    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.

    This study describes ten cases of filicides committed by mothers who intentionally killed one or more of their children within 12 months after delivery. The data were collected from police and court records, forensic psychiatric records, autopsy reports, and other medical records. The mean age of the mothers was 28.5 years and of the victims 4 months. The symptoms of depression were clear: an irritable, severely depressed mood with crying spells, insomnia, fatigue, anxiety, preoccupation with worries about the baby's well-being and the mother's caring abilities, suicidal ideation, or even psychotic thoughts. Most mothers had had house calls from the public health nurse or psychologist. The mothers' conditions deteriorated rapidly, and the filicide was committed when the mother was left alone with the baby against her will. The babies were well taken care of, not neglected or abused. The majority of the mothers had felt that their own parents, especially their mothers, were very demanding, rejecting, and emotionally unsupportive. All the mothers had also had traumatic experiences in their childhood or in adulthood. PMID:18587626

    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.

    The aim of this study was to determine whether the cognitive impairment is associated with corpus callosum infarctions. Ten corpus callosum infarction patients were enrolled in this study. Their emotions, cognitive and language abilities, memory, comprehensive perception were assessed using the Chinese version of following measures: Mini Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), World Health Organization-University of California-Los Angeles Auditory Verbal Learning Test (WHO-UCLA AVLT), Wechsler Adult Intelligence Scale (WAIS) Digit Span subtest and so on. The same measurements were performed on healthy control participants as contrast for analysis. Infarction most frequently occurred in the body and/or splenium of the corpus callosum. The scores of the most cognitive tests in the corpus callosum infarction patients were significantly worse than those of the control participants (Pability, the patients showed significantly poorer performance at the overall level of MMSE than the controls did (Pabilities of execution, orientation, attention, calculation, delayed memory, language, and repetition capabilities in the patients with respect to the control (Pabilities, attention and calculating abilities.

  11. 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.

    Gianpaolo Maso

    Full Text Available BACKGROUND: Caesarean delivery (CD rates are commonly used as an indicator of quality in obstetric care and risk adjustment evaluation is recommended to assess inter-institutional variations. The aim of this study was to evaluate whether the Ten Group classification system (TGCS can be used in case-mix adjustment. METHODS: Standardized data on 15,255 deliveries from 11 different regional centers were prospectively collected. Crude Risk Ratios of CDs were calculated for each center. Two multiple logistic regression models were herein considered by using: Model 1- maternal (age, Body Mass Index, obstetric variables (gestational age, fetal presentation, single or multiple, previous scar, parity, neonatal birth weight and presence of risk factors; Model 2- TGCS either with or without maternal characteristics and presence of risk factors. Receiver Operating Characteristic (ROC curves of the multivariate logistic regression analyses were used to assess the diagnostic accuracy of each model. The null hypothesis that Areas under ROC Curve (AUC were not different from each other was verified with a Chi Square test and post hoc pairwise comparisons by using a Bonferroni correction. RESULTS: Crude evaluation of CD rates showed all centers had significantly higher Risk Ratios than the referent. Both multiple logistic regression models reduced these variations. However the two methods ranked institutions differently: model 1 and model 2 (adjusted for TGCS identified respectively nine and eight centers with significantly higher CD rates than the referent with slightly different AUCs (0.8758 and 0.8929 respectively. In the adjusted model for TGCS and maternal characteristics/presence of risk factors, three centers had CD rates similar to the referent with the best AUC (0.9024. CONCLUSIONS: The TGCS might be considered as a reliable variable to adjust CD rates. The addition of maternal characteristics and risk factors to TGCS substantially increase the

    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 : Stevens-Johnson syndrome (SJS and toxic epidermal necrolysis (TEN are rare immune-mediated severe cutaneous adverse reactions with incidence rate of 0.05 to 2 persons per million populations per year. Drugs are the most commonly implicated in 95% of cases. Aims : To audit the causative drugs, clinical outcome, and cost of management in SJS, TEN, and SJS-TEN overlap. Setting and Design: Tertiary care hospitals-based multicentric retrospective study (case series. Materials and Methods : Indoor case papers of SJS, TEN, and SJS-TEN overlap admitted between January 2006 and December 2009 in four tertiary care hospitals of Gujarat were scrutinized. Data were collected for demographic information, causative drugs, investigations, treatment given, duration of hospital stay, time interval between onset of symptoms and drug intake, clinical outcome, and complications. Data were analyzed to find out proportion of individual drugs responsible, major complications, and clinical outcome in SJS, TEN, and SJS-TEN overlap. Total cost of management was calculated by using cost of drugs, investigations, and consumables used during entire hospital stay. Statistical Analysis : One-way Analysis of Variance followed by Tukey-Kramer multiple comparison test was used for comparison of incubation period, duration of hospital stay, and cost of management. Results : Antimicrobials (50%, nonsteroidal anti-inflammatory drugs (22.41%, and antiseizure drugs (18.96% were the most commonly associated groups. Nevirapine (28.12% was the most common drug. Antiseizure drugs were more often associated with serious form of adverse reaction (TEN: 81.8% than other drugs. Duration of hospital stay (20.6 vs 9.7 days and cost of management (Rs 7 910/- vs Rs 2 460/- were significantly higher in TEN than SJS (P=0.020 and P<0.001, respectively.

    Objective: To gain further understanding of the antiphospholipid syndrome(APS). Methods: Analysing clinical and laboratory data on ten cases of APS. Results: Thrombocytopenia appeared in all cases. Venous thrombi of limbs appeared in five cases and neurological abnormalities in two cases. Renal impairments were found in three cases. One case manifested left renal venous thrombi and the other two cases thrombotic microangiopathy. Budd-Chiari syndrome was found in one case. One of the ten cases was catastrophic APS(CAPS) presented as acute diffuse swelling, cyanosis, pain, ischemia and necrosis in fingers and limbs, recurrent shock, ascites, hepatic and respiratory dysfunction. Anticoagulants and corticosteroids could be effective for dealing with APS. It was critical to treat catastrophic APS with anticoagulants or plasmapheresis as early as possible. Conclusions: APS shows variable manifestations for good prognosis, but catastrophic APS has fatal risk. The main treatment for APS is the use of anticoagulants and immunosuppressives.

    The aim of this study is to report the typical radiographic and MR imaging features of calcific myonecrosis, which help to distinguish this rare entity from other causes of a calcifying calf mass. Ten patients with a final diagnosis of calcific myonecrosis were referred to a specialist orthopaedic oncology service in a 5-year period with the presumptive diagnosis of malignancy based on recent clinical presentation and imaging findings. Radiographs were available for retrospective review in all ten cases and MR imaging in six. All patients presented with a slow-growing painless calf mass. All gave a history of major trauma to the lower leg many years before, but in only two cases did the referring clinician query whether trauma might be a contributory factor. Radiographs showed well-defined fusiform mineralised masses up to 25 cm in length arising within the calf. The calcification was consistently peripheral and plaque-like. Ossification was not present. MR imaging showed the anterior compartment to be involved in four cases and all compartments in two. T1- and T2-weighted images showed peripheral low signal intensity, more prominent on the T2-weighted images, because of the peripheral mineralization. The contents of the masses were variable on T1-weighted images depending on the differing amounts of blood breakdown products and were heterogeneous on T2-weighted images. The latter may be explained by a combination of the mineralisation and T2 shortening due to blood breakdown products. A gadolinium chelate, administered in two cases, failed to show any appreciable enhancement. Calcific myonecrosis has characteristic clinical, radiographic and MR features that should make the condition easy to recognise. Despite its rarity, it should be included in the differential diagnosis of focal mineralisation of the calf. (orig.)

    Full Text Available Abstract Primary lymphoma is an uncommon malignancy of the thyroid, comprising of 0.6 to 5 per cent of thyroid cancers in most series. Primary thyroid lymphomas (PTL occur most commonly in elderly women and are commonly of B- cell origin. These frequently present in clinical stage IE and IIE. We report here ten cases of PTL diagnosed over a period of about 7 years in our institute. Out of these ten cases, nine were diagnosed on fine needle aspiration cytology (FNAC and one case was misdiagnosed as lymphocytic thyroiditis. This case was diagnosed as Non- Hodgkin's lymphoma on surgical specimen. Five patients are disease free and doing well, while two died of disease and the other two were lost to follow-up. One patient is currently on chemotherapy. The salient clinical, biochemical, radiological features, FNA findings along with diagnostic difficulties are discussed.

    Full Text Available Background: Gestational trophoblastic disease (GTD defines a heterogenenous group ofinterrelated lesions that arise from the trophoblastic epithelium of the placenta. There are severalhistologically distinct types of GTD: hydatiform mole (complete or partial, persistant/invasivegestational trophoblastic neoplasia (GTN, choriocarcinoma and placenta site trophoblastictumors. The aim of this study was to determine the frequency and risk factors of GTD amongwomen admitted to Imam Khomeini Hospital in Ahvaz, Iran.Materials and Methods: This was a cross-sectional study conducted at Imam KhomeiniHospital in Ahvaz, Iran. All hospital records related to GTD (132 from 1996 until 2006 werereviewed. Demographic and histo-pathologic characteristics were extracted. Chi-square andFisher-exact tests were used to analyze all variables. P ≤ 0.05 was considered statisticallysignificant. SPSS, version 11 was used for statistical analysis.Results: The mean age of patients was 27.6 years. Most patients who presented with GTDwere of ages 18-35 years (71.3%. There was no relationship between age and hydatiformmole during the reproductive years. There were 28 (18.9% patients over the age 40, of which18 (15.90% of these had a complete hydatiform mole. Within this group, 9 (6.8% changedto a persistent mole. There was a significant relationship between age over 40 and completemole (p<0.02. The percentage of patients with blood groups A and O was the same (37.9%.There was a significant relationship between blood groups (O+ and A+ and complete mole(p<0.05.Conclusion: The most common age range for hydatiform mole was 18-35 years. Women overthe age of 40 had a more complete hydatiform mole, which is similar to the other countries.Age and blood group are two risk factors for hydatiform mole.

    2008-06-01

    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.

    Low back pain, caused by lumbar disc herniation, is prevalently treated with a conservative approach. In this study we valued the efficacy of High Intensity Laser Therapy (HILT), compared with accepted therapies such as TENS and NSAIDs. Laser therapy obtained similar results in the short term, but better clinical effect over time than TENS and NSAIDs. In conclusion high intensity laser therapy appears to be a interesting new treatment, worthy of further research.

    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.

    MRI of ten atypical MCT were reviewed correlating with pathology and to clarify why they did not include any hyperintense area on T1-weighted images (T1WI). Nine of the ten cases had a few sebaceous glands. Intra-tumoral chemical shift artifact was noted in four and the presence of the finding was diagnostic of the disease. Two with abundant thyroid tissue showed multilocular cyst whose fluid in some loculi indicated hyperintense on T1WI and hypointense on T2WI, which was similar to MR findings of struma ovarii. Four with complication such as hemorrhagic necrosis demonstrated inhomogeneous signals and they were hardly diagnosed correctly. (author)

    Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) induced by drugs are severe cutaneous adverse reactions, characterized by extensive detachment of epidermis and erosion of mucous membranes. In addition to the long term adopted Naranjo score to assess the causality of adverse drug reactions, ALDEN score derived from two large-scale case-control study also proved to be a useful assessment tool to evaluate the causality of drug-induced epidermal necrolysis recently. We described ALDEN score in detail and compared the assessment results of both tools applied through a real TEN case resulted in coadministrating acetaminophen and cefradine in this paper, and discussed the differentiation and suitability of two scores.%药物引起的史蒂文斯-约翰逊综合征(SJS)和中毒性表皮坏死松解症(TEN)是一种罕见严重的不良反应,其特征是广泛性的皮肤表皮剥离和黏膜侵犯。当评估可疑药物和SJS或TEN之间的因果关系时,除了Naranjo评分外,最近根据两个大型的病例对照研究结果所衍生的ALDEN评分也提供了新思路。本文结合1例同时服用对乙酰氨基酚和头孢拉定导致中毒性表皮坏死综合征的案例,应用ALDEN评分及Naranjo评分分析两种药物与ADR间的关联性,并讨论此两种评分方法的差异性及适宜性。

    2004-01-01

    The current study re-examines an exceptional case of a serial killer incarcerated since a decade ago. "Jacob" is the first serial killer apprehended in Israel. His known actions were committed during the eighties of the last century, and continued for eleven years. The victims were elderly individuals, including both his parents. Shortly after incarceration he became overtly schizophrenic and underwent five hospitalisations. The case is re-examined in view of changes, both in the perpetrator's diagnosis and criminal legislation. Was Jacob doomed to become a serial killer, or could his fate be avoided through early professional intervention? Were the killings presenting symptoms of a psychotic or pre-psychotic phase? Should he be eligible for a retrial? What would have been his position with the current law in view of the new 300A(a) clause ("Reduced Punishment") of the Israeli Criminal Code? Could he ever be released back to the community? These are some of the questions to be addressed.

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.

    2014-07-01

    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.

    Classification schemes proposed for vascular lesions are the subjects of significant controversy. Cutaneous epithelioid angiomatous nodule (CEAN) was described in 2004, but there is no agreement as to whether this is a distinct entity or a type of either epithelioid hemangioma or angiolymphoid hyperplasia with eosinophilia. We present a typical case of CEAN and discuss nine other cases from our institution. We then provide two opposing viewpoints concerning its classification. PMID:19379646

    2010-09-01

    Full Text Available Monodermal teratomas of the ovary can take the form of carcinoid tumors of which there are several types, mucinous carcinoid being the least common. Very few cases of primary mucinous carcinoid of the ovary have been reported in the literature and the behavior of these tumors over the long term is unclear. We describe a case of primary mucinous carcinoid of the ovary in a 39-year-old woman treated with unilateral salpingo-oophorectomy, where a metastasis occurred in the contralateral ovary ten years later. This case demonstrates that mucinous carcinoid of the ovary can metastasize even after a long interval, and careful follow-up of patients, particularly those treated conservatively, is appropriate.

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

    2014-05-01

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

    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.

    Galeazzi fractures represent approximately 3 to 6 percent of forearm fractures, whereas Monteggia fractures represent 1 to 2 percent. The combination of these injuries in the same extremity is an exceedingly rare occurrence. We report a case of ipsilateral combination of Galeazzi and Monteggia fractures in a ten-year-old patient. The patient was treated with closed reduction and internal fixation with Kirschner pins. The distal radioulnar and radiocapitellar joint relationships were restored and the fractures healed. The patient proceeded to obtain a satisfactory functional result three years later. Internal fixation is a safe method for such complex forearm fractures in older children and allows post-operative rehabilitation with the advantage of early mobilization.

    Full Text Available Ten Citrus (Linnaeus, 1753 species of North-East India have been karyo-morphologically analysed. All studied species had 2n=18 chromosomes without any evidence of numerical variation. All the chromosomes were found to be of metacentric and sub-metacentric in all the species; the morphology of the chromosomes showing size difference only. Symmetrical karyotype which does not have much difference in the ratio of longest to shortest chromosome in all the species was observed. Three species, C. grandis (Osbeck, 1757, C. reticulata (Blanco, 1837 and C. medica (Linnaeus, 1753 are identified as true basic species from asymmetry studies of karyotypes as they reflect on the primitive nature of their genomes. C. indica (Tanaka, 1937 occupies a special taxonomic position within the genus Citrus as a progenitor for other cultivated species

    Full Text Available Most of morphological studies of cities in Java tended to place the elements of traditional urban space such as Alun-alun, Mosque, Palace and Market as the main elements of city. Other elements such as the colonial urban space Resident Office, Fort, Church, Park and so on are often considered separately or placed as a complementary part. Through a morphological study  by exploring ten cities in Java, I found both elements of traditional and colonial urban space were set in a unique and various pattern. There are some findings indicating that the elements of colonial urban space significantly influence the city structure as well as those of the traditional ones. Therefore, understanding the urban space form in Java should include and put elements of both of traditional and colonial urban space as an integral part.

    Full Text Available The present work has focused on the assessment of the tolerance of ten accessions of carrot (L1, L2, L3, F4, E5, R7, R8, L10, G11 and S12 to salt stress, grown in the region of Sidi Bouzid. The tests were carried out under plastic greenhouse (during 5 months. The results obtained show that the salt stress reduced the parameters of growth and production. However, a difference in the response to salt stress was recorded between the accessions studied. A reduction in yield of up to 70 % with the concentration 3 g / l of NaCl, for different accessions studied is recorded. However, the accession L1 who has given the longer roots and dry matter yield and the largest root shows the most tolerant accessions unlike L10, G11 and S12 which are the most sensitive.

    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

    Intracranial hemorrhage (ICH) is a rare but major cause of death in immune thrombocytopenic purpura (ITP). The authors reviewed data of 1,840 patient with ITP, from 5 pediatric hematology centers in Egypt from 1997 to 2007, to study the incidence and risk factors of ICH. Ten cases of ICH were identified with a median age at presentation of 7.5 years; 4 patients had acute ITP, 2 persistent and 4 chronic. The platelet count was late referral to a specialized center. Our results suggest that treatment does not prevent ICH and that it can occur at any time during the course of the disease. Delayed referral can be considered a risk factor for unfavorable outcome of ICH, highlighting the importance of teaching sessions for patients and their parents to minimize subsequent morbidity and mortality of ICH in children with ITP.

    Full Text Available Hemicrania continua (HC is an uncommon primary headache first described as a syndrome in 1984. Being quite unusual, its clinical characterization still demands better description. The aim of this study is to present the main clinical characteristics of 10 patients with the diagnosis of HC seen in a tertiary center, critically discussing their main features. All subjects had strictly unilateral headache without side shift and absolute response to indomethacin. Seven patients (70% presented autonomic features during pain exacerbations. Four (40% had migrainous symptoms during the exacerbations and one presented partial relief with dihydroergotamine. One patient had pain excruciatingly severe during the exacerbations. Although the cardinal features of HC - continuous, unilateral, indomethacin responsive, remain strongly reliable, a refinement on the clinical characterization is needful and desired.Hemicrania continua (HC é uma cefaléia primária relativamente incomum primeiramente descrita enquanto sindrome em 1984. Por ser relativamente rara, sua apresentação clínica ainda carece de melhor descrição. O objetivo do presente estudo é apresentar e criticamente discutir as principais características clínicas de 10 pacientes com HC consecutivamente vistos em um centro de atendimento especializado. Todos os pacientes apresentavam cefaléia estritamente unilateral, sem alternância de lado e com absoluta resposta a indometacina. Sete pacientes (70% apresentavam sinais autonômicos durante a exacerbação da dor. Quatro (40% apresentavam sintomas migranosos durante as exacerbações e um apresentava alívio parcial com diidroergotamina. Um paciente apresentava exacerbações excruciantemente severas. Embora as principais características da HC - dor continua, unilateral, responsiva à indometacina - permaneçam extremamente associados à sindrome, um refinamento na caracterização clínica é necessário.

    Full Text Available Steven–Johnson Syndrome (SJS and Toxic Epidermal Necrolysis (TEN are severe adverse drug reactions, characterized by extensive epidermal detachment and erosions of mucous membrane. SJS/TEN is one of the most serious adverse reactions to Nevirapine (NVP treatment, commonly used in developing countries as first-line treatment of human immunodeficiency virus infection. In the last years TRAF3IP2 gene variants had been described as associated with susceptibility to several diseases such as psoriasis and psoriatic arthritis. We hypothesized that this gene, involved in immune response and in NF-κB activation, could also be implicated in the SJS/TEN susceptibility. We performed a full resequencing of TRAF3IP2 gene in a population of patients treated with NVP. Twenty-seven patients with NVP-induced SJS/TEN and 78 controls, all from Mozambique, were enrolled. We identified eight exonic and three intronic already described variants. The case/control association analysis highlighted an association between the rs76228616 SNP in exon 2 and the SJS/TEN susceptibility. In particular, the variant allele (C resulted significantly associated with a higher risk to develop SJS/TEN (p = 0.012 and OR = 3.65 (95% CI 1.33–10.01. A multivariate analysis by logistic regression confirmed its significant contribution (p = 0.027, OR = 4.39 (95% CI 1.19–16.23. In conclusion, our study suggests that a variant in TRAF3IP2 gene could be involved in susceptibility to SJS/TEN.

    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.

    The qualitative study in this article portrays the couple relationship among AIDS carriers, based on Sternberg's triangular love theory (involving domains of intimacy, passion and commitment). The central study hypothesis is that certain components of the Sternberg model will be more significant than others among the AIDS carrier population. The study was conducted on ten AIDS carriers aged 21-37 who had experienced a couple relationship. Six men and four women participated; most of them were in a romantic couple relationship of homosexual orientation.The interviewees answered a questionnaire that included the three domains-- intimacy, passion and commitment--in the personal interview technique. The interview focused on interviewee's attitude towards his/her relationship with a partner, as he/she understood it. The findings of the study focus on relevant content that was gathered from the interviews and these portray a limited view of couple patterns in the world of AIDS carriers. The study reveals two major findings regarding the carrier's desires: On the one hand, the carrier describes a powerful need for a stable, permanent relationship--from the diagnosis of AIDS and throughout the subsequent years. On the other hand, the carrier also expresses powerful sexual desires that are not necessarily limited to a permanent partner. Thus passion is the dominant among the three domains.The intimacy domain is mainly affected by disclosure of the disease and the joint coping that follows.The findings are discussed in the context of the romantic internalized model theory and Sternberg's triangular love theory.

Methods: Included in this retrospective/descriptive study were 30 children treated for liver tumors from 1375-1384 (ca. 1996-2005, at Children’s Hospital Medical Center, Tehran, Iran. We included the clinical, radiologic, and pathologic data of our patients, focusing on the frequency, etiology and outcome. Results: Patient ages ranged from three months to 12 years (median 3.8 years, with 18 males (60% and 12 females (40%. Of these, 17 patients had hepatoblastoma (55.66%, including 13 males and four females, with an age range of six months to five years. Four cases (13.33% had neuroblastoma. Hepatocellular carcinoma (HCC was found in three cases (10%, all of whom were carriers of hepatitis B. Two cases (6.66% were diagnosed with mesenchymal hamartoma, two cases (6.66% with hemangioendothelioma and two cases (6.66% with rhabdomyosarcoma and leiomyosarcoma of the biliary tract. Abdominal swelling and hepatomegaly were seen in all of patients. Jaundice was observed in two cases. Serum alpha-fetoprotein levels greater than 500 ng/ml were seen in 17 cases (56.66%. All patients were receiving specific treatment. The three-year survival rate was 65% for hepatoblastoma and 2% for HCC Conclusion: With the introduction of specific treatment, the survival rate for children with tumors of the liver has significantly increased. Further improvement can be achieved using diagnostic biopsy for hepatoblastoma, although it may result in complications, and preoperative chemotherapy followed by complete surgical excision (per International Society of Pediatric Oncology guidelines, yielding an outstanding survival rate of 80%.

    Full Text Available The aim of this paper is to investigate the interface between the formal and informal support provided to very old people against a background of increasing need for care and a decreasing number of potential informal caregivers. We used a sample of 323 community-dwelling octogenarians participating in the Swiss Interdisciplinary Longitudinal Study on the Oldest Old (SWILSOO (n=1441 interviews. Descriptive analyses and a multilevel model were used to test whether formal and informal services complemented or substituted one another. The study revealed that the amount of informal services increased significantly as the frequency of formal aid increased, indicating that the two networks were complementary in the majority of the cases. In 21.2% of the cases, the formal network partly substituted the informal network (as an adjustment and only in 6.4% of the cases did the informal support end after the formal support had increased (radical substitution. The concern that the introduction of formal services may curb the readiness of relatives and friends to provide care is thus unfounded.

    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.

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

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

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

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

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

    2015-01-01

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

  12. Study on trace elements of ten kinds of fish species at Beijing market by INAA

    International Nuclear Information System (INIS)

    Background: As the improvement of the living standard, the safety of food becomes more and more concerned currently. The fish is healthy food with more protein but less fat. Purpose: We bought ten species of fish from the market, which are often eaten by Chinese, and analyzed the trace elements of them by instrumental neutron activation analysis (INAA). So some detecting methods should be applied to give some suggestions for human. Methods: First of all, we choose six species of fresh water fish, including grass carp, weever, Wuchang Fish, tilapia, crucian, carp, and four species of frozen sea fish, including hairtail, yellow croaker, salmon, ling. All of them were collected from a supermarket in Beijing. Secondly, we remove the squama by Teflon coated scissor, wash the fish with de-ionized water and use ashless filter paper to absorb the water on the fish. Then we cut the squama-less part with titanium knife for about 10 g, put them into plastic bags separately and sealed, balance the net weight, use a tablet machine to press them into slice and freeze at -18℃ for 12 h. And then we put them into a vacuum desiccator to pump for 72 h, balance dry fish, calculate the ratio of moisture and triturate the sample into about 40 meshes in agate. Finally, we prepare three sub-samples about 300 mg with each packed by plastic bag for analysis. We put the samples, NIST-1632a and chemical standard material together, irradiate in micro neutron source reactor (MNSR) for 16 h, measure the radioactivity by Ge detector after cooling 5 d or 10 d, and calculate the contents of 16 elements by the ko-NAA and the relative method. Results: The contents of trace elements are different between fresh water fish and sea fish. The contents of As, Hg, Br: Na, Se in sea fish are apparently higher than fresh water fish, but the contents of Rb and Zn are contrary. Considering most fresh water fishes are feed, Zn was probably added in fodder. The content of As in weever is 2.4 μg·g-1, the

  13. A Further Study on the Ten-Penny Problem%十文钱问题再探

    Institute of Scientific and Technical Information of China (English)

    肖前国; 张凤华; 苟娜

    2012-01-01

    The ten-penny problem, an old Chinese reasoning illusion problem, was investigated by Li and Zhang for the first time ( 2008), which indicated that only 30% of the subjects succeeded in solving the problem, and resulted in a high error rate in the singleentry bookkeeping representation. However, the fact that most of the resolved-subjects also adopted the single-entry bookkeeping representation strategy was ignored in their studies. Therefore, it may not be appropriate to attribute the high error rate to the single-entry bookkeeping representation strategy. Based on the above analysis, three studies were conducted, and the chi-square test was used for most of the data analysis. In the first study, 198 undergraduate students were asked to solve the ten-penny problem and its heterogeneous issue. They were also required to write down on a booklet their explanations for their solutions. In the second experiment, we changed the presentation of the original problem and the modified problem by weakening the statements for studying whether this change improved their reasoning performance. In the third study, we provided two different cues. One was an external perceptual cue that was embodied by underlining some key state- ments, and the other internal cue required the subjects to apply critical thinking skills to read and resolve the original problem and the modified problem in the instruction. The results of three experiments indicated that ( 1 ) the subjects showed a error rate as high as on the heterogeneous issue of the ten-penny problem; (2) weakening the version of the ten-penny problem significantly improved the correct rate of reasoning; ( 3 ) presenting critical thinking clues also significantly improved the subjects' performance on the ten-penny problem. The results supported the hypotheses that the ten-penny problem was a reasoning illusion problem. The difficulty in solving this problem may be due to ① the surface character of the statement

    Isosurface extraction is an important and useful visualization method. Over the past ten years, the field has seen numerous isosurface techniques published leaving the user in a quandary about which one should be used. Some papers have published complexity analysis of the techniques yet empirical evidence comparing different methods is lacking. This case study presents a comparative study of several representative isosurface extraction algorithms. It reports and analyzes empirical measurements of execution times and memory behavior for each algorithm. The results show that asymptotically optimal techniques may not be the best choice when implemented on modern computer architectures.

    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.

    2016-07-01

    This study examined the development of ego-resiliency from late adolescence to emerging adulthood, using a 10-year cohort-sequential design. Participants were 335 Italian adolescents (173 females and 162 males), living, at the time of the study, in Genzano, a small city near to Rome. Latent growth curve analyses indicated that the developmental trajectory of ego-resiliency from 15 to 25 years is adequately described by a piecewise model that included separate growth profiles corresponding to different developmental stages. Essentially, ego-resiliency remained remarkably stable until the end of high school, and then encountered a phase of relative increase. Moreover, the trajectory of ego-resiliency from ages 15 to 19 was predicted by self-efficacy beliefs in managing negative emotions, and the trajectory from age 19 to 25 was predicted by experienced familial support and self-efficacy beliefs in expressing positive emotions at age 15. Experienced stressful life events also accounted for individuals' deviation from the typical ego-resiliency trajectory. PMID:27236209

    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

    2012-02-01

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

    2015-01-01

    Full Text Available 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.

TCI was administered in 1997 and mild depressive symptoms (modified Beck’s depression inventory, BDI were reported in 1997, 2001, and 2007. BDI-II was also administered in 2007. We found that high harm avoidance and low self-directedness related strongly to depressive symptoms. In addition, sensitive (NHR and fanatical people (ScT were especially vulnerable to depressive symptoms. high novelty seeking and reward dependence increased depressive symptoms when harm avoidance was high. These associations were very similar in cross-sectional and longitudinal analysis. Personality profiles help in understanding the complex associations between depressive symptoms and personality.

    This review summarizes a prospective, longitudinal 10-year study in Rochester, NY, with virtually every clinically diagnosed acute otitis media (AOM) confirmed by bacterial culture of middle ear fluid. Children experiencing 3 episodes within 6 months or 4 episodes in 12 months were considered stringently defined otitis prone (sOP). We found stringent diagnosis compared with clinical diagnosis reduced the frequency of children meeting the OP definition from 27% to 6% resulting in 14.8% and 2.4% receiving tympanostomy tubes, respectively. Significantly more often respiratory syncytial virus infection led to AOM in sOP than non-otitis-prone children that correlated with diminished total respiratory syncytial virus-specific serum IgG. sOP children produced low levels of antibody to Streptococcus pneumoniae and Haemophilus influenzae candidate vaccine protein antigens and to routine pediatric vaccines. sOP children generated significantly fewer memory B cells, functional and memory T cells to otopathogens following nasopharyngeal colonization and AOM than non-otitis-prone children and they had defects in antigen-presenting cells.

    In 1976, an accidental explosion in a plant near Seveso, Italy, caused the contamination of a populated area by 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). The area was subdivided into three zones (A, B, and R) having decreasing mean levels of TCDD soil contamination. This study examines the mortality between 1976 and 1986 among the subjects, aged 20-74 years, who were resident in the area since the accident (n = 556 in zone A, n = 3,920 in zone B, n = 26,227 in zone R). Subjects' exposure was classified by residence. A referent cohort of 167,391 subjects who lived in the immediate surroundings was concurrently examined. Vital status ascertainment was successful for over 99% of the subjects. Increased mortality from cardiovascular causes was found; incident-related stressors were considered more relevant to increased mortality than was TCDD exposure. Mortality from several cancers was elevated. The increases in biliary cancer (females), brain cancer, and lymphatic and hemopoietic neoplasms (particularly leukemia in males) did not appear to result from chance, confounding, or information/comparison bias. However, no definite patterns related to exposure classification were apparent. Merely suggestive increases in soft tissue tumors and melanoma were also noted. Liver and breast cancer mortality tended to be below expectations. Interpretation is hampered by the short observation period, small number of deaths from certain causes, and poor exposure definition. Further research is in progress.

  16. Vertebral Angiosarcoma. Case Study.

    2015-01-01

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

    Full Text Available With a growing number of species at risk of extinction, reintroductions have become an important component of several recovery schemes. In 2005, a recovery program including reintroduction and reinforcement efforts as well as monitoring activities was implemented in Québec for the endangered false hop sedge (Carex lupuliformis. Between 2005 and 2010, a total of 600 plants were reintroduced in different habitats (dry and wet on five distinct sites (swamps. Our objective was to determine which environmental variables (soil moisture, light availability, competition, aphid infestation influenced the survival and vigour (height, number of shoots, number of fruiting shoots of the transplanted individuals. We also compared the survival, growth and fecundity of transplanted and wild individuals. Discriminant analyses and ANOVAs indicated that exotic aphid infestation, excessive soil moisture and low light availability were the main causes of premature transplant death. Soil moisture (when not excessive, as shown by the survival analyses, light availability and competition volume positively influenced transplant vigour. Although only 4% of original transplants remain alive after a decade, at least one new population has established and total population has increased six-fold, when wild individuals and transplants still alive in 2015 are included in the calculations. Furthermore, at least 33% of transplants produced seeds at least once. Overall, transplants were less vigorous than wild individuals, but were found to live on average just as long, suggesting that the biological success of our reintroduction program is promising. Further studies of false hop sedge should include an examination of seed viability, to evaluate whether the small, newly-created populations experienced reduced germination.

    Full Text Available OBJECTIVE: Although surgical-site infection (SSI rates are advocated as a major evaluation criterion, the reproducibility of SSI diagnosis is unknown. We assessed agreement in diagnosing SSI among specialists involved in SSI surveillance in Europe. METHODS: Twelve case-vignettes based on suspected SSI were submitted to 100 infection-control physicians (ICPs and 86 surgeons in 10 European countries. Each participant scored eight randomly-assigned case-vignettes on a secure online relational database. The intra-class correlation coefficient (ICC was used to assess agreement for SSI diagnosis on a 7-point Likert scale and the kappa coefficient to assess agreement for SSI depth on a three-point scale. RESULTS: Intra-specialty agreement for SSI diagnosis ranged across countries and specialties from 0.00 (95%CI, 0.00-0.35 to 0.65 (0.45-0.82. Inter-specialty agreement varied from 0.04 (0.00-0.62 in to 0.55 (0.37-0.74 in Germany. For all countries pooled, intra-specialty agreement was poor for surgeons (0.24, 0.14-0.42 and good for ICPs (0.41, 0.28-0.61. Reading SSI definitions improved agreement among ICPs (0.57 but not surgeons (0.09. Intra-specialty agreement for SSI depth ranged across countries and specialties from 0.05 (0.00-0.10 to 0.50 (0.45-0.55 and was not improved by reading SSI definition. CONCLUSION: Among ICPs and surgeons evaluating case-vignettes of suspected SSI, considerable disagreement occurred regarding the diagnosis, with variations across specialties and countries.

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

    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

    Full Text Available The Norwegian Food Allergy Register was established at the Norwegian Institute of Public Health in 2000. 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.

    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.

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

    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.

    Based on the interpretation of composite imagery of band 4, 3, 2 of Landsat 5 in 2000 and 2009, analyzed, study area changes of the landscape pattern were analyzed. The landscape pattern evolution in the context of climate change was investigated combined with the meteorological data of 30 years to reveal the relationship between environment and climate change. Results showed that both forestland and grassland areas were increased over the past decade. However, the overall ecological environment of studied area degenerated reflecting in significant reduction of water and low wetland meadow as well as increased low salt meadow area. The temperatures of studied areas rise significantly under the background of global warming. The ecological environment became worse with uneven distribution of seasonal rainfall and persistent drought. Both agriculture and animal husbandry production were affected. Based on above analysis the following strategies were suggested to restore and improve the ecological environment, eventually realize the regional sustainable development in the context of climate change; strengthen ecological and environmental protection, limit or eliminate the interference factors of causing ecosystem degradation, make full use of the system self-healing capabilities.%利用2000年和2009年2个时期的Landsat 5的4,3,2(RGB)波段合成影像的解译结果,分析研究区近10年的景观格局变化,并结合气象数据,探讨景观格局在气候背景下的演变规律,揭示生态环境变化与气候变化的关系.结果表明:10年来研究区林地和草地面积有所增加,但区域整体生态环境还是呈退化趋势,表现为水域及低湿地草甸的大量减少和低地盐化草甸的增加;在全球气候变暖背景下,研究区气温上升趋势明显,加上降水量季节分布不均,持续的干旱使生态环境变得更差,农牧业生产受到极大影响.基于分析结果,指出在气候变化背景下,应加强生态环境

    Full Text Available BACKGROUND : Orthopaedic surgeons have long maintained that all children who have sustained a diaphyseal fracture of femur recover with c onservative treatment, given the excellent remodeling ability of immature bone in children. Angulations, shortenings and malrotations are not always corrected by conservative treatment. Of many surgical options, titanium elastic nailing has been the newer implant which is being used regularly. Although good results have been reported with elastic intramedullary nails, plate fixation continues to be a viable alternative in surgical treatment of femoral shaft fractures. However there are not many studies comp aring the efficiency of titanium elastic nailing and plating for femoral diaphyseal fractures in pediatric age group. AIM : The present study aims to compare the surgical management of diaphyseal fractures of femur in children with Dynamic Compression Plati ng versus Titanium Elastic Nailing. DESIGN : This is a prospective study . MATERIALS AND METHODS : This prospective study was conducted in a tertiary hospital. Patients who presented to the out - patient department and casualty of the hospital with femoral diap hyseal fractures during April 2012 to June 2014 were considered for the study.

    Rađa 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.

The primary goals of this study are to first examine the potential negative effects of perinatal environmental chemical exposures on birth outcomes, including congenital malformations and growth retardation; second, to evaluate the development of allergies, infectious diseases and neurodevelopmental disorders and perform longitudinal observations of the children's physical development to clarify the causal relationship between these outcomes and environmental chemicals; third, to identify individuals genetically susceptible to environmental chemicals; finally, to identify the additive effects of various environmental factors in our daily life, such as secondhand smoke exposure or low folate intake during early pregnancy. In this paper, we introduce our recent progress in the Hokkaido study with a cohort profile updated in 2013. For the last ten years, we followed pregnant women and their offspring, measuring various environmental chemicals, i.e., PCB, OH-PCB and dioxins, PFCs (Perfluorinated Compounds), Organochlorine pesticides, Phthalates, bisphenol A and mercury. We discovered that the concentration of toxic equivalents (TEQ) of dioxin and other specific congeners of PCDF or PCDD have effects on birth weight, infants' neurodevelopment and immune function. There were significant gender differences in these effects; our results suggest that male infants have more susceptibility to those chemical exposures than female infants. Interestingly, we found maternal genetic polymorphisms in AHR, CYP1A1 or GSTs that significantly modified the dioxin concentrations in maternal blood, suggesting different dioxin accumulations in the bodies of individuals with these genotypes, which would lead to different dioxin exposure levels. These genetic

  1. 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 (ρ = -0.49, and to a decrease in the rate of this deformation during the final half hour of each day (ρ = -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.

    Long-term epidemiological and laboratory studies were carried out in a kindred with familial pheochromocytoma associated with von Hippel-Lindau disease. Thirteen members were affected by the syndrome and the trait appears to be transmitted in an autosomal dominant fashion. Of 13 patients, 7 had pheochromocytoma alone. Of the remaining six patients, one had pheochromocytoma combined with von Hippel-Lindau disease, four had pheochromocytoma with retinal disease only, and a single patient had a retinal lesion without pheochromocytoma. In four patients, pheochromocytoma antedated the development of retinal lesions. Ten members also had mild hypercalcemia without accompanying elevations of PTH in the 4 patients in whom this was determined. In all, hypercalcemia was corrected with removal of tumors, and no patient had a return of hypercalcemia in the absence of recurrent increases in urinary catecholamines. The clinical presentations in 12 patients varied markedly, as did their urinary excretion rates of norepinephrine, epinephrine and their metabolites. However, an analysis of the data revealed significant correlations not previously described between the urinary excretion of free catecholamines (norepinephrine plus epinephrine), blood pressure, the free catecholamine content of the tumor and the age of the patient. Urinary excretion of free norepinephrine plus epinephrine appear to be decreased with advancing age (p less than 0.001). Both systolic and diastolic blood pressures and the age of the patient were inversely correlated (p less than 0.01). A significant inverse relationship between the tumor content of free catecholamines and the age of the patients was, although to a lesser degree, also present (p less than 0.05). As a whole, the size of the tumors and their norepinephrine content were not correlated. We present a concept that, in familial pheochromocytoma, the metabolism of catecholamines is altered by the process of aging, and that this change modifies the

  9. 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

  10. 18O/16O studies of fossil fissure fumaroles from the Valley of Ten Thousand Smokes, Alaska

    2001-06-01

    At three sample sites where there are good exposures of the upper 15 m of the 1912 ash-flow sheet in the Valley of Ten Thousand Smokes (VTTS), Alaska, 18O/16O studies indicate that fumarolic activity produced a very wide range of δ18O values (-0.1 to +12.6; n=32) in the groundmass adjacent to fossil fissure fumaroles. This contrasts sharply with the uniformity of δ18O in the groundmass away from fumarolic conduits (δ18O=+5.9 to +7.1; n=7) and in all of the feldspar phenocrysts (δ18O=+6.11 to +7.5 1 for 11 samples from this study and Hildreth 1987), independent of whether these were collected from fossil fumaroles or from unaltered tuff. Only one sample contained feldspars that were even slightly 18O-enriched relative to the others (cloudy plagioclase δ18O=+8.45). and this sample also contained the most 180-enriched groundmass of any of those analyzed (δ18O=+12.6). This preservation of primary magmatic δ18O values in the VTTS feldspar phenocrysts is clearly a consequence of the extremely short time span (i.e., 1912 to ≈1923) of vigorous, high-temperature, fumarolic activity in the 1912 ash-flow sheet. These 18O/l6O systematica are strikingly similar to those discovered in the 2.8-Ma intracaldera Chegem Tuff (Gazis et al. 1996) and in the fossil fumaroles in the outflow sheet of the 0.76 Ma Bishop Tuff (Holt and Taylor 1998), thus confirming that a similar type of fumarolic meteoric-hydro-thermal activity occurred above the zone of intense welding in all three of these ash-flow tuffs. This is particularly important, because it provides a direct linkage between the older tuffs and the actual observations at the VTTS of steam chemistry, water/rock interaction, circulation geometry, flow velocities, and fumarolic temperatures (up to 645°C). The 18O/l6O effects in the VTTS can all be explained in terms of a two-stage history: (a) an early, 10- to 15-year-long, high-temperature (τ;450°C), fumarolic 18O-depletion event (groundmass δ18O=-0.1 to +4.8); and (b) a

    Full Text Available Soybean (Glycine max L. Merril is widely grown in the mid hills as intercrop with maize or in paddy bunds, while it is gaining popularity as sole crop in terai and inner terai. Mean temperature at Khumaltar during soybean growing period was mostly fluctuating; but we observed an increasing trend in temperature. Amount of rainfall was not changed dramatically but number of rainy days was decreased during study period. Rainfall during germination time increase soil moisture which also increase germination and found higher early stand. Days from sowing to 50% flowering and 90% maturity were short in the case of higher minimum temperature and low rainfall. Among the genotypes, AGS-377, AGS-378, AGS-379 and Tarkari Bhattmas-1 were more sensitive. However, seed yield decreased in the case of higher temperatures and low rainfall. Cool night temperatures and high moisture increased disease incidence in soybean which, eventually reduced yield. In last three years, plant suffered from moisture stress during early vegetative stage and high moisture during late vegetative stage which reduced seed yield and seed weight. In conclusion, we found that genotypes like AGS- 360, Sathiya and Tarkari Bhatmas-1 are very sensitive to climatic variation.

    Pamela experiment has been designed as a cosmic ray observatory at 1 AU, dedicated to the precise and high statistics study of CR fluxes on a three decades energy range, form a few tens MeV up to several hundred GeV region. It is the last step of the 'Russian-Italian Mission' (RIM) program born in 1992 between several Italian and Russian institutes and with the participation of the Royal Institute of Technology of Stockholm (Sweden) and the Siegen University (German). Launched the 16 June 2006 from Baikonur cosmodrome on board of the Resurs-DK1 Russian satellite by a Soyuz rocket in an elliptical (350-610 km) quasi polar orbit (70° inclination) it was activated on 21 June 2006, afterword has been in a continuous data taking mode for ten years. The Pamela program pays particular attention to the study of particles (protons and electrons) and antiparticles (antiprotons and positrons) energy spectra. It also includes search for possible signals of dark matter annihilation, search for primordial antimatter (antihelium), search for new Matter in the Universe (Strangelets?), study of cosmic-ray propagation, solar physics and solar modulation, terrestrial magnetosphere. This program is made possible thanks to the outstanding performance of the instrument, the low energy threshold, the quasi-polar orbit, the 10 years duration of the observation. Protons and helium nuclei are the most abundant components of the cosmic radiation and the precise measurements of their fluxes allow understanding the acceleration and propagation of cosmic rays in the Galaxy. Their spectral shapes cannot be well described by a single power law: at 230-240 GV they exhibit an abrupt spectral hardening. They challenge the current paradigm of cosmic-ray acceleration in supernova remnants followed by diffusive propagation in the Galaxy. Of paramount importance is the discover of the anomalous increase of the positron flux at energies higher that 50 GeV (the so called 'Pamela anomaly'). The review of

    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.

    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

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

    Powers of Ten is a 1977 short documentary film written and directed by Charles Eames and his wife, Ray. The film depicts the relative scale of the Universe in factors of ten (see also logarithmic scale and order of magnitude). The film begins with an aerial image of a man reclining on a blanket; the view is that of one meter across. The viewpoint, accompanied by expository voiceover, then slowly zooms out to a view ten meters across ( or 101 m in standard form), revealing that the man is picnicking in a park with a female companion. The zoom-out continues, to a view of 100 meters (102 m), then 1 kilometer (103 m), and so on, increasing the perspective—the picnic is revealed to be taking place near Soldier Field on Chicago's waterfront—and continuing to zoom out to a field of view of 1024 meters, or the size of the observable universe. The camera then zooms back in to the picnic, and then to views of negative powers of ten—10-1 m (10 centimeters), and so forth, until we are viewing a carbon nucl...

    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

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

    Full Text Available 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.

    Women are twice as likely as men to suffer from depressive symptoms and disorder. Considerable research has focused on the physiological and psychosocial differences between men and women as sources of depression. An important target of study has been the periods of reproductive changes and events that occur at puberty, postpartum and menopause. A controversy has existed regarding the extent to which, if at all, the menopausal transition or postmenopause increases the risk for elevated depressive symptoms and/or disorders. SWAN provided an opportunity to address the issue with the largest, most representative and diverse cohort currently available for study. The current paper presents the findings from analyses conducted on data collected from the larger core SWAN study and an ancillary study on mental health begun in Pittsburgh in 1995. We found, as did four other recent longitudinal studies, that risk for high depressive symptoms and disorder is greater during and possibly after the menopausal transition. Multiple other factors contribute to risk for depression in our SWAN cohort. PMID:21961723

    In this research gas sealed Multi-Wire Proportional Counter (MWPC) including blades between anode wires and beta particles of (90)Sr with 196keV mean energy were considered. Ten different gases such as Noble gases mixtures with methane and several other pure gases were studied. In this type of detector, by using Garfield and Maxwell codes and for each of the gases, variation of different parameters such as first Townsend, electron attachment coefficients with variable electric field and their effects on pulse height or collected charge and in turn on Signal to Noise Ratio (SNR) were studied. Also the effect of anode voltage and its diameter and the pressure of gas on the pulse height were studied. Results show that Garfield and Maxwell codes can be used to study and improve the design of other gaseous detectors. PMID:27451113

    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.

    Full Text Available Medical personnel are at risk of musculoskeletal disorders but little is known whether the risk of musculoskeletal disorders were different among various medical professions. Therefore, this study compared the risk of musculoskeletal disorders among personnel of 10 different medical professions in Taiwan using a nationwide health claims database.Data from the 2000-2010 Taiwan National Health Insurance Research Database were used to identify personnel of 10 different medical professions. Diagnoses based on the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM were used to identify eight different musculoskeletal disorders that occurred after the license issuance date. Cox proportional hazards model was used to compare the risk of eight musculoskeletal disorders among the 10 different medical professions using dentists as the reference category.A total of 7,820 medical personnel were included in the analysis. Using dentists as the reference category, physical therapists showed a significantly higher risk of all eight musculoskeletal disorders (ranging from 1.59 [p = 0.032] in sprains and strains of other and unspecified parts of back to 2.93 [p < 0.001] in spondylosis and allied disorders.Compared with dentists, a profession that already known to suffer from high rates of work-related musculoskeletal disorders, physical therapists, registered nurses, and doctors of Chinese medicine showed an even higher risk of musculoskeletal disorders.

    The generation of electricity in nuclear power plants produces an increase in background radiation that could possibly have some impact on the organisms that live in that area. In order to identify and quantify any such possible effect, the natural populations of two sibling species, D. melanogaster and D. simulans, that live in the immediate vicinity of the first Mexican Nuclear Power Plant were analyzed for a period of 10 years. Collections of flies were made at two sites, one close to and one farther from the power plant, during the pre and operational stages of the reactor, and their egg-to-adult viability was analyzed. The data obtained indicate that in both sites, the egg-to-adult viability was generally higher in D. melanogaster than in D. simulans. Further, a relationship was found between egg-to-adult viability and the season of the year (warm-wet or cool-dry season). Some differences were found between the two sites. It may be concluded that there is no negative impact on the Drosophila populations studied. PMID:15106671

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.

  11. Recovery potential of a western lowland gorilla population following a major Ebola outbreak: results from a ten year study.

    Céline Genton

    Full Text Available Investigating the recovery capacity of wildlife populations following demographic crashes is of great interest to ecologists and conservationists. Opportunities to study these aspects are rare due to the difficulty of monitoring populations both before and after a demographic crash. Ebola outbreaks in central Africa have killed up to 95% of the individuals in affected western lowland gorilla (Gorilla gorilla gorilla populations. Assessing whether and how fast affected populations recover is essential for the conservation of this critically endangered taxon. The gorilla population visiting Lokoué forest clearing, Odzala-Kokoua National Park, Republic of the Congo, has been monitored before, two years after and six years after Ebola affected it in 2004. This allowed us to describe Ebola's short-term and long-term impacts on the structure of the population. The size of the population, which included around 380 gorillas before the Ebola outbreak, dropped to less than 40 individuals after the outbreak. It then remained stable for six years after the outbreak. However, the demographic structure of this small population has significantly changed. Although several solitary males have disappeared, the immigration of adult females, the formation of new breeding groups, and several birth events suggest that the population is showing potential to recover. During the outbreak, surviving adult and subadult females joined old solitary silverbacks. Those females were subsequently observed joining young silverbacks, forming new breeding groups where they later gave birth. Interestingly, some females were observed joining silverbacks that were unlikely to have sired their infant, but no infanticide was observed. The consequences of the Ebola outbreak on the population structure were different two years and six years after the outbreak. Therefore, our results could be used as demographic indicators to detect and date outbreaks that have happened in other, non

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

    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.

    2013-05-01

    The potential energy curves (PECs) of seventeen Ω states generated from the ten Λ-S states of the Si2(-) anion are studied in detail using an ab initio quantum chemical method for the first time. The PECs are calculated for internuclear separations from 0.10 to 1.20 nm by the complete active space self-consistent field method, which is followed by the internally contracted multireference configuration interaction approach with the Davidson modification. The spin-orbit coupling is accounted for by the Breit-Pauli Hamiltonian. Core-valence correlation and scalar relativistic corrections are considered. Core-valence correlation corrections are included using an aug-cc-pCVTZ basis set. Scalar relativistic correction calculations are made with the third-order Douglas-Kroll Hamiltonian approximation at the level of a cc-pV5Z basis set. Obvious effect of core-valence correlation corrections on the PECs is observed, in particular for the two lowest (2)Πu and (2)Σg(+) Λ-S states. All the PECs are extrapolated to the complete basis set limit. The lowest (2)Πu Λ-S state is found to be the ground state of Si2(-) anion. The convergence observations of present calculations are made and the convergent behavior is discussed with respect to the basis set and level of theory. The effects of core-electron correlations on the energy splitting are studied by the all-electron aug-cc-pCVTZ basis set. Using these PECs, the spectroscopic parameters of Λ-S and Ω states involved are determined. The vibrational manifolds are evaluated for each Λ-S and Ω state of non-rotation Si2(-) anion. It shows that the spectroscopic parameters and molecular constants of ten Λ-S and seventeen Ω states reported here can be expected to be reliable predicted ones. PMID:23501942

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

This model makes it possible to predict how the name distributions change and these predictions are shown to be borne out. In particular, the RGF model predicts that, for married women entering a collection of family books in a certain year, the occurrence of the most common family name "Kim" should be directly proportional the total number of married women with the same proportionality constant for all the years. This prediction is also borne out to high degree. We speculate that it reflects some inherent social stability in the Korean culture. In addition, we obtain an estimate of the total population of the Korean culture down to year 500 AD, based on the RGF model and find about ten thousand Kims.

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

    Full Text Available Brain metastasis from colorectal cancer is infrequent and carries a poor prognosis. Herein, we present a patient alive 10 years after the identification of a first brain metastasis from sigmoid colon cancer. A 39-year-old woman underwent sigmoidectomy for sigmoid colon cancer during an emergency operation for pelvic peritonitis. The pathological finding was moderately differentiated adenocarcinoma. Eleven months after the sigmoidectomy, a metastatic lesion was identified in the left ovary. Despite local radiotherapy followed by chemotherapy, the left ovarian lesion grew, so resection of the uterus and bilateral ovaries was performed. Adjuvant chemotherapy with tegafur-uracil (UFT/calcium folinate (leucovorin, LV was initiated. Seven months after resection of the ovarian lesion, brain metastases appeared in the bilateral frontal lobes and were treated with stereotactic Gamma Knife radiosurgery. Cervical and mediastinal lymph node metastases were also diagnosed, and irradiation of these lesions was performed. After radiotherapy, 10 courses of oxaliplatin and infused fluorouracil plus leucovorin (FOLFOX were administered. During FOLFOX administration, recurrent left frontal lobe brain metastasis was diagnosed and treated with stereotactic Gamma Knife radiosurgery. In this case, the brain metastases were well treated with stereotactic Gamma Knife radiosurgery, and the systemic disease arising from sigmoid colon cancer has been kept under control with chemotherapies, surgical resection, and radiotherapy.

    2014-03-01

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

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

    We report a case of massive associative visual agnosia. In the light of current theories of identification and semantic knowledge organization, a deficit involving both levels of structural description system and visual semantics must be assumed to explain the case. We suggest, in line with a previous case study, an alternative account in the framework of (non abstractive) episodic models of memory.

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

    The ambient air quality (AAQ) assessment was undertaken in Sukinda Valley, the chromite hub of India. The possible correlations of meteorological variables with different air quality parameters (PM10, PM2.5, SO2, NO2 and CO) were examined. Being the fourth most polluted area in the globe, Sukinda Valley has always been under attention of researchers, for hexavalent chromium contamination of water. The monitoring was carried out from December 2013 through May 2014 at six strategic locations in the residential and commercial areas around the mining cluster of Sukinda Valley considering the guidelines of Central Pollution Control Board (CPCB). In addition, meteorological parameters viz., temperature, relative humidity, wind speed, wind direction and rainfall, were also monitored. The air quality data were subjected to a general linear model (GLM) coupled with one-way analysis of variance (ANOVA) test for testing the significant difference in the concentration of various parameters among seasons and stations. Further, a two-tailed Pearson's correlation test helped in understanding the influence of meteorological parameters on dispersion of pollutants in the area. All the monitored air quality parameters varied significantly among the monitoring stations suggesting (i) the distance of sampling location to the mine site and other allied activities, (ii) landscape features and topography and (iii) meteorological parameters to be the forcing functions. The area was highly polluted with particulate matters, and in most of the cases, the PM level exceeded the National Ambient Air Quality Standards (NAAQS). The meteorological parameters seemed to play a major role in the dispersion of pollutants around the mine clusters. The role of wind direction, wind speed and temperature was apparent in dispersion of the particulate matters from their source of generation to the surrounding residential and commercial areas of the mine.

    2011-08-01

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

    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, 1.7μm). 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

    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.

  5. Ten Challenges for Decision Neuroscience

    Directory of Open Access Journals (Sweden)

    Scott A Huettel

    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.

Several features of the obesity epidemic in Africa mirror those in other emerging nations: it penetrates the richer nations and urban areas first with a strong urban- rural gradient; initially it affects the wealthy, but later there is a demographic switch as obesity becomes a condition more associated with poverty, and it shares many of the same drivers related to the increasing affordability of highly refined oils and carbohydrates, and a move away from subsistence farm work and towards sedentary lifestyles. Africa also has some characteristics of the obesity epidemic that stand out from other regions such as: (1) excepting some areas of the Pacific, Africa is probably the only region in which obesity (especially among women) is viewed culturally as a positive and desirable trait, leading to major gender differences in obesity rates in many countries; (2) most of Africa has very low rates of obesity in children, and to date African obesity is mostly an adult syndrome; (3) Africans seem genetically prone to higher rates of diabetes and hypertension in association with obesity than Caucasians, but seem to be relatively protected from dislipidemias; (4) the case-specific deaths and disabilities from diabetes and hypertension in Africa are very high due to the paucity of health services and the strain that the 'double burden' of disease places on health systems.

    2009-01-01

    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.

    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. Why is seed production so variable among individuals? A ten-year study with oaks reveals the importance of soil environment.

    Full Text Available Mast-seeding species exhibit not only a large inter-annual variability in seed production but also considerable variability among individuals within the same year. However, very little is known about the causes and consequences for population dynamics of this potentially large between-individual variability. Here, we quantified seed production over ten consecutive years in two Mediterranean oak species - the deciduous Quercus canariensis and the evergreen Q. suber - that coexist in forests of southern Spain. First, we calibrated likelihood models to identify which abiotic and biotic variables best explain the magnitude (hereafter seed productivity and temporal variation of seed production at the individual level (hereafter CVi, and infer whether reproductive effort results from the available soil resources for the plant or is primarily determined by selectively favoured strategies. Second, we explored the contribution of between-individual variability in seed production as a potential mechanism of satiation for predispersal seed predators. We found that Q. canariensis trees inhabiting moister and more fertile soils were more productive than those growing in more resource-limited sites. Regarding temporal variation, individuals of the two studied oak species inhabiting these resource-rich environments also exhibited larger values of CVi. Interestingly, we detected a satiating effect on granivorous insects at the tree level in Q. suber, which was evident in those years where between-individual variability in acorn production was higher. These findings suggest that individual seed production (both in terms of seed productivity and inter-annual variability is strongly dependent on soil resource heterogeneity (at least for one of the two studied oak species with potential repercussions for recruitment and population dynamics.

    2013-10-01

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

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

    We are interested in the motion of a classical charge coupled to the Maxwell self-field and subject to a uniform external magnetic field, B. This is a physically relevant, but difficult dynamical problem, to which contributions range over more than one hundred years. Specifically, we will study the Sommerfeld-Page approximation which assumes an extended charge distribution at small velocities. The memory equation is then linear and many details become available. We discuss how the friction equation arises in the limit of "small" B and contrast this result with the standard Taylor expansion resulting in a second order equation for the velocity of the charge.

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

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

    Full Text Available This India is the Fifth largest producer of Electricalenergy in the world. Despite such achievements the gapbetween demand and supply of electrical energy is increasingevery year and power sector is highly capital – intensive. Thusthe deficit in installed capacity was nearly 10000MWper year.So the gap between demand and supply is continuouslyincreasing day by day. An energy audit is a study of a plant orfacility to determine how and where energy is used and toidentify methods for energy savings. The opportunities lie inthe use of existing renewable energy technologies, greaterefforts at energy efficiency and the dissemination of thesetechnologies and options. This thesis provides an overview of ageneral energy conservation measures (ECMs that can becommonly recommended for NIT Hamirpur. It should be notedthat the Energy auidut presented in this paper does not pretendto be exhaustive nor comprehensive. It provides merely toindicate some of the options that energy auditor can considerwhen performing an analysis of this institute. Energyconservation and exploration of new energy avenues are thewell accepted solution to fulfil the demand in future. The totalcost of energy plays a vital role in determining the product costof a commodity. Therefore the identification of potential energysavings and implementation for a given institutional facility isunimportant to ensure its competitive advantage over otherinstitute. This paper work presents such energy saving methodsin a methodological approach, experienced during a detailedenergy audit of NIT Hamirpur.

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

    2015-01-01

    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...

  17. Towards More Case Study Research in Entrepreneurship

    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 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.

    Through data collection methods using a holistic approach that focuses on variables in a natural setting, qualitative research methods seek to understand participants' perceptions and interpretations. Common qualitative research methods include ethnography, phenomenology, grounded theory, and historic research. Another type of methodology that has a similar qualitative approach is case study research, which seeks to understand a phenomenon or case from multiple perspectives within a given real-world context.

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

    Full Text Available I teach an upper-level writing course, Genes, Race, Gender, and Society, designed for Life Science majors, in which I utilize a case study to expose students to ethical ways of thinking.  Students first work through the topical case study and then are challenged to rethink their responses through the lenses of ethics, taking into account different ethical frameworks.  Students then develop their own case study, integrating ethical components.  I want to expose my students to this way of thinking because I see technology being driven by the Jurassic Park phenomenon, "Your scientists were so preoccupied with whether or not they could, they didn't stop to think if they should." and want future physicians grounded in a sense of how their actions relate to the greater good.

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

    Full Text Available This paper discusses what the methods of conversation analysis (CA might have to offer the study of linguistic synonymy. It takes as a case study two items commonly held to be synonyms -'actually' and 'in fact'- and shows considerable differences between the two in their interactional implementation: they are implicated in the prosecution of differing courses of action. Such cases argue that it is analytically more profitable to consider what a lexical item does in the context of talk than what it means.

    Objective To retrospectively analyze the clinical management and follow-up of 13 recipients with survival of over ten years after cardiac transplantation. Methods Thirteen male recipients underwent orthotopic heart transplantation between August 1995 and June 2001 in our center and received standard immunosuppressive therapy protocols (8 cases) or induction therapy protocols (5 cases). Cyclosporine, azathioprine or mycophenolate mofetil, and prednisolone were applied as maintenance immunosuppressive regimens. Six recipients switched from azathioprine to mycophenolate mofetil when mycophenolate mofetil was available. Perioperative complications were prevented and treated. After operation, the recipients were followed up regularly to set up personnel long-term follow-up files. The incidence of acute rejection (AR) and (cardiac allograft vasculopathy (CAV) was monitored. Results The 13 survived recipients accounted for 48. 1 % of the total number in the corresponding period (13/27). All survivals recovered well and had a good quality of life. The recent (1 year) complications included acute allograft rejection (3 cases), infection (4 cases), renal insufficiency (3 cases), allograft right ventricular dysfunction (5 cases), post-transplant diabetes (2 cases) and liver dysfunction (5 cases). The long-term (1 year later) complications included acute allograft rejection (2 cases), CAV (2 cases), hypercholesterolemia (5 cases), hypertension (4 cases), hyperuricemia (10 cases) and chronic renal impairment (3 cases). One hepatitis B virus carrier died of liver cancer 13 years after transplantation. Conclusion The long-term survival of cardiac allograft recipients is closely associated with psychological state, financial condition, compliance and follow-up medical system, while the sociological and environmental factors may play important roles.%目的 总结单中心13例心脏移植后存活超过10年受者的治疗及随访情况.方法 13例受者在1995年8月至2001年6

    2011-08-01

    Collagenous ileitis (CI), characterized by subepithelial collagen deposition in the terminal ileum, is an uncommon condition. The few cases reported to date have been associated with collagenous colitis (CC) or lymphocytic colitis. Thirteen cases of CI retrieved over a 9-year period were retrospectively studied. There were 7 female and 6 male patients, with an age range of 39 to 72 years (mean, 64 y). Two groups were identified: (1) CI associated with collagenous or lymphocytic disease elsewhere in the gastrointestinal tract and (2) CI as an isolated process. Diarrhea was the presenting symptom in 11 cases. Most patients had no regular medication use. Subepithelial collagen thickness ranged from 15 to 100 μm (mean, 32 μm) and involved 5% to 80% of the subepithelial region of the submitted biopsies. Six cases had >25 intraepithelial lymphocytes (IELs)/100 epithelial cells, and villous blunting was observed in 11 cases. Chronic inflammation of the lamina propria was present in 9 cases, and focal neutrophil infiltration was identified in 3 cases. In biopsies taken from other sites, 7 of 13 colonic biopsies showed CC, 4 of 9 gastric biopsies showed collagenous gastritis, and 2 of 10 duodenal biopsies were abnormal with collagenous sprue (n=1) and partial villous atrophy and increased IELs (n=1) (both celiac disease related). Resolution of the subepithelial collagen deposition was found in the 1 case in which follow-up of terminal ileal biopsies were taken. There was partial or complete resolution of symptoms in 6 of 9 patients for whom follow-up information was available. PMID:21716082

    Meningitis and/or encephalitis can pose a serious public health problem especially during outbreaks. A rapid and accurate diagnosis is important for effective earlier treatment. This study aimed to identify the possible microbial causes of meningitis and/or encephalitis cases. CSF and serum samples were collected from 322 patients who had signs and symptoms suggestive of meningitis and/or encephalitis. Out of 250 cases with confirmed clinical diagnosis, 83 (33.2%) were definitely diagnosed as bacterial meningitis and/or encephalitis cases (by using CSF culture, biochemical tests, latex agglutination test, and CSF stain), 17 (6.8%) were definitely diagnosed as having viral causes ( by viral isolation on tissue culture, PCR and ELISA), and one (0.4%) was diagnosed as fungal meningitis case (by India ink stain, culture, and biochemical tests). Also, there was one encephalitis case with positive serum ELISA IgM antibodies against Sandfly scilian virus. N. meningitidis, S. pneumonia and M. tuberculosis were the most frequently detected bacterial agents, while Enteroviruses, herpes simplex viruses and varicella zoster viruses were the most common viral agents encountered. Further studies are needed to assess the role of different microbial agents in CNS infections and their effective methods of diagnosis.

METHODS Ten cases of ACL reconstruction operated upon with allografts assisted with arthroscopic technique were followed-up for 5 to 11 mo, mean 8 mo. RESULTS All patients had a quite satisfactory result with relief of symptoms and restoration of knee stability, immunologic rejective reaction was minimal, even invisible, but some grafts were gradually becoming a little laxity, particularly when 6 months postoperation, whereas it has not affected the primary results. All of them have gone back to their preinjury job. CONCLUSION Allograft is one of acceptable alternatives of reconstruction of torn ACL, but the long-term results still needs a further observation.

  17. Recurrent perinatal loss: a case study.

    Kavanaugh, K; Robertson, P A

    1999-01-01

    To date, investigators have not demonstrated a clear relationship between a parent's history of prior perinatal losses and intensity of grief response following a subsequent perinatal loss. Examining this relationship for low-income, African-American parents is important because they are a vulnerable population due to the high incidence of perinatal mortality in Blacks and their other life stressors that can impact on grief response and caring needs. The purpose of this case study was to examine the impact of recurrent perinatal loss on a low-income African-American parent. The research design for this study was case report, using interview data collected from a mother who had recently experienced her fourth perinatal loss, which occurred at twenty-five weeks of gestation. Transcripts from two open-ended interviews were analyzed. The theoretical framework used to guide analysis of this case study was Lazarus and Folkman's stress and coping theory. Results demonstrated that the prior perinatal losses did not appear as critical components of the way the mother responded to her most recent loss. Instead, perception of the care she received from healthcare providers and how that care related to her experiences with her one living child who was born at the same gestational age was an important determinant in how she responded to her loss. The results of this case study demonstrate the importance assessing a person's perception of their experience and those factors which contribute to the way they respond.

    2005-04-01

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

    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.

    AIM: Dieulafoy's lesion (DL) accounts for 1-5.8% of cases of acute upper gastrointestinal bleeding (GIB). Its mortality is high, approaching 20%, despite recent advances in endoscopic therapy. We aimed to report our experience in the treatment of DL.METHODS: A retrospective case study of all patients with DL between January 1993 and January 2003 was done. Characteristics, treatment methods, success rates and 30-d mortality of the patients were analyzed. RESULTS: Thirty-six patients were noted to have DL in the study period. Thirty-three records were available for assessment in which 35 DL were identified. The median age of the patients was 67 years with male to female ratio of 5.6:1. Significant comorbidities existed in 69% of the patients. Eighty-nine percent of the DL was found at first endoscopy, three DL at laparotomy. Significant coexistent endoscopic findings existed in 23%. Hemostasis was achieved in 88% by using adrenaline injection, or in combination with heater probe application at first endoscopy. Four cases had re-bleeding, all were successfully treated endoscopically. The 30-d mortality rate was 23%.CONCLUSION: Successful endoscopic hemostasis could be achieved in 100% of cases of DL. The overall mortality may still remain high, mainly due to the comorbidities and age of these patients.

  9. A Comparative Study of SSR Diversity in Chinese Major Rice Varieties Planted in 1950s and in the Recent Ten Years (1995-2004)

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Forty pairs of SSR markers were used to compare the genetic diversity changes in 151 Chinese major rice varieties planted in 1950s and in the recent ten years. Of 40 SSR loci, 39 were found to be polymorphic while one locus(RM479) monomorphic. A total of 213 alleles were identified from the 39 polymorphic loci. The average number of alleles per locus (Na) was of 5.5, ranging from 2 to 11. Nei's gene diversity index (He) varied drastically among loci from 0.309 at RM174to 0.869 at RM418, with an average value of 0.649. There existed significant difference in SSR allelic diversity between indica and japonica subspecies, and indica had more variation than japonica both in Na and He. By comparison with the genetic changes in Na and He, it was revealed that the varieties planted in 1950s had more alleles and higher He than those in the recent ten years both for indica and japonica rices. The difference between two subspecies for Na was significant in a tendency over.time (indica: z = 2.677, P = 0.007; japonica: z = 3.441, P = 0.001), but not significant for He (indica: z = 1.471,P = 0.141; japonica: z = 1.932, P = 0.053). Analysis of molecular variance (AMOVA) indicated that there existed significant difference (P < 0.05) in genetic variation between the two periods, of which more genetic variation was contributed by indica(Fst = 0.050) and japonica (Fst = 0.082) subsets. Using locus-by-locus AMOVA procedure, significant genetic differentiations were observed in 13 loci (RM21, RM128, RM147, RM169, RM190, RM221, RM231, RM251, RM253, RM317, RM341,RM418, and RM478) for indica varieties and 11 loci (RM101, RM135, RM152, RM159, RM169, RM190, RM251, RM253,RM311, RM418, and RM478) for japonica ones between the two periods. It was found some alleles had been lost in current major rice varieties as comparing with those in 1950s. Therefore, it should be necessary to exploit more alien elite genetic resources for extension of genetic background in current rice breeding program.

    2008-11-01

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

    Takao, Masaki; Hirose, Nobuyoshi; Arai, Yasumichi; Mihara, Ban; Mimura, Masaru

    2016-01-01

    Supercentenarians (aged 110 years old or more) are extremely rare in the world population (the number of living supercentenarians is estimated as 47 in the world), and details about their neuropathological information are limited. Based on previous studies, centenarians (aged 100-109 years old) exhibit several types of neuropathological changes, such as Alzheimer's disease and Lewy body disease pathology, primary age-related tauopathy, TDP-43 pathology, and hippocampal sclerosis. In the present study, we provide results from neuropathological analyses of four supercentenarian autopsy cases using conventional and immunohistochemical analysis for neurodegenerative disorders. In particular, we focused on the pathology of Alzheimer's disease and Lewy body disease, as well as the status of hippocampal sclerosis, TDP-43 pathology, aging-related tau astrogliopathy, and cerebrovascular diseases. Three cases were characterized as an "intermediate" level of Alzheimer's disease changes (NIA-AA guideline) and one was characterized as primary age-related tauopathy. TDP-43 deposits were present in the hippocampus in two cases. Neither Lewy body pathology nor hippocampal sclerosis was observed. Aging-related tau astrogliopathy was consistently observed, particularly in the basal forebrain. Small vessel diseases were also present, but they were relatively mild for cerebral amyloid-beta angiopathy and arteriolosclerosis. Although our study involved a small number of cases, the results provide a better understanding about human longevity. Neuropathological alterations associated with aging were mild to moderate in the supercentenarian brain, suggesting that these individuals might have some neuroprotective factors against aging. Future prospective studies and extensive molecular analyses are needed to determine the mechanisms of human longevity. PMID:27590044

    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.

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

    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.

    Full Text Available Ensuring the measurement effectiveness of Cost of Quality (COQ implementations presents steadily a practical managerial problem. Even though there are many approaches to measurement COQ optimal methods for this purpose in real conditions often depend on confrontation and evaluation of different calculation models. The paper based on a case study describes a procedure for comparison between so called controllable costs and incurred cost of poor quality. Presented study confirms assumption of a propitious influence of preventive costs on an overall COQ and a change of structure of separate cost of quality items.

    Background Breast cancer is the leading cause of cancer death in women worldwide. Nevertheless, it is unknown whether higher mortality after breast cancer contributes to the life-expectancy gap of 15 years in women with severe mental illness (SMI). Methods We estimated all-cause mortality rate ratios (MRRs) of women with SMI, women with breast cancer and women with both disorders compared to women with neither disorder using data from nationwide registers in Denmark for 1980–2012. Results The cohort included 2.7 million women, hereof 31,421 women with SMI (12,852 deaths), 104,342 with breast cancer (52,732 deaths), and 1,106 with SMI and breast cancer (656 deaths). Compared to women with neither disorder, the mortality was 118% higher for women with SMI (MRR: 2.18, 95% confidence interval (CI): 2.14–2.22), 144% higher for women with breast cancer (MRR: 2.44, 95% CI: 2.42–2.47) and 327% higher for women with SMI and breast cancer (MRR: 4.27, 95% CI: 3.98–4.57). Among women with both disorders, 15% of deaths could be attributed to interaction. In a sub-cohort of women with breast cancer, the ten-year all-cause-mortality was 59% higher after taking tumor stage into account (MRR: 1.59, 95% CI: 1.47–1.72) for women with versus without SMI. Conclusions The mortality among women with SMI and breast cancer was markedly increased. More information is needed to determine which factors might explain this excess mortality, such as differences between women with and without SMI in access to diagnostics, provision of care for breast cancer or physical comorbidity, health-seeking-behavior, and adherence to treatment.

    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.

    This report presents a number of case studies using the computer software package FORECAST MASTER (FM). The series studied and forecast are, aggregate monthly California Electricity Sales, system energy demand data from Ontario Hydro, peak demand data for the residential and commercial customers of Georgia Power Company, Massachusetts Electric commercial sales, Narragansett Electric commercial sales, average and peak demand using Georgia Power Company data. A variety of methods have been studied by each of the contributing authors; trend line fitting, exponential smoothing, Box-Jenkins univariate forecasting, vector autoregression, state space modeling, dynamic econometric models including time-varying parameters and general order serial correlation corrections. Thus both the data sets and the modeling/forecasting methodologies are varied. A number of conclusions emerge from these case studies: FM provides a powerful set of tools to aid a utility forecaster, a great deal of caution should be exercised in pre-processing the data; it can have unintended side effects, diagnostic tests are very useful in econometric models, the Akaike Information Criterion is a useful measure for selecting the best state space model, and state space and econometric approaches both need equal amounts of care in model analysis and presentation.

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

    This analysis presents a case study in California for a large scale, standalone wind electrolysis site. This is a techno-economic analysis of the 40,000 kg/day renewable production of hydrogen and subsequent delivery by truck to a fueling station in the Los Angeles area. This quantity of hydrogen represents about 1% vehicle market penetration for a city such as Los Angeles (assuming 0.62 kg/day/vehicle and 0.69 vehicles/person) [8]. A wind site near the Mojave Desert was selected for proximity to the LA area where hydrogen refueling stations are already built.

    Full Text Available Currently, in information technology domain and implicit in databases domain can be noticed two apparently contradictory approaches: centralization and distribution respectively. Although both aim to produce some benefits, it is a known fact that for any advantage a price must be paid. In addition, in this paper we have presented a case study, e-learning portal performance optimization by using distributed databases technology. In the stage of development in which institutions have branches distributed over a wide geographic area, distributed database systems become more appropriate to use, because they offer a higher degree of flexibility and adaptability then centralized ones.

  11. Case studies in Bayesian microbial risk assessments

    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

  15. 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.

    We conducted a one-year prospective study involving a prehospital Emergency Medical Service in the Netherlands to investigate the incidence of failed or difficult prehospital endotracheal intubation. During the study period the paramedics were asked to fill in a registration questionnaire after every endotracheal intubation. Of the 26,271 patient contacts, 256 endotracheal intubations were performed by paramedics in one year. Endotracheal intubation failed in 12 patients (4.8%). In 12.0% of 249 patients, a Cormack and Lehane grade III laryngoscopy was reported and a grade IV laryngoscopy was reported in 10.4%. The average number of endotracheal intubations per paramedic in one year was 4.2 and varied from zero to a maximum of 12. The median time between arrival on the scene and a positive capnograph was 7 min.38 s in the case of a Cormack and Lehane grade I laryngoscopy and 14 min.58 s in the case of a Cormack and Lehane grade 4 laryngoscopy. The incidence of endotracheal intubations performed by Dutch paramedics in one year was low, but endotracheal intubation was successful in 95.2%, which is comparable with findings in international literature. Early capnography should be used consistently in prehospital airway management. PMID:21612142

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

    The scheduling in job shop is important for efficient utilization of machines in the manufacturing industry. There are number of algorithms available for scheduling of jobs which depend on machines tools, indirect consumables and jobs which are to be processed. In this paper a case study is presented for scheduling of jobs when parts are treated on available machines. Through time and motion study setup time and operation time are measured as total processing time for variety of products having different manufacturing processes. Based on due dates different level of priority are assigned to the jobs and the jobs are scheduled on the basis of priority. In view of the measured processing time, the times for processing of some new jobs are estimated and for efficient utilization of the machines available an algorithm is proposed and validated.

    1998-01-01

    There have been numerous reports in the literature on the descriptive similarities between a severe nightmare and an acute psychotic episode. Nightmares may be a prelude to psychotic decompensation, and it has been suggested that frequent lifelong nightmares may even be diagnostic of an underlying vulnerability to psychosis. In this report, we present a case study of a 40-year old female experiencing chronic paranoid schizophrenia, whose two witnessed psychotic relapses in the hospital were immediately preceded by intense and vivid nightmare attacks. Significantly, the content of these nocturnal dreams was thematically consistent with her waking hallucinations, suggesting a direct continuity between these experiences. We propose that further systematic study of the dreams and nightmares of individuals diagnosed with schizophrenia may be particularly useful in understanding their phenomenological experience.

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

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

  3. Ten questions about systems biology

    2011-01-01

    In this paper we raise 'ten questions' broadly related to 'omics', the term systems biology, and why the new biology has failed to deliver major therapeutic advances for many common diseases, especially diabetes and cardiovascular disease. We argue that a fundamentally narrow and reductionist...... perspective about the contribution of genes and genetic variants to disease is a key reason 'omics' has failed to deliver the anticipated breakthroughs. We then point out the critical utility of key concepts from physiology like homeostasis, regulated systems and redundancy as major intellectual tools...... to understand how whole animals adapt to the real world. We argue that a lack of fluency in these concepts is a major stumbling block for what has been narrowly defined as 'systems biology' by some of its leading advocates. We also point out that it is a failure of regulation at multiple levels that causes many...

    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.

A batch of 10 superconducting decapole magnets for the LHC has just arrived at CERN from India. These will be used to correct for slight imperfections in the dipole magnets that will steer proton beams around CERN's new accelerator. All magnets have slight imperfections in the fields they produce, and in the LHC dipoles these will be corrected for using sextupoles and decapoles. The sextupoles were the first LHC magnets to be given the production green-light following successful tests of pre-series magnets last year (Bulletin 21/2000, 22 May 2000). Now it is the turn of pre-series decapoles to go on trial at CERN. Of the LHC's 1232 dipole magnets, half will use sextupole correctors only and the other half will use both sextupoles and decapoles. That means that a total of 616 pairs of decapoles are needed. Like the sextupole...

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

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

    Full Text Available The use of traditional teaching methods, for example the lecture method, does not stimulate critical thinking in student nurses. This problem can be solved by the utilisation of problem-based case study in the classroom/clinical setting. The purpose of this study is to describe guidelines for the implementation of problem-based case study in a clinical setting among first year, comprehensive course students at the Northern Province College of Nursing: Sovenga campus. The research design of this study was qualitative, explorative, descriptive and contextual and was conducted in the following phases: Phase 1: The development and implementation of a program for problem-based case study in the clinical setting; Phase II: The experiences of student nurses who were exposed to problem-based case study in the clinical setting; Phase III: The perceptions of tutors regarding the implementation of problem-based case study in the clinical setting (focus group, and; ase IV: Guidelines for the implementation of problem-based case study. The data from Phases I, II and III were used to formulate guidelines for the implementation of problem-based case study. The sample group consisted of all 69 first year student nurses at the Northern Province College of Nursing: Sovenga campus and ten tutors teaching clinical courses at the same campus. The Tesch (1990 approach is used for data analysis. Nine guidelines for the implementation of a problem-based case study approach were formulated and recommendations for development of an instrument to measure critical thinking in nursing were recommended.

    1986-09-01

    The aim of this study was to determine the efficacy of transcutaneous electrical nerve stimulation (TENS) in the treatment of chronic stable severe angina pectoris. In a short-term study the effect of TENS was studied in 10 male patients with angina pectoris (functional class III and IV). All patients had previously been stabilized on long-term maximal oral treatment. The effects of the treatment were measured by means of repeated bicycle ergometer tests. All patients had an increased working capacity (16-85%), decreased ST segment depression and reduced recovery time during TENS. No adverse effects were observed. A long-term study of TENS on similarly selected patients showed beneficial effects in terms of pain reduction, reduced frequency of anginal attacks, increased physical activity and increased working capacity during bicycle ergometer tests. An invasive study was carried out with respect to systemic and coronary hemodynamics and myocardial metabolism during pacing provoked myocardial ischemia in 13 patients. The results showed that TENS led to an increased tolerance to pacing, improved lactate metabolism, less pronounced ST segment depression. A drop in systolic blood pressure during TENS treatment at identical pacing rates indicated a decreased afterload. An increased coronary flow to ischemic areas in the myocardium was supported by the fact that the rate pressure product during anginal pain increased during TENS.

    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.

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

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

    Outcome-based education is one of the most significant global developments in medical education in recent years. This paper presents four case studies of outcome-based education from medical schools in different parts of the world; Scotland; USA; Pakistan; and Singapore. The outcome-based curricula have either been in place for some time, are evolving or are at the planning proposal stage. The outcomes, change process and implementation of the outcome-based approach are described. Variation in the extent to which each medical school has implemented outcome-based education is discussed and key points for successful implementation are highlighted. This paper is based on the pre-conference symposium "outcome-based curricula: global perspectives" presented by the authors at the 4th Asia Pacific Medical Education Conference (APMEC) in Singapore, 8-11 February, 2007.

    Mackenroth, Uwe

    2004-01-01

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

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

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

    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.

    2004-02-01

    Full Text Available Abstract Background Public SNP databases are frequently used to choose SNPs for candidate genes in the association and linkage studies of complex disorders. However, their utility for such studies of diseases with ethnic-dependent background has never been evaluated. Results To estimate the accuracy and completeness of SNP public databases, we analyzed the allele frequencies of 41 SNPs in 10 candidate genes for obesity and/or osteoporosis in a large American-Caucasian sample (1,873 individuals from 405 nuclear families by PCR-invader assay. We compared our results with those from the databases and other published studies. Of the 41 SNPs, 8 were monomorphic in our sample. Twelve were reported for the first time for Caucasians and the other 29 SNPs in our sample essentially confirmed the respective allele frequencies for Caucasians in the databases and previous studies. The comparison of our data with other ethnic groups showed significant differentiation between the three major world ethnic groups at some SNPs (Caucasians and Africans differed at 3 of the 18 shared SNPs, and Caucasians and Asians differed at 13 of the 22 shared SNPs. This genetic differentiation may have an important implication for studying the well-known ethnic differences in the prevalence of obesity and osteoporosis, and complex disorders in general. Conclusion A comparative analysis of the SNP data of the candidate genes obtained in the present study, as well as those retrieved from the public domain, suggests that the databases may currently have serious limitations for studying complex disorders with an ethnic-dependent background due to the incomplete and uneven representation of the candidate SNPs in the databases for the major ethnic groups. This conclusion attests to the imperative necessity of large-scale and accurate characterization of these SNPs in different ethnic groups.

    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.

    Diagnosing a patient's condition is one of the most important and challenging tasks in medicine. We present a study of the application of collective intelligence in medical diagnosis by applying consensus methods. We compared the accuracy obtained with this method against the diagnostics accuracy reached through the knowledge of a single expert. We used the ontological structures of ten diseases. Two knowledge bases were created by placing five diseases into each knowledge base. We conducted two experiments, one with an empty knowledge base and the other with a populated knowledge base. For both experiments, five experts added and/or eliminated signs/symptoms and diagnostic tests for each disease. After this process, the individual knowledge bases were built based on the output of the consensus methods. In order to perform the evaluation, we compared the number of items for each disease in the agreed knowledge bases against the number of items in the GS (Gold Standard). We identified that, while the number of items in each knowledge base is higher, the consensus level is lower. In all cases, the lowest level of agreement (20%) exceeded the number of signs that are in the GS. In addition, when all experts agreed, the number of items decreased. The use of collective intelligence can be used to increase the consensus of physicians. This is because, by using consensus, physicians can gather more information and knowledge than when obtaining information and knowledge from knowledge bases fed or populated from the knowledge found in the literature, and, at the same time, they can keep updated and collaborate dynamically.

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

    1994-12-01

    As part of the Gas Research Institute Wetland Corridors Program, Argonne National Laboratory conducted field studies on 10 wetland crossings located in six states to document impacts of natural gas pipeline rights-of-way (ROWS) on 15 wetland plant communities. This study is unique in the number, range, ages, and variety of wetland crossings surveyed and compared. Vegetation data and recorded observations were analyzed to reveal patterns associated with age, installation technology, maintenance practices, and wetland type. This report summarizes the findings of this study. Results revealed that ROWs of pipelines installed according to recent wetland regulations rapidly revegetated with dense and diverse plant communities. The ROW plant communities were similar to those in the adjacent natural areas in species richness, wetland indicator values, and percentages of native species. The ROW plant communities developed from naturally available propagules without fertilization, liming, or artificial seeding. ROWs contributed to increased habitat and plant species diversity in the wetland. There was little evidence that they degrade the wetland by providing avenues for the spread of invasive and normative plant species. Most impacts are temporal in nature, decreasing rapidly during the first several years and more slowly thereafter to the extent permitted by maintenance and other ROW activities.

    2011-05-01

    Full Text Available Abstract Background Previous research suggests that children born prematurely or with a low birth weight are more vulnerable to the mental health effects of ambient neighbourhood noise; predominantly road and rail noise, at home. This study used data from the Road Traffic and Aircraft Noise Exposure and Children's Cognition and Health (RANCH study to see if this finding extends to aircraft and road traffic noise at school. Methods Children and their parents from schools around three European airports were selected to represent a range of aircraft and road traffic noise exposure levels. Birth weight and gestation period were merged to create a dichotomous variable assessing 'early biological risk'. Mental health was assessed using the Strengths and Difficulties Questionnaire (SDQ. Complete data were available for 1900 primary school children. Results Children who were 'at risk' (i.e. low birth weight or premature birth were rated as having more conduct problems and emotional symptoms and poorer overall mental health than children not at risk. However, there was no interaction between aircraft or road traffic noise exposure at school and early biological risk. Conclusions Data from the RANCH study suggests that children with early biological risk are not more vulnerable to the effects of aircraft or road traffic noise at school on mental health than children without this risk; however they are more likely to have mental ill-health.

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

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

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

    Full text: A 55-year-old female presented to the Alfred Emergency Department semi-conscious with frank rectal bleeding requiring blood volume replacement. Labelled red blood cell (RBC) scintigraphy was requested in order to locate the site of bleeding. In vitro labelling of 3 mL of patient``s blood was performed (PYP as a diluted tinning agent and 1 GBq of freshly eluted {sup 99}mTc) and suspended red cells were injected. Using a GE Starcam system with high resolution collimation, images were acquired for 30 seconds (2 s per frame) and thereafter continuously for 1. 5 hours (30 s per frame). During imaging, patient history became available revealing portal hypertension, oesophageal and anal varices due to myelofibrosis and previous cholecystectomy. Initial flow images showed bizarre abdominal collateral vessels. Accumulation of labelled RBC over 1.5 hours in the right upper quadrant indicated the hepatic flexure as the site of bleeding. The initial flow study showing major porto-systemic collateral vessels indicated that therapeutic embolisation via angiography would be life threatening. The patient underwent emergency hemicolectomy and has been bleed-free to date. In this case, delayed RBC scintigraphy accurately located the haemorrhage site. However, the initial flow study demonstrating major vessel collateral flow was crucial in contraindicating angiographic embolisation. Surgery was then the only therapeutic option.

    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 ...

  5. 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.

    Background Child undernutrition affects millions of children globally. We investigated associations between suboptimal growth and mortality by pooling large studies. Methods Pooled analysis involving children 1 week to 59 months old in 10 prospective studies in Africa, Asia and South America. Utilizing most recent measurements, we calculated weight-for-age, height/length-for-age and weight-for-height/length Z scores, applying 2006 WHO Standards and the 1977 NCHS/WHO Reference. We estimated all-cause and cause-specific mortality hazard ratios (HR) using proportional hazards models comparing children with mild (−2≤Z<−1), moderate (−3≤Z<−2), or severe (Z<−3) anthropometric deficits with the reference category (Z≥−1). Results 53 809 children were eligible for this re-analysis and contributed a total of 55 359 person-years, during which 1315 deaths were observed. All degrees of underweight, stunting and wasting were associated with significantly higher mortality. The strength of association increased monotonically as Z scores decreased. Pooled mortality HR was 1.52 (95% Confidence Interval 1.28, 1.81) for mild underweight; 2.63 (2.20, 3.14) for moderate underweight; and 9.40 (8.02, 11.03) for severe underweight. Wasting was a stronger determinant of mortality than stunting or underweight. Mortality HR for severe wasting was 11.63 (9.84, 13.76) compared with 5.48 (4.62, 6.50) for severe stunting. Using older NCHS standards resulted in larger HRs compared with WHO standards. In cause-specific analyses, all degrees of anthropometric deficits increased the hazards of dying from respiratory tract infections and diarrheal diseases. The study had insufficient power to precisely estimate effects of undernutrition on malaria mortality. Conclusions All degrees of anthropometric deficits are associated with increased risk of under-five mortality using the 2006 WHO Standards. Even mild deficits substantially increase mortality, especially from infectious diseases

    Full Text Available Abstract Background Suicide and suicide attempts represent a severe problem for public health services. The aim of this study is to determine the socio-demographic and psychopathological variables associated with suicide attempts in the population admitted to a General Hospital. Methods An observational-descriptive study of patients admitted to the A Coruña University Hospital (Spain during the period 1997-2007, assessed by the Consultation and Liaison Psychiatric Unit. We include n = 5,234 admissions from 4,509 patients. Among these admissions, n = 361 (6.9% were subsequent to a suicide attempt. Admissions arising from a suicide attempt were compared with admissions occurring due to other reasons. Multivariate generalised estimating equation logistic regression models were used to examine factors associated with suicide attempts. Results Adjusting by age, gender, educational level, cohabitation status, being employed or unemployed, the psychiatric diagnosis at the time of the interview and the information on previous suicide attempts, we found that the variables associated with the risk of a suicide attempt were: age, psychiatric diagnosis and previous suicide attempts. The risk of suicide attempts decreases with age (OR = 0.969. Psychiatric diagnosis was associated with a higher risk of suicide attempts, with the highest risk being found for Mood or Affective Disorders (OR = 7.49, followed by Personality Disorders (OR = 7.31, and Schizophrenia and Other Psychotic Disorders (OR = 5.03. The strongest single predictive factor for suicide attempts was a prior history of attempts (OR = 23.63. Conclusions Age, psychopathological diagnosis and previous suicide attempts are determinants of suicide attempts.

    Full Text Available Higher education students usually ask for more training based on case studies. This was addressed by designing a specific food safety module (24 hours in which students were shown how to predict microbiological risks in food products i.e. they were asked to determine product shelf-life according to product formulation, preservation methods and consumption habits using predictive microbiology tools. Working groups of four students first identified the main microbiological hazards associated with a specific product. To perform this task, they were given several documents including guides for good hygiene practices, reviews on microbiological hazards in the food sector, flow sheets, etc…  After three-hours of work, the working groups prepared and gave an oral presentation in front of their classmates and professors. This raised comments and discussion that allowed students to adjust their conclusions before beginning the next step of their work. This second step consisted in the evaluation of the safety risk associated with the two major microbiological hazards of the product studied, using predictive microbiology. Students then attended a general lecture on the different tools of predictive microbiology and tutorials (6 hours that made them familiar with the modelling of bacterial growth or inactivation. They applied these tools (9 hours to predict the shelf-life of the studied product according to various scenarios of preservation (refrigeration, water activity, concentration of salt or acid, modified atmosphere, etc… and/or consumption procedures (cooking. The module was concluded by oral presentations of each working group and included student evaluation (3 hours.

    Herb-induced liver injury (HILI) has recently attracted attention due to increasing reports of hepatotoxicity associated with use of phytotherapeutics. Here, we present data on HILI from the Berlin Case-Control Surveillance Study. The study was initiated in 2000 to investigate the serious toxicity of drugs including herbal medicines. Potential cases of liver injury were ascertained in more than 180 Departments of all 51 Berlin hospitals from October 2002 to December 2011. Drug or herb intake was assessed through a standardized face-to-face interview. Drug or herbal aetiology was assessed based on the updated Council for International Organizations of Medical Sciences scale. In ten of all 198 cases of hepatotoxicity included in the study, herbal aetiology was assessed as probable (once ayurvedic herb) or possible (Valeriana five times, Mentha piperita once, Pelargonium sidoides once, Hypericum perforatum once, Eucalyptus globulus once). Mean age was 56.4 ± 9.7 years, and the predominant pattern of liver injury was hepatocellular. No cases of acute liver failure or death were observed. This case series corroborates known risks for ayurvedic herbs, supports the suspected association between Valeriana use and liver injury, and indicates a hepatotoxic potential for herbs such as Pelargonium sidoides, Hypericum perforatum or Mentha piperita that were rarely associated with liver injury before. However, given that possible causality does not prove clinical significance, further studies in this field are needed. PMID:26784183

    Herb-induced liver injury (HILI) has recently attracted attention due to increasing reports of hepatotoxicity associated with use of phytotherapeutics. Here, we present data on HILI from the Berlin Case-Control Surveillance Study. The study was initiated in 2000 to investigate the serious toxicity of drugs including herbal medicines. Potential cases of liver injury were ascertained in more than 180 Departments of all 51 Berlin hospitals from October 2002 to December 2011. Drug or herb intake was assessed through a standardized face-to-face interview. Drug or herbal aetiology was assessed based on the updated Council for International Organizations of Medical Sciences scale. In ten of all 198 cases of hepatotoxicity included in the study, herbal aetiology was assessed as probable (once ayurvedic herb) or possible (Valeriana five times, Mentha piperita once, Pelargonium sidoides once, Hypericum perforatum once, Eucalyptus globulus once). Mean age was 56.4 ± 9.7 years, and the predominant pattern of liver injury was hepatocellular. No cases of acute liver failure or death were observed. This case series corroborates known risks for ayurvedic herbs, supports the suspected association between Valeriana use and liver injury, and indicates a hepatotoxic potential for herbs such as Pelargonium sidoides, Hypericum perforatum or Mentha piperita that were rarely associated with liver injury before. However, given that possible causality does not prove clinical significance, further studies in this field are needed. PMID:26784183

    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.

    2013-01-01

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

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

    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.

    Leishmaniasis in many ways offers a unique vaccine case study. Two reasons for this are that leishmaniasis is a disease complex caused by several different species of parasite that are highly related, thus raising the possibility of developing a single vaccine to protect against multiple diseases. Another reason is the demonstration that a leishmaniasis vaccine may be used therapeutically as well as prophylactically. Although there is no registered human leishmaniasis vaccine today, immunization approaches using live or killed organisms, as well as defined vaccine candidates, have demonstrated at least some degree of efficacy in humans to prevent and to treat some forms of leishmaniasis, and there is a vigorous pipeline of candidates in development. Current approaches include using individual or combined antigens of the parasite or of salivary gland extract of the parasites' insect vector, administered with or without formulation in adjuvant. Animal data obtained with several vaccine candidates are promising and some have been or will be entered into clinical testing in the near future. There is sufficient scientific and epidemiological justification to continue to invest in the development of vaccines against leishmaniasis.

    Dynamic programming is typically applied to optimization problems. As the analytical solutions are generally very difficult, chosen software tools are used widely. These software packages are often third-party products bound for standard simulation software tools on the market. As typical examples of such tools, TOMLAB and DYNOPT could be effectively applied for solution of problems of dynamic programming. DYNOPT will be presented in this paper due to its licensing policy (free product under GPL) and simplicity of use. DYNOPT is a set of MATLAB functions for determination of optimal control trajectory by given description of the process, the cost to be minimized, subject to equality and inequality constraints, using orthogonal collocation on finite elements method. The actual optimal control problem is solved by complete parameterization both the control and the state profile vector. It is assumed, that the optimized dynamic model may be described by a set of ordinary differential equations (ODEs) or differential-algebraic equations (DAEs). This collection of functions extends the capability of the MATLAB Optimization Tool-box. The paper will introduce use of DYNOPT in the field of dynamic optimization problems by means of case studies regarding chosen laboratory physical educational models.

  5. 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 Abstract Background Welfare dependence and low work participation among young people have raised concern in many European countries. Reading and writing difficulties (RWD might make young people vulnerable to work integration problems and welfare dependence through negative influences on education and health. Our main objective of this study was to examine if RWD in adolescence affected the risk of welfare dependence in young adulthood. Methods Baseline information on self-reported RWD, health and family was obtained for 8950 school-attending adolescents in Nord-Trøndelag County, Norway, participating in the Young-HUNT1 survey, 1995-97. All individuals were linked to biological parents to identify siblings and parental education from national registers. Welfare dependence was assessed by the reception of social benefits (medical and economic from the national social insurance database (1998-2007. Only long-term benefits (> 180 days were included. Results The adolescents who reported RWD at baseline were more likely to receive medical or social benefits during follow-up compared with those who did not report RWD. In girls with RWD, the adjusted 5-year risk (at age 24 to 28 for receiving medical benefits was 0.20 (95% confidence interval 0.14-0.26, compared with 0.11 (0.09-0.12 in girls without RWD. In boys the corresponding risks were 0.13 (0.09-0.17 and 0.08 (0.07-0.09. Conclusions The associations between RWD in adolescence and welfare dependence later in life suggest that increased attention should be paid to these problems when discussing the public health aspects of work integration, since there might be a potential for prevention.

    Multiple and inappropriate medications are often the cause for poor health status in the elderly. Medication reviews can improve prescribing. This study aimed to determine if a ten minute medication review by a general practitioner could reduce polypharmacy and inappropriate prescribing in elderly patients. A prospective, randomised study was conducted. Patients over the age of 65 (n = 50) underwent a 10-minute medication review. Inappropriate medications, dosage errors, and discrepancies between prescribed versus actual medication being consumed were recorded. A questionnaire to assess satisfaction was completed following review. The mean number of medications taken by patients was reduced (p < 0.001). A medication was stopped in 35 (70%) patients. Inappropriate medications were detected in 27 (54%) patients and reduced (p < 0.001). Dose errors were detected in 16 (32%). A high level of patient satisfaction was reported. A ten minute medication review reduces polypharmacy, improves prescribing and is associated with high levels of patient satisfaction.

  10. Structural study of CH4, CO2 and H2O clusters containing from several tens to several thousands of molecules

    Torchet, G.; Farges, J.; de Feraudy, M. F.; Raoult, B.

    Clusters are produced during the free jet expansion of gaseous CH4, CO2 or H2O. For a given stagnation temperature To, the mean cluster size is easily increased by increasing the stagnation pressure p0. On the other hand, the cluster temperature does not depend on stagnation conditions but mainly on properties of the condensed gas. An electron diffraction analysis provides information about the cluster structure. Depending on whether the diffraction patterns exhibit crystalline lines or not, the structure is worked out either by using crystallographic methods or by constructing cluster models. When they contain more than a few thousand molecules, clusters show a crystalline structure identical to that of one phase, namely, the cubic phase, known in bulk solid: plastic phase (CH4), unique solid phase (CO2) or metastable cubic phase (H2O). When decreasing the cluster size, the studied compounds behave quite differently: CO2 clusters keep the same crystalline structure, CH4 clusters show the multilayer icosahedral structure wich has been found in rare gas clusters, and H2O clusters adopt a disordered structure different from the amorphous structures of bulk ice. Des agrégats sont produits au cours de la détente en jet libre des gaz CH4, CO2 ou H2O. Pour une température initiale donnée To, on accroît facilement la taille moyenne des agrégats en augmentant la pression initiale po . Par contre, la température des agrégats dépend principalement des propriétés du gaz condensé. Une analyse par diffraction électronique permet l'étude de la structure des agrégats. Selon que les diagrammes de diffraction contiennent ou non des raies cristallines, on a recours soit à des méthodes cristallographiques soit à la construction de modèles d'agrégats. Lorsqu'ils renferment plus de quelques milliers de molécules, les agrégats adoptent la structure cristalline de l'une des phases connues du solide massif et plus précisément la phase cubique : phase plastique pour

    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

    Introdução: A morte fetal tardia é um acontecimento que se mantém na prática diária, apesar de protocolos de vigilância pré-natal e intraparto. Objectivo: Análise dos factores que contribuíram para a causa principal ou condições associadas a morte fetal tardia num período de 10 anos Métodos: Coorte retrospectiva de 208 gestações tardias simples, cujo parto em unidade terciária de cuidados perinatais resultou no nascimento de um nado morto, num período de dez anos. Através de consulta de processo clínico foram analisados dados clínicos, laboratoriais e resultados de estudo anatomo-patológico feto-placentário. Resultados: A incidência de morte fetal tardia foi de 3,5 por cada 1000 nascimentos. Não foram encontradas quaisquer tendências na incidência de MF tardia ao longo do tempo de estudo. Em 12 (5,8%) casos a morte fetal foi um acontecimento intraparto e 72 (35%) eram gestações de termo. Em 14% a gravidez não foi vigiada. A IG média de diagnóstico foi 34 semanas. A principal causa de morte associou-se a patologia fetal, tendo sido identificados factores fetais em 59 casos, destes 25% foram considerados leves para a idade gestacional. Em 24.5% dos casos a causa de morte foi inexplicada. Identificaram-se factores de risco materno em 21% dos casos, a patologia hipertensiva foi frequente e foi associada a idade gestacional precoce (p = 0,028). Conclusões: Não houve oscilações na incidência de morte fetal tardia ao longo dos dez anos avaliados. A incidência foi de 3,5‰, idêntica à descrita em países desenvolvidos. Cerca de um quarto das mortes fetais foram inexplicadas. A patologia materna mais frequente foi a hipertensão crónica.

The book includes extensive references to secondary scholarship, as well as collaborative work by competent scholars and an appended study of the text illustrations by Luboš Bělka From the outset, the book raises a range of interpretive questions of central importance to at least Tibetan and Asian studies. The author describes the plan of the book and its parameters in the Introduction, noting that the manuscript under study does not include tantric perspectives (12, and is instead more oriented to popular understanding and use. This is an important and controversial methodological position, consistent with the formalized one circulated in scholastic and monastic circles that emphasizes secrecy and limited access to fully developed tantric studies. This position can, however, be contrasted with, for example, the uses of texts noted by Cuevas (2003, and further emphasized by Prude (2005:1-3, who suggests more popular use of tantric texts. This view is discussed in detail by others, including Thurman (2006, in his obviously tantric-influenced introduction and translation of the..

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

    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).

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

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

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

    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

    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.

    The Swift Gamma Ray Burst Explorer has proven to be an incredible platform for studying the multiwavelength properties of supernova explosions. In its first ten years, Swift has observed over three hundred supernovae. The ultraviolet observations reveal a complex diversity of behavior across supernova types and classes. Even amongst the standard candle type Ia supernovae, ultraviolet observations reveal distinct groups. When the UVOT data is combined with higher redshift optical data, the relative populations of these groups appear to change with redshift. Among core-collapse supernovae, Swift discovered the shock breakout of two supernovae and the Swift data show a diversity in the cooling phase of the shock breakout of supernovae discovered from the ground and promptly followed up with Swift. Swift observations have resulted in an incredible dataset of UV and X-ray data for comparison with high-redshift supernova observations and theoretical models. Swift's supernova program has the potential to dramaticall...

    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

    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

  4. Orbital dermoid and epidermoid cysts: Case study

    Directory of Open Access Journals (Sweden)

    Veselinović Dragan

    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.

    Seventeen cases of collodion baby are reported. Clinical aspects, complications, treatment, final outcome and family history were studied. We did not observe any clinical features in the collodion baby that could serve as a clue in predicting the final diagnosis. Infections were observed in nine, hypothermia in five and hypernatraemic dehydration in four cases. Skin infection mainly occurred in babies treated with emollients (petrolatum, lanolin and cetomacrogolis cream were used). We therefore recommend treating the collodion baby in a humidified incubator, if necessary with intravenous rehydration, but not to use emollients. The final outcome of these study patients was erythrodermic autosomal recessive lamellar ichthyosis in seven cases (41%), non-erythrodermic autosomal recessive lamellar ichthyosis in three cases (18%), Sjögren-Larsson in one case (6%), epidermolytic hyperkeratosis in one case (6%), acute neonatal variant of Gaucher disease in one case (6%) and normal skin in four cases (24%).

The most common presenting symptoms were obstructive jaundice 6 (35%) and abdominal pain and vomiting 4 (23%). Ultrasound (US) was the initial diagnostic test in all cases with 4 patients requiring further investigations. All patients underwent Roux-en-Y Hepaticojejunostomy. The average length of stay was 11 days. Patients were followed up with Liver Function Tests (LFTS) and US 4-6 weeks post-operatively. Three patients developed complications including post-op collection, high drain output requiring blood transfusion and adhesive bowel obstruction. Our overall experience with choledochal cyst patients has been a positive one with effective management and low complication rates.

  9. How can French agriculture contribute to reducing greenhouse gas emissions? Abatement potential and cost of ten technical measures. Summary of the study report conducted by INRA on behalf of ADEME, MAAF and MEDDE

    International Nuclear Information System (INIS)

    The agricultural industry produces nearly one-fifth of France's greenhouse gas emissions (GHGs). But it also has a strong potential for carbon sequestration. ADEME and the French Ministries for Agriculture and the Environment asked INRA to carry out a study on French agriculture to develop and analyse various measures on farming practices that could boost carbon sequestration and minimise GHGs. There are four key ways agriculture can be a part of the solution of reducing GHG emissions: Lower emissions of nitrous oxide (N2O, a powerful GHG released during fertiliser processing or manure spreading) and methane (CH4, a GHG that comes mostly from livestock); Increase carbon sequestration in soil and biomass; Reduce energy use and produce energy from biomass (agro-fuels or biogas, which lower emissions as substitutes for fossil fuels); Produce materials from biomass. The study specified that eligible measures be based on farming practices that farmers have a say in changing, lead to reductions affecting commercial farms at least in part, do not require major changes to the production system and do not reduce yields by more than 10%. For each of the chosen measures, the study analysed the potential emissions reductions and gains versus tradeoffs for farmers if implemented. The ten measures are centered around nitrogen management (nitrogen fertilizer, pulses), practices that help increase carbon sequestration in soil and biomass (fallow land, agro-forestry, intermediate crops and inter-cropping, pasture management), animal feed (rations that minimise nitrogen excretion or methane production) and the production and consumption of energy by farming (methanation, fossil fuel economies). The study highlights a strong potential for the agricultural sector to reduce emissions through these measures. According to the experts' calculations, if all ten were adopted, France could achieve a cumulative annual reduction of 32 million tons of CO2 equivalent by 2030. However, only part

  11. Using Significant Geologic Hazards and Disasters to Focus Geoethics Case Studies

    Science.gov (United States)

    Cronin, V. S.

    2015-12-01

    Ethics education since classical times has involved the consideration of stories, parables, myths, fables, allegories and histories. These are the ancient equivalents of case studies. Modern case studies are used in applied-ethics courses in law, engineering, business, and science. When used in a geoscience course, geoethical case studies can enrich a student's understanding of the relationships between issues of geoscience, engineering, sociology, business, public policy and law - all with an ethical dimension. Perhaps more importantly, real cases affected real people. Students develop a strong empathetic connection to the people involved, enhancing students' drive to understand the interconnected layers of the cases. Students might begin to appreciate that geoscientists can help to avoid or alleviate human suffering -- that their careers can have meaning and purpose beyond simply earning a paycheck. Geologic disasters in which losses could have been predicted, avoided or minimized are quite effective as cases. Coupling a "disaster" case with a comparable "hazard" case is particularly effective. For example, there are many places along the San Andreas Fault in California where [1] significant coseismic displacement has occurred during historical times, [2] structures that are still inhabited were built along or across active traces prior to the Alquist-Priolo Earthquake Fault Zoning Act in 1971, and [3] inhabited structures have been built legally since 1971 within a few tens of feet of active traces. The question students confront is whether society ought to allow habitable structures to be built very near to a major active fault. This topic allows students to work with issues of law, history, seismology, seismic site response, crustal deformation adjacent to active faults, building codes and, ultimately, ethics. Similar progressions can be developed for other major geologic hazards, both natural and man-made, such as floods, landslides, erosion along rivers and

    Zeakes, Samuel J.

    Noting that a case-study approach can stimulate student thinking and learning, this paper describes how students in a writing-intensive course on parasitology wrote brief medical case studies of parasites already studied for other students to read, evaluate, and identify the parasite. The paper presents a brief description of the course, an…

  13. Femoral shaft fractures in children, treaties with elastic nails of titanium - TENs

    International Nuclear Information System (INIS)

    Femoral shaft fractures are a common and temporarily disabling injury in children. Recent advances in orthopedic traumatology have led us at the Hospital Universitario del Valle, in Cali, Colombia, to perform a case series observational study with the use of a more aggressive approach with the new endomedullar titanium nails (TENs) in children suffering femur shaft fractures, in a closed procedure performed under image intensification. The main purpose of this study was to evaluate the outcome of 30 children treated with these nails. Pediatric femoral shaft fractures are more common in males with approximately a 2.75:1 male to female ratio. The age distribution is bimodal, with peaks in the younger than 5 years and mid-teenage groups (10-14 years) because of the increased incidence of high-energy trauma in teenage children (mean age: 9 years). Overall, TENs allowed rapid mobilization with few complications. The results were excellent or satisfactory in our cases. No child lost rotational alignment in the postoperative period. Irritation of the soft tissue near the knee by the nail tip occurred in one patient. As indications, implantation technique, and aftercare are refined, TENs may prove to be the ideal implant to stabilize most pediatric femur shaft fractures, avoiding the prolonged immobilization and complications of traction and spica cast

    Pityriasis amiantacea was first described in 1832. The disease may be secondary to any skin condition that primarily affects the scalp, including seborrheic dermatitis. Its pathogenesis remains uncertain. We aim to analyze the epidemiological and clinical profiles of patients with pityriasis amiantacea to better understand treatment responses. We identified seven cases of pityriasis amiantacea and a female predominance in a sample of 63 pediatric patients with seborrheic dermatitis followed for an average of 20.4 months. We reported a mean age of 5.9 years. Five patients were female, with a mean age of 9 years. All patients were successfully treated with topic ketoconazole.

    Support from top management and others is agreed to be an important factor in information systems success and failure, but little is written about how it has its effect and how it might be managed to a project's advantage. A recently developed conceptual framework is described. It covers the nature and forms of support, the way support affects project outcomes, the bases on which support is provided, and the strategies by which support may be managed. The framework is used to analyse a case s...

    An ectopic kidney is a rare congenital anomaly that occurs when the kidney fails to ascend to its normal position. Often an ectopic kidney is asymptomatic and the kidney is an unexpected finding during organ recovery. The kidney described in this case report had normal function and could have been used for transplantation, if it had been recovered without 2 renal arteries being damaged because of anatomic variation. The renal vasculature in this type of abnormality usually ascends from the iliac vessels, and this variation in anatomy should be taken into consideration by the recovering surgeon during arterial cannulation for organ flushing.

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

    Full Text Available AIM: To study the significance of platelet count in various fevers and also identify the common causes of fever with thrombocytopenia . MATERIALS AND METHODS: 69 patients who were admitted with fever over 2 months of period from 15th October to15th December 2014 in King George Hospital AMC Visakhapatnam studied retrospectively. RESULTS: INCIDENCE: More than half of the cases (52.2% admitted with fever have thrombocytopenia. SEX: The study reveals that irrespective of sex and size of the sample the presentation of fever with/ without thromb ocytopenia could not found any significant difference . Degree of thrombocytopenia in various etiologies: in the present study it is found that out of 15 cases of falciparum malaria 10 cases had thrombocytopenia. Out of 12 undiagnosed cases 8 cases had thro mbocytopenia. Out of 4 cases of gastro intestinal system 3 cases had thrombocytopenia. In the present study it is significantly found that the highest difference is noticed in the presentation of dengue cases. Out of total sample (69 cases it is found tha t 5cases (7.2% of thrombocytopenia with dengue fever were found against 1case (1.4% of dengue fever with normal plate let count. The present study reveals that there is significant difference among various diseases such as malaria 14 (16.6%, dengue feve r 5 (13.9%, Urinary tract infection 2 (5.6%, undiagnosed cases 8 (22.2%. However severe thrombocytopenia (platelets less than 50,000 is seen in14 cases (38.8%out of 36 cases of fever with thrombocytopenia. Further this study reveals that in the cases of malaria 50% of cases reported as severe thrombocytopenia 7cases (19.4% followed by dengue fever3 cases (8.3%. CONCLUSION: Not only malaria, dengue fever and urinary tract infection can also cause severe thrombocytopenia. Fever cases especially with th rombocytopenia show seasonal variations, they are seen commonly in early winter. Febrile thrombocytopenia still presents as atypical and occult forms making

    Summary Background Significant controversy exists in the literature regarding the role of pregnancy in the prognosis of breast cancer. We designed a matched case-case study, matching pregnancy-associated breast cancer (PABC) cases with breast cancer cases for stage, age, and year of diagnosis. Patients and Methods 39 consecutive cases of PABC were matched with 39 premenopausal cases of breast cancer. Univariate and multivariate survival analyses followed by adjustment for stage, grade, estrogen receptor status, and age at diagnosis, were performed. Results Regarding overall survival (OS), univariate analysis pointed to longer OS in non-PABC cases vs. PABC cases. Accordingly, a more advanced stage predicted shorter survival. In the multivariate analysis, the independent aggravating effect mediated by pregnancy persisted. Interestingly, a post hoc nested analysis within PABC cases indicated that the 3rd trimester pointed to shorter OS. The aforementioned results on OS were also replicated during the examination of relapse-free survival. Conclusion Implementing a matched case-case design, the present study points to pregnancy as a poor prognostic factor for breast cancer. PMID:24415971
