    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.

    Full Text Available Mouth floor enlargements (MFE are observed in edentulous and partially edentulous patients, impairing denture fitting, and have recently been described in the literature as hyperplasias of the sublingual glands. OBJECTIVE: This study aims at describing the microscopic aspects of MFE that contribute to their final diagnosis. METHODS: Twenty-four specimens were surgically removed from the enlarged mouth floor of 19 patients (15 females and 4 males. Patient age ranged from 48 to 74 years, with a mean of 57 years. The main surgical indication was to permit or improve the fitting of dentures. Six patients were completely edentulous and 13 were partially edentulous. The material was processed for microscopic examination and stained with hematoxylin-eosin, Mallory's trichrome and periodic-acid Schiff (PAS. RESULTS AND CONCLUSIONS: The epithelium of the mouth floor was normal in 17 cases, hyperplastic in 4 and atrophic in 3. Six of the 24 sublingual glands removed were microscopically normal, while the other specimens presented acinar atrophy with hyperplasia of duct-like structures. Interstitial fibrosis was observed in 18 cases and was accompanied by adipose tissue infiltration in 15. Decreased lymphoid tissue was observed in 16 samples and oncocytosis was present in 5 cases. We suggest that MFE in edentulous or partially edentulous patients should be considered as an entity for the text books.Tumefações do soalho bucal (TSB são observadas em pacientes edêntulos ou parcialmente edêntulos, prejudicando a adaptação de próteses, e têm sido descritas recentemente na literatura como hiperplasias das glândulas sublinguais.

    2018-03-01

    Conclusions and importance: This is the first account of chorioretinal fold formation by severely enlarged lacrimal glands appearing in IgG4-related dacryoadenitis. Chorioretinal fold formation by an enlarged lacrimal gland occurring bilaterally may represent a basis for suspecting IgG4-related dacryoadenitis. Prompt treatment is recommended for patients presenting with very large lacrimal glands to avoid visual impairment.

  5. EU Enlargement

    Pedersen, Peder J.; Pytlikova, Mariola

    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...

  11. Effects of space allowance and earthen floor on welfare-related physiological and behavioural responses in male blue foxes.

    Korhonen, H; Niemelä, P; Jauhiainen, L; Tupasela, T

    Welfare-related physiological and behavioural responses were studied in farm-bred male blue foxes (Alopex lagopus). Three different-sized cages (80-cm long [CL80], 120-cm long [CL120], and 240-cm long [CL240]; each 105-cm wide x 70-cm high) with wire-mesh floors and one enlarged cage (CL240E) with both wire-mesh floor (240-cm long x 105-cm wide x 70-cm high) and earthen floor (80-cm long x 105-cm wide x 70-cm high) were compared. N = 30 males for each group. The experiments lasted from weaning in July to pelting in December. Statistical analyses were based on the models accounting for litter as a block effect. Breaking strength of tibia was highest for foxes having access to both wire-mesh and ground floors (CL240E). Stress-induced hyperthermia was evident during capture and immobilisation. The highest rectal temperature (mean +/- SEM) was found in CL240E (capture: 39.6 +/- 0.09 degrees C, restraint:40.0 +/- 0.09 degrees C) and the lowest in CL80 (capture: 39.1 +/- 0.09 degrees C, restraint: 39.7 +/- 0.09 degrees C). Likewise, capture time (median; interquartile range) in the home cage was highest in CL240E (29; 18 to 44) and lowest in CL80 (12; 9 to 14). During capture, foxes tended to withdraw to the farthest site within the cage. CL240E foxes typically showed the most fear towards human. The most confident animals were found in CL80. The cortisol:creatinine ratio (median; interquartile range) obtained from circadian urine did not reveal statistically significant differences among CL80 (3. 5; 2.6 to 4.1), CL120 (2.3; 1.5 to 3.8) and CL240 (2.3, 1.5 to 3.7). The earthen flooring complicated the urine sampling and conclusions for CL240E (1.7; 1.2 to 2.2). CL240E foxes were the most active and explorative on both wire-mesh- and ground-floored open-field arenas. Altogether, 53% of furs from CL240E were classified as very dirty. Dirtiness of furs in other test groups was slight. In conclusion, the present results did not reveal an unambiguous superiority of any of the

  12. Comparative evaluation of oral hygiene status and gingival enlargement among epileptic and healthy children as related to various antiepileptic drugs

    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.

  13. Outer retinal tubulation as a predictor of the enlargement amount of geographic atrophy in age-related macular degeneration.

    2015-02-01

    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

  14. Low-Impact Flooring: Does It Reduce Fall-Related Injuries?

    Hanger, H Carl

    2017-07-01

    To compare fall rates and injuries from falls on low-impact flooring (LIF) compared with a standard vinyl flooring. Prospective, observational, nonrandomized controlled study. Subacute Older Persons Health ward (N = 20 beds). Older inpatients. Three different types of LIF. All falls in the ward were prospectively monitored using incident reporting, noting location and consequences of each fall. Fall rates (per 1000 bed days) and injuries, were compared between bedroom falls on LIF against those occurring on standard vinyl flooring (controls). Over 31 months, there were 278 bedroom falls (from 178 fallers). The bedroom fall rate (falls per 1000 bed days occupied) did not differ between the LIF and control groups (median 15 [IQR 8-18] versus 17 [IQR 9-23], respectively; P = .47). However, fall-related injuries were significantly less frequent when they occurred on LIFs (22% of falls versus 34% of falls on control flooring; P = .02). Fractures occurred in 0.7% of falls in the LIF cohort versus 2.3% in the control cohort. Rolling resistance when moving heavier equipment, such as beds or hoists, was an issue for staff on LIF. LIF significantly reduced fall-related injuries compared with a standard vinyl flooring, whereas they did not alter the overall risk of falling.

  15. PVC flooring is related to human uptake of phthalates in infants.

    Carlstedt, F; Jönsson, B A G; Bornehag, C-G

    2013-02-01

    Polyvinyl chloride (PVC) flooring material contains phthalates, and it has been shown that such materials are important sources for phthalates in indoor dust. Phthalates are suspected endocrine-disrupting chemicals (EDCs). Consecutive infants between 2 and 6 months old and their mothers were invited. A questionnaire about indoor environmental factors and family lifestyle was used. Urinary metabolites of the phthalates diethyl phthalate (DEP), dibutyl phthalate (DBP), butylbenzyl phthalate (BBzP), and dietylhexyl phthalate (DEHP) were measured in the urine of the children. Of 209 invited children, 110 (52%) participated. Urine samples were obtained from 83 of these. Urine levels of the BBzP metabolite monobenzyl phthalate (MBzP) was significantly higher in infants with PVC flooring in their bedrooms (P flooring material may increase the human uptake of phthalates in infants. Urinary levels of phthalate metabolites during early life are associated with the use of PVC flooring in the bedroom, body area, and the use of infant formula. This study shows that the uptake of phthalates is not only related to oral uptake from, for example, food but also to environmental factors such as building materials. This new information should be considered when designing indoor environment, especially for children. © 2012 John Wiley & Sons A/S.

  17. The European Commission in the power relations of the European Union after the 2004–07 enlargement

    Ekaterina Ostrovskaya

    2014-05-01

    Full Text Available pplying a comparative perspective, this article argues that the current crisis of European Union integration cannot be resolved by member states either transferring additional competences to the EU level or strengthening the intergovernmental dimension of integration. The systemic character of the ongoing process is weakening the institutional structure, which affects both the institutions and their power relations. The European Commission (EC, once a highly independent supranational actor on the eve of the integration process in the 1950s, now faces growing competition from intergovernmental elements in the institutional balance. The theoretical approach of historical neo-institutionalism offers new, useful insights into this research area. The articles uses this theory to analyze the EC’s evolution since the time of its creation in the form of the High Authority of the European Coal and Steel Community, focusing on the links between the gradual changes in its internal structure and its institutional position. Although the phenomenon of “path dependence” was initially present in the EC’s internal systems, the later development of its competences in the institutional balance provoked member states to limit the commission’s activities in the second half of the 1960s. First attempts were made mainly by appointing weak presidents, but the later reform of the EC’s internal structure, undertaken by Neil Kinnock in the beginning of the 21st centry, directed its further structural development as a more technocratic institution. Consequently, the EC was not able to pursue its aims effectively in preparing for its enlargement to include Central and Eastern Europe. The increased heterogeneity of the member states after the 2004–07 enlargement also weakened the EC’s position in the institutional balance, diminishing its traditional function as the “engine of integration.”

  18. Compliant flooring to prevent fall-related injuries: a scoping review protocol.

    Lachance, Chantelle C; Jurkowski, Michal P; Dymarz, Ania C; Mackey, Dawn C

    2016-08-16

    Fall-related injuries can have serious consequences for older adults, including increased risk of dependence in daily activities and mortality. Compliant flooring is a passive intervention that may reduce the incidence and severity of fall-related injuries in healthcare settings, including acute and long-term care, but few sites have implemented compliant flooring, in part because synthesised evidence about key performance aspects has not been available. We will conduct a scoping review to address the question: what is presented about the biomechanical efficacy, clinical effectiveness, cost-effectiveness, and workplace safety associated with compliant flooring systems that aim to prevent fall-related injuries? We will conduct a comprehensive and systematic literature search of academic databases (AgeLine, CINAHL, EBM Reviews, MEDLINE (Ovid), SportDiscus and Web of Science) and grey literature (clinical trial registries, theses/dissertations, abstracts/conference proceedings and relevant websites). 2 team members will independently screen records (first titles and abstracts, then full text) and extract data from included records. Numerical and narrative analyses will be presented by theme (biomechanical efficacy, clinical effectiveness, cost-effectiveness, workplace safety). This scoping review responds to the information needs of healthcare decision-makers tasked with preventing fall-related injuries. This review will summarise evidence about compliant flooring as a potential intervention for preventing fall-related injuries in older adults and identify gaps in evidence and new avenues for research. Results will be especially useful in long-term care, but also applicable in acute care, assisted living and home care. We will disseminate the review's findings via open-access publications, conference presentations, a webinar, a Stakeholder Symposium and a Knowledge-to-Action Report.

  19. Enlargement of the supraglottal cavity and its relation to stop consonant voicing.

    Westbury, J R

    1983-04-01

    Measurements were made of saggital plane movements of the larynx, soft palate, and portions of the tongue, from a high-speed cinefluorographic film of utterances produced by one adult male speaker of American English. These measures were then used to approximate the temporal variations in supraglottal cavity volume during the closures of voiced and voiceless stop consonants. All data were subsequently related to a synchronous acoustic recording of the utterances. Instances of /p,t,k/ were always accompanied by silent closures, and sometimes accompanied by decreases in supraglottal volume. In contrast, instances of /b,d,g/ were always accompanied both by significant intervals of vocal fold vibration during closure, and relatively large increases in supraglottal volume. However, the magnitudes of volume increments during the voiced stops, and the means by which those increments were achieved, differed considerably across place of articulation and phonetic environment. These results are discussed in the context of a well-known model of the breath-stream control mechanism, and their relevance for a general theory of speech motor control is considered.

  20. The influence of headform orientation and flooring systems on impact dynamics during simulated fall-related head impacts.

    Wright, Alexander D; Laing, Andrew C

    2012-10-01

    Novel compliant flooring systems are a promising approach for reducing fall-related injuries in seniors, as they may provide up to 50% attenuation in peak force during simulated hip impacts while eliciting only minimal influences on balance. This study aimed to determine the protective capacity of novel compliant floors during simulated 'high severity' head impacts compared to common flooring systems. A headform was impacted onto a common Commercial-Carpet at 1.5, 2.5, and 3.5 m/s in front, back, and side orientations using a mechanical drop tower. Peak impact force applied to the headform (F(max)), peak linear acceleration of the headform (g(max)) and Head Injury Criterion (HIC) were determined. For the 3.5 m/s trials, backwards-oriented impacts were associated with the highest F(max) and HIC values (pfloors (Resilient Rubber, Residential-Loop Carpet, Berber Carpet) and six novel compliant floors at each impact velocity. ANOVAs indicated that flooring type was associated with all parameters at each impact velocity (pfloors (pfloors can substantially reduce the forces and accelerations applied to a headform compared to common floors including carpet and resilient rubber. In combination with reports of minimal balance impairments, these findings support the promise of novel compliant floors as a biomechanically effective strategy for reducing fall-related injuries including traumatic brain injuries and skull fractures.

    2018-01-01

    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

  3. Perceived floor slipperiness and floor roughness in a gait experiment.

    Yu, Ruifeng; Li, Kai Way

    2015-01-01

    Slips and falls contribute to occupational injuries and fatalities globally. Both floor slipperiness and floor roughness affect the occurrence of slipping and falling. Investigations on fall-related phenomena are important for the safety and health of workers. The purposes of this study were to: compare the perceived floor slipperiness before and after walking on the floor; compare the perceived floor slipperiness with and without shoes for males and females; discuss the perceived floor roughness based on barefoot walking; and establish regression models to describe the relationship between perceived floor slipperiness and actual friction of the floors. Male and female subjects walked on 3 m walkways with or without shoes. The perceived floor slipperiness ratings both before and after their walk were collected. The perceived floor slipperiness both before and after walking were significantly affected by both floor and surface conditions. Gender, floor, surface, and footwear conditions were all significant factors affecting the adjustment of perceived floor slipperiness. The subjects made more adjustment on perceived floor slipperiness rating when they had shoes on than when they were barefooted. Regression models were established to describe the relationship between perceived floor slipperiness and floor coefficient of friction. These models may be used to estimate perceived floor slipperiness, or in reverse, the coefficient of friction of the floor, so as to prevent slipping and falling in workplaces.

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

    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.

  6. Compliant flooring to prevent fall-related injuries in older adults: A scoping review of biomechanical efficacy, clinical effectiveness, cost-effectiveness, and workplace safety.

    Lachance, Chantelle C; Jurkowski, Michal P; Dymarz, Ania C; Robinovitch, Stephen N; Feldman, Fabio; Laing, Andrew C; Mackey, Dawn C

    2017-01-01

    Compliant flooring, broadly defined as flooring systems or floor coverings with some level of shock absorbency, may reduce the incidence and severity of fall-related injuries in older adults; however, a lack of synthesized evidence may be limiting widespread uptake. Informed by the Arksey and O'Malley framework and guided by a Research Advisory Panel of knowledge users, we conducted a scoping review to answer: what is presented about the biomechanical efficacy, clinical effectiveness, cost-effectiveness, and workplace safety associated with compliant flooring systems that aim to prevent fall-related injuries in healthcare settings? We searched academic and grey literature databases. Any record that discussed a compliant flooring system and at least one of biomechanical efficacy, clinical effectiveness, cost-effectiveness, or workplace safety was eligible for inclusion. Two independent reviewers screened and abstracted records, charted data, and summarized results. After screening 3611 titles and abstracts and 166 full-text articles, we included 84 records plus 56 companion (supplementary) reports. Biomechanical efficacy records (n = 50) demonstrate compliant flooring can reduce fall-related impact forces with minimal effects on standing and walking balance. Clinical effectiveness records (n = 20) suggest that compliant flooring may reduce injuries, but may increase risk for falls. Preliminary evidence suggests that compliant flooring may be a cost-effective strategy (n = 12), but may also result in increased physical demands for healthcare workers (n = 17). In summary, compliant flooring is a promising strategy for preventing fall-related injuries from a biomechanical perspective. Additional research is warranted to confirm whether compliant flooring (i) prevents fall-related injuries in real-world settings, (ii) is a cost-effective intervention strategy, and (iii) can be installed without negatively impacting workplace safety. Avenues for future research are

  7. Correlation study regarding the pelvic floor hypotonia in relation to labour, age and number of births

    Doriana Ioana CIOBANU

    2017-03-01

    Full Text Available Background. During pregnancy, there is an increased pressure on pelvic floor. During labour and delivery the pelvic floor is stretched and can be damaged, leading to urine leakage, mostly during laughing, sneezing, coughing, running. This condition is called urinary incontinence. Aim. This paperwork aims to emphasize if there is a significant correlation between labor parameters, age, number of deliveries and the presence of pelvic floor hypotonia and urinary incontinence in women, after delivery. Material and method. Study was made on 24 women in the first days after delivery, ages between 21- 42 years old. 66,7% are primiparous, 33,3% are multiparous. As the assessment tools were used: stop urine test, number of perineal muscle contractions, questionnaire regarding the presence of urge urinary incontinence. Results. From the total number of subjects, 33.3% have stress incontinence and 29.2% have urge incontinence. There is a significant correlation between the presence of urinary incontinence and living environment [p = 0,014, (df. = 1], smoking [p = 0,014], the onset of labor [p = 0,014], administration of antispaspasmodic medication in labor [p = 0,010], administration of antialgic medication [p = 0,014] and the duration of delivery period [p = 0,028]. Conclusions. From the 24 subjects, 62,5% of them have urinary incontinence after labor and delivery. From these, 33.3% have stress incontinence, and 29.2% have urge incontinence. After labor and delivery more affected are fast fibers of perineal muscles, responsible withholding the urine during coughing, sneezing, lifting objects, going upstairs, as well as withholding the urine in case of overflow bladder. After labor and delivery, most women have hypotonia of perineal muscles.

    Immunoglobulin G4-related disease (IgG4-RD) is a recently recognized disease entity characterized by high-serum IgG4 concentration and IgG4-producing plasma cell production with fibrotic or sclerotic changes in affected organs. We aimed to clarify the roles of Epstein-Barr virus (EBV) in patients with IgG4-RDs. A retrospective clinical study at the Yamagata University School of Medicine, Yamagata, Japan. The patient group consisted of four males and four females with an average age of 62 years (range: 48-73). Expression of IgG4, latent member protein 1, EBV nuclear antigens-2, and EBV-encoded RNA in affected salivary glands from patients with IgG4-RD was examined by using immunohistochemistry and in situ hybridization. The copy number of EBV DNA in the salivary glands was also investigated by real-time polymerase chain reaction. All patients had hard masses in the salivary or lacrimal glands, or both, bilaterally. Serum concentrations of IgG4 were elevated in all cases (mean 589.1, range 129-1750), and IgG4-positive plasmacytes were observed in the involved salivary glands. Four patients developed potentially life-threatening systemic involvement after initial salivary gland swelling. EBV-associated molecules (EBNA and EBER) were overexpressed in the affected salivary glands. The copy number of EBV DNA was significantly higher in patients with potentially life-threatening systemic involvement than in patients without systemic involvement (P < 0.05). These results suggest that the copy number of EBV DNA could be useful as diagnostic findings in IgG4-RD to predict potentially life-threatening systemic involvement. 4. © 2015 The American Laryngological, Rhinological and Otological Society, Inc.

  13. Daoy medulloblastoma cells that express CD133 are radioresistant relative to CD133- cells, and the CD133+ sector is enlarged by hypoxia

    Blazek, Ed R.; Foutch, Jennifer L.; Maki, Guitta

    2007-01-01

    Purpose: Primary medulloblastoma and glioblastoma multiforme tumor cells that express the surface marker CD133 are believed to be enriched for brain tumor stem cells because of their unique ability to initiate or reconstitute tumors in immunodeficient mice. This study sought to characterize the radiobiological properties and marker expression changes of CD133+ vs. CD133- cells of an established medulloblastoma cell line. Methods and Materials: Daoy and D283 Med cell lines were stained with fluorescently labeled anti-CD133 antibody and sorted into CD133+ and CD133- populations. The effect of oxygen (2% vs. 20%) on CD133 expression was measured. Both populations were analyzed for marker stability, cell cycle distribution, and radiosensitivity. Results: CD133+ Daoy cells restored nearly native CD133+ and CD133- populations within 18 days, whereas CD133- cells remained overwhelmingly CD133-. Culturing Daoy cells in 2% oxygen rather than the standard 20% oxygen increased their CD133 expression 1.6-fold. CD133+ Daoy cells were radioresistant via the β-parameter of the linear-quadratic model relative to CD133- Daoy cells, although their α-parameters and cell cycle distributions were identical. Conclusions: Restoration of the original CD133+ and CD133- populations from CD133+ Daoy cells in serum is further evidence that CD133+ cells are functionally distinct from CD133- cells. The radioresistance of CD133+ compared with CD133- Daoy cells is consistent with better repair of sublethal damage. Enlargement of the CD133+ sector is a new feature of the hypoxic response

  14. Use of dynamic 3-dimensional transvaginal and transrectal ultrasonography to assess posterior pelvic floor dysfunction related to obstructed defecation.

    2014-02-01

    New ultrasound techniques may complement current diagnostic tools, and combined techniques may help to overcome the limitations of individual techniques for the diagnosis of anorectal dysfunction. A high degree of agreement has been demonstrated between echodefecography (dynamic 3-dimensional anorectal ultrasonography) and conventional defecography. Our aim was to evaluate the ability of a combined approach consisting of dynamic 3-dimensional transvaginal and transrectal ultrasonography by using a 3-dimensional biplane endoprobe to assess posterior pelvic floor dysfunctions related to obstructed defecation syndrome in comparison with echodefecography. This was a prospective, observational cohort study conducted at a tertiary-care hospital. Consecutive female patients with symptoms of obstructed defecation were eligible. Each patient underwent assessment of posterior pelvic floor dysfunctions with a combination of dynamic 3-dimensional transvaginal and transrectal ultrasonography by using a biplane transducer and with echodefecography. Kappa (κ) was calculated as an index of agreement between the techniques. Diagnostic accuracy (sensitivity, specificity, and positive and negative predictive values) of the combined technique in detection of posterior dysfunctions was assessed with echodefecography as the standard for comparison. A total of 33 women were evaluated. Substantial agreement was observed regarding normal relaxation and anismus. In detecting the absence or presence of rectocele, the 2 methods agreed in all cases. Near-perfect agreement was found for rectocele grade I, grade II, and grade III. Perfect agreement was found for entero/sigmoidocele, with near-perfect agreement for rectal intussusception. Using echodefecography as the standard for comparison, we found high diagnostic accuracy of transvaginal and transrectal ultrasonography in the detection of posterior dysfunctions. This combined technique should be compared with other dynamic techniques and

    Garcia, M.; Gonzalez, J.; Martinez, A.; Garcia, M.A.; Relea, A.; Narajo, G.

    1996-01-01

    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

  18. Age-related changes and sex differences in postural control adaptability in children during periodic floor oscillation with eyes closed.

    Fujiwara, Katsuo; Kiyota, Takeo; Mammadova, Aida; Yaguchi, Chie

    2011-01-01

    We investigated age-related changes and sex differences in adaptability of anticipatory postural control in children. Subjects comprised 449 children (4-12 years old) and 109 young adults (18-29 years old). Subjects stood with eyes closed on a force-platform fixed to a floor oscillator. We conducted five trials of 1-minute oscillation (0.5 Hz frequency, 2.5 cm amplitude) in the anteroposterior direction. Postural steadiness was quantified as the mean speed of the center of pressure in the anteroposterior direction (CoPy). In young adults, CoPy speed decreased rapidly until the third trial for both sexes. Adaptability was evaluated by changes in steadiness. The adaptability of children was categorized as "good," "moderate," and "poor," compared with a standard variation of the mean CoPy speed regression line between the first and fifth trials in young adults. Results were as follows: (1) anticipatory postural control adaptability starts to develop from age 6 in boys and 5 in girls, and greatly improves at age 7-8 in boys and 6 in girls; (2) the adaptability of children at age 11-12 (74% of boys and 63% of girls were categorized as "good") has not yet reached the same level as for young adults; (3) the adaptability at age 11-12 for girls is temporarily disturbed due to early puberty.

    Radiotherapy is a cancer treatment that uses high-energy X-rays or other types of ionizing radiation to try to kill the cancer cells in various organs/tissues. PubMed is a database used as a tool in various publications. The aim of this work was to evaluate, in the PubMed, the number of publications (NP) in radiotherapy and cancer in various organs related to the pelvic floor as well as brachytherapy. The searches were performed (August 2008) in the PubMed (http://www.pubmed.com) using the words: radiotherapy (RT) or cancer (CA), RT and CA, RT and CA and prostate, RT and CA and testis, RT and CA and breast, RT and CA and kidneys, RT and CA and vulva, RT and CA and vagina, RT and CA and penis, RT and CA and uterus, RT and CA and ovary, RT and CA and bladder, and RT and CA and urethra. A search using brachytherapy was also performed. The NP in each subject was determined and was 2178635 to CA and about 9% of them are related with RT. The NP in RT and CA and breast or prostate is bigger than for the other organs, whereas brachytherapy is mainly cited in the studies about CA of prostate, bladder and breast. In conclusion, our findings demonstrate the importance of radiation therapy studies in the cancer of several organs. This information is crucial in understanding the field and demonstrates areas of significant progress or existing gaps of research in radiotherapy treatment of various cancers of the pelvis. Furthermore, it could significantly aid the interprofessional team in the determination of actions related to the treatment of patients that are undertaking radiotherapy, due to the possible complications of this modality of treatment.

  4. EU ENLARGEMENT AT A CROSSROADS

    Andreea Cătălina Paul

    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.

    1999-01-01

    The amount of Linear Alkylbenzenesulfonates (LAS) in the particle fraction of floor dust sampled from 7 selected public buildings varied between 34 and 1500 microgram per gram dust, while the contents of the fibre fractions generally were higher with up to 3500 microgram LAS/g dust. The use...... of a cleaning agent with LAS resulted in an increase of the amount of LAS in the floor dust after floor wash relative to just before floor wash. However, the most important source of LAS in the indoor floor dust appears to be residues of detergent in clothing. Thus, a newly washed shirt contained 2960 microgram...

    2017-11-01

    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

  7. Price floors for emissions trading

    Wood, Peter John; Jotzo, Frank

    2011-01-01

    Price floors in greenhouse gas emissions trading schemes can guarantee minimum abatement efforts if prices are lower than expected, and they can help manage cost uncertainty, possibly as complements to price ceilings. Provisions for price floors are found in several recent legislative proposals for emissions trading. Implementation however has potential pitfalls. Possible mechanisms are government commitments to buy back permits, a reserve price at auction, or an extra fee or tax on acquittal of emissions permits. Our analysis of these alternatives shows that the fee approach has budgetary advantages and is more compatible with international permit trading than the alternatives. It can also be used to implement more general hybrid approaches to emissions pricing. - Research highlights: → Price floors for emissions trading schemes guarantee a minimum carbon price. → Price floors mean that emissions can be less than specified by the ETS cap. → We examine how price floors can relate to different policy objectives. → We compare different mechanisms for implementing a price floor. → We find that a mechanism where there is an extra tax or fee has advantages.

  9. Seismic and dynamic qualification of safety-related electrical and mechanical equipment in operating nuclear power plants: development of a method to generate generic floor-response spectra

    Curreri, J.; Costantino, C.; Subudhi, M.; Reich, M.

    1983-09-01

    Generic floor response spectra were developed for use in the qualification of electrical and mechanical equipment in operating nuclear power plants. The characteristics of 1000 floor response spectra were studied to determine the generic spectra. The procedure developed uses as much or as little information that currently exists at the plant relating to the question of equipment qualification. The general approach was to study the effects on the dynamic characteristics of each of the elements in the chain of events that goes between the loads and the responses. This includes the loads, the soils and the structures. A free-field earthquake response spectra was used to generate horizontal earthquake time histories. The excitation was applied through the soil and into the various structures to produce responses in equipment. An entire range of soil conditions was used with each structure. Actual PWR and BWR - Mark I structural models were used. For each model, the stiffness properties were varied, with the same mass, so as to extend the fundamental base structure natural frequency from 2 cps to 36 cps. The natural frequencies of the structures were varied to obtain maximum response conditions. The actual properties were first used to locate the natural frequencies. The stiffness properties were than varied, with the same mass, to extend the range of the fundamental base structure natural frequency. The intention was to have the coupled structural material frequencies in the vicinity of the peak amplitude frequency content of the excitation spectrum. Particular attention was therefore given to the frequency band between 2 Hz and 4 Hz. A horizontal generic floor response spectra is proposed for the top level of a generic structure. Reduction factors are applied to the peak acceleration for equipment at lower levels

    Full Text Available Different trailer flooring materials, including wood-based, aluminum, steel, and synthetic plastic floors, were evaluated in accordance with their durability and sustainability to our natural environment. Wood-based trailer flooring is an eco-friendly product. It is the most sustainable trailer flooring material compared with fossil fuel-intensive steel, aluminum, and plastics. It is renewable and recyclable. Oak, hard maple, and apitong are strong and durable hardwood species that are currently extensively used for trailer flooring. For manufacture, wood-based flooring is higher in energy efficiency and lower in carbon emission than steel, aluminum and plastics. Moreover, wood per se is a natural product that sequesters carbon. Accordingly, using more wood-based trailer flooring is effective to reduce global warming.

  14. Patients with Parkinson's disease display a dopamine therapy related negative bias and an enlarged range in emotional responses to facial emotional stimuli.

    Lundqvist, Daniel; Svärd, Joakim; Michelgård Palmquist, Åsa; Fischer, Håkan; Svenningsson, Per

    2017-09-01

    The literature on emotional processing in Parkinson's disease (PD) patients shows mixed results. This may be because of various methodological and/or patient-related differences, such as failing to adjust for cognitive functioning, depression, and/or mood. In the current study, we tested PD patients and healthy controls (HCs) using emotional stimuli across a variety of tasks, including visual search, short-term memory (STM), categorical perception, and emotional stimulus rating. The PD and HC groups were matched on cognitive ability, depression, and mood. We also explored possible relationships between task results and antiparkinsonian treatment effects, as measured by levodopa equivalent dosages (LED), in the PD group. The results show that PD patients use a larger emotional range compared with HCs when reporting their impression of emotional faces on rated emotional valence, arousal, and potency. The results also show that dopaminergic therapy was correlated with stimulus rating results such that PD patients with higher LED scores rated negative faces as less arousing, less negative, and less powerful. Finally, results also show that PD patients display a general slowing effect in the visual search tasks compared with HCs, indicating overall slowed responses. There were no group differences observed in the STM or categorical perception tasks. Our results indicate a relationship between emotional responses, PD, and dopaminergic therapy, in which PD per se is associated with stronger emotional responses, whereas LED levels are negatively correlated with the strength of emotional responses.

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

    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.

  16. The Fungal Defensin Family Enlarged

    2014-08-01

    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.

  4. Solving decontaminable flooring problems

    Anon.

    1989-01-01

    Pennsylvania Power and Light wanted to cover deteriorating concrete in unit 2 of its Susquehanna BWR with a smooth, durable, decontaminable coating. Traditionally, floors in the plant had been coated with epoxy paint, but many of these floors suffered delamination, and failed in three to five years. Painting with epoxy would also interrupt operations for as much as three days while the floor dried, yet critical instruments in some areas had to be monitored at least once per shift. In addition, conventional floor surface preparation produced dust and vibration around sensitive equipment. The solution was a dustless scabbling system for surface preparation, followed by the installation of a high-strength acrylic industrial floor known as Silakal. The work was carried out by Pentek. Silikal bonds to the underlying concrete, so that delamination of the floor will not occur even under severe traffic conditions. Another advantage of this type of flooring is that it cures in one hour, so floor resurfacing has only minimal impact on plant operations. (author)

  8. Container floor at high temperatures

    Reutler, H.; Klapperich, H.J.; Mueller-Frank, U.

    1978-01-01

    The invention describes a floor for container which is stressed at high, changing temperatures and is intended for use in gas-cooled nuclear reactors. Due to the downward cooling gas flow in these types of reactor, the reactor floor is subjected to considerable dimensional changes during switching on and off. In the heating stage, the whole graphite structure of the reactor core and floor expands. In order to avoid arising constraining forces, sufficiently large expansion spaces must be allowed for furthermore restoring forces must be present to close the gaps again in the cooling phase. These restoring forces must be permanently present to prevent loosening of the core cuits amongst one another and thus uncontrollable relative movement. Spring elements are not suitable due to fast fatigue as a result of high temperatures and radiation exposure. It is suggested to have the floor elements supported on rollers whose rolling planes are downwards inclined to a fixed point for support. The construction is described in detail by means of drawings.

    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.

  14. Enlarged facial pores: an update on treatments.

    Dong, Joanna; Lanoue, Julien; Goldenberg, Gary

    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.

    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)

    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.

    MGS MOC Release No. MOC2-357, 11 May 2003This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) picture shows a pattern of polygons on the floor of a northern plains impact crater. These landforms are common on crater floors at high latitudes on Mars. Similar polygons occur in the arctic and antarctic regions of Earth, where they indicate the presence and freeze-thaw cycling of ground ice. Whether the polygons on Mars also indicate water ice in the ground is uncertain. The image is located in a crater at 64.8oN, 292.7oW. Sunlight illuminates the scene from the lower left.

  2. Decontamination of polyvinylchloride- and rubber type flooring

    Kunze, S.

    1975-01-01

    These types, fabricated by mixing of the basic components, showed no relation between content of fillers and decontamination results. Decontamination results are partly poorer, if the flooring contains a high concentration of the filler, especially if the latter consists mainly of hydrophilic materials. The coloring of the floorings seems to have no influence on the decontamination but floorings with clearly separated patterns can not be recommended for nuclear facilities. Fabricated by chemical reactions between polymeres, vulcanization materials and fillers, the decontamination results depend definitely from the proper choice of the filler. Flooring types, containing lampblack, graphite, kaoline, barium sulfate and titanium oxide are easy to decontamine. Again, increasing contents of hydrophilic filler cause a fall off in the decontamination results. (orig.) [de

    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.

  6. Liver enlargement demonstrated by scintigraphy in rheumatoid arthritis

    Tiger, L.H.; Gordon, M.H.; Ehrlich, G.E.; Shapiro, B.

    1976-03-01

    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.

  11. Chronic pelvic floor dysfunction.

    Hartmann, Dee; Sarton, Julie

    2014-10-01

    The successful treatment of women with vestibulodynia and its associated chronic pelvic floor dysfunctions requires interventions that address a broad field of possible pain contributors. Pelvic floor muscle hypertonicity was implicated in the mid-1990s as a trigger of major chronic vulvar pain. Painful bladder syndrome, irritable bowel syndrome, fibromyalgia, and temporomandibular jaw disorder are known common comorbidities that can cause a host of associated muscular, visceral, bony, and fascial dysfunctions. It appears that normalizing all of those disorders plays a pivotal role in reducing complaints of chronic vulvar pain and sexual dysfunction. Though the studies have yet to prove a specific protocol, physical therapists trained in pelvic dysfunction are reporting success with restoring tissue normalcy and reducing vulvar and sexual pain. A review of pelvic anatomy and common findings are presented along with suggested physical therapy management. Copyright © 2014 Elsevier Ltd. All rights reserved.

  12. Modular Flooring System

    Thate, Robert

    2012-01-01

    The modular flooring system (MFS) was developed to provide a portable, modular, durable carpeting solution for NASA fs Robotics Alliance Project fs (RAP) outreach efforts. It was also designed to improve and replace a modular flooring system that was too heavy for safe use and transportation. The MFS was developed for use as the flooring for various robotics competitions that RAP utilizes to meet its mission goals. One of these competitions, the FIRST Robotics Competition (FRC), currently uses two massive rolls of broadloom carpet for the foundation of the arena in which the robots are contained during the competition. The area of the arena is approximately 30 by 72 ft (approximately 9 by 22 m). This carpet is very cumbersome and requires large-capacity vehicles, and handling equipment and personnel to transport and deploy. The broadloom carpet sustains severe abuse from the robots during a regular three-day competition, and as a result, the carpet is not used again for competition. Similarly, broadloom carpets used for trade shows at convention centers around the world are typically discarded after only one use. This innovation provides a green solution to this wasteful practice. Each of the flooring modules in the previous system weighed 44 lb (.20 kg). The improvements in the overall design of the system reduce the weight of each module by approximately 22 lb (.10 kg) (50 %), and utilize an improved "module-to-module" connection method that is superior to the previous system. The MFS comprises 4-by-4-ft (.1.2-by- 1.2-m) carpet module assemblies that utilize commercially available carpet tiles that are bonded to a lightweight substrate. The substrate surface opposite from the carpeted surface has a module-to-module connecting interface that allows for the modules to be connected, one to the other, as the modules are constructed. This connection is hidden underneath the modules, creating a smooth, co-planar flooring surface. The modules are stacked and strapped

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

    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.

  14. THE IMPACT OF EU ENLARGEMENT ON THE RUSSIAN FEDERATION

    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.

    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.)

  17. Aortic Root Enlargement or Sutureless Valve Implantation?

    Nikolaos G. Baikoussis

    2016-11-01

    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.

    Penis lengthening pills, stretch apparatus, vacuum pumps, silicone injections, and lengthening and thickening operations are available for men who worry about their penis size. Surgery is thus far the only proven scientific method for penile enlargement. In this article, we consider patient selection, outcome evaluation, and techniques applied. In our view, sexological counseling and detailed explanation of risks and complications are mandatory before any operative intervention.

  19. THE CRUCIAL THEMES OF EU ENLARGEMENT

    Jacques Pelkmans

    2001-12-01

    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.

  20. Ventricular enlargement in patients with affective disorders

    Murashita, Jun; Kato, Tadafumi; Shioiri, Toshiki; Hamakawa, Inubushi, Toshiro; Hiroshi; Takahashi, Saburo

    1994-01-01

    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.)

  1. Imaging of the posterior pelvic floor

    Stoker, Jaap; Bartram, Clive I.; Halligan, Steve

    2002-01-01

    Disorders of the posterior pelvic floor are relatively common. The role of imaging in this field is increasing, especially in constipation, prolapse and anal incontinence, and currently imaging is an integral part of the investigation of these pelvic floor disorders. Evacuation proctography provides both structural and functional information for rectal voiding and prolapse. Dynamic MRI may be a valuable alternative as the pelvic floor muscles are visualised, and it is currently under evaluation. Endoluminal imaging is important in the management of anal incontinence. Both endosonography and endoanal MRI can be used for detection of anal sphincter defects. Endoanal MRI has the advantage of simultaneously evaluating external sphincter atrophy, which is an important predictive factor for the outcome of sphincter repair. Many aspects of constipation and prolapse remain incompletely understood and treatment is partly empirical; however, imaging has a central role in management to place patients into treatment-defined groups.

  3. Fine-scale relief related to late holocene channel shifting within the floor of the upper Redondo Fan, offshore Southern California

    Normark, W.R.; Paull, C.K.; Caress, D.W.; Ussler, W.; Sliter, R.

    2009-01-01

    Erosional and depositional bedforms have been imaged at outcrop scale in the upper Redondo Fan, in the San Pedro Basin of offshore Southern California in ???600 m water depths, using an Autonomous Underwater Vehicle developed by the Monterey Bay Aquarium Research Institute. The Autonomous Underwater Vehicle is equipped with multibeam and chirp sub-bottom sonars. Sampling and photographic images using the Monterey Bay Aquarium Research Institute Remotely Operated Vehicle Tiburon provide groundtruth for the Autonomous Underwater Vehicle survey. The 0??3 m vertical and 1??5 m lateral bathymetric resolution and 0??1 m sub-bottom profile resolution provide unprecedented detail of bedform morphology and structure. Multiple channels within the Redondo Fan have been active at different times during the Late Holocene (0 to 3000 yr bp). The currently active channel extending from Redondo Canyon makes an abrupt 90?? turn at the canyon mouth before resuming a south-easterly course along the east side of the Redondo Fan. This channel is floored by sand and characterized by small steps generally <1 m in relief, spaced 10 to 80 m in the down-channel direction. A broader channel complex lies along the western side of the fan valley that was last active more than 850 years ago. Two distinct trains of large scours, with widths ranging from tens to a few hundred metres and depths of 20 m, occur on the floor of the western channel complex, which has a thin mud drape. If observed in cross-section only, these large scours would probably be misidentified as the thalweg of an active channel. ?? 2009 The Authors.

  5. Sea floor magnetic observatory

    Korepanov, V.; Prystai, A.; Vallianatos, F.; Makris, J.

    2003-04-01

    The electromagnetic precursors of seismic hazards are widely accepted as strong evidence of the approaching earthquake or volcano eruption. The monitoring of these precursors are of main interest in densely populated areas, what creates serious problems to extract them at the strong industrial noise background. An interesting possibility to improve signal-to-noise ratio gives the installation of the observation points in the shelf zones near the possible earthquake places, what is fairly possible in most seismically active areas in Europe, e. g. in Greece and Italy. The serious restriction for this is the cost of the underwater instrumentation. To realize such experiments it requires the unification of efforts of several countries (e. g., GEOSTAR) or of the funds of some great companies (e. g., SIO magnetotelluric instrument). The progress in electronic components development as well as the appearance of inexpensive watertight glass spheres made it possible to decrease drastically the price of recently developed sea floor magnetic stations. The autonomous vector magnetometer LEMI-301 for sea bed application is described in the report. It is produced on the base of three-component flux-gate sensor. Non-magnetic housing and minimal magnetism of electronic components enable the instrument to be implemented as a monoblock construction where the electronic unit is placed close to the sensor. Automatic circuit provides convenient compensation of the initial field offset and readings of full value (6 digits) of the measured field. Timing by internal clock provides high accuracy synchronization of data. The internal flash memory assures long-term autonomous data storage. The system also has two-axes tilt measurement system. The methodological questions of magnetometer operation at sea bed were studied in order to avoid two types of errors appearing at such experimental cases. First is sea waving influence and second one magnetometer orientation at its random positioning on

  6. Branding on the Shop Floor

    Szilvia Gyimóthy

    2010-09-01

    Full Text Available Service branding is a particular form of emotional management, where employees are regarded as adaptable media, who can be trained to convey corporate values while interacting with customers. This paper examines the identity work of butchers during the brand revitalisation campaign of Kvickly, a Danish supermarket chain. During the implementation of the “Best Butcher in Town”-project, Kvickly’s shop floor becomes an engineered servicescape where the norms of good salesmanship must be performed. By documenting the disloyal behaviour of butchers, we demonstrate that the affective commitment towards corporate brand values is closely related with self-enactment opportunities of occupational communities. Total service-orientation threatens butchers’ perception of autonomy and may therefore result in the emergence of resistant sub-cultures.

    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

    Storing heat in floors by using economical night-time electricity does not increase the specific consumption of heating. According to studies done by IVO, the optimum housing comfort is achieved if the room is heated mainly by means of floor heating that is evened out by window or ceiling heating, or by a combination of all three forms of heating.

  10. Hearing loss and enlarged internal auditory canal in children.

    Santos, Saturnino; Domínguez, M Jesús; Cervera, Javier; Suárez, Alicia; Bueno, Antonio; Bartolomé, Margarita; López, Rafael

    2014-01-01

    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.

  11. Indoor radon seasonal variability at different floors of buildings

    De Francesco, S.; Tommasone, F. Pascale; Cuoco, E.; Tedesco, D.

    2010-01-01

    Indoor radon concentrations have been measured with the α track etch integrated method in public buildings in the town of Pietramelara, north-western Campania, Southern Italy. In particular, our measurements were part of an environmental monitoring program originally aimed at assessing the range of seasonal fluctuations in indoor radon concentrations, at various floors of the studied buildings. However, subsequent analysis of the data and its comparison with the meteorological data recorded in the same period has shown an unexpected pattern at the different floors. In this report we present data suggesting that, besides the well-known medium and longterm periodicity, there could also be a differentiation in major meteorological controlling factors at the different floors of the buildings, a fact that does not appear to have been reported previously. While the lower floors proved to be markedly affected by rainfall, for the upper floors, instead, a different behaviour has been detected, which could possibly be related to global solar radiation.

  12. Biological findings from the PheWAS catalog: focus on connective tissue-related disorders (pelvic floor dysfunction, abdominal hernia, varicose veins and hemorrhoids).

    Salnikova, Lyubov E; Khadzhieva, Maryam B; Kolobkov, Dmitry S

    2016-07-01

    Pelvic floor dysfunction, specifically genital prolapse (GP) and stress urinary inconsistency (SUI) presumably co-occur with other connective tissue disorders such as hernia, hemorrhoids, and varicose veins. Observations on non-random coexistence of these disorders have never been summarized in a meta-analysis. The performed meta-analysis demonstrated that varicose veins and hernia are associated with GP. Disease connections on the molecular level may be partially based on shared genetic susceptibility. A unique opportunity to estimate shared genetic susceptibility to disorders is provided by a PheWAS (phenome-wide association study) designed to utilize GWAS data concurrently to many phenotypes. We searched the PheWAS Catalog, which includes the results of the PheWAS study with P value hemorrhoids. We found pronounced signals for the associations of the SLC2A9 gene with SUI (P = 6.0e-05) and the MYH9 gene with varicose veins of lower extremity (P = 0.0001) and hemorrhoids (P = 0.0007). The comparison of the PheWAS Catalog and the NHGRI Catalog data revealed enrichment of genes associated with bone mineral density in GP and with activated partial thromboplastin time in varicose veins of lower extremity. In cross-phenotype associations, genes responsible for peripheral nerve functions seem to predominate. This study not only established novel biologically plausible associations that may warrant further studies but also exemplified an effective use of the PheWAS Catalog data.

  15. EU Enlargement between Economic and Political Criteria

    Romeo-Victor Ionescu

    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.

  16. An enlarged superfluid model of atomic nucleus

    Dumitrescu, O.; Horoi, M.

    1989-01-01

    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

  18. Subsidy policy and the enlargement of choice

    Srinivasan, Sunderasan

    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.

    White, R D

    2007-12-01

    Floors are a major element of newborn intensive care unit (NICU) construction. They provide visual cues, sound control, and with certain materials, some degree of physical comfort for workers. Flooring materials may entail a significant cost for installation and upkeep and can have substantial ecological impact, both in the choice of the flooring itself, as well as the substances used to clean it. In this article the important aspects to consider for each factor are explored and recommendations are offered for appropriate choices in various NICU areas.

    Physical therapists are uniquely qualified to treat pelvic floor dysfunction with conservative management techniques. Techniques associated with incontinence and support functions of the pelvic floor include bladder training and pelvic floor rehabilitation: pelvic floor exercises, biofeedback therapy, and pelvic floor electrical stimulation. Pain associated with mechanical pelvic floor dysfunction can be treated by physical therapists utilizing various manual techniques and modalities. Research documents that conservative management is effective in treating many conditions associated with pelvic floor dysfunction. Research should be conducted to determine if addressing diastasis recti and contracture of the pelvic floor musculature should be a component of the standard physical therapy protocol.

  4. Disappearance of enlarged nuchal translucency before 14 weeks' gestation: relationship with chromosomal abnormalities and pregnancy outcome.

    Müller, M A; Pajkrt, E; Bleker, O P; Bonsel, G J; Bilardo, C M

    2004-08-01

    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

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

    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

  6. 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)

  7. Acrolein Induces Endoplasmic Reticulum Stress and Causes Airspace Enlargement

    Hanaoka, Masayuki; Natarajan, Ramesh; Kraskauskas, Donatas; Voelkel, Norbert F.

    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

On the contrary to understand completely nature and function of the pelvic floor it is necessary to study it in the most unitary view and in the most global aspect, considering embriology, philogenesy, anthropologic development and its multiple activities others than urological, gynaecological and intestinal ones. Recent acquirements succeeded in clarifying many aspects of pelvic floor activity, whose musculature has been investigated through electromyography, sonography, magnetic resonance, histology, histochemistry, molecular research. Utilizing recent research concerning not only urinary and gynecologic aspects but also those regarding statics and dynamics of pelvis and its floor, it is now possible to study this important body part as a unit; that means to consider it in the whole body economy to which maintaining upright position, walking and behavior or physical conduct do not share less than urinary, genital, and intestinal functions. It is today possible to consider the pelvic floor as a musclefascial unit with synergic and antagonistic activity of muscular bundles, among them more or less interlaced, with multiple functions and not only the function of pelvic cup closure.

    2012-09-01

    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.

    Dreimanis, A.

    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)

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

    Yuka Muraoka

    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.

    2004-01-01

    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

  15. Conduit enlargement in an eogenetic karst aquifer

    Moore, Paul J.; Martin, Jonathan B.; Screaton, Elizabeth J.; Neuhoff, Philip S.

    2010-11-01

    SummaryMost concepts of conduit development have focused on telogenetic karst aquifers, where low matrix permeability focuses flow and dissolution along joints, fractures, and bedding planes. However, conduits also exist in eogenetic karst aquifers, despite high matrix permeability which accounts for a significant component of flow. This study investigates dissolution within a 6-km long conduit system in the eogenetic Upper Floridan aquifer of north-central Florida that begins with a continuous source of allogenic recharge at the Santa Fe River Sink and discharges from a first-magnitude spring at the Santa Fe River Rise. Three sources of water to the conduit include the allogenic recharge, diffuse recharge through epikarst, and mineralized water upwelling from depth. Results of sampling and inverse modeling using PHREEQC suggest that dissolution within the conduit is episodic, occurring only during 30% of 16 sampling times between March 2003 and April 2007. During low flow conditions, carbonate saturated water flows from the matrix to the conduit, restricting contact between undersaturated allogenic water with the conduit wall. When gradients reverse during high flow conditions, undersaturated allogenic recharge enters the matrix. During these limited periods, estimates of dissolution within the conduit suggest wall retreat averages about 4 × 10 -6 m/day, in agreement with upper estimates of maximum wall retreat for telogenetic karst. Because dissolution is episodic, time-averaged dissolution rates in the sink-rise system results in a wall retreat rate of about 7 × 10 -7 m/day, which is at the lower end of wall retreat for telogenetic karst. Because of the high permeability matrix, conduits in eogenetic karst thus enlarge not just at the walls of fractures or pre-existing conduits such as those in telogenetic karst, but also may produce a friable halo surrounding the conduits that may be removed by additional mechanical processes. These observations stress the

    Bottom trawling is a non-selective commercial fishing technique whereby heavy nets and gear are pulled along the sea floor. The direct impact of this technique on fish populations and benthic communities has received much attention, but trawling can also modify the physical properties of seafloor sediments, water–sediment chemical exchanges and sediment fluxes. Most of the studies addressing the physical disturbances of trawl gear on the seabed have been undertaken in coastal and shelf environments, however, where the capacity of trawling to modify the seafloor morphology coexists with high-energy natural processes driving sediment erosion, transport and deposition. Here we show that on upper continental slopes, the reworking of the deep sea floor by trawling gradually modifies the shape of the submarine landscape over large spatial scales. We found that trawling-induced sediment displacement and removal from fishing grounds causes the morphology of the deep sea floor to become smoother over time, reducing its original complexity as shown by high-resolution seafloor relief maps. Our results suggest that in recent decades, following the industrialization of fishing fleets, bottom trawling has become an important driver of deep seascape evolution. Given the global dimension of this type of fishery, we anticipate that the morphology of the upper continental slope in many parts of the world’s oceans could be altered by intensive bottom trawling, producing comparable effects on the deep sea floor to those generated by agricultural ploughing on land.

    2008-01-01

    Endoscopic repair of orbital blow-out fractures could become a predictable and efficient treatment alternative to traditional methods. However, maxillary sinus endoscopy provides a complex and disorienting view of the orbital floor. To be a useful and consistent technique for providing access to the orbital floor, specific knowledge of maxillary endoscopic anatomy is required. The purpose of the study was to provide an anatomic description of the orbital floor via the endoscopic approach. Objectives include defining consistent landmarks for use in endoscopic repair of orbital floor fractures. Using 0- and 30-degree rigid endoscopes, 6 fresh cadavers (12 maxillary sinuses) were examined via a standard Caldwell-Luc approach. Computed tomographic scans, plastic molds, and digital images were used to compare observable averages within bony anatomy. Potential bony landmarks were correlated with soft-tissue anatomy in fresh specimens. The maxillary ostium, orbital floor, and lateral ethmoid air cells were visualized, and their structures were described. Observations were made in relation to the anatomy of the orbital floor and maxillary sinus, including fracture pattern and force transmission pathways. An "orbitomaxillary" sinus bony thickening was identified and described for the first time. This study provides the basis for further refinement of surgical technique and opens the door for future clinical trials using endoscopic repair.

  1. External Hand Forces Exerted by Long-Term Care Staff to Push Floor-Based Lifts: Effects of Flooring System and Resident Weight.

    Lachance, Chantelle C; Korall, Alexandra M B; Russell, Colin M; Feldman, Fabio; Robinovitch, Stephen N; Mackey, Dawn C

    2016-09-01

    The aim of this study was to investigate the effects of flooring type and resident weight on external hand forces required to push floor-based lifts in long-term care (LTC). Novel compliant flooring is designed to reduce fall-related injuries among LTC residents but may increase forces required for staff to perform pushing tasks. A motorized lift may offset the effect of flooring on push forces. Fourteen female LTC staff performed straight-line pushes with two floor-based lifts (conventional, motor driven) loaded with passengers of average and 90th-percentile resident weights over four flooring systems (concrete+vinyl, compliant+vinyl, concrete+carpet, compliant+carpet). Initial and sustained push forces were measured by a handlebar-mounted triaxial load cell and compared to participant-specific tolerance limits. Participants rated pushing difficulty. Novel compliant flooring increased initial and sustained push forces and subjective ratings compared to concrete flooring. Compared to the conventional lift, the motor-driven lift substantially reduced initial and sustained push forces and perceived difficulty of pushing for all four floors and both resident weights. Participants exerted forces above published tolerance limits only when using the conventional lift on the carpet conditions (concrete+carpet, compliant+carpet). With the motor-driven lift only, resident weight did not affect push forces. Novel compliant flooring increased linear push forces generated by LTC staff using floor-based lifts, but forces did not exceed tolerance limits when pushing over compliant+vinyl. The motor-driven lift substantially reduced push forces compared to the conventional lift. Results may help to address risk of work-related musculoskeletal injury, especially in locations with novel compliant flooring. © 2016, Human Factors and Ergonomics Society.

    A case is reported, in which the combination of high TT/sub 3/- and FT/sub 4/ plasma levels, increased TSH basal secretion and enlargement of the pituitary gland did not reflect secondary hyperthyroidism, but was cuased by clinically latent hypothyroidism, probably due to thyroid hormone antibodies. High doses of thyroid hormones lowered the TSH and prolactin basal secretion, and reduced the enlargement of the pituitary gland.

    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.

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

    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.

    2000-04-01

    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)

    2011-01-01

    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. Amygdala enlargement: Temporal lobe epilepsy subtype or nonspecific finding?

    Reyes, Anny; Thesen, Thomas; Kuzniecky, Ruben; Devinsky, Orrin; McDonald, Carrie R; Jackson, Graeme D; Vaughan, David N; Blackmon, Karen

    2017-05-01

    Amygdala enlargement (AE) is observed in patients with temporal lobe epilepsy (TLE), which has led to the suggestion that it represents a distinct TLE subtype; however, it is unclear whether AE is found at similar rates in other epilepsy syndromes or in healthy controls, which would limit its value as a marker for focal epileptogenicity. We compared rates of AE, defined quantitatively from high-resolution T1-weighted MRI, in a large multi-site sample of 136 patients with nonlesional localization related epilepsy (LRE), including TLE and extratemporal (exTLE) focal epilepsy, 34 patients with idiopathic generalized epilepsy (IGE), and 233 healthy controls (HCs). AE was found in all groups including HCs; however, the rate of AE was higher in LRE (18.4%) than in IGE (5.9%) and HCs (6.4%). Patients with unilateral LRE were further evaluated to compare rates of concordant ipsilateral AE in TLE and exTLE, with the hypothesis that rates of ipsilateral AE would be higher in TLE. Although ipsilateral AE was higher in TLE (19.4%) than exTLE (10.5%), this difference was not significant. Furthermore, among the 25 patients with unilateral LRE and AE, 13 (52%) had either bilateral AE or AE contralateral to seizure onset. Results suggest that AE, as defined with MRI volumetry, may represent an associated feature of nonlesional localization related epilepsy with limited seizure onset localization value.

  13. Reconstruction of deformities resulting from penile enlargement surgery.

    Alter, G J

    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.

    1983-01-01

    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)

    2017-01-01

    Floor-fractured craters are a class of lunar crater hypothesized to form in response to the emplacement of a shallow magmatic intrusion beneath the crater floor. The emplacement of a shallow magmatic body should result in a positive Bouguer anomaly relative to unaltered complex craters, a signal which is observed for the average Bouguer anomaly interior to the crater walls. We observe the Bouguer anomaly of floor-fractured craters on an individual basis using the unfiltered Bouguer gravity so...

    A promising strategy for reducing the incidence and severity of fall-related injuries in long-term care (LTC) is to decrease the ground surface stiffness, and the subsequent forces applied to the body parts at impact, through installation of compliant flooring. Evidence about the feasibility of compliant flooring in LTC is extremely limited. My PhD research addresses this gap by conducting a comprehensive, multimethod evaluation of compliant flooring. Specifically, I investigate the feasibili...

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

    Lothar Schlafer

    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.

  18. Management of disorders of the posterior pelvic floor.

    Berman, Loren; Aversa, John; Abir, Farshad; Longo, Walter E.

    2005-01-01

    INTRODUCTION: Constipation is a relatively common problem affecting 15 percent of adults in the Western world, and over half of these cases are related to pelvic floor disorders. This article reviews the clinical presentation and diagnostic approach to posterior pelvic floor disorders, including how to image and treat them. METHODS: A Pubmed search using keywords "rectal prolapse," "rectocele," "perineal hernia," and "anismus" was performed, and bibliographies of the revealed articles were cross-referenced to obtain a representative cross-section of the literature, both investigational studies and reviews, that are currently available on posterior pelvic floor disorders. DISCUSSION: Pelvic floor disorders can occur with or without concomitant physical anatomical defects, and there are a number of imaging modalities available to detect such abnormalities in order to decide on the appropriate course of treatment. Depending on the nature of the disorder, operative or non-operative therapy may be indicated. CONCLUSION: Correctly diagnosing pelvic floor disorders can be complex and challenging, and the various imaging modalities as well as clinical history and exam must be considered together in order to arrive at a diagnosis.

  20. State-of-the-art of development of floor spectra

    Singh, M.P.

    1984-01-01

    Floor spectra are used as seismic inputs for the design and qualification of subsystems and equipment. Until very recently, the time history analyses with single acceleration time history as input were very commonly used. However, this approach has been observed to give nonunique floor spectrum curves. Thus, as alternatives several direct approaches have been developed. The approaches which are based on the random vibration principles but employ response spectra directly have more rational appeal. Several such approaches are available. Four different approaches, employing the mode displacement and mode acceleration formulations, covering the proportionally as well as nonproportionally damped structures, are presented. The mode displacement formulations are most commonly used, although the mode acceleration formulations seem to be the better alternatives, both for the proportionally and nonproportionally damped structures. The need for the development of other forms of floor response spectra such as the relative velocity and relative acceleration spectra is also identified

    2000-01-01

    In the nuclear power sector, the main concern for the candidate countries entering the European Union, remains the nuclear safety. New standards and regulation will be issued for improving the general quality of life in a sound environment. For the candidate countries entering the European Union, this situation represents a real challenge. Their national legislation must be improved to meet the European standards. The conditions are different from country to country, and more difficult for those, which operate ''non west European reactor type''. The paper also present the actual status of the Romanian legislation related to nuclear power and environment. There are presented the principles, terms and responsibilities contained in this legislation. The authors discuss some aspects related to the possibilities to improve the national legislation to meet the actual European Commission or EURATOM standards. (author)

  2. Hummingbirds have a greatly enlarged hippocampal formation.

    Ward, Brian J; Day, Lainy B; Wilkening, Steven R; Wylie, Douglas R; Saucier, Deborah M; Iwaniuk, Andrew N

    Both field and laboratory studies demonstrate that hummingbirds (Apodiformes, Trochilidae) have exceptional spatial memory. The complexity of spatial-temporal information that hummingbirds must retain and use daily is probably subserved by the hippocampal formation (HF), and therefore, hummingbirds should have a greatly expanded HF. Here, we compare the relative size of the HF in several hummingbird species with that of other birds. Our analyses reveal that the HF in hummingbirds is significantly larger, relative to telencephalic volume, than any bird examined to date. When expressed as a percentage of telencephalic volume, the hummingbird HF is two to five times larger than that of caching and non-caching songbirds, seabirds and woodpeckers. This HF expansion in hummingbirds probably underlies their ability to remember the location, distribution and nectar content of flowers, but more detailed analyses are required to determine the extent to which this arises from an expansion of HF or a decrease in size of other brain regions.

    Akhtar, M.U.; Nazir, A.; Montmorency College of Dentistry, Lahore; Kiran, S.; Montmorency College of Dentistry, Lahore

    2014-01-01

    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)

  4. [Functional aspects of pelvic floor surgery].

    Wagenlehner, F M E; Gunnemann, A; Liedl, B; Weidner, W

    2009-11-01

    Pelvic floor dysfunctions are frequently seen in females. The human pelvic floor is a complex structure and heavily stressed throughout female life. Recent findings in the functional anatomy of the pelvic floor have led to a much better understand-ing, on the basis of which enormous improvements in the therapeutic options have arisen. The pelvic floor activity is regulated by three main muscular forces that are responsible for vaginal tension and suspension of the pelvic floor -organs, bladder and rectum. For different reasons laxity in the vagina or its supporting ligaments as a result of altered connective tissue can distort this functional anatomy. A variety of symptoms can derive from these pelvic floor dysfunctions, such as urinary urge and stress incontinence, abnormal bladder emptying, faecal incontinence, obstructive bowel disease syndrome and pelvic pain. Pelvic floor reconstruction is nowadays driven by the concept that in the case of pelvic floor symptoms restoration of the anatomy will translate into restoration of the physiology and ultimately improve the patients' symptoms. The exact surgical reconstruction of the anatomy is there-fore almost exclusively focused on the restoration of the lax pelvic floor ligaments. An exact identification of the anatomic lesions preoperatively is eminently necessary, to allow for an exact anatomic reconstruction with respect to the muscular forces of the pelvic floor.

  5. Peculiar enlargement of the nasopharynx in patients with anorexia nervosa

    Okamoto, K.; Ito, J.; Tokiguchi, S.; Kuwabara, G.; Nishihara, M.

    1995-01-01

    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

    Tang, Y.Z.; Bharwani, N.; Micco, M.; Akker, S.; Rockall, A.G.; Sahdev, A.

    2014-01-01

    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

    2007-01-01

    This study evaluates the economic effects of corporate tax coordination in the enlarged European Union (EU) using a computable general equilibrium model. Our main findings are as follows: (i) Corporate tax coordination can yield modest aggregate welfare gains. The 2004 enlargement of the EU has...... elaborate compensation mechanisms. (iii) The large and diverse country effects suggest that Enhanced Cooperation for a subset of the Member States may be the most likely route towards tax coordination. (iv) Identifying winners and losers from coordination for the purpose of a compensation mechanism may...

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

    Costa Mario Gesteira

    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.

    Noor, R.; Neelam, H.; Bashir, M.S.

    2017-01-01

    Objective: To compare pelvic floor dysfunction in non pregnant women who had delivered vaginally versus those with cesarean delivery. Methodology: The prevalence of pelvic floor disorders among non pregnant women was assesses by using a standardized tool pelvic floor distress inventory short form (PFDI-20). Data was collected from Jinnah Hospital Lahore, Pakistan. Results: Total numbers of participants were 278. 47.12% subjects had moderate, 36.69% miner and 16.19% had severe pelvic floor dysfunction. The symptoms of pelvic organ prolapse were more prevalent (mean value is 59.1876) than Urinary Distress (mean value is 40.5426), while the Colorectal-Anal Distress (mean value is 35.9150) were least prevalent. Conclusion: Pelvic floor disorders are very common among females and are strongly associated with mode of delivery. Although spontaneous vaginal birth was extensively associated with pelvic floor disorders the instrumental delivery affects most. (author)

  17. The Association between Residence Floor Level and Cardiovascular Disease: The Health and Environment in Oslo Study.

    Rohde, Mads K; Aamodt, Geir

    2016-01-01

    Background. Increasingly more people live in tall buildings and on higher floor levels. Factors relating to floor level may protect against or cause cardiovascular disease (CVD). Only one previous study has investigated the association between floor level and CVD. Methods. We studied associations between floor of bedroom and self-reported history of stroke, venous thromboembolism (VTE), and intermittent claudication (IC) among 12.525 inhabitants in Oslo, Norway. We fitted multivariate logistic regression models and adjusted for sociodemographic variables, socioeconomic status (SES), and health behaviors. Additionally, we investigated block apartment residents ( N = 5.374) separately. Results. Trend analyses showed that disease prevalence increased by floor level, for all three outcomes. When we investigated block apartment residents alone, the trends disappeared, but one association remained: higher odds of VTE history on 6th floor or higher, compared to basement and 1st floor (OR: 1.504; 95% CI: 1.007-2.247). Conclusion. Floor level is positively associated with CVD, in Oslo. The best-supported explanation may be residual confounding by building height and SES. Another explanation, about the impact of atmospheric electricity, is also presented. The results underline a need to better understand the associations between residence floor level and CVD and multistory housing and CVD.

  18. Sand Floor for Farmed Blue Foxes: Effects on Claws, Adrenal Cortex Function, Growth and Fur Properties

    Leena Ahola

    2009-01-01

    Full Text Available Farmed blue foxes (Vulpes lagopus are traditionally housed on mesh floors where they are unable to perform certain species-specific behaviours, such as digging, which may compromise the animals' welfare. This study describes how a possibility to use in-cage sand floor affects welfare-related variables like growth of the claws, adrenal cortex function, and fur properties in juvenile blue foxes. The foxes (N=32 were housed in male-female sibling pairs in an outdoor fur animal shed in cage systems consisting of two traditional fox cages. For the eight male-female sibling pairs of the Control group, there was a mesh floor in both cages of each cage system, whereas for the eight pairs of the Sand group there was a mesh floor in one cage and a 30–40 cm deep earth floor in the other cage. The results show that sand floor is beneficial for the wearing of the claws of foxes. Furthermore, an early experience of sand floor may have positive effects on the foxes' fur development. The results, however, also suggest that there might appear welfare problems observed as disturbed claw growth and increased adrenal cortex activation if foxes that are once provided with clean and unfrozen sand floor are not allowed to enjoy this floor all the time.

  19. Aerodynamic Analysis of Trailing Edge Enlarged Wind Turbine Airfoils

    Xu, Haoran; Yang, Hua; Liu, Chao; Shen, Wenzhong; Zhu, Weijun

    2014-01-01

    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 × 10 6 . 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. The steady results calculated by the fully turbulent k-ω SST, transitional k-ω SST model and RFOIL all show that with the increase of thickness of trailing edge, the linear region of lift is extended and the maximum lift also increases, the increase rate and amount of lift become limited gradually at low angles of attack, while the drag increases dramatically. For thicker airfoils with larger maximum thickness to chord length, the increment of lift is larger than that of relatively thinner airfoils when the thickness of blunt trailing edge is increased from 5% to 10% chord length. But too large lift can cause abrupt stall which is profitless for power output. The transient 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 transient calculations over-predict the lift at large angles of attack and drag at all angles of attack than the steady calculations which is likely to be caused by the artificial restriction of the flow in two dimensions

  20. Magnetic resonance imaging of pelvic floor dysfunction.

    2013-11-01

    Pelvic floor dysfunction is largely a complex problem of multiparous and postmenopausal women and is associated with pelvic floor or organ descent. Physical examination can underestimate the extent of the dysfunction and misdiagnose the disorders. Functional magnetic resonance (MR) imaging is emerging as a promising tool to evaluate the dynamics of the pelvic floor and use for surgical triage and operative planning. This article reviews the anatomy and pathology of pelvic floor dysfunction, typical imaging findings, and the current role of functional MR imaging. Copyright © 2013 Elsevier Inc.

    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.

  5. Strategy to avoid patient-prosthesis mismatch: aortic root enlargement.

    Srivastava, Dharmendra Kumar; Sanki, Prokash; Bhattacharya, Subhankar; Siddique, Javed Veqar

    2014-02-01

    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. Dual-stiffness flooring: can it reduce fracture rates associated with falls?

    Knoefel, Frank; Patrick, Louise; Taylor, Jodie; Goubran, Rafik

    2013-04-01

    Falls cause significant morbidity and mortality in long term care facilities. Dual-stiffness flooring (DSF) has previously shown promise in reducing such morbidity in experimental models. This study set out to measure the impact of SmartCell flooring on falls-related morbidity in a nursing home. All falls occurring at an Arizona nursing home between July 1, 2008, and December 31, 2010, were reviewed for age, sex, diagnosis of osteoporosis, number of medications, history of previous falls, type of flooring (normal vs DSF), time of day, type of injury, and resulting actions. Fall-related outcomes were compared across room types using chi-square and logistic regression methods. Eighty-two falls on the DSF were compared with 85 falls on the regular floor. There was a tendency for residents falling on DSF to have less bruising and abrasions, while having more redness and cuts. There were 2 fractures on regular flooring (2.4% fracture rate) and none on the DSF flooring (0% fracture rate). The fracture rate of 2.4% of falls on the regular floor is consistent with previous reports in the literature, whereas a 0% rate found on the DSF floor is a clinically significant improvement. This suggests that DSF may be a practical approach for institutions and consumers to reduce fall-related injuries. A larger scale controlled study to confirm these encouraging preliminary findings is warranted. Copyright © 2013 American Medical Directors Association, Inc. Published by Elsevier Inc.

  8. Characterization of the protective capacity of flooring systems using force-deflection profiling.

    Glinka, Michal N; Karakolis, Thomas; Callaghan, Jack P; Laing, Andrew C

    2013-01-01

    'Safety floors' aim to decrease the risk of fall-related injuries by absorbing impact energy during falls. Ironically, excessive floor deflection during walking or standing may increase fall risk. In this study we used a materials testing system to characterize the ability of a range of floors to absorb energy during simulated head and hip impacts while resisting deflection during simulated single-leg stance. We found that energy absorption for all safety floors (mean (SD)=14.8 (4.9)J) and bedside mats (25.1 (9.3)J) was 3.2- to 5.4-fold greater than the control condition (commercial carpet). While footfall deflections were not significantly different between safety floors (1.8 (0.7)mm) and the control carpet (3.7 (0.6)mm), they were significantly higher for two bedside mats. Finally, all of the safety floors, and two bedside mats, displayed 3-10 times the energy-absorption-to-deflection ratios observed for the baseline carpet. Overall, these results suggest that the safety floors we tested effectively addressed two competing demands required to reduce fall-related injury risk; namely the ability to absorb substantial impact energy without increasing footfall deflections. This study contributes to the literature suggesting that safety floors are a promising intervention for reducing fall-related injury risk in older adults. Copyright © 2012 IPEM.

  9. [Transient enlargement of craniopharyngioma cysts after stereotactic radiotherapy and radiosurgery].

    Mazerkina, N A; Savateev, A N; Gorelyshev, S K; Konovalov, A N; Trunin, Yu Yu; Golanov, A V; Medvedeva, O A; Kalinin, P L; Kutin, M A; Astafieva, L I; Krasnova, T S; Ozerova, V I; Serova, N K; Butenko, E I; Strunina, Yu V

    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).

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

    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.

  12. Laparoscopic Pelvic Floor Repair Using Polypropylene Mesh

    Shih-Shien Weng

    2008-09-01

    Conclusion: Laparoscopic pelvic floor repair using a single piece of polypropylene mesh combined with uterosacral ligament suspension appears to be a feasible procedure for the treatment of advanced vaginal vault prolapse and enterocele. Fewer mesh erosions and postoperative pain syndromes were seen in patients who had no previous pelvic floor reconstructive surgery.

    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.

  19. Enlarged cavum septum pellucidum as a neurodevelopmental marker in adolescent-onset opiate dependence.

    Jaeuk Hwang

    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.

  20. Influence of seasonality on the comfort supplied by different materials used as cubicle flooring for dairy cows

    P. De Palo

    2010-04-01

    Full Text Available The comfort provided by four different cubicle floorings was evaluated with a preference test in relation to winter and summer seasons. The test showed that polyethylene vinyl acetate and polypropylene vinyl acetate mats were preferred during winter, while solid manure and wood shavings assured more comfort than inorganic floorings during summer period. Results obtained suggest that the resting comfort of cubicle floorings may be evaluated also in relation to environmental microclimatic patterns.

  1. An anatomic risk model to screen post endovascular aneurysm repair patients for aneurysm sac enlargement.

    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.

  2. Asymmetric Meckel Cave Enlargement: A Potential Marker of PHACES Syndrome.

    Wright, J N; Wycoco, V

    2017-06-01

    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.

  3. 120 Years of U.S. Residential Housing Stock and Floor Space

    Pinto de Moura, Maria C.; Smith, Steven J.; Belzer, David B.

    2015-08-11

    Energy consumption in the residential sector accounts for one-fifth of total U.S. energy consumption and energy-related CO2 emissions. Floor space is a major driver of building energy demand. This paper develops a historical time series of total residential floor space for 1891-2010 and examines the role of socio-economic drivers GDP, population and household size on floor space. Using primarily data from the U.S. Census Bureau, we develop new construction and vintage-disaggregated housing stock for three building types, and address various data inconsistency issues. An examination of the long-term relationship of GDP and total residential floor space shows a remarkably constant trend over the period. While population increases five times over the period, a 50% decrease in household size contributes towards a tenfold increase in the number of housing units and floor space, while average floor space per unit remains surprisingly constant, as a result of housing retirement dynamics. In the last 30 years, however, these trends appear to be changing, as household size shows signs of leveling off, or even increasing again, while average floor space per unit has been increasing. Total residential sector primary energy consumption and floor space show a similar growth trend over the last 60 years.

  4. The floor effect: impoverished spatial memory for elevator buttons.

    Vendetti, Michael; Castel, Alan D; Holyoak, Keith J

    2013-05-01

    People typically remember objects to which they have frequently been exposed, suggesting that memory is a by-product of perception. However, prior research has shown that people have exceptionally poor memory for the features of some objects (e.g., coins) to which they have been exposed over the course of many years. Here, we examined how people remember the spatial layout of the buttons on a frequently used elevator panel, to determine whether physical interaction (rather than simple exposure) would ensure the incidental encoding of spatial information. Participants who worked in an eight-story office building displayed very poor recall for the elevator panel but above-chance performance on a recognition test. Performance was related to how often and how recently the person had used the elevator. In contrast to their poor memory for the spatial layout of the elevator buttons, most people readily recalled small distinctive graffiti on the elevator walls. In a more implicit test, the majority were able to locate their office floor and the eighth floor button when asked to point toward these buttons when in the actual elevator, with the button labels covered. However, identification was very poor for other floors (including the first floor), suggesting that even frequent interaction with information does not always lead to accurate spatial memory. These findings have implications for understanding the complex relationships among attention, expertise, and memory.

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

    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.

  6. Enlarged thalamostriate vein causing unilateral Monro foramen obstruction. Case report.

    Leonardo, Jody; Grand, Walter

    2009-06-01

    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.

  7. Western Balkan States and the European Union Enlargement

    Gelina Maliqi (Ramolli

    2011-07-01

    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.

  8. An education program about pelvic floor muscles improved women’s knowledge but not pelvic floor muscle function, urinary incontinence or sexual function: a randomised trial

    Roberta Leopoldino de Andrade

    2018-04-01

    Full Text Available Question: Does an educational program with instructions for performing ‘the Knack’ improve voluntary contraction of the pelvic floor muscles, reduce reports of urinary incontinence, improve sexual function, and promote women’s knowledge of the pelvic floor muscles? Design: Randomised, controlled trial with concealed allocation, intention-to-treat analysis and blinded assessors. Participants: Ninety-nine women from the local community. Intervention: The experimental group (n = 50 received one lecture per week for 4 weeks, and instructions for performing ‘the Knack’. The control group (n = 49 received no intervention. Outcome measures: The primary outcome was maximum voluntary contraction of the pelvic floor muscles measured using manometry. Secondary outcomes were: ability to contract the pelvic floor muscles measured using vaginal palpation; severity of urinary incontinence measured by the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF scored from 0 to 21; self-reported sexual function; and knowledge related to the pelvic floor. Outcomes were measured at baseline and after 4 weeks. Results: The intervention did not significantly improve: maximum voluntary contraction (MD 2.7 cmH2O higher in the experimental group, 95% CI –0.5 to 5.9; ability to contract the pelvic floor muscles (RR 2.18, 95% CI 0.49 to 9.65; or self-reported severity of urinary incontinence (MD 1 point greater reduction in the experimental group, 95% CI –3 to 1. Sexual function did not significantly differ between groups, but very few of the women engaged in sexual activity during the study period. The educational program did, however, significantly increase women’s knowledge related to the location, functions and dysfunctions of the pelvic floor muscles, and treatment options. Conclusion: Education and teaching women to perform ‘the Knack’ had no significant effect on voluntary contraction of the pelvic floor muscles

  9. Simulations of floor cooling system capacity

    Odyjas, Andrzej; Górka, Andrzej

    2013-01-01

    Floor cooling system capacity depends on its physical and operative parameters. Using numerical simulations, it appears that cooling capacity of the system largely depends on the type of cooling loads occurring in the room. In the case of convective cooling loads capacity of the system is small. However, when radiation flux falls directly on the floor the system significantly increases productivity. The article describes the results of numerical simulations which allow to determine system capacity in steady thermal conditions, depending on the type of physical parameters of the system and the type of cooling load occurring in the room. Moreover, the paper sets out the limits of system capacity while maintaining a minimum temperature of the floor surface equal to 20 °C. The results are helpful for designing system capacity in different type of cooling loads and show maximum system capacity in acceptable thermal comfort condition. -- Highlights: ► We have developed numerical model for simulation of floor cooling system. ► We have described floor system capacity depending on its physical parameters. ► We have described floor system capacity depending on type of cooling loads. ► The most important in the obtained cooling capacities is the type of cooling loads. ► The paper sets out the possible maximum cooling floor system capacity

  10. Pelvic floor and sexual male dysfunction

    Antonella Pischedda

    2013-04-01

    Full Text Available The pelvic floor is a complex multifunctional structure that corresponds to the genito- urinary-anal area and consists of muscle and connective tissue. It supports the urinary, fecal, sexual and reproductive functions and pelvic statics. The symptoms caused by pelvic floor dysfunction often affect the quality of life of those who are afflicted, worsening significantly more aspects of daily life. In fact, in addition to providing support to the pelvic organs, the deep floor muscles support urinary continence and intestinal emptying whereas the superficial floor muscles are involved in the mechanism of erection and ejaculation. So, conditions of muscle hypotonia or hypertonicity may affect the efficiency of the pelvic floor, altering both the functionality of the deep and superficial floor muscles. In this evolution of knowledge it is possible imagine how the rehabilitation techniques of pelvic floor muscles, if altered and able to support a voiding or evacuative or sexual dysfunction, may have a role in improving the health and the quality of life.

  11. Isolated amygdala enlargement in temporal lobe epilepsy: A systematic review.

    Beh, S M Jessica; Cook, Mark J; D'Souza, Wendyl J

    2016-07-01

    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

  12. The mechanical ventilation of suspended timber floors for radon remediation - a simple analysis

    Woolliscroft, M.

    1994-01-01

    Mechanical ventilation of the underfloor space is one of the most effective ways of reducing radon levels in buildings with suspended timber floors. There is a question, however, whether this ventilation should be supply or extract, sometimes extract is more effective, sometimes supply is more effective. This report presents a simple analysis of the problem and suggests the hypothesis that the relative effectiveness of supply or extract ventilation to the underfloor space depends on the relative airtightness of the floor and the soil or oversite surface. The analysis suggests that if the floor is relatively tight then supply ventilation may be more effective whereas if the floor is relatively leaky or there is oversite concrete then extract may be better. It is suggested that in either case it is better to keep the underfloor pressure low and that when mechanical ventilation is provided to the underfloor space it may be necessary to increase the number of airbricks.

    2012-01-01

    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.

  19. Cooperative diplomacy: Citizens, sovereignty, and the logic of democratic enlargement

    Ndungu, Anthony Mark

    2000-12-01

    The contemporary theory of international regimes holds that governments collaborate when they reach a consensus on a centralized supervisory mechanism for resolving compliance, monitoring, and distributive questions. Yet, in the least likely case of international nuclear security, governments have repeatedly established major international regimes without such a consensus, even though undetected defection would impose substantial long-term costs on those continuing to comply, and seriously complicate attempts at retaliation. For example, despite more than ten years of almost continuous East-West negotiations, governments could not reach a consensus on the compliance questions related to the International Atomic Energy Agency's (IAEA) safeguards regime. Yet, threshold and potential nuclear powers, such as France and India, respectively, exempted themselves from the IAEA's safeguards regime, but gained access to the knowledge, facilities and materials intended exclusively for full participants. Similarly, France, Italy, and Germany failed to agree on a centralized mechanism for supervising the production of nuclear warheads for a Western European nuclear force. Indeed, even the member states of the European Atomic Energy Community (EURATOM) could not agree on an effective centralized mechanism for supervising the regional production of fissionable materials. Yet, under the 1958 United States-EURATOM Nuclear Cooperation agreement, the United States agreed to expand its sales of enriched uranium and other special nuclear materials to the discordant members of EURATOM, who jointly assumed responsibility for an independent regional system of safeguards. Finally, the U.S. and Soviet governments could not agree on a centralized mechanism for solving the compliance questions related to the Partial Test Ban Treaty concluded in 1963, but the two superpowers and the U.K. left the resolution of those questions to the domestic authorities of the signatory states.

    Falls are an issue disproportionately affecting older people who are at increased risk of falls and injury. This protocol describes a pilot study investigating shock-absorbing flooring for fall-related injuries in wards for older people. To inform future research by evaluating fall-related injuries on the intervention and existing flooring, assessing the sustainability of the flooring in ward environments, estimating the cost-effectiveness of the floor and assessing how the floor affects patients and other users. This study uses mixed methods a pilot cluster randomised controlled trial, observation via mechanical testing and interviews. Eight participating wards (clusters) are randomised using a computer-generated list. No blinding is incorporated into the study. Each site has a baseline period of approximately 6 months. Then, four sites receive the intervention floor, while four continue using standard floors. Sites are then followed up for approximately 1 year. Any person admitted to a bed in the 'study area' of a participating ward can be entered into the trial. Orientated patients, visitors and any hospital staff who use the floor in a study area are eligible for inclusion in an interview. An 8.3 mm thick vinyl floor covering with polyvinyl chloride foam backing (Tarkett Omnisports EXCEL). The primary outcome is fall-related injuries. Severity of injuries, falls, cost-effectiveness, user views and mechanical performance (shock absorbency and slip resistance) are also being assessed.

    Does an educational program with instructions for performing 'the Knack' improve voluntary contraction of the pelvic floor muscles, reduce reports of urinary incontinence, improve sexual function, and promote women's knowledge of the pelvic floor muscles? Randomised, controlled trial with concealed allocation, intention-to-treat analysis and blinded assessors. Ninety-nine women from the local community. The experimental group (n=50) received one lecture per week for 4 weeks, and instructions for performing 'the Knack'. The control group (n=49) received no intervention. The primary outcome was maximum voluntary contraction of the pelvic floor muscles measured using manometry. Secondary outcomes were: ability to contract the pelvic floor muscles measured using vaginal palpation; severity of urinary incontinence measured by the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) scored from 0 to 21; self-reported sexual function; and knowledge related to the pelvic floor. Outcomes were measured at baseline and after 4 weeks. The intervention did not significantly improve: maximum voluntary contraction (MD 2.7 cmH 2 O higher in the experimental group, 95% CI -0.5 to 5.9); ability to contract the pelvic floor muscles (RR 2.18, 95% CI 0.49 to 9.65); or self-reported severity of urinary incontinence (MD 1 point greater reduction in the experimental group, 95% CI -3 to 1). Sexual function did not significantly differ between groups, but very few of the women engaged in sexual activity during the study period. The educational program did, however, significantly increase women's knowledge related to the location, functions and dysfunctions of the pelvic floor muscles, and treatment options. Education and teaching women to perform 'the Knack' had no significant effect on voluntary contraction of the pelvic floor muscles, urinary incontinence or sexual function, but it promoted women's knowledge about the pelvic floor.

    Katsetos, Christos D; Bianchi, Michael A; Jaffery, Fizza; Koutzaki, Sirma; Zarella, Mark; Slater, Robert

    2014-06-01

    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.

  6. 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

  8. Unusual presentation of hidradenitis suppurativa with massive enlargement of penis.

    Baughman, Steven M; Cespedes, R Duane

    2004-08-01

    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.

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

    Ana Tobar

    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-related

  10. Modelling the cost-effectiveness of impact-absorbing flooring in Swedish residential care facilities.

    Ryen, Linda; Svensson, Mikael

    2016-06-01

    Fall-related injuries among the elderly, specifically hip fractures, cause significant morbidity and mortality as well as imposing a substantial financial cost on the health care system. Impact-absorbing flooring has been advocated as an effective method for preventing hip fractures resulting from falls. This study identifies the cost-effectiveness of impact-absorbing flooring compared to standard flooring in residential care facilities for the elderly in a Swedish setting. An incremental cost-effectiveness analysis was performed comparing impact-absorbing flooring to standard flooring using a Markov decision model. A societal perspective was adopted and incremental costs were compared to incremental gains in quality-adjusted life years (QALYs). Data on costs, probability transitions and health-related quality of life measures were retrieved from the published literature and from Swedish register data. Probabilistic sensitivity analysis was performed through a Monte Carlo simulation. The base-case analysis indicates that the impact-absorbing flooring reduces costs and increases QALYs. When allowing for uncertainty we find that 60% of the simulations indicate that impact-absorbing flooring is cost-saving compared to standard flooring and an additional 20% that it has a cost per QALY below a commonly used threshold value : Using a modelling approach, we find that impact-absorbing flooring is a dominant strategy at the societal level considering that it can save resources and improve health in a vulnerable population. © The Author 2015.

  11. Investigating the fall-injury reducing effect of impact absorbing flooring among female nursing home residents: initial results.

    Gustavsson, Johanna; Bonander, Carl; Andersson, Ragnar; Nilson, Finn

    2015-10-01

    Fall-related injuries affect the lives of elderly to a substantial degree. This quasi-experimental study investigates the fall-injury reducing effect of impact absorbing flooring among female nursing home residents. The intervention site is a nursing home in Sweden where impact absorbing flooring was installed in parts of one of six wards (six out of 10 apartments (excluding bathrooms), the communal dining-room and parts of the corridor). The impact absorbing flooring is a 12 mm thick closed cell flexible polyurethane/polyurea composite tile (500×500 mm) with an exterior surface of polyurethane/polyurea. A generalised linear model (log-binomial) was used to calculate the RR of injury from falls on impact absorbing flooring compared to falls on regular flooring, adjusted for age, body mass index, visual and cognitive impairments. During the study period (1 October 2011 to 31 March 2014), 254 falls occurred on regular flooring and 77 falls on impact absorbing flooring. The injury/fall rate was 30.3% for falls on regular flooring and 16.9% for falls on impact absorbing flooring. Adjusted for covariates, the impact absorbing flooring significantly reduced the RR of injury in the event of a fall by 59% (RR 0.41 (95% Cl 0.20 to 0.80)). This is, to our knowledge, the first study evaluating the injury-reducing effect of impact absorbing flooring in a nursing home showing statistically significant effect. The results from this study are promising, indicating the considerable potential of impact absorbing flooring as a fall-related injury intervention among frail elderly.

  12. Study protocol for the Flooring for Injury Prevention (FLIP) Study: a randomised controlled trial in long-term care.

    Lachance, Chantelle C; Feldman, Fabio; Laing, Andrew C; Leung, Pet Ming; Robinovitch, Stephen N; Mackey, Dawn C

    2016-12-01

    A promising strategy for reducing the incidence and severity of fall-related injuries in long-term care (LTC) is to decrease the ground surface stiffness, and the subsequent forces applied to the body parts at impact, through installation of compliant flooring that does not substantially affect balance or mobility. Definitive evidence of the effects of compliant flooring on fall-related injuries in LTC is lacking. The Flooring for Injury Prevention (FLIP) Study is designed to address this gap. The FLIP Study is a 4-year, parallel-group, 2-arm, randomised controlled superiority trial of flooring in 150 resident rooms at a LTC site. The primary objective is to determine whether compliant flooring reduces serious fall-related injuries relative to control flooring. Intervention (2.54 cm SmartCells compliant; 74 rooms) and control (2.54 cm plywood; 76 rooms) floorings were installed over the top of existing concrete floors and covered with identical 2.00 mm vinyl. The primary outcome is serious fall-related injury, defined as any impact-related injury due to a fall in a study room that results in Emergency Department visit or hospital admission. Secondary outcomes include minor fall-related injury, any fall-related injury, falls, number of fallers, fractures, and healthcare utilisation and costs for serious fall-related injuries. Randomisation of study rooms, and residents in rooms, was stratified by residential unit, and flooring assignments were concealed. Outcome ascertainment began September 2013. Results from the FLIP Study will provide evidence about the effects of compliant flooring on fall-related injuries in LTC and will guide development of safer environments for vulnerable older adults.

  16. Diversity of life in ocean floor basalt

    Thorseth, I. H.; Torsvik, T.; Torsvik, V.; Daae, F. L.; Pedersen, R. B.

    2001-12-01

    Electron microscopy and biomolecular methods have been used to describe and identify microbial communities inhabiting the glassy margins of ocean floor basalts. The investigated samples were collected from a neovolcanic ridge and from older, sediment-covered lava flows in the rift valley of the Knipovich Ridge at a water depth around 3500 m and an ambient seawater temperature of -0.7°C. Successive stages from incipient microbial colonisation, to well-developed biofilms occur on fracture surfaces in the glassy margins. Observed microbial morphologies are various filamentous, coccoidal, oval, rod-shaped and stalked forms. Etch marks in the fresh glass, with form and size resembling the attached microbes, are common. Precipitation of alteration products around microbes has developed hollow subspherical and filamentous structures. These precipitates are often enriched in Fe and Mn. The presence of branching and twisted stalks that resemble those of the iron-oxidising Gallionella, indicate that reduced iron may be utilised in an energy metabolic process. Analysis of 16S-rRNA gene sequences from microbes present in the rock samples, show that the bacterial population inhabiting these samples cluster within the γ- and ɛ-Proteobacteria and the Cytophaga/Flexibacter/Bacteroides subdivision of the Bacteria, while the Archaea all belong to the Crenarchaeota kingdom. This microbial population appears to be characteristic for the rock and their closest relatives have previously been reported from cold marine waters in the Arctic and Antarctic, deep-sea sediments and hydrothermal environments.

  17. Dance floors as injury risk: analysis and evaluation of acute injuries caused by dance floors in professional dance with regard to preventative aspects.

    Wanke, Eileen M; Mill, Helmgard; Wanke, Alice; Davenport, Jaqueline; Koch, Franziska; Groneberg, David A

    2012-09-01

    A dance floor is often the only support of movements in dance. A dance floor surface that shows deficiencies, can result in acute injuries and chronic problems. Although the significance of an adequate dance floor is well known, there is still a lack of differentiated analyses of dance floor-related acute injuries. This study presents data on acute injuries exclusively caused by the dance floor. The data were obtained from standardized work accident reports from consultants (F 1000), documentary accident records from all Berlin theatres, a state ballet school (n=2,281), and case records from the Berlin State Accident Insurance (UKB) covering a period of 17 years. All analyses and descriptive statistics were conducted with Excel 2007 and SPSS 18. Dance floor surfaces were the causative factor in 12.8% of all accidents (n=291, female 183, male 108). Almost two thirds (62.6%) of all accidents in professional dancers happened on stage, and almost half (49.5%) occurred during performances. As for causative factors, 53.1% of the professional dancers (P) and 42.5% of the dance students (S) claimed that the floor had been "too slippery," with "getting stuck" or (tripping) as the second most common problem (P 18.4%, S 11.3%). Of the injured dancers, 41.8% were older than 30 years and can therefore be categorized as experienced. Dance floors play a significant role in the occurrence of acute injuries, even in experienced dancers. Performances on stage seem to be a particular risk. However, injury prevention measures should include all work locations (P) as well as non-dance-specific locations (S).

    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.

  19. Investigation of floor Nusselt number in floor heating system for insulated ceiling conditions

    Karadag, Refet; Teke, Ismail

    2007-01-01

    In this study, in a floor heated room, natural convection heat transfer over the floor is analysed numerically for different thermal conditions. An equation relevant to Nusselt number over the floor has been obtained by using the numerical data. Different equations are given in the literature. They consider the effect of floor Rayleigh number while neglecting the effect of wall and ceiling thermal conditions. Numerical data obtained in this study show that the Nusselt number over the floor depends on not only the floor Rayleigh number but also the wall Rayleigh number (for insulated ceiling conditions). The equations given in the literature are different from each other due to their not considering the effect of wall and ceiling Rayleigh numbers. This difference between the equations may be eliminated by obtaining an equation containing the effect of floor, wall and ceiling Rayleigh numbers. In this new approach, an equation relevant to the floor Nusselt number that depends on the floor and wall Rayleigh numbers has been obtained in the floor heating system for insulated ceiling conditions. The equation obtained in this study has been compared with the equations given in the literature. It has been seen that the equation obtained in this study matches the numerical values under more extensive thermal conditions than the equations given in the literature. The maximum deviation for the equations given in the literature is 35%, but in the current study, the maximum deviation has been found to be 10%. As a result, it is more convenient to use the equation found in the new approach as a function of Rayleigh number over the floor and wall for insulated ceiling conditions

  20. Effect of pelvic floor rehabilitation technique in preventing the postpartum pelvic floor dysfunction

    Shi-Qiong Li

    2017-04-01

    Full Text Available Objective: To explore the effect of pelvic floor rehabilitation technique in preventing the postpartum pelvic floor dysfunction and on the sexual life quality. Methods: A total of 286 puerpera with pelvic floor dysfunction who were admitted in our hospital from May, 2014 to May, 2015 42 d after delivery were included in the study, and randomized into the treatment group and the control group with 143 cases in each group. After guidance, the puerpera in the control group were given pelvic floor muscle training by themselves at home. On this basis, the puerpera in the treatment group were treated by the pelvic floor rehabilitation apparatus. The puerpera in the two groups were treated for 4 weeks. The pelvic floor function before treatment, 6 months and 1 year after delivery was detected. The color Doppler ultrasound apparatus was used to detect BSD, PUVA, UVJ-M, and BND 3 months after delivery. Results: BND, PUVA-R, PUVA-S, and UVJ-M 3 months after delivery in the treatment groups were significantly lower than those in the control group, while BSD-S was significantly higher than that in the control group. The improvement of type I and II muscle fiber fatigue (%, POP-Q degree, AP indication point (cm, and vaginal dynamic pressure (cmH2O was significantly superior to that in the control group. The comparison of pelvic floor muscle strength classification before treatment between the two groups was not statistically significant. After treatment, the pelvic floor muscle in the two groups was significantly strengthened, and the proportion of V grade patients was significantly increased when compared with before treatment. Conclusions: The postpartum early pelvic floor rehabilitation technique can effectively enhance the pelvic floor function, and prevent the postpartum pelvic floor dysfunction, with an accurate efficacy; therefore, it deserves to be widely recommended in the clinic.

  1. The Role of Pelvic Floor Muscles in Male Sexual Dysfunction and Pelvic Pain.

    Cohen, Deborah; Gonzalez, Joshua; Goldstein, Irwin

    2016-01-01

    Sexual function is essential to good health and well-being in men. The relationship between male sexual function, pelvic floor function, and pelvic pain is complex and only beginning to be appreciated. The objectives of the current review are to examine these complex relationships, and to demonstrate how pelvic floor physical therapy can potentially improve the treatment of various male sexual dysfunctions, including erectile dysfunction and dysfunction of ejaculation and orgasm. Contemporary data on pelvic floor anatomy and function as they relate to the treatment of various male sexual dysfunctions were reviewed. Examination of evidence supporting the association between the male pelvic floor and erectile dysfunction, ejaculatory/orgasmic dysfunction, and chronic prostatitis/chronic pelvic pain syndrome, respectively. Evidence suggests a close relationship between the pelvic floor and male sexual dysfunction and a potential therapeutic benefit from pelvic floor therapy for men who suffer from these conditions. Pelvic floor physical therapy is a necessary tool in a more comprehensive bio-neuromusculoskeletal-psychosocial approach to the treatment of male sexual dysfunction and pelvic pain.

  2. Sea-floor morphology and sedimentary environments in southern Narragansett Bay, Rhode Island

    McMullen, Katherine Y.; Poppe, Lawrence J.; Blackwood, Dann S.; Nardi, Matthew J.; Andring, Matthew A.

    2015-09-09

    Multibeam echosounder data collected by the National Oceanic and Atmospheric Administration along with sediment samples and still and video photography of the sea floor collected by the U.S. Geological Survey were used to interpret sea-floor features and sedimentary environments in southern Narragansett Bay, Rhode Island, as part of a long-term effort to map the sea floor along the northeastern coast of the United States. Sea-floor features include rocky areas and scour depressions in high-energy environments characterized by erosion or nondeposition, and sand waves and megaripples in environments characterized by coarse-grained bedload transport. Two shipwrecks are also located in the study area. Much of the sea floor is relatively featureless within the resolution of the multibeam data; sedimentary environments in these areas are characterized by processes associated with sorting and reworking. This report releases bathymetric data from the multibeam echosounder, grain-size analyses of sediment samples, and photographs of the sea floor and interpretations of the sea-floor features and sedimentary environments. It provides base maps that can be used for resource management and studies of topics such as benthic ecology, contaminant inventories, and sediment transport.

  3. Systematic evaluations of probabilistic floor response spectrum generation

    Lilhanand, K.; Wing, D.W.; Tseng, W.S.

    1985-01-01

    The relative merits of the current methods for direct generation of probabilistic floor response spectra (FRS) from the prescribed design response spectra (DRS) are evaluated. The explicit probabilistic methods, which explicitly use the relationship between the power spectral density function (PSDF) and response spectra (RS), i.e., the PSDF-RS relationship, are found to have advantages for practical applications over the implicit methods. To evaluate the accuracy of the explicit methods, the root-mean-square (rms) response and the peak factor contained in the PSDF-RS relationship are systematically evaluated, especially for the narrow-band floor spectral response, by comparing the analytical results with simulation results. Based on the evaluation results, a method is recommended for practical use for the direct generation of probabilistic FRS. (orig.)

    McCord, Samuel A [Sandia National Lab. (SNL-NM), Albuquerque, NM (United States). Waste Management and Pollution Prevention

    2015-04-01

    Following a building-wide waste assessment in September, 2014, and subsequent presentation to Sandia leadership regarding the goal of Zero Waste by 2025, the occupants of the IPOC Second Floor, West Wing contacted the Materials Sustainability and Pollution Prevention (MSP2) team to guide them to Zero Waste in advance of the rest of the site. The occupants are from Center 3600, Public Relations and Communications , and Center 800, Independent Audit, Ethics and Business Conduct . To accomplish this, MSP2 conducted a new limited waste assessment from March 2-6, 2015 to compare the second floor, west wing to the building as a whole. The assessment also serves as a baseline with which to mark improvements in diversion in approximately 6 months.

    1984-01-01

    A structural evaluation of the behavior of a Boiling Water Reactor operating floor subjected to postulated heavy load impact is presented relative to the evaluation of nuclear industry requirements for addressing the safe handling of heavy loads. A methodology for evaluation of important modes of structural response is presented along with a specification of performance limits that are consistent with desired functional requirements of the operating floor system. Options for improving undesirable behavior are discussed based upon an understanding of the physical phenomena involved, ultimately factoring this into a modification program. Reference is made to recent test experience that is applicable to the improvement of structural performance in modes of high shear ductility. Other relevant information is referenced that is applicable to the overall structural evaluation of nuclear power plant heavy load handling operations

    Khan, Aqsa A; Sevilla, Claudia; Wieslander, Cecilia K; Moran, Meghan B; Rashid, Rezoana; Mittal, Brita; Maliski, Sally L; Rogers, Rebecca G; Anger, Jennifer T

    2013-01-01

    The purpose of our study was to evaluate barriers in communication and disease understanding among office staff and interpreters when communicating with Spanish-speaking women with pelvic floor disorders. We conducted a qualitative study to evaluate barriers to communication with Spanish-speaking women with pelvic floor disorders among office staff and interpreters. Sixteen office staff and interpreters were interviewed; interview questions focused on experiences with Spanish-speaking patients with pelvic floor disorders in the clinic setting. Interview transcripts were analyzed qualitatively using grounded theory methodology. Analysis of the interview transcripts revealed several barriers in communication as identified by office staff and interpreters. Three major classes were predominant: patient, interpreter, and system-related barriers. Patient-related barriers included a lack of understanding of anatomy and medical terminology and inhibited discussions due to embarrassment. Provider-related barriers included poor interpreter knowledge of pelvic floor vocabulary and the use of office staff without interpreting credentials. System-related barriers included poor access to information. From these preliminary themes, an emergent concept was revealed: it is highly likely that Spanish-speaking women with pelvic floor disorders have poor understanding of their condition owing to multiple obstacles in communication. There are many levels of barriers to communications with Latin women treated for pelvic floor disorders, arising from the patient, interpreter, and the system itself. These barriers contribute to a low level of understanding of their diagnosis, treatment options, and administered therapies.

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

    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.

  13. 120 Years of U.S. Residential Housing Stock and Floor Space.

    Maria Cecilia P Moura

    Full Text Available Residential buildings are a key driver of energy consumption and also impact transportation and land-use. Energy consumption in the residential sector accounts for one-fifth of total U.S. energy consumption and energy-related CO2 emissions, with floor space a major driver of building energy demands. In this work a consistent, vintage-disaggregated, annual long-term series of U.S. housing stock and residential floor space for 1891-2010 is presented. An attempt was made to minimize the effects of the incompleteness and inconsistencies present in the national housing survey data. Over the 1891-2010 period, floor space increased almost tenfold, from approximately 24,700 to 235,150 million square feet, corresponding to a doubling of floor space per capita from approximately 400 to 800 square feet. While population increased five times over the period, a 50% decrease in household size contributed towards a tenfold increase in the number of housing units and floor space, while average floor space per unit remains surprisingly constant, as a result of housing retirement dynamics. In the last 30 years, however, these trends appear to be changing, as household size shows signs of leveling off, or even increasing again, while average floor space per unit has been increasing. GDP and total floor space show a remarkably constant growth trend over the period and total residential sector primary energy consumption and floor space show a similar growth trend over the last 60 years, decoupling only within the last decade.

  14. Glazed Tiles as Floor Finish in Nigeria

    Toyin Emmanuel AKINDE

    2013-09-01

    Full Text Available Tile is no doubt rich in antiquity; its primordial  show, came as mosaic with primary prospect in sacred floor finish before its oblivion, courtesy of, later consciousness towards wall finish in banquets, kitchens, toilets, restaurants and even bars. Today, its renaissance as floor finish is apparent in private and public architectural structures with prevalence in residential, recreational, commercial, governmental and other spaces. In Nigeria, the use of glazed tiles as floor finish became apparent, supposedly in mid-twentieth century; and has since, witnessed ever increasing demands from all sundry; a development that is nascent and has necessitated its mass  production locally with pockets of firms in the country. The latter however, is a resultant response to taste cum glazed tiles affordability, whose divergent sophistication in design, colour, size and shape is believed preferred to terrazzo, carpet and floor flex tile. Accessible as glazed tile and production is, in recent times; its dearth of a holistic literature in Nigeria is obvious. In the light of the latter, this paper examine glazed tiles as floor finish in Nigeria, its advent, usage, production, challenge, benefit and prospect with the hope of opening further frontier in discipline specifics.

  15. Global floor planning approach for VLSI design

    LaPotin, D.P.

    1986-01-01

    Within a hierarchical design environment, initial decisions regarding the partitioning and choice of module attributes greatly impact the quality of the resulting IC in terms of area and electrical performance. This dissertation presents a global floor-planning approach which allows designers to quickly explore layout issues during the initial stages of the IC design process. In contrast to previous efforts, which address the floor-planning problem from a strict module placement point of view, this approach considers floor-planning from an area planning point of view. The approach is based upon a combined min-cut and slicing paradigm, which ensures routability. To provide flexibility, modules may be specified as having a number of possible dimensions and orientations, and I/O pads as well as layout constraints are considered. A slicing-tree representation is employed, upon which a sequence of traversal operations are applied in order to obtain an area efficient layout. An in-place partitioning technique, which provides an improvement over previous min-cut and slicing-based efforts, is discussed. Global routing and module I/O pin assignment are provided for floor-plan evaluation purposes. A computer program, called Mason, has been developed which efficiently implements the approach and provides an interactive environment for designers to perform floor-planning. Performance of this program is illustrated via several industrial examples

  16. WOODEN FLOORING – BETWEEN PRESENT AND FUTURE

    Ivan CISMARU

    2015-06-01

    Full Text Available The paper aims at presenting a systematization of the wood floors, both in terms of the areas of application, and in terms of the fastening solutions and structures in constructions. In this respect, an extensive bibliographic research was achieved, on the researchers’ preoccupations. Starting from the current situation and forecasting the future, from the point of view of the chances held by wooden flooring, in competition with other types of materials, we dare say the wooden flooring or the wood in combination with other materials are not likely to be eliminated from the “civil-engineering market”. The wood floors are likely to develop as an application, especially in the area of the “special floors”, specific to the indoor sports or social halls; and even for some industrial sectors, with strict operating conditions (elasticity, thermal insulation, soundproofing that cannot be provided by other types of materials or structures. Starting from this last observation, the paper also aims at submitting current opinions with respect to this type of floors, both in the light of the current databases and in the light of the future researches, to this end

  17. Effects of Floor Covering Resistance of a Radiant Floor on System Energy and Exergy Performances

    Kazanci, Ongun Berk; Shukuya, Masanori; Olesen, Bjarne W.

    2016-01-01

    Floor covering resistance (material and thickness) can be influenced by subjective choices (architectural design, interior design, texture, etc.) with significant effects on the performance of a radiant heating and cooling system. To study the effects of floor covering resistance on system...... performance, a water-based radiant floor heating and cooling system (dry, wooden construction) was considered to be coupled to an air-to-water heat pump, and the effects of varying floor covering resistances (0.05 m2K/W, 0.09 m2K/W and 0.15 m2K/W) on system performance were analyzed in terms of energy...... and exergy. In order to achieve the same heating and cooling outputs, higher average water temperatures are required in the heating mode (and lower temperatures in the cooling mode) with increasing floor covering resistance. These temperature requirements decrease the heat pump’s performance (lower...

  18. Multivariate analysis of morphological pathology in ventricular enlargement by computed tomography

    Iwasaki, Satoru

    1981-01-01

    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.)

  19. Right heart enlargement in heartworm-infected dogs: a radiographic, electrocardiographic, and echocardiographic correlation

    Lombard, C.W.; Ackerman, N.

    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.

    2010-01-01

    The Dermoid cyst account for the 0.01 % of all cysts of buccal cavity. Its more frequent location is in the mouth floor. This is the case of a female patient aged 19 who approximately 7 years noted an increase of volume under tongue growing gradually and noting outside face and the discomfort at to speak and to chew. Complementary studies were conducted and under general anesthesia a surgical exeresis was carried out by intrabuccal approach achieving excellent esthetic and functional results. Histopathologic diagnosis matched with a dermoid cyst of mouth floor. Patient has not lesion recurrence after three years after operation. We conclude that the Dermoid cyst of mouth floor appear as benign tumor of middle line. The intrabuccal exeresis demonstrates esthetic and functional benefits. (author)

  2. Development of rationalized system treating floor drain

    Nakamura, Yasuyuki; Serizawa, Kenichi; Komatsu, Akihiro; Shimizu, Takayuki

    1998-01-01

    Radioactive liquid wastes generated at BWR plants are collected and treated as required. These days, however, generation of floor drain has deceased and HFF (Hollow Fiber Filter) has experienced a wide applicability to several kinds of liquid wastes. We should consider that the floor drain can be mixed and diluted with equipment drain and be purified by HFF. That enables some of the sumps and long priming pipes to be combined. From this point of view, we have developed a highly rationalized waste liquid system. We have evaluated the applicability of this system after an investigation into the generation and properties of floor drain and equipment drain at the latest BWR'S and an on-site test at a typical BWR.

  5. Uptake of thallium-201 in enlarged thyroid glands. Concise communication

    Fukuchi, M.; Kido, A.; Hyodo, K.; Tachibana, K.; Onoue, K.; Morita, T.; Nagai, K.

    1979-01-01

    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

  6. Hemorrhage from an enlarged emphysematous bulla during commercial air travel.

    Chen, Chien-Wen; Perng, Wann-Cherng; Li, Min-Hui; Yan, Horng-Chin; Wu, Chin-Pyng

    2006-12-01

    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.

  10. An alternative procedure for direct generation of seismic floor spectra

    Singh, M.P.; Sharma, A.M.

    1983-01-01

    Several approaches have been developed for generation of floor spectra which do not require seismic inputs in the form of acceleration time histories but can use a prescribed set of ground response spectra directly. These approaches are often referred to as direct approaches. Most of these approaches are based on the method of mode displacement of structural dynamics. Some problems can, however, occur with these approaches if the response of a system is affected by the high frequency modes and if these modes are omitted from the analyses. Herein an alternative approach based on the method of mode acceleration is proposed wherein the effect of high frequency modes is correctly included without their explicit evaluation. The seismic inputs in this approach are required to be prescribed in terms of relative acceleration and velocity spectra. The approach is very effective for the calculation of floor spectra for structural systems which have significant contribution from high frequency modes, and also for floors close to the base which are usually affected by the higher modes. In other cases too, this approach has been shown to provide better results than the mode displacement approach for a given number of modes used in the analysis. Thus, a general use of this approach in lieu of the mode displacement approach is advocated. (orig.)

  11. Customization of the voice prosthesis to prevent leakage from the enlarged tracheoesophageal puncture: results of a prospective trial.

    Lewin, Jan S; Hutcheson, Katherine A; Barringer, Denise A; Croegaert, Lindsay E; Lisec, Asher; Chambers, Mark S

    2012-08-01

    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.

  12. Left Atrial Enlargement in Young High-Level Endurance Athletes – Another Sign of Athlete’s Heart?

    Król Wojciech

    2016-12-01

    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.

  13. Impact of vaginal parity and aging on the architectural design of pelvic floor muscles.

    Alperin, Marianna; Cook, Mark; Tuttle, Lori J; Esparza, Mary C; Lieber, Richard L

    2016-09-01

    Vaginal delivery and aging are key risk factors for pelvic floor muscle dysfunction, which is a critical component of pelvic floor disorders. However, alterations in the pelvic floor muscle intrinsic structure that lead to muscle dysfunction because of childbirth and aging remain elusive. The purpose of this study was to determine the impact of vaginal deliveries and aging on human cadaveric pelvic floor muscle architecture, which is the strongest predictor of active muscle function. Coccygeus, iliococcygeus, and pubovisceralis were obtained from younger donors who were ≤51 years old, vaginally nulliparous (n = 5) and vaginally parous (n = 6) and older donors who were >51 years old, vaginally nulliparous (n = 6) and vaginally parous (n = 6), all of whom had no history of pelvic floor disorders. Architectural parameters, which are predictive of muscle's excursion and force-generating capacity, were determined with the use of validated methods. Intramuscular collagen content was quantified by hydroxyproline assay. Main effects of parity and aging and the interactions were determined with the use of 2-way analysis of variance, with Tukey's post-hoc testing and a significance level of .05. The mean age of younger and older donors differed by approximately 40 years (P = .001) but was similar between nulliparous and parous donors within each age group (P > .9). The median parity was 2 (range, 1-3) in younger and older vaginally parous groups (P = .7). The main impact of parity was increased fiber length in the more proximal coccygeus (P = .03) and iliococcygeus (P = .04). Aging changes manifested as decreased physiologic cross-sectional area across all pelvic floor muscles (P < .05), which substantially exceeded the age-related decline in muscle mass. The physiologic cross-sectional area was lower in younger vaginally parous, compared with younger vaginally nulliparous, pelvic floor muscles; however, the differences did not reach statistical significance

  14. Enlarging the underground hydroelectric plant at Villarino, Spain

    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.

    Kunze, S.

    1998-01-01

    To prevent damage to, or even the destruction of, components of very sensitive electrical equipment in rooms in which unsealed radioactive emitters are handled, floors must be antistatic and capable of being decontaminated. Conductive additives to the cover compounds achieve the desired leakage resistance of 5.10 4 to 10 6 Ω. Investigations have shown the decontamination capability of all floor covers and coatings to be excellent in most cases, and good in a few cases. Except for one coating, the coatings examined after radiation exposure also meet the requirements applying to nuclear installations. (orig.) [de

  17. Analytical model and application of stress distribution on mining coal floor

    ZHU Shu-yun; JIAN Zhen-quan; HOU Hong-liang; XIAO Wei-guo; YAO Pu

    2008-01-01

    Given the analysis of underground pressure, a stress calculation model of coal floor stress has been established based on a theory of elasticity. The model presents the law of stress distribution on the relatively fixed position of the mining coal floor: the extent of stress variation in a fixed floor position decreases gradually along with depth, the decreasing rate of the vertical stress is clearly larger than that of the horizontal stress at a specific depth. The direction of the maximum principal stress changes gradually from a vertical direction to a horizontal direction with the advance of the working face. The deformation and permeability of the rock mass of the coal floor are obtained by contrasting the difference of the principal stress established from theoretical calculations with curves of stress-strain and permeability-strain from tests, which is an important mechanical basis for preventing water inrush from confined aquifers.

  18. Some Passive Damping Sources on Flooring Systems besides the TMD

    Pedersen, Lars

    2010-01-01

    Impulsive loads and walking loads can generate problematic structural vibrations in flooring-systems. Measures that may be taken to mitigate the problem would often be to consider the implementation of a tuned mass damper or even more advanced vibration control technologies; this in order to add...... damping to the structure. Basically also passive humans on a floor act as a damping source, but it also turns out from doing system identification tests with a floor strip that a quite simple set-up installed on the floor (cheap and readily at hand) might do a good job in terms of reducing vertical floor...... vibrations for some floors. The paper describes the tests with the floor strip, and the results, in terms of dynamic floor behaviour, are compared with what would be expected had the floor instead been equipped with a tuned mass damper....

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

    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.

  20. [Non-neoplastic enlargement of salivary glands: clinico-histologic analysis].

    2005-01-01

    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.

  1. Comprehensive personal witness: a model to enlarge missional involvement of the local church

    Hancke, Frans

    2013-06-01

    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.

    Wu, Chen-Chi; Chen, Yuh-Shyang; Chen, Pei-Jer; Hsu, Chuan-Jen

    2005-01-01

    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.

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

    İsmail Köse

    2015-12-01

    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.

  9. Piezoelectric energy harvester under parquet floor

    Bischur, E.; Schwesinger, N.

    2011-03-01

    The design, fabrication and testing of piezoelectric energy harvesting modules for floors is described. These modules are used beneath a parquet floor to harvest the energy of people walking over it. The harvesting modules consist of monoaxial stretched PVDF-foils. Multilayer modules are built up as roller-type capacitors. The fabrication process of the harvesting modules is simple and very suitable for mass production. Due to the use of organic polymers, the modules are characterized by a great flexibility and the possibility to create them in almost any geometrical size. The energy yield was determined depending on the dynamic loading force, the thickness of piezoelectric active material, the size of the piezoelectric modules, their alignment in the walking direction and their position on the floor. An increase of the energy yield at higher loading forces and higher thicknesses of the modules was observed. It was possible to generate up to 2.1mWs of electric energy with dynamic loads of 70kg using a specific module design. Furthermore a test floor was assembled to determine the influence of the size, alignment and position of the modules on the energy yield.

  11. Enlarging the operation range of a centrifugal compressor by cutting vanes based on CFD

    Mo, J T; Pan, X H; Gu, C H; Zheng, S Y

    2013-01-01

    Many centrifugal compressors are liable to insufficient operation range. The purpose of this paper is to enlarge the operation range of a centrifugal compressor used in turbocharger by cutting vanes. Some numerical works have been done based on CFD. The comparison of the calculated and measured results shows good agreement. The overall performance characteristics of the centrifugal compressor with different cutted vanes are observed and analyzed. The performance characteristic curves show that cutting vanes can increase the operation range by more than 50% with the loss of the highest efficiency limited in 1%. The flow fields are also shown in this paper and related explanations about the change of the performance characteristics curves are given. Shock wave is also detected in the simulation, and some related characteristics are summed up

  12. Pelvic floor dyssynergia: efficacy of biofeedback training.

    2011-03-01

    Paradoxical contraction of the pelvic floor during attempts to defaecate is described as pelvic floor dyssynergia (anismus). It is a behavioural disorder (no associated morphological or neurological abnormalities); consequently, biofeedback training has been recommended as a behavioural therapy for such a disorder. The aim of the present study was to evaluate long-term satisfaction of patients diagnosed with pelvic floor dyssynergia after biofeedback. Sixty patients (35 females and 25 males) with a mean age of 30±12years and a 4year duration of constipation were included. Forty-five patients had normal colonic transit and 15 patients had slow colonic transit. History, physical examination and barium enema were done to exclude constipation secondary to organic causes. Colonic and pelvic floor functions (colon-transit time, anorectal manometry, EMG and defaecography) were performed before and after biofeedback treatments. Patients were treated on a weekly basis with an average of (6±2) sessions. At the end of sessions, 55 out of 60 patients (91.6%) reported a subjectively overall improvement. Symptoms of dyschezia were reported less frequently after biofeedback. Age and gender were not predictive factors of outcome. No symptoms at initial assessment were predictive for patient's satisfaction but the only factor of predictive value was the diagnosis of anismus and the motivated patient who wanted to continue the sessions. Biofeedback remains a morbidity free, low-cost and effective outpatient therapy for well-motivated patients complaining of functional constipation and diagnosed as pelvic floor dyssynergia.

  13. Functional imaging of the pelvic floor

    Lienemann, Andreas E-mail: andreaslienemann@web.de; Fischer, Tanja

    2003-08-01

    Introduction/Objective: Pelvic floor dysfunction and associated pelvic organ prolapse represent a major problem in our present-day society, mostly afflicting parous women. Magnetic resonance imaging (MRI) is assuming an increasingly important role in the more accurate delineation of the extent of the problem. This article briefly reviews one of the main radiological methods for the dynamic evaluation of the pelvic floor: functional cine MRI. Methods and Material: Out of the literature the smallest common denominator for functional cine MRI can be defined as follows: high field system; patient either in supine or sitting position; fast gradient echo sequence; midsagittal slice orientation; either a stack of slices or repeated measurements at the same slice position with the patient at rest or straining; image analysis using the pubococcygeal reference line. Results: All except two publications stress the usefulness of functional cine MRI in the evaluation of patients with organ descent and prolapse. This well accepted method allows for the visualization of all relevant structures in the anterior, middle and posterior compartment. It is especially useful in the detection of enteroceles, and provides a reliable postoperative follow-up tool. Isolated urinary or stool incontinence are not an indication for functional cine MRI, as is the case in patients with equivocal clinical findings. To date it does not allow for real 3D imaging of the pelvic floor or sufficient determination of fascial defects. Discussion: Functional cine MRI of the pelvic floor is a promising new imaging method for the detection of organ descent and prolapse in patients with equivocal clinical findings. The combination of function and morphology allows for an innovative view of the pelvic floor, and thus adds to our understanding of the various interactions of the structures.

  15. Predictive multiscale computational model of shoe-floor coefficient of friction.

    Moghaddam, Seyed Reza M; Acharya, Arjun; Redfern, Mark S; Beschorner, Kurt E

    2018-01-03

    Understanding the frictional interactions between the shoe and floor during walking is critical to prevention of slips and falls, particularly when contaminants are present. A multiscale finite element model of shoe-floor-contaminant friction was developed that takes into account the surface and material characteristics of the shoe and flooring in microscopic and macroscopic scales. The model calculates shoe-floor coefficient of friction (COF) in boundary lubrication regime where effects of adhesion friction and hydrodynamic pressures are negligible. The validity of model outputs was assessed by comparing model predictions to the experimental results from mechanical COF testing. The multiscale model estimates were linearly related to the experimental results (p < 0.0001). The model predicted 73% of variability in experimentally-measured shoe-floor-contaminant COF. The results demonstrate the potential of multiscale finite element modeling in aiding slip-resistant shoe and flooring design and reducing slip and fall injuries. Copyright © 2017 The Author(s).

  16. Common floor system vertical earthquake-proof structure for reactor equipment

    Morishita, Masaki.

    1996-01-01

    In an LMFBR type reactor, a reactor container, a recycling pump and a heat exchanger are disposed on a common floor. Vertical earthquake-proof devices which can be stretched only in vertical direction formed by laminating large-sized bellevilles are disposed on a concrete wall at the circumference of each of reactor equipments. A common floor is placed on all of the vertical earthquake-proof devices to support the entire earthquake-proof structure simultaneously. If each of reactor equipments is loaded on the common floor and the common floor is entirely supported against earthquakes altogether, since the movement of each of the reactor equipments loaded on the common floor is identical, relative dislocation is not exerted on the main pipelines which connect the equipments. In addition, since the entire earthquake structure has a flat common floor and each of the reactor equipments is suspended to minimize the distance between a gravitational center and a support point, locking vibration is less caused to the horizontal earthquake.

  17. A comparative study on thermal efficiency between the present floor and a ceramic floor

    Kim, Y.M.; Kim, K.S. [Korea Institute of Science and Technology, Seoul (Korea, Republic of); Choi, B.S. [Kyung Hee University, Yongin (Korea, Republic of); Ko, J.S.; Park, S.K. [Bomwoo and Co. LTD., Kwangju (Korea, Republic of)

    1999-04-01

    A ceramic floor with improved thermal conductivity and efficiency has been developed in this study. The new ceramic floor minimizes the shrinkage rate to below 0.07% and shows almost no cleavage. There is no need to repair the ceramic floor because its bottom surface is flat. It especially shows an excellent performance in the test of a compressive strength (300 kg/cm{sup 2} based on 28 days), a flexural strength (64 kg/cm{sup 2} based on 28 days), and a convenient pressing. It is lighter than the present floor and it is expected to be applicable for a self-leveling ceramic motar in the residences and apartments. It shows an excellent character in the thermal conductivity and other physical properties compare to the present cement mortar. 5 refs., 3 figs., 2 tabs.

  18. Assembly and enlargement of the primary cell wall in plants

    Cosgrove, D. J.

    1997-01-01

    Growing plant cells are shaped by an extensible wall that is a complex amalgam of cellulose microfibrils bonded noncovalently to a matrix of hemicelluloses, pectins, and structural proteins. 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.

  19. Development of floor smear sampler (floor radioactive contamination measuring instrument) for nuclear facilities

    Miyagawa, Minoru; Ito, Haruo; Nozawa, Katsuro; Shinohara, Yotaro; Hashimoto, Hiroshi.

    1980-01-01

    The control of the floor contamination with radioactive substances in nuclear facilities is strictly carried out by smear method, in which the contaminants on floor surfaces are wiped off with filter papers or cloths, and the contamination density on the floor surfaces is measured through their intensity of radioactivity. This wiping work is laborious since it is carried out in leaning-over posture when many samples must be taken in wide floor area. Therefore, to achieve labor saving in this work, an automatic sampler was developed. In the floor smear sampler developed, samples are taken on long band type wiping cloths only by handle operation, and the sample numbers are printed. When many samples are taken in wide floor area, this is especially effective, and the labor saving by 1/3 to 1/2 can be achieved. At present, this sampler is put in practical use in Hamaoka Nuclear Power Station. At the time of trial manufacture, the method of wiping, the mechanisms of wiping, cloth feeding and running, the contact pressure and the number of times of wiping affecting wiping efficiency and the required torque of a motor were examined. The developed sampler is that of constant contact pressure, vibration wiping type, and the rate of sampling is 10 sec per one sample. 100 samples can be taken on one roll of wiping cloth. The results of performance test are reported. (Kako, I.)

  20. Formaldehyde and TVOC emission behavior of laminate flooring by structure of laminate flooring and heating condition.

    An, Jae-Yoon; Kim, Sumin; Kim, Hyun-Joong

    2011-03-15

    Formaldehyde was measured with a desiccator, a 20 L chamber and the FLEC method. The formaldehyde emission rate from laminate was the highest at 32 °C using the desiccator, which then decreased with time. The formaldehyde emission using the 20 L small chamber and FLEC showed a similar tendency. There was a strong correlation between the formaldehyde and total volatile organic compounds (TVOCs) with both types of floorings using the two different methods. The formaldehyde emission rate and TVOC results were higher when tested using the FLEC method than with the 20 L small chamber method. The emission rate was affected by the joint edge length in laminate flooring. Toluene, ethylbenzene and xylene were the main VOCs emitted from laminate flooring, and there were more unidentified VOCs emitted than identified VOCs. The samples heated with a floor heating system emitted more formaldehyde than those heated using an air circulation system due to the temperature difference between the bottom panel and flooring. The TVOC emission level of the samples was higher when an air circulation system was used than when a floor heating system was used due to the high ventilation rate. Copyright © 2010 Elsevier B.V.

  3. 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.

    Nonrelaxing pelvic floor dysfunction is not widely recognized. Unlike in pelvic floor disorders caused by relaxed muscles (eg, pelvic organ prolapse or urinary incontinence, both of which often are identified readily), women affected by nonrelaxing pelvic floor dysfunction may present with a broad range of nonspecific symptoms. These may include pain and problems with defecation, urination, and sexual function, which require relaxation and coordination of pelvic floor muscles and urinary and ...

  7. Relationship between female pelvic floor dysfunction and sexual dysfunction: an observational study.

    2015-05-01

    The ability to express one's sexuality and engage in sexual activity requires multisystemic coordination involving many psychological functions as well as the integrity of the nervous, hormonal, vascular, immune, and neuromuscular body structures and functions. The purpose of this study was to investigate the associations among pelvic floor function, sexual function, and demographic and clinical characteristics in a population of women initiating physical therapy evaluation and treatment for pelvic floor-related dysfunctions (urinary incontinence, pelvic organ prolapse, vulvodynia, vaginismus, and constipation). We consented and collected completed demographic data and data related to symptoms and clinical condition on 85 consecutive patients in an outpatient physical therapy clinic. Clinical and anthropometric characteristics were analyzed descriptively. Analysis of variance and linear regression analyses were used to analyze Female Sexual Function Index (FSFI) scale ratings, whereas zero-inflated beta-binomial regression was applied to the pain subscale. Main outcome measure was FSFI score, whereas the secondary outcome measure was the FSFI subscale score related to pain. Women in our sample were 38 years old on average, 33% of whom had given birth and 82% of whom had high tone pelvic floor. Being in the middle-tercile age group and exhibiting low pelvic floor tone (Beta = 6.8; 95% confidence interval [CI] = [1.4; 12.0]) were significantly associated with lower levels of sexual dysfunction. Women with low tone pelvic floor also reported lower pain (odds ratio = 4.0; 95% CI = [1.6; 9.6]), whereas younger aged and physically unsatisfied subjects were more likely not to have sexual activity in the month prior to scale measurement. In female patients with pelvic floor muscle dysfunction undergoing physical therapy and rehabilitation, sexual dysfunction appears to be significantly correlated with age and high pelvic floor muscle tone. © 2015

  14. Lysosomal enlargement and lysosomal membrane destabilisation in mussel digestive cells measured by an integrative index

    Izagirre, Urtzi; Marigomez, Ionan

    2009-01-01

    Lysosomal responses (enlargement and membrane destabilisation) in mussel digestive cells are well-known environmental stress biomarkers in pollution effects monitoring in marine ecosystems. Presently, in laboratory and field studies, both responses were measured separately (in terms of lysosomal volume density - Vv - and labilisation period -LP) and combined (lysosomal response index - LRI) in order to contribute to their understanding and to develop an index useful for decisions makers. LRI integrates Vv and LP, which are not necessarily dependent lysosomal responses. It is unbiased and more sensitive than Vv and LP alone and diminishes background due to confounding factors. LRI provides a simple numerical index (consensus reference = 0; critical threshold = 1) directly related to the pollution impact degree. Moreover, LRI can be represented in a way that allows the interpretation of lysosomal responses, which is useful for environmental scientists. - Lysosomal responses to pollutants measured by an integrative index.

  15. Development of remote operated floor contamination monitor

    Sreekumar, K.; Gangamohan, M.; Kannan, R.K.; Rajan, S.

    2005-01-01

    Contamination check of floors and walkways in and around Reactor building areas forms an integral part of Radiation Protection Program in Power Stations. Though random swipe check method is adopted for the detection of loose contamination, this method has the disadvantage of leaving the fixed contamination and hotspots undetected. Hence, scanning the area with a sensitive detector, held close to the surface provides positive means for the detection of contamination. Checking large areas and walkways by holding the detector close to the surface involves physical work. Also, areas which are unapproachable due to congestion of equipment, may go uncovered by contamination monitoring in order to eliminate the physical strain involved in such contamination monitoring and to cover unapproachable areas, a small size prototype device that can be operated remotely was fabricated. This device detects contamination instantaneously and accurately. This paper describes design and fabrication of the device used for floor contamination monitoring. (author)

  16. RFID Data Cleaning for Shop Floor Applications

    Ziekow, Holger; Ivantysynova, Lenka; Günter, Oliver

    In several case studies we found that shop-floor applications in manufacturing pose special challenges to cleaning RFID data. The underlying problem in many scenarios is the uncertainty about the exact location of observed RFID tags. Simple filter s provided in common middleware solutions do not cope well with these challenges. Therefore we have developed an approach based on maximum-likelihood estimation to infer a tag's location within the reader range. This enables improved RFID data cleaning in a number of application scenarios. We stress the benefits of our approach along exemplary application scenarios that we found in manufacturing. In simulations and experiments with real world data we show that our approach outperforms existing solutions. Our approach can extend RFID middleware or reader firmware, to improve the use of RFID in a range of shop-floor applications.

  17. Internal nasal floor configuration in Homo with special reference to the evolution of Neandertal facial form.

    Franciscus, Robert G

    2003-06-01

    The presence of a steeply sloping or depressed nasal floor within the nasal cavity of Neandertals is frequently mentioned as a likely specialization or autapomorphy. The depressed nasal floor has also been seen as contributing to a relatively more capacious nasal cavity in Neandertals, which is tied to cold-climate respiratory adaptation and energetics. These observations have been limited largely to a relatively few intact crania, and the character states associated with this trait have not been as precisely codified or analyzed as those published for Plio-Pleistocene hominins (McCollum et al., 1993, J. Hum. Evol. 24, 87; McCollum, 2000, Am. J. Phys. Anthrop. 112, 275). This study examines the internal nasal floor topography in complete crania and isolated maxillae in European, west Asian, and African fossil Homo (n=158) including 25 Neandertals, and a wide range of recent humans from Europe, the Near East, and Africa (n=522). The configuration of the internal nasal floor relative to the nasal cavity entrance is codified as: 1) level, forming a smooth continuous plane; 2) sloped or mildly stepped; or 3) bilevel with a pronounced vertical depression. The frequency of these nasal floor configurations, and their relationship to both nasal margin cresting patterning and a comprehensive set of nasofacial metrics is examined. Neandertals show a high frequency of the bilevel (depressed) configuration in both adults and subadults (80%), but this configuration is also present in lower frequencies in Middle Pleistocene African, Late Pleistocene non-Neandertal (Skhul, Qafzeh), and European Later Upper Paleolithic samples (15%-50%). The bilevel configuration is also present in lower frequencies (ca. 10%) in all recent human samples, but attains nearly 20% in some sub-Saharan African samples. Across extinct and extant Homo (excluding Neandertals), internal nasal floor configuration is not associated with piriform aperture nasal margin patterning, but the two are strongly

  18. Polypropylene Darning: A New Alternative for Reconstruction of Orbital Floor after Total Maxillectomy.

    Sharma, Prashant

    2015-06-01

    Removal of orbital floor is an integral part of total (radical) maxillectomy (type IIIa), which if not managed properly, may lead to some eye related distressing complications like diplopia, eyelid malposition, epiphora, dacryocystitis, enopthalmos and ectoprion. Among all, diplopia is the most distressing complication which hampers daily activity. Various options for orbital floor reconstruction are available like titanium sheet, polypropylene mesh, non-vascularized or vascularized bone graft, pedicled flaps, micro-vascular free flaps, prosthesis placement, and split skin graft followed by obturator placement. Till date no-body has tried stabilization of eye ball by 'darning' the orbital floor using non-absorbable suture. 'Polypropylene suture darning' is an easy to learn, novel method with equally good results. Five patients with potentially resectable tumors underwent total maxillectomy. I used polypropylene 3-0 round body suture and 'darning' was done at orbital floor, incorporating periosteum (if remaining) and peri-orbital fat into the sutures. Muscle flaps were done to provide bulk and palatal reconstruction. Assessment of patients was done post-operatively at day-5 i.e., before discharge and at 1 month after surgery, and also in further follow up visits. The results were very good in terms of clear vision & eye movements (directly related to 'darning'), and the aesthetic look of patients and bilateral symmetry were satisfactory (not related to darning). Darning of orbital floor by polypropylene after total maxillectomy is an easy to learn and cost-effective method of reconstruction with good results.

    A system for mounting a set of wave energy converters in the ocean includes a pole attached to a floor of an ocean and a slider mounted on the pole in a manner that permits the slider to move vertically along the pole and rotate about the pole. The wave energy converters can then be mounted on the slider to allow adjustment of the depth and orientation of the wave energy converters.

  20. Understanding gaming floor influences on player behaviour

    Griffiths, MD

    2009-01-01

    Efforts to entice and retain player activity within a casino gaming environment require bringing to bear a range of sensory and physical influences. The challenge is to accomplish the operators’ objectives while at the same time ensuring any potential negative effects on the player are minimised. How casinos keep this in balance is at the heart of how the gaming floor works, and assessing such matters is becoming a necessary part of social responsibility.

  1. Vestibular Dysfunction in Patients with Enlarged Vestibular Aqueduct.

    Zalewski, Chris K; Chien, Wade W; King, Kelly A; Muskett, Julie A; Baron, Rachel E; Butman, John A; Griffith, Andrew J; Brewer, Carmen C

    2015-08-01

    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.

    2017-10-01

    In this study, we aimed to assess the effect of the duration of fixed orthodontic treatment on gingival enlargement (GE) in adolescents and young adults. The sample consisted of 260 subjects (ages, 10-30 years) divided into 4 groups: patients with no fixed orthodontic appliances (G0) and patients undergoing orthodontic treatment for 1 year (G1), 2 years (G2), or 3 years (G3). Participants completed a structured questionnaire on sociodemographic characteristics and oral hygiene habits. Clinical examinations were conducted by a calibrated examiner and included the plaque index, the gingival index, and the Seymour index. Poisson regression models were used to assess the association between group and GE. We observed increasing means of plaque, gingivitis, and GE in G0, G1, and G2. No significant differences were observed between G2 and G3. Adjusted Poisson regression analysis showed that patients undergoing orthodontic treatment had a 20 to 28-fold increased risk for GE than did those without orthodontic appliances (G1, rate ratio [RR] = 20.2, 95% CI = 9.0-45.3; G2, RR = 27.0, 95% CI = 12.1-60.3; G3 = 28.1; 95% CI = 12.6-62.5). The duration of orthodontic treatment significantly influenced the occurrence of GE. Oral hygiene instructions and motivational activities should target adolescents and young adults undergoing orthodontic treatment. Copyright © 2017 American Association of Orthodontists.

    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.)

  6. Body-enlarging effect of royal jelly in a non-holometabolous insect species, Gryllus bimaculatus

    Atsushi Miyashita

    2016-06-01

    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.

    Orbital floor fractures of varying sizes commonly occur after orbital injuries and remain a serious challenge. Serious complications of such fractures include enopthalmos, restriction of extraocular movement, and diplopia. There is a dearth of literature that can be applied widely, easily, and successfully in all such situations, and therefore there is no consensus on the treatment protocol of this pathology yet. Autogenous grafts and alloplastic and allogenic materials with a wide variety of advantages and disadvantages have been discussed. The value of preoperative and postoperative ophthalmological examination should be standard of care in all orbital fracture patients. An ideal reconstructed orbital floor fracture should accelerate the restoration of orbital function with acceptable cosmetic results. Management parameters of orbital fractures such as timing of surgery, incision type, and implant materials, though widely discussed, remain controversial. In this study, 55 patients with orbital floor fractures surgically reconstructed with conchal cartilage grafts between 2008 and 2014 were retrospectively evaluated. Complications and long-time follow-up visit results have been reported with clinical and radiographic findings. The aim of this study was to present the authors' clinical experiences of reconstruction of blow-out fractures with auricular conchal graft and to evaluate the other materials available for use.

  8. A comparison of floor response spectra techniques

    Yan, M.J.; Galford, J.E.

    1983-01-01

    Floor response spectra (FRS) conventionally have been generated using a time-history method. Babcock and Wilcox has developed a new technique, the Fast Floor Response Spectra (FFRS) method, in which dynamic analyses are done entirely in the frequency domain. This paper compares the two techniques and demonstrates that the FFRS method complies with the 'equivalency' and 'conservatism' requirements of the US NRC's Standard Review Plan. The upper end of a once-through steam generator in the B and W 205 nuclear steam supply system (NSSS) was used to demonstrate that the FFRS method is equivalent to the time-history technique. The two techniques were compared with respect to frequency content and magnitude of response for a given point on the structure. First, the specified forcing function was described in terms of an acceleration time history and an acceleration spectra enveloping that time history. The time-history forcing function was then used in a direct transient analysis to determine the response at the specified point on the NSSS. The resultant response was subsequently converted to a floor response spectra for that point. To show that the FFRS method gave equivalent and conservative results, the FFRS technique was used to determine the modal response directly from the spectral description of the forcing function. The FFRS- and time-history-generated data agreed to within 13 (worst case on conservative side) of each other with the former cutting analytical costs by 99%. (orig./HP)

  9. Mechanical decontamination techniques for floor drain systems

    Palau, G.L.

    1987-01-01

    The unprecedented nature of cleanup activities at Three Mile Island Unit 2 (TMI-2) following the 1979 accident has necessitated the development of new techniques to deal with radiation and contamination in the plant. One of these problems was decontamination of floor drain systems, which had become highly contaminated with various forms of dirt and sludge containing high levels of fission products and fuel from the damaged reactor core. The bulk of this contamination is loosely adherent to the drain pipe walls; however, significant amounts of contamination have become incorporated into pipe wall oxide and corrosion layers and embedded in microscopic pits and fissures in the pipe wall material. The need to remove this contamination was recognized early in the TMI-2 cleanup effort. A program consisting of development and laboratory testing of floor drain decontamination techniques was undertaken early in the cleanup with support from the Electric Power Research Institute (EPRI). Based on this initial research, two techniques were judged to show promise for use at TMI-2: a rotating brush hone system and a high-pressure water mole nozzle system. Actual use of these devices to clean floor drains at TMI-2 has yielded mixed decontamination results. The decontamination effectiveness that has been obtained is highly dependent on the nature of the contamination in the drain pipe and the combination of decontamination techniques used

  10. Lead exposures from varnished floor refinishing.

    Schirmer, Joseph; Havlena, Jeff; Jacobs, David E; Dixon, Sherry; Ikens, Robert

    2012-01-01

    We evaluated the presence of lead in varnish and factors predicting lead exposure from floor refinishing and inexpensive dust suppression control methods. Lead in varnish, settled dust, and air were measured using XRF, laboratory analysis of scrape and wipe samples, and National Institute for Occupational Safety and Health (NIOSH) Method 7300, respectively, during refinishing (n = 35 homes). Data were analyzed using step-wise logistic regression. Compared with federal standards, no lead in varnish samples exceeded 1.0 mg/cm(2), but 52% exceeded 5000 ppm and 70% of settled dust samples after refinishing exceeded 40 μg/ft(2). Refinishing pre-1930 dwellings or stairs predicted high lead dust on floors. Laboratory analysis of lead in varnish was significantly correlated with airborne lead (r = 0.23, p = 0.014). Adding dust collection bags into drum sanders and HEPA vacuums to edgers and buffers reduced mean floor lead dust by 8293 μg Pb/ft(2) (pairborne lead exposures to less than 50 μg/m(3). Refinishing varnished surfaces in older housing produces high but controllable lead exposures.

  11. Achondroplasia in children: correlation of ventriculomegaly, size of foramen magnum and jugular foramina, and emissary vein enlargement.

    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.

  12. Study of peak broadening effect in floor time histories

    Soni, R.S.; Kushwaha, H.S.; Mahajan, S.C.; Kakodkar, A.

    1996-01-01

    Seismic design of secondary systems such components and piping is usually carried out by using the floor motions at their support points. These floor motions can be in the form of Floor Response Spectra (FRS) or the Floor Time Histories (FTH). In order to account for the various uncertainties in generating these floor motions, these motions should be peak broadened and smoothened as per the regulatory codes. Presented here in this paper is the methodology to account for such peak broadening effect in the FTH. Results of this study have been compared with the FRS approach and various important conclusions have been arrived at based on the study

  14. The influence of flooring on environmental stressors: a study of three flooring materials in a hospital.

    Harris, Debra D

    2015-01-01

    Three flooring materials, terrazzo, rubber, and carpet tile, in patient unit corridors were compared for absorption of sound, comfort, light reflectance, employee perceptions and preferences, and patient satisfaction. Environmental stressors, such as noise and ergonomic factors, effect healthcare workers and patients, contributing to increased fatigue, anxiety and stress, decreased productivity, and patient safety and satisfaction. A longitudinal comparative cohort study comparing three types of flooring assessed sound levels, healthcare worker responses, and patient Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) ratings over 42 weeks. A linear mixed model analysis was conducted to determine significant differences between the means for participant responses and objective sound meter data during all three phases of the study. A significant difference was found for sound levels between flooring type for equivalent continuous sound levels. Carpet tile performed better for sound attenuation by absorption, reducing sound levels 3.14 dBA. Preferences for flooring materials changed over the course of the study. The HCAHPS ratings aligned with the sound meter data showing that patients perceived the noise levels to be lower with carpet tiles, improving patient satisfaction ratings. Perceptions for healthcare staff and patients were aligned with the sound meter data. Carpet tile provides sound absorption that affects sound levels and influences occupant's perceptions of environmental factors that contribute to the quality of the indoor environment. Flooring that provides comfort underfoot, easy cleanability, and sound absorption influence healthcare worker job satisfaction and patient satisfaction with their patient experience. © The Author(s) 2015.

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

    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.

    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.

  19. Sea-floor geology in northwestern Block Island Sound, Rhode Island

    McMullen, Katherine Y.; Poppe, Lawrence J.; Ackerman, Seth D.; Blackwood, Dann S.; Woods, D.A.

    2014-01-01

    Multibeam-echosounder and sidescan-sonar data, collected by the National Oceanic and Atmospheric Administration in a 69-square-kilometer area of northwestern Block Island Sound, are used with sediment samples, and still and video photography of the sea floor, collected by the U.S. Geological Survey at 43 stations within this area, to interpret the sea-floor features and sedimentary environments. Features on the sea floor include boulders, sand waves, scour depressions, modern marine sediments, and trawl marks. Boulders, which are often several meters wide, are found in patches in the shallower depths and tend to be overgrown with sessile flora and fauna. They are lag deposits of winnowed glacial drift, and reflect high-energy environments characterized by processes associated with erosion and nondeposition. Sand waves and megaripples tend to have crests that either trend parallel to shore with 20- to 50-meter (m) wavelengths or trend perpendicular to shore with several-hundred-meter wavelengths. The sand waves reflect sediment transport directions perpendicular to shore by waves, and parallel to shore by tidal or wind-driven currents, respectively. Scour depressions, which are about 0.5 m lower than the surrounding sea floor, have floors of gravel and coarser sand than bounding modern marine sediments. These scour depressions, which are conspicuous in the sidescan-sonar data because of their more highly reflective coarser sediment floors, are likely formed by storm-generated, seaward-flowing currents and maintained by the turbulence in bottom currents caused by their coarse sediments. Areas of the sea floor with modern marine sediments tend to be relatively flat to current-rippled and sandy.

  20. Investigation of Floor Surface Finishes for Optimal Slip Resistance Performance

    2018-03-01

    Full Text Available Background: Increasing the slip resistance of floor surfaces would be desirable, but there is a lack of evidence on whether traction properties are linearly correlated with the topographic features of the floor surfaces or what scales of surface roughness are required to effectively control the slipperiness of floors. Objective: This study expands on earlier findings on the effects of floor surface finishes against slip resistance performance and determines the operative ranges of floor surface roughness for optimal slip resistance controls under different risk levels of walking environments. Methods: Dynamic friction tests were conducted among three shoes and nine floor specimens under wet and oily environments and compared with a soapy environment. Results: The test results showed the significant effects of floor surface roughness on slip resistance performance against all the lubricated environments. Compared with the floor-type effect, the shoe-type effect on slip resistance performance was insignificant against the highly polluted environments. The study outcomes also indicated that the oily environment required rougher surface finishes than the wet and soapy ones in their lower boundary ranges of floor surface roughness. Conclusion: The results of this study with previous findings confirm that floor surface finishes require different levels of surface coarseness for different types of environmental conditions to effectively manage slippery walking environments. Collected data on operative ranges of floor surface roughness seem to be a valuable tool to develop practical design information and standards for floor surface finishes to efficiently prevent pedestrian fall incidents. Keywords: floor surface finishes, operational levels of floor surface roughness, slip resistance, wet, soapy and oily environments

    2002-01-01

    The paper presents an analysis of the future of nuclear energy at the European level taking into account the main factors which influence its development among which the most important are: - enlargement of EU to 30 member states with different energy structure; - the increase of energy consumption; - the constant increasing of external dependence for energy which is estimated at 70% in the next 20-30 years; - liberalisation of the energy sources and supply sector; - environmental concerns, including climate change. In the Green Paper, nuclear is grouped together with coal, oil, gas and renewables as 'less than perfect' energy options and together with coal it is classed as an 'undesirable' and referred to as a 'source of energy in doubt ' which is ' tainted by the original sin of dual usage (civil and military) in the fuel cycle'. The final conclusion is 'the future of nuclear energy in Europe is uncertain'. It depends on several factors beyond energy demand; including: a solution to the problems of managing nuclear waste, the economic viability of the new generation of power stations, the safety of reactors in Eastern Europe, in particular applicant countries and policies to combat global warming. The 'essential questions' for nuclear is 'How can the community develop fusion technology and reactors for the future, reinforce nuclear safety and find a solution to the problem of nuclear waste?' There are a number of very important factors that will influence the future of nuclear energy inside the European Union. The first and foremost of these is continuing the safe operation of the existing nuclear facilities. The second is the demand for energy, in particular electricity. The third is the nuclear sector's ability to meet a share of this demand in a competitive way. If the demand materialises, there are likely to be reactors available that can further improve nuclear competitiveness while maintaining its recent excellent safety record. It will be the market that

  2. Comparison between dynamic cystocolpoproctography and dynamic pelvic floor MRI: pros and cons: which is the "functional" examination for anorectal and pelvic floor dysfunction?

    Maglinte, Dean D T; Hale, Douglass S; Sandrasegaran, Kumar

    2013-10-01

    "Functional" imaging of anorectal and pelvic floor dysfunction has assumed an important role in the diagnosis and management of these disorders. Although defecography has been widely practiced for decades to evaluate the dynamics of rectal emptying, debate concerning its clinical relevance, how it should be done and interpreted continues. Due to the recognition of the association of defecatory disorders with pelvic organ prolapse in women, the need to evaluate the pelvic floor as a unit has arisen. To meet this need, defecography has been extended to include not only evaluation of defecation disorders but also the rest of the pelvic floor by opacifying the small bowel, vagina, and the urinary bladder. The term "dynamic cystocolpoproctography" (DCP) has been appropriately applied to this examination. Rectal emptying performed with DCP provides the maximum stress to the pelvic floor resulting in complete levator ani relaxation. In addition to diagnosing defecatory disorders, this method of examination demonstrates maximum pelvic organ descent and provides organ-specific quantification of organ prolapse, information that is only inferred by means of physical examination. It has been found to be of clinical value in patients with defecation disorders and the diagnosis of associated prolapse in other compartments that are frequently unrecognized by history taking and the limitations of physical examination. Pelvic floor anatomy is complex and DCP does not show the anatomical details pelvic magnetic resonance imaging (MRI) provides. Technical advances allowing acquisition of dynamic rapid MRI sequences has been applied to pelvic floor imaging. Early reports have shown that pelvic MRI may be a useful tool in pre-operative planning of these disorders and may lead to a change in surgical therapy. Predictions of hypothetical increase cancer incidence and deaths in patients exposed to radiation, the emergence of pelvic floor MRI in addition to questions relating to the

    In recent years, there is an increased in floor vibration problems of structures like residential and commercial building. Vibration is defined as a serviceability issue related to the comfort of the occupant or damage equipment. Human activities are the main source of vibration in the building and it could affect the human comfort and annoyance of residents in the building when the vibration exceed the recommend level. A new building, Madrasah Tahfiz located at Yong Peng have vibration problem when load subjected on the first floor of the building. However, the limitation of vibration occurs on building is unknown. Therefore, testing is needed to determine the vibration behaviour (frequency, damping ratio and mode shape) of the building. Heel-drop with pace 2Hz was used in field measurement to obtain the vibration response. Since, the heel-drop test results would vary in light of person performance, test are carried out three time to reduce uncertainty. Natural frequency from Frequency Response Function analysis (FRF) is 17.4Hz, 16.8, 17.4Hz respectively for each test.

  4. A Mobile Automated Characterization System (MACS) for indoor floor characterization

    Richardson, B.S.; Haley, D.C.; Dudar, A.M.; Ward, C.R.

    1995-01-01

    The Savannah River Technology Center (SRTC) and Oak Ridge National Laboratory are developing an advanced Mobile Automated Characterization System (MACS) to characterize indoor contaminated floors. MACS is based upon Semi-Intelligent Mobile Observing Navigator (SIMON), an earlier floor characterization system developed at SRTC. MACS will feature enhanced navigation systems, operator interface, and an interface to simplify integration of additional sensors. The enhanced navigation system will provide the capability to survey large open areas much more accurately than is now possible with SIMON, which is better suited for hallways and corridors that provide the means for recalibrating position and heading. MACS operator interface is designed to facilitate MACS's use as a tool for health physicists, thus eliminating the need for additional training in the robot's control language. Initial implementation of MACS will use radiation detectors. Additional sensors, such as PCB sensors currently being developed, will be integrated on MACS in the future. Initial use of MACS will be focused toward obtaining comparative results with manual methods. Surveys will be conducted both manually and with MACS to compare relative costs and data quality. While clear cost benefits anticipated, data quality benefits should be even more significant

  5. Analysis of the Harmfulness of Water-Inrush from Coal Seam Floor Based on Seepage Instability Theory

    2007-01-01

    A theory of seepage instability was used to estimate the harmfulness of water-inrush from a coal seam floor in a particular coal mine of the Mining Group, Xuzhou.Based on the stratum column chart in this coal mine, the distribution of stress in mining floors when the long-wall mining was respectively pushed along to 100 m and to 150 m was simulated by using the numerical software (RFPA2D).The permeability parameters of the coal seam floor are described given the relationship between permeability parameters.Strain and the water-inrush-indices were calculated.The water-inrush-index was 67.2% when the working face was pushed to 100 m, showing that water-inrush is possible and it was 1630% when the working face was pushed to 150 m, showing that water-inrush is quite probable.The results show that as long-wall mining is pushed along, the failure zone is enlarged, the strain increased, and fissures developed correspondingly, resulting in the formation of water-inrush channels.Accompanied by the failure of the strata, the permeability increased exponentially.In contrast, the non-Darcy flow β factor and the acceleration coefficient decreased exponentially, while the increase in the water-inrush-index was nearly exponential and the harmfulness of water-inrush in the coal mine increased accordingly.

  6. Deflection of resilient materials for reduction of floor impact sound.

    Lee, Jung-Yoon; Kim, Jong-Mun

    2014-01-01

    Recently, many residents living in apartment buildings in Korea have been bothered by noise coming from the houses above. In order to reduce noise pollution, communities are increasingly imposing bylaws, including the limitation of floor impact sound, minimum thickness of floors, and floor soundproofing solutions. This research effort focused specifically on the deflection of resilient materials in the floor sound insulation systems of apartment houses. The experimental program involved conducting twenty-seven material tests and ten sound insulation floating concrete floor specimens. Two main parameters were considered in the experimental investigation: the seven types of resilient materials and the location of the loading point. The structural behavior of sound insulation floor floating was predicted using the Winkler method. The experimental and analytical results indicated that the cracking strength of the floating concrete floor significantly increased with increasing the tangent modulus of resilient material. The deflection of the floating concrete floor loaded at the side of the specimen was much greater than that of the floating concrete floor loaded at the center of the specimen. The Winkler model considering the effect of modulus of resilient materials was able to accurately predict the cracking strength of the floating concrete floor.

  7. Surgical reconstruction of pelvic floor descent: anatomic and functional aspects.

    Wagenlehner, F M E; Bschleipfer, T; Liedl, B; Gunnemann, A; Petros, P; Weidner, W

    2010-01-01

    The human pelvic floor is a complex structure and pelvic floor dysfunction is seen frequently in females. This review focuses on the surgical reconstruction of the pelvic floor employing recent findings on functional anatomy. A selective literature research was performed by the authors. Pelvic floor activity is regulated by 3 main muscular forces that are responsible for vaginal tension and suspension of the pelvic floor organs, bladder and rectum. A variety of symptoms can derive from pelvic floor dysfunctions, such as urinary urge and stress incontinence, abnormal bladder emptying, fecal incontinence, obstructive bowel disease syndrome and pelvic pain. These symptoms mainly derive, for different reasons, from laxity in the vagina or its supporting ligaments as a result of altered connective tissue. Pelvic floor reconstruction is nowadays driven by the concept that in case of pelvic floor symptoms, restoration of the anatomy will translate into restoration of the physiology and ultimately improve patients' symptoms. The surgical reconstruction of the anatomy is almost exclusively focused on the restoration of the lax pelvic floor ligaments. Exact preoperative identification of the anatomical lesions is necessary to allow for exact anatomical reconstruction with respect to the muscular forces of the pelvic floor. Copyright 2010 S.

  8. Methods and Principles of Determining the Footwear and Floor Tribological Characteristics

    D. Stamenković

    2017-09-01

    Full Text Available There are many standards relating to the anti-slip properties of footwear and flooring. These standards describe the different test methods and procedures for determining the footwear and floor slip resistance in different conditions. In this paper authors systematize the standards in this field applied in the EU and in Serbia and cite the Serbian institutes which are certified for this type of testing. In addition, the authors have carried out an analysis and comparison of the tests that are defined in these standards, indicating their advantages and disadvantages. Importance of the static and kinetic friction testing in determining the anti-slip properties of footwear and flooring is specifically indicated. Considering the current standards in area of slip resistance of the footwear and floor covering authors have determined the testing conditions for laboratory measuring the friction forces of different floor and footwear materials. The laboratory measurement has carried out at Faculty of Mechanical Engineering in Niš. The measuring results and their analysis are presented in the paper, as well.

  9. Study on emission of decomposed chemicals of esters contained in PVC flooring and adhesive

    2-Ethyl-1-hexanol (2E1H) is sometimes detected in indoor air at relatively high concentrations. The emission mechanism for 2E1H is considered to be that moisture with a high pH in concrete slabs and self-leveling sub-flooring material reacts with di-2-ethylhexyl phthalate (DEHP) in the polyvinyl chloride (PVC) flooring and compounds containing the 2-ethyl-1-hexyl group in the adhesive. 2E1H is considered to be one of the causes of odor in indoor air and sick building syndrome, so it is important to clarify the 2E1H emission mechanism for IAQ. However, there are few reports on any experimentation into 2E1H emission by chemical reaction involving building materials. In this study, PVC floorings are attached using various adhesives to a self-leveling sub-flooring material that contains water, and their 2E1H emission rates are measured. Furthermore, the components of the adhesives are determined using chemical analysis. It is found that 2E1H emission rates from the floor are affected by the type of adhesive used. On the other hand, some components in the adhesives may suppress the hydrolysis of esters. The hydrolysis of polymers and residual monomers in the adhesive causes 2E1H emission from the adhesive.

  10. Physical activity and the pelvic floor.

    Nygaard, Ingrid E; Shaw, Janet M

    2016-02-01

    Pelvic floor disorders are common, with 1 in 4 US women reporting moderate to severe symptoms of urinary incontinence, pelvic organ prolapse, or fecal incontinence. Given the high societal burden of these disorders, identifying potentially modifiable risk factors is crucial. Physical activity is one such potentially modifiable risk factor; the large number of girls and women participating in sport and strenuous training regimens increases the need to understand associated risks and benefits of these exposures. The aim of this review was to summarize studies reporting the association between physical activity and pelvic floor disorders. Most studies are cross-sectional and most include small numbers of participants. The primary findings of this review include that urinary incontinence during exercise is common and is more prevalent in women during high-impact sports. Mild to moderate physical activity, such as brisk walking, decreases both the odds of having and the risk of developing urinary incontinence. In older women, mild to moderate activity also decreases the odds of having fecal incontinence; however, young women participating in high-intensity activity are more likely to report anal incontinence than less active women. Scant data suggest that in middle-aged women, lifetime physical activity increases the odds of stress urinary incontinence slightly and does not increase the odds of pelvic organ prolapse. Women undergoing surgery for pelvic organ prolapse are more likely to report a history of heavy work than controls; however, women recruited from the community with pelvic organ prolapse on examination report similar lifetime levels of strenuous activity as women without this examination finding. Data are insufficient to determine whether strenuous activity while young predisposes to pelvic floor disorders later in life. The existing literature suggests that most physical activity does not harm the pelvic floor and does provide numerous health benefits for

    Lipomas are benign soft tissue tumours composed mainly of mature adipose tissue. Histological variants of lipomas have been named according to the type of tissue present and they include fibrolipoma, angiolipoma, osteolipoma, chondrolipoma and others. Osteolipoma, a classic lipoma with osseous metaplasia, is a very rare histological variant. Owing to the rarity of oral osteolipomas, we report an uncommon case of osteolipoma located on the floor of the mouth of a 20-year-old female patient and include a review of the literature. 2015 BMJ Publishing Group Ltd.

  13. Shop Floor-Level Control of Manufacturing Companies: An Interview Study in Finland

    Tokola Henri

    2015-02-01

    Full Text Available This paper publishes the results of interviews regarding shop-floor-level control of 18 Finnish manufacturing companies. The interviews had 17 open questions relating to demand characteristics, shop floor-level control issues, production flexibility, inventory control, and potential development areas. In order to get insights from the interviews, this paper analyses the answers from the interviews and categorises them into typical answers. The companies that were interviewed are also categorised as small companies with their own end products, subcontractors, or large companies with their own end products, and the emphasis of the analysis is on how companies differ in their shop floor-level control. The results show that different types of companies have different characteristics. Small companies are characterised by constant workflow, seasonal trends in demand, and the use of forecasts. Subcontractors have great daily variation in their demand and processing times. Large companies tend to focus on inventory issues.

    The study aimed to investigate sacral peripheral nerve function and continuity of pudendal nerve in patients with chronic spinal cord injury (SCI) using pelvic floor electrophysiological tests. Twelve patients with low cervical or thoracic SCI were prospectively included. Quantitative external anal sphincter (EAS) muscle electromyography (EMG), pudendal nerve terminal motor latency (PNTML) testing, bulbocavernosus reflex (BCR) testing and pudendal short-latency somatosensory-evoked potential (SEP) measurement were performed. In EAS muscle EMG, two patients had abnormal increased spontaneous activity and seven prolonged motor unit potential duration. PNTML was normal in 10 patients. BCR was present with normal latency in 11 patients and with prolonged latency in one. The second component of BCR could be recorded in four patients. SEPs showed absent cortical responses in 11 patients and normal latency in one. Pudendal nerve and sacral lower motor neuron involvement are significantly associated with chronic SCI, most prominently in EAS muscle EMG. The frequent finding of normal PNTML latencies supports earlier concerns on the utility of this test; however, BCR and pudendal SEPs may have clinical relevance. As intact peripheral nerves including pudendal nerve are essential for efficient supportive therapies, pelvic floor electrophysiological testing prior to these interventions is highly recommended.

    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.

    2018-01-01

    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.

  8. Gait of dairy cows on floors with different slipperiness.

    Telezhenko, E; Magnusson, M; Bergsten, C

    2017-08-01

    This study assessed the slip resistance of different types of solid flooring in cattle housing using a range of technical tests and gait analysis. Dynamic and static coefficient of friction, skid resistance, and abrasiveness were tested on concrete flooring with a smooth finish, a grooved pattern, or a tamped pattern, acid-resistant mastic asphalt, soft rubber mats, and a worn slatted concrete floor. Coefficients of friction and skid resistance were tested under clean and slurry-soiled conditions. Linear kinematic variables were assessed in 40 cows with trackway measurements after the cows passed over the floors in a straight walk. All gait variables were assessed as deviations from those obtained on the slatted concrete floor, which was used as a baseline. The coefficient of friction tests divided the floors into 3 categories: concrete flooring, which had a low coefficient of friction (0.29-0.41); mastic asphalt flooring, which had medium values (0.38-0.45); and rubber mats, which had high values (0.49-0.57). The highest abrasion (g/10 m) was on the asphalt flooring (4.48), and the concrete flooring with a tamped pattern had significantly higher abrasiveness (2.77) than the other concrete floors (1.26-1.60). Lowest values on the skid-resistance tests (dry/wet) were for smooth concrete (79/35) and mastic asphalt (65/47), especially with a slurry layer on the surface. Gait analysis mainly differentiated floors with higher friction and abrasion by longer strides and better tracking. Step asymmetry was lower on floors with high skid-resistance values. The most secure cow gait, in almost every aspect, was observed on soft rubber mats. Relationships between gait variables and physical floor characteristics ranged from average to weak (partial correlations 0.54-0.16). Thus, none of the physical characteristics alone was informative enough to characterize slip resistance. With reference to gait analysis, the abrasiveness of the hard surfaces was more informative than the

  9. Obtaining and Estimating Low Noise Floors in Vibration Sensors

    Brincker, Rune; Larsen, Jesper Abildgaard

    2007-01-01

    For some applications like seismic applications and measuring ambient vibrations in structures, it is essential that the noise floors of the sensors and other system components are low and known to the user. Some of the most important noise sources are reviewed and it is discussed how the sensor...... can be designed in order to obtain a low noise floor. Techniques to estimate the noise floors for sensors are reviewed and are demonstrated on a commercial commonly used sensor for vibration testing. It is illustrated how the noise floor can be calculated using the coherence between simultaneous...

    Highlights: • High resolution computed tomography (HRCT) findings of airspace enlargement with fibrosis (AEF), recently identified as a smoking related change. • Investigation was in 35 smokers. • They underwent lobectomy for lung cancer with pathological confirmation of AEF. • Multiple, thin-walled cysts are one of the HRCT features of AEF. - Abstract: Purpose: Airspace enlargement with fibrosis (AEF) has been identified pathologically as a smoking related change. We sought to identify the HRCT findings of AEF and search for distinguishing features from honeycombing. Materials and methods: 50 patients (47 males; mean age 69) were evaluated. All had undergone lobectomy for lung cancer and had confirmed AEF and/or usual interstitial pneumonia (UIP) by pathological evaluation. HRCT findings were first evaluated preresection for resected lobes, and then correlated with the subsequent pathological findings in the resection specimens. Three groups were devised: one with AEF alone to determine the HRCT findings of AEF, a second with AEF and UIP and third with UIP alone. HRCT features of AEF and honeycombing were compared. Results: There were 11 patients (10 male; mean age 69) with AEF alone, 24 patients (22 male; mean age 69) with AEF and UIP, and 15 patients (15 male; mean age 68) with UIP alone. The HRCT on the AEF alone showed subpleural (but not abutting the pleura) multiple thin-walled cysts (MTWCs) in 7 and reticular opacities in 3. The HRCT in AEF and UIP showed MTWCs in 10, reticular opacities in 17; and honeycombing in 5. Among these 35 patients with the pathological finding of AEF (with or without UIP), 17 showed MTWCs. The maximum cyst wall thickness of MTWCs (mean 0.81 mm) was significantly thinner than that of honeycombing (mean 1.56 mm). MTWCs did not locate in lung base and was distant from the pleura. HRCT findings correlated with gross findings on both cysts and honeycombing. No MTWCs were seen in the 15 patients with UIP, 8 of 15 had

  12. Fidelity analysis of mechanically aided copying/enlarging of Jan van Eyck's Portrait of Niccolo Albergati

    Stork, David G.; Duarte, Marco

    2007-01-01

    The contemporary artist David Hockney has hypothesized that some early Renaissance painters secretly projected optical images onto their supports (canvas, paper, oak panel, ...), directly traced these projections, and then filled in the tracings with paint[1]. Hockney has presented somewhat impressionistic image evidence for this claim, but he and thin-film physicist Charles Falco also point to perspective anomalies, to the fidelity of passages in certain paintings, and to historical documents in search of support for this direct tracing claim[2]. Key visual evidence adduced in support of this tracing claim is a pair of portraits by Jan van Eyck of Cardinal Niccolo Albergati - a small informal silverpoint study of 1431 and a slightly larger formal work in oil on panel of 1432. The contours in these two works bear striking resemblance in shape (after being appropriately scaled) and there are at least two "relative shifts" - passages that co-align well after a spatial shift of one of the images [2]. This evidence has led the theory's proponents to claim that van Eyck copied the silverpoint by means of an optical projector, or epidiascope, the relative shifts due to him accidentally bumping the setup during the copying. Previous tests of the tracing theory for these works considered four candidate methods van Eyck might have used to copied and enlarged the image in the silverpoint study: unaided ("by eye"), mechanical, grid, and the optical projection method itself [3]. Based on the full evidence, including the recent discovery of tiny pinprick holes in the silverpoint, reenactments, material culture and optical knowledge in the early 15th century, the mechanical method was judged most plausible and optical method the least plausible[3]. However, this earlier work did not adequately test whether a trained artist could "re-enact" the copying by mechanical methods: "Although we have not explicitly verified that high fidelities can be achieved through the use of a

    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.)

  15. Severe Gingival Enlargement with Coexisting Erosive Lichen Planus in Severe Chronic Periodontitis Patient

    Ambika Sharma

    2015-01-01

    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.

  17. On buoyancy-driven natural ventilation of a room with a heated floor

    Gladstone, Charlotte; Woods, Andrew W.

    2001-08-01

    The natural ventilation of a room, both with a heated floor and connected to a cold exterior through two openings, is investigated by combining quantitative models with analogue laboratory experiments. The heated floor generates an areal source of buoyancy while the openings allow displacement ventilation to operate. When combined, these produce a steady state in which the air in the room is well-mixed, and the heat provided by the floor equals the heat lost by displacement. We develop a quantitative model describing this process, in which the advective heat transfer through the openings is balanced with the heat flux supplied at the floor. This model is successfully tested with observations from small-scale analogue laboratory experiments. We compare our results with the steady-state flow associated with a point source of buoyancy: for a given applied heat flux, an areal source produces heated air of lower temperature but a greater volume flux of air circulates through the room. We generalize the model to account for the effects of (i) a cooled roof as well as a heated floor, and (ii) an external wind or temperature gradient. In the former case, the direction of the flow through the openings depends on the temperature of the exterior air relative to an averaged roof and floor temperature. In the latter case, the flow is either buoyancy dominated or wind dominated depending on the strength of the pressure associated with the wind. Furthermore, there is an intermediate multiple-solution regime in which either flow regime may develop.

  18. Diagnosis of blow-out fracture of the orbital floor using a computed tomography

    Ishikawa, Yoshimi; Aoki, Shinjiroh; Ono, Shigeru; Fujita, Kiyohide

    1986-01-01

    Diagnosis of a blow-out fracture of the orbital floor is relatively easy from clinical and roentogen findings but information from these findings are not adequate for the decision for surgical indication. Until recently, computed tomography for the orbital region was generally performed only in axial plane. But the axial plane is parallel to the orbital structure, therefore it is difficult to visualize the orbital floor and inferior rectus muscle. On the other hand, coronal plane is cross-section to the orbital structure, and we can visualize the all orbital soft tissues including extraocular muscles. We examined 3 cases diagnosed as a blow-out fracture of the orbital floor by conventional roentogen films and clinical findings. After axial CT was performed firstly, the coronal CT was scanned with 60 degrees to 70 degrees from OM line, setting the patient in the hanging head position. Case 1 used coronal reformation of the axial CT data. Case 2 and case 3 used direct coronal scanning. By bi-plane CT we could diagnose whether inferior rectus muscle was entrapped or not, and confirm surgical indication. Using of a cadaver, we studied the mechanism for limitation of eye movement. These studies revealed that it is rare that the inferior rectus muscle is entrapped directly by fractured segments at the orbital anterior floor. Because there is a lot of orbital fat-pad between the inferior rectus muscle and the orbital floor, and it may play an important role. The limited mobility of the inferior rectus muscle may occur as a result of increased tension of the fibrous bands that attach to the muscle sheath from the prolapsed fat-pad, and contructure by scar formed secondarily. Diagnosis of the location of a fracture in the orbital floor and cause of the limitation of eye movement must be done as early as possible and from this information we can confirm surgical indication.

  19. Remote Sensing of shallow sea floor for digital earth environment

    Yahya, N N; Hashim, M; Ahmad, S

    2014-01-01

    Understanding the sea floor biodiversity requires spatial information that can be acquired from remote sensing satellite data. Species volume, spatial patterns and species coverage are some of the information that can be derived. Current approaches for mapping sea bottom type have evolved from field observation, visual interpretation from aerial photography, mapping from remote sensing satellite data along with field survey and hydrograhic chart. Remote sensing offers most versatile technique to map sea bottom type up to a certain scale. This paper reviews the technical characteristics of signal and light interference within marine features, space and remote sensing satellite. In addition, related image processing techniques that are applicable to remote sensing satellite data for sea bottom type digital mapping is also presented. The sea bottom type can be differentiated by classification method using appropriate spectral bands of satellite data. In order to verify the existence of particular sea bottom type, field observations need to be carried out with proper technique and equipment

  20. The effect of sub-floor heating on house-dust-mite populations on floors and in furniture.

    de Boer, Rob

    2003-01-01

    It is well known that dehydrating conditions for house dust mites can be created by simply raising the temperature, causing loss of body water and eventually death. Thus, it can be expected that conditions for dust mites are less favourable on floors supplied with sub-floor heating. This was examined in a study of 16 houses with sub-floor heating and 21 without. The pattern of changes in air humidity and temperature on the floors was investigated and compared to known data of the tolerance of dust mites. Also the resident mite populations were compared. Floors with sub-floor heating had, on average, fewer mites, but the difference with unheated floors was small. It was remarkable that mite numbers were also lower in upholstered furniture. Another important observation was that some houses with sub-floor heating had high mite numbers, indicating that this type of heating is compatible with a thriving mite population. Temperature and humidity conditions of heated floors may allow mites not only to survive, but also to remain active in winter. A moderate increase in temperature, a moderate decrease in (absolute) air humidity, or a combination of both, will suffice to keep the humidity all winter below the Critical Equilibrium Humidity, the level of air humidity that is critical for mite growth and reproduction, hence for allergen production. However, it is argued that measures to suppress allergen production by house dust mites are likely to be far more effective if taken in summer rather than in winter.

  1. Toxic and fire hazard of flooring

    Full Text Available polymer materials have become widespread in the modern construction industry due to their cheapness and variety. With regard to their popularity at the present time there can appear the issues of their toxic and fire danger. The work has studied the samples of two floor synthetic building materials. The results of the determination of the fire hazard indicators of materials (combustibility, flammability, smoke ratio showed their compliance with the current certificates. The authors have studied the properties of gaseous combustion products of samples by the method of thermal analysis and FTIR analysis. The results of chloride ions analysis according the formula of Maxwell-Mohr in thermolysis products indicate the toxicity of the materials studied.

  2. Improving the cleaning procedure to make kitchen floors less slippery.

    Quirion, F; Poirier, P; Lehane, P

    2008-12-01

    This investigation shows that, in most cases, the floor cleaning procedure of typical restaurants could be improved, resulting in a better cleaning efficiency and a better floor friction. This simple approach could help reduce slips and falls in the workplace. Food safety officers visited ten European style restaurants in the London Borough of Bromley (UK) to identify their floor cleaning procedure in terms of the cleaning method, the concentration and type of floor cleaner and the temperature of the wash water. For all 10 restaurants visited, the cleaning method was damp mopping. Degreasers were used in three sites while neutral floor cleaners were used in seven sites. Typically, the degreasers were over diluted and the neutrals were overdosed. The wash water temperature ranged from 10 to 72 degrees C. The on-site cleaning procedures were repeated in the laboratory for the removal of olive oil from new and sealed quarry tiles, fouled and worn quarry tiles and new porcelain tiles. It is found that in 24 out of 30 cases, cleaning efficiency can be improved by simple changes in the floor cleaning procedure and that these changes result in a significant improvement of the floor friction. The nature of the improved floor cleaning procedure depends on the flooring type. New and properly sealed flooring tiles can be cleaned using damp mopping with a degreaser diluted as recommended by the manufacturer in warm or hot water (24 to 50 degrees C). But as the tiles become worn and fouled, a more aggressive floor cleaning is required such as two-step mopping with a degreaser diluted as recommended by the manufacturer in warm water (24 degrees C).

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

    Persson, Johan

    2000-02-01

    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.

  4. Divergent axial morphogenesis and early shh expression in vertebrate prospective floor plate

    Stanislav Kremnyov

    2018-01-01

    Full Text Available Abstract Background The notochord has organizer properties and is required for floor plate induction and dorsoventral patterning of the neural tube. This activity has been attributed to sonic hedgehog (shh signaling, which originates in the notochord, forms a gradient, and autoinduces shh expression in the floor plate. However, reported data are inconsistent and the spatiotemporal development of the relevant shh expression domains has not been studied in detail. We therefore studied the expression dynamics of shh in rabbit, chicken and Xenopus laevis embryos (as well as indian hedgehog and desert hedgehog as possible alternative functional candidates in the chicken. Results Our analysis reveals a markedly divergent pattern within these vertebrates: whereas in the rabbit shh is first expressed in the notochord and its floor plate domain is then induced during subsequent somitogenesis stages, in the chick embryo shh is expressed in the prospective neuroectoderm prior to the notochord formation and, interestingly, prior to mesoderm immigration. Neither indian hedgehog nor desert hedgehog are expressed in these midline structures although mRNA of both genes was detected in other structures of the early chick embryo. In X. laevis, shh is expressed at the beginning of gastrulation in a distinct area dorsal to the dorsal blastopore lip and adjacent to the prospective neuroectoderm, whereas the floor plate expresses shh at the end of gastrulation. Conclusions While shh expression patterns in rabbit and X. laevis embryos are roughly compatible with the classical view of “ventral to dorsal induction” of the floor plate, the early shh expression in the chick floor plate challenges this model. Intriguingly, this alternative sequence of domain induction is related to the asymmetrical morphogenesis of the primitive node and other axial organs in the chick. Our results indicate that the floor plate in X. laevis and chick embryos may be initially

  5. Pelvic floor dysfunction, and effects of pregnancy and mode of delivery on pelvic floor

    Murat Bozkurt

    2014-12-01

    Full Text Available Pelvic floor dysfunction (PFD, although seems to be simple, is a complex process that develops secondary to multifactorial factors. The incidence of PFD is increasing with increasing life expectancy. PFD is a term that refers to a broad range of clinical scenarios, including lower urinary tract excretory and defecation disorders, such as urinary and anal incontinence, overactive bladder, and pelvic organ prolapse, as well as sexual disorders. It is a financial burden on the health care system and disrupts women's quality of life. Strategies applied to decrease PFD are focused on the course of pregnancy, mode and management of delivery, and pelvic exercise methods. Many studies in the literature define traumatic birth, usage of forceps, length of the second stage of delivery, and sphincter damage as modifiable risk factors for PFD. Maternal age, fetal position, and fetal head circumference are nonmodifiable risk factors. Although numerous studies show that vaginal delivery affects pelvic floor structures and their functions in a negative way, there is not enough scientific evidence to recommend elective cesarean delivery in order to prevent development of PFD. PFD is a heterogeneous pathological condition, and the effects of pregnancy, vaginal delivery, cesarean delivery, and possible risk factors of PFD may be different from each other. Observational studies have identified certain obstetrical exposures as risk factors for pelvic floor disorders. These factors often coexist; therefore, the isolated effects of these variables on the pelvic floor are difficult to study. The routine use of episiotomy for many years in order to prevent PFD is not recommended anymore; episiotomy should be used in selected cases, and the mediolateral procedures should be used if needed.

  6. Pure myopathy with enlarged mitochondria associated to a new mutation in MTND2 gene

    Alice Zanolini

    2017-03-01

    Full Text Available To date, only few mutations in the mitochondrial DNA (mtDNA-encoded ND2 subunit of Complex I have been reported, usually presenting a severe phenotype characterized by early onset encephalomyopathy and early death. In this report, we describe a new mutation in the MTND2 gene in a 21-year-old man with a mild myopathic phenotype characterized by exercise intolerance and increased plasma lactate at rest. Electromyography and brain NMR were normal, and no cardiac involvement was present. Muscle biopsy showed a massive presence of ragged red – COX-positive fibres, with enlarged mitochondria containing osmiophilic inclusions. Biochemical assays revealed a severe isolated complex I deficiency. We identified a novel, heteroplasmic mutation m.4831G>A in the MTND2 gene, causing the p.Gly121Asp substitution in the ND2 protein. The mutation was present in the 95% of mitochondrial genomes from patient's muscle tissue, at a lower level in cells from the urinary tract and at a lowest level in lymphocytes from patient's blood; the base substitution was absent in fibroblasts and in the tissues from proband's healthy mother and brother. The specific skeletal muscle tissue involvement can explain the childhood-onset and the relatively benign, exclusively myopathic course of the disease.

  7. CREB Regulates Experience-Dependent Spine Formation and Enlargement in Mouse Barrel Cortex

    Annabella Pignataro

    2015-01-01

    Full Text Available Experience modifies synaptic connectivity through processes that involve dendritic spine rearrangements in neuronal circuits. Although cAMP response element binding protein (CREB has a key function in spines changes, its role in activity-dependent rearrangements in brain regions of rodents interacting with the surrounding environment has received little attention so far. Here we studied the effects of vibrissae trimming, a widely used model of sensory deprivation-induced cortical plasticity, on processes associated with dendritic spine rearrangements in the barrel cortex of a transgenic mouse model of CREB downregulation (mCREB mice. We found that sensory deprivation through prolonged whisker trimming leads to an increased number of thin spines in the layer V of related barrel cortex (Contra in wild type but not mCREB mice. In the barrel field controlling spared whiskers (Ipsi, the same trimming protocol results in a CREB-dependent enlargement of dendritic spines. Last, we demonstrated that CREB regulates structural rearrangements of synapses that associate with dynamic changes of dendritic spines. Our findings suggest that CREB plays a key role in dendritic spine dynamics and synaptic circuits rearrangements that account for new brain connectivity in response to changes in the environment.

  8. Ventricular enlargement in multiple sclerosis: a comparison of three-dimensional and linear MRI estimates

    Turner, B.; Blumhardt, L.D.; Ramli, N.; Jaspan, T.

    2001-01-01

    Atrophy of central white matter is related to irreversible clinical disability in multiple sclerosis (MS) and ventricular enlargement may be a sensitive marker of this tissue loss. Therapeutic trials in MS have provided MRI data for investigation of cerebral atrophy in MS. These studies use almost exclusively two-dimensional (2-D) images, which may be limited in the assessment of three-dimensional (3-D) structures. We used 3-D MRI data to estimate ventricular volumes in 40 patients with MS and 10 healthy controls, to look at associations with clinical disability and the stage of the disease. We then compared simple linear measures of ventricular size from conventional 2-D images, with 3-D volume estimates to establish the best available linear indices of ventricular volume. Mean ventricular volumes were increased in the patients and significantly larger in the more disabled patients. The estimated volume of the third ventricle obtained from 3-D MRI showed the strongest association with the clinical stage of the disease, duration of symptoms and levels of disability. Finally, we confirmed that in patients with MS accurate data on ventricular size can be obtained from 2-D images by two simple and convenient linear measures, the width of the third ventricle and of the anterior horn of the lateral ventricle.

  9. Generation of floor response spectra for mixed-oxide fuel fabrication plants

    Arthur, D.F.; Murray, R.C.; Tokarz, F.J.

    1975-01-01

    Floor or amplified response spectra are generally used as input motion for seismic analysis of critical equipment and piping in nuclear power plants and related facilities. The floor spectra are normally the result of a time-history calculation of building response to ground shaking. However, alternate approximate methods have been suggested by both Kapur and Biggs. As part of a study for the Nuclear Regulatory Commission horizontal floor response spectra were generated and compared by all three methods. The dynamic analyses were performed on a model of the Westinghouse Recycle Fuels Plant Manufacturing Building (MOFFP). Input to the time-history calculations was a synthesized accelerogram whose response spectrum is similar to that in Regulatory Guide 1.60. The response spectrum of the synthetic ground motion was used as input to the Kapur and Biggs methods. Calculations were performed for both hard (3500 fps) and soft (1500 fps) foundation soils. Results of comparison of the three methods indicate that although the approximate methods could easily be made acceptable from a safety standpoint, they would be overly conservative. The time-history method will yield floor spectra which are less uncertain and less conservative for a relatively modest additional effort. (auth)

  12. Short communication: Flooring preferences of dairy cows at calving.

    Campler, M; Munksgaard, L; Jensen, M B; Weary, D M; von Keyserlingk, M A G

    2014-02-01

    The present study investigated the flooring preference during the 30 h before parturition in Holstein dairy cows housed individually in a maternity pen. Seventeen multiparous cows were moved, on average, 2 d before expected calving date into an individual maternity pen with 3 different flooring surfaces: 10 cm of sand, pebble-top rubber mats, or concrete flooring, each covered with 15 cm of straw. Calving location, lying time, and total time and number of lying bouts on each of the floor types were recorded during 2 periods: precalving (24 to 29 h before calving) and at calving (0 to 5h before calving). Ten cows calved on sand, 6 on concrete, and 1 on the rubber mat. Lying bouts increased during the hours closest to calving, regardless of flooring. The number of lying bouts did not differ between flooring types precalving but cows had more lying bouts on sand and concrete compared with rubber at calving. Cows spent more time lying down on sand and concrete compared with rubber precalving, but lying times did not differ between treatments at calving. Cows that calved on sand spent more time lying on sand at calving compared with the other 2 flooring types. Cows that calved on concrete did not show a flooring preference at calving. These results indicate that rubber mats are the least preferred by dairy cows in the maternity pens, even when covered with a deep layer of straw. Copyright © 2014 American Dairy Science Association.

  15. Experimental Verification of an Instrument to Test Flooring Materials

    Philip, Rony; Löfgren, Hans, Dr

    2018-02-01

    The focus of this work is to validate the fluid model with different flooring materials and the measurements of an instrument to test flooring materials and its force attenuating capabilities using mathematical models to describe the signature and coefficients of the floor. The main contribution of the present work focus on the development of a mathematical fluid model for floors. The aim of the thesis was to analyze, compare different floor materials and to study the linear dynamics of falling impacts on floors. The impact of the hammer during a fall is captured by an accelerometer and response is collected using a picoscope. The collected data was analyzed using matlab least square method which is coded as per the fluid model. The finding from this thesis showed that the fluid model works with more elastic model but it doesn’t work for rigid materials like wood. The importance of parameters like velocity, mass, energy loss and other coefficients of floor which influences the model during the impact of falling on floors were identified and a standardized testing method was set.

  19. Motor cortical representation of the pelvic floor muscles.

    Schrum, A; Wolff, S; van der Horst, C; Kuhtz-Buschbeck, J P

    2011-07-01

    Pelvic floor muscle training involves rhythmical voluntary contractions of the external urethral sphincter and ancillary pelvic floor muscles. The representation of these muscles in the motor cortex has not been located precisely and unambiguously. We used functional magnetic resonance imaging to determine brain activity during slow and fast pelvic floor contractions. Cerebral responses were recorded in 17 healthy male volunteers, 21 to 47 years old, with normal bladder control. Functional magnetic resonance imaging was performed during metronome paced slow (0.25 Hertz) and fast (0.7 Hertz) contractions of the pelvic floor that mimicked the interruption of voiding. To study the somatotopy of the cortical representations, flexion-extension movements of the right toes were performed as a control task. Functional magnetic resonance imaging during pelvic floor contractions detected activity of the supplementary motor area in the medial wall and of the midcingulate cortex, insula, posterior parietal cortex, putamen, thalamus, cerebellar vermis and upper ventral pons. There were no significant differences in activation between slow and fast contractions. Toe movements involved significantly stronger activity of the paracentral lobule (ie the medial primary motor cortex) than did the pelvic floor contractions. Otherwise the areas active during pelvic floor and leg muscle contractions overlapped considerably. The motor cortical representation of pelvic floor muscles is located mostly in the supplementary motor area. It extends further ventrally and anteriorly than the representation of distal leg muscles.

  1. Recognition and Management of Nonrelaxing Pelvic Floor Dysfunction

    Faubion, Stephanie S.; Shuster, Lynne T.; Bharucha, Adil E.

    2012-01-01

    Nonrelaxing pelvic floor dysfunction is not widely recognized. Unlike in pelvic floor disorders caused by relaxed muscles (eg, pelvic organ prolapse or urinary incontinence, both of which often are identified readily), women affected by nonrelaxing pelvic floor dysfunction may present with a broad range of nonspecific symptoms. These may include pain and problems with defecation, urination, and sexual function, which require relaxation and coordination of pelvic floor muscles and urinary and anal sphincters. These symptoms may adversely affect quality of life. Focus on the global symptom complex, rather than the individual symptoms, may help the clinician identify the condition. The primary care provider is in a position to intervene early, efficiently, and effectively by (1) recognizing the range of symptoms that might suggest nonrelaxing pelvic floor dysfunction, (2) educating patients, (3) performing selective tests when needed to confirm the diagnosis, and (4) providing early referral for physical therapy.

  2. Historical Cavern Floor Rise for All SPR Sites

    Moriarty, Dylan Michael [Sandia National Lab. (SNL-NM), Albuquerque, NM (United States)

    2016-09-01

    The Strategic Petroleum Reserve (SPR) contains the largest supply is the largest stockpile of government-owned emergency crude oil in the world. The oil is stored in multiple salt caverns spread over four sites in Louisiana and Texas. Cavern infrastructure near the bottom of the cavern can be damaged from vertical floor movement. This report presents a comprehensive history of floor movements in each cavern. Most of the cavern floor rise rates ranged from 0.5-3.5 ft/yr, however, there were several caverns with much higher rise rates. BH103, BM106, and BH105 had the three highest rise rates. Information from this report will be used to better predict future vertical floor movements and optimally place cavern infrastructure. The reasons for floor rise are not entirely understood and should be investigated.

    Malignant osseous and soft-tissue tumors of the foot are rare. We report a case of osteosarcoma in the proximal phalanx of the hallux in a 45-year-old man. In patients with foot-related symptoms, a high index of suspicion for pedal osteosarcoma is required. Delayed or inappropriate diagnosis may compromise limb-sparing surgery and survivorship.

  4. Evaluation of Floor Response Spectrum considering Ductility of Structure

    Park, Junhee; Choi, In-Kil

    2014-01-01

    The FRS (floor response spectrum) is directly influenced by the behavior of structure under the seismic load. If the structure is nonlinear range, the energy dissipation will be occurred by the damage of structure and the maximum force will be reduced. In Zion method, the inelastic energy abortion factor has been used to consider the nonlinearity of structure. This factor was used for the seismic fragility of structure. For the seismic fragility of equipment, the uncertainty of this factor was used differently according to the story level. But this method is not warranted under the strong earthquake leads to the structural damage. Therefore it is needed to evaluate the FRS considering the nonlinear behavior of structure and to assessment the conservatism related to nonlinear behavior of structure in FRS. In this study, the nonlinear analysis was performed for the conservatism of FRS under the damage of structure. The conservatism of FRS by the nonlinear analysis was compared by that proposed by the Zion method. The conservatism of floor acceleration response for the equipment was evaluated by performing the nonlinear analysis. From the nonlinear analysis results, it was showed that the median and β c of FRSR was increased with the ductility of structure and the response of equipment had the resonance effect between the frequency of equipment and structure. The seismic capacity of equipment by the Zion method can be different from the real seismic capacity of equipment because the inelastic structure response factor has nothing to do with the ductility of structure. Therefore the median and COV for FRSR should be defined considering the ductility of structure and the frequency of equipment for more exactly evaluating the seismic capacity of equipment

    1987-01-01

    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)

  8. Tumescent power liposuction in the treatment of the enlarged male breast.

    Boni, Roland

    2006-01-01

    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.

  9. Enlargement of lumbar spinal canal in lumbar degenerative spondylolisthesis. Evaluation with three-dimensional computed tomography

    Kunishi, Yoshihiko

    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)

  10. Pain following foraminal enlargement in mandibular molars with necrosis and apical periodontitis: A randomized controlled trial.

    Saini, H R; Sangwan, P; Sangwan, A

    2016-12-01

    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.

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

    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.

  14. Factors influencing long-term adherence to pelvic floor exercises in women with urinary incontinence.

    Venegas, Mónica; Carrasco, Bernardita; Casas-Cordero, Romina

    2018-03-01

    To ensure the effectiveness of Physical Therapy for urinary incontinence (UI), it is crucial that patients adhere to treatment in both the long and the short term. Treatment adherence may prevent symptom progression and the need for surgery, which is associated with higher costs and potential complications. Adherence is defined as carrying out a recommended behavioral modification or change. The World Health Organization (WHO) has established that adherence is a multifactorial phenomenon determined by the interaction of five dimensions, which include diverse factors that affect long-term adherence on many levels. To identify the factors that influence long-term adherence to pelvic floor exercises in women with UI. Observational, descriptive, cross-sectional study. The sample was recruited from the "Centro Integral de Reeducación de Piso Pélvico" (CIREP), and included 61 women treated for UI at the center in 2014 and 2015. Participants completed a self-administered, 28-item questionnaire developed for this study based on the WHO five dimensions. Data analysis was performed using STATA 13.0 software. Having performed pelvic floor home exercises after discharge from Physical Therapy was significantly associated with self-rated treatment adherence (P pelvic floor exercise program (P pelvic floor exercises in women with UI; forgetting to do the exercises and boredom with the exercises were the factors most strongly related to low treatment adherence, while motivation and commitment were associated with high adherence in this population. © 2017 Wiley Periodicals, Inc.

  15. Mechanical model of water inrush from coal seam floor based on triaxial seepage experiments

    Yihui Pang; Guofa Wang; Ziwei Ding

    2014-01-01

    In order to study the mechanism of confined water inrush from coal seam floor, the main influences on permeability in the process of triaxial seepage experiments were analyzed with methods such as laboratory experiments, theoretical analysis and mechanical model calculation. The crack extension rule and the ultimate destruction form of the rock specimens were obtained. The mechanism of water inrush was explained reasonably from mechanical point of view. The practical criterion of water inrush was put forward. The results show that the rock permeability ‘‘mutation’’ phe-nomenon reflects the differences of stress state and cracks extension rate when the rock internal crack begins to extend in large-scale. The rock ultimate destruction form is related to the rock lithology and the angle between crack and principal stress. The necessary condition of floor water inrush is that the mining pressure leads to the extension and transfixion of the crack. The sufficient condition of floor water inrush is that the confined water’s expansionary stress in normal direction and shear stress in tangential direction must be larger than the internal stress in the crack. With the two conditions satisfied at the same time, the floor water inrush accident will occur.

    Knowledge of risk factors is particularly useful to prevent or manage pelvic floor dysfunction but although a number of such factors have been proposed, results remain inconsistent. The purpose of this study was to evaluate the impact of aging on the incidence of posterior pelvic floor disorders in women with obstructed defecation syndrome evaluated using echodefecography. A total of 334 patients with obstructed defecation were evaluated using echodefecography in order to quantify posterior pelvic floor dysfunction (rectocele, intussusception, mucosal prolapse, paradoxical contraction or non-relaxation of the puborectalis muscle, and grade III enterocele/sigmoidocele). Patients were grouped according to the age (Group I = patients up to 50 years of age; Group II = patients over 50 years of age) to evaluate the isolated and associated incidence of dysfunctions. To evaluate the relationship between dysfunction and age-related changes, patients were also stratified into decades. Group I included 196 patients and Group II included 138. The incidence of significant rectocele, intussusception, rectocele associated with intussusception, rectocele associated with mucosal prolapse and 3 associated disorders was higher in Group II, whereas anismus was more prevalent in Group I. The incidence of significant rectocele, intussusception, mucosal prolapse and grade III enterocele/sigmoidocele was found to increase with age. Conversely, anismus decreased with age. Aging was shown to influence the incidence of posterior pelvic floor disorders (rectocele, intussusception, mucosa prolapse and enterocele/sigmoidocele), but not the incidence of anismus, in women with obstructed defecation syndrome.

  17. Dose-Effect Relationships for Individual Pelvic Floor Muscles and Anorectal Complaints After Prostate Radiotherapy

    2012-01-01

    Purpose: To delineate the individual pelvic floor muscles considered to be involved in anorectal toxicity and to investigate dose-effect relationships for fecal incontinence-related complaints after prostate radiotherapy (RT). Methods and Materials: In 48 patients treated for localized prostate cancer, the internal anal sphincter (IAS) muscle, the external anal sphincter (EAS) muscle, the puborectalis muscle (PRM), and the levator ani muscles (LAM) in addition to the anal wall (Awall) and rectal wall (Rwall) were retrospectively delineated on planning computed tomography scans. Dose parameters were obtained and compared between patients with and without fecal urgency, incontinence, and frequency. Dose-effect curves were constructed. Finally, the effect of an endorectal balloon, which was applied in 28 patients, was investigated. Results: The total volume of the pelvic floor muscles together was about three times that of the Awall. The PRM was exposed to the highest RT dose, whereas the EAS received the lowest dose. Several anal and rectal dose parameters, as well as doses to all separate pelvic floor muscles, were associated with urgency, while incontinence was associated mainly with doses to the EAS and PRM. Based on the dose-effect curves, the following constraints regarding mean doses could be deduced to reduce the risk of urgency: ≤30 Gy to the IAS; ≤10 Gy to the EAS; ≤50 Gy to the PRM; and ≤40 Gy to the LAM. No dose-effect relationships for frequency were observed. Patients treated with an endorectal balloon reported significantly less urgency and incontinence, while their treatment plans showed significantly lower doses to the Awall, Rwall, and all pelvic floor muscles. Conclusions: Incontinence-related complaints show specific dose-effect relationships to individual pelvic floor muscles. Dose constraints for each muscle can be identified for RT planning. When only the Awall is delineated, substantial components of the continence apparatus are

  20. Analysis of reforming process of large distorted ring in final enlarging forging

    Miyazawa, Takeshi; Murai, Etsuo

    2002-01-01

    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)

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.

    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.

    Lukierski, J.; Stichel, P. C.; Zakrzewski, W. J.

    2008-05-01

    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.

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

    Sanjeev Joshi

    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.

  5. Etiologic significance of enlargement of the left atrial appendage in adults

    Green, C.E.; Kelley, M.J.; Higgins, C.B.

    1982-01-01

    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 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.

  8. Radon reduction using sub floor fans

    Harley, N.H.; Chittaporn, P.

    1996-01-01

    The basement and second floor 222 Rn concentrations in an energy efficient home were measured hourly for 6 y using continuous monitors of our design. The home had a subslab pipe network installed during construction, and for the past 2 y a 150 cfm fan was operative venting air via ductwork inside the chimney exiting on the roof. During this measurement interval, experiments were conducted with the fan in 3 modes: (1) with the subslab fan off, (2) in the conventional direction auctioning air from beneath the slab to outside, and (3) reversed, blowing outdoor air into the network under the slab. We have a large data base to show that the indoor 222 R n concentration varies inversely with the indoor/outdoor temperature difference. In order to compare the 3 fan modes directly, we selected 50 to 90 d periods when the outdoor temperature was essentially the same. For the 3 modes, the fan off, blowing upward, and blowing downward, the basement concentration averaged 80, 38, and 34 Bq m -3 , respectively. Radon peaks or surges occur over a period of about 1 d during falling barometric pressure. With the fan blowing downward, these 222 Rn peaks tend to be smaller but only marginally so. We conclude that in this home the reduction in 222 Rn with the fan and subslab pipe network operating was essentially the same regardless of the direction of flow from the fan

  9. Nuclear wastes beneath the deep sea floor

    Bishop, W.P.; Hollister, C.D.

    1974-01-01

    Projections of energy demands for the year 2000 show that nuclear power will likely be one of our energy sources. But the benefits of nuclear power must be balanced against the drawbacks of its by-product: high-level wastes. While it may become possible to completely destroy or eliminate these wastes, it is at least equally possible that we may have to dispose of them on earth in such a way as to assure their isolation from man for periods of the order of a million years. Undersea regions in the middle of tectonic plates and in the approximate center of major current gyres offer some conceptual promise for waste disposal because of their geologic stability and comparatively low organic productivity. The advantages of this concept and the types of detailed information needed for its accurate assessment are discussed. The technical feasibility of permanent disposal beneath the deep sea floor cannot be accurately assessed with present knowledge, and there is a need for a thorough study of the types and rates of processes that affect this part of the earth's surface. Basic oceanographic research aimed at understanding these processes is yielding answers that apply to this societal need. (U.S.)

  10. Floor-Fractured Craters through Machine Learning Methods

    Thorey, C.

    2015-12-01

    Floor-fractured craters are impact craters that have undergone post impact deformations. They are characterized by shallow floors with a plate-like or convex appearance, wide floor moats, and radial, concentric, and polygonal floor-fractures. While the origin of these deformations has long been debated, it is now generally accepted that they are the result of the emplacement of shallow magmatic intrusions below their floor. These craters thus constitute an efficient tool to probe the importance of intrusive magmatism from the lunar surface. The most recent catalog of lunar-floor fractured craters references about 200 of them, mainly located around the lunar maria Herein, we will discuss the possibility of using machine learning algorithms to try to detect new floor-fractured craters on the Moon among the 60000 craters referenced in the most recent catalogs. In particular, we will use the gravity field provided by the Gravity Recovery and Interior Laboratory (GRAIL) mission, and the topographic dataset obtained from the Lunar Orbiter Laser Altimeter (LOLA) instrument to design a set of representative features for each crater. We will then discuss the possibility to design a binary supervised classifier, based on these features, to discriminate between the presence or absence of crater-centered intrusion below a specific crater. First predictions from different classifier in terms of their accuracy and uncertainty will be presented.

    Segedi, Ljiljana Mladenović; Ilić, Katarina Parezanović; Curcić, Aleksandar; Visnjevac, Nemanja

    2011-11-01

    Pelvic floor dysfunction is a frequent problem affecting more than 50% of women in peri- and postmenopause. Considering that ageing and menopause befall in the significant factors causing this issue, as well as the expected longevity of women in the world and in our country, pelvic floor dysfunction prevelence is foreseen to be even higher. The aim of the study was to evaluate impact of the symptoms of pelvic dysfunction on quality of life and examine body image satisfaction in adult women with pelvic organ prolapse presenting to tertiary care clinic for surgical treatment. This prospective case-control study included 50 patients who presented to tertiary care gynecology clinic for surgical treatment and 50 controls with normal pelvic floor support and without urinary incontinence who presented tertiary care gynecology clinic for other reasons. Both, patients and controls, completed two quastionnaires recommended for the evaluation of symptoms (Pelvic floor distress inventory - short forms) and quality of life impact (Pelvic floor impact questionnaire - short form) of pelvic organ prolapse, and Body Image Scale. The patients scored significantly worse on the prolapse, urinary, colorectal scales and overall score of Pelvic floor distress inventory--20 than controls subjects (134.91 vs 78.08; p self-conscious (78% vs 42%; p body. There was a positive correlation between decreased quality of life and body image in women with pelvic dysfunction. Women with pelvic floor dysfunction have decreased quality of life and body image.

  12. Industrial tests of rock consolidation for fighting floor swelling

    Pirskii, A A; Stovpnik, S N [KPI (USSR)

    1990-04-01

    Reports on investigations into the mechanism of floor swelling in main roadways and into rock mass stabilization by consolidating fluid injection combined with blasting. The principal cause of deterioration in the stability of workings is considered to be the state of stress in the rock mass, rock destruction in side walls where rock blocks are being pressed into the floor while the floor rock is squeezed out into the working space. A case study of fluid injection combined with blasting applied in several mines in the Donbass is presented where holes were drilled 1.5-3 m deep and explosive charges of 0.07-0.1 kg/hole and injection of hardening solutions (0.56-0.83 m{sup 3}/m of workings) were applied. As a result floor swelling rates were reduced by up to about 5 times (e.g. from 2.5 mm/d to 0.5 mm/d.). The period of maintenence free upkeep of workings was extended to 6-8 years. The economic effect in maintenance of 1 m of workings was 11.7 rubles for floor consolidation without sidewall bolting and 51.4 rubles for floor consolidation combined with sidewall bolting. Recommendations that concern the technology of floor consolidation by fluid injection and blasting are made. 4 refs.

    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.

    Enlarged perivascular spaces (EPVS) have been identified as a marker of cerebral small vessel diseases (CSVD). Ambulatory blood pressure (ABP) is the strongest predictor of hypertension-related brain damage. However, the relationship between ABP levels and EPVS is unclear. This study aimed to investigate the association between ABP levels and EPVS by 24-hour ambulatory blood pressure monitoring (ABPM). We prospectively recruited inpatients for physical examinations in our hospital from May 2013 to Jun 2016. 24-hour ABPM data and cranial magnetic resonance imaging information were collected. EPVS in basal ganglia (BG) and centrum semiovale (CSO) were identified and classified into three categories by the severity. White matter hyperintensities were scored by Fazekas scale. Spearman correlation analysis and multiple logistic regression analysis were used to determine the relationship between ABP levels and EPVS. A total of 573 subjects were enrolled in this study. 24-hour, day and night systolic blood pressure (SBP) levels were positively related to higher numbers of EPVS in BG (24-hour SBP: r = 0.23, p blood pressure (DBP) levels increased with an increasing degree of EPVS in CSO (p = 0.04 and 0.049, respectively). But the association disappeared after adjusting for confounders. Spearman correlation analysis indicated that ABP levels were not associated with higher numbers of EPVS in CSO (p > 0.05). DBP levels were not independently associated with the severity of EPVS in BG and CSO. Higher SBP levels were independently associated with EPVS in BG, but not in CSO, which supported EPVS in BG to be a marker of CSVD. Pathogenesis of EPVS in BG and CSO might be different.

  15. Development of Romanian Nuclear Power Program implications for future's EU enlargement

    Havris, A.

    2002-01-01

    Energy and transport are two areas for which relations with third countries are crucial. Transport is of course essential in order to ensure smooth movements of people and economic operators within the EU but also with the outside world. Its importance becomes even more apparent in a period characterised by globalization. If modes of transport are the arteries of our society, then energy is the blood. The Green Paper on the security of EU energy supply issued by the Commission shows that whereas the EU economy is energy-intensive, Community energy resources are limited. Consequently, the EU is dependent on external sources of energy, a situation which will not change with the forthcoming enlargement. Hence, most of the EU's external relations include an important chapter on energy. The instrument for applying Romania's pre-accession strategy is the National Programme for Accession (NPAR). I focused on the current situation, short and medium term priorities of the Nuclear Energy as part of the Energy Chapter of the NPAR. In spite of the Romanian Authorities' strong commitment for the completion of Unit2, obtaining the EURATOM loan, for which Societatea Nationala Nuclearelectrica S.A. applied to the European Commission in 1999, remained a critical component of the overall financing requirements of this project. The National Strategy for the Development of the Energy Sector on Medium Term 2001- 2004, as part of our national economic strategy, concludes that on a least-cost basis and considering programs for improving energy efficiency, it is necessary to have Cernavoda Unit 2 in operation by 2006. Finally, are presented the benefits for Romania, as a country involved in the process of European Integration, with a view to obtaining the EURATOM loan and finalizing Cernavoda NPP - Unit2.(author)

  16. Compositional Approach to Designing Fcc High-Entropy Alloys that Have an Enlarged Equiaxed Zone

    2018-01-01

    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.

    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.

    Jadhav, Tanya; Bhat, K Mahalinga; Bhat, G Subraya; Varghese, Jothi M

    2013-02-01

    Gingival enlargement, also synonymous with the terms gingival hyperplasia or hypertrophy, is defined as an abnormal overgrowth of gingival tissues. A case of a 19-year-old male presenting with maxillary and mandibular chronic inflammatory gingival enlargement associated with prolonged orthodontic therapy is reported here. Surgical therapy was carried out to provide a good aesthetic outcome. No recurrence was reported at the end of 1 year. The importance of patient motivation and compliance during and after therapy as a critical factor in the success of treatment has also been highlighted through this case report.

  19. Association between preterm labour and pelvic floor muscle function.

    Aran, Turhan; Pekgöz, Ipek; Bozkaya, Hasan; Osmanagaoglu, Mehmet A

    2018-03-23

    We hypothesised that the pressure on the cervix increases with advancing gestation and it may lead to a cervical shortening and cause preterm labour in women with weak pelvic floor muscles. The aim of this prospective study was to measure vaginal resting pressure and pelvic floor muscle strength in the first trimester of pregnancy and to investigate their effects on labour. A study was conducted on the pregnant women with a low risk for preterm birth. The pelvic floor muscle strength and vaginal resting pressure were assessed in 320 pregnant women at their first trimester with a vaginal pressure measurement device. Fifty-two pregnant women were hospitalised for tocolytic therapy because of spontaneous preterm labour. Thirty-two of them (10.2%) had a preterm delivery despite the tocolytic therapy. Both the vaginal resting pressure (p = .009, 95%CI: 0.8; 5.9) and the pelvic floor muscle strength (p = .01, 95%CI: 3.5; 13.1) were significantly lower in the women with a preterm labour. Impact statement What is already known on this subject? The pelvic floor muscles have an essential role in continence and provide support to the pelvic organs. They also have an impact on labour. The pelvic floor muscles should distend to allow the passage of the foetus during labour. The rotation and flexion of the foetal head is due to the pelvic floor resistance. The effect of a vaginal birth on the pelvic floor's function is readily understood. On the other hand, the effect of the pelvic floor muscle function on labour is still controversial. What do the results of this study add? This prospective study showed that there is a negative association between the pelvic floor muscle strength and preterm labour. This is the first clinical study indicating that weak pelvic floor muscles may cause a preterm labour. What are the implications of these findings for clinical practice and/or further research? Pelvic floor physical therapy may be an alternative preventive strategy to reduce

    2017-09-01

    Vulvar pain affects up to 20% of women at some point in their lives, and most women with vulvar pain have associated pelvic floor impairments. Pelvic floor dysfunction is associated with significant functional limitations in women by causing painful intercourse and urinary, bowel, and sexual dysfunction. A quick screening of the pelvic floor muscles can be performed in the gynecology office and should be used when patients report symptoms of pelvic pain. It is now known the vulvar pain syndromes are heterogeneous in origin; therefore, successful treatment plans are multimodal and include physical therapy. Copyright © 2017 Elsevier Inc.

    2003-10-01

    Several urogynecologic syndromes are associated with the clinical finding of a short, painful, tender and weak pelvic floor and a variety of connective tissue abnormalities. Techniques for rehabilitation include the avoidance of perpetuating factors, rehabilitation of extrapelvic musculoskeletal abnormalities, the use of manual techniques and needling to promote resolution of connective tissue problems, closure of any diastasis recti, and transvaginal/transrectal manual release of muscular trigger points and contractures. Therapy can be facilitated by pudendal or epidural nerve block. Patients contribute to their success through home maintenance programs.

    To evaluate continuous improvement of portable domestic pelvic floor neuromuscular electrical stimulation on the pelvic floor function of patients with stress urinary incontinence after short-term pelvic floor electrophysiological treatment in hospital. Totally 60 women with stress urinary incontinence were recruited for this randomized controlled trial. The control group including a total of 30 patients, only received 4 weeks pelvic floor electrophysiological treatment in the hospital. Family consolidation treatment group (experimental group) including 30 patients, after 4-week treatment in hospital, received 12-week of pelvic floor neuromuscular electrical stimulation using portable electrical stimulator at home under the guidance of doctors. In post-treatment 6 months and 9 months, 1-hour pad test was measured for urine leakage, pelvic floor electrical physiological parameters were assessed, and subjective improvement of symptoms of urinary incontinence were evaluated. All these data were analysed to compare the effect of the two groups. In 9 months after treatment, average change of urine leakage, the control group and experiment group were (75±24)% versus (99±3)%, the difference was statistically significant (Pcontinuous improvement of pelvic floor function.

  5. THE GENERATION OF BUILDING FLOOR PLANS USING PORTABLE AND UNMANNED AERIAL VEHICLE MAPPING SYSTEMS

    G. J. Tsai

    2016-06-01

    Full Text Available Indoor navigation or positioning systems have been widely developed for Location-Based Services (LBS applications and they come along with a keen demand of indoor floor plans for displaying results even improving the positioning performance. Generally, the floor plans produced by robot mapping focus on perceiving the environment to avoid obstacles and using the feature landmarks to update the robot position in the relative coordinate frame. These maps are not accurate enough to incorporate to the indoor positioning system. This study aims at developing Indoor Mobile Mapping System (Indoor MMS and concentrates on generating the highly accurate floor plans based on the robot mapping technique using the portable, robot and Unmanned Aerial Vehicles (UAV platform. The proposed portable mapping system prototype can be used in the chest package and the handheld approach. In order to evaluate and correct the generated floor plans from robot mapping techniques, this study builds the testing and calibration field using the outdoor control survey method implemented in the indoor environments. Based on control points and check points from control survey, this study presents the map rectification method that uses the affine transformation to solve the scale and deformation problems and also transfer the local coordinate system into world standard coordinate system. The preliminary results illustrate that the final version of the building floor plan reach 1 meter absolute positioning accuracy using the proposed mapping systems that combines with the novel map rectification approach proposed. These maps are well geo-referenced with world coordinate system thus it can be applied for future seamless navigation applications including indoor and outdoor scenarios.

  6. Regulatory Guide 1.122: Development of floor design response spectra for seismic design of floor-supported equipment or components

    Anon.

    1993-01-01

    ''Reactor Site Criteria,'' requires, in part, that safety-related structures, systems, and components remain functional in the event of a Safe Shutdown Earthquake (SSE). It specifies the use of a suitable dynamic analysis as one method of ensuring that the structures, systems, and components can withstand the seismic loads. Similarly, paragraph (a)(2) of Section VI of the same appendix requires, in part, that the structures, systems, and components necessary for continued operation without undue risk to the health and safety of the public remain functional in the event of an Operating Basis Earthquake (OBE). Again, the use of suitable dynamic analysis is specified as one method of ensuring that the structures, systems, and components can withstand the seismic loads. This guide describes methods acceptable to the NRC staff for developing two horizontal and one vertical floor design response spectra at various floors or other equipment-support locations of interest from the time-history motions resulting from the dynamic analysis of the supporting structure. These floor design response spectra are needed for the dynamic analysis of the systems or equipment supported at various locations of the supporting structure

    Modeling pedestrian movement is an interesting problem both in statistical physics and in computational physics. Update schemes of cellular automaton (CA) models for pedestrian dynamics govern the schedule of pedestrian movement. Usually, different update schemes make the models behave in different ways, which should be carefully recalibrated. Thus, in this paper, we investigated the influence of four different update schemes, namely parallel/synchronous scheme, random scheme, order-sequential scheme and shuffled scheme, on pedestrian dynamics. The multi-velocity floor field cellular automaton (FFCA) considering the changes of pedestrians' moving properties along walking paths and heterogeneity of pedestrians' walking abilities was used. As for parallel scheme only, the collisions detection and resolution should be considered, resulting in a great difference from any other update schemes. For pedestrian evacuation, the evacuation time is enlarged, and the difference in pedestrians' walking abilities is better reflected, under parallel scheme. In face of a bottleneck, for example a exit, using a parallel scheme leads to a longer congestion period and a more dispersive density distribution. The exit flow and the space-time distribution of density and velocity have significant discrepancies under four different update schemes when we simulate pedestrian flow with high desired velocity. Update schemes may have no influence on pedestrians in simulation to create tendency to follow others, but sequential and shuffled update scheme may enhance the effect of pedestrians' familiarity with environments.

  10. Use and generation of floor response spectra

    Ordonez Villalobos, A.

    1983-01-01

    One of the main objectives of the dynamic analysis of the structures of a nuclear power plant is the determination of the dynamic input that these structures transmit to the equipment and substructures they support, usually given as Floor Response Spectra (FRS). A close collaboration and feedback between the different groups that use and develop the FRS, is considered to be a very important factor in order to adapt the scope and content of the FRS to the precision required for a proper analysis or testing of the equipment; not only for the action of simple events but also for multiple combined actions. These aspects should be evaluated not only in the final stages of qualification of the equipment users schedules do not coincide with the schedules of the analysis group that develops the FRS. Different mechanisms of interchange of information and colaboration are suggested in order to optimize the availability, use and production of FRS. In the aspect of FRS generation, different procedures are reviewed including the direct procedures, not only for FRS but also for secondary FRS that are needed for the evaluation of equipment supported on other equipment or subsystems. It is concluded that in many cases, the direct procedures can be developed economically with the advantage that is easy to take into account the variability not only of the transfer function (including damping, stiffness and modal mass ratio). Different probabilities of excedence levels can be stabilized in order to obtain a more realistic dynamic response of the equipment. These last aspects can contribute to a more flexible procedure for the availability and generation of the FRS. (orig./HP)

  11. Functional levels of floor surface roughness for the prevention of slips and falls: clean-and-dry and soapsuds-covered wet surfaces.

    Kim, In-Ju; Hsiao, Hongwei; Simeonov, Peter

    2013-01-01

    Literature has shown a general trend that slip resistance performance improves with floor surface roughness. However, whether slip resistance properties are linearly correlated with surface topographies of the floors or what roughness levels are required for effective slip resistance performance still remain to be answered. This pilot study aimed to investigate slip resistance properties and identify functional levels of floor surface roughness for practical design applications in reducing the risk of slip and fall incidents. A theory model was proposed to characterize functional levels of surface roughness of floor surfaces by introducing a new concept of three distinctive zones. A series of dynamic friction tests were conducted using 3 shoes and 9 floor specimens under clean-and-dry as well as soapsuds-covered slippery wet environments. The results showed that all the tested floor-shoe combinations provided sufficient slip resistances performance under the clean-and-dry condition. A significant effect of floor type (surface roughness) on dynamic friction coefficient (DFC) was found in the soapsuds-covered wet condition. As compared to the surface roughness effects, the shoe-type effects were relatively small. Under the soapsuds-covered wet condition, floors with 50 μm in Ra roughness scale seemed to represent an upper bound in the functional range of floor surface roughness for slip resistance because further increase of surface roughness provided no additional benefit. A lower bound of the functional range for slip resistance under the soapsuds-covered wet condition was estimated from the requirement of DFC > 0.4 at Ra ≅ 17 μm. Findings from this study may have potential safety implications in the floor surface design for reducing slip and fall hazards. Published by Elsevier Ltd.

  12. PVC flooring at home and development of asthma among young children in Sweden, a 10-year follow-up.

    2014-06-01

    The incidence of asthma and allergy has increased throughout the developed world over the past decades. During the same period of time, the use of industrial chemicals such as phthalates, commonly used as plasticizers in polyvinylchloride (PVC) flooring material, has increased. The aim of this study was to investigate whether PVC flooring in the home of children in the age of 1-5 years is associated with the development of asthma in 5- and 10-year follow-up investigations (n = 3228). Dampness in Buildings and Health Study (DBH Study) commenced in 2000 in Värmland, Sweden. The current analyses included subjects who answered all baseline and follow-up questionnaires. Logistic regression analyses were applied to questionnaire results. Children who had PVC floorings in the bedroom at baseline were more likely to develop doctor-diagnosed asthma during the following 10-year period when compared with children living without. There were indications that PVC flooring in the parents' bedrooms was strongly associated with the new cases of doctor-diagnosed asthma when compared with child's bedroom. Our results suggest that PVC flooring exposure during pregnancy could be a critical period in the development of asthma in children at a later time; prenatal exposure and measurements of phthalate metabolites should be included in the future. This study has found that PVC flooring material in early life was related to incidence of asthma during the following 10 years when compared with other flooring materials and especially when comparing with wood flooring type.The study has further indicated that PVC flooring in the parents’ bedroom (proxy for prenatal exposure) was more associated with the development of asthma than PVC in the child’s bedroom was. Our results suggest that PVC flooring exposure during pregnancy could be a critical period in the development of asthma in children at a later time. In future prospective cohort study, prenatal exposure and measurements of

  13. THE FINANCIAL SETTLEMENT IN THE ENLARGEMENT OF THE EUROPEAN UNION: LESSONS FOR ROMANIA?

    Alan Mayhew

    2003-07-01

    Full Text Available At the end of every European Union accession negotiation, there is a fight about finance. Yet finance is by no means the most important element of the negotiations. Matters affecting the vital interests of new and old members like the free movement of labour or the representation of the new member state in the institutions of the Union are usually far more important in the longer term. But it is easier for politicians to talk to voters about money than about policy. The budgetary negotiations in this first enlargement to the countries of Central and Eastern Europe were perhaps more important in that these are relatively poor countries compared to the Union average per capita gross domestic product. They all will have to invest heavily in transport and environmental infrastructure in the coming decades in order to catch up with the standards of the EU-15 and support higher economic growth and development. Assuming responsible macro-economic policy in the new member states, EU budgetary transfers can speed up this investment process considerably, allowing these countries to catch up with the old member states in terms of per capita income more quickly. Higher transfers to the new member states means of course larger net budgetary contributions for the old member states (EU-15. This comes at a time when budget deficits are high and rising throughout the EURO-zone and when member states are making politically controversial cuts in social spending. The fiscal discipline involved in membership of the monetary union and implementation of the Broad Economic Policy Guidelines therefore means that the existing member states of the Union are not keen to see their net budgetary position with Brussels deteriorate or even their gross contributions to the budget rise. This paper investigates the background to the budget negotiations and the political economy behind them.

  14. Genetic Determinants of Metabolism and Benign Prostate Enlargement: Associations with Prostate Volume.

    Ayush Giri

    Full Text Available Prostate enlargement leading to clinical benign prostatic hyperplasia (BPH is associated with metabolic dysregulation and obesity. The genetic basis of this association is unclear. Our objective was to evaluate whether single nucleotide polymorphisms (SNPs previously associated with metabolic disorders are also associated with prostate volume (PV. Participants included 876 men referred for prostate biopsy and found to be prostate cancer free. PV was measured by transrectal ultrasound. Samples were genotyped using the Illumina Cardio-MetaboChip platform. Multivariable adjusted linear regression models were used to evaluate SNPs (additive coding in relation to natural-log transformed (log PV. We compared SNP-PV results from biopsy-negative men to 442 men with low-grade prostate cancer with similar levels of obesity and PV. Beta-coefficients from the discovery and replication samples were then aggregated with fixed effects inverse variance weighted meta-analysis. SNP rs11736129 (near the pseudo-gene LOC100131429 was significantly associated with log-PV (beta: 0.16, p-value 1.16x10(-8 after adjusting for multiple testing. Other noteworthy SNPs that were nominally associated (p-value < 1x10(-4 with log-PV included rs9583484 (intronic SNP in COL4A2, rs10146527 (intronic SNP in NRXN3, rs9909466 (SNP near RPL32P31, and rs2241606 (synonymous SNP in SLC12A7. We found several SNPs in metabolic loci associated with PV. Further studies are needed to confirm our results and elucidate the mechanism between these genetic loci, PV, and clinical BPH.

    Longstanding uncontrolled atherogenic risk factors may contribute to left atrial (LA) hypertension, LA enlargement (LAE) and coronary vascular dysfunction. Together they may better identify risk of major adverse cardiac events (MACE). The aim of this study was to test the hypothesis that chronic LA hypertension as assessed by LAE modifies the relationship between coronary vascular function and MACE. In 508 unselected subjects with a normal clinical {sup 82}Rb PET/CT, ejection fraction ≥40 %, no prior coronary artery disease, valve disease or atrial fibrillation, LAE was determined based on LA volumes estimated from the hybrid perfusion and CT transmission scan images and indexed to body surface area. Absolute myocardial blood flow and global coronary flow reserve (CFR) were calculated. Subjects were systematically followed-up for the primary end-point - MACE - a composite of all-cause death, myocardial infarction, hospitalization for heart failure, stroke, coronary artery disease progression or revascularization. During a median follow-up of 862 days, 65 of the subjects experienced a composite event. Compared with subjects with normal LA size, subjects with LAE showed significantly lower CFR (2.25 ± 0.83 vs. 1.95 ± 0.80, p = 0.01). LAE independently and incrementally predicted MACE even after accounting for clinical risk factors, medication use, stress left ventricular ejection fraction, stress left ventricular end-diastolic volume index and CFR (chi-squared statistic increased from 30.9 to 48.3; p = 0.001). Among subjects with normal CFR, those with LAE had significantly worse event-free survival (risk adjusted HR 5.4, 95 % CI 2.3 - 12.8, p < 0.0001). LAE and reduced CFR are related but distinct cardiovascular adaptations to atherogenic risk factors. LAE is a risk marker for MACE independent of clinical factors and left ventricular volumes; individuals with LAE may be at risk of MACE despite normal coronary vascular function. (orig.)

    2016-12-15

    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.)

  17. Muscle function of the pelvic floor in healthy, puerperal women with pelvic floor dysfunction.

    Castro-Pardiñas, M A; Torres-Lacomba, M; Navarro-Brazález, B

    2017-05-01

    To understand the function of the pelvic floor muscles (PFM) at different ages in healthy women and in puerperal women with pelvic floor dysfunctions (PFD) and to ascertain whether there are differences among them. A descriptive cross-sectional study was conducted between June 2014 and September 2016 and included 177 women, 70 of whom had no symptoms of PFD, 53 primiparous mothers in late postpartum and 54 with PFD. The function of the PFM was measured through vaginal palpation (quality of the contraction); manometry (force); dynamometer (tone, strength, and response to stretching), and surface electromyography (neuromuscular activity and resistance). The healthy women showed superior values for PFM tone, maximum strength, neuromuscular activity and resistance than the puerperal mothers and the women with PFD (P.05). The muscle function of the healthy women did not vary significantly with age, except in the case of tone, which was lower in the women older than 46 years (P=.004). Age and births decrease the baseline tone of the PFM in healthy women. Therefore, lower strength, resistance and neuromuscular activity appear to be the main difference between the PFM of women with PFD and the PFM of healthy women. Copyright © 2016 AEU.

  18. Physical and chemical test results of electrostatic safe flooring materials

    Gompf, R. H.

    1988-01-01

    This test program was initiated because a need existed at the Kennedy Space Center (KSC) to have this information readily available to the engineer who must make the choice of which electrostatic safe floor to use in a specific application. The information, however, should be of value throughout both the government and private industry in the selection of a floor covering material. Included are the test results of 18 floor covering materials which by test evaluation at KSC are considered electrostatically safe. Tests were done and/or the data compiled in the following areas: electrostatics, flammability, hypergolic compatibility, outgassing, floor type, material thickness, and available colors. Each section contains the test method used to gather the data and the test results.

  19. Stochastic seismic floor response analysis method for various damping systems

    Kitada, Y.; Hattori, K.; Ogata, M.; Kanda, J.

    1991-01-01

    A study using the stochastic seismic response analysis method which is applicable for the estimation of floor response spectra is carried out. It is pointed out as a shortcoming in this stochastic seismic response analysis method, that the method tends to overestimate floor response spectra for low damping systems, e.g. 1% of the critical damping ratio. An investigation on the cause of the shortcoming is carried out and a number of improvements in this method were also made to the original method by taking correlation of successive peaks in a response time history into account. The application of the improved method to a typical BWR reactor building is carried out. The resultant floor response spectra are compared with those obtained by deterministic time history analysis. Floor response spectra estimated by the improved method consistently cover the response spectra obtained by the time history analysis for various damping ratios. (orig.)

    Plessis, T.A. du; Badenhorst, F.

    1988-01-01

    Gamma radiation presents a unique method of transforming highly plasticized PVC floor tiles, manufactured at high speed through injection moulding, into a high quality floor covering at a cost at least 30% less than similarly rated rubber tiles. A specially formulated PVC compound was developed in collaboration with a leading manufacturer of floor tiles. These tiles are gamma crosslinked in its shipping cartons to form a dimensionally stable product which is highly fire resistant and inert to most chemicals and solvents. These crosslinked tiles are more flexible than the highly filled conventional PVC floor tiles, scratch resistant and have a longer lifespan and increased colour fastness. These tiles are also less expensive to install than conventional rubber tiles. (author)

    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

    To investigate the clinical application and efficacy of intradermal injection of low molecular weight hyaluronic acid (LMW-HA) for treating enlarged facial pores. 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.

    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

  6. Pelvic floor spasm as a cause of voiding dysfunction.

    Kuo, Tricia L C; Ng, L G; Chapple, Christopher R

    2015-07-01

    Pelvic floor disorders can present with lower urinary tract symptoms, bowel, sexual dysfunction, and/or pain. Symptoms of pelvic muscle spasm (nonrelaxing pelvic floor or hypertonicity) vary and can be difficult to recognize. This makes diagnosis and management of these disorders challenging. In this article, we review the current evidence on pelvic floor spasm and its association with voiding dysfunction. To distinguish between the different causes of voiding dysfunction, a video urodynamics study and/or electromyography is often required. Conservative measures include patient education, behavioral modifications, lifestyle changes, and pelvic floor rehabilitation/physical therapy. Disease-specific pelvic pain and pain from pelvic floor spasm needs to be differentiated and treated specifically. Trigger point massage and injections relieves pain in some patients. Botulinum toxin A, sacral neuromodulation, and acupuncture has been reported in the management of patients with refractory symptoms. Pelvic floor spasm and associated voiding problems are heterogeneous in their pathogenesis and are therefore often underrecognized and undertreated; it is therefore essential that a therapeutic strategy needs to be personalized to the individual patient's requirements. Therefore, careful evaluation and assessment of individuals using a multidisciplinary team approach including a trained physical therapist/nurse clinician is essential in the management of these patients.

    2003-01-01

    This paper describes the generation of floor time histories and corresponding floor response spectrums at various locations in reactor containment building (RCB) for 500 MWe Prototype Fast Breeder Reactor (PFBR). The RCB and its internal structures are modeled with equivalent 3D-beam elements (stick model), which have got the essential global stiffness and inertial properties of the corresponding building. The main aspect in the simulation of beam model is derivation of equivalent cross sectional properties such as bending, torsional and shear rigidities including shear centers. These properties have been obtained through 3D plate/shell element models with appropriate kinematic constraints, for the zones between floors of corresponding buildings. The stick model includes a set of springs and dampers to simulate soil effects, on which base raft and various sticks are mounted. The soil stiffness and damping values are derived based on equations given in ASCE-98. Time history analysis has been done using three uncorrelated time histories, which are derived from the site dependent design response spectra. Floor time histories (FTH) are extracted at important locations from which the corresponding floor response spectrums (FRS) have been generated for various damping values. Peak broadening of the response spectrums has been done according ASCE criteria. Floor response spectrum corresponds to reactor assembly support shows amplification 2.5 for SSE and 3 for OBE. CASTEM 3M is used for seismic analysis and generation of FRS. (author)

    Full Text Available This study was conducted with the objective of evaluating the use of concrete or hard-packed dirt floor in broiler houses. This experiment was carried out in two different phases. The following performance parameters were studied: live weight, feed intake, feed conversion ratio, and mortality. Litter moisture, pH and temperature were measured. Litter residual contamination after cleaning and disinfection was also evaluated. A dry bulb thermometer, a wet bulb thermometer, and a black bulb thermometer were placed inside each broiler house at bird height and outside the broiler house for data collection. Environmental data were collected at 3h intervals from 00:00 to 24:00 hours during weeks 4, 5, and 6 of the grow-out. Based on the collected data, air relative humidity (RH was determined, after which wet bulb globe temperature (WBGT and Radiant Heat Load (RHL were calculated. There were no differences in live performance parameters. However, total mortality and sudden death were higher in birds raised on dirt floor. On days 0, 14 and 35, litter pH was higher in the dirt floor as compared to the concrete floor, but at the end of the grow-out, this difference disappeared. There was a cubic effect of bird age on litter moisture, which increased up to day 28, and then stabilized or decreased. Litter coliform contamination was higher at the end of the grow-out as compared to that found at housing, but it was not influenced by floor type. The general thermal comfort of broiler raised on dirt floor was similar to that of broilers raised on concrete floor.

    Squamous cell carcinoma (SCC) of the oral tongue and floor of mouth are the most common head and neck cancers. Regional metastasis of SCC is most likely found at the cervical lymph node. Size and characteristics of pathologically suspicious lymph nodes are related to the aggressiveness of the primary tumor: The objective of this study is to analyze the conrrelation between sizes of cervical node and metastasis in SCC of oral tongue and floor of mouth. Retrospective review was conducted firom the patient's charts between January 2008 and December 2012. Clinical, histopathology and surgical records were reviewed. Cervical lymph nodes ofSCC of oral tongue and floor of mouth were reviewed and divided into four groups depending on their size (1-5 mm, 6-9 mm, 10-30 mm and more than 30 am,). A p-value oral cavity were recorded. Sixteen patients ofSCC of the oral tongue and 15patients of SCC of the floor of mouth underwent neck dissection (641 cervical nodes). Most ofthe patients were diagnosed with stage 3 (41.94%). Extracapsular extension was found in 72.15% of SCC of oral tongue and 73.33 % of SCC ofthe floor of mouth. Size of cervical lymph nodes less than 10 mm was found to be metastasis at 9.27% and 10.82% of SCC of oral tongue and floor of mouth, respectively. Cervical node metastasis can be found in SCC of the oral tongue and floor ofmouth with clinlically negative node andsize of cervical node less than 10 mm. Here in, size of cervical node less than 10 mm was still important due to the chance for metastasis especially high grade tumors, advanced stage cancer and lymphovascular invasion.

    -destructive resistivity drilling, and non-destructive georadar, and the results were compared. Floors were measured by 3D laser scanning technology and captured by the camera before reconstruction work. Using SFM photogrammetry were achieved results: ortomozaik (0.3 mm / pix) and DEM (0.6 mm / pix). These results were a basis for restoration work and also allow comparisons with the original state at any stage of the project. Drilling resistance measurement is used for indirect determination of strength profile based on resistance to drilling depending on into the depth. The observed resistance to drilling correlates with the strength and toughness of the measured material. The method is referred as a micro- or semi-invasive, since sampling is not necessary and but the drilling diameter is usually 3-5 mm. The ultrasonic measurement consists in the measuring of the longitude as well as the transverse waves - velocity, shape, amplitude. The propagation velocity is a characteristic values for the material influenced by its composition and compactness. Georadar (GPR) is a high frequency electromagnetic pulse method. For measurement the GPR RAMAC system coupled with 1600 MHz shielded antenna was used. Two tiles (one with defects and one in relatively good condition) were surveyed in a regular grid of perpendicular lines 5 cm separated. Data were processed by means of ReflexW software and performed in the form of cross sections and amplitude maps. The map of the amplitude summed over a time window 1 - 1,4 ns (representing the intensity of the reflection from the tiles bottom) gave good result. The areas of registered relatively high amplitudes correspond with the position of airgaps. A correlation was observed between the results of different survey methods.

  12. Patients with Pelvic Floor Muscle Spasm Have a Superior Response to Pelvic Floor Physical Therapy at Specialized Centers.

    2015-10-01

    Chronic prostatitis/chronic pelvic pain syndrome is a common condition that often requires multimodal therapy. Patients with chronic pelvic pain syndrome have a high incidence of pelvic floor spasm, which can be treated with pelvic floor physical therapy. However, this is a specialized skill. We compared outcomes of pelvic floor physical therapy as part of multimodal therapy in patients with chronic pelvic pain syndrome between those treated at our institution and elsewhere. We identified patients from our chronic pelvic pain syndrome registry with pelvic floor spasm who were seen between 2010 and 2014 for more than 1 visit. Patient phenotype was assessed with the UPOINT system and symptom severity was determined by the National Institutes of Health CPSI. A 6-point decrease in CPSI was used to define patient improvement. A total of 82 patients fit the study criteria. Mean age was 41.6 years (range 19 to 75) and median symptom duration was 24 months (range 3 to 240). Mean CPSI was 26.8 (range 10 to 41), the median number of positive UPOINT domains was 3 (range 1 to 6) and 27 patients (32.9%) were treated locally. At followup 9 patients had refused pelvic floor physical therapy, and 24 and 48 had undergone pelvic floor physical therapy elsewhere and at CCF, respectively. The mean change in CPSI was 1.11 ± 4.1 in patients who refused, -3.46 ± 6.7 in those treated elsewhere and -11.3 ± 7.0 in those treated at CCF (p physical therapy at CCF (OR 4.23, p = 0.002) and symptom duration (OR 0.52, p = 0.03) predicted improvement. Pelvic floor physical therapy can be effective for chronic pelvic pain syndrome in patients with pelvic floor spasm. However, the outcome depends on specialty training and experience of therapists.

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

    Pedersen, Peder J.; Pytlikova, Mariola

    In this paper we look at migration flows from 10 Central and Eastern European Countries (CEEC) to 5 Nordic countries over the years 1985 - 2007. We 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......, and Finland and Iceland from year 2006, the other Nordic countries chose a transition period in relation to the "new" EU members. The results based on a differences-in-differences estimator show that the estimated effect of the opening of the Swedish, Finnish and Icelandic labour markets on migration from...... the CEECs that entered the EU in 2004 is not significantly different from zero. However, the effect of the opening of the Swedish and Finnish labour markets in 2007 on migration from the 2007 EU entrants, Bulgaria and Romania, is significantly positive. Further, we are interested in the overall effect...

    Vijay Kumar Bokkasam

    2015-01-01

    Full Text Available Introduction: Panoramic radiograph is frequently prescribed by dentists for implant planning and, hence, accurate assessment of anatomical structures in panoramic radiograph is of utmost importance. Aims: The aim of the present study is to know the accuracy of panoramic radiograph in assessment of relationship between maxillary sinus floor and posterior teeth roots, and the distance from alveolar crest to nasal floor by comparing it with that of cone-beam computed tomographic (CBCT image. Materials and Methods: Panoramic and CBCT images of 30 patients were analyzed. The topographic relationship of each root of posterior teeth to the maxillary sinus floor was evaluated and classified into three classes. The distance from the peak point on maxillary alveolar crest to nasal floor was measured in panoramic radiograph as well as in CBCT image. All the measurements were made by built-in measurement tools. Results: Class 1 roots in panoramic radiograph showed high agreement (86% with CBCT image, followed by class 0 (76%. There was a significant difference in the measurements of alveolar bone height (ABH in the nasal floor region with a P value of 0.018. Conclusion: Panoramic radiograph is reliable in assessment of nasal floor and maxillary sinus, provided position of the patient, distortion, and the inherent magnification factor are taken into consideration.

    The feasibility of using an air gun near the sea floor as shear-wave source has been investigated. With an air gun near the sea floor, an evanescent P-wave in the water becomes a propagating S-wave in the sea floor, such that it seems that a pure shear-wave source has been used at the sea floor.

  20. Investigation into Mechanism of Floor Dynamic Rupture by Evolution Characteristics of Stress and Mine Tremors: A Case Study in Guojiahe Coal Mine, China

    Guangjian Liu

    2018-01-01

    Full Text Available In order to explore the mechanism of floor dynamic rupture, the current study adopts a thin plate model to further investigate the condition of floor failure. One of the possible explanations could be floor buckling due to high horizontal stress and dynamic disturbance ultimately leading to rapid and massive release of elastic energy thus inducing dynamic rupture. Seismic computed tomography and 3D location were employed to explore the evolution characteristics of floor stress distribution and positions of mine tremors. In the regions of floor dynamic rupture, higher P-wave velocity was recorded prior to the dynamic rupture. On the contrary, relatively lower reading was observed after the dynamic rupture thus depicting a high stress concentration condition. Meanwhile, evolution of mine tremors revealed the accumulation and subsequent release of energy during the dynamic rupture process. It was further revealed that dynamic rupture was induced due to the superposition of static and dynamic stresses: (i the high static stress concentration due to frontal and lateral abutment stress from coal pillar and (ii dynamic stress from the fracture and caving of coal pillar, hard roof, and key stratum. In the later part of this study, the floor dynamic rupture occurrence process would be reproduced through numerical simulations within a 0.6 sec time frame. The above-mentioned findings would be used to propose a feasible mechanism for prewarning and prevention of floor dynamic rupture using seismic computed tomography and mine tremors 3D location.
