the necessity of realizing that hydatid disease continues to be a public health problem, which often remains asymptomatic for years. Therefore, the presence of any homogeneous cystic spherical opacity on routine chest radiography should raise the suspicion of hydatid disease, mainly in endemic areas such as Greece. General practitioners and physicians involved in pediatric care need to be familiar with the diagnosis and management of the variable clinical manifestations of hydatid disease. Taking into consideration that hepatopulmonary hydatidosis represents a special entity that requires a different therapeutic approach may positively affect its economic and social-related burden.

    Background The biomechanical characteristics of midshaft clavicular fractures treated with titanium elastic nail (TEN) is unclear. This study aimed to present a biomechanical finite element analysis of biomechanical characteristics involved in TEN fixation and reconstruction plate fixation for midshaft clavicular fractures. Methods Finite element models of the intact clavicle and of midshaft clavicular fractures fixed with TEN and with a reconstruction plate were built. The distal clavicle displacement, peak stress, and stress distribution on the 3 finite element models were calculated under the axial compression and cantilever bending. Results In both loading configurations, TEN generated the highest displacement of the distal clavicle, followed by the intact clavicle and the reconstruction plate. TEN showed higher peak bone and implant stresses, and is more likely to fail in both loading configurations compared with the reconstruction plate. TEN led to a stress distribution similar to that of the intact clavicle in both loading configurations, whereas the stress distribution with the reconstruction plate was nonphysiological in cantilever bending. Conclusions TEN is generally preferable for treating simple displaced fractures of the midshaft clavicle, because it showed a stress distribution similar to the intact clavicle. However, TEN provides less stability, and excessive exercise of and weight bearing on the ipsilateral shoulder should be avoided in the early postoperative period. Fixation with a reconstruction plate was more stable but showed obvious stress shielding. Therefore, for patients with a demand for early return to activity, reconstruction plate fixation may be preferred. PMID:25965409

  10. Ten years of Developing International Volcanology Graduate Study Programs

    Science.gov (United States)

    Rose, W. I.

    2010-12-01

    In 2000 I reported at this symposium about multi-institutional graduate field trips to IAVCEI events, such as the Bali meeting and its importance in building international collegiality and awareness among the volcanology doctoral students. NSF was an enthusiastic supporter of these field sessions and this support has continued through the highly successful Pucon and Reykjavik sessions. International volcanology graduate program development began with several exchange programs. EHaz was a highly successful program (McGill, Simon Fraser, Michigan Tech, Buffalo, UNAM and Universidad de Colima) funded by the Department of Education (FIPSE) that moved students across North America where dozens of graduate students spent semesters of their study abroad and shared annual field trips and online student led graduate seminar classes. Michigan Tech’s volcanology graduate program started a Masters International program that combined Peace Corps service with hazards mitigation graduate study and students were placed by Peace Corps in countries with prominent natural hazards. The new program funded 2 year residences in foreign environments, principally in Pacific Latin America. NSF strongly supported this program from its inception, and eventually it gained NSF PIRE support. Dozens of students have initiated the 3 year program (15 completed) to date. A similar PIRE developed at UAF with a link to volcanology in the Russian Far East. One gain is the development of many socially-conscious research selections. Beginning this year transatlantic dual degree masters programs in volcanology are being offered by a consortium of US and European volcanology programs (Michigan Tech, Buffalo, Clermont Ferrand and University of Milan Bicocca), again aided by FIPSE funding. Students have dual advisors on both sides of the Atlantic and spend about half of their two year programs in Europe and half in US. Faculty also travel in the program and the four campuses are increasingly linked by coursework and research networks. Because the international developments of volcanology programs address the need for more robust coursework and research choices for students than are possible on one campus, and because they lead to a diverse network of professional contacts , we think the next decade will bring many more multi-university volcanology programs linked to field sites all over the world.

    Full Text Available Background: Acute lymphoblastic leukemia (ALL is the most common cancer in the pediatric population. With modern treatments, the chance of the complete recovery is nearly 100%. The most important prognostic factors are appropriate treatment protocol and determination of patient risk factors based on clinical, morphological, immunological and cytological characteristics. In this study we reviewed frequency of these factors, like as age, gender, the primary white blood cell number, sub- group on the base of FAB classification, immunophenotype and the clinical progress. Methods: In this retrospective study, we reviewed 877 pediatric patients with the diagnosis of ALL between the years of 1994 and 2004. In these patients the age, gender, primary WBC count, sub-group based on the FAB classification, immunophenotype and the clinical progress in 177 patient with acute lymphoblastic leukemia at Imam Khomeini Hospital between the years of 1994 to 2004 were determined. Results: Of these patients, 1.6% was younger than one year, 24.8% more than ten years old and 73.6% were between the ages of one and ten years; 63.8% were male. WBC counts were above 50,000/ul in 28.8% of the patients. FAB classifications included L1 in 80.2%, L2 in 17.5% and L3 in 2.3% of the patients. Immunophenotypes included pre-B cell in 63.8%, early pre-B cell in 23.1%, T cell in 12.3% and mature B cell in 0.8% of the patients. Marker CD10+ was detected in 88.1% of the B cell cases.

Em oncologia pediátrica, entretanto, são pouco identificadas. O tumor de Wilms é uma neoplasia renal comum em crianças e associa-se com mutações do gene WT1. A correla [...] ção entre tumor de Wilms e alterações do gene p53 não está bem estabelecida, sendo baixa a freqüência tumoral, podendo haver associação com doença em estágio avançado e histologia desfavorável. TIPO DE ESTUDO: Relato de caso. RELATO DE CASO: Foi realizar uma triagem para mutações do gene p53 pelo método de PCR-SSCP e seqüenciamento de DNA nos casos sugestivos de mutação em tumor de Wilms. Avaliação do gene p53 nos exons 5-9 em amostras de DNA extraídos de 10 tumores de Wilms de crianças em diferentes estágios pelo método de PCR-SSCP e seqüenciamento de DNA. Alterações na análise do SSCP foram observadas em duas amostras no exon 8. As prováveis mutações não foram confirmadas pelo seqüenciamento de DNA. A ausência de mutações de ponto do gene p53 observada nas 10 amostras de tumor de Wilms estudadas está de acordo com a literatura, sendo o seqüenciamento de DNA fundamental para a confirmação de possíveis mutações. Abstract in english CONTEXT: Mutations of the p53 tumor suppressor gene are the most frequent alterations observed in human neoplasias affecting adults. In pediatric oncology, however, they have seldom been identified. Wilms’ tumor is a renal neoplasia commonly occurring in children and is associated with mutations of [...] the WT1 gene. The correlation between Wilms’ tumor and alterations of the p53 gene has not been well established, with a low frequency of mutations having been reported in this type of tumor. Mutation may be associated with advanced stage disease and unfavorable histology. OBJECTIVE: To screen for mutations of the p53 gene by the PCR-SSCP method and DNA sequencing in cases of Wilms’ tumor sug-gestive of mutation. DESIGN: Case Report. CASE REPORT: Evaluations of exons 5-9 of the p53 gene in DNA samples extracted by PCR-SSCP from 10 Wilms’ tumors in children at different stages, and DNA sequencing. Changes in SSCP analy-sis were observed in exon 8 in two samples. The probable muta-tions were not confirmed by DNA sequencing. The absence of point mutations in p53 gene observed in the 10 samples of Wilms’ tumor studied agrees with literature data, with DNA sequencing being of fundamental importance for the confirmation of possible mutations.

Most of authors believe it is a mixture of indigo (blue and indirubin (red that becomes purple. Previous study showed that PUBS occurred predominantly in chronically catheterized, constipated women. We collected 10 elderly patients with PUBS in two nursing homes. The first two cases were identified by chart review in 1987 and 2003, and then later eight cases (42.1% were collected among 19 urinary catheterized elderly in the period between January 2007 and June 2007. In the present report, PUBS probably can occur in any patients with the right elements, namely urinary tract infection (UTI with bacteria possessing these enzymes, diet with enough tryptophan, and being catheterized. Associations with bed-bound state, Alzheimer’s, or dementia from other causes are reflections of the state of such patients who are at higher risk for UTI, and hence PUBS occurred. Although we presented PUBS as a harmless problem, prevention and control of the nosocomial catheter-associated UTIs (CAUTIs has become very important in the new patient-centered medical era. Thus, we should decrease the duration of catheterization, improve catheter care, and deploy technological advances designed for prevention, especially in the elderly cared for in nursing homes.Keyword: purple urine bag syndrome, indigo, indirubin, nursing home, bacteriuria, indoxyl sulphatase/phosphatase, nosocomial catheter-associated UTIs

    DEFF Research Database (Denmark)

    Birch, Emilie; Andersson, Mikael

    2014-01-01

    BACKGROUND: The incidence of tuberculosis (TB) disease in Greenland doubled in the 1990s. To combat the increase, national TB interventions were initiated in 2000 and strengthened in 2007. OBJECTIVE: To determine whether the effect of interventions could be detected, we estimated the TB disease risk among children?15 years before and after interventions were implemented. DESIGN: For a study cohort, we recruited all children ?15 years of age included in the Greenlandic Civil Registration System (CRS) from 1990 to 2010. The CRS identifier was used to link cohort participants with TB cases identified based on the Greenlandic National TB registry. Bacille Calmette Guerin (BCG) vaccination status was identified through year of birth, as BCG was offered to newborns born either before 1991 or after 1996. Years with interventions were defined as 2000-2006 (primary interventions) and 2007-2010 (intensified interventions). Risk of TB was estimated using Poisson regression. RESULTS: The study included 35,858 children, of whom 209 had TB disease. The TB disease incidence decreased after interventions were implemented (2007-2010: IRR [incidence rate ratios] 0.62, 95% CI: 0.39-0.95, p=0.03, compared with the 1995-1999 period). The TB disease risk was inversely associated with BCG vaccination (IRR: 0.54, 95% CI: 0.41-0.72, p<0.001). CONCLUSIONS: Years with national TB interventions in Greenland, including neonate BCG vaccination, are associated with a lower TB disease incidence among children ?15 years of age.

  7. Case ten. Should two competing neighboring hospitals consolidate their emergency services?

    Science.gov (United States)

    Tibbetts, P L

    1990-01-01

    Two hospitals sit together on a medical campus located in a large metropolitan area. The larger (746 beds) of the hospitals, St. Catherine's, was established in 1887 by a Catholic congregation of religious women. The other hospital (527 beds), Martindale, was established by a group of Lutheran pastors in 1916. The missions of the two hospitals are very similar. The hospitals are strategically located in the center of a metropolitan area. The marketplace is one which has been characterized as fiercely competitive, with 40 percent of the market enrolled in prepaid plans. The demand for hospital services continues to decline each year. There is significant over capacity in the metropolitan area, with an average occupancy around 50 percent. The hospitals have had a varied history of both cooperation and competition. In 1975, a joint venture organization was established to jointly share expensive technology and develop new shared programs. After a brief study of the declining volumes and profitability in both hospital emergency rooms and identifying that both were perceived as substandard by the public and by the physicians, the question became--"should two competing, neighboring hospitals consolidate their emergency services?" The case reports a problem commonly experienced by hospitals today--when to compete, when to collaborate and how to balance the two in pursuit of organizational competence and advantage.

    Full Text Available Abstract Background Suppression of immune system in treated cancer patients may lead to secondary infections that obviate the need of antibiotics. In the present study, an attempt was made to understand the occurrence of secondary infections in immuno-suppressed patients along with herbal control of these infections with the following objectives to: (a isolate the microbial species from the treated oral cancer patients along with the estimation of absolute neutrophile counts of patients (b assess the in vitro antimicrobial activity medicinal plants against the above clinical isolates. Methods Blood and oral swab cultures were taken from 40 oral cancer patients undergoing treatment in the radiotherapy unit of Regional Cancer Institute, Pt. B.D.S. Health University, Rohtak, Haryana. Clinical isolates were identified by following general microbiological, staining and biochemical methods. The absolute neutrophile counts were done by following the standard methods. The medicinal plants selected for antimicrobial activity analysis were Asphodelus tenuifolius Cav., Asparagus racemosus Willd., Balanites aegyptiaca L., Cestrum diurnum L., Cordia dichotoma G. Forst, Eclipta alba L., Murraya koenigii (L. Spreng. , Pedalium murex L., Ricinus communis L. and Trigonella foenum graecum L. The antimicrobial efficacy of medicinal plants was evaluated by modified Kirby-Bauer disc diffusion method. MIC and MFC were investigated by serial two fold microbroth dilution method. Results Prevalent bacterial pathogens isolated were Staphylococcus aureus (23.2%, Escherichia coli (15.62%, Staphylococcus epidermidis (12.5%, Pseudomonas aeruginosa (9.37%, Klebsiella pneumonia (7.81%, Proteus mirabilis (3.6%, Proteus vulgaris (4.2% and the fungal pathogens were Candida albicans (14.6%, Aspergillus fumigatus (9.37%. Out of 40 cases, 35 (87.5% were observed as neutropenic. Eight medicinal plants (A. tenuifolius, A. racemosus, B. aegyptiaca, E. alba, M. koenigii, P. murex R. communis and T. foenum graecum showed significant antimicrobial activity (P P. aeruginosa was observed highest susceptible bacteria (46.6% on the basis of susceptible index. Conclusion It can be concluded that treated oral cancer patients were neutropenic and prone to secondary infection of microbes.

The tumors were located at cerebellopontine angle (CPA zone (n = 5, parietal lobe (n = 1, tuberculum sella (n = 1, jugular foramen (n = 1, tentorium of cerebellum (n = 1 or lateral cerebral ventricle (n = 1. The initial symptoms included headache (n = 4, gait disturbance (n = 2, hearing loss (n = 2, vision loss (n = 1 and bucking (n = 1 which were associated with the mass locations. Results CT (n = 8 and MRI (n = 10 of 10 patients were retrospectively reviewed. CT findings of the lesions presented with hyperdensity (n = 6, isodensity (n = 1, or isodensity with hyperdensity (n = 1. MRI T1WI showed isointensity (n = 4, hypointensity with isointensity (n = 4 or hyperintensity (n = 2, whereas T2WI isointensity with hyperintensity (n = 7, presented hypointensity (n = 1, isointensity (n = 1, or hyperintensity (n = 1. On gadolinium-enhanced T1WI, moderate enhancement was seen in 8 lesions and marked enhancement was seen in 2 lesions. In initial CT scanning peritumoral edema was found in 7 cases, dural tail sign in 5 cases, cysts in 7 cases, calcification in 3 cases, periosteal proliferation in 1 case and bone destruction in 5 cases. Seven patients underwent complete resection and 3 underwent subtotal resection. Follow-up period was 11-120 months. Recurrence occurred in 5 patients. The mean recurrence time was 55.62 months. Conclusion Clear cell meningioma is a rare meningioma and often occurs in young persons without significant difference in sex. The CPA zone is the most affected area. The prognosis is closely related to the extent of resection. Clear cell meningioma tends to present marked enhancement, peritumoral edema, cystic components, and bone involvement in imaging findings?

  11. Geomagnetic response to solar activity: summary for the last ten years and analysis of selected cases

    The main sources of geomagnetic disturbances are either coronal mass ejections (CMEs), which are usually connected with eruptive flares, or high-speed streams of solar wind from coronal holes. Development of an eruptive flare and ejection of coronal mass is accompanied by magnetic reconnection. The evidence of reconnection can be found in a broad spectrum of observations. The observations of X-rays and radio bursts were used in our study. The geoeffectiveness of solar X-ray flares was initially analysed on data from the period 1996 - 2004 [1]. It was shown that the probability of geomagnetic response depends on the solar flare class and its position on the solar disc. The flares in the central region were found to be more geoeffective. The probability further increased if the flare was accompanied by Type II and/or Type IV of solar radio bursts. In the next step a neural network model was developed to determine the probability, with which flares will be followed by the geomagnetic response of a particular intensity. Enhancement of solar energetic particle flux was added to the set of input parameters. The results indicated that X-ray flares accompanied by solar radio bursts represent a good proxy of CMEs [2, 3]. This conclusion was now confirmed by the data from the period 2005 - 2012. Coronal holes are stable formations that can survive over several solar rotations. Corotating interaction regions (CIRs) between fast and slow solar wind can thus periodically pass over the Earth and cause recurrent geomagnetic storms. This periodicity makes the forecasts of the geomagnetic disturbances much easier [4] than in the case of eruptive phenomena. Our analysis confirmed that the strongest magnetic storms are caused by CMEs. Nevertheless, many geomagnetic disturbances in the active part of solar cycle are influenced by sequences of CMEs and CIRs, which increase their strength. [1] Bochní?ek, J., P. Hejda and F.

    Efforts towards a quantification of tsunamis, even though it started about seventy-five years ago, is still a puzzling aspect, since there are several scales proposed to measure tsunami size that are confusing regarding the intensity or magnitude, or they are difficult to apply. In the present work, ten different studies that relate specifically to numerical modeling of tsunami prediction and handling in Greek areas are reviewed. Even though current knowledge cannot guarantee the appearance and severity of a tsunami, warnings about tsunamis and predicting them in general can become more attuned and warnings can be more specific, with the development of numerical modeling.

    Lipoblastoma is a rare benign soft tissue tumor encountered almost exclusively in infancy and early childhood. The location of tumors varies, but most occur in the extremities, trunk, head and neck. Less frequently, lipoblastomas have been reported in the mediastinum, the retroperitoneum and the inguinal region. Only 7 cases of lipoblastoma in the scrotum have been reported so far in the English literature, with none of the patients older than 8. We report an intrascrotal lipoblastoma in a 10 year-old boy. The differential diagnosis is discussed with reference to the literature. PMID:23772297

    This review is based on our experience with ten patients diagnosed with Goodpasture's disease (GD). Six of the patients presented with combined renal and pulmonary insufficiencies; in the remaining four patients the clinical findings were limited to renal involvement. Circulating anti-glomerular basement membrane (GBM) autoantibodies were detected at diagnosis in all patients. Two patients were double-positive for anti-GBM and anti-proteinase-3 neutrophil cytoplasmic antibodies (c-ANCA). Another patient was double positive for anti-GBM and anti-myeloperoxidase cytoplasmic antibodies (p-ANCA). Four patients with rapidly progressive glomerulonephritis underwent hemodialysis: two of these patients died 6 and 8months after diagnosis, and the other two required maintenance dialysis. The remaining six patients were administered variable combinations of plasma-exchange, corticosteroids, and immunosuppressive drugs, which resulted in a remarkable and progressive improvement in renal function and one-year renal survival in all of them. Building on these observations, we provide an update on this relatively rare, frequently severe, and sometimes lethal autoimmune disease of unknown etiology. GD patients typically present with rapidly progressive renal insufficiency and pulmonary hemorrhage. Involvement restricted to the kidneys alone, as in our series, is also seen. The unfailing immunological hallmark of the disease is the occurrence of circulating anti-GBM antibodies, whose titer is directly related to the clinical severity of GD. The antibodies are associated with serum ANCAs in 10% to almost 40% of GD patients, with double positivity indicative of a worse renal prognosis. The target antigen of anti-GBM antibodies is a component of the non-collagenous-1 (NC1) domain of the ?3 chain of type IV collagen, ?345NC1. The prevalent expression of this hexamer on the basement membrane of both the glomeruli and the pulmonary alveoli accounts for the frequently combined renal and pulmonary involvement. A strong positive association of GD with the HLA-DRB1*15:01 allele has been described, but the factor(s) responsible for the loss of self-tolerance to NC1 autoantigen has not yet been identified. A conformational change in the quaternary structure of the ?345NC1 likely plays a crucial role in triggering an immune response and justifies the proposed description of GD as an autoimmune "conformeropathy." The function of autoreactive T-cells in GD is poorly defined but may involve a shift from TH2 to TH1 cytokine regulation, such that affinity maturation and the antigen specificity of the antibody response are enhanced. The timely diagnosis of GD and the adoption of a triple therapeutic regimen comprising plasmapheresis, corticosteroids, and immunosuppressive drugs have remarkably improved the previously dismal outcome of these patients, resulting in a one-year survival rate of 70-90%.

    Allergen-specific immunoglobulin E (present in allergic sensitization) has a central role in the pathogenesis of allergic disease. We performed the first large-scale genome-wide association study (GWAS) of allergic sensitization in 5,789 affected individuals and 10,056 controls and followed up the top SNP at each of 26 loci in 6,114 affected individuals and 9,920 controls. We increased the number of susceptibility loci with genome-wide significant association with allergic sensitization from three to ten, including SNPs in or near TLR6, C11orf30, STAT6, SLC25A46, HLA-DQB1, IL1RL1, LPP, MYC, IL2 and HLA-B. All the top SNPs were associated with allergic symptoms in an independent study. Risk-associated variants at these ten loci were estimated to account for at least 25% of allergic sensitization and allergic rhinitis. Understanding the molecular mechanisms underlying these associations may provide new insights into the etiology of allergic disease.

    A ten-year longitudinal prospective study compared the effect of fluoride on dentition of 1,500 children from infancy through age 10 years. In Kalamazoo, Mich, and Oneida, NY, parallel groups were given a fluoride-vitamin supplement from infancy and from age 4 and compared with fluoridated water and control groups. Incidence of new caries activity in both deciduous and permanent teeth was measured by mean number of new decayed and filled teeth, as well as percentage of children with no caries throughout the periods studied. Prevalence of caries was also studied in six-year molars. The results indicate a consistent (and, for selected groups, a statistically significant) diminution in caries activity for both deciduous and permanent teeth for groups ranked from greatest retardation of caries to least: infant fluoride group, water fluoride group, age 4 fluoride group, and controls.

  4. Ten years of siting studies and public dialogue: the main lessons learnt at SKB

    International Nuclear Information System (INIS)

    It is more than 20 years since a co-ordinated nuclear waste management programme was set up in Sweden. Deep geological disposal of spent nuclear fuel in crystalline bedrock is the preferred option and an extensive R and D programme has been performed. A step-wise approach is being applied to development, technical demonstration and implementation of the disposal system. A key element of the programme is siting of the deep repository, which started in a focused manner almost ten years ago. Before that time a study-site drilling programme was performed 1977-85 and facilities for intermediate storage of the spent fuel (CLAB), final disposal of low and medium level waste (SFR) and underground research (Aespoe Hard Rock Laboratory) were sited during the 1980's [1, 2]. Thus, siting-related experiences to date within SKB encompasses: - Deep-drilling programme at about ten study-sites (1977-85). - Siting of CLAB, 1976-79. - Siting of SFR, 1980-83. - Siting of Aespoe HRL, 1986-90. - Feasibility studies on a voluntary basis in two municipalities in northern Sweden, Storuman and Mala, including local referenda 1995 and 1997. - Feasibility studies on a voluntary basis in six municipalities, Oesthammar, Nykoeping, Oskarshamn, Tierp, Hultsfred, Aelvkarleby, 1995-2001. By the end of this year SKB will present a comprehensive plan for the continuation of the siting programme at a few sites selected from the six municipalities where feasibility studies are now being finished.

    Full Text Available Abstract Background Medical school attrition is important - securing a place in medical school is difficult and a high attrition rate can affect the academic reputation of a medical school and staff morale. More important, however, are the personal consequences of dropout for the student. The aims of our study were to examine factors associated with attrition over a ten-year period (2001–2011 and to study the personal effects of dropout on individual students. Methods The study included quantitative analysis of completed cohorts and qualitative analysis of ten-year data. Data were collected from individual student files, examination and admission records, exit interviews and staff interviews. Statistical analysis was carried out on five successive completed cohorts. Qualitative data from student files was transcribed and independently analysed by three authors. Data was coded and categorized and key themes were identified. Results Overall attrition rate was 5.7% (45/779 in 6 completed cohorts when students who transferred to other medical courses were excluded. Students from Kuwait and United Arab Emirates had the highest dropout rate (RR?=?5.70, 95% Confidence Intervals 2.65 to 12.27;p? Absenteeism was documented in 30% of students, academic difficulty in 55.7%, social isolation in 20%, and psychological morbidity in 40% (higher than other studies. Qualitative analysis revealed recurrent themes of isolation, failure, and despair. Student Welfare services were only accessed by one-third of dropout students. Conclusions While dropout is often multifactorial, certain red flag signals may alert us to risk of dropout including non-EU origin, academic struggling, absenteeism, social isolation, depression and leave of absence. Psychological morbidity amongst dropout students is high and Student Welfare services should be actively promoted. Absenteeism should prompt early intervention. Behind every dropout statistic lies a personal story. All medical schools have a duty of care to support students who leave the medical programme.

    Ten oriental spices were analyzed for their element composition using X-ray fluorescence (XRF): nutmeg (Myristica fragrans), coriander (Coriandrum sativum), safflower (Carthamus tinctorius), caraway (Carum carvi), Sicilian sumac (Rhus coriaria), aniseed (Anisum vulgare), black pepper (Piper nigrum), cardamom (Elettaria cardamomum), cumin (Cuminum cyminum) and nigella (Nigella sativum). The spices were found to contain the following elements: Mg, Al, Si, P, S, Cl, K, Ca, Ti, Mn, Fe, Cu and Zn, with varying concentrations. Mutagenic studies using Salmonella typhimurium strains TA97a, TA98, TA100, and TA102 showed that the above spices have no base pair substitution mutagenic activity. However, a weak frameshift mutagenicity has been shown by nutmeg and a very weak oxidative mutagenic action has been revealed by cumin. PMID:14531636

    Full Text Available Background: There is scarcity of data of the epidemiology of leukaemia in Arab countries including Yemen. Understanding patterns of leukaemia underpins epidemiology and can provide insight into disease etiology. The aim of this research is to determine the epidemiologic pattern of adult leukaemia in Yemen. Methods: The research is a descriptive cross-sectional study. We analyzed the data of 702 adult patients with leukaemia, who were newly diagnosed over a ten-year period between October 1999 and October 2009 at the referral haematology centre in Sana’a at Al-Jomhori Teaching Hospital, according to type of leukaemia, age, sex, geographic distribution and time of diagnosis. Results: Acute Myeloid Leukaemia (AML was found to be the most common (45.1% followed by Chronic Myeloid Leukaemia (CML (26.5%, Acute Lymphoid Leukaemia (ALL (17.7% and Chronic Lymphoid Leukaemia (CLL (10.7%, respectively. There was an almost equal prevalence of AML and CML for males and females but males had significantly more cases of ALL and CLL (p =0.008. A significant variation in geographic pattern showed that the highest number of cases is seen the Central mountainous region and the least number of cases in the South-eastern region which is coastal and lowland (p<0.001. The seasonal variation showed that higher number of ALL cases was seen in the summer months (33% compared with other seasons (21% in the spring, 24.2% in autumn and 21.8% in winter. Conclusions: The pattern of adult leukaemia in Yemen is different from that seen in western countries which could be attributed to different environmental exposure. The geographic pattern indicates a possible role of certain environmental factors which warrant further investigations. The pattern of seasonal variation needs further studies for evaluating the seasonality.

    Toxic epidermal necrolysis (TEN) and Stevens-Johnson syndrome (SJS) are severe mucocutaneous eruptions. There is currently no defined optimal approach to wound care. The objective of this study was to evaluate silver dressings in the wound-care management of TEN and SJS/TEN syndrome overlap with a retrospective case review of nine patients with TEN and SJS/TEN overlap presenting to our institution. Nanocrystalline silver dressings appear to be useful in the rapid commencement of healing in these patients. TEN and SJS/TEN overlap are rare conditions. This contributed to a relatively small number of cases included in the study. The ease of application, antimicrobial properties and low frequency of change make nanocrystalline silver dressings ideal in TEN/SJS. PMID:25368980

    A case is presented of a 34-year-old man who developed weakness of the proximal muscles of the extremities, particularly lower, slight myalgia, and vegetative symptoms (dryness in the mouth). Those symptoms progressed within a month. On examination weakness of the muscles of the extremities was found as well as weak tendon reflexes, slight atrophy of muscles of the arms and thighs and apokamnosis. Edrophonium test was slightly positive. Electrostimulation revealed changes typical of the Lambert-Eaton syndrome: low amplitude of the compound muscle action potential on single stimulus, decreasing amplitude of the subsequent responses to 3 Hz stimulation, marked facilitation on 30 Hz stimulation. Neoplastic etiology was excluded by chest X-ray and CT, as well as by bronchoscopy, abdominal and prostatic USG, and thyroid USG and scintigraphy. Antibodies to AChR were not found in the serum. The titre of the antibodies against voltage-gated calcium channels was highly positive which was decisive in the diagnosing of the Lambert-Eaton syndrome. The patient was treated with pyridostigmine, corticosteroids, cyclophosphamide and immunoglobulins. Ten years of follow-up have fully confirmed the diagnosis of a non-neoplastic Lambert-Eaton syndrome. PMID:16794965

    This module takes the learner through seven case studies of flash flood events that occurred in the conterminous U.S. between 2003 and 2006. The cases covered include: * 30-31 August 2003: Chase & Lyon Counties, KS * 16-17 September 2004: Macon County, NC * 31 July 2006: Santa Catalina Mountains near Tucson, AZ * 25 December 2003: Fire burn area near San Bernardino, CA * 30 August 2004: Urban flash flood in Richmond, VA * 19-20 August 2003: Urban flash flood in Las Vegas, NV * 9 October 2005: Cheshire County, NH This module assists the learner in applying the concepts covered in the foundation topics of the Basic Hydrologic Sciences course. Some of the specific topics pertinent to these cases are the physical characteristics that make a basin prone to flash floods, basin response to precipitation, flash flood guidance (FFG), the relationship between wildfire and flash floods, and the relationship between urban development and flash floods. Related topics brought out in the cases include radar quantitative precipitation estimation (QPE), the National Weather Service Flash Flood Monitoring and Prediction (NWS FFMP) products, debris flows, impounded water, and interagency communications. The core foundation topics are recommended prerequisite materials since this module assumes some pre-existing knowledge of hydrologic principles. In particular, the Runoff Processes and Flash Flood Processes modules contain material directly related to these cases.

    Full Text Available Objective: To report the early postoperative results and long-termsurvival on ten patients undergoing hepatectomy for treatmentof non-colorectal and non-neuroendocrine hepatic metastases.The study was carried out by the General Surgery Service of theDepartment of Digestive Tract Surgery of the Teaching Hospital ofthe Faculdade de Medicina do ABC, Santo André, São Paulo, Brazil.Methods: Complete follow-up data were available on 28 patientswith hepatic metastases who were operated on between January2002 and January 2007. Ten patients presented non-colorectal andnon-neuroendocrine primary neoplasms, and comprised the sampleof this study. There were five males and five females, mean age of53 years (28 to 68 years. The right lobe was involved in five patientsand the left lobe in five individuals. The number of metastasesranged from one to four. All metastases were unilateral. All primarytumors were identified. The histological types were adenocarcinoma(n = 7, germinative tumor (n = 1, melanoma (n = 1 and sarcoma(n = 1. The primary sites were: gastric (n = 1, kidney (n = 1,adrenal (n = 1, breast (n = 2, testicle (n = 1, ovary (n = 2,acral melanoma (n = 1 and retroperitoneal sarcoma (n = 1. Allpatients presented metachronous metastases. The median intervalbetween primary tumor treatment and diagnosis of metastases was20 months (12 to 33 months. Six patients received chemotherapyand four patients underwent exclusively surgical treatment. Results:There were seven major hepatic resections (three or more Couinaudsegments and three minor hepatic resections. The operative timevaried from 180 to 425 minutes with a median duration of 240minutes. Five patients received transfusions; blood loss ranged from200 to 3,000 ml. There were two postoperative complications andboth patients were re-operated (biliary fistula = 1; intra-abdominalabscess = 1. There were no postoperative deaths. All resectionswere R0. The three-year overall survival rate was 50%. Five patientsdeveloped tumor recurrence (50%. Conclusions: Hepatic resectionfor liver metastases other than of colorectal or neuroendocrine originpresents acceptable morbidity and no mortality. This approach mayresult in long-term survival in this group of patients.

    Anne Jefferson

    To prepare for the case study, lecture material on coastal landforms and processes is presented. Particular attention is paid to barrier islands, such as the Outer Banks. During the lecture, typical coastal engineering structures, such as groins, breakwaters, and jetties, are introduced. The case study is introduced with a brief overview of North Carolina's coastal management laws, Figure Eight Island's geography, and the current controversy over whether to build a terminal groin. Students are then broken down into small groups and presented with two opposing editorials. The groups are instructed to try to come to consensus as to whether the terminal groin should be allowed or disallowed or to suggest a third alternative. After approximately 25 minutes, each group informally reports out to the rest of the class.

    2012-08-01

    Full Text Available Abstract Background Campylobacter jejuni and Campylobacter coli are food-borne pathogens of great importance and feature prominently in the etiology of developing world enteritis and travellers’ diarrhoea. Increasing antimicrobial resistant Campylobacter prevalence has been described globally, yet data from Peru is limited. Our objective was to describe the prevalence trends of fluoroquinolone and macrolide-resistant C. jejuni and C. coli stool isolates from three regions in Peru over a ten-year period. Methods Surveillance for enteric pathogens was conducted in Lima, Iquitos and Cusco between 2001 and 2010. Campylobacter stool isolates were tested for susceptibilities to ciprofloxacin, azithromycin and erythromycin. Susceptibilities were reviewed for 4652 isolates from Lima ( n?=?3419, Iquitos ( n?=?625 and Cusco ( n?=?608. Results Comparing the study periods of 2001-2005 and 2006-2010, prevalence of ciprofloxacin-resistant C. jejuni isolates rose in the study areas of Lima (73.1% to 89.8%, p?p?C. coli rates also increased in Lima (48.1% to 87.4%, p?p?=?0.005. Small but significant increases in azithromycin-resistant and erythromycin-resistant C. jejuni prevalence were noted in Iquitos (2.2% to 14.9%, p?p?=?0.002, and erythromycin-resistant C. coli rates increased in Lima (0.0% to 5.3%, p?=?0.038. The prevalence of C. jejuni isolates resistant to both ciprofloxacin and azithromycin increased in Iquitos (0.3% to 14.9%, p?C. jejuni isolates resistant to both ciprofloxacin and erythromycin rose in Iquitos (0.0% to 14.9%, p?C. coli prevalence increased in Lima (0.0% to 5.3%, p?=?0.034. Conclusions These results have implications for the empirical management of enterocolitis in Peru. Ongoing surveillance is essential to guide appropriate antimicrobial use in this setting. Local epidemiological studies to explore the relationship between increasing antimicrobial resistance and agricultural or human antibiotic use may be valuable.

    Directory of Open Access Journals (Sweden)

    Ibecheozor, N.K.O

    2014-09-01

    Full Text Available Malaria, which is transmitted by female Anopheles mosquitoes, is the major cause of mortality among the pregnant women in the sub-Saharan Africa. A ten year study of malaria in pregnancy was carried out in Abuja, North Central Nigeria. Thick and thin blood films were stained with the Giemsa methodology. Of the 16760 pregnant women blood samples, 4571 (27.3% were positive for malaria parasites caused by Plasmodium falciparum. Of the 4571 positive cases, 75 (1.7% had parasite density of >5000 parasites/µl of blood; 148 (3.2% had between 500-5000 parasites/µl of blood; 520 (11.4% had between 50 - 500 parasites/µl of blood; while 3828 (83.7% had between 5-50 parasites/µl of blood. With the current estimate of over 4500 deaths of pregnant women in Nigeria due to malaria annually, we must make deliberate efforts to stop these unacceptable and painful losses. The continued use of malaria rapid diagnostic tests (M-RDTs methodologies should be discontinued because of its negative implications. Therefore, the microscopic laboratory diagnostic component should be included in ANC at all level of health care facility.

  12. Multiple splenuculi - a case study

    International Nuclear Information System (INIS)

    Full text: A 79-year-old woman with chronic lymphocytic leukaemia (CLL) and thrombocytopenia secondary to chronic idiopathic thrombocytopenia (ITP) was referred for a denatured red blood cell study. Previous treatment included Prednisone, oral Cyclophosphamide and regular Intragam infusions as well as a splenectomy in 1996. The patient presented with multiple oral haemorrhages with active bleeding and petechiae on the chest wall. Her haemoglobin was 14.1g/dl, white cell count 6.6x10E9/l, and platelets 7x10E9/l. Her red blood cells were normochromic and contained moderate numbers of Howell-Jolly bodies, this was consistent with a post-splenectomy or hyposplenism. After the administration of autologous denatured technetium labelled red blood cells, an abdominal SPECT and planar images from the lung bases to mid femurs were acquired. The imaging showed evidence of approximately six small splenuculi in the left anterolateral aspect of the abdomen. A CT abdomen was performed following to assess suitability for surgery. Ten millimeter sections from the lung bases to the pelvis with intravenous and oral contrast demonstrated no splenuculi. As a result of the negative finding on CT, the patient was not considered for surgery as it was doubtful that surgeons would be able to locate the splenuculi. In conclusion, the denatured red blood cell study showed superior sensitivity and specificity for the detection of splenuculi. By the elimination of surgery, this case demonstrated tation of surgery, this case demonstrated the importance of correlation with other modalities in providing cost effective patient management.

    Full Text Available Abstract Background Reminiscence is the systematic use of memories and recollections to strengthen self-identity and self-worth. The study aim was to investigate the consequences for nursing home residents and staff of integrating reminiscence into daily nursing care. Methods In this randomised study, ten nursing homes were matched into two groups on the basis of location, type and size. In the period August 2006 - August 2007, staff in the Intervention Group were trained and supported in the use of reminiscence, involving individual and group sessions with residents as well as reminiscence boxes, posters and exhibitions. At baseline and again 6 and 12 months after the intervention start, data were collected on residents' cognitive level, agitated behaviour, general functioning and proxy-assessed quality of life, as well as on staff well-being and job satisfaction. Mixed linear modelling was used to analyse differences in outcome between the intervention and control groups. Results Project drop-out rates were 32% for residents and 38% for nursing staff. Most staff in the Intervention Group considered reminiscence a useful tool that improved their communication with residents, and that they would recommend to other nursing homes. There were no significant differences between residents in the Intervention and the Control Group in cognitive level, agitated behaviour or general functioning. Residents in the Intervention Group showed significant higher score at 6 months in quality of life subscale 'Response to surroundings', but there was no significant difference at 12 months. Positive effects of reminiscence were observed for all staff outcome measures, the only exception being SF-12 self-rated physical health. At 6 months after start of reminiscence, staff in the Intervention Group had significantly better scores than those in the Control Group for Personal accomplishment, Emotional exhaustion, Depersonalisation, 'Attitude towards individual contact with residents' and SF-12 self-rated mental health. At 12 months after start of reminiscence, staff in the Intervention Group had significantly better scores than those in the Control Group for Emotional exhaustion and 'Professional role and development'. Conclusions The use of reminiscence appeared to have little long-term effect on the nursing home residents. Nursing staff in the Intervention Group experienced greater satisfaction with professional roles and developed a more positive view of the residents.

  15. Ten-year study on varieties of parotid tumors in pediatrics

    International Nuclear Information System (INIS)

    Parotid tumors are uncommon because they account for 0.5 % of all types of cancer in pediatrics. They generally occur as increased local asymptomatic volume, occasionally accompanied by pain and inflammatory signs. A retrospective, longitudinal and descriptive study was carried out to determine the frequency and forms of presentation of parotid tumors diagnosed in 0-18 years-old patients, who had been admitted to the oncological surgery service of 'William Soler' pediatric hospital from February 2001 to December 2010. The variables taken into account were sex, forms of presentation, response to treatment as well as the histological variants presented, with the objective of giving information about these variants of parotid tumors in pediatrics, which, despite their rareness, represent a high risk group when occur. Seven patients were diagnosed, of whom 3 were pleomorphic adenomas, one adenocarcinoma, one mucoepidermoid carcinoma of the gland, one parotid Hodgkin lymphoma and one mixed tumor with atypical cells of the gland. The onset of all the tumors was the presence of a parotid mass in 6 asymptomatic cases and in one case suffering local pain. They were all performed gland ultrasound and aspiration fine needle biopsy. Males prevailed over the females (ratio of 5:2) and the average age of presentation was 12.3 years. Surgery is the main therapeutic weapon in most of cases. It was recommended to closely follow the patients because of their high rate of local recurrence

    Simonsen, Erik; ten Velden Hegelstad, Wenche

    2013-01-01

    Background: Poor symptom outcome remains a challenge in psychosis: At least 50% of first-episode patients continue to have positive and/or negative symptoms after ten years. Objective: To investigate rates, early predictors and early symptom progression of long-term non-remitted psychosis in an early detection study. Methods: Symptomatic remission according to new international criteria was assessed in 174 patients at ten-year follow-up. Remitted and non-remitted patients were compared on early symptom progression, and logistic regression was applied to predict non-remission. Results: At ten years, 50% of patients were in symptomatic remission. Non-remission was predicted by positive symptoms at inclusion and during the first year of treatment. Of individual symptoms only hallucinations were significantly predictive of ten-year non-remission. Early symptom differences were not reflected by differences in treatment. Conclusions: Long-term symptomatic non-remission is associated with early positive symptoms. More assertive intervention may be needed in patients who do not respond robustly in the first year of treatment, whether or not they have been detected “early”.

  20. Equity in HIV testing: evidence from a cross-sectional study in ten Southern African countries

    2010-09-01

    Full Text Available Abstract Background HIV testing with counseling is an integral component of most national HIV and AIDS prevention strategies in southern Africa. Equity in testing implies that people at higher risk for HIV such as women; those who do not use condoms consistently; those with multiple partners; those who have suffered gender based violence; and those who are unable to implement prevention choices (the choice-disabled are tested and can have access to treatment. Methods We conducted a household survey of 24,069 people in nationally stratified random samples of communities in Botswana, Lesotho, Malawi, Mozambique, Namibia, South Africa, Swaziland, Tanzania, Zambia, and Zimbabwe. We asked about testing for HIV in the last 12 months, intention to test, and about HIV risk behaviour, socioeconomic indicators, access to information, and attitudes related to stigma. Results Across the ten countries, seven out of every ten people said they planned to have an HIV test but the actual proportion tested in the last 12 months varied from 24% in Mozambique to 64% in Botswana. Generally, people at higher risk of HIV were not more likely to have been tested in the last year than those at lower risk, although women were more likely than men to have been tested in six of the ten countries. In Swaziland, those who experienced partner violence were more likely to test, but in Botswana those who were choice-disabled for condom use were less likely to be tested. The two most consistent factors associated with HIV testing across the countries were having heard about HIV/AIDS from a clinic or health centre, and having talked to someone about HIV and AIDS. Conclusions HIV testing programmes need to encourage people at higher risk of HIV to get tested, particularly those who do not interact regularly with the health system. Service providers need to recognise that some people are not able to implement HIV preventive actions and may not feel empowered to get themselves tested.

    Full Text Available The ultimate objective of manufacturing industries is to increase productivity with high quality. At present, many manufacturing companies are facing problems such as high quality rejection, high inventories, high lead time, high costs of production, and inability to cope with customer orders. By implementing and practicing the lean production system many problems can be solved without employing high-tech and high-touch approaches but by involving people on the shop floor in Kaizen activities. Kaizen is one of the powerful tools of lean manufacturing. Kaizen refers to continuous improvement in performance, cost and quality. Kaizen ensures that manufacturing processes become leaner and fitter, but eliminate waste (problem where value is added. The main objective of this paper is to provide a background on kaizen, present an overview of kaizen concepts that are used to transform a company into a high performing lean enterprise. A case study of implementation of Kaizen?s has been discussed.

    This article takes a retrospective look at how the folks in business schools look at the case method. The legacy of cases in business may seem short in the eyes of some but it is positively ancient when compared to the use of the case study in the sciences, which began to take hold in the 1990s. Surprisingly, in spite of its impeccable academic pedigree, there seems to be little literature on the success of the method; virtually no assessment data in business, law, or public policy teaching seems to exist.

  3. Ten-year experiences with Tracheostomy at a University teaching hospital in Northwestern Tanzania: A retrospective review of 214 cases

    Gilyoma Japhet M

    2011-11-01

    Full Text Available Abstract Background Tracheostomy remains a very important life saving surgical procedure worldwide and particularly in our environment where patients present late in upper airway obstruction. Little work has been done on this subject in our environment and therefore it was necessary to conduct this study to describe our own experiences with tracheostomy, outlining the common indications and outcome of tracheostomized patients in our setting and compare our results with those from other centers in the world. Methods This was a 10-year retrospective study which was conducted at Bugando Medical Centre from January 2001 to December 2010. Data were retrieved from patients' files kept in the Medical record department and analyzed using SPSS computer software version 15.0. Ethical approval to conduct the study was obtained from relevant authority before the commencement of the study. Results A total of 214 patients were studied. The male to female ratio was 3.1: 1. The majority of patients were in the 3rd decade of life. The most common indication for tracheostomy was upper airway obstruction secondary to traumatic causes in 55.1% of patients, followed by upper airway obstruction due to neoplastic causes in 39.3% of cases. The majority of tracheostomies (80.4% were performed as an emergency. Transverse skin crease incision was employed in all the cases. Post-tracheostomy complication rate was 21.5%. Complication rate was significantly higher in emergency tracheostomy than in electives (P Conclusion Upper airway obstruction secondary to trauma and laryngeal tumors still remains the most common indication for tracheostomy in our centre and tracheostomy is still a life saving procedure in the surgical management of airway despite complications which are seen more commonly in paediatric patients. Most of tracheostomy related complications can be avoided by meticulous attention to the details of the technique and postoperative tracheostomy care by skilled and trained staff.

    Full Text Available Introduction. Henoch-Schönlein purpura (HSP is the most common vasculitis of childhood. It is characterized by symptoms including nonthrombocytopenic purpura, abdominal pain, haematuria/proteinuria, and arthralgia/arthritis. The pleiomorphism of clinical signs in HSP could be confused with other conditions or other vasculitis forms. Objective. Evaluation of HSP clinical presentation, the onset and severity of renal manifestation in affected children and their outcome. Methods. A retrospective study of 49 patients diagnosed with HSP was conducted from September 1999 to September 2009. Children with severe renal manifestations (nephrotic range proteinuria, with or without nephrotic or nephritic syndrome have undergone kidney biopsy. Results. Twenty-five patients developed renal manifestations after onset of the disease. In our study child’s older age was a risk factor for association with HSP nephritis. Six of the patients required kidney biopsy. They were successfully treated with various immunosuppressive protocols, as well as three of nine patients with nephrotic range proteinuria. Two patients developed most severe form of HSP nephritis, nephrotic-nephritic syndrome with histology grade IIIb/IVb. During the study period (average follow-up 6 years, all patients had a normal global renal function with mild proteinuria in only two cases. The prognosis of renal involvement was better than reports from other patient series. Conclusion. Long-term morbidity of HSP is predominantly attributed to renal involvement. During the study period, no patient had renal insufficiency or end stage renal disease after various combinations of immunosuppressive treatment. It is recommended that patients with HSP nephritis are followed for longer periods of time with a regular measurement of renal function and proteinuria.

    Full Text Available During the past few years, Archaetnos has been involved in various land claims, with a view to collecting historical, anthropological and archaeological information in order to determine the validity of such claims. This was done by doing deeds searches and studying archival material and anthropolog [...] ical literature, followed by a field survey where claimants indicated sites linked to their history and where they were interviewed. In some cases it was clear from the onset that misperceptions about South African history pertain. Even when information is correct, there is sometimes chronological chaos and in certain instances so-called "facts" are being fabricated. The above-mentioned information is used by the Land Claims Commission (LCC) to determine the merit of a claim. The lack of knowledge at this institution frequently results in cases being approved for the process even when such approval was clearly based on incorrect information. The land claim of the BaPhalane Ba Ramokoka community is one such example. In the article the reasons for land claims in general are listed. The merit of the BaPhalane claim, as well as the information obtained during the research process, is then discussed against this background. This is, however, not done in detail, as the article insteadfocuses on the general problem created by historical misperceptions. The findings of the research were that although the BaPhalane had a valid claim to at least four of the thirty-two farms listed, they had no valid claim to at least eighteen others. This was confirmed by the court judgement. It is concluded that the lack of knowledge at the Land Claims Commission results in many cases being unnecessarily investigated. This results in high costs, a waste of time and an unproductive system. It is therefore clear that information is required at a much earlier stage during the land claims process.

  10. 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 asr 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

  11. 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 for states that have traditionally had 'less transparency' in their military sectors. As case studies, first we investigate how to applied verification measures including remote sensing, off-site environmental sampling and on-site inspections to monitor the shutdown status of plutonium production facilities, and what measures could be taken to prevent the disclosure of sensitive information at the site. We find the most effective verification measure to monitor the status of the reprocessing plant would be on-site environmental sampling. Some countries may worry that sample analysis could disclose sensitive information about their past plutonium production activities. However, we find that sample analysis at the reprocessing site need not reveal such information. Sampling would not reveal such information as long as inspectors are not able to measure total quantities of Cs-137 and Sr-90 from HLW produced at former military plutonium production facilities. Secondly, we consider verification measures for shutdown gaseous diffusion uranium-enrichment plants (GDPs). The GDPs could be monitored effectively by satellite imagery, as one telltale operational signature of the GDP would be the water-vapor plume coming from the cooling tower, which should be easy to detect with satellite images. Furthermore, the hot roof of the enrichment building could be detectable using satellite thermal-infrared images. Finally, some on-site verification measures should be allowed, such as visual observation, surveillance and tamper-indicating seals. Finally, FMCT verification regime would have to be designed to detect undeclared fissile material production activities and facilities. These verification measures could include something like special or challenge inspections or complementary access. There would need to be provisions to prevent the abuse of such inspections, especially at sensitive and non-proscribed military and nuclear activities. In particular, to protect sensitive information, it is essential to have an appropriate managed access mechanism, which should be able to re

  12. Triacylglycerols in some underutilised tropical seed oils 1. Systematic studies of ten oils

    International Nuclear Information System (INIS)

    Triacylglycerols composition of ten lesser known and underutilised tropical seed oils have been determined. The seed oils include Monodora tenuifolia, Monodora myristica, Colocynthis citrullus, Cyperus esculentus, Cucumeropsis edulis, Andenopus breviflorus, Telfairia occidentalis, Blighia sapida, Antiaris africana and Sesame indicum. In the Moreaceae family (M. tenuifolia, M. myristica) the dominant triacylglycerol are OPO/POO, LLO, OOL, and OOO. They accounted for over 60% of the total triacylglycerol content in the oils. In the Cyperaceae family (C. esculentus), OPP/POO, POL and OOO accounted for over 80% of the total triacylglycerol content. In the Cucurbitaceae family, SSP was the dominant triacylglycerol specie in A. breviflorus, while OPO/POO and OOO were the dominant species in C. citrullus and C. edulis. Blighia sapida recorded a different distribution of triacylglycerols composition. PLL occurred at the highest concentration, while other high molecular weight triacylglycerols were also identified in the oil. They include, SSA, OSA, LSA, OAA and LLA. Analysis of A. antiaris oil showed a different pattern in the distribution of the triacylglycerols. LaLaM, MMLa and LaLaLa accounted for about 80% of the total triacylglycerols. This result reflected the fatty acid composition of the oil. Lauric acid (C12:0) and Myristic acid (C14:0) accounted for 71.5% of the total fatty acid. The possible use of the oils as cocoa butter equivalents CBEs and cocoa butter substitutes CBSs are discussed. (author)

  13. Study of the stellar population properties in the discs of ten spiral galaxies

    Morelli, L; Pizzella, A; Bontà, E Dalla; Coccato, L; Méndez-Abreu, J

    2015-01-01

    We investigated the properties of the stellar populations in the discs of a sample of ten spiral galaxies. Our analysis focused on the galaxy region where the disc contributes more than 95 per cent of total surface brightness in order to minimise the contamination of the bulge and bar. The luminosity-weighted age and metallicity were obtained by fitting the galaxy spectra with a linear combination of stellar population synthesis models, while the total overabundance of {\\alpha}-elements over iron was derived by measuring the line-strength indices. Most of the sample discs display a bimodal age distribution and they are characterised by a total [{\\alpha}/Fe] enhancement ranging from solar and supersolar. We interpreted the age bimodality as due to the simultaneous presence of both a young (Age$\\,\\leq\\,4$ Gyr) and an old (Age$\\,>\\,$4 Gyr) stellar population. The old stellar component usually dominates the disc surface brightness and its light contribution is almost constant within the observed radial range. For...

    2014-01-01

    The appropriateness of case studies as a tool for theory testing is still a controversial issue, and discussions about the weaknesses of such research designs have previously taken precedence over those about its strengths. The purpose of the paper is to examine and revive the approach of theory testing using case studies, including the associated research goal, analysis, and generalisability. We argue that research designs for theory testing using case studies differ from theorybuilding case study research designs because different research projects serve different purposes and follow different research paths.

    2013-11-01

    Full Text Available Surveillance of antimicrobial agent resistance provides important information to guide microbiologists and infectious disease specialists understanding of the control and the spread of resistance mechanisms within the local environment. Continued monitoring of antimicrobial resistance patterns in the community and in local hospital environments is essential to guide effective empiric therapy. The Study for Monitoring Antimicrobial Resistance Trends (SMART has monitored the in vitro susceptibility patterns of clinical Gram-negative bacilli to antimicrobial agents collected worldwide from intra-abdominal infections since 2002 and urinary tract infections since 2009. Resistance trends, with a particular focus on carbapenem resistance and the rate of extended-spectrum ?-lactamases (ESBLs, were analyzed. Isolates from intra-abdominal infections (n = 92,086 and urinary-tract infections (n = 24,705 were collected and tested using Clinical and Laboratory Standards Institute methods. This review presents carbapenem susceptibility and ESBL rates over ten years of SMART study analysis, including key publications during this period. The SMART study has proved to be a valuable resource in determining pathogen prevalence and antibiotic susceptibility over the last ten years and continues to provide evidence for regulatory susceptibility breakpoints and clinical decision making.

  19. 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 a progressive way.

    Beckwée David

    2012-02-01

    Full Text Available Abstract Background Central sensitization has recently been documented in patients with knee osteoarthritis (OAk. So far, the presence of central sensitization has not been considered as a confounding factor in studies assessing the pain inhibitory effect of tens on osteoarthritis of the knee. The purpose of this study is to explore the pain inhibitory effect of burst tens in OAk patients and to explore the prognostic value of central sensitization on the pain inhibitory effect of tens in OAk patients. Methods Patients with knee pain due to OAk will be recruited through advertisements in local media. Temporal summation, before and after a heterotopic noxious conditioning stimulation, will be measured. In addition, pain on a numeric rating score, WOMAC subscores for pain and function and global perceived effect will be assessed. Patients will be randomly allocated to one of two treatment groups (tens, sham tens. Follow-up measurements will be scheduled after a period of 6 and 12 weeks. Discussion Tens influences pain through the electrical stimulation of low-threshold A-beta cutaneous fibers. The responsiveness of central pain-signaling neurons of centrally sensitized OAk patients may be augmented to the input of these electrical stimuli. This would encompass an adverse therapy effect of tens. To increase treatment effectiveness it might be interesting to identify a subgroup of symptomatic OAk patients, i.e., non-sensitized patients, who are likely to benefit from burst tens.

    This module takes the learner through the considerations for the river forecasting decisions associated with the remnants of Hurricane Ivan on 17-19 September, 2004 for the Susquehanna River system in Pennsylvania and New York. The module assists the learner with applying the concepts covered in the foundation topics of the Basic Hydrologic Sciences course. Some of the specific topics pertinent to this case are soil conditions, the impact of QPF on runoff, runoff models, runoff processes, routed flow and stage-discharge relationships. Observations of upstream conditions and comparisons to historic crests are also examined to assist with operational flood forecast decisions. The core foundation topics are recommended as a prerequisite since this module assumes some pre-existing knowledge of hydrologic principles.

    In response to the need for culturally competent care, faculty can instill in students the desire to become culturally competent practitioners by providing the opportunity to participate in a short-term study abroad immersion experience. While this strategy is not considered cutting-edge or revolutionary, changing global dynamics warrant rethinking this curricular option. Nurse faculty conducted two short-term study abroad courses in Croatia. Students explored health care and nursing education in this Eastern European country and participated in a service-learning project. Based on their experiences, the authors offer five dos and five don'ts for planning and implementing a successful study abroad course. PMID:22029242

    Full Text Available Abstract Background Congenital anomalies and their primary prevention are a crucial public health issue. This work aimed to estimate the prevalence of congenital anomalies in Brindisi, a city in southeastern Italy at high risk of environmental crisis. Methods This research concerned newborns up to 28 days of age, born between 2001 and 2010 to mothers resident in Brindisi and discharged with a diagnosis of congenital anomaly. We classified cases according to the coding system adopted by the European Network for the Surveillance of Congenital Anomalies (EUROCAT. Prevalence rates of congenital anomalies in Brindisi were compared with those reported by EUROCAT. Logistic regression models were adapted to evaluate the association between congenital anomalies and municipality of residence of the mother during pregnancy. Results Out of 8,503 newborns we recorded 194 subjects with congenital anomalies (228.2/10,000 total births, 1.2 times higher than the one reported by the EUROCAT pool of registries. We observed 83 subjects with congenital heart diseases with an excess of 49.1%. Odds Ratios for congenital heart diseases significantly increased for newborns to mothers resident in Brindisi (OR 1.75 CI 95% 1.30-2.35. Conclusions Our findings indicated an increased prevalence of Congenital Anomalies (especially congenital heart diseases in the city of Brindisi. More research is needed in order to analyze the role of factors potentially involved in the causation of congenital anomalies.

    DEFF Research Database (Denmark)

    Carlsen, Jack

    2007-01-01

    Innovation is the key to responding to the future challenges that confront all sectors of society and the economy, and especially in tourism. Within tourism, there are numerous corporations and destinations around the world that are responding to the ecological, social and economic challenges and making the transformation toward sustainability through innovation. This book assembles ten case studies of large and small enterprises and destinations in developed and developing nations that are pursuing innovative practices that will enhance the sustainability of their operations. The chapters in this volume are based on primary and secondary research by the contributing authors and each chapter has been peer reviewed prior to publication. Cross-case analysis (Patton 1990) was also used to provide a framework for comparing and contrasting the different types and contexts of innovation and provide for an integrated overview of the drivers, barriers, processes and networks for innovation. The cases have been prepared for use in research and teaching of innovation, and the analysis and case notes are both designed to facilitate discussion and further investigation of innovation, not only in tourism, but in other economic sectors as well. Being an online publication, it is expected that updates in successive editions of this first book will add further to the description and analysis of innovation for sustainable tourism and hence provide a resource for those seeking to enhance the teaching, research and practice of innovation.

    Patients with huge hepatocellular carcinoma >10 cm in diameter represent a special subgroup for treatment. To date, there are few data and little consensus on treatment strategies for huge hepatocellular carcinoma. In this study, we summarized the effects and safety of transarterial chemoembolization for huge hepatocellular carcinoma. A retrospective study was performed based on a large cohort of patients (n = 511) with huge hepatocellular carcinoma who underwent serial transarterial chemoembolization between January 2008 to December 2011 and were followed up until March 2013. We found median survival time was 6.5 months. On multivariate analysis, Child-Pugh class (A versus B) (p failure (n = 6). In conclusion, transarterial chemoembolization is a safe and effective treatment for selected patients with huge hepatocellular carcinoma and is recommended as a component of combination therapy. In addition, patients with good liver function and low alpha-fetoprotein levels may acquire greater survival benefits from transarterial chemoembolization. PMID:25682389

Personality profiles are useful, because personality traits may have different effects on depressive symptoms when combined with different combinations of other traits. Participants were from the population-based Young Finns study with repeated measurements in 1997, 2001, and 2007 (n = 1402 to 1902). TCI was administered in 1997 and mild depressive symptoms (modified Beck...

  16. Reproduction and production in a buffaloes farm of the Marche region: a ten-year study

    Full Text Available Water buffalo milk reproductive and productive traits are fundamental to evaluate farm efficiency and dairy economy. Due to the buffalo cows’ long life these aspects are also important to assess the improvement of genetic animal potential and to reach optimal productive performance. Currently this knowledge is critical since the Italian cattle population is decreasing whereas the national buffalo sector is expanding; this trend is partially depending on the reconversion of some dairy cattle’ farms into buffalo cows’ farms. The present investigation was undertaken to study non-genetic factors affecting reproductive parameters and milk production traits in a farm located in a not traditional area for buffalo farming.

  3. Study of thin-film silicon solar cells at irradiances above ten thousand suns

    International Nuclear Information System (INIS)

    We used a tightly focused Gaussian beam of a HeNe laser to study accelerated light-induced degradation (Staebler-Wronski effect) and high photocarrier generation rates in amorphous and microcrystalline silicon thin-film solar cells, at up to13 MW/m2 irradiance. For the experiments, the spot radius was varied from a minimum of 8.6 ?m in the focus to around 1 mm away from the focus. According to COMSOL'' (registered) simulations, even at these high power densities heat diffusion into a glass substrate aided by spreading conduction via the Ag back-contact restricts the temperature rise to less than 14 K. Short-circuit current can be measured directly over a range of irradiances, and the J-V characteristic may be estimated by taking into account shunting by the inactive part of the cell.

    Abstract It has long been held that schizophrenia and other psychotic disorders have a predominately poor course and outcome. We have synthesized information on mortality, clinical and social outcomes from the ÆSOP-10 multicenter study, a 10-year follow-up of a large epidemiologically characterized cohort of 557 people with first-episode psychosis. Symptomatic remission and recovery were more common than previously believed. Distinguishing between symptom and social recovery is important given the disparity between these; even when symptomatic recovery occurs social inclusion may remain elusive. Multiple factors were associated with an increased risk of mortality, but unnatural death was reduced by 90% when there was full family involvement at first contact compared with those without family involvement. These results suggest that researchers, clinicians and those affected by psychosis should countenance a much more optimistic view of symptomatic outcome than was assumed when these conditions were first described.

    Full Text Available Background / Objective : To determine the relative frequency of renal tumours with respect to age, sex and clinical presentation. Method : A retrospective review of histologic reports and clinical notes. Nephrectomy and renal specimens from autopsy were routinely processed and stained with hematoxylin and Eosin (H& E stain. The completed slides were viewed under the light microscope for the diagnosis of the tumours. Results : Thirty nine specimens accounting for 0.5% of the total tumours satisfied the criteria for the study. Thirty seven tumours (94.9% were malignant while 2(5.1% were benign. The youngest was an 8 months old female while the oldest was a 65 year old female. A total of 24(61.5% tumours occurred in males while 15(38.5% in females giving a sex ratio of 1.6:1. Nephroblastoma (64.1% was the commonest malignancy and majority occurred in children while renal cell carcinoma was the most common adult renal tumour. Haematuria was the most frequent clinical presentation. Conclusion :Renal tumours are rare in this environment but they may pose a significant morbidity and mortality. Though some present with severe clinical symptoms others may go unnoticed.

    2012-01-01

    BACKGROUND: Apathy is a common symptom in first episode psychosis (FEP), and is associated with poor functioning. Prevalence and correlates of apathy 10 years after the first psychotic episode remain unexplored. OBJECTIVE: The aims of the study were twofold: 1) to examine prevalence and predictors of apathy at 10 years, and 2) to examine the relationship between apathy at 10 years and concurrent symptoms, functioning and outcome, including subjective quality of life. METHODS: Three-hundred-and-one patients with FEP were included at baseline, 186 participated in the 10 year follow-up. Of these, 178 patients completed the Apathy Evaluation Scale (AES-S-Apathy). Patients were classified as having apathy (AES-S-Apathy?27) or not. The relationship between apathy and baseline variables (Demographics, Diagnosis, Duration of Untreated Psychosis), measures of symptomatology (Positive and Negative Syndrome Scale, Calgary Depression Scale for Schizophrenia), functioning (Global Assessment of Functioning Scale, Strauss Carpenter Level of Functioning Scale) and subjective quality of life (Lehman's Quality of Life Interview) were estimated through correlation analyses and blockwise multiple hierarchical regression analysis. RESULTS: Nearly 30% of patients met the threshold for being apathetic at follow-up. No baseline variables predicted apathy significantly at 10 years. Apathy was found to contribute independently to functioning and subjective quality of life, even when controlling for other significant correlates. CONCLUSIONS: Apathy is a common symptom in a FEP cohort 10 years after illness debut, and its presence relates to impaired functioning and poorer subjective quality of life.

    False aneurysm degeneration is a known complication of patch aortoplasty for coarctation of the aortic isthmus. Open surgical treatment consists of prosthetic graft repair of the involved aorta, often requires circulatory arrest to achieve a safe proximal aortic control and perform proximal anastomosis, and finally is associated with substantial perioperative morbidity. Endografting of the diseased aorta is a valuable alternative to open repair, when feasible, with good short and long term results. We now report one more case of false aneurysm ten years after Dacron patch aortoplasty for isthmic coarctation in a 26-year-old woman, successfully treated by endovascular repair via the left common iliac artery, and a complete exclusion of the aneurysm at two year follow-up.

  17. Leukemia in women following radiotherapy for cervical cancer: ten-year follow-up of an international study

    International Nuclear Information System (INIS)

    An international collaborative study, with 69 references, of 31,219 women treated for cervical cancer from 30 radiotherapy centers in nine countries was conducted. Patients were followed clinically and with blood studies between 1960 and 1970, and 148,000 woman-years (WY) were accumulated. Among 28,490 women treated with either intercavitary radium, external radiation, or both, 134,000 WY were accumulated and 13 cases of leukemia were observed. On the basis of general population rates, 15.5 cases were expected. A twofold risk could thus be excluded, but a 1.4-fold risk remained possible. In absolute terms, risks larger than 0.1 leukemia cases per 106 WY-rad could be excluded. Among 2,729 cervical cancer patients not irradiated but similarly evaluated, 14,000 WY were accumulated and 2 cases of leukemia were observed as compared with 1.0 expected. In the interval 4-8 years after exposure, the period in which any leukemogenic effect might be most apparent, 7 cases of leukemia were observed among exposed patients as compared with 5.4 expected. The absence of an increased leukemia risk suggested that the radiation regimens used to treat cervical cancer are not so effective in inducing leukemia as are other radiation exposures that have been studied

  18. BioFleet case studies

    International Nuclear Information System (INIS)

    These six case studies examined the use of different biodiesel blends as fuel supply sources for businesses in British Columbia (BC). In the first case study, 6 municipalities participated in a pilot program designed to compare the performance of biodiesel and diesel fuels. Each municipality operated 2 base vehicles running on conventional diesel along with 2 similar vehicles which used biodiesel. Real time emissions tests and analyses of the vehicles using biodiesel were also conducted by 2 of the participating municipalities. All municipalities participating in the study agreed to purchase significant volumes of biodiesel. The second case study described a pilot study conducted by the City of Vancouver's equipment services branch in 2004. As a result of the study, the city now has over 530 types of equipment that use biodiesel. The third case study described a program designed by TSI Terminals in Vancouver to assess the emission reduction impact of using biodiesel at its port facility. Six different pieces of equipment were used to confirm that biodiesel could be used throughout the terminal. Test results confirmed that biodiesel blends could be used to reduce emissions. Overall emissions were reduced by 30 per cent. The fourth case study described a waste renderer that used a fleet of 36 trucks to deliver raw products to its plants. The company made the decision to use only biodiesel for its entire fleet of trucks. Since July 2005, the company has logged over 1.7 mly 2005, the company has logged over 1.7 million km using biodiesel blends. The fifth case study described a salmon hatchery that switched from diesel to biodiesel in order to reduce emissions. The biodiesel blends are used to fuel the hatchery's 2 diesel generators. The hatchery has reduced emissions of greenhouse gases (GHGs) by an estimated 1800 tonnes annually. The sixth case study described how the Township of Langley has started using biodiesel for its entire fleet of of approximately 250 pieces of equipment. The township has not encountered any operational differences in their field operations since switching to biodiesel. 26 figs

    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.

    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

    Full Text Available Abstract Background In 1996, Mexico started to register cases of childhood cancer. Here, we describe the incidence of cancer in children, residing in ten Mexican jurisdictions, who were treated by the Instituto Mexicano del Seguro Social (IMSS. Methods New cases of childhood cancer, which were registered prospectively in nine principal Medical Centers of IMSS during the periods 1998–2000 (five jurisdictions and 1996–2002 (five jurisdictions, were analyzed. Personnel were specifically trained to register, capture, and encode information. For each of these jurisdictions, the frequency, average annual age-standardized incidence (AAS and average annual incidence per period by sex and, age, were calculated (rates per 1,000,000 children/years. Results In total 2,615 new cases of cancer were registered, with the male/female ratio generally >1, but in some tumors there were more cases in females (retinoblastoma, germ cells tumors. The principal groups of neoplasms in seven jurisdictions were leukemias, central nervous system tumors (CNS tumors, and lymphomas, and the combined frequency for these three groups was 62.6 to 77.2%. Most frequently found (five jurisdictions was the North American-European pattern (leukemias-CNS tumors-lymphomas. Eight jurisdictions had AAS within the range reported in the world literature. The highest incidence was found for children underless than five year of age. In eight jurisdictions, leukemia had high incidence (>50. The AAS of lymphomas was between 1.9 to 28.6. Chiapas and Guerrero had the highest AAS of CNS tumors (31.9 and 30.3, respectively. The frequency and incidence of neuroblastoma was low. Chiapas had the highest incidence of retinoblastoma (21.8. Germ-cell tumors had high incidence. Conclusion The North American-European pattern of cancers was the principal one found; the overall incidence was within the range reported worldwide. In general but particularly in two jurisdictions (Yucatán and Chiapas, it will be necessary to carry out studies concerning the causes of cancer in children. Due to the little that is known about the incidence of cancer in Mexican children, it will be necessary to develop a national program to establish a cancer registry for the whole of the country.

    2015-05-01

    The aim of this study was to evaluate the ten-year clinical and functional outcome of hip resurfacing and to compare it with that of cementless hip arthroplasty in patients under the age of 55 years. Between 1999 and 2002, 80 patients were enrolled into the study: 24 were randomised (11 to hip resurfacing, 13 to total hip arthroplasty), 18 refused hip resurfacing and chose cementless total hip arthroplasty with a 32 mm bearing, and 38 insisted on resurfacing. The mean follow-up for all patients was 12.1 years (10 to 14). Patients were assessed clinically and radiologically at one year, five years and ten years. Outcome measures included EuroQol EQ5D, Oxford, Harris hip, University of California Los Angeles and University College Hospital functional scores. No differences were seen between the two groups in the Oxford or Harris hip scores or in the quality of life scores. Despite a similar aspiration to activity pre-operatively, a higher proportion of patients with a hip resurfacing were running and involved in sport and heavy manual labour after ten years. We found significantly higher function scores in patients who had undergone hip resurfacing than in those with a cementless hip arthroplasty at ten years. This suggests a functional advantage for hip resurfacing. There were no other attendant problems. Cite this article: Bone Joint J 2015; 97-B:617-22. PMID:25922454

  7. A parathyroid scintigraphy case study

    International Nuclear Information System (INIS)

    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

    1991-01-01

    To increase the number of chemicals tested using the Zeste-White (UZ) somatic mutation assay, ten selected carcinogens (acetamide, acrylamide, benzo({alpha})pyrene, cyclophosphamide, diethylstilbestrol, 4-nitroquinoline N-oxide, propyleneimine, safrole, thiourea, and o-toluidine) have been evaluated in this assay. The results show that all the compounds tested produce significant increases in the eye spot frequency at, at least, one of the concentrations assayed, indicating that the Zeste-White assay appears to be highly sensitive to these carcinogenic compounds. That is in agreement with data previously reported by other authors.

    Full Text Available Background: The masculine mammal cancer is extremely infrequent, so many authors consider it as a truly clinical rareness. Objectives: To describe the clinical-pathological behaviour of the mammal cancer in men in the province of Cienfuegos. Method: A descriptive-retrospective study was carried out of all the cases of mammal cancer in men, submitted to surgery in the Universitary Hospital "Dr Gustavo Aldereguia Lima” of Cienfuegos, between January 1996 and December 2005. The variables were: age, affected mamma, topographic localization of the tumour, clinical stage in the moment of diagnosis, histological variant, type of biopsy used, surgical technique applied, and health area. Results: The mayority of cases was registered in the 61-70 age group (44.4%; and respecting benign tumors, it was found in the 31-40 age group with 9 cases (31.3%. An increase incidence was observed in the last seven years, as well as its detection in quite advanced stages. Conclusions: It is necessary to find mechanisms to establish ways of early detection of the mammal tumours in the province, for which it is essential, the clinical personnel preparation and the dispensarization of all the men presenting factors for the mammal tumour.

    2010-01-01

    Full Text Available Abstract Objectives Endometriosis has been believed to increase the risk of developing ovarian cancer, but recent data supporting this hypothesis are lacking. The aim of this study was to verify whether the incidence of endometriosis, ovarian cancer and the both increased during the last 10 years among women living in the Estrie region of Quebec. Methods We collected data of women diagnosed with endometriosis, ovarian cancer or both, between 1997 and 2006, from a population living in the Estrie region of Quebec. We performed this retrospective cross-sectional study from the CIRESSS (Centre Informatisé de Recherche Évaluative en Services et Soins de Santé system, the database of the CHUS (Centre Hospitalier Universitaire of Sherbrooke, Sherbrooke, Canada. Results Among the 2854 identified patients, 2521 had endometriosis, 292 patients had ovarian cancer and 41 patients had both ovarian cancer and endometriosis. We showed a constant increase in the number of ovarian cancer (OC between 1997 and 2006 (r2 = 0.557, P = 0.013, which is not the case for endometriosis (ENDO or endometriosis-associated ovarian cancer (EAOC. The mean age ± SD was 40.0 ± 9.9 and 53.9 ± 11.4 for patients having ENDO and OC, respectively. Mean age of women with EAOC was 48.3 ± 10.8, suggesting an early onset of ovarian cancer in women having endometriosis of about 5.5 years average, P = 0.003. Women with ENDO were at increased risk for developing OC (Rate Ratio [RR] = 1.6; 95% Confidence Interval [CI] = 1.12-2.09. Pathological analyses showed the predominance of endometrioid type (24.4% and clear-cell type (21.9% types in EAOC compared to OC, P = 0.0070 and 0.0029, respectively. However, the serous type is the most widespread in OC (44.5% in comparison to EAOC (19.51%, P = 0.0023. Conclusion Our findings highlight that the number of cases of ovarian cancer is constantly increasing in the last ten years and that endometriosis represents a serious risk factor which accelerates its apparition by about 5.5 years.

  18. Probabilistic consequence study of residual radiological effects from a hypothetical ten-ton inadvertent nuclear yield. Weapons Safety Program

    International Nuclear Information System (INIS)

    In this paper we study the potential radiological consequences of a strategic bomber accident, in which one of the assumed on-board nuclear weapons explodes with an arbitrarily chosen 10-ton nuclear yield. The frequency of such an occurrence is infinitesimal. The safety design features in today s nuclear weapons' systems essentially forbid its occurrence. We have a chosen a military base which has the feature of being a representative combination of urban and rural populations. The assumed ''crash site'' is near the northwest comer of the military base, close to civilian housing located just across the street from the base. A worst case wind would be from the ESE (east south east). This would cause fission debris to be dispersed toward the largest population centers and, thus, would lead to the largest Pu ''collective'' doses (i.e., a dose integrated over time and summed over individuals). Also, if an ESE wind were blowing at accident time, some people in nearby housing could receive lethal gamma-ray doses from fallout before evacuation could occur. It is assumed only one weapon undergoes nuclear yield; the other on-board weapons would HE detonate and the Pu would be aerosolized and lofted. We assume an activity-size distribution and lofting similar to those used to predict fallout measured at NTS. The main thrust of our study is to provide estimates of probabilistic radiological risks to the population local to a strategic bomber crash site. The studied radiological consequences are: cloud-passage doses from Pu inhalation; doses from groundshine due to gamma-producing radionuclides; and areal contamination from Pu and the long-lived fission products Cs-137 and Sr-90

  19. Five misunderstandings about Case-study Research

    DEFF Research Database (Denmark)

    Flyvbjerg, Bent

    2004-01-01

    This article examines five common misunderstandings about case-study research: (1) Theoretical knowledge is more valuable than practical knowledge; (2) One cannot generalize from a single case, therefore the single case study cannot contribute to scientific development; (3) The case study is most useful for generating hypotheses, while other methods aremore suitable for hypotheses testing and theory building; (4) The case study contains a bias toward verification; and (5) It is often difficult to summarize specific case studies. The article explains and corrects these misunderstandings one by one and concludes with the Kuhnian insight that a scientific discipline without a large number of thoroughly executed case studies is a discipline without systematic production of exemplars, and that a discipline without  exemplars is an ineffective one. Social science may be strengthened by the execution of more good case studies.

    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.

  6. Ten Problems in Experimental Mathematics

    Energy Technology Data Exchange (ETDEWEB)

    Bailey, David H.; Borwein, Jonathan M.; Kapoor, Vishaal; Weisstein, Eric

    2004-09-30

    This article was stimulated by the recent SIAM ''100 DigitChallenge'' of Nick Trefethen, beautifully described in a recent book. Indeed, these ten numeric challenge problems are also listed in a recent book by two of present authors, where they are followed by the ten symbolic/numeric challenge problems that are discussed in this article. Our intent was to present ten problems that are characteristic of the sorts of problems that commonly arise in ''experimental mathematics''. The challenge in each case is to obtain a high precision numeric evaluation of the quantity, and then, if possible, to obtain a symbolic answer, ideally one with proof. Our goal in this article is to provide solutions to these ten problems, and in the process present a concise account of how one combines symbolic and numeric computation, which may be termed ''hybrid computation'', in the process of mathematical discovery.

    1960-06-01

    Full Text Available O autor, revendo o conceito atual da etiopatogenia das mieloses funiculares, conclui que, na determinação do processo desmielinizante, além da carência de vitamina B12 e da acloridria gástrica, participam outros fatores, carenciais e/ou alérgicos. Baseado no estudo de 110 casos com lesões gástricas [...] constitucionais (100 casos) ou adquiridas (10 casos), o autor discute o problema do diagnóstico. São consideradas as síndromes periférica, funicular dorsal, "piramidal" e encefálica. É ressaltada a importância do exame da sensibilidade vibratória, particularmente por método quantitativo, que revelou, em elevada percentagem dos casos, distúrbios da palestesia também nas mãos. Entre os exames complementares, é salientado o valor do hemograma, do mielograma, da dosagem da acidez gástrica, da determinação da absorção da vitamina B12 radioativa; são também consideradas as alterações electrencefalográficas e do liqüido cefalorraqueano. Os resultados terapêuticos em 44 casos são avaliados através do estudo semiquantitativo da sintomatologia neurológica. Embora a vitamina B12 tenha proporcionado maiores índices de melhora, os demais medicamentos (extrato hepático, ácido fólico e adrenocorticotropina) também influenciaram favoravelmente o quadro neurológico. Em vista da pequena representação numérica da casuística nos grupos correspondentes aos quatro esquemas terapêuticos, o autor não emite conclusão definitiva. Salienta, porém, que êsses resultados demonstram a necessidade de prosseguir nos estudos sôbre a etiopatogenia das mieloses funiculares, no sentido de esclarecer as numerosas incógnitas que ainda perduram. Abstract in english After a review on the present concept of the etiopathogenesis of funicular myelosis (subacute combined degeneration of the spinal cord) the author states the conclusion that in the causation of the demyelinating process, besides the lack of vitamin B]2 and gastric achlorhydria, other deficiency or a [...] llergic factors take part. Based on the study of 110 cases with constitutional (100 cases) or acquired (10 cases) gastric lesions, the author discusses the problem of the diagnosis. Peripheral, dorsal funicular, "pyramidal", and encephalic syndromes are considered. The importance of the examination of the vibration sense, particularly by quantitative methods, is emphasized; in a great percentage of cases, disturbances of this sensation were also disclosed in the upper limbs. Among the laboratory findings, the value of blood count, bone-marrow smear, gastric acidity analysis, and the study of absorption of radioactive vitamin B12 is stressed. Changes in the electroencephalogram and cerebrospinal fluid are also considered. Therapeutic results in 44 cases are estimated by the semi-quantitative study of the neurological signs. Although vitamin B12 displayed higher degree of improvement, the other drugs (liver extract, folic acid and adreno-corticotropin) have also influenced favorably the neurological manifestations. Owing to the low numerical representation of cases in the groups corresponding to the four schemes of treatment, the author does not state a definite conclusion. But he emphasizes that these results demonstrate the need of further studies on the etiopathogenesis of funicular myelosis, in an attempt to settle the several questions still unsolved.

  14. The case for case studies: Optimising the use of communication cases

    Directory of Open Access Journals (Sweden)

    Tony Jaques

    2009-01-01

    Full Text Available Case studies are widely used by communication and public relations practitioners and educators. Yet, despite their extensive use, the question should be asked whether public relations case studies are applied in the best possible way. Many tertiary education institutions are moving away from case study analysis as a discrete subject and instead adopting a ‘case study approach’ across the communication curriculum. This paper explores the merits of different styles of the case method and the reference materials available, and concludes that formalised analysis of case studies is essential to fully optimise their application.

It also explores on the advantages and disadvantages of case study as a research method.

  17. The 'fine structure' of nutrient dynamics in rivers: ten years of study using high-frequency monitoring

    A complete appraisal of material fluxes in flowing waters is really only possibly with high time resolution data synchronous with measurements of discharge. Defined by Kirchner et al. (2004; Hydrological Processes, 18/7) as the high-frequency wave of the future and with regard to disentangling signal noise from process pattern, this challenge has been met in terms of nutrient flux monitoring by automated bankside analysis. In Ireland over a ten-year period, time-series nutrient data collected on a sub-hourly basis in rivers have been used to distinguish fluxes from different catchment sources and pathways and to provide more certain temporal pictures of flux for the comparative definition of catchment nutrient dynamics. In catchments where nutrient fluxes are particularly high and exhibit a mix of extreme diffuse and point source influences, high time resolution data analysis indicates that there are no satisfactory statistical proxies for seasonal or annual flux predictions that use coarse datasets. Or at least exposes the limits of statistical approaches to catchment scale and hydrological response. This has profound implications for catchment monitoring programmes that rely on modelled relationships. However, using high resolution monitoring for long term assessments of catchment mitigation measures comes with further challenges. Sustaining continuous wet chemistry analysis at river stations is resource intensive in terms of capital, maintenance and quality assurance. Furthermore, big data capture requires investment in data management systems and analysis. These two institutional challenges are magnified when considering the extended time period required to identify the influences of land-based nutrient control measures on water based systems. Separating the 'climate signal' from the 'source signal' in river nutrient flux data is a major analysis challenge; more so when tackled with anything but higher resolution data. Nevertheless, there is scope to lower costs in bankside analysis through technology development, and the scientific advantages of these data are clear and exciting. When integrating its use with policy appraisal, it must be made clear that the advances in river process understanding from high resolution monitoring data capture come as a package with the ability to make more informed decisions through an investment in better information.

  18. Geothermal Exploration Case Studies on OpenEI (Presentation)

    2014-03-01

    The U.S. Geological Survey (USGS) resource assessment (Williams et al., 2008) outlined a mean 30 GWe of undiscovered hydrothermal resource in the western United States. One goal of the U.S. Department of Energy's (DOE) Geothermal Technology Office (GTO) is to accelerate the development of this undiscovered resource. DOE has focused efforts on helping industry identify hidden geothermal resources to increase geothermal capacity in the near term. Increased exploration activity will produce more prospects, more discoveries, and more readily developable resources. Detailed exploration case studies akin to those found in oil and gas (e.g. Beaumont and Foster, 1990-1992) will give developers central location for information gives models for identifying new geothermal areas, and guide efficient exploration and development of these areas. To support this effort, the National Renewable Energy Laboratory (NREL) has been working with GTO to develop a template for geothermal case studies on the Geothermal Gateway on OpenEI. In 2012, the template was developed and tested with two case studies: Raft River Geothermal Area (http://en.openei.org/wiki/Raft_River_Geothermal_Area) and Coso Geothermal Area (http://en.openei.org/wiki/Coso_Geothermal_Area). In 2013, ten additional case studies were completed, and Semantic MediaWiki features were developed to allow for more data and the direct citations of these data. These case studies are now in the process of external peer review. In 2014, NREL is working with universities and industry partners to populate additional case studies on OpenEI. The goal is to provide a large enough data set to start conducting analyses of exploration programs to identify correlations between successful exploration plans for areas with similar geologic occurrence models.

    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.

    Full Text Available Abstract Background Disaster experiences have been associated with higher prevalence rates of (mental health problems. The objective of this study was to examine the independent relation between a series of single disaster experiences versus the independent predictive value of a accumulation of disaster experiences, i.e. a sum score of experiences and symptoms of distress and post-traumatic stress disorder (PTSD. Methods Survivors of a fireworks disaster participated in a longitudinal study and completed a questionnaire three weeks (wave 1, eighteen months (wave 2 and four years post-disaster (wave 3. Ten years post-disaster (wave 4 the respondents consisted of native Dutch survivors only. Main outcome measures were general distress and symptoms of PTSD. Results Degree of disaster exposure (sum score and some disaster-related experiences (such as house destroyed, injured, confusion were related to distress at waves 2 and 3. This relation was mediated by distress at an earlier point in time. None of the individual disaster-related experiences was independently related to symptoms of distress. The association between the degree of disaster exposure and symptoms of PTSD at waves 2 and 3 was still statistically significant after controlling for symptoms of distress and PTSD at earlier point in time. The variable ‘house destroyed’ was the only factor that was independently related to symptoms of PTSD at wave 2. Ten years after the disaster, disaster exposure was mediated by symptoms of PTSD at waves 2 and 3. Disaster exposure was not independently related to symptoms of PTSD ten years post-disaster. Conclusions Until 4 years after the disaster, degree of exposure (a sum score was a risk factor for PTSD symptoms while none of the individual disaster experiences could be identified as an independent risk factor. Ten years post-disaster, disaster exposure was no longer an independent risk factor for symptoms of PTSD. Since symptoms of PTSD and distress at earlier waves perpetuate the symptoms at later waves, health care workers should aim their resources at those who still have symptoms after one and a half year post-disaster, to prevent health problems at medium and long-term.

    The research presented in this dissertation covers three separate topics of conservation as defined by the National Science Foundation: 1) Materials Stabilization, Strengthening, Monitoring, and Repair; 2. Understanding Material Degradation and Aging; and 3) Materials and Structural Characterization of Cultural Heritage Objects (the 'technical study'). The first topic is addressed through a study to assess the consolidant tetraethoxysilane for the stabilization of alum treated wood. Falling under materials degradation studies is a study published in American Museum Novitates to understand how environmental conditions affect the aging of fossil resins from five different deposits. Two separate studies are included in technical study of cultural heritage objects which comprises the third research area of materials characterization. The first is a survey of red dyes used in Chinese paintings from the Ming Dynasty to the Early Republic (1364-1911). The second is a study of the pigments, dyes and binders used in Hawaiian barkcloth (kapa) from the 19th century.

    1999-12-01

    Twenty-two children with spinal paraplegia were entered into a prospective randomised study to assess the efficacy of two reciprocating orthoses and to identify any prognostic factors that might affect continuing use of the devices. Thirteen received a hip guidance orthosis (HGO) and nine a reciprocating gait orthosis (RGO). They were followed for a mean of ten years. At one year follow-up there were three statistically significant differences between the two groups at the 5% level: repairs were commoner in the RGO group, the RGO group improved in their ability to walk over difficult outdoor surfaces and the HGO group improved more in their ability to rise from a sitting to standing position. At one year follow-up there was a positive parental and child's view of the benefits of the orthoses, but by ten years only 24% of the patients were still using the orthoses. We were not able to show any definite advantage of one device over the other or any statistically significant prognostic factors for walking in the longer term with a reciprocating orthosis. We question whether or not the routine provision of these types of orthosis is justifiable when it appears that, in the longer term, the patients we studied preferred wheelchair mobility.

    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.

  14. Waves and turbulences studies in plasmas: ten years of research on quiescent plasmas at the Brazilian Space Research National Institute

    International Nuclear Information System (INIS)

    Quiescent plasmas generated by thermionic discharges and surface confined by multipole magnetic fields have been used in basic plasma research since 1973. The first machine was developed at UCLA (USA) to produce an uniform plasma for beam and waves studies in large cross section plasmas. A double quiescent plasma machine was constructed at the plasma laboratory of INPE in 1981, it began its operation producing linear ion-acoustic waves in an Argon plasma. Later on non linear ion acoustic waves and solitons were studied in plasma containing several species of negative and positive ions. The anomalous particle transport across multipole magnetic fields were also investigated. An anomalous resistivity associated with an ion acoustic turbulence is responsible for the formation of a small amplitude double-layer. The existence of a bootstrap mechanism is shown experimentally. Today, the main interest is toward the generation of Langmuir waves in non uniform plasmas. An experimental study on Langmuir wave generation using a grid system is been carried on. A magnetized quiescent plasma device for studies of whistle wave generation is been constructed. This machine will make possible future studies on several wave modes of magnetized plasmas.

    Full Text Available The paper presents a case of leishmaniasis in a 2.5-month-old dog imported from France. The clinical examination established a generally poor state of health, expressed cachexia, atrophy of the temporal musculature, weakness of movement, as well as abnormally long and brittle nails. There was also hyperkeratosis of the nose tip and paws. A histological examination of biopsy sections of the altered skin parts showed inflammatory changes in the area of the dermis, together with infiltration of macrophages and a smaller number of lymphocytes, plasmocytes and neutrophil granulocytes in the area around the sebaceous glands and hair follicles. The determined changes correspond to superficial dermatitis. Edema followed by partial degeneration of connective-tissue fibers is observed in connective tissue. A smaller number of intracellular parasitic forms was established in mononuclear cells. A smaller number of oval amastigotes with round dark red nucleis were observed in sections stained using the Gimza method in the cytoplasm of macrophages located in the dermis, but also extracellularly. It was concluded that the dog was diseased with leishmaniasis on the grounds of the clinical picture and the microscopic findings.

    One hundred Danes with oral cancer who were collected consecutively from 1986 to 1991 were evaluated retrospectively. The study included subjective and objective observations in 56% men and in 44% women. M:F ratio was 1.2:1. Fifty percent of the patients were non-smokers. Nine percent were women who did not drink alcohol. Ten percent of the patients were between 40 and 49 years of age, 20% between 50 and 59 years, 35% were between 60 and 69 years and 20% between 70 and 79 years of age. This may reflect a tradition of early drinking and smoking. Doctor's delay was the cause of delayed referral in 14% of the cases while 72% of the patients were the cause themselves for the delayed referral.

  4. Ten-year absolute risk of osteoporotic fractures according to BMD T score at menopause : the Danish Osteoporosis Prevention Study

    Abrahamsen, Bo; Vestergaard, Peter

    2006-01-01

    In the non-HRT arms of the DOPS study, 10-year fracture risk was higher at each level of T score than predicted by the Kanis algorithm. Under-reporting of fractures in registers and inclusion of HRT users are probable explanations for inappropriately low fracture risk estimates for younger women. INTRODUCTION: International recommendations highlight the importance of absolute fracture risk in establishing intervention thresholds. The available estimates of long-term risk have been derived by combining relative risks from meta-analyses with U.S. normative BMD data and Swedish fracture incidence records. We validated the 2001 Kanis risk algorithm using incident fractures observed in untreated women in the first 10 years of the Danish Osteoporosis Prevention Study (DOPS). Comparisons were also made with the relative risks derived from a recent meta-analysis of 12 cohort studies. MATERIALS AND METHODS: We analyzed DXA of the spine and hip from 872 women who were enrolled in the non-hormone replacement therapy (HRT) arms of the study and had not received HRT, bisphosphonates, or raloxifene. We collected verified reports of fractures at each visit. We focused on fractures of the hip, spine, shoulder, and forearm to provide risks comparable with the Kanis algorithm. Accordingly, asymptomatic radiographic vertebral fractures were not included. RESULTS: Seventy-eight women (9%) sustained relevant fractures. The risk of fracture increased by 1.32 (95% CI, 1.02; 1.70) for each unit decrease in femoral neck T score and by 1.30 (95% CI, 1.06; 1.58) for each unit decrease in lumbar spine T score at baseline. Absolute fracture risk was higher than expected from the Kanis algorithm at all T score levels. The difference was greatest for participants in the higher range of T scores. At T = -1, the observed risk was 10.9% as opposed to an expected risk of 5.7%. Relative risk gradients were similar to those of the recent meta-analysis. CONCLUSIONS: In healthy women, examined in the first year or two after menopause, 10-year fracturerisk was higher at each level of BMD T score than expected from the model by Kanis et al. Inclusion of HRT users in the cohorts used may have led to higher BMD values and lower absolute fracture risk in the Kanis model. These longitudinal data can be used directly in estimating absolute fracture risk in untreated north European women from BMD at menopause.

    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.

    Objective Medical personnel are at risk of musculoskeletal disorders but little is known whether the risk of musculoskeletal disorders were different among various medical professions. Therefore, this study compared the risk of musculoskeletal disorders among personnel of 10 different medical professions in Taiwan using a nationwide health claims database. Methods Data from the 2000–2010 Taiwan National Health Insurance Research Database were used to identify personnel of 10 different medical professions. Diagnoses based on the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) were used to identify eight different musculoskeletal disorders that occurred after the license issuance date. Cox proportional hazards model was used to compare the risk of eight musculoskeletal disorders among the 10 different medical professions using dentists as the reference category. Results A total of 7,820 medical personnel were included in the analysis. Using dentists as the reference category, physical therapists showed a significantly higher risk of all eight musculoskeletal disorders (ranging from 1.59 [p = 0.032] in sprains and strains of other and unspecified parts of back to 2.93 [p disorders). Conclusions Compared with dentists, a profession that already known to suffer from high rates of work-related musculoskeletal disorders, physical therapists, registered nurses, and doctors of Chinese medicine showed an even higher risk of musculoskeletal disorders.

    Jan Skov Jensen

    2010-02-01

    Full Text Available Our study evaluates the long-term effect of microalbuminuria on mortality among patients with acute myocardial infarction. We followed 151 patients from 1996 to 2007 to investigate if microalbuminuria is a risk factor in coronary heart disease. All patients admitted with acute myocardial infarction in 1996 were included. At baseline, we recorded urinary albumin/creatinine concentration ratio, body mass index, blood pressure, left ventricle ejection fraction by echocardiography, smoking status, medication, diabetes, age, and gender. Deaths were traced in 2007 by means of the Danish Personal Identification Register. Microalbuminuria, defined as a urinary albumin/creatinine concentration ratio above 0.65 mg/mmoL, occurred in 50% of the patients and was associated with increased all-cause mortality. Thus, 68% of the patients with microalbuminuria versus 48% of the patients without microalbuminuria had died during the 10 years of follow-up (P=0.04. The crude hazard ratio for death associated with microalbuminuria was 1.78 (CI: 1.18-2.68 (P=0.006, whereas the gender- and age-adjusted hazard ratio was 1.71 (CI: 1.03-2.83 (P=0.04. We concluded that microalbuminuria in hospitalized patients with acute myocardial infarction is prognostic for increased long-term mortality. We recommend measurement of microalbuminuria to be included as a baseline risk factor in patients with acute myocardial infarction and in future trials in patients with cor-onary heart disease.

    As a proportion of all deaths in India, cardiovascular disease (CVD) will be the largest cause of disability and death, by the year 2020. At the present stage of India's health transition, an estimated 53% of deaths and 44% of disability-adjusted life-years lost are contributed to chronic diseases. India also has the largest number of people with diabetes in the world, with an estimated 19.3 million in 1995 and projected 57.2 million in 2025. The prevalence of hypertension has been reported to range from 20 to 40% in urban adults and 12-17% among rural adults. The number of people with hypertension is expected to increase from 118.2 million in 2000 to 213.5 million in 2025, with nearly equal numbers of men and women. Over the coming decade, until 2015, CVD and diabetes will contribute to a cumulative loss of USD237 billion for the Indian economy. Much of this enormous burden is already evident in urban as well as semi-urban and slum dwellings across India, where increasing lifespan and rapid acquisition of adverse lifestyles related to the demographic transition contribute to the rising prevalence of CVDs and its risk factors such as obesity, hypertension, and type 2 diabetes. The underlying determinants are sociobehavioral factors such as smoking, physical inactivity, improper diet and stress. The changes in diet and physical activity have resulted largely from the epidemiological transition that is underway in most low income countries including India. The main driving forces of these epidemiological shifts are the globalized world, rapid and uneven urbanization, demographic shifts and inter- and intra-country migrations--all of which result in alterations in dietary practices and decreased physical activity. While these changes are global, India has several unique features. The transitions in India are uneven with several states in India still battling the ill effects of undernutrition and infectious diseases, while in other states with better indices of development, chronic diseases including diabetes are emerging as a major area of concern. Regional and urban-rural differences in the occurrence of CVD are the hallmark. All these differences result in a differing prevalence of CVD and its risk factors. Therefore while studying nutrition and physical activity shifts in India, the marked heterogeneity and secular changes in dietary and physical activity practices should be taken into account. This principle should also apply to strategies, policies and nutrition and physical activity guidelines so that they take the regional differences into account. PMID:19346764

    Full Text Available Human papillomavirus (HPV is one of the most common causes of sexually transmitted diseases in both men and women around the world. It has been suggested that the heparan sulfate constitute the main receptor recognized by HPV, however its role during the interactions with other HPV is not very clear. BC, DE, EF, FG, and HI are the five loops displayed on the surface of the pentamer which can interact with heparin as an analogue for heparan sulfate. In this study, the L1 late protein of ten high risks HPV (HR HPV L1 corresponding to the types 31/33/35/39/45/51/52/56/58/59 were analyzed using in silico methods by looking for insights related to HR HPV L1-loops and heparin interactions. The five loop regions (BC, DE, EF, FG and HI of the ten HR HPV L1 interact with heparin, where the interaction established between the BC-loop and heparin was found to be present in all the HR HPV L1 analyzed in this study as well as those reported in the scientist literature. Moreover it was found that lysine residues are involves in most of interactions and that the chargecharge and polar interactions are stabilizing the HR HPV L1-heparin interaction. The results obtained in this work with all the in silico methods; suggest that the heparin-binding site in the loops for all the HR HPV plays an important role during HR HPV infections, where BC-loop constitute the most required structure during the HR HPV L1-heparin interactions. The charge-charge and polar interactions are the main forces stabilizing the HR HPV L1-heparin.

    OpenAIRE

    Hayes, Rj; Marsh, K.; Snow, Rw

    1992-01-01

    The majority of children infected with Plasmodium falciparum in areas of stable endemicity do not develop severe, life-threatening disease. It is important to identify risk factors for the minority who do. Case-control studies in which children with severe disease are compared with children with non-severe disease and with community controls, avoid some of the ethical and logistical problems inherent in such an undertaking. This paper discusses methodological aspects of case-control studies o...

    2006-01-01

    Storytelling as a formal educational device arguably entered the didactic scene about 100 years ago with case study teaching at Harvard (Herreid 1994). There in the law and business schools, instructors and students analyzed realistic stories as exemplars of good and bad practice. Today, however, storytelling does not have to be limited to the traditional discussion formula advocated in these schools. This chapter describes various types of case study methods, reviews their virtues and weaknesses, and discusses the impact of case-based instruction in science education.

  4. Chernobyl - ten years after

    International Nuclear Information System (INIS)

    This folder contains ten brief factsheets which aim to give a balanced presentation of the facts relating to the reactor accident at the Chernobyl power station ten years after the event. Details of the incident are given and its aftermath, in particular as it has affected the lives and health of people living in the immediate vicinity, is considered. Since records of the health of people in the region before the accident were very poor, it is extremely difficult to make definitive statements about the health effects of the accident. It is clear, however, that there has been a marked increase in the incidence of thyroid cancer especially among children in Belarus. Although curable this has given rise to deaths owing to poor health care. It is likely that deaths due to other cancers will occur in the longer term. Though estimates vary, they are in the region of 10-25,000 world wide over the next 70 years. Comparisons with the numbers of deaths from other large-scale non-nuclear industrial disasters are provided which put the Chernobyl incident in context and experts who refute the wilder claims made in the media are quoted. The status of the plant today and the international effort to improve the safety of the 15 original RMBK commercial reactors still operating in the former USSR are described. (Author)

  5. Teaching Business Demography Using Case Studies.

    Swanson, David A; Morrison, Peter A

    2010-02-01

    Many faculty members consider using case studies but not all end up using them. We provide a brief review of what cases are intended to do and identify three ways in which they can be used. We then use an example to illustrate how we have used the case study method in teaching business demography. Among other benefits, we note that the case studies method not only encourages the acquisition of skills by students, but can be used to promote "deep structure learning," an approach naturally accommodates other features associated with the case studies method-the development of critical thinking skills, the use of real world problems, the emphasis of concepts over mechanics, writing and presentation skills, active cooperative learning and the "worthwhileness" of a course. As noted by others, we understand the limitations of the case study method. However, given its strengths, we believe it has a place in the instructional toolbox for courses in business demography. The fact that courses we teach is a testament to our perceived efficacy of this tool. PMID:20190858

    2014-01-01

    Background: Femoral fracture rates of up to 30% have been reported following lengthening procedures using fixators. “Lengthening then rodding” uses one or two titanium elastic nails (TENs) for prophylactic intramedullary nailing to reduce this complication. The aim of the study was to decide if usage of only one TEN is safe or has it a higher risk of getting a fracture? And we asked if there is a difference between patients with monolateral or bilateral lengthening procedures according to the...

  9. Ten Questions about Emergence

    CERN Document Server

    Fromm, J

    2005-01-01

    Self-Organization is of growing importance for large distributed computing systems. In these systems, a central control and manual management is exceedingly difficult or even impossible. Emergence is widely recognized as the core principle behind self-organization. Therefore the idea to use both principles to control and organize large-scale distributed systems is very attractive and not so far off. Yet there are many open questions about emergence and self-organization, ranging from a clear definition and scientific understanding to the possible applications in engineering and technology, including the limitations of both concepts. Self-organizing systems with emergent properties are highly desirable, but also very challenging. We pose ten central questions about emergence, give preliminary answers, and identify four basic limits of self-organization: a size limit, a place limit, a complexity limit and finally a combinatorial limit.

    2011-06-01

    Full Text Available Abstract Background There are several treatment approaches for pineal region meningiomas, such as Poppen's approach, Krause's approach and combinations of the two approaches. We present our experience with the use of 3D-computed tomography angiography for planning the surgical removal of pineal region meningiomas using a suboccipital transtentorial approach (Poppen's approach and evaluate the role of Poppen's approach. Methods During the period from January 2005 to June 2010, ten patients presented to us with pineal region meningioma. MRI was routinely used to define the tumor size, position, and its relevant complications while 3D-CTA was applied to define the blood supply of the tumor and the venous complex (VC shift before operations. Most of the meningiomas had developed at both sides of the tentorial plane and extended laterally with typical characteristics of a pineal region tumor. Results All tumors were completely removed surgically without any injury to the VC. Postoperative intracranial infection occurred in one case who recovered after antibiotics were given. Postoperative intraventricular hemorrhage and pneumocephalus were found in one case, but fully recovered after conservative treatment. In the nine cases of concurrent hydrocephalus, this was gradually relieved in eight patients and the single case that became aggravated was successfully treated with ventriculoperitoneal shunt. Moreover, the follow-up MRI examinations did not indicate any recurrence of the meningiomas. Conclusion We found that the use of Poppen's approach is strongly supported for the successful removal of pineal region meningiomas without serious complications.

  14. External radiotherapy prior to thyroid cancer: A case-control study

    International Nuclear Information System (INIS)

    The aim of this investigation was to study previous radiotherapy of malignant diseases as a risk factor for thyroid cancer. By using the Swedish Cancer Registry all cases of thyroid cancer with another malignant disease at least one year previously and living within the catchment area of the hospital were traced. During 1959-1989 a total of 1056 cases of thyroid cancer were identified. Of these, 37 had had another previous malignant disease and they constituted the cases in this study. As controls four persons with at least two malignant diseases, thyroid cancer excluded, were selected for each case from the same cancer registry. Ten (27.0%) of the 37 patients with thyroid cancer as a second tumor had earlier been irradiated with the treatment dose including the thyroid gland as compared with 34 (24.5%) of the 139 control patients. Eight of the ten cases with previous irradiation of the thyroid gland had papillary cancer. The median latency was 13 years. The estimated radiation dose in the thyroid varied between 3 and 40 Gy. External radiotherapy gave a crude odds ratio of 1.1 with 95% confidence interval = 0.5-2.8 for thyroid cancer. The weighted odds ratio was calculated to 2.3 with confidence interval = 0.5-8.9. This case-control study gave a nonsignificantly increased odds ratio for thyroid cancer in patients with external radiotherapy including the thyroid gland. 26 refs., 4 tabs

    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.

  16. Chrono-pharmacological study of once daily curative dose of a low molecular weight heparin (200 IU antiXa/kg of Dalteparin) in ten healthy volunteers.

    1995-08-01

    Low molecular weight heparin (LMWH) is currently prescribed for the treatment of deep vein thrombosis at the dose of 100 IU antiXa/kg twice daily or at a dose of 175 IU antiXa/kg once daily with a similar efficacy. We decided to study the chrono-pharmacology of curative dose of LMWH once daily administrated according to the one previously described with unfractionated heparin (UFH). Ten healthy volunteers participated in an open three-period crossover study according to three 24 h cycles, separated by a wash-out interval lasting 7 days: one control cycle without injection, two cycles with subcutaneous injection of 200 IU antiXa/kg of Dalteparin (Fragmin) at 8 a.m. or at 8 p.m. Parameters of heparin activity were analysed as maximal values and area under the curve. Activated partial thromboplastin time (APTT), thrombin time (TT), prothrombin time (PT) and tissue factor pathway inhibitor (TFPI) were higher after 8 p.m. injection than after 8 a.m. injection (p AXa) activity was observed. Thus the biological anticoagulant effect of 200 IU antiXa/kg of Dalteparin seems to be higher after an evening injection than after a morning injection. A chrono-therapeutic approach with LMWH, as prescribed once daily, deserves further investigation since our results suggest that a preferential injection time may optimise the clinical efficacy of these LMWH.

    Full Text Available Case study method of didactic situations is a modern procedure of effective development of professional abilities in future teachers. I have been using the method for many years in future teachers training in the field of preparation of subject methodologies. A case study does not develop only the subject and didactic competences of future teachers. The self-evaluation and self-reflection processes in students also play an important role. For this purpose the third – analytical – phase of the study is carried out. Two basic methods are used for a complex analysis – macro-analytic and micro- analytic. The macro-analytic method is used to examine the course and the results of the case study: suitability of the used methods, forms and tools; using communicative tools, creating proper climate etc. The micro-analytic method is used to find out changes in students personalities and causes of the outer demonstrations of the case study. One of the examined phenomena is e.g. flexibility and creativity in adjusting the pre-concept to the course of the realization phase of the study.

  18. Ten steps or climbing a mountain: A study of Australian health professionals' perceptions of implementing the baby friendly health initiative to protect, promote and support breastfeeding

    Directory of Open Access Journals (Sweden)

    2011-08-01

    Full Text Available Abstract Background The Baby Friendly Hospital (Health Initiative (BFHI is a global initiative aimed at protecting, promoting and supporting breastfeeding and is based on the ten steps to successful breastfeeding. Worldwide, over 20,000 health facilities have attained BFHI accreditation but only 77 Australian hospitals (approximately 23% have received accreditation. Few studies have investigated the factors that facilitate or hinder implementation of BFHI but it is acknowledged this is a major undertaking requiring strategic planning and change management throughout an institution. This paper examines the perceptions of BFHI held by midwives and nurses working in one Area Health Service in NSW, Australia. Methods The study used an interpretive, qualitative approach. A total of 132 health professionals, working across four maternity units, two neonatal intensive care units and related community services, participated in 10 focus groups. Data were analysed using thematic analysis. Results Three main themes were identified: 'Belief and Commitment'; 'Interpreting BFHI' and 'Climbing a Mountain'. Participants considered the BFHI implementation a high priority; an essential set of practices that would have positive benefits for babies and mothers both locally and globally as well as for health professionals. It was considered achievable but would take commitment and hard work to overcome the numerous challenges including a number of organisational constraints. There were, however, differing interpretations of what was required to attain BFHI accreditation with the potential that misinterpretation could hinder implementation. A model described by Greenhalgh and colleagues on adoption of innovation is drawn on to interpret the findings. Conclusion Despite strong support for BFHI, the principles of this global strategy are interpreted differently by health professionals and further education and accurate information is required. It may be that the current processes used to disseminate and implement BFHI need to be reviewed. The findings suggest that there is a contradiction between the broad philosophical stance and best practice approach of this global strategy and the tendency for health professionals to focus on the ten steps as a set of tasks or a checklist to be accomplished. The perceived procedural approach to implementation may be contributing to lower rates of breastfeeding continuation.

  5. The ten thousand Kims

    International Nuclear Information System (INIS)

    In Korean culture, the names of family members are recorded in special family books. This makes it possible to follow the distribution of Korean family names far back in history. It is shown here that these name distributions are well described by a simple null model, the random group formation (RGF) model. This model makes it possible to predict how the name distributions change and these predictions are shown to be borne out. In particular, the RGF model predicts that for married women entering a collection of family books in a certain year, the occurrence of the most common family name 'Kim' should be directly proportional to the total number of married women with the same proportionality constant for all the years. This prediction is also borne out to a high degree. We speculate that it reflects some inherent social stability in the Korean culture. In addition, we obtain an estimate of the total population of the Korean culture down to the year 500 AD, based on the RGF model, and find about ten thousand Kims.

    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.

    Full Text Available Agile software development methods and techniqueshave been demonstrated to improve employee morale, enhanceend-product quality, and achieve customer satisfaction. Agileadoption always comes with special challenges and thus fundamental organizational changes are necessary for successful outcome. In this paper we present an in-depth case study for adopting Scrum in a multi-team and multi-project situation to a government entity in the United Arab Emirates (U.A.E. While there are many successful stories for adopting Scrum in large and small organizations, there is little known about adoption stories in a multi-project/multi-team environments. In this paper we present a case study for an unsuccessful adoption of Scrum in a government entity in the U.A.E. The government entity under study have used the traditional waterfall approach for many years and decided to move to Agile software development method.This study highlights the challenges faced during the adoptionof Scrum method with recommendations to address them. Eachorganization has its unique properties and one case study is not enough to draw conclusions for the U.A.E environment. However, the results obtained from this paper help software engineers to better understand the development environment and context factors for software projects in the U.A.E and many lessons may be learned for future Agile adoption.

  11. Does present use of cardiovascular medication reflect elevated cardiovascular risk scores estimated ten years ago? A population based longitudinal observational study

    Straand Jørund

    2011-03-01

    Full Text Available Abstract Background It is desirable that those at highest risk of cardiovascular disease should have priority for preventive measures, eg. treatment with prescription drugs to modify their risk. We wanted to investigate to what extent present use of cardiovascular medication (CVM correlates with cardiovascular risk estimated by three different risk scores (Framingham, SCORE and NORRISK ten years ago. Methods Prospective logitudinal observational study of 20 252 participants in The Hordaland Health Study born 1950-57, not using CVM in 1997-99. Prescription data obtained from The Norwegian Prescription Database in 2008. Results 26% of men and 22% of women aged 51-58 years had started to use some CVM during the previous decade. As a group, persons using CVM scored significantly higher on the risk algorithms Framingham, SCORE and NORRISK compared to those not treated. 16-20% of men and 20-22% of women with risk scores below the high-risk thresholds for the three risk scores were treated with CVM, while 60-65% of men and 25-45% of women with scores above the high-risk thresholds received no treatment. Among women using CVM, only 2.2% (NORRISK, 4.4% (SCORE and 14.5% (Framingham had risk scores above the high-risk values. Low education, poor self-reported general health, muscular pains, mental distress (in females only and a family history of premature cardiovascular disease correlated with use of CVM. Elevated blood pressure was the single factor most strongly predictive of CVM treatment. Conclusion Prescription of CVM to middle-aged individuals by large seems to occur independently of estimated total cardiovascular risk, and this applies especially to females.

  12. 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.

    Singer Peter A

    2001-04-01

    Full Text Available Abstract Background Why waiting lists arise and how to address them remains unclear, and an improved understanding of these waiting list "dynamics" could lead to better management. The purpose of this study is to understand how the current shortage in radiation therapy in Ontario developed; the implications of prolonged waits; who is held accountable for managing such delays; and short, intermediate, and long-term solutions. Methods A case study of the radiation therapy shortage in 1998-99 at Princess Margaret Hospital, Toronto, Ontario, Canada. Relevant documents were collected; semi-structured, face-to-face interviews with ten administrators, health care workers, and patients were conducted, audio-taped and transcribed; and relevant meetings were observed. Results The radiation therapy shortage arose from a complex interplay of factors including: rising cancer incidence rates; broadening indications for radiation therapy; human resources management issues; government funding decisions; and responsiveness to previous planning recommendations. Implications of delays include poorer cancer control rates; patient suffering; and strained doctor-patient relationships. An incompatible relationship exists between moral responsibility, borne by government, and legal liability, borne by physicians. Short-term solutions include re-referral to centers with available resources; long-term solutions include training and recruiting health care workers, improving workload standards, increasing compensation, and making changes to the funding formula. Conclusion Human resource planning plays a critical role in the causes and solutions of waiting lists. Waiting lists have harsh implications for patients. Accountability relationships require realignment.

  19. Ten Challenges for Decision Neuroscience

    Directory of Open Access Journals (Sweden)

    ScottAHuettel

    2010-09-01

    Full Text Available Decision neuroscience research, as currently practiced, employs the methods of neuroscience to investigate concepts drawn from the social sciences. A typical study selects one or more variables from psychological or economic models, manipulates or measures choices within a simplified choice task, and then identifies neural correlates. Using this “neuroeconomic” approach, researchers have described brain systems whose functioning shapes key economic variables, most notably aspects of subjective value. Yet, the standard approach has fundamental limitations. Important aspects of the mechanisms of decision making – from the sources of variability in decision making to the very computations supported by decision-related regions – remain incompletely understood. Here, I outline ten outstanding challenges for future research in decision neuroscience. While some will be readily addressed using current methods, others will require new conceptual frameworks. Accordingly, a new strain of decision neuroscience will marry methods from economics and cognitive science to concepts from neurobiology and cognitive neuroscience.

    Sánchez-Rubio, Patricia; Rodríguez-Romero, Ruth; Castro-Tejero, Pablo

    2014-01-01

    The purpose of this study was to quantify the systematic and random errors for various disease sites when daily MVCT scans are acquired, and to analyze alterna- tive off-line verification protocols (OVP) with respect to the patient setup accuracy achieved. Alignment data from 389 patients (9,418 fractions) treated at ten differ- ent anatomic sites with daily image-guidance (IG) on a helical tomotherapy unit were analyzed. Moreover, six OVP were retrospectively evaluated. For each OVP, the frequency of the residual setup errors and additional margins required were calculated for the treatment sessions without image guidance. The magnitude of the three-dimensional vector displacement and its frequency were evaluated for all OVP. From daily IG, the main global systematic error was in the vertical direction (4.4-9.4 mm), and all rotations were negligible (less than 0.5°) for all anatomic sites. The lowest systematic and random errors were found for H&N and brain patients. All OVP were effective in reducing the mean systematic error to less than 1 mm and 0.2° in all directions and roll corrections for almost all treatment sites. The treatment margins needed to adapt the residual errors should be increased by 2-5 mm for brain and H&N, around 8 mm in the vertical direction for the other anatomic sites, and up to 19 mm in the longitudinal direction for abdomen patients. Almost 70% of the sessions presented a setup error of 3 mm for OVPs with an imaging frequency above 50%. Only for brain patients it would be feasible to apply an OVP because the residual setup error could be compensated for with a slight margin increase. However, daily imaging should be used for anatomic sites of difficult immobilization and/or large interfraction movement.  PMID:25493505

  4. Dez anos de experiência com cirurgia micrográfica pelo método de Munique: relato de 93 casos operados A ten-year experience with the Munich method of micrographic surgery: a report of 93 operated cases

    Directory of Open Access Journals (Sweden)

    Luis Fernando Figueiredo Kopke

    2005-12-01

    Full Text Available FUNDAMENTOS: A cirurgia de Mohs é um dos métodos mais eficazes de tratamento dos carcinomas basocelulares. A expansão de seus conceitos possibilitou o surgimento de outros métodos de checagem de margens cirúrgicas igualmente eficazes. O método de Munique é um exemplo disso. OBJETIVOS: Avaliar a eficácia da cirurgia micrográfica pelo método de Munique em um estudo de coorte com 10 anos de duração. MÉTODOS: 93 pacientes com 96 tumores cutâneos foram tratados com cirurgia micrográfica pelo método de Munique, participando de um protocolo de acompanhamento, no período de maio de 1994 a julho de 2004. RESULTADOS: 61,4% dos tumores eram recidivados; 42,3% eram recidivados mais de uma vez; 53% eram do tipo esclerodermiforme. A média do maior diâmetro dos tumores foi de 1,58cm e do menor 1,10cm. Em 95% dos casos se obteve a extirpação total do tumor, com até três estágios. A localização mais comum foi a nasal (46,3%, seguida da periocular (18,9% e da frontal (11,5%. Perdeu-se o contato apenas com dois pacientes. Dos 96 tumores operados, apenas 11 têm tempo de seguimento inferior a dois anos. 56 pacientes foram seguidos por pelo menos cinco anos, e 45 (47,3%, por mais de seis anos. Apenas um caso de recidiva foi verificado, tendo ocorrido no sexto ano de observação. CONCLUSÃO: O método de Munique é um método eficiente de cirurgia micrográfica, tanto quanto o método de Mohs. Este trabalho fornece mais um indício de que o conceito de cirurgia micrográfica deve ser ampliado para cirurgia microscopicamente controlada, e não ficar ligado estritamente ao termo cirurgia de Mohs.BACKGROUND: Mohs surgery is one of the most effective treatments for basal cell carcinomas. The expansion of its concepts enabled developing other equally effective methods to check surgical margins, and the Munich method is an example. OBJECTIVES: To evaluate the effectiveness of the Munich method of micrographic surgery in a ten-year cohort study. METHODS: Ninety-three patients with a total of 96 skin tumors were treated with the Munich method of micrographic surgery, taking part in a follow-up protocol, from May 1994 through July 2004. RESULTS: Of all tumors, 61.4% were recurrent, 42.3% were recurrent more than once, and 53% were of the sclerodermiform type. The mean larger diameter was 1.58cm, and the mean smaller diameter was 1.10cm. In 95% of the cases, total extirpation of the tumor was obtained in three stages. The most common site was nasal (46.3%, followed by periocular (18.9% and frontal (11.5%. Two patients were lost in follow-up. Of the 96 operated tumors, only 11 had a follow-up time shorter than 2 years. Fifty-six patients were followed for at least 5 years, and 45 (47.3% for over 6 years. A single relapse was observed, which took place in the sixth year of observation. CONCLUSION: The Munich method is an efficient method of micrographic surgery, as good as the Mohs method. This study provides further evidence that the concept of micrographic surgery must be broadened to surgical excision with microscopic margin control, rather than linking it exclusively to the term "Mohs micrographic surgery".

  19. Transcultural Nursing: Basic Concepts and Case Studies

    Science.gov (United States)

    Fernandez, Kathy

    Created by the nonprofit organization Transcultural Nursing, this very useful website covers both basic concepts related to diversity as well as providing an array of case studies designed to help students, nurses and anyone practicing in the health professions better understand cultural diversity. The case studies are nicely designed, divided by general cultural community (Hispanic, Middle Eastern, Deaf, Asian, Afro American and Migrant Worker) with basic information about religion(s) or other demographic information that might relate to that particular group. Following the general information are three or four case studies illustrating specific instances where cultural differences came into play in a nursing or medical situation. The site also has an introductory area, which outlines some basic concepts including defining terms such as, cultural values and ethnocentrism. A page dedicated to the topic of third world nursing offers insight into this type of hands on experience in nursing in diverse communities, and a list of references and related links round out this very useful site.

  20. Systemic Design: Two Canadian Case Studies

    Directory of Open Access Journals (Sweden)

    Alex Ryan

    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.

    Full Text Available Abstract Background Urinary tract infection (UTI is one of the most common infectious diseases at the community level. In order to assess the adequacy of the empirical therapy, the prevalence and the resistance pattern of the main bacteria responsible for UTI in the community (in Aveiro, Portugal was evaluated throughout a ten-year period. Methods In this retrospective study, all urine samples from patients of the District of Aveiro, in ambulatory regime, collected at the Clinical Analysis Laboratory Avelab during the period 2000–2009 were analysed. Samples with more than 105 CFU/mL bacteria were considered positive and, for these samples, the bacteria were identified and the profile of antibiotic susceptibility was characterized. Results From the 155597 samples analysed, 18797 (12.1% were positive for bacterial infection. UTI was more frequent in women (78.5% and its incidence varied with age, affecting more the elderly patients (38.6%. Although E. coli was, as usual, the most common pathogen implicated in UTI, it were observed differences related to the other bacteria more implicated in UTI relatively to previous studies. The bacteria implicated in the UTI varied with the sex of the patient, being P. aeruginosa a more important cause of infection in men than in women. The incidence of the main bacteria changed over the study period (P. aeruginosa, Klebsiella spp and Providencia spp increased and Enterobacter spp decreased. Although E. coli was responsible for more than an half of UTI, its resistance to antibiotics was low when compared with other pathogens implicated in UTI, showing also the lowest percentage of multidrug resistant (MDR isolates (17%. Bacteria isolated from females were less resistant than those isolated from males and this difference increased with the patient age. Conclusions The differences in sex and age must be taken into account at the moment of empirical prescription of antimicrobials. From the recommended antimicrobials by the European Association of Urology guidelines, the first line drugs (pivmecillinam and nitrofurantoin and the alternative antibiotic amoxicillin-clavulanic acid (AMX-CLA are appropriate to treat community-acquired UTI, but the fluoroquinolones should not be suitable to treat male infections and the trimethoprim-sulfamethoxazole (SXT shall not be used in the treatment of UTI at this level.

    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.

    2010-01-01

    Many of today’s farming systems are composed of purpose-built computerized farming devices such as spraying equipments, harvesters, fertilizer spreaders and so on. These devices produce large amounts of data. In most of the cases, it is essential to store data for longer time periods for analysis and reporting purposes. This paper presents the LandIT database; which is result of the LandIT project, which refers to an industrial collaboration project that developed technologies for communication and data integration between farming devices and systems. The LandIT database in principal is based on the ISOBUS standard; however the standard is extended with additional requirements, such as gradual data aggregation and flexible exchange of farming data. This paper describes the conceptual and logical schemas of the proposed database based on a real-life farming case study.

  9. 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 comp 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.

  19. 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 case study the effective number of inputs was reduced from 30 to 7 in the screening stage, and just 2 inputs were found to explain 82.8% of the output variance. A combined total of 500 runs of the computer code were used. Conclusion These case studies illustrate the use of Bayesian statistics to perform detailed uncertainty and sensitivity analyses, integrating multiple information sources in a way that is both rigorous and efficient.

    It is not uncommon for children or young adults to have congenitally missing teeth or early loss of teeth from trauma or caries. The restorative options are typically bridges, implants, and removable appliances. Often overlooked and misunderstood, another treatment option exists in autotransplantation, where a tooth is moved from one site to another in the same individual. Autotransplantation is well studied and has predictable results comparable to implants, with reported success rates often greater than 90%. This article will provide an overview of autotransplantation, its indications, advantages, complications, and treatment considerations, along with a case of a third molar autotransplant that will serve to highlight these points.

    This is a case study presented by the University of Pittsburgh Department of Pathology in which a 64-year-old woman with a long history of IBS presents with a recent "exacerbation of diarrhea, increased abdominal cramping, and weight loss." Visitors are given both the gross and microscopic descriptions, including images, and are given the opportunity to diagnose the patient. This is an excellent resource for students in the health sciences to familiarize themselves with using patient history and laboratory results to diagnose disease. It is also a helpful site for educators to use to introduce or test student learning in gastrointestinal pathology.

    1985-10-01

    3 lists were compiled to answer the question of what countries have experienced the most population growth from World War II to the present. The 1st list includes the 10 countries which accounted for the largest gain in world population. The 2nd list shows the 10 countries with the highest growth rates of the 150 or so most populous countries in the world. The last list also shows countries ranked by growth rate but is limited to those with a current population of at least 10 million. To deal with the fact that some countries did not exist at 1 of the reference points, a set of estimates for 1940 provided a convenient starting point. China and India headed the list of countries ranked by absolute gains. They contributed half again as much growth as the next 8 nations combined. Altogether Asia, home to almost 60% of the world's population, captured 5 of the top 10 slots. The US and the USSR are the only developed countries on the list. The Soviet Union also presents the 1st case on the list of a country with a lower ranking in population gain (6th) than in absolute size in 1985 (3rd). Many of the population giants of 1940 (Japan, Great Britain, Germany, France, and Italy) are not on the list. Despite large base populations, their growth has been slow in the intervening years. All of the countries with the highest growth rates experienced over 3% annual average growth during the last 45 years: Kuwait, United Arab Emirates, Libya, Venezuela, Costa Rica, Kenya, Ivory Coast, Mexico, Honduras, and Syria. The influence of immigration is much in evidence in this list and explains otherwise unachievable rates of growth. The top 4 countries in annual rates of growth are all oil exporters. The top 3 countries in the 3rd list -- Venezuela, Kenya, and Mexico -- are carried over from the 2nd list, sharing the characteristics of rapid population growth and substantial base populations. The geographic mix of this list is notable. Asia, Africa, and Latin America each have at least 3 countries represented. Strikingly absent are countries from the developed world. Rapid growth occurs in countries of widely varying sizes. PMID:12267382

    Bves was discovered in 1999 by two independent laboratories using screens to identify novel genes that were highly expressed in the developing heart (Reese et al., 1999; Andree et al., 2000). As an evolutionarily conserved transmembrane protein, Bves is postulated to play a role in cell adhesion and cell motility. In studies of Bves protein disruption, there have been multiple phenotypes, but few molecular mechanisms have been advanced to explain the underlying cause of these phenotypes. As t...

    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.

    Full Text Available Abstract Background Hepatoblastoma (HBL and hepatocellular carcinoma (HCC are respectively the first and the second most common pediatric malignant liver tumors. The purpose of this study was to evaluate the combined use of the ultrasound examination and the assessment of the patients' clinical features for differentiating HBL from HCC in children. Methods Thirty cases of the confirmed HBL and 12 cases of the confirmed HCC in children under the age of 15 years were enrolled into our study. They were divided into the HBL group and the HCC group according to the histological types of the tumors. The ultrasonic features and the clinical manifestations of the two groups were retrospectively analyzed, with an emphasis on the following parameters: onset age, gender (male/female ratio, positive epatitis-B-surface-antigen (HBV, alpha-fetoprotein increase, and echo features including septa, calcification and liquefaction within the tumors. Results Compared with the children with HCC, the children with HBL had a significantly younger onset age (8.2 years vs. 3.9 years, P Conclusion Ultrasonic features combined with clinical manifestations are valuable for differentiating HBL from HCC in children.

  1. The Danish National Case Study Report

    DEFF Research Database (Denmark)

    Brodersen, SØsser; JØrgensen, Michael SØgaard

    2003-01-01

    This report is the Danish case study report in the EU-financed project INTERACTS, which analyses experience and expectations to the interaction between NGOs, Science Shops and universities. The report analyses potentials and barriers to NGO’s and similar civil society groups’ use of research and science through co-operation with Science Shops as a mediator between universities and civil society. The Danish national case study report analyses three projects carried out through the Science Shops at DTU and RUC. One case is a co-operation between two DTU students and an NGO, whom is working towards promoting the use of bicycles. The project addresses how different actors perceive and understand the bicycles as technology, and how this is incorporated in traffic strategies and planning. A second case is a co-operation between two DTU students and a day-care centre, aiming at investigating storage facilities for organic food and the possibilities of local supply of organic food to the day-care centre. The third case is a co-operation between four RUC students and a local branch of a larger NGO working with nature and environment. This co-operation aims at investigating the pollution level in a village pond. Each case is described and reflected separately. A cross-analysis analyses the interactions among the involved actor group (clients, students, researchers, and Science Shops) discussing how the knowledge in the projects were developed and how the knowledge were used by the actors to try to gain impact on either research development or societal discourses. When civil society groups request assistance through the Science Shops, their need for knowledge and research is based on a need for scientific documentation of a certain topic, a need for enhancement of new knowledge and/or a need for development of new solutions and perspectives to problems. All three types of knowledge need is covered by one or more of the cases. The cases show that NGOs perceive research done through universities as neutral and creating more legitimacy than research done by the organisation itself. The cases show that all three NGO’s have used the results and findings to try influencing the societal discourses, and that the results and findings have helped two of the NGOs to gain influence. The analysis further shows that this influence seems to depend on the ability of the NGOs to build alliances with other actors. Knowledge in itself is not enough to get influence. The cases show that some students choose to conduct research through the Science Shops, because their research can be beneficial for someone, who does not have access to science and knowledge. Aspects like the possibility of gaining skills in co-operation and communication and knowledge about real life problems are also part of the students’ considerations when they chose to co-operate with civil society organisations through a Science Shop. Supervisors and scientists get engaged in Science Shop projects either because the topic of the investigation is within their own research area, because they find the topic interesting or because they see the project as a possibility to recruit students for later thesis projects or research projects. The challenges in the co-operation with civil society groups are to secure the scientific level in the projects, design the projects so it fits into the university schedule, without leaving out the time perspective of the clients, and secure the research is applicable for the clients and based on their need for knowledge. The case studies have shown different roles of a Science Shop. All Science Shops have a role as mediator between science and civil society by establishing contact between students, researchers and civil society organisations, but a Science Shop can also have a role as incubator in curricula and research development within the university based on the knowledge needs raised by civil society organisations. Through these activities a Science Shop might contribute to societal discourses, like when the Science Shop at DTU started addre

These examinations are delivered in partnership with a commercial online testing company as part of the Industry Master?s degree at Charles Sturt University (CSU. The Industry Master?s degree is an academic program for students currently employed in the IT industry. Using Internet Based Testing (IBT, these students are examined in test centres throughout the world. This offers many benefits. For example, students have the freedom of sitting exams at any time during a designated interval. Computer-based testing also provides instructors with valuable feedback through test statistics and student comments. In this paper, we document CSU?s use of the IBT system, including how tests are built and delivered, and how both human and statistical feedback is used to evaluate and enhance the testing process.

    California is the largest cement producing state in theU.S., accounting for between 10 percent and 15 percent of U.S. cementproduction and cement industry employment. The cement industry inCalifornia consists of 31 sites that consume large amounts of energy,annually: 1,600 GWh of electricity, 22 million therms of natural gas, 2.3million tons of coal, 0.25 tons of coke, and smaller amounts of wastematerials, including tires. The case study summarized in this paperfocused on providing background information, an assessment ofenergy-efficiency opportunities and barriers, and program recommendationsthat can be used by program planners to better target products to thecement industry. The primary approach to this case study involvedwalk-through surveys of customer facilities and in depth interviews withcustomer decision makers and subsequent analysis of collected data. Inaddition, a basic review of the cement production process was developed,and summary cement industry energy and economic data were collected, andanalyzed. The analysis of secondary data provides background informationon the cement industry and identification of potential energy-efficiencyopportunities. The interviews provide some understanding of the customerperspective about implementation of energy-efficiencyprojects.

    Full Text Available Means of accommodation involve a wide range of social actors and agents, as well as different business models. Management strategies in this sector have been increasingly important for long-term sustainability and competitiveness of business organizations. This study aims to analyze the interactions between apart-hotels and their stakeholders to foster an improvement of services provided, aligning the interface of strategic management from the point of view of managers and their key stakeholders. It is an exploratory study, with qualitative chacter, along with multiple case studies of the following establishments: Travel Inn, Hotels Slaviero and Etoile george v. Brazilian enterprises, which manage lodging facilities with apart-hotel concepts, combining features that enable comparative analysis of the study. For conceptual understanding, this study was based on literature about stakeholders, taking the work of Freeman (1984 and Freeman et al (2010 as main references. The research was conducted through semi-structured interviews with managers of lodging facilities and their key stakeholders and through direct observation and documentation. We found that not all groups of influence are considered in the planning of service flats. However, the organizations surveyed indicated that the market has realized the importance of the groups that exert influence and are influenced by their goals, and are therefore increasingly alert for integration of such groups in their strategic planning.

    Full Text Available Trata-se de um estudo de corte transversal, realizado com o objetivo de investigar as razões que levaram adolescentes a provocarem o aborto, relacionando com idade e tipo de escola que frequentavam. A amostra foi calculada considerando o número de internações para curetagem pós-abortamento. Usou-se [...] como instrumento um questionário semiestruturado, anônimo, aplicado em dez escolas, sorteadas dentre todas da cidade de Maceió (Alagoas), pesquisando-se adolescentes dos 12 aos 19 anos, do sexo feminino. Os dados foram analisados pelo Programa Epi Info, usando-se odds ratio e risco relativo para verificar associação entre variáveis e intervalo de confiança a 95%. Em uma amostra de 2.592 jovens, 559 (21,6%) tinham vida sexual ativa, 182 (7,0%) referiram ter engravidado e 149 (26,7%) abortado. Medo da reação dos pais, idade, falta de apoio do companheiro e rejeição da gravidez foram razões para provocar o aborto, sendo medo a mais citada, em ambos os tipos de escola. O aborto foi mais citado nas escolas públicas, sendo significativo e protetor o risco para abortar antes dos 15 anos, e significativa a relação entre abortar e estudar em escolas públicas. O medo da reação dos pais como razão mais frequente sugere a necessidade de novos estudos sobre sexualidade e comunicação entre pais e filhos. Abstract in english This is a cross-cut study that was carried out with the objective of investigating the causes through which adolescents have provoked abortion, relating it to age and the type of school attended. The sample was calculated by taking into account the number of hospital admissions for post-abortion cur [...] ettage. A semi-structured and anonymous questionnaire was used as a research instrument which was applied in ten schools randomly chosen among all schools, of Maceió (Alagoas, Brazil), to reach 12-19 years old female teenagers. The data were assessed by the Epi Info Program making use of odds ratio and a relative risk to verify any association among variables and a confidence interval at 95%. At a sample of 2,592 adolescents, 559 (21.6%) had an active sexual life, 182 (7.0%) informed to have been pregnant and 149 (26.7%) to have aborted. The fear of the parents' reaction, age, lack of support of the partner and pregnancy rejection were the explanation to stimulate abortion. Fear was the most mentioned cause in both types of school. Abortion was more mentioned in public schools, being significant and protective the risk of aborting before the age of 15. The fear of the parents' reaction as a frequent cause suggests the necessity for additional studies on sexuality and communication between parents and children.

    2010-03-22

    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.

    Background Hepatoblastoma (HBL) and hepatocellular carcinoma (HCC) are respectively the first and the second most common pediatric malignant liver tumors. The purpose of this study was to evaluate the combined use of the ultrasound examination and the assessment of the patients' clinical features for differentiating HBL from HCC in children. Methods Thirty cases of the confirmed HBL and 12 cases of the confirmed HCC in children under the age of 15 years were enrolled into our study. They were divided into the HBL group and the HCC group according to the histological types of the tumors. The ultrasonic features and the clinical manifestations of the two groups were retrospectively analyzed, with an emphasis on the following parameters: onset age, gender (male/female) ratio, positive epatitis-B-surface-antigen (HBV), alpha-fetoprotein increase, and echo features including septa, calcification and liquefaction within the tumors. Results Compared with the children with HCC, the children with HBL had a significantly younger onset age (8.2 years vs. 3.9 years, P < 0.001) and a significantly smaller frequency of positive HBV (66.7% vs. 13.3%, P < 0.001). The septa and liquefaction were more frequently found in HBL than in HCC (25/30, 83.3% vs. 2/12, 16.7%, P < 0.001; 17/30, 56.7% vs. 3/12, 25%, P = 0.02). When a combination of the liquefaction, septa, negative HBV and onset age smaller than 5 years was used in the evaluation, the sensitivity was raised to 90%, the accuracy was raised to 88%, and the negative predictive value was raised to 73%. Conclusion Ultrasonic features combined with clinical manifestations are valuable for differentiating HBL from HCC in children. PMID:21702993

    "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.

    Professional and student musicians are at high risk of acquiring a playing-related injury at some point in their careers. Yet, specialized healthcare for musicians is scarce and expensive for most self-employed musicians. Diagnosing these injuries is challenging, and simply taking a break from an activity that has caused physical problems does not address the ergonomic and biomechanic causes of the problem. Under these circumstances, it is not surprising that musicians are reluctant to seek care, and when they do, lack trust in the care that is provided to them. This article is a case presentation of the experiences of a graduate student musician studying performance at a North American university. A narrative style is used to reflect the quality and nature of experiences this musician encountered, followed by a discussion of how to advance a more participatory and holistic approach to enabling return to function.

    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.

    2011-01-01

    How does one learn about primary health care? Some might attend public health schools while others will find different ways to explore this fascinating field on their own. One particularly nice resource on the subject is this course from the Johns Hopkins School of Public Health. Offered as part of the Open Course Ware initiative, the course was first developed in the fall of 2011 and was co-taught by Henry Taylor and Henry Perry. It was designed to introduce students to "the origins, concepts, and development of community-based primary health care through case studies from both developing and developed countries." The materials here include the syllabus, lecture materials, readings, and assignments. Within the Lecture Materials section visitors can watch or listen to conversions on the roots of community-based primary health care and women's empowerment via public health. Additionally, visitors can look over the course assignments or check out some of the discussion questions.

    Stephens, Shelly J

    2009-11-01

    In 1991, Amway formed an industrial hazardous materials (hazmat) team in order to respond quickly and efficiently to potential chemical spills. The company's goals were, and still are today, to protect employees, the environment and the local community, and to reduce the amount of resulting downtime. In 1991, the hazmat team was very well funded, enabling it to become a discrete department with its own management staff and nearly 100 hazmat volunteers. Due to changes in the business climate, Amway reorganised in 2000/01, and the hazmat team became part of a company that incorporated contract work into its scope. When this reorganisation occurred, the hazmat team was thoroughly re-evaluated. Its response function was maintained, but was systematically reinvented in the most lean way practicable while still meeting corporate goals. This case study represents Amway's hazmat team's journey through the evaluation process and subsequent reorganisation. PMID:20378491

  5. Case studies of some industrial radiography accidents

    International Nuclear Information System (INIS)

    Industrial radiography practice is the widely deployed application using radiation sources Iridium-192 and Cobalt-60 for non-destructive evaluation of flaws in manufactured products. This practice is potentially most hazardous of all the industrial applications of radiation as the radiation sources are generally used in project sites where provision of in-built safety is difficult and the radiation sources are taken out of the shielded source housing during radiography exposures. Throughout the history of industrial radiography, accidents with some sources have occurred that have resulted in fatalities and injury. Case studies of recent industrial radiography incidents that have occurred in India involving S conduit radiography exposure devices, the reasons for the incidents and the lessons learned from these experiences are discussed in this paper.

  6. Environmental Comparative Risk Assessment: A Case Study

    International Nuclear Information System (INIS)

    Health and environmental impacts associated with energy production and industrial activities as well as food production and agricultural activities have had great concern in the last decades. Early activities emerged in late 80s of the last century through an Inter- Agency project (lAEA, UNDY, WHO, ... ) on the comparative risk assessment from energy systems and industrial complexes. A work-shop on Risk Assessment and Management in large industrial areas was held in Alexandria Egypt on 20-33 Det 1993, sponsored by IAEA. Several conferences, experts work groups and workshops were held there of Recent trends in determining risks are: 1. Use of probabilistic risk assessment approach to identify hazardous activities and accident scenario. 2. development of data base on failure probabilities and appropriate physical models. 3. Development of related directives and regulations and criteria Comparative risk assessment case study as a tool for comparing risk is emphasized Criteria of exposure to human and ecological risks are addressed

    The intention of this paper is to conclude the management approach by the case study of Chinese enterprise. There are a lot of management approaches in practice, one of the most influential and famous one is management by objective which is invented by the father of modern management discipline Peter F Drucker, he observed the case of American most successful enterprise such as GM and then concluded and created the relevant meaningful management tools, in effect, such valuable management theory is stemmed from the practice of management, and the premise is that there must have great enterprise first then the effective management way could be concluded, therefore, many management theories are created in America because that the US have many great organizations other countries did not have at that time. However, after more than thirty years’ efforts and accumulation of the development of reform and openingup in China, it is our pride that such accumulation has lead to a lot of successful enterprises in China, one of such great companies is Alibaba, which is created at the right time and the right place. Alibaba is chosen because that the reason of its success is different with other enterprises in China and even in the world, it is a company which never place high value on benefit, however, it is more successful than any other companies which are benefit-oriented, by the case study we find out that the secret of its success is nothing but an innovational practice of management, that is, Management by Values (MBV. As it is shown in this paper: Alibaba, the mission of which is to create easy way to trade anywhere. Such visionary mission gives Alibaba a dream of unlimited growth space, but only the mission itself is not enough, effective management by values helps Alibaba to realize this potential. Its practice implies the content of values and how to manage it in an organization; besides, it tells us the bases of managing by values, which are about the character of the leader and the purpose of the organization, Jack ma and Alibaba are good cases in point, Jack ma himself is poor in education, but he is really a practical dreamer and is also a leader who is good at developing others, as an organization , the purpose of Alibaba is the benefit of outside instead of its profit, both are really precious in today’s business; and what is more, its experience also witnesses the process of management by values: start an enterprise with an agreeable basic principles of values ; shaping the values when the enterprise begin to take shape; evaluating the values of all the employees when the enterprise become big; at last, the developing of values itself should be an important part of this management, which part of the values should be persisted, which part might be changed, Alibaba provide us a good case in point.

  8. Groundwater study by using radioisotope tracer - some case studies

    International Nuclear Information System (INIS)

    This study is to investigate the groundwater behaviour by using radioisotope tracer. The main objectives of the study are to determine the groundwater flowrate and its direction. The equipment that we used in this study are rheometer and direction monitoring system - MINT water spy. In this study, the single well method is used to determine the groundwater velocity and direction. The method involved the injection of radioisotope tracer into the borehole and monitor its concentration over a certain period of time. Radioactive isotopes artificially injected at a well-define point of the system under investigation. Groundwater movement studies have been performed for example in Paya Terubong (Penang), Klian Intan (Perak), and Taman Makmur (Negeri Sembilan). The application of these techniques have shown that in many cases they not only confirm the results obtained by classical hydrological methods but as an alternative they provide more information and immediate answers to some hydrological problems.

  9. 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) disaster financing and budgetary burdens, and (iii) economic risk balancing in urban planning. The results of the conducted case studies are discussed with regard to method development for integrated assessment of landslide risk. References Crovelli, R.A., Coe, J.A., 2009.

    Objective To assess the effect of ADHD and its treatment on growth outcomes in children followed into adulthood. Study design Two identically designed, longitudinal, case-control studies of males and females with and without ADHD were combined. 124 and 137 control and subjects with ADHD, respectively, provided growth information at the 10–11 year follow-up. We used linear growth curve models to estimate the effect of time on change in height, and whether this effect differed by sex and ADHD status. We also examined the effect of stimulant treatment on growth outcomes. Results We found no evidence that ADHD was associated with trajectories of height over time, or differences at follow-up in any growth outcomes. Similarly, we found no evidence that stimulant treatment was associated with differences in growth. However, among subjects with ADHD, major depression was associated with significantly larger weight in females and smaller height in males. Conclusions Our results do not support an association between deficits in growth outcomes and either ADHD or psychostimulant treatment for ADHD. These findings extend the literature on this topic into young adulthood, and should assist clinicians and parents in formulating treatment plans for children with ADHD. PMID:20605163

    Full Text Available To establish the perception of employees regarding diversity management at South Africa's largest residential university, the questionnaires of Gardenswartz & Rowe (1993 was adapted and a case study approach with a sample of 25 employees was used. The diversity audit measured the sample's perceptions on symptoms of diversity related problems; openness to change of the university; the status quo regarding diversity management; organisational barriers to diversity; the valuing of diversity; and the management of diversity by managers or supervisors. It was found that a high number of symptoms of diversity-related problems are perceived and that respondents believed that the university is relatively unresponsive to the need to change. The university was believed to be in a mono cultural stage of development and barriers to developing into a multicultural organisation were identified. Respondents did report a very positive attitude towards diversity but perceived that certain procedures are not supportive.

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

    Directory of Open Access Journals (Sweden)

    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.

  14. Bilingual education in Slovakia: A Case Study

    Silvia Pokriv?áková

    2013-06-01

    Full Text Available Bilingual education is one of the areas in contemporary education that brings out some important controversies (philosophical, conceptual, sociological, political, economical, etc. and thus calls for extensive and intensive debate. Bilingual education in Europe (and here the European Union countries are meant has gained a very different status, due to the general European policy of developing language diversity and promoting “European plurilingualism and multilingualism”. In Slovakia, one of the younger members of the EU, bilingual education became an extraordinarily popular instrument for the fulfilment of this task.  Since the specifically defined topic of bilingual education and its current status in Slovakia has not been studied and systematically reviewed yet, the research presented in this paper was designed as a single-phenomenon revelatory case study investigating seven research areas: reflection of bilingual education in school legislation and state pedagogical documents, purposes of bilingual education in Slovakia, its organization (levels and types of schools, foreign languages incorporated, teachers, structure of bilingual schools curricula, types of bilingual education applied at Slovak bilingual schools, and how bilingual education is both reflected in and saturated by the latest research findings. The conclusions presented in the paper were collected from multiple sources: state curriculum, statistical data published by the Slovak Ministry of Education or its partner institutions, international treaties on establishing and supporting bilingual sections of schools, bilingual schools curricula, interviews with school directors, teachers, and learners, direct observations at bilingual schools, research studies and research reports, etc. In the conclusion, bilingual education in Slovakia is identified as a unique, dynamically developing system which is both significantly shaped by the foreign language education policy promoted by the European Council (1995 as well as bears some specific characteristics, determined by its unique historical, political, and socio-cultural contexts. The paper includes partial results of the research project KEGA 036UKF-4/2013 Creating university textbooks and multimedia courses for a new study program funded by the Ministry of Education of the Slovak Republic.

  15. EST Case Studies and Perspectives in Japan

    International Nuclear Information System (INIS)

    Results and discussion of the Environmentally Sustainable Transport (EST) Case Study for Japan are introduced within this paper. According to procedures defined in the EST project by the OECD, the targets for a major reduction of environmental load within the transport sector are defined to be CO2, NOx, PM, and VOC. Three scenarios to accomplish these reduction targets, with respect to these environmental loads are detailed: a techno-optimistic scenario (EST1), a transport demand management scenario (EST2), and a composite scenario (EST3). All of the scenarios are examined and compared to the business-as-usual (BAU) scenario. Policy instruments to realize these scenarios and their socio-economic impacts were, to date, not assessed within the study. Utilizing a 'back casting' methodology, expected changes in technology and transport behavior in order to meet an ultimate target of emissions reduction were examined by each of the scenarios. The objective areas consisted of a national study, encompassing the whole of Japan, and a regional (Aichi prefecture) study. The forecasts indicate that CO2 emissions increase by about 10% in Japan but are almost stable in Aichi prefecture. NOx and HC emissions in 2030 are about half, and PM emissions around one quarter of those in 1990 in Aichi prefecture. The results of the back casting indicate that CO2 and NOx reduction targets have severely restrictive conditions. The achievement of targets utilizing only EST1 and EST2 is totallyts utilizing only EST1 and EST2 is totally unfeasible. Even in the combined EST3 scenario, and in light of current trends requirements must include strong recommendations for change such as the significant wide spread use of fuel cell vehicles and the reduction of freight transport demands, and hence the scenario still needs to be discussed further

  16. Quality improvement initiatives in a case management service: case study.

    Science.gov (United States)

    Davies, Deborah J

    2015-01-01

    This article explores the importance of quality practices in underpinning the person-centred approach at a Community Options Program (COP) case management service in northern NSW. The NSW community care sector does not have a statutory excellence body to identify, promote and support improved practices and quality and safety across community services, and therefore the COP provider decided to establish a dedicated role to focus on the quality improvement of its service. The subsequent quality improvement initiatives have included mapping the clients' journey through the service, identifying areas to standardise practice, and creating service pathways. The clients' journey was used as the framework to identify where standardised practice was required, and a robust process was implemented to develop over 25 good practice guidelines and tools that addressed the variations in practice and enabled the service pathways to be developed. Prior to trialling the guidelines and tools, staff received education sessions on the anticipated changes to practice, and the practicality and applicability of the guidelines were evaluated at the end of the trials. This information was reviewed and the guidelines were amended accordingly before being rolled out. The guidelines have been in use for over 12 months and have provided the benchmark against which to audit practice, and have resulted in key performance improvements such as an increase in client review rates and a rise in the feedback response rate from clients, with a noticeable shift in the comments about the brokered support worker to acknowledging the role of their case manager. Formalising informal supports for those clients that lived alone also increased, which means these people are less reliant on services and there is a reduced risk of social isolation. PMID:24598416

    2004-05-01

    In this month's column, case studies are touted as an effective means of promoting critical thinking skills. Most of them are discipline specific, certainly. But they all grapple with the essence of critical thinking--asking for evidence--developing a habit of mind that should permeate everyday life. Specifically, the virtues of the "Interrupted Case Method" technique is extolled because through this method, students struggle with a real research problem and challenge each other and the data. Most importantly, they see different groups offering alternative approaches to the problem, and they see model behavior from the experts.

    Christensen, Eric; Jaffke, Patrick

    2013-01-01

    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 ...

    2006-10-15

    Full Text Available The organization of biotechnology differs across countries. The structure of the industry, the academia, and the links between these two sectors vary according to which country is studied. Biotechnology is organized in Venezuela mainly around the research done by special research and development uni [...] ts at national universities. The paper describes some of these units in order to shed light about their performance. Two economic approaches are used to explain the academic production of these biotech research organizations: the technological and organizational approaches. A case study methodology is used in this research. The results can be summarized as: The percentage of researchers who are doctors is less than seventy percent in each research and development unit, funding source comes basically from the Venezuelan government, strategic alliances are mainly formed between universities, performance of research and development units is mostly oriented to research but not to development . The main conclusion of this paper is that the research and development organizations are only carrying out the research function because (i) the low number of doctors, (ii) the few number of strategic alliances with the private sector and (iii) the form the research and development units finance themselves.

    The implementation of the EU REACH regulation will most probably promote substitution within sectors handling a lot of different chemicals such as the printing industry. With the aim of being at the cutting edge of this development, the Danish printing industry started up a substitution project in 2006. A major part of the work has been mapping the presence of chemicals, which are the potential candidates for substitution (e.g., PBT, CMR, vPvB, EDS). The mapping comprises a combination of a literature study and an investigation of the actual (2007) presence of candidate substances at 15 Danish printing houses including the examination of almost 900 MSDSs (i.e., products). Furthermore, a focused search in the Danish Product Register has been included. More than 200 of the mapped substances are candidates for substitution according to Danish legislation (List of Undesirable Substances) and about 60 of these substances fulfill one or more of the criteria (e.g., CMR, EDS) for the REACH Annex XIV candidate list (Authorisation List). This case study presents the results of the mapping of chemical substitution candidates some of which may be relevant regarding accumulation of additives/impurities in globally recycled paper.

    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.

    In the last ten years there has been a proliferation of regional building rating systems across the Middle East (ME). Most those emerging rating systems and labels emulate the British and American rating systems BREEAM and LEED that emerged in industrial countries context with an impact reduction paradigm. Thus they are neglecting the local historic, climatic, economic, technological, cultural and social context of the ME. This paper presents a case study of a recently constructed eco-lodge,...

    BACKGROUND: Each year, thousands of cases of uncomplicated malaria are imported into Europe by travellers. Atovaquone-proguanil (AP) has been one of the first-line regimens used in France for uncomplicated malaria for almost ten years. While AP's efficacy and tolerance were evaluated in several trials, its use in "real life" conditions has never been described. This study aimed to describe outcome and tolerance after AP treatment in a large cohort of travellers returning from endemic areas. M...

  5. On misunderstandings in connection with case-studies

    DEFF Research Database (Denmark)

    Flyvbjerg, Bent

    2005-01-01

    This article examines five common misunderstandings about case-study research: (1) Theoretical knowledge is more valuable than practical knowledge; (2) One cannot generalize from a single case, therefore the single case study cannot contribute to scientific development; (3) The case study is most useful for generating hypotheses, while other methods aremore suitable for hypotheses testing and theory building; (4) The case study contains a bias toward verification; and (5) It is often difficult to summarize specific case studies. The article explains and corrects these misunderstandings one by one and concludes with the Kuhnian insight that a scientific discipline without a large number of thoroughly executed case studies is a discipline without systematic production of exemplars, and that a discipline without exemplars is an ineffective one. Social science may be strengthened by the execution of more good case studies.

  8. Positive effect of removal of subchondral bone plate for cemented acetabular component fixation in total hip arthroplasty: a randomised RSA study with ten-year follow-up.

    Science.gov (United States)

    Flivik, G; Kristiansson, I; Ryd, L

    2015-01-01

    We hypothesised that the removal of the subchondral bone plate (SCBP) for cemented acetabular component fixation in total hip arthroplasty (THA) offers advantages over retention by improving the cement-bone interface, without jeopardising implant stability. We have previously published two-year follow-up data of a randomised controlled trial (RCT), in which 50 patients with primary osteoarthritis were randomised to either retention or removal of the SCBP. The mean age of the retention group (n = 25, 13 males) was 70.0 years (sd 6.8). The mean age in the removal group (n = 25, 16 males) was 70.3 years (sd 7.9). Now we have followed up the patients at six (retention group, n = 21; removal group, n = 20) and ten years (retention group: n = 17, removal group: n = 18), administering clinical outcome questionnaires and radiostereometric analysis (RSA), and determining the presence of radiolucent lines (RLLs) on conventional radiographs. RSA demonstrated similar translation and rotation patterns up to six years. Between six and ten years, proximal acetabular component migration and changes of inclination were larger in the retention group, although the mean differences did not reach statistical significance. Differences in migration were driven by two patients in the SCBP retention group with extensive migration versus none in the SCBP removal group. The significant difference (p < 0.001) in the development of radiolucent lines in the retention group, previously observed at two years, increased even further during the course of follow-up (p < 0.001). While recognising SCBP removal is a more demanding technique, we conclude that, wherever possible, the SCBP should be removed to improve the cement-bone interface in order to maximise acetabular component stability and longevity.

    2010-03-01

    Full Text Available Applied research in a public health setting seeks to provide professionals with insights and knowledge into complex environmental issues to guide actions that reduce inequalities and improve health. We describe ten environmental case studies that explore the public perception of health risk. We employed logical analysis of components of each case study and comparative information to generate new evidence. The findings highlight how concerns about environmental issues measurably affect people’s wellbeing and led to the development of new understanding about the benefits of taking an earlier and more inclusive approach to risk communication that can now be tested further.

  10. Comparative economic analysis: Anaerobic digester case study

    International Nuclear Information System (INIS)

    An economic guide is developed to assess the value of anaerobic digesters used on dairy farms. Two varieties of anaerobic digesters, a conventional mixed-tank mesophilic and an innovative earthen psychrophilic, are comparatively evaluated using a cost-effectiveness index. The two case study examples are also evaluated using three other investment merit statistics: simple payback period, net present value, and internal rate of return. Life-cycle savings are estimated for both varieties, with sensitivities considered for investment risk. The conclusion is that an earthen psychrophilic digester can have a significant economic advantage over a mixed-tank mesophilic digester because of lower capital cost and reduced operation and maintenance expenses. Because of this economic advantage, additional projects are being conducted in North Carolina to increase the rate of biogas utilization. The initial step includes using biogas for milk cooling at the dairy farm where the existing psychrophilic digester is located. Further, a new project is being initiated for electricity production with thermal reclaim at a swine operation

    Full Text Available To what extent and in what arenas do collaborating musicians need to understand what they are doing in the same way? Two experienced jazz musicians who had never previously played together played three improvisations on a jazz standard (“It Could Happen to You” on either side of a visual barrier. They were then immediately interviewed separately about the performances, their musical intentions, and their judgments of their partner’s musical intentions, both from memory and prompted with the audiorecordings of the performances. Statements from both (audiorecorded interviews as well as statements from an expert listener were extracted and anonymized. Two months later, the performers listened to the recordings and rated the extent to which they endorsed each statement. Performers endorsed statements they themselves had generated more often than statements by their performing partner and the expert listener; their overall level of agreement with each other was greater than chance but moderate to low, with disagreements about the quality of one of the performances and about who was responsible for it. The quality of the performances combined with the disparities in agreement suggest that, at least in this case study, fully shared understanding of what happened is not essential for successful improvisation. The fact that the performers endorsed an expert listener’s statements more than their partner’s argues against a simple notion that performers’ interpretations are always privileged relative to an outsider’s.

  13. Environmental injustice: case studies from the South

    International Nuclear Information System (INIS)

    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

  14. High Penetration Photovoltaic Case Study Report

    2013-01-01

    Technical concerns with integrating higher penetrations of photovoltaic (PV) systems include grid stability, voltage regulation, power quality (voltage rise, sags, flicker, and frequency fluctuations), and protection and coordination. The current utility grid was designed to accommodate power flows from the central generation source to the transmission system and eventually to the distribution feeders. At the distribution level, the system was designed to carry power from the substation toward the load. Renewable distributed generation, particularly solar PV, provides power at the distribution level challenging this classical paradigm. As these resources become more commonplace the nature of the distribution network and its operation is changing to handle power flow in both directions. This report is focused on large PV installations in which penetration is significantly greater than 15% of maximum daytime feeder load. These case studies are intended to demonstrate success stories with integration of large PV plants at the distribution level as well as some of the solutions used by the utility to ensure safe, reliable operation of both the PV system and the distribution network.

    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.

  8. Brazilian oil spills chemical characterization : case studies

    International Nuclear Information System (INIS)

    The Petrobras Research Centre has been active in responding to some significant oil spills in Brazil in the past decade. The centre has characterized spilled oil, monitored the affected ecosystems and determined the fate of oil in the environment. This paper described the use of some advanced chemical analytical techniques used in Brazilian oil spill studies to determine fractions and individual petroleum hydrocarbons in water, groundwater, sediment, sand, fish and the spilled oil itself. Some of the most recent oil spill cases were discussed in terms of chemical characterization of the spilled oil and the environmental samples from different matrices of the affected ecosystems for determining the fate of the oil in the environment and to assess environmental damage. In particular, methods such as gas chromatography/flame ionization detector, P and T/GC/PID and gas chromatography/mass spectrometry have been used to examine crude and fuel oil spills in Guanabara Bay, Barigui and Iguassu Rivers, and the Sao Sebastiao Channel. The chemical analytical methods are used to determine total petroleum hydrocarbons, n-alkanes, isoprenoids, unresolved complex mixtures, volatile monoaromatic compounds such as BTEX (benzene, toluene, ethylbenzene and xylenes), as well as parent and alkylated homologues polycyclic aromatic hydrocarbons (PAH) and terpanes and steranes. Acute ecotoxicity data for water and sediment samples was also included. It was determined that with certain limitaIt was determined that with certain limitations, PAH ratios can help determine the origin of hydrocarbons as being either petrogenic or pyrolytic. However, alkylated PAH homologues and parent compounds such as dibenzothiophene and perylene give more precise interpretation of the data. 30 refs., 9 tabs., 11 figs

    Carolan-Olah, Mary

    2013-05-16

    BACKGROUND:: stress in pregnancy is common and impacts negatively on women, infants and families. A number of factors contribute to high levels of stress in pregnancy, including financial concerns, marital discord, low support systems and low socio-economic status. OBJECTIVES:: the aim of this study was to evaluate stress anxiety levels and depressive symptoms among low risk women in an area in Ireland that was particularly impacted by the 2008 economic crisis. DESIGN:: a quantitative descriptive cross-sectional design was used. Data were collected using the Edinburgh Postnatal Depression Scale (EPDS), the Perceived Stress Scale and the State Trait Anxiety Inventory (STAI). Data was collected at a single time during the second trimester. SETTING:: this paper reports a case study of one maternity service in Ireland. Participants included low risk pregnant women who were attending the hospital clinic for routine antenatal care. RESULTS:: of 150 questionnaires distributed, 74 completed questionnaires were returned indicating a 49.3% return rate. Findings indicated high levels of stress, anxiety and depressive symptomatology among participants. There were no significant difference in mean EPDS score for different age groups (F4,69=2.48, P=0.052), living arrangements (F4,68=0.90, P=0.5) or usual occupation (F4,69=1.45, P=0.2). A score of ?12 was taken as indicative of probable antenatal depression and 86.5% of participants responded with a score of 12 or above. PSS scores were also high and more than three quarters of respondents scored ?15 (75.6%) and more than a third had scores ?20 (35.1%), out of a total score of 40. There was a significant difference in mean PSS score between the different age groups (F4,69=3.60, P=0.010) but not for living arrangements or usual occupation. A STAI score of ?39 was taken as indicative of antenatal anxiety, and 74.3% of participants responded with a score of 39 or above. There were no significant differences in mean STAI score between the different age groups (F4,68=1.68, P=0.16), living arrangements (F4,67=2.30, P=0.068) or usual occupations (F4,68=1.25, P=0.3). KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE:: this study found high levels of antenatal stress, anxiety, and depressive symptoms in a low risk pregnant population, in an economically impacted region in Ireland. These findings have implications for fetal development and maternal health during pregnancy and in the post partum. Further studies are important to confirm rates and should be conducted over a longer time frame with data collected at more than one point in time, such as mid and late pregnancy. If findings are confirmed, early recognition and treatment of stress, anxiety and depressive symptoms is important to ameliorate some of the harmful effects of these conditions.

    Remote sensing methodology developed for the Nationwide Forestry Applications Program utilize computer data processing procedures for performing inventories from satellite imagery. The Ten-Ecosystem Study (TES) was developed to test the processing procedures in an intermediate-sized application study. The results of TES indicate that LANDSAT multispectral imagery and associated automatic data processing techniques can be used to distinguish softwood, hardwood, grassland, and water and make inventory of these classes with an accuracy of 70 percent or better. The technical problems encountered during the TES and the solutions and insights to these problems are discussed. The TES experience is useful in planning subsequent inventories utilizing remote sensing technology.

    Two 1500 foot temperature gradient holes and two deep exploratory wells were drilled and tested. Hydrologic-hydrochemical, shallow temperature survey, structural-tectonic, petrologic alteration, and solid-sample geochemistry studies were completed. Eighteen miles of high resolution reflection seismic data were gathered over the area. The study indicates that a geothermal regime with temperatures greater than 400/sup 0/F may exist at a depth of approximately 7500' to 10,000' over an area more than ten miles in length.

    Soil is a non-renewable resource with fundamental functions like filtering (e.g. water), storing (e.g. carbon), transforming (e.g. nutrients) and buffering (e.g. contamination). Degradation of soils is meanwhile not only to scientists a well known fact, also decision makers in politics have accepted this as a serious problem for several environmental aspects. National and international authorities have already worked out preservation and restoration strategies for soil degradation, though it is still work of active research how to put these strategies into real practice. But common to all strategies the description of soil state and dynamics is required as a base step. This includes collecting information from soils with methods ranging from direct soil sampling to remote applications. In an intermediate scale mobile geophysical methods are applied with the advantage of fast working progress but disadvantage of site specific calibration and interpretation issues. In the framework of the iSOIL project we present here some case studies for soil mapping performed using multiple geophysical methods. We will present examples of combined field measurements with EMI-, GPR-, magnetic and gammaspectrometric techniques carried out with the mobile multi-sensor-system of Kiel University (GER). Depending on soil type and actual environmental conditions, different methods show a different quality of information. With application of diverse methods we want to figure out, which methods or combination of methods will give the most reliable information concerning soil state and properties. To investigate the influence of varying material we performed mapping campaigns on field sites with sandy, loamy and loessy soils. Classification of measured or derived attributes show not only the lateral variability but also gives hints to a variation in the vertical distribution of soil material. For all soils of course soil water content can be a critical factor concerning a succesful application of geophysical methods, e.g. GPR on wet loessy soils will result in a high attenuation of signals. Furthermore, with this knowledge we support the development of geophysical pedo-transfer-functions, i.e. the link between geophysical to soil parameters, which is active researched in another work package of the iSOIL project.

    Full Text Available Neoplasias do ânus correspondem de 2 a 4% dos tumores de intestino grosso, sendo predominante nas sétima e oitava décadas. A maior prevalência é em gênero feminino, com proporção de 3:1. O aumento da prevalência na população nos últimos anos provavelmente está relacionado ao número maior de pessoas [...] com doenças sexualmente transmissíveis, principalmente o papilomavírus humano (tipos 16 e 18, mais comumente) e/ou o vírus da imunodeficiência humana. O diagnóstico é feito a partir de achados clínicos somados ao exame anatomopatológico. O tratamento de escolha baseia-se na radioquimioterapia, sendo a cirurgia de resgate com amputação abdominoperineal utilizada para casos de recidiva ou persistência. Foi feito um estudo observacional longitudinal retrospectivo e prospectivo, com 11 pacientes diagnosticados com neoplasia anal no período de 2004 a 2010. Seis (54,5%) eram do gênero feminino e 5 (45,5%) do masculino. O pico de incidência foi em sexta década, com média de idade de 54,45 anos. O tipo histológico mais encontrado foi o carcinoma epidermoide (72,7%), sendo o moderadamente diferenciado o mais frequente grau de diferenciação. A quimioterapia associada à radioterapia foi instituída em 81,9% dos pacientes, sendo necessária a cirurgia de amputação abdominoperineal como terapia de resgate em 18,2% dos pacientes. Abstract in english Anus neoplasm accounts for 2 to 4% of colorectal tumors, being more prevalent around the seventh and the eighth decades. Females are mostly affected, and the ratio is 3:1. Its increased prevalence amongst the population in the past years is probably related to the higher number of people that are af [...] fected by sexually transmitted diseases, mainly human papillomavirus (types 16 and 18, mostly) and/or the human immunodeficiency virus. Diagnosis is based on clinical findings and anatomopathological tests. The treatment of choice is radiochemotherapy, and the rescue surgery with abdominoperineal resection is used for recurrence and persistence cases. A retrospective and prospective longitudinal observational study was performed with 11 patients diagnosed with anal neoplasm from 2004 to 2010. Six (54.5%) were females and five (45.5%) were males. The incidence was higher in the sixth decade, at the mean age of 54.45 years. The most frequent histological type observed was the epidermoid carcinoma, and the most frequent cell differentiation type was the moderately differentiated. Chemotharapy associated with radiotherapy was used in 81.9% of the patients, and abdominoperineal resection was necessary as a rescue surgery in 18.2% of the patients.

    Abstract: This article is a presentation of a brief cultural glossary of Northern Sotho cooking terms. The glossary is mainly composed of names for utensils and ingredients, and action words for the processes involved in the preparation of cultural dishes. It also contains names of dishes tied to some idiomatic expressions in a way eliciting cultural experiences that can lead to an under-standing of indigenous knowledge systems. The article seeks to explore ways of capturing cultural glossaries to feed into the national dictionary corpora by using a case-study approach to investigate the processes that led to the generation of this specific school-based project. A number of issues that surfaced in this project, can possibly serve as models for the collection of authentic glossaries that can support dictionary making in African languages.

    Full Text Available DBMS systems and databases in chemistry, whether for retrieval information or retrieval strategy, are usually limited by their procedural reasoning tools. The limitations of usual systems are often caused by a lack of flexibility due to rigid structuration of the search space, the choice of given logic and very often, the fuzzy nature of some of the basic state of space blocks. We are currently investigating the power of analogical search and retrieval tools with an eye to developing a flexible system through the case memory strategy and the use of case memory storing potential similar features chosen by users.

    In this interdisciplinary case, students meet Josie, the main character, who suffers from a variety of symptoms. Students must grapple with the conflicting data presented, which ultimately leads them to a diagnosis of either porphyria or schizophrenia. This case can be used in many ways depending on the focus of the course and the instructor. In its simplest form, it can be used to develop content-specific knowledge on the genetic illness porphyria and/or the psychological illness schizophrenia. In an interdisciplinary context, it can be used as a way to discuss complex modes of inheritance and types of confounding issues a genetic counselor, social worker, psychiatrist, or psychologist might face when trying to sort through a complex family history to develop a pedigree or genogram. The case has been used successfully with majors and non-majors in psychology, biology, and genetics. Optional extensions to the case provide for reflection on the theme of "science in society" and how the perception of disease has changed over time.

    Full Text Available Background: Mucocele is one of the most common benign soft tissue tumor present in the oral cavity. They are of two types - one is extravasation and second one is retention type but the majority are extravasation type. Aims: The objective is to determine various factors related to mucocele such as role of trauma due to nearby teeth, recurrence, duration, and to find out whether there is any role of psychological stress which initiates trauma like lip or cheek biting. Materials and Methods: 36 cases of mucocele diagnosed at the Department of the Oral Pathology, Govt. Dental College and Hospital, Ahmedabad, between 2004 and 2008 were reviewed. The clinical data were recorded and histopathologic diagnosis was made. Statistical Analysis Used: Data analysis tool, Microsoft Office Excel 2007. Results: A diagnosis of mucocele was established in 36 cases with male-to-female ratio of 1.77:1. Most common type was extravasation in 30 (83.33% cases. The peak age of occurrence was between 1st and 3rd decade. Lateral side of the lower labial mucosa was the most affected site in 34 (94.44% cases. The history of trauma appeared the major etiological factor seen in 28 (77.77% cases. Conclusion: We conclude that there was male predominance and they were more affected in 2nd and 3rd decade. The lateral side of lower labial mucosa was the commonest site and the trauma due to teeth or lip biting was the major etiological factor for the occurrence of the mucocele. The article highlights role of psychological stress in occurrence of mucocele. The reader should understand the importance of histopathology examination and should try to control the psychological stress in such mucocele patients.

Patients and methods Prospective multicentre case-control study. Between 2005 and 2008, 110 NF-1 adults having two or more SC-NFs were individually matched for age, sex and hospital with 110 controls who had no SC-NF. Patients underwent standardized MRI of the spinal cord, nerve roots and sciatic nerves and an electrophysiological study. Analyses used adjusted multinomial logistic regression (ORa to estimate the risk of the presence of internal neurofibromas or peripheral neuropathies associated with patients presented 2 to 9 SC-NFs, at least 10 SC-NFs as compared to patients without any (referential category. Results Cases had a mean age of 41 (± 13 years; 85 (80% had two to nine SC-NFs and 21 (19% at least ten SC-NFs. SC-NFs were more strongly associated with internal neurofibromas in patients with ten or more SC-NFs than in patients with fewer NF-SCs (e.g., sciatic nerve, aOR = 29.1 [8.5 to 100] vs. 4.3 [2.1 to 9.0]. The association with SC-NFs was stronger for diffuse, intradural, and > 3 cm internal neurofibromas than with other internal neurofibromas. Axonal neuropathy with slowed conduction velocities (SCV was more strongly associated with having at least ten SC-NFs (aOR = 29.9, 5.5 to 162.3 than with having fewer SC-NFs (aOR = 4.4, 0.9 to 22.0. Bivariate analyses showed that the association between axonal neuropathy with SCV and sciatic neurofibromas was mediated by the association between SC-NFs and sciatic neurofibromas. Conclusion The at-risk phenotype of NF-1 patients (i.e. NF-1 patients with SC-NFs is ascribable to associations linking SC-NFs to internal neurofibromas at risk for malignant transformation and to axonal neuropathies with slowed conduction velocities. Axonal neuropathies with SCV are particularly common in patients with at least ten SC-NFs. Registration details ORPHA86301

    The celebrated expectation-maximization (EM) algorithm is one of the most widely used optimization methods in statistics. In recent years it has been realized that EM algorithm is a special case of the more general minorization-maximization (MM) principle. Both algorithms creates a surrogate function in the first (E or M) step that is maximized in the second M step. This two step process always drives the objective function uphill and is iterated until the parameters converge. The two algorit...

    This case study is based on another case in our collection, The 2000-Meter Row: A Case in Homeostasis, which emphasizes the metabolic, respiratory, and cardiac responses of a young athlete competing in a championship rowing event. In this modified version, the same event is viewed in a new light to explore the psychological ramifications of the stressful sports competition. The case was developed for a mixed undergraduate-graduate course in sport psychology.

  15. Orbital dermoid and epidermoid cysts: Case study

    Full Text Available Introduction. Dermoid and epidermoid cysts of the orbit belong to choristomas, tumours that originate from the aberrant primordial tissue. Clinically, they manifest as cystic movable formations mostly localized in the upper temporal quadrant of the orbit. They are described as both superficial and deep formations with most frequently slow intermittent growth. Apart from aesthetic effects, during their growth, dermoid and epidermoid cysts can cause disturbances in the eye motility, and in rare cases, also an optical nerve compression syndrome. Case Outline. In this paper, we described a child with a congenital orbital dermoid cyst localized in the upper-nasal quadrant that was showing signs of a gradual enlargement and progression. The computerized tomography revealed a cyst of 1.5-2.0 cm in size. At the Maxillofacial Surgery Hospital in Niš, the dermoid cyst was extirpated in toto after orbitotomy performed by superciliary approach. Postoperative course was uneventful, without inflammation signs, and after two weeks excellent functional and aesthetic effects were achieved. Conclusion. Before the decision to treat the dermoid and epidermoid cysts operatively, a detailed diagnostic procedure was necessary to be done in order to locate the cyst precisely and determine its size and possible propagation into the surrounding periorbital structures. Apart from cosmetic indications, operative procedures are recommended in the case of cysts with constant progressions, which cause the pressure to the eye lobe, lead to motility disturbances and indirectly compress the optical nerve and branches of the cranial nerves III, IV and VI.

  16. Ten questions on nuclear wastes

    International Nuclear Information System (INIS)

    The authors give explanations and answers to ten issues related to nuclear wastes: when a radioactive material becomes a waste, how radioactive wastes are classified and particularly nuclear wastes in France, what are the risks associated with radioactive wastes, whether the present management of radioactive wastes is well controlled in France, which wastes are raising actual problems and what are the solutions, whether amounts and radio-toxicity of wastes can be reduced, whether all long life radionuclides or part of them can be transmuted, whether geologic storage of final wastes is inescapable, whether radioactive material can be warehoused over long durations, and how the information on radioactive waste management is organised

    This report documents the authors work as an expert team advising the US Department of Energy on modes of inadvertent intrusion over the next 10,000 years into the Waste Isolation Pilot Project (WIPP) nuclear waste repository. Credible types of potential future accidental intrusion into the WIPP are estimated as a basis for creating warning markers to prevent inadvertent intrusion. A six-step process is used to structure possible scenarios for such intrusion, and it is concluded that the probability of inadvertent intrusion into the WIPP repository over the next ten thousand years lies between one and twenty-five percent. 3 figs., 5 tabs

    2010-09-15

    Access and affordability to energy services determine the state of energy poverty; however, there is no widely applicable definition of energy poverty and no universal set of measures for its eradication exists. This paper offers a new definition and possible solution for decrease, and eventually eradication, of energy poverty for the specific case of Tajikistan. As eradication of energy poverty needs to go in hand with nature preservation and economic development, authors provide possible approach to decrease of energy poverty in Tajikistan while simultaneously preserving nature and boosting the local economy.

    We report a case of osteitis in a 46-year-old patient, caused by Pseudomonas stutzeri following an open fracture of the left femur. The patient was treated with 1g ceftazidime every 8 hours for two weeks combined with 160 mg/day of amikacin for 10 days. A second-line ofloxacin oral treatment at 400 mg/day was then given during 4 weeks. Surgical treatment consisted in debridement of the fracture region. Sterilization of the fracture region led to an osteosynthesis by blade plate and bone graft. The result was favorable. PMID:17010550

    Full Text Available I offer an integrated theory of the meaning of only in which the prejacent, while not presupposed, is both entailed and backgrounded, hence tends to project (following a general proposal about projection due to Simons et al. 2010.

    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. Ten years of nuclear power

    International Nuclear Information System (INIS)

    Ten years have elapsed since the world's first nuclear power station began to supply electricity in Russia, and this in turn marked the end of a twelve year stage following the first controlled nuclear chain reaction at Chicago. These periods mark major stages in the development of atomic energy from the realm of abstract ideas to that of everyday industrial application. They followed a period of fundamental research and laboratory work, culminating in Enrico Fermi's demonstration of a system whereby the forces of the atom could be brought under control. Then it was necessary to find ways and means of using the chain reaction for practical purposes and on an industrial scale. And after this had been shown in 1954 to be technically possible, it had still to be developed into an economic process. The nuclear power station has proved itself from the technical and engineering standpoint. The third phase of development has been to bring it to the stage of being economically competitive with alternative sources of energy, and it would appear that we are now reaching that goal - though more slowly than had been envisaged ten years ago

    Three cases with hypersensitivity pneumonitis were studied with Tl-201 scintigraphy, perfusion lung scan and other clinical findings. Major symptoms and signs were fever and cough in 3 cases, exertional dyspnea in 2, sputum in 1 and moist rales in 3. Laboratory data showed elevated ESR, hyper ..gamma..-globulinemia in 3 cases, leukocytosis in 2, eosinophilia in 3, positive CRP in 2 and positive RA test in 1. Chest x-ray film revealed diffuse scattered reticulonodular shadows in 3 cases and patchy ones in 2. Abnormalities in the pulmonary function tests were decreased vital capacity and Pa sub(o2) in 3 cases, increased residual volume and decreased diffusion capacity in 2, decreased V50 and V25 in flow volume curve in 1. Precipitating antibodies against Sitophilus granarius, Thermoactinomyces vulgaris, Micropolyspola faeni, Aspergillus fumigatus and budgerigar serum were detected. Tl-201 scintigram showed diffuse marked uptake of Tl-201 in both lungs of 2 cases at acute stage and moderate in 2 cases in remission when abnormal shadows on chest x-ray film had been disappeared. Two cases in remission showed slight positive or negative results, but in 1 case moderate uptake was yet observed after 11 months. Positive visualization of right ventricle was demonstrated in 2 cases. Perfusion lung scintigram showed decreased perfusion in 3 cases. Each of 2 cases in acute stage and in remission showed slightly decreased perfusion and one case in admission showed a moderate decrease and still showed a slight decrease after 9 months.

    Strano, Emanuele; Cardillo, Alessio; Costa, Luciano Da Fontoura; Porta, Sergio; Latora, Vito

    2012-01-01

    We compare the structural properties of the street networks of ten different European cities using their primal representation. We investigate the properties of the geometry of the networks and a set of centrality measures highlighting differences and similarities among cases. In particular, we found that cities share structural similarities due to their quasi planarity but that there are also several distinctive geometrical proprieties. A Principal Component Analysis is also performed on the distributions of centralities and their respective moments, which is used to find distinctive characteristics by which we can classify cities into families. We believe that, beyond the improvement of the empirical knowledge on streets network proprieties, our findings can open new perspectives in the scientific relation between city planning and complex networks, stimulating the debate on the effectiveness of the set of knowledge that statistical physics can contribute for city planning and urban morphology studies.

  20. Mobile and Social: Ten Best Practices for Designing Mobile Applications

    Directory of Open Access Journals (Sweden)

    2010-01-01

    Full Text Available This paper gives ten best practices for designing mobile applications that have social-networking functions. The need for such an approach is given by the rapid growth in impor-tance of both social networks and mobile applications. In order to make it easy to follow where the best practices come from, the paper starts with a look at why social networks are more than just a buzz word and at how the field of mobile applications is evolving. It also shows how and why the two fields go together so well. To further make the point, there is a case study of four interesting mobile applications that are textbooks examples of successful applications. The best practices are based on research done for this article and on the extensive knowledge of the author.
