    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.

    In 1990, DOE initiated a nationwide evaluation of its Weatherization Program, with assistance from Oak Ridge National Laboratory and an advisory group of 40 weatherization professionals, program managers, and researchers. The evaluation is comprised of three impact studies covering the Program`s major market segments: Single-family homes, mobile homes, and dwellings in small (2 to 4-unit) multifamily buildings (the Single-Family Study), Single-family homes heated primarily with fuel oil (the Fuel-Oil Study), and Dwellings in buildings with five or more units (the Multifamily Study). The Single-Family Study, the subject of this report, is a critical part of this coordinated evaluation effort. Its focus on single-family dwellings, mobile homes, and dwellings in small multifamily buildings covers 83% of the income-eligible population and 96% of the dwellings weatherized during Program Year 1989. The first phase of the Single-Family Study involved the analysis of a massive data base of information collected from 368 local weatherization agencies and 543 electric and gas utilities. This analysis resulted in energy-saving and cost-effectiveness estimates for the Weatherization Program and the identification of a set of ten high-performing agencies located throughout the country. The second phase, which is the subject of this report, involves a ``process`` evaluation of these ten high performers, aimed at identifying those weatherization practices that explain their documented success.

    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.

  9. A clinical study on ten cases of superior mesenteric arterial occulusion

    International Nuclear Information System (INIS)

    A total of 10 cases of acute superior mesenteric arterial occulusion (SMAO) treated in our department in a previous 11-year period were divided into the survival (n=4) and death (n=6) groups and studied for the diagnosis, treatment, and postoperative management. An averaged age of them was as high as 81 years. All the patients had some cardiovascular disorders as underlying diseases, and seven patients of them had atrial fibrillation. The time from the onset of SMAO to the treatment ranged from 4 to 96 hours, in that no significant difference was noted between the survival and death groups. Contrast enhanced abdominal CT was conducted preoperatively in all the patients. It was retrospectively considered that preoperative diagnosis had to be made by the CT scans in eight of them who had developed occulusion at the center of the superior mesenteric artery. Except one patient who could be treated by interventional radiology (IVR) using a balloon-tip catheter, the remaining nine patients underwent laparotomy and six out of the nine patients underwent the resection of massive intestines. Seven patients overcame postoperative acute phase, however, only four of them were able to recover their social activities. In order to improve the prognosis of the disease, we are required not only to avoid massive intestinal resection by making early diagnosis, but also to conduct long-term postoperative intensive therapies including those for underlying diseases as well as prevention of recurrence and nutritional management.

    Intramedullary schwannomas are very rare. Most studies on intramedullary schwannomas have been case reports with literature reviews. This study presented a surgical series of ten patients with histologically proven intramedullary schwannomas. From 1995 to 2010, ten patients (2.7 %) presented with intramedullary schwannomas out of 365 patients with spinal schwannomas. Their clinical and radiological findings and operative records were reviewed. There were 6 female and 4 male patients with a mean age of 45.5 years. The mean follow-up period was 75.7 months. Three tumors were located in the cervical spine and 7 were located in the thoracic spine. Intraoperatively, the tumor was connected with the dorsal rootlet in 4 cases and with the ventral rootlet in 1 case. Gross total resection (GTR) of the tumor with a well-demarcated dissection plane was achieved in 8 cases and subtotal resection (STR) was achieved in 2 cases. The current status of all the patients was improved compared to the preoperative presentation at last follow-up and the symptoms present before the surgery were improved in all the cases at last follow-up. The postoperative follow-up magnetic resonance imaging showed no recurrence in the 8 GTR cases during the follow-up period of 83.5 months on average. No interval change in residual tumors was observed in the 2 STR cases (45- and 55-month follow-up periods). Intramedullary schwannomas are amenable to surgery. It is possible to achieve GTR of intramedullary schwannomas that have a well-demarcated dissection plane. Additionally, a good clinical outcome after GTR can be expected. PMID:23447118

  18. 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.

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.

    Full Text Available Fuel market is facing political, economic, social and environmental problems that are fuzzing the future of fossil energy sources and in face of these facts, countries are looking for hybrid and electric vehicles as part of solution in transportation sector due to the fact of electric vehicles use few or no fossil fuel. The objective in this article was to identify options until 2020 to introduce electric vehicle in the urban traffic of São Paulo city and to develop this study the method of literature review in secondary sources was used to present electric vehicle technologies and to identify parameters that were assessed through morphological analysis technique. In morphological analysis, sets of values were defined by the author for these parameters, possible combinations were structured, clearly impractical deployment options before 2020 were discarded and some viable solutions were analyzed in details. These analyses concluded that there are viable options for actual days in São Paulo city, but important requirements regarding technology, politic, market, infrastructure and innovation in products and services still need to be addressed and it is the main reason of electric vehicle remain unnoticed by consumers as an viable option. The challenges are great and the actors who are willing to solve them will find a promising market to explore.

    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. In this study group, 74% of the patients recovered, 16.3% died and 16.5% relapsed.Conclusions: The prevalence of FAB-L1 and pre-B cell cases in this study is greater than a previous study, while the prevalence of FAB-L2 and early pre-B cell cases is less than that of the previous study.

    Malignant fibrous histiocytomas (MFH) are believed to originate from histiocytes and are composed of malignant cells with spindle or round shapes. We evaluated ten MFH of the soft tissues by plain roentgenograms, computed tomography (CT), and angiography and subdivided them into four grades of anaplasia and five predominant histologic variants. The variants of MFH demonstrated different vascular patterns. The extension of the lesions could be determinded by CT and angiography. CT is the method of choice in the assessment of size and extent of MFH of the soft tissues. When intra-arterial chemotherapy is indicated the angiograms obtained at each catheter placement may substitute CT in follow-up studies obviating additional diagnostic procedures.

  14. [Treatment of Poland syndrome thorax deformity with the lipomodeling technique: about ten cases].

    The correct management, with the classic techniques, of the thoracic deformity in Poland's syndrome is difficult, with often insatisfactory results. The current surgical treatment involves the use of prothetic material and/or different flaps with their own complications and scares. The experience of our team with fat grafting (we named lipomodeling) in breast reconstruction helped us to propose the correction of the thoracic and mammary deformity by repeated fat transfer sessions. Fat grafting is commonly used in our team since 1998 in various indication of breast surgery. We reviewed retrospectively our ten first cases of thoracic deformity in Poland's syndrome treated with only fat grafting. Patients had repeated procedures until obtaining a satisfactory result. The fat was harvested from the thigh, buttocks, and abdomen. There were young patients with a mean age of 16years old (from 12 to 24). The mean follow-up was 51months. An average of 2.9 procedures (1 to 5) with 255cm(3) of fat injection at each procedure was needed to obtain symetry. Hundred percent of the patients were satisfied. No complication was noted. As reported, the reconstruction of the thoracic deformity and the mammary shape can be obtained by fat grafting. The absence of a flap donor site sequelae and the absence an implant allow this technique to be simple, reproductible, and without great complication. These criteria match well the surgical management of this deformity, which is mainly aesthetic. Moreover, the secondary benefit of liposuction of disgracious steatomery helps the acceptance of the procedure. Therefore in our hands, fat grafting to the breast (lipomodeling) is now our first choice treatment in thoracic Poland syndrome deformity. Given the rarity of this syndrome, we recommend a treatment by an operator who makes the learning curve of lipomodeling, and who often deals with Poland syndrome. PMID:23153632

    Cytogenetic study of five biphasic and five monophasic synovial sarcomas revealed the specific abnormality t(X;18) (p11;q11) in eight cases and t(X;15;18) (p11;q15;q11) and t(X;7) (q11-12;q32) in one case each. Additional, secondary aberrations were present in eight of these tumors. By combining our data with information on previously published cytogenetically abnormal synovial sarcomas, we were able to evaluate 32 tumor samples from 29 patients. The modal chromosome number was pseudodiploid or near diploid in 26 of the 32 tumors. A t(X;18) was present in 21 of 29 cases (72%). Complex translocations involving chromosomes X and 18 and another autosome were present in five cases, and one displayed a t(5;18). There was no visible rearrangement of chromosome bands Xp11 or 18q11 in only 2 of the 32 synovial sarcomas. Half of the primary tumors (6 of 12) had the X;18-translocation as the sole abnormality. Of the remaining 20 specimens from recurrent or metastatic tumors (in three cases two tumors could be analyzed), only one had t(X;18) as the sole change. The secondary aberrations in cases exhibiting clonal evolution were also generally more extensive in the metastatic and recurrent than in the primary sarcomas (five additional aberrations per case, compared with two). Chromosomes 1 and 12 were the chromosomes most frequently (one fourth of the cases) involved in additional structural changes, but with several different breakpoints. No differences were identified between the karyotypic profiles of monophasic and biphasic synovial sarcomas. PMID:1665704

  19. Ten cases of metastatic cervical cancer with the treatment of permanent 125I seeds interstitial implants

    International Nuclear Information System (INIS)

    Objective: To investigate the clinical effect of permanent 125I seeds interstitial implants for metastatic cervical cancer. Methods: Under the guidance of the B-sonography, 125I seeds were implanted into the eleven cervical lymph nodes of ten patients who had been given tumor resection. The pain relief and tumor size were observed in regular follow-up after one-month treatment. Results: All the patients were followed up for 6-14 months,and the postoperative recovery was good with no complication. One month after the implantation, the pain symptom was alleviated entirely in two nodes and partly in nine nodes. The tumor size shrank in ten nodes while there was no change in one node after one month. Conclusion: Permanent 125I seeds interstitial implants for metastatic cervical cancer is a safe, minimally invasive and effective treatment. (authors)

    Full Text Available Objective: To analyze data of cases with lung cancer (LC diagnosed in our clinic over one year period and compare them with data of cases with LC diagnosed before ten years. Method: The demographic data, radiological and bronchoscopic findings, diagnostic methods, and histological type and stages of the patients diagnosed with lung cancer in year 2005 were evaluated. Results: Over one year period, 138 patients were diagnosed with LC. 104 (75.4% were men and 34 (24.6% were women. Mean age was 63.78±9.53 (38-83. 118 (86.5% of the patients had 39±16.34 (5-90 pack-years smoking history. Squamous cell carcinoma (SCC was diagnosed in 40.6% of patients, adenocarcinoma in 29.0%, small cell carcinoma in 21.0%, conbined type in 8.0% and carcinoma with unidentified cell type in 1.4%. Squamous cell carcinoma was more common among smoking patients. It was determined that the distribution of histological types in this study was similar to the previous studies, however the incidence of LC was found as increased in females in our study when compared to previous studies. Conclusion: We conclude that SCC is the most common histological type in patients with LC in our clinic and the male to female ratio for LC is decreasing.

    Full Text Available Background: Primary dysmenorrhea is a common disabilitating factor in most of the adolescent girls. It is a major cause of inability to concentrate on their work or studies, class or school absenteeism, inability to perform in their academic activities. This study conducted to assess the effect of non-invasive treatments for pain relief during dysmenorrhea. Aim and Objectives: To study the effect of Conventional TENS and Spinal mobilization on pain in Primary Dysmenorrhea in adolescent girls. Materials and Methods: Fifty adolescent girls aged between 14-18 years were selected for the study that fulfilled the inclusion criteria. Quasi experimental study was done to compare the effect of TENS and Maitland’s spinal mobilisation in Adolscent girls suffering from primary dysmenorrhea. They were randomly divided in two groups: Group A for TENS (n= 24 and Group B for spinal mobilisation (n= 26 and participant’s menstrual history was recorded. Girls with severe dysmenorrhea, pelvic pathology and spinal pathology were excluded from this study. Treatment was given on 1st and 2nd day of menstruation period. Adolescent girls marked the Short form Mc gill Pain Questionnaire (SFMPQ which includes PPI and VAS before and just after the treatment. Total scores were noted and subjected to statistical analysis. Result: Data was analyzed using Mann Whitney U test which compared data between groups; results were not statistically significant (p> 0.05 for SFMPQ, PPI and VAS. Pain relief was approximately the same for the two groups. Conclusion: The study concludes that TENS and mobilisation both are effective reducing pain among adolescent girls who suffer from primary dysmenorrhea.

    Full Text Available 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.

The writhing test (Siegmund Chemical Test was used for the pharmacological screening. The cytotoxicity of all the extracts was tested on KB (Human epidermoid carcinoma and Vero (African green monkey kidney cell lines with taxotere as positive control. A TLC chemical screening of the extracts was carried out to detect the major chemical classes present in the plants. The data of the traditional medicine were confirmed, since eight plants out of ten were active, aqueous and ethanolic extracts being the most active. Moreover, only C. podolaena leaf extracts were cytotoxic (87% of inhibition on KB. This work opens the way for the research of the active molecules from these plants and for their use as leads in the synthesis and the pharmacomodulation of compounds with analgesic potentiality.

    Ten patients (6F, 4M) with recurrent Tolosa-Hunt syndrome are reported. Besides ocular motor symptoms, one patient had trigeminal nerve involvement, one had ipsilateral ocular sympathicoplegia with miosis and ptosis, and one tinnitus during an episode of Tolosa-Hunt syndrome, ipsilateral to the pain side. One patient had Bell's palsy, one had a possible Raeder's syndrome, and one had a period of tinnitus between the Tolosa-Hunt syndrome episodes. Three of the 10 patients reported periods of periocular pain without ophthalmoplegia between the Tolosa-Hunt episodes, the pain located ipsilateral to the ophthalmoplegic side in the Tolosa-Hunt episodes. Systemic symptoms associated with Tolosa-Hunt syndrome, e.g., back pain, chronic fatigue, arthralgia, gut problems among others, occurred with the same frequency in these 10 patients as in an earlier report. Seventy per cent of the patients had signs of inflammation in serum during a period of Tolosa-Hunt syndrome. Orbital phlebograms showed pathologic signs in four of the five patients investigated during a Tolosa-Hunt period. One phlebogram was normal in a sixth patient when performed during a period of unilateral periocular pain without ophthalmolegia. Magnetic resonance imaging of the head (with contrast) was only performed in three patients during the Tolosa-Hunt period: one showed signs of inflammation in the middle fossa and two were normal. In one of the patients with normal magnetic resonance imaging, the orbital phlebogram was pathologic. Steroid treatment promptly relieved the pain in all patients. PMID:10668117

    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.

The medicinal plant can prove as effective antimicrobial agent to check the secondary infections in treated cancer patients.

  11. 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.

Methods The clinical data were reviewed, including presentation, imaging and prognosis of 10 patients suffered from intracranial clear cell meningioma for 2 months-7 years and underwent surgical treatment. The patients included five males and five females with the age from nine to sixty-two years old (mean 35.43. 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?

    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.

    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.

    Full Text Available Objective: Carbon monoxide (CO poisoning is a common problem in various countries, especially in Winter months. CO exposure results in the formation of carboxyhemoglobin (COHb, which is responsible for toxicity symptoms. In this study, we aim to demonstrate the demographic features and seasonal variations of this particular public health problem. Materials and Methods: We retrospectively evaluated hospital police reports and medical records of 2417 ED patients diagnosed with CO poisoning between 1999 and 2009. Sources of exposure, seasonal variation and demographic characteristics were analyzed. Results: The mean age of the patients, of whom 1418 (58.7% were female, was 29±18 years. While 1708 patients (70.7% were admitted to adult ED, 709 (29.3% patients were admitted to pediatric ED. January and subsequent Winter months represented the most dangerous periods for CO exposure. No intentional (suicidal attempt exposure to CO intoxication was reported and the major cause for intoxication included unsecured stoves and gas heaters. Conclusion: Emergency physicians should be familiar with symptoms and remedies of CO intoxication, which still constitutes a serious health problem.

    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.

    Full Text Available [...] Abstract in english Background: Carotid body tumors arise from a cellular conglomerate located at the carotid bifurcation. Progressive enlargement can involve the arterial wall and neighbor cranial nerves. Aim: To report a series of 10 patients treated of carotid body tumors and review national experience. Patients and [...] methods: Between 1984 and 2006, we operated 8 women and 2 men, aged 19 to 75 years, with this type of tumor. Results: The most common cause for consultation was a cervical mass in 90%, with a mean evolution lapse of 13.2 months (range 3 to 126). In all cases, diagnosis was confirmed with angiographic imaging and histopathology. Ten tumors were surgically removed with no complications. Eighty percent of tumors were in stage II according to Shamblin classification. During long term follow up all patients have remained asymptomatic. Only 31 carotid body tumors have been reported in Chilean medical literature during a 43 year period. Conclusions: Paragangliomas of the carotid body can be diagnosed in clinical grounds, requiring vascular imaging. These infrequent lesions are generally benign, early surgical removal by surgeons with vascular expertise avoids neurological and or vascular complications

    Purpose: To assess the diagnostic value of two-dimensional coronary magnetic resonance (MR) angiography in patients evaluated for ischemic heart disease. Materials and methods: Ten patients who underwent selective cardiac catheterization with coronary MR angiography were evaluated with two-dimensional coronary MR angiography. Coronary MR angiography was performed with breath-hold fat-suppressed ECG-gated Turbo-FLASH with K-space segmentation using a 1.5 T imager. Results: The left main coronary artery, proximal left anterior descending artery, circumflex artery and right coronary artery were demonstrated in all cases. Continuous segments (mean) of left anterior descending, circumflex and right coronary arteries visualized on MRA were 6.72 +- 3.16 cm, 3.67 +- 4.81 cm and 7.93 +- 3.12 cm respectively. The overall sensitivity for detection of hemodynamically significant coronary artery lesion (?50%) was 62.5% respectively. Conclusion: Breath-hold two-dimensional coronary MR angiography was useful in showing relatively long segments of the main coronary arteries and also has potential in depicting hemodynamically significant coronary artery lesions

    Directory of Open Access Journals (Sweden)

    Ra?a Biljana

    2010-07-01

    Full Text Available In this study we present the results of a ten year survey of the aquatic macroinvertebrate fauna along four karst rivers: Jadro, Žrnovnica, Grab and Ruda, all of them situated in the Middle Dalmatia region of Croatia, in an attempt to construct the Iliric Biotic Index, which will be more applicable for the water quality analysis than the most frequently applied biotic index in Croatia, the Italian Modification of Extended Biotic Index. The rivers geologically belong to the Dinaric karst, unique geological phenomena in Europe. Benthic macroinvertebrates were collected along each river at 15 sites by standard methods of sampling along with several physicochemical parameters, including: temperature, dissolved oxygen, carbon dioxide, alkalinity, hardness and pH. Univariate and multivariate techniques revealed differences in the macroinvertebrate community structure as well as in physicochemical parameters between the Karst rivers and continental rivers. Based on those differences, the Iliric Biotic Index was proposed as the standard of karst river water quality in Croatia in accordance with the EU Water Framework Directive. Differences between the Iliric Biotic Index and the most commonly used biotic indices in the European Community and the USA (The Biological Monitoring Working Party (B.M.W.P. scores, i.e. Extended Biotic Index, Indice Biotique, Family Biotic Index suggest that karst rivers need a new biotic index.

    2015-01-01

    We present the results of the multi-frequency scatter time measurements for ten radio pulsars that were relatively less studied in this regard. The observations were performed using the Giant Meterwave Radio Telescope at the observing frequencies of 150, 235, 325, 610 and 1060~MHz. The data we collected, in conjunction with the results from other frequencies published earlier, allowed us to estimate the scatter time frequency scaling indices for eight of these sources. For PSR J1852$-$0635 it occurred that its profile undergoes a strong evolution with frequency, which makes the scatter time measurements difficult to perform, and for PSR J1835$-$1020 we were able to obtain reliable pulse broadening estimates at only two frequencies. We used the eight frequency scaling indices to estimate both: the electron density fluctuation strengths along the respective lines-of-sight, and the standardized amount of scattering at the frequency of 1 GHz. Combining the new data with the results published earlier by Lewandowsk...

    Full Text Available In the past ten years, 45 cases of infantile spasm treated in our center. From these patients, 15 cases received only steroid, other 15 cases only clonazepam, and the rest, a combination of clonazepam and steroid. All patients were observed for two years. This is a retrospective study, the data being extracted from patients record. A number of patients were treated in ambulatory and the others were patients of the hospital. The result of comparison of optimal control of seizures are as follow: 1 In only steroid group 27 percent of the patients were free of seizure, 2 In only clonazepam group 28 percent showed no seizure, 3 in combined clonazepam and steroid group 39% were seizure-free. Based on this trial we believe that treatment of infantile spasm with combined steroid and clonazepam is better than any of them alone. Considering these results, we believe that the treatment of infantile spasm with a combination of steroid and clonazepam is preferable to these drugs.

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.

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.

  4. 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

    Necrobiosis lipoidica is a rare granulomatous disorder of the skin. In up to 30% of the affected patients it can lead to ulcerations, which can impair the quality of life and are also very difficult to treat. Its pathogenesis is not fully understood. Only few studies focussing on necrobiosis lipoidica can be found, but none of them focus on ulcerated necrobiosis lipoidica. Therefore, we collected demographic data and comorbidities and assessed treatment options for patients with ulcerated necrobiosis lipoidica. Data of patients who were treated in the wound care centre of the University Hospital of Essen for ulcerated necrobiosis lipoidica over the past 10 years were retrospectively analysed. Hence, data of altogether ten patients (nine women and one man) with ulcerated necrobiosis lipoidica were collected. Of these, 70% of the patients had diabetes mellitus of which 30% had type I diabetes and 40% had type II diabetes; 60% of the patients suffered from arterial hypertension, obesity and hypercholesterolaemia; 40% of the patients suffered from psychiatric disorders such as depression and borderline disorder. Our clinical data demonstrate an association of ulcerated necrobiosis lipoidica and aspects of metabolic syndrome. This leads to a conclusion that ulcerating necrobiosis lipoidica can be seen as part of a generalised inflammatory reaction similar to the inflammatory reaction already known in the pathophysiology of rheumatoid diseases or psoriasis. In patients with clinical atypical painful ulcerations, necrobiosis lipoidica should be considered as a possible differential diagnosis. Therapists should be aware of associated aspects in patients with ulcerated necrobiosis lipoidica who besides diabetes often suffer from other aspects of a metabolic syndrome with increased cardiovascular risk factors. Therefore, these related comorbidities should also be diagnosed and treated. PMID:24119190

  6. 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 the importance of correlation with other modalities in providing cost effective patient management.

    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.

  8. Early detection, early symptom progression and symptomatic remission after ten years in a first episode of psychosis study

    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”.

In this study carpal tunnel and cubital tunnel syndrome were the most frequent (81.7% and 15.8% respectively. In 23.5% of patients with carpal tunnel syndrome, electrophysiological findings were negative but there was no false positive result. Concurrent carpal tunnel syndrome with other syndromes were found in three cases of cubital tunnel syndrome, two cases of thoracic outlet syndrome and one case of Guyon's canal syndrome."n"nConclusion: Constellation of symptoms, physical examination and electrophysiologic-al findings altogether should be considered for correct diagnosis of nerve entrapment syndromes in the upper extremity. Simultaneous entrapment in the other regions of the same nerve or other nerves in the same extremity is a probable condition

    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.

  16. 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)

    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...

  18. Computational study of the structural and vibrational properties of ten and twelve vertex closo-carboranes

    International Nuclear Information System (INIS)

    Calculations using ab initio Hartree-Fock and Density Functional theories, the latter employing the B3LYP functional, in combination with a number of large standard basis sets ranging from 6-31G** to cc-pVDZ, have been performed on a series of ten and twelve vertex closo-carborane isomer species. Results obtained for optimized structural parameters and molecular properties are presented for 1,2-, 1,6- and 1,10-C2B8H10 and 1,2-, 1,7- and 1,12-C2B10H12 and compared, where possible, with both earlier theoretical data and experiment. Irrespective of the model chemistry chosen, the para-isomer in each class of carborane cluster is found to be the most stable species, corresponding to a structure in which the cage carbon atoms are positioned at diametrically opposed ends of the respective polyhedron. Boron-hydrogen and carbon-hydrogen bond lengths are found to change little on going from isomers of one particular cage size to another, supporting analogous conclusions previously established for small closo-carborane cages possessing five, six and seven vertices. The calculated vibrational spectra of the isomers of both decacarborane and dodecacarborane are seen to be similar to each other and reflect a high degree of rigidity within each cluster. Key polyhedral skeletal breathing modes along with characteristic boron-hydrogen and carbon-hydrogen stretching frequencies are identified in the spectra and compared with experiment. Thermochemical data relating to each species are also analyzed

    2012-07-01

    A 58-year-old female with a history of dermatomyositis was receiving large oral doses of steroids. She had pulmonary tuberculosis and developed a fever, systemic exudative erythema, exanthema, and epidermolysis covering 30% of her body surface area while being treated with four agents, including isoniazid (INH) and rifampicin (RFP). Histopathologically, eosinophilic necrosis was observed in all layers of the epidermis and a diagnosis of Stevens-Johnson syndrome (SJS) progressive toxic epidermal necrolysis (TEN) was made. The drugs suspected in the drug-induced lymphocyte stimulation test (DLST) re-testing were INH and RFP, and the DLST was considered to be important during the recovery period as well as in the acute phase. Early treatment with plasma exchange therapy and large quantities of intravenous immunoglobulin (IVIG) was successful. Plasma exchange therapy and IVIG are extremely effective when SJS and TEN occur in a patient already on high-dose steroid therapy. Note that the incidence of SJS and TEN is believed to be higher in patients with collagen disease, such as in our case, as compared to the general population. PMID:22991850

    Full Text Available Purpose: Ten years retrospective study to evaluate the bacteriological spectrum of community acquired acute bacterial meningitis (CAABM. Methods: Cerebrospinal fluid (CSF samples from 385 clinically suspected cases of pyogenic meningitis were processed for cell counts, cytospin Gram stain, culture, antigen detection by latex agglutination (LAT and antibiotic susceptibility test. Eighteen of these CSF samples were also subjected to a polymerase chain reaction (PCR assay for detection of pneumococcal DNA. Results: The etiological agent could be identified in 284 (73.8% of the total 385 cases by culture and/or smear and /or LAT. Streptococcus pneumoniae was the predominant pathogen accounting for 238 (61.8% cases. Haemophilus influenzae and Neisseria meningitidis accounted for 7 (1.8% and 4 (1% cases respectively. Other gram negative bacilli, Streptococcus spp. and Staphylococcus aureus were isolated from 19 (4.9%, 9 (2.3% and 7 (1.8% cases respectively. Conclusions: Streptococcus pneumoniae remains the major aetiological agent of CAABM both in adults and children in our set-up. No penicillin resistance was detected among the isolates. Further research should focus on preventable aspects of CAABM, especially pneumococcal vaccines, to help reduce the disease burden.

    The potential benefit of nonpharmacological adjunctive therapy is not well-studied following major abdominal surgery. The aim of the present study was to investigate transcutaneous electrical nerve stimulation (TENS) as a complementary nonpharmacological analgesia intervention during weaning from epidural analgesia (EDA) after open lower abdominal surgery. Patients were randomized to TENS and sham TENS during weaning from EDA. The effects on pain at rest, following short walk, and after deep breath were assessed by visual analog scale (VAS) grading. Number of patients assessed was lower than calculated because of change in clinical routine. Pain scores overall were low. A trend of lower pain scores was observed in the active TENS group of patients; a statistical significance between the groups was found for the pain lying prone in bed (p open colon surgery. Further studies are warranted in order to verify the potential beneficial effects from TENS during weaning from EDA after open, lower abdominal surgery. PMID:26541070

  3. 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.

    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.

    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 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.

    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.

    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.

    NonaSantfeliu study: A review is presented of the studies that are part of the initial overall assessment and the studies performed during the 10 years of follow-up of a cohort of nonagenarians. It is a population-based study of 186 subjects, 76.5% women, mean age at baseline of 93.06 years, a quarter (26%) being institutionalized. The mean of baseline Barthel index was 60.8, and the mean for the Lobo's cognitive minimental was 21. Nonagenarian males with low comorbidity had more successful aging criteria than women with high comorbidity quantified with the Charlson Index. The survival rate at 10 years follow-up was very low, and 95.6% of the population had died. This represented an annual mortality rate of 9.5%. A common denominator on assessing all different annual cuts, is that the most important factors associated with mortality are those related to geriatric assessment, such as a function, cognition, dementia, and cumulative comorbidity and multiple medications, compared to more traditional risk factors described in younger populations.

    1997-01-01

    The potential employment effects of the North American Free Trade Agreement (NAFTA) was the central concern of debate before the treaty was eventually passed. Panel data on unemployment rates in 10 major industries in the US during 1983-1994 were analyzed to assess the sensitivity of unemployment rates with respect to industry characteristics, macroeconomic variables, and Canadian and Mexican immigration to the US in the aftermath of the advent of NAFTA. The industries studied are mining; construction, durable goods, nondurable goods, transportation and public utilities; wholesale and retail trade; finance, insurance, and real estate; services; agriculture; and government. Analysis of the data determined that the output produced by the industry, unemployment insurance coverage, and interest rates are significant determinants of industry unemployment rates, but union presence does not affect industry unemployment. Both Canadian and Mexican immigrants seem to complement the US labor force, with Canadian immigrants being highly complementary to US labor. The Chow test found no evidence that NAFTA has changed the structure of unemployment determination in the industries studied. PMID:12321541

    Full Text Available Cancer is nowadays one of the most important health problems. In Romania cancer is the second in generalmorbidity after cardio-vascular diseases, being followed by respiratory diseases, accidents and trauma. Considering thefact that cancer has an insidious start, a slow irreversible development towards physical and psychic invalidity, and that it affects both the person and the family and society, we can say it is very important to have a study of this illness from thesocial and medical point of view. The cytological examination offers, apart from the highlighting of the tumour cells, thepossibility of assessing the hormonal status, and also of identifying vaginal flora. Cervical cancer is a serious chroniccondition, which has great medical and social importance and has a severe evolution when detected in advanced stages.

    Simonsen, Erik; Evensen, Julie

    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.

    Background. Obesity is a growing public health problem associated with increased morbidity and rate of death. Postmortem examination is imperative to determine the cause of death, to detect clinically unsuspected disease entities, and consequently to determine the actual impact of obesity on patient mortality. Methods. A total of 849 adult autopsies were retrospectively reviewed. Obese (BMI ? 30?kg/m2) and nonobese patients were separately studied. The primary cause of death in each group was categorized into malignancy, infection, stroke, ischemic and nonischemic heart disease, pulmonary embolism, hemorrhage, and primary nonneoplastic diseases of different organ systems. Results. Of 849 autopsies, 32.3% were obese. The leading causes of death in the obese population were malignancy (31.4%), infection (25.9%), ischemic heart disease (12.8%), and pulmonary embolism (6.2%). Obese individuals were statistically more likely to die from pulmonary embolism and liver disease and less likely to die from neurologic diseases and nonischemic heart disease. Conclusion. Autopsies on obese individuals constitute a third of all adult medical autopsies in our center. Increased death rates in the obese due to pulmonary embolism and liver disease should receive special clinical attention. Autopsy findings in the obese population should contribute to overall premortem disease detection, prevention, and management. PMID:25653872

The purpose of the register is to gain information about severe allergic reactions to food in Norway and to survey food products in relation to allergen labelling and contamination. Cases are reported on a voluntary basis by first line doctors, and submitted together with a serum sample for specific IgE analysis. The register has received a total of 877 reports from 1 July, 2000 to 31 December, 2010. Two age groups, small children and young adults are over-represented, and the overall gender distribution is 40:60 males-females. The legumes lupine and fenugreek have been identified as two “new” allergens in processed foods and cases of contamination and faults in production of processed foods have been revealed. The highest frequency of food specific IgE is to hazelnuts and peanuts, with a marked increase in reactions to hazelnuts during the last three years. The Food Allergy Register has improved our knowledge about causes and severity of food allergic reactions in Norway. The results show the usefulness of population based national food allergy registers in providing information for health authorities and to secure safe food for individuals with food allergies.

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

  11. Ten-Year Retrospective Longitudinal-Study of Student Perspectives on Value of REU

    Science.gov (United States)

    Slater, T. F.; Slater, S. J.

    2013-12-01

    For more than two decades, federal agencies have been enthusiastically supporting summer research experiences for undergraduates. These REU programs are tacitly intended to increase retention and provide "an important educational experience" for undergraduates, particularly women, minorities and underrepresented groups. Numerous authors (viz., Laursen, Lopatto, Dolan, among many others) have enthusiastically described positive impacts of summer REU programs from exit interview data. These results include enhanced persistence to pursue STEM careers and confirmed desire to attend graduate school in the field targeted by a particular REU. Perhaps surprisingly, negative student experiences are rarely described in the scholarly literature, but do appear in more informal publications (viz., Gueterma, 2007). One wonders how REU alumni, looking back over their entire collective portfolio of experiences, now perceive the educational value of their REU experience relative to their other educational experiences. To obtain a backwards-looking, reflective description from REU alumni on the value of their REU experiences, we conducted a 10-year, two-stage study was designed to explore the ways in which the REU acted as an educational experience for 51 women from a single geoscience sub-discipline. The first phase was an ex post facto longitudinal analysis of data, including multiple interviews with each participant during their REU, annual open-ended alumni surveys, faculty interviews, and extensive field notes, over a 10-year period. This analysis informed the second phase, a clinical interview. Over 10 hours of interviews with 8 participants were conducted and analyzed. These 8 participants were selected to represent a variety of career stages, and for their potential to reflect on a wide variety of educational experiences. Results from the interviews, done many years after their REU experience, indicate that the interviewees' REU did not provide a substantive educational experience related to the nature of scientific work, the scientific process, or the culture of academia when considered in a comparative context of students' other educational experiences. Results further indicated that the REU did not serve to transform participants' conceptions about themselves as situated in science, and learning gains with regard to other aspects of the self, were somewhat limited. Instead, the data suggests that these women arrived at the REU with pre-existing and remarkably strong conceptions in these areas, and that the REU did not functional to alter those states. These conceptions were frequently the result of interactions with mentors/scientists from middle school until well into the undergraduate period.

    2002-01-01

    This book employs a familiar vehicle in library literature—the case study—but in a departure from the expected, takes that time-honored genre into a new dimension. Shuman uses the conversational narrative as a vehicle for portraying 40 security and safety issues that may arise in libraries, disturbing or vexing patrons and library staff members, alike. Unlike the traditional narrative approach of other case study books, in this work, each case is presented as a soliloquy, within a fictional but plausible library situation, whereby the protagonist uses his or her own colorful mode of expression

    Cannabis is the most commonly used illicit drug in Europe, and is generally regarded as having low acute toxicity. We present the findings of the first 6 months of data collection from the Euro-DEN project on presentations related to cannabis use to further understand the acute toxicity related to the use of cannabis. Data was extracted on clinical features, treatment and outcome from the Euro-DEN minimum dataset for all cases of acute recreational drug toxicity reported 1st October 2013 to 31st March 2014 for all cannabis-related presentations. Of 2198 presentations reported by 14 of the 16 Euro-DEN centres, 356 (16.2 %) involved cannabis either alone or together with other drugs/alcohol. There were 36 that involved lone use of cannabis (1.6 % of all presentations). Of the 35 non-fatal lone cannabis presentations, the most commonly reported features were neuro-behavioural (agitation/aggression 8 (22.9 %), psychosis 7 (20.0 %), anxiety 7 (20.0 %)) and vomiting 6 (17.1 %). Most patients (25, 71.4 %) received no treatment and 30 (85.7 %) were discharged/self-discharged from the ED. There was one fatality amongst these lone-cannabis cases: an 18-year-old male collapsed with an asystolic cardiac arrest whilst smoking cannabis and suffered hypoxic brain injury related to prolonged cardiac arrest. THC was detected in a urine sample taken at ED arrival; no other drugs were detected. Lone acute cannabis toxicity was typically associated with neuro-behavioural symptoms and vomiting. Although uncommon, severe toxicity including cardiovascular toxicity and death may be under-recognised, and it is important that Emergency Physicians are aware of this. PMID:25652342

    Jordan, S

    1997-10-01

    This paper describes why case studies deserve a place in the centre of the bioscience curriculum, and how they have been used as a vehicle to improve care and save lives. A knowledge of drugs, their side-effects and interactions is becoming increasingly important to nurses. One powerful way to convey this information is the case study, which, despite its limitations, has the potential to endow difficult topics in therapeutics with the power of the narrative. The author suggests that case study projects encourage students to forge theory-practice links, related to their own specialist areas. When shared with their colleagues, these encourage the class by illustrating 'bioscience in action' and endowing the subject with the 'reality factor'. They also provide rich qualitative data for evaluating and delineating the curriculum. These case studies demonstrate the value of evidence-based practice; although case data is part of the evidence, it can never substitute for evidence-based practice. This paper builds on the findings of the author's PhD in postregistration nurse education; the examples described here are typical of 151 such cases in the research project. PMID:9370631

    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.

    The dual-specificity tyrosine-phosphorylation-regulated kinase 1A (DYRK1A) gene, located on chromosome 21q22.13 within the Down syndrome critical region, has been implicated in syndromic intellectual disability associated with Down syndrome and autism. DYRK1A has a critical role in brain growth and development primarily by regulating cell proliferation, neurogenesis, neuronal plasticity and survival. Several patients have been reported with chromosome 21 aberrations such as partial monosomy, involving multiple genes including DYRK1A. In addition, seven other individuals have been described with chromosomal rearrangements, intragenic deletions or truncating mutations that disrupt specifically DYRK1A. Most of these patients have microcephaly and all have significant intellectual disability. In the present study, we report 10 unrelated individuals with DYRK1A-associated intellectual disability (ID) who display a recurrent pattern of clinical manifestations including primary or acquired microcephaly, ID ranging from mild to severe, speech delay or absence, seizures, autism, motor delay, deep-set eyes, poor feeding and poor weight gain. We identified unique truncating and non-synonymous mutations (three nonsense, four frameshift and two missense) in DYRK1A in nine patients and a large chromosomal deletion that encompassed DYRK1A in one patient. On the basis of increasing identification of mutations in DYRK1A, we suggest that this gene be considered potentially causative in patients presenting with ID, primary or acquired microcephaly, feeding problems and absent or delayed speech with or without seizures.

  2. 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 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

    Background The PR interval (PR) as measured by the resting, standard 12-lead electrocardiogram (ECG) reflects the duration of atrial/atrioventricular nodal depolarization. Substantial evidence exists for a genetic contribution to PR, including genome-wide association studies that have identified common genetic variants at nine loci influencing PR in populations of European and Asian descent. However, few studies have examined loci associated with PR in African Americans. Methods and Results We present results from the largest genome-wide association study to date of PR in 13,415 adults of African descent from ten cohorts. We tested for association between PR (ms) and approximately 2.8 million genotyped and imputed single nucleotide polymorphisms. Imputation was performed using HapMap 2 YRI and CEU panels. Study-specific results, adjusted for global ancestry and clinical correlates of PR, were meta-analyzed using the inverse variance method. Variation in genome-wide test statistic distributions was noted within studies (lambda range: 0.9–1.1), although not after genomic control correction was applied to the overall meta-analysis (lambda: 1.008). In addition to generalizing previously reported associations with MEIS1, SCN5A, ARHGAP24, CAV1, and TBX5 to African American populations at the genome-wide significance level (P<5.0×10?8), we also identified a novel locus: ITGA9, located in a region previously implicated in SCN5A expression. The 3p21 region harboring SCN5A also contained two additional independent secondary signals influencing PR (P<5.0×10?8). Conclusions This study demonstrates the ability to map novel loci in African Americans as well as the generalizability of loci associated with PR across populations of African, European and Asian descent.

  4. 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

    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.

  12. Poroelastic behaviour of the degenerating human intervertebral disc: a ten-day study in a loaded disc culture system

    Directory of Open Access Journals (Sweden)

    KS Emanuel

    2015-06-01

    Full Text Available The intervertebral disc (IVD allows flexibility to the vertebral column, and transfers the predominant axial loads during daily activities. Its axial biomechanical behaviour is poroelastic, due to the water-binding and releasing capacity of the nucleus pulposus. Degeneration of the intervertebral disc presumably affects both the instantaneous elastic response to the load on the IVD and the subsequent interstitial flow of fluid. This study aims to quantify the poroelastic behaviour of the IVD and its change with degeneration, as defined by the magnetic resonance imaging-based Pfirrmann Score (PS. For a period of ten days, 36 human lumbar IVDs were loaded with a simulated physiological axial loading regime, while deformation was monitored. The IVDs responded to the loads with instantaneous elastic and slow poroelastic axial deformation. Several mechanical parameters changed throughout the first five days of the experiment, until the IVDs settled into a dynamic equilibrium. In this equilibrium, degeneration was significantly related to a decrease in disc height loss during the daytime high load phase (? = -0.49, and to a decrease in the rate of this deformation during the final half hour of each day (? = -0.53. These properties were related to the nucleus glycosaminoglycan/hydroxyproline (GAG/HYP ratio, rather than GAG content alone, indicating that remodelling of the extracellular matrix reduces poroelastic properties of the IVD. This implies that the degenerated discs have a reduced capacity to bind water and/or a reduced resistance against fluid flow. The resulting loss in hydrostatic pressure may further change cell behaviour in the nucleus pulposus.

  13. A case study of Impetigo

    1993-05-01

    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

  16. Incidence of cancer in children residing in ten jurisdictions of the Mexican Republic: importance of the Cancer registry (a population-based study)

    International Nuclear Information System (INIS)

    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). 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). 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. 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

  2. Experimental study of a fast plasma focus discharge operated in the range of tens of joules emitting neutrons

    International Nuclear Information System (INIS)

    In this doctoral research, a small plasma focus discharge operated at tens of joules and kilo amperes has been experimentally studied. This device produces a coaxial discharge by an electrode arrange which consists of an inner electrode, a cylindrical insulator, and an outer electrode. The discharge is driven by a capacitive generator and it is operated at pressures of some millibars. Typical electrical parameters of the device are T/4?150ns, 160 nF, 40 nH, 30-100J, 40-70kA. When Deuterium is used as filling gas, neutrons are produced by fusion reactions. The device, namely PF-50J, is one of the most extreme plasma focus reported in the literature to emit neutrons. The results of this work have demonstrated that the same dynamics found in larger machines (operated from kJ to MJ) is also found in this extremely low energy device which means that after the discharge is initiated, a plasma sheet is formed over the insulator. By the action of the Lorentz force, the plasma sheet moves axially. When the sheet reaches the top end of the inner electrode, it starts to implode radially to finally form a dense plasma column (pinch). Finally, the plasma column is disrupted 5-10ns after column formation. Shock piston velocities of the order of 104-105m/s were estimated from experiments for each discharge dynamical phase. Typical pinch densities of 1024-25m-3 were also observed in PF-50J. An interesting feature observed in this work is the formation of axial jet-like structures which appears at late times almost hundred nanoseconds after pinch disruption. These structures are composed by a metallic plasma which results from ablation of the inner electrode. The mechanism responsible for the formation of this kind of structure is still unknown, although evidence suggests that the phenomena is not related to the pinch formation process. One of the principal motivations of this thesis was to study the optimization for neutron emission in the PF-50J device. This plasma focus is expected to yield 103-104 neutrons per pulse when is operated with deuterium. Standard detection techniques, for example neutron activation detectors, present detection limits higher than 105 neutrons per pulse, so it was necessary to develop a measurement method for higher efficiency detectors based on the use moderated proportional counter tubes for the purpose of neutron optimization. In contrast to low rate continuous regime, this detectors show pulse piling up when irradiated with pulsed neutrons, which make impossible to count events with standard nuclear electronics. In this thesis, it is presented a detailed study of pulsed piling up statistics in the proportional counter and a complete characterization of the 3He tubes based detection system. Regarding that the net area of detector output signal is proportional to the number of detected events, a counting model was developed and thus a methodology for measurement of the neutron yield is proposed. Special emphasis was put on the sources of fluctuation that affects the measurement process, which are given by the counting statistics, piling up statistics, and background electrical noise. As a result, the methodology allows measurements uncertainties for pulsed D-D fusion neutrons lower than 30% in the range of Y ? 3x103n/shot, reducing in this way by almost two order of magnitude the detection limit of the state of art techniques. A theoretical study of the detection frequency or reproducibility for pulsed neutron sources is also presented. Comparisons with results in PF-50J show that theoretical models for reproducibility are reasonable high boundary estimations for the experimental values. The optimization study is presented in the last part of this work. Optimal conditions for neutron emission were experimentally obtained. An interesting finding is the observation of two regimes for pinch formation and neutron emission. The first regime is related to the pinch formation close to the first current maximum in the first quarter of period, while in the second one these phenomena are observed at higher press

    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.

  5. 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

    This paper discusses the Saudi Arabian case by Abdallah Adlan and Henk ten Have, published in a 2012 issue of the Journal of Bioethical Inquiry, regarding a congenitally disabled child enrolled in a research project examining the genetics of her condition. During the course of the study, her father was found not to be genetically related, and the case discussed the dilemma between disclosing to the family all findings as promised in consent documents or withholding paternity information because of the likely severe social repercussions. Using Adlan and ten Have's example, this paper proposes a framework to consider cases outside of the conventional bioethics frame of reference, splitting the bioethical task into three elements: understanding the problem from the patient's and the clinician's perspective and then engaging in dialogue to decide what to do next. The process of dialogue between affected parties is vital. Presuming that there is a common morality undermines the effectiveness of the dialogue needed to find a resolution. PMID:26016616

    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.

    Most energy-management case studies focus on capital investments in new technical equipment, such as more-efficient boilers, lighting systems or computerised energy-management systems. The wide range of technical options for saving energy are well documented and advertised. Another aspect of energy management - namely the achievement of 'no cost' or 'good housekeeping' measures through well-organised motivation and incentive campaigns - is not so well reported. This is due to there being few examples of this type of project, which itself probably reflects the energy managers' preferences for dealing with 'hard' engineering rather than 'soft' people-orientated issues. This paper documents the development and implementation of a motivation campaign for the Social Services Department of Coventy City Council which was novel for two reasons: first, it is believed to be the first motivation campaign in a Social Services department; and secondly, it involved the use of training, incentives and feedback in an integrated way that it is believed greatly boosted its effectiveness.

    Full Text Available Malaria in pregnancy has remained a major public health problem in Nigeria. The treatment of malaria in pregnancy at the Lady of Apostles Catholic Hospital, Oluyoro, Oke-Ofa, Ibadan in South West Nigeria between 1999 and 2008 was studied retrospectively. The objective of the study was to assess the rational use of anti-malarial drugs in the treatment of malaria in pregnancy. A total of 580 case notes of patients were collected from the medical records department. The most prevalent age group of between 15 and 20 years accounted for two hundred and two (202 (34.8%, while the least prevalent age group of between 41 and 45 years was 10 (1.7%. Majority of the patients 299 (39.5% had secondary education, and those with tertiary education being 200 (34.5%. The gestational fetal age at which malaria infection was most prevalent was between 4 and 6 months, while the least prevalent gestational fetal age was between 7 and 9 months. There was a rapid but consistent decline in the use of Chloroquine forty eight (48 (23% from 1999, to 3 (5% in 2008. Sulfadoxine-Pyrimethamine 6 (3.8% was observed to have a steady rise in use during the years 1999 to 30 (18.8% in 2008. In 1999 and 2000 there was no ACT used. In 2001, 2 (0.9% ACTs were used and increased significantly (p>0.01 to fifty three (53 (24.8% in 2008. The community was averagely literacy and most of the women could therefore be trained on proper antenatal care through seminars and counseling thereby reducing the incidence of malaria in pregnancy.

    2015-01-01

    Recent studies investigating ultraendurance athletes showed an association between excessive fluid intake and swelling of the lower limbs such as the feet. To date, this association has been investigated in single-stage ultraendurance races, but not in multistage ultraendurance races. In this case study, we investigated a potential association between fluid intake and feet swelling in a multistage ultraendurance race such as a Deca Iron ultratriathlon with ten Ironman triathlons within 10 consecutive days. A 49-year-old well-experienced ultratriathlete competed in autumn 2013 in the Deca Iron ultratriathlon held in Lonata del Garda, Italy, and finished the race as winner within 129:33 hours:minutes. Changes in body mass (including body fat and lean body mass), foot volume, total body water, and laboratory measurements were assessed. Food and fluid intake during rest and competing were recorded, and energy and fluid turnovers were estimated. During the ten stages, the volume of the feet increased, percentage body fat decreased, creatinine and urea levels increased, hematocrit and hemoglobin values decreased, and plasma [Na+] remained unchanged. The increase in foot volume was significantly and positively related to fluid intake during the stages. The poststage volume of the foot was related to poststage total body water, poststage creatinine, and poststage urea. This case report shows that the volume of the foot increased during the ten stages, and the increase in volume was significantly and positively related to fluid intake during the stages. Furthermore, the poststage volume of the foot was related to poststage total body water, poststage creatinine, and poststage urea. The continuous feet swelling during the race was most probably due to a combination of a high fluid intake and a progressive decline in renal function (ie, continuous increase in creatinine and urea), leading to body fluid retention (ie, increase in total body water).

    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.

    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.

  1. Temporal patterns in count-to-ten fetal movement charts and their associations with pregnancy characteristics: a prospective cohort study

    Full Text Available Abstract Background Fetal movement counting has long been suggested as a screening tool to identify impaired placental function. However, quantitative limits for decreased fetal movement perform poorly for screening purposes, indicating the need for methodological refinement. We aimed to identify the main individual temporal patterns in fetal movement counting charts, and explore their associations with pregnancy characteristics. Methods In a population-based prospective cohort in Norway, 2009–2011, women with singleton pregnancies counted fetal movements daily from pregnancy week 24 until delivery using a modified "count-to-ten” procedure. To account for intra-woman correlation of observations, we used functional data analysis and corresponding functional principal component analysis to identify the main individual temporal patterns in fetal movement count data. The temporal patterns are described by continuous functional principal component (FPC curves, with an individual score on each FPC for each woman. These scores were later used as outcome variables in multivariable linear regression analyses, with pregnancy characteristics as explanatory variables. Results Fetal movement charts from 1086 pregnancies were included. Three FPC curves explained almost 99% of the variation in the temporal data, with the first FPC, representing the individual overall counting time, accounting for 91% alone. There were several statistically significant associations between the FPCs and various pregnancy characteristics. However, the effects were small and of limited clinical value. Conclusions This statistical approach for analyzing fetal movement counting data successfully captured clinically meaningful individual temporal patterns and how these patterns vary between women. Maternal body mass index, gestational age and placental site explained little of the variation in the temporal fetal movement counting patterns. Thus, a perceived decrease in fetal movement should not be attributed to a woman’s basic pregnancy characteristics, but assessed as a potential marker of risk.

    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.

    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.

  12. The effect of manganese on the central nervous system. On the basis of ten cases with hyperintensities in the globus pallidus and a part of the brainstem on T1-weighted magnetic resonance imaging

    International Nuclear Information System (INIS)

    We examined the effect of manganese (Mn) on the central nervous system, on the basis of ten cases with hyperintensities in the globus pallidus and a part of the brainstem on T1-weighted magnetic resonance imaging (MRI). These cases were divided into three groups; four cases with liver dysfunction, three cases with intravenous infusion containing Mn and three cases without any specific factor. Mn levels were measured in serum, whole blood and cerebrospinal fluid (CSF). As a result, their serum and CSF Mn levels were significantly higher (P<0.05 and P<0.01, respectively) than those of the control subjects, while their whole blood Mn levels were not significantly different. Single photon emission computed tomography demonstrated a decrease of the cerebral blood flow in the frontal lobe in four cases with the hyperintensities and in one of them the decrease improved after the disappearance of the hyperintensity. Oculogyric crisis in one case with intravenous infusion containing Mn and dystonia in one case without any specific factor also improved, when the hyperintensities disappeared. In the cases with T1-weighted MRI hyperintensities, it is important to measure serum and CSF Mn levels as well as to observe psychiatric and neurological symptoms. (author)

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

    The results of 32 cases studied lead us to the conclusion that erythema nodosum's investigation routine is very important, once in our retrospective study, the percentage of cases of unknown etiology was 69.4%, and in this prospective study it is 21.8%. In 10 cases (31.2%), more than one causing agent was suspected. Infections (bacterial, helminthic, fungal, by protozoa) were diagnosed in 26 cases, streptococcal infection having predominated (12 cases). Drugs-dipirone, aspirin, anovulatory--were suspected as causing agents in 13 cases. The association of erythema nodosum and histoplasmosis capsulata is described for the first time in Brazil. We consider erythema nodosum to be a complex syndrome which should be regarded as a manifestation of underlying diseases. The fact that all 32 subjects were women, 26 of them during menacme, suggests that particular hormonal media may favor the action of various processes (infections and drugs), precipitating erythema nodosum's clinical picture.

    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.

    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.

    Background. To control the malaria mortality, the global and national communities have worked together and produced impressive results in the world. Some of the Asian counties' malaria mortality rate is more compared to countries with high health facilities around the world. This paper's main aim is to describe trend of malaria cases and mortality in 10 Asian countries using the World Health Organization data. Methods. Malaria mortality data was collected systematically from WHO and UN database for the period 2006–2011. We estimated malaria mortality by age and countries. We also explored the dynamic relationships among malaria death rate, total populations, and geographical region using a map. During 2006–2011, the average malaria death per 10,000 population of all ages was 0.239 (95% CI 0.104 to 0.373), of children aged less than 5 year 1.143 (0.598 to 1.687), and of age greater than 5 years 0.089 (0.043 to 0.137) in Asian countries. Malaria prevalence per 10,000 populations steadily decreased from 486.7 in 2006 to 298.9 in 2011. Conclusion. The findings show that malaria mortality is higher for children aged less than 5 years compared with with adults selected in Asian countries except Sri Lanka. PMID:26693382

  2. Outage management: A case study

    International Nuclear Information System (INIS)

    Outage management issues identified from a field study conducted at a two-unit commercial pressurized water reactor (PWR), when one unit was in a refueling outage and the other unit was at full power operation, are the focus of this paper. The study was conduced as part of the US Nuclear Regulatory Commission's (NRC) organizational factors research program, and therefore the issues to be addressed are from an organizational perspective. Topics discussed refer to areas identified by the NRC as critical for safety during shutdown operations, including outage planning and control, personnel stress, and improvements in training and procedures. Specifically, issues in communication, management attention, involvement and oversight, administrative processes, organizational culture, and human resources relevant to each of the areas are highlighted by example from field data collection. Insights regarding future guidance in these areas are presented based upon additional data collection subsequent to the original study

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

    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.

  13. Modifiable cardiovascular disease risk factors as predictors of dementia death: pooling of ten general population-based cohort studies

    Science.gov (United States)

    2014-01-01

    Background With drug treatment for dementia being of limited effectiveness, the role of primary prevention, in particular the predictive value of modifiable cardiovascular disease risk factors, may warrant exploration. The evidence base is, however, characterised by discordant findings and is modest in size. Accordingly, we examined the association of modifiable cardiovascular disease risk factors with dementia death. Design and methods We pooled raw data from 10 UK general population-based prospective cohort studies within the context of an individual participant meta-analysis. Results A total of 103,764 men and women were followed up for a mean of 8 years giving rise to 443 dementia-related deaths and 2612 cardiovascular disease deaths. Cardiovascular disease mortality was, as anticipated, associated with the full range of risk factors under study, including raised blood pressure, smoking, diabetes, physical inactivity. By contrast, dementia death was related to very few of the cardiovascular disease risk factors: of those classified as modifiable, only smoking was associated with a raised risk and higher levels of non-HDL with a lower risk. Conclusions In the present individual participant meta-analysis, there was limited evidence that cardiovascular disease risk factors were related to dementia death. PMID:24886432

    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.

    2012-03-01

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

    Full Text Available Beat Knechtle,1 Matthias Alexander Zingg,2 Patrizia Knechtle,1 Thomas Rosemann,2 Christoph Alexander Rüst2 1Gesundheitszentrum St Gallen, St Gallen, 2Institute of Primary Care, University of Zurich, Zurich, Switzerland Abstract: Recent studies investigating ultraendurance athletes showed an association between excessive fluid intake and swelling of the lower limbs such as the feet. To date, this association has been investigated in single-stage ultraendurance races, but not in multistage ultraendurance races. In this case study, we investigated a potential association between fluid intake and feet swelling in a multistage ultraendurance race such as a Deca Iron ultratriathlon with ten Ironman triathlons within 10 consecutive days. A 49-year-old well-experienced ultratriathlete competed in autumn 2013 in the Deca Iron ultratriathlon held in Lonata del Garda, Italy, and finished the race as winner within 129:33 hours:minutes. Changes in body mass (including body fat and lean body mass, foot volume, total body water, and laboratory measurements were assessed. Food and fluid intake during rest and competing were recorded, and energy and fluid turnovers were estimated. During the ten stages, the volume of the feet increased, percentage body fat decreased, creatinine and urea levels increased, hematocrit and hemoglobin values decreased, and plasma [Na+] remained unchanged. The increase in foot volume was significantly and positively related to fluid intake during the stages. The poststage volume of the foot was related to poststage total body water, poststage creatinine, and poststage urea. This case report shows that the volume of the foot increased during the ten stages, and the increase in volume was significantly and positively related to fluid intake during the stages. Furthermore, the poststage volume of the foot was related to poststage total body water, poststage creatinine, and poststage urea. The continuous feet swelling during the race was most probably due to a combination of a high fluid intake and a progressive decline in renal function (ie, continuous increase in creatinine and urea, leading to body fluid retention (ie, increase in total body water.

Themean age at the time of diagnosis was 38.6 years (range, birth to 67 years.The male to female ratio was 3 to 2. In most cases, EAH arose as a singlelesion on a lower extremity. The symptoms and signs most commonly associated with EAH were pain (60%, hypertrichosis (13.3%, itching (13.3%and hyperhidrosis (6.7%. Additional pathological findings included hemangioma (13.3%, verrucous hemangioma (6.7%, arteriovenous malformation(6.7%, and angiokeratoma (6.7%. None of the patients experienced spontaneous regression of the lesions before excision. Excisions were done in onepatient under general anesthesia, and ten patients with local anesthesia. Fourpatients were kept under observation. Tumor recurrences were noted in twoout of the eleven patients whose lesions were excised.Conclusion: Compared with cases in the literature, we found additional histopathologicalfindings and an increased tumor recurrence risk in our cohort. EAH remainsa benign and uncommon hamartomatous condition. Further multi-center, retrospective studies with larger case numbers are needed to better characterizethe disease presentation in Asian populations.

    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.

    Ground-source heat pump systems are one of the promising new energy technologies that has shown rapid increase in usage over the past ten years in the United States. These systems offer substantial benefits to consumers and utilities in energy (kWh) and demand (kW) savings. The purpose of this study was to determine what existing monitored data was available mainly from electric utilities on heat pump performance, energy savings and demand reduction for residential, school and commercial building applications. In order to verify the performance, information was collected for 253 case studies from mainly utilities throughout the United States. The case studies were compiled into a database. The database was organized into general information, system information, ground system information, system performance, and additional information. Information was developed on the status of demand-side management of ground-source heat pump programs for about 60 electric utility and rural electric cooperatives on marketing, incentive programs, barriers to market penetration, number units installed in service area, and benefits.

    We sought to evaluate the contribution of various modifiable risk factors to the partial population attributable risk (PARp) for diabetes in an Asian Indian population. Of a cohort of 3589 individuals, representative of Chennai, India, followed up after a period of ten years, we analyzed data from 1376 individuals who were free of diabetes at baseline. A diet risk score was computed incorporating intake of refined cereals, fruits and vegetables, dairy products, and monounsaturated fatty acid. Abdominal obesity was found to contribute the most to incident diabetes [Relative Risk (RR) 1.63(95%CI 1.21-2.20)]; (PARp 41.1% (95%CI 28.1-52.6)]. The risk for diabetes increased with increasing quartiles of the diet risk score [highest quartile RR 2.14(95% CI 1.26-3.63)] and time spent viewing television [(RR 1.84(95%CI 1.36-2.49] and sitting [(RR 2.09(95%CI 1.42-3.05)]. The combination of five risk factors (obesity, physical inactivity, unfavorable diet risk score, hypertriglyceridemia and low HDL cholesterol) could explain 80.7% of all incident diabetes (95%CI 53.8-92.7). Modifying these easily identifiable risk factors could therefore prevent the majority of cases of incident diabetes in the Asian Indian population. Translation of these findings into public health practice will go a long way in arresting the progress of the diabetes epidemic in this region. PMID:26044609

  9. 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)

    2011-01-01

    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. PMID:21676231

  3. 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

    Ma-Zi-Ren-Wan (MZRW) is a classic Chinese formula which has been used to treat human constipation in China for over 2000 years. In order to make good and rational use of this formula in the future, this paper presents the first attempt to track the pharmacokinetic features of MZRW in rat using rapid and sensitive ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). Ten chemical components of MZRW, namely, rhein, emodin, aloe emodin, hesperidin, naringin, amygdalin, albiflorin, paeoniflorin, magnolol and honokiol, were simultaneously determined in rat plasma after a single oral administration (10g/kg body weight) of MZRW to rats. Geniposide and liquiritin were used as internal standards. The separation was performed on a Waters ACQUITY BEH C18 column (100mm×2.1mm, 1.7?m). The detection was conducted by multiple-reaction monitoring (MRM) in negative ionization mode. Two highest abundant MRM transitions without interference were optimized for each analyte. This method was well validated in terms of linearity, precision, accuracy, recovery, matrix effect and stability. All calibration curves had good linearity (r(2)>0.995) over the concentration range from 3.9 to 125.0ng/mL for emodin, 3.9-500.0ng/mL for amygdalin, 2.0-4000.0ng/mL for naringin and hesperidin, 3.9-2000.0ng/mL for magnolol, 7.8-2000.0ng/mL for rhein and 3.9-4000.0ng/mL for albiflorin, paeoniflorin, aloe emodin and honokiol. The intra-day and inter-day precision (relative standard deviation) was within 15%, the accuracy (relative error) ranged from -13.6% to 15.1%, and the lower limit of quantification in plasma ranged between 2.0ng/mL and 7.8ng/mL. Extraction recovery, matrix effect and stability were satisfactory. The validated method was successfully applied to a pharmacokinetic study of these ten compounds after oral administration of MZRW to rats. The pharmacokinetic parameters of each compound can facilitate clinical studies in the future. PMID:26231677

  5. 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

    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.

    1999-03-01

    We describe several of the case studies in the NEOS Guide, a site on the World Wide Web that contains informational and educational material about optimization. These studies show how optimization relates to practical applications. They guide the user through relevant details of the application, formulation, solution, and interpretation of the results. The studies use interactivity to build intuition, allowing users to define their own problems and examine the corresponding solutions. The studies can be used for assignments in optimization and operations research courses and as small self-guided units equivalent to one or two lecture classes.

  4. A case-control study of lung cancer relative to domestic radon exposure

    International Nuclear Information System (INIS)

    Public concern was expressed regarding the possibility of adverse health effects with the disposal of radioactive waste in Port Hope, Ontario. A case-control study was carried out to estimate the relative importance of domestic radon gas exposure in the causation of lung cancer in the town over a ten-year period. Twenty-seven cases met the entry criteria. Statistical analyses of results did not provide conclusive results that linked an increased risk of lung cancer and elevated domestic alpha radiation levels, when all factors were considered. However, a very strong association was demonstrated between cigarette smoking and lung cancer. (author)

  5. 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.

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

    Directory of Open Access Journals (Sweden)

    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.

  10. Waiting Lists for Radiation Therapy: A Case Study

    Directory of Open Access Journals (Sweden)

    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.

  18. L’utilisation du TENS en physiothérapie : la situation particulière des soins palliatifs oncologiques

    Directory of Open Access Journals (Sweden)

    Laliberté, Maude

    2012-11-01

    Full Text Available Trans-cutaneous electrical nerve stimulation (TENS is a treatment against pain that uses the application of an electric current. Some studies suggest that TENS would reduce the pain associated with certain types of cancer and this treatment is regularly used in therapy in contexts of interdisciplinary practice specializing in palliative oncology. However, the use of TENS in cancer cases is a matter of controversy, and its application is contraindicated by Canadian standards governing the practice of physiotherapy. This article aims to present, through a case study, some principles to guide decision making regarding the choice of this therapy in cases of cancer. Scientific evidence, standards of practice and ethical principles that should guide the choice of therapy are discussed. The use of TENS therapy in palliative care is a paradigmatic example of a common situation: the weighing by health care professionals of the benefits and potential costs, such as potential adverse effects of treatment. In the case of TENS, the benefits are associated with the reduction of pain, while a potential adverse effect would increase tumour proliferation. This difficult calculation has implications for the various stakeholders such as patients and health professionals.

  19. 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.

    1996-01-01

    The subject of the study was the feasibility of the quality assurance of hazard and operability studies (HAZOPs) within the context of their possible usage in Offshore Safety Cases (OSCs). HAZOP is one technique that could be put forward in partial fulfilment of the requirement in the Offshore Installations (Safety Case) Regulation 1992 [1] to identify all hazards with the potential to cause a major accident, but its use is not mandatory. The study was carried out in three phases. The framework within which quality assurance of HAZOP might be carried out was explored; in addition, experience from Voluntary Safety Cases (VSCs) was reviewed. The current practices and views of a sample of ten operating companies were surveyed. Finally, proposals for a means of HAZOP QA were considered and the basis of a scheme for HAZOP QA was developed.

    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.

Dit is 'n voortsetting van 'n soortgelyke gevallestudie (Madiba, Mpha-hlele en Kganyago 2003 wat 'n poging was om Noord-Sothokookterme te versamel en aan te bied. Gevallestudie I bestaan uit die name van gereedskap, bestanddele, en die prosesse betrokke by die voorbereiding van kulturele geregte. Met altwee hierdie gevallestudies was die bedoeling om die geleenthede te gebruik wat hulleself aanbied vir die bewaring en bestendiging van Noord-Sotho, insluitende die uitbreiding van sy korpora om die nasionale woordeboeksamestellingsprosesse te ondersteun. Die gevallestudiemetodologie was baie nuttig vir die doeleindes van hierdie projek en die konteks waarin dit onderneem is. Dit beoog om 'n model te verskaf vir die versameling en aanbieding van Noord-Sothoterminologie wat andersins skaars toeganklik sou gewees het.

  4. Ten Famous Double Stars

    Argyle, Bob; Argyle, R. W.

    In this chapter we move out from the Sun and look at some of the neighbouring double and multiple stars which have been observed for centuries. In some cases there are still secrets to be revealed. The beauty of a sunset on Earth has inspired poets and artists for millennia—what must it be like when there is not one sunset but two or more with each sun glowing in a different color. The chiaroscuro would be impressive to say the least. Not all double and multiple systems have different colors—some contain stars of essentially the same spectral class and therefore color (Table 9.1).

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".

  7. Ten Challenges for Decision Neuroscience

    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.

    Full Text Available This research presents a retrospective study of 62 cases of mycetoma in Iran that were diagnosed clinically and microbiologically from 1972 to 2005. In 1972 mycetoma has been first report in Iran by medical mycology department of Tehran University. We retrospectively compared the overall prevalence of mycetoma and the prevalence of infective agent in Iran during 33 years. In this study age, sex, job, infective agent and anatomical site of infection have been considered. Retrospective analysis of the records revealed that the ratio of actinomycetoma and eumycetoma was 42:20 that differed significantly (p < 0.01. Actinomadura madurae (n = 11 in actiomycetoma and Psudallescheria boydii (n = 9 in eumycetoma were predominant agents. The male to female ratio was 41:21 and the peak age for infection was between 40-50 years old but there is no a significant differences between age groups (p > 0.05 and the earliest age of onset was 18 and the latest 65.The single most common site of infection is foot but generally hand and other limbs can infected and 54.4% of infected area was in palm and disease can infected other area with less frequency. A total of 49 cases were pedal mycetoma and 13 cases were in extra pedal areas. The results show that farmers with 45.2% are at greater occupation risk of mycetoma (p < 0.01.

  11. Case-control studies of screening procedures.

    1991-01-01

    Case-control studies of different screening procedures have been reported. Cases of the detectable disease, and controls without the disease, were compared with respect to their previous screening histories. Measures of the protective value of the test were calculated from the difference. The inductive basis of these studies is re-examined and it is concluded that all claims to have measured the protective value of a screening test through such means are potentially or actually flawed. The reasons for the inductive failures are: (a) The ratio between the retrospective screening frequencies depends critically upon unmeasured parameters other than procedural efficacy; the ratio is therefore not capable on its own of providing an estimate of the protection afforded: (b) Almost all screens among reported case and control groups have been negative, and it is a matter of prior fact that a negative test does not protect anyone. Only the positive tests protect. Direct analogies with drug and vaccine trials, from which the concept of a 'protective value' originates, are therefore false. PMID:2008504

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

    Terahertz (THz) spectroscopy and imaging is a non-destructive, non-contact, non-invasive technology emerging as a tool for the analysis of cultural heritage. THz Time Domain Spectroscopy (TDS) techniques have the ability to retrieve information from different layers within a stratified sample, that enable the identification of hidden sub-layers in the case of paints and mural paintings. In this paper, we present the THz TDS2 system developed in the European Commission's 7th Framework Program project CHARISMA [grant agreement no. 228330]. Bespoke single processing algorithms; including a deconvolution algorithm can be deployed to increase the resolution and the global performance of the system. The potential and impact of this work is demonstrated through two case studies of mural paintings, where the capability to reveal the stratigraphy of the artworks is demonstrated.

    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.

    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.

  19. Case studies in using alternative sampling technologies

    International Nuclear Information System (INIS)

    Traditionally, site assessments for delineating petroleum hydrocarbon releases have been conducted in several phases. One way to improve the traditional assessment and remedial investigation methodology is to utilize alternative sampling techniques such as drive point sampling, combined with on-site field analytical methods. There are several drive point sampling technologies which have been used successfully in the past several years to collect both soil and groundwater samples. These drive point techniques include the Geoprobe trademark, Hydropunch trademark, Cone Penetrometer Testing (CPT) and KV trademark Sampling System. Utilized in combination with an on-site mobile laboratory equipped to conduct headspace analysis by EPA method 3810, these drive point sampling methods provide immediate, real-time data at a lower cost per data point. This paper presents three case studies in utilizing the Geoprobe trademark as an alternative sampling technology to gather both soil and groundwater data to delineate site contamination and provide for more informed, remedial solutions. In two of the cases (retail service stations), remediation by groundwater pump and treat had been on-going for several years with little remedial progress. The use of the alternative sampling technologies provided the needed information to expedite site clean-up. The remaining site is a petroleum refining facility where an active recovery system was planned. In this case, the data provided through the expedited assessment provided imperative design information

    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.

    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.

    Full Text Available Privacy is a complex social process that will persist in one form or another as a fundamental feature of software engineering. For successful privacy aware engineering, it is critical to guarantee the alignment and compliance among privacy artifacts emerging during software development process. In this paper, we propose a privacy compliance engineering flow in which we investigate the involved necessary privacy artifacts and discuss their alignment, refinement, and compliance verification. Within an exemplary case study, we identify the privacy artifacts introduced in the refinement process and analyze their compliance verification.

    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

  11. A postural 'stressed' cerebral HMPAO case study

    International Nuclear Information System (INIS)

    Full text: This case study represents an example of the utility of postural hypoperfusion stressed HMPAO SPECT. An elderly woman of 78 with a long history of giddiness was referred to our laboratory for examination of possible cerebral ischaemia. She had recurrent dizzy episodes, sometimes posture related, over the past few years and had suffered several falls. Cerebral DSA revealed minimal disease. CT scans were reported as normal. Carotid duplex Doppler studies revealed bilateral plaque disease in the carotid bulbs extending to the origins of the ICAs which were not significant stenoses. Postural symptoms were induced by standing the patient up rapidly and HMPAO was administered at the same time. A SPECT scan of the brain was performed. Quantitative analysis showed a left to right decrease of 10.8% in the temporo-occipital area, 5.6% in the temporo-parietal area and 2.5% in the cerebellar and parietal areas. Images revealed moderately reduced tracer concentration in the left half of the cerebellum and the left occipital region extending as far forward as the temporo-parietal region A repeat HMPAO SPECT scan without stress was normal. This would appear to indicate reversible ischaemia in the left posterior region, and is consistent with the reported symptoms. This case illustrates the usefulness of HMPAO in the diagnosis of reversible cerebral ischaemia

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.

    Bristow, S E; Hasan, S T; Neal, D E

    1996-01-01

    To ascertain the mode of action and benefits of transcutaneous electrical nerve stimulation (TENS) in detrusor overactivity, stress incontinence and interstitial cystitis, an English-language literature search using Medline (1984-1995) was undertaken with detrusor instability, incontinence, interstitial cystitis, neuromodulation, transcutaneous electrical nerve stimulation and urodynamics as keywords and the material so identified was reviewed. The mode of action of TENS and optimal stimulation parameters in bladder dysfunction remain unclear. Lack of strict selection criteria and deficient reporting of subjective and objective outcomes precluded full assessment of therapeutic efficacy. A beneficial effect was evident in some studies of detrusor overactivity and interstitial cystitis. A trial of TENS in detrusor overactivity and interstitial cystitis refractory to conventional therapy would seem justified. Continued experimental research and further clinical studies will lead to refinement of the treatment modality. PMID:10895802

    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.

    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.

    When the United States Supreme Court approved the reinstatement of the death penalty in the United States in 1976, it did so based on the promise of new safeguards against comparative excessiveness and relative disproportionality resulting from jury sentencing in capital cases. As Justice Stevens noted in 2008, one of these safeguards – meaningful appellate review of death sentences – is, in practice, non-existent. This thesis examines the use of this purported safeguard by the Ohio Supre...

    Full Text Available Introduction: Vascular tumors show a broad variety of morphological appearances and cilinical behavior, the lesions are ranging from benign hemangiomas to intermediate lesion, which are locally aggressive, to highly malignant angiosarcoma. There is also the grey zone between true neoplasia and hamartoma, which makes difficulty in histopathological assessment. It is also important to decide the degree of malignancy as it can strongly influence the choice of treatment and prognosis. Methodology: Hundred cases of vascular tumors received at the department of pathology, medical college and SSG hospital, Baroda have been studied with a view to carrying out a histopathological analysis. Results: mploying modified Enzinger’s classification (2001 the break up of 100 cases was as follows : 37 – capillary hemangiomas, 26 – granuloma pyogenicum, 15 – cavernous hemangiomas, 07 – lymphangiomas, 04 – masson’s hemangiomas (papillary endothelial hyperplasia, 03 – epithelioid hemangiomas, 03 – lymphangiomas circumscriptum, 01 – cystic hygroma, 01 – spindle cell hemangioendothelioma, 01 – epithelioid hemangioendothelioma, 01 – glomus tumor, 01 – angiosarcoma. Majority of vascular tumors were benign, more common in children and young adults, most common sites were head and neck, which required only local surgical excision. Conclusion: Malignant and intermediate tumors formed as extremely small proportion of vascular tumors, which should be treated aggressively and closely followed up.

    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.

    Full Text Available Abstract BACKGROUND: Lichen planus is considered to be the most common dermatological disease involving the oral mucosa. OBJECTIVE: To investigate the profile, clinical features, and the presence of dysplasia and candidiasis in patients with oral lichen planus. METHODS: A total of 21 patients were s [...] elected from 258 patients at risk for oral cancer development. RESULTS: Most of the patients were white (76,2%), female (66,6%), with mean age of 58.8 years. Eight were smokers and seven were alcohol consumers. The buccal mucosa was the most affected site, followed by the tongue and the gingiva. The reticular pattern was the most common appearance. Histopathology depicted dysplasia in nine cases and cytopathology was positive for Candida in eight cases in the first appointment. CONCLUSION: Our data are similar to the literature. Cytopathology was important for the diagnosis of candidiasis. Although the presence of dysplasia was verified, further studies are necessary to clarify the importance of this finding.

    The holographic principle has taught us that, as far as their entropy content is concerned, black holes in $(3+1)$-dimensional curved spacetimes behave as ordinary thermodynamic systems in flat $(2+1)$-dimensional spacetimes. In this essay we point out that the opposite behavior can also be observed in black-hole physics. To show this we study the quantum Hawking evaporation of near-extremal Reissner-Nordstr\\"om black holes. We first point out that the black-hole radiation spectrum departs from the familiar radiation spectrum of genuine $(3+1)$-dimensional perfect black-body emitters. In particular, the would be black-body thermal spectrum is distorted by the curvature potential which surrounds the black hole and effectively blocks the emission of low-energy quanta. Taking into account the energy-dependent gray-body factors which quantify the imprint of passage of the emitted radiation quanta through the black-hole curvature potential, we reveal that the $(3+1)$-dimensional black holes effectively behave as p...

    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

A government organization has been developing 'Circuits Analyzers', and 'Hacker-Tracking Program' and is struggling to track down sneakers. In this report, we analyze the contents of the cases where the communication network has been invaded, from the past up until now in Korea. This report also contains the result of a study on E-mail security, for the protection of KAERI Integrated Management Information System under which utilizes the CALS concepts and web services.

    2012-09-01

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

  12. Social Set Analysis : Four Demonstrative Case Studies

    DEFF Research Database (Denmark)

    2015-01-01

    This paper argues that the basic premise of Social Network Analysis (SNA) -- namely that social reality is constituted by dyadic relations and that social interactions are determined by structural properties of networks-- is neither necessary nor sufficient, for Big Social Data analytics of Facebook or Twitter data. However, there exist no other holistic computational social science approach beyond the relational sociology and graph theory of SNA. To address this limitation, this paper presents an alternative holistic approach to Big Social Data analytics called Social Set Analysis (SSA). Based on the sociology of associations and the mathematics of classical, fuzzy and rough set theories, this paper proposes a research program. The function of which is to design, develop and evaluate social set analytics in terms of fundamentally novel formal models, predictive methods and visual analytics tools for Big Social Data. Four demonstrative case studies, employing SSA, covering the range of descriptive, predictive, visual and prescriptive analytics are presented and briefly discussed.

    2008-01-01

    Full Text Available The Fibromyalgia is a syndrome of pain and chronic diffuse, characterized by the presence of at least 11 of 18 points called anatomically specific tender points, painful on palpation. As the pain diffuse the main symptom of fibromyalgia. The current treatment is focused mainly to the reduction of symptoms. Physiotherapy has an important role in improving the control of pain. This study aimed to verify the effectiveness of the main TENS of low frequency and high intensity in modulating pain of tender points of patients with fibromyalgia. For this was a case study of patient R. S. S., 38-year-old female carrier of the syndrome of fibromyalgia attended school in the clinic of the Faculty of Integrated Ceará (FISIOFIC. The patient was treated with the TENS-pain Acupuncture points in a total of twelve care and pain assessed before starting treatment and after three attendants. There was a significant reduction in pain intensity at 77.7% of the tender points in the second evaluation and 88.8% of the points in the other assessments. It was concluded that there was a reduction in the pain of tender points of the patient showing the analgesia promoted by TENS, so it should be used as a complementary treatment programs associated with other treatments and also served as a good technique to locate the tender points

    Full Text Available Abstract Background Biological databases and pathway knowledgebases are proliferating rapidly. We are developing software tools for computer-aided hypothesis design and evaluation, and we would like our tools to take advantage of the information stored in these repositories. But before we can reliably use a pathway knowledgebase as a data source, we need to proofread it to ensure that it can fully support computer-aided information integration and inference. Results We design a series of logical tests to detect potential problems we might encounter using a particular knowledgebase, the Reactome database, with a particular computer-aided hypothesis evaluation tool, HyBrow. We develop an explicit formal language from the language implicit in the Reactome data format and specify a logic to evaluate models expressed using this language. We use the formalism of finite model theory in this work. We then use this logic to formulate tests for desirable properties (such as completeness, consistency, and well-formedness for pathways stored in Reactome. We apply these tests to the publicly available Reactome releases (releases 10 through 14 and compare the results, which highlight Reactome's steady improvement in terms of decreasing inconsistencies. We also investigate and discuss Reactome's potential for supporting computer-aided inference tools. Conclusion The case study described in this work demonstrates that it is possible to use our model theory based approach to identify problems one might encounter using a knowledgebase to support hypothesis evaluation tools. The methodology we use is general and is in no way restricted to the specific knowledgebase employed in this case study. Future application of this methodology will enable us to compare pathway resources with respect to the generic properties such resources will need to possess if they are to support automated reasoning.

  17. 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.

  18. ISOE: Ten years of experience

    International Nuclear Information System (INIS)

    The Information System on Occupational Exposure (ISOE), sponsored by the OECD Nuclear Energy Agency and the IAEA, was created in 1992 to facilitate information exchange between radiation protection experts from both operating organizations and national regulatory authorities and to enhance international co-operation on worker protection at nuclear power plants. The ISOE programme offers the world's largest database on occupational radiation exposure due to nuclear power plants covering, in 2001, 93% of the commercial power reactors in the world. In addition to providing the basis for analyses of dose trends, benchmarking and detailed studies, the ISOE also offers a system for rapid communication of radiation protection information and a forum for discussing occupational radiation exposure management issues through ISOE workshops and symposiums, organized annually. This paper is based on a report, published in 2002, summarizing the experience gained from ten years' of developing the ISOE and containing comments from participants on their experience with the system. Growing use of improved work management procedures, developed and published through the ISOE, has contributed to the downward trend in the annual average collective dose per reactor. The impact of a steam generator replacement on the evolution of this dose has also been demonstrated. To maintain or even further reduce the already low levels of occupational exposure, the ISOE needs to be regularly used and further promoted by its participants. In future, the ISOE can also play an important role in the decommissioning and dismantling of nuclear power plants. (author)

  20. Bilingual education in Slovakia: A Case Study

    Directory of Open Access Journals (Sweden)

    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.

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

    Directory of Open Access Journals (Sweden)

    Graeme Shanks

    2002-11-01

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

    Rosa, Morales.

    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.

    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 ...

On its structure, one group stands out, the families who live around the academic unities of Porangabussu Campus. It aims to apprehend the social representations about the lifestyle of families with approach on their life activities. The case study, which was made with 30 families, happened from September 2006 to March 2007, and were used: semi-strutured interview; participative observation; photography of place's campus, and the working out of a testimony about the choice. It was used the Bardin Contents Analysis (1977 and the Robert Ott approach (1997 for photographs. The representations were organized in five categories, being the main representation, the lack of infra-structure and security on the campus. Based on the Ropper, Logan and Tierney Nursing Model (1990, it was found that all life activities were changed and the most affected were: safe environment, 23.9%; breath, work and distraction, with 13, 3% each, and sleep, 9.6%. About the photography's technique, the Structure of the Campus (33.7% and the aesthetics (37.6% were the most represented. The study allowed the knowledge of the reality experienced by families and the need for changes in this place.

    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.

  12. Bayesian inference in physics: case studies

    Science.gov (United States)

    Dose, V.

    2003-09-01

    This report describes the Bayesian approach to probability theory with emphasis on the application to the evaluation of experimental data. A brief summary of Bayesian principles is given, with a discussion of concepts, terminology and pitfalls. The step from Bayesian principles to data processing involves major numerical efforts. We address the presently employed procedures of numerical integration, which are mainly based on the Monte Carlo method. The case studies include examples from electron spectroscopies, plasma physics, ion beam analysis and mass spectrometry. Bayesian solutions to the ubiquitous problem of spectrum restoration are presented and advantages and limitations are discussed. Parameter estimation within the Bayesian framework is shown to allow for the incorporation of expert knowledge which in turn allows the treatment of under-determined problems which are inaccessible by the traditional maximum likelihood method. A unique and extremely valuable feature of Bayesian theory is the model comparison option. Bayesian model comparison rests on Ockham's razor which limits the complexity of a model to the amount necessary to explain the data without fitting noise. Finally we deal with the treatment of inconsistent data. They arise frequently in experimental work either from incorrect estimation of the errors associated with a measurement or alternatively from distortions of the measurement signal by some unrecognized spurious source. Bayesian data analysis sometimes meets with spectacular success. However, the approach cannot do wonders, but it does result in optimal robust inferences on the basis of all available and explicitly declared information.

  13. 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 The European refugee problem has grown dramatically in the last few months, putting a considerable amount of pressure on the European countries. Not only are they facing migrants from North Africa, but from the Middle East as well.In March 2011 the Arab Spring has reached Syria, causing a huge number of Syrians to flee their country and seek asylum in Turkey, and possibly going further to the EU. The refugees who fled Syria as well as those who are leaving North Africa (mostly the failed state of Libya are aiming to reach European soil, but Italy, Greece or Turkey is not ready to handle the amount of refugees. The cooperation of the Mediterranean countries and Europe has not been able to slow down the flow of refugees, and the Mediterranean and Aegean seas have become dangerous routes for the desperate migrants who attempt the sea-crossing. In my analysis I would like to highlight the role of the so-called elements of ‘soft power’ in the way of dealing with the refugee problem. According to my hypothesis, the issue can’t be successfully addressed using only the means of the ‘soft power’. No real solution for the crisis has been offered yet, and I would like to give case studies of the different ways of dealing with the problem – inside (Greece, Italy and outside (Turkey of the European Union.

    Full Text Available The paper is based on the preliminary results of the research project "Deindustrialization and under-development in the Romanian Transition. Individual/Collective Strategies and Reply Policies. Case study: Valea Jiului", that will be done within the POSDRU project "Plural and interdisciplinary in doctoral and post-doctoral programs". This paper intends to analyze the complex relation between economic development, social development and modernization. The basic hypothesis of the proposed analysis is that the economic development is not an irreversible process not even when it leads to social development as part of a modernizing program. Valea Jiului represents an example of how the economic and social development built on weak basis, become unsustainable. The collapse of this weak basis initiated after 1989 when the economy and the society changed and after a transition period produced a major negative social impact started with the restructuring of the mining. In less than 10 months, the number of the miners was reduced to half and the reduction continued. Today in Valea Jiului is only 15 % of the number of employees in 1989. The social effects of the mining restructuring were at communitarian level the underdevelopment, return to pre-modern occupations like the subsistence agriculture. A good example that will be deeply analyzed in this paper is the town Aninoasa, the first Romanian town in insolvency since 2013.

    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.

    Although data visualization is a powerful tool in Earth science, the resulting imagery is often complex and difficult to interpret for non-experts. Students, journalists, web site visitors, or museum attendees often have difficulty understanding some of the imagery scientists create, particularly false-color imagery and data-driven maps. Many visualizations are designed for data exploration or peer communication, and often follow discipline conventions or are constrained by software defaults. Different techniques are necessary for communication with a broad audience. Data visualization combines ideas from cognitive science, graphic design, and cartography, and applies them to the challenge of presenting data clearly. Visualizers at NASA's Earth Observatory web site (earthobservatory.nasa.gov) use these techniques to craft remote sensing imagery for interested but non-expert readers. Images range from natural-color satellite images and multivariate maps to illustrations of abstract concepts. I will use imagery of the eruption of Iceland's Eyjafjallajökull volcano as a case study, showing specific applications of general design techniques. By using color carefully (including contextual data), precisely aligning disparate data sets, and highlighting important features, we crafted an image that clearly conveys the complex vertical and horizontal distribution of airborne ash.

  19. CFD analysis for road vehicles - case study

    2011-09-01

    Full Text Available This is a case study on the influence of the lower part of road vehicles on the global drag characteristics. Reducing overall drag by redesigning the lower part of the road vehicles has a potential of almost 20% in the overall drag breakdown, mainly due to the viscous effects and the fluidic interaction of the flow under the car with the typical bluff body flow pattern behind the vehicle. A special parameterization is proposed for the global shape of the sedan car, with respect to the lower part of the body, taking into account most of the specificities of the system. For such a complex interaction, CFD analysis is probably the only efficient tool in order to assess specific design parameterization of a generic car shape. Building on the credibility of such instruments is one of the major goals of this paper. Also, with respect to a target sedan car configuration, examples of successful design strategies are presented. Based on the CFD results, possible strategies to be used in order to reduce viscous drag and global drag characteristics are proposed.

  20. Jazz improvisers’ shared understanding: A case study

    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.

  1. 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.

  2. Hybrid Risk Management Methodology: A Case Study

    2009-10-01

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

  3. Bayesian inference in physics: case studies

    International Nuclear Information System (INIS)

    This report describes the Bayesian approach to probability theory with emphasis on the application to the evaluation of experimental data. A brief summary of Bayesian principles is given, with a discussion of concepts, terminology and pitfalls. The step from Bayesian principles to data processing involves major numerical efforts. We address the presently employed procedures of numerical integration, which are mainly based on the Monte Carlo method. The case studies include examples from electron spectroscopies, plasma physics, ion beam analysis and mass spectrometry. Bayesian solutions to the ubiquitous problem of spectrum restoration are presented and advantages and limitations are discussed. Parameter estimation within the Bayesian framework is shown to allow for the incorporation of expert knowledge which in turn allows the treatment of under-determined problems which are inaccessible by the traditional maximum likelihood method. A unique and extremely valuable feature of Bayesian theory is the model comparison option. Bayesian model comparison rests on Ockham's razor which limits the complexity of a model to the amount necessary to explain the data without fitting noise. Finally we deal with the treatment of inconsistent data. They arise frequently in experimental work either from incorrect estimation of the errors associated with a measurement or alternatively from distortions of the measurement signal by some unrecognized spurious source. Bayesian data analysis sometimes meets with spectacular success. However, the approach cannot do wonders, but it does result in optimal robust inferences on the basis of all available and explicitly declared information

    Full Text Available Los tumores de parótida en pediatría son infrecuentes, pues constituyen aproximadamente el 0,5 % de todos los cánceres. Se presentan, generalmente, como un aumento de volumen local y asintomático, otras veces se acompañan de dolor y signos inflamatorios. Se realizó un estudio retrospectivo, longitud [...] inal y descriptivo, para determinar la frecuencia y formas de presentación de los tumores de parótida diagnosticados en pacientes con edades comprendidas de 0 a 18 años, que han sido ingresados en el servicio de oncocirugía del Hospital "William Soler", entre febrero del año 2001 y diciembre de 2010, teniendo en cuenta: sexo, las formas de presentación, respuesta al tratamiento, así como las variantes histológicas presentadas, con el objetivo de dar a conocer estas variantes de tumores de parótida en pediatría, que, a pesar de ser infrecuentes, cuando se presentan constituyen un grupo de alto riesgo. Se diagnosticaron 7 pacientes, de los cuales 3 fueron adenomas pleomorfos, un adenocarcinoma, un carcinoma mucoepidermoide de la glándula, un linfoma de Hodgkin parotídeo y un tumor mixto con células atípicas de la glándula. El inicio de todos fue la presencia de una masa parotídea, en 6 de los casos asintomáticos, y en un caso con dolor local. Se le realizó ultrasonido de la glándula y biopsia aspirativa con aguja fina a todos los pacientes. El sexo masculino predominó sobre el femenino en una proporción 5 a 2, la edad media de presentación fue 12,3 años. La cirugía es el arma terapéutica principal en la mayoría de los casos. Se recomienda el seguimiento estrecho de los pacientes por el alto índice de recurrencia local. Abstract in english 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.

    Quinolone antibacterials are veterinary drugs authorized for use in food animal production. The analysis of residual amounts of drugs in food from animal origin is important for quality control of products for consumers. For this purpose, Maximum Residue Limits (MRLs) have been set up by a European Union Council Regulation on Veterinary Drug Residues (No. 90/2377/EEC and subsequent), and 8 quinolones received MRLs at concentration levels depending on both the matrix and the animal species of interest. A method was developed for screening and confirming 10 quinolone residues (ciprofloxacin, danofloxacin, difloxacin, enrofloxacin, flumequine, marbofloxacin, nalidixic acid, norfloxacin, oxolinic acid, sarafloxacin) in a wide variety of matrixes of different animal species. It involves extraction of the residues from the biological tissues/fluids by acidic aqueous solution, centrifugation and filtration prior to injection on a C18 narrow-bore column, and detection through a 3-step-mode fluorescence detector. The method was validated during a 2-week study for a set of 8 species-matrixes (i.e., bovine raw milk, bovine muscle, porcine muscle, porcine kidney, porcine liver, fish flesh and skin, poultry muscle, whole egg). Residues were quantified down to 15 microg/kg with limits of detection and quantitation ranging from 4 to 11 and 13 to 36 microg/kg, respectively, which are sufficient compared to the wide range of MRLs set for these substances (from 30 microg/kg for danofloxacin in milk to 1900 microg/kg for difloxacin in poultry liver). The limit of performance of the method in terms of CCalpha and CCbeta, the critical concentrations stated in the Decision No. 2002/657/EC and the ISO Standard No. 11843, has been calculated for the authorized (MRL) substances but only estimated in the case of the nonauthorized (non-MRL) substances.

    Extraskeletal mesenchymal chondrosarcoma (EMC) is a rare soft-tissue tumor that most arises in young adults. Because of its rarity, few imaging studies have been reported to date. The purpose of this study was to elucidate the imaging features of this tumor. We conducted a multi-institutional study in cooperation with five referral cancer centers in Japan. Imaging findings of ten new EMC cases, including conventional radiography, computed tomography (CT), and magnetic resonance imaging (MRI), performed at each institute, were reviewed along with clinical features. Ten patients with EMC, who had been treated at each hospital from 1990 to 2001, participated in this study. Soft-tissue masses with well-demarcated, dense and granular calcification were most frequently observed on plain radiographs and CT scans. T2-weighted MR images most clearly depicted a two-component structure composed of calcified and uncalcified areas, and enhanced MRI showed inhomogeneous enhancement in both areas. Although the sensitivity and specificity of these findings are unknown, they might be characteristic and have diagnostic value for this rare tumor. (orig.)

  19. Antenatal stress: An Irish case study.

    LENUS (Irish Health Repository)

    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.

    MAUS (materials science autonomous experiments) is one out of a series of flight opportunities which the Space Program of West Germany offers to scientists from the disciplines of materials research and processing for performing materials science investigations under microgravity conditions. Up to now, ten MAUS experiments were flown which were dealing with the following scientific topics: decomposition of binary alloys with miscibility gap in the liquid state, interaction of a solidification front with dispersed particles, critical Marangoni number, investigation of the magnetic compound MnBi, shrinkage of gas bubbles in glass melts and slip casting. The ten future experiments are partly reflights with modification of the scientific objectives as well as new experiments in the fields of chemical reactions, heat transfer, glass technology and Ostwald ripening. Looking to ten flown payloads, the peculiarities of instrument technology in GAS-cans and its evolution is discussed with emphasis on structure, electronics and thermal design. A typical modern payload using 100 percent of the resource is presented.

    Five patients with radiation enterocolitis who were surgically treated are reported. The 5 patients had received irradiation therapy more than 5,000 rad for ginecologic malignancies. The period for the onset of symptoms of irradiation enteritis ranged from 8 months to 20 years however, 3 of them developed the symptoms within one year after irradiation therapy. Emergency surgery was carried out for bowel obstruction in 3 cases and for intestinal perforation in 2 cases. Bowel resection and primary anastomosis were performed by a one-step approach in 4 of them. Transient colostomy as preventive measure was added in 2 cases. It is very important for the one-step approach to resect the intestine at the healthy part far from the lesion of irradiation enteritis and to add a transient colostomy to prevent anastomolic insufficiency. Furthermore, suture material should be used less tissue reactive one. (author).

  2. Case studies: Soil mapping using multiple methods

    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.

  4. On court interpreters' visibility : A case study

    DEFF Research Database (Denmark)

    Dubslaff, Friedel; Martinsen, Bodil

    This paper is part of the initial stage of a larger empirical research project on court interpreting seen as a complex interaction between (at least) three co-participants. The empirical material consists of recordings of interpreted interrogations in court room settings and questionnaires filled in by the participants almost immediately after the interrogations and supplemented by interviews. The main objective of the project is to explore the interpreters' own perception of the quality of the service they render as well as the professional users´ and the other language users' perception of the quality of the service they receive. Ultimately, the findings will be used for training purposes. Future - and, for that matter, already practising - interpreters as well as the professional users of interpreters ought to take the reality of the interpreters' work in practice into account when assessing the quality of the service rendered/received. The paper presents a small-scale case study based on an interpreted witness interrogation. Recent research on the interpreter's role has shown that interpreters across all settings perceive themselves as "visible" (Angelelli 2003, 2004). This has led us to focus on the interpreter's interpersonal role and, in particular, on signs of the interpreter's visibility, i.e. active co-participation. At first sight, the interpreting assignment in question seems to be a short and simple routine task which would not require the interpreter to deviate from the traditional picture of the interpreter as an invisible language switcher. However, a closer look at the data shows that, even in a less complex constellation like the one analysed here, there is clear evidence of the interpreter's visibility. We shall identify various forms of visibility based on the discourse data, such as the interpreter's engagement in explicit co-construction of meaning. In addition, we shall include social factors which must be assumed to have a bearing on the interpreter's behaviour. Here we can, at least to some extent, draw upon the questionnaires and interviews mentioned above. Finally, we shall discuss the interpreter's visibility from a quality perspective.

    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. The context adaptability parameters, topology, metrics and physical properties.

    T cell rich B cell lymphoma (TCRBCL) is a recently described variant of diffuse non Hodgkin's lymphoma (NHL), the acronym of which has gained wide acceptance among hematopathologists in a relatively shorter period of time. The recognition of this entity requires immunohistochemical facilities especially on paraffin embedded tissues. TCRBCL is one of the many examples in the diagnostic anatomic pathology which emphasizes the need of immunocytochemistry and availability of this technique at least in referral laboratories. One of the differential diagnosis in this case includes lymphocyte predominance Hodgkin's disease (LPHD) which is the most favorable prognostic histologic subtype of Hodgkin's disease (HD) while TCRBCL is an aggressive B Cell NHL and should be treated as high grade large cell lymphoma. The other close differential includes peripheral T cell non-Hodgkin's lymphoma (PTCL). We reported sixteen (16) cases of TcRBCL diagnosed during a period of two and a half years (January 1995 to June 1997). HD and PTCL were the main differential diagnoses in most of these cases. The median age at diagnosis was 39 years and male to female ratio was equal. TCRBCL was nodal in location in 15 cases and a single case in extranodal site presenting as spinal tumor. The mean neoplastic B cell population was 12%, while that of reactive T cells was 82%. A significant polymorphous inflammatory cellular background was noted in 5 cases. Reed-Stenberg like cells were observed in 3 cases. Immunoglobulin light chain restriction studies were performed in fourteen cases and revealed lambda light chains in ten cases while in four cases kappa light chains were present. PMID:10420680

    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.

  19. PELE'S HAIR: case studies from Kilauea

    Science.gov (United States)

    Cannata, C. B.

    2010-12-01

    Pele’s hair are long, thin strands of basaltic volcanic glass formed when small drops of magma are spun or drawn out by the wind or streams of volcanic gas into long hair-like strands. Named for Pele, the Hawaiian goddess of fire, they are basically found in Hawaiian eruption deposits. Pele’s hair is deep yellow or gold and is commonly found downwind from active vents concentrated in hollows or other low energy ‘traps’. In literature the origin of these thin strands of glass have been linked to fountains from Hawaiian eruptions. Beside the high fountaining, Pele’s hair are actually found in other environments. In this work we investigated in detail the dimensions, surface textures and the nature of Pele’s hair, from four typical environment of formation at Hawaiian volcanoes: high fountaining, weak explosive activity, lava ocean entry and a lava skylight. Samples has been characterized in terms of textural and morphological features, in thin section and under the SEM. Pele’s hair consists of long strands of gold sideromelane, showing variable length, from an half mm to tens of mm, often without surface vesicles and sometimes including Pele’s tears inside or at the end. They are often found incomplete, since they are easily broken on landing or even during transport. Their surfaces are mostly rough, with ‘ploughs’ of different sizes and large cavities. Vesicles are visible in the cross sections of Pele’s hair. There are two mostly size population of bubbles: one elongated and central and parallel to the axis of elongation and the other one smaller, and rounded and dispersed across the cross section of the fibers. Pele’s hair often shows, in thin section, a single inner elongate vesicle in the middle of the fragment linked to bubble coalescence phenomena, along the entire length of the hair. Samples from the four volcanic environments show different features in terms of their shape, surface textures and micro-textures, pointing out that varying degrees of cooling, degassing and shear affect the texture and the processes of formation of Pele’s hair.

    2010-01-01

    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.

    Full Text Available Abstract Objectives To assess associations between subcutaneous neurofibromas (SC-NFs and internal neurofibromas in patients with neurofibromatosis type 1 (NF-1 and to determine whether the association between SC-NFs and peripheral neuropathy was ascribable to internal neurofibromas. 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

    2010-12-01

    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. Moreover, I argue, contra Beaver & Brady (2008, that only is not conventionally associated with focus, the focus effects arising instead pragmatically. But I do adopt aspects of their semantics for only, including the presupposition of a pre-order over the elements of its domain.ReferencesAbbott, B. 2000. ‘Presuppositions as non-assertions’.

  17. Measurement uncertainty and gauge capability of surface roughness measurements in the automotive industry: a case study

    International Nuclear Information System (INIS)

    The calculation methods of the capability of measurement processes in the automotive industry differ from each other. There are three main calculation methods: MSA, VDA 5 and the international standard, ISO 22514–7. During this research our aim was to compare the capability calculation methods in a case study. Two types of automotive parts (ten pieces of each) are chosen to examine the behaviour of the manufacturing process and to measure the required characteristics of the measurement process being evaluated. The measurement uncertainty of the measuring process is calculated according to the VDA 5 and ISO 22514–7, and MSA guidelines. In this study the conformance of a measurement process in an automotive manufacturing process is determined, and the similarities and the differences between the methods used are shown. (paper)

    2011-01-01

    Full Text Available Dirofilaria immitis is a parasite in a. pulmonalis in domestic and wild carnivora. Partial development and the transfer of this parasite among carnivora takes place through the mosquito, which makes possible the maintaining and spreading of this parasite among populations of susceptible animals. Heartworm disease, which is caused by Dirofilaria immitis, is most often manifested as changes in the respiratory and cardiovascular systems. This paper presents the case of heartworm disease in a dog. The therapy used to treat this disease in the dog was a combination of doxycycline and ivermectin. The blood test results indicated a rapid decrease in the number of microfilaria and lowering of the antigen level of the adult parasite. The conducted general and special clinical examinations of the respiratory and cardiovascular systems registered an improvement in the clinical condition of the patient.

  16. A case study of mental imagery deficit.

    Science.gov (United States)

    Farah, M J; Levine, D N; Calvanio, R

    1988-10-01

    We describe a patient with a deficit in imagery ability, following a left posterior cerebral artery infarction and possible anoxic episode. This deficit was inferred from the patient's performance on several tasks, including one in which normal adults are known to rely on imagery and two that tested imagery nonverbally, allowing us to examine the possibility of a language-imagery disconnection. In addition, we queried the patient on some cognitive capacities related to visual imagery: dreaming, geographical knowledge, and introspection regarding visual and auditory imagery. Hypotheses concerning the critical lesion site and underlying cognitive mechanism of image generation deficits are discussed in relation to this and other recent cases of impaired imagery ability with intact recognition ability, and the relevance of this deficit to the "imagery debate" is discussed.

  17. The shortcomings of computer-aided measurement of migration for the prediction of failure of three forms of acetabular fixation by survival analysis and migration study to ten years.

    Science.gov (United States)

    Scott, G; Nakagawa, S; Orhan, Z; Freeman, M

    2006-01-01

    We studied, to ten years, migration by vertical displacement and angular change using a digitizer and standard radiographs and survival of three methods of acetabular fixation in primary hip replacement. Two implants were uncemented metal-backed components, one version of which was hydroxyapatite-coated. Both types had 28 mm polyethylene inserts. The third type was a cemented all-polyethylene cup with a 28 mm internal diameter. All cups articulated with a Freeman neck-retaining stem. The purpose was to see if the early migration data predicted the long-term outcome and could be used to forecast implants that would fail for the purpose of pre-market assessment. No statistical differences were found between the groups in the parameters studied. At the threshold accuracies of our migration measurements (three millimetres and three degrees) at three years, we could not identify components that would subsequently fail. However, migration less than these threshold values and the absence of radiolucent lines were strongly associated with implant survival at ten years. Our system was insufficiently accurate for pre-market surveillance.; PMID:19219800

  18. U-opportunities: why is ten equal to ten?

    Energy Technology Data Exchange (ETDEWEB)

    Julia, B. [Laboratoire de Physique Theorique, ENS, 75 - Paris (France)

    2002-07-01

    It seems to me at this time that two recent developments may permit fast progress on our way to understand the symmetry structure of toroidally (compactified and) reduced M-theory. The first indication of a (possibly) thin spot in the wall that prevents us from deriving a priori the U-duality symmetries of these models is to be found in the analysis of the hyperbolic billiards that control the chaotic tune evolution of (quasi)homogeneous anisotropic String. Supergravity or Einstein cosmologies near a spacelike singularity. What happens is that U--duality symmetry controls chaos via negative constant curvature. On the other hand it was noticed in 1982 that (symmetrizable) 'hyperbolic' Kac-Moody algebras have maximal rank ten, exactly like superstring models and that two of these four rank ten algebras matched physical theories. My second reason for optimism actually predates also the previous breakthrough, it was the discovery in 1998 of surprising superalgebras extending U-dualities to all (p + 1)-forms (associated to p-branes). They have a super-nonlinear sigma model structure similar to the symmetric space structure associated to 0-forms and they obey a universal self-duality field equation. As the set of forms is doubled to implement electric-magnetic duality, they obey a set of first order equations. More remains to be discovered but the beauty and subtlety of the structure cannot be a random emergence from chaos. In fact we shall explain how a third maximal rank hyperbolic algebra BE{sub 10} controls heterotic cosmological chaos and how as predicted Einstein's General Relativity fits into the general picture.

  20. Case study: High capacity spiral concentrators

    Scientific Electronic Library Online (English)

    P., Ramsaywok; M.K.G., Vermaak; R., Viljoen.

    2010-11-01

    Full Text Available Spiral concentrators are compact, cost-effective and generally efficient gravity concentration separators for a wide range of applications (for example: coal, beach sands, iron ore, chromite and tantalite). Large mineral processing plants consist of thousands of spiral concentrators resulting in lar [...] ge plant footprints (capital intensive) and the adjustment of splitters is time consuming, impractical and is in many cases neglected-high capacity (HC) spiral concentrators aim to address these shortcomings. As a result Exxaro Namakwa Sands is currently investigating high capacity spiral technology for the spiral circuit upgrade at the primary concentrator plants (PCPs). This article summarizes the rougher spiral performance evaluation that was conducted on different types of spiral concentrators (the traditional MG4 spiral concentrator and the high capacity (HC) spiral concentrator) under different feed conditions. In addition, the effect of slimes on the spiral concentrator performance was also investigated. Slimes rheology was linked to the poor concentrator performance at the higher slimes concentrations. The test campaign shows a sacrifice in recovery under design-feed conditions can be expected when using high capacity spiral concentrators in the rougher stage when compared to traditional spiral technology currently in use. Both spiral concentrators show a detrimental impact of slimes on the performance, but the high capacity spiral concentrator is more sensitive to the higher slimes conditions.

  1. Tourette Syndrome neuropsychological profile: a study case

    Directory of Open Access Journals (Sweden)

    Eliana Gomes da Silva Almeida

    2014-04-01

    Full Text Available This article discusses findings resulting from the neuro-psychological assessment of an adolescent with Tourette Syndrome (TS, a rare neuro-developmental disorder characterized by the manifestation of physical and/or audible tics that emerge in childhood or early adolescence. Although we performed an extensive assessment of all cognitive functions, our reported findings focus on those functions that are described in prior research as relevant to the understanding of the cognitive profile of patients with this condition. The findings reported here are consistent with other reports and suggest that intellectual and long-term memory potentials are preserved, while noting deficiencies in executive functioning, reduced speed of mental and psycho-motor functions, and decreased recent memory capacity. Given the rarity of this diagnosis, our reporting of this case should contribute to the understanding of cognitive function in adolescents with TS. In addition, this article highlights and describes factors that affect the quality of neuropsychological assessment and facilitate accurate therapeutical diagnosis and referral for TS carriers.

  2. A case study in finite groups

    International Nuclear Information System (INIS)

    Recent investigations on the classification of rational conformal theories have suggested relations with finite groups. It is not known at present if this is more than a happy coincidence in simple cases or possibly some more profound link exploiting the analogy between fusion rules and decompositions of tensor products of group representations or even in a more abstract context q-deformations of Lie algebras for roots of unity. Although finite group theory is a very elaborate subject the authors review on a slightly non-trivial example some of its numerous aspects, in particular those related to rings of invariants. The hope was to grasp, if possible, some properties which stand a chance of being related to conformal theories. Subgroups of SU(2) were found to be related to the A-D-E classification of Wess-Zumino-Witten models based on the corresponding affine Lie algebra. Extending the investigations to SU(3) the authors have picked one of its classical subgroups as a candidate of interest

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

    Directory of Open Access Journals (Sweden)

    Liviu LICA

    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.

  12. Case studies of emergency management of screwworm.

    Science.gov (United States)

    Reichard, R

    1999-04-01

    Screwworm myiasis, caused by infestation of even minor wounds by the obligative parasitic larval stages of the New World screwworm (NWS) (Cochliomyia hominivorax) or Old World screwworm (OWS) (Chrysomya bezziana) flies, is a major cause of livestock morbidity and mortality in tropical and sub-tropical regions of the world. The two parasites occur in different hemispheres but are remarkably homologous. Animal health emergencies result from the invasion of new territories by the parasites or, in the case of NWS, reinfestation of areas from which the parasite had been eradicated after great effort and expense. The author reviews the biology of the parasites and the effects of screwworm, in addition to prevention of infestation upon the introduction of animals. Examples of three programmes or events are described. The first is the eradication of previously exotic NWS from an epizootic in Libya before the parasite spread to become enzootic in the Mediterranean Basin and eventually other areas of the Eastern Hemisphere. The second example reviews the serious consequences of the extension of the range of OWS into Iraq where conditions at the time were favourable for propagation and unfavourable for control. The third example describes the NWS programme strategy in North and Central America which, for forty years, has been to progressively achieve eradication and then protection of areas from north to south on that continent, employing the sterile insect technique (SIT). Outbreaks in areas where screwworm has already been eradicated divert costly programme resources and slow progress southwards, and are considered emergencies. Some problems encountered and the solutions found during the height of the eradication programme in Mexico are described. Although to date eradication of screwworms has only been accomplished with the application of SIT, this technique alone will not eradicate the pest. The author describes other elements which are required to control or eradicate screwworms. Programmes for this highly mobile parasite encompass large geographic areas and consequently require active and continuous international participation. PMID:10190211

    2012-07-01

    The research project 'KLIMAT' was 1.1.2009 to 31.8.2012. The main goal of this project was to develop a 'best practice' methodology for quantifying the carbon footprint of products with a focus on fruits, vegetables, dairy and meat products. The methodology was tested on six selected case products. One of these products was the carrot. The product was selected because it is a product with high sales volume, a large part of the production takes place in Norway, and it may be assumed to represent the root vegetables which are a very important group of vegetable products. Oestfold Research, in conjunction with BAMA and Gartnerhallen, collected the necessary data to conduct the study. Data came from a group of 13 producers with ties to Laagendalen that all products supplied to the Laagen Gulrot for processing and packing. The producers were voluntarily affiliated with an online reporting system for a variety of information, including information about resource use that were used in this study. Climate track of carrot packed in the cup was, according to the methodology that was developed 0.39 kg Co2-ekv/kg product delivered to the consumer, 0.44 kg Co2-ekv/kg consumed carrot. (Author)

    2012-01-01

    Purpose – This paper assesses the quality of the case study based research approach as documented in articles published during the past 13 years, based on a synthesis of indicators for the quality criteria truth-value, transferability, and traceability. Design/methodology/approach – Content analysis of 134 case study based articles published in six leading logistics and supply chain management (SCM) journals between 1998 and 2010 is used to assess and evaluate the quality of the case study based research approach as documented in these publications. Findings – This research provides an overview of the quality of the case study based research approach. Results show that the quality is generally low, supporting the ongoing, but empirically unsupported criticism on the quality of case study based research. The results also highlight which specific aspects authors and reviewers need to address to ensure high quality of the case study based research approach in published articles. Research limitations/implications – This study is limited to the analysis of published articles in six logistics and SCM journals. Further research should investigate different journals in logistics and other disciplines, and the relationship between the rigor of case study based research and its contribution to the field. Practical implications – The findings give guidance to authors and reviewers in developing articles with a high-quality case study based research approach and help reviewers and readers to evaluate the quality of the described approach. Originality/value – The paper verifies the validity of ongoing claims for more rigor in case study based research and identifies areas of improvement.

    Full Text Available Purpose: Traumatic rupture of the diaphragm is caused by blunt or penetrating trauma. Early diagnosis is difficult, and complications such as visceral herniation may arise. The aim of this study was to evaluate our diagnostic and therapeutic approaches for traumatic diaphragmatic ruptures in the last ten-year period.Patients and Methods: Thirty-five patients who were diagnosed with traumatic diaphragmatic ruptures in the last ten-year period were retrospectively reviewed. Of the patients, 24 were male and 11 female. The mean age of the patients was 30 yrs (range 14–66 yrs. The mechanism of injuries, associated injuries, diagnostic and surgical approaches, and the morbidity and mortality rate were evaluated.Results: Blunt injuries were common (71.4%. Chest x-ray, thorax CT, and video assisted thoracoscopic surgery were used for the diagnosis with a diagnostic rate of 22.8%, 22.7% and 58.8%, respectively. Interrupted and running techniques with nonabsorbable sutures were used to repair the diaphragma via thoracotomy in all patients. Pleural empyema was seen in two patients. The mortality rate was 2.9%.Conclusion: Video assisted thoracoscopy is a valuable diagnostic procedure in suspected traumatic diaphragmatic rupture with radio diagnostic procedures. Thoracotomy and primary repairing may be adequate, especially in the late period, for traumatic diaphragmatic ruptures.

  7. Exposure to magnetic fields of railway engine drivers: A case study in Italy

    International Nuclear Information System (INIS)

    A case study of exposure assessment of railway workers to static and extremely low frequency (ELF) magnetic fields is presented. A measurement campaign was conducted in aboard Italian main line trains. All measurements were performed on board during regular service (two engine drivers were simultaneously present), in all places potentially accessible to personnel, considering routes ranging from a few tens of kilometres to hundreds of kilometres. The measurement protocol was mostly based on broadband metres and personal metres were employed to assess individual exposure. Surveys on static and ELF magnetic fields were performed for seven different models of engine or electrified train. Traction motors were fed by alternating current (AC) current, except for two engines, where AC current fed only auxiliary services. The final result is that the average exposure to static magnetic field was a little higher than the background geomagnetic field; occasionally in few areas it could reach levels of the order of milli-tesla. The average exposure to ELF magnetic fields was in the order of 1-2 ?T, with higher levels (few micro-tesla) only for one engine; occasionally in hot spots, close to wiring or specific equipment, the field values could reach several tens of micro-tesla.

  13. Higher Education in Scandinavia : A Case Study

    DEFF Research Database (Denmark)

    Nielsen, JØrgen Lerche; Andreasen, Lars Birch

    2015-01-01

    The chapter examines how higher education in the Scandinavian countries of Denmark, Norway and Sweden are developing in relation to new contexts of globalization, national and international competition for students and research grants, economical efficiency and shortening of students’ length of studies. Two competing perspectives are at play; one seeing education as a public good and an important aspect of a welfare society, the other seeing education as an individual private investment. In Scandinavia higher education is generally free of tuition fees, and students are supported with study grants. During the 20th century, there has been a development towards universal access to education and diversification of educational institutions. The current tendency, however, is a process of centralization of higher education, fusions of existing institutions, focus on quality assurance, and discussions of limiting the growth of higher education.
