    2007-01-01

    A unified analysis of the enlargement of the Baldone near-surface radioactive waste (RW) repository RADONS considers the interplay of the existing engineering, safety and infrastructure premises, with the foreseen newly socio-technical features. This enlargement consists in construction of two additional RW disposal vaults and in building a long-term storage facility for spent sealed sources at the RADONS territory. Our approach is based on consecutive analysis of following basic elements: - the origin of enlargement - the RADONS safety analysis and a set of optimal socio-technical solutions of Salaspils research reactor decommissioning waste management; - the enlargement - a keystone of the national RW management concept, including the long-term approach; - the enlargement concept - the result of international co-operation and obligations; - arrangement optimization of new disposal and storage space; - environmental impact assessment for the repository enlargement - the update of socio-technical studies. The study of the public opinion revealed: negative attitude to repository enlargement is caused mainly due to missing information on radiation level and on the RADONS previous operations. These results indicate: basic measures to improve the public attitude to repository enlargement: the safety upgrade, public education and compensation mechanisms. A detailed stakeholders engagement and public education plan is elaborated. (author)

  2. Experimental investigation of impingement cooling with turbulators or surface enlarging elements

    For the materials in modern gas turbines to sustain, a considerable amount of cooling is required. In cases where large amounts of heat need to be removed, impingement cooling with its high heat transfer coefficients may be the only alternative. In this work the possibilities of enhancing impingement cooling by introducing surface enlarging - turbulence enhancing elements are examined experimentally. A configuration consisting of a staggered array of 45 impingement jets distributed over 10 rows is used for the purpose. A thermo camera is used to measure the temperature distribution on the target plate, giving an opportunity to separately evaluate the Nusselt number enhancement for different areas. Experiments are conducted for five different area enlarging geometries: triangle, wing, cylinder, dashed rib, and angel, all made from aluminium. Comparison between each area enlarged surface and a flat plate is made, with results presented as Nusselt number enhancement factors. The effect of pumping power required is also investigated in order to maximize the cooling efficiency. Parameters varied are Reynolds number and jet to plate distance. Overall Nusselt number enhancement factors show values of 1 to 1.3, the trend being decreasing with increased jet to plane distance and Reynolds number. When taking into account pumping power the enhancement factors drop to 0.4 to 1.2. The best results are achieved with the rib geometry and when not using a too large value of enlarger height over jet to plate distance (h/z). Row wise evaluation of Nusselt number enhancement shows an increased enhancement with row number and thereby crossflow ratio (Gc/Gj). Typical increases in enhancement of 1 to 1.5 with Gc/Gj from 0 to 0.8 are found. The thermo camera pictures reveal that the enhancement is found in three different areas, on the enlarger base area, the area just downstream the enlarger and in diagonal streaks with increased turbulence caused by the enlargers.

    The choice of a valve with an effective orifice area matching the body surface area and providing efficient hemodynamics is an important factor affecting mortality and morbidity in patients undergoing aortic valve replacement. Our preventative strategy was to implant a larger prosthetic valve by aortic root enlargement using the Nunez procedure in 17 patients between February 2010 and January 2011. The decision to enlarge the aortic root was taken when the 19-mm sizer could not be negotiated easily through the aortic root, or on the basis of body surface area of the patient or type of prosthesis available. Postoperative reductions in peak and mean pressure gradients across aortic valve of 12.8-16.5 and 10.2-12.6 mm Hg, respectively, were observed. Postoperative effective orifice areas of the aortic valves were 1.1-1.5 cm(2). By upsizing the aortic valve, we were able to eliminate patient-prosthesis mismatch in 5 patients, and reduce severe patient-prosthesis mismatch to moderate in 11. Aortic root enlargement is a safe procedure. Therefore, cardiac surgeons should not be reluctant to enlarge the aortic root with an autologous pericardial patch to permit implantation of an adequate size of aortic valve prosthesis, with minimal additional aortic crossclamp time and no added cost.

  7. Dissolution-Enlarged Fractures Imaging Using Electrical Resistivity Tomography (ERT)

    Science.gov (United States)

    Siami-Irdemoosa, Elnaz

    In recent years the electrical imaging techniques have been largely applied to geotechnical and environmental investigations. These techniques have proven to be the best geophysical methods for site investigations in karst terrain, particularly when the overburden soil is clay-dominated. Karst is terrain with a special landscape and distinctive hydrological system developed by dissolution of rocks, particularly carbonate rocks such as limestone and dolomite, made by enlarging fractures into underground conduits that can enlarge into caverns, and in some cases collapse to form sinkholes. Bedding planes, joints, and faults are the principal structural guides for underground flow and dissolution in almost all karstified rocks. Despite the important role of fractures in karst development, the geometry of dissolution-enlarged fractures remain poorly unknown. These features are characterized by an strong contrast with the surrounding formations in terms of physical properties, such as electrical resistivity. Electrical resistivity tomography (ERT) was used as the primary geophysical tool to image the subsurface in a karst terrain in Greene County, Missouri. Pattern, orientation and density of the joint sets were interpreted from ERT data in the investigation site. The Multi-channel Analysis of Surface Wave (MASW) method and coring were employed to validate the interpretation results. Two sets of orthogonal visually prominent joints have been identified in the investigation site: north-south trending joint sets and west-east trending joint sets. However, most of the visually prominent joint sets are associated with either cultural features that concentrate runoff, natural surface drainage features or natural surface drainage.

    2005-03-01

    Swedish Nuclear Fuel and Waste Management Co is currently conducting site characterisation in the Simpevarp area. The area is divided into two subareas, the Simpevarp and the Laxemar subarea. The two subareas are surrounded by a common regional model area, the Simpevarp area. This report describes both the regional area and the subareas. This report is an interim version (model version 1.2) of the description of the surface systems at the Simpevarp area, and should be seen as a background report to the site description of the Simpevarp area, version 1.2, SKB-R--05-08. The basis for this description is quality-assured field data available in the SKB SICADA and GIS databases, together with generic data from the literature. The Surface system, here defined as everything above the bedrock, comprises a number of separate disciplines (e.g. hydrology, geology, topography, oceanography and ecology). Each discipline has developed descriptions and models for a number of properties that together represent the site description. The current methodology for developing the surface system description and the integration to ecosystem models is documented in a methodology strategy report SKB-R--03-06. The procedures and guidelines given in that report were followed in this report. Compared with version 1.1 of the surface system description SKB-R--04-25, this report presents considerable additional features, especially in the ecosystem description (Chapter 4) and in the description of the surface hydrology (Section 3.4). A first attempt has also been made to connect the flow of matter (carbon) between the different ecosystems into an overall ecosystem model at a landscape level. A summarised version of this report is also presented in SKB-R--05-08 together with geological-, hydrogeological-, transport properties-, thermal properties-, rock mechanics- and hydrogeochemical descriptions.

    2013-01-01

    Even though International Commission on Radiological Protection (ICRP) officially adopted a set of adult male and female voxel phantoms as the ICRP reference phantoms, there are several critical limitations due to the nature of voxel geometry and their low voxel resolutions. In order to overcome these limitations of the ICRP phantoms, we are currently developing polygonal surface version of ICRP reference phantoms by directly converting the ICRP voxel phantoms to polygonal surface geometries. Among the many advantages of the ICRP polygonal surface phantom, especially, it is flexible and deformable. In principle, it is, therefore, possible to make the posture-changed ICRP phantoms which can provide more accurate dose values for exposure situations strongly relevant to worker's postures. As a preliminary study for developing the posture-changed ICRP phantoms, in this work we changed the posture of the preliminary version of ICRP male polygon-surface phantom constructed in the previous study. Organ doses were then compared between original and posture-changed phantoms. In the present study, we successfully changed a posture of the preliminary version of ICRP male polygon-surface phantom to the walking posture. From this results, it was explicitly shown that the polygon-surface version of the ICRP phantoms can be sufficiently modified to be various postures with the posture-changing method used in this study. In addition, it was demonstrated that phantom's posture must be considered in certain exposure situations, which can differ dose values from the conventional standing-posture phantom

    Scintigraphic scanning employing technetium-99m sulfur colloid was used to assess the size of the liver and spleen in 32 consecutive patients with rheumatoid arthritis. The data were correlated with clinical and laboratory assessment. Seven patients had enlarged livers, three enlarged spleens. An expected correlation of liver enlargement with Sjogren's syndrome did not materialize. Splenic enlargement and liver enlargement were discordant. Liver enlargement correlation best with elevations of rheumatoid factor as measured by latex fixation. As liver enlargement is not an appreciated feature of rheumatoid arthritis, these findings suggest that hepatomegaly need not necessarily imply adverse treatment results or the development of lymphoproliferative disorders.

    2017-12-01

    Sea surface salinity (SSS) products from Aquarius have had three public releases with progressive improvement in data quality: Versions 2, 3, and 4, with the last one being released in October 2015. A systematic assessment of the Version-4, Level-3 Aquarius SSS product was performed on various spatial and temporal scales by comparing it with gridded Argo products (Lee 2016, Geophys. Res. Lett.). The comparison showed that the consistency of Aquarius Version-4 SSS with gridded Argo products is comparable to that between two different gridded Argo products. However, significant seasonal biases remain in high-latitude oceans. Further improvements are being made by the Aquarius team. Aquarius Version 5.0 SSS is scheduled to be released in October 2017 as the final version of the Aquarius Project. This presentation provides a similar evaluation of Version-5 SSS as reported by Lee (2016) and contrast it with the current Version-4 SSS.

    To evaluate the radiologic findings and clinical feasibility of thymic enlargement in patients with hyperthyroidism. Seven patients with hyperthyroidism and anterior mediastinal bulging revealed by chest radiography were evaluated. The CT findings were analyzed with regard to the shape of the anterior mediastinal mass, surrounding infiltration, and enlargement of mediastinal lymph nodes. Whether or not tumor markers (alpha-fetoprotein, beta-human chorionic gonadotrophin, and chorionic embryonic antigen) showed increased levels was determined, and the size and thickness of the anterior mediastinal mass were measured and compared with previously described age-matched thymus data. In addition, changes in the thyroid gland were evaluated. In all seven patients, anterior mediastinal masses were bi-lobed, with no surrounding infiltration or enlarged mediastinal lymph node, and tumor marker levels showed no increase. The masses were therefore considered to be thymus. In six patients, the size of the thymus exceeded two upper standard deviations of mean value and in one patient, it was smaller than this. In three patients, PCNB (percutaneous needle biopsy) revealed normal thymic tissue and in two, follow-up chest PA demonstrated no interval change. CT showed that in three patients, the thyroid glands were diffusely enlarged. In patients with hyperthyroidism, an anterior mediastinal mass seen on chest radiographs was due to thymic enlargement. The recognition of CT findings of thymic enlargement in such patients may avoid unnecessary biopsy. (author)

    2012-06-01

    Full Text Available The present article aims to explore the general theme of the EU enlargement strategy in the new 2012 European context. Until now, the EU’s enlargement strategy has yielded impressive results. It succeeded in transforming ten central and eastern European countries from post-communism confusion into open-market, mature and effective systems of democratic governments, and even on the economic front, they have also made astonishing progress. It is no doubt that people in the new EU countries live better then before. In this context, the EU must continue the enlargement process to help stabilize the Balkan region that lie beyond its expanded eastern border. No one can deny that major issues concerning western Balkan countries’ accession are still on the table, and they even exert a geopolitical influence of sorts. This makes it all the more important to see stability and regional co-operation there are strategically vital. An all-out effort must now be made to complete the enlargement process and ensure there is no strategic vacuum. This article provides the framework of analyses for the EU problems and the challenges for the Balkans governments as for Brussels.

    The enlargement of suprarenal gland is related to preterm birth and the birth weight. The ultrasound measurement of fetal adrenal gland volume may identify women at risk for impending preterm birth. The aim of our study was to investigate the newborns in the region of western Slovakia followed up due to suprarenal gland enlargement. To set the ratio of prenatally diagnosed suprarenal gland enlargment, postnatal managment and treatment and interventions. The newborns with congenital adrenal hyperplasia were excluded. We have analyzed 6 years of medical records of all cases from the western Slovakia region of suprarenal gland enlargement encountered to 1st Pediatric Department, Children's University Hospital Bratislava Republic in the time period of January 2010 to Janurary 2016. The diagnosis of suprarenal gland enlargement was set by ultrasound examination performed on the 4th postnatal day as an overall screening test. Newborns with positive laboratory screening on congenital adrenal hyperplasia (CAH) were excluded from our study. We analyzed the origin of surarenal gland enlargement, gestation week on the due date, the birth weight and other comorbidities and genetic pathologies in newborns with the enlarged suprarenal glands. There were 6 newborns followed up due to suprarenal gland enlargement. All of the patients had diagnosed the adrenal haemorrhage. Adrenal lesions like adrenal cysts or neuroblastomas were not confirmed. All of the adrenal enlargements were benign with no need of other medical or surgical intervention. None of the newborn patients had other genetic abnormalities, mineral or hormonal imbalances, problems with arterial pressure or haemodynamic instability. All of the patients underwent at least 5 prenatal ultrasound tests and at least 2 postnatal ultrasound measurements. The avarage birth weight was 3030 grams (2700 grams - to 3750 grams). The avarage birth lenght was 50 cm (47 centimeter to 53 cm).The average gestation week (gw) on due date

    Swedish Nuclear Fuel and Waste Management Co (SKB) started site investigations for a deep repository for spent nuclear fuel in 2002 at two different sites in Sweden, Forsmark and Oskarshamn. The investigations should provide necessary information for a license application aimed at starting underground exploration. For this reason, ecosystem data need to be interpreted and assessed into site descriptive models, which in turn are used for safety assessment studies and for environmental impact assessment. Descriptions of the surface system are also needed for further planning of the site investigations. This report describes the surface ecosystems of the Forsmark site (e.g. hydrology, Quaternary deposits, chemistry, vegetation, animals and the human land use). The ecosystem description is an integration of the site and its regional setting, covering the current state of the biosphere as well as the ongoing natural processes affecting the longterm development. Improving the descriptions is important during both the initial and the complete site investigation phase. Before starting of the initial phase in Forsmark, version 0 of the site descriptive model was developed. The results of the initial site investigation phase is compiled into a preliminary site description of Forsmark (version 1.2) in June 2005. This report provides the major input and background to the biosphere description, in the 1.2 version of the Forsmark site description. The basis for this interim version is quality-assured field data from the Forsmark sub area and regional area, available in the SKB SICADA, and GIS data bases as of July 31th 2004 as well as version 1.1 of the Site Descriptive Model. To achieve an ecosystem site description there is a need to develop discipline-specific models by interpreting and analysing primary data.

    Full Text Available Gingival enlargement is a common clinical feature of gingival and periodontal diseases. Currently, more than 20 prescription medications are associated with gingival enlargement. Although the mechanisms of action may be different, the clinical and microscopic appearance of drug-induced gingival enlargement is similar with any drug. Gingival enlargement produces esthetic changes, and clinical symptoms including pain, tenderness, bleeding, speech disturbances, abnormal tooth movement, dental occlusion problems, enhancement of caries development and periodontal disorders. Sodium valproate is considered to produce gingival enlargement, but very rarely. This case report features sodium valproate induced gingival enlargement in a patient with pre-existing chronic periodontitis, who came to the Dental Department, Chinmaya Mission Hospital, Bangalore. The case is special as the patient did not develop the enlargement in spite of taking phenytoin for 1 year and developed enlargement with sodium valproate within 6 months.

    2016-07-01

    Enlarged facial pores remain a common dermatologic and cosmetic concern from acne and rosacea, among other conditions, that is difficult to treat due to the multifactorial nature of their pathogenesis and negative impact on patients' quality of life. Enlarged facial pores are primarily treated through addressing associative factors, such as increased sebum production and cutaneous aging. We review the current treatment modalities for enlarged or dense facial pores, including topical retinoids, chemical peels, oral antiandrogens, and lasers and devices, with a focus on newer therapies.

  17. Bacterial Cell Enlargement Requires Control of Cell Wall Stiffness Mediated by Peptidoglycan Hydrolases.

    Most bacterial cells are enclosed in a single macromolecule of the cell wall polymer, peptidoglycan, which is required for shape determination and maintenance of viability, while peptidoglycan biosynthesis is an important antibiotic target. It is hypothesized that cellular enlargement requires regional expansion of the cell wall through coordinated insertion and hydrolysis of peptidoglycan. Here, a group of (apparent glucosaminidase) peptidoglycan hydrolases are identified that are together required for cell enlargement and correct cellular morphology of Staphylococcus aureus, demonstrating the overall importance of this enzyme activity. These are Atl, SagA, ScaH, and SagB. The major advance here is the explanation of the observed morphological defects in terms of the mechanical and biochemical properties of peptidoglycan. It was shown that cells lacking groups of these hydrolases have increased surface stiffness and, in the absence of SagB, substantially increased glycan chain length. This indicates that, beyond their established roles (for example in cell separation), some hydrolases enable cellular enlargement by making peptidoglycan easier to stretch, providing the first direct evidence demonstrating that cellular enlargement occurs via modulation of the mechanical properties of peptidoglycan. Understanding bacterial growth and division is a fundamental problem, and knowledge in this area underlies the treatment of many infectious diseases. Almost all bacteria are surrounded by a macromolecule of peptidoglycan that encloses the cell and maintains shape, and bacterial cells must increase the size of this molecule in order to enlarge themselves. This requires not only the insertion of new peptidoglycan monomers, a process targeted by antibiotics, including penicillin, but also breakage of existing bonds, a potentially hazardous activity for the cell. Using Staphylococcus aureus, we have identified a set of enzymes that are critical for cellular enlargement. We

  19. CHANGING FROM WITHIN? THE INTRA-ORGANIZATIONAL DYNAMICS OF EU ENLARGEMENT

    Directory of Open Access Journals (Sweden)

    Velibor JAKOVLESKI

    2015-12-01

    Full Text Available This paper opens up the black box of enlargement, focusing on how the intra-organizational relationships among the Council of the European Union, the European Commission, and the European Parliament affect the process of enlargement. Formally speaking, enlargement is an intergovernmental process, suggesting that member states are firmly in control of its outcomes. However, the EU’s supranational actors, specifically the European Parliament and European Commission also attempt to influence enlargement at various stages. I posit that the process of enlargement to the Western Balkans has evolved, influenced by changing constraints which are operating on the aforementioned actors. The added value of this work is in disaggregating the enlargement process based on its institutionalized relationships in both a vertical and horizontal dimension. It provides a supply-side argument for how enlargement policy has evolved from within the EU, rather than simply as a function of external factors.

  1. Wellbore enlargement investigation: Potential analogs to the Waste Isolation Pilot Plant during inadvertent intrusion of the repository

    International Nuclear Information System (INIS)

    Boak, D.M.; Dotson, L.; Aguilar, R.

    1997-01-01

    This study involved the evaluation and documentation of cases in which petroleum wellbores were enlarged beyond the nominal hole diameter as a consequence of erosion during exploratory drilling, particularly as a function of gas flow into the wellbore during blowout conditions. A primary objective was to identify analogs to potential wellbore enlargement at the Waste Isolation Pilot Plant (WIPP) during inadvertent human intrusion. Secondary objectives were to identify drilling scenarios associated with enlargement, determine the physical extent of enlargement, and establish the physical properties of the formation in which the enlargement occurred. No analogs of sufficient quality to establish quantitative limits on wellbore enlargement at the WIPP disposal system were identified. However, some information was obtained regarding the frequency of petroleum well blowouts and the likelihood that such blowouts would bridge downhole, self-limiting the surface release of disposal-system material. Further work would be necessary, however, to determine the conditions under which bridging could occur and the extent to which the bridging might be applicable to WIPP. In addition, data on casing sizes of petroleum boreholes in the WIPP vicinity support the use of a 12-1/4 inch borehole size in WIPP performance assessment calculations. Finally, although data are limited, there was no evidence of significant wellbore enlargement in any of three blowouts that occur-red in wellbores in the Delaware Basin (South Culebra Bluff Unit No. 1, Energy Research and Development Administration (ERDA) 6, and WIPP 12)

    The purpose of this study is to describe the rib changes seen in patients with brochopulmonary dysplasia (BPD). Serial chest radiographs of nine premature infants with BPD who showed diffuse rib enlargement were reviewed for hyperinflation, which was compared with the observed degree of rib enlargement. Vibrator chest physiotherapy was performed in all cases, and five infants underwent conventional ventilation plus high frequency oscillatory ventilation therapy. Their calcium level was normal whereas alkaline phosphatase and phosphate levels were high. In all infants except one, liver enzyme levels were normal. For the treatment of patent ductus arteriosus, infection, and BPD, medications including indomethacin, antibiotics, and dexamethasone were administered. Vitamin D was given to all patients with total parenteral nutrition. Rib enlargement was found to be severe (n=3D4), moderate (n=3D3), or mild (n=3D2) with undulating margins or posterior tapering (n=3D2). Hyperinflation was noted in eight patients, in seven of whom it was moderate to severe. Among these seven, rib enlargement was severe (n=3D2), moderate (n=3D3), or mild (n=3D2). In one infant with mild hyperinflation, rib enlargement was severe. Bilateral irregular infiltrates and atelectases were noted in all patients. In BPD patients, rib enlargement may be seen. In order to differentiate this process from systemic bone disease or bony dysplasia, an awareness of the rib changes occurring in patients with BPD may be important. (author)

    Full Text Available Introduction: Gingival enlargement (GA is a benign condition of the oral cavity that is characterized by the excessive growth of the gingiva in mass and volume. This lesion is not only caused by hereditary factors or poor oral hygiene, but also by the intake of medications, including antihypertensive, anticonvulsant and immunosuppressive drugs. Objective: To sensitize the prevention or early care in patients with pathologies that merit the use of antihypertensive and anticonvulsants in conjunction with the dentist, to treat or avoid the drug-induced gingival enlargement (DIGE. Materials and methods: A series of clinical cases of patients with gingival enlargement by various drugs are reported, including Phenytoin, Amlodipine and Nifedipine. Periodontal and gingivectomy hygienic phase measures were applied to obtain better effects. Results: Satisfactory results were obtained with a considerable decrease in DIGE. Conclusions: The integral management is important in conjunction with the treating physician to follow up the drug that can be generating gingival enlargement. It is necessary to employ an initial approach with strategies of periodontal hygiene, and in severe cases and, as last resort, the periodontal surgery with gingivectomy and gingivoplasty.

    Highlights: → The influence of impeller enlargement is evaluated numerically and experimentally. → Variation equations of the operation points for enlarged impellers are derived. → Impeller enlargement leads to louder fan noise due to reduced impeller-volute gap. - Abstract: The influence of enlarged impeller in unchanged volute on G4-73 type centrifugal fan performance is investigated in this paper. Comparisons are conducted between the fan with original impeller and two larger impellers with the increments in impeller outlet diameter of 5% and 10% respectively in the numerical and experimental investigations. The internal characteristics are obtained by the numerical simulation, which indicate there is more volute loss in the fan with larger impeller. Experiment results show that the flow rate, total pressure rise, shaft power and sound pressure level have increased, while the efficiency have decreased when the fan operates with larger impeller. Variation equations on the performance of the operation points for the fan with enlarged impellers are suggested. Comparisons between experiment results and the trimming laws show that the trimming laws for usual situation can predict the performance of the enlarged fan impeller with less error for higher flow rate, although the situation of application is not in agreement. The noise frequency analysis shows that higher noise level with the larger impeller fan is caused by the reduced impeller-volute gap.

  12. Use of Macrolane VRF 30 in emicircumferential penis enlargement.

    Science.gov (United States)

    Sito, Giuseppe; Marlino, Sergio; Santorelli, Adriano

    2013-02-01

    Penis enlargement is increasingly in demand. Methods for penis enlargement can be classified into surgical, nonsurgical (filling), and mechanical. Each method has shown only relatively successful results. A new formulation of injectable, stabilized, hyaluronic acid (HA)-based, nonanimal gel is available that may have applications for this use. The authors propose a new technique for emicircumferential-injection filling of the penis and assess the safety and efficacy of this procedure compared with lipofilling. The authors retrospectively reviewed the charts of 83 patients who underwent penis enlargement with either their HA-injection technique or lipofilling between December 2007 and July 2011. Safety, efficacy, and patient satisfaction were assessed. The circumferential enlargement obtained from both techniques ranged from 3.2 to 4.5 cm, with a decrement during erection. In all patients, the increase in penis length ranged from 1.8 to 3.6 cm. No complications were seen in patients treated with HA, whereas 8 patients treated with lipofilling developed granuloma, and another experienced fat necrosis. The vast majority (n = 72) of patients reported being "very satisfied" with the results. The ideal technique for penis enlargement should be nonsurgical, with a satisfactory and predictable result, a low rate of complications, and long-term stability. Emicircumferential enlargement with HA filler meets these requirements. However, results have been durable but not definitive, and repeated treatment (with associated costs) is necessary.

  13. Normalization of Bilateral Adrenal Gland Enlargement after Treatment for Cryptococcosis

    2017-01-01

    Full Text Available Cryptococcosis usually occurs in immunocompromised patients and can cause enlargement of the adrenal glands, although the morphologic changes after treatment have not been reported in detail. We report the case of 24-year-old man with fevers, headaches, and impaired consciousness who had been treated with glucocorticoids for a protein-losing gastroenteropathy. The cerebrospinal fluid analysis revealed cryptococcal meningitis. Computed tomography showed bilateral adrenal enlargement. A retrospective analysis revealed that the enlargement had been detected 5 months before admission and gradually increased. The enlargement was improved with antifungal therapy and normalized 6 months later. This is the first report describing morphological changes in the adrenal glands associated with cryptococcal meningitis. Adrenal enlargement by cryptococcosis can be improved without any abnormal findings, including calcifications, which may be a unique characteristic from other diseases, including tuberculosis.

  14. Ubx regulates differential enlargement and diversification of insect hind legs.

    Directory of Open Access Journals (Sweden)

    Najmus Mahfooz

    2007-09-01

    Full Text Available Differential enlargement of hind (T3 legs represents one of the hallmarks of insect evolution. However, the actual mechanism(s responsible are yet to be determined. To address this issue, we have now studied the molecular basis of T3 leg enlargement in Oncopeltus fasciatus (milkweed bug and Acheta domesticus (house cricket. In Oncopeltus, the T3 tibia displays a moderate increase in size, whereas in Acheta, the T3 femur, tibia, and tarsus are all greatly enlarged. Here, we show that the hox gene Ultrabithorax (Ubx is expressed in the enlarged segments of hind legs. Furthermore, we demonstrate that depletion of Ubx during embryogenesis has a primary effect in T3 legs and causes shortening of leg segments that are enlarged in a wild type. This result shows that Ubx is regulating the differential growth and enlargement of T3 legs in both Oncopeltus and Acheta. The emerging view suggests that Ubx was co-opted for a novel role in regulating leg growth and that the transcriptional modification of its expression may be a universal mechanism for the evolutionary diversification of insect hind legs.

    2015-01-01

    Achondroplasia is a skeletal dysplasia with diminished growth of the skull base secondary to defective enchondral bone formation. This leads to narrowing of the foramen magnum and jugular foramina, which further leads to ventricular dilatation and prominence of the emissary veins. The primary goal of our study was to determine a correlation between the degree of ventricular dilatation, jugular foramina and foramen magnum narrowing, as well as emissary vein enlargement. Conventional T2-weighted MR images were evaluated for surface area of the foramen magnum and jugular foramina, ventricular dilatation, and emissary veins enlargement in 16 achondroplasia patients and 16 age-matched controls. Ratios were calculated for the individual parameters using median values from age-matched control groups to avoid age as a confounder. Compared to age-matched controls, in children with achondroplasia, the surface area of the foramen magnum (median 0.50 cm(2), range 0.23-1.37 cm(2) vs. 3.14 cm(2), 1.83-6.68 cm(2), p achondroplasia, (1) the variation in ventricular dilatation may be related to an unquantifiable interdependent relationship of emissary vein enlargement, venous channel narrowing, and foramen magnum compression and (2) stable ventricular size facilitated by interdependent factors likely obviates the need for ventricular shunt placement.

    2013-01-01

    This report presents a new version of surface mineral maps derived from HyMap imaging spectrometer data collected over Afghanistan in the fall of 2007. This report also describes the processing steps applied to the imaging spectrometer data. The 218 individual flight lines composing the Afghanistan dataset, covering more than 438,000 square kilometers, were georeferenced to a mosaic of orthorectified Landsat images. The HyMap data were converted from radiance to reflectance using a radiative transfer program in combination with ground-calibration sites and a network of cross-cutting calibration flight lines. The U.S. Geological Survey Material Identification and Characterization Algorithm (MICA) was used to generate two thematic maps of surface minerals: a map of iron-bearing minerals and other materials, which have their primary absorption features at the shorter wavelengths of the reflected solar wavelength range, and a map of carbonates, phyllosilicates, sulfates, altered minerals, and other materials, which have their primary absorption features at the longer wavelengths of the reflected solar wavelength range. In contrast to the original version, version 2 of these maps is provided at full resolution of 23-meter pixel size. The thematic maps, MICA summary images, and the material fit and depth images are distributed in digital files linked to this report, in a format readable by remote sensing software and Geographic Information Systems (GIS). The digital files can be downloaded from http://pubs.usgs.gov/ds/787/downloads/.

  17. Treatment and utilization of waste waters of surface mines in Ukraine

    Energy Technology Data Exchange (ETDEWEB)

    Khmel' , N S

    1981-01-01

    Waste water of brown coal surface mines in the Dnieper basin is characterized. The water's pH value is 7, alkalinity ranges from 5.1 to 5.9 mg equivalent/1, it has no odor, a low mineralization level ranging from 1000 to 1100 mg/l. Concentration of mechanical impurities (suspended matter) ranges from 90 to 900 mg/l, and its maximum level can reach 5000 mg/l. An improved design of tanks in which waste water from surface mines is treated, and mechanical impurities settle, is proposed. Conventional design of a water sedimentation tank consists of a long ditch in which suspended matter settles, and a rectangular water reservoir at its end. In the improved version the long ditch is enlarged in some places to create additional tanks and to reduce velocity of flowing waste water. This improvement increases the amount of suspended matter which settles in the ditch and in its enlarged zones. When water reaches the rectangular sedimentation tank at the end of the system its suspended matter content is reduced to 40-45 mg/l. Formulae used to calculate dimensions of water treatment system, gradient of the ditch and size of sedimentation tank are presented. Methods of discharging treated waste water to surface water, rivers and stagnant waters, are evaluated. (In Russian)

    Full Text Available This article provides a critical review of the “terms” of the ongoing EU enlargement, in the light of the European public interest. The European public interest ought to include the prospective (Central European members, within a perspective of an enlarged Union in 2010, or so. The following forms a personalised summary of a major report published (in Dutch in September 2001 by the WRR in The Hague (a think-tank, formally under the Dutch Prime Minister, but by statute fully independent. The author was one of the lead-writers of this report. The present article merely focuses on the policy recommendations of the report. It is hoped that these kinds of critical analyses will help to stimulate solid policy debate on the EU in Romania, on the road to EU membership. The article discusses why the notion of a “core-acquis” would improve the enlargement strategy; the application of the core acquis to the internal market, environment and justice and home affairs; judicial and administrative capacity; accession to “euro-land”; the rapid reform of the CAP; a reform of “cohesion” approaches; and a note on the EU budgetary implications.

    To evaluate the frequency of enlarged hilar or mediastinal lymph nodes in heavy smokers (more than 10 pack years) compared with non- smokers. In a prospective study the CT findings of 88 consecutive patients (44 heavy smokers, 44 non- smokers) were analysed. Exclusion criteria were history of thoracic malignancy, sarcoidosis, occupational dust exposure or clinical evidence of pneumonia. Prevalence, size and site of enlarged lymph nodes were assessed by multidetector computed tomography (MDCT) and correlated with the cigarette consumption and the CT- findings of bronchitis and emphysema. Twenty-three of the 44 heavy smokers (52%) showed enlarged mediastinal lymph nodes. Non- smokers showed enlarged lymph nodes in 9% (4/44). The most common site of enlarged lymph nodes was the regional station 7 according to the ATS mapping (subcarinal). The difference between the frequency of enlarged lymph nodes in heavy smokers and non- smokers was significant (chi- square 19.3, p < 0.0001). Airway wall thickening and emphysema were often associated with an increased number of enlarged nodes. The present study demonstrates that enlarged mediastinal lymph nodes may occur in a rather high percentage of heavy smokers, especially in those with a MDCT finding of severe bronchitis. (orig.)

    Generalized gingival enlargement is characterized by massive and exuberant gingival overgrowth that poses social, aesthetic, phonetic and functional problems for the patient. Therefore, it requires meticulous management. Objective: To describe the surgical management of generalized gingival enlargement by electrosurgical excision of patients presenting to a tertiary care centre. Study Design: Case series. Materials and Methods: The study was conducted at the Department of Oral and Maxillofacial Surgery, de'Montmorency College of Dentistry, Lahore, from January 2010 to December 2012. A total of sixteen patients were operated by using electrosurgical approach under general anaesthesia for surgical excision of generalized gingival enlargement. Results: All of the sixteen patients, 11 males and 5 females, showed excellent healing postoperatively without any recurrent gingival overgrowth. Discussion: To the best of our knowledge, the current study presents the largest case series of generalized gingival enlargement. Most of these cases were with massive disease due to lack of information of the study population about their disease, delay in referral by the general dental practitioners, painless and innocent nature of the problem. Early referral of such patients to tertiary care centers can prevent the patients from social and psychological embarrassment. Conclusion: Electrosurgical excision is an excellent surgical technique for management of generalized gingival enlargement. Moreover, cross comparative studies are required to establish some diagnostic and therapeutic standards for such patients. (author)

    Increasing the number of enlarged pores causes cosmetic problems. The difference in the number of enlarged pores according to facial site, age, and sex is unclear. To analyze the distribution of the number of enlarged pores according to facial site, age, and sex. We analyzed the number of the enlarged pores and the percentage of wrinkles in the nose, forehead, and cheek from 434 polarized images. The measurement results were analyzed according to site, age, and sex. Relationship between enlarged pore counts and wrinkle severity was also analyzed. The study was conducted by using DermaVision,™ which can take cross-polarization, parallel polarization, and ultraviolet light images. The enlarged pores of the nose and forehead were more prominent than in the cheeks. Pore counts were increased with age, and the increment was significant between the 30's and 40's. There was no significant difference by gender. Enlarged pore counts were related to wrinkle severity. The number of enlarged pores differs depending on body site and increased with age. The enlarged pore counts correlate with wrinkle severity and the correlation varies depending on the body site. © 2018 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    The Surface Ocean CO2 Atlas (SOCAT) is a synthesis of quality-controlled f CO2 (fugacity of carbon dioxide) values for the global surface oceans and coastal seas with regular updates. Version 3 of SOCAT has 14.7 million f CO2 values from 3646 data sets covering the years 1957 to 2014. This latest version has an additional 4.6 million f CO2 values relative to version 2 and extends the record from 2011 to 2014. Version 3 also significantly increases the data availability for 2005 to 2013. SOCAT has an average of approximately 1.2 million surface water f CO2 values per year for the years 2006 to 2012. Quality and documentation of the data has improved. A new feature is the data set quality control (QC) flag of E for data from alternative sensors and platforms. The accuracy of surface water f CO2 has been defined for all data set QC flags. Automated range checking has been carried out for all data sets during their upload into SOCAT. The upgrade of the interactive Data Set Viewer (previously known as the Cruise Data Viewer) allows better interrogation of the SOCAT data collection and rapid creation of high-quality figures for scientific presentations. Automated data upload has been launched for version 4 and will enable more frequent SOCAT releases in the future. High-profile scientific applications of SOCAT include quantification of the ocean sink for atmospheric carbon dioxide and its long-term variation, detection of ocean acidification, as well as evaluation of coupled-climate and ocean-only biogeochemical models. Users of SOCAT data products are urged to acknowledge the contribution of data providers, as stated in the SOCAT Fair Data Use Statement. This ESSD (Earth System Science Data) “living data” publication documents the methods and data sets used for the assembly of this new version of the SOCAT data collection and compares these with those used for earlier versions of the data collection (Pfeil et al., 2013; Sabine et al., 2013; Bakker et al., 2014).

    Full Text Available In the surgery of aortic valve replacement is always attempted, as much as possible, to implant the larger prosthesis with the mains goals to enhance the potential benefits, to minimise transvalvular gradient, decrease left ventricular size and avoid the phenomenon of patient-prosthesis mismatch. Implantation of an ideal prosthesis often it is not possible, due to a small aortic annulus. A variety of aortic annulus enlargement techniques is reported to avoid patient-prosthesis mismatch. We present the case that has submitted four three times open heart surgery. We used Manouguian technique to enlarge aortic anulus with excellent results during the fourth time of surgery.

  11. The EU and ‘Enlargement Fatigue’: Why Has the European Union Not Been Able to Counter ‘Enlargement Fatigue’?

    Directory of Open Access Journals (Sweden)

    Anna Szolucha

    2010-05-01

    Full Text Available This article provides an up-to-date overview of the problems connected with European integration. It focuses on the phenomenon of ‘enlargement fatigue’ and examines its meaning as utilised by the media, EU officials and academics. The article argues that ‘enlargement fatigue’ is not a new concept since the EU has witnessed many 'symptoms' of fatigue at multiple times in its history. The two main arguments that are often presented in order to explain why the EU has not been able to counter ‘enlargement fatigue’, namely the insufficiently tight conditionality applied to prospective members and the EU's crisis of confidence and accountability after the failed attempt to introduce the Constitutional Treaty and prolonged Lisbon Treaty ratification process, are insufficient to explain why fatigue has been so persistent a phenomenon. This article argues that the EU's failure to develop a new vision of the organisation and adjust its structural design accordingly is a reason why the Union has not dealt successfully with fatigue. Such a vision would encompass notions of “variable geometry”, “avant-garde groups” and make European borders flexible and fuzzy.

    Background Previous studies suggested that enlarged perivascular spaces are neuroimaging markers of cerebral small vessel disease. However, it is not clear whether enlarged perivascular spaces are associated with cognitive impairment. We aimed to determine the cross-sectional relationship between enlarged perivascular spaces and small vessel disease, and to investigate the relationship between enlarged perivascular spaces and subsequent cognitive impairment in patients with recent cerebral ischemic event. Methods Anonymized data were accessed from the virtual international stroke trial archive. We rated number of lacunes, white matter hyperintensities, brain atrophy, and enlarged perivascular spaces with validated scales on magnetic resonance brain images after the index stroke. We defined cognitive impairment as a mini mental state examination score of ≤26, recorded at one year post stroke. We examined the associations between enlarged perivascular spaces and clinical and imaging markers of small vessel disease at presentation and clinical evidence of cognitive impairment at one year using linear and logistic regression models. Results We analyzed data on 430 patients with mean (±SD) age 64.7 (±12.7) years, 276 (64%) males. In linear regression analysis, age (β = 0.24; p cognitive impairment at one year after adjusting for clinical confounders (OR = 1.72, 95% CI = 1.22-2.42) and for clinical and imaging confounders (OR = 1.54; 95% CI = 1.03-2.31). Conclusions Our data show that in patients with ischemic cerebral events, enlarged perivascular spaces are cross-sectionally associated with age, hypertension, and white matter hyperintensities and suggest that enlarged perivascular spaces in the basal ganglia are associated with cognitive impairment after one year.

  14. Mitral-aortic annular enlargement: modification of Manouguian's technique

    2002-01-01

    Full Text Available We hereby present a technical modification for mitral-aortic annular enlargement. The mitral valve is replaced through the retro-septal approach, avoiding patches for left atrial roof closure. We report a mitral-aortic valve replacement in a patient whose original annuli would preclude adequate prostheses. The simultaneous annular enlargement may be necessary for avoiding patient-prosthesis mismatch and for reconstructing destroyed mitral and aortic annuli. The technique may minimize the risk of bleeding and of paravalvular leakage, using an approach well known to cardiac surgeons.

    Ventricular enlargement was determined using linear measurement on MR images in a total of 71 patients with affective disorders, including bipolar affective disorder (41) and depression (30). Fourty-one healthy persons served as controls. Evans ratio, Huckman number and minimum distance of caudate nuclei (MDCN) were used as indices for ventricular enlargment. No significant difference in Evans ratio was observed between both the group of bipolar affective disorder and the group of depression and the control group. Nor did it correlate with age in any of the groups. Huckman number was significantly higher in the group of bipolar affective disorder than the other two groups. It positively correlated with age in the group of depression. MDCN was significantly increased in the group of bipolar affective disorder, as compared with the control group; and there was a positive correlation between MDCN and age in both the group of dipolar affective disorder and the group of depression. In conclusion, ventricular enlargement was dependent upon aging in affetive disorder patients. This tendency was more noticeable in the group of depression. In addition, atrophy of the caudate nuclei was likely to be severer in the group of dipolar affective disorder than the group of depression. (N.K.)

    Sputter deposited photocatalytic thin films offer high adherence and mechanical stability, but typically are outperformed in their photocatalytic properties by colloidal TiO2 nanostructures, which in turn typically suffer from problematic removal. Here we report on thermally controlled nanocrack formation as a feasible and batch applicable approach to enhance the photocatalytic performance of well adhering, reactively sputtered TiO2 thin films. Networks of nanoscopic cracks were induced into tailored columnar TiO2 thin films by thermal annealing. These deep trenches are separating small bundles of TiO2 columns, adding their flanks to the overall catalytically active surface area. The variation of thin film thickness reveals a critical layer thickness for initial nanocrack network formation, which was found to be about 400 nm in case of TiO2. The columnar morphology of the as deposited TiO2 layer with weak bonds between respective columns and with strong bonds to the substrate is of crucial importance for the formation of nanocrack networks. A beneficial effect of nanocracking on the photocatalytic performance was experimentally observed. It was correlated by a simple geometric model for explaining the positive impact of the crack induced enlargement of active surface area on photocatalytic efficiency. The presented method of nanocrack network formation is principally not limited to TiO2 and is therefore seen as a promising candidate for utilizing increased surface area by controlled crack formation in ceramic thin films in general.

    Muscle enlargement and hypertrophy are rare findings in neurogenic lesions. The two in combination have been reported in cases of peripheral nerve lesions, polyneuropathy, and poliomyelitis. True and pseudo muscle hypertrophy are the two possible etiologies, whereas infiltration, stretch, or exercise of the muscle are the causative factors. We report two cases of unilateral calf enlargement, one occurring after surgery for S1 radiculopathy with associated cramping, and the other after poliomyelitis.

    Aim: To assess the prevalence and the department's detection rate of adrenocortical hyperplasia. Materials and methods: All computed tomography (CT) examinations of the adrenal glands between February and April 2011 were reviewed. The study excluded patients with known underlying cancer, abdominal trauma, or endocrine disease. The adrenal gland was deemed enlarged if its body was greater than 10 mm diameter, or a limb greater than 5 mm. Results: There were a total of 564 eligible CT studies during this period. A total of 64 cases of incidental adrenal enlargement were found giving a prevalence of 11.3%. Only nine cases were reported in the contemporaneous CT report. Conclusion: The results of the present study show that incidental adrenal enlargement has a significant prevalence. It is often dismissed during reporting, and awareness needs to be raised in the radiological community. Equally, the clinical and biochemical significance needs to be assessed with endocrine correlation

    Stereotactic radiotherapy/radiosurgery (RT/ES) is an effective technique for treating craniopharyngiomas (CPs). However, enlargement of the cystic part of the tumor occurs in some cases after irradiation. The enlargement may be transient and not require treatment or be a true relapse requiring treatment. In this study, we performed a retrospective analysis of 79 pediatric patients who underwent stereotactic RT or RS after resection of craniopharyngioma. Five-year relapse-free survival after complex treatment of CP was 86%. In the early period after irradiation, 3.5 months (2.7-9.4) on average, enlargement of the cystic component of the tumor was detected in 10 (12.7%) patients; in 9 (11.4%) of them, the enlargement was transient and did not require treatment; in one case, the patient underwent surgery due to reduced visual acuity. In 8 (10.1%) patients, an increase in the residual tumor (a solid component of the tumor in 2 cases and a cystic component of the tumor in 6 cases) occurred in the long-term period after irradiation - after 26.3 months (16.6-48.9) and did not decrease during follow-up in none of the cases, i.e. continued growth of the tumor was diagnosed. A statistical analysis revealed that differences in the terms of transient enlargement and true continued growth were statistically significant (pcraniopharyngioma cyst in the early period (up to 1 year) after RT/RS is usually transient and does not require surgical treatment (except cases where worsening of neurological symptoms occurs, or occlusive hydrocephalus develops).

    The Global Energy Balance Archive (GEBA) is a database for the central storage of the worldwide measured energy fluxes at the Earth's surface, maintained at ETH Zurich (Switzerland). This paper documents the status of the GEBA version 2017 dataset, presents the new web interface and user access, and reviews the scientific impact that GEBA data had in various applications. GEBA has continuously been expanded and updated and contains in its 2017 version around 500 000 monthly mean entries of various surface energy balance components measured at 2500 locations. The database contains observations from 15 surface energy flux components, with the most widely measured quantity available in GEBA being the shortwave radiation incident at the Earth's surface (global radiation). Many of the historic records extend over several decades. GEBA contains monthly data from a variety of sources, namely from the World Radiation Data Centre (WRDC) in St. Petersburg, from national weather services, from different research networks (BSRN, ARM, SURFRAD), from peer-reviewed publications, project and data reports, and from personal communications. Quality checks are applied to test for gross errors in the dataset. GEBA has played a key role in various research applications, such as in the quantification of the global energy balance, in the discussion of the anomalous atmospheric shortwave absorption, and in the detection of multi-decadal variations in global radiation, known as global dimming and brightening. GEBA is further extensively used for the evaluation of climate models and satellite-derived surface flux products. On a more applied level, GEBA provides the basis for engineering applications in the context of solar power generation, water management, agricultural production and tourism. GEBA is publicly accessible through the internet via http://www.geba.ethz.ch. Supplementary data are available at https://doi.org/10.1594/PANGAEA.873078.

  5. Enlarging the underground hydroelectric plant at Villarino, Spain

    Energy Technology Data Exchange (ETDEWEB)

    Oriard, L.L.

    1997-05-01

    Near the village of Villarino de los Aires, in the province of Salamanca, Spain, was an existing underground hydroelectric power plant. A major enlargement was undertaken to increase the electrical generating capacity, under a contract awarded to a joint venture of Dragados y Construcciones, S. A. (Spain), Entrecanales y Tavora, S. A. (Spain), and S.A. Conrad Zschokke (Switzerland). The enlargement required the excavation of a large and complex underground system of tunnels, shafts and chambers adjacent to existing facilities and interconnected with these facilities. The existing machine hall and transformer chamber were both extended, requiring the blasting of the existing end walls. The drilling, blasting and excavating of the underground system had to be done without damage to existing underground chambers and tunnels, or any of the existing structures, equipment or instrumentation facilities, often within just a few feet of the blasting. This required careful control of vibrations, airblast overpressures and dust. Because the only available non-electric detonating systems were found to be unreliable and unsafe, electric systems would be preferred if they could be used in a safe manner at this site. High electrical potentials existed at the site, and the facilities could not be shut down. Electrical fields were studied carefully, both in the underground environment and above the ground surface. Based on these results, it was concluded that electric detonators could be used if special blasting procedures were developed and followed. In accord with contracting practices of this Spanish agency, the contract was not awarded to the lowest bidder, but to the bidder who demonstrated the best understanding of the project and who presented the best technical proposal for conducting the work to a conclusion that would be satisfactory to the owner. The development of the technical proposal was a two-month effort for a technical group and support staff, prepared in Madrid.

    Full Text Available Honeybee royal jelly is reported to have body-enlarging effects in holometabolous insects such as the honeybee, fly and silkmoth, but its effect in non-holometabolous insect species has not yet been examined. The present study confirmed the body-enlarging effect in silkmoths fed an artificial diet instead of mulberry leaves used in the previous literature. Administration of honeybee royal jelly to silkmoth from early larval stage increased the size of female pupae and adult moths, but not larvae (at the late larval stage or male pupae. We further examined the body-enlarging effect of royal jelly in a non-holometabolous species, the two-spotted cricket Gryllus bimaculatus, which belongs to the evolutionarily primitive group Polyneoptera. Administration of royal jelly to G. bimaculatus from its early nymph stage enlarged both males and females at the mid-nymph and adult stages. In the cricket, the body parts were uniformly enlarged in both males and females; whereas the enlarged female silkmoths had swollen abdomens. Administration of royal jelly increased the number, but not the size, of eggs loaded in the abdomen of silkmoth females. In addition, fat body cells were enlarged by royal jelly in the silkmoth, but not in the cricket. These findings suggest that the body-enlarging effect of royal jelly is common in non-holometabolous species, G. bimaculatus, but it acts in a different manner than in holometabolous species.

    The polar recesses, superior and inferior to lumbar facet joints, are filled by fat pads from which fat-filled synovial folds project between the articular surfaces for a distance of two to four millimetres. The intracapsular superior recess lies between the ligamentum flavum and the lamina above. The extracapsular inferior recess lies on the back of the lamina below and communicates with the joint through a hole in the inferior capsule. The intracapsular folds move freely in and out of the joint during movements. These features are demonstrated in anatomic studies using transverse sections and radiologic studies using computed tomography. In about 4% of lumbar spines examined, the intraarticular fat pads are enlarged and extend from the joint recess(es) into the middle third of one or more facet joints. The fat pads can be identified in CT scans by their radiolucency and distinguished from vacuum phenomenon by measuring their attenuation values. The cause of the intra-articular enlargement of the fat pads is unknown, but it is suggested that their extension into the middle third of the joint may be secondary to degenerative change in the motion segment with capsular laxity in the affected joint.

    Full Text Available Plaque induced gingival enlargement is most commonly seen and when encountered simultaneously with erosive lichen planus poses a challenge to the treating dentist. Prognosis of one condition may influence the prognosis of another condition. The presented case highlights the significance of proper diagnosis and the management of simultaneously occurring gingival lesions. A 49-year-old hypertensive female presented with painful enlarged bleeding and suppurating gums with burning sensation on eating food along with long-term usage of antihypertensive drug amlodipine known for its gingival enlargement effect. All these multiple factors led to diagnostic dilemma. Effective management of the gingival enlargement was done by using electrocautery to rehabilitate the functions and esthetics of the patient. Gingival condition was also complicated by the presence of coexisting lichen planus which was predominantly erosive for which topical corticosteroid, antifungal, and antimicrobial agents were prescribed. Eight-month follow-up did not show recurrence of gingival enlargement. Electrocautery is an effective tool for the gingivectomy in severe inflammatory type of gingival enlargement because of rapid postoperative hemostasis. For the management of erosive lichen planus, long-term use of topical corticosteroids is an effective approach. Maintenance of oral hygiene and regular follow-ups are essential for these conditions.

    Full Text Available For half a century, European Union-(EU has pursued ever-deeper integration while taking in new members. It’s marked as an important step in relationship deepening between EU and Western Balkans-(WBs where Albania is part of. In 2003, EU declared that the future of WBs is within EU. Initially it adopted a generous strategy that linked the timetable for accession to the pace of reform in WBs. The declaration contained a conditional promise; EU would consider WBs for membership only if they reached EU standards. The EU was motivated by usual economic considerations connected to enlargement and a desire to increase regional stability. The enlargement process regarding Albania will bring several reforms on different fields. Our country will benefit from a share of multibeneficiary funds for competitiveness, SMEs, energy efficiency and banking sector regulation. This presentation handles out these main issues: EU policy and the enlargement process regarding Albania inspecting the way and progress done up to now by our country, the main features of our national EUcoordination system, concluding in a SWOT Analysis of EU-coordination system in Albania. Eventually, I believe that Albania being part of WBs is at one time an opportunity and a challenge for the future of EU.

    Tumescent power liposuction is widely used on various parts of the body for minimal-access lipectomy. The undesired fat deposits are injected with tumescence fluid containing saline, epinephrine, bicarbonate and lidocaine; the latter is used as the only source of pain control. The fat is then removed using vibrating microcannulas. To evaluate the value of tumescent power liposuction in the treatment of the enlarged male breast. 38 male patients aged 23-64 years (mean age 39.8 +/- 9.7 years) with enlarged breasts were enrolled in the study. In 32 patients, breasts were enlarged due to fat tissue, and the ductal glands were not palpable (pseudogynecomastia). In 6 patients, the ductal glands were enlarged (gynecomastia). All patients were treated with tumescent liposuction over a 2-year period using a single entry site from the axillary fossa. Both fat as well as ductal and stromal tissue were removed by microcannulas. None of the patients had early postoperative complications of infection, hematoma or seroma. There were no treatment-induced asymmetries, contour deformities or irregularities. No open excision or skin reduction procedures were required. Tumescent liposuction using a single entry site in the axillary fossa is a minimally invasive technique to treat enlarged male breasts. Both fat (pseudogynecomastia in adipose patients) as well as ductal and stromal tissue (in gynecomastia) can be removed with tumescent liposuction, resulting in a high level of patient satisfaction.

    The association between intracranial internal carotid artery (IICA) calcification and lacunes, white matter hyperintensity (WMH), and cerebral microbleeds (CMBs) has been well researched. However, enlarged cerebral perivascular space (PVS) has not yet been reported to correlate with intracranial internal carotid artery calcification. Therefore, the primary aim of this study was to investigate the relationship between IICA calcification and enlarged PVS. A total of 189 patients with ischemic stroke in the middle cerebral artery territory who presented within 7 days of ictus from 2012 to 2015 were enrolled respectively. All patients were required to have undergone head computed tomography, magnetic resonance imaging, susceptibility-weighted magnetic resonance imaging, magnetic resonance angiography, or computed tomography angiography. Clinical characteristics were recorded. IICA calcification and enlarged PVS were semi-quantitatively evaluated, and the presence of lacunes, WMH, and CMBs was recorded. Of the 189 patients, 63.5% were male. Mean age of the patients was 68.6 ± 12.2 years. There were 104 patients with IICA calcification. Age, diabetes mellitus, lacunes, and white matter hyperintensity were significantly associated with IICA calcification (P < 0.05). Multivariate logistic regression analysis showed that age, diabetes mellitus, and lacunes were independent predictors of IICA calcification (P < 0.05). A lower risk of IICA calcification was found in patients with a higher enlarged PVS score (P = 0.004). Higher enlarged PVS scores were associated with a lesser degree of IICA calcification. There appears to be a relationship between reduced risk of IICA calcification and enlarged PVS. (orig.)

    We examined the nasopharynx and brain in 17 patients with anorexia nervosa by CT and compared the findings with those of 44 normal subjects and of 5 patients of the same age with marked emaciation caused by various psychiatric disorders. An enlarged nasopharyngeal space with a flattened posterior wall and enlarged lateral pharyngeal recesses were demonstrated in all patients with anorexia nervosa whose weight was lowest at the time of the CT examination, and these CT features regressed or became normal quickly after they had gained some weight. This characteristic enlargement of the nasopharynx and lateral pharyngeal recesses was observed neither in the markedly emaciated patients (2 with schizophrenia, 1 with major depression, 1 with stupor and the other with an extremely unbalanced diet) nor in 44 normal subjects without emaciation. These features were therefore thought to be characteristic and of diagnostic significance. (orig.). With 5 figs., 3 tabs.

    Full Text Available Sarcoidosis is classified as an acquired systemic granulomatous disease. Because of the fact that sarcoidosis affects multiple tissues and organs, it is characterized by many potential signs and symptoms, as well as by the presence of non-caseating granulomas in the organs involved. Although oral sarcoidosis is relatively rare, it may however, present in the oral cavity. This report presents a rare case of sarcoidosis with the initial presenting symptom as severe generalized gingival enlargement. The gingival enlargement was treated by gingivectomy. After histopathological examination of gingival biopsy and certain special investigations, a diagnosis of sarcoidosis was made.

  19. Aortic Root Enlargement or Sutureless Valve Implantation?

    Full Text Available Aortic valve replacement (AVR in patients with a small aortic annulus is a challenging issue. The importance of prosthesis–patient mismatch (PPM post aortic valve replacement (AVR is controversial but has to be avoided. Many studies support the fact that PPM has a negative impact on short and long term survival. In order to avoid PPM, aortic root enlargement may be performed. Alternatively and keeping in mind that often some comorbidities are present in old patients with small aortic root, the Perceval S suturelles valve implantation could be a perfect solution. The Perceval sutureless bioprosthesis provides reasonable hemodynamic performance avoiding the PPM and providing the maximum of aortic orifice area. We would like to see in the near future the role of the aortic root enlargement techniques in the era of surgical implantation of the sutureless valve (SAVR and the transcatheter valve implantation (TAVI.

    Multivariate analysis of enlarged cerebral ventricle on CT was undertaken to study the characteristics of ventricular morphology. Several ventricular segments of enlarged ventricle, defined on the basis of the study of normal group, were linearly measured on CT image. Then the discriminant analysis with the increase and decrease of variable was applied. The following are the results obtained. The error ratio of discrimination between pressure hydrocephalus and cerebral atrophy was 8.4 %, and between obstructive hydrocephalus and communicating hydrocephalus was 11.3 %. Ventricular segments were divided into three groups according to their character of enlargement: (1) the temporal horn and trigone are large in pressure hydrocephalus; (2) the hypothalamic segment of the third ventricle and the body of lateral ventricle are larger in obstructive hydrocephalus than in communicating hydrocephalus; (3) the anterior horn, cellae mediae at the level of the head of caudate nuclei and thalamic segment of the third ventricle are relatively large in cerebral atrophy and communicating hydrocephalus. The hypothalamic segment of the third ventricle assumes a round or oval shape in pressure hydrocephalus but a rectangular or teardrop shape in cerebral atrophy. These findings are contributory to pathological evaluation of ventricular enlargement. (author)

    The monthly global 2°×2° Extended Reconstructed Sea Surface Temperature (ERSST) has been revised and updated from version 4 to version 5. This update incorporates a new release of ICOADS R3.0, a decade of near-surface data from Argo floats, and a new estimate of centennial sea-ice from HadISST2. A number of choices in aspects of quality control, bias adjustment and interpolation have been substantively revised. The resulting ERSST estimates have more realistic spatio-temporal variations, better representation of high latitude SSTs, and ship SST biases are now calculated relative to more accurate buoy measurements, while the global long-term trend remains about the same. Progressive experiments have been undertaken to highlight the effects of each change in data source and analysis technique upon the final product. The reconstructed SST is systematically decreased by 0.077°C, as the reference data source is switched from ship SST in v4 to modern buoy SST in v5. Furthermore, high latitude SSTs are decreased by 0.1°-0.2°C by using sea-ice concentration from HadISST2 over HadISST1. Changes arising from remaining innovations are mostly important at small space and time scales, primarily having an impact where and when input observations are sparse. Cross-validations and verifications with independent modern observations show that the updates incorporated in ERSSTv5 have improved the representation of spatial variability over the global oceans, the magnitude of El Niño and La Niña events, and the decadal nature of SST changes over 1930s-40s when observation instruments changed rapidly. Both long (1900-2015) and short (2000-2015) term SST trends in ERSSTv5 remain significant as in ERSSTv4.

    Objective: To investigate the relationship between enlargement of pituitary in postpartum females and the clinical biochemistry. Methods: In total 6 postpartum women were studied by MRI of pituitary and clinical biochemistry assessment, the data was collected especially in puerperium period. Results: Enlargement of pituitary gland was most remarkable in the first week of puerperium period, while endocrine changes including HCG, Progesterone, E 2 also reached considerable high peak in the same time especially the first and second day after labor. Prolactin also increased. βHCG, Progesterone, and E 2 rapidly decreased after the first week of puerperium period and the size of pituitary gland recovered to normal size. Conclusion: Postpartum enlargement of pituitary gland is physiological and related with internal environment change in gravitation, which is not to be misdiagnosed as a lesion

    We demonstrate the multislice computed tomography (MSCT) findings of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA)-proven hilar and mediastinal lymph node enlargement with signs of anthracosis. 53 enlarged lymph nodes in 39 patients (28 male, 11 female) with EBUS-TBNA-confirmed anthracosis were analyzed retrospectively. The mean short axis diameter of the enlarged lymph nodes with signs of anthracosis was 13.7 mm. Lymph nodes most often showed an oval shape (84%) and were well defined in 66% of cases. Lymph node confluence was observed in 32% of cases. Calcifications were documented in 24.5% of cases. Contrast enhancement and fatty involution were seen seldom (3.8%). Lymph node necrosis was not seen. Lymph node anthracosis may be found most often in enlarged, well defined lymph nodes with an oval shape, frequently associated with confluence and calcifications.

  8. Supersymmetric versions of the Fokas–Gel’fand formula for immersion

    International Nuclear Information System (INIS)

    Bertrand, S; Grundland, A M

    2016-01-01

    In this paper, we construct and investigate two supersymmetric versions of the Fokas–Gel’fand formula for the immersion of 2D surfaces associated with a supersymmetric integrable system. The first version involves an infinitesimal deformation of the zero-curvature condition and the linear spectral problem associated with this system. This deformation leads the surfaces to be represented in terms of a bosonic supermatrix immersed in a Lie superalgebra. The second supersymmetric version is obtained by using a fermionic parameter deformation to construct surfaces expressed in terms of a fermionic supermatrix immersed in a Lie superalgebra. For both extensions, we provide a geometrical characterization of deformed surfaces using the super Killing form as an inner product and a super moving frame formalism. The theoretical results are applied to the supersymmetric sine-Gordon equation in order to construct super soliton surfaces associated with five different symmetries. We find integrated forms of these surfaces which represent constant Gaussian curvature surfaces and nonlinear Weingarten-type surfaces. (paper)

    To determine the frequency of adrenal enlargement of participants in a CT-screening program for lung cancer and demonstrate the progression during follow-up, separately for baseline and annual repeat rounds. HIPAA-compliant informed consent was obtained in 4,776 participants. The adrenal gland was defined as enlarged if it measured ≥6 mm at its largest diameter. Logistic regression analyses were performed. At baseline, 202 (4 %) of 4,776 participants had adrenal enlargement. Significant factors were age (OR = 1.4, 95 % CI: 1.2-1.7) and current smoker (OR = 1.8, 95 % CI: 1.3-2.4). Follow-up 7-18 months after baseline for 133 cases with adrenal enlargement <40 mm showed it decreased or was stable in 85 (64 %), and increased by <10 mm in 48 (36 %). Five (0.04 %) cases of adrenal enlargement were newly identified, none increased beyond 40 mm on follow-up. Adrenal enlargement was a significant predictor of a subsequent diagnosis of lung cancer (OR = 2.0, 95 % CI: 1.2-3.4). Participants with adrenal enlargement <40 mm identified at baseline and on repeat screening could be reasonably assessed on subsequent annual screening. Adrenal enlargement increased with increasing pack-years of smoking. Adrenal enlargement was an independent predictor of a subsequent diagnosis of lung cancer. (orig.)

    The increase in size of lymph node on CT scan is the single most important finding of lymphadenopathy. The purpose of this study was to evaluate the size of mediastinal lymph nodes in patients with idiopathic pulmonary fibrosis with no evidence of malignancy or current infection. CT scans of 70 patients (16 with conventional CT and 54 with high-resolution CT) were assessed for lymph node size and location. The duration of symptoms, and the extent and pattern of the parenchymal lung disease on CT scans were correlated with lymph node enlargement. In 54 of 70 patients, more than one lymph nodes were large than 1-1.5 cm. The prevalence of node enlargement increased significant with a longer duration of symptom (p=0.001), large extent of the disease (p=0.043), and with a greater proportion of honeycomb pattern (p=0.033). Right paratracheal, subcarinal, right tracheobronchial, and paraesophageal nodes were the most common sites of node enlargement. In conclusion, mediastinal lymph node enlargement is common in patients with idiopathic pulmonary fibrosis and is more frequently seen in patients with a longer duration of clinical symptoms, greater extent of the disease, and with a larger proportion of honeycomb pattern

    Fifty-one patients were divided into two groups: 20 patients with proven rheumatic mitral valve disease (RMVD) and 31 patients with left atrial enlargement (LAE) of a nonrheumatic etiology. The latter group included patients with ischemic papillary muscle dysfunction, mitral valve prolapse, and congestive cardiomyopathy. Radiographic studies showed that enlargement of the left atrial appendage (LAAE) was present in 18 of 20 rheumatics but in only one of 31 nonrheumatics. There was no direct relationship between enlargement of the LAA and radiographic or echocardiographic left atrial size, degree of pulmonary venous hypertension (PVH), or presence of atrial fibrillation. It is postulated that rheumatic influammation of the LAA allows it to dilate out of proportion to the body of the left atrium. In the adult patient with radiographic findings of PVH, LAAE is a valuable and specific radiographic sign of rheumatic mitral valve disease

    The objective of this study was to compare the seizure characteristics and treatment outcomes in patient groups with temporal lobe epilepsy (TLE) identified with isolated amygdala enlargement (AE) on magnetic resonance imaging studies. PubMed, Embase, and the Cochrane Library were searched for relevant studies using the keywords 'amygdala enlargement', 'epilepsy', and 'seizures' in April 2015. Human studies, written in English, that investigated cohorts of patients with TLE and AE were included. Of 204 abstracts initially identified using the search strategy, 14 studies met the inclusion criteria (11 epilepsy studies and 3 psychiatry studies). Ultimately, 8 full studies on AE and TLE involving 107 unique patients were analyzed. Gender distribution consisted of 50 males and 57 females. Right amygdala enlargement was seen in 39 patients, left enlargement in 58 patients, and bilateral enlargement in 7 patients. Surgical resection was performed in 28 patients, with the most common finding being dysplasia/hamartoma or focal cortical dysplasia. Most studies involved small samples of less than 12 patients. There was a wide discrepancy in the methods used to measure amygdala volume, in both patients and controls, hindering comparisons. Most TLE with AE studies observed a later age of seizure onset (mean: 32.2years) compared with studies involving TLE with HS (mean of mid- to late childhood). A higher frequency of complex partial seizures compared with that of convulsive seizures is seen in patients with AE (67-100% vs. 26-47%), and they have an excellent response to antiepileptic drugs (81.8%-100% of seizure-free patients). All studies that included controls also found a significant difference in frequency of seizure types between their cases and controls. Reliable assessment of amygdala volume remains a critical issue hindering better understanding of the clinical management and research of this focal epilepsy syndrome. Within these limitations, the literature suggests

    PHACES syndrome is a complex of morphologic abnormalities of unknown cause and includes posterior fossa abnormalities; head and neck infantile hemangiomas; arterial, cardiac, and eye anomalies; and sternal or abdominal wall defects. Accurate identification of the syndrome is important for optimal treatment. The purpose of this study was to investigate the incidence of asymmetric Meckel cave enlargement, a potential novel imaging marker, in a population of patients referred for evaluation of possible PHACES syndrome. Eighty-five patients referred for neuroimaging evaluation of possible PHACES syndrome were identified and stratified on the basis of their ultimate clinical PHACES diagnosis categorization into PHACES, possible PHACES, or not PHACES. MR imaging studies were subsequently reviewed for the presence or absence of unilateral Meckel cave enlargement, with the reviewer blinded to the ultimate PHACES syndrome categorization. Twenty-five of 85 patients (29%) were ultimately categorized as having PHACES or possible PHACES according to consensus guidelines. Asymmetric Meckel cave enlargement was present in 76% (19/25) of these patients and in 82% (19/23) of only those patients with definite PHACES. This finding was present in none of the 60 patients determined not to have PHACES syndrome. In 7/19 patients (37%) with this finding, subtle MR imaging abnormalities consistent with PHACES were missed on the initial MR imaging interpretation. Asymmetric Meckel cave enlargement was a common feature of patients with PHACES in our cohort and may serve as a novel imaging marker. Increased awareness of this imaging feature has the potential to increase the diagnostic accuracy of PHACES. © 2017 by American Journal of Neuroradiology.

    The purpose of this study is to describe a new method to quickly estimate left atrial enlargement (LAE) on Computed Tomography. Left atrial (LA) volume was assessed with a 3D-threshold Hounsfield unit detection technique, including left atrial appendage and excluding pulmonary venous confluence, in 201 patients with ECG-gated 128-slice dual-source CT and indexed to body surface area. LA and vertebral axial diameter and area were measured at the bottom level of the right inferior pulmonary vein ostium. Ratio of LA diameter and surface on vertebra (LAVD and LAVA) were compared to LA volume. In accordance with the literature, a cutoff value of 78 ml/m 2 was chosen for maximal normal LA volume. 18% of LA was enlarged. The best cutoff values for LAE assessment were 2.5 for LAVD (AUC: 0.65; 95% CI: 0.58-0.73; sensitivity: 57%; specificity: 71%), and 3 for LAVA (AUC: 0.78; 95% CI: 0.72-0.84; sensitivity: 67%; specificity: 79%), with higher accuracy for LAVA (P=0.015). Inter-observer and intra-observer variability were either good or excellent for LAVD and LAVA (respective intraclass coefficients: 0.792 and 0.910; 0.912 and 0.937). A left atrium area superior to three times the vertebral area indicates LAE with high specificity. (orig.)

    An enlarged cylindrical-anode-layer Hall plasma accelerator with an outlet diameter of 150 mm is experimentally demonstrated to produce a concentrated ion beam, especially at a high discharge voltage, with a high current utilization efficiency of up to {approx}0.9. Numerical investigation based on the three-dimensional particle-in-cell method is performed to study the ion dynamics and elucidate the origin of the ion beam characteristics. The simulation results reveal that the equipotential lines play an important role in the surface near the anode emitting the ions. The ion emitting surface is determined by the magnetic field lines near the anode and the magnetic mirror contributes to the concentrated beam significantly. The high current utilization efficiency results from the appropriate obliquity of the magnetic mirror.

  2. The paradox of EU enlargement and member states' policies: Dilemmas and challenges: The case of Portugal

    Directory of Open Access Journals (Sweden)

    Neves Santos Miguel

    2016-01-01

    Full Text Available The paper addresses the issue of EU enlargement with its dual nature: of an intra-EU process, related to the consolidation of a democratic-peace based on collective security, and an external process, involving EU foreign policy and impact on relations with other major global players. Although enlargement is a multidimensional process that combines different perspectives - candidate countries' enlargement politics, member states' politics/policy, EU enlargement politics and external global impact - the paper focuses on Member States policies towards enlargement by looking at the case of Portugal, in particular in relation with the Big Bang Eastern enlargement, and aims at explaining the paradox of Portugal's strong political support to enlargement while it was one of the main potential losers in terms of economic interests. A 'foreign policy analysis' framework is adopted in order to understand the process of decision-making and the interaction between the domestic and the EU levels. The argument put forward is that an exclusive constructivist approach does not provide a satisfactory explanation, as there was also rationalist-interest logic at play. The Portuguese policy towards enlargement was determined not only by the 'solidaritysimilarity' logic, dominant in the formal political discourse but also by the consideration of long-term interests in the EU related to the preservation of the strategic alliance with Germany. The overall systemic impact of enlargement tends to weaken the EU as it presents a major paradox functioning as a double-edged sword. While it has a positive impact by contributing to the enhancement of the EU international profile as it grows in size raising expectations about its potential global role, it also leads to greater heterogeneity, undermining the EU cohesion and its ability to act together with a single voice becoming a robust global player, thus frustrating the expectations raised in the first place.

    Childhood asymmetrical labium majus enlargement (CALME) has been described sparsely in recent surgery, pathology, pediatric and gynecology literature; however, no comprehensive description from a radiology perspective has been developed. The purpose of this case series is to describe the imaging findings of CALME and to review the current understanding of this recently described clinical entity with regard to clinical presentation, pathophysiology, differential diagnosis and treatment options. This is a retrospective analysis of 3 girls, ages 5-7 years, who presented for imaging evaluation with subsequent pathologically proven CALME. Each child's clinical history, length of symptoms, imaging appearance and pathological findings were reviewed. All three girls presented with unilateral enlargement of the labium majus (two right-side, one left-side) with no history of trauma or other inciting cause. Two girls had painless labial enlargement that was recognized for weeks, and one had similar symptoms for 1 year prior to presentation. One girl was evaluated initially with sonography, and all three children underwent MR imaging. Sonographic evaluation showed asymmetrical labial enlargement without a definable mass. In each girl, the MR imaging findings were characterized by relatively ill-defined T1-weighted hypointense signal, T2-weighted hypo- to isointense signal with interspersed hyperintense septae, and heterogeneous patchy and feathery strands of enhancement on post-contrast imaging. Biopsy from each child showed benign fibrous tissue with intervening mature fibroadipose tissue, vessels and nerves without findings of inflammation or neoplasia. The MR imaging appearance of CALME is consistent. Recognition and appreciation of this unique pediatric entity by the radiologist may be essential for appropriate diagnosis and can help to guide therapy. Current preferred treatment approach is conservative. (orig.)

    This code was developed to aid design engineers in the selection and evaluation of aerodynamically efficient wing-canard and wing-horizontal-tail configurations that may employ simple hinged-flap systems. Rapid estimates of the longitudinal aerodynamic characteristics of conceptual airplane lifting surface arrangements are provided. The method is particularly well suited to configurations which, because of high speed flight requirements, must employ thin wings with highly swept leading edges. The code is applicable to wings with either sharp or rounded leading edges. The code provides theoretical pressure distributions over the wing, the canard or horizontal tail, and the deflected flap surfaces as well as estimates of the wing lift, drag, and pitching moments which account for attainable leading edge thrust and leading edge separation vortex forces. The wing planform information is specified by a series of leading edge and trailing edge breakpoints for a right hand wing panel. Up to 21 pairs of coordinates may be used to describe both the leading edge and the trailing edge. The code has been written to accommodate 2000 right hand panel elements, but can easily be modified to accommodate a larger or smaller number of elements depending on the capacity of the target computer platform. The code provides solutions for wing surfaces composed of all possible combinations of leading edge and trailing edge flap settings provided by the original deflection multipliers and by the flap deflection multipliers. Up to 25 pairs of leading edge and trailing edge flap deflection schedules may thus be treated simultaneously. The code also provides for an improved accounting of hinge-line singularities in determination of wing forces and moments. To determine lifting surface perturbation velocity distributions, the code provides for a maximum of 70 iterations. The program is constructed so that successive runs may be made with a given code entry. To make additional runs, it is

From January 2015 to May 2016, 42 subjects who sought aesthetic treatment underwent intradermal injection of LMW-HA to improve enlarged facial pores. For each treatment, 2.5 mL (25 mg) of LMW-HA was injected into the skin of the full face. The treatment was repeated 2-5 times with an interval of 1 to 1.5 months between consecutive treatments. The postoperative follow-up period was 1 to 6 months. Statistical analysis was used to compare the degree of enlargement of facial pores before and after injection. The clinical efficacy and adverse effects were recorded. The enlarged facial pores before and after treatment were categorized and subjected to the Wilcoxon matched-pairs signed-rank test. The difference was statistically significant (Pinjection sites in the subjects who sought aesthetic treatment. The overall satisfaction rate was 92.8%. Intradermal injection of LMW-HA can significantly improve skin texture, reduce pore size, and enhance skin radiance. The injection technique was simple, safe, and effective and could easily be extended to clinical practice. © 2017 Wiley Periodicals, Inc.

    Objective: To discuss the value of enlargement of geniculate fossa of facial nerve canal in the diagnosis of facial nerve canal fracture. Methods: Thirty patients with facial nerve canal fracture underwent axial and coronal CT scan. The correlation between the fracture and the enlargement of geniculate fossa of facial nerve canal was analyzed. The ability of showing the fracture and enlargement of geniculate fossa of facial nerve canal in axial and coronal imaging were compared. Results: Fracture of geniculate fossa of facial nerve canal was found in the operation in 30 patients, while the fracture was detected in CT in 18 patients. Enlargement of geniculate ganglion of facial nerve was detected in 30 patients in the operation, while the enlargement of fossa was found in CT in 28 cases. Enlargement and fracture of geniculate fossa of facial nerve canal were both detected in CT images in 18 patients. Only the enlargement of geniculate fossa of facial nerve canal was shown in 12 patients in CT. Conclusion: Enlargement of geniculate fossa of facial nerve canal was a useful finding in the diagnosis of fracture of geniculate fossa in patients with facial paralysis, even no fracture line was shown on CT images.

    This randomized controlled trial was conducted to evaluate the effect of foraminal enlargement during chemomechanical root canal preparation on postoperative pain. Seventy mandibular first molars with asymptomatic pulp necrosis and chronic apical periodontitis were randomized into two groups - foraminal enlargement (FE) and conventional nonforaminal enlargement (NFE). Canals were prepared according to the respective protocols, and the teeth were restored temporarily. Postoperatively, the patients were prescribed ibuprofen 400 mg, to be taken if required. Pain experience and analgesic intake were recorded for 7 days following chemomechanical preparation. The data were analysed using Mann-Whitney U-test and chi-square tests. Pain experience was higher with foraminal enlargement than when using a conventional technique. A significant difference was observed in postoperative pain during the first 4 days and the sixth day (P  0.05). Enlargement of the apical foramen during root canal treatment increased the incidence and intensity of postoperative pain. © 2015 International Endodontic Journal.

    The AIRS Science Team Version-6 data set is a valuable resource for meteorological studies. Quality Controlled earth's surface skin temperatures are produced on a 45 km x 45 km spatial scale under most cloud cover conditions. The same retrieval algorithm is used for all surface types under all conditions. This study used eleven years of AIRS monthly mean surface skin temperature and cloud cover products to show that land surface skin temperatures have decreased significantly in some areas and increased significantly in other areas over the period September 2002 through August 2013. These changes occurred primarily at 1:30 PM but not at 1:30 AM. Cooling land areas contained corresponding increases in cloud cover over this time period, with the reverse being true for warming land areas. The cloud cover anomaly patterns for a given month are affected significantly by El Nino/La Nina activity, and anomalies in cloud cover are a driving force behind anomalies in land surface skin temperature.

    A case of the persistence of the primitive hypoglossal artery is reported, with a roentgenographic demonstration of the enlarged hypoglossal canal. A 63-year-old man was admitted to this hospital as a result of a malfunction of the ventriculo-peritoneal shunt. At the age of 51, the patient had been operated on in this hospital for an aneurysm of the right middle cerebral artery; at that time, the right primitive hypoglossal artery was observed on right carotid angiograms. On the day following admission, bilateral retrograde vertebral angiography was performed and the right persistent primitive hypoglossal artery was recognized again. Stenvers views of the skull demonstrated an enlargement of the hypoglossal canal, with a smooth sclerotic rim. High-resolution computed tomography with a contrast infusion delineated the right primitive hypoglossal artery through the enlarged hypoglossal canal. The diameter of the enlarged right hypoglossal canal and that of the left one were found to be 8 mm and 4 mm respectively on the CT. When an enlargement of the hypoglossal canal with a sclerotic rim is observed, the persistence of the primitive hypoglossal artery should be considered in the differential diagnosis. (author)

    Causes of unilateral hydrocephalus resulting from an obstruction at the Monro foramen include foraminal atresia, tumors, gliosis, contralateral shunting, and infectious and inflammatory conditions. However, few reports in the literature cite vascular lesions as the cause of the obstruction. To their knowledge, the authors present the first report of unilateral hydrocephalus occurring due to an abnormally enlarged thalamostriate vein independent of an arteriovenous malformation or developmental venous angioma. The condition was treated successfully by endoscopic septum pellucidum fenestration. A 28-year-old man was referred for evaluation due to a 10-year history of chronic headaches that worsened in severity over the past year. A CT scan of the head revealed unilateral right ventricular dilation. Cranial MR imaging with and without contrast administration showed a dilated right thalamostriate-internal vein complex without any evidence of associated arteriovenous malformation or venous angioma. Endoscopic exploration of the right lateral ventricle showed an enlarged subependymal thalamostriate vein obstructing the Monro foramen. An endoscopic fenestration of the septum pellucidum was performed, resulting in alleviation of the patient's symptoms. Abnormally enlarged venous structures may cause obstructive unilateral hydrocephalus and can be a rare cause of chronic, intermittent headaches in adults. Endoscopic fenestration of the septum pellucidum is an effective treatment.

    Idiopathic gingival enlargement is a rare condition characterized by massive enlargement of the gingiva. It may be associated with other diseases/conditions characterizing a syndrome, but rarely associated with periodontitis. This case report describes an unusual clinical form of gingival enlargement associated with chronic periodontitis. Clinical examination revealed diffuse gingival enlargement. The lesion was asymptomatic, firm, and pinkish red. Generalized periodontal pockets were observed. Radiographic evaluation revealed generalized severe alveolar bone loss. Histopathological investigations revealed atrophic epithelium with dense fibrocollagenous tissue. Lesions healed successfully following extraction and surgical excision, and no recurrence was observed after 1 year follow-up but recurrence was observed at 3 and 5-years follow-up. Successful treatment of idiopathic gingival enlargement depends on proper identification of etiologic factors and improving esthetics and function through surgical excision of the over growth. However, there may be recurrence.

    By considering the nonrelativistic limit of de Sitter geometry one obtains the nonrelativistic space-time with a cosmological constant and Newton Hooke (NH) symmetries. We show that the NH symmetry algebra can be enlarged by the addition of the constant acceleration generators and endowed with central extensions (one in any dimension (D) and three in D=(2+1)). We present a classical Lagrangian and Hamiltonian framework for constructing models quasi-invariant under enlarged NH symmetries that depend on three parameters described by three nonvanishing central charges. The Hamiltonian dynamics then splits into external and internal sectors with new noncommutative structures of external and internal phase spaces. We show that in the limit of vanishing cosmological constant the system reduces to the one, which possesses acceleration-enlarged Galilean symmetries.

    In the construction of reactors or pressure vessels for oil chemical plants and nuclear power stations, mono block open-die forging rings are often utilized. Generally, a large forged ring is manufactured by means of enlarging forging with reductions of the wall thickness. During the enlarging process the circular ring is often distorted and becomes an ellipse in shape. However the shape control of the ring is a complicated work. This phenomenon makes the matter still worse in forging of larger rings. In order to make precision forging of large rings, we have developed the forging method using a v-shape anvil. The v-shape anvil is geometrically adjusted to fit the distorted ring in the final circle and reform automatically the shape of the ring during enlarging forging. This paper has analyzed the reforming process of distorted ring by computer program based on F.E.M. and examined the effect on the precision of ring forging. (author)

  2. A Rare Case Report of Amlodipine-Induced Gingival Enlargement and Review of Its Pathogenesis

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available Gingival enlargement is a common clinical feature of gingival and periodontal diseases. It is an unwanted side effect of certain systemic drugs given for nondental treatment. It is being reported with three main groups of drugs like calcium channel blockers (CCBs, immunosuppressants, and anticonvulsants. Among calcium channel blockers, nifedipine causes gingival hyperplasia in about 10% of patients, whereas the incidence of amlodipine-, a third generation calcium channel blocker, induced gingival hyperplasia is very limited. There are very few reports of amlodipine-induced gingival enlargement at a dose of 5 mg. We report a case of amlodipine-induced gingival enlargement in a 45-year-old hypertensive patient taking amlodipine at a dose of 5 mg.

  3. Long term follow up of idiopathic gingival enlargement associated with chronic periodontitis: A case report and review

    2013-01-01

    Full Text Available Background: Idiopathic gingival enlargement is a rare condition characterized by massive enlargement of the gingiva. It may be associated with other diseases/conditions characterizing a syndrome, but rarely associated with periodontitis. Case Description: This case report describes an unusual clinical form of gingival enlargement associated with chronic periodontitis. Clinical examination revealed diffuse gingival enlargement. The lesion was asymptomatic, firm, and pinkish red. Generalized periodontal pockets were observed. Radiographic evaluation revealed generalized severe alveolar bone loss. Histopathological investigations revealed atrophic epithelium with dense fibrocollagenous tissue. Lesions healed successfully following extraction and surgical excision, and no recurrence was observed after 1 year follow-up but recurrence was observed at 3 and 5-years follow-up. Clinical Implications: Successful treatment of idiopathic gingival enlargement depends on proper identification of etiologic factors and improving esthetics and function through surgical excision of the over growth. However, there may be recurrence.

    The aim of this study was to investigate the natural course of enlarged nuchal translucency (NT) and to determine if its disappearance before 14 weeks' gestation is a favorable prognostic sign in relation to fetal karyotype and pregnancy outcome. A total of 147 women with increased NT (> 95th centile) at first measurement were included in this study. A second measurement was performed in all cases, at an interval of at least 2 days. Both measurements were taken between 10 + 3 and 14 + 0 weeks. All women underwent chorionic villus sampling or amniocentesis for subsequent karyotyping. In those women with a normal karyotype, a fetal anomaly scan was performed at 20 weeks' gestation. Pregnancy outcome was recorded in all cases. The finding of persistent or disappearing NT enlargement was analyzed in relation to fetal karyotype and pregnancy outcome. Of the 147 paired measurements, NT remained enlarged at the second measurement in 121 (82%) cases. An abnormal karyotype was found in 35% of these cases. In 26 (18%) fetuses the NT measurement was found to be below the 95th percentile at the second measurement and in only two of them an abnormal karyotype was found (8%). In the 103 chromosomally normal fetuses an adverse outcome (i.e. fetal loss or structural defects) was recorded in 22 fetuses with persistent enlargement (28%) and in four fetuses with disappearing enlargement (17%). Disappearance of an enlarged NT before 14 weeks' gestation is not a rare phenomenon and seems to be a favorable prognostic sign with respect to fetal karyotype. Overall, no significant difference in pregnancy outcome was found between chromosomally normal fetuses with persisting or disappearing NT enlargement. Copyright 2004 ISUOG

    2003-01-01

    A number of clinical studies have demonstrated that enlargement of the lumbar spinal canal is one of the effective surgical procedures for the treatment of the lumbar degenerative spondylolisthesis and provides a good result. In the present study, we have evaluated the long-term outcome of the enlargement of the lumbar canal without fusion in thirty eight patients with lumbar degenerative spondylolisthesis using three-dimensional computed tomography (3D-CT) The improvement rate was excellent in 80% of the patients (mean improvement ratio, 83%) according to the Japanese Orthopedic Association scoring system. We found that the sufficient enlargement of the canal was obtained by the surgery and maintained for a long period of time. The results from 3D-CT suggested that a round shape was maintained in the canal after the surgery because of pressures of the dura mater against to the bony canal. None of patients showed lumbar instability. In conclusion, enlargement of lumbar canal without fusion is useful for the treatment of lumbar degenerative spondylolisthesis, and the enlarged canal has been maintained for a long period of time after the surgery. The results demonstrated the clinical utility of 3D-CT to evaluate the preoperative and postoperative shape of the spine. (author)

    Among the temporal bone abnormalities that can be found in the etiological study of paediatric sensorineural hearing loss (SNHL) by imaging techniques, those related to the internal auditory canal (IAC) are the least frequent. The most prevalent of these abnormalities that is associated with SNHL is stenotic IAC due to its association with cochlear nerve deficiencies. Less frequent and less concomitant with SNHL is the finding of an enlarged IAC (>8mm). Retrospective and descriptive review of clinical associations, imaging, audiological patterns and treatment of 9 children with hearing loss and enlarged IAC in the period 1999 to 2012. Two groups of patients are described. The first, without association with vestibulocochlear dysplasias, consisted of: 2 patients with SNHL without other temporal bone or systemic abnormalities, one with bilateral mixed HL from chromosome 18q deletion, one with a genetic X-linked DFN3 hearing loss, one with unilateral hearing loss in neurofibromatosis type 2 with bilateral acoustic neuroma, and one with unilateral hearing loss with cochlear nerve deficiency. The second group, with association with vestibulocochlear dysplasias, was comprised of: one patient with moderate bilateral mixed hearing loss in branchio-oto-renal syndrome, one with profound unilateral SNHL with recurrent meningitis, and another with profound bilateral SNHL with congenital hypothyroidism. The presence of an enlarged IAC in children can be found in different clinical and audiological settings with relevancies that can range from life-threatening situations, such as recurrent meningitis, to isolated hearing loss with no other associations.

    2004-10-01

    Full Text Available EU Enlargement is a consequence of the success story of the creation of the European Communities, as many applicant countries were attracted to the new legal order based on the rule of law, rather than to an order or disorder based on the rule of politics. As from May 1st 2004, the EU enlargement, unprecedented in its size, marks a historic milestone for the European Union and its Member States, and also for the whole continent. Given this new context, the EU has to find and define new cooperation partnerships with its neighbours. A major partner, not to be neglected in this new policy is by all means Russia. The first Summit between the enlarged EU and Russia held in Moscow on 21 May 2004 was the first high-level meeting of the 25 EU and Russia following the successful conclusion of negotiations between the European Commission and Russia on the extension of the EU-Russia Partnership and Cooperation Agreement (PCA to the ten new EU Member States. The Summit calls for the reinforcement of EU-Russia relations via the creation of Four Common Spaces: a common economic space (with specific reference to environment and energy; a common space of Freedom, Security and Justice; a field of external security; as well as a space of research and education including culture. The next step will be to define shared priorities and concrete measures for each of the Four Common Spaces in a mutually agreed Action Plan.

    Full Text Available Fungi are an emerging source of peptide antibiotics. With the availability of a large number of model fungal genome sequences, we can expect that more and more fungal defensin-like peptides (fDLPs will be discovered by sequence similarity search. Here, we report a total of 69 new fDLPs encoded by 63 genes, in which a group of fDLPs derived from dermatophytes are defined as a new family (fDEF8 according to sequence and phylogenetic analyses. In the oleaginous fungus Mortierella alpine, fDLPs have undergone extensive gene expansion. Our work further enlarges the fungal defensin family and will help characterize new peptide antibiotics with therapeutic potential.

    2017-05-01

    Many forms of malware and security breaches exist today. One type of breach downgrades a cryptographic program by employing a man-in-the-middle attack. In this work, we explore the utilization of hardware events in conjunction with machine learning algorithms to detect which version of OpenSSL is being run during the encryption process. This allows for the immediate detection of any unknown downgrade attacks in real time. Our experimental results indicated this detection method is both feasible and practical. When trained with normal TLS and SSL data, our classifier was able to detect which protocol was being used with 99.995% accuracy. After the scope of the hardware event recording was enlarged, the accuracy diminished greatly, but to 53.244%. Upon removal of TLS 1.1 from the data set, the accuracy returned to 99.905%.

    We carried out a retrospective study on non-neoplastic enlargement of the salivary glands at the Oral Histopathology Diagnostic Center of the Autonomous Metropolitan University at Xochimilco (UAM-Xochimilco) in Mexico during a period of 24 years (1979-2003). From 5,625 biopsies received and analyzed, a total of 461 (8.2%) were non-neoplastic enlargement of the salivary glands; for each case, we registered demographic data as well as clinic characteristics. These lesions were characterized as a heterogeneous group of pathologic entities among which we included local, obstructive, infectious, and immunopathologic lesions. The most frequent lesion was the extravasation cyst in 341 (74%) cases, followed by chronic sialoadenitis and Sjögren's syndrome with 54 (11.7%) and 41 (8.8%) cases, respectively, and at a lesser percentage mucous retention cyst, sialosis, benign lymphoepithelial lesions and those related with sialolytes. Females were affected more frequently; mean age was second to third life decades. These lesions were most frequently localized on inferior labial mucosa.

    Full Text Available Digito-rectal examination (DRE of the prostate provides useful information on the state of prostate growth and on the presence of suspected peripheral nodules. The aim of this study is to describe the clinical and biochemical correlates of finding an enlarged prostate size at DRE in subjects with sexual dysfunction (SD. A consecutive series of 2379 patients was retrospectively studied. The analysis was focused on a subset of subjects (n = 1823; mean age 54.7 ± 11.4 selected for being free from overt prostatic diseases. Several parameters were investigated. After adjusting for confounders, the presence of an enlarged prostate size at DRE was associated with a higher risk of metabolic syndrome (HR = 1.346 (1.129-1.759; P = 0.030, type 2 diabetes mellitus (HR = 1.489 (1.120-1.980; P = 0.006, increased LDL cholesterol (>100 mg dl−1 ; HR = 1.354 (1.018-1.801; P = 0.037 and increased mean blood pressure (BP values (HR = 1.017 (1.007-1.027 for each mmHg increment; P = 0.001. Accordingly, enlarged prostate size was also associated with a higher risk of arteriogenic erectile dysfunction (ED, as well as with other andrological conditions, such as varicocele and premature ejaculation (PE. PSA levels were significantly higher in subjects with enlarged prostate size when compared to the rest of the sample (HR = 3.318 (2.304; 4.799 for each log unit increment in PSA levels; P < 0.0001. Arteriogenic ED, according to different criteria, was also associated with increased PSA levels. In conclusion, our data support the need to examine prostate size either by clinical (DRE or biochemical (PSA inspection in subjects with SD, in order to have insights into the nature of the SD and the metabolic and cardiovascular (CV background of the patient.

    PURPOSE: Painless parotid enlargement has been recently reported as a sign of AIDS, but little is known of the imaging characteristics of parotid involvement in affected children. The aim of this paper is to use US, CT and MR imaging to determine the anatomic changes of the parotid; study their possible association with pulmonary lymphoid hyperplasia (PLH); and define the immunologic parameters and clinical course. Eighteen children were evaluated clinically, radiologically, and immunologically. All patients underwent US of the parotids and chest radiography; some children had CT of the chest and MR imaging of the parotids

  15. Characteristics and significance of D-tagatose-induced liver enlargement in rats: An interpretative review.

    Science.gov (United States)

    Bär, A

    1999-04-01

    This review addresses the issue of asymptomatic liver enlargement in rats. It was necessitated by the observation of significantly increased liver weights in rats fed diets with 10 to 20% D-tagatose, a potential new bulk sweetener, for between 28 and 90 days. Increases of liver size without accompanying histopathological changes or impairment of organ function have been observed in rats in response to the ingestion of various xenobiotic compounds (including some food additives), changes of dietary composition (e.g. , high doses of fructose and sucrose), metabolic aberrations (e.g., diabetes), as well as normal pregnancy and lactation. The underlying mechanism(s) are not yet understood in detail but peroxisome proliferation, microsomal enzyme induction, increased storage of glycogen or lipids, and hyperfunction due to an excessive workload are well-established causes of hepatomegaly in rats. In D-tagatose- and fructose-fed rats, a treatment-related increase of hepatic glycogen storage was identified as a likely cause of the liver enlargement. Dietary levels of 5% and about 15-20% were determined as no-effect levels (NOEL) for D-tagatose- and fructose-induced liver enlargement, respectively. At doses above the NOEL, D-tagatose is about four times more efficient than fructose in inducing liver enlargement. On the other hand, the estimated intake of D-tagatose from its intended uses in food is about four times lower than the actual fructose intake. Consequently, a similar safety margin would apply for both sugars. Considering the similarity of the liver effects in rats of fructose, a safe food ingredient, and D-tagatose, the absence of histopathological changes in rats fed a diet with 20% D-tagatose for 90 days, and the absence of adverse long-term consequences of glycogen-induced liver enlargement in rats, it is concluded that the observed liver enlargement in D-tagatose-fed rats has no relevance for the assessment of human safety of this substance.

    Full Text Available Calf enlargement following sciatica is a rare condition. It is reported the case of a 28-year-old woman who complained of repeated episodes of lower back pain radiating into the left buttock and foot. One year after the beginning of her symptoms, she noticed enlargement of her left calf. X-ray studies disclosed L5-S1 disk degeneration. EMG showed muscle denervation with normal motor conduction velocity. Open biopsies of the gastrocnemius muscles were performed. The left gastrocnemius muscle showed hypertrophic type 2 fibers in comparison with the right gastrocnemius. Electron microscopy showed mildly increased number of mitochondria in these fibers. A satisfactory explanation for denervation hypertrophy has yet to be provided.

    The iliopsoas or iliopectineal comportment is a normal structure that occasionally communicates with the synovial cavity of the hip. Rarely, in association with certain pathologies that raise the intraarticular pressure, it becomes enlarged, producing an inguinal or pelvic mass, also referred to as iliopsas bursitis. We present five cases of this pathology detected over the past year in our hospitals. Three of the patients had undergone previous vascular punctures in the hip involved, one presented brucellosis-related arthropathy and the fifth had generative joint abnormalities. The plain radiography, arthrography, ultrasound, CT,CT-guided arthrography and MR images are provided and discussed. We present an etiological factor of this process (previous vascular puncture) that has not been previously reported in the literature. 13 refs

    Full Text Available Gingival enlargement in the interdental papillae, thickened, rounded gingival contour and discomfort became major issues that must be treated in order to be optimal appearance and function. Gingival enlargement that experienced fibrosis would not disappear with only plaque control, but required surgery that is gingivectomy and gingivoplasty. The 24-year-old woman came to the periodonsia clinic with complaints maxillary anterior gingiva swelled at teeth 11-21 with plaque index 52%. The depth of the tooth pocket 11: labial (mesial: 4, medial: 1, distal: 3. Palatal (mesial: 3, medial: 2, distal 1. The depth of the tooth pocket 21 is labial (mesial: 4, medial: 1, distal: 1, palatal (mesial: 3, medial: 1, distal 1. Gingivectomy treatment and gingivoplasty were performed with the aim of eliminating pockets and restore physiologic gingival contour which can help prevent the recurrence of the disease periodontal. In performing surgical gingivectomy and gingivoplasty, which must be considered is to minimize the disposal of gingival tissue to maintain the aesthetic, adequate access to the bone defect in order to make good corrections, and the minimization of bleeding and discomfort after surgery.

    The preventive effect of aggressive blood pressure lowering on hematoma enlargement was investigated in patients with ultra-acute spontaneous intracerebral hemorrhage (ICH). Retrospective review of 248 patients (145 males, 103 females) with spontaneous ICH treated in our hospital between 2005 and 2008 identified patients with ultra-acute ICH who were directly taken to our institute by ambulance within 3 hours after onset. Patients who could not be assessed twice by computed tomography (CT) within 24 hours after arrival were excluded. Systolic blood pressure (SBP) was aggressively controlled in all patients using intravenous nicardipine to below 140 mmHg as soon as possible after diagnosis of ICH with CT. Hematoma enlargement was defined as increase in volume of more than 33% or more than 12.5 ml in the first 24 hours. Hematoma enlargement was observed in 11 of the 73 patients (15.0%). The time course of SBP change was not significantly different in patients with and without hematoma enlargement. The incidence of hematoma enlargement in patients with ultra-acute ICH in this study was 15.0%, which was lower than that in other series in which blood pressure was not reduced aggressively. This finding suggests that aggressive SBP lowering to below 140 mmHg has a preventive effect on hematoma enlargement in patients with ultra-acute ICH. (author)

    Objective The aim of this study was to investigate the association among gingival enlargement (GE), periodontal conditions and socio-demographic characteristics in subjects undergoing fixed orthodontic treatment. Methods A sample of 330 patients undergoing fixed orthodontic treatment for at least 6 months were examined by a single calibrated examiner for plaque and gingival indexes, probing pocket depth, clinical attachment loss and gingival enlargement. Socio-economic background, orthodontic treatment duration and use of dental floss were assessed by oral interviews. Associations were assessed by means of unadjusted and adjusted Poisson's regression models. Results The presence of gingival bleeding (RR 1.01; 95% CI 1.00-1.01) and excess resin around brackets (RR 1.02; 95% CI 1.02-1.03) were associated with an increase in GE. No associations were found between socio-demographic characteristics and GE. Conclusion Proximal anterior gingival bleeding and excess resin around brackets are associated with higher levels of anterior gingival enlargement in subjects under orthodontic treatment.

    Josiane Costa Rodrigues de SA

    2013-12-01

    Full Text Available Asymptomatic mouth floor enlargements may be observed in edentulous patients. These masses, which protrude from the mouth floor, may complicate the fitting of dentures and require surgery. Whether this "entity" may be considered an anatomical variation of the mouth floor or represent specific alterations in the sublingual gland is not known. Objective: The aim of this work is to investigate the morphological and morphometric aspects of the sublingual glands of edentulous patients with mouth floor enlargements and compare the glands of these patients with the sublingual glands of human cadavers. Material and Methods: Microscopic evaluation was performed on human sublingual glands from edentulous patients with mouth floor enlargements (n=20 and edentulous cadavers (n=20. The patients and cadavers were of similar ages. The data were compared using Mann-Whitney U, Fisher's exact and Student's t tests (p0.05. Only the variables "autolysis" and "congested blood vessels" presented statistical difference between groups (p=0.014; p=0.043. The morphometric study revealed that the volume densities of acini, ducts, stroma and adipose tissue were similar between the groups (p>0.05. CONCLUSION: The microscopic characteristics of the sublingual glands in mouth floor enlargements in edentulous patients correspond to characteristics associated with the normal aging process. The glands are not pathological and represent an age-related alteration that occurs with or without the presence of the mouth floor enlargements.

  3. Tribological investigations of the applicability of surface functionalization for dry extrusion processes

    2017-10-01

    Cold extrusion processes are characterized by large relative contact stresses combined with a severe surface enlargement of the workpiece. Under these process conditions a high risk for galling of workpiece material to the tool steel occurs especially in processing of aluminum and aluminum alloys. In order to reduce adhesive wear lubricants for separation of workpiece and tool surfaces are used. As a consequence additional process steps (e.g. preparation and cleaning of workpieces) are necessary. Thus, the realization of a dry forming process is aspired from an environmental and economic perspective. In this paper a surface functionalization with self-assembled-monolayers (SAM) of the tool steels AISI D2 (DIN 1.2379) and AISI H11 (DIN 1.2343) is evaluated by a process-oriented tribological test. The tribological experiment is able to resemble and scale the process conditions of cold extrusion related to relative contact stress and surface enlargement for the forming of pure aluminum (Al99.5). The effect of reduced relative contact stress, surface enlargement and relative velocity on adhesive wear and tool lifetime is evaluated. Similar process conditions are achievable by different die designs with decreased extrusion ratios and adjusted die angles. The effect of surface functionalization critically depends on the substrate material. The different microstructure and the resulting differences in surface chemistry of the two tested tool steels appear to affect the performance of the tool surface functionalization with SAM.

    Full Text Available The liberalization of the European air opened the strictly regulated European market, and contributed to the appearance and quick spread of the Low-Cost Carriers (LCCs. At the beginning of the 21st century the low cost traffic absolutely concentrated on the Western European market but after the enlargement of the European Union (EU LCCs started their operations in Eastern Europe enlarging and enriching the former evolved network structures. The aim of this paper is to trace the evolution of the route network as a result of EU expansion. During the study we came to the conclusion that in the time period after the EU enlargement the European LCC traffic showed dynamic development, route networks widened and the number of accessible destinations doubled. Comparing the LCCs network structures we defined three main characteristics, which represents the North-South flows, the West-East routes and the mixed network structure.

    This study aimed to re-examine the conventional predictive factors for dissected aortic enlargement, such as the aortic and false lumen diameter and to consider whether the morphological elements of the dissected aorta could be predictors by quantifying the 'shape' of the true lumen based on elliptic Fourier analysis. A total of 80 patients with uncomplicated type B aortic dissection were included. The patients were divided into 'Enlargement group' and 'No Change group.' Between the 2 groups, the mean systolic blood pressure during follow-up, aortic and false lumen maximum diameters, and analysed morphological data were compared using each statistical method. The maximum aortic and false lumen diameters were significantly larger in the Enlargement group than in the No Change group (39.3 vs 35.9 mm; P = 0.0058) (23.5 vs 18.2 mm; P = 0.000095). The principal component 1, which is the data calculated by elliptic Fourier analysis, was significantly lower in the Enlargement group than in the No Change group (0.020 vs - 0.072; P = 0.000049). The mean systolic blood pressure ≥130 mmHg, aortic diameter, false lumen diameter and principal component 1 were included in the Cox proportional hazard model as covariates to determine the significant predictive variable. Principal component 1 demonstrated the only significance with aortic enlargement on multivariate analysis (odds ratio = 0.32; P = 0.048). The analysed and calculated morphological data of the shape of the true lumen can be more effective predictive factors of aortic enlargement of type B dissection than the conventional factors. © The Author 2017.

    Objective: To study the CT appearance of the hilar and mediastinal enlarged lymph nodes in coal worker's pneumoconiosis (CWP), its pathological basis and diagnostic value for CWR complicated with lung cancer. Methods: (1) Twelve isolated lungs with CWP obtained at autopsy were inflated and fixed. CT scan was performed. The pathologic findings of enlarged lymph nodes were identified. (2) CT findings of hilar and mediastinal enlarged lymph nodes of 71 cases with CWP and 22 cases of CWP complicated with lung cancer were analyzed. Results: (1) Most of the enlarged hilar and mediastinal lymph nodes in simple CWR was in third stage of fibrosis. The fourth stage of fibrosis was only seen in lymph nodes of a case with complicated CWP. In this case the necrotic materials of lymph nodes eroded adjacent bronchi and vessels, and coalesced with progressive massive fibrosis (PMF). (2) The average number of lymph nodes in cases of complicated CWP was more than that of simple CWP (P 2 cm was 7.4%. (3) The prevalence of lymph nodes calcification in CWP was 61.1%, but egg shell calcification was only 14.7%. (4) In the cases of CWP complicated with lung cancer, lymph node > 2 cm was 20.8%, that was more than CWP (P 3 cm was 7.6%. Conclusion: Lymph nodes up to 1 cm may have dust fibrosis and coal silicosis nodules. The lymph nodes >2 cm is more common in CWP complicated with lung cancer than in simple CWP. The lymph nodes > 3 cm indicates higher probability of CWP with lung cancer than PMF

    This manual describes the input required to use Version 1.1 of the SPARK computer code. SPARK 1.1 is a library of FORTRAN main programs and subprograms designed to calculate eddy currents on conducting surfaces where current flow is assumed zero in the direction normal to the surface. Surfaces are modeled with triangular and/or quadrilateral elements. Lorentz forces produced by the interaction of eddy currents with background magnetic fields can be output at element nodes in a form compatible with most structural analysis codes. In addition, magnetic fields due to eddy currents can be determined at points off the surface. Version 1.1 features eddy current streamline plotting with optional hidden-surface-removal graphics and topological enhancements that allow essentially any orientable surface to be modeled. SPARK also has extensive symmetry specification options. In order to make the manual as self-contained as possible, six appendices are included that present summaries of the symmetry options, topological options, coil options and code algorithms, with input and output examples. An edition of SPARK 1.1 is available on the Cray computers at the National Magnetic Fusion Energy Computer Center at Livermore, California. Another more generic edition is operational on the VAX computers at the Princeton Plasma Physics Laboratory and is available on magnetic tape by request. The generic edition requires either the GKS or PLOT10 graphics package and the IMSL or NAG mathematical package.

    Napier, Bruce A.

    2004-03-08

    The GENII Version 2 computer code was developed for the Environmental Protection Agency (EPA) at Pacific Northwest National Laboratory (PNNL) to incorporate the internal dosimetry models recommended by the International Commission on Radiological Protection (ICRP) and the radiological risk estimating procedures of Federal Guidance Report 13 into updated versions of existing environmental pathway analysis models. The resulting environmental dosimetry computer codes are compiled in the GENII Environmental Dosimetry System. The GENII system was developed to provide a state-of-the-art, technically peer-reviewed, documented set of programs for calculating radiation dose and risk from radionuclides released to the environment. The codes were designed with the flexibility to accommodate input parameters for a wide variety of generic sites. Operation of a new version of the codes, GENII Version 2, is described in this report. Two versions of the GENII Version 2 code system are available, a full-featured version and a version specifically designed for demonstrating compliance with the dose limits specified in 40 CFR 61.93(a), the National Emission Standards for Hazardous Air Pollutants (NESHAPS) for radionuclides. The only differences lie in the limitation of the capabilities of the user to change specific parameters in the NESHAPS version. This report describes the data entry, accomplished via interactive, menu-driven user interfaces. Default exposure and consumption parameters are provided for both the average (population) and maximum individual; however, these may be modified by the user. Source term information may be entered as radionuclide release quantities for transport scenarios, or as basic radionuclide concentrations in environmental media (air, water, soil). For input of basic or derived concentrations, decay of parent radionuclides and ingrowth of radioactive decay products prior to the start of the exposure scenario may be considered.

    Full Text Available Purpose. To report our findings in a case of orbital T-cell lymphoma in which all of the extraocular muscles (EOMs were bilaterally and discretely enlarged and the patient had a moon face countenance. Case. A 59-year-old woman presented with visual disturbances in her left eye, hyperemia in both eyes, and a moon face countenance. Examinations showed limited upward gaze in the right eye, blepharoptosis, hypertropia, and limited downward and rightward gaze in the left eye. Slit-lamp examination showed only chemosis and hyperemia of both eyes. Magnetic resonance imaging with contrast revealed discrete enlargements of the muscle bellies in all EOMs without abnormalities of the orbital fat in both eyes. Blood examinations excluded thyroid- and IgG4-related ophthalmopathy, and EOM biopsy revealed peripheral T-cell lymphoma. After beginning aggressive chemotherapy, the enlarged EOMs, limited eye motility, and moon face countenance improved. Unfortunately, the patient died of sepsis during the chemotherapy. Conclusions. A lymphoma should be included in the differential diagnosis of eyes with enlarged EOMs. Because lymphomas can lead to death, it is important for clinicians to consider lymphomas in eyes with enlarged EOMs.

    Winberg, Anders [ed.

    2004-08-01

    Site characterisation in the Oskarshamn area is currently conducted at two adjoining localities, the Simpevarp and Laxemar subareas. This report presents the interim version (model version Simpevarp 1.1 of S1.1 for short) of the preliminary Site Descriptive Model for the Simpevarp subarea. The basis for this interim version is quality-assured, geoscientific and ecological field data from the Simpevarp subarea (and in part from the Laxemar area) available in the SKB SICADA and GIS data bases as of July 1, 2003 as well as version 0 of the Site Descriptive Model. The new data collected during the initial site investigation phase up till the date of data freeze S1.1 constitute the basis for the update of version 0 to version S1.1. These data include results from surface investigations in the subarea with its regional environment and from drillings and investigations in boreholes. The surface-based data sets were, in a relative sense, extensive compared with data sets from boreholes, were the information largely was limited to information from one c. 1,000 m deep cored borehole (KSH01A), two existing cored boreholes and three c. 200 m deep percussion-drilled boreholes. Discipline-specific models are developed for the selected regional and local model volumes and these models are subsequently integrated into a unified site description. The current methodologies for developing discipline-specific models and their integration are documented in methodology/ strategy reports. In the present work, the procedures and guidelines given in those reports were followed to the extent possible given the data and information available at the time of data freeze for model version S1.1. Compared with version 0 there are considerable additional features in the version S1.1, especially in the geological description and in the description of the near surface. The geological models of lithology and deformation zones are based on borehole information and surface data of much higher

    Full Text Available A compositional approach to designing alloys that have an enlarged equiaxed zone is suggested in this study. The partitioning of elements during the solidification of CoCrFeMnNi high-entropy alloy (HEA was confirmed through a directional solidification quenching experiment. Several HEAs were designed to maximize the effects of constitutional and thermal undercooling by considering factors including solute enrichment at the columnar front and the melting temperatures and thermal conductivities of the individual elements. The newly designed HEAs were shown to have successfully enlarged equiaxed zones, and improved anisotropic properties.

  1. Significant Risk Factors for Postoperative Enlargement of Basal Ganglia Hematoma after Frameless Stereotactic Aspiration: Antiplatelet Medication and Concomitant IVH.

    Frameless stereotactic aspiration of a hematoma can be the one of the treatment options for spontaneous intracerebral hemorrhage in the basal ganglia. Postoperative hematoma enlargement, however, can be a serious complication of intracranial surgery that frequently results in severe neurological deficit and even death. Therefore, it is important to identify the risk factors of postoperative hematoma growth. During a 13-year period, 101 patients underwent minimally invasive frameless stereotactic aspiration for basal ganglia hematoma. Patients were classified into two groups according to whether or not they had postoperative hematoma enlargement in a computed tomography scan. Baseline demographic data and several risk factors, such as hypertension, preoperative hematoma growth, antiplatelet medication, presence of concomitant intraventricular hemorrhage (IVH), were analysed via a univariate statistical study. Nine of 101 patients (8.9%) showed hematoma enlargement after frameless stereotactic aspiration. Among the various risk factors, concomitant IVH and antiplatelet medication were found to be significantly associated with postoperative enlargement of hematomas. In conclusion, our study revealed that aspirin use and concomitant IVH are factors associated with hematoma enlargement subsequent to frameless stereotactic aspiration for basal ganglia hematoma.

The new data acquired during the initial site investigation phase to the date of data freeze 1.1 constitute the basis for the updating of version 0 to version 1.1. These data originate from surface investigations on the candidate area with its regional environment and from drilling and investigations in boreholes. The surface-based data sets were rather extensive whereas the data sets from boreholes were limited to information from one 1,000 m deep cored borehole (KFM01A) and eight 150 to 200 m deep percussion-drilled boreholes in the Forsmark candidate area. Discipline specific models are developed for a selected regional and local model volume and these are then integrated into a site description. The current methodologies for developing the discipline specific models and the integration of these are documented in methodology reports or strategy reports.

  5. Communities, Boundaries and New Neighbours: the Discursive Construction of EU Enlargement

    Directory of Open Access Journals (Sweden)

    Giuditta Caliendo

    2008-12-01

    Full Text Available The institutional discourse of the European Union (EU is undergoing important changes that are also reflected by new initiatives in its communication policy. Against a background of widespread scepticism towards EU enlargement among the public, this change is driven by the need to promote the widening of its borders in a more effective way in order to prompt popular endorsement. Through the use of its textual and visual communicative strategies, the EU is thus finding new ways to buttress its legitimacy and raise consensus around its political actions. The node of interaction between citizens and institutions is represented by the informative publications of the EU (also made available on the europa website, which become a constitutive element in building Union-to-citizen communication. The analysis of textual and visual formulations of the European Commission’s key booklets on EU enlargement in the period from 2004 to 2007 - in terms of their content and pragmatic aims - reveals the emergence of new consensus-building strategies. Results show that a sense of allegiance and belonging attributed to a deepening of European integration is now increasingly linked to the practical advantages of EU enlargement, as expressed through the use of ‘promotional’ and strategic discursive practices. Moving away from a merely informative content, communication modes ‘migrate’ towards a more direct and ‘commodified’ type of message, while an increase in visual elements plays a complementing role in promoting legitimacy and a feeling of mutual belonging between ‘old’ and ‘new’ members of the European family.

  6. New developments in program STANSOL version 3

    International Nuclear Information System (INIS)

    Gray, W.H.

    1981-10-01

    STANSOL is a computer program that applied a solution for the mechanical displacement, stress, and strain in rotationally-transversely isotropic, homogeneous, axisymmetric solenoids. Careful application of the solution permits the complex mechanical behavior of multilayered, nonhomogeneous solenoids to be examined in which the loads may vary arbitrarily from layer to layer. Loads applied to the solenoid model by program STANSOL may consist of differential temperature, winding preload, internal and/or external surface pressure, and electromagnetic Lorentz body forces. STANSOL version 3, the latest update to the original version of the computer program, also permits structural analysis of solenoid magnets in which frictionless interlayer gaps may open or close. This paper presents the new theory coded into version 3 of the STANSOL program, as well as the new input data format and graphical output display of the resulting analysis

    2017-05-01

    Obstructive hydrocephalus secondary to enlarged Virchow-Robin Spaces (VRS) is a rare entity, with only a few cases reported in the literature. Presenting symptoms vary widely from headaches to dizziness. We report a case of a 31-year-old man who presented with pulsatile tinnitus and magnetic resonance imaging showing obstructive hydrocephalus secondary to tumefactive VRS. After a cerebrospinal fluid diversion procedure in the form of an endoscopic third ventriculostomy, he had almost complete resolution of his symptoms. This is the first case of obstructive hydrocephalus secondary to enlarged VRS, presenting with pulsatile tinnitus. Copyright © 2017 Elsevier Inc. All rights reserved.

    2018-03-01

    Enlarged facial pores can be an early manifestation of skin aging and they are a common aesthetic concern for Asians. However, studies of improving the appearance of enlarged pores have been limited. The authors aimed to study the application of CO2 fractional laser treatment in patients with enlarged facial pores. A total of 32 patients with dilated facial pores completed 3 consecutive sessions of low energy level treatments with a fractional CO2 laser at 4-week intervals. Image analysis was performed to calculate the number of enlarged pores before each treatment session and 12 weeks after the final treatment. After application of laser treatments, there was a significant decrease in the number of enlarged pores. The mean number of enlarged pores was decreased by 28.8% after the second session and by 54.5% at post-treatment evaluation. Post-treatment side effects were mild and transitory. Histological and immunohistochemical analyses demonstrated clear increases in the number of collagen fibers and the expression of transforming growth factor-β1. The short-term results showed that treatment with low energy level CO2 fractional laser therapy could be a safe and effective option for patients with Fitzpatrick skin Types III and IV who are concerned with enlarged pores.

    Full Text Available Pathognomonic sign of grouper sleepy disease iridovirus (GSDIV was proposed to be the formation of enlarged cells and necrotic cells, in which under electron microscope, it is revealed to be the inclusion body bearing cells (IBCs and necrotic cells containing GSDIV viral particles. Spleen and kidney tissues are the major sites for formation of enlarged cells. This paper described the result of histopatological analysis of enlarged cells found in the spleen and kidney of moribund fish after GSDIV challenge. A pathogenicity test was conducted on fish stocked in two tanks for infected groups and the other two tanks for uninfected control groups (15 fish per tank. The infected groups were injected intramuscularly with 0.1 ml of the viral inoculum. The uninfected groups were injected with the same amount of EMEM-2. The GSDIV-infected humpback grouper began to die after 6 days post infection and all died after 7 dpi, excluding one fish which had survived until the end of experimental infection periods (93% to 100% mortality. All of the diseased fish showed massive formation of enlarged cells in their spleen, head kidney and trunk kidney. The largest number of enlarged cells was observed on head kidneys and subsequently followed by spleens, trunk kidney (2.0-200.3/field of view. This result suggested that the number of enlarged cells in the affected organs was not the direct factor that led to the mortality of fish.

    Full Text Available Enlargement of the left atrium is perceived as a part of athlete’s heart syndrome, despite the lack of evidence. So far, left atrial size has not been assessed in the context of exercise capacity. The hypothesis of the present study was that LA enlargement in athletes was physiological and fitness-related condition. In addition, we tried to assess the feasibility and normal values of left atrial strain parameters and their relationship with other signs of athlete’s heart. The study group consisted of 114 international-level rowers (17.5 ± 1.5 years old; 46.5% women. All participants underwent a cardio-pulmonary exercise test and resting transthoracic echocardiography. Beside standard echocardiographic measurements, two dimensional speckle tracking echocardiography was used to assess average peak atrial longitudinal strain, peak atrial contraction strain and early left atrial diastolic longitudinal strain. Mild, moderate and severe left atrial enlargement was present in 27.2°%, 11.4% and 4.4% athletes, respectively. There were no significant differences between subgroups with different range of left atrial enlargement in any of echocardiographic parameters of the left ventricle diastolic function, filling pressure or hypertrophy. A significant correlation was found between the left atrial volume index and maximal aerobic capacity (R > 0.3; p < 0.001. Left atrial strain parameters were independent of atrial size, left ventricle hypertrophy and left ventricle filling pressure. Decreased peak atrial longitudinal strain was observed in 4 individuals (3.5%. We concluded that LA enlargement was common in healthy, young athletes participating in endurance sport disciplines with a high level of static exertion and was strictly correlated with exercise capacity, therefore, could be perceived as another sign of athlete’s heart.

    The purpose of this study was to determine the added value of the perimedullary spinal vein enlargement sign on magnetic resonance imaging (MRI) in distinguishing intradural-extramedullary tumors (IDEMTs) from intramedullary spinal tumors (IMTs). Two hundred and eight consecutive spinal intradural tumors with histopathologic confirmation (21 IMTs, 187 IDEMTs) were enrolled. Two readers blinded to the final pathological diagnosis and clinical data independently assessed the venous enlargement sign to determine the agreement between them and jointly distinguished IDEMTs from IMTs according to the common MRI findings. Sensitivity, specificity, and accuracy for the diagnosis of IDEMTs were calculated for the common MRI findings, vein enlargement sign, and a combination of both. Intraobserver agreement and interobserver agreement for both readers was excellent. The sensitivity, specificity, and accuracy of common MRI findings for differentiating IDEMTs from IMTs were 83.4, 95.2, and 89.3 %, respectively. Thirty-one IDEMTs were mistakenly diagnosed as IMTs, in which seven were cases with vein enlargement signs. By applying the vein enlargement sign to the common MRI findings, the specificity remained at 95.2 %, while the sensitivity improved to 89.3 % and the accuracy increased to 92.3 %. The spinal perimedullary vein enlargement sign is useful in assessing intradural tumors and to differentiate IDEMTs from IMTs. (orig.)

    The Swedish Nuclear Fuel and Waste Management Company (SKB) is conducting site investigations at two different locations, the Forsmark and Simpevarp areas, with the objective of siting a geological repository for spent nuclear fuel. The results from the investigations at the sites are used as a basic input to the development of Site Descriptive Models (SDM). The SDM shall summarise the current state of knowledge of the site, and provide parameters and models to be used in further analyses within Safety Assessment, Repository Design and Environmental Impact Assessment. The present report is a background report describing the meteorological conditions and the modelling of surface hydrology and near-surface hydrogeology in support of the Forsmark version 1.2 SDM based on the data available in the Forsmark 1.2 'data freeze' (July 31, 2004). The groundwater is very shallow, with groundwater levels within one meter below ground as an annual mean for almost all groundwater monitoring wells. Also, the annual groundwater level amplitude is less than 1.5 m for most wells. The shallow groundwater levels mean that there is a strong interaction between evapotranspiration, soil moisture and groundwater. In the modelling, surface water and near-surface groundwater divides are assumed to coincide. The small-scale topography implies that many local, shallow groundwater flow systems are formed in the Quaternary deposits, overlaying more large-scale flow systems associated with groundwater flows at greater depths. Groundwater level time series from wells in till and bedrock within the same areas show a considerably higher groundwater level in the till than in the bedrock. The observed differences in levels are not fully consistent with the good hydraulic contact between overburden and bedrock indicated by the hydraulic tests in the Quaternary deposits. However, the relatively lower groundwater levels in the bedrock may be caused by the horizontal to sub-horizontal highly

    The original SIMION was an electrostatic lens analysis and design program developed by D.C. McGilvery at Latrobe University, Bundoora Victoria, Australia, 1977. SIMION for the PC, developed at the Idaho National Engineering Laboratory, shares little more than its name with the original McGilvery version. INEL`s fifth major SIMION release, version 6.0, represents a quantum improvement over previous versions. This C based program can model complex problems using an ion optics workbench that can hold up to 200 2D and/or 3D electrostatic/magnetic potential arrays. Arrays can have up to 10,000,000 points. SIMION 3D`s 32 bit virtual Graphics User Interface provides a highly interactive advanced user environment. All potential arrays are visualized as 3D objects that the user can cut away to inspect ion trajectories and potential energy surfaces. User programs have been greatly extended in versatility and power. A new geometry file option supports the definition of highly complex array geometry. Extensive algorithm modifications have dramatically improved this version`s computational speed and accuracy.

    1985-01-01

    Brain CT studies of 35 patients with anoxia nervosa confirmed the observations of other authors: cerebral dystrophic changes correlate with weight loss and the reversibility of these changes also correlates with the normalization of body weight. Other corroborated facts are: the most numerous and most pronounced enlargements are of the cortical sulci and the interhemispheric fissure, moderate widening affects the ventricles and the rarest and most insignificant changes are those of the cerebellum. The reversibility of the changes showed a parallel to the extent of the changes themselves and to the duration of improvement of the body weight. The reversibility of the enlargement of the cortical sulci and of the distances between the frontal horns of the lateral ventricles was more often significant than that of the abnormal measurements of the cella media. This difference is based on minimal early acquired brain damage which occurs in 60% of our patients. This high incidence of early acquired minimal brain disease in patients with anorexia nervosa is here discussed as a nonspecific predisposing factor. Although there is no exact explanation of the etiology of the reversible enlargement of cerenral spinal fluid (CSF) spaces in anorexia nervosa, the changes resemble those in alcoholics. The mechanisms of brain changes in alcoholism, as shown experimentally, seem to us to throw light on the probable mechanism of reversible dystrophic brain changes in anorexia nervosa. (orig.)

    Full Text Available Adolescent-onset exposure to highly addictive substances such as opiates may induce far-reaching deleterious effects on later mental and physical health. However, little is known about the neurodevelopmental basis for adolescent-onset opiate dependence. Here we examined whether having an abnormally large cavum septum pellucidum (CSP, a putative marker of limbic structural maldevelopment, is associated with opiate dependence particularly beginning in adolescence.The overall length of the CSP and the prevalence of abnormal enlargement of the CSP were assessed and compared in 65 opiate-dependent subjects (41 adolescent-onset opiate users and 24 adult-onset opiate users and 67 healthy subjects.Opiate-dependent subjects showed a greater prevalence of abnormal CSP enlargement relative to healthy subjects (odds ratio [OR]=3.64, p=0.034. The overall CSP length of adolescent-onset opiate-dependent subjects was greater, as compared not only with healthy subjects (F₁,₁₀₄=11.03, p=0.001 but also with those who began opiate use during adulthood (F₁,₆₁=4.43, p=0.039.The current findings provide the first evidence that abnormal CSP enlargement, which reflects limbic system dysgenesis of neurodevelopmental origin, may be linked to later development of opiate dependence. In addition, a greater CSP length, which indicates more severe limbic abnormalities, appears to confer higher risk for earlier onset of opiate use.

    Follow-up computed tomography angiography (CTA) scans add considerable postimplantation costs to endovascular aneurysm repairs (EVARs) of abdominal aortic aneurysms (AAAs). By building a risk model, we hope to identify patients at low risk for aneurysm sac enlargement to minimize unnecessary CTAs. 895 consecutive patients who underwent EVAR for AAA were reviewed, of which 556 met inclusion criteria. A Probit model was created for aneurysm sac enlargement, with preoperative aneurysm morphology, patient demographics, and operative details as variables. Our final model included 287 patients and had a sensitivity of 100%, a specificity of 68.9%, and an accuracy of 70.4%. Ninety-nine (35%) of patients were assigned to the high-risk group, whereas 188 (65%) of patients were assigned to the low-risk group. Notably, regarding anatomic variables, our model reported that age, pulmonary comorbidities, aortic neck diameter, iliac artery length, and aneurysms were independent predictors of post-EVAR sac enlargement. With the exception of age, all statistically significant variables were qualitatively supported by prior literature. With regards to secondary outcomes, the high-risk group had significantly higher proportions of AAA-related deaths (5.1% versus 1.1%, P = 0.037) and Type 1 endoleaks (9.1% versus 3.2%, P = 0.033). Our model is a decent predictor of patients at low risk for post AAA EVAR aneurysm sac enlargement and associated complications. With additional validation and refinement, it could be applied to practices to cut down on the overall need for postimplantation CTA. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available Tuberculosis (TB is a chronic specific granulomatous disease and a major cause of death in developing countries. The clinical presentation of TB lesions of the oral cavity varies widely and can manifest as ulcerations, diffuse inflammatory lesions, granulomas and fissures. Oral lesions generally appear secondary to primary TB infection elsewhere, although primary infection of the oral mucosa by Mycobacterium tuberculosis has also been described. We hereby report a case of primary TB of the gingiva manifesting as gingival enlargement. Diagnosis was based on histopathological examination, complete blood count, X-ray chest and immunological investigations with detection of antibodies against M. tuberculosis. Anti-tuberculous therapy was carried out for over 6 months and was followed by surgical excision of the residual enlargement under local anesthesia. After 1-year follow-up, there was no recurrence of the disease. This case report emphasizes the need for dentists to include TB in the differential diagnosis of various types of gingival enlargements.

  7. Cell enlargement of plant tissue explants oscillates with a temperature-compensated period of ca. 24 min

    Rate of plant cell enlargement, measured at intervals of 3 min using a sensitive linear transducer, oscillates with a minimum period of about 24 min that parallels the 24-min periodicity observed with the oxidation of NADH by the external plasma membrane NADH oxidase and of single cells measured previously by video-enhanced light microscopy. Also exhibiting 24-min oscillations is the steady-state rate of cell enlargement induced by the addition of the auxin herbicide 2,4-dichlorophenoxyacetic acid (2,4-D) or the natural auxin indole-3-acetic acid (IAA). Immediately following 2,4-D addition, a very complex pattern of oscillations is frequently observed. However, after several hours a dominant 24-min period emerges. The length of the 24-min period is temperature compensated and remains constant at 24 min when measured at 15, 25 or 35 degrees C, despite the fact that the rate of cell enlargement approximately doubles for each 10 degree C rise over this same range of temperatures.

    Full Text Available Antiphospholipid antibody (APLA syndrome is a noninflammatory autoimmune disease, with innumerable clinical manifestations ranging from recurrent thrombosis and pregnancy morbidity to valvular lesions, transverse myelitis, thrombocytopenia, and hemolytic anemia. APLAs in antiphospholipid syndrome (APS are well-known risk factors for cerebrovascular accidents. Stroke is the most common manifestation of APS in the central nervous system. Gingival enlargement is a known side effect of phenytoin which is an antiepileptic drug. This can have a significant effect on the quality of life as well as increasing the oral bacterial load by generating plaque retention sites. The management of gingival overgrowth seems to be directed at controlling gingival inflammation through a good oral hygiene regimen. Thus, this case report aims to describe the conservative management of phenytoin-induced gingival enlargement combined with inflammatory enlargement in a patient with APLA syndrome.

    Environment and Climate Change Canada (ECCC) is implementing a 2.5-km resolution version of the Global Environmental Multiscale (GEM) model over the Canadian Arctic. Radiosonde observations were used to evaluate the numerical representation of surface-based temperature inversion which is a major feature in the Arctic region. Arctic surface-based inversions are often created by imbalance between radiative cooling processes at surface and warm air advection above. This can have a significant effect on vertical mixing of pollutants and moisture, and ultimately, on cloud formation. It is therefore important to correctly predict the existence of surface inversions along with their characteristics (i.e., intensity and depth). Previous climatological studies showed that the frequency and intensity of surface-based inversions are larger during colder months in the Arctic. Therefore, surface-based inversions were estimated using radiosonde measurements during winter (December 2015 to February 2016) at Iqaluit (Nunavut, Canada). Results show that the inversion intensity can exceed 10 K with depths as large as 1 km. Preliminary evaluation of GEM outputs reveals that the model tends to underestimate the intensity of near-surface inversions, and in some cases, the model failed to predict an inversion. This study presents the factors contributing to this bias including surface temperature and snow cover.

    Site characterisation in the Oskarshamn area is currently conducted at two adjoining localities, the Simpevarp and Laxemar subareas. This report presents the interim version (model version Simpevarp 1.1 of S1.1 for short) of the preliminary Site Descriptive Model for the Simpevarp subarea. The basis for this interim version is quality-assured, geoscientific and ecological field data from the Simpevarp subarea (and in part from the Laxemar area) available in the SKB SICADA and GIS data bases as of July 1, 2003 as well as version 0 of the Site Descriptive Model. The new data collected during the initial site investigation phase up till the date of data freeze S1.1 constitute the basis for the update of version 0 to version S1.1. These data include results from surface investigations in the subarea with its regional environment and from drillings and investigations in boreholes. The surface-based data sets were, in a relative sense, extensive compared with data sets from boreholes, were the information largely was limited to information from one c. 1,000 m deep cored borehole (KSH01A), two existing cored boreholes and three c. 200 m deep percussion-drilled boreholes. Discipline-specific models are developed for the selected regional and local model volumes and these models are subsequently integrated into a unified site description. The current methodologies for developing discipline-specific models and their integration are documented in methodology/ strategy reports. In the present work, the procedures and guidelines given in those reports were followed to the extent possible given the data and information available at the time of data freeze for model version S1.1. Compared with version 0 there are considerable additional features in the version S1.1, especially in the geological description and in the description of the near surface. The geological models of lithology and deformation zones are based on borehole information and surface data of much higher

  13. The relative contributions of facial shape and surface information to perceptions of attractiveness and dominance.

    Jaimie S Torrance

    Full Text Available Although many studies have investigated the facial characteristics that influence perceptions of others' attractiveness and dominance, the majority of these studies have focused on either the effects of shape information or surface information alone. Consequently, the relative contributions of facial shape and surface characteristics to attractiveness and dominance perceptions are unclear. To address this issue, we investigated the relationships between ratings of original versions of faces and ratings of versions in which either surface information had been standardized (i.e., shape-only versions or shape information had been standardized (i.e., surface-only versions. For attractiveness and dominance judgments of both male and female faces, ratings of shape-only and surface-only versions independently predicted ratings of the original versions of faces. The correlations between ratings of original and shape-only versions and between ratings of original and surface-only versions differed only in two instances. For male attractiveness, ratings of original versions were more strongly related to ratings of surface-only than shape-only versions, suggesting that surface information is particularly important for men's facial attractiveness. The opposite was true for female physical dominance, suggesting that shape information is particularly important for women's facial physical dominance. In summary, our results indicate that both facial shape and surface information contribute to judgments of others' attractiveness and dominance, suggesting that it may be important to consider both sources of information in research on these topics.

    First aim of the study was to define normal shape and diameter of the internal auditory canal (IAC). In the second part the clinical relevance of IAC-enlargement was analyzed, considering also lesions of the subtle structures at the fundus of the internal auditory canal. 440 high resolution CT-scans of the temporal bone were used for retrospective analysis of the internal auditory canal and its fundus region. The mean value of the IAC diameter in axial and coronal plane was determined. In 20 of 440 patients IAC enlargement was found. In the group with pronounced enlargement (3fold SD) nearly all patients suffered from hearing impairment. In some of them we found structural abnormalities near the IAC fundus in the CSF/perilymph border zone. A new CT-based definition of normal shape and diameter of the internal auditory canal is presented. There is some evidence that a pathologic transmission of CSF-pressure in case of IAC-enlargement and/or abnormal fistulous communications could play an important role in the pathophysiology of hearing loss.

    To evaluate the presence, size and location of enlarged mediastinal lymph nodes (LNs) in patients with valvular heart disease (VHD) using computed tomography scans in correlation with ejection fraction (EF). We retrospectively evaluated 30 patients with VHD, without pre-existing diseases that could cause lymphadenopathy (LAP). The presence, size, and location of LNs greater than 1 cm in short axis diameter were evaluated. The location of mediastinal LNs was recorded according to the International Association for the Study of Lung Cancer. Furthermore, we evaluated the presence of pulmonary edema, pleural effusion, and other thoracic abnormalities and evaluated EF of the heart on transthoracic echocardiography. Sixteen patients (53%) had at least 1 enlarged mediastinal LN. The most frequent locations were lower paratracheal (4R, n = 8/4L, n = 6), subcarinal (7, n = 5) and right upper paratracheal (2R, n = 4) regions. The frequency of mediastinal LAP was higher in patients with aortic regurgitation (2 of 2, 100%) followed by mitral regurgitation (8 of 11, 73%); it was also high in patients with pulmonary edema (80%), pleural effusion (81%), or both (77%), as compared to patients without pulmonary edema or pleural effusion (17%) (p = 0.001). Ten of 30 patients showed an abnormal EF of < 55%; among them, 8 had mediastinal LAP. However, the relationship between EF and LAP was not statistically significant (p = 0.058). Mediastinal LN enlargement is common in patients with VHD, especially in cases of pulmonary edema and pleural effusion. Enlarged mediastinal LNs were frequently observed with abnormal EF, however, the relationship between EF and mediastinal LAP was not statistically significant.

  18. Smooth surfaces from bilinear patches: Discrete affine minimal surfaces

    2013-06-01

    Motivated by applications in freeform architecture, we study surfaces which are composed of smoothly joined bilinear patches. These surfaces turn out to be discrete versions of negatively curved affine minimal surfaces and share many properties with their classical smooth counterparts. We present computational design approaches and study special cases which should be interesting for the architectural application. 2013 Elsevier B.V.

    To investigate parameters associated with hematoma enlargement in non-vitamin K antagonist oral anticoagulant (NOAC)-related intracerebral hemorrhage (ICH). This retrospective cohort study includes individual patient data for 190 patients with NOAC-associated ICH over a 5-year period (2011-2015) at 19 departments of neurology across Germany. Primary outcome was the association of prothrombin complex concentrate (PCC) administration with hematoma enlargement. Subanalyses were calculated for blood pressure management and its association with the primary outcome. Secondary outcomes include associations with in-hospital mortality and functional outcome at 3 months assessed using the modified Rankin Scale. The study population for analysis of primary and secondary outcomes consisted of 146 NOAC-ICH patients with available follow-up imaging. Hematoma enlargement occurred in 49/146 (33.6%) patients with NOAC-related ICH. Parameters associated with hematoma enlargement were blood pressure ≥ 160mmHg within 4 hours and-in the case of factor Xa inhibitor ICH-anti-Xa levels on admission. PCC administration prior to follow-up imaging was not significantly associated with a reduced rate of hematoma enlargement either in overall NOAC-related ICH or in patients with factor Xa inhibitor intake (NOAC: risk ratio [RR] = 1.150, 95% confidence interval [CI] = 0.632-2.090; factor Xa inhibitor: RR = 1.057, 95% CI = 0.565-1.977), regardless of PCC dosage given or time interval until imaging or treatment. Systolic blood pressure levels < 160mmHg within 4 hours after admission were significantly associated with a reduction in the proportion of patients with hematoma enlargement (RR = 0.598, 95% CI = 0.365-0.978). PCC administration had no effect on mortality and functional outcome either at discharge or at 3 months. In contrast to blood pressure control, PCC administration was not associated with a reduced rate of hematoma enlargement in NOAC-related ICH

  20. Enlarged clitoris in wild polar bears (Ursus maritimus) can be misdiagnosed as pseudohermaphroditism

    A 23-year-old female polar bear (Ursus maritimus) killed in an Inuit hunt in East Greenland on July 9, 1999 had a significantly enlarged clitoris resembling, in size, form and colour, those of previously reported 'pseudohermaphroditic' polar bears from Svalbard. It has been suggested that an enzyme...... and internal reproductive organs of the present were similar to a reference group of 23 normal adult female polar bears from East Greenland collected in 1999-2002. The aberrant bear was a female genotype, and macroscopic examination of her internal reproductive organs indicated that she was reproductively....... It is hence possible that the previously reported adult female polar bear pseudohermaphrodites from Svalbard are in fact misdiagnoses. Therefore, future studies examining pseudohermaphroditism in wildlife should consider that certain occurrences are natural events, e.g., enlarged clitoris in the present East...

    2013-01-01

    Objective. We evaluate if axial-based lymph node size criteria can be applied to coronal and sagittal planes. Methods. Fifty pretreatment computed tomographic (CT) neck exams were evaluated in patients with head and neck squamous cell carcinoma (SCCa) and neck lymphadenopathy. Axial-based size criteria were applied to all 3 imaging planes, measured, and classified as "enlarged" if equal to or exceeding size criteria. Results. 222 lymph nodes were "enlarged" in one imaging plane; however, 53.2% (118/222) of these were "enlarged" in all 3 planes. Classification concordance between axial versus coronal/sagittal planes was poor (kappa = -0.09 and -0.07, resp., P planes. Conclusion. Classification of "enlarged" lymph nodes differs between axial versus coronal/sagittal imaging planes when axial-based nodal size criteria are applied independently to all three imaging planes, and exclusively used without other morphologic nodal data.

  2. Channel erosion in a rapidly urbanizing region of Tijuana, Mexico: Enlargement downstream of channel hardpoints

    Urban-induced erosion in Tijuana, Mexico, has led to excessive sediment deposition in the Tijuana Estuary in the United States. Urban areas in developing countries, in contrast to developed countries, are characterized by much lower proportions of vegetation and impervious surfaces due to limited access to urban services such as road paving and landscaping, and larger proportions of exposed soils. In developing countries, traditional watershed scale variables such as impervious surfaces may not be good predictors of channel enlargement. In this research, we surveyed the stream channel network of an erodible tributary of the Tijuana River Watershed, Los Laureles Canyon, at 125 locations, including repeat surveys from 2008. Structure from Motion (SfM) and 3D photo-reconstruction techniques were used to create digital terrain models of stream reaches upstream and downstream of channel hardpoints. Channels are unstable downstream of hardpoints, with incision up to 2 meters and widening up to 12 meters. Coordinated channelization is essential to avoid piece-meal approaches that lead to channel degradation. Watershed impervious area is not a good predictor of channel erosion due to the overriding importance of hardpoints and likely to the high sediment supply from the unpaved roads which prevents channel erosion throughout the stream network.

    Highlights: • Apparent contact angle equation of all wetting states on dual-scale rough surfaces is derived. • Structured sidewalls can improve superhydrophobicity than smooth sidewalls. • Structured sidewalls can enlarge ACA than smooth sidewalls. • Structured sidewalls present an advantage over smooth sidewalls in terms of enhancing superhydrophobic stability. - Abstract: The superhydrophobicity of biological surfaces with dual-scale roughness has recently received considerable attention because of the unique wettability of such surfaces. Based on this, artificial micro/nano hierarchical structures with structured sidewalls and smooth sidewalls were designed and the influences of sidewall configurations (i.e., structured and smooth) on the wetting state of micro/nano hierarchical structures were systematically investigated based on thermodynamics and the principle of minimum free energy. Wetting transition and superhydrophobic stability were then analyzed for a droplet on dual-scale rough surfaces with structured and smooth sidewalls. Theoretical analysis results show that dual-scale rough surfaces with structured sidewalls have a larger “stable superhydrophobic region” than those with smooth sidewalls. The dual-scale rough surfaces with smooth sidewalls can enlarge the apparent contact angle (ACA) without improvement in the superhydrophobic stability. By contrast, dual-scale rough surfaces with structured sidewalls present an advantage over those with smooth sidewalls in terms of enlarging ACA and enhancing superhydrophobic stability. The proposed thermodynamic model is valid when compared with previous experimental data and numerical analysis results, which is helpful for designing and understanding the wetting states and superhydrophobic stability of surfaces with dual-scale roughness.

    The well known superfluid model (or quasiparticle phonon nuclear model (QPNM)) of atomic nucleus is enlarged by including an adequate four-nucleon effective interaction in addition to the pairing and long-range effective residual interactions. New experimental data can be explained without affecting those observables already described by the QPNM and in addition new features can be enumerated: 1) superfluidities of the neutron and proton systems may be generated by one another; 2) the phase structure is enriched by a new superfluid phase dominated by alpha-type correlations (ATC) and 3) superfluid isomers and their bands of elementary excitations are predicted. Unusual large two-nucleon and alpha transfer reactions cross sections as well as some unusual large alpha decay widths can be explained. (author). 46 refs, 3 figs, 2 tabs

    Customization of the tracheoesophageal (TE) voice prosthesis (VP) is often preferred over surgical closure to prevent aspiration around the VP in laryngectomized patients with an enlarged tracheoesophageal puncture (TEP), but it has not been thoroughly evaluated. Single-institution prospective trial. A prospective trial was conducted to evaluate the effectiveness of a customized VP with the addition of an enlarged tracheal and/or esophageal collar in patients with leakage around an enlarged TEP. Absence of leakage around the VP after placement defined immediate effectiveness. Long-term success was defined by the prevention of adverse events related to leakage during the study period. Events that defined failure included: permanent gastrostomy dependence, aspiration pneumonia, and/or surgical TEP closure. Twenty-one patients with enlarged TEP were enrolled (2003-2006). Insertion of a customized VP was unsuccessful in one patient; 145 customizations were performed in the remaining 20 patients (median, 3.5 customizations) during the trial period. Of the customizations, 77% (112/145) prevented leakage immediately after VP insertion. The most common adverse event was dislodgement of the prosthesis (11%) or the collar alone (7%) in 18% (26/145) of customized VP placements. Six patients who died of disease were not evaluable for long-term outcomes. Long-term success was achieved in 80% (12/15) of evaluable patients who avoided permanent gastrostomy, aspiration pneumonia, and surgical TEP closure. Prosthetic customization offers an effective method to prevent leakage around the VP in many patients with an enlarged TEP, thereby preserving TE voice while avoiding surgical closure in this high-risk population.

    To assess bone tunnel enlargement after anterior cruciate ligament (ACL) reconstruction with the use of hamstring tendons fixed with a round cannulated interference (RCI) screw in the femur. A consecutive series of 30 ACL reconstructions performed with hamstring tendons fixed with an RCI screw in the femur and with staples via Leeds-Keio ligament in the tibia was retrospectively reviewed. The clinical outcome was evaluated through the Lysholm score. Anterior instability was tested by Telos-SE (Telos Japan, Tokyo, Japan) measurement. The location and angle of each femoral and tibial tunnel were measured with the use of plain radiographs, and bone tunnel enlargement greater than 2 mm detected any time 3, 6, 12, and 24 months postoperatively was defined as positive. Each factor (location and angle of the tunnels, sex, affected side, age, Lysholm score, and Telos-SE measurement) was compared between enlarged and nonenlarged groups. Positive enlargement of the bone tunnel (>2.0 mm) was observed in 36.7% (11 of 30) on the femoral side and 33.3% (10 of 30) on the tibial side, and in 6 knees of both sides. Half of patients (15 of 30) had an enlarged tunnel on the femoral or the tibial side until 1 year postoperatively. In most cases, enlargement reached maximum at 6 months postoperatively. Female patients tended to have an enlarged tunnel, especially on the femoral side (P < .05). Tunnel enlargement was not correlated with location and angle of the tunnels. Moreover, no difference was found in Lysholm score and Telos-SE measurement between enlarged and nonenlarged groups, although the nonenlarged group tended to exhibit higher Lysholm score and lesser instability. Bone tunnel enlargement of the femoral or tibial side was observed in half of patients (6 in both sides, 5 only in the femur, and 4 only in the tibia) after ACL reconstruction was performed with a hamstring tendon fixed with an RCI screw. Female patients had a greater chance for enlargement of the femoral tunnel

    The purpose of this work is to identify the role of incomplete partition type II on hearing loss among patients with enlarged vestibular aqueduct (EVA). EVA is a common congenital inner ear malformation among children with hearing loss, where vestibular aqueduct morphology in this population has been shown to correlate to hearing loss. However, the impact of incomplete partition between cochlear turns on hearing loss has not been, despite meaningful implications for EVA pathophysiology. A retrospective review of radiology reports for patients who had computed tomography (CT) scans with diagnoses of hearing loss at a tertiary medical center between January 2000 and June 2016 were screened for EVA. CT scans of the internal auditory canal (IAC) for those patients with EVA were examined for evidence of incomplete partition type II (IP-II), measurements of midpoint width and operculum width a second time, and patients meeting Cincinnati criteria for EVA selected for analysis. Statistical analysis including chi-square, Wilcoxon rank-sum, and t-tests were used to identify differences in outcomes and clinical predictors, as appropriate for the distribution of the data. Linear mixed models of hearing test results for all available tests were constructed, both univariable and adjusting for vestibular aqueduct morphometric features, with ear-specific intercepts and slopes over time. There were no statistically significant differences in any hearing test results or vestibular aqueduct midpoint and operculum widths. Linear mixed models, both univariable and those adjusting for midpoint and operculum widths, did not indicate a statistically significant effect of incomplete partition type II on hearing test results. Hearing loss due to enlarged vestibular aqueduct does not appear to be affected by the presence of incomplete partition type II. Our results suggest that the pathophysiological processes underlying hearing loss in enlarged vestibular aqueduct may not be a result of

    To analyze the rate of successful external cephalic versions in our center and caesarean sections that would be avoided with the use of external cephalic versions. From January 2012 to March 2016 external cephalic versions carried out at our center, which were a total of 52. We collected data about female age, gestational age at the time of the external cephalic version, maternal body mass index (BMI), fetal variety and situation, fetal weight, parity, location of the placenta, amniotic fluid index (ILA), tocolysis, analgesia, and newborn weight at birth, minor adverse effects (dizziness, hypotension and maternal pain) and major adverse effects (tachycardia, bradycardia, decelerations and emergency cesarean section). 45% of the versions were unsuccessful and 55% were successful. The percentage of successful vaginal delivery in versions was 84% (4% were instrumental) and 15% of caesarean sections. With respect to the variables studied, only significant differences in birth weight were found; suggesting that birth weight it is related to the outcome of external cephalic version. Probably we did not find significant differences due to the number of patients studied. For women with breech presentation, we recommend external cephalic version before the expectant management or performing a cesarean section. The external cephalic version increases the proportion of fetuses in cephalic presentation and also decreases the rate of caesarean sections.

    We report here a neurocranial abnormality previously undescribed in Pleistocene human fossils, an enlarged parietal foramen (EPF) in the early Late Pleistocene Xujiayao 11 parietal bones from the Xujiayao (Houjiayao) site, northern China. Xujiayao 11 is a pair of partial posteromedial parietal bones from an adult. It exhibits thick cranial vault bones, arachnoid granulations, a deviated posterior sagittal suture, and a unilateral (right) parietal lacuna with a posteriorly-directed and enlarged endocranial vascular sulcus. Differential diagnosis indicates that the perforation is a congenital defect, an enlarged parietal foramen, commonly associated with cerebral venous and cranial vault anomalies. It was not lethal given the individual's age-at-death, but it may have been associated with secondary neurological deficiencies. The fossil constitutes the oldest evidence in human evolution of this very rare condition (a single enlarged parietal foramen). In combination with developmental and degenerative abnormalities in other Pleistocene human remains, it suggests demographic and survival patterns among Pleistocene Homo that led to an elevated frequency of conditions unknown or rare among recent humans.

    Current treatments for acne scars and enlarged facial pores have shown limited efficacy. To evaluate the efficacy and safety of the fractional photothermolysis system (FPS) with dynamic operating mode on acne scars and enlarged pores. Twelve patients with mild to moderate atrophic acne scars and enlarged pores were included in this study. Three sessions of FPS treatment were performed for acne scars and facial pores monthly. Two blinded dermatologists who compared before and after photos based on a quartile grading scale conducted objective clinical assessments of acne scar- and facial pore-treated areas. We took a biopsy immediately after one treatment with the laser from one of the authors to assess the histologic effects of the laser on facial pores. Follow-up results at 4 months after the last treatment revealed that, of the 12 patients, for acne scars, five demonstrated clinical improvements of 51% to 75% and three demonstrated improvements of 76% to 100%, and for facial pores, five demonstrated moderate clinical improvements of 26% to 50% and three demonstrated improvements of 76% to 100%. Side effects, including pain, post-treatment erythema, and edema, were resolved within 1 week. We suggest that the FPS may provide a new treatment algorithm in some cases with acne scars and enlarged pores. Considering the lack of placebo-controlled, split-face design of our study, optimized, prospective studies should be conducted to fully assess the efficacy of FPS with dynamic operating mode.

    The unarmoured freshwater dinoflagellate Nusuttodinium (= Gymnodinium) aeruginosum retains a cryptomonad-derived kleptochloroplast and nucleus, the former of which fills the bulk of its cell volume. The paucity of studies following morphological changes to the kleptochloroplast with time make it unclear how the kleptochloroplast enlarges and why the cell ultimately loses the cryptomonad nucleus. We observed, both at the light and electron microscope level, morphological changes to the kleptochloroplast incurred by the enlargement process under culture conditions. The distribution of the cryptomonad nucleus after host cell division was also investigated. The volume of the kleptochloroplast increased more than 20-fold, within 120h of ingestion of the cryptomonad. Host cell division was not preceded by cryptomonad karyokinesis so that only one of the daughter cells inherited a cryptomonad nucleus. The fate of all daughter cells originating from a single cell through five generations was closely monitored, and this observation revealed that the cell that inherited the cryptomonad nucleus consistently possessed the largest kleptochloroplast for that generation. Therefore, this study suggests that some important cryptomonad nucleus division mechanism is lost during ingestion process, and that the cryptomonad nucleus carries important information for the enlargement of the kleptochloroplast.

    2018-01-01

    Full Text Available Epithelioid hemangioendothelioma (EHE is a rare vascular neoplasm with variable malignant potential that most often presents within the liver. Many patients present with bilobar or extrahepatic disease, and the current treatment paradigm involves liver transplantation, with favorable long term results. Up to 25% of patients are diagnosed incidentally following imaging for other indications, and confirmation of diagnosis requires histologic analysis, as there are no classical imaging features to distinguish hepatic EHE (HEHE from other solid hepatic lesions. Here we describe a case of microscopic HEHE that was diagnosed following splenectomy for an enlarging vascular tumor within the spleen. Due to the unexpected diagnosis of EHE within the spleen and coexisting but stable appearing liver hemangiomata, a left hepatic lobectomy was performed. Explant histology revealed benign hemangiomata and diffuse, microscopic HEHE. The patient ultimately underwent liver transplantation. HEHE can be a challenging diagnosis, and this case emphasizes that any enlarging vascular lesion, even within the spleen, should prompt a high index of suspicion for HEHE in the setting of known hemangiomata.

    Global Surface Temperature (GST) is one of the most widely used indicators for climate trend and extreme analyses. A widely used GST dataset is the NOAA merged land-ocean surface temperature dataset known as NOAAGlobalTemp (formerly MLOST). The NOAAGlobalTemp had recently been updated from version 3.5.4 to version 4. The update includes a significant improvement in the ocean surface component (Extended Reconstructed Sea Surface Temperature or ERSST, from version 3b to version 4) which resulted in an increased temperature trends in recent decades. Since then, advancements in both the ocean component (ERSST) and land component (GHCN-Monthly) have been made, including the inclusion of Argo float SSTs and expanded EOT modes in ERSST, and the use of ISTI databank in GHCN-Monthly. In this presentation, we describe the impact of those improvements on the merged global temperature dataset, in terms of global trends and other aspects.

    In patients with huge leiomyoma and with adenomyosis of the uterus, a peculiar area of hypointensity was occasionally observed on postcontrast magnetic resonance (MR) imaging in the dorsal portion of the enlarged uterus near the sacral promontory. We describe the imaging characteristics of these MR findings and correlate them with histopathological findings to examine whether the areas represent specific pathological changes. Ten patients with huge leiomyomas and two with huge adenomyotic lesions whose imaging revealed the hypointensity were enrolled. All had enlarged uteri that extended beyond the sacral promontory. MR findings of the hypointense areas were evaluated and correlated with histopathological findings in 5 patients with leiomyoma and two with adenomyosis who had hysterectomy. The ten patients with leiomyoma showed flare-shaped hypointensity arising from the dorsal surface of the uterine body that extended deep into the tumor. The base of the hypointense areas was narrow in 5 patients with intramural leiomyoma and broad in five with subserosal leiomyoma. Two patients with adenomyosis showed nodular-shaped areas of hypointensity in front of the sacral promontory. Precontrast T 1 - and T 2 -weighted MR images showed no signal abnormalities in the portions corresponding to the hypointensity in any of the 12 patients. Pathological examinations showed no specific findings in the portions corresponding to the hypointensity in the 7 patients who had hysterectomy. The areas of hypointensity may represent functional changes, such as decreased localized blood flow caused by compression of the sacral promontory. (author)

  4. Coil embolization of an enlarging fusiform myxomatous cerebral aneurysm

    Frances Lazarow, MD

    2018-04-01

    Full Text Available Myxomatous cerebral aneurysms are rare sequelae of cardiac atrial myxoma. These aneurysms are generally fusiform, multiple, and distal. Pathogenesis and evolution of these aneurysms is still debated. There are currently no guidelines on the management of aneurysms secondary to atrial myxoma. We present a case of a 52-year-old man with multiple fusiform aneurysms 3 years after resection of a left atrial myxoma. One of these aneurysms was followed with cerebral angiography and showed substantial interval enlargement. This aneurysm was subsequently embolized. All aneurysms were stable 6 months post-embolization. Keywords: Myxomatous aneurysm, Fusiform, Coil embolization

    2013-05-01

    Full Text Available The paper answers at two important questions: Is the EU able to support new adhering processes? and Is the Euro area able to enlarge in 2014? The comparative analysis in the paper covers four economic competitors: EU, USA, China and Japan, and is based on GDP growth rate, unemployment and inflation rates. The second part of the paper deals with an economic forecast during 2015-2016, focused on EU27, Euro area, Croatia and Latvia, in order to discuss the effects of the adhering to EU and Euro area. The results of the two-level analysis are supported by pertinent diagrams and annexes. The analysis uses a neutral statistical database – Eurostat – and dedicated forecast software. The main conclusion of the paper is that the adhering processes from 2013 and 2014 are based on economic and political criteria.

    Desjardins, M. L.

    1994-01-01

    GEMPAK is a general meteorological software package developed at NASA/Goddard Space Flight Center. It includes programs to analyze and display surface, upper-air, and gridded data, including model output. There are very general programs to list, edit, and plot data on maps, to display profiles and time series, to draw and fill contours, to draw streamlines, to plot symbols for clouds, sky cover, and pressure tendency, and draw cross sections in the case of gridded data and sounding data. In addition, there are Barnes objective analysis programs to grid surface and upper-air data. The programs include the capabilities to derive meteorological parameters from those found in the dataset, to perform vertical interpolations of sounding data to different coordinate systems, and to compute an extensive set of gridded diagnostic quantities by specifying various nested combinations of scalars and vector arithmetic, algebraic, and differential operators. The GEMPAK 5.1 graphics/transformation subsystem, GEMPLT, provides device-independent graphics. GEMPLT also has the capability to display output in a variety of map projections or overlaid on satellite imagery. GEMPAK 5.1 is written in FORTRAN 77 and C-language and has been implemented on VAX computers under VMS and on computers running the UNIX operating system. During installation and normal use, this package occupies approximately 100Mb of hard disk space. The UNIX version of GEMPAK includes drivers for several graphic output systems including MIT's X Window System (X11,R4), Sun GKS, PostScript (color and monochrome), Silicon Graphics, and others. The VMS version of GEMPAK also includes drivers for several graphic output systems including PostScript (color and monochrome). The VMS version is delivered with the object code for the Transportable Applications Environment (TAE) program, version 4.1 which serves as a user interface. A color monitor is recommended for displaying maps on video display devices. Data for rendering

  8. [Enlargement in managment of lumbar spinal stenosis].

    Science.gov (United States)

    Steib, J P; Averous, C; Brinckert, D; Lang, G

    1996-05-01

    Lumbar stenosis has been well discussed recently, especially at the 64th French Orthopaedic Society (SOFCOT: July 1989). The results of different surgical treatments were considered as good, but the indications for surgical treatment were not clear cut. Laminectomy is not the only treatment of spinal stenosis. Laminectomy is an approach with its own rate of complications (dural tear, fibrosis, instability... ).Eight years ago, J. Sénégas described what he called the "recalibrage" (enlargement). His feeling was that, in the spinal canal, we can find two different AP diameters. The first one is a fixed constitutional AP diameter (FCAPD) at the cephalic part of the lamina. The second one is a mobile constitutional AP diameter (MCAPD) marked by the disc and the ligamentum flavum. This diameter is maximal in flexion, minimal in extension. The nerve root proceeds through the lateral part of the canal: first above, between the disc and the superior articular process, then below, in the lateral recess bordered by the pedicle, the vertebral body and the posterior articulation. With the degenerative change the disc space becomes shorter, the superior articular process is worn out with osteophytes. These degenerative events are complicated by inter vertebral instability increasing the stenosis. The idea of the "recalibrage" is to remove only the upper part of the lamina with the ligamentum flavum and to cut the hypertrophied anterior part of the articular process from inside. If needed the disc and other osteophytes are removed. The surgery is finished with a ligamentoplasty reducing the flexion and preventing the extension by a posterior wedge.Our experience in spine surgery especially in scoliosis surgery, showed us that it was possible to cure a radicular compression without opening the canal. The compression is then lifted by the 3D reduction and restoration of an anatomy as normal as possible. Lumbar stenosis is the consequence of a degenerative process. Indeed, hip

    An epidemic of foot-and-mouth disease (FMD) in a FMD-free country with large exports of livestock and livestock products would result in profound economic damage. This could be reduced by rapid and efficient control of the disease spread. The objectives of this study were to estimate the economic...... impact of a hypothetical FMD outbreak in Denmark based on changes to the economic assumptions of the model, and to investigate whether the control of an FMD epidemic can be improved by combining the enlargement of protection or surveillance zones with pre-emptive depopulation or emergency vaccination....... The stochastic spatial simulation model DTU-DADS was used to simulate the spread of FMD in Denmark. The control strategies were the basic EU and Danish strategy, pre-emptive depopulation, suppressive or protective vaccination, enlarging protection or surveillance zones, and a combination of pre...

  10. Acinar cell carcinoma of the pancreas presenting as diffuse pancreatic enlargement: Two case reports and literature review.

    2017-09-01

    Pancreatic acinar cell carcinoma (ACC) is a rare malignant tumor of exocrine pancreas. It is typically a well-marginated large solid mass arising in a certain aspect of the pancreas. Diffuse involvement of ACC in the pancreas is very rare, and may simulate pancreatitis in radiological findings. We report 2 cases of ACC presenting as diffuse enlargement of the pancreas due to tumor involvement without formation of a distinct mass. The patients consisted of a 41-year-old man with weight loss and a 77-year-old man who was asymptomatic. Computed tomography (CT) and 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT showed diffuse enlargement of the pancreas forming a sausage-like shape with homogenously increased FDG activity. Endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA) biopsy of the pancreatic lesion was performed. Histopathology results from the pancreas confirmed the diagnosis of pancreatic ACC. Because diffuse enlargement of the pancreas is a common imaging feature of pancreatitis, recognition of this rare morphologic pattern of ACC is important for radiological diagnosis of this tumor.

  11. Emotional stimuli-provoked seizures potentially misdiagnosed as psychogenic non-epileptic attacks: A case of temporal lobe epilepsy with amygdala enlargement

    Directory of Open Access Journals (Sweden)

    Hidetaka Tamune

    Full Text Available The association between emotional stimuli and temporal lobe epilepsy (TLE is largely unknown. Here, we report the case of a depressed, 50-year-old female complaining of episodes of a “spaced out” experience precipitated by emotional stimuli. Psychogenic non-epileptic attacks were suspected. However, video-EEG coupled with emotional stimuli-provoked procedures and MRI findings of amygdala enlargement, led to the diagnosis of left TLE. Accurate diagnosis and explanation improved her subjective depression and seizure frequency. This case demonstrated that emotional stimuli can provoke seizures in TLE and suggested the involvement of the enlarged amygdala and the modulation of emotion-related neural circuits.

    1975-01-01

    1 - Description of problem or function: PLOT-3D is a package of sub- programs designed to draw three-dimensional surfaces from arrays of points (x,y,z). The surfaces can be drawn after arbitrary rotations about the three coordinate axes. 2 - Method of solution: PLOT-3D is a computer program to plot any surface for which each coordinate pair (x,y) is associated with a unique z in the set of points (x,y,z). It uses matrix transformation of the points to generate different views of the surface after arbitrary rotations about the three coordinate axes. Four versions of PLOT-3D are available. Output of version 1 and 3 is by film recorder. Output of version 2 and 4 is by CalComp plotter. Versions 3 and 4 do not draw lines which would be invisible to a viewer looking at an opaque surface, whereas versions 1 and 2 draw every line on the surface. 3 - Restrictions on the complexity of the problem: Versions 3 and 4 limit number of rows in arrays (x,y,z) to 100 and also number of columns in arrays (x,y,z) to 100

    The aim of this randomized, controlled, prospective clinical study was to determine if foraminal enlargement instrumentation during endodontic treatment is associated with more postoperative pain compared with standard nonenlargement instrumentation. Forty volunteers with a single root canal were diagnosed with asymptomatic necrosis with apical periodontitis and randomized into 2 experimental groups (ie, the control group and the foraminal enlargement group). Endodontic treatment was performed in a single visit, and volunteers were instructed to record pain intensity (ie, none, slight, moderate, and severe). Scores from 1 to 4 were attributed to each kind of pain after 12, 24, and 48 hours. The Kolmogorov-Smirnov and Student's t tests were used to determine significant differences at P .05, Student's t test). Postoperative pain showed no statistically significant difference between the groups at any observation period (P > .05). Also, no significant difference was observed in the mean number of analgesic tablets used between the groups (P > .05). The foraminal enlargement and nonenlargement techniques resulted in the same postoperative pain and necessity for analgesic medication. This may suggest that the use of foraminal enlargement should be performed for endodontic treatment previsibility without increasing postoperative pain.

    The objective of this study was to examine measurements of the vestibular aqueduct on axial CT figures and to examine the cases with borderline EVA. The width of the vestibular aqueduct was measured in two places, the midpoint of the duct and the external aperture in the posterior cranial fossa. Criteria was as follow: Enlargement; ≥1.5 mm at the midpoint, ≥2 mm at the aperture, Borderline; 1-1.4 mm at the midpoint, 1.5-1.9 mm at the aperture. Three hundred forty-five cases with CT scans of the temporal bones taken during July 2003 to June 2004 in the secondary ENT referral center. Those patients include sensorinearal, mixed or conductive deafness, vertigo, ear infections and other ear diseases. Enlarged vestibular aqueduct was found in 10 ears with sensorineural deafness (SD) and 2 ears without SD. Borderline measurements were found in 19 ears with SD and 33 ears without SD. The enlarged midpoint measurement was not seen in the cases without SD. More than 1.5 mm of the definition for the enlargement at the midpoint of the vestibular aqueduct seemed to be appropriate in the clinical situation. The measurement at the midpoint of the duct is more reliable than at the external aperture. The conductive component in EVA Syndrome with mixed hearing loss is present only at the lower frequencies (250, 500 Hz), not at the middle and higer frequencies. Long-term follow-up of hearing should be done in the borderline cases with check-up of PDS gene anomaly if necessary. (author)

  16. Bronchial compression by an enlarged left atrium in infants; a cause of hypovascularity of the left lung

    In three infants seen recently at our institution we noted signs of compression of the left main bronchus associated with enlarged left atria. None of our cases demonstrated the more usual signs of hyperinflation which are a hyperlucent lung field, depressed hemidiaphragm and mediastinal shift away from the affected side. In addition, hypoperfusion of the left lung was noted in each case. We believe that bronchial compression due to an enlarged left atrium, with consequent hypoxic vasoconstriction is a clinically significant entity, which is not well described and may be unappreciated in infants in whom the typical signs of hyperinflation are absent.

    To introduce efficient stereological approaches for estimating the volume of a normal or enlarged spleen from MDCT. All study participants underwent an abdominal MDCT. The first group included 20 consecutive patients with splenomegaly and the second group consisted of 20 subjects with a normal spleen. Splenic volume estimations were performed using the stereological point counting method. Stereological assessments were optimized using the systematic slice sampling procedure. Planimetric measurements based on manual tracing of splenic boundaries on each slice were taken as reference values. Stereological analysis using five to eight systematically sampled slices provided enlarged splenic volume estimations with a mean precision of 4.9 ± 1.0 % in a mean time of 2.3 ± 0.4 min. A similar measurement duration and error was observed for normal splenic volume assessment using four to seven systematically selected slices. These stereological approaches slightly but insignificantly overestimated the volume of a normal and enlarged spleen compared to planimetry (P > 0.05) with a mean difference of -1.3 ± 4.3 % and -2.7 ± 5.2 %, respectively. The two methods were highly correlated (r ≥ 0.96). The variability of repeated stereological estimations was below 3.8 %. The proposed stereological approaches enable the rapid, reproducible, and accurate splenic volume estimation from MDCT data in patients with or without splenomegaly. (orig.)

    Full Text Available Background: Epilepsy is a gathering of neurological disorders characterized by epileptic seizures. Epileptic children, who are on active treatment with antiepileptic drugs, have a well-recognized side effect of gingival enlargement. Therefore, all efforts should be made, particularly for the population who are diagnosed or affected by the systemic disease. This study was conducted with an aim to determine oral hygiene status and gingival enlargement among epileptic and healthy children as related to various antiepileptic drugs. Materials and Methods: The cross-sectional observational study was conducted in the department of pedodontics and attached general hospital. A sample size of 120 participants with 60 healthy and 60 epileptic children between age 2 and 14 years were included. Oral health status of participants was examined using oral hygiene simplified index and plaque index. Gingival enlargement was assessed using Miranda–Brunet index. For statistical analysis, one-way ANOVA test, independent t-test, and Pearson's Chi-square test were used. Results: From the total participants included in the study, 49% of participants had good oral hygiene from healthy group, and 28% participants had poor oral hygiene from the epileptic group. Sodium valproate was the most common drug used and was associated with increased gingival enlargement. Conclusion: Conclusion can be drawn that epileptic children under medication had poor oral hygiene and an increased risk for gingival enlargement as compared to their healthy counterparts. It must be stressed that the epileptic patients should be given dental care without conditions and provided with best possible care to restore esthetics and functions.

    To determine the prognostic value of outer retinal tubulation (ORT) in the enlargement amount of geographic atrophy (GA) in eyes with age-related macular degeneration (AMD). Cohort study. One hundred eight fellow untreated eyes of 143 patients with GA resulting from AMD enrolled in the MAHALO study (clinicaltrials.gov identifier, NCT01229215) who completely satisfied the study term and had gradable spectral-domain optical coherence tomography (OCT) images obtained at both baseline and month 18 visits. The MAHALO study enrolled 143 subjects into a phase 1b/2 multicenter, randomized, single-masked, sham-injection controlled clinical trial of the safety, tolerability, and evidence of activity of lampalizumab in patients with GA associated with AMD. Spectral-domain optical coherence tomography images were obtained at multiple time points in both eyes, although only the baseline and month 18 data of the fellow (nonstudy) eyes were considered in this exploratory analysis. The Cirrus HD-OCT review software was used for automatic segmentation and measurement of GA areas, with manual correction of segmentation errors by certified OCT graders. Baseline OCT images also were assessed for the presence of ORT. The enlargement amount of GA in eyes with ORT was compared with that of eyes without ORT. Comparison of the enlargement amount of GA in eyes with and without ORT. Twenty-four of these 108 eyes demonstrated evidence of ORT. The amount of enlargement of GA in eyes with ORT was significantly slower than that of eyes without ORT (1.85±0.78 vs. 2.67±1.61; P = 0.001). This difference remained significant when considering subgroups with unifocal or multifocal GA lesions, because eyes with ORT in both subgroups had a slower enlargement amount of GA than eyes without ORT (2.91±1.70 vs. 2.08±0.88 [P = 0.01], in eyes with multifocal GA lesions; and 2.24±1.40 vs. 1.63±0.57 [P = 0.02], in eyes with unifocal GA lesions). In eyes with ORT, GA lesions seem to enlarge at a

    An instance of isolated unilateral temporalis muscle hypertrophy (reactive masticatory muscle hypertrophy with fiber type 1 predominance) confirmed by muscle biopsy with histochemical fiber typing and image analysis in a 62 year-old man is reported. The patient presented with bruxism and a painful swelling of the temple. Absence of asymmetry or other abnormalities of the craniofacial skeleton was confirmed by magnetic resonance imaging and cephalometric analyses. The patient achieved symptomatic improvement only after undergoing botulinum toxin injections. Muscle biopsy is key in the diagnosis of reactive masticatory muscle hypertrophy and its distinction from masticatory muscle myopathy (hypertrophic branchial myopathy) and other non-reactive causes of painful asymmetric temporalis muscle enlargement.

  4. Northern Steps of EU Enlargement: The Impact of “Cohesion” Policies on Iceland’s Accession Process

    Directory of Open Access Journals (Sweden)

    Adriana Di Stefano

    2011-03-01

    Full Text Available This paper focuses on the EU accession process of Iceland, reading the latest northern steps of EU enlargement under a “cohesion” perspective, i.e., through the lens of the cohesion “theory”, namely the method resulting from interactions of the general principles of subsidiarity and cooperation or partnership. From the Mediterranean to the Arctic, the territorial dimension of cohesion policies, as grounded in different EU policies, plays different roles and meets a wide range of economic and social needs. By implementing Nordicum-Mediterraneum analogies, a cohesion-minded EU enlargement approach requires the overall reframing of territorial-based policies and a better allocation of shared responsibilities at the more efficient level of governance.

    Hidradenitis suppurativa is a chronic, recurrent inflammatory disease affecting the cutaneous apocrine glands and resulting in their obstruction. This enigmatic disease causes recurrent episodes of infection, edema, scarring, and fibrosis of surrounding tissues. We present the case of a 55-year-old man with two decades of inguinal hidradenitis suppurativa that resulted in extensive penile subcutaneous lymphedema and enlargement secondary to scarring and obstructive lymphadenopathy. Reconstructive phalloplasty to restore normal penile function was required. Minimal recurrent induration, normal cutaneous sensation, and normal voiding and erectile function were noted at 3 years of follow-up.

  7. CONNECTING THE ENLARGEMENT PROCESS WITH THE EUROPEANIZATION THEORY (THE CASE OF TURKEY

    Directory of Open Access Journals (Sweden)

    Teodor Lucian Moga

    2010-03-01

    Full Text Available Europeanization is one of the theoretical instruments which had a vital influence on candidate countries for EU membership. Due to its aspirations of becoming member of the European Union (EU and in its attempt to fulfil the Copenhagen criteria, Turkey is trying to comply with the EU acquis communautaire. The aim of this paper is to assess the effects of the Europeanization process on the countries subject to EU enlargement strategy, with a special focus on Turkey, particularly since the country received the EU candidate status in 1999. This paper has been organized in the following way: firstly, it points out how both the traditional Europeanization and the enlargement led Europeanization have been depicted in the work of several important scholars; secondly, by offering a short overview of Turkey’s foreign relations vis-à-vis its neighbourhood, especially in the last decade, it examines how the mechanism of Europeanization largely influenced the country’s diplomatic culture. Traditionally, Turkey has been attuned to hard security issues and architectures. However, the Turkish foreign policy strategy emphasised in thepast years the Venus side of things in many settings in line with EU requirements.

    2005-06-01

    The present report is a background report describing the meteorological conditions and the modelling of surface hydrology and near-surface hydrogeology in support of the Forsmark version 1.2 SDM based on the data available in the Forsmark 1.2 ''data freeze'' (July 31, 2004). The area covered in the conceptual and descriptive modelling is characterised by a low relief and a small-scale topography. Almost the whole area is located below 20 m a s l (metres above sea level). The corrected mean annual precipitation is 600-650 mm and the mean annual evapotranspiration can be estimated to a little more than 400 mm, leaving approximately 200 mm x year-1 for runoff. Till is the dominating Quaternary deposit covering approximately 75% of the area. In most of the area, the till is sandy. Bedrock outcrops are frequent but cover only approximately 5% of the area. Direct groundwater recharge from precipitation is the dominant source of groundwater recharge. The small-scale topography implies that many local, shallow groundwater flow systems are formed in the Quaternary deposits, overlaying more large-scale flow systems associated with groundwater flows at greater depths. Groundwater level time series from wells in till and bedrock within the same areas show a considerably higher groundwater level in the till than in the bedrock. The sediment stratigraphy of lakes and wetlands is crucial for their function as discharge areas for groundwater. Comparisons between measured lake water levels and groundwater levels below and around lakes indicate that the lakes in some cases may act as sources of groundwater recharge. Specifically, observations from Lake Bolundsfjaerden and Lake Eckarfjaerden show that such conditions were at hand during the dry summer of 2003. However, whether the observed water level relations correspond to significant water fluxes depends also on the hydrogeological properties of the lake sediments and the underlying Quaternary deposits.

    A research project is underway at NASA Glenn to produce a computer code which can accurately predict ice growth under a wide range of meteorological conditions for any aircraft surface. This report will present a description of the code inputs and outputs from version 3.2 of this software, which is called LEWICE. This version differs from release 2.0 due to the addition of advanced thermal analysis capabilities for de-icing and anti-icing applications using electrothermal heaters or bleed air applications, the addition of automated Navier-Stokes analysis, an empirical model for supercooled large droplets (SLD) and a pneumatic boot option. An extensive effort was also undertaken to compare the results against the database of electrothermal results which have been generated in the NASA Glenn Icing Research Tunnel (IRT) as was performed for the validation effort for version 2.0. This report will primarily describe the features of the software related to the use of the program. Appendix A has been included to list some of the inner workings of the software or the physical models used. This information is also available in the form of several unpublished documents internal to NASA. This report is intended as a replacement for all previous user manuals of LEWICE. In addition to describing the changes and improvements made for this version, information from previous manuals may be duplicated so that the user will not need to consult previous manuals to use this software.

  10. Challenges to NATO’s Fifth Enlargement Round: Turkey’s Attitude towards Romanian’s Admission

    Full Text Available The relations between Romania – the only Latin nation in Balkan Peninsula, in a broader sense – and Turkey has a long history, which is traced back to the Ottoman period. These relations were relatively ceased during the Cold War. After the collapse of Soviet Union, a new era started for Turkish-Romanian relations. During the WWI, Tsarist Russia forced Romania to be its ally, in order to besiege Germany from South, and also to threat Austria. Its aim was intended to direct the Central Powers’ attacks to the Balkans, in order to keep the warfare away from the front lines and from the Russian heartland. Following the Tsarist pan-Slavist policy, the Bolshevist Russia designated Balkans territories as vital for its security and defence. At the first opportunity emerged after the WWII, Stalin had included those lands behind the Iron Curtain area. After a fairly lengthy period under the Iron Curtain, after 1989, Romania like other eastern European countries achieved its freedom, but post-Cold War attitude of Russia towards the Balkans has remained unchanged. This paper seeks to explore the post-Cold War policies of NATO and the Turkey’s attitude towards the enlargements of alliance. It focuses on the fifth round of enlargement, when Romania and other six Balkans and Baltic countries were invited to join the North Atlantic Alliance. In addition, it will insist on the role of Turkey in the enlargement process, and its firm support for Romania's accession to NATO.

  11. Laboratory determination of normal operating flow rates with enlarged outlet fittings -- BDF reactors

    Experiments have been conducted in the Hydraulics Laboratory, at the request of IPD`s Mechanical Development-A Operation, to determine the energy losses of various enlarged outlet fitting combinations. These experiments were conducted an steady state runs and allow the determination of the normal operating point (flow rate) of a reactor process channel under selected conditions of front header pressure and fuel charge. No attempt is made to make a mechanical or economic evaluation of the particular fitting combinations, although observations were noted which might bear on this evaluation. It is very important for the reader to bear in mind that changing outlet fittings will definitely affect the reactor tube power limits and outlet vater temperature limits. The size of the outlet fittings largely determines the present outlet temperature limits of the old reactors. The flow characteristics of these present fittings cause some degree of pressurization to suppress boiling on the fuel charge and also cause dual Panellit trip protection for certain flow changes and for power surges. Enlargement of the outlet fittings may actually reduce the allowable outlet coolant temperature limits. Since these effects cannot be determined on the apparatus used in these experiments, a complete discussion of this point is not included in this report. However, the seriousness of these effects should be known and carefully analyzed before a final selection of enlarged outlet fittings in made. This report will be one of a series. New reports in the series will be issued as data are obtained for other such outlet fitting combinations or for new concepts of outlet fitting assemblies such as the new nozzle being developed by C. E. Trantz for use on F-reactor stuck gunbarrel tubes.

  12. Subsidy policy and the enlargement of choice

    2009-01-01

    Development is the enlargement of people's choices. Optimal subsidy policy is intended to create the right incentives for each of the value chain participants. This paper contends that the interest subsidy offered by the Indian federal Ministry of New and Renewable Energy for solar thermal systems, through mainstream banking channels is superior in intent and outcome compared to the capital subsidy as currently offered for solar PV systems, routed through government controlled delivery channels. The interest subsidy enhances innovation, improves service delivery and expands the range of product available to consumers enjoying a wide range of endowments, thus leading to more inclusive development. The simple monopoly model developed by Atkinson [Atkinson AB. Capabilities, exclusion and the supply of goods. In: Basu K, Pattanaik P, Suzumura K, editor, Choice, Welfare and Development. Oxford University Press; 1995] is applied to the context of solar home systems to demonstrate price reduction and choice expansion in a liberalized market, facilitated by an interest subsidy scheme.

    1994-01-01

    GEMPAK is a general meteorological software package developed at NASA/Goddard Space Flight Center. It includes programs to analyze and display surface, upper-air, and gridded data, including model output. There are very general programs to list, edit, and plot data on maps, to display profiles and time series, to draw and fill contours, to draw streamlines, to plot symbols for clouds, sky cover, and pressure tendency, and draw cross sections in the case of gridded data and sounding data. In addition, there are Barnes objective analysis programs to grid surface and upper-air data. The programs include the capabilities to derive meteorological parameters from those found in the dataset, to perform vertical interpolations of sounding data to different coordinate systems, and to compute an extensive set of gridded diagnostic quantities by specifying various nested combinations of scalars and vector arithmetic, algebraic, and differential operators. The GEMPAK 5.1 graphics/transformation subsystem, GEMPLT, provides device-independent graphics. GEMPLT also has the capability to display output in a variety of map projections or overlaid on satellite imagery. GEMPAK 5.1 is written in FORTRAN 77 and C-language and has been implemented on VAX computers under VMS and on computers running the UNIX operating system. During installation and normal use, this package occupies approximately 100Mb of hard disk space. The UNIX version of GEMPAK includes drivers for several graphic output systems including MIT's X Window System (X11,R4), Sun GKS, PostScript (color and monochrome), Silicon Graphics, and others. The VMS version of GEMPAK also includes drivers for several graphic output systems including PostScript (color and monochrome). The VMS version is delivered with the object code for the Transportable Applications Environment (TAE) program, version 4.1 which serves as a user interface. A color monitor is recommended for displaying maps on video display devices. Data for rendering

    2012-01-01

    Background Given the relative abundance and toxic potential of acrolein in inhaled cigarette smoke, it is surprising how little is known about the pulmonary and systemic effects of acrolein. Here we test the hypothesis whether systemic administration of acrolein could cause endoplasmic reticulum (ER) stress, and lung cell apoptosis, leading to the enlargement of the alveolar air spaces in rats. Methods Acute and chronic effects of intraperitoneally administered acrolein were tested. Mean alveolar airspace area was measured by using light microscopy and imaging system software. TUNEL staining and immunohistochemistry (IHC) for active caspase 3 and Western blot analysis for active caspase 3, and caspase 12 were performed to detect apoptosis. The ER-stress related gene expression in the lungs was determined by Quantitative real-time PCR analysis. Acrolein-protein adducts in the lung tissue were detected by IHC. Results Acute administration of acrolein caused a significant elevation of activated caspase 3, upregulation of VEGF expression and induced ER stress proteins in the lung tissue. The chronic administration of acrolein in rats led to emphysematous lung tissue remodeling. TUNEL staining and IHC for cleaved caspase 3 showed a large number of apoptotic septal cells in the acrolein-treated rat lungs. Chronic acrolein administration cause the endoplasmic reticulum stress response manifested by significant upregulation of ATF4, CHOP and GADd34 expression. In smokers with COPD there was a considerable accumulation of acrolein-protein adducts in the inflammatory, airway and vascular cells. Conclusions Systemic administration of acrolein causes endoplasmic reticulum stress response, lung cell apoptosis, and chronic administration leads to the enlargement of the alveolar air spaces and emphysema in rats. The substantial accumulation of acrolein-protein adducts in the lungs of COPD patients suggest a role of acrolein in the pathogenesis of emphysema. PMID:22675432

    The goal of this study is a comprehensive examination of openings discovered on two skulls in the collection of skeletal remains from the Loyalty Islands (Melanesia). The skull No. 1524 displayed an evidence of successful trepanation, and the skull No. 7985 revealed openings that were reminiscent of a trepanation, however, we are inclined to believe that in the latter case we are dealing with a rare genetic anomaly - enlarged parietal foramen.

    The superior cervical sympathetic ganglion, the largest and most cranial of the three cervical sympathetic ganglia, transfers sympathetic signals to specific targets on the head and neck. This ganglion is located just lateral to the retropharyngeal space along the medial margin of the carotid sheath. Located thus, an enlarged superior cervical sympathetic ganglion can mimic a metastatic lymph node in the retropharyngeal space of the suprahyoid neck in head and neck cancer patients. However, this is often disregarded by radiologists due to lack of interest in its anatomic location. We present a case of an enlarged superior cervical sympathetic ganglion mimicking a retropharyngeal metastatic lymph node in a 42-year-old man with oral tongue cancer.

    Full Text Available „Epilepsy” refers to a group of neurological disorders characterized by chronic, recurrent, paroxysmal seizure activity. Nocturnal frontal lobe epilepsy is a neurological disorder characterized by brief, recurring seizures produ‑ ced in the frontal lobes of the brain, often while the patient is sleeping, and also by clusters of brief motor seizures. Seizure disorders may affect the dental status and oral health of patients. Epileptic drugs lead to gingival hyper‑ plasia, namely tissue enlargement, caused by an increased number of cells.

Malignant enlargements must be differentiated from benign enlargements for adequate treatment of each patient. High serum total prostate-specific antigen (tPSA levels suggest malignancy, but some of the biopsies done due to a serum tPSA value >4 ng/mL would be negative for malignancy because of the low specificity of tPSA for prostate cancer. This study aims to compare the histologic findings of all prostate specimens obtained from core needle biopsy, open simple prostatectomy, and transurethral resection of the prostate with the respective serum tPSA values in an attempt to decipher the role of serum tPSA in the management of these patients.Methods: The case notes of patients attended to from April 2009 to March 2012 were analyzed. Essentially, the age of the patient, findings on digital rectal examination, abdominopelvic ultrasonography report on the prostate, serum tPSA, and histology reports from biopsy or prostatectomy specimens as indicated were extracted for analysis.Results: The relationship between age, findings on digital rectal examination, serum tPSA, abdominopelvic ultrasonography report, and histology are compared. A statistically significant relationship existed between a malignant histology and age 65 years and older, suspicious findings on digital rectal examination, suspicious ultrasonography findings, and serum tPSA >10 ng/mL, but not tPSA >4 ng/mL.Conclusion: In Nigerian patients with symptomatic prostate enlargement, serum tPSA should be seen as a continuum with increasing risk of prostate malignancy

    To validate the Spanish version of the Emotional Labour Scale (ELS), an instrument widely used to understand how professionals working with people face emotional labor in their daily job. An observational, cross-sectional and multicenter survey was used. Nursing students and their clinical tutors (n=211) completed the self-reported ELS when the clinical practice period was over. First order and second order Confirmatory Factor Analyses (CFA) were estimated in order to test the factor structure of the scale. The results of the CFA confirm a factor structure of the scale with six first order factors (duration, frequency, intensity, variety, surface acting and deep acting) and two larger second order factors named Demands (duration, frequency, intensity and variety) and Acting (surface acting and deep acting) establishing the validity of the Spanish version of the ELS.

  6. Cryptococcus neoformans capsular enlargement and cellular gigantism during Galleria mellonella infection.

    Directory of Open Access Journals (Sweden)

    Rocío García-Rodas

    Full Text Available We have studied infection of Cryptococcus neoformans in the non-vertebrate host Galleria mellonella with particular interest in the morphological response of the yeast. Inoculation of C. neoformans in caterpillars induced a capsule-independent increase in haemocyte density 2 h after infection. C. neoformans manifested a significant increase in capsule size after inoculation into the caterpillar. The magnitude of capsule increase depended on the temperature, being more pronounced at 37°C than at 30°C, which correlated with an increased virulence of the fungus and reduced phagocytosis at 37°C. Capsule enlargement impaired phagocytosis by haemocytes. Incubation of the yeast in G. mellonella extracts also resulted in capsule enlargement, with the polar lipidic fraction having a prominent role in this effect. During infection, the capsule decreased in permeability. A low proportion of the cells (<5% recovered from caterpillars measured more than 30 µm and were considered giant cells. Giant cells recovered from mice were able to kill the caterpillars in a manner similar to regular cells obtained from in vivo or grown in vitro, establishing their capacity to cause disease. Our results indicate that the morphological transitions exhibited by C. neoformans in mammals also occur in a non-vertebrate host system. The similarities in morphological transitions observed in different animal hosts and in their triggers are consistent with the hypothesis that the cell body and capsular responses represent an adaptation of environmental survival strategies to pathogenesis.

    We calculate the NS-R fermionic zero-norm states of the type II string spectrum. The massless and some possible massive zero-norm states are seen to be responsible for the space-time supersymmetry. The existence of other fermionic massive zero-norm states with higher spinor-tensor indices correspond to new enlarged boson-fermion symmetries of the theory at high energy. We also discuss the R-R charges and R-R zero-norm states and justify the idea that the perturbative string does not carry the massless R-R charges. (orig.)

  10. Liberalization and enlargement: effects of the industrial organisation of natural gas markets in Eastern Europe

    2005-01-01

    After half a century of political division within the European continent, and of State control over national energy industries, a new industrial and political organisation model aiming at creating a single natural gas market tends to emerge currently within the enlarged European Union. Yet new member countries are former centrally planned, socialist economies, with very different industrial structures for natural gas. However, those countries should adjust to the institutional framework applicable in the European Union, including bringing their gas industries into compliance with the liberalization process that old member countries initiated years ago. In that unprecedented context, one basic issue is whether the gas industry liberalization, in the framework of the enlargement, will have expected results in terms of competition, efficiency and profits for Eastern countries, whether new members or candidates for membership. The objective of the research work behind this article was to analyse the effects of that complex trend on the industrial organisation of gas markets in eastern Europe. (author)

    Poor tumor perfusion and unfavorable vessel permeability compromise nanomedicine drug delivery to tumors. Captopril dilates blood vessels, reducing blood pressure clinically and bradykinin, as the downstream signaling moiety of captopril, is capable of dilating blood vessels and effectively increasing vessel permeability. The hypothesis behind this study was that captopril can dilate tumor blood vessels, improving tumor perfusion and simultaneously enlarge the endothelial gaps of tumor vessels, therefore enhancing nanomedicine drug delivery for tumor therapy. Using the U87 tumor xenograft with abundant blood vessels as the tumor model, tumor perfusion experiments were carried out using laser Doppler imaging and lectin-labeling experiments. A single treatment of captopril at a dose of 100 mg/kg significantly increased the percentage of functional vessels in tumor tissues and improved tumor blood perfusion. Scanning electron microscopy of tumor vessels also indicated that the endothelial gaps of tumor vessels were enlarged after captopril treatment. Immunofluorescence-staining of tumor slices demonstrated that captopril significantly increased bradykinin expression, possibly explaining tumor perfusion improvements and endothelial gap enlargement. Additionally, imaging in vivo, imaging ex vivo and nanoparticle distribution in tumor slices indicated that after a single treatment with captopril, the accumulation of 115-nm nanoparticles in tumors had increased 2.81-fold with a more homogeneous distribution pattern in comparison to non-captopril treated controls. Finally, pharmacodynamics experiments demonstrated that captopril combined with paclitaxel-loaded nanoparticles resulted in the greatest tumor shrinkage and the most extensive necrosis in tumor tissues among all treatment groups. Taken together, the data from the present study suggest a novel strategy for improving tumor perfusion and enlarging blood vessel permeability simultaneously in order to improve

The aim of this study was to compare the efficacy of shape-modified partially covered self-expandable metal stent (SEMS that has enlarged head versus uncovered SEMS for palliation of gastric outlet obstruction (GOO. Methods. A total of 48 patients underwent insertion of either enlarged-head SEMS (n=24 or uncovered SEMS (uSEMS (n=24 for palliation of GOO from July 2009 to July 2016. Patients with inoperable or advanced malignancy were included. Technical feasibility and clinical outcomes were compared. Results. Technical success rate was 100% (24/24 and 95.8% (23/24 for enlarged-head SEMS group and uSEMS group, respectively. Clinical success rate was 87.5% (21/24 and 87.0% (20/23 for enlarged-head SEMS group and uSEMS group, respectively. The gastric outlet obstruction scoring system score significantly improved in both groups (p<0.001 for both. Mean survival was similar between the groups: enlarged-head SEMS group, 99.3 days (range, 19–358 days versus uSEMS group, 82.1 days (range, 11–231 days (p=0.418. The mean stent patency also showed no difference between the groups: enlarged-head SEMS group, 87.1 days (range, 8–358 days versus uSEMS group, 60.4 days (range, 2–231 days (p=0.204. With enlarged-head SEMS, distal migration did not occur, but proximal migration was observed in four cases. Conclusions. Distal migration was prevented by shaping the SEMS to have an enlarged head, but improvement in stent patency could not be observed.

    The aim of the present study was to evaluate the clinical results of pars plana vitrectomy (PPV) combined with the surgical enlargement of internal limiting membrane (ILM) peeling in patients who had previously undergone failed idiopathic macular hole (IMH) surgery. In the study, 134 eyes from 130 IMH patients who had received PPV combined with ILM peeling surgery (2 disk diameters) were analyzed. Within this cohort, 14 eyes had IMHs that were not closed, of which 13 eyes underwent a second surgery involving enlargement of the ILM peeling. The extent of the ILM peeling was increased to the vascular arcades of the posterior fundus in the secondary surgery. Of the 13 eyes that underwent secondary surgery, five were in stage III and nine were in stage IV. The second surgery successfully achieved IMH closure in 61.5% (8/13) of the eyes. The IMH was completely closed following surgery and the logMAR vision increased from 0.98 to 0.84 (P=0.013) in the 8 successfully treated cases. The surgical enlargement of ILM peeling closed the IMHs and improved vision in the majority of patients. In addition, the procedures were safe. Therefore, the results of the present study indicate that enlargement of ILM peeling may be an effective therapy for patients who have previously undergone the failed surgical correction of an IMH.

    Highlights: • The spin-crossover nanocrystals were described by modified Ising-like model. • The ligand field on the surface is a function of external fluctuations. • The thermal hysteresis with surface and bulk interactions of the lattice was studied. • The system behavior with fluctuating ligand field on the surface was examined. • The fluctuations enlarge the hysteresis, but smaller surface interaction narrows it. - Abstract: The impact of surface effects on thermal induced spin crossover phenomenon is a subject of a broad and current interest. Using the modified Ising-like model of spin crossover solids with the ligand field as function of the molecule’ positions and random component on surface by means of Metropolis Monte Carlo algorithm the thermal spin transition curves were calculated. The analysis of spin configuration during transition gives a general idea about contribution of molecules from the surface and inside the lattice into resulting magnetization of the systems. The behavior of hysteresis loop for various surface coupling and fluctuations strength has been described.

    Several ventricular segments were first measured linearly on the CT image to determine the normal upper limit in adolescent and mature subjects. On the basis of the values obtained, large ventricules were defined, and discriminant analysis with the increase and decrease of the variable was applied. The error ratio of discrimination between pressure hydrocephalus and cerebral atrophy was 8.4%. The temporal horn and trigone are larger in pressure hydrocephalus than in cerebral atrophy, in which the anterior horn is larger. The error ratio of discrimination between obstructive hydrocephalus and communicating hydrocephalus was 11.3%. The hypothalamic segment of the third ventricle and the body of the lateral ventricle are larger in obstructive hydrocephalus than in communicating hydrocephalus, in which the anterior horn and the cellae mediae at the level of the head of caudate nuclei are relatively large. Enlarged ventricles were divided into three groups with characteristic segment: one with large temporal horn and trigone in pressure hydrocephalus; one with larger hypothalamic segment of the third ventricle and larger body of the lateral ventricle in obstructive hydrocephalus than in communicating hydrocephalus; and relatively large anterior horn, cellae mediae at the level of the head of caudate nuclei, and thalamic segment of the third ventricle in cerebral atrophy and communicating hydrocephalus. These findings contribute to the pathological evaluation of ventricular enlargement. The hypothalamic segment of the third ventricle assumes a round or oval shape in pressure hydrocephalus but a rectangular or teardrop shape in cerebral atrophy. (J.P.N.)

    A variety of treatment modalities have been used to reduce the size of enlarged facial pores without obvious success. To assess and compare the effects of various parameters of a 1064 nm Nd:YAG laser in the treatment of enlarged facial pores. This was a prospective intra-individual left-right comparative study. A total of 40 individuals with enlarged facial pores were recruited for this study. Ten individuals were respectively treated on one half of the face with a quasi long-pulsed 1064 nm Nd:YAG laser (method 1), a Q-switched 1064 nm Nd:YAG laser (method 2), both quasi long-pulsed and Q-switched 1064 nm Nd:YAG lasers without carbon-suspended lotion (method 3), and both quasi long-pulsed and Q-switched 1064 nm Nd:YAG lasers with carbon-suspended lotion (method 4). The other half of the face was left untreated as a control. Five laser sessions were performed with a 3-week interval. The pore sizes were measured using an image analysis program and the sebum level was measured with a Sebumeter before and after the treatments. The pore size and sebum level decreased in all four methods on the treated side compared to the control (p pore size and sebum level.

    Intense focused ultrasound (IFUS) has been used successfully for skin tightening. To investigate the efficacy of IFUS in treating enlarged pores and to evaluate changes in skin elasticity and sebum production following IFUS. Twenty-two subjects with enlarged pores were randomized to receive a single treatment with IFUS using 1.5-mm transducer on one side of the face, and 3.0-mm transducer on the other. OBJECTIVE clinical assessments were made by blinded photographic evaluation. Subjective satisfaction and adverse effects were evaluated. Measurements of elasticity and sebum were performed at baseline, 3 and 6 weeks post-treatment. Physicians' evaluation showed clinical pore improvements in 86% and 91% of the IFUS-treated sites using 1.5-mm and 3.0-mm transducer, respectively. The mean improvement scores were 1.7 and 1.9 for 1.5-mm and 3.0-mm transducer, respectively, with no statistical differences. Cutometer measurement demonstrated a significant improvement in skin elasticity. Sebum level showed a reduction without statistical significance. There was a positive correlation between improvement in elasticity and pore improvement grades. All treatments were well tolerated without significant side effects. IFUS using 1.5-mm or 3.0-mm transducer was safe and effective for reducing enlarged pores in Asian skin with an improvement in skin elasticity.

    1984-01-01

    Radiographically, the size of the right ventricle of 54 heartworm-infected dogs was graded subjectively as normal, 1 +, 2 +, and 3 + and served to classify the dogs into groups A, B, C, and D. With M-mode echocardiograms, right ventricular enlargement ratios (RVE ratios) were determined for each dog by dividing the measured right ventricular internal diastolic dimension (RVIDd) by the expected RVIDd of a normal dog of the same body weight. The normal RVIDd relation to body weight was derived from 25 healthy heartworm-free control dogs. These two variables were linearly related with a correlation coefficient r 2 = 0.59. Means and standard deviations of the RVE ratio were calculated for each group. Despite wide ranges and considerable overlap, the ratio was significantly different (t-test, p < 0.005) between groups with the exception of groups A and B, and C and D. The incidence of electrocardiographic signs of right ventricular hypertrophy was also determined for each group; it was 38% in group C and 62% in group D. From this data, it was concluded that M-mode echocardiography is a very sensitive technique for the documentation of right ventricular dilatation in heartworm-infected dogs, correlating with radiographic impressions of right ventricular enlargement.

    Large vestibular aqueduct syndrome (LVAS) is a congenital disorder characterized by progressive or fluctuating sensorineural hearing loss of unknown etiology. Serial MR examinations were performed before and after the development of hearing loss in two patients with LVAS. The signal and volume of the enlarged endolymphatic sac (EES) vary even in ears with stable hearing. In ears with fluctuating hearing, changes in EES signals were observed in only one of two patients. The finding that the EES volume and signal intensity vary dynamically independently of hearing is important for future research into the pathophysiology of hearing loss in this syndrome. (orig.)

  8. Multiple Sources of Pressure for Change: The Barroso Commission and Energy Policy for an Enlarged EU

    Directory of Open Access Journals (Sweden)

    Jan Frederik Braun

    2009-11-01

    Full Text Available This article presents a preliminary analysis of how and why the role, work and status of the European Commission are changing in an enlarged European Union. It does so by focusing on multiple sources of pressure for change. These include: enlargement, new modes of governance, administrative reforms and changed leadership under Barroso. Combined, though not interlinked, these multiple sources of pressure are evidence of the increasing difficulty for the Commission to design and propose Community-wide answers to complex challenges in a more diverse Union. For this reason, the Commission under Barroso relies less on its traditional monopoly power to propose formal legislation and more on non-traditional modes of policy-making. Energy policy, especially its external dimension, constitutes a policy field that has been affected by enlargement, i.e. characterised by an increasing heterogeneity of needs and preferences among the member states. Not only does it resists Community-wide answers, it also allows the Commission, as an agent, to make use of bureaucratic drifts, i.e. exploit its strategic position in the EU’s governance system and use of a range of formal and informal resources of expertise. To deliver sustainable European added value to this complex policy area, however, the Commission must focus more on pragmatic policy results by making smart use of the EU’s increasing asymmetry, diversity and subsidiarity in a bottom-up approach. A non-legislative approach can serve as a modus vivendi to keep the momentum going in the Union’s difficult struggle to establish a workable energy regime.

    Timely detection of enlarged intrathoracic lymph nodes is of great importance in pediatric practice. Meanwhile there exist various mediastinal and lung root as well as anomalies and variants of their development, which could imitate the mediastinal lymph node hyperplasia. Their diagnosis is individually designed employing a complex of X-ray methods. In recent years the anatomo-physiological development of thoracic organs in children and teenagers has been affected by the acceleration process. Under the latters' impact the phenomenon of an increase in the large pulmonary vessels appeared in children with signs of high physical development, which caused lung root dilatation and produced an impression of the intrathoracic lymph node enlargement. The Valsalva functional tests should be used in combination with X-ray research methods

  13. Opposition to enlargement as a symbolic defence of group position: multilevel analyses of attitudes toward candidates' entries in the EU-25.

    Dixon, Jeffrey C

    2010-03-01

    Despite the sociological and geopolitical significance of EU enlargement and opinion toward it, extant literature is lacking a theory of enlargement opinion and an examination of opinion in the wake of the 2004 enlargement. This paper fills these gaps by developing a symbolic defence of group position model to explain opposition to the entries of candidate states (as of 2005: Bulgaria, Romania, Croatia, and Turkey) and to examine how these explanations differ for post-Communist EU members. Results of hierarchical multinomial logistic models of Eurobarometer (European Commission 2005) data from the EU-25 support the notion that the symbolic nature of enlargement shapes the effects of interests, threat, and other factors on opinion depending on candidates' position in a culturally and historically-rooted hierarchy of 'European-ness'. Attitudes toward Turkey's entry are less shaped by material interests than attitudes toward other candidates' entries, which is explained by Turkey's position at the bottom - and post-Communist countries' position in the middle - of this hierarchy in the post-Cold War era. Attitudes toward Turkey's entry are rather a function of the perceived threat that it poses to the group position and identity of Europeans, which is defended by the politically knowledgeable. While the lower levels of threat in post-socialist EU member countries help to account for their lower levels of opposition to candidates' entries, people in these countries to a greater extent use European identity as a way of symbolically distancing themselves from Turkey. Implications are discussed.

    The purpose of the study was to investigate the etiological factors and the audiological data of different types of inner ear malformations, which the authors thought might be helpful in elucidating the inter-relation among malformations and shedding light on pathogenesis. Retrospective study from 1998 to 2002 at a tertiary care university hospital. One hundred sixty consecutive children with a total of 302 affected ears undergoing high-resolution computed tomography of the temporal bone for sensorineural hearing loss were enrolled. The image results were correlated with causes and origins, hearing loss patterns, hearing levels, and audiogram configurations. Inner ear malformation was present in 114 (38%) ears. The most common malformations were enlarged vestibular aqueduct, incomplete partition of cochlea (Mondini dysplasia), large vestibule, and semicircular canal dysplasia, presenting either as isolated finding or in combination. Eighty-four (74%) ears had abnormalities confined to these four malformations; only 30 (26%) ears showed other malformations. Patients with complex of enlarged vestibular aqueduct, Mondini dysplasia, large vestibule, and semicircular canal dysplasia (EMVS complex) demonstrated a significantly higher incidence of fluctuating hearing loss (93%) and a better hearing level compared with those with other malformations. Homogeneity in audiological features among these four malformations was also disclosed. The authors identified a distinct clinical entity, the EMVS complex, which is characterized by fluctuating hearing loss and a better hearing level. The authors proposed that malformations belonging to this complex result from a common pathogenetic mechanism.

  16. The Classical Version of Stokes' Theorem Revisited

    DEFF Research Database (Denmark)

    Markvorsen, Steen

    2005-01-01

    Using only fairly simple and elementary considerations - essentially from first year undergraduate mathematics - we prove that the classical Stokes' theorem for any given surface and vector field in $\\mathbb{R}^{3}$ follows from an application of Gauss' divergence theorem to a suitable modification...... of the vector field in a tubular shell around the given surface. The intuitive appeal of the divergence theorem is thus applied to bootstrap a corresponding intuition for Stokes' theorem. The two stated classical theorems are (like the fundamental theorem of calculus) nothing but shadows of the general version...... to above. Our proof that Stokes' theorem follows from Gauss' divergence theorem goes via a well known and often used exercise, which simply relates the concepts of divergence and curl on the local differential level. The rest of the paper uses only integration in $1$, $2$, and $3$ variables together...

    Full Text Available Studies in human and non-human primates have confirmed the compensatory enlargement or positive remodeling (Glagov phenomenon of coronary vessels in the presence of focal stenosis. To our knowledge, this is the first study to document arterial enlargement in a metabolic syndrome animal model with diffuse coronary artery disease (DCAD in the absence of severe focal stenosis. Two different groups of Ossabaw miniature pigs were fed a high fat atherogenic diet for 4 months (Group I and 12 months (Group II, respectively. Group I (6 pigs underwent contrast enhanced computed tomographic angiography (CCTA and intravascular ultrasound (IVUS at baseline and after 4 months of high fat diet, whereas Group II (7 pigs underwent only IVUS at 12 months of high fat diet. IVUS measurements of the left anterior descending (LAD, left circumflex (LCX and right coronary (RCA arteries in Group I showed an average increase in their lumen cross-sectional areas (CSA of 25.8%, 11.4%, and 43.4%, respectively, as compared to baseline. The lumen CSA values of LAD in Group II were found to be between the baseline and 4 month values in Group I. IVUS and CCTA measurements showed a similar trend and positive correlation. Fractional flow reserve (FFR was 0.91 ± 0.07 at baseline and 0.93 ± 0.05 at 4 months with only 2.2%, 1.6% and 1% stenosis in the LAD, LCX and RCA, respectively. The relation between percent stenosis and lumen CSA shows a classical Glagov phenomenon in this animal model of DCAD.

    Retinitis pigmentosa (RP) refers to a group of inherited retinal degenerations resulting form rod and cone photoreceptor cell death. The rod cell death due to deleterious genetic mutations has been shown to occur mainly through apoptosis, whereas the mechanisms and features of the secondary cone cell death have not been fully elucidated. Our previous study showed that the cone cell death in rd10 mice, an animal model of RP, involves necrotic features and is partly mediated by the receptor interacting protein kinase. However, the relevancy of necrotic cone cell death in human RP patients remains unknown. In the present study, we showed that dying cone cells in rd10 mice exhibited cellular enlargement, along with necrotic changes such as cellular swelling and mitochondrial rupture. In human eyes, live imaging of cone cells by adaptive optics scanning laser ophthalmoscopy revealed significantly increased percentages of enlarged cone cells in the RP patients compared with the control subjects. The vitreous of the RP patients contained significantly higher levels of high-mobility group box-1, which is released extracellularly associated with necrotic cell death. These findings suggest that necrotic enlargement of cone cells is involved in the process of cone degeneration, and that necrosis may be a novel target to prevent or delay the loss of cone-mediated central vision in RP.

    Objective: to analyse whether ultrasound contrast agent (UCA) improves the diagnostic accuracy to differentiate between benign and malignant superficial lymph node enlargement by using colour-coded duplex sonography (CCDS) and power Doppler (PD). Methods: 32 patients with suspected malignant superficial lymph node enlargement prospectively underwent standardised ultrasound examinations using B-mode sonography and native and contrast-enhanced CCDS and PD immediately before biopsy. Solbiati-Index (longitudinal-transverse diameter ratio) and intranodal flow patterns by using different vascularisation types were assessed. Histological and sonographical findings were correlated. Results: 27 malignant and 5 benign lymph nodes were found. Solbiati-Index was lower in malignant lymph nodes than in benign nodes (mean 1.5 vs. 2.4, P<0.045). More intranodal flow patterns could be detected after UCA (53 vs. 43) but the number of correctly identified malignant nodes decreased after UCA (26 vs. 24) and the number of correctly identified benign nodes remained constant compared with native CCDS and PD. In 31% of the colour-mode studies, PD was considered to visualise more clearly intranodal vascular flow patterns than CCDS. Conclusion: despite depicting more intranodal vascular patterns, the use of an ultrasound contrast agent seems not to improve the diagnostic value of CCDS and PD compared with native colour-mode studies in superficial lymph node enlargement

    Full Text Available In the The Split-Level Fellowship, Wesley Baker analysed the role of individual members in the Church. He gave a name to a tragic phenomenon with which Church leaders are familiar. Although true of society in general it is especially true of the church. Baker called the difference between the committed few and the uninvolved many, Factor Beta. This reality triggers the question: Why are the majority of Christians in the world not missionally involved through personal witness and which factors consequently influence personal witness and missional involvement? This article explains how the range of personal witness and missional involvement found in local churches are rooted in certain fundamental factors and conditions which are mutually influencing each other and ultimately contribute towards forming a certain paradigm. This paradigm acts as the basis from which certain behavioural patterns (witness will manifest. The factors influencing witness are either described as accelerators or decelerators and their relativity and mutual relationships are considered. Factors acting as decelerators can severely hamper or even annul witness, while accelerators on the other hand, can have an immensely positive effect to enlarge the transformational influence of witness. In conclusion a transformational model is developed through which paradigms can be influenced and eventually changed. This model fulfils a diagnostic and remedial function and will support local churches to enlarge the individual and corporate missional involvement of believers.

Methods: A total of 38 eyes from 38 glaucoma patients with the generalized enlargement disc type were included. The microcirculation of the optic nerve head was examined with laser speckle flow graphy, and the mean blur rate in all areas, in vessel area, and in tissue area were calculated using the laser speckle flow graphy analyzer software. Average peripapillary retinal nerve fiber layer thickness was measured using Stratus optical coherence tomography, and cupping parameters were accessed using the Heidelberg retina tomograph. The mean deviation in the Humphrey field analyzer (30-2 SITA standard was analyzed. The correlation between these parameters was evaluated using the Spearman rank correlation coefficient. Results: The correlation coefficient of mean blur rate in all optic disc area to the average peripapillary retinal nerve fiber layer thickness, vertical C/D, and mean deviation were r = 0.7546 (P < 0.0001, r = –0.6208 (P < 0.0001, and r = 0.6010 (P = 0.0001, respectively. The mean blur rate in tissue area of the optic disc showed r = 0.7305 (P < 0.0001, r = –0.6438 (P < 0.0001, and r = 0.6338 (P < 0.0001. Conclusion: We found that the mean blur rate in the optic disc was significantly correlated with the average peripapillary retinal nerve fiber layer thickness, vertical C/D, and mean deviation in patients with the generalized enlargement disc type of glaucoma. In particular, the mean blur rate in tissue area was more

    1997-12-01

    More than 30 patients presented for reconstruction of penile deformities secondary to penile enlargement surgery performed by other physicians. Lengthening was performed by releasing the suspensory ligament of the penis and advancing pubic skin with a V-Y advancement flap. Girth was increased by injecting autologous fat. Specific complaints relating to the lengthening procedure involve hypertrophic and/or wide scars, a proximal penile hump from a thick, hair-bearing V-Y flap, and a low hanging penis. Complications relating to autologous fat injections include disappearance of fat, penile lumps and nodules, and shaft deformities. The repair of these deformities is described. From 1994 through October 1996, 19 men underwent 24 various combinations of reconstructive operations, such as scar revisions, V-Y advancement flap reversal, and removal of fat nodules and asymmetrical fat deposits. Penile appearance and function were improved. Complications include 1 hematoma requiring drainage, minor wound complications and 1 inadequately reversed V-Y flap. The methods of various repairs are discussed, including reconstructive limitations, timing and staging. Significant improvement can be achieved with proper reconstruction of penile deformities.

    In this study the radionuclide databases for two versions of the Clean Air Act Assessment Package-1988 (CAP88) computer model were assessed in detail. CAP88 estimates radiation dose and the risk of health effects to human populations from radionuclide emissions to air. This program is used by several U.S. Department of Energy (DOE) facilities to comply with National Emission Standards for Hazardous Air Pollutants regulations. CAP88 Mainframe, referred to as version 1.0 on the U.S. Environmental Protection Agency Web site (http://www.epa.gov/radiation/assessment/CAP88/), was the very first CAP88 version released in 1988. Some DOE facilities including the Savannah River Site still employ this version (1.0) while others use the more user-friendly personal computer Windows-based version 3.0 released in December 2007. Version 1.0 uses the program RADRISK based on International Commission on Radiological Protection Publication 30 as its radionuclide database. Version 3.0 uses half-life, dose, and risk factor values based on Federal Guidance Report 13. Differences in these values could cause different results for the same input exposure data (same scenario), depending on which version of CAP88 is used. Consequently, the differences between the two versions are being assessed in detail at Savannah River National Laboratory. The version 1.0 and 3.0 database files contain 496 and 838 radionuclides, respectively, and though one would expect the newer version to include all the 496 radionuclides, 35 radionuclides are listed in version 1.0 that are not included in version 3.0. The majority of these has either extremely short or long half-lives or is no longer in production; however, some of the short-lived radionuclides might produce progeny of great interest at DOE sites. In addition, 122 radionuclides were found to have different half-lives in the two versions, with 21 over 3 percent different and 12 over 10 percent different.

    Several techniques are available or under development for surface decontamination in nuclear facilities. Each technique has its merits; however, none of them is universally the best choice for all surface decontamination applications. Because of the multitude of factors which influence the environmental and economic aspects of selecting a surface decontamination technique, it is difficult to select the best method in a given situation; an objective basis for comparing techniques is needed. The objective of this project was to develop a software tool for use by personnel selecting a surface decontamination technique. The software incorporates performance data for available surface decontamination techniques. The beta release version of the Surface Decontamination Assistant Software has been completed and has undergone testing at the Energy and Environmental Research Center. Minor modifications to the software were completed, and a final release version of the software is ready to be issued

  12. Digital elevation models for site investigation programme in Oskarshamn. Site description version 1.2

    2005-06-01

    In the Oskarshamn area, a digital elevation model has been produced using elevation data from many elevation sources on both land and sea. Many elevation model users are only interested in elevation models over land, so the model has been designed in three versions: Version 1 describes land surface, lake water surface, and sea bottom. Version 2 describes land surface, sediment levels at lake bottoms, and sea bottoms. Version 3 describes land surface, sediment levels at lake bottoms, and sea surface. In cases where the different sources of data were not in point form 'such as existing elevation models of land or depth lines from nautical charts' they have been converted to point values using GIS software. Because data from some sources often overlaps with data from other sources, several tests were conducted to determine if both sources of data or only one source would be included in the dataset used for the interpolation procedure. The tests resulted in the decision to use only the source judged to be of highest quality for most areas with overlapping data sources. All data were combined into a database of approximately 3.3 million points unevenly spread over an area of about 800 km 2 . The large number of data points made it difficult to construct the model with a single interpolation procedure, the area was divided into 28 sub-models that were processed one by one and finally merged together into one single model. The software ArcGis 8.3 and its extension Geostatistical Analysis were used for the interpolation. The Ordinary Kriging method was used for interpolation. This method allows both a cross validation and a validation before the interpolation is conducted. Cross validation with different Kriging parameters were performed and the model with the most reasonable statistics was chosen. Finally, a validation with the most appropriate Kriging parameters was performed in order to verify that the model fit unmeasured localities. Since both the quality and the

    The effect of interpolation and super-resolution (SR) algorithms on quantitative and qualitative assessments of enlarged optical coherence tomography (OCT) images was investigated in this report. Spectral-domain OCT images from 30 eyes in 30 consecutive patients with diabetic macular edema (DME) and 20 healthy eyes in 20 consecutive volunteers were analyzed. Original image (OR) resolution was reduced by a factor of four. Images were then magnified by a factor of four with and without application of one of the following algorithms: bilinear (BL), bicubic (BC), Lanczos3 (LA), and SR. Differences in peak signal-to-noise ratio (PSNR), retinal nerve fiber layer (RNFL) thickness, photoreceptor layer status, and parallelism (reflects the complexity of photoreceptor layer alterations) were analyzed in each image type. The order of PSNRs from highest to lowest was SR > LA > BC > BL > non-processed enlarged images (NONE). The PSNR was statistically different in all groups. The NONE, BC, and LA images resulted in significantly thicker RNFL measurements than the OR image. In eyes with DME, the photoreceptor layer, which was hardly identifiable in NONE images, became detectable with algorithm application. However, OCT photoreceptor parameters were still assessed as more undetectable than in OR images. Parallelism was not statistically different in OR and NONE images, but other image groups had significantly higher parallelism than OR images. Our results indicated that interpolation and SR algorithms increased OCT image resolution. However, qualitative and quantitative assessments were influenced by algorithm use. Additionally, each algorithm affected the assessments differently. PMID:26024236

    Full Text Available Having no internal borders, what is a border for the European Union (EU? Which criteria does this powerful organization pursue in its decision-making on further expansion: geographical, political, cultural, economic or all of these? What is the profi t of the Union in advancing its external borders to the east? And why to the east and not the south or west across the Atlantic? Does it still mean that there is the reason for enlarging eastward based on the geographical belonging to Europe? This paper discusses the expansion of the European Union to the east with the main focus on its political and economic aspects of integration. The fi rst part includes introduction to the concept of Europe, historic background about the formation of the united Europe in terms of geography, culture, politics and economy, juxtaposing opinions and viewpoints of different experts and political scientists on “what is Europe?” and what are the core issues of its enlargement. The second and third parts are dedicated to the advantages and disadvantages of European Integration for both parties concerned – the EU and the candidate/member state, in the case of the former having its own “demarcation policy” towards certain regions of the continent when it comes to unifi cation. And the fourth part is about the communication and miscommunication of the informative bodies of the European Union that are responsible for public awareness on any process that goes on within the European family. The lack of information results in the ignorance of citizens of European and partner countries, which, of course, refl ects on the further processes of expansion on the political level and cultural perception and mentality on the social level. The conclusion sums up the research, and the bibliography lists the books, articles, monographs and Internet sources used in the course of the study.

    COOL (that is, a rule can pattern match on objects created using COOL). CLIPS 6.0 provides the capability to define functions, overloaded functions, and global variables interactively. In addition, CLIPS can be embedded within procedural code, called as a subroutine, and integrated with languages such as C, FORTRAN and Ada. CLIPS can be easily extended by a user through the use of several well-defined protocols. CLIPS provides several delivery options for programs including the ability to generate stand alone executables or to load programs from text or binary files. CLIPS 6.0 provides support for the modular development and execution of knowledge bases with the defmodule construct. CLIPS modules allow a set of constructs to be grouped together such that explicit control can be maintained over restricting the access of the constructs by other modules. This type of control is similar to global and local scoping used in languages such as C or Ada. By restricting access to deftemplate and defclass constructs, modules can function as blackboards, permitting only certain facts and instances to be seen by other modules. Modules are also used by rules to provide execution control. The CRSV (Cross-Reference, Style, and Verification) utility included with previous version of CLIPS is no longer supported. The capabilities provided by this tool are now available directly within CLIPS 6.0 to aid in the development, debugging, and verification of large rule bases. COSMIC offers four distribution versions of CLIPS 6.0: UNIX (MSC-22433), VMS (MSC-22434), MACINTOSH (MSC-22429), and IBM PC (MSC-22430).

    allows the user to generate C code to implement the network loaded into the system. This permits the placement of networks as components, or subroutines, in other systems. In short, once a network performs satisfactorily, the Generate C Code option provides the means for creating a program separate from NETS to run the network. Other features: files may be stored in binary or ASCII format; multiple input propagation is permitted; bias values may be included; capability to scale data without writing scaling code; quick interactive testing of network from the main menu; and several options that allow the user to manipulate learning efficiency. NETS is written in ANSI standard C language to be machine independent. The Macintosh version (MSC-22108) includes code for both a graphical user interface version and a command line interface version. The machine independent version (MSC-21588) only includes code for the command line interface version of NETS 3.0. The Macintosh version requires a Macintosh II series computer and has been successfully implemented under System 7. Four executables are included on these diskettes, two for floating point operations and two for integer arithmetic. It requires Think C 5.0 to compile. A minimum of 1Mb of RAM is required for execution. Sample input files and executables for both the command line version and the Macintosh user interface version are provided on the distribution medium. The Macintosh version is available on a set of three 3.5 inch 800K Macintosh format diskettes. The machine independent version has been successfully implemented on an IBM PC series compatible running MS-DOS, a DEC VAX running VMS, a SunIPC running SunOS, and a CRAY Y-MP running UNICOS. Two executables for the IBM PC version are included on the MS-DOS distribution media, one compiled for floating point operations and one for integer arithmetic.

    We have investigated the thyroid uptake of Tl-201 in 37 patients with various types of goiter, and in six with normal thyroids. Significant thallium uptake was found in all cases in which there was thyroid enlargement, including Graves' disease, toxic thyroid nodule, primary hypothyroidism, simple goiter, Hashimoto's disease, thyroid carcinoma, and thyroid adenoma. If goiter was absent, however, there was no demonstrable uptake - e.g., in secondary hypothyroidism, subacute thyroiditis, and the normal controls. Thallium uptake did not correlate with thyroid function tests such as BMR, T 3 -RU, T 3 , T 4 , TSH, antithyroid antibodies, or the 24-hr I-131 uptake. In 23 patients with diffuse goiter, on the other hand, maximum Tl-201 uptake correlated well with thyroid weight: r = 0.836 (p < 0.001); y = 0.02 x + 0.06

    Full Text Available Abstract The L p $L_{p}$ -geominimal surface area was introduced by Lutwak in 1996, which extended the important concept of the geominimal surface area. Recently, Wang and Qi defined the p-dual geominimal surface area, which belongs to the dual Brunn-Minkowski theory. In this paper, based on the concept of the dual Orlicz mixed volume, we extend the dual geominimal surface area to the Orlicz version and give its properties. In addition, the isoperimetric inequality, a Blaschke-Santaló type inequality, and the monotonicity inequality for the dual Orlicz geominimal surface areas are established.

  2. Proximal tubular hypertrophy and enlarged glomerular and proximal tubular urinary space in obese subjects with proteinuria.

    Full Text Available BACKGROUND: Obesity is associated with glomerular hyperfiltration, increased proximal tubular sodium reabsorption, glomerular enlargement and renal hypertrophy. A single experimental study reported an increased glomerular urinary space in obese dogs. Whether proximal tubular volume is increased in obese subjects and whether their glomerular and tubular urinary spaces are enlarged is unknown. OBJECTIVE: To determine whether proximal tubules and glomerular and tubular urinary space are enlarged in obese subjects with proteinuria and glomerular hyperfiltration. METHODS: Kidney biopsies from 11 non-diabetic obese with proteinuria and 14 non-diabetic lean patients with a creatinine clearance above 50 ml/min and with mild or no interstitial fibrosis were retrospectively analyzed using morphometric methods. The cross-sectional area of the proximal tubular epithelium and lumen, the volume of the glomerular tuft and of Bowman's space and the nuclei number per tubular profile were estimated. RESULTS: Creatinine clearance was higher in the obese than in the lean group (P=0.03. Proteinuria was similarly increased in both groups. Compared to the lean group, the obese group displayed a 104% higher glomerular tuft volume (P=0.001, a 94% higher Bowman's space volume (P=0.003, a 33% higher cross-sectional area of the proximal tubular epithelium (P=0.02 and a 54% higher cross-sectional area of the proximal tubular lumen (P=0.01. The nuclei number per proximal tubular profile was similar in both groups, suggesting that the increase in tubular volume is due to hypertrophy and not to hyperplasia. CONCLUSIONS: Obesity-related glomerular hyperfiltration is associated with proximal tubular epithelial hypertrophy and increased glomerular and tubular urinary space volume in subjects with proteinuria. The expanded glomerular and urinary space is probably a direct consequence of glomerular hyperfiltration. These effects may be involved in the pathogenesis of obesity

  3. Enlarge the training set based on inter-class relationship for face recognition from one image per person.

    Li, Qin; Wang, Hua Jing; You, Jane; Li, Zhao Ming; Li, Jin Xue

    2013-01-01

    In some large-scale face recognition task, such as driver license identification and law enforcement, the training set only contains one image per person. This situation is referred to as one sample problem. Because many face recognition techniques implicitly assume that several (at least two) images per person are available for training, they cannot deal with the one sample problem. This paper investigates principal component analysis (PCA), Fisher linear discriminant analysis (LDA), and locality preserving projections (LPP) and shows why they cannot perform well in one sample problem. After that, this paper presents four reasons that make one sample problem itself difficult: the small sample size problem; the lack of representative samples; the underestimated intra-class variation; and the overestimated inter-class variation. Based on the analysis, this paper proposes to enlarge the training set based on the inter-class relationship. This paper also extends LDA and LPP to extract features from the enlarged training set. The experimental results show the effectiveness of the proposed method.

  4. EU Enlargement: Migration flows from Central and Eastern Europe into the Nordic countries - exploiting a natural experiment

    Pytlikova, Mariola; Pedersen, Peder J.

    We look at migration flows from 8 Central and Eastern European Countries (CEECs) to 5 Nordic countries over the years 1985 - 2005 and we can exploit a natural experiment that arose from the fact that while Sweden opened its labour market from the day one of the 2004 EU enlargement, the other Nordic...... countries chose a transition period in relation to the "new" EU members. We employ a differences-in-differences estimator in our analysis. The results show that the estimated effect of the opening of Swedish labour market in 2004 on migration is insignificantly different from zero. Further, we...... are interested in the overall effect of the "EU entry" on migration. Therefore we look at migration flows from CEECs during the first round EU enlargement towards CEECs in 2004 and compare them with migration flows from Bulgaria and Romania. We again used a DD estimator in our analysis. The estimated effect...

    . The flexible structure of TRASYS allows considerable freedom in the definition and choice of solution method for a thermal radiation problem. The program's flexible structure has also allowed TRASYS to retain the same basic input structure as the authors update it in order to keep up with changing requirements. Among its other important features are the following: 1) up to 3200 node problem size capability with shadowing by intervening opaque or semi-transparent surfaces; 2) choice of diffuse, specular, or diffuse/specular radiant interchange solutions; 3) a restart capability that minimizes recomputing; 4) macroinstructions that automatically provide the executive logic for orbit generation that optimizes the use of previously completed computations; 5) a time variable geometry package that provides automatic pointing of the various parts of an articulated spacecraft and an automatic look-back feature that eliminates redundant form factor calculations; 6) capability to specify submodel names to identify sets of surfaces or components as an entity; and 7) subroutines to perform functions which save and recall the internodal and/or space form factors in subsequent steps for nodes with fixed geometry during a variable geometry run. There are two machine versions of TRASYS v27: a DEC VAX version and a Cray UNICOS version. Both versions require installation of the NASADIG library (MSC-21801 for DEC VAX or COS-10049 for CRAY), which is available from COSMIC either separately or bundled with TRASYS. The NASADIG (NASA Device Independent Graphics Library) plot package provides a pictorial representation of input geometry, orbital/orientation parameters, and heating rate output as a function of time. NASADIG supports Tektronix terminals. The CRAY version of TRASYS v27 is written in FORTRAN 77 for batch or interactive execution and has been implemented on CRAY X-MP and CRAY Y-MP series computers running UNICOS.

    characteristics of blunt trailing edge airfoils are caused by blunt body vortices at low angles of attack, and by the combined effect of separation and blunt body vortices at large angles of attack. With the increase of thickness of blunt trailing edge, the vibration amplitudes of lift and drag curves increase......The aerodynamic performance of blunt trailing edge airfoils generated from the DU- 91-W2-250, DU-97-W-300 and DU-96-W-350 airfoils by enlarging the thickness of trailing edge symmetrically from the location of maximum thickness to chord to the trailing edge were analyzed by using CFD and RFOIL...... methods at a chord Reynolds number of 3 × 106. The goal of this study is to analyze the aerodynamic performance of blunt trailing edge airfoils with different thicknesses of trailing edge and maximum thicknesses to chord.

    There currently exist a number of planetary boundary layer (PBL) schemes that can represent the effects of turbulence in daytime convective conditions, although these schemes remain a large source of uncertainty in meteorology and air quality model simulations. This study evaluates a recently developed combined local and nonlocal closure PBL scheme, the Asymmetric Convective Model, version 2 (ACM2), against PBL observations taken from radar wind profilers, a ground-based lidar, and multiple daytime radiosonde balloon launches. These observations were compared against predictions of PBLs from the Weather Research and Forecasting (WRF) model version 3.1 with the ACM2 PBL scheme option, and the Fifth-Generation Meteorological Model (MM5) version 3.7.3 with the Eta PBL scheme option that is currently being used to develop ozone control strategies in southeast Texas. MM5 and WRF predictions during the regulatory modeling episode were evaluated on their ability to predict the rise and fall of the PBL during daytime convective conditions across southeastern Texas. The MM5 predicted PBLs consistently underpredicted observations, and were also less than the WRF PBL predictions. The analysis reveals that the MM5 predicted a slower rising and shallower PBL not representative of the daytime urban boundary layer. Alternatively, the WRF model predicted a more accurate PBL evolution improving the root mean square error (RMSE), both temporally and spatially. The WRF model also more accurately predicted vertical profiles of temperature and moisture in the lowest 3 km of the atmosphere. Inspection of median surface temperature and moisture time-series plots revealed higher predicted surface temperatures in WRF and more surface moisture in MM5. These could not be attributed to surface heat fluxes, and thus the differences in performance of the WRF and MM5 models are likely due to the PBL schemes. An accurate depiction of the diurnal evolution of the planetary boundary layer (PBL) is

    Mutations in SLC26A4 cause Pendred syndrome (hearing loss with goiter) or DFNB4 (non-syndromic hearing loss with inner ear malformation, such as enlarged vestibular aqueduct or Mondini deformity). The relationship between mutations in SLC26A4 and Mondini deformity without enlarged vestibular aqueduct has not been studied in any Chinese deaf population. The purpose of this study was to assess whether mutations in the SLC26A4 gene cause Mondini deformity without an enlarged vestibular aqueduct (isolated Mondini deformity) in a Chinese population. In total, 144 patients with sensorineural hearing loss were included and subjected to high-resolution temporal bone CT. Among them, 28 patients with isolated Mondini dysplasia (MD group), 50 patients with enlarged vestibular aqueduct with Mondini dysplasia (EVA with MD group), 50 patients with enlarged vestibular aqueduct without Mondini dysplasia (EVA group), and 16 patients with other types of inner ear malformations (IEM group) were identified. The coding exons of SLC26A4 were analyzed in all subjects. DNA sequence analysis of SLC26A4 was performed in all 144 patients. In the different groups, the detection rate of the SLC26A4 mutation differed. In the isolated MD group, only one single allelic mutation in SLC26A4 was found in one patient (1/28, 3.6%). In the EVA with MD group, biallelic and monoallelic SLC26A4 mutations were identified in 46 patients (46/50, 92.0%) and three patients (3/50, 6.0%), respectively. Also, in the EVA group, biallelic and monoallelic SLC26A4 mutations were identified in 46 patients (46/50, 92.0%) and three patients (3/50, 6.0%), respectively. These percentages were identical to those in the EVA plus MD group. Only two patients carried monoallelic mutations of the SLC26A4 gene in the IEM group (2/16, 12.5%). There were significant differences in the frequency of SLC26A4 mutation among the groups (P0.5). Although mutations in the SLC26A4 gene were frequently found in Chinese EVA patients with and

    In this report, the results generated by RESRAD-RDD version 2.01 are compared with those produced by RESRAD-RDD version 1.7 for different scenarios with different sets of input parameters. RESRAD-RDD version 1.7 is spreadsheet-driven, performing calculations with Microsoft Excel spreadsheets. RESRAD-RDD version 2.01 revamped version 1.7 by using command-driven programs designed with Visual Basic.NET to direct calculations with data saved in Microsoft Access database, and re-facing the graphical user interface (GUI) to provide more flexibility and choices in guideline derivation. Because version 1.7 and version 2.01 perform the same calculations, the comparison of their results serves as verification of both versions. The verification covered calculation results for 11 radionuclides included in both versions: Am-241, Cf-252, Cm-244, Co-60, Cs-137, Ir-192, Po-210, Pu-238, Pu-239, Ra-226, and Sr-90. At first, all nuclidespecific data used in both versions were compared to ensure that they are identical. Then generic operational guidelines and measurement-based radiation doses or stay times associated with a specific operational guideline group were calculated with both versions using different sets of input parameters, and the results obtained with the same set of input parameters were compared. A total of 12 sets of input parameters were used for the verification, and the comparison was performed for each operational guideline group, from A to G, sequentially. The verification shows that RESRAD-RDD version 1.7 and RESRAD-RDD version 2.01 generate almost identical results; the slight differences could be attributed to differences in numerical precision with Microsoft Excel and Visual Basic.NET. RESRAD-RDD version 2.01 allows the selection of different units for use in reporting calculation results. The results of SI units were obtained and compared with the base results (in traditional units) used for comparison with version 1.7. The comparison shows that RESRAD

    40 CFR Part 61 (Subpart H of the NESHAP) requires DOE facilities to use approved sampling procedures, computer models, or other approved procedures when calculating Effective Dose Equivalent (EDE) values to members of the public. Currently version 1.0 of the approved computer model CAP88-PC is used to calculate EDE values. The DOE has upgraded the CAP88-PC software to version 2.0. This version provides simplified data entry, better printing characteristics, the use of a mouse, and other features. The DOE has developed and released version 2.0 for testing and comment. This new software is a WINDOWS based application that offers a new graphical user interface with new utilities for preparing and managing population and weather data, and several new decay chains. The program also allows the user to view results before printing. This document describes a test that confirmed CAP88-PC version 2.0 generates results comparable to the original version of the CAP88-PC program

    Non-Hodgkin's lymphoma (NHL) is the fourth most common childhood malignancy. Uterine involvement with NHL is well described in adults, rare in children and has not been described in the first 2 years of life. While renal involvement in NHL is well recognised, diffuse renal enlargement is an uncommon finding. We report a unique case of B-cell lymphoma of primitive phenotype in a 15-month-old girl with uterine and renal involvement at presentation. We describe the US and MRI features at presentation that helped in the prospective diagnosis of this condition. (orig.)

    More than 4.1 million measurements of surface water partial pressure of CO2 obtained over the global oceans during 1968-2007 are listed in the Lamont-Doherty Earth Observatory (LDEO) database, which includes open ocean and coastal water measurements. The data assembled include only those measured by equilibrator-CO2 analyzer systems and have been quality-controlled based on the stability of the system performance, the reliability of calibrations for CO2 analysis, and the internal consistency of data. To allow re-examination of the data in the future, a number of measured parameters relevant to pCO2 measurements are listed. The overall uncertainty for the pCO2 values listed is estimated to be ± 2.5 µatm on the average. For simplicity and for ease of reference, this version is referred to as 2007, meaning that data collected through 31 December 2007 has been included. It is our intention to update this database annually. There are 37 new cruise/ship files in this update. In addition, some editing has been performed on existing files so this should be considered a V2007 file. Also we have added a column reporting the partial pressure of CO2 in seawater in units of Pascals. The data presented in this database include the analyses of partial pressure of CO2 (pCO2), sea surface temperature (SST), sea surface salinity (SSS), pressure of the equilibration, and barometric pressure in the outside air from the ship’s observation system. The global pCO2 data set is available free of charge as a numeric data package (NDP) from the Carbon Dioxide Information Analysis Center (CDIAC). The NDP consists of the oceanographic data files and this printed documentation, which describes the procedures and methods used to obtain the data.

    We have investigated the thyroid uptake of Tl-201 in 37 patients with various types of goiter, and in six with normal thyroids. Significant thallium uptake was found in all cases in which there was thyroid enlargement, including Graves' disease, toxic thyroid nodule, primary hypothyroidism, simple goiter, Hashimoto's disease, thyroid carcinoma, and thyroid adenoma. If goiter was absent, however, there was no demonstrable uptake - e.g., in secondary hypothyroidism, subacute thyroiditis, and the normal controls. Thallium uptake did not correlate with thyroid function tests such as BMR, T/sub 3/-RU, T/sub 3/, T/sub 4/, TSH, antithyroid antibodies, or the 24-hr I-131 uptake. In 23 patients with diffuse goiter, on the other hand, maximum Tl-201 uptake correlated well with thyroid weight: r = 0.836 (p < 0.001); y = 0.02 x + 0.06.

    Breathing oscillations in the discharge of an enlarged cylindrical-anode-layer Hall plasma accelerator are investigated by three-dimensional particle-in-cell (PIC) simulation. Different from the traditional breathing mode in a circular Hall plasma accelerator, the bulk plasma oscillation here is trigged by the potential barrier generated by the concentrated ion beam and substantial enough to compete with the anode voltage. The electric field near the anode is suppressed by the potential barrier thereby decreasing the electron density by {approx}36%. The discharge is restored to the normal level after the concentrated beam explodes and then it completes one cycle of electro-driven breathing oscillation. The breathing mode identified by the PIC simulation has a frequency range of {approx}156 kHz-{approx}250 kHz and does not vary monotonically with the discharge voltage.

    2010-01-01

    Understanding how land surfaces respond to climate change requires knowledge of land-surface processes, which control the degree to which interannual variability and mean trends in climatic variables affect the surface energy budget. We use the latest version of the Community Land Model version 3.5 (CLM3.5), which is driven by the latest updated hybrid reanalysis-observation atmospheric forcing dataset constructed by Princeton University, to obtain global distributions of the surface energy budget from 1948 to 2000. We identify climate change hotspots and surface energy flux hotspots from 1948 to 2000. Surface energy flux hotspots, which reflect regions with strong changes in surface energy fluxes, reveal seasonal variations with strong signals in winter, spring, and autumn and weak ones in summer. Locations for surface energy flux hotspots are not, however, fully linked with those for climate change hotspots, suggesting that only in some regions are land surfaces more responsive to climate change in terms of interannual variability and mean trends.

  1. Teichmüller Theory of Bordered Surfaces

    Full Text Available We propose the graph description of Teichmüller theory of surfaces with marked points on boundary components (bordered surfaces. Introducing new parameters, we formulate this theory in terms of hyperbolic geometry. We can then describe both classical and quantum theories having the proper number of Thurston variables (foliation-shear coordinates, mapping-class group invariance (both classical and quantum, Poisson and quantum algebra of geodesic functions, and classical and quantum braid-group relations. These new algebras can be defined on the double of the corresponding graph related (in a novel way to a double of the Riemann surface (which is a Riemann surface with holes, not a smooth Riemann surface. We enlarge the mapping class group allowing transformations relating different Teichmüller spaces of bordered surfaces of the same genus, same number of boundary components, and same total number of marked points but with arbitrary distributions of marked points among the boundary components. We describe the classical and quantum algebras and braid group relations for particular sets of geodesic functions corresponding to $A_n$ and $D_n$ algebras and discuss briefly the relation to the Thurston theory.

    1992-06-01

    This Report compares the Space Station version of ASTROMAG with free-flyer versions of ASTROMAG which could fly on an Atlas lla rocket and a Delta rocket. Launch with either free-flyer imposes severe weight limits on the magnet and its cryogenic system. Both versions of ASTROMAG magnet which fly on free-flying satellites do not have to be charged more than once during the mission. This permits one to simplify the charging system and the cryogenic system. The helium ll pump loop which supplies helium to the gas cooled electrical leads can be eliminated in both of the free-flyer versions of the ASTROMAG magnet. This report describes the superconducting dipole moment correction coils which are necessary for the magnet to operate on a free-flying satellite

  3. Versioning of printed products

    Tuijn, Chris

    2005-01-01

    During the definition of a printed product in an MIS system, a lot of attention is paid to the production process. The MIS systems typically gather all process-related parameters at such a level of detail that they can determine what the exact cost will be to make a specific product. This information can then be used to make a quote for the customer. Considerably less attention is paid to the content of the products since this does not have an immediate impact on the production costs (assuming that the number of inks or plates is known in advance). The content management is typically carried out either by the prepress systems themselves or by dedicated workflow servers uniting all people that contribute to the manufacturing of a printed product. Special care must be taken when considering versioned products. With versioned products we here mean distinct products that have a number of pages or page layers in common. Typical examples are comic books that have to be printed in different languages. In this case, the color plates can be shared over the different versions and the black plate will be different. Other examples are nation-wide magazines or newspapers that have an area with regional pages or advertising leaflets in different languages or currencies. When considering versioned products, the content will become an important cost factor. First of all, the content management (and associated proofing and approval cycles) becomes much more complex and, therefore, the risk that mistakes will be made increases considerably. Secondly, the real production costs are very much content-dependent because the content will determine whether plates can be shared across different versions or not and how many press runs will be needed. In this paper, we will present a way to manage different versions of a printed product. First, we will introduce a data model for version management. Next, we will show how the content of the different versions can be supplied by the customer

  4. A methodology to enlarge narrow stability windows

    The stability window in a wellbore design is defined by the difference between fracture pressure and collapse pressure. Deep water environments typically present narrow stability windows, because rocks have low strength due to under-compaction process. Often also, horizontal wells are drilled to obtain a better development of reservoirs placed in thin layers of sandstone. In this scenario, several challenges are faced when drilling in deep water. The traditional approach for predicting instabilities is to determine collapses and fractures at borehole wall. However, the initiation of rupture does not indicate that the borehole fails to perform its function as a wellbore. Thus, a methodology in which the stability window may be enlarged is desirable. This paper presents one practical analytical methodology that consists in allowing wellbore pressures smaller than the conventional collapse pressure, i.e., based upon failure on the borehole wall. This means that a collapse region (shear failure) will be developed around the borehole wall. This collapse region is pre-defined and to estimate its size is used a failure criterion. The aforementioned methodology is implemented in a user-friendly software, which can perform analyses of stress, pore pressure, formation failure, mud weight and mud salinity design for drilling in shale formations. Simulations of a wellbore drilling in a narrow stability window environment are performed to demonstrate the improvements of using the methodology. (author)

    COOL (that is, a rule can pattern match on objects created using COOL). CLIPS 6.0 provides the capability to define functions, overloaded functions, and global variables interactively. In addition, CLIPS can be embedded within procedural code, called as a subroutine, and integrated with languages such as C, FORTRAN and Ada. CLIPS can be easily extended by a user through the use of several well-defined protocols. CLIPS provides several delivery options for programs including the ability to generate stand alone executables or to load programs from text or binary files. CLIPS 6.0 provides support for the modular development and execution of knowledge bases with the defmodule construct. CLIPS modules allow a set of constructs to be grouped together such that explicit control can be maintained over restricting the access of the constructs by other modules. This type of control is similar to global and local scoping used in languages such as C or Ada. By restricting access to deftemplate and defclass constructs, modules can function as blackboards, permitting only certain facts and instances to be seen by other modules. Modules are also used by rules to provide execution control. The CRSV (Cross-Reference, Style, and Verification) utility included with previous version of CLIPS is no longer supported. The capabilities provided by this tool are now available directly within CLIPS 6.0 to aid in the development, debugging, and verification of large rule bases. COSMIC offers four distribution versions of CLIPS 6.0: UNIX (MSC-22433), VMS (MSC-22434), MACINTOSH (MSC-22429), and IBM PC (MSC-22430). Executable files, source code, utilities, documentation, and examples are included on the program media. All distribution versions include identical source code for the command line version of CLIPS 6.0. This source code should compile on any platform with an ANSI C compiler. Each distribution version of CLIPS 6.0, except that for the Macintosh platform, includes an executable for the

    Congenital high airway obstruction syndrome (CHAOS) caused by laryngeal atresia was diagnosed by prenatal ultrasound in a male fetus at 26 weeks of gestation. Findings included massive ascites, subcutaneous edema, enlarged hyperechogenic lungs with diaphragmatic inversion, dilated trachea, polyhydramnios, and breech presentation. Those findings of CHAOS spontaneously returned to normal by 33 weeks of gestation. However, the placenta was localized to the anterior uterine wall. In addition, the fetal position had been breech until delivery. At 36 weeks of gestation, a planned ex utero intrapartum treatment (EXIT) procedure was performed following intraoperative external cephalic version (ECV) in which the fetus was approached from the posterior wall of the uterus. Laryngoscopy revealed the predicted laryngeal obstruction, and tracheostomy was placed. Intraoperative ECV may be a useful technique in breech presentation before EXIT procedure. © 2012 The Authors.

    One of the most perspective methods to produce SoG-Si is refinement via metallurgical route. The most critical part of this route is refinement from boron and phosphorus, therefore, approach under development will address this problem. An approach of creating surface waves on silicon melt’s surface is proposed in order to enlarge its area and accelerate removal of boron via chemical reactions and evaporation of phosphorus. A two dimensional numerical model is created which include coupling of electromagnetic and fluid dynamic simulations with free surface dynamics. First results show behaviour similar to experimental results from literature.

    allows the user to generate C code to implement the network loaded into the system. This permits the placement of networks as components, or subroutines, in other systems. In short, once a network performs satisfactorily, the Generate C Code option provides the means for creating a program separate from NETS to run the network. Other features: files may be stored in binary or ASCII format; multiple input propagation is permitted; bias values may be included; capability to scale data without writing scaling code; quick interactive testing of network from the main menu; and several options that allow the user to manipulate learning efficiency. NETS is written in ANSI standard C language to be machine independent. The Macintosh version (MSC-22108) includes code for both a graphical user interface version and a command line interface version. The machine independent version (MSC-21588) only includes code for the command line interface version of NETS 3.0. The Macintosh version requires a Macintosh II series computer and has been successfully implemented under System 7. Four executables are included on these diskettes, two for floating point operations and two for integer arithmetic. It requires Think C 5.0 to compile. A minimum of 1Mb of RAM is required for execution. Sample input files and executables for both the command line version and the Macintosh user interface version are provided on the distribution medium. The Macintosh version is available on a set of three 3.5 inch 800K Macintosh format diskettes. The machine independent version has been successfully implemented on an IBM PC series compatible running MS-DOS, a DEC VAX running VMS, a SunIPC running SunOS, and a CRAY Y-MP running UNICOS. Two executables for the IBM PC version are included on the MS-DOS distribution media, one compiled for floating point operations and one for integer arithmetic.

    2005-06-01

    In the Oskarshamn area, a digital elevation model has been produced using elevation data from many elevation sources on both land and sea. Many elevation model users are only interested in elevation models over land, so the model has been designed in three versions: Version 1 describes land surface, lake water surface, and sea bottom. Version 2 describes land surface, sediment levels at lake bottoms, and sea bottoms. Version 3 describes land surface, sediment levels at lake bottoms, and sea surface. In cases where the different sources of data were not in point form 'such as existing elevation models of land or depth lines from nautical charts' they have been converted to point values using GIS software. Because data from some sources often overlaps with data from other sources, several tests were conducted to determine if both sources of data or only one source would be included in the dataset used for the interpolation procedure. The tests resulted in the decision to use only the source judged to be of highest quality for most areas with overlapping data sources. All data were combined into a database of approximately 3.3 million points unevenly spread over an area of about 800 km{sup 2}. The large number of data points made it difficult to construct the model with a single interpolation procedure, the area was divided into 28 sub-models that were processed one by one and finally merged together into one single model. The software ArcGis 8.3 and its extension Geostatistical Analysis were used for the interpolation. The Ordinary Kriging method was used for interpolation. This method allows both a cross validation and a validation before the interpolation is conducted. Cross validation with different Kriging parameters were performed and the model with the most reasonable statistics was chosen. Finally, a validation with the most appropriate Kriging parameters was performed in order to verify that the model fit unmeasured localities. Since both the

    Pelizaeus-Merzbacher disease (PMD) is a rare, X-linked disorder characterized by hypomyelination of the Central Nervous System due to mutations in the PLP1 gene. Certain mutations of the PLP1 gene correlate with specific clinical phenotypes and neuroimaging findings. We herein report a novel mutation of the PLP1 gene in two siblings with PMD associated with a rare and protean neuroimaging finding of optic nerve enlargement. To the best of our knowledge this is the first time that this novel mutation H133P of PLP1 gene is identified and clinically associated with optic nerve enlargement in PMD patients.

  13. Model-based version management system framework

    International Nuclear Information System (INIS)

    Mehmood, W.

    2016-01-01

    In this paper we present a model-based version management system. Version Management System (VMS) a branch of software configuration management (SCM) aims to provide a controlling mechanism for evolution of software artifacts created during software development process. Controlling the evolution requires many activities to perform, such as, construction and creation of versions, identification of differences between versions, conflict detection and merging. Traditional VMS systems are file-based and consider software systems as a set of text files. File based VMS systems are not adequate for performing software configuration management activities such as, version control on software artifacts produced in earlier phases of the software life cycle. New challenges of model differencing, merge, and evolution control arise while using models as central artifact. The goal of this work is to present a generic framework model-based VMS which can be used to overcome the problem of tradition file-based VMS systems and provide model versioning services. (author)

    2016-01-01

    To increase the surface area while decreasing the ligament size of an Nb anode pellet for use as a capacitor, we added Ce to an Mg melt; the dealloying reaction occurred at temperatures lower than 1023 K, the previously lowest recorded temperature for such a reaction. By analyzing the dealloying kinetics, we found the optimum dealloying conditions to produce a minimum ligament size of 100 nm in the Mg_9_5_._7Ce_4_._3 melt: 923 K for 420 s. Using these conditions, we increased the specific surface area of the Nb anode pellet to 4.3 m"2/g, which increased its mass-specific capacitance to 875,000 μFV/g.

    The aim of this study was to improve performance of the microbial electrolysis desalination and chemical-production cell (MEDCC) using enlarged anode and high applied voltages. MEDCCs with anode lengths of 9 and 48cm (i.e., the 9cm-anode MEDCC and 48cm-anode MEDCC, respectively) were tested under different voltages (1.2-3.0V). Our results demonstrated for the first time that the MEDCC could maintain high performance even under the applied voltage higher than that for water dissociation (i.e., 1.8V). Under the applied voltage of 2.5V, the maximum current density in the 48cm-anode MEDCC reached 32.8±2.6A/m 2 , which is one of the highest current densities reported so far in the bioelectrochemical system (BES). The relative abundance of Geobacter was changed along the anode length. Our results show the great potential of the BES with enlarged anode and high applied voltages. Copyright © 2017 Elsevier Ltd.

    2015-01-01

    Idiopathic gingival enlargement (GE) is a rare entity characterized by massive enlargement of the gingiva. It may be associated with other diseases/conditions characterizing a syndrome, but rarely documented in literature occurring along with chronic periodontitis. This case report describes a rare case of long standing massive GE in a systemically healthy, nonsyndromic young female involving both the arches, thereby posing a diagnostic dilemma. Furthermore, in this case, we compared two surgical approaches, that is, scalpel and electrosurgery for the convenience as well as the postoperative comfort of the patient. Quadrants 1 and 3 were treated by ledge and wedge technique using scalpel and blade while quadrants 2 and 4 were treated by electrosurgery. The patient was followed postoperatively up to 1-year. The massive GE subsided without recurrence and patient was completely satisfied with the treatment, though better compliance was observed at the site treated by conventional scalpel and blade technique.

  18. Enlarge the training set based on inter-class relationship for face recognition from one image per person.

    Directory of Open Access Journals (Sweden)

    Qin Li

    Full Text Available In some large-scale face recognition task, such as driver license identification and law enforcement, the training set only contains one image per person. This situation is referred to as one sample problem. Because many face recognition techniques implicitly assume that several (at least two images per person are available for training, they cannot deal with the one sample problem. This paper investigates principal component analysis (PCA, Fisher linear discriminant analysis (LDA, and locality preserving projections (LPP and shows why they cannot perform well in one sample problem. After that, this paper presents four reasons that make one sample problem itself difficult: the small sample size problem; the lack of representative samples; the underestimated intra-class variation; and the overestimated inter-class variation. Based on the analysis, this paper proposes to enlarge the training set based on the inter-class relationship. This paper also extends LDA and LPP to extract features from the enlarged training set. The experimental results show the effectiveness of the proposed method.

The program's flexible structure has also allowed TRASYS to retain the same basic input structure as the authors update it in order to keep up with changing requirements. Among its other important features are the following: 1) up to 3200 node problem size capability with shadowing by intervening opaque or semi-transparent surfaces; 2) choice of diffuse, specular, or diffuse/specular radiant interchange solutions; 3) a restart capability that minimizes recomputing; 4) macroinstructions that automatically provide the executive logic for orbit generation that optimizes the use of previously completed computations; 5) a time variable geometry package that provides automatic pointing of the various parts of an articulated spacecraft and an automatic look-back feature that eliminates redundant form factor calculations; 6) capability to specify submodel names to identify sets of surfaces or components as an entity; and 7) subroutines to perform functions which save and recall the internodal and/or space form factors in subsequent steps for nodes with fixed geometry during a variable geometry run. There are two machine versions of TRASYS v27: a DEC VAX version and a Cray UNICOS version. Both versions require installation of the NASADIG library (MSC-21801 for DEC VAX or COS-10049 for CRAY), which is available from COSMIC either separately or bundled with TRASYS.

  2. GWSCREEN: A Semi-analytical Model for Assessment of the Groundwater Pathway from Surface or Buried Contamination, Theory and User's Manual, Version 2.5

    Energy Technology Data Exchange (ETDEWEB)

    Rood, Arthur South

    1998-08-01

    GWSCREEN was developed for assessment of the groundwater pathway from leaching of radioactive and non-radioactive substances from surface or buried sources. The code was designed for implementation in the Track I and Track II assessment of Comprehensive Environmental Response, Compensation, and Liability Act sites identified as low probability hazard at the Idaho National Engineering Laboratory. The code calculates 1) the limiting soil concentration such that, after leaching and transport to the aquifer regulatory contaminant levels in groundwater are not exceeded, 2) peak aquifer concentration and associated human health impacts, and 3) aquifer concentrations and associated human health impacts as a function of time and space. The code uses a mass conservation approach to model three processes: contaminant release from a source volume, vertical contaminant transport in the unsaturated zone, and 2D or 3D contaminant transport in the saturated zone. The source model considers the sorptive properties and solubility of the contaminant. In Version 2.5, transport in the unsaturated zone is described by a plug flow or dispersive solution model. Transport in the saturated zone is calculated with a semi-analytical solution to the advection dispersion equation in groundwater. Three source models are included; leaching from a surface or buried source, infiltration pond, or user-defined arbitrary release. Dispersion in the aquifer may be described by fixed dispersivity values or three, spatial-variable dispersivity functions. Version 2.5 also includes a Monte Carlo sampling routine for uncertainty/sensitivity analysis and a preprocessor to allow multiple input files and multiple contaminants to be run in a single simulation. GWSCREEN has been validated against other codes using similar algorithms and techniques. The code was originally designed for assessment and screening of the groundwater pathway when field data are limited. It was intended to simulate relatively simple

    The number-transcoding task on the Japanese version of the Rapid Dementia Screening Test (RDST-J) requires mutual conversion between Arabic and Chinese numerals (209 to , 4054 to , to 681, to 2027). In this task, question and answer styles of Chinese numerals are written horizontally. We investigated the impact of changing the task so that Chinese numerals are written vertically. Subjects were 211 patients with very mild to severe Alzheimer's disease and 42 normal controls. Mini-Mental State Examination scores ranged from 26 to 12, and Clinical Dementia Rating scores ranged from 0.5 to 3. Scores of all four subtasks of the transcoding task significantly improved in the revised version compared with the original version. The sensitivity and specificity of total scores ≥9 on the RDST-J original and revised versions for discriminating between controls and subjects with Clinical Dementia Rating scores of 0.5 were 63.8% and 76.6% on the original and 60.1% and 85.8% on revised version. The revised RDST-J total score had low sensitivity and high specificity compared with the original RDST-J for discriminating subjects with Clinical Dementia Rating scores of 0.5 from controls. © 2017 Japanese Psychogeriatric Society.

    MULTI is a general purpose, high speed, high energy physics interface to data acquisition and data investigation system that runs on PDP-11 and VAX architecture. This paper describes the latest version of MULTI, which runs under RSX-11M version 4.1 and supports a modular approach to the separate tasks that interface to it, allowing the same system to be used in single CPU test beam experiments as well as multiple interconnected CPU, large scale experiments. MULTI uses CAMAC (IEE-583) for control and monitoring of an experiment, and is written in FORTRAN-77 and assembler. The design of this version, which simplified the interface between tasks, and eliminated the need for a hard to maintain homegrown I/O system is also discussed

    Full Text Available The Cloud Aerosol LIdar with Orthogonal Polarization (CALIOP, on board the CALIPSO platform, has measured profiles of total attenuated backscatter coefficient (level 1 products since June 2006. CALIOP's level 2 products, such as the aerosol backscatter and extinction coefficient profiles, are retrieved using a complex succession of automated algorithms. The goal of this study is to help identify potential shortcomings in the CALIOP version 2 level 2 aerosol extinction product and to illustrate some of the motivation for the changes that have been introduced in the next version of CALIOP data (version 3, released in June 2010. To help illustrate the potential factors contributing to the uncertainty of the CALIOP aerosol extinction retrieval, we focus on a one-day, multi-instrument, multiplatform comparison study during the CALIPSO and Twilight Zone (CATZ validation campaign on 4 August 2007. On that day, we observe a consistency in the Aerosol Optical Depth (AOD values recorded by four different instruments (i.e. space-borne MODerate Imaging Spectroradiometer, MODIS: 0.67 and POLarization and Directionality of Earth's Reflectances, POLDER: 0.58, airborne High Spectral Resolution Lidar, HSRL: 0.52 and ground-based AErosol RObotic NETwork, AERONET: 0.48 to 0.73 while CALIOP AOD is a factor of two lower (0.32 at 532 nm. This case study illustrates the following potential sources of uncertainty in the CALIOP AOD: (i CALIOP's low signal-to-noise ratio (SNR leading to the misclassification and/or lack of aerosol layer identification, especially close to the Earth's surface; (ii the cloud contamination of CALIOP version 2 aerosol backscatter and extinction profiles; (iii potentially erroneous assumptions of the aerosol extinction-to-backscatter ratio (Sa used in CALIOP's extinction retrievals; and (iv calibration coefficient biases in the CALIOP daytime attenuated backscatter coefficient profiles.

  7. Response Surface Modeling Tool Suite, Version 1.x

    Energy Technology Data Exchange (ETDEWEB)

    2016-07-05

    The Response Surface Modeling (RSM) Tool Suite is a collection of three codes used to generate an empirical interpolation function for a collection of drag coefficient calculations computed with Test Particle Monte Carlo (TPMC) simulations. The first code, "Automated RSM", automates the generation of a drag coefficient RSM for a particular object to a single command. "Automated RSM" first creates a Latin Hypercube Sample (LHS) of 1,000 ensemble members to explore the global parameter space. For each ensemble member, a TPMC simulation is performed and the object drag coefficient is computed. In the next step of the "Automated RSM" code, a Gaussian process is used to fit the TPMC simulations. In the final step, Markov Chain Monte Carlo (MCMC) is used to evaluate the non-analytic probability distribution function from the Gaussian process. The second code, "RSM Area", creates a look-up table for the projected area of the object based on input limits on the minimum and maximum allowed pitch and yaw angles and pitch and yaw angle intervals. The projected area from the look-up table is used to compute the ballistic coefficient of the object based on its pitch and yaw angle. An accurate ballistic coefficient is crucial in accurately computing the drag on an object. The third code, "RSM Cd", uses the RSM generated by the "Automated RSM" code and the projected area look-up table generated by the "RSM Area" code to accurately compute the drag coefficient and ballistic coefficient of the object. The user can modify the object velocity, object surface temperature, the translational temperature of the gas, the species concentrations of the gas, and the pitch and yaw angles of the object. Together, these codes allow for the accurate derivation of an object's drag coefficient and ballistic coefficient under any conditions with only knowledge of the object's geometry and mass.

    Alternative pretreatment strategies of dentin and adhesionare constantly being developed and studied with the goal of improving the adhesion of resin restorative materials with this tissue. The objectives of the present study were to evaluate the ability of airborne-particle abrasion (APA) with aluminum oxide on dentin to remove the smear layer and the effects produced on the dentin microstructure. The phosphoric acid (PA) was used for a comparison. For that, 20 human third molars were randomly allocated into two experimental groups, according to the dentin pretreatment method used: G1 (N = 10) - PA, G2 (N = 10) -APA. For dentin surface analyses, an environmental scanning electron microscope (ESEM) was employed to observe dentin surfaces before and after the procedures. Before pretreatment, the specimens of both groups were smear covered. After pretreatment, the G1 images revealed dentin tubule orifices opened, enlarged and some erosive effects. (G2) exposed tubule orifices without enlargement, but crack-like alterations were observed on the surfaces. In this way, APA with aluminum oxide was able to remove the smear layer. The influences of the dentin roughness on adhesion and the consequences on dentin integrity and hardness need further investigations. A good conditioning of the dentin before cementation is necessary in order to obtain a satisfactory rehabilitation in adhesive dentistry. So, it is necessary to know all methods to do it.

    1998-01-01

    Two slow-moving landslides in Honolulu, Hawaii, were the subject of photogrammetric measurements, field mapping, and subsurface investigation to learn whether surface observations can yield useful information consistent with results of subsurface investigation. Mapping focused on structural damage and on surface features such as scarps, shears, and toes. The x-y-z positions of photo-identifiable points were obtained from aerial photographs taken at three different times. The measurements were intended to learn if the shape of the landslide failure surface can be determined from systematic surface observations and whether surface observations about deformation are consistent with photogrammetrically-obtained displacement gradients. Field and aerial photographic measurements were evaluated to identify the boundaries of the landslides, distinguish areas of incipient landslide enlargement, and identify zones of active and passive failure in the landslides. Data reported here apply mainly to the Alani-Paty landslide, a translational, earth-block landslide that damaged property in a 3.4-ha residential area. It began moving in the 1970s and displacement through 1991 totaled 4 m. Thickness, determined from borehole data, ranges from about 7 to 10 m; and the slope of the ground surface averages about 9??. Field evidence of deformation indicated areas of potential landslide enlargement outside the well-formed landslide boundaries. Displacement gradients obtained photogrammetrically and deformation mapping both identified similar zones of active failure (longitudinal stretching) and passive failure (longitudinal shortening) within the body of the landslide. Surface displacement on the landslide is approximately parallel to the broadly concave slip surface.

  10. The enlargement of the European Union. Effects on trade and emissions of greenhouse gases

    International Nuclear Information System (INIS)

    Zhu, Xueqin; Van Ierland, Ekko

    2006-01-01

    With the gradual accession of various Central and Eastern European Countries (CEECs) to the European Union (EU), international trade between the EU and the CEECs will change as a result of trade liberalisation and the mobility of production factors within the EU. The EU and most of the CEECs have already committed themselves to reduce by 2008-2012 their emissions of greenhouse gases (GHGs) by 8% compared to the 1990 level. This paper reports on an investigation of the potential consequences of the enlargement of the EU and of the emission reduction target set by the Kyoto Protocol on the sectoral production patterns and international trade. A comparative-static general equilibrium model was developed to examine the impacts under different scenarios. For illustrative purposes, two regions (the EU and the CEECs) and three categories of goods and services (agricultural goods, industrial goods, and services) were included. The model was calibrated by the 1998 data. The model was subsequently applied to study the effects of free trade, the mobility of factors and the environmental constraints on production and international trade in light of the enlargement of the EU. We show that in this specific context, free trade is beneficial to economic welfare and does not necessarily increase emissions of greenhouse gases. The mobility of factors also increases economic welfare, but in the case of fixed production technology it may harm the environment through more emissions of GHGs. (author)

    COOL (that is, a rule can pattern match on objects created using COOL). CLIPS 6.0 provides the capability to define functions, overloaded functions, and global variables interactively. In addition, CLIPS can be embedded within procedural code, called as a subroutine, and integrated with languages such as C, FORTRAN and Ada. CLIPS can be easily extended by a user through the use of several well-defined protocols. CLIPS provides several delivery options for programs including the ability to generate stand alone executables or to load programs from text or binary files. CLIPS 6.0 provides support for the modular development and execution of knowledge bases with the defmodule construct. CLIPS modules allow a set of constructs to be grouped together such that explicit control can be maintained over restricting the access of the constructs by other modules. This type of control is similar to global and local scoping used in languages such as C or Ada. By restricting access to deftemplate and defclass constructs, modules can function as blackboards, permitting only certain facts and instances to be seen by other modules. Modules are also used by rules to provide execution control. The CRSV (Cross-Reference, Style, and Verification) utility included with previous version of CLIPS is no longer supported. The capabilities provided by this tool are now available directly within CLIPS 6.0 to aid in the development, debugging, and verification of large rule bases. COSMIC offers four distribution versions of CLIPS 6.0: UNIX (MSC-22433), VMS (MSC-22434), MACINTOSH (MSC-22429), and IBM PC (MSC-22430). Executable files, source code, utilities, documentation, and examples are included on the program media. All distribution versions include identical source code for the command line version of CLIPS 6.0. This source code should compile on any platform with an ANSI C compiler. Each distribution version of CLIPS 6.0, except that for the Macintosh platform, includes an executable for the

    Full Text Available Objectives The aim of this study was to test the hypothesis, that the effectiveness of irrigation in removing smear layer in the apical third of root canal system is dependent on the depth of placement of the irrigation needle into the root canal and the enlargement size of the canal. Materials and Methods Eighty sound human lower incisors were divided into eight groups according to the enlargement size (#25, #30, #35 and #40 and the needle penetration depth (3 mm from working length, WL-3 mm and 9 mm from working length, WL-9 mm. Each canal was enlarged to working length with Profile.06 Rotary Ni-Ti files and irrigated with 5.25% NaOCl. Then, each canal received a final irrigation with 3 mL of 3% EDTA for 4 min, followed by 5 mL of 5.25% NaOCl at different level (WL-3 mm and WL-9 mm from working length. Each specimen was prepared for the scanning electron microscope (SEM. Photographs of the 3mm area from the apical constriction of each canal with a magnification of ×250, ×500, ×1,000, ×2,500 were taken for the final evaluation. Results Removal of smear layer in WL-3 mm group showed a significantly different effect when the canal was enlarged to larger than #30. There was a significant difference in removing apical smear layer between the needle penetration depth of WL-3 mm and WL-9 mm. Conclusions Removal of smear layer from the apical portion of root canals was effectively accomplished with apical instrumentation to #35/40 06 taper file and 3 mm needle penetration from the working length.

    Periodontal disease is a multifactorial disease having various risk factors, but a dynamic interaction between bacterial products and host response in association with genetic and environmental factors is considered as the primary cause for periodontal tissue destruction in periodontitis. This bacterial-host interaction which is ever-so-present in periodontitis directs us toward utilizing antimicrobial agents along with the routine mechanical debridement. This case report present a case of a female patient with recurrent periodontal infections with gingival enlargement treated with systemic Minocycline in conjunction with the conventional non-surgical approach.

    Full Text Available Abstract Background The clinical relevance of resilience has received considerable attention in recent years. The aim of this study is to demonstrate the reliability and validity of the Japanese version of the Resilience Scale (RS and short version of the RS (RS-14. Findings The original English version of RS was translated to Japanese and the Japanese version was confirmed by back-translation. Participants were 430 nursing and university psychology students. The RS, Center for Epidemiologic Studies Depression Scale (CES-D, Rosenberg Self-Esteem Scale (RSES, Social Support Questionnaire (SSQ, Perceived Stress Scale (PSS, and Sheehan Disability Scale (SDS were administered. Internal consistency, convergent validity and factor loadings were assessed at initial assessment. Test-retest reliability was assessed using data collected from 107 students at 3 months after baseline. Mean score on the RS was 111.19. Cronbach's alpha coefficients for the RS and RS-14 were 0.90 and 0.88, respectively. The test-retest correlation coefficients for the RS and RS-14 were 0.83 and 0.84, respectively. Both the RS and RS-14 were negatively correlated with the CES-D and SDS, and positively correlated with the RSES, SSQ and PSS (all p Conclusions This study demonstrates that the Japanese version of RS has psychometric properties with high degrees of internal consistency, high test-retest reliability, and relatively low concurrent validity. RS-14 was equivalent to the RS in internal consistency, test-retest reliability, and concurrent validity. Low scores on the RS, a positive correlation between the RS and perceived stress, and a relatively low correlation between the RS and depressive symptoms in this study suggest that validity of the Japanese version of the RS might be relatively low compared with the original English version.

    We report the modulation of Raman scattering spectrum of chromophore/graphene hybrids by tunning the molecular polarization with different terminal groups (methyl, methoxy, nitrile, and two nitros). Based on the density functional theory, the specific dipole moment values of the chromophore molecules are calculated. An obvious surface-enhanced Raman scattering (SERS) was observed and the scattering intensity of molecule increases with enlarged dipole moment. According to the analysis of G band Raman shifts of graphene, the enhancement of the Raman signal can be attributed to strong electronic coupling between graphene and chromophore, which is closely related with the modulation of graphene Fermi surface by changing the dipole moment of the molecule. Besides, the optimization of the ground state geometry and the binding energy of the hybrids were also calculated with the Density Functional Based Tight Bonding (DFTB) method, which confirms that the enhanced Raman scattering of molecules on graphene arises from the improved energy level matching between graphene Fermi surface and molecular band, further providing a new way to design novel SERS devices.

    We use sensitivity analysis to identify the parameters that are most responsible for shaping land surface model (LSM) simulations and to understand the complex interactions in three versions of the Noah LSM: the standard version (STD), a version enhanced with a simple groundwater module (GW), and version augmented by a dynamic phenology module (DV). We use warm season, high-frequency, near-surface states and turbulent fluxes collected over nine sites in the US Southern Great Plains. We quantify changes in the pattern of sensitive parameters, the amount and nature of the interaction between parameters, and the covariance structure of the distribution of behavioral parameter sets. Using Sobol s total and first-order sensitivity indexes, we show that very few parameters directly control the variance of the model output. Significant parameter interaction occurs so that not only the optimal parameter values differ between models, but the relationships between parameters change. GW decreases parameter interaction and appears to improve model realism, especially at wetter sites. DV increases parameter interaction and decreases identifiability, implying it is overparameterized and/or underconstrained. A case study at a wet site shows GW has two functional modes: one that mimics STD and a second in which GW improves model function by decoupling direct evaporation and baseflow. Unsupervised classification of the posterior distributions of behavioral parameter sets cannot group similar sites based solely on soil or vegetation type, helping to explain why transferability between sites and models is not straightforward. This evidence suggests a priori assignment of parameters should also consider climatic differences.

  20. Plasma-surface interaction in negative hydrogen ion sources

    A negative hydrogen ion source delivers more beam current when Cs is introduced to the discharge, but a continuous operation of the source reduces the beam current until more Cs is added to the source. This behavior can be explained by adsorption and ion induced desorption of Cs atoms on the plasma grid surface of the ion source. The interaction between the ion source plasma and the plasma grid surface of a negative hydrogen ion source is discussed in correlation to the Cs consumption of the ion source. The results show that operation with deuterium instead of hydrogen should require more Cs consumption and the presence of medium mass impurities as well as ions of the source wall materials in the arc discharge enlarges the Cs removal rate during an ion source discharge.

    Full Text Available We proposed fabricating an aluminum microneedle array with a nanochannel structure on the surface by combining micromachining, electrolyte polishing, and anodization methods. The microneedle array provides a three-dimensional (3D structure that possesses several hundred times more surface area than a traditional nanochannel template. Therefore, the microneedle array can potentially be used in many technology applications. This 3D microneedle array device can not only be used for painless injection or extraction, but also for storage, highly sensitive detection, drug delivery, and microelectrodes. From the calculation we made, the microneedle array not only increases surface area, but also enlarges the capacity of the device. Therefore, the microneedle array can further be used on many detecting, storing, or drug delivering applications.

    Pulmonary bullae are a common late complication in patients with emphysema. Non-communicating emphysematous bullae may expand during air travel when the ambient pressure is reduced, resulting in various forms of barotrauma including pneumothorax and air embolism. We report a 62-yr-old man with emphysema who developed hemoptysis during international commercial air travel. CT scan of the chest obtained after the travel showed air-fluid level in an enlarged bulla. He underwent resection of the bulla and had a full recovery. This is a unique presentation of stretch injury of a bulla as a form of pulmonary barotrauma occurring during commercial air travel. With the most recent ruling by the Federal Aviation Administration to allow patients with advanced chronic obstructive lung disease to travel by air with their own supplemental oxygen devices, physicians need to be aware of this type of pulmonary barotrauma and properly advise such patients who are planning to travel by air.

    Squamous cell carcinoma (SCC) is a rare histological type of breast cancer. The cytological diagnosis of non-keratinising, poorly differentiated SCC is often difficult, and distinguishing it from invasive ductal carcinoma or apocrine carcinoma (AC) is especially challenging. We aimed to define the diagnostic cytological features of poorly differentiated SCC of the breast. We studied the cytological findings of poorly differentiated SCC (n=10) and compared them to those of IDC (n=15) and AC (n=14). The following six cytological features were evaluated: streaming arrangement, nucleolar enlargement, dense nuclei, cannibalism, atypical keratinocytes and necrotic background. SCC exhibited significantly higher frequencies of streaming arrangement (70% vs 6.7%, P=.002), nucleolar enlargement (80% vs 27%, P=.02), and necrotic background (80% vs 36%, P=.002) than invasive ductal carcinoma. The detection of two or three of these features yielded a higher sensitivity (80%) and specificity (93%) for the diagnosis of SCC. Streaming arrangement (70% vs 0%, Pstreaming arrangement, a necrotic background, nucleolar enlargement and cannibalism are useful indicators for the diagnosis of SCC of the breast. As such, greater attention should be paid to these morphological features in daily clinical practice. © 2017 John Wiley & Sons Ltd.

    Impacts on the coupled variability of the Indo-Pacific by including the effects of surface currents on surface stress are explored in four extended integrations of an experimental version of the Bureau of Meteorology's coupled seasonal forecast model POAMA. The first pair of simulations differs only in their treatment of momentum coupling: one version includes the effects of surface currents on the surface stress computation and the other does not. The version that includes the effect of surface currents has less mean-state bias in the equatorial Pacific cold tongue but produces relatively weak coupled variability in the Tropics, especially that related to the Indian Ocean dipole (IOD) and El Nino/Southern Oscillation (ENSO). The version without the effects of surface currents has greater bias in the Pacific cold tongue but stronger IOD and ENSO variability. In order to diagnose the role of changes in local coupling from changes in remote forcing by ENSO for causing changes in IOD variability, a second set of simulations is conducted where effects of surface currents are included only in the Indian Ocean and only in the Pacific Ocean. IOD variability is found to be equally reduced by inclusion of the local effects of surface currents in the Indian Ocean and by the reduction of ENSO variability as a result of including effects of surface currents in the Pacific. Some implications of these results for predictability of the IOD and its dependence on ENSO, and for ocean subsurface data assimilation are discussed. (orig.)

  7. Optimized mixed oils remarkably reduce the amount of surfactants in microemulsions without affecting oral bioavailability of ibuprofen by simultaneously enlarging microemulsion areas and enhancing drug solubility.

    The toxicity and irritation associated with high amounts of surfactants restrict the extensive utilization of microemulsions. To address these shortcomings, employing mixed oils to enlarge microemulsion areas therefore reducing surfactant contents is a promising strategy. However, what kinds of mixed oils are more efficient in enlarging microemulsion areas still remains unclear. In this research, we found that the chain length and degree of unsaturation of oils play a key role in enlarging microemulsion areas. The combination of moderate chain saturated oil caprylic/capric triglyceride (GTCC) with long chain unsaturated oil glycerol trioleate significantly increased the microemulsion areas. Solubility of ibuprofen in the mixed oils was unexpectedly and remarkably increased (almost 300mg/mL) compared with that (around 100mg/mL) of the single oil (GTCC), which also resulted in greatly increased solubility of ibuprofen in mixed oils-containing microemulsions. By optimizing the mixed oil formulation, the absolute amount of surfactant in drug-loaded microemulsions was reduced but increased drug oral bioavailability in rats was maintained. It could be concluded that the combined use of moderate chain oils and long chain unsaturated oils could not only acquire enlarged microemulsion areas but also enhanced drug solubility, therefore doubly reducing surfactant amount, which is extremely beneficial for developing safe microemulsions.

  8. Analysis of the penumbra enlargement in lung versus the Quality Index of photon beams: A methodology to check the dose calculation algorithm

    It is well known that considerable underdosage can occur at the edges of a tumor inside the lung because of the degradation of penumbra due to lack of lateral electronic equilibrium. Although present even at smaller energies, this phenomenon is more pronounced for higher energies. Apart from Monte Carlo calculation, most of the existing Treatment Planning Systems (TPSs) cannot deal at all, or with acceptable accuracy, with this effect. A methodology has been developed for assessing the dose calculation algorithms in the lung region where lateral electronic disequilibrium exists, based on the Quality Index (QI) of the incident beam. A phantom, consisting of layers of polystyrene and lung material, has been irradiated using photon beams of 4, 6, 15, and 20 MV. The cross-plane profiles of each beam for 5x5, 10x10, and 25x10 fields have been measured at the middle of the phantom with the use of films. The penumbra (20%-80%) and fringe (50%-90%) enlargement was measured and the ratio of the widths for the lung to that of polystyrene was defined as the Correction Factor (CF). Monte Carlo calculations in the two phantoms have also been performed for energies of 6, 15, and 20 MV. Five commercial TPS's algorithms were tested for their ability to predict the penumbra and fringe enlargement. A linear relationship has been found between the QI of the beams and the CF of the penumbra and fringe enlargement for all the examined fields. Monte Carlo calculations agree very well (less than 1% difference) with the film measurements. The CF values range between 1.1 for 4 MV (QI 0.620) and 2.28 for 20 MV (QI 0.794). Three of the tested TPS's algorithms could not predict any enlargement at all for all energies and all fields and two of them could predict the penumbra enlargement to some extent. The proposed methodology can help any user or developer to check the accuracy of its algorithm for lung cases, based on a simple phantom geometry and the QI of the incident beam. This check is

    2006-01-01

    The final version (3.0) of the Montage software has been released. To recapitulate from previous NASA Tech Briefs articles about Montage: This software generates custom, science-grade mosaics of astronomical images on demand from input files that comply with the Flexible Image Transport System (FITS) standard and contain image data registered on projections that comply with the World Coordinate System (WCS) standards. This software can be executed on single-processor computers, multi-processor computers, and such networks of geographically dispersed computers as the National Science Foundation s TeraGrid or NASA s Information Power Grid. The primary advantage of running Montage in a grid environment is that computations can be done on a remote supercomputer for efficiency. Multiple computers at different sites can be used for different parts of a computation a significant advantage in cases of computations for large mosaics that demand more processor time than is available at any one site. Version 3.0 incorporates several improvements over prior versions. The most significant improvement is that this version is accessible to scientists located anywhere, through operational Web services that provide access to data from several large astronomical surveys and construct mosaics on either local workstations or remote computational grids as needed.

    To estimate the frequency and volume of fetomaternal hemorrhage during external cephalic version for term breech singleton fetuses and to identify risk factors involved with this complication. A prospective observational study was performed including all patients undergoing a trial of external cephalic version for a breech presentation of at least 36 weeks of gestation between 1987 and 2001 in our center. A search for fetal erythrocytes using the standard Kleihauer-Betke test was obtained before and after each external cephalic version. The frequency and volume of fetomaternal hemorrhage were calculated. Putative risk factors for fetomaternal hemorrhage were evaluated by chi(2) test and Mann-Whitney U test. A Kleihauer-Betke test result was available before and after 1,311 trials of external cephalic version. The Kleihauer-Betke test was positive in 67 (5.1%) before the procedure. Of the 1,244 women with a negative Kleihauer-Betke test before external cephalic version, 30 (2.4%) had a positive Kleihauer-Betke test after the procedure. Ten (0.8%) had an estimated fetomaternal hemorrhage greater than 1 mL, and one (0.08%) had an estimated fetomaternal hemorrhage greater than 30 mL. The risk of fetomaternal hemorrhage was not influenced by parity, gestational age, body mass index, number of attempts at version, placental location, or amniotic fluid index. The risk of detectable fetomaternal hemorrhage during external cephalic version was 2.4%, with fetomaternal hemorrhage more than 30 mL in less than 0.1% of cases. These data suggest that the performance of a Kleihauer-Betke test is unwarranted in uneventful external cephalic version and that in Rh-negative women, no further Rh immune globulin is necessary other than the routine 300-microgram dose at 28 weeks of gestation and postpartum.

    The AIRS Science Team Version-6 retrieval algorithm is currently producing level-3 Climate Data Records (CDRs) from AIRS that have been proven useful to scientists in understanding climate processes. CDRs are gridded level-3 products which include all cases passing AIRS Climate QC. SRT has made significant further improvements to AIRS Version-6. At the last Science Team Meeting, we described results using SRT AIRS Version-6.22. SRT Version-6.22 is now an official build at JPL called 6.2.4. Version-6.22 results are significantly improved compared to Version-6, especially with regard to water vapor and ozone profiles. We have adapted AIRS Version-6.22 to run with CrIS/ATMS, at the Sounder SIPS which processed CrIS/ATMS data for August 2014. JPL AIRS Version-6.22 uses the Version-6 AIRS tuning coefficients. AIRS Version-6.22 has at least two limitations which must be improved before finalization of Version-7: Version-6.22 total O3 has spurious high values in the presence of Saharan dust over the ocean; and Version-6.22 retrieved upper stratospheric temperatures are very poor in polar winter. SRT Version-6.28 addresses the first concern. John Blaisdell ran the analog of AIRS Version-6.28 in his own sandbox at JPL for the 14th and 15th of every month in 2014 and all of July and October for 2014. AIRS Version-6.28a is hot off the presses and addresses the second concern.

    Full Text Available Abstract Background Mutations in SLC26A4 cause Pendred syndrome (hearing loss with goiter or DFNB4 (non-syndromic hearing loss with inner ear malformation, such as enlarged vestibular aqueduct or Mondini deformity. The relationship between mutations in SLC26A4 and Mondini deformity without enlarged vestibular aqueduct has not been studied in any Chinese deaf population. The purpose of this study was to assess whether mutations in the SLC26A4 gene cause Mondini deformity without an enlarged vestibular aqueduct (isolated Mondini deformity in a Chinese population. Methods In total, 144 patients with sensorineural hearing loss were included and subjected to high-resolution temporal bone CT. Among them, 28 patients with isolated Mondini dysplasia (MD group, 50 patients with enlarged vestibular aqueduct with Mondini dysplasia (EVA with MD group, 50 patients with enlarged vestibular aqueduct without Mondini dysplasia (EVA group, and 16 patients with other types of inner ear malformations (IEM group were identified. The coding exons of SLC26A4 were analyzed in all subjects. Results DNA sequence analysis of SLC26A4 was performed in all 144 patients. In the different groups, the detection rate of the SLC26A4 mutation differed. In the isolated MD group, only one single allelic mutation in SLC26A4 was found in one patient (1/28, 3.6%. In the EVA with MD group, biallelic and monoallelic SLC26A4 mutations were identified in 46 patients (46/50, 92.0% and three patients (3/50, 6.0%, respectively. Also, in the EVA group, biallelic and monoallelic SLC26A4 mutations were identified in 46 patients (46/50, 92.0% and three patients (3/50, 6.0%, respectively. These percentages were identical to those in the EVA plus MD group. Only two patients carried monoallelic mutations of the SLC26A4 gene in the IEM group (2/16, 12.5%. There were significant differences in the frequency of SLC26A4 mutation among the groups (P SLC26A4 mutation in the isolated MD group was

    2008-02-01

    Full Text Available This paper assesses the mean differences between the two ILAS-II data versions (1.4 and 2 by comparing them with MIPAS measurements made between May and October 2003. For comparison with ILAS-II results, MIPAS data processed at the Institut für Meteorologie und Klimaforschung, Karlsruhe, Germany (IMK in cooperation with the Instituto de Astrofísica de Andalucía (IAA in Granada, Spain, were used. The coincidence criteria of ±300 km in space and ±12 h in time for H2O, N2O, and CH4 and the coincidence criteria of ±300 km in space and ±6 h in time for ClONO2, O3, and HNO3 were used. The ILAS-II data were separated into sunrise (= Northern Hemisphere and sunset (= Southern Hemisphere. For the sunrise data, a clear improvement from version 1.4 to version 2 was observed for H2O, CH4, ClONO2, and O3. In particular, the ILAS-II version 1.4 mixing ratios of H2O and CH4 were unrealistically small, and those of ClONO2 above altitudes of 30 km unrealistically large. For N2O and HNO3, there were no large differences between the two versions. Contrary to the Northern Hemisphere, where some exceptional profiles deviated significantly from known climatology, no such outlying profiles were found in the Southern Hemisphere for both versions. Generally, the ILAS-II version 2 data were in better agreement with the MIPAS data than the version 1.4, and are recommended for quantitative analysis in the stratosphere. For H2O data in the Southern Hemisphere, further data quality evaluation is necessary.

    Cross-cultural adaptation and cross-sectional psychometric testing in a convenience sample of patients with low back pain. To translate and culturally adapt the Oswestry Disability Index version 2.1 (ODI 2.1) into a Mandarin Chinese version and to assess its reliability and validity. The Chinese ODI 2.1 has not been developed and validated. The ODI 2.1 was translated and culturally adapted to the Chinese version. The validity of the translated Chinese version was assessed by examining the relationship between the ODI and other well-known measures. Test-retest reliability was examined in 52 of these patients, who completed a second questionnaire within 1 week. Internal consistency of the ODI 2.1 was excellent with Cronbach's alpha = 0.903. The intraclass correlation coefficient of test-retest reliability was 0.89. The minimal detectable change was 12.8. The convergent validity of the Chinese ODI is supported by its high correlation with other physical functional status measures (Roland Morris Disability Questionnaire and SF-36 physical functioning subscale, r = 0.76 and -0.75, respectively), and moderate correlation with other measures (Visual Analogue Scale, r = 0.68) and certain SF-36 subscales (role-physical, bodily pain, and social functioning, r range: -0.49 to -0.57). As expected, the ODI was least correlated with nonfunctional measures (SF-36 mental subscale and role-emotional subscale, r = -0.25 and -0.33, respectively). The results of this study indicate that the Chinese version of the ODI 2.1 is a reliable and valid instrument for the measurement of functional status in patients with low back pain.

    The surgical approach to the jugular foramen has been considered to be very difficult and troublesome, because of the location in which important structures, such as the internal jugular vein, internal carotid artery and lower cranial nerves, converge in the narrow deep space. A case of huge neurofibroma, which extended from the tentorium cerebelli through the dilated jugular foramen to the level of the vertebral body of C 3 was presented. A 12-year-old girl was admitted with complaints of visual disturbance and palsy of the V-XII cranial nerves of the left side. Plain skull film showed prominent widening of the cranial sutures and enlargement of the sella turcica. Horizontal CT scan with contrast showed symmetrical ventricular dilatation and a heterogeneously enhanced mass, which was situated mainly in the left CP angle. Coronal CT scan with contrast revealed a huge mass and enlarged jugular foramen, through which the tumor extended to the level of the vertebral body of C 3 . Occlusion of the sigmoid sinus and the internal jugular vein of the left side was noticed in the vertebral angiography. Two-stage approach, the first one for removal of the intracranial tumor and the second one for extracranial tumor, was performed for its huge tumor. Several authors have reported excellent surgical approaches for the tumors situated in the jugular foramen. By our approach, modifying Gardner's original one, a wide operative field was obtained to remove the tumor around the jugular foramen with success. Our approach for the jugular foramen was described with illustrations. (author)

    Conclusion: In contrast to healthy volunteers, there was no enlargement of the RIJV when dialysis patients were in the Trendelenburg position. The reason for this phenomenon may be multifactorial, with diastolic dysfunction being the most likely cause, and further investigation is required to clarify the cause. Our investigation suggests that the supine position for central venous catheterization in dialysis patients is superior to the Trendelenburg position.

    Full Text Available Background: Acute myeloblastic leukaemia is a malignant bone marrow neoplasm of myeloid precursors of white blood cells. Due to its high morbidity rate, early diagnosis and appropriate medical therapy is essential. Methods: The article highlights normal blood alterations like anaemia, thrombocytopenia, leukocytosis and advanced diagnostic aids like flow cytometry, special staining as a diagnostic modality as well as for prognostic information in acute leukaemia, particularly as a tool for assigning lineage and facilitating further pathologic classification which may be helpful in influencing treatment strategies.Results: On clinical examination the case presented with features of inflammatory gingival enlargement with presence of local deposits and calculus. Routine blood examination anaemia, thrombocytopenia, leukocytosis with haemoglobin 5.6 gm% and total leukocyte count of 1,12,000 / cu mm suggestive of leukaemia. Myeloperoxidase and leukocyte nonspecific esterase (NSE special stain were used which showed presence of myeloblasts in the peripheral smear suggestive of acute myelocytic leukaemia. Flow cytometry were done which further helped in interpretation of these cells which showed to be strongly positive for CD45, CD13, CD14, and anti HLADR and moderately positive for CD4, CD34 and Anti MPO confirming to be case of AML-M4 with 57.73% gating.Conclusions: Fact that gingival alterations are sometimes the first manifestations of the disease implies that dental professionals must be sufficiently familiarized with the clinical manifestations of systemic diseases. The timely referral by the general dentist for a suspicious lesion provided an early diagnosis and early intervention reducing the patient morbidity.

  2. Field-Theoretic Weyl Deformation Quantization of Enlarged Poisson Algebras

    Directory of Open Access Journals (Sweden)

    2008-05-01

    Full Text Available C*-algebraic Weyl quantization is extended by allowing also degenerate pre-symplectic forms for the Weyl relations with infinitely many degrees of freedom, and by starting out from enlarged classical Poisson algebras. A powerful tool is found in the construction of Poisson algebras and non-commutative twisted Banach-*-algebras on the stage of measures on the not locally compact test function space. Already within this frame strict deformation quantization is obtained, but in terms of Banach-*-algebras instead of C*-algebras. Fourier transformation and representation theory of the measure Banach-*-algebras are combined with the theory of continuous projective group representations to arrive at the genuine C*-algebraic strict deformation quantization in the sense of Rieffel and Landsman. Weyl quantization is recognized to depend in the first step functorially on the (in general infinite dimensional, pre-symplectic test function space; but in the second step one has to select a family of representations, indexed by the deformation parameter h. The latter ambiguity is in the present investigation connected with the choice of a folium of states, a structure, which does not necessarily require a Hilbert space representation.

    1995-12-01

    Evaluating the need for and the effectiveness of remedial cleanup at waste sites often includes finding average contaminant concentrations and identifying pockets of contamination called hot spots. The standard tool for calculating the probability of detecting pockets of contamination called hot spots has been the ELIPGRID code of singer and Wickman. The ELIPGRID-PC program has recently made this algorithm available for an IBM reg-sign personal computer (PC) or compatible. A new version of ELIPGRID-PC, incorporating Monte Carlo test results and simple graphics, is herein described. Various examples of how to use the program for both single and multiple hot spot cases are given. The code for an American National Standards Institute C version of the ELIPGRID algorithm is provided, and limitations and further work are noted. This version of ELIPGRID-PC reliably meets the goal of moving Singer's ELIPGRID algorithm to the PC

    The clinical relevance of resilience has received considerable attention in recent years. The aim of this study is to demonstrate the reliability and validity of the Japanese version of the Resilience Scale (RS) and short version of the RS (RS-14). The original English version of RS was translated to Japanese and the Japanese version was confirmed by back-translation. Participants were 430 nursing and university psychology students. The RS, Center for Epidemiologic Studies Depression Scale (CES-D), Rosenberg Self-Esteem Scale (RSES), Social Support Questionnaire (SSQ), Perceived Stress Scale (PSS), and Sheehan Disability Scale (SDS) were administered. Internal consistency, convergent validity and factor loadings were assessed at initial assessment. Test-retest reliability was assessed using data collected from 107 students at 3 months after baseline. Mean score on the RS was 111.19. Cronbach's alpha coefficients for the RS and RS-14 were 0.90 and 0.88, respectively. The test-retest correlation coefficients for the RS and RS-14 were 0.83 and 0.84, respectively. Both the RS and RS-14 were negatively correlated with the CES-D and SDS, and positively correlated with the RSES, SSQ and PSS (all p reliability, and relatively low concurrent validity. RS-14 was equivalent to the RS in internal consistency, test-retest reliability, and concurrent validity. Low scores on the RS, a positive correlation between the RS and perceived stress, and a relatively low correlation between the RS and depressive symptoms in this study suggest that validity of the Japanese version of the RS might be relatively low compared with the original English version.

    To compare the efficacy of chlorhexidine, Persica mouthwash and electric toothbrushes in improving gingival enlargement in patients with fixed orthodontic appliances. Seventy-two orthodontic patients with at least two sites of gingival enlargement were randomly allocated into four equal groups: 1) manual toothbrush; 2) electric toothbrush; 3) manual toothbrush+Persica mouthwash; 4) manual toothbrush+chlorhexidine mouthwash. All participants were instructed to brush their teeth at least twice a day. The subjects in groups 3 and 4 were instructed to use Persica or chlorhexidine according to the respective manufacturer's instructions. Bleeding on probing (BOP) index, gingival index (GI), O'Leary's plaque index (PI) and constructed hyperplastic index (HI) of all the subjects were measured in a blind manner at the start of the study and 2 weeks later. Changes of indices in the entire oral cavity and individual affected teeth were analysed with SPSS 16 using chi-square, ANOVA, ANCOVA, LSD and the paired t-test. In the entire oral cavity, there was a statistically significant improvement in indices in all the groups except for HI, which significantly improved only in group 4 (p=0.001). Data of individual teeth with hyperplastic gingiva showed significant reduction of all the variables except for HI in group 1 (p=0.08). No significant differences were found between groups 1 and 2 or between groups 3 and 4. The efficacy of Persica was similar to that of chlorhexidine in improving gingival conditions. None of the treatment modalities could reduce gingival enlargement to the clinically acceptable level of health.

    To assess the outcome of external cephalic version for routine management of malpresenting foetuses at term. Prospective observational study. Tertiary teaching hospital, Malaysia. From September 2003 to June 2004, a study involving 41 pregnant women with malpresentation at term was undertaken. An external cephalic version protocol was implemented. Data were collected for identifying characteristics associated with success or failure of external cephalic version. Maternal and foetal outcome measures including success rate of external cephalic version, maternal and foetal complications, and characteristics associated with success or failure; engagement of presenting part, placental location, direction of version, attempts at version, use of intravenous tocolytic agent, eventual mode of delivery, Apgar scores, birth weights, and maternal satisfaction with the procedure. Data were available for 38 women. External cephalic version was successful in 63% of patients; the majority (75%) of whom achieved a vaginal delivery. Multiparity (odds ratio=34.0; 95% confidence interval, 0.67-1730) and high amniotic fluid index (4.9; 1.3-18.2) were associated with successful external cephalic version. Engagement of presenting part (odds ratio=0.0001; 95% confidence interval, 0.00001-0.001) and a need to resort to backward somersault (0.02; 0.00001-0.916) were associated with poor success rates. Emergency caesarean section rate for foetal distress directly resulting from external cephalic version was 8%, but there was no perinatal or maternal adverse outcome. The majority (74%) of women were satisfied with external cephalic version. External cephalic version has acceptable success rates. Multiparity, liquor volume, engagement of presenting part, and the need for backward somersault were strong predictors of outcome. External cephalic version is relatively safe, simple to learn and perform, and associated with maternal satisfaction. Modern obstetric units should routinely offer the

    To systematically review the literature on external cephalic version-related complications and to assess if the outcome of a version attempt is related to complications. In March 2007 we searched MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials. Studies reporting on complications from an external cephalic version attempt for singleton breech pregnancies after 36 weeks of pregnancy were selected. We calculated odds ratios (ORs) from studies that reported both on complications as well as on the position of the fetus immediately after the procedure. We found 84 studies, reporting on 12,955 version attempts that reported on external cephalic version-related complications. The pooled complication rate was 6.1% (95% CI 4.7-7.8), 0.24% for serious complications (95% confidence interval [CI] 0.17-0.34) and 0.35% for emergency cesarean deliveries (95% CI 0.26-0.47). Complications were not related to external cephalic version outcome (OR 1.2 (95% CI 0.93-1.7). External cephalic version is a safe procedure. Complications are not related to the fetal position after external cephalic version.

    Full Text Available Background: Adenoid hypertrophy is one of the most common health problems affecting the paediatric population. This study aims to correlate adenoidal nasopharyngeal ratio (ANR with symptoms of enlarged adenoids in children with enlarged adenoids. Materials and Methods: It was a year, cross-sectional, hospital-based study conducted at Lautech Teaching Hospital, Osogbo. ANR was determined by dividing adenoidal depth with nasopharyngeal depth on the plain lateral radiographs. Results: A total of 90 consecutive children consisting of 61 males and 29 females were included in the study with M:F ratio of 2.1:1. Their ages ranged from 8 months to 11 years. All the patients presented with nasal obstruction, mouth breathing and noisy breathing. Majority (64.5% had severe obstructions with preponderance among children of 3-5 years (39.9%. Linear regression analysis showed significant association between age and ANR (t = 10.447, P < 0.001. There was high significant association (P < 0.05 between presenting symptoms and degree of nasopharyngeal airway obstruction; for snoring (r = 0.251, P = 0.000, sleep apnoea (r = 0.594, P = 0.000, nasal discharge (r = 0.314, P = 0.001, excessive daytime sleepiness (r = 0.219, P = 0.019 and failure to thrive (r = 0.240, P = 0.011. Conclusion: Lateral X-ray of the nasopharynx is an effective tool to evaluate children with suspected adenoid hypertrophy. It correlates well with patients′ symptoms and provides objective measures of adenoid hypertrophy.

    Based on closed-orbit theory, the photodetachment of H − in a gradient electric field near a metal surface is studied. It is demonstrated that the gradient electric field has a significant influence on the photodetachment of negative ions near a metal surface. With the increase of the gradient of the electric field, the oscillation in the photodetachment cross section becomes strengthened. Besides, in contrast to the photodetachment of H − near a metal surface in a uniform electric field, the oscillating amplitude and the oscillating region in the cross section of a gradient electric field also become enlarged. Therefore, we can use the gradient electric field to control the photodetachment of negative ions near a metal surface. We hope that our results will be useful for understanding the photodetachment of negative ions in the vicinity of surfaces, cavities, and ion traps. (atomic and molecular physics)

    We proposed fabricating an aluminum micro needle array with a nano channel structure on the surface by combining micromachining, electrolyte polishing, and anodization methods. The micro needle array provides a three-dimensional (3D) structure that possesses several hundred times more surface area than a traditional nano channel template. Therefore, the micro needle array can potentially be used in many technology applications. This 3D micro needle array device can not only be used for painless injection or extraction, but also for storage, highly sensitive detection, drug delivery, and microelectrodes. From the calculation we made, the micro needle array not only increases surface area, but also enlarges the capacity of the device. Therefore, the micro needle array can further be used on many detecting, storing, or drug delivering applications.

    Double-contrast upper gastrointestinal barium X-ray radiography (UGI-XR) is the standard gastric cancer screening method in Japan. Atrophic gastritis and enlarged gastric folds are considered the two major features of Helicobacter pylori-induced chronic gastritis, but the clinical meaning of evaluating them by UGI-XR has not been elucidated. We analyzed healthy UGI-XR examinees without a history of gastrectomy, previous Helicobacter pylori eradication and usage of gastric acid suppressants. Of the 6433 subjects, 1936 (30.1 %) had atrophic gastritis and 1253 (19.5 %) had enlarged gastric folds. During the 3-year prospective observational follow-up, gastric cancer developed in seven subjects, six of whom (85.7 %) had atrophic gastritis with H. pylori infection and five of whom (71.4 %) had enlarged gastric folds with H. pylori infection. The Kaplan-Meier method with log-rank testing revealed that both UGI-XR-based atrophic gastritis (p = 0.0011) and enlarged gastric folds (p = 0.0003) are significant predictors for future gastric cancer incidence.

    2018-03-01

    In the paper Commun Anal Geom 16(1):217-229, 2008, a rigidity result was obtained for outermost marginally outer trapped surfaces (MOTSs) that do not admit metrics of positive scalar curvature. This allowed one to treat the "borderline case" in the author's work with R. Schoen concerning the topology of higher dimensional black holes (Commun Math Phys 266(2):571-576, 2006). The proof of this rigidity result involved bending the initial data manifold in the vicinity of the MOTS within the ambient spacetime. In this note we show how to circumvent this step, and thereby obtain a pure initial data version of this rigidity result and its consequence concerning the topology of black holes.

    2016-01-01

    The Karolinska Sleepiness Scale (KSS) is frequently used to study sleepiness in various contexts. However, it exists in two versions, one with labels on every other step (version A), and one with labels on every step (version B) on the 9-point scale. To date, there are no studies examining whether these versions can be used interchangeably. The two versions were here compared in a 24 hr wakefulness study of 12 adults. KSS ratings were obtained every hour, alternating version A and B. Results indicated that the two versions are highly correlated, do not have different response distributions on labeled and unlabeled steps, and that the distributions across all steps have a high level of correspondence (Kappa = 0.73). It was concluded that the two versions are quite similar.

    2012-11-01

    Full Text Available Abstract Introduction Unfamiliarity with certain clinical presentations, as illustrated in these cases, can lead to delayed diagnoses that in turn cause increased morbidity, prolonged hospitalization, and the need for autopsy. Case presentation In Case 1, a 63-year-old Caucasian woman presented with hepatic enlargement and insufficiency which progressed and resulted in her death over a period of less than 2 weeks. The patient underwent a detailed workup included magnetic resonance imaging and computed tomography scan of her liver, which did not reveal the source of her liver enlargement. Due to her progressive liver enlargement and insufficiency, she developed a life-threatening esophageal variceal bleeding during her hospital stay which further delayed the attainment of her diagnosis. She finally underwent a videoscopic laparotomy and liver biopsy which revealed complete replacement and filling in of the liver sinuous with Indian filing lobular breast cancer. The patient died shortly after her diagnosis and before she could be discharged. In Case 2, a 68-year-old Caucasian woman with non-small-cell lung cancer was admitted to our Oncology in-patient service with a presentation of rapid hepatic insufficiency and severe liver enlargement. Like the patient in Case 1, during her hospitalization, this patient underwent a thorough radiographic evaluation, including computed tomography and magnetic resonance imaging, to identify the source of her symptoms. Radiographic imaging showed only hepatomegaly and no discrete focal lesions. As the multiple imaging studies over a period of a week did not reveal a clear cause for her symptoms, she finally underwent an interventional radiology core biopsy which showed complete replacement of her liver with non-small-cell lung cancer. Her condition rapidly progressed due to continued liver enlargement and she died due to frank liver failure before her diagnosis was affirmed and she could be discharged. Conclusion

    Purpose: To demonstrate that margins of each pelvic chain may be derived by verifying the bony and soft tissue structures around abnormal nodes on computed tomography (CT) slices. Methods and Materials: Twenty consecutive patients (16 males, 4 females; mean age, 66 years; range, 43-80 years) with radiologic diagnosis of nodal involvement by histologically proved cervix carcinoma (two), rectum carcinoma (three), prostate carcinoma (four), lymphoma (five), penis carcinoma (one), corpus uteri carcinoma (one), bladder carcinoma (two), cutis tumor (one), and soft-tissue sarcoma (one) were retrospectively reviewed. One hundred CT scans showing 85 enlarged pelvic nodes were reviewed by two radiation oncologists (M.P., S.B.), and two radiologists (C.P., G.A.). Results: The more proximal structures to each enlarged node or group of nodes were thus recorded in a clockwise direction. Conclusion: According to their frequency and visibility, craniocaudal, anterior, lateral, posterior and medial margins of common iliac, external and internal iliac nodal chains, obturator and pudendal nodes, and deep and superficial inguinal nodes were derived from CT observations

    Gynecomastia is defined as a palpable enlargement of the mammary gland in males that is distinguishable from lipomastia. The aim of this study was to assess the prevalence and characteristics of different causes of breast enlargement in young males referred to our tertiary center, and evaluation of the factors associated with gynaecomastia. One hundred thirty-five male recruits aged 20-30 years were enrolled in the study. A control group comprising 32 age-matched healthy individuals aged 20-25 years was also studied. Idiopathic gynecomastia (IG) was diagnosed in 31 of 135 patients (23%) and Klinefelter' syndrome (KS) was diagnosed in 70 cases (52%). Patients with KS had significantly higher body mass index (BMI) and waist and hip circumference waist/hip ratio than the control group. FSH, LH and SHBG were significantly higher and DHEAS, free testosterone (fT) and total testosterone (tT) were lower in patients with KS than the control group. Anthropometric measurements revealed significant increase in body weight and BMI in patients with IG compared with healthy controls. FSH and LH levels were significantly higher in the patients with IG. Patients with pseudogynecomastia alone were not obese and hypogonadism was observed in 35.1% of patients. We concluded that gynaecomastia in young adult males is mostly because of KS or idiopathic in origin. IG seems to be the result of androgen resistance and in part increased aromatization because of increased adiposity. Symptoms or findings for hypogonadism must be evaluated carefully in patients with pseudogynecomastia. We also suggest that the presence of both gynecomastia and azoospermia necessitate further karyotypic analyses for KS.

    Enlargement is often regarded as an elite-driven process, which does not or not sufficiently include the views of ordinary citizens. At the same time, support for integration has been eroding over the last decade, contributing to a public-elite gap in preferences towards the process. This paper

    Wright, William B.

    2002-01-01

    A research project is underway at NASA Glenn to produce a computer code which can accurately predict ice growth under a wide range of meteorological conditions for any aircraft surface. This report will present a description of the code inputs and outputs from version 2.2.2 of this code, which is called LEWICE. This version differs from release 2.0 due to the addition of advanced thermal analysis capabilities for de-icing and anti-icing applications using electrothermal heaters or bleed air applications. An extensive effort was also undertaken to compare the results against the database of electrothermal results which have been generated in the NASA Glenn Icing Research Tunnel (IRT) as was performed for the validation effort for version 2.0. This report will primarily describe the features of the software related to the use of the program. Appendix A of this report has been included to list some of the inner workings of the software or the physical models used. This information is also available in the form of several unpublished documents internal to NASA. This report is intended as a replacement for all previous user manuals of LEWICE. In addition to describing the changes and improvements made for this version, information from previous manuals may be duplicated so that the user will not need to consult previous manuals to use this code.

  10. Electric Chern-Simons term, enlarged exotic Galilei symmetry and noncommutative plane

    International Nuclear Information System (INIS)

    Olmo, Mariano A. del; Plyushchay, Mikhail S.

    2006-01-01

    The extended exotic planar model for a charged particle is constructed. It includes a Chern-Simons-like term for a dynamical electric field, but produces usual equations of motion for the particle in background constant uniform electric and magnetic fields. The electric Chern-Simons term is responsible for the noncommutativity of the boost generators in the 10-dimensional enlarged exotic Galilei symmetry algebra of the extended system. The model admits two reduction schemes by the integrals of motion, one of which reproduces the usual formulation for the charged particle in external constant electric and magnetic fields with associated field-deformed Galilei symmetry, whose commuting boost generators are identified with the nonlocal in time Noether charges reduced on-shell. Another reduction scheme, in which electric field transmutes into the commuting space translation generators, extracts from the model a free particle on the noncommutative plane described by the twofold centrally extended Galilei group of the nonrelativistic anyons

    The GOODS-MUSIC multiwavelength catalog provides photometric and spectroscopic information for galaxies in the GOODS Southern field. It includes two U images obtained with the ESO 2.2m telescope and one U band image from VLT-VIMOS, the ACS-HST images in four optical (B,V,i,z) bands, the VLT-ISAAC J, H, and Ks bands as well as the Spitzer images at 3.6, 4.5, 5.8, and 8 micron (IRAC) and 24 micron (MIPS). Most of these images have been made publicly available in the coadded version by the GOODS team, while the U band data were retrieved in raw format and reduced by our team. We also collected all the available spectroscopic information from public spectroscopic surveys and cross-correlated the spectroscopic redshifts with our photometric catalog. For the unobserved fraction of the objects, we applied our photometric redshift code to obtain well-calibrated photometric redshifts. The final catalog is made up of 15208 objects, with 209 known stars and 61 AGNs. The major new feature of this updated release is the inclusion of 24 micron photometry. Further improvements concern a revised photometry in the four IRAC bands (mainly based on the use of new PSF-matching kernerls and on a revised procedure for estimating the background), the enlargement of the sample of galaxies with spectroscopic redshifts, the addition of objects selected on the IRAC 4.5 micron image and a more careful selection of AGN sources.

  13. 'The surface management system' (SuMS) database: a surface-based database to aid cortical surface reconstruction, visualization and analysis

    Science.gov (United States)

    Dickson, J.; Drury, H.; Van Essen, D. C.

    2001-01-01

    Surface reconstructions of the cerebral cortex are increasingly widely used in the analysis and visualization of cortical structure, function and connectivity. From a neuroinformatics perspective, dealing with surface-related data poses a number of challenges. These include the multiplicity of configurations in which surfaces are routinely viewed (e.g. inflated maps, spheres and flat maps), plus the diversity of experimental data that can be represented on any given surface. To address these challenges, we have developed a surface management system (SuMS) that allows automated storage and retrieval of complex surface-related datasets. SuMS provides a systematic framework for the classification, storage and retrieval of many types of surface-related data and associated volume data. Within this classification framework, it serves as a version-control system capable of handling large numbers of surface and volume datasets. With built-in database management system support, SuMS provides rapid search and retrieval capabilities across all the datasets, while also incorporating multiple security levels to regulate access. SuMS is implemented in Java and can be accessed via a Web interface (WebSuMS) or using downloaded client software. Thus, SuMS is well positioned to act as a multiplatform, multi-user 'surface request broker' for the neuroscience community.

  14. CLIPS - C LANGUAGE INTEGRATED PRODUCTION SYSTEM (MACINTOSH VERSION)

    Science.gov (United States)

    Culbert, C.

    1994-01-01

    The C Language Integrated Production System, CLIPS, is a shell for developing expert systems. It is designed to allow artificial intelligence research, development, and delivery on conventional computers. The primary design goals for CLIPS are portability, efficiency, and functionality. For these reasons, the program is written in C. CLIPS meets or outperforms most micro- and minicomputer based artificial intelligence tools. CLIPS is a forward chaining rule-based language. The program contains an inference engine and a language syntax that provide a framework for the construction of an expert system. It also includes tools for debugging an application. CLIPS is based on the Rete algorithm, which enables very efficient pattern matching. The collection of conditions and actions to be taken if the conditions are met is constructed into a rule network. As facts are asserted either prior to or during a session, CLIPS pattern-matches the number of fields. Wildcards and variables are supported for both single and multiple fields. CLIPS syntax allows the inclusion of externally defined functions (outside functions which are written in a language other than CLIPS). CLIPS itself can be embedded in a program such that the expert system is available as a simple subroutine call. Advanced features found in CLIPS version 4.3 include an integrated microEMACS editor, the ability to generate C source code from a CLIPS rule base to produce a dedicated executable, binary load and save capabilities for CLIPS rule bases, and the utility program CRSV (Cross-Reference, Style, and Verification) designed to facilitate the development and maintenance of large rule bases. Five machine versions are available. Each machine version includes the source and the executable for that machine. The UNIX version includes the source and binaries for IBM RS/6000, Sun3 series, and Sun4 series computers. The UNIX, DEC VAX, and DEC RISC Workstation versions are line oriented. The PC version and the Macintosh

  20. The “transforming power” of EU Enlargement policy in Serbia. An anthropological reflection

    Directory of Open Access Journals (Sweden)

    Francesco Florindi

    2012-05-01

    Full Text Available The enlargement process of the European Union contributed substantially to the harmonisation of legal systems over the continent. The article provides an anthropological critique to the way harmonisation to EU law is implemented in the Balkans, underlining the general lack of awareness by both Serbian government and the EU of Serbian social and legal systems. While applying the anthropological method to EU law’s effects in Serbia, the author investigates also the inner value of the EU project itself. For instance the State's failure to regulate anti-corruption matters has been experienced even when the State's provision in question were in full compliance with several other international obligations and with a positively hierarchically superior legal system: the Constitution.

  1. Radiation-induced enlargement of granulocytic and macrophage progenitor cells in mouse bone marrow

    Energy Technology Data Exchange (ETDEWEB)

    Metcalf, D; Johnson, G R; Wilson, J [Walter and Eliza Hall Inst. of Medical Research, Parkville (Australia)

    1977-01-01

    The peak sedimentation velocity of C/sub 57/BL mouse bone marrow progenitors of granulocytes and macrophages (GM-colony-forming cells, GM-CFC's) increased from 4.3 mm/h to 7 to 8 mm/h by 2 days after 250 rad whole body irradiation and slowly returned to normal over the next 3 weeks. Preliminary irradiation and/or endotoxin injection did not prevent this radiation-induced change. Some change in sedimentation velocity was seen with as little as 100 rad irradiation. Neither buoyant density nor cell cycle changes could account for the sedimentation velocity data which therefore indicate a major volume increase in the GM-CFC's. This size enlargement affected all subpopulations of GM-CFC's which consequently maintained their size relationship with one another.

  2. Subcooled He II heat transport in the channel with abrupt contractions/enlargements

    International Nuclear Information System (INIS)

    Maekawa, R.; Iwamoto, A.; Hamaguchi, S.; Mito, T.

    2002-01-01

    Heat transport mechanisms for subcooled He II in the channel with abrupt contractions and/or enlargements have been investigated under steady state conditions. The channel, made of G-10, contains various contraction geometries to simulate the cooling channel of a superconducting magnet. In other words, contractions are periodically placed along the channel to simulate the spacers within the magnet winding. A copper block heater inputs the heat to the channel from one end, while the other end is open to the He II bath. Temperature profiles were measured with temperature sensors embedded in the channel as a function of heat input. Calculations were performed using a simple one-dimensional turbulent heat transport equation and with geometric factor consideration. The effects on heat transport mechanisms in He II caused by abrupt change of channel geometry and size are discussed

  3. Size enlargement of radioactive and hazardous species and their separation by microfiltration and ultrafiltration membranes

    International Nuclear Information System (INIS)

    1993-01-01

    Separation and volume reduction of aqueous solutions involving membranes is evolving into an expanding and diversified field. Numerous commercially successful membranes and their applications are now available. Among different driving forces used in membrane separation, pressure-driven separation has gained wide application. Depending on the size of the dissolved species in solution to be separated, the pressure needed to achieve the desired separation varies. The microfiltration and ultrafiltration membrane systems are low-pressure processes that generally operate below 350 kPa. To exploit these membranes in applications involving the removal of dissolved contaminants from solutions, it is essential to create a suitable size for the dissolved contaminants, so that the membranes can effectively retain them while producing a filtrate stream essentially free of contaminants. Size enlargement of the dissolved contaminants can be achieved through solution conditioning with the addition of one or a combination of chemical reagents and powdered materials. Examples of typical additives include: pH chemicals, polyelectrolytes, microorganisms and powdered adsorption/ion-exchange materials. In many situations, adequate control and optimization of the system chemistry and hydraulic conditions provide high selectivity and efficiency for contaminant removal. This paper summarizes removal efficiency data for cadmium, lead, mercury, uranium, arsenic, strontium-90/85, cesium-137 and iron. These data resulted from various initiatives on membrane technology undertaken during the past five years by the Waste Processing Technology group at Chalk River Laboratories. The technology involves size enlargement of contaminants present in waste solution, and their separation using either microfiltration or ultrafiltration. The data support remedial applications involving treatment of contaminated groundwater and soils

  4. Polychlorinated biphenyls exposure-induced insulin resistance is mediated by lipid droplet enlargement through Fsp27.

    Although epidemiological and experimental studies demonstrated that polychlorinated biphenyls (PCBs) lead to insulin resistance, the mechanism underlying PCBs-induced insulin resistance has remained unsolved. In this study, we examined in vitro and in vivo effects of PCB-118 (dioxin-like PCB) and PCB-138 (non-dioxin-like PCB) on adipocyte differentiation, lipid droplet growth, and insulin action. 3T3-L1 adipocytes were incubated with PCB-118 or PCB-138 during adipocyte differentiation. For in vivo studies, C57BL/6 mice were administered PCB-118 or PCB-138 (37.5 mg/kg) by intraperitoneal injection and we examined adiposity and whole-body insulin action. PCB-118 and PCB-138 significantly promoted adipocyte differentiation and increased the lipid droplet (LD) size in 3T3-L1 adipocytes. In mice, both PCBs increased adipose mass and adipocyte size. Furthermore, both PCBs induced insulin resistance in vitro and in vivo. Expression of fat-specific protein 27 (Fsp27), which is localized to LD contact sites, was increased in PCB-treated 3T3-L1 adipocytes and mice. Depletion of Fsp27 by siRNA resulted in the inhibition of LD enlargement and attenuation of insulin resistance in PCB-treated 3T3-L1 adipocytes. An anti-diabetic drug, metformin, attenuated insulin resistance in PCB-treated 3T3-L1 adipocytes through the reduced expression of Fsp27 protein and LD size. This study suggests that PCB exposure-induced insulin resistance is mediated by LD enlargement through Fsp27.

    Moxibustion, a form of traditional Chinese medicine (TCM), is the burning of the herb moxa (Folium Artemisiae argyi or mugwort) over acupuncture points. It is often used in China to facilitate cephalic version of breech presentation. This article reviews the history, philosophy, therapeutic use, possible mechanisms of action, and literature pertaining to its use for this indication. For moxibustion, moxa can be rolled into stick form, placed directly on the skin, or placed on an acupuncture needle and ignited to warm acupuncture points. Studies have demonstrated that moxibustion may promote cephalic version of breech presentation and may facilitate external cephalic version. However, there is currently a paucity of research on the effects of moxibustion on cephalic version of breech presentation, and thus there is a need for further studies. Areas needing more investigation include efficacy, safety, optimal technique, and best protocol for cephalic version of breech presentation. © 2018 by the American College of Nurse-Midwives.

    Using four large-scale simulated landfill equipments, indoor parallel simulation landfill experiment was carried out. By monitoring the cumulative settlement of MSW, comparable researches indicate the actual effects of 'empirical model' and 'biodegradation model' on landfill surface settlement forecast, and the optimization measures are proposed on the basis of model defects analysis. Research leaded to following results: To the short-term prediction of MSW settlement, two types of models all have satisfactory predictive validity. When performing medium and long-term prediction, 'empirical model' predicted a significant deviation from the actual, and the forecasting error of 'biodegradation model' is also gradually enlarge with the extending forecast period. For optimizing these two types of model, long-term surface settlement monitoring is fundamental method, and constantly modify the model parameters is the key according to the dynamic monitoring data.

    Non-Hodgkin's lymphoma (NHL) is the fourth most common childhood malignancy. Uterine involvement with NHL is well described in adults, rare in children and has not been described in the first 2 years of life. While renal involvement in NHL is well recognised, diffuse renal enlargement is an uncommon finding. We report a unique case of B-cell lymphoma of primitive phenotype in a 15-month-old girl with uterine and renal involvement at presentation. We describe the US and MRI features at presentation that helped in the prospective diagnosis of this condition. (orig.)

    IceCube is a neutrino observatory located at the geographic South Pole. The main backgrounds for IceCube's primary goal, the measurement of astrophysical neutrinos, are muons and neutrinos from cosmic-ray air showers in the Earth's atmosphere. Strong supression of these backgrounds from the Southern hemisphere has been demonstrated by coincident detection of these air showers with the IceTop surface detector. For an extended instrument, IceCube-Gen2, it is considered to build an enlarged surface array, IceVeto, that will improve the detection capabilities of coincident air showers. We will present simulation studies to estimate the IceVeto capabilities to optimize the IceCube-Gen2 design.

  15. Gingival enlargement as an early diagnostic indicator in therapy-related acute myeloid leukemia: A rare case report and review of literature

    Directory of Open Access Journals (Sweden)

    Triveni M Gowda

    2013-01-01

    Full Text Available Treatment for Hodgkin′s lymphoma (HL has resulted in excellent survival rates but is associated with increased risks of secondary therapy-related acute myeloid leukemia (t-AML. Gingival enlargement associated with bleeding and ulceration is the most common rapidly appearing oral manifestations of leukemic involvement. An 8 months pregnant patient reported with generalized gingival enlargement, with localized cyanotic and necrotic papillary areas. Co-relating the hematological report with the oral lesions and her past medical history of HL, a diagnosis of t-AML secondary to treatment for HL was made by the oncologist. As oral lesions are one of the initial manifestations of acute leukemia, they may serve as a significant diagnostic indicator for the dental surgeons and their important role in diagnosing and treating such cases. Furthermore, this case report highlights the serious complication of t-AML subsequent to HL treatment and the important role that a general and oral health care professional may play in diagnosing and treating such cases.

  16. User's manual, version 1.00 for Monteburns, version 3.01

    International Nuclear Information System (INIS)

    Poston, D.I.; Trellue, H.R.

    1998-06-01

    Monteburns is a fully automated tool that links the Monte Carlo transport code MCNP with the radioactive decay and burnup code ORIGEN2. Monteburns produces a large number of criticality and burnup results based on various material feed/removal specifications, power(s), and time intervals. The program processes input from the user that specifies the system geometry, initial material compositions, feed/removal specifications, and other code-specific parameters. Various results from MCNP, ORIGEN2, and other calculations are then output successively as the code runs. The principle function of monteburns is to transfer one-group cross section and flux values from MCNP to ORIGEN2, and then transfer the resulting material compositions (after irradiation and/or decay) from ORIGEN2 back to MCNP in a repeated, cyclic fashion. The basic requirement of the code is that the user have a working MCNP input file and other input parameters; all interaction with ORIGEN2 and other calculations are performed by monteburns. This report serves as a user's manual for monteburns. It describes how the code functions, what input the user must provide, the calculations performed by the code, and it presents the format required for input files, as well as samples of these files. Monteburns is still in a developmental stage; thus, additions and/or changes may be made over time, and the user's manual will change as well. This is the first version of the user's manual (valid for monteburns version 3.01); users should contact the authors to inquire if a more recent version is available

Cellulose is synthesized by complexes in the plasma membrane and is extruded as a self-assembling microfibril, whereas the matrix polymers are secreted by the Golgi apparatus and become integrated into the wall network by poorly understood mechanisms. The growing wall is under high tensile stress from cell turgor and is able to enlarge by a combination of stress relaxation and polymer creep. A pH-dependent mechanism of wall loosening, known as acid growth, is characteristic of growing walls and is mediated by a group of unusual wall proteins called expansins. Expansins appear to disrupt the noncovalent bonding of matrix hemicelluloses to the microfibril, thereby allowing the wall to yield to the mechanical forces generated by cell turgor. Other wall enzymes, such as (1-->4) beta-glucanases and pectinases, may make the wall more responsive to expansin-mediated wall creep whereas pectin methylesterases and peroxidases may alter the wall so as to make it resistant to expansin-mediated creep.

    Internally cooled X-ray optics, like X-ray monochromators and reflecting X-ray mirrors, play a crucial role in defining a beamlines resolution, degree of coherence and flux. A great effort is invested in the development of these optical components. An important aspect of the functionality of high heat load optics is its cooling and its influence on surface deformation. The authors present a study of two different geometrical cooling approaches. Its influence on beam inhomogeneity due to the strain from the manufacturing process is presented. X-ray topographic images and FWHM measurements are presented. FEA simulations of cooling efficiency and surface deformations were performed. The best achieved results are under an enlargement of 0.4μrad of the measured rocking curve

    This article takes a look at the project concerned with enlarging the storage lake near the Grimsel Pass in the Swiss Alps. The enlargement of the existing lake by increasing the height of the dams is the central element of a larger project involving the optimisation of the hydropower scheme in the area. The history of the hydropower scheme is briefly looked at and the aims of the project are explained. Environmental aspects are examined and the economic implications and benefits for this mountainous area in the Alps are discussed. The diversion of the important tourist route over the pass and the new suspension bridge over the lake that is planned are also described. The project is compared with the previously planned 'Grimsel West' project. The ecological improvements associated with the new project are discussed. Arguments brought up against the project are countered.

  3. Endolymphatic Sac Enlargement in a Girl with a Novel Mutation for Distal Renal Tubular Acidosis and Severe Deafness

    Full Text Available Hereditary distal renal tubular acidosis (dRTA is caused by mutations of genes encoding subunits of the H+-ATPase (ATP6V0A4 and ATP6V1B1 expressed in α-intercalated cells of the distal renal tubule and in the cochlea. We report on a 2-year-old girl with distal RTA and profound speech delay which was initially misdiagnosed as autism. Genetic analysis showed compound heterozygous mutations with one known and one novel mutation of the ATP6V1B1 gene; cerebral magnetic resonance imaging (MRI revealed bilateral enlargement of the endolymphatic sacs of the inner ear. With improved cooperation, audiometric testing showed that hearing loss was most profound on the right, where endolymphatic sac enlargement was greatest, demonstrating a clear link between the degree of deafness and the degree of inner ear abnormality. This case indicates the value of MRI for diagnosis of inner ear involvement in very young children with distal RTA. Although citrate therapy quickly corrects the acidosis and restores growth, early diagnosis of deafness is crucial so that hearing aids can be used to assist acquisition of speech and to provide enough auditory nerve stimulation to assure the affected infants remain candidates for cochlear implantation.

    Enlarged vestibular aqueduct (EVA) is the most common inner ear malformation. While a strong correlative relationship between EVA and hearing loss is well established, its association with vestibular dysfunction is less well understood. In this study, we examine the effects of EVA on the vestibular system in patients with EVA. Prospective, cross-sectional study of a cohort ascertained between 1999 and 2013. National Institutes of Health Clinical Center, a federal biomedical research facility. In total, 106 patients with unilateral or bilateral EVA, defined as a midpoint diameter greater than 1.5 mm, were referred or self-referred to participate in a study of the clinical and molecular aspects of EVA. Clinical history was ascertained with respect to the presence or absence of various vestibular signs and symptoms and history of head trauma. Videonystagmography (VNG), cervical vestibular evoked myogenic potential (cVEMP), and rotational vestibular testing (RVT) were performed to assess the vestibular function. Of the patients with EVA, 45% had vestibular signs and symptoms, and 44% of tested patients had abnormal VNG test results. An increased number of vestibular signs and symptoms was correlated with the presence of bilateral EVA (P = .008) and a history of head injury (P VNG results also correlated with a history of head injury (P = .018). Vestibular dysfunction is common in patients with EVA. However, not all patients with vestibular signs and symptoms have abnormal vestibular test results. Clinicians should be aware of the high prevalence of vestibular dysfunction in patients with EVA. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2015.

    We previously demonstrated the super-induced expression of the Grin2c gene encoding the N-methyl-D-aspartate receptor 2C subunit during the development of liver enlargement with hepatocellular hypertrophy induced by phenobarbital, clofibrate, or piperonyl butoxide. In the present study, we assessed whether or not Grin2c gene expression was induced during the development of chemically induced liver enlargement with hyperplasia. Male Sprague-Dawley (SD) rats, stroke-prone spontaneously hypertensive rats (SHRSPs), and SHRSP's normotensive control, Wistar-Kyoto (WKY) rats, were administered lead nitrate (LN) (0.1 mmol/kg, single i.v.), a direct inducer of liver hyperplasia, and changes in the level of Grin2c mRNA in the liver were assessed by real-time RT-PCR. The level of hepatic Grin2c mRNA was significantly higher 6-48 hr after the injection in SD rats (about 30~40- and 70-fold over the control at 6~24 hr and 48 hr, respectively) and in WKY rats (about 20-fold over the control only at 12 hr), but was not significantly higher in SHRSPs. Such differences in LN-induced levels of Grin2c mRNA among SD rats, WKY rats, and SHRSPs were closely correlated with those in the previously reported increase in liver weight 48 hr after LN administration. The present findings suggest that the increase in the level of hepatic Grin2c mRNA relates to development of chemically induced liver enlargement with hyperplasia.

  15. Coupling between bulk ordering and surface segregation: from alloy surfaces to surface alloys

    International Nuclear Information System (INIS)

    Gallis, Coralie

    1997-01-01

    -The knowledge of the alloy surfaces is of prime interest to understand their catalytic properties. On the one hand, the determination of the stability of the surface alloys depends very strongly on the behaviours of the A c B 1-c alloy surfaces. On the other hand, the knowledge of the kinetics of the formation-dissolution of surface alloys can allow to understand the equilibrium segregation isotherm. We have then studied the relation between the equilibrium surface segregation in an alloy A c B 1-c and the kinetics of dissolution of a few metallic layers of A/B and the inverse deposit. We have used an energetic model derived from the electronic structure (T.I.B.M.) allowing us to study the surface segregation both in the disordered state and in the ordered one. The kinetics of dissolution were studied using the kinetic version of this model (K.T.I.B.M.) consistent with the equilibrium model. To illustrate our study, we have chosen the Cu-Pd system, a model for the formation of surface alloys and for which a great number of studies, both experimental and theoretical, are in progress. We then have shown for the (111) surface of this system that the surface alloys obtained during the dissolution are related to the alloy surfaces observed for the equilibrium segregation. The Cu-Pd system is characteristic of systems which have a weak segregation energy. Then, we have performed an equivalent study for a system with a strong segregation energy. Our choice was directly put on the Pt-Sn system. The surface behaviour, both in equilibrium and during the kinetics of dissolution, is very different from the Cu-Pd case. In particular, we have found pure 2-D surface alloys. Finally, a quenched molecular dynamics study has allowed us to determine the relative stability of various possible surface superstructures.

    The Swedish Nuclear Fuel and Waste Management Company (SKB) is undertaking site characterisation at two different locations, the Forsmark and Simpevarp areas, with the objective of siting a geological repository for spent nuclear fuel. An integrated component in the characterisation work is the development of a site descriptive model that constitutes a description of the site and its regional setting, covering the current state of the geosphere and the biosphere as well as those ongoing natural processes that affect their long-term evolution. The present report documents the site descriptive modelling activities (version 1.2) for the Forsmark area. The overall objectives of the version 1.2 site descriptive modelling are to produce and document an integrated description of the site and its regional environments based on the site-specific data available from the initial site investigations and to give recommendations on continued investigations. The modelling work is based on primary data, i.e. quality-assured, geoscientific and ecological field data available in the SKB databases SICADA and GIS, available July 31, 2004. The work has been conducted by a project group and associated discipline-specific working groups. The members of the project group represent the disciplines of geology, rock mechanics, thermal properties, hydrogeology, hydrogeochemistry, transport properties and surface ecosystems (including overburden, surface hydrogeochemistry and hydrology). In addition, some group members have specific qualifications of importance in this type of project e.g. expertise in RVS (Rock Visualisation System) modelling, GIS-modelling and in statistical data analysis. The overall strategy to achieve a site description is to develop discipline-specific models by interpretation and analyses of the primary data. The different discipline-specific models are then integrated into a site description. Methodologies for developing the discipline-specific models are documented in

    This report includes a comprehensive manual of the computer program PROSA which illustrate the handling and functioning of PROSA. The manual PROSA 4.0 (FORTRAN 77) describes the PC Version of PROSA including its program moduls. The PROSA program package is a statistical tool to decide on the basis of statistical assumptions whether in a given sequence of material balance periods a loss of material might have occurred. The evaluation of the material balance data is based on statistical test procedures. In the present PROSA Version 4.0 the three tests CUMUF test, PAGE's test and GEMUF test are applied to a sequence of material balances. PROSA Version 4.0 supports a real sequential evaluation. That means, PROSA is not only able to evaluate a series of MUF values sequentially after the campaign has finished, but also real sequentially during the campaign. PROSA Version 4.0 is a menu-guided computer program. Data input can be performed either by diskette or by key-enter. Result output is primarily an information whether or not an alarm is indicated. This information can be displayed either numerically or graphically. Therefore, a comfortable graphical output utility is attached to PROSA 4.0. The program moduls are compiled and linked with the Ryan Mc-Farland Compiler. The PROSA graphical utility uses the PLOT88 Library of Plotworks, Inc. (orig./HP) [de
