  1. RISK ASSESSMENT PROCEDURE FOR CIVIL AIRPORT

    Directory of Open Access Journals (Sweden)

    Natalia Distefano

    2014-03-01

    Full Text Available A practical problem in air transport is how to manage risk and safety. In recent years have been developed special technical and managerial skills to the systematic, forward looking identification and control of hazards throughout the life cycle of a project, program, or activity. Safety Management System (SMS involves identifying, evaluating, and addressing of hazards or risk. Its sole purpose is to prevent accidents. Safety risk assessment is defined as the systematic identification and evaluation of the risk posed by the complete spectrum of possible accident scenarios. Risk assessment is a tool that supports decision making and as such supports risk management. Risk management comprises the safety optimization of the system, the verification process and risk acceptance, which support airport operations. This paper proposed a quantitative methodology for the risk assessment for a civil airport, which is based on historical data of aircraft accidents, contained in the Aviation Safety Network database, from 1 January 1980 to 31 December 2010.

Changes in pH value, moisture content, microflora and sugar content of cassava duringgari andfu-fu preparation are reported. Mannitol accumulated during thegari fermentation but not in either of thefu-fu fermentations. During each stage ofgari andfu-fu production, lactic acid bacteria predominated. Homofermentative organisms occurred most frequently in the early stages of each process and heterofermenters in the latter ones. Of the 179 microorganisms that were isolated and characterized fromgari andfu-fu, 52% were able to hydrolyse linamarin and 14% starch.

  4. Domestic violence assessment procedures among couple therapists.

    Science.gov (United States)

    Schacht, Rebecca L; Dimidjian, Sona; George, William H; Berns, Sara B

    2009-01-01

    Guidelines for addressing domestic violence (DV) in couple therapy have been published, but reports of whether therapists routinely follow these suggestions are few. A national survey of 620 couple therapists randomly selected from American Association for Marriage and Family Therapy members was conducted in 2000 to assess therapists' strategies for assessing DV and selecting a treatment modality when violence is discovered. Less than 4% of respondents indicated consistently following key published guidelines for DV screening (universal screening using separate interviews and questionnaires). A minority indicated that they consider the victim's safety as a factor in treatment modality selection. DV may be under-identified by couple therapists and therapists may be using conjoint therapy with couples for whom such therapy is contraindicated because of relationship violence.

  6. A simple procedure for preparing substrate for Pleurotus ostreatus cultivation.

    Science.gov (United States)

    Hernández, Daniel; Sánchez, José E; Yamasaki, Keiko

    2003-11-01

    The use of wooden crates for composting a mixture of 70% grass, (Digitaria decumbens), and 30% coffee pulp, combined with 2% Ca(OH)(2), was studied as a method for preparing substrate for the cultivation of Pleurotus ostreatus. Crate composting considerably modified the temperature pattern of the substrate in process, as compared to pile composting, where lower temperatures and less homogeneous distributions were observed. Biological efficiencies varied between 59.79% and 93% in the two harvests. Based on statistical analysis significant differences were observed between the treatments, composting times and in the interactions between these two factors. We concluded that it is possible to produce P. ostreatus on a lignocellulosic, non-composted, non-pasteurized substrate with an initial pH of 8.7, and that composting for two to three days improves the biological efficiency.

    O`Brien, D.A.; Bement, T.R.; Letellier, B.C.

    1993-11-01

    The purpose of this report is to describe the use of Probabilistic Risk (Safety) Assessment (PRA or PSA) at a Department of Energy (DOE) facility. PRA is a methodology for (i) identifying combinations of events that, if they occur, lead to accidents (ii) estimating the frequency of occurrence of each combination of events and (iii) estimating the consequences of each accident. Specifically the study focused on evaluating the risks associated with dissembling a hazardous assembly. The PRA for the operation included a detailed evaluation only for those potential accident sequences which could lead to significant off-site consequences and affect public health. The overall purpose of this study was to investigate the feasibility of establishing a risk-consequence goal for DOE operations.

  9. The preparation of patients taking anticoagulants for endoscopic procedures

    Directory of Open Access Journals (Sweden)

    Rafał Smoliński

    2016-12-01

    Full Text Available Drugs that inhibit platelet aggregation and  anticoagulants are widely used in  primary and  secondary prevention of thromboembolism and treatment of venous thrombosis. The use of these drugs is associated with an increased risk of bleeding during an endoscopic procedure, and their discontinuation leads to an increased risk of a thromboembolic event. The paper presents how to assess risk and how to prepare a patient treated with antiplatelet or anticoagulant drugs for endoscopic procedures. In each case, one should consider indications and planned duration of treatment as well as urgency of  the procedure. Diagnostic gastroscopy and  colonoscopy do  not usually require treatment modification, while the procedures with increased risk of bleeding require a change in therapy. In the case of antiplatelet drugs, it may be needed to stop it at a proper time before endoscopy. In the case of a dual antiplatelet therapy, when there are absolute indications for its use, one should consider postponing the procedure. Patients with increased risk of bleeding, treated with vitamin K antagonists, should have the treatment temporarily stopped and replaced with a bridging therapy with low molecular weight heparin; if the thromboembolic risk is assessed as low, a bridge therapy is not needed. The time to suspend the use of oral anticoagulants which are non-vitamin K antagonists depends on the risk of bleeding and renal function. Decisions concerning treatment may require consultation of a specialist ordering the anticoagulant or antiplatelet therapy as well as the opinion of an endoscopy centre in which the procedure is to be conducted. The doctor performing the examination should be informed about the treatment used by the patient and its modification.

  11. High velocity air microabrasion for conservative tooth preparation: the principle and the clinical procedure.

    Science.gov (United States)

    Feinman, R A

    1995-10-01

    Various technologies within the dental armamentarium are applied to achieve the precise tooth preparations required for the different types of restorations. This article reintroduces the air microabrasion technique, which was first presented in 1945. The popular use of this technique had been postponed, pending the decrease in cost and development of compatible restorative materials to repair the tooth structure. With increased patient demand for less invasive preparation techniques and the decrease of the equipment cost, the use of air microbrasion for tooth preparation has been recognized. The history of the technology, its function, indications, advantages, and limitations are discussed, and a step-by-step clinical procedure is presented. The learning objective of this article is to familiarize the readers with this preparation procedure, enhancing the knowledge of preparation options.

  15. From analogue to apps--developing an app to prepare children for medical imaging procedures.

    Science.gov (United States)

    Williams, Gigi; Greene, Siobhan

    2015-01-01

    The Royal Children's Hospital (RCH) in Melbourne has launched a world-first app for children that will help reduce anxiety and the need for anesthesia during medical imaging procedures. The free, game-based app, "Okee in Medical Imaging", helps children aged from four to eight years to prepare for all medical imaging procedures--X-ray, CT, MRI, ultrasound, nuclear medicine, and fluoroscopy. The app is designed to reduce anticipatory fear of imaging procedures, while helping to ensure that children attend imaging appointments equipped with the skills required for efficient and effective scans to be performed. This paper describes how the app was developed.

  16. Assessment of the MPACT Resonance Data Generation Procedure

    Kim, Kang Seog [Oak Ridge National Lab. (ORNL), Oak Ridge, TN (United States); Williams, Mark L. [Oak Ridge National Lab. (ORNL), Oak Ridge, TN (United States)

    2016-12-26

    Currently, heterogeneous models are being used to generate resonance self-shielded cross-section tables as a function of background cross sections for important nuclides such as 235U and 238U by performing the CENTRM (Continuous Energy Transport Model) slowing down calculation with the MOC (Method of Characteristics) spatial discretization and ESSM (Embedded Self-Shielding Method) calculations to obtain background cross sections. And then the resonance self-shielded cross section tables are converted into subgroup data which are to be used in estimating problem-dependent self-shielded cross sections in MPACT (Michigan Parallel Characteristics Transport Code). Although this procedure has been developed and thus resonance data have been generated and validated by benchmark calculations, assessment has never been performed to review if the resonance data are properly generated by the procedure and utilized in MPACT. This study focuses on assessing the procedure and a proper use in MPACT.

    2017-07-24

    The objective of this study was to describe the current practice regarding the preparation of the sedation-analgesia (SA) procedures performed in the paediatric emergency centres in Spain. A multicentre, observational and prospective analytical study was carried out on the SA procedures that were performed on children under 18 years-old in 18 paediatric emergency departments between February 2015 and January 2016. A total of 658 SA procedures were registered in 18 hospitals of Spain, most of them to children older than 24 months. The type of the procedure was: simple analgesia in 57 (8.6%), sedation in 44 (6.7%), SA for a not very painful procedure in 275 (41.8%), and SA for a very painful procedure in 282 (42.9%). Informed consent was requested in 98.6% of the cases. The written form was more frequently preferred in the group of patients that received SA for a very painful procedure (76.6%) in comparison to a painful procedure or to simple analgesia (62.9% and 54.4%, respectively, P<.001). The staff that most frequently performed the SA procedures were the paediatricians of the emergency departments (64.3%), followed by Paediatrics Residents (30.7%). The most frequent reasons for the SA were traumatological (35.9%) and surgical (28.4%). Fasting was observed in 81% of the cases. More than two-thirds (67.3%, n=480) children were monitored, the majority (95.8%) of them using pulse oximetry. The pharmacological strategy used was the administration of one drug in 443 (67.3%) of the cases, mostly nitrous oxide, and a combination of drugs in 215 (32.7%), especially midazolam/ketamine (46.9%). The majority of the SA procedures analysed in this study have been carried out correctly and prepared in accordance with the current guidelines. Copyright © 2017.

  3. Procedures used for assessment of stuttering frequency and stuttering duration.

    Science.gov (United States)

    Jani, Leanne; Huckvale, Mark; Howell, Peter

    2013-12-01

    Frequency of stuttered syllables and their durations were assessed using different procedures. The experiment examined overall syllable counts, counts of stuttered syllables and measures of stutter durations when they were made simultaneously or successively. Samples of speech with associated syllable, stuttered syllable and duration measurements of stuttering events were employed in reference transcriptions. Samples contained a minimum of 200 syllables. Ten participants assessed these samples for syllables, stuttered syllables and duration in an experiment. The responses of these participants were stored in alignment with the speech recordings for analysis. Performance was significantly more accurate (relative to transcriptions) for measures other than duration when the successive procedure was used as opposed to the simultaneous procedure. Although the successive method was more accurate, accuracy of stutter event identification was low for most participants. The procedure that allowed listeners to replay a speech sample and count the syllables, stuttered syllables and durations in three passes yielded more accurate syllable and stuttered syllable counts than procedures that required these judgments to be made in one pass.

  4. Improved Procedure for Preparation of Covalently Bonded Cellulose Tris-phenylcarbamate Chiral Stationary Phases

    秦峰; 陈小明; 刘月启; 邹汉法; 王俊德

    2005-01-01

    The classical method for preparation of covalently boned cellulose derivative chiral stationary phases (CSP) with diisocyanate as spacer was improved. Diisocyanate was firstly allowed to react with 3-aminopropyltriethoxysilane, and the resulting product was then applied as the spacer reagent to immobilize cellulose derivatives onto silica gel. Influences of the amount and the length of the spacer on the optical resolution ability of the CSP were investigated. Comparing improved procedure to classical diisocyanate method, the cross-linking between the glucose units of the cellulose derivatives was avoided to the most extent. With the improved procedure, regio-nonselective ways could be adooted to prepare covalently bonded CSP, which showed an advantage for the rapid preparation.

    Children with sickle cell disease (SCD) often undergo MRI studies to assess brain injury or to quantify hepatic iron. MRI requires the child to lie motionless for 30-60 min, thus sedation/anesthesia might be used to facilitate successful completion of exams, but this poses additional risks for SCD patients. To improve children's ability to cope with MRI examinations and avoid sedation, our institution established preparation and support procedures (PSP). To investigate the impact of PSP in reducing the need for sedation during MRI exams among children with SCD. Data on successful completion of MRI testing were compared among 5- to 12-year-olds who underwent brain MRI or liver R2*MRI with or without receiving PSP. Seventy-one children with SCD (median age 9.85 years, range 5.57-12.99 years) underwent a brain MRI (n = 60) or liver R2*MRI (n = 11). Children who received PSP were more likely to complete an interpretable MRI exam than those who did not 30 of 33; 91% vs. 27 of 38; 71%, unadjusted OR = 4.1 (P = 0.04) and OR = 8.5 (P < 0.01) when adjusting for age. PSP can help young children with SCD complete clinically interpretable, nonsedated MRI exams, avoiding the risks of sedation/anesthesia. (orig.)

    2005-01-01

    Full Text Available Background. Application of various technological procedures for the manufacture of officinal preparation ointment against chilblains (Unguentum contra perniones produce essential variations in the quality and stability of the final product. Changing the sequence of admixing active substances into the ointment base indicated the presence of incompatibility between the active substances, as well as between the active substances and the ointment base components. The aim was to examine the influence of various technological manufacturing procedures on quality and stability of the preparation. Methods. Changes in the samples of ointments and aqueous solutions of active substances were analyzed microscopically. Results. Microscopic analysis of hydrosoluble active substance solutions demonstrated destruction of ichthammol, induced by an acidic medium due to the dissolution of tannin and resorcinol, which is well known from the literature. It also demonstrated the destruction of tannin and resorcinol in aqueous solution, which had not been described in the literature. Application of the prescribed procedure for the manufacturing of ointment against chilblains, conceals the incompatibility reactions due to a slow dissolution of the tannin suspended in the officinal ointment base Unguentum cera lanae. Admixture of an ready-made aqueous solution of tannin caused an instant contact between ichthammol and the acidic medium, which caused the destruction or the complete absence of the formation of emulsion droplets. The problem of incompatibility reactions between lanolin alcohols in the ointment base and ichthammol and resorcinol, as well as the reaction between Peruvian balsam and sulfur from the ichthammol sulfate ion was observed. Numerous incompatibility reactions of ointment against chilblains, components indicated that it was necessary to introduce alterations in both the qualitative and quantitative composition of the preparation. Conclusion. Excipient

    The development of methods for rapid flood mapping and risk assessment is a key step to increase the usefulness of flood early warning systems and is crucial for effective emergency response and flood impact mitigation. Currently, flood early warning systems rarely include real-time components to assess potential impacts generated by forecasted flood events. To overcome this limitation, this study describes the benchmarking of an operational procedure for rapid flood risk assessment based on predictions issued by the European Flood Awareness System (EFAS). Daily streamflow forecasts produced for major European river networks are translated into event-based flood hazard maps using a large map catalogue derived from high-resolution hydrodynamic simulations. Flood hazard maps are then combined with exposure and vulnerability information, and the impacts of the forecasted flood events are evaluated in terms of flood-prone areas, economic damage and affected population, infrastructures and cities.An extensive testing of the operational procedure has been carried out by analysing the catastrophic floods of May 2014 in Bosnia-Herzegovina, Croatia and Serbia. The reliability of the flood mapping methodology is tested against satellite-based and report-based flood extent data, while modelled estimates of economic damage and affected population are compared against ground-based estimations. Finally, we evaluate the skill of risk estimates derived from EFAS flood forecasts with different lead times and combinations of probabilistic forecasts. Results highlight the potential of the real-time operational procedure in helping emergency response and management.

    Administered the Stanford-Binet and/or its downward extension the Cattell Infant Intelligence Scale to 22 children in a school for severely behaviorally disordered boys and girls. Assessments also were made with the Vineland Social Maturity Scale and with a scale of language development. A subgroup of 17 children were assessed with Rimland's E-2 Scale, which is designed to assess the presence and degree of the condition of autism. Correlations among these commonly used assessment procedures are reported. Findings are discussed with respect to the construct validity of the tests and with respect to practical problems of implementation. Issues that concern the distinctiveness of specific classification dimensions and the heterogeneity of the syndrome of autism also are discussed.

  13. Safety assessment of platform loadout procedures based on unascertained measures

    2007-01-01

    Safety assessment of offshore platforms is an urgent task. Such assessments are now focusing on the structure,maintenance, and retirement of a platform. Some methods employed have many shortcomings. For example, they cannot make the reliability adequately explicable. Therefore, a mathematical tool, the unascertained measure, was introduced. First, the basic knowledge of the unascertained sets was introduced briefly. Second, the unascertained measure was defined and credible identification was set up. The method has been introduced into the fields for safety assessment of a jacket loadout procedure.Engineering practices showed that it can complete the safety assessment systematically and scientifically without any assumption. The work should have significance in theory and practice for offshore engineering.

    For more than 30 years thin polyimide foils have been produced at IRMM by in-situ polymerisation. The procedure consists of three steps, all performed under ambient atmosphere: preparation of a polycondensate solution used to form foil by spreading on a glass plate, removal of the solvent by thermal treatment for 4 h at 100 °C and final polymerisation at high temperature (350 °C). Recently modifications of this procedure including preparation in an argon atmosphere and elimination of the time-consuming solvent removal were applied. The influence of these modifications on the quality of the foils was studied by testing the mechanical and thermal properties and the lifetime of the foil under a charged projectile beam. The influence of the modifications on the characteristics and on the level of impurities in the foils is presented as well. Comparative studies of parameters were performed for foils with an areal density between 20 and 80 μg cm -2. This work showed that the foils prepared by the new fast preparation manner in a dry atmosphere have the best properties for nuclear physics applications.

    Studies were conducted to determine the relative effectiveness of whole soak [current Bacteriological Analytical Manual-(BAM) Salmonella method], quarter, stomach, and blend methods for the recovery of Salmonella organisms from internally and externally contaminated tomatoes. Tomatoes were subjected to three inoculation methods: surface inoculation, internal inoculation by injection, and immersion with single Salmonella serovars. The inoculation levels ranged from 1 to 100 CFU/tomato for surface and injection inoculation or 1 to 100 CFU/mL for immersion inoculation. Tomatoes were held for 3 days after inoculation at 2-6 degrees C prior to initiation of analysis. Contaminated tomatoes were soaked, quartered, stomached, and blended in appropriate portions of Universal Pre-enrichment broth, and incubated for 24 h at 35 +/- 2 degrees C. The BAM Salmonella culture method was followed thereafter, and tomatoes were treated as a low-microbial-load food. The stomaching procedure was significantly (P < 0.05) more effective than the whole soak procedure for recovery of internalized Salmonella from tomatoes (by injection). The blending procedure was arithmetically superior to the stomaching procedure for detection of internalized Salmonella from tomatoes (by immersion). The blending procedure showed the same effectiveness as the whole soak procedure for the detection of Salmonella on tomato surfaces. Comparisons between test portion-to-broth ratios (weight to volume) showed that a 1:3 test portion-to-broth ratio had a better buffering capacity for blended tomatoes than a 1:1 test portion-to-broth ratio. It is recommended that the current whole soak BAM tomato sample preparation procedure be replaced with a blending procedure and a 1:3 test portion-to-broth ratio.

    Full Text Available In preparation of samples for chromatographic determination of ochratoxin A, two types of columns were used for sample cleanup (SPE and immunoaffinity columns. The first method consisted of liquid-liquid extraction with a mixture of chloroform and phosphoric acid, followed by ion-exchange cleanup on Waters Oasis MAX columns. The sec­ond method consisted of extraction with a mixture of water and methanol, followed by LCTech OtaCLEAN immunoaf­finity column cleanup. Recoveries of the methods were determined at three levels in three repetitions for maize flour, and they were 84% (%RSD = 19.2 for the first method of sample preparation and 101% (%RSD = 2.2 for the second method. Values of LOQ for OTA were 0.25 and 1.00 μg/kg for the IAC and SPE clean-up procedures, respectively. Both methods comply with present regulations, but the MAX sample clean-up procedure should be used as an alternative, since the immunoaffinity column clean-up procedure is characterized by better reproducibility, accuracy, and efficiency.

    The concern on climate change leads to growing demand for countermeasures against its impact on building performance. The aspects of building performance study includes the analysis of indoor thermal environment, building energy use, and energy efficiency design of building envelope. It enables and facilitates the evaluation of a building's performance during the design phase for adjusting the proposed architectural design to meet the expected performance criteria. The assessment of a building's performance is often done by hourly or sub-hourly computer dynamic simulation software with local weather datasets. These weather datasets, which are termed typical meteorological years (TMYs), are selected from long-term observed historical weather by means of Sandia method to ensure their representatives of local climate. Each TMY contains hourly values of observed data of a 1-year period. For the reason of longevous building lifespan and on-going climate change, one might ask how well the building is able to cope with future climate and what kind of countermeasure we should implement in advanced in face of climate change. However, the results obtained from the simulation with TMY couldn't forecast a building's performance in a future climate context without future climate is concerned. In this regard, future climate responsive meteorological data is needed for future climate impact study. From previous studies, as Belcher proposed, the future responsive weather data could be constructed by morphing existing TMY with future weather predicted by general circulation models (GCMs), which could substantially alleviate efforts from spatial and temporal downscaling processes. Consequently, choosing an adequate GCM that fits well with local climatic change pattern is in crucial need. The objective of the study is to develop a new GCMs selection method for generating future meteorological data. During TMY morphing procedure, monthly changes of a certain meteorological element in

    Nano-photocatalysis is becoming increasingly important due to its multiple applications and multidisciplinary aspects. Applications such as water/air purification, solar energy storage, chemicals production and optoelectronics are some of the most promising. In recent years, the development of novel environmental friendly and cost efficient methods for materials preparation that could replace the old ones is on demand. Unconventional and "soft" techniques such as sonication and photochemistry offer huge possibilities for the synthesis of a broad spectrum of nanostructured materials (e.g., nano-photocatalysts). In the present study, I focus on ultrasound and photochemical procedures for the preparation of nanostructured photocatalysts (e.g., supported metals, metal oxides) and their application in food organic wastes valorization.

    Ensuring the quality and reproducibility of results from biofilm structure and microbial community analysis is essential to membrane biofouling studies. This study evaluated the impacts of three sample preparation factors (ie number of buffer rinses, storage time at 4°C, and DNA extraction method) on the downstream analysis of nitrifying biofilms grown on ultrafiltration membranes. Both rinse and storage affected biofilm structure, as suggested by their strong correlation with total biovolume, biofilm thickness, roughness and the spatial distribution of EPS. Significant variations in DNA yields and microbial community diversity were also observed among samples treated by different rinses, storage and DNA extraction methods. For the tested biofilms, two rinses, no storage and DNA extraction with both mechanical and chemical cell lysis from attached biofilm were the optimal sample preparation procedures for obtaining accurate information about biofilm structure, EPS distribution and the microbial community. © 2014 © 2014 Taylor & Francis.

    This report discusses the simulant preparation procedure for producing multi-component simulants for leaching and filtration studies, including development and comparison activities in accordance with the test plan( ) prepared and approved in response to the Test Specification 24590-WTP-TSP-RT-06-006, Rev 0 (Smith 2006). A fundamental premise is that this approach would allow blending of the different components to simulate a wide variety of feeds to be treated in the Hanford Tank Waste Treatment and Immobilization Plant (WTP). For example, a given feed from the planned feed vector could be selected, and the appropriate components would then be blended to achieve a representation of that particular feed. Using the blending of component simulants allows the representation of a much broader spectrum of potential feeds to the Pretreatment Engineering Platform (PEP).

    2011-02-01

    A multifaceted radiochemical testing procedure has been developed to analyze a large number of liquid samples and measure a wide range of radionuclides in a short period of time. This method involves a single, unique and fast sample preparation procedure and allows sequential/concurrent determination of analytes with accuracy and precision. The same prepared sample can be selectively analyzed by gross alpha counting, gamma-ray spectroscopy, and alpha spectroscopy. This method is especially attractive in radiological emergency events where analytical data will be needed urgently as a basis for protective action. Given the simplicity and rapidity of the method, it may be suitable for field portable laboratories, which could save time and the cost associated with the transit of samples to a fixed laboratory. A 100 mL aliquot of sample was spiked with ¹³³Ba and ⁵⁹Fe tracers and subjected to a chemical separation procedure using a combined BaSO4 and Fe(OH)3 co-precipitation scheme. Then, the gross alpha-particle activity of the prepared sample was measured with a low-background gas-proportional counter, followed by the analysis of its photon-emitters using a gamma-ray spectroscopy system with high-purity intrinsic Ge detectors. Gamma-ray determination of ¹³³Ba and ⁵⁹Fe tracers was used to assess the chemical recoveries of BaSO4 and Fe(OH)3 fractions, respectively. Selectivity of the radionuclides for co-precipitation with either BaSO4 or Fe(OH)3 components was also investigated. Alpha mass-efficiency curves were derived using ²³⁰Th and ²⁴¹Am standards as alpha-calibration sources. Various mixtures of radionuclides, including ⁵⁴Mn, ⁵⁷Co, ⁶⁰Co, ⁸⁵Sr, ⁸⁸Y, ¹⁰⁹Cd, ¹¹³Sn, ¹³⁷Cs, ¹³⁹Ce, ²⁰³Hg, ²⁰⁹Po, ²²⁶Ra, ²²⁸Ra, ²³⁰Th, ²⁴¹Am, and natural uranium were used in this study. Most were quantitatively assayed with high chemical recoveries. Alpha-isotope identification and assessment of the prepared

    Mass spectrometry-based proteomics is a powerful analytical tool for investigating pathogens and their interactions within a host. The sensitivity of such analyses provides broad proteome characterization, but the sample-handling procedures must first be optimized to ensure compatibility with the technique and to maximize the dynamic range of detection. The decision-making process for determining optimal growth conditions, preparation methods, sample analysis methods, and data analysis techniques in our laboratory is discussed herein with consideration of the balance in sensitivity, specificity, and biomass losses during analysis of host-pathogen systems.

  11. Development of an Integrity Assessment Procedure for CANDU Pressure Tubes

    Energy Technology Data Exchange (ETDEWEB)

    Chung, Han Sub [Korea Electric Power Research Institute, Daejeon (Korea, Republic of)

    2010-10-15

    The pressure tubes used in a CANDU reactor are made from Zr-2.5Nb. During service the pressure tubes operate at temperatures between about 150 and 310 .deg. C, and with variable coolant pressures up to 11MPa corresponding to hoop stress of up to 130MPa. The maximum flux of fast neutrons (E>1MeV) from the fuel is about 4X10{sup 17}nm{sup -2}{sub s}{sup -1}. The pressure tubes are exposed to very severe degradation environment. The aging degradation of the pressure tubes are summarized as below. - Geometric deformation; axial elongation, diametric creep, and wall thinning. - Deuterium uptake; some fraction of the deuterium generated by the corrosion of pressure tubes is absorbed into the pressure tubes. Total equivalent hydrogen content in the pressure tube is the sum of the initial hydrogen content before operation and the deuterium uptake during operation. High concentration of hydrogen inside the pressure tubes makes the metal susceptible to Delayed Hydride Cracking. The DHC is a degradation mechanism of prime importance for CANDU pressure tubes. Mechanical properties, in particular fracture toughness, are deteriorated by high concentration of dissolved hydrogen. - Flaws; volumetric flaws are generated during operation. Wear scars by debris fretting, and bearing pad fretting are common. These volumetric flaws can be a site of crack initiation by fatigue or DHC. Cracks can propagate by DHC or fatigue crack propagation if conditions are met. - Material properties degradation; mechanical properties are affected by neutron irradiation. Yield strength and tensile strength are increased, and fracture toughness is deteriorated. The susceptibility to DHC is also affected. The integrity assessment of the pressure tube is a procedure to determine if the risk of pressure tube failure is controlled to maintain acceptably low. CSA N285.4 and 285.8 are two important guidelines regarding the integrity of pressure tubes. N285.4 is to guide in-service inspection, and N285

    Crouch gait deformity is common in children with cerebral palsy and often is associated with patella alta. Patellar tendon advancement typically is used to correct patella alta and restore normal knee mechanics. The purpose of this study was to determine the mechanical strength of surgical constructs used for fixation during patellar advancement procedures. This study used a cadaveric model to determine which of 3 surgical techniques is biomechanically optimal for patellar tendon advancement in treating patella alta. Twenty-four human cadaveric knees (8 per group) were prepared using 1 of 3 different common surgical techniques: tibial tubercle osteotomy, patellar tendon partial resection and repair at the distal patella, and patellar tendon imbrication. The patella was loaded from 25 to 250 N at 1 Hz for 1000 cycles. A significant difference in patella displacement under cyclical loading was found between surgical techniques. Tibial tubercle osteotomy exhibited significantly less displacement under cyclical loading than distal patella excision and repair (Ppatella excision and repair (P=.0006). Tibial tubercle osteotomy survived longest. Based on failure criteria of 5 mm of displacement, tibial tubercle osteotomy lasted between 250 and 500 cycles. The other 2 techniques failed by 25 cycles. This study offers quantitative evidence regarding the relative mechanical strength of each construct and may influence choice of surgical technique. [Orthopedics. 2016; 39(3):e492-e497.].

    2011-12-01

    Full Text Available The stability of amorphous aluminosilicate inorganic polymer (AIP systems with regard to the structural role of water molecules incorporated in inorganic matrix is discussed. Innovative approach to preparation of amorphous AIP systems with identical chemical composition but differing in structural and mechanical behavior is introduced. It is shown that even small changes in the manufacture dramatically affect mechanical properties and the overall structural stability of AIP systems. If the required quantity of water is admixed to the reaction mixture during the initial step of AIPs synthesis the resulting amorphous aluminosilicate matrix undergoes extensive crystallization (zeolitization. On the other hand, if the amount of water is added to the reaction mixture during the last step of the preparation procedure, the inorganic matrix exhibits long-term stability without any structural defects. To find the structural reasons of the observed behavior a combination of traditional solid state NMR (1H and 29Si MAS NMR, 29Si CP/MAS NMR, 29Si inverse-T1-filtered NMR, XRPD and TGA measurements were used. The applied experiments revealed that the structural stability of AIPs can be attributed to the tight binding of water molecules into the inorganic matrix. The structural stability of the prepared amorphous AIP systems thus seems to be affected by the extent of hydration i.e. the strength of binding water into the inorganic framework.

The study was undertaken to determine the influence of different pre-impression preparation procedures of antagonistic dental arch on the quality of the occlusal reproduction of the teeth in irreversible hydrocolloid impressions and to determine most reliable pre-impression preparation method to reduce the incidence of air bubbles. Materials and Methods: A total of 20 subjects were selected having full complement of mandibular teeth from second molar to second molar with well demarcated cusp height. 200 impressions were made with irreversible hydrocolloid material. The impressions were divided into five groups of 40 impressions each and each group had one specific type of pre-impression preparation. All the impressions were poured in die stone. A stereomicroscope with graduated eyepiece was used to count the number of bubbles on the occlusal surface of premolars and molars. The mean and standard deviations were calculated for each group. Mann–Whitney U-test was applied to find the significant difference between different groups. Results: Least bubbles were found in the group in which oral cavity was dried by saliva ejector and fluid hydrocolloid was finger painted onto the occlusal surfaces immediately before the placement of impression tray in the mouth. Conclusion: It was found that finger painting the tooth surfaces with fluid hydrocolloid immediately before the placement of loaded impression tray in the mouth was the most reliable method. The oral cavity can be cleared more easily of excess saliva by vacuum suction rather than by use of an astringent solution. PMID:26229376

    Full Text Available In the context of English language teaching, many studies that claimed to investigate teachers’ assessment practices were actually exploring their perceptions and belief with little reference to what they were practising in schools. The need to address such a limitation has prompted this study to examine the current formal assessment practices of English language teachers in lower secondary schools. Specifically, this paper reports how the teachers prepare the formal assessments. Extensive structured interviews were conducted with 72 teachers from 24 schools in Kuching division, Sarawak. Relevant documents such as test papers and assessment guidelines were also collected for further analysis. The findings from this study revealed that a majority of the teachers conducted formal assessments mainly due to the requirements of the school and ministry while following pre-determined steps in preparing a test. Furthermore, the findings also revealed teachers’ reliance on commercial reference books in constructing exam questions and sample answers. The outcome of the study provides an insight on the nature of English language teachers’ assessment practices in relation to the classroom teaching and learning at the secondary level.This could help inform the Ministry of Education in providing necessary support for the teachers particularly assessment practices in ESL context as well as in formulating a better assessment policy for schools.

  20. Preparative procedures markedly influence the appearance and structural integrity of protein storage vacuoles in soybean seeds.

    Krishnan, Hari B

    2008-05-14

    In legumes, vacuoles serve as the final depository for storage proteins. The protein storage vacuoles (PSVs) of soybean contain electron-transparent globoid regions in which phytic acid ( myo-inositol-1,2,3,4,5,6-hexakisphosphate) is sequestered. This paper reports the effect of preparative procedures on the appearance and ultrastructural integrity of PSVs in soybeans. Electron microscopy examination of both developing and mature soybean seeds that were postfixed with osmium tetroxide revealed PSVs that had a homogeneous appearance with very few globoid crystals dispersed in them. Numerous electron-dense lipid bodies were readily seen in these cells. Omission of osmium tetroxide strikingly altered the appearance of PSVs and aided the visualization of the location of the globoids in the PSVs. In contrast to the osmicated tissue, lipid bodies appeared as electron-transparent spheres. The choice of dehydration reagent or staining procedure had little influence on the appearance of the PSVs. The results of this study demonstrate the profound effect of osmium tetroxide on the appearance and structural integrity of PSVs in soybean.

  1. Influence of preparative procedures on the membrane viscoelasticity of human red cell ghosts.

    The effects of systematic variations in the preparative procedures on the membrane viscoelastic properties of resealed human red blood cell ghosts have been investigated. Ghosts, prepared by hypotonic lysis at 0 degrees C and resealing at 37 degrees C, were subjected to: measurement of the time constant for extensional recovery (tc); measurement of the membrane shear elastic modulus (mu) via three separate techniques; determination of the membrane viscosity (eta m) via a cone-plate Rheoscope. Membrane viscosity was also determined as eta m = mu X tc. Compared to intact cells, ghosts had shorter tc, regardless of their residual hemoglobin concentration (up to 21.6 g/dl). However, prolonged exposure to hypotonic media did increase their recovery time toward the intact cell value. The shear elastic modulus, as judged by micropipette aspiration of membrane tongues (mu p), was similar for all ghosts and intact cells. This result, taken with the tc data, indicates that ghosts have reduced membrane viscosity. Rheoscopic analysis also showed that eta m was reduced for ghosts, with the degree of reduction (approx. 50%) agreeing well with that estimated by the product mu p X tc. However, flow channel and pipette elongation estimates indicated that the ghost membrane elastic modulus was somewhat elevated compared to intact cells. We conclude that: ghosts have reduced membrane viscosity; ghosts have membrane rigidities close to intact cells, except possibly when the membrane is subjected to very large strains; the reduction in eta m is not directly related to the loss of hemoglobin; prolonged exposure of ghosts to low-ionic strength media increases the membrane viscosity toward its initial cellular level. These data indicate that the mechanical characteristics of ghost membranes can be varied by changing the methods of preparation and thus have potential application to further studies of the structural determinants of red cell membrane viscoelasticity.

    Full Text Available Dear editor:"n"nSwine flu is a new emerging atypical H1N1 influenza virus infection. Nowadays swine flu pandemic has become a global public health threat.1 As there are several epidemic foci of swine flu around the world and there are many infected cases, it is necessary for every country to prepare for management. Chest x-ray is an important investigation for the confirmed infected cases as well as highly suspicious cases. There must be specific concern for infection control in the procedure of patient preparation for chest x-ray. In routine clinical practice, separation of the patients and using specific isolated parts are suggested for general clinic; however, this might not be possible for the x-ray unit. It is routinely not possible to separate the x-ray room specifically for this group of patients. There must be a special communication system between the ward and the x-ray unit for early preparation. The process must be managed as a fast track procedure and preparation of a special room based on disinfectant principles before and after each x-ray procedure. In addition, preparation of the patients according to basic infection control process such as wearing masks and hand washing before the x-ray procedure are other precautionary measurements.

    The efficacy of chitosan-based hydrogels in the removal of dyes from aqueous solutions has been investigated as a function of different parameters. Hydrogels were obtained by gelation of chitosan with a non-toxic gelling agent based on an aqueous basic solution. The preparation procedure has been optimized in terms of chitosan concentration in the starting solution, gelling agent concentration and chitosan-to-gelling agent ratio. The goal is to properly select the material- and process-related parameters in order to optimize the performances of the chitosan-based dye adsorbent. First, the influence of such factors on the gelling process has been studied from a kinetic point of view. Then, the effects on the adsorption capacity and kinetics of the chitosan hydrogels obtained in different conditions have been investigated. A common food dye (Indigo Carmine) has been used for this purpose. Noticeably, although the disk-shaped hydrogels are in the bulk form, their adsorption capacity is comparable to that reported in the literature for films and beads. In addition, the bulk samples can be easily separated from the liquid phase after the adsorption process, which is highly attractive from a practical point of view. Compression tests reveal that the samples do not breakup even after relatively large compressive strains. The obtained results suggest that the fine tuning of the process parameters allows the production of mechanical resistant and highly adsorbing chitosan-based hydrogels.

    A major limitation for better understanding the role of the human gut virome in health and disease is the lack of validated methods that allow high throughput virome analysis. To overcome this, we evaluated the quantitative effect of homogenisation, centrifugation, filtration, chloroform treatment and random amplification on a mock-virome (containing nine highly diverse viruses) and a bacterial mock-community (containing four faecal bacterial species) using quantitative PCR and next-generation sequencing. This resulted in an optimised protocol that was able to recover all viruses present in the mock-virome and strongly alters the ratio of viral versus bacterial and 16S rRNA genetic material in favour of viruses (from 43.2% to 96.7% viral reads and from 47.6% to 0.19% bacterial reads). Furthermore, our study indicated that most of the currently used virome protocols, using small filter pores and/or stringent centrifugation conditions may have largely overlooked large viruses present in viromes. We propose NetoVIR (Novel enrichment technique of VIRomes), which allows for a fast, reproducible and high throughput sample preparation for viral metagenomics studies, introducing minimal bias. This procedure is optimised mainly for faecal samples, but with appropriate concentration steps can also be used for other sample types with lower initial viral loads.

    Full Text Available Tracey L Stierer,1,2 Nancy A Collop3,41Department of Anesthesiology, 2Department of Critical Care Medicine, Otolaryngology Head and Neck Surgery, Johns Hopkins Medicine, Baltimore, MD, USA; 3Department of Medicine, 4Department of Neurology, Emory University, Emory Sleep Center, Wesley Woods Center, Atlanta, GA, USAAbstract: With recent advances in surgical and anesthetic technique, there has been a growing emphasis on the delivery of care to patients undergoing ambulatory procedures of increasing complexity. Appropriate patient selection and meticulous preparation are vital to the provision of a safe, quality perioperative experience. It is not unusual for patients with complex medical histories and substantial systemic disease to be scheduled for discharge on the same day as their surgical procedure. The trend to “push the envelope” by triaging progressively sicker patients to ambulatory surgical facilities has resulted in a number of challenges for the anesthesia provider who will assume their care. It is well known that certain patient diseases are associated with increased perioperative risk. It is therefore important to define clinical factors that warrant more extensive testing of the patient and medical conditions that present a prohibitive risk for an adverse outcome. The preoperative assessment is an opportunity for the anesthesia provider to determine the status and stability of the patient’s health, provide preoperative education and instructions, and offer support and reassurance to the patient and the patient’s family members. Communication between the surgeon/proceduralist and the anesthesia provider is critical in achieving optimal outcome. A multifaceted approach is required when considering whether a specific patient will be best served having their procedure on an outpatient basis. Not only should the patient's comorbidities be stable and optimized, but details regarding the planned procedure and the resources available

    Full Text Available Background: Fear and pain are the factors producing stress and there is evidence that dental fear acquired in childhood may persist to influence adult behavior. Dental treatment is often considered as anxiety producing and stressful. Aim: To assess the levels of stress displayed by the healthy children undergoing routine dental procedures like oral examination, restoration, and extraction by analyzing salivary levels of cortisol before, during, and after the procedures. Materials and Methods: Twenty healthy children aged between 4 and 8 years having their first dental visit and requiring at least one restoration and one extraction were selected. In each patient, three procedures were carried out: (i Routine dental examination, (ii restoration, and (iii extraction. Unstimulated salivary samples were collected 10 min before, during the procedure, and 30 min after each procedure at three different visits for comparison of cortisol production in response to anxiety and stress over time. Total 180 samples were collected to determine salivary cortisol levels using UBI-MAGIWEL TM kit and the readings were noted. Statistical Analysis Used: Statistical Package for Social Sciences (SPSS software with paired t-test, two independent sample t-tests, and analysis of variance (ANOVA were used to analyze the findings. Results: A correlation between salivary cortisol and stress in dental procedure was noticed. Cavity preparation is more stressful procedure in children, so alternative methods can be used in anxious children. Stress associated with extraction persists to a postoperative period. No correlation exists in between Corah′s anxiety scale and salivary cortisol.

    2014-02-01

    Full Text Available It is generally accepted that interviewers have a considerable effect on survey response. The difference between response success and failure does not only affect the response rate, but can also influence the composition of the realized sample or respondent set, and consequently introduce nonresponse bias. To measure these two different aspects of the obtained sample, response propensities will be used. They have an aggregate mean and variance that can both be used to construct quality indicators for the obtained sample of respondents. As these propensities can also be measured on the interviewer level, this allows evaluation of the interviewer group and of the extent to which individual interviewers contribute to a biased respondent set. In this article, a procedure based on a multilevel model with random intercepts and random slopes is elaborated and illustrated. The results show that the procedure is informative to detect influential interviewers with an impact on nonresponse basis.

    Full Text Available Health was an element of general licensing procedures until Spain joined the EU in 1986, when the health report became diluted. The purpose of this article is to provide an overview of this topic’s current regulatory framework and to try to briefly describe health priorities and the channels for feasibly integrating the health variable in the environmental assessment of plans, programmes and projects from the public and private sectors. The current existence of the Environmental Assessment Act and the Public Health Act may help to achieve this.When preparing a strategic environmental study and an environmental impact study, the health impact assessment should be considered an essential step in these environmental procedures and have the same legal treatment as the “compulsory and determinant reports” of said procedures.Thus, it is concluded that the regulatory development of the aspects relating to the assessment of the health impact of the plans, programmes and projects envisaged in the Environmental Assessment Act is essential, the health impact assessment being the tool for doing so.

We investigated whether a psychological preparation through drama therapy and the therapeutic puppet may reduce the anxiety related to diagnostic and therapeutic procedures in the preschool or early school children suffering from cancer.Methods: Twenty consecutive pediatric patients of preschool and early school age, with the diagnosis of lymphoblastic leukemia, were included in the study. The patients were alternatingly assigned to experimental or control group, and subjected or not subjected to drama therapy, respectively. We measured the changes in heart rate, blood pressure and respiratory rate as indicators of anxiety and fear, before and after the diagnostic or therapeutic procedures.Results: Heart rate, blood pressure, and respiratory rate in pediatric oncological patients before and after the diagnostic or therapeutic procedure were significantly lower in the experimental group of patients.Conclusion: Our results show that psychological preparation using drama therapy and therapeutic puppet reduced the fear and anxiety related to diagnostic or therapeutic procedures in pediatric oncological patients.Key words: drama therapy; therapeutic puppet; children; oncology; psychology 

  20. Space Shuttle Meteoroid and Orbital Debris Threat Assessment Procedure

    Science.gov (United States)

    Hyde, J.; Christiansen, E.

    Prior to each shuttle mission, Meteoroid and orbital Debris (M/OD) threat assessments are performed to determine the critical penetration risk for the orbiter vehicle, the radiator tube leak risk &the window replacement risk. Mission parameters, such as vehicle attitude, exposure time and altitude are used as inputs for the assessment. The assessments are performed using the BUMPER computer code at the NASA/JSC Hypervelocity Impact Technology Facility (HITF). An M/OD risk analysis is typically performed in support of orbiter Cargo Integration Reviews (CIR) and Flight Readiness Reviews (FRR). Three types of M/OD risk are assessed. The most important involves the calculation of "critical" penetration risk, defined as penetrations that may result in the catastrophic loss of vehicle and crew. Critical failure criteria have been established though detailed engineering evaluations by NASA and Boeing. The radiator assessment is concerned with premature end-of- mission due to loss of a coolant loop. The window assessment is a postflight maintenance and logistics issue. The result s are provided to the Space Shuttle Vehicle Engineering Office (MV) the Space and Life Science Directorate (SA) at JSC. This paper will document the inputs used in the critical penetration analysis for CIR, FRR, and post-flight assessments, it will also serve as a reference for the Space Shuttle Orbiter finite element model (FEM) surface property definitions that are used in M/OD threat assessments.

    Full Text Available Abstract Background The intense pain and anxiety triggered by burns and their associated wound care procedures are well established in the literature. Non-pharmacological intervention is a critical component of total pain management protocols and is used as an adjunct to pharmacological analgesia. An example is virtual reality, which has been used effectively to dampen pain intensity and unpleasantness. Possible links or causal relationships between pain/anxiety/stress and burn wound healing have previously not been investigated. The purpose of this study is to investigate these relationships, specifically by determining if a newly developed multi-modal procedural preparation and distraction device (Ditto™ used during acute burn wound care procedures will reduce the pain and anxiety of a child and increase the rate of re-epithelialization. Methods/design Children (4 to 12 years with acute burn injuries presenting for their first dressing change will be randomly assigned to either the (1 Control group (standard distraction or (2 Ditto™ intervention group (receiving Ditto™, procedural preparation and Ditto™ distraction. It is intended that a minimum of 29 participants will be recruited for each treatment group. Repeated measures of pain intensity, anxiety, stress and healing will be taken at every dressing change until complete wound re-epithelialization. Further data collection will aid in determining patient satisfaction and cost effectiveness of the Ditto™ intervention, as well as its effect on speed of wound re-epithelialization. Discussion Results of this study will provide data on whether the disease process can be altered by reducing stress, pain and anxiety in the context of acute burn wounds.

    The past research reports in the area of safety engineering proposed the Computer-aided HAZOP system to be applied to Nuclear Reprocessing Facilities. Automated HAZOP system has great advantage compared with human analysts in terms of accuracy of the results, and time required to conduct HAZOP studies. This report surveys the literature on risk assessment and safety design based on the concept of independent protection layers (IPLs). Furthermore, to improve HAZOP System, tool is proposed to construct the basic model and the internal state model. Such HAZOP system is applied to analyze two kinds of processes, where the ability of the proposed system is verified. In addition, risk assessment support system is proposed to integrate safety design environment and assessment result to be used by other plants as well as to enable the underline plant to use other plants' information. This technique can be implemented using web-based safety information systems. (author)

    1987-07-01

    Incorporation of aesthetic considerations in the process of landscape planning and development has frequently met with poor results due to its lack of theoretical basis, public involvement, and failure to deal with spatial implications. This problem has been especially evident when dealing with large areas, for example, the Adirondacks, Scenic Highways, and National Forests and Parks. This study made use of public participation to evaluate scenic quality in a portion of the Niagara Escarpment in Southern Ontario, Canada. The results of this study were analyzed using the visual management model proposed by Brown and Itami (1982) as a means of assessing and evaluating scenic quality. The map analysis package formulated by Tomlin (1980) was then applied to this assessment for the purpose of spatial mapping of visual impact. The results of this study illustrate that it is possible to assess visual quality for landscape/management, preservation, and protection using a theoretical basis, public participation, and a systematic spatial mapping process.

The teat preparations included 'Iodine', 'Chlorhexidine' teat foam, 'Washing and drying' with paper, 'No preparation', 'Chlorine' teat foam, and disinfectant 'Wipes'. Teat preparations were applied for five days to 10 cows for each treatment during two herd management periods (indoors and outdoors. Teats were swabbed on day four and five before teat preparation and repeated after teat preparation. The swabs were plated on three selective agars: Baird Parker (Staphylococcus spp., Edwards (Streptococcus spp., and MacConkey (coliform. Following incubation, microbial counts for each pathogen type were manually counted and assigned to one of six categories depending on the microbial counts measured. The results were analysed by logistic regression using SAS 28. The main analysis was conducted on binary improvement scores for the swabbing outcomes. There were no differences for staphylococcal, streptococcal and coliform bacterial counts between treatments, measured 'before' teat preparation. Treatments containing 'Chlorhexidine' teat foam (OR = 4.46 and 'Wipes' (OR = 4.46 resulted in a significant reduction (P

    Double-Ended-Guillotine-Break(DEGB) in pipes can be prevented by detecting a leakage that occurs at the through-wall stage of a crack opening under those conditions. A consideration of these LBB characteristics can enlarge the degree of design freedom with respect to the materials, piping layouts, and safety measures against a leakage, thus leading to improved plant reliability and economy. For the LBB assessment of SFR pipes, creep crack growth could be considered, because SFRs are operated above 500 .deg. C. But the LBB assessment procedure for high temperature has not been established yet. In this study, we analyze RCC-MR A16 and propose procedure for the LBB assessment based on RCC-MR A16. For verification of this procedure, we conduct an example of LBB assessment. And we found partial procedure, equation and constant that has not been provided in RCC-MR A16. In this study, LBB assessment procedure has been proposed for SFRs design based on RCC-MR A16. Also, proposed procedure was verified by conducting an example assessment. As a result of those draw two conclusions as follow: · The LBB assessment of SFRs can be conducted by proposed procedure based on RCC-MR A16. · However, it is needed to develop determination of critical crack length methodology.

    2000-01-01

    Techniques for the in vitro 'reconstruction' of freshwater rainbow trout branchial epithelia using the primary culture of gill cells on permeable polyethylene terephthalate cell culture filter supports are described. Representing models of the freshwater fish gill, epithelia grown by two separate techniques are composed of branchial pavement cells with or without the inclusion of mitochondria-rich (MR) cells. The generation of epithelia consisting of pavement cells only (via a method called single seeded inserts = SSI) involves an initial period of flask culture during which time MR cells, that appear unable to attach to the culture flask base, are excluded from the general cell populace. Alternately, the generation of a heterogeneous epithelia consisting of both pavement cells and MR cells (via a method called double seeded inserts = DSI) is facilitated by the direct seeding of cells into cell culture filter inserts. Critical to this second procedure is the repeat seeding of filter inserts over a two day period. Repeat seeding appears to allow MR cells to nest amongst the attached cell layer generated by the first day's seeding. The use of cell culture filter supports allows free access to both the apical and basolateral compartment of the epithelium and is ideal for experimental manipulation. Cells are grown under symmetrical conditions (apical media/basolateral media) and epithelium growth is measured as a function of transepithelial resistance (TER). When the epithelia exhibit a plateau in growth they can be subjected to asymmetrical conditions (freshwater apical/media basolateral) in order to assess gill cell function as in vivo.

The results were analysed by logistic regression using SAS [28]. The main analysis was conducted on binary improvement scores for the swabbing outcomes. There were no differences for staphylococcal, streptococcal and coliform bacterial counts between treatments, measured 'before' teat preparation. Treatments containing 'Chlorhexidine' teat foam (OR = 4.46) and 'Wipes' (OR = 4.46) resulted in a significant reduction (P teats compared to 'Washing and drying' or 'No preparation'. 'Chlorine' teat foam (OR = 3.45) and 'Wipes' (3.45) had the highest probability (P disinfectant treatments applied in reducing coliforms. Thus, the use of some disinfectant products for pre-milking teat preparation can have beneficial effects on reducing the levels of staphylococcal and streptococcal pathogens on teat skin.

    Blirup-Jensen, S; Johnson, A M; Larsen, M

    2001-11-01

    A new approach for the assignment of values to serum proteins in a target material using a reference preparation has been developed. The procedure describes the general as well as the practical principles involved in the value assignment (with examples). Two models have been developed: 1) The direct value transfer between serum matrices and 2) the indirect value transfer from a pure protein preparation to a serum protein material. The necessary mathematical equations are developed and explained. The data reduction and statistical evaluation are discussed. The practical procedure (the transfer protocol) is based on six dilutions of the reference preparation assayed together with six dilutions of the target material. In this way imprecision is reduced and the proportionality of the two materials (i.e. the presence or absence of matrix effects) can be assessed directly by evaluating a single regression plot. If no matrix effects are found, the regression line will pass through zero with a slope equal to the ratio of the concentrations of the two materials. The transfer protocol is based on a multiple point value assignment obtained by several measurements a day repeated on several days, an important prerequisite being that all reconstitutions and dilutions are controlled by weighing.

  20. Using a learning needs assessment to identify knowledge deficits regarding procedural sedation for pediatric patients.

    Jest, Anne D; Tonge, Andrea

    2011-12-01

    Procedural sedation is a cost-effective method of providing sedation and analgesia for patients undergoing diagnostic and therapeutic procedures. Sedation ranges on a continuum from minimal sedation to deep sedation, so procedural sedation can pose many risks for patients (eg, compromised airway, depressed respirations, hypotension). The unique variables inherent in the pediatric population and the associated risks of procedural sedation make it imperative that RNs be knowledgeable and competent in monitoring and managing these patients. Through the use of a learning needs assessment, perioperative resource nurses at a pediatric hospital in a large, southeast metropolitan area identified practice concerns associated with staff RNs' management of pediatric patients undergoing procedural sedation. As a result of these findings, the perioperative resource nurses are in the process of implementing annual sedation competency skills testing in a special procedures laboratory for all nurses who participate in sedation procedures.

    OBJECTIVE:The stable quality of Chinese herbal medicines is a critical factor for their reliable clinical efficiency. An improved liquid-liquid extraction procedure and a liquid chromatographic method were developed to simultaneously analyze five anthraquinones (aloe-emodin, rhein, emodin, chrysophanol and physcion) in a Chinese traditional hospital preparation, Fuyankang mixture, in order to quantitatively control its quality in a more effective way. METHODS: A more economical and repeatable extraction procedure based on conventional liquid-liquid extraction technique was developed and used to extract ifve marker components in Fuyankang mixture. These anthraquinones were separated in less than 20 min on a C18 column with methanol and 0.1%phosphoric acid (88:12, v/v) as mobile phase. The method was validated for speciifcity, precision, spiked recovery and stability. RESULTS: Compared to conventional liquid-liquid extraction, the improved liquid-liquid extraction was found to be more effective for simultaneous extraction of anthraquinones from an aqueous Chinese herbal preparation, especially for hydrophobic compounds. The improved extraction method was successful y applied to determine the content of ifve marker components in Fuyankang mixture by the means of reverse phase high-performance liquid chromatography. CONCLUSION:The improved extraction procedure may be suitable for routine quality control of Fuyankang mixture and other traditional preparations at city-level hospitals in China.

    2006-05-01

    Full Text Available Abstract Background The ultimate goal of proteomic analysis of a cell compartment should be the exhaustive identification of resident proteins; excluding proteins from other cell compartments. Reaching such a goal closely depends on the reliability of the isolation procedure for the cell compartment of interest. Plant cell walls possess specific difficulties: (i the lack of a surrounding membrane may result in the loss of cell wall proteins (CWP during the isolation procedure, (ii polysaccharide networks of cellulose, hemicelluloses and pectins form potential traps for contaminants such as intracellular proteins. Several reported procedures to isolate cell walls for proteomic analyses led to the isolation of a high proportion (more than 50% of predicted intracellular proteins. Since isolated cell walls should hold secreted proteins, one can imagine alternative procedures to prepare cell walls containing a lower proportion of contaminant proteins. Results The rationales of several published procedures to isolate cell walls for proteomics were analyzed, with regard to the bioinformatic-predicted subcellular localization of the identified proteins. Critical steps were revealed: (i homogenization in low ionic strength acid buffer to retain CWP, (ii purification through increasing density cushions, (iii extensive washes with a low ionic strength acid buffer to retain CWP while removing as many cytosolic proteins as possible, and (iv absence of detergents. A new procedure was developed to prepare cell walls from etiolated hypocotyls of Arabidopsis thaliana. After salt extraction, a high proportion of proteins predicted to be secreted was released (73%, belonging to the same functional classes as proteins identified using previously described protocols. Finally, removal of intracellular proteins was obtained using detergents, but their amount represented less than 3% in mass of the total protein extract, based on protein quantification.

    Nowadays, low flow characteristics have been extensively studied for the design of hydrotechnical projects and water resources planning and management. Information on the magnitude and frequency of low flows is very important for hydrological drought analysis at operational level in public water supply systems. In this study, several low flow characteristics are derived and analysed for hydrological drought assessment at 26 watersheds located at Cevennes area, Southern France. The reliability of two statistical regionalisation techniques (the Principal Component Analysis and the L-moment approach) is tested on low flows characteristics for defining homogeneous regions in the study area and application of the methods to ungauged watersheds. The Threshold Level Method (TLM) is applied to estimate duration and deficit of the main hydrological drought events derived from flow duration curves at the study hydrometric stations using daily streamflow data for the period 1988 to 2008. Furthermore, the two regionalisation techniques are also applied in two other low flows indices, the annual minimum 7-days flow and the annual minimum 30-days flow. Finally, a regional analysis is performed in order to understand better the hydrological behavior of each watershed and the possible interactions between the hydrological regime and the descriptive hydrogeomorphologic characteristics.

  9. A probabilistic seismic risk assessment procedure for nuclear power plants: (I) Methodology

    2011-01-01

    A new procedure for probabilistic seismic risk assessment of nuclear power plants (NPPs) is proposed. This procedure modifies the current procedures using tools developed recently for performance-based earthquake engineering of buildings. The proposed procedure uses (a) response-based fragility curves to represent the capacity of structural and nonstructural components of NPPs, (b) nonlinear response-history analysis to characterize the demands on those components, and (c) Monte Carlo simulations to determine the damage state of the components. The use of response-rather than ground-motion-based fragility curves enables the curves to be independent of seismic hazard and closely related to component capacity. The use of Monte Carlo procedure enables the correlation in the responses of components to be directly included in the risk assessment. An example of the methodology is presented in a companion paper to demonstrate its use and provide the technical basis for aspects of the methodology. ?? 2011 Published by Elsevier B.V.

  10. Procedure for assessing the performance of a rockfall fragmentation model

    A Rockfall is a mass instability process frequently observed in road cuts, open pit mines and quarries, steep slopes and cliffs. It is frequently observed that the detached rock mass becomes fragmented when it impacts with the slope surface. The consideration of the fragmentation of the rockfall mass is critical for the calculation of block's trajectories and their impact energies, to further assess their potential to cause damage and design adequate preventive structures. We present here the performance of the RockGIS model. It is a GIS-Based tool that simulates stochastically the fragmentation of the rockfalls, based on a lumped mass approach. In RockGIS, the fragmentation initiates by the disaggregation of the detached rock mass through the pre-existing discontinuities just before the impact with the ground. An energy threshold is defined in order to determine whether the impacting blocks break or not. The distribution of the initial mass between a set of newly generated rock fragments is carried out stochastically following a power law. The trajectories of the new rock fragments are distributed within a cone. The model requires the calibration of both the runout of the resultant blocks and the spatial distribution of the volumes of fragments generated by breakage during their propagation. As this is a coupled process which is controlled by several parameters, a set of performance criteria to be met by the simulation have been defined. The criteria includes: position of the centre of gravity of the whole block distribution, histogram of the runout of the blocks, extent and boundaries of the young debris cover over the slope surface, lateral dispersion of trajectories, total number of blocks generated after fragmentation, volume distribution of the generated fragments, the number of blocks and volume passages past a reference line and the maximum runout distance Since the number of parameters to fit increases significantly when considering fragmentation, the

    Operating Room (OR) scheduling is crucial to allow efficient use of ORs. Currently, the predicted durations of surgical procedures are unreliable and the OR schedulers have to follow the progress of the procedures in order to update the daily planning accordingly. The OR schedulers often acquire the needed information through verbal communication with the OR staff, which causes undesired interruptions of the surgical process. The aim of this study was to develop a system that predicts in real-time the remaining procedure duration and to test this prediction system for reliability and usability in an OR. The prediction system was based on the activation pattern of one single piece of equipment, the electrosurgical device. The prediction system was tested during 21 laparoscopic cholecystectomies, in which the activation of the electrosurgical device was recorded and processed in real-time using pattern recognition methods. The remaining surgical procedure duration was estimated and the optimal timing to prepare the next patient for surgery was communicated to the OR staff. The mean absolute error was smaller for the prediction system (14 min) than for the OR staff (19 min). The OR staff doubted whether the prediction system could take all relevant factors into account but were positive about its potential to shorten waiting times for patients. The prediction system is a promising tool to automatically and objectively predict the remaining procedure duration, and thereby achieve optimal OR scheduling and streamline the patient flow from the nursing department to the OR.

However, this method suffers from the rough surface and excessively residual PbI{sub 2} in the resulting perovskite film, deteriorating the device performance seriously. Herein, a facial modified sequential solution deposition method, by introducing an as-prepared CH{sub 3}NH{sub 3}PbI{sub 3} and PbI{sub 2} film before the traditional two-step process, was proposed to fabricate the perovskite-based solar cell with smooth morphology and trace amount of remaining PbI{sub 2}. The optimal as-prepared film introduced improves the efficiency of CH{sub 3}NH{sub 3}PbI{sub 3} solar cells from 9.11% to 11.16%. The enhancement of device performance can be attributed to the increased light absorption ability and decreased recombination rate of carriers in CH{sub 3}NH{sub 3}PbI{sub 3} absorber.

  14. Glaucoma-inducing Procedure in an In Vivo Rat Model and Whole-mount Retina Preparation.

    Glaucoma is a disease of the central nervous system affecting retinal ganglion cells (RGCs). RGC axons making up the optic nerve carry visual input to the brain for visual perception. Damage to RGCs and their axons leads to vision loss and/or blindness. Although the specific cause of glaucoma is unknown, the primary risk factor for the disease is an elevated intraocular pressure. Glaucoma-inducing procedures in animal models are a valuable tool to researchers studying the mechanism of RGC death. Such information can lead to the development of effective neuroprotective treatments that could aid in the prevention of vision loss. The protocol in this paper describes a method of inducing glaucoma - like conditions in an in vivo rat model where 50 µl of 2 M hypertonic saline is injected into the episcleral venous plexus. Blanching of the vessels indicates successful injection. This procedure causes loss of RGCs to simulate glaucoma. One month following injection, animals are sacrificed and eyes are removed. Next, the cornea, lens, and vitreous are removed to make an eyecup. The retina is then peeled from the back of the eye and pinned onto sylgard dishes using cactus needles. At this point, neurons in the retina can be stained for analysis. Results from this lab show that approximately 25% of RGCs are lost within one month of the procedure when compared to internal controls. This procedure allows for quantitative analysis of retinal ganglion cell death in an in vivo rat glaucoma model.

Using the modified С10 plastination method, parasites from three different phylum were prepared: Plathelminthes: Class Cestoda (Dipilidum caninum, Moniezia spp and larvae from T.Echinococcus granulosus - Echinococcus unilocularis, larvae from T. pisiformis - Cysticercus pisiformis, , larvae from T. hidatigena - Cysticercus tenuicollis, Phylum Nemathelminthes, Class Nematoda, (Ascaris suum, Macracanthorhynchus hirudinaceus, Diro filaria immitis, Phylum Arthropoda, Class Arachnida (tick from the Ixodidae family and Class Insecta (Gasterophilus intestinalis, Hypoderma bovis. The aim of this study was conserving the parasites in native condition with plastination method and improved determination according to their visible morphologic structure. Parasites were previously kept in 10% formaldehyde. Prepared parasites were dry, chemical free, not toxic and safe for the environment, flexible and with detained form and structure. There was a variation in the natural colors in some of the parasites, as a result from long-time formalin fixation. Preparations made with this method are permanent educative material which enables improved study of parasite’s structure.

    To investigate the reliability and construct validity of procedure-based assessment (PBA) in assessing performance and progress in otolaryngology training. Retrospective database analysis using a national electronic database. We analyzed PBAs of otolaryngology trainees in North London from core trainees (CTs) to specialty trainees (STs). The tool contains six multi-item domains: consent, planning, preparation, exposure/closure, technique, and postoperative care, rated as "satisfactory" or "development required," in addition to an overall performance rating (pS) of 1 to 4. Individual domain score, overall calculated score (cS), and number of "development-required" items were calculated for each PBA. Receiver operating characteristic analysis helped determine sensitivity and specificity. There were 3,152 otolaryngology PBAs from 46 otolaryngology trainees analyzed. PBA reliability was high (Cronbach's α 0.899), and sensitivity approached 99%. cS correlated positively with pS and level in training (rs : +0.681 and +0.324, respectively). ST had higher cS and pS than CT (93% ± 0.6 and 3.2 ± 0.03 vs. 71% ± 3.1 and 2.3 ± 0.08, respectively; P otolaryngology trainees' performance and progress at all levels. It is highly sensitive in identifying competent trainees. The tool is used in a formative and feedback capacity. The technical domain is the best predictor and should be given close attention.

    Different instruments have been developed to improve crown finish lines after conventional preparation with diamond rotary instruments. However, more evidence on the effectiveness of these instruments is required. The purpose of this in vitro study was to assess the effectiveness of 4 different instruments used for cervical margin finishing in regard to the external line angle (ELA). Forty-eight freshly extracted third molar teeth with similar dimensions were conventionally prepared for crowns and randomly allocated into 4 groups (n=12) according to the finishing instrument: hand trimmer (HT), tungsten carbide bur (TCB), ultrasonic instrument (UI), and diamond rotary instrument (DRI) mounted in a contra angle handpiece with reduced speed. Photomicrographs from the margin profiles of each tooth were obtained with scanning electron microscopy (×40) before and after finishing procedures. The images were qualitatively analyzed (scores 1-4) by 9 experienced dental professionals. Average results were assessed with the paired t test and repeated measures ANOVA followed by Tukey HSD test (α=.05). HT, TCB, and UI demonstrated no significant differences between unfinished and finished mean ELA scores. DRI was the only group to demonstrate a significantly improved ELA (Pfinishing instrument capable of significantly improving the ELA, while TCB and UI produced nonsignificant improvement, and HT was detrimental to the ELA.

    SSM has supported research work for the further development of a previously developed procedure/handbook (SKI Report 99:49) for assessment of detected cracks and tolerance for defect analysis. During the operative use of the handbook it was identified needs to update the deterministic part of the procedure and to introduce a new probabilistic flaw evaluation procedure. Another identified need was a better description of the theoretical basis to the computer program. The principal aim of the project has been to update the deterministic part of the recently developed procedure and to introduce a new probabilistic flaw evaluation procedure. Other objectives of the project have been to validate the conservatism of the procedure, make the procedure well defined and easy to use and make the handbook that documents the procedure as complete as possible. The procedure/handbook and computer program ProSACC, Probabilistic Safety Assessment of Components with Cracks, has been extensively revised within this project. The major differences compared to the last revision are within the following areas: It is now possible to deal with a combination of deterministic and probabilistic data. It is possible to include J-controlled stable crack growth. The appendices on material data to be used for nuclear applications and on residual stresses are revised. A new deterministic safety evaluation system is included. The conservatism in the method for evaluation of the secondary stresses for ductile materials is reduced. A new geometry, a circular bar with a circumferential surface crack has been introduced. The results of this project will be of use to SSM in safety assessments of components with cracks and in assessments of the interval between the inspections of components in nuclear power plants

    The purpose of this study is to develop a tool to assess the procedural competence of radiology trainees, with sources of evidence gathered from five categories to support the construct validity of tool: content, response process, internal structure, relations to other variables, and consequences. A pilot form for assessing procedural competence among radiology residents, known as the RAD-Score tool, was developed by evaluating published literature and using a modified Delphi procedure involving a group of local content experts. The pilot version of the tool was tested by seven radiology department faculty members who evaluated procedures performed by 25 residents at one institution between October 2014 and June 2015. Residents were evaluated while performing multiple procedures in both clinical and simulation settings. The main outcome measure was the percentage of residents who were considered ready to perform procedures independently, with testing conducted to determine differences between levels of training. A total of 105 forms (for 52 procedures performed in a clinical setting and 53 procedures performed in a simulation setting) were collected for a variety of procedures (eight vascular or interventional, 42 body, 12 musculoskeletal, 23 chest, and 20 breast procedures). A statistically significant difference was noted in the percentage of trainees who were rated as being ready to perform a procedure independently (in postgraduate year [PGY] 2, 12% of residents; in PGY3, 61%; in PGY4, 85%; and in PGY5, 88%; p radiology trainees with high levels of construct validity in multiple domains. Implementation of the tool in the radiology residency curriculum is planned and can play an instrumental role in the transition to competency-based radiology training.

    Microlymphaticovenous anastomoses provide a potential for reducing lymphedema of the upper extremity complicating radical mastectomy or irradiation. Lymphoscintigraphy with technetium isotopes is a valuable investigative modality in the perioperative evaluation of patients undergoing this surgical procedure. The radionuclide studies provide information regarding structural change and physiologic derangement with a low radiation dose to the patient. It is a simple, painless procedure requiring minimal skill and no surgical intervention. In addition, a reproducible method for preparing a radiocolloid suitable for lymphatic imaging using an approved drug as a precursor has been developed.

    In this study, it has been demonstrated for the first time how sucrose gel-combustion could be used for the preparation of UO2 foam. Further the citrate gel-combustion was gainfully used for preparing porous pellets of UO2. The utility of two-step sintering (1073 K for 30 min and 1473 K for 4 h) for obtaining these porous bodies was demonstrated for the first time. The foams and pellets possessed meso and macro pores. A starting mixture with sucrose to nitrate ratio of 2.4 was found to yield urania foam with adequate crush strength. The porous pellets were found to possess better handling strength, lesser carbon residue and higher overall density than the foam. A citric acid to nitrate ratio 0.25 in the starting mixture, 180 MPa compaction pressure were optimal for obtaining a pellet with 40% porosity.

    Silver and gold organosols are easily prepared by transferring nanoparticles from aqueous phase into isooctane with high efficiency (>90%). Concentrations of sodium oleate and magnesium chloride have crucial effects on the transfer efficiency. Based on the UV-visible absorption spectra, TEM micrographs of nanoparticles, as well as molecular modeling calculation about the adsorption conformation of sodium oleate molecules, a possible phase transfer mechanism is proposed.

    Full Text Available Background: High stakes medical licensing programs are planning to augment and adapt current examinations to be relevant for a two-decision point model for licensure: entry into supervised practice and entry into unsupervised practice. Therefore, identifying which skills should be assessed at each decision point is critical for informing examination development, and gathering input from residency program directors is important. Methods: Using data from previously developed surveys and expert panels, a web-delivered survey was distributed to 3,443 residency program directors. For each of the 28 procedural and 18 advanced communication skills, program directors were asked which clinical skills should be assessed, by whom, when, and how. Descriptive statistics were collected, and Intraclass Correlations (ICC were conducted to determine consistency across different specialties. Results: Among 347 respondents, program directors reported that all advanced communication and some procedural tasks are important to assess. The following procedures were considered ‘important’ or ‘extremely important’ to assess: sterile technique (93.8%, advanced cardiovascular life support (ACLS (91.1%, basic life support (BLS (90.0%, interpretation of electrocardiogram (89.4% and blood gas (88.7%.

    While surgical site preparation has been extensively studied, there is little information about resistance of skin microbiota in the biofilm form to antimicrobial decontamination, and there are no quantitative models to study how biofilm might be transferred into sterile tissue/implant materials during injections for joint spine and tendon, aspiration biopsies and dermal fillers (DF). In this work, we develop two in vitro models to simulate the process of skin preparation and DF injection using pig skin and SimSkin (silicone) materials, respectively. Using the pig skin model, we tested three of the most common skin preparation wipes (alcohol, chlorhexidine and povidone iodine) and found that during wiping they reduced the biofilm bacterial burden of S. aureus (CFU cm−2) by three logs with no statistically significant differences between wipes. Using the SimSkin model, we found that transfer of viable bacteria increased with needle diameter for 30G, 25G and 18G needles. Transfer incidence decreased as injection depth was increased from 1 mm to 3 mm. Serial puncture and linear threading injection styles had similar transfer incidence, whereas fanning significantly increased transfer incidence. The results show that contamination of DF during injection is a risk that can be reduced by modifying skin prep and injection practices. PMID:28332593

    Roots of Pelargonium sidoides D.C. are used for the production of phytomedicines. Current quality control of phytopreparations containing P. sidoides extracts has been made in terms of total phenolics content. In this work we describe the development and validation of an HPLC method for the analysis of P. sidoides tincture and commercial syrup phytopreparations using umckalin (7-hydroxy-5,6-dimethoxycoumarin) as chemical marker. Two sample preparation procedures, liquid-liquid extraction (LLE) and solid-phase extraction (SPE) were also developed and compared. The samples were analyzed by RP-HPLC and the two methods were then validated and compared. The repeatability of the two procedures showed coefficients of variation (CV) of 1.2% for SPE procedure, and 1.3% for LLE. Recovery for both methods was higher than 95.2%. The linearity showed correlation coefficients better than 0.999 for both methods. The detection and quantification limit were 0.0098 and 0.0298microgmL(-1), respectively. The validated procedure was then used for the analysis of tincture and five batches of two commercial phytopreparations containing P. sidoides tincture.

    Flagging the individuals who did not answer consistently can be very useful in certain applied domains, especially in clinical and personnel selection areas. Identification of inconsistent patterns prevents erroneous interpretations of test scores. Two graphic procedures based on linear factor analysis are proposed in this paper. They allow the possible causes of low intra-individual consistency to be assessed once a pattern has been flagged as inconsistent. Moreover, these procedures allow us to identify the items that have contributed the most to the inconsistency. The procedures are illustrated with some empirical examples in personality. Lastly, implications of the results in the construction of personality measures are discussed.

Twenty-four one-rooted mandibular premolars were selected and randomly assigned to two groups. The samples (n = 12 of Group 1 were prepared using the ProTaper Universal rotary system, while Group 2 (n = 12 was prepared using the EndoEZE AET system complemented by manual apical preparation with K-type hand files up to #30. A 2.5% sodium hypochlorite solution was used in both groups for irrigating. Both groups were scanned by high-resolution microcomputed tomography before and after preparation (SkyScan 1172, SkyScan, Kontich, Belgium. The root canal volume and surface area was measured before and after preparation, and the differences were calculated and analyzed for statistically significant differences using ANOVA complemented by the Tukey test (p < 0.05. The results showed no statistically significant differences between the mean volumes of dentin removal by the two systems. However, the EndoEZE AET system presented a significantly greater mean surface area compared to the ProTaper system (p < 0.05. The EndoEZE AET system enabled preparation of a greater root canal surface area when compared to the ProTaper Universal system. There seemed to be no difference in dentin volume loss between the two systems used.

    The recording of human movement is an essential requirement for biomechanical, clinical, and occupational analysis, allowing assessment of postural variation, occupational risks, and preventive programs in physical therapy and rehabilitation. The flexible electrogoniometer (EGM), considered a reliable and accurate device, is used for dynamic recordings of different joints. Despite these advantages, the EGM is susceptible to measurement errors, known as crosstalk. There are two known types of crosstalk: crosstalk due to sensor rotation and inherent crosstalk. Correction procedures have been proposed to correct these errors; however no study has used both procedures in clinical measures for wrist movements with the aim to optimize the correction. To evaluate the effects of mathematical correction procedures on: 1) crosstalk due to forearm rotation, 2) inherent sensor crosstalk; and 3) the combination of these two procedures. 43 healthy subjects had their maximum range of motion of wrist flexion/extension and ulnar/radials deviation recorded by EGM. The results were analyzed descriptively, and procedures were compared by differences. There was no significant difference in measurements before and after the application of correction procedures (Pcorrection procedures were less than 5° in most cases, having little impact on the measurements. Considering the time-consuming data analysis, the specific technical knowledge involved, and the inefficient results, the correction procedures are not recommended for wrist recordings by EGM.

    This prospective cross-sectional study was undertaken to determine the frequency of procedural pain among 101 neonates in the first 14 days of admission to a neonatal intensive care unit (NICU) in South India and to study the perception of health-care professionals (HCP) about newborn procedural pain. The total number of painful procedures was 8.09 ± 5.53 per baby per day and 68.32 ± 64.78 per baby during hospital stay. The most common procedure was heel prick (30%). The HCP were administered a questionnaire to assess their perception of pain for various procedures. Procedures were perceived as more painful by nurses than by doctors. Chest tube placements and lumbar puncture were considered most painful. This study shows that the neonates in the NICU in developing countries experience many painful procedures. The awareness about this intensity of pain should provide a valuable tool in formulating pain-reduction protocols for management in low resource settings. © The Author [2014].

In isolated smooth muscle tissues taken from rats, rabbits and guinea-pigs, all at 37.5 degrees C, the equilibrium dissociation constant (K(beta)) of the competitive, reversible alpha-adrenoceptor antagonist phentolamine varied between 4 and 28 nm. 2. The concentration of the antagonist required to inhibit contractions to direct- or indirect-acting alpha-adrenenoceptor agonists by 50% (IC50) also varied between 5 and 30 nm. 3. From one tissue to another, the IC50/K(beta) ratio of the blocker varied from 1 to 2.5, the values being close to those predicted by classical receptor theory based on the law of mass action. 4. At 27.5 degrees C, using phenylephrine as the spasmogen in rat aorta, the IC50/K(beta) ratio for phentolamine was 3.1. 5. A significantly higher IC50 compared with K(beta) for phentolamine indicates that the procedures for estimating affinity constants for a competitive antagonist are not equivalent.

    An atmospheric pressure microwave digestion method has been developed for the combined analysis of total phosphorus and Kjeldahl nitrogen in complex matrices. In comparison to the digestion steps in EPA Methods 365.4 (total phosphorus) and 351.x (Kjeldahl nitrogen), this method requires less time, eliminates the need for a catalyst, and reduces the toxicity of the waste significantly. It employs a microwave-assisted digestion step, using refluxing borosilicate glass vessels at atmospheric pressure. Traditionally, this method has a time-consuming sample preparation step and generates toxic waste through the use of heavy metal catalysts. These advantages are gained by the combination of a high boiling point acid (sulfuric acid) and the application of focused microwave irradiation, which enhances the digestion process by direct energy coupling. NIST standard reference materials 1572 (citrus leaves), 1577a (bovine liver), and 1566 (oyster tissue) and tryptophan were analyzed to validate the method. Phosphorus concentrations were determined by the colorimetric ascorbic acid method outlined in EPA Method 365.3. Kjeldahl nitrogen concentrations were determined using EPA Method 351.1. The results of the analyses showed good precision and are in excellent agreement with the NIST published values for both elements.

    To develop a procedure specific global rating scale for assessment of operator competence in endovascular aortic repair (EVAR). A Delphi approach was used to achieve expert consensus. A panel of 32 international experts (median 300 EVAR procedures, range 200-3000) from vascular surgery (n = 21) and radiology (n = 11) was established. The first Delphi round was based on a review of endovascular skills assessment papers, stent graft instructions for use, and structured interviews. It led to a primary pool of 83 items that were formulated as global rating scale items with tentative anchors. Iterative Delphi rounds were executed. The panellists rated the importance of each item on a 5 point Likert scale. Consensus was defined as 80% of the panel rating an item 4 or 5 in the primary round and 90% in subsequent rounds. Consensus on the final assessment tool was defined as Cronbach's alpha > .8 after a minimum of three rounds. Thirty-two of 35 invited experts participated. Three rounds of surveys were completed with a completion rate of 100% in the first two rounds and 91% in round three. The 83 primary assessment items were supplemented with five items suggested by the panel and reduced to seven pivotal assessment items that reached consensus, Cronbach's alpha = 0.82. The seven item rating scale covers key elements of competence in EVAR stent placement and deployment. Each item has well defined grades with explicit anchors at unacceptable, acceptable, and superior performance on a 5 point Likert scale. The Delphi methodology allowed for international consensus on a new procedure specific global rating scale for assessment of competence in EVAR. The resulting scale, EndoVascular Aortic Repair Assessment of Technical Expertise (EVARATE), represents key elements in the procedure. EVARATE constitutes an assessment tool for providing structured feedback to endovascular operators in training. Copyright © 2017 European Society for Vascular Surgery. Published by Elsevier

    There are many models currently used for teaching and assessing performance of trauma-related airway, breathing, and hemorrhage procedures. Although many programs use live animal (live tissue [LT]) models, there is a congressional effort to transition to the use of nonanimal- based methods (i.e., simulators, cadavers) for military trainees. We examined the existing literature and compared the efficacy, acceptability, and validity of available models with a focus on comparing LT models with synthetic systems. Literature and Internet searches were conducted to examine current models for seven core trauma procedures. We identified 185 simulator systems. Evidence on acceptability and validity of models was sparse. We found only one underpowered study comparing the performance of learners after training on LT versus simulator models for tube thoracostomy and cricothyrotomy. There is insufficient data-driven evidence to distinguish superior validity of LT or any other model for training or assessment of critical trauma procedures.

  1. Assessment of a sequential phase extraction procedure for uranium-series isotope analysis of soils and sediments.

    2014-01-01

    The study of uranium-series (U-series) isotopes in soil and sediment materials has been proposed to quantify rates and timescales of soil production and sediment transport. Previous works have studied bulk soil or sediment material, which is a complex assemblage of primary and secondary minerals and organic compounds. However, the approach relies on the fractionation between U-series isotopes in primary minerals since they were liberated from the parent rock via weathering. In addition, secondary minerals and organic compounds have their own isotopic compositions such that the composition of the bulk material may not reflect that of primary minerals. Hence, there is a need for a sample preparation procedure that allows the isolation of primary minerals in soil or fluvial sediment samples. In this study, a sequential extraction procedure to separate primary minerals from soils and sediments was assessed. The procedure was applied to standard rock sample powders (TML-3 and BCR-2) to test whether it introduced any artefactual radioactive disequilibrium. A new step was introduced to remove the clay-sized fraction (extraction process to test how each step modifies the uranium-series activity ratios and mineralogy. Although no secondary minerals were detected in the unleached soil aliquots, the sequential leaching process removed up to 17% of U and Th and modified their activity ratios by up to 3%. The modification of the activity ratios poses a demand for careful means to avoid redistribution of isotopes back to the residual phase during phase extraction.

  2. A procedure for safety assessment of components with cracks - Handbook. 3rd revised edition

    Andersson, P.; Bergman, M.; Brickstad, B.; Dahlberg, L.; Nilsson, F.; Sattari-Far, I. [SAQ Kontroll AB, Stockholm (Sweden)

    1999-12-01

    In this handbook a procedure is described which can be used both for assessment of detected cracks or crack-like defects and for defect tolerance analysis. The procedure can be used to calculate possible crack growth due to fatigue or stress corrosion and to calculate the reserve margin for failure due to fracture and plastic collapse. For ductile materials, the procedure gives the reserve margin for initiation of stable crack growth. Thus, an extra reserve margin, unknown to size, exists for failure in components made of ductile materials. The procedure was developed for operative use with the following objectives in mind: a) The procedure should be able to handle both linear and non-linear problems without any a priori division. b) The procedure shall ensure uniqueness of the safety assessment. c) The procedure should be well defined and easy to use. d) The conservatism of the procedure should be well validated. e) The handbook, that documents the procedure, should be so complete that for most assessments, access to any other fracture mechanics literature should not be necessary. The method utilized in the procedure is based on the R6-method developed at Nuclear Electric plc. The basic assumption is that fracture initiated by a crack can be described by the variables K{sub r} and L{sub r}. K{sub r} is the ratio between the stress intensity factor and the fracture toughness of the material. L{sub r} is the ratio between applied load and the plastic limit load of the structure. The pair of calculated values of these variables is plotted in a diagram. If the point is situated within the noncritical region, fracture is assumed not to occur. If the point is situated outside the region, crack growth and fracture may occur. The method can in principal be used for all metallic materials. It is, however, more extensively verified for steel alloys only. The method is not intended for use in temperature regions where creep deformation is of importance. To fulfil the above

    2011-01-01

    This paper presents the procedures and results of intensity- and time-based seismic risk assessments of a sample nuclear power plant (NPP) to demonstrate the risk-assessment methodology proposed in its companion paper. The intensity-based assessments include three sets of sensitivity studies to identify the impact of the following factors on the seismic vulnerability of the sample NPP, namely: (1) the description of fragility curves for primary and secondary components of NPPs, (2) the number of simulations of NPP response required for risk assessment, and (3) the correlation in responses between NPP components. The time-based assessment is performed as a series of intensity-based assessments. The studies illustrate the utility of the response-based fragility curves and the inclusion of the correlation in the responses of NPP components directly in the risk computation. ?? 2011 Published by Elsevier B.V.

    1996-06-01

    Full Text Available A major problem in assessing macroseismic intensity from historical records is the lack of a standardized procedure for processing documentary sources and supplying unequivocal intensity estimates. In fact, most macroseismic, scales do not include detailed descriptions of procedures for intensity assessment and many divergent interpretations of intensity values arc obtained by different operators. In order to disclose these problems an experiment was made in Italy in 1994, in the framework of GNDT "Seismicity" Working Group. A set of selected documents concerning origil1al descriptions of effects produced by earthquakes which had occurred in Italy from 15th to 20th century, was supplied to a number of independent researchers. Each of them was invited to assess on this basis the intensity values and to explain his intellectual path by describing it in detail. This documentation was finally collected and, during a meeting devoted to this topic, the researchers involved were invited to discuss their personal experiences. The discussion indicated that the discrepancies between the estimate obtained by the different authors from the same documentary source are, in many cases, greater than 1 degree. This implies that the effect of personal choices may play an important role in intensity assessment and makes intensity estimates performed by the different authors less comparable. At present no definitive conclusions about these problems can be drawn but the topics focused during the meeting may represent a useful basis for a wider discussion to define a standardized procedure for thc assessment of intensity from documentary data.

    2015-01-01

    The second part of this article series presents an evidence-based update of clinical protocols and procedures for cavity preparation and restoration selection for bonded inlays and onlays. More than ever, tissue conservation dictates preparation concepts, even though some minimal dimensions still have to be considered for all restorative materials. In cases of severe bruxism or tooth fragilization, CAD/CAM composite resins or pressed CAD/CAM lithium disilicate glass ceramics are often recommended, although this choice relies mainly on scarce in vitro research as there is still a lack of medium- to long-term clinical evidence. The decision about whether or not to cover a cusp can only be made after a multifactorial analysis, which includes cavity dimensions and the resulting tooth biomechanical status, as well as occlusal and esthetic factors. The clinical impact of the modern treatment concepts that were outlined in the previous article - Dual Bonding (DB)/Immediate Dentin Sealing (IDS), Cavity Design Optimization (CDO), and Cervical Margins Relocation (CMR) - are described in detail in this article and discussed in light of existing clinical and scientific evidence for simpler, more predictable, and more durable results. Despite the wide choice of restorative materials (composite resin or ceramic) and techniques (classical or CAD/CAM), the cavity for an indirect restoration should meet five objective criteria before the impression.

    Full Text Available Complications of microocclusions have been reported after intra-arterial delivery of mesenchymal stromal cells. Hence, quantification and efficient limitation of cell clumps in suspension before transplantation is important to reduce the risk. We used a flow cytometry-based pulse-width assay to assess the effects of different cell suspension concentrations (0.2–2.0 × 106/mL, storage solutions (complete growth medium, Dulbecco’s phosphate-buffered saline, and normal saline, storage time in suspension (0–9 h, and freeze-thawing procedure on the clumping of rat bone marrow derived mesenchymal stromal cells (BMMSCs and also evaluated cell viability at the same time. Surprisingly, increasing the cell concentration did not result in more cell clumps in vitro. Freshly harvested (fresh cells in normal saline had significantly fewer cell clumps and also displayed high viability (>90%. A time-dependent reduction in viability was observed for cells in all three storage solutions, without any significant change in the clumping tendency except for cells in medium. Fresh cells were more viable than their frozen-thawed counterparts, and fresh cells in normal saline had fewer cell clumps. In conclusion, cell clumping and viability could be affected by different cell preparation procedures, and quantification of cell clumping can be conducted using the flow cytometry-based pulse-width assay before intra-arterial cell delivery.

    This study aims to assess the relevance of 1-point calibration procedure, within the framework of the development of a new telemetric temperature sensor. The criteria used for performance assessment were the level of accuracy, and the time of inertia of the temperature sensor prototype (TSP) tested. First, the stability of the calibration bath was assessed. Then, the accuracy of 16 prototypes was evaluated for 7 target temperatures (ranging from 29 °C to 45 °C). Finally, the inertia of TSP response was evaluated while increasing and decreasing the bath temperature. The difference between prototype and target temperature increases as bath temperature moves away from 37 °C; however, the accuracy of the sensor conforms to applicable standards. Most TSP remain in the range of ±0.2 °C for each temperature level tested, but a linear, decreasing slope is observed; prototypes underestimate high temperatures and overestimate low temperatures. Data from time of inertia assessment show that probes were within the range of ±0.2 °C from the target temperature with a maximal delay of 150 s which satisfy standard norms. However, results indicate that a 1-point calibration procedure of the sensors appears non optimal, a 2-point calibration procedure should be performed to avoid the observed temperature data slope.

    To determine whether geriatric triage decisions made using a comprehensive geriatric assessment (CGA) performed online are less reliable than face-to-face (FTF) decisions. Multisite noninferiority prospective cohort study. Two specialist geriatricians assessed individuals sequentially referred for an acute care geriatric consultation. Participants were allocated to one FTF assessment and an additional assessment (FTF or online (OL)), creating two groups-two FTF (FTF-FTF, n = 81) or online and FTF (OL-FTF, n = 85). Three acute care public hospitals in two Australian states. Admitted individuals referred for CGA. Nurse-administered CGA, based on the interRAI Acute Care assessment system accessed online and other online clinical data such as pathology results and imaging enabling geriatricians to review participants' information and provide input into their care from a distance. The primary decision subjected to this analysis was referral for permanent residential care. Geriatricians also recorded recommendations for referrals and variations for medication management and judgment regarding prognosis at discharge and after 3 months. Overall percentage agreement was 88% (n = 71) for the FTF-FTF group and 91% (n = 77) for the OL-FTF group. The difference in agreement between the FTF-FTF and OL-FTF groups was -3%, indicating that there was no difference between the methods of assessment. Judgements made regarding diagnoses of geriatric syndromes, medication management, and prognosis (with regard to hospital outcome and location at 3 months) were found to be equally reliable in each mode of consultation. Geriatric assessment performed online using a nurse-administered structured CGA system was no less reliable than conventional assessment in making clinical triage decisions. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics Society.

    2015-12-01

    Following publication of the National Academy of Sciences report "Strengthening Forensic Science in the United States: A Path Forward", there has been increasing interest in the application of multivariate statistical procedures for the evaluation of forensic evidence. However, prior to statistical analysis, variance from sources other than the sample must be minimized through application of data pretreatment procedures. This is necessary to ensure that subsequent statistical analysis of the data provides meaningful results. The purpose of this work was to evaluate the effect of pretreatment procedures on multivariate statistical analysis of chromatographic data obtained for a reference set of diesel fuels. Diesel was selected due to its chemical complexity and forensic relevance, both for fire debris and environmental forensic applications. Principal components analysis (PCA) was applied to the untreated chromatograms to assess association of replicates and discrimination among the different diesel samples. The chromatograms were then pretreated by sequentially applying the following procedures: background correction, smoothing, retention-time alignment, and normalization. The effect of each procedure on association and discrimination was evaluated based on the association of replicates in the PCA scores plot. For these data, background correction and smoothing offered minimal improvement, whereas alignment and normalization offered the greatest improvement in the association of replicates and discrimination among highly similar samples. Further, prior to pretreatment, the first principal component accounted for only non-sample sources of variance. Following pretreatment, these sources were minimized and the first principal component accounted for significant chemical differences among the diesel samples. These results highlight the need for pretreatment procedures and provide a metric to assess the effect of pretreatment on subsequent multivariate statistical

    2016-09-15

    We develop a procedure for assessing the environmental value of landscape mosaics that simultaneously considers the values of land use patches and the values of the boundaries between them. These boundaries indicate the ecological interactions between the patches. A landscape mosaic is defined as a set of patches and the boundaries between them and corresponds to a spatial pattern of ecological interactions. The procedure is performed in two steps: (i) an environmental assessment of land use patches by means of a function that integrates values based on the goods and services the patches provide, and (ii) an environmental valuation of mosaics using a function that integrates the environmental values of their patches and the types and frequencies of the boundaries between them. This procedure allows us to measure how changes in land uses or in their spatial arrangement cause variations in the environmental value of landscape mosaics and therefore in that of the whole landscape. The procedure was tested in the Sierra Norte of Madrid (central Spain). The results show that the environmental values of the landscape depend not only on the land use patches but also on the values associated with the pattern of the boundaries within the mosaics. The results also highlight the importance of the boundaries between land use patches as determinants of the goods and services provided by the landscape. Copyright © 2016 Elsevier Ltd.

    2011-01-01

    Full Text Available A damage assessment procedure has been developed using artificial neural network (ANN for prestressed concrete beams. The methodology had been formulated using the results obtained from an experimental study conducted in the laboratory. Prestressed concrete (PSC rectangular beams were cast, and pitting corrosion was introduced in the prestressing wires and was allowed to be snapped using accelerated corrosion process. Both static and dynamic tests were conducted to study the behaviour of perfect and damaged beams. The measured output from both static and dynamic tests was taken as input to train the neural network. Back propagation network was chosen for this purpose, which was written using the programming package MATLAB. The trained network was tested using separate test data obtained from the tests. A damage assessment procedure was developed using the trained network, it was validated using the data available in literature, and the outcome is presented in this paper.

    This report presents a limited assessment of the conservatism of the Accident Sequence Evaluation Program (ASEP) human reliability analysis (HRA) procedure described in NUREG/CR-4772. In particular, the, ASEP post-accident, post-diagnosis, nominal HRA procedure is assessed within the context of an individual`s performance of critical tasks on the simulator portion of requalification examinations administered to nuclear power plant operators. An assessment of the degree to which operator perforn:Lance during simulator examinations is an accurate reflection of operator performance during actual accident conditions was outside the scope of work for this project; therefore, no direct inference can be made from this report about such performance. The data for this study are derived from simulator examination reports from the NRC requalification examination cycle. A total of 4071 critical tasks were identified, of which 45 had been failed. The ASEP procedure was used to estimate human error probability (HEP) values for critical tasks, and the HEP results were compared with the failure rates observed in the examinations. The ASEP procedure was applied by PNL operator license examiners who supplemented the limited information in the examination reports with expert judgment based upon their extensive simulator examination experience. ASEP analyses were performed for a sample of 162 critical tasks selected randomly from the 4071, and the results were used to characterize the entire population. ASEP analyses were also performed for all of the 45 failed critical tasks. Two tests were performed to assess the bias of the ASEP HEPs compared with the data from the requalification examinations. The first compared the average of the ASEP HEP values with the fraction of the population actually failed and it found a statistically significant factor of two bias on the average.

    The development of real-time methods for rapid flood mapping and risk assessment is crucial to improve emergency response and mitigate flood impacts. This work describes the benchmarking of an operational procedure for rapid flood risk assessment based on the flood predictions issued by the European Flood Awareness System (EFAS). The daily forecasts produced for the major European river networks are translated into event-based flood hazard maps using a large map catalogue derived from high-resolution hydrodynamic simulations, based on the hydro-meteorological dataset of EFAS. Flood hazard maps are then combined with exposure and vulnerability information, and the impacts of the forecasted flood events are evaluated in near real-time in terms of flood prone areas, potential economic damage, affected population, infrastructures and cities. An extensive testing of the operational procedure is carried out using the catastrophic floods of May 2014 in Bosnia-Herzegovina, Croatia and Serbia. The reliability of the flood mapping methodology is tested against satellite-derived flood footprints, while ground-based estimations of economic damage and affected population is compared against modelled estimates. We evaluated the skill of flood hazard and risk estimations derived from EFAS flood forecasts with different lead times and combinations. The assessment includes a comparison of several alternative approaches to produce and present the information content, in order to meet the requests of EFAS users. The tests provided good results and showed the potential of the developed real-time operational procedure in helping emergency response and management.

  1. Determination of gross alpha, 224Ra, 226Ra, and 228Ra activities in drinking water using a single sample preparation procedure.

    2005-12-01

    The current federal and New Jersey State regulations have greatly increased the number of gross alpha and radium tests for public and private drinking water supplies. The determination of radium isotopes in water generally involves lengthy and complicated processes. In this study, a new approach is presented for the determination of gross alpha, 224Ra, 226Ra, and 228Ra activities in water samples. The method includes a single sample preparation procedure followed by alpha counting and gamma-ray spectroscopy. The sample preparation technique incorporates an EPA-approved co-precipitation methodology for gross alpha determination with a few alterations and improvements. Using 3-L aliquots of sample, spiked with 133Ba tracer, the alpha-emitting radionuclides are isolated by a BaSO4 and Fe(OH)3 co-precipitation scheme. First the gross alpha-particle activity of the sample is measured with a low-background gas-flow proportional counter, followed by radium isotopes assay by gamma-ray spectroscopy, using the same prepared sample. Gamma-ray determination of 133Ba tracer is used to assess the radium chemical recovery. The 224Ra, 226Ra, and 228Ra activities in the sample are measured through their gamma-ray-emitting decay products, 212Pb, 214Pb/214Bi, and 228Ac, respectively. In cases where 224Ra determination is required, the gamma-ray counting should be performed within 2-4 d from sample collection. To measure 226Ra activity in the sample, the gamma-ray spectroscopy can be repeated 21 d after sample preparation to ensure that 226Ra and its progeny have reached the equilibrium state. At this point, the 228Ac equilibration with parent 228Ra is already established. Analysis of aliquots of de-ionized water spiked with NIST-traceable 230Th, 224Ra, 226Ra, and 228Ra standards demonstrated the accuracy and precision of this method. Various performance evaluation samples were also assayed for gross alpha as well as radium isotope activity determination using this procedure and the

    The purpose of this study was to evaluate cardiovascular parameters during dental procedures: systolic, diastolic, and mean blood pressures, and heart rate. Nineteen healthy normotensive patients (18-56 years of age) received restorative treatment on three maxillary molars. The patients were continuously monitored by a non-invasive automatic monitor for blood pressure and heart rate during the pre-, trans-, and post-operative periods at the following stages: 15 min prior to anesthesia; during topical anesthesia; during infiltrative anesthesia; for 5 minutes immediately after; during cavity preparation; during restorative procedure; for 10 min after completion. Patients were divided into three groups: A (without pre-medication), B (preceded by 10 mg diazepam), and C (preceded by placebo). All patients received infiltrative anesthesia containing 1.8 mL of 2% lidocaine (36 mg) with epinephrine 1:100,000 (18 microg). There were no changes in the parameters during the clinical procedures. When groups were compared, there were significant differences in diastolic arterial pressures during anesthesia.

  6. Emedastine and allergic conjunctivitis: new preparation. Poor assessment.

    Science.gov (United States)

    2001-04-01

    (1) There is no clearly established reference eye-drop preparation for the treatment of allergic conjunctivitis. Steroid eye drops must be avoided. Virtually the only criterion on which to base the choice among the other antiallergic eye drops is the type and presence of preservatives, as these must be avoided by the small number of patients who are allergic to them. (2) In our opinion the clinical file on the 0.05% emedastine eye drops now available in France fails to answer many practical questions, as it almost solely comprises single-dose clinical pharmacology studies. (3) A trial involving 221 patients with allergic conjunctivitis, during a period of pollination, showed no tangible difference in efficacy between 0.05% emedastine and 0.05% levocabastine eye drops after 6 weeks of treatment. (4) The main adverse effects observed in clinical trials were local, consisting of eye redness, dryness and discomfort. When taken orally, emedastine is known to prolong the QT interval, and it is difficult to determine the precise cardiac risk during ocular administration. (5) 0.05% emedastine eye drops change nothing in the management of allergic conjunctivitis.

    Mass spectrometry (MS) techniques are commonly used for protein identification and further analysis of selected protein spots after high resolution 2-D electrophoresis. Complementary gel-free approaches have been developed during the last few years and have shown to be useful tools in modern proteomics. The development and application of various gel-free electrophoresis devices for performing protein fractionation according to the pI differences is therefore a topic of interest. This review describes the current state of isoelectric focusing (IEF) gel-free electrophoresis based on the Agilent offgel 3100 fractionator. The review includes, therefore, (i) an overview on IEF as well as other previous IEF gel-free electrophoresis developments; (ii) offgel fundamentals and future trends; (iii) advantages and disadvantages of current offgel procedures; (iv) requirements of isolated protein pellets for further offgel fractionation; (v) offgel fraction requirements to perform the second dimensional analysis by advance electrophoresis and chromatographic techniques; and (vi) effect of the offgel operating conditions on the stability of metal-protein complexes.

  9. Patient assessment: preparing for a predictable aesthetic outcome.

    2015-01-01

    The flux of patients seeking to make changes to the appearance of their smile zone appears to be on a pathway of continual increase. This is possibly due to an increase in awareness towards oral health, and perhaps social, peer and media pressures, respectively. Cohorts of dental practitioners have thus responded to the latter demands by attending a plethora of educational courses, often focusing on either restorative techniques or other disciplines, notably orthodontics and clear aligners in particular. Consequently, treatment planning and thus treatment provision may carry the risk of being biased or indeed 'outcome driven' whereby the skills and knowledge of any clinician towards a particular faculty may significantly influence the ultimate treatment plan, with the unfortunate tendency sometimes to overlook the role of the interdisciplinary approach of concomitant restorative and contemporary techniques. The role of orthodontics to facilitate the provision of such treatment, along with predictable enamel bonding, has the distinct advantage of providing an acceptable aesthetic result with minimal biological intervention. However, to achieve an optimal result in such cases requires meticulous treatment planning and patient selection to avoid pitfalls with regards to long-term stability and function. This article suggests a standardized approach to patient assessment, with an interdisciplinary perspective in mind. Clinical Relevance: With the growth of patient demand for improving the appearance of the smile, a meticulous assessment protocol is required along with effective interdisciplinary communication. This enables a comprehensive treatment plan to be developed with the correct priorities.

    Composites are prepared by deposition of nanoparticles of RuO{sub 2}.xH{sub 2}O (1-4 nm) on two carbons: microporous carbon (1.3 nm of average micropore size) and mesoporous carbon (11 nm of average mesopore size). Two-preparation procedures are used: (i) procedure A consisting of repetitive impregnations of the carbons with RuCl{sub 3}.0.5H{sub 2}O solutions, and (ii) procedure B based on impregnation of the carbons with Ru(acac){sub 3} vapour. The procedure B leads to supported RuO{sub 2}.xH{sub 2}O particles that appear more crystalline than those obtained by the procedure A. Specific capacitance and specific surface area of the composites are discussed as functions of the RuO{sub 2} content, and different dependences for the composites derived from the two carbons are found. Mesoporous carbon is better support than microporous carbon. Procedure A leads to supported RuO{sub 2}.xH{sub 2}O particles with higher specific capacitance than the particles deposited by procedure B.

    2015-01-01

    Background High quality of informed consent form is essential for adequate information transfer between physicians and patients. Current status of medical procedure consent forms in clinical practice in Croatia specifically in terms of the readability and the content is unknown. The aim of this study was to assess the readability and the content of informed consent forms for diagnostic and therapeutic procedures used with patients in Croatia. Methods 52 informed consent forms from six Croatian hospitals on the secondary and tertiary health-care level were tested for reading difficulty using Simple Measure of Gobbledygook (SMOG) formula adjusted for Croatian language and for qualitative analysis of the content. Results The averaged SMOG grade of analyzed informed consent forms was 13.25 (SD 1.59, range 10–19). Content analysis revealed that informed consent forms included description of risks in 96% of the cases, benefits in 81%, description of procedures in 78%, alternatives in 52%, risks and benefits of alternatives in 17% and risks and benefits of not receiving treatment or undergoing procedures in 13%. Conclusions Readability of evaluated informed consent forms is not appropriate for the general population in Croatia. The content of the forms failed to include in high proportion of the cases description of alternatives, risks and benefits of alternatives, as well as risks and benefits of not receiving treatments or undergoing procedures. Data obtained from this research could help in development and improvement of informed consent forms in Croatia especially now when Croatian hospitals are undergoing the process of accreditation.

  14. A real-world application of Monte Carlo procedure for debris flow risk assessment

    Science.gov (United States)

    Calvo, B.; Savi, F.

    2009-05-01

    A method for formal risk analysis in debris flow-prone areas is proposed. In this paper risk is defined as the mean annual probability for buildings located in hazardous areas to be damaged by a debris flow. As is well known, specific risk assessment involves the evaluation of both hazard and vulnerability. To quantify debris flow hazard, a Monte Carlo procedure is applied that randomly selects the input variables of mathematical models simulating triggering, propagation and stoppage of debris flows. This allows to estimate the probability density function of the output variables characterizing the destructive power of debris flow (for instance total force, sum of hydrostatic and hydrodynamic forces) at each point of the alluvial fan. Three different vulnerability functions are adopted: two of them are derived from assessments of different types of natural risk, such as snow avalanches and flood waves. The third vulnerability function is obtained from structural analysis of buildings damaged during a mudflow that occurred in Sarno, Italy. The proposed procedure is applied to assess specific risk on the alluvial fan of Ardenno, located in the Valtellina valley, Italian Alps, and the effect that the use of different vulnerability functions has on the risk maps is explored and discussed.

    To evaluate the frequency of dentinal micro-cracks after root canal filling procedures with GuttaCore (GC), cold lateral compaction (CLC) and warm vertical compaction (WVC) techniques in mandibular molars using micro-computed tomographic analysis. Thirty mesial roots of mandibular molars, with a type II Vertucci's canal configuration, were prepared to working length with a Reciproc R40 instrument and randomly assigned to one of the three experimental groups (n = 10), according to the technique used for root filling: GC, CLC or WVC. The GC group was filled with a size 40 GC obturator, whilst CLC and WVC groups used conventional gutta-percha cones. AH Plus sealer was used in all groups. The specimens were scanned at an isotropic resolution of 14.25 μm before and after root canal preparation and after root filling. Then, all pre- and postoperative cross-sectional images of the roots (n = 41 660) were screened to identify the presence of dentinal defects. Overall, 30.75% (n = 12 810) of the pre- + post-filling images displayed dentinal defects. In the GC, CLC and WVC groups, dentinal micro-cracks were observed in 18.68% (n = 2510), 15.99% (n = 2389) and 11.34% (n = 1506) of the cross-sectional images, respectively. All micro-cracks identified in the post-filling scans were also observed in the corresponding post-preparation images. Root fillings in all techniques did not induce the development of new dentinal micro-cracks. © 2016 International Endodontic Journal. Published by John Wiley & Sons Ltd.

    The aim of this study was to compare a computerized, laser-scanning Cavity Preparation Skill Evaluation System (CPSES) with conventional teachers' eye-hand grading assessment of dental students' Class I cavity preparation evaluations. Thirty-eight cavity preparations of lower left first molars made by junior dental students at a dental school in China were tested from September 2013 to November 2014. The outline and retention form, smoothness, depth, wall angulation, and cavity margin index of the preparations were evaluated by CPSES and then by teachers' eye-hand grading. The mean difference in scores for each method was considered, as was the variability of scores within each method. Compared with the teachers' eye-hand grading method, CPSES provided objective evaluation results that had statistically significant differences (pcavity preparation skills and encourage students in their self-paced learning and independent practice.

    We succeeded in obtaining the depth profile of (236)U for a sampling station in the Northeast Pacific Ocean using only one litre of seawater sample from each depth. For this purpose, a new procedure was developed that allowed for the preparation of accelerator mass spectrometry targets for trace uranium using only 100 μg of iron carrier material. The (236)U concentrations in water samples from the Northeast Pacific Ocean showed large variations from (9.26 ± 0.42) × 10(6) atoms/kg at 60 m depth to (0.08 ± 0.02) × 10(6) atoms/kg at a depth of 3000 m. The high (236)U concentrations in surface water reflect the input of (236)U by global and local fallout from nuclear weapons tests. The low (236)U concentrations in seawater from 1500 m and below are an indicator for the low vertical diffusion of surface water to deeper layers in the North Pacific Ocean. The total inventory of (236)U on the water column was (8.35 ± 0.23) × 10(12) atoms/m(2), which is lower compared to those of other ocean regions solely affected by global fallout on comparable latitudes. This study represents the first dataset for (236)U in the Pacific Ocean and shows the possibility of downsizing sample volumes which may help in future applications of (236)U as tracer for large ocean areas.

    The Waste Isolation Pilot Plant (WIPP) is an experimental facility located in southeastern New Mexico. It has been designed to determine the feasibility of the geologic disposal of defense-generated transuranic waste in a deep bedded-salt formation. The WIPP was also designed for disposal and will operate in that capacity if approved. The WIPP Performance Assessment Department at Sandia National Laboratories has been conducting analyses to assess the long-term performance of the WIPP. These analyses sometimes require the use of expert judgment. This Department has convened several expert-judgment panels and from that experience has developed an internal quality-assurance procedure to guide the formal elicitation of expert judgment. This protocol is based on the principles found in the decision-analysis literature.

    High-temperature crack growth under cyclic, static, and combined loading is received with an emphasis on fracture mechanics aspects. Experimental studies of the effects of loading history, microstructure, temperature, and environment on crack growth behavior are described and interpreted. The experimental evidence is used to examine crack growth parameters and theoretical models for fatigue, creep, and creep-fatigue crack propagation at elevated temperatures. The limitations of both elastic and elastic-plastic fracture mechanics for high-temperature subcritical crack growth are assessed. Existing techniques for modeling critical crack growth/ligament instability failure are also presented. Related topics of defect modeling and engineering flaw assessment procedures, nondestructive evaluation methods, and probabilistic failure analysis are briefly discussed. 142 refs., 33 figs.

    The current methods to assess the environmental impacts of plant pests differ in their approaches and there is a lack of the standardized procedures necessary to provide accurate and consistent results, demonstrating the complexity of developing a commonly accepted scheme for this purpose....... By including both the structural and functional components of the environment threatened by invasive alien species (IAS), in particular plant pests, we propose an environmental risk assessment scheme that addresses this complexity. Structural components are investigated by evaluating the impacts of the plant...... pest on genetic, species and landscape diversity. Functional components are evaluated by estimating how plant pests modify ecosystem services in order to determine the extent to which an IAS changes the functional traits that influence ecosystem services.

  6. A Multimode Adaptive Pushover Procedure for Seismic Assessment of Integral Bridges

    2013-01-01

    Full Text Available This paper presents a new adaptive pushover procedure to account for the effect of higher modes in order to accurately estimate the seismic response of bridges. The effect of higher modes is considered by introducing a minimum value for the total effective modal mass. The proposed method employs enough number of modes to ensure that the defined total effective modal mass participates in all increments of the pushover loading. An adaptive demand curve is also developed for assessment of the seismic demand. The efficiency and robustness of the proposed method are demonstrated by conducting a parametric study. The analysis includes 18 four-span integral bridges with various heights of piers. The inelastic response history analysis is employed as reference solution in this study. Numerical results indicate excellent accuracy of the proposed method in assessment of the seismic response. For most bridges investigated in this study, the difference between the estimated response of the proposed method and the inelastic response history analysis is less than 25% for displacements and 10% for internal forces. This indicates a very good accuracy compared to available pushover procedures in the literature. The proposed method is therefore recommended to be applied to the seismic performance evaluation of integral bridges for engineering applications.

    The number of environmental licence applications for projects affecting Indigenous peoples in Brazil has increased since the implementation of a major infrastructure program (Programa de Aceleração do Crescimento) in 2007. This increase has caused problems for Brazilian agencies involved in environmental licensing procedures (IBAMA, FUNAI and others). We analyze the Brazilian environmental licensing procedure for situations involving Indigenous peoples, Maroons (Quilombolas) or other traditional communities in order to identify potential improvements for Brazil and potentially other countries. Although Brazilian procedures are consistent with international best practice in environmental licensing, in practice social impacts are inadequately addressed, mitigation measures are poorly implemented, and there is a lack of enforcement and compliance. The paper is based on document analysis and interviews with key actors in governmental and non-governmental organizations and Indigenous leaders. We suggest that Free, Prior and Informed Consent (FPIC) processes need to be conducted at the earliest stages of project planning, and that Indigenous peoples should actively participate in impact assessment, monitoring and evaluation processes. In order to achieve a social licence to operate, there needs to be full recognition of traditional knowledge and acceptance of Indigenous values and concepts. We also recommend increased involvement of social experts and mediators as well as improved accountability, enforcement and grievance mechanisms in the licensing process. - Highlights: • The Brazilian environmental licensing system needs to address social impacts better. • Communities need to be consulted at the earliest stage possible. • Indigenous peoples need to be invited to participate in impact assessment teams. • Independent Indigenous committees to monitor implementation of mitigation measures. • Accountability, enforcement and grievance mechanisms need to be

  8. GIS-based procedure for site-specific risk assessment of pesticides for aquatic ecosystems.

    2008-01-01

    The EU Water Framework Directive states that the management of surface water must be based on a site-specific assessment of water quality, that is dependent on land use. As a result, to develop a robust chemical management policy for aquatic ecosystems, the ecotoxicological risk must be strictly related to the local conditions and characteristics of the system. This paper presents a methodology developed to assess the ecotoxicological risk of pesticides to site-specific aquatic ecosystems. Spatial and relational databases, provisional models and risk indices were integrated into Geographical Information Systems (GIS) to produce maps of exposure, effect and risk at watershed scale. Each active ingredient is characterised by a data set that includes input data as well as results represented by a risk assessment cartography. The aim of this procedure is to perform a site-specific risk assessment by integrating geographical distribution of predicted environmental concentrations (PECs), ecotoxicological effects and the potential/actual quality of the exposed ecosystem. Examples of pesticide risk maps for surface waters in Lombardia Region (Northern Italy) are shown.

    Cell viability in probiotic preparations is traditionally assessed by the plate count technique. Additionally, fluorescent staining combined with epifluorescence microscopy or flow cytometry has been developed for the viability assessment, but the currently available assays are either laborious or require highly sophisticated equipment. The aim of this study was to investigate the applicability of a microplate scale fluorochrome assay for predicting the cell state of freeze-dried Lactobacillus rhamnosus and Bifidobacterium animalis subsp. lactis preparations. In addition to viability assessment with LIVE/DEAD BacLight Bacterial Viability Kit, DiBAC(4)3 stain was used for the kinetic measurement of changes in bifidobacterial cell membrane functions during exposure to low pH. The microplate scale fluorochrome assay results on the viability and cell numbers of probiotic preparations correlated well with the results obtained with the culture-based technique and (with few exceptions) with epifluorescence microscopy. The assay was applicable also for the viability assessment of stressed (acid-treated) cells provided that the cell density in treatments was adjusted to the optimal measurement level of the fluorometer. The microplate scale fluorochrome assay offers a rapid and robust tool for the viability assessment of probiotic preparations, and enables also kinetic measurements.

    The purpose of this study was to prospectively compare participant experience and preference of limited preparation computed tomography colonography (CTC) with full-preparation colonoscopy in a consecutive series of patients at increased risk of colorectal cancer. CTC preparation comprised 180 ml diatrizoate meglumine, 80 ml barium and 30 mg bisacodyl. For the colonoscopy preparation 4 l of polyethylene glycol solution was used. Participants' experience and preference were compared using the Wilcoxon signed rank test and the chi-squared test, respectively. Associations between preference and experience parameters for the 173 participants were determined by logistic regression. Diarrhoea occurred in 94% of participants during CTC preparation. This side effect was perceived as severely or extremely burdensome by 29%. Nonetheless, the total burden was significantly lower for the CTC preparation than for colonoscopy (9% rated the CTC preparation as severely or extremely burdensome compared with 59% for colonoscopy; p<0.001). Participants experienced significantly more pain, discomfort and total burden with the colonoscopy procedure than with CTC (p<0.001). After 5 weeks, 69% preferred CTC, 8% were indifferent and 23% preferred colonoscopy (p<0.001). A burdensome colonoscopy preparation and pain at colonoscopy were associated with CTC preference (p<0.04). In conclusion, participants' experience and preference were rated in favour of CTC with limited bowel preparation compared with full-preparation colonoscopy. (orig.)

    Surgeons tend to view the robotic right colectomy (RRC) as an ideal beginning procedure to gain proficiency in robotic general and colorectal surgery. Nevertheless, oncological RRC, especially if performed with intracorporeal ileocolic anastomosis confectioning, cannot be considered a technically easier procedure. The aim of this study was to assess the learning curve of the RRC performed for oncological purposes and to evaluate its safety and efficacy investigating the perioperative and pathology outcomes in the different learning phases. Data on a consecutive series of 108 patients undergoing RRC with intracorporeal anastomosis between June 2011 and September 2015 at our institution were prospectively collected to evaluate surgical and short-term oncological outcomes. CUSUM (Cumulative Sum) and Risk-Adjusted (RA) CUSUM analysis were performed in order to perform a multidimensional assessment of the learning curve for the RRC surgical procedure. Intraoperative, postoperative and pathological outcomes were compared among the learning curve phases. Based on the CUSUM and RA-CUSUM analyses, the learning curve for RRC could be divided into 3 different phases: phase 1, the initial learning period (1st-44th case); phase 2, the consolidation period (45th-90th case); and phase 3, the mastery period (91th-108th case). Operation time, conversion to open surgery rate and the number of harvested lymph nodes significantly improve through the three learning phases. The learning curve for oncological RRC with intracorporeal anastomosis is composed of 3 phases. Our data indicate that the performance of RRC is safe from an oncological point of view in all of the three phases of the learning curve. However, the technical skills necessary to significantly reduce operative time, conversion to open surgery rate and to significantly improve the number of harvested lymph nodes were achieved after 44 procedures. These data suggest that it might be prudent to start the RRC learning curve

  15. Evaluating the Strange Situation Procedure (SSP to assess the bond between dogs and humans.

    Directory of Open Access Journals (Sweden)

    Therese Rehn

    Full Text Available The Strange Situation Procedure (SSP is increasingly being used to study attachment between dogs and humans. It has been developed from the Ainsworth Strange Situation Procedure, which is used extensively to investigate attachment between children and their parents. In this experiment, 12 female beagle dogs were tested in two treatments to identify possible order effects in the test, a potential weakness in the SSP. In one treatment (FS, dogs participated together with a 'familiar person' and a 'stranger'. In a control treatment (SS, the same dogs participated together with two unfamiliar people, 'stranger A' and 'stranger B'. Comparisons were made between episodes within as well as between treatments. As predicted in FS, dogs explored more in the presence of the familiar person than the stranger. Importantly, they also explored more in the presence of stranger A (who appeared in the same order as the familiar person and followed the same procedure than stranger B in SS. Furthermore, comparisons between treatments, where a familiar person was present in FS and stranger A was present in SS, showed no differences in exploration. In combination, these results indicate that the effect of a familiar person on dogs' exploratory behaviour, a key feature when assessing secure attachment styles, could not be tested reliably due to the order in which the familiar person and the stranger appear. It is proposed that in the future only counterbalanced versions of the SSP are used. Alternatively, since dogs reliably initiated more contact with the familiar person compared to the strangers, it is suggested that future studies on attachment in dogs towards humans should focus either on the behaviour of the dog in those episodes of the SSP when the person returns, or on reunion behaviour in other studies, specially designed to address dog-human interactions at this time.

    2008-11-15

    An assessment of off-site exposure from spills/releases of toxic chemicals can be conducted by compiling site-specific operational, geographic, demographic, and meteorological data and by using screening-level public-domain modeling tools (e.g., RMP Comp, ALOHA and DEGADIS). In general, the analysis is confined to the following: event-based simulations (allow for the use of known, constant, atmospheric conditions), known receptor distances (on the order of miles or less), short time scale for the distances considered (order of 10's of minutes or less), gently sloping rough terrain, dense and neutrally buoyant gas dispersion, known chemical inventory and infrastructure (used to define source-term), and known toxic endpoint (defines significance). While screening-level models are relatively simple to use, care must be taken to ensure that the results are meaningful. This approach allows one to assess risk from catastrophic release (e.g., via terrorism), or plausible release scenarios (related to standard operating procedures and industry standards). In addition, given receptor distance and toxic endpoint, the model can be used to predict the critical spill volume to realize significant off-site risk. This information can then be used to assess site storage and operation parameters and to determine the most economical and effective risk reduction measures to be applied.

    Background Observational measures of parent and child behaviours have a long history in child psychiatric and psychological intervention research, including the field of autism and developmental disability. We describe the development of the Standardised Observational Analogue Procedure (SOAP) for the assessment of parent–child behaviour before and after a structured parent training program for children with pervasive developmental disorders (PDD). We report on the use of this procedure in a pilot study of 12 participants with PDD. Results Inter-rater reliability across behaviours coded ranged from 75 to 100% agreement. Blindly scored observations of behaviour showed medium effect sizes for changes in inappropriate child behaviour. Analyses of baseline scores revealed a moderate positive correlation between inappropriate child behaviours as measured in all four SOAP conditions and parent ratings of child noncompliance (rs = .66, p .05). Conclusions As our treatment targeted compliance, these preliminary results suggest that the SOAP provides a valid measure of noncompliant behaviour in children with PDD and is sensitive to treatment effects on inappropriate child behaviours.

    The Army Study to Assess Risk and Resilience in Servicemembers (Army STARRS) is a multi-component epidemiological and neurobiological study of unprecedented size and complexity designed to generate actionable evidence-based recommendations to reduce US Army suicides and increase basic knowledge about determinants of suicidality by carrying out coordinated component studies. A number of major logistical challenges were faced in implementing these studies. The current report presents an overview of the approaches taken to meet these challenges, with a special focus on the field procedures used to implement the component studies. As detailed in the paper, these challenges were addressed at the onset of the initiative by establishing an Executive Committee, a Data Coordination Center (the Survey Research Center [SRC] at the University of Michigan), and study-specific design and analysis teams that worked with staff on instrumentation and field procedures. SRC staff, in turn, worked with the Office of the Deputy Under Secretary of the Army (ODUSA) and local Army Points of Contact (POCs) to address logistical issues and facilitate data collection. These structures, coupled with careful fieldworker training, supervision, and piloting, contributed to the major Army STARRS data collection efforts having higher response rates than previous large-scale studies of comparable military samples.

  5. Assessment procedure for the soft skills requested by Industry 4.0

    Cotet Gabriela Beatrice

    2017-01-01

    Full Text Available In the context of an increasingly more performant global and informational environment, as the one found in the virtual organization, the process of selecting and evaluating the human resources holds a particular important role. The premise behind this article is that of the need to adapt the human resource performance to the requests of the industry 4.0 being supported by the organizational culture. Following the analysis of the state of the art literature we concluded that there is no clear procedure for the assessment of the constellation of skills and personal qualities – soft skills requested by industry 4.0. These capabilities should complete professional technical hard-skills; the procedure should provide a map for the constellation of capabilities necessary to adapt and perform, in specific industry 4.0 activities. Current psychological evaluation systems consider only some of such requested capabilities not always the most relevant. To solve this problem, we tried to identify and evaluate what we considered as the core of the complex various skills required. Our research was centred on the use of a psychological instrument for evaluating transversal capabilities. The capabilities map needed for the evaluation and selection of the human resource fit to work in the industry 4.0 environment was designed after the application of this complex system of evaluation on successive series of students from the University POLITEHNICA of Bucharest.

    2003-07-01

    This report provides guidance on conducting a Level I PSA for internal events in NPPs, which is based on the method and procedure that was used in the PSA for the design of Korea Standard Nuclear Plants (KSNPs). Level I PSA is to delineate the accident sequences leading to core damage and to estimate their frequencies. It has been directly used for assessing and modifying the system safety and reliability as a key and base part of PSA. Also, Level I PSA provides insights into design weakness and into ways of preventing core damage, which in most cases is the precursor to accidents leading to major accidents. So Level I PSA has been used as the essential technical bases for risk-informed application in NPPs. The report consists six major procedural steps for Level I PSA; familiarization of plant, initiating event analysis, event tree analysis, system fault tree analysis, reliability data analysis, and accident sequence quantification. The report is intended to assist technical persons performing Level I PSA for NPPs. A particular aim is to promote a standardized framework, terminology and form of documentation for PSAs. On the other hand, this report would be useful for the managers or regulatory persons related to risk-informed regulation, and also for conducting PSA for other industries.

  7. Measuring implicit attitudes: A positive framing bias flaw in the Implicit Relational Assessment Procedure (IRAP).

    O'Shea, Brian; Watson, Derrick G; Brown, Gordon D A

    2016-02-01

    How can implicit attitudes best be measured? The Implicit Relational Assessment Procedure (IRAP), unlike the Implicit Association Test (IAT), claims to measure absolute, not just relative, implicit attitudes. In the IRAP, participants make congruent (Fat Person-Active: false; Fat Person-Unhealthy: true) or incongruent (Fat Person-Active: true; Fat Person-Unhealthy: false) responses in different blocks of trials. IRAP experiments have reported positive or neutral implicit attitudes (e.g., neutral attitudes toward fat people) in cases in which negative attitudes are normally found on explicit or other implicit measures. It was hypothesized that these results might reflect a positive framing bias (PFB) that occurs when participants complete the IRAP. Implicit attitudes toward categories with varying prior associations (nonwords, social systems, flowers and insects, thin and fat people) were measured. Three conditions (standard, positive framing, and negative framing) were used to measure whether framing influenced estimates of implicit attitudes. It was found that IRAP scores were influenced by how the task was framed to the participants, that the framing effect was modulated by the strength of prior stimulus associations, and that a default PFB led to an overestimation of positive implicit attitudes when measured by the IRAP. Overall, the findings question the validity of the IRAP as a tool for the measurement of absolute implicit attitudes. A new tool (Simple Implicit Procedure:SIP) for measuring absolute, not just relative, implicit attitudes is proposed. (PsycINFO Database Record

    It is necessary to assess radiation dose to workers due to inhalation of airborne particulates containing naturally occurring radioactive materials (NORM) to ensure radiological safety required by the Natural Radiation Safety Management Act. The objective of this study is to develop an internal dose assessment procedure for workers at industries using raw materials containing natural radionuclides. The dose assessment procedure was developed based on harmonization, accuracy, and proportionality. The procedure includes determination of dose assessment necessity, preliminary dose estimation, airborne particulate sampling and characterization, and detailed assessment of radiation dose. The developed dose assessment procedure is as follows. Radioactivity concentration criteria to determine dose assessment necessity are 10 Bq·g-1 for 40K and 1 Bq·g-1 for the other natural radionuclides. The preliminary dose estimation is performed using annual limit on intake (ALI). The estimated doses are classified into 3 groups (<0.1 mSv, 0.1-0.3 mSv, and >0.3 mSv). Air sampling methods are determined based on the dose estimates. Detailed dose assessment is performed using air sampling and particulate characterization. The final dose results are classified into 4 different levels (<0.1 mSv, 0.1-0.3 mSv, 0.3-1 mSv, and >1 mSv). Proper radiation protection measures are suggested according to the dose level. The developed dose assessment procedure was applied for NORM industries in Korea, including coal combustion, phosphate processing, and monazite handing facilities. The developed procedure provides consistent dose assessment results and contributes to the establishment of optimization of radiological protection in NORM industries.

    Flat titanium dioxide films, to be used as the acceptor layer in bilayer hybrid solar cell devices, were prepared by spray-pyrolysis and by spin-casting. Both preparation methods resulted in anatase titania films with similar optical and electronic properties but considerably different film morphologies. Spray pyrolysis resulted in dense TiO₂ films grown onto and affected by the surface roughness of the underlying conducting glass substrates. The spin-casting preparation procedure resulted in nanoporous titania films. Hybrid solar cell devices with varying layer thickness of the small-molecule semiconducting dye TDCV-TPA were investigated. Devices built with spray-pyrolyzed titania substrates yielded conversion efficiencies up to 0.47%. Spin-cast titania substrates exhibited short circuits for thin dye layer thickness. For thicker dye layers the performance of these devices was up to 0.6% due to the higher interfacial area for charge separation of these nanoporous TiO₂ substrates.

    In the present study, we tested a computer-based procedure for assessing very concise summaries (50 words long) of two types of text (narrative and expository) using latent semantic analysis (LSA) in comparison with the judgments of four human experts. LSA was used to estimate semantic similarity using six different methods: four holistic (summary-text, summary-summaries, summary-expert summaries, and pregraded-ungraded summary) and two componential (summary-sentence text and summary-main sentence text). A total of 390 Spanish middle and high school students (14-16 years old) and six experts read a narrative or expository text and later summarized it. The results support the viability of developing a computerized assessment tool using human judgments and LSA, although the correlation between human judgments and LSA was higher in the narrative text than in the expository, and LSA correlated more with human content ratings thanwith hu mancoherence ratings. Finally, theholistic methods were found to be more reliable than the componential methods analyzed in this study.

  12. Procedures to relate the NII safety assessment principles for nuclear reactors to risk

    1985-01-01

    Within the framework of the Public Inquiry into the proposed pressurised water reactor (PWR) at Sizewell, estimates were made of the levels of individual and societal risk from a PWR designed in a manner which would conform to the safety assessment principles formulated by the Nuclear Installations Inspectorate (NII). The procedures used to derive these levels of risk are described in this report. The opportunity has also been taken to revise the risk estimates made at the time of the Inquiry by taking account of additional data which were not then available, and to provide further quantification of the likely range of uncertainty in the predictions. This re-analysis has led to small changes in the levels of risk previously evaluated, but these are not sufficient to affect the broad conclusions reached before. For a reactor just conforming to the NII safety assessment principles a maximum individual risk of fatal cancer of about 10 sup - sup 6 per year of reactor operation has been estimated; the societal ris...

  13. Environmental Impacts of Surgical Procedures: Life Cycle Assessment of Hysterectomy in the United States

    The healthcare sector is a driver of economic growth in the U.S., with spending on healthcare in 2012 reaching $2.8 trillion, or 17% of the U.S. gross domestic product, but it is also a significant source of emissions that adversely impact environmental and public health. The current state of the healthcare industry offers significant opportunities for environmental efficiency improvements, potentially leading to reductions in costs, resource use, and waste without compromising patient care. However, limited research exists that can provide quantitative, sustainable solutions. The operating room is the most resource-intensive area of a hospital, and surgery is therefore an important focal point to understand healthcare-related emissions. Hybrid life cycle assessment (LCA) was used to quantify environmental emissions from four different surgical approaches (abdominal, vaginal, laparoscopic, and robotic) used in the second most common major procedure for women in the U.S., the hysterectomy. Data were collected from 62 cases of hysterectomy. Life cycle assessment results show that major sources of environmental emissions include the production of disposable materials and single-use surgical devices, energy used for heating, ventilation, and air conditioning, and anesthetic gases. By scientifically evaluating emissions, the healthcare industry can strategically optimize its transition to a more sustainable system. PMID:25517602

    In this paper, the total technical roadmap and the procedure to assess the aircraft impact risk will be introduced. In the first year of the research project, 2012, we developed aircraft impact accident scenario and performed preliminary fragility analysis of the local failure of the targeted wall by aircraft impact. An aircraft impact event can be characterized by the appropriate load parameters (i. e., aircraft type, mass, velocity, angle of crash, etc.). Therefore, the reference parameter should be selected to represent each load effect in order to evaluate the capacity/fragility of SSCs using deterministic or probabilistic methods. This is similar to the use of the peak ground acceleration (PGA) to represent the ground motion spectrum of the earthquake in the seismic probabilistic risk assessment (SPRA) approach. We developed the methodology to decide on the reference parameter for the aircraft impact risk quantification among some reasonable candidates, which can represent many uncertain loading parameters. To detect the response and the damage of the target structure, missile-target interaction method and Riera's time-history analysis method have been used primarily in the aircraft impact research area. To define the reference loading parameter, we need to perform repetitive simulations for many analysis cases. Thus, we applied a revised version of Riera's method, which is appropriate for a simplified impact simulation. The target NPP to determine the reference parameter and evaluate the preliminary assessment of aircraft impact risk was selected among the typical Korean PWR NPPs. The response has been calculated for pre-stressed concrete containment buildings subjected to aircraft impact loading, and the responses according to each reference parameter have been analyzed. Recently, we also evaluated the floor response spectra for the locations of important components for the estimation of the failure probabilities and fragility functions of

    The difficulty to deal with human factors in non-destructive testing (NDT) stems from their diversity and complexity - no single human or organizational factor is responsible for the entire fluctuations in the NDT performance. The typical approach to decrease the variability in the inspection results had been found in replacing manual NDT with mechanized methods. However, even though some human errors can be avoided by automating the process, there are new risks that can arise from its application and need to be further investigated. To address this problem, a combination of theoretical and practical approaches should be applied, where the source of error is not seen only in the inspector, but also in his interaction with social and technical systems, as well as the organization. An analysis of potential risks in the use of mechanized inspections methods for spent fuel canisters has shown potential for human error in acquisition, as well as in the evaluation of the gathered results. Assessed causes of those errors lay in the inspector, but also in the organization and in shortcomings of the inspection procedure. The aim of the analysis was to provide with preventive measures and optimization recommendations. Those include further automation of the process, application of human redundancy, improvements of the inspection procedure, hardware and software improvements etc. Before improvements can be made, there is a need to understand the resulting processes and the influence of their interaction on the inspection results. The results have shown that when working with an automated system, one must avoid over relying on its proper functioning and form appropriate trust towards automation. Furthermore, human redundancy should be applied only in cases where the redundant inspectors are completely unaware of each other, in order to avoid the effects of social loafing and shirking. The inspection procedure is one of the most important tools in the application of NDT. On an

    Full Text Available Small intestine plays an important role in the first-pass metabolism of orally ingested xenobiotics as a result of expression of both Phase I and Phase II metabolic enzymes, together with associated transporters. Intestinal microsomes thus can be used to study susceptibility of compounds to metabolism in vitro. The present study was undertaken to have a comparative assessment between different methods of preparation of rodent intestinal microsomes. Mouse and rat intestinal microsomes were prepared by two methods, in method A intestines were homogenized, while in method B mucosal cells were scrapped followed by homogenization. Further, microsomes were prepared by centrifugation (10000xg followed by ultra centrifugation (100000xg of the homogenates. The prepared microsomes were characterized for protein concentration using Bradford′s method and CYP450 content using carbon monoxide bubbling method. The protein concentration and CYP450 content in microsomes prepared by method B was significantly higher than method A. In conclusion, superior quality intestinal microsomes can be obtained from rodents by using scrapped intestinal mucosal cells as compared to the intestinal homogenates.

    The aim of this pilot study was to evaluate the feasibility of a new tooth preparation assessment software, Preppr, as an educational tool for dental students in achieving optimal parameters for a crown preparation. In February 2015, 30 dental students in their fourth year in a five-year undergraduate dental curriculum in New Zealand were randomly selected from a pool of volunteers (N=40) out of the total class of 85. The participants were placed into one of three groups of ten students each: Group A, the control group, received only written and pictorial instructions; Group B received tutor evaluation and feedback; and Group C performed self-directed learning with the aid of Preppr. Each student was asked to prepare an all-ceramic crown on the lower first molar typodont within three hours and to repeat the exercise three times over the next four weeks. The exercise stipulated a 1 mm finish line dimension and total convergence angles (TOC) between 10 and 20 degrees. Fulfillment of these parameters was taken as an acceptable preparation. The results showed that Group C had the highest percentage of students who achieved minimum finish line dimensions and acceptable TOC angles. Those students also achieved the stipulated requirements earlier than the other groups. This study's findings provide promising data on the feasibility of using Preppr as a self-directed educational tool for students training to prepare dental crowns.

    The Commission on Dental Accreditation (CODA)'s accreditation standards for dental schools state that "graduates must demonstrate the ability to self-assess." Therefore, dental schools have developed preclinical and clinical self-assessment (SA) protocols aimed at fostering a reflective process. This study comparing students' visual SA with students' digital SA and with faculty assessment was designed to test the hypothesis that higher agreement would occur when utilizing a digital evaluation. Twenty-five first-year dental students at one dental school participated by preparing a mesial occlusal preparation on tooth #30 and performing both types of SAs. A faculty evaluation was then performed both visually and digitally using the same evaluation criteria. The Kappa statistic was used to measure agreement between evaluators. The results showed statistically significant moderate agreement between the faculty visual and faculty digital modes of evaluation for occlusal shape (K=0.507, p=0.002), proximal shape (K=0.564, p=0.001), orientation (K=0.425, p=0.001), and definition (K=0.480, p=0.001). There was slight to poor agreement between the student visual and faculty visual assessment, except for preparation orientation occlusal shape (K=0.164, p=0.022), proximal shape (K=-0.227, p=0.032), orientation (K=0.253, p=0.041), and definition (K=-0.027, p=0.824). This study showed that the students had challenges in self-assessing even when using CAD/CAM and the digital assessment did not improve the amount of student/faculty agreement.

    Animal management often involves procedures that, while unlikely to cause physical pain, still cause aversive responses. The domestic horse (Equus caballus) regularly has excessive hair clipped off to facilitate its use as a riding/driving animal and this procedure causes adverse behavioral responses in some animals. The aim of this study was to compare behavioral and physiological measures to assess the aversive effect of this procedure. Ten horses were selected on the basis of being either compliant (C: n=5) or non-compliant (NC: n=5) during this procedure. The horses were subjected to a sham clipping procedure (SC: where the blades had been removed from the clippers) for a period of ten minutes. Measures were taken pre, during and post SC (-10min to +30min) and mean values calculated for ALL horses and for C and NC separately. Behavioral activity was scored (scale 1-5) by twenty students from video footage in (phase/group-blind scoring). Heart rate (HR), salivary cortisol and eye temperature were monitored throughout the procedure. The NC horses were found to be significantly more behaviorally active/less relaxed throughout the trial than C horses (pphysiological responses indicated that ALL horses found the procedure aversive. Eye temperature could be used as an objective and immediate measure of how an animal is responding to a specific situation in order to evaluate management procedures and adapt them where appropriate to reduce the negative impact on animal health and welfare.

  2. Stepwise optimization of the procedure for assessment of circulating progenitor cells in patients with myocardial infarction.

    Directory of Open Access Journals (Sweden)

    Yu-Xin Cui

    Full Text Available BACKGROUND: The number and functional activity of circulating progenitor cells (CPCs is altered in diabetic patients. Furthermore, reduced CPC count has been shown to independently predict cardiovascular events. Validation of CPCs as a biomarker for cardiovascular risk stratification requires rigorous methodology. Before a standard operation protocol (SOP can be designed for such a trial, a variety of technical issues have to be addressed fundamentally, which include the appropriate type of red blood cell lysis buffer, FMO or isotype controls to identify rare cell populations from background noise, optimal antibody dilutions and conditions of sample storage. We herein propose improvements in critical steps of CPC isolation, antigenic characterization and determination of functional competence for final application in a prospective investigation of CPCs as a biomarker of outcome following acute myocardial infarction. METHODS AND FINDINGS: In this validation study, we refined the standard operating procedure (SOP for flow cytometry characterisation and functional analysis of CPCs from the first 18 patients of the Progenitor Cell Response after Myocardial Infarction Study (ProMIS. ProMIS aims to verify the prognostic value of CPCs in patients with either ST elevation or non-ST elevation myocardial infarction with or without diabetes mellitus, using cardiac magnetic resonance imaging (MRI for assessment of ventricular function as a primary endpoint. Results indicate crucial steps for SOP implementation, namely timely cell isolation after sampling, use of appropriate lysis buffer to separate blood cell types and minimize the acquisition events during flow cytometry, adoption of proper fluorophore combination and antibody titration for multiple antigenic detection and introduction of counting beads for precise quantification of functional CPC activity in migration assay.

    Full Text Available In this paper, a simplified procedure for the assessment of pavement structural integrity and the level of service for urban road surfaces is presented. A sample of 109 Asphalt Concrete (AC urban pavements of an Italian road network was considered to validate the methodology. As part of this research, the most recurrent defects, those never encountered and those not defined with respect to the list collected in the ASTM D6433 have been determined by statistical analysis. The goal of this research is the improvement of the ASTM D6433 Distress Identification Catalogue to be adapted to urban road surfaces. The presented methodology includes the implementation of a Visual Basic for Application (VBA language-based program for the computerization of Pavement Condition Index (PCI calculation with interpolation by the parametric cubic spline of all of the density/deduct value curves of ASTM D6433 distress types. Also, two new distress definitions (for manholes and for tree roots and new density/deduct curve values were proposed to achieve a new distress identification manual for urban road pavements. To validate the presented methodology, for the 109 urban pavements considered, the PCI was calculated using the new distress catalogue and using the ASTM D6433 implemented on PAVERTM. The results of the linear regression between them and their statistical parameters are presented in this paper. The comparison of the results shows that the proposed method is suitable for the identification and assessment of observed distress in urban pavement surfaces at the PCI-based scale.

    In many areas of Italy, urban flooding or floods in small mountain basins, induced by heavy precipitations on subdaily scale, represent remarkable hazards able to cause huge damages and casualties often increased by very high population density. A proper assessment about how frequency and magnitude of such events could change under the effect of Climate Changes (CC) is crucial for the development of future territorial planning (such as early warning systems). The current constraints of climate modeling, also using high resolution RCM, prevent an adequate representation of subdaily precipitation patterns (mainly concerning extreme values) while available observed datasets are often unsuitable for the application of the bias-correction (BC) techniques requiring long time series. In this work, a new procedure is proposed: at point scale, precipitation outputs on 24 and 48 hours are provided by high resolution (about 8km) climate simulation performed through the RCM COSMO_CLM driven by GCM CMCC_CM and bias-corrected by quantile mapping approach. These ones are adopted for a monthly stochastic disaggregation approach combining Random Parameter Bartlett-Lewis (RPBL) gamma model with appropriate rainfall disaggregation technique. The last one implements empirical correction procedures, called adjusting procedures, to modify the model rainfall output, so that it is consistent with the observed rainfall values on daily time scale. In order to take into account the great difficulties related to minimization of objective function required by retrieving the 7 RPBL parameters, for each dataset the computations are repeated twenty times. Moreover, adopting statistical properties on 24 and 48 hours to retrieve RPBL parameters allows, according Bo et al. (1994), to infer statistical properties until hourly scale maintaining the information content about the possible changes in precipitation patterns due to CC. The entire simulation chain is tested on Baiso weather station, in

    Objective self-assessment is essential to learning and continued competence in dentistry. A computer-assisted design/computer-assisted manufacturing (CAD/CAM) learning software (prepCheck, Sirona) allows students to objectively assess their performance in preclinical prosthodontics. The aim of this study was to evaluate students' perceptions of CAD/CAM learning software for preclinical prosthodontics exercises. In 2014, all third-year dental students at Harvard School of Dental Medicine (n=36) were individually instructed by a trained faculty member in using prepCheck. Each student completed a preclinical formative exercise (#18) and summative examination (#30) for ceramometal crown preparation and evaluated the preparation using five assessment tools (reduction, margin width, surface finish, taper, and undercut) in prepCheck. The students then rated each of the five tools for usefulness, user-friendliness, and frequency of use on a scale from 1=lowest to 5=highest. Faculty members graded the tooth preparations as pass (P), marginal-pass (MP), or fail (F). The survey response rate was 100%. The tools for undercut and taper had the highest scores for usefulness, user-friendliness, and frequency of use. The reduction tool score was significantly lower in all categories (psoftware as significantly more useful.

    1998-08-27

    A modified rapid plate assay procedure was developed, that allowed quantifiable measurement of nisin production by Lactococcus lactis growing directly on agar media. Using this direct plate assay, several nutritional parameters were assessed for their influence on nisin production (as distinct from their influence on growth) by L. lactis subsp. lactis ATCC 11454 growing on standard M17 based media over 3 and 6 h incubation periods. Glucose was found to be the optimal carbon source tested, with glycerol having the greatest suppressive effect. The addition of salts suppressed nisin production on a per cell basis, except MnCl2. This direct plate method proved to be a good pilot assay for rapidly and quantifiably investigating the initial effects of different parameters on nisin production by L. lactis, prior to conducting more intensive broth batch culture assays. The data obtained in this study indicate that certain nutritional parameters can impose a repressive effect on nisin production. Elucidation of how these parameters control the amount of nisin produced will provide further insight into the regulation of nisin biosynthesis in L. lactis.

    Floriana Petrone

    2014-07-01

    Full Text Available This work deals with the development of a mechanics-based shear model for reinforced concrete (RC elements strengthened in shear with fiber-reinforced polymer (FRP and a design/assessment procedure capable of predicting the failure sequence of resisting elements: the yielding of existing transverse steel ties and the debonding of FRP sheets/strips, while checking the corresponding compressive stress in concrete. The research aims at the definition of an accurate capacity equation, consistent with the requirement of the pseudo-ductile shear behavior of structural elements, that is, transverse steel ties yield before FRP debonding and concrete crushing. For the purpose of validating the proposed model, an extended parametric study and a comparison against experimental results have been conducted: it is proven that the common accepted rule of assuming the shear capacity of RC members strengthened in shear with FRP as the sum of the maximum contribution of both FRP and stirrups can lead to an unsafe overestimation of the shear capacity. This issue has been pointed out by some authors, when comparing experimental shear capacity values with the theoretical ones, but without giving a convincing explanation of that. In this sense, the proposed model represents also a valid instrument to better understand the mechanical behavior of FRP-RC beams in shear and to calculate their actual shear capacity.

    Full Text Available A number of assessment studies in recent years have shown that the educational achievement of learners in South African schools is unacceptably poor. The Department of Education’s systemic evaluations, conducted in Grade 3 (first cycle in 2001, second cycle in 2007 show very low levels of literacy among learners. Reading comprehension and writing scores averaged 39% for the first and 36% for the second cycle. Research indicates that less attention has been given to children’s reading comprehension skills compared to decoding skills. Teacher preparation programmes should provide candidates with a rigorous, research-based curriculum and opportunities to practise a range of predefined skills and knowledge. The demands of competent literacy instruction and assessment, and the training experiences necessary to learn it, have been seriously underestimated by universities. Teacher education programmes should ensure that teachers, amongst other crucial aspects, know how to assess the progress of every student and change instruction when it is not working and also know how to communicate results of assessments to various stakeholders, especially parents. The purpose of this article is to report on the training that pre-service teachers receive, related to reading comprehension assessment practices, within a BEd foundation phase teacher preparation programme.

    Echinacea purpurea, Echinacea angustifoli and Echinacea pallida are frequently used as medicinal plants. Besides asking for evidence on their efficacy, there is an increasing interest for safety data. This review systematically presents the available literature on drug interactions, contraindications, adverse events, duration of use, and safety of use in pregnant and nursing women, and assesses the safety profile of corresponding Echinacea preparations. It is noteworthy that all safety data reported are as product specific as the pharmacological or efficacy data are. In pharmacokinetic herb-drug interaction studies performed in vivo, no significant inhibitions of human CYP2D6 and CYP3A4 isoforms have been found after the administration of standardized E. purpurea preparations. However, contradictory results exist in studies using liver microsomes. Adverse events reported during clinical trials following administration of Echinacea spp. mono-preparations were generally mild and mostly without causality. Due to published long term studies with continuous ingestion of different Echinacea preparations up to 6 month with no reported toxicological concerns, Echinacea can be recommended also for long-term use. Moreover, the contraindications in cases of autoimmune diseases and immune-suppression are questionable, since lipophilic Echinacea preparations containing alkamides suppress cellular immune responses, and beneficial effects in autoimmunity were reported. The same applies for the use during pregnancy. Although there has been some impact reported on embryonic angiogenesis in mice, no association with an increased risk for major or minor malformations during organogenesis was found in a literature review. Altogether, the different evaluated Echinacea preparations are well-tolerated herbal medicines in the management in children and adults alike. Georg Thieme Verlag KG Stuttgart · New York.

    This study uses the theoretical framework of domain-specific problem solving to explore the procedures students use to solve multiple-choice problems about biology concepts. We designed several multiple-choice problems and administered them on four exams. We trained students to produce written descriptions of how they solved the problem, and this allowed us to systematically investigate their problem-solving procedures. We identified a range of procedures and organized them as domain general, domain specific, or hybrid. We also identified domain-general and domain-specific errors made by students during problem solving. We found that students use domain-general and hybrid procedures more frequently when solving lower-order problems than higher-order problems, while they use domain-specific procedures more frequently when solving higher-order problems. Additionally, the more domain-specific procedures students used, the higher the likelihood that they would answer the problem correctly, up to five procedures. However, if students used just one domain-general procedure, they were as likely to answer the problem correctly as if they had used two to five domain-general procedures. Our findings provide a categorization scheme and framework for additional research on biology problem solving and suggest several important implications for researchers and instructors.

    Tetrodotoxin (TTX) is one of the most potent marine neurotoxins reported. The global distribution of this toxin is spreading with the European Atlantic coastline now being affected. Climate change and increasing pollution have been suggested as underlying causes for this. In the present study, two different sample preparation techniques were used to extract TTX from Trumpet shells and pufferfish samples. Both extraction procedures (accelerated solvent extraction (ASE) and a simple solvent extraction) were shown to provide good recoveries (80-92%). A UPLC-MS/MS method was developed for the analysis of TTX and validated following the guidelines contained in the Commission Decision 2002/657/EC for chemical contaminant analysis. The performance of this procedure was demonstrated to be fit for purpose. This study is the first report on the use of ASE as a mean for TTX extraction, the use of UPLC-MS/MS for TTX analysis, and the validation of this method for TTX in gastropods.

    Full Text Available Soil DNA extraction has become a critical step in describing microbial biodiversity. Historically, ascertaining overarching microbial ecological theories has been hindered as independent studies have used numerous custom and commercial DNA extraction procedures. For that reason, a standardized soil DNA extraction method (ISO-11063 was previously published. However, although this ISO method is suited for molecular tools such as quantitative PCR and community fingerprinting techniques, it has only been optimized for examining soil bacteria. Therefore, the aim of this study was to assess an appropriate soil DNA extraction procedure for examining bacterial, archaeal and fungal diversity in soils of contrasting land-use and physico-chemical properties. Three different procedures were tested: the ISO-11063 standard; a custom procedure (GnS-GII; and a modified ISO procedure (ISOm which includes a different mechanical lysis step (a FastPrep ®-24 lysis step instead of the recommended bead-beating. The efficacy of each method was first assessed by estimating microbial biomass through total DNA quantification. Then, the abundances and community structure of bacteria, archaea and fungi were determined using real-time PCR and terminal restriction fragment length polymorphism approaches. Results showed that DNA yield was improved with the GnS-GII and ISOm procedures, and fungal community patterns were found to be strongly dependent on the extraction method. The main methodological factor responsible for differences between extraction procedure efficiencies was found to be the soil homogenization step. For integrative studies which aim to examine bacteria, archaea and fungi simultaneously, the ISOm procedure results in higher DNA recovery and better represents microbial communities.

  18. Integrated assessment procedure for determining the fracture strength of glass components in CSP systems

    Directory of Open Access Journals (Sweden)

    L. Guerra Rosa

    2014-10-01

    Full Text Available The structural integrity and reliability of glass components are key issues for concentrated solar power (CSP systems. For example, the glass windows in a solar furnace may suffer catastrophic fracture due to thermal and structural loadings, including reaction chamber pressure cycling. Predicting design strength provides the basis for which the optical components and mounting assembly can be designed so that failure does not occur over the operational lifetime of a given CSP system. The fracture strength of brittle materials is dependent on the size and distribution of cracks or surface flaws. Due to the inherent brittleness of glass resulting in catastrophic failure, conservative design approaches are currently used for the development of optical components made of glass, which generally neglect the specific glass composition as well as subcritical crack growth, surface area under stress, and nature of the load – either static or cyclic – phenomena. In this paper, several methods to characterize the strength of glass are discussed to aid engineers in predicting a design strength for a given surface finish, glass type, and environment. Based on the Weibull statistical approach and experimental data available on testing silica glass rod specimens, a theoretical model is developed for estimating their fracture strength under typical loading conditions. Then, an integrated assessment procedure for structural glass elements is further developed based on fracture mechanics and the theory of probability, which is based on the probabilistic modelling of the complex behaviour of glass fracture but avoids the complexity for calculation in applications. As an example, the design strength of a glass window suitable for a solar furnace reaction chamber is highlighted.

    Nanoparticle preparations of heavy metals have attracted enormous scientific and technological interest. Biologically produced nanoparticle preparations of heavy metals are elaborately described in traditional texts and being widely prescribed. The underlying interactions of nano preparations within the physiological fluids are key feature to understand their biological impact. In this perspective, we performed an experimental assessment of the toxicity potential of a marketed metallic preparation named Vasant Kusumakar Ras (VKR), wherein different heavy metals in composite form are reduced to nanoparticle size to produce the desired effect in diabetes and its complications. VKR (50mg/kg) was administered to Albino Wistar rats rendered diabetic using streptozotocin (90mg/kg) in 2 days old neonates. Anti-hyperglycemic effect was observed with VKR along with increased levels of plasma insulin. Renal variables including total proteins and albumin along with glomerular filtration rate were found to improve biochemically. The results were supplemented by effects on different inflammatory and growth factors like TNF-α, nitric oxide, TGF-β and VEGF. However, the results observed in kidney histopathology were not in accordance with the biochemical parameters. Inflammation observed in kidney was confirmed by immunostaining metallothionein, which was due to the accumulation of heavy metals. Furthermore, mercury accumulation in kidney further confirmed by autometallography, which activated mononuclear phagocyte system, which generated an immune response. This was further supported by increase in the extent of apoptosis in kidney tissues. In conclusion, nanoparticle preparations of heavy metals can be toxic to kidney if it is not regulated with respect to its surface chemistry and dosage.

    Neptunium (Np) and plutonium (Pu) are two key radionuclides for the long-term disposal of nuclear waste. Within this context Opalinus Clay formations are considered as a potential location for disposal of high-level radioactive waste. In the framework of experiments studying the diffusion behavior and retention of actinides under repository conditions, the present work focuses on the development of an analytical-chemical procedure for the determination of Np and Pu in clay (or clay-rich soil) samples. The procedure aims at the simultaneous determination of Np and Pu at femto- to attogram levels with AMS. Fields of application are the investigation of global fallout actinides in environmental clay-rich samples or the diffusion behavior of actinides in compacted clay liners used as technical barriers in nuclear waste repositories. Clay samples are spiked with certified standards of Pu-242 and Np-237. The analytical method, including a) leaching of the spiked clay samples, b) redox adjustments of Np and Pu, c) chromatographic separation of Np and Pu from the sample matrix and d) measurement of the actinides with Sector Field (SF)-ICP-MS will be presented. The suitability of a Pu isotope as non-isotopic tracer for determination of Np-237 is evaluated by determining the chemical yield using SF-ICP-MS.

  5. Reliability assessment of a manual-based procedure towards learning curve modeling and fmea analysis

    Full Text Available Separation procedures in drug Distribution Centers (DC are manual-based activities prone to failures such as shipping exchanged, expired or broken drugs to the customer. Two interventions seem as promising in improving the reliability in the separation procedure: (i selection and allocation of appropriate operators to the procedure, and (ii analysis of potential failure modes incurred by selected operators. This article integrates Learning Curves (LC and FMEA (Failure Mode and Effect Analysis aimed at reducing the occurrence of failures in the manual separation of a drug DC. LCs parameters enable generating an index to identify the recommended operators to perform the procedures. The FMEA is then applied to the separation procedure carried out by the selected operators in order to identify failure modes. It also deployed the traditional FMEA severity index into two sub-indexes related to financial issues and damage to company´s image in order to characterize failures severity. When applied to a drug DC, the proposed method significantly reduced the frequency and severity of failures in the separation procedure.

    @@ Ordered and disordered double perovskite Sr2FeMoO6 ceramics have been investigated by powder x-ray diffraction,magnetic and transport measurements, as well as Mossbauer spectroscopy. The heavily disordered sample can be acquired by annealing the ordered samples in argon. The annealing procedure affects not only the nature of grain boundaries but also the grain itself. The evidence of Mossbauer spectra performed at 77 and 300 K indicates that there exist small oxygen deficient clusters of SrFeO3-y in the disordered sample. The paramagnetic Fe4+ and Fe3+ ions in the compound subsist down to 77 K and the ratio of Fe4+/Fe3+ increases with decreasing temperature.

    A series of nanocrystalline γ-alumina are synthesized by different procedures, namely, thermal decomposition method (sample A), precipitation method (sample B) and sol-gel method using sucrose and hexadecyltrimethyl ammonium bromide (CTAB) as templates (samples C and D, respectively). Textural and acidic properties of T-alumina samples are characterized by XRD, N2 adsorption-desorption and NH3-TPD techniques. Vapor-phase dehydration of methanol into dimethyl ether is carried out over these samples. Among them, sample C shows the highest catalytic activity. NH3-TPD analysis reveals that the sample with smaller crystallite size possesses higher concentration of medium acidic sites and consequently higher catalytic activity. Thermal decomposition method leads to decrease in both surface area and moderate acidity, therefore it is the cause of lower catalytic activity.

    2011-04-01

    A novel sample preparation method for auxin analysis in plant samples was developed by vacuum microwave-assisted extraction (VMAE) followed by molecularly imprinted clean-up procedure. The method was based on two steps. In the first one, conventional solvent extraction was replaced by VMAE for extraction of auxins from plant tissues. This step provided efficient extraction of 3-indole acetic acid (IAA) from plant with dramatically decreased extraction time, furthermore prevented auxins from degradation by creating a reduced oxygen environment under vacuum condition. In the second step, the raw extract of VMAE was further subjected to a clean-up procedure by magnetic molecularly imprinted polymer (MIP) beads. Owing to the high molecular recognition ability of the magnetic MIP beads for IAA and 3-indole-butyric acid (IBA), the two target auxins in plants can be selectively enriched and the interfering substance can be eliminated by dealing with a magnetic separation procedure. Both the VMAE and the molecularly imprinted clean-up conditions were investigated. The proposed sample preparation method was coupled with high-performance liquid chromatogram and fluorescence detection for determination of IAA and IBA in peas and rice. The detection limits obtained for IAA and IBA were 0.47 and 1.6 ng/mL and the relative standard deviation were 2.3% and 2.1%, respectively. The IAA contents in pea seeds, pea embryo, pea roots and rice seeds were determined. The recoveries were ranged from 70.0% to 85.6%. The proposed method was also applied to investigate the developmental profiles of IAA concentration in pea seeds and rice seeds during seed germination.

    The study describes a new "one-pot" route to the synthesis of N-9-fluorenylmethyloxycarbonyl (Fmoc) α-amino diazoketones. The procedure was tested on a series of commercially available free or side-chain protected α-amino acids employed as precursors. The conversion into the title compounds was achieved by masking and activating the α-amino acids with a single reagent, namely, 9-fluorenylmethyl chloroformate (Fmoc-Cl). The resulting N-protected mixed anhydrides were reacted with diazomethane to lead to the α-amino diazoketones, which were isolated by flash column chromatography in very good to excellent overall yields. The versatility of the procedure was verified on lipophilic α-amino acids and further demonstrated by the preparation of N-Fmoc-α-amino diazoketones also from α-amino acids containing side-chain masking groups, which are orthogonal to the Fmoc one. The results confirmed that tert-butyloxycarbonyl (Boc), tert-butyl ((t)Bu), and 2,2,4,6,7-pentamethyldihydrobenzofuran-5-sulfonyl (Pbf), three acid-labile protecting groups mostly adopted in the solution and solid-phase peptide synthesis, are compatible to the adopted reaction conditions. In all cases, the formation of the corresponding C-methyl ester of the starting amino acid was not observed. Moreover, the proposed method respects the chirality of the starting α-amino acids. No racemization occurred when the procedure was applied to the synthesis of the respective N-Fmoc-protected α-amino diazoketones from L-isoleucine and L-threonine and to the preparation of a diastereomeric pair of N-Fmoc-protected dipeptidyl diazoketones.

    Objective To demonstrate the side effects of malariotherapy and to explore safe procedures in conduct of malariotherapy for human immunodeficiency virus (HIV) infected patients.Methods Twenty HIV/ acquired immunodeficiency syndrome (AIDS) patients were selected for the study of malariotherapy and were intravenously infected with Plasmodia vivax to induce therapeutic malaria. Malaria was terminated with chloroquine after 10-20 malarial febrile episodes. Clinical assessments were made before (baseline), during (malarial phase) and after (post) termination of malaria. The density of Plasmodia in peripheral blood from the HIV/AIDS patients were compared to that from HIV-negative naturally infected malarial patients who donated the blood for the therapeutically induced malaria. CD4 cell baseline levels were correlated to the severity of malarial symptoms and parasitemia.Results There were no significant differences of Plasmodium density between the HIV/AIDS patients injected with P. vivax and the HIV-negative blood donors. However, it was found that the HIV-positive patients had milder malarial symptoms and parasitemia with progressively lower CD4 cell baseline levels. All patients developed every day or every other day fever episodes with headache and shaking chill. These symptoms were well tolerated with the aid of anti-pyretic medications. Spleen and liver enlargement were seen in 15 of 20 and 4 of 20 patients respectively. Transitory liver effects with increase of serum glutamic-pyruvic transaminase were seen in 2 of 20 during malarial phase. Most patients experienced mild to medium anemia and 6 of 20 patients developed thrombocytopenia during malarial phase. All these side effects disappeared after termination of malaria or within one month thereafter. No complications occurred in these patients. Conclusions Therapeutically induced acute vivax malaria was well tolerated in 20 HIV-positive subjects who represented a range of CD4 cell levels from 1868/μl to 15/

    At the request of the U.S. Nuclear Regulatory Commission`s (NRC`s) Headquarters Office, the Environmental Survey and Site Assessment Program (ESSAP) of the Oak Ridge Institute for Science and Education (ORISE) compared the documented procedures that the U.S. Environmental Protection Agency (EPA) and ESSAP use for collecting environmental samples. The project objectives were to review both organizations` procedures applicable to collecting various sample matrices, compare the procedures for similarities and differences, and then to evaluate the reason for any identified procedural differences and their potential impact on ESSAP`s sample data quality. The procedures reviewed included those for sampling surface and subsurface soil, surface and groundwater, vegetation, air, and removable surface contamination. ESSAP obtained copies of relevant EPA documents and reviewed and prepared a tabulated summary of each applicable procedure. The methods for collecting and handling each type of sample were evaluated for differences, and where these were identified, the significance and effect of the differences on analytical quality were determined. The results of the comparison showed that, overall, the procedures and methods that EPA and ESSAP use for sample collection are very similar. The number of minor differences noted were the result of restrictions or procedures necessary to ensure sample integrity and prevent the introduction of interfering compounds when samples are to be analyzed for chemical parameters. For most radio nuclide analyses, these additional procedures are not necessary. Another item noted was EPA`s inclusion of steps that reduce the potential for sample cross-contamination by preparing (dressing) a location prior to collecting a sample or removing a portion of a sample prior to containerization.

  16. Application of the tukey trend test procedure to assess developmental and reproductive toxicity. I. Measurement data.

    Antonello, J M; Clark, R L; Heyse, J F

    1993-07-01

    Developmental and reproductive (DAR) toxicity studies typically include a series of increasing doses of a compound and a zero dose control. Given this framework, Tukey et al. (Biometrics, 41, 295-301, 1985) proposed a procedure (referred to as either the Tukey trend or TCH test procedure) for detecting a nonzero trend in response to increasing doses of the test compound. The procedure considers three candidate dosage scalings to ensure high power against relatively common dose-response patterns and appreciable power against most reasonable patterns. For toxicologic effects with near monotonic dose-response patterns, simulation studies have shown the TCH test to be overall more powerful than pairwise comparison procedures. The TCH test can be applied sequentially, eliminating the highest dose each time a statistically significant trend is observed, until a no-statistical-significance-of-trend dose is reached. This is the highest dose through which there is no statistically trustworthy evidence of the compound's impact on the response. Since DAR toxicity usually exhibits a progressive (monotonic) dose-response, we advocate routine use of Tukey's trend test for the evaluation of treatment effects in these studies. In this article, we discuss the procedure in detail and apply it to fetal body weight, a continuous measurement variable, from a developmental toxicity study.

    2001-01-01

    The number of engine-driven rotary instruments available on the market is steadily increasing. These instruments enable clinicians to prepare better shaped root canals, however, rotary instruments have a higher risk for fracture than hand instruments. Unfortunately, the stresses placed on engine-driven rotary instruments in curved canals are insufficiently studied. The aim of this study was to develop a device which could measure more accurately the physical parameters influencing rotary instruments in curved canals. For this purpose, a specially designed machine was constructed to measure the torque which develops between the rotary instrument and the motor. Apical forces and penetration depths could also be directly measured in real time. A variety of other measurements was also possible because of other special set-ups integrated into the device. In the current study torque was assessed for GT-Files, size 35 with a .12 and sizes 20 with a .12 to .06 taper. In additions to preparations in simulated canals in plastic blocks, the "ISO 3630-1 specification for fracture moment" and "number of cycles till fatigue fracture" was measured. The findings indicated that when instruments were used for preparations, torques up to 40 Nmm were present. This exceeded the static fracture load, which was less than than 13 Nmm for the size 20 with .12 taper. In contrast, the number of rotations were more than 10 times lower when shaping canals in plastic blocks with a 5 mm radius of curvature than the number of rotations to fracture in the "cyclic fatigue test". This suggests that a GT-instrument could be used in ten canals. The apical force was always greater than 1 N and occasionally, 8 N or more was recorded. Further studies on natural teeth with varying canal geometries are required using the specially developed torsional machine to reduce the incidence of instrument fracture. In this way an efficient clinical potential can be confirmed for engine-driven rotary instruments in

    Intravenous iron preparations are typically classified as non-dextran-based or dextran/dextran-based complexes. The carbohydrate shell for each of these preparations is unique and is key in determining the various physicochemical properties, the metabolic pathway, and the immunogenicity of the iron-carbohydrate complex. As intravenous dextran can cause severe, antibody-mediated dextran-induced anaphylactic reactions (DIAR), the purpose of this study was to explore the potential of various intravenous iron preparations, non-dextran-based or dextran/dextran-based, to induce these reactions. An IgG-isotype mouse monoclonal anti-dextran antibody (5E7H3) and an enzyme-linked immunosorbent assay (ELISA) were developed to investigate the dextran antigenicity of low molecular weight iron dextran, ferumoxytol, iron isomaltoside 1000, ferric gluconate, iron sucrose and ferric carboxymaltose, as well as isomaltoside 1000, the isolated carbohydrate component of iron isomaltoside 1000. Low molecular weight iron dextran, as well as dextran-based ferumoxytol and iron isomaltoside 1000, reacted with 5E7H3, whereas ferric carboxymaltose, iron sucrose, sodium ferric gluconate, and isolated isomaltoside 1000 did not. Consistent results were obtained with reverse single radial immunodiffusion assay. The results strongly support the hypothesis that, while the carbohydrate alone (isomaltoside 1000) does not form immune complexes with anti-dextran antibodies, iron isomaltoside 1000 complex reacts with anti-dextran antibodies by forming multivalent immune complexes. Moreover, non-dextran based preparations, such as iron sucrose and ferric carboxymaltose, do not react with anti-dextran antibodies. This assay allows to assess the theoretical possibility of a substance to induce antibody-mediated DIARs. Nevertheless, as this is only one possible mechanism that may cause a hypersensitivity reaction, a broader set of assays will be required to get an understanding of the mechanisms that may

    This guidance document (1) provides instructions on preparing the components of an ecological work plan to complement the overall site remedial assessment investigation/feasibility study (RI/FS) work plan and (2) directs the user on how to implement ecological tasks identified in the plan. Under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA), as amended by the Superfired Amendments and Reauthorization Act of 1986 (SARA), an RI/FS work plan win have to be developed as part of the site-remediation scoping the process. Specific guidance on the RI/FS process and the preparation of work plans has been developed by the US Environmental Protection Agency (EPA 1988a). This document provides guidance to US Department of Energy (DOE) staff and contractor personnel for incorporation of ecological information into environmental remediation planning and decision making at CERCLA sites. An overview analysis of early ecological risk assessment methods (i.e., in the 1980s) at Superfund sites was conducted by the EPA (1989a). That review provided a perspective of attention given to ecological issues in some of the first RI/FS studies. By itself, that reference is of somewhat limited value; it does, however, establish a basis for comparison of past practices in ecological risk with current, more refined methods.

    Rod-shaped mesoporous silica nanoparticles (RMSN) with built-in gold nanoparticles or thin gold nanowires in the pore channels were in situ synthesized via a one-step procedure. The insertion of a hydrophobic gold precursor into the mesopores of RMSN was reached through a micellar solubilization mechanism and gold nanoparticles were achieved through a thermal reduction. The resulting RMSN and Au-RMSN samples were characterized by using X-ray diffraction, transmission and scanning microscopies (TEM and SEM), X-ray photoelectron spectroscopy (XPS), nitrogen physisorption and solid-state Nuclear Magnetic Resonance (NMR). The interaction of Au precursor (a carbene complex) with the thiol group at the silica surface was identified and found to play a crucial role in the dispersion of the uniform metal nanoparticles at the internal surface of RMSN. Moreover, TEM micrographs revealed the absence of large gold particles outside the mesopore network. The shape of Au nanoparticles and their loading amount in the mesoporous silica could be easily tuned by altering the concentration of gold precursor.

  2. A Generic Procedure for the Assessment of the Effect of Concrete Admixtures on the Sorption of Radionuclides on Cement: Concept and Selected Results

    A screening procedure is proposed for the assessment of the effect of concrete admixtures on the sorption of radionuclides by cement. The procedure is both broad and generic, and can thus be used as input for the assessment of concrete admixtures which might be used in the future. The experimental feasibility and significance of the screening procedure are tested using selected concrete admixtures: i.e. sulfonated naphthalene-formaldehyde condensates, lignosulfonates, and a plasticiser used at PSI for waste conditioning. The effect of these on the sorption properties of Ni(II), Eu(III) and Th(IV) in cement is investigated using crushed Hardened Cement Paste (HCP), as well as cement pastes prepared in the presence of these admixtures. Strongly adverse effects on the sorption of the radionuclides tested are observed only in single cases, and under extreme conditions: i.e. at high ratios of concrete admixtures to HCP, and at low ratios of HCP to cement pore water. Under realistic conditions, both radionuclide sorption and the sorption of isosaccharinic acid (a strong complexant produced in cement-conditioned wastes containing cellulose) remain unaffected by the presence of concrete admixtures, which can be explained by the sorption of them onto the HCP. The pore-water concentrations of the concrete admixtures tested are thereby reduced to levels at which the formation of radionuclide complexes is no longer of importance. Further, the Langmuir sorption model, proposed for the sorption of concrete admixtures on HCP, suggests that the HCP surface does not become saturated, at least for those concrete admixtures tested.

    Studies performed on lipid extraction from animal and fish tissues do not provide information on its influence on fatty acid composition of the extracted lipids as well as on cholesterol content. Data presented in this paper indicate the impact of extraction procedures on fatty acid profile of fish lipids extracted by the modified Soxhlet and ASE (accelerated solvent extraction) procedure. Cholesterol was also determined by direct saponification method, too. Student's paired t-test used for comparison of the total fat content in carp fish population obtained by two extraction methods shows that differences between values of the total fat content determined by ASE and modified Soxhlet method are not statistically significant. Values obtained by three different methods (direct saponification, ASE and modified Soxhlet method), used for determination of cholesterol content in carp, were compared by one-way analysis of variance (ANOVA). The obtained results show that modified Soxhlet method gives results which differ significantly from the results obtained by direct saponification and ASE method. However the results obtained by direct saponification and ASE method do not differ significantly from each other. The highest quantities for cholesterol (37.65 to 65.44 mg/100 g) in the analyzed fish muscle were obtained by applying direct saponification method, as less destructive one, followed by ASE (34.16 to 52.60 mg/100 g) and modified Soxhlet extraction method (10.73 to 30.83 mg/100 g). Modified Soxhlet method for extraction of fish lipids gives higher values for n-6 fatty acids than ASE method (t(paired)=3.22 t(c)=2.36), while there is no statistically significant difference in the n-3 content levels between the methods (t(paired)=1.31). The UNSFA/SFA ratio obtained by using modified Soxhlet method is also higher than the ratio obtained using ASE method (t(paired)=4.88 t(c)=2.36). Results of Principal Component Analysis (PCA) showed that the highest positive impact to

    Reducing preventable deaths because of uncontrolled hemorrhage, tension pneumothorax, and airway loss is a priority. As part of a research initiative comparing different training models, this study evaluated the reliability and validity of a test that assesses combat medic performance during a polytrauma scenario using live animal models. Nine procedural checklists and seven global rating scales were piloted with four cohorts of soldiers (n = 94) at two U.S. training sites. Cohorts represented "novice" to "proficient" trainees. Procedure scores and a mean global score were calculated per subject. The intraclass correlation was calculated per procedure, with 0.70 as the threshold for acceptability. An overall difference among cohorts was hypothesized: Cohort 4 (proficient) > Cohort 3 (competent) > Cohort 2 (beginners) > Cohort 1 (novice) trainees. Data were analyzed using Kruskal-Wallis and analysis of variance. At Site A, intraclass correlation coefficients ranged from 74% to 93% for 6 of 9 procedures. Cohorts differed significantly on hemorrhage control, needle decompression, cricothyrotomy, amputation management, chest tube insertion, and mean global scores. Cohort 4 outperformed the others, and Cohorts 2 and 3 outperformed Cohort 1. The test differentiates novices from beginners, competent, and proficient trainees on difficult procedures and overall performance.

    Full Text Available Introduction: The aim of this study was to make a comparison between microleakage of conventionally restored class V cavities using bur and acid etchant and, the ones prepared and conditioned by Er:YAG laser. Materials and Methods: 30 recently extracted intact caries and filling free human permanent molars were used for this study. Then, Cold cure acrylic resin was used to seal the apices. The samples were randomly assigned to 5 groups of six each. Class V cavities were prepared one on buccal and one on lingual surface of each sample. Group 1: cavity preparation by diamond bur and turbine + acid etch, Group 2: cavity preparation by Er:YAG laser + acid etch, Group 3: cavity preparation by Er:YAG laser + Laser etching, Group 4: cavity preparation by diamond bur and turbine + laser etching, Group 5: cavity preparation by Er:YAG laser with no conditioning procedure. The cavities restored with restorative composite resin. Samples were then immersed in 2% methylene blue solution for 24 hours. The data were then analyzed using Wilcoxon signed ranks test and Kruskal-Wallis statistical tests. Results: The Kruskal Wallis test showed a significant difference (P < 0.05 between enamel and cementum margin microleakage, while the higher microleakage was related to the cementum margin of restorations. Conclusion: There was no significant difference in evaluating microleakeage degree of cavities prepared by Er:YAG laser and diamond bur.

    We used whole-body plethysmography to investigate the effect of restraint, ear marking, tail vein and retroorbital blood sampling, and tail clipping on respiration in Balb/c × TCR-HA+/– F1 hybrid mice (F1h). Baseline values of breathing parameters were determined. During the experiment, mice experienced a procedure and then plethysmographic recordings were obtained immediately and at 4, 24, and 48 h afterward. Baseline breathing parameters showed significant differences between sexes. Restraint affected minute volume differently than did handling in male mice and to a lesser extent in female mice. Ear marking significantly changed minute volume compared with handling but not restraint in male mice and in the opposite manner in female mice. Tail vein blood sampling changed minute volume in a significant manner compared with restraint but not compared with handling in both sexes. Retroorbital blood sampling significantly changed minute volume compared with values for both handling and restraint in male mice but only compared with handling in female mice. Tail clipping modified minute volume significantly compared with handling in male mice and compared with restraint in both sexes. Analysis of data showed that routine procedures affect minute volume in mice depending on invasiveness of maneuver and in a sex-biased manner for as long as 24 h after the procedure. Our experiment shows that procedures performed on laboratory mice can change respiratory parameters and can be investigated by plethysmography. PMID:23043813

    A truly practical lab-on-a-chip (LOC) system for point-of-care testing (POCT) hepatotoxicity assessment necessitates the embodiment of full-automation, ease-of-use and "sample-in-answer-out" diagnostic capabilities. To date, the reported microfluidic devices for POCT hepatotoxicity assessment remain rudimentary as they largely embody only semi-quantitative or single sample/gene detection capabilities. In this paper, we describe, for the first time, an integrated LOC system that is somewhat close to a practical POCT hepatotoxicity assessment device - it embodies both tissue sample preparation and multiplex real-time RT-PCR. It features semi-automation, is relatively easy to use, and has "sample-in-answer-out" capabilities for multiplex gene expression analysis. Our tissue sample preparation module incorporating both a microhomogenizer and surface-treated paramagnetic microbeads yielded high purity mRNA extracts, considerably better than manual means of extraction. A primer preloading surface treatment procedure and the single-loading inlet on our multiplex real-time RT-PCR module simplify off-chip handling procedures for ease-of-use. To demonstrate the efficacy of our LOC system for POCT hepatotoxicity assessment, we perform a preclinical animal study with the administration of cyclophosphamide, followed by gene expression analysis of two critical protein biomarkers for liver function tests, aspartate transaminase (AST) and alanine transaminase (ALT). Our experimental results depict normalized fold changes of 1.62 and 1.31 for AST and ALT, respectively, illustrating up-regulations in their expression levels and hence validating their selection as critical genes of interest. In short, we illustrate the feasibility of multiplex gene expression analysis in an integrated LOC system as a viable POCT means for hepatotoxicity assessment.

    The detailed structural characterization of the metal function of two fully formulated Ni-W hydrocracking catalysts was investigated by time resolved in situ X-ray absorption spectroscopy (EXAFS and XANES) at both the Ni K-edge and W L{sub 3}-edge, and by high resolution transmission electron microscopy. These two hydrocracking catalysts (designated as HCA and HCB) contained the same wt% of Ni and W, the same wt% of the other constituents ({gamma}-Al{sub 2}O{sub 3}/silico-aluminate), and were calcined at the same temperature, but were prepared by different methods in order to highlight the sensitivity of the characterization techniques to the structural differences. The morphology of the WS{sub 2} particles in the sulfided catalyst is substantially different between the two catalysts: in the HCA catalyst there are many more particles with multiple WS{sub 2} layers whereas in HCB there are more single layers. The average diameter of the WS{sub 2} plates is similar in both. The catalysts show a difference in the amount of W sulfidation after the 410 C sulfidation treatment in 10% H{sub 2}S/H{sub 2}. The W of HCA catalyst was completely sulfided whereas 16% W of HCB catalyst was unsulfided. Similarly there is a difference in the amount of sulfided Ni: 16% Ni in HCA and 60% Ni in HCB remain unsulfided. In the sulfided form of both catalysts the Ni exists in three different morphologies: oxidized Ni (six-fold coordinate as a nickel aluminate), nanoparticulate Ni{sub 3}S{sub 2}, and Ni decorating the edge sites of the WS{sub 2}. In both the Ni{sub 3}S{sub 2}, and Ni decorating the edge sites of the WS{sub 2}, the Ni is in a tetrahedral coordination with sulfur. In both catalysts the sulfidation of the Ni and W occurs essentially simultaneously over most of the temperature range and the sulfidation of the W proceeds through the same tungsten oxysulfide in both samples. The characterization methodology presented here is a powerful one for elucidating the structural

    A new concept of using thin-layer chromatography to sample preparation for the quantitative determination of solute/s followed by instrumental techniques is presented Thin-layer chromatography (TLC) is used to completely separate acetaminophen and its internal standard from other components (matrix) and to form a single spot/zone containing them at the solvent front position (after the final stage of the thin-layer chromatogram development). The location of the analytes and internal standard in the solvent front zone allows their easy extraction followed by quantitation by HPLC. The exctraction procedure of the solute/s and internal standard can proceed from whole solute frontal zone or its part without lowering in accuracy of quantitative analysis.

    The influences of preparation conditions of Al-5Ti-B (as-cast and hot-rolled) and Al-10Sr (as-cast and hotextruded) and melt treatment procedures on the grain refinement and modification performance of A356 alloy are experimentally studied. For the two master alloys, the 50% reduction is sufficient to meet the demands of the efficient grain refinement and modification of A356 alloy. When Al-5Ti-B is introduced into the melt prior to degassing, the grain refinement efficiency of Al-5Ti-B will be greatly increased due to the better dispersity of TiB2 particles. Al-5Ti-B master alloy is less prone to affect the modification effect of Al-10Sr when they are used together.

    Enamel cutting using dental handpieces is a critical process in tooth preparation for dental restorations and treatment but the machinability of enamel is poorly understood. This paper reports on the first quantitative assessment of the enamel machinability using computer-assisted numerical control, high-speed data acquisition, and force sensing systems. The enamel machinability in terms of cutting forces, force ratio, cutting torque, cutting speed and specific cutting energy were characterized in relation to enamel surface orientation, specific material removal rate and diamond bur grit size. The results show that enamel surface orientation, specific material removal rate and diamond bur grit size critically affected the enamel cutting capability. Cutting buccal/lingual surfaces resulted in significantly higher tangential and normal forces, torques and specific energy (penamel machinability for clinical dental practice.

    2016-06-01

    OpenStreetMap (OSM) is the largest spatial database of the world. One of the most frequently occurring geospatial elements within this database is the road network, whose quality is crucial for applications such as routing and navigation. Several methods have been proposed for the assessment of OSM road network quality, however they are often tightly coupled to the characteristics of the authoritative dataset involved in the comparison. This makes it hard to replicate and extend these methods. This study relies on an automated procedure which was recently developed for comparing OSM with any road network dataset. It is based on three Python modules for the open source GRASS GIS software and provides measures of OSM road network spatial accuracy and completeness. Provided that the user is familiar with the authoritative dataset used, he can adjust the values of the parameters involved thanks to the flexibility of the procedure. The method is applied to assess the quality of the Paris OSM road network dataset through a comparison against the French official dataset provided by the French National Institute of Geographic and Forest Information (IGN). The results show that the Paris OSM road network has both a high completeness and spatial accuracy. It has a greater length than the IGN road network, and is found to be suitable for applications requiring spatial accuracies up to 5-6 m. Also, the results confirm the flexibility of the procedure for supporting users in carrying out their own comparisons between OSM and reference road datasets.

    Conization for suspected high grade cervical intraepithelial neoplasia (CIN) is often performed based on abnormal cytology only. Loop electrosurgical excision procedure (LEEP) is a very common technique in this context. The present study analyses the accuracy of preoperative assessment of CIN with cytology plus colposcopic biopsy and assesses the efficacy of LEEP for the treatment of CIN. Two-hundred and sixty-six consecutive patients treated with LEEP for suspected CIN at our center were retrospectively analyzed. Cytology, HPV-DNA testing, colposcopically directed cervical biopsy and/or endocervical curettage were performed to assess cervical lesions before and 3-6 months after surgery. Median age of the patients was 34 years. Median follow-up was 50 months. Preoperative HPV testing was positive for high risk types in 77.9%. All patients underwent LEEP without further ablative procedures. Complete excision of the lesion could be achieved in 84.3%; in 13.5% margins were not securely cleared and in 2.2% the lesion was not excised entirely. Overall complication rate was 5.4% (mainly postoperative bleeding and pain). Overall concordance of colposcopic biopsy and cone histology was 85.8%. The concordance rate was higher for CIN 2/3 (95.1%) compared with CIN 1 (63.2%). Nine patients (3.4%) had persistent disease after 3 months, 4 (1.5%) developed disease recurrence and underwent re-conization. HPV testing at 3-6 months after surgery was negative in 78.5%; 2 of the patients developing disease recurrence had a persistent HPV infection after surgery. Assessment of cervical lesions with colposcopic biopsy is an accurate method (concordance with cone histology 85.8%). Surgical treatment of high grade CIN with LEEP is a safe procedure with low recurrence rates, resulting in a clearance of cervical HPV infection in the majority of cases.

    Full Text Available Requirements definition is a fundamental activity within information systems development. Social and organisational issues are at the centre of many of the problems experienced during the development and implementation of information systems, and these need to be explored during requirements definition. The NIAM Conceptual Schema Design Procedure (CSDP is a method for identifying and describing information requirements using fact types. This paper discusses some limitations of the information requirements definition step of the CSDP which result from its lack of focus on the socio-organisational dimension of information systems development. Four different approaches to exploring the socio-organisational contexts of systems are discussed. It is proposed that one of these, viewpoint development, be incorporated into the NIAM CSDP to provide a means of exploring and understanding a system's socio organisational context and to ensure that contextual information is a major input to the requirements definition process. This results in an enhanced design procedure. Future and current research areas are identified.

    Full Text Available Bulgaria is in a leading position concerning morbidity and mortality rate from cerebrovascular disease (CVD. The goal of this research was to examine, follow up and assess the recovery and the ability for food preparation and feeding in patients with CVD.Materials and methods: Sixty one patients were included in the research. All of them underwent physical rehabilitation program, based on their individual status. The program included: kinesitherapy, labour-therapy [(occupational therapy (OT and activities of daily life (ADL]; electrotherapy. The patients were assessed twice: in the beginning and at the end of the rehabilitation course. They self evaluated the basic parameters nevertheless which of the limbs was particularly affected. Wilcoxon rank test was used for the statistical analysis of non parametrical data and distribution. Results and analysis: At the end of the rehabilitation course the Wilcoxon’s curves were found shifted to the right, which confirmes improvement of the main parameter (self independence in the main task set to be fulfilled, no matter which limb was paretic.Conclusion: Early initiation of the rehabilitation course including labour activities and elements of ADL, given as instructions is essential for achieving better results in the rehabilitation of patients with CVD and for enhancing the self service ability. Functional OT stimulates the independence of patients and facilitates their recovering to independent everyday life and social activities.

    The aim of this study was to evaluate dental students' opinions regarding the utilization of a new grading software program for student self-assessment and a faculty-grading tool in a preclinical course. Using surface mapping technology, this program, called E4D Compare, yields a digital model of a student's preparation that is color-coded to show deficient areas. The program has now been used for two years at the James B. Edwards College of Dental Medicine at the Medical University of South Carolina, and the students previously assessed with E4D Compare have now entered into the dental clinics. For this study, students were asked to complete an anonymous survey for the investigators to evaluate students' attitudes and opinions on the effectiveness of this software in their preclinical courses to determine if this type of feedback helped them develop clinical skills. The survey also sought to collect students' opinions on the traditional objective criteria-based grading system. The survey was distributed to all members of the Classes of 2014 and 2015; it yielded a 59 percent response rate for the two classes, with a total of eighty-one students responding. Overall, the majority of students preferred the E4D Compare grading system over traditional hand-grading methods. The grading system provided instant, objective, and visual feedback that allowed students to easily see where their deficiencies were and encouraged them to work towards an ideal final product.

    A revised core curriculum for medical ethics and law in UK medical schools has been published. The General Medical Council requires medical graduates to understand law and ethics and behave in accordance with ethical and legal principles. A parallel policy agenda emphasises accountability, the development of professionalism and patient safety. Given the renewed focus on teaching and learning law alongside medical ethics and the development of professional identity, this survey aimed to identify how medical schools are responding to the preparation of medical students for practice in the future. Questions were asked about the location, content and methods of teaching and assessment of law in undergraduate medical education. Examples of course documentation were requested to illustrate the approaches being taken. A 76% response rate was achieved. Most responding schools integrate law teaching with medical ethics, emphasising both the acquisition of knowledge and its application in a clinical context. Teaching, learning and assessment of law in clinical attachments is much less formalised than that in non-clinical education. Coverage of recommended topic areas varies, raising questions about the degree to which students can embed their knowledge and skills in actual practice. More positively, teaching does not rely on single individuals and clear descriptions were offered for problem-based and small group case-based learning. Further research is required to explore whether there are optimum ways of ensuring that legal knowledge, and skills in its use, form part of the development of professionalism among doctors in training.

    Best practice guidelines for adolescents considering bariatric surgery recommend a pre-operative mental health evaluation. However, only general information about these assessments appears in the literature, which makes consistency of administration challenging. This review proposes a specific empirically-derived format for pre-surgical mental health evaluations and summarizes currently available data on the psychiatric functioning of adolescents seeking bariatric surgery. Studies of mental health evaluations for adults preparing for bariatric surgery are reviewed, as is the limited literature relevant to adolescent evaluations. A specific and detailed example of an evaluation (clinical interview, self-report questionnaires, cognitive assessment) used for younger patients at a major metropolitan hospital center is presented, followed by data from an initial group of adolescents completing this evaluation. 200 adolescents (n=139 female; age: 14-18 y, BMI: 35.4-83.3 kg/m(2)) presenting for bariatric surgery. A notable subset of adolescents reported current Axis I conditions (31.5%) and current mental health treatment (29.5%), but reports of current illicit drug use (1.5%) and regular alcohol use (0.5%) were relatively rare. Procedures for using the completed evaluation and post-surgery monitoring of psychosocial issues are discussed. Adolescents considering weight loss surgery should receive comprehensive pre-surgical mental health evaluations, but additional data are needed to develop specific recommendations the use of these evaluations in post-operative care.

    Dental problems are a common complaint in emergency departments in the United States. There are a wide variety of dental issues addressed in emergency department visits such as dental caries, loose teeth, dental trauma, gingival infections, and dry socket syndrome. Review of the most common dental blocks and dental procedures will allow the practitioner the opportunity to make the patient more comfortable and reduce the amount of analgesia the patient will need upon discharge. Familiarity with the dental equipment, tooth, and mouth anatomy will help prepare the practitioner for to perform these dental procedures.

  12. The Quality Evaluation Method of Instrument Flight Procedure Design Scheme Based on Fuzzy Linguistic Assessments

    Directory of Open Access Journals (Sweden)

    2013-07-01

    Full Text Available The quality of Instrument Flight Procedure Design Scheme (QIFPDS is directly related to the terminal area airspace capacity, quality, efficiency of air traffic management, and even the safety of aircraft. Hence, the evaluation of QIFPDS has great significance in real life. However, the evaluation of QIFPDS in real work is mainly done by experts through their specific knowledge and experience, which usually leads to a bias result and inevitably contains subjectivity and arbitrary defects. In this paper, a multi-attribute group decision-making method is proposed. This method makes full use of evaluation information; objectively and effectively evaluate QIFPDS. Also in this paper, a mathematical model for this method is introduced and a detailed step to solve this model is listed. At the end of this paper, an example is given to show the effectiveness and feasibility of the method.

    The dynamic range of plasma protein abundance, ranging from milligrams to picograms per milliliter, makes characterization of this proteome nearly impossible with current analytical methods. Plasma preprocessing by high-abundance protein depletion may concomitantly remove important diagnostic information. This article describes an original chromatographic procedure to isolate proteins bound to human serum albumin (HSA). Using HSA as an "affinity agent", we significantly improved the detection and identification of HSA ligands by two-dimensional liquid chromatography tandem mass spectrometry (2D LC-MS/MS). Some of the characterized species were not previously reported in published blood databases. Albumin-binding proteins may be classified as belonging to several putative functional categories and span a wide variety of predicted physiological functions.

    Aspergillus fumigatus spores in food may represent an infectious risk for neutropenic patients. We examined the efficiency of disinfection procedures applicable to foods for eradication of A fumigatus. Boiling and microwave treatment fully decontaminated an experimental spore suspension and naturally contaminated liquid foods (reconstituted dried food, herbal tea). Full decontamination of experimentally contaminated surfaces was only obtained with 70% ethanol or heating at 220 degrees C for 15 minutes. Pepper was decontaminated when heated for 15 minutes at 220 degrees C but not by microwaving. Fruit skin was partially decontaminated by 70% ethanol. We conclude that A fumigatus spores can be eradicated from food by heating to a temperature of at least 100 degrees C. When foods cannot be exposed to high temperature or microwaving, ethanol only partially reduces the level of surface contamination.

    The purpose of this study was to understand the true cost of administering prophylactic antibiotics postoperatively to patients undergoing cleft lip and lip adhesion procedures for which the rate of infection is historically low. Using time-driven activity-based costing (TDABC) methodologies, the plastic surgery department of one hospital created a process map with related time intervals and personnel cost rates for administering the antibiotic. The cost for each provider, based on standard salary information, was multiplied by the time required to complete his or her stage of the process, and this outcome was added to the supply costs. Overall cost was determined by summing the cost of all the steps. The cost of administering four doses of ampicillin/sulbactam to a patient during an inpatient stay ranged from $61.91 to $81.83. The total cost included all steps, from the initial antibiotic prescription through the final administration by a nurse. We attributed variations in cost to the staff member's level of familiarity with the antibiotic and dosing protocols for that patient. Over the course of a year, the cost of administering prophylactic antibiotics for this patient population was between $3,281.23 and $4,336.99. The results of this study effectively demonstrate the use of TDABC to determine the cost of administering prophylactic postoperative antibiotics. If we assume that antibiotics are of limited value for all clean-contaminated plastic surgery procedures, the plastic surgery department can expect to save $18,000 to $22,000 each year by forgoing their use. Furthermore, when clinically supported, reducing the use of prophylactic antibiotics not only diminishes the cost of care but also reduces the complexity of postoperative care.

    While vegetables are often studied as one food group, global measures may mask variation in the types and forms of vegetables preferred by different individuals. To explore preferences for and perceptions of vegetables, we assessed main food preparers based on their preparation of eight specific vegetables and mushrooms. An online self-report survey. Ontario, Canada. Measures included perceived benefits and obstacles of vegetables, convenience orientation and variety seeking in meal preparation. Of the 4517 randomly selected consumers who received the invitation, 1013 responded to the survey (22·4 % response). Data from the main food preparers were analysed (n 756). Latent profile analysis indicated three segments of food preparers. More open to new recipes, the 'crucifer lover' segment (13 %) prepared and consumed substantially more Brussels sprouts, broccoli and asparagus than the other segments. Although similar to the 'average consumer' segment (54 %) in many ways, the 'frozen vegetable user' segment (33 %) used significantly more frozen vegetables than the other segments due to higher prioritization of time and convenience in meal preparation and stronger 'healthy=not tasty' perception. Perception of specific vegetables on taste, healthiness, ease of preparation and cost varied significantly across the three consumer segments. Crucifer lovers also differed with respect to shopping and cooking habits compared with the frozen vegetable users. The substantial heterogeneity in the types of vegetables consumed and perceptions across the three consumer segments has implications for the development of new approaches to promoting these foods.

    This paper exposes a new methodological approach to solve the problem of intercalibrating river quality national methods when a common metric is lacking and most of the countries share the same Water Framework Directive (WFD) assessment method. We provide recommendations for similar works in future concerning the assessment of ecological accuracy and highlight the importance of a good common ground to make feasible the scientific work beyond the intercalibration. The approach herein presented was applied to highly seasonal rivers of the Mediterranean Geographical Intercalibration Group for the Biological Quality Element Macrophytes. The Mediterranean Group of river macrophytes involved seven countries and two assessment methods with similar acquisition data and assessment concept: the Macrophyte Biological Index for Rivers (IBMR) for Cyprus, France, Greece, Italy, Portugal and Spain, and the River Macrophyte Index (RMI) for Slovenia. Database included 318 sites of which 78 were considered as benchmarks. The boundary harmonization was performed for common WFD-assessment methods (all countries except Slovenia) using the median of the Good/Moderate and High/Good boundaries of all countries. Then, whenever possible, the Slovenian method, RMI was computed for the entire database. The IBMR was also computed for the Slovenian sites and was regressed against RMI in order to check the relatedness of methods (R(2)=0.45; p<0.00001) and to convert RMI boundaries into the IBMR scale. The boundary bias of RMI was computed using direct comparison of classification and the median boundary values following boundary harmonization. The average absolute class differences after harmonization is 26% and the percentage of classifications differing by half of a quality class is also small (16.4%). This multi-step approach to the intercalibration was endorsed by the WFD Regulatory Committee. © 2013 Elsevier B.V. All rights reserved.

    2010-01-22

    An automated, simple and sensitive method based on selective pressurized liquid extraction (SPLE) was developed for the analysis of polycyclic aromatic hydrocarbons in sewage sludge samples. The new sample preparation procedure consists of on-line clean-up by inclusion of sorbents in the extraction cell, and combines elevated temperatures and pressures with liquid solvents to achieve fast and efficient removal of target analytes from complex sewage sludge matrices. The effects of various operational parameters (e.g. sample pretreatment, extraction solvent, temperature, pressure, static time, etc.) on the performance of SPLE procedure were carefully investigated, obtaining the best results when SPLE conditions were fixed at 140 degrees C, 1500 psi, static time of 5 min and n-hexane as extraction solvent. A new programmed temperature vaporization-gas chromatography-tandem mass spectrometry method based on large volume injection (PTV-LVI-GC-MS/MS) was also developed and analytical determinations were performed by high performance liquid chromatography coupled with fluorescence detection and GC-MS/MS. The extraction yields for the different compounds obtained by SPLE ranged from 84.8% to 106.6%. Quantification limits obtained for all of these studied compounds (between 0.0001 and 0.005 microg g(-1), dry mass) were well below the regulatory limits for all compounds considered. To test the accuracy of the SPLE technique, the optimized methodology was applied to the analysis of a certified reference material (sewage sludge (BCR088)) and a reference material (sewage sludge (RTC-CNS312-04)), with excellent results.

    2016-01-01

    Full Text Available Solar cells based on kesterite-type Cu2ZnSnS4 (CZTS thin films were fabricated using a chemical route to prepare the CZTS films, consisting in sequential deposition of Cu2SnS3 (CTS and ZnS thin films followed by annealing at 550 °C in nitrogen atmosphere. The CTS compound was prepared in a one-step process using a novel chemical procedure consisting of simultaneous precipitation of Cu2S and SnS2 performed by diffusion membranes assisted CBD (chemical bath deposition technique. Diffusion membranes were used to optimize the kinetic growth through a moderate control of release of metal ions into the work solution. As the conditions for the formation in one step of the Cu2SnS3 compound have not yet been reported in literature, special emphasis was put on finding the parameters that allow growing the Cu2SnS3 thin films by simultaneous precipitation of Cu2S and SnS2. For that, we propose a methodology that includes numerical solution of the equilibrium equations that were established through a study of the chemical equilibrium of the system SnCl2, Na3C6H5O7·2H2O, CuCl2 and Na2S2O3·5H2O. The formation of thin films of CTS and CZTS free of secondary phases grown with a stoichiometry close to that corresponding to the Cu2SnS3 and Cu2ZnSnS4 phases, was verified through measurements of X-ray diffraction (XRD and Raman spectroscopy. Solar cell with an efficiency of 4.2%, short circuit current of 16.2 mA/cm2 and open-circuit voltage of 0.49 V was obtained.

    The Beerkan Estimation of Soil Transfer parameters (BEST) procedure represents a very attractive method to accurately and quickly obtain a complete hydraulic characterization of the soil (Lassabatère et al., 2006). However, further investigations are needed to check the prediction reliability of soil water retention curve (Castellini et al., 2016). Four soils with different physical properties (texture, bulk density, porosity and stoniness) were considered in this investigation. Sites of measurement were located at Palermo University (PAL site) and Villabate (VIL site) in Sicily, Arborea (ARB site) in Sardinia and in Foggia (FOG site), Apulia. For a given site, BEST procedure was applied and the water retention curve was estimated using the available BEST-algorithms (i.e., slope, intercept and steady), and the reference values of the infiltration constants (β=0.6 and γ=0.75) were considered. The water retention curves estimated by BEST were then compared with those obtained in laboratory by the evaporation method (Wind, 1968). About ten experiments were carried out with both methods. A sensitivity analysis of the constants β and γ within their feasible range of variability (0.110.1016/j.geoderma.2015.08.006 Lassabatère, L., Angulo-Jaramillo, R., Soria Ugalde, J.M., Cuenca, R., Braud, I., Haverkamp, R., 2006.

    Full Text Available Abstract Permanent middle cerebral artery (MCA occlusion (pMCAO by electrocoagulation is a commonly used model but with potential traumatic lesions. Early MRI monitoring may assess pMCAO for non-specific brain damage. The surgical steps of pMCAO were evaluated for traumatic cerebral injury in 22 Swiss mice using diffusion and T2-weighted MRI (7T performed within 1 h and 24 h after surgery. Temporal muscle cauterization without MCA occlusion produced an early T2 hyperintensity mimicking an infarct. No lesion was visible after temporal muscle incision or craniotomy. Early MRI monitoring is useful to identify non-specific brain injury that could hamper neuroprotective drugs assessment.

    Full Text Available This paper considers and asserts the need to obtain the results of inspection of a building at the stage of its commissioning in order to apply comprehensive methodology for assessing its residual life. The author proposes to build regression relationship by correlating the levels of the time series dynamics of stress at certain points of the object calculation scheme considering the results of subsequent surveys. It allows estimating the wear rate of structural elements. The assessment of the reliability and durability of the building frame in a deterministic form is based on the limit states method. The application of this method allows taking into account the random nature of not only the combination of existing loads, but also the strength properties of construction materials by creating a system of safety factors.

    The zero maze is an unconditioned anxiety test for mice, in which a number of environmental variables can modify the anxiety levels of the animals. In the present study, we have assessed how individual housing, handling procedure and interaction between individual housing and handling procedure affect the baseline anxiety of mice. Thirty-seven wild type mice and eighteen Tg2576 mice were used (obtained from crossing APPSWE hemizygous male C57BL6/SJL background with C57BL6/SJL female). Wild type mice were randomly assigned to four experimental groups: 1) group housed and unhandled, 2) group housed but handled, 3) individually housed, unhandled, and 4) individually housed and handled. In turn, Tg2576 mice were randomly assigned to two experimental groups: 1) individually housed, unhandled, and 2) individually housed and handled. The results show that individually housed mice exhibited more anxiety-related behaviors over a 5 min testing period than the other experimental groups. Use of the handling procedure was associated with a statistically significant reduction in anxiety-related behaviors among individually housed mice. No effects on anxiety-related behavior levels were observed when group housed animals were handled. When activity levels were significantly increased, a new parameter, "Time by Entries", helped to prevent activity from influencing anxiety parameters such as time in the open section of the zero maze test. This knowledge can help to design more efficient experiments without bias from data obtained by means of unconditioned tests.

    2014-03-01

    Full Text Available By the amendment of the Act on Public Finance of 26 July 2013, Polish legislature made a temporary suspension – till the end of 2013 – of the application of the provisions governing the Ist prudential procedure. This procedure has a crucial meaning for reducing the growth of budget deficit and in consequence – reducing public debt growth. In case of such crucial provisions for public finance, any amendments should be carried out in situations really justified and exceptional as well as with careful respecting of principles of proper legislation. In these aspects mentioned amendment rises a number of objections. For example, rapid pace of parliamentary works causes doubts about correctness of the legislative process. Therefore, in this article the author tries to make a legal assessment of the amendment of the Act on Public Finance of 26 July 2013, both from the formal and legal point of view and taking into the consideration the importance of provisions governing the prudential procedure for whole sphere of Polish public finance.

    2012-08-01

    Full Text Available The objective was to systematically review the literature to identify and grade tools used for the end point assessment of procedural skills (e.g., phlebotomy, IV cannulation, suturing competence in medical students prior to certification. The authors searched eight bibliographic databases electronically – ERIC, Medline, CINAHL, EMBASE, Psychinfo, PsychLIT, EBM Reviews and the Cochrane databases. Two reviewers independently reviewed the literature to identify procedural assessment tools used specifically for assessing medical students within the PRISMA framework, the inclusion/exclusion criteria and search period. Papers on OSATS and DOPS were excluded as they focused on post-registration assessment and clinical rather than simulated competence. Of 659 abstracted articles 56 identified procedural assessment tools. Only 11 specifically assessed medical students. The final 11 studies consisted of 1 randomised controlled trial, 4 comparative and 6 descriptive studies yielding 12 heterogeneous procedural assessment tools for analysis. Seven tools addressed four discrete pre-certification skills, basic suture (3, airway management (2, nasogastric tube insertion (1 and intravenous cannulation (1. One tool used a generic assessment of procedural skills. Two tools focused on postgraduate laparoscopic skills and one on osteopathic students and thus were not included in this review. The levels of evidence are low with regard to reliability – κ = 0.65–0.71 and minimum validity is achieved – face and content. In conclusion, there are no tools designed specifically to assess competence of procedural skills in a final certification examination. There is a need to develop standardised tools with proven reliability and validity for assessment of procedural skills competence at the end of medical training. Medicine graduates must have comparable levels of procedural skills acquisition entering the clinical workforce irrespective of the country of

  15. Students’ self-efficacy and cognitive assessment of stress in the situation of exam preparation and taking

    2012-01-01

    Full Text Available The first goal of this research is to explore the relationship between self-efficacy in exam preparation and taking and the outcomes of cognitive assessment of stress in an exam situation, whereby the influence of the variable assessed current stress level is kept under control. The second goal is to determine whether there are differences and which of them largely discriminate the students of private and state-owned faculties with respect to the studied variables. Three instruments were used. The outcomes of cognitive assessment of stress were measured by the Measure of Cognitive As­sessment of Stress questionnaire. Self-efficacy in exam preparation and taking was measured by the Scale of Self-Efficacy in Exam Preparation and Taking. The as­sessed current level of stress in students was measured by the Inventory of Students’ Recent Life Experiences. The research included 272 students (153 female and 119 male. The most important finding of the research is that self-efficacy significantly correlates with several outcomes of cognitive assessment of stress, such as: threats, general controllability, personal control and stress level. The second important re­search finding is that students of private faculties largely perceive exam situation as a challenge, assessing that they have higher personal control and self-efficacy level in the process of exam preparation and taking.

  16. Assessment of alternate procedures for the seismic analysis of multiply supported piping systems

    1985-06-01

    When response spectrum methods are used in the seismic analysis of piping systems the response due to inertial action, the dynamic response, and the response due to the time varying differential motions of the support points (the pseudo-static response) must be determined. In this study the adequacy and the degree of conservatism associated with the uniform response spectrum method, the center of mass response spectrum method and fourteen variants of the independent response spectrum method to compute the dynamic response and five different methods to compute the pseudo-static response were evaluated. For this purpose a sample of six piping systems, two of which were subjected to thirty-three earthquakes, were studied. For each system and seismic excitation a multiple independent support excitation time history analysis was developed and used to provide a best estimate of true response and to form the basis for comparison. A combination procedure to calculate the total responses is considered as well. Results are presented and compared to the corresponding responses evaluated using the current uniform response spectrum method and the center of mass response spectra approach. Based on the results, recommendations concerning the use of the methods were developed.

    The discovery of offshore fields in ultra deep water and the presence of reservoirs located in great depths below the seabed requires innovative solutions for offshore oil production systems. Many riser configurations have emerged as economically viable technological solutions for these scenarios. Therefore the study and the development of methodologies applied to riser design and procedures to calculate and to dimension production risers, taken into account the effects of mete ocean conditions, such as waves, current and platform motion in the fatigue failure is fundamental. The random nature of these conditions as well as the mechanical characteristics of the riser components are critical to a probabilistic treatment to ensure the greatest reliability for risers and minimum risks associated to different aspects of the operation like the safety of the installation, economical concerns and the environment. The current work presents a procedure of the identification and the assessment of main parameters of risk when considering fatigue failure. Static and dynamic behavior of Steel Catenary Riser (SCR) under the effects of mete ocean conditions and uncertainties related to total cumulative damage (Miner-Palmgren's rule) are taken into account. The methodology adopted is probabilistic and the approach is analytical. The procedure is based on the First Order Reliability Method (FORM) which usually presents low computational effort and acceptable accuracy. The procedure suggested is applied for two practical cases, one using data available from the literature and the second with data collected from an actual Brazilian offshore field operation. For both cases, results of the probability of failure due to fatigue were obtained for different locations along the SCR length connected to a semi-submersible platform. From these results, the sensitivity of the probability of failure due to fatigue for a SCR could be verified, and the most effective parameter could also be

  20. Using Procedure Based on Item Response Theory to Evaluate Classification Consistency Indices in the Practice of Large-Scale Assessment

    Directory of Open Access Journals (Sweden)

    Shanshan Zhang

    2017-09-01

    Full Text Available In spite of the growing interest in the methods of evaluating the classification consistency (CC indices, only few researches are available in the field of applying these methods in the practice of large-scale educational assessment. In addition, only few studies considered the influence of practical factors, for example, the examinee ability distribution, the cut score location and the score scale, on the performance of CC indices. Using the newly developed Lee's procedure based on the item response theory (IRT, the main purpose of this study is to investigate the performance of CC indices when practical factors are taken into consideration. A simulation study and an empirical study were conducted under comprehensive conditions. Results suggested that with negatively skewed distribution, the CC indices were larger than with other distributions. Interactions occurred among ability distribution, cut score location, and score scale. Consequently, Lee's IRT procedure is reliable to be used in the field of large-scale educational assessment, and when reporting the indices, it should be treated with caution as testing conditions may vary a lot.

    Microwave-assisted acid decomposition and oil-in-water emulsification were evaluated as sample pretreatment procedures to determine Al, Ba, Mo, Si and V in lubricating oils by high-resolution continuum source flame atomic absorption spectrometry (HR-CS FAAS). Average recoveries of Al, Ba and V in oil digests (107, 103 and 101%) were close to those obtained for emulsions prepared in kerosene medium (94, 113 and 95%). Average recoveries for Mo were close to 105 and 46% for emulsions and digests, respectively. Improved average recoveries (101%) were obtained for Mo in digests using the analyte addition technique. Silicon was successfully quantified only in digested samples. Limits of quantification for Al, Ba, Mo and V were 1.4, 31.5, 1.5 and 11.4-fold lower than those obtained by line-source FAAS. Enhanced sensitivity, multi-elemental capability, and high sample throughput are among the main advantages of HR-CS FAAS in comparison with the line-source FAAS technique.

    Performing an interventional procedure imposes a commitment on interventional radiologists to conduct the initial patient assessment, determine the best course of therapy, and provide long-term care. Patient care before and after an interventional procedure, identification, and management of early and delayed complications of various procedures are equal in importance to the procedure itself. In this second part, we complete the comprehensive, methodical review of pre-procedural care and patient preparation before vascular and interventional radiology procedures.

    This study was to verify the usefulness of Nanovid microscopy techniques for evaluating induced modifications in bovine spermatozoal membranes. Frozen thawed bovine sperm were labeled with 20-nm colloidal gold particles bound to concanavalin A (ConA) or heparin ligands. Sperm membrane changes were induced in vitro by capacitating and acrosome-reacting procedures. Capacitation was induced by incubation with 10 micrograms/ml of heparin for 4 hours at 37 degrees C, 5% CO2, and high humidity. Membrane changes associated with the acrosome reaction were induced by addition of lysophosphatidylcholine (100 micrograms/ml) and incubation for 15 minutes at 37 degrees C, 5% CO2, and high humidity. Gray intensity (black = 0; white = 255) of sperm (ONCELL) and background (OFFCELL) were evaluated with computer-enhanced videomicroscopy with either differential interference contrast (DIC) or Nanovid optics. A high gold concentration on a membrane region produced blacker video pictures with Nanovid microscopy. Gray intensity of video pictures of a region with little or no gold would have a gray intensity equal to or greater than that of the background, that is, toward white. Weighted least squares methods were used to analyze ONCELL data using OFFCELL as a covariate. In experiment 1, ONCELL intensities of cells labeled with ConA-gold complex were lower than those labeled with heparin-gold at the same treatment level. In experiment 2, ONCELL intensity decreased as the concentration of heparin-gold increased from 0 to 0.041 microgram/microliter heparin. ONCELL intensity significantly decreased after sperm were treated with the highest heparin-gold level and acrosome reacted.(ABSTRACT TRUNCATED AT 250 WORDS)

    A feasibility study for producing a matrix reference material for selected polycyclic aromatic hydrocarbons (PAHs) in baby food is reported. A commercially available baby food, containing carrots, potatoes, tomato, white beans and meat, was spiked with the so-called 15 + 1 PAHs included in the PAHs priority list for food of the EU, at a mass fraction level of 1 μg/kg. The contaminated baby food was further processed by autoclaving, freezing or freeze drying. The homogeneity of the three materials (bottle-to-bottle variation) and their short-term (4 weeks) and long-term (18 months) stability at different temperatures were assessed. To this end, an analytical method based on a solid-liquid extraction followed by cleaning up with gel permeation chromatography (GPC) and solid phase extraction (SPE) and GC-IDMS determination, was validated in-house. It could be demonstrated that the procedure fulfilled the demands for application to the homogeneity and isochronous stability studies for the candidate reference materials targeted here. All three materials proved to be sufficiently homogeneous for the intended use. Measurements on the autoclaved material provided the most promising results in terms of envisaged shelf life, although freeze drying was also found to be a suitable processing technique for most of the investigated PAHs. These results are an important step towards the development of a matrix reference material for PAHs in a processed food matrix in a presentation very similar to routine samples.

    Objective Apical deviations are important factors in endodontic therapy, since they can cause the treatment failure. The aim of the present study was to determine the centering capacity of ProTaper Universal™, Twisted File™ and Revo-S® rotary systems using cone beam computed tomography analysis before and after the instrumentation of root canals. Materials and Methods Thirty mesiobuccal roots from human lower first molars were divided into three groups of ten: Group 1 - ProTaper Universal™ Rotary System; Group 2 - Twisted File™ Rotary System; and Group 3 - Revo-S® Rotary System. All teeth were scanned using computed tomography to determine the condition of the root canal before and after instrumentation (4mm, 3mm and 2mm from the root apex). Images were made using ICAT VISION software for both instrumented and non-instrumented canals. Results The results were analyzed statistically using the Kolmogorov-Smirnov normality test for quantitative variables. Comparisons were made with two groups (Mann-Whitney - abnormal) and with more than two groups (Kruskal Wallis - abnormal). The level of significance was set at pProTaper Universal” and “Twisted File” systems. For the Twisted File system, a statistically significant difference was recorded between the measurements of 4mm and 3 mm. Conclusion None of the assessed instruments was completely effective in terms of the biomechanical preparation of root canals since all created deviation from the original anatomy of the canal.

    The past research reports in the area of safety engineering proposed the Computer-aided HAZOP system to be applied to Nuclear Reprocessing Facilities. Automated HAZOP system has great advantage compared with human analysts in terms of accuracy of the results, and time required to conduct HAZOP studies. This report surveys the literature on risk assessment and safety design based on the concept of independent protection layers (IPLs). Furthermore, to improve HAZOP System, counter measures information related to abnormal situation in plants are added to knowledge base in the system. As the result the HAZOP system can give appropriate measures information to protect accidents to uses. Such HAZOP system is applied to analyze the processes, where the ability of the proposed system is verified. (author)

    In order to assess the susceptibility of the quantum key distribution (QKD) systems to the hacking attack including simultaneous and frequent system self-decalibrations, we analyze the stability of the QKD transmission organized in two commercially available systems. The first one employs non-entangled photons as flying qubits in the dark quantum channel for communication whereas the second one utilizes the entangled photon pairs to secretly share the cryptographic key. Applying standard methods of the statistical data analysis to the characteristic indicators of the quality of the QKD communication (the raw key exchange rate [RKER] and the quantum bit error rate [QBER]), we have estimated the pace of the self-decalibration of both systems and the repeatability rate in the case of controlled worsening of the dark channel quality.

  16. Assessment of the embryo quality in the procedure of in vitro fertilization

    Directory of Open Access Journals (Sweden)

    Bjelica Artur

    2016-01-01

    Full Text Available Introduction. Since reproductive technologies are becoming increasingly popular among the couples with infertility problem, and having in mind that the success rate is still low, the clinicians tend to transfer more embryos in order to increase the probability of success. However, such a strategy increases the risk of multiple pregnancy, which brings about numerous risks to the health of both the mother and children. Therefore, an elective single-embryo transfer is set as imperative, which, on the other hand, would not be possible without selection and evaluation of the quality of embryos. Assessment of Embryo Quality. Embryos can be selected by various methods, from non-invasive to invasive methods. In non-invasive methods, the embryos are selected by their morphology or by the techniques based on the analysis of molecular components - analyses of the level of proteomes or metabolomes. A more detailed monitoring of the kinetics of the embryo development can be related to the introduction of time-lapse imaging and monitoring systems into laboratory practice. The invasive methods encompass the techniques such as preimplantation genetic diagnosis and preimplantation genetic screening. In preimplantation genetic diagnosis, the assisted reproduction technologies cycle is approached for the genetic reasons, whereas preimplantation genetic screening is used to enhance the success rate of the assisted reproduction cycles. Conclusion. In this paper we have shown that the application of elective single-embryo transfer requires the selection and assessment of the quality of embryos by the methods that have been developed in the last four decades, and still need further improvements.

    The objective is to present a new methodology to assess quantitatively the impact of bar removal on the anterior chest wall, among patients with pectus excavatum who have undergone the Nuss procedure, and present a preliminary study using this methodology. We propose to acquire, for each patient, the surface of the anterior chest wall using a three-dimensional laser scanner at subsequent time points (short term: before and after surgery; long term: follow-up visit, 6months, and 12months after surgery). After surfaces postprocessing, the changes are assessed by overlapping and measuring the distances between surfaces. In this preliminary study, three time points were acquired and two assessments were performed: before vs after bar removal (early) and before vs 2-8weeks after bar removal (interim). In 21 patients, the signed distances and volumes between surfaces were computed and the data analysis was performed. This methodology revealed useful for monitoring changes in the anterior chest wall. On average, the mean, maximum, and volume variations, in the early assessment, were -0.1±0.1cm, -0.6±0.2cm, and 47.8±22.2cm(3), respectively; and, in the interim assessment, were -0.5±0.2cm, -1.3±0.4cm, and 122.1±47.3cm(3), respectively (pmethodology is novel, objective and safe, helping on follow-up of pectus excavatum patients. Moreover, the preliminary study suggests that the time the bar was in situ may be the main determinant of the anterior chest wall retraction following bar removal. Further studies should continue to corroborate and reinforce the preliminary findings, by increasing the sample size and performing long-term assessments. III. Copyright © 2017 Elsevier Inc.

  18. Procedures for assessment of cumulative impacts of coal mining on the hydrologic balance

    Science.gov (United States)

    Lumb, Alan M.

    1982-01-01

    Techniques were developed to assess the probable cumulative impacts of anticipated surface mining upon the hydrology of and area. An activity profile of cumulative drainage area versus river miles downstream from the surface mining site is constructed that shows major water uses, flood prone areas, and stream classifications. From the summary shown by the activity profile, an impact matrix is used as a checklist for the importance of the impacts under categories such as water supply, flood prone areas, water contact recreation, etc. Based on the categories checked on the impact matrix, a simple, less accurate model or a more comprehensive and accurate one can be used to quantify the impacts. Quantified impacts are then displayed on an impact profile showing the percentage change in a hydrologic characteristic versus distance downstream of the surface mining site. The simple model for quantification considers only dilution from tributary areas during critical periods whereas the comprehensive model routes flows and quality of water continuously through the year and considers, in addition to dilution, instream processes such as settling, biological uptake , and chemical reactions.

  19. Mapping the good faith principle in international investment arbitration: Assessment of its substantive and procedural value

    Directory of Open Access Journals (Sweden)

    Đajić Sanja

    2012-01-01

    Full Text Available International investment cases show the frequent use of good faith arguments by both investors and respondent states. These cases also illustrate how parties and tribunals tend to conceptualize the good faith principle which has become an important rule of international investment law. This article will explore recent trends in order to assess the importance of this argument for both parties and at different stages of the proceeding. This article will also provide an overview of responses given by the tribunals faced with good faith arguments. Whereas claimants have traditionally relied on this concept to argue the breach of fair and equitable treatment and legitimate expectations, recent cases such as Inceysa, Phoenix and TSA Spectrum, indicate a new defense strategy for respondent states. Given the fact that investment tribunals have shown willingness to treat the good faith principle as autonomous and as a self-standing standard, the possibilities for respondent states have increased. Respondent states can rely on good faith to deny the right of claimants to seize the tribunal (Article 41(5 of the ICSID Rules, to challenge the jurisdiction of the tribunal or admissibility, to contest the right of the claimant to have a decision in its favor, or to challenge the right to compensation.

    A truncation process aims to determine among the set of minimal cut-sets (MCS) produced by a probabilistic safety assessment (PSA) model which of them are significant. Several truncation processes have been proposed for the evaluation of the probability of core damage ensuring a fixed accuracy level. However, the evaluation of new risk indicators as importance measures requires to re-examine the truncation process in order to ensure that the produced estimates will be accurate enough. In this paper a new truncation process is developed permitting to estimate from a single set of MCS the importance measure of any basic event with the desired accuracy level. The main contribution of this new method is to propose an MCS-wise truncation criterion involving two thresholds: an absolute threshold in addition to a new relative threshold concerning the potential probability of the MCS of interest. The method has been tested on a complete level 1 PSA model of a 900 MWe NPP developed by 'Electricite de France' (EDF) and the results presented in this paper indicate that to reach the same accuracy level the proposed method produces a set of MCS whose size is significantly reduced.

    In this research, we introduce Social Identity Mapping (SIM) as a method for visually representing and assessing a person's subjective network of group memberships. To provide evidence of its utility, we report validating data from three studies (two longitudinal), involving student, community, and clinical samples, together comprising over 400 participants. Results indicate that SIM is easy to use, internally consistent, with good convergent and discriminant validity. Each study also illustrates the ways that SIM can be used to address a range of novel research questions. Study 1 shows that multiple positive group memberships are a particularly powerful predictor of well-being. Study 2 shows that social support is primarily given and received within social groups and that only in-group support is beneficial for well-being. Study 3 shows that improved mental health following a social group intervention is attributable to an increase in group compatibility. In this way, the studies demonstrate the capacity for SIM to make a contribution both to the development of social-psychological theory and to its practical application.

    Particle image velocimetry (PIV) provides a field of discrete vectors to represent a continuum velocity field. Various methods have been adopted to evaluate the integrity of the discrete vectors. In contrast, the present communication provides a systematic technique whereby the integrity of the measured field can be assessed using basic topological principles. Starting with the recognition that PIV provides a vector field overlaid on a planar surface, the analyst can identify the holes (to be punched through the surface of a sphere) and the handles (to be added to the sphere’s surface) that will represent the appropriate surface for the topological analysis. These operations define the a priori Euler characteristic (χ A ) for the subject PIV image. The experimental Euler characteristic (χ E ) will be known from the properties of the measured vector field: nodes, saddles, etc. A necessary condition for the integrity of the measured vector field is that χ E   =  χ A . The topological bases for the integrity evaluation, including the important constraint of ensuring a smooth collapsed sphere, are carefully explained and described with examples.

    Full Text Available CONTEXT AND OBJECTIVES: Endometrial cancer is the most prevalent type of malignant neoplasia of the genital tract. The objective of this study was to calculate the sensitivity, specificity, accuracy and positive and negative predictive values for diagnostic hysteroscopy, in comparison with histopathological tests, for all lesions of the endometrial cavity. DESIGN AND SETTING: Retrospective descriptive study at the public tertiary-level university hospital of Faculdade de Medicina de Ribeirão Preto, Universidade de São Paulo. METHODS: Diagnostic hysteroscopy was indicated in the following instances: endometrial thickness > 4 mm in asymptomatic patients; postmenopausal bleeding; and irregular endometrium or endometrium difficult to assess from ultrasound, with or without vaginal bleeding. Ultrasound evaluations were carried out no more than three months prior to hysteroscopy. RESULTS: There were 510 patients, with a mean age of 61.1 ± 2.0 years and mean time elapsed since the menopause of 12.7 ± 2.5 years. Endometrial biopsies were performed on 293 patients (57.5%. Histopathological analysis showed that 18 patients presented endometrial carcinoma or typical or atypical hyperplasia, and none of them presented endometrial thickness of less than 8 mm. No significant differences were found between the median thicknesses of the various benign lesions (p > 0.05. In our data, the sensitivity, specificity, accuracy and positive and negative predictive values for cancer or hyperplasia were 94.4%, 97.0%, 96.8%, 68% and 99.6%, respectively. CONCLUSIONS: Our results suggest that hysteroscopy is valuable as a diagnostic tool for malignant/hyperplastic and benign lesions, except for submucous myomas, for which the sensitivity was only 52.6%.

    Risk assessment due to radon exposure indoors is based on annual average indoor radon activity concentration. To assess the radon exposure in a building, measurement is generally performed during at least two months during heating period in order to be representative of the annual average value. This is because radon presence indoors could be very variable during time. This measurement protocol is fairly reliable but may be a limiting in the radon risk management, particularly during a real estate transaction due to the duration of the measurement and the limitation of the measurement period. A previous field study defined a rapid methodology to characterize radon entry in dwellings. The objective of this study was at first, to test this methodology in various dwellings to assess its relevance with a daily test. At second, a ventilation model was used to assess numerically the air renewal of a building, the indoor air quality all along the year and the annual average indoor radon activity concentration, based on local meteorological conditions, some building characteristics and in-situ characterization of indoor pollutant emission laws. Experimental results obtained on thirteen individual dwellings showed that it is generally possible to obtain a representative characterization of radon entry into homes. It was also possible to refine the methodology defined in the previous study. In addition, numerical assessments of annual average indoor radon activity concentration showed generally a good agreement with measured values. These results are encouraging to allow a procedure with a short measurement time to be used to characterize long-term radon potential in dwellings.

    There is a need for novel anxiolytics, which are effective, but do not cause sedation, tolerance, and rebound anxiety on discontinuation. To investigate a procedure that can be used to assess these characteristics preclinically, rats were initially trained to press a lever at a high rate to obtain food. Once trained, periods of punishment were introduced in which electric shocks were superimposed. The intensity of these electric shocks was increased every 90 s from very low (0.01 mA) to sufficiently high to stop most subjects responding (0.4 mA), so that a complete rate/intensity function was obtained during each punishment period. The benzodiazepine, chlordiazepoxide, and two novel subtype-selective gamma-aminobutyric acid-A agonists, TP003 and TPA023, significantly increased response rates mildly suppressed by intermediate levels of electric shock without any effect on unpunished response rate. Two clinically anxiogenic agents, yohimbine and flumazenil, reduced the rate of punished responding. Aripiprazole and amphetamine reduced both punished and unpunished responding. Repeated treatment with diazepam 2.5 mg/kg daily for 15 days, initially markedly reduced unpunished response rates, but also increased punished response rates, an effect which became greater with repeated treatment. Abrupt cessation of diazepam treatment produced a reduction in punished responding. Diazepam (5 mg/kg daily) produced a greater reduction in unpunished responding, a smaller increase in punished responding, and a larger and longer lasting reduction in punished rates on withdrawal. In conclusion, the procedure detected anxiolytic and anxiogenic effects of drugs, and the sedative side effects, development of tolerance, and rebound-anxiety on discontinuation of a benzodiazepine. This procedure should have utility in the characterization of novel treatments of anxiety.

    2008-09-01

    Full Text Available Abstract Background Liquid chromatography coupled to mass spectrometry (LC-MS has become a prominent tool for the analysis of complex proteomics and metabolomics samples. In many applications multiple LC-MS measurements need to be compared, e. g. to improve reliability or to combine results from different samples in a statistical comparative analysis. As in all physical experiments, LC-MS data are affected by uncertainties, and variability of retention time is encountered in all data sets. It is therefore necessary to estimate and correct the underlying distortions of the retention time axis to search for corresponding compounds in different samples. To this end, a variety of so-called LC-MS map alignment algorithms have been developed during the last four years. Most of these approaches are well documented, but they are usually evaluated on very specific samples only. So far, no publication has been assessing different alignment algorithms using a standard LC-MS sample along with commonly used quality criteria. Results We propose two LC-MS proteomics as well as two LC-MS metabolomics data sets that represent typical alignment scenarios. Furthermore, we introduce a new quality measure for the evaluation of LC-MS alignment algorithms. Using the four data sets to compare six freely available alignment algorithms proposed for the alignment of metabolomics and proteomics LC-MS measurements, we found significant differences with respect to alignment quality, running time, and usability in general. Conclusion The multitude of available alignment methods necessitates the generation of standard data sets and quality measures that allow users as well as developers to benchmark and compare their map alignment tools on a fair basis. Our study represents a first step in this direction. Currently, the installation and evaluation of the "correct" parameter settings can be quite a time-consuming task, and the success of a particular method is still highly

    The understanding of the mechanisms involved in the build-up of soil organic matter (SOM) pools with long residence time is tightly linked to the comprehension of C dynamics. Organo-mineral associations are known to be strongly correlated with the accumulation of selective preserved C forms. Adsorption to minerals, as well as occlusion within aggregates, may affect SOM protection in different ways depending on its molecular structure and pedo-climatic conditions. In this research, we investigated changes in quantity and quality of SOM pools characterized by different protection mechanisms in coniferous and broadleaved forest soils, grassland soils, technosols and an agricultural soil with different organic amendments, in order to evaluate the influence of both land use and organic matter nature on physical and/or chemical stabilization of SOM. In particular, free (FR), intra-macroaggregate (MA), intra-microaggregate (MI), and mineral-associated (Min) fractions were separated in order to define physical and chemical mechanisms responsible for the SOM protection against degradation. All these SOM fractions were analyzed for organic C and total N concentration, and their stability assessed by thermogravimetric analysis (TD-TGA). Preliminary data show that, for all land uses, most of the organic C (40-60%) is found in the Min pool, followed by FR (20-40%)>MI MA. With the only exception of the FR, no significant correlations were found between the C/N ratio and a thermal stability index (H550-400/400-250) of each fraction; at the same time, a highly significant and positive correlation was found between these two parameters in all fractions isolated from agricultural soils. In particular, the thermal stability index measured in all Min fractions may be related to the more marked presence of labile compounds in this pool relative to recalcitrant compounds. Conversely, FR OM could not always represent a fresh and readily decomposable fraction.Furthermore, OM associated

    Sparse surface digitization with an optically tracked stylus for use in an organ surface-based image-to-physical registration is an established approach for image-guided open liver surgery procedures. However, variability in sparse data collections during open hepatic procedures can produce disparity in registration alignments. In part, this variability arises from inconsistencies with the patterns and fidelity of collected intraoperative data. The liver lacks distinct landmarks and experiences considerable soft tissue deformation. Furthermore, data coverage of the organ is often incomplete or unevenly distributed. While more robust feature-based registration methodologies have been developed for image-guided liver surgery, it is still unclear how variation in sparse intraoperative data affects registration. In this work, we have developed an application to allow surgeons to study the performance of surface digitization patterns on registration. Given the intrinsic nature of soft-tissue, we incorporate realistic organ deformation when assessing fidelity of a rigid registration methodology. We report the construction of our application and preliminary registration results using four participants. Our preliminary results indicate that registration quality improves as users acquire more experience selecting patterns of sparse intraoperative surface data.

    Conte, Mario; Pede, Giovanni; Sglavo, Vincenzo; Macerata, Diego

    The technical and practical suitability of lead-acid batteries for applications in vehicles with electrical drivetrains (battery-powered or hybrid electric) has been experimentally investigated in a variety of testing programmes. Under the direction and funding support of the Commission of the European Community, since early 1990s, the R&D Organisation EUCAR, a collaborative partnership of most European car manufacturers, has been conducting battery technological assessment projects, through bench tests carried out by different independent laboratories throughout Europe, using agreed test procedures. In this framework, ENEA acted as independent testing institute and tested, among others, three high power lead-acid batteries of various technologies (flat plate electrodes and spiral wound) for EV and HEV applications. In addition, different battery sizes and operating conditions have been tested at ENEA in a separate collaboration with ALTRA-IRISBUS. This paper intends to trace technological and performance improvements of high power lead-acid battery technology through the analysis of experimental data during parameter and life cycle tests, including the effects of battery sizes, charge/discharge profiles and testing procedures, with special emphasis on the reduction of the internal resistance and the variation of peak power and cycle life.

  13. Optimizing Frozen Sample Preparation for Laser Microdissection: Assessment of CryoJane Tape-Transfer System®.

    Yelena G Golubeva

    Full Text Available Laser microdissection is an invaluable tool in medical research that facilitates collecting specific cell populations for molecular analysis. Diversity of research targets (e.g., cancerous and precancerous lesions in clinical and animal research, cell pellets, rodent embryos, etc. and varied scientific objectives, however, present challenges toward establishing standard laser microdissection protocols. Sample preparation is crucial for quality RNA, DNA and protein retrieval, where it often determines the feasibility of a laser microdissection project. The majority of microdissection studies in clinical and animal model research are conducted on frozen tissues containing native nucleic acids, unmodified by fixation. However, the variable morphological quality of frozen sections from tissues containing fat, collagen or delicate cell structures can limit or prevent successful harvest of the desired cell population via laser dissection. The CryoJane Tape-Transfer System®, a commercial device that improves cryosectioning outcomes on glass slides has been reported superior for slide preparation and isolation of high quality osteocyte RNA (frozen bone during laser dissection. Considering the reported advantages of CryoJane for laser dissection on glass slides, we asked whether the system could also work with the plastic membrane slides used by UV laser based microdissection instruments, as these are better suited for collection of larger target areas. In an attempt to optimize laser microdissection slide preparation for tissues of different RNA stability and cryosectioning difficulty, we evaluated the CryoJane system for use with both glass (laser capture microdissection and membrane (laser cutting microdissection slides. We have established a sample preparation protocol for glass and membrane slides including manual coating of membrane slides with CryoJane solutions, cryosectioning, slide staining and dissection procedure, lysis and RNA extraction

    Full Text Available The electrochemical characteristics of Ti0.6Ir0.4O2/Ti and Ti0.6Ru0.4O2/Ti anodes prepared by the sol–gel procedure from the corresponding oxide sols, obtained by force hydrolysis of the corresponding metal chlorides, were compared. The voltammetric properties in H2SO4 solution indicate that Ti0.6Ir0.4O2/Ti has more pronounced pseudocapacitive characteristics, caused by proton-assisted, solid state surface redox transitions of the oxide. At potentials negative to 0.0 VSCE, this electrode is of poor conductivity and activity, while the voltammetric behavior of the Ti0.6Ru0.4O2/Ti electrode is governed by proton injection/ejection into the oxide structure. The Ti0.6Ir0.4O2/Ti electrode had a higher electrocatalytical activity for oxygen evolution, while the investigated anodes were of similar activity for chlorine evolution. The potential dependence of the impedance characteristics showed that the Ti0.6Ru0.4O2/Ti electrode behaved like a capacitor over a wider potential range than the Ti0.6Ir0.4O2/Ti electrode, with fully-developed pseudocapacitive properties at potentials positive to 0.60 VSCE. However, the impedance characteristics of the Ti0.6Ir0.4O2/Ti electrode changed with increasing potential from resistor-like to capacitor-like behavior.

    Three different procedures for sample preparation have been compared for the determination of Cu, Mo and Sb in airborne particulate matter (APM) collected on glass fiber filters using high-resolution continuum source graphite furnace atomic absorption spectrometry (HR-CS GF AAS). Direct solid sample analysis of the ground filters was compared with microwave-assisted acid leaching with aqua regia and ultrasound-assisted extraction also using aqua regia. The main absorption line at 324.754 nm or the secondary line at 216.509 nm was used for the determination of Cu, depending on the analyte content in the samples. The primary absorption line at 313.259 nm was used for Mo and the secondary line at 212.739 nm for Sb determination. The limits of detection (LOD, 3σ) found for the direct solid sampling method, based on ten atomizations of an unused filter were 15 μg g(-1) for all three analytes, corresponding to 40 ng m(-3) for a typical air volume of 1,440 m(3) collected over a period of 24h. The LOD for the other two methods were less than a factor of two inferior, but the total time required for an analysis was significantly longer. The repeatability of the measurements was between 3 and 9% (n=5), and the results obtained with the three methods did not show any significant difference. The ratio between the three analytes on the filters from areas of intense traffic was found to be around Cu:Mo:Sb≈4:1:1.4, which suggests that the source of all three elements is brake linings, i.e., related to automobile traffic. When the ratio deviated significantly from the above values, the source of contamination was assumed to be of different origin.

    Full Text Available Inadequate attention during design and construction of some of reinforced concrete (RC buildings in Cyprus has raised questions about the performance level of these existing buildings under future earthquakes. This study aimed to assess the seismic structural response of a four story existing RC building. For this purpose, first, the weak structural elements (e.g.\\ the not safety column-beam joints and weak columns were detected using linear static procedure (LSP analyses on the basis of Turkish earthquake code. Then, two different strengthening methods were examined. In the first method which is common in Cyprus, the existing building was strengthened based on LSP, using column jacketing to satisfy seismic code requirements to remove the weak elements. The second strengthening method was carried out using nonlinear static procedures (NSP to achieve the basic safety objective (BSO performance level described in FEMA 356. For existing and both strengthened structures, pushover curves were obtained and following FEMA 356, performance points were calculated and compared. The seismic responses of existing and strengthened buildings were also assessed using incremental dynamic analyses (IDA. Nonlinear dynamic time history analyses have been performed by using SDOF models of these buildings under action of different scales of 20 ground motion records. Then IDA curves for each earthquake have been constructed. Limit – states at each performance level have been defined and summarizing the multi – record IDA curves, 16%, 50% and 84% fractile curves were obtained. Since selected structure represents common existing buildings in Cyprus, probabilistic structural damage estimation fragility curves were also obtained in terms of peak ground acceleration (PGA for each considered performance level. Results showed that the strengthening method based on the NSP to satisfy the BSO requirements is much more effective than the one based on the LSP to improve

    2009-01-01

    An electronic survey was used to conduct a needs and capacity assessment of health education faculty to determine the extent to which advocacy instruction is present in undergraduate and graduate curricula in health education and to identify faculty members' needs and capacity to provide professional preparation and development experiences related to advocacy. An analysis of the results reveals that most undergraduate and graduate health education programs include advocacy instruction. Although faculty believe advocacy and instruction related to advocacy are important, many lack advocacy-related professional preparation and development experiences and do not participate in advocacy-related training initiatives and advocacy activities. There is wide variability in faculty confidence in their competence to provide advocacy instruction. Partnerships among professional organizations, health education practitioners, university faculty, individuals engaged in policy advocacy initiatives, and policy makers are needed to enhance the capacity of university faculty to provide professional preparation and development experiences related to advocacy.

  4. Screening procedure to assess the impact of urban stormwater temperature to populations of brown trout in receiving water.

    Science.gov (United States)

    Rossi, Luca; Hari, Renata E

    2007-07-01

    The discharge of urban stormwater may cause a sudden temperature increase in receiving waters that may be harmful to fish and other aquatic organisms. A screening procedure is proposed with temperature thresholds for the runoff from roofs and roads as well as for the receiving water system to protect brown trout from thermal damage. The stormwater temperature is calculated on the basis of a simple thermodynamic estimate for different latitudes. Only receiving waters with maximum daily mean temperatures of 22 degrees C (T1) are considered potential habitats for brown trout. The maximum temperature for a 1-h exposure time with a safety margin for 100% survival is 25 degrees C (T2), the sudden temperature change at the beginning of a rain event must not exceed 7 degrees C (T3), and fish-egg development requires the daily maximum temperature in winter to be below 12 degrees C (T4). Examples of stormwater runoff from roof or road surfaces from Switzerland validate our approach within +/-0.5 degrees C. Effects of runoff into receiving waters without detailed data can be predicted within +/-0.8 degrees C. With the restriction by T1, T2 seems not to be an acute problem at Swiss latitudes. T3 could play a role, especially if a large amount of runoff is discharged in small and rather cool rivers and streams. Finally, T4 deserves more attention than hitherto given. The proposed procedure may be a useful tool for assessing the influence of urban stormwater on the temperature of the receiving waters, particularly with regard to predicting the thermal impacts of urban or suburban runoff to populations of brown trout.

    A human reliability analysis (HRA) procedure is developed for a low power/shutdown probalistic safety assessment (PSA) in pressurized light water reactors. At first, the HRA procedure developed is based on the two major current methods: THERP (technique for human error rate prediction) and SHARP (systematic human action reliability procedure). Then, it focuses on the specific situation of low power and shutdown operation of pressurized light water reactors. Major characteristics of the HRA procedure are as follows; 1) The use of the work sheet developed increase the plausibility and credibility of the quantification process of human actions and enable use to trace easily it. 2) The explicit use of decision tree could partly eliminate the possible subjectiveness in human reliability analyst`s judgement used for HRA. It is expected that the HRA procedure developed allow human reliability analyst to perform a systematic and consistent HRA. (author). 26 refs., 13 tabs., 8 figs.

    Task interspersal procedures have been quite effective in increasing autistic children's motivation to learn. These procedures have typically demonstrated that the inclusion of reinforced maintenance tasks (previously learned tasks) increases responding to new acquisition tasks because more reinforcers, in general, are available. However, studies have not specifically addressed the effects of various schedules of reinforcement, used in conjunction with task interspersal procedures, upon respo...

  9. An organizational survey of the Strategic Petroleum Reserve. [Organizational survey in preparation for an upcoming Tiger Team Assessment

    Shurberg, D.A.; Haber, S.B.

    1992-01-01

    At the request of the management of the Strategic Petroleum Reserve (SPR), an Organizational Survey (OS), identical to the one that has been used prior to Tiger Team Assessments at other Department Energy facilities, was administered at SPR independent of a Tiger Team Assessment. The OS measured employees' opinions on subjects such as organizational culture, communication, commitment, group cohesion, coordination, safety, environmental issues, and job satisfaction. The result of this work was a quantitative measure of these variables at the SPR site. SPR management intends to utilize these results in their self-assessment process in preparation for an upcoming Tiger Team Assessment. This report presents these results and discusses their interpretation.

  10. Risk assessment of botanicals and botanical preparations intended for use in food and food supplements: emerging issues.

    Rietjens, Ivonne M C M; Slob, Wout; Galli, Corrado; Silano, Vittorio

    2008-08-15

    At present there is a growing interest for use of botanicals and botanical ingredients in medicines, for teas or in foods and in food supplements. In addition, a number of plant-derived food items form an integral part of regular human diets. Currently, there is an increasing awareness among safety experts and regulators of risks associated with the use of botanicals and botanical ingredients in food including food supplements. It is becoming clear that "natural" does not equal "safe" and that, in modern society, adverse health effects can occur as a result of (mis)use. With the growing awareness of these issues efforts to ensure safety of botanicals and botanical ingredients are also increasing. Several guidance documents on safety assessment of botanicals and botanical preparations to be used as ingredients in food and food supplements have been published, although, at present, relevant legislative frameworks and guidances for risk assessment are not established yet. Furthermore, when defining possible guidance documents for risk assessment of botanicals, several issues emerge that need to be developed beyond the present state-of-the-art. The present paper describes some of the issues to be considered and developed to a further extent to improve risk assessment of botanicals and botanical preparations, illustrated by examples based on some allylalkoxybenzenes. It is concluded that, for an improved and more accurate future risk assessment of botanicals, it is necessary to further develop and validate: (i) the use of the margin of exposure (MOE) concept for compounds that are both genotoxic and carcinogenic; (ii) new ways to quantify and incorporate matrix effects into risk assessment strategies; (iii) the use of analytical chemistry approaches, enabling complete chemical characterisation of complex mixtures. Defining new approaches in risk assessment would be in line with the inspiring attitude of the late Professor Robert Kroes, who, for example by supporting the

  15. Simple approach for the preparation of 15-15N2-enriched water for nitrogen fixation assessments: Evaluation, application and recommendations

    Directory of Open Access Journals (Sweden)

    Isabell eKlawonn

    2015-08-01

    Full Text Available Recent findings revealed that the commonly used 15N2 tracer assay for the determination of dinitrogen (N2 fixation can underestimate the activity of aquatic N2-fixing organisms. Therefore, a modification to the method using pre-prepared 15-15N2-enriched water was proposed. Here, we present a rigorous assessment and outline a simple procedure for the preparation of 15-15N2-enriched water. We recommend to fill sterile-filtered water into serum bottles and to add 15-15N2 gas to the water in amounts exceeding the standard N2 solubility, followed by vigorous agitation (vortex mixing ≥5 min. Optionally, water can be degassed at low-pressure (≥950 mbar for ten minutes prior to the 15-15N2 gas addition to indirectly facilitate the 15-15N2 dissolution. This preparation of 15-15N2-enriched water can be done within one hour using standard laboratory equipment. The final 15N-atom% excess was 5% after replacing 2–5% of the incubation volume with 15-15N2-enriched water. Notably, the addition of 15-15N2-enriched water can alter levels of trace elements in the incubation water due to the contact of 15-15N2-enriched water with glass, plastic and rubber ware during its preparation. In our tests, levels of trace elements (Fe, P, Mn, Mo, Cu, Zn increased by up to 0.1 nmol L-1 in the final incubation volume, which may bias rate measurements in regions where N2 fixation is limited by trace elements. For these regions, we tested an alternative way to enrich water with 15-15N2. The 15-15N2 was injected as a bubble directly to the incubation water, followed by gentle shaking. Immediately thereafter, the bubble was replaced with water to stop the 15-15N2 equilibration. This method achieved a 15N-atom excess of 6.6±1.7% when adding 2 mL 15-15N2 per liter of incubation water. The herein presented methodological tests offer guidelines for the 15N2 tracer assay and thus, are crucial to circumvent methodological draw-backs for future N2 fixation assessments.

    Full Text Available Abstract Background Standardised translation and cross-cultural adaptation (TCCA procedures are vital to describe language translation, cultural adaptation, and to evaluate quality factors of transformed outcome measures. No TCCA procedure for objectively-assessed outcome (OAO measures exists. Furthermore, no official German version of the Canadian Chedoke Arm and Hand Activity Inventory (CAHAI is available. Methods An eight-step for TCCA procedure for OAO was developed (TCCA-OAO based on the existing TCCA procedure for patient-reported outcomes. The TCCA-OAO procedure was applied to develop a German version of the CAHAI (CAHAI-G. Inter-rater reliability of the CAHAI-G was determined through video rating of CAHAI-G. Validity evaluation of the CAHAI-G was assessed using the Chedoke-McMaster Stroke Assessment (CMSA. All ratings were performed by trained, independent raters. In a cross-sectional study, patients were tested within 31 hours after the initial CAHAI-G scoring, for their motor function level using the subscales for arm and hand of the CMSA. Inpatients and outpatients of the occupational therapy department who experienced a cerebrovascular accident or an intracerebral haemorrhage were included. Results Performance of 23 patients (mean age 69.4, SD 12.9; six females; mean time since stroke onset: 1.5 years, SD 2.5 years have been assessed. A high inter-rater reliability was calculated with ICCs for 4 CAHAI-G versions (13, 9, 8, 7 items ranging between r = 0.96 and r = 0.99 (p Conclusions The TCCA-OAO procedure was validated regarding its feasibility and applicability for objectively-assessed outcome measures. The resulting German CAHAI can be used as a valid and reliable assessment for bilateral upper limb performance in ADL in patients after stroke.

    Aim of the present study was to assess impact of urban drains over river water and sediments by physico-chemical and metal analysis. Metal speciation (Sequential Extraction Procedure) and elemental composition analysis (SEM-EDS) was used to quantify metal pollution load in river sediments. Metal speciation analysis showed dominance of available and labile fractions of all heavy metals (Cr, Ni, Cu, Zn, Cd and Pb) except Mn and Fe which were dominant in residual forms. Cluster analysis (CA), Principal Components Analysis (PCA) and Partial Least Square Regression (PLSR) were applied as source receptor modeling for pollutants. Results classified river stretch into three zones i.e. moderately, severely and extremely polluted, on the basis of pollutant concentration released from anthropogenic sources. SEM-EDS study revealed the elemental composition percentage in river sediments. Pollution Load Index (PLI) varied from 1.8 (S1)-3.9 (S15). The Geo accumulation index (GAI) was found highest for Cd (6.88-8.97) and Pb (2.41-3.24).

    Oropharyngeal dysphagia is one of the major complications of stroke and a risk factor for malnutrition and prolonged in-hospital stay. The overall aim was to describe to what extent nutritional assessments (i.e. BMI kg/m(2), eating problem, and weight loss) were performed and documented in the records of older stroke patients treated with enteral nutrition by percutaneous endoscopic gastrostomy (PEG). A secondary aim was to identify documented post-procedural complications after PEG insertion during hospital stay. The study is retrospective. Data were collected from records of 161 stroke patients ≥65 years, who received PEG, admitted to three stroke units during a 4-year period. Mean age of the patients was 82.2 (±7) years, and 86% of the patients were ≥75 years old. On admission, body weight was documented in 50% of the patients and at discharge in 38% of the patients. BMI data were not documented at all at discharge in one of the units. Almost 80% of the patients fulfilled the European Network criteria for multimorbidity. Morbidity and multimorbidity correlated to the length of stay (pnutritional status was poorly recorded which could affect the patient's nutritional treatment during the hospital stay. This study indicates that implementation of guidelines in patients with stroke is needed. The high number of pressure ulcers was an unexpected finding.

    Volatile organic compounds (VOC) can affect indoor air quality through vapours released indoors by cigarette smoke, building materials, and common household solvents and cleaners. Therefore, the level of VOC contaminants might be a reliable indicator of the impact due to subsurface contamination. The following method of indirect assessment has been accepted by Canadian and American environmental regulatory bodies. This accepted method involves soil gas sampling close to the basement or ground floor slab of a building and VOC vapour transport modeling in order to estimate soil gas flow rates and VOC flux into a building. VOC flux concentration can be used to evaluate the potential human exposure to soil or groundwater derived VOCs, and to estimate the associated human health risks. This paper describes the shallow vapour sampler and sampling procedure specifically designed for collecting representative soil gas samples in the zone adjacent to a building basement or a ground floor slab, which was developed by O'Connor Associates. The results of numerical modeling, and the technical rationale behind the design of a soil gas sampling program for different soil types were presented. Soil type, depth to groundwater, and sampling well construction and their respective influence were discussed with reference to soil gas sampling programs and human health risk evaluations. 12 refs., 5 tabs., 6 figs.

    2012-10-01

    We used a quantitative microbiological risk assessment model to describe the risk of Campylobacter and Salmonella infection linked to chicken meals prepared in households in Dakar, Senegal. The model uses data collected specifically for this study, such as the prevalence and level of bacteria on the neck skin of chickens bought in Dakar markets, time-temperature profiles recorded from purchase to consumption, an observational survey of meal preparation in private kitchens, and detection and enumeration of pathogens on kitchenware and cooks' hands. Thorough heating kills all bacteria present on chicken during cooking, but cross-contamination of cooked chicken or ready-to-eat food prepared for the meal via kitchenware and cooks' hands leads to a high expected frequency of pathogen ingestion. Additionally, significant growth of Salmonella is predicted during food storage at ambient temperature before and after meal preparation. These high exposures lead to a high estimated risk of campylobacteriosis and/or salmonellosis in Dakar households. The public health consequences could be amplified by the high level of antimicrobial resistance of Salmonella and Campylobacter observed in this setting. A significant decrease in the number of ingested bacteria and in the risk could be achieved through a reduction of the prevalence of chicken contamination at slaughter, and by the use of simple hygienic measures in the kitchen. There is an urgent need to reinforce the hygiene education of food handlers in Senegal.

    The Instability Severity Index Score (ISIS) includes preoperative clinical and radiological risk factors to select patients who can benefit from an arthroscopic Bankart procedure with a low rate of recurrence. Patients who underwent an arthroscopic Bankart for anterior shoulder instability with an ISIS lower than or equal to four were assessed after a minimum of 5-year follow-up. Forty-five shoulders were assessed at a mean of 79 months (range 60-118 months). Average age was 29.4 years (range 17-58 years) at the time of surgery. Postoperative functions were assessed by the Walch and Duplay and the Rowe scores for 26 patients; an adapted telephonic interview was performed for the 19 remaining patients who could not be reassessed clinically. A failure was defined by the recurrence of an anterior dislocation or subluxation. Patients were asked whether they were finally very satisfied, satisfied or unhappy. The mean Walch and Duplay score at last follow-up was 84.3 (range 35-100). The final result for these patients was excellent in 14 patients (53.8 %), good in seven cases (26.9 %), poor in three patients (11.5 %) and bad in two patients (7.7 %). The mean Rowe score was 82.6 (range 35-100). Thirty-nine patients (86.7 %) were subjectively very satisfied or satisfied, and six (13.3 %) were unhappy. Four patients (8.9 %) had a recurrence of frank dislocation with a mean delay of 34 months (range 12-72 months). Three of them had a Hill-Sachs lesion preoperatively. Two patients had a preoperative ISIS at 4 points and two patients at 3 points. The selection based on the ISIS allows a low rate of failure after an average term of 5 years. Lowering the limit for indication to 3 points allows to avoid the association between two major risk factors for recurrence, which are valued at 2 points. The existence of a Hill-Sachs lesion is a stronger indicator for the outcome of instability repair. Level IV, Retrospective Case Series, Treatment Study.

    2007-06-01

    Genomics is expected to have significant implications for risk assessment and regulatory decision making. Since 2002, the U.S. Environmental Protection Agency (EPA) has undertaken a number of cross-agency activities to further prepare itself to receive, interpret, and apply genomics information for risk assessment and regulatory purposes. These activities include: (1) the issuance of an Interim Genomics Policy on the use of genomics information in risk assessments and decision making, (2) the release of the 2004 Genomics White Paper, which outlines potential applications and implications of genomics for EPA, and (3) the recent release of the external review draft of the Interim Guidance on Microarray-Based Assays, which outlines data submission, quality, analysis, management, and training considerations for such data. This manuscript discusses these activities and more recent follow-up activities with the aim of further communicating these efforts to the broader scientific and stakeholder community.

  6. Dose-response modeling : Evaluation, application, and development of procedures for benchmark dose analysis in health risk assessment of chemical substances

    OpenAIRE

    Sand, Salomon

    2005-01-01

    In this thesis, dose-response modeling and procedures for benchmark dose (BMD) analysis in health risk assessment of chemical substances have been investigated. The BMD method has been proposed as an alternative to the NOAEL (no-observedadverse- effect-level) approach in health risk assessment of non-genotoxic agents. According to the BMD concept, a dose-response model is fitted to data and the BMD is defined as the dose causing a predetermined change in response. A lowe...

    Silicone based impression-taking of prepared teeth followed by plaster casting is well-established but potentially less reliable, error-prone and inefficient, particularly in combination with emerging techniques like computer aided design and manufacturing (CAD/CAM) of dental prosthesis. Intra-oral optical scanners for digital impression-taking have been introduced but until now some drawbacks still exist. Because optical waves can hardly penetrate liquids or soft-tissues, sub-gingival preparations still need to be uncovered invasively prior to scanning. High frequency ultrasound (HFUS) based micro-scanning has been recently investigated as an alternative to optical intra-oral scanning. Ultrasound is less sensitive against oral fluids and in principal able to penetrate gingiva without invasively exposing of sub-gingival preparations. Nevertheless, spatial resolution as well as digitization accuracy of an ultrasound based micro-scanning system remains a critical parameter because the ultrasound wavelength in water-like media such as gingiva is typically smaller than that of optical waves. In this contribution, the in-vitro accuracy of ultrasound based micro-scanning for tooth geometry reconstruction is being investigated and compared to its extra-oral optical counterpart. In order to increase the spatial resolution of the system, 2nd harmonic frequencies from a mechanically driven focused single element transducer were separated and corresponding 3D surface models were calculated for both fundamentals and 2nd harmonics. Measurements on phantoms, model teeth and human teeth were carried out for evaluation of spatial resolution and surface detection accuracy. Comparison of optical and ultrasound digital impression taking indicate that, in terms of accuracy, ultrasound based tooth digitization can be an alternative for optical impression-taking.

  8. Comprehensive quality assessment of municipal organic waste composts produced by different preparation methods.

    Tognetti, C; Mazzarino, M J; Laos, F

    2011-06-01

    In the first part of this work, the effect of municipal organic waste (MOW) composts on plant growth was evaluated in a greenhouse trial. The treatments included soil amended with 14 different composts (prepared by shredding, adding wood shavings, cocomposting with biosolids or vermicomposting), an inorganically fertilized soil, and a control soil. All of the treatments significantly increased plant growth compared to the control, and yields of three of the amended treatments were as high as that of the inorganic fertilizer treatment. When comparing differently prepared composts to the conventional compost, it was found that cocomposting MOW with biosolids was the method which most positively influenced yields (26-41% yield increases). In the second part of this work, we evaluated the effects of the different preparation methods on compost quality, using a multivariate approach. Three main quality aspects were considered collectively in a principal component analysis: organic matter and nutrient concentrations, degradability and capacity to mineralize these nutrients, and plant growth. The model was restricted to the first and second components (PC1 and PC1) which accounted for 94% of data variance. On the resulting factorial plane, four groups were distinguished. Each of the groups was compared to the reference compost to determine quality increases or decreases. Based on this analysis, it was found that cocomposting MOW with biosolids produced the highest quality products (higher total nutrient and OM concentration, nutrient mineralization potential, and plant growth). Addition of wood shavings increased OM concentration, but reduced quality in terms of the other aspects studied. Shredding was only effective to increase product quality when it was not combined with other methods, whereas vermicomposting only increased quality when MOW was not mixed with biosolids.

    Full Text Available Development of roads through protected areas and ecological sensitive regions can have catastrophic effects on wildlife. In Iran, road construction in sensitive habitats and protected areas has been expanding during the past decades. This study focuses on the ecological impacts of Isfahan’s west ringway, which passes through Ghamishloo wildlife refuge, I.U.C.N category IV, in Isfahan Province. The key affected species of the study area goitered gazelle (Gazella subgutturosa subgutterosa, was considered for impact analysis. We used HEP (Habitat Evaluation Procedure as a habitat-based impact assessment methodology which considers habitat quality and quantity. Habitat quality was measured as habitat suitability index for the species. By literature review and field observations (293 presence points, five effective variables in habitat suitability including vegetation cover, slope, elevation, distance to water and distance to road were identified, and habitat units (HUs were derived from multiplying the HSI for goitered gazelle by the species habitat area at two times (before and after road construction. The results showed that due to the presence of the ringway, 7710 HUs for goitered gazelle have been lost. In addition, we used landscape ecology approach for quantifying landscape pattern change due to road construction and landscape metrics including NP (Number of Patches, MNN (Mean Nearest Neighbor and CONTAG (Contagion. Our results provided quantitative data on habitat loss and landscape fragmentation in Ghamishloo wildlife refuge and indicated negative impacts of the ringway on goitered gazelle populations by restricting their movement between habitat patches in this region, which presents a concern for the conservation of this vulnerable species.

    2015-09-01

    The Implicit Relational Assessment Procedure (IRAP) is a technique that is attracting a substantial body of research literature, particularly within the clinical domain. In response, the present paper outlines a meta-analysis of clinically-focused IRAP effects (N = 494) to provide the first estimate of how well such effects validate against their respective criterion variables in general. The meta-analysis incorporated clinically-focused IRAP effects from 15 studies yielding a large effect size, r¯ = .45, with a desirably narrow 95% credibility interval (.23, .67). The funnel plot and subsequent sensitivity analyses indicated that this meta-effect was not subject to publication bias. The present meta-effect is an estimate based upon an IRAP literature that is still evolving rapidly in the clinical domain, and so as per its accompanying credibility interval, all conclusions that follow are necessarily provisional even if bounded. Apart from the fact that the current meta-effect might be subject to inadvertent under- and/or over-estimations of the current literature, the present meta-effect might strengthen with further refinements of the IRAP. The current meta-effect provides the means to calculate what sample size would be required to achieve a statistical power of .80 when testing the criterion validity of clinically-focused IRAP effects using a given parametric statistic. For example, first-order Pearson correlations would hypothetically require an N of 29-37 for such purposes depending upon how conservatively over-estimation of the present meta-effect is controlled for. Overall, the IRAP compares favourably with alternative implicit measures in clinical psychology. Copyright © 2015 Elsevier Ltd. All rights reserved.

  12. Assessment of Understanding: Student Teachers' Preparation, Implementation and Reflection of a Lesson Plan for Science

    2017-05-01

    Research finds that student teachers often fail to make observable instructional goals, without which a secure bridge between instruction and assessment is precluded. This is one reason that recent reports state that teacher education needs to become better at helping student teachers to develop their thinking about and skills in assessing pupils' learning. Currently in Europe, the Lesson Study method and the Content Representation tool, which both have a specific focus on assessment, have started to address this problem. This article describes and discusses an intervention in which Lesson Study was used in combination with Content Representation in student teachers' field practice. Empirical materials from one group of student teachers were analyzed to illustrate how the student teachers worked with assessment during the planning of a lesson, how they implemented it in a research lesson, and how they used the gathered observations to make claims about assessment aims. The findings suggest that the student teachers placed greater emphasis on assessment through the intervention. However, it is also found that more attention should have been dedicated to the planning phase and that the group did not manage to keep a research focus throughout the Lesson Study process. This suggests that it properly would be beneficial with several planning sessions prior to the research lesson, as well as having an expert teacher leading the Lesson Study.

    The inconsistency of professional development (PD) in teaching for graduate teaching assistants (GTAs) is a widespread problem in higher education. Although GTAs serve an important role in retention of undergraduate science majors and in promotion of scientific literacy in nonmajors, they often lack preparation and ongoing support for teaching. Given the recent national focus on instructional quality in introductory courses, our goal was to use an online survey to identify current practices of teaching PD for biology GTAs and compare these results with the last national survey on this topic. In responses from 71 participant institutions, 96% reported some mandatory teaching preparation for biology GTAs; however, 52% of these programs required 10 or fewer hours per year. Respondents wanted to change their programs to include more pedagogical information and teaching observations with feedback to their GTAs. Programmatic self-ratings of satisfaction with GTA PD were positively correlated with the number of topics discussed during PD. Although more schools are requiring GTA PD for teaching compared with the last national survey, the lack of program breadth at many schools warrants a national conversation with regard to recent calls for improving undergraduate instruction.

    The present study investigated effect of manufacturing methods such as hot melt extrusion (HME) and spray drying (SD) on physicochemical properties, manufacturability, physical stability and product performance of solid dispersion. Solid dispersions of compound X and PVP VA64 (1:2) when prepared by SD and HME process were amorphous by polarized light microscopy, powder X-ray diffractometry, and modulated differential scanning calorimetry analyses with a single glass transition temperature. Fourier transform infrared (FT-IR) and Raman spectroscopic analyses revealed similar molecular level interactions between compound X and PVP VA64 as evident by overlapping FT-IR and FT Raman spectra in SD and HME solid dispersions. The compactibility, tabletability, disintegration and dissolution performance were similar for solid dispersions prepared by both processing techniques. Differences in material properties such as surface area, morphological structure, powder densities, and flow characteristics were observed between SD and HME solid dispersion. The SD solid dispersion was physically less stable compared to HME solid dispersion under accelerated stability conditions. Findings from this study suggest that similar product performance could be obtained if the molecular properties of the solid dispersion processed by two different techniques are similar. However differences in material properties might affect the physical stability of the solid dispersions.

    2017-01-15

    The probability of major oil accidents in Arctic seas is increasing alongside with increasing maritime traffic. Hence, there is a growing need to understand the risks posed by oil spills to these unique and sensitive areas. So far these risks have mainly been acknowledged in terms of qualitative descriptions. We introduce a probabilistic framework, based on a general food web approach, to analyze ecological impacts of oil spills. We argue that the food web approach based on key functional groups is more appropriate for providing holistic view of the involved risks than assessments based on single species. We discuss the issues characteristic to the Arctic that need a special attention in risk assessment, and provide examples how to proceed towards quantitative risk estimates. The conceptual model presented in the paper helps to identify the most important risk factors and can be used as a template for more detailed risk assessments. Copyright © 2016 The Authors.

    In the present investigation, mechanical and spectroscopic properties of glass composites have been investigated. The glass composites have been prepared by the milling technique instead of using any filler particle. Due to the presence of different alkaline earth modifiers in composites, marked difference in their strength and optical properties is observed. The band gap, Urbach energy and the extinction coefficient of the glass composites have been calculated using UV–visible spectroscopy. Moreover, the real and imaginary dielectric constants have also been calculated for all the composites in addition to the Weibull statistics and cumulative probability of failure. The results have been discussed in light of comparison between the glass composites and the individual glasses. The mechanical and optical properties indicate marked effect on the mechanical strength, band gap and Urbach energy for glass composites as compared with the individual glasses.

    Full Text Available Aim: To assess the effects of three root canal preparation techniques on canal volume and surface area using three-dimensionally reconstructed root canals in extracted human maxillary molars. Materials and Methods: Thirty extracted Human Maxillary Molars having three separate roots and similar root shape were randomly selected from a pool of extracted teeth for this study and stored in normal saline solution until used. A computed tomography scanner (Philips Brilliance CT 64-slice was used to analyze root canals in extracted maxillary molars. Specimens were scanned before and after canals were prepared using stainless steel K-Files, Ni-Ti rotary ProTaper and rotary SafeSiders instruments. Differences in dentin volume removed, the surface area, the proportion of unchanged area and canal transportation were calculated using specially developed software. Results: Instrumentation of canals increased volume and surface area. Statistical analysis found a statistically significant difference among the 3 groups in total change in volume (P = 0.001 and total change in surface area (P = 0.13. Significant differences were found when testing both groups with group III (SafeSiders. Significant differences in change of volume were noted when grouping was made with respect to canal type (in MB and DB (P < 0.05. Conclusion: The current study used computed tomography, an innovative and non destructive technique, to illustrate changes in canal geometry. Overall, there were few statistically significant differences between the three instrumentation techniques used. SafeSiders stainless steel 40/0.02 instruments exhibit a greater cutting efficiency on dentin than K-Files and ProTaper. CT is a new and valuable tool to study root canal geometry and changes after preparation in great details. Further studies with 3D-techniques are required to fully understand the biomechanical aspects of root canal preparation.

    Selection for surgical residency programmes could potentially be improved through pretraining preparation, after assessment of surgical candidates' sensorimotor skills and personality traits. Existing aviation pilot selection instruments are available to test sensorimotor skills and personality traits. This study examined selected instruments to assess medical trainees' sensorimotor skills and personality traits. Aviation's validated computer-based Computerized Pilot Aptitude and Screening System (COMPASS) and Checklist Professional Profile (CPP) were applied to 166 final year medical students during a surgical clerkship between 2013 and 2015. All trainees completed COMPASS and CPP within the prescribed 2 hours. Compared with an age-matched and gender-matched cohort of 165 pilot candidates, medical trainees scored significantly higher on eye-hand coordination (peye-hand-foot coordination (pdominance (p<0.001), ambition (p<0.001) and resilience (p<0.001). Final year medical trainees from one medical school were able to complete aviation's sensorimotor skills and personality traits selection instruments within the set time frame. They scored differently from aviation trainees on selected skills and personality traits. The applicability and utility of aviation instruments to presurgical training preparation remains to be tested. Published by the BMJ Publishing Group Limited.

    Full Text Available The aim of this study was to investigate the influence of a topically administered hygienic preparation containing a 3% ethanolic extract of Brazilian green propolis (EEP-B on oral microflora spectrum changes in a group of patients who underwent common oral surgery procedures. Two gel samples were compared: the tested gel containing an active ingredient, that is, a 3% EEP-B (gel GA, and a placebo as the negative control (gel GC. The collection of microbiological material included 14 patients requiring surgical extraction of wisdom molars and short endosseous implant installation. Clinical examinations were carried out as follow-up, that is, baseline and after 5-6 weeks’ time. During the first and subsequent assessment, swabs were taken from the mucosal surface. The number of microorganism species was found to have increased following the application of GC gel over the period of 5-6 weeks. This mainly affected Gram-positive rods and bacilli as well as Gram-negative rods. Application of the GA gel enriched with 3% EEP-B caused a profound reduction in the amount of Neisseria spp. and Bifidobacterium spp. strains. Elimination of seven species of microorganisms was observed: Streptococcus acidominimus, Streptococcus oralis, Staphylococcus epidermidis, Veillonella parvula, Bifidobacterium breve, Bifidobacterium longum, and Lactobacillus acidophilus.

    In the United National Framework Convention on Climate Change (FCCC) it is recognised that developed countries have a responsibility in assisting developing countries and countries in economic transition in building a national capacity for the development, acquisition and transfer of Climate-related Technologies (CTs). Such assistance is most likely to be successful once it is tailored to the results of a sound assessment of the country`s development needs and once the results of this assessment have been endorsed by the most important stakeholders in the country. Recent insight in the opportunities and constraints for National (technology) Needs Assessments (NNAs) as planning tool for both capacity building and technology transfer regarding Environmentally Sound Technologies (ESTs) is applied here to propose a participatory Climate Change Action Planning (CCAP) process. This participatory planning process is thought to serve the dual objective of defining a national Climate Change Action Plan (CCAP) while at the same time contributing to the creation of a broad supportive basis for its acceptance and implementation among stakeholders in the developing country.

    Our research project aimed at presenting midwifery student self-assessment of performing the role of breast cancer prevention educator. Investigations were carried out in 2011 at the Medical University of Lublin in Poland, and Katolieke Hogeschool of Kortrijk in Belgium, after obtaining approval of the ethical committee of Polish Midwives Association (III/EC/2011/PMA). The project involved a total of 155 midwifery students, made up of 95 from Poland, and 60 from Belgium. Relations between opposing characteristics were tested with Chi-square (x2) test for independent traits. To assess the dependence relation between the examined variables Pearson's corrected coefficient was used. Data base and statistics were carried out with computer software STATISTICA 9.0 (StatSoftPoland). Student knowledge on prevention against breast cancer was unsatisfactory.The students place of residence determined their self-estimation of personal knowledge of breast cancer prevention and diagnosing methods to assess the incidence of the disease, this knowledge being better with the students of Lublin. Better self-estimation in the students of Lublin of their personal knowledge on factors rising the risk of breast cancer, such as alimentation method, application of oral contraceptives and breast feeding was found than in Belgian students.

    Full Text Available Most anticancer drugs are greatly limited by the serious side effects that they cause. Doxorubicin (DOX is an antineoplastic agent, commonly used against breast cancer. However, it may lead to irreversible cardiotoxicity, which could even result in congestive heart failure. In order to avoid these harmful side effects to the patients and to improve the therapeutic efficacy of doxorubicin, we developed DOX-loaded polyethylenimine- (PEI- enhanced human serum albumin (HSA nanoparticles. The formed nanoparticles were ~137 nm in size with a surface zeta potential of ~+15 mV, prepared using 20 μg of PEI added per mg of HSA. Cytotoxicity was not observed with empty PEI-enhanced HSA nanoparticles, formed with low-molecular weight (25 kDa PEI, indicating biocompatibility and safety of the nanoparticle formulation. Under optimized transfection conditions, approximately 80% of cells were transfected with HSA nanoparticles containing tetramethylrhodamine-conjugated bovine serum albumin. Conclusively, PEI-enhanced HSA nanoparticles show potential for developing into an effective carrier for anticancer drugs.

    The aim of this study was to formulate and characterize streptomycin-loaded PLGA-alginate nanoparticles for their potential therapeutic use in Salmonella subsp. enterica ATCC 14028 infections. The streptomycin nanoparticle was prepared by solvent diffusion method, and the other properties such as size, zeta potential, loading efficacy, release kinetics, and antimicrobial strength were evaluated. The survey shows that nanoparticles may serve as a carrier of streptomycin and may provide localized antibacterial activity in the treatment of Salmonellosis. Electron microscopy showed spherical particles with indentations. The average size of the nanoparticles was 90 nm. At pH 7.2, the release kinetics of streptomycin from the nanoparticles was successfully illustrated as an initial burst defined by a first order equation that after this stage, it has a drastic tendency to obtain steady state. Nevertheless, nanoparticles showed loading efficacy nearly about 70-75 %. In addition, the tendency of concentration of streptomycin released from nanoparticles to reach antibacterial activity was similar to that of free streptomycin against PLGA-alginate, but it had threefold more antimicrobial strength in comparison with free streptomycin. This work shows the potential use of streptomycin-loaded PLGA-alginate nanoparticles and its capability.

    Food suspensions prepared by Pulsifier contained less debris and filtered 1.3x to 12x faster through hydrophobic grid membrane filters (HGMFs) than those prepared by Stomacher 400. Coliform and Escherichia coli counts made by an HGMF method yielded 84 and 36 paired samples, respectively, positive by both suspending methods. Overall counts of pulsificates and stomachates did not differ significantly for either analysis, though coliform counts by Pulsifier were significantly higher in mushrooms and significantly lower in ground pork (P = 0.05). Regression equations for log10 counts of coliform and E. coli by Pulsifier and Stomacher were: Pulsifier = 0.12 + 0.97 x Stomacher, and Pulsifier = 0.01 + 1.01 x Stomacher, respectively.

  7. Assessment of dietary intake of flavouring substances within the procedure for their safety evaluation: advantages and limitations of estimates obtained by means of a per capita method.

    Arcella, D; Leclercq, C

    2005-01-01

    The procedure for the safety evaluation of flavourings adopted by the European Commission in order to establish a positive list of these substances is a stepwise approach which was developed by the Joint FAO/WHO Expert Committee on Food Additives (JECFA) and amended by the Scientific Committee on Food. Within this procedure, a per capita amount based on industrial poundage data of flavourings, is calculated to estimate the dietary intake by means of the maximised survey-derived daily intake (MSDI) method. This paper reviews the MSDI method in order to check if it can provide conservative intake estimates as needed at the first steps of a stepwise procedure. Scientific papers and opinions dealing with the MSDI method were reviewed. Concentration levels reported by the industry were compared with estimates obtained with the MSDI method. It appeared that, in some cases, these estimates could be orders of magnitude (up to 5) lower than those calculated considering concentration levels provided by the industry and regular consumption of flavoured foods and beverages. A critical review of two studies which had been used to support the statement that MSDI is a conservative method for assessing exposure to flavourings among high consumers was performed. Special attention was given to the factors that affect exposure at high percentiles, such as brand loyalty and portion sizes. It is concluded that these studies may not be suitable to validate the MSDI method used to assess intakes of flavours by European consumers due to shortcomings in the assumptions made and in the data used. Exposure assessment is an essential component of risk assessment. The present paper suggests that the MSDI method is not sufficiently conservative. There is therefore a clear need for either using an alternative method to estimate exposure to flavourings in the procedure or for limiting intakes to the levels at which the safety was assessed.

    Homogeneous cation-exchange membranes were prepared through evaporation and phase inversion methodsusing sulfonated poly(2,6-dimethyl-1,4-phenylene oxide) (SPPO) and sulfonated polyvinylchloride as binders. The effectof polymers blend’s ratio and preparation method on structure and electrochemical properties of the prepared membraneswere evaluated. The microstructures of the membranes were investigated by scanning electron microscopy (SEM) andthe sulfonation of polyvinylchloride was confirmed by elemental analyses. Moreover, the membranes performance wasevaluated by ion-exchange capacity (IEC), fixed ion concentration, membrane potential, transport number, permselectivity,areal resistance, ionic permeability, flux of ions, current efficiency, membrane oxidative stability, mechanical properties andwater content tests. The results indicated that IEC and water content were affected by the SPPO content and microstructuresof the membranes. The results showed increased efficiency and suitable electrochemical properties for membranes preparedby the evaporation method in comparison with others. Also, Fe$_2$O$_3$ nanoparticles were synthesized at room temperature by a simple sonochemical reaction between ferric chloride and NaOH. The results revealed that the addition of different amounts of Fe$_2$O$_3$ nanoparticles to the polymeric matrix could affect the hydrophilicity and transport properties of ion-exchange membranes.

  9. An operational procedure for precipitable and cloud liquid water estimate in non-raining conditions over sea Study on the assessment of the nonlinear physical inversion algorithm

    Nativi, S; Mazzetti, P

    2004-01-01

    In a previous work, an operative procedure to estimate precipitable and liquid water in non-raining conditions over sea was developed and assessed. The procedure is based on a fast non-linear physical inversion scheme and a forward model; it is valid for most of satellite microwave radiometers and it also estimates water effective profiles. This paper presents two improvements of the procedure: first, a refinement to provide modularity of the software components and portability across different computation system architectures; second, the adoption of the CERN MINUIT minimisation package, which addresses the problem of global minimisation but is computationally more demanding. Together with the increased computational performance that allowed to impose stricter requirements on the quality of fit, these refinements improved fitting precision and reliability, and allowed to relax the requirements on the initial guesses for the model parameters. The re-analysis of the same data-set considered in the previous pap...

    Based upon limited, initial observations of wall interference corrections obtained for one airfoil test, there is a need for assessing the upstream flow direction. If there is no direct measurement then a two-pass correction procedure similar to the one described here is required. Questions have arisen pertaining to the correct interpretation of the pressure coefficients measured on the slats of a slotted tunnel wall, the interpretation of just what the calculated equivalent body encompasses or should include, and what can or should be considered as quantitative criteria for data correctability. Further studies using this modified procedure will address these questions. Hopefully, a meaningful WIAC procedure can be validated for the airfoil tests in the 0.3-m TCT.

    The effectiveness of using a Digital Imaging and Communications in Medicine (DICOM)-based interactive examination system in evaluating the readiness of first year radiology residents before taking overnight call in the emergency department (ED) was reported in part I of this article. This report describes technical aspects for the design and implementation of this system. The examination system consists of two modules: Data Collection and Image Viewing. The Data Collection module was a personal computer (PC)-based DICOM storage server based on a free public domain software package, the Mallinckrodt Central Test Node. The Image Viewing module was a Java-based DICOM viewer created using another freeware package: zDicom ActiveX component. The examination takes place once a year at the end of the first 6-month rotation. Cases selected for the examination were actual clinical cases according to the American Society of Emergency Radiology core curriculum. In the 3-hour timed examination, each resident was required to read the cases and provide clinical findings and recommendations. Upper-level residents also participated in the examination to serve as a control. Answers were scored by two staff radiologists. We have been using this examination system successfully in our institution since 2003 to evaluate the readiness of the first-year residents before they take overnight call in the ED. This report describes a step-by-step procedure for implementing this system into a PC-based platform. This DICOM viewing software is available as freeware to other academic radiology institutions. The total cost for implementing this system is approximately 2000 US dollars.

    The aim of this study was to delineate pediatric emergency medicine provider opinions regarding the importance of, and to ascertain existing processes by which practitioners maintain, the following critical procedural skills: oral endotracheal intubation, intraosseous line placement, pharmacologic and electrical cardioversion, tube thoracostomy, and defibrillation. A customized survey was administered to all members of the Listserv for the American Academy of Pediatrics Section on Emergency Medicine. Perceived importance of maintaining critical pediatric procedural skills was measured using a 5-point Likert-type scale. Secondary outcomes included presence and type of mandatory training, availability of on-site backup, and perceived barriers to maintenance of skills. Two hundred sixty-two members (25%) responded representing 106 different institutions, 70% of freestanding children's hospitals that received graduate medical education payments in 2014, and 68% of pediatric emergency medicine fellowship programs. More than 90% of respondents felt it was either very or extremely important to maintain competency for 5 of the 6 critical procedures, but no more than 49% of respondents felt that clinical care alone provided opportunity to maintain skills. The proportion of respondents indicating no mandatory training for each critical procedural skill was as follows: oral endotracheal intubation (23%), intraosseous line placement (30%), pharmacologic cardioversion (32%), electrical cardioversion (32%), tube thoracostomy (40%), and defibrillation (32%). Critical procedural skills are perceived by emergency providers who care for children as extremely important to maintain. Direct care of pediatric patients likely does not provide sufficient opportunity to maintain these skills. There are widespread deficiencies relating to mandatory maintenance of critical procedural skill training.

    Coracoid transfer to a large glenoid defect is considered an excellent method to restore the surface area of the anteroinferior glenoid. However, there is little quantitative evidence supporting whether a coracoid graft can sufficiently restore the glenoid arc. To assess whether the Latarjet procedure can sufficiently restore the surface area of the glenoid. Case series; Level of evidence, 4. A total of 44 patients who underwent a Latarjet operation for a large glenoid defect between February 2009 and July 2011 were enrolled in this study. Three-dimensional computed tomography was used to calculate the surface areas of the preoperative glenoid defect size and the reconstructed glenoid. Preoperative and postoperative clinical results also were assessed. At the last follow-up, the mean visual analog scale score for instability during motion improved significantly from 5.1 points (range, 3-10 points) preoperatively to 1.3 points (range, 0-4 points) (PLatarjet procedure, the mean surface area of the reconstructed glenoid was 706±32 mm2 (range, 639-749 mm2). Finally, postoperative glenoid defect size was 5±11 mm2 (range, 3-28 mm2; 1.5%±2% of the intact glenoid surface). The Latarjet procedure can provide satisfactory outcomes, including a low recurrence rate and reliable functional recovery. Defects at the anteroinferior glenoid were restored to nearly normal after coracoid transfer by use of the Latarjet procedure, which is an anatomically matched reconstruction. © 2015 The Author(s).

    Present study provides a novel MATLAB-based parameter estimation procedure for individual assessment of hepatic insulin degradation (HID) process from standard frequently-sampled intravenous glucose tolerance test (FSIGTT) data. Direct access to the source code, offered by MATLAB, enabled us to design an optimization procedure based on the alternating use of Gauss-Newton's and Levenberg-Marquardt's algorithms, which assures the full convergence of the process and the containment of computational time. Reliability was tested by direct comparison with the application, in eighteen non-diabetic subjects, of well-known kinetic analysis software package SAAM II, and by application on different data. Agreement between MATLAB and SAAM II was warranted by intraclass correlation coefficients ≥0.73; no significant differences between corresponding mean parameter estimates and prediction of HID rate; and consistent residual analysis. Moreover, MATLAB optimization procedure resulted in a significant 51% reduction of CV% for the worst-estimated parameter by SAAM II and in maintaining all model-parameter CV% MATLAB-based procedure was suggested as a suitable tool for the individual assessment of HID process.

    Full Text Available The quality of training conditions affects sporting success, injuries and health. The aim of the work was to present the conditions during the preparations of Polish athletes for the Summer Paralympic Games 2004-2012. The study encompassed 271 paralympians: Athens (91, Beijing (89 and London (91, competing in 13 disciplines. The research was based on a two-part questionnaire by Kłodecka-Różalska adjusted for disabled sports, and was conducted one month before each PG. Part 1 contained 20 closed-ended questions regarding conditions during preparations, while Part 2 concerned socio-demographic and sports-related data. Three levels of conditions: good, satisfactory and poor, were identified. The analysis showed that while the relationships between the athletes were good in all the preparatory periods, the co-operation with the paralympic coaches worsened. The standards of accommodation, food and sports facilities lowered. Personal orthopaedic supply was satisfactory in London; personal sporting equipment was good at all PG. The quality of medical care was the highest in London. The co-operation with physicians, physiotherapists and massage therapists was satisfactory. Consultations with the dietician were sporadic and assessed as poor. Psychological consultations were rare but satisfactory in Beijing and London. Contacts with the mass media were poor at all PG. Although combining private life, work, and education with sport was satisfactory, it was increasingly difficult to manage, particularly before London. The conditions during preparations for the PG 2004-2012 varied. Improvement was noticed only in the quality of medical care and personal orthopaedic supply.
