Sample records for adequate quality control

  1. Looking for an adequate quality criterion for depth coding

    This paper deals with 3DTV, more especially with 3D content transmission using disparity-based format. In 3DTV, the problem of measuring the stereoscopic quality of a 3D content remains open. Depth signal degradations due to 3DTV transmission will induce new types of artifacts in the final rendered views. Whereas we have some experience regarding the issue of texture coding, the issue of depth coding consequences is rather unknown. In this paper we focus on that particular issue. For that purpose we considered LDV contents (Layered Depth Video) and performed various encoding of their depth information - i.e. depth maps plus depth occlusions layers - using MPEG-4 Part 10 AVC/H.264 MVC. We investigate the impact of depth coding artifacts on the quality of the final views. To this end, we compute the correlation between depth coding errors with the quality of the synthesized views. The criteria used for synthesized views include MSE and structural criteria such as SSIM. The criteria used for depth maps include also a topological measure in the 3D space (the Hausdorff distance). Correlations between the two criteria sets are presented. Trends in function of quantization are also discussed.

  2. [Quality of Mesorectal Excision ("Plane of Surgery") - Which Quality Targets are Adequate?].

    Today, the examination of rectal cancer specimens includes the obligate macroscopic assessment of the quality of mesorectal excision by the pathologist reporting the plane of surgery. The frequency of operations in the muscularis propria plane of surgery (earlier described as incomplete mesorectal excision) is essential. The quality of mesorectal excision is important for the prognosis, especially as local recurrences are observed more frequently after operations in the muscularis propria plane of surgery. For the definition of quality targets, data of 13 studies published between 2006 and 2012, each with more than 100 patients and adequate specialisation and experience of the surgeons (5413 patients), data of the prospective multicentric observation study "Quality Assurance - Rectal Cancer" (at the Institute for Quality Assurance in Operative Medicine at the Otto-von-Guericke University at Magdeburg) from 2005 to 2010 (8044 patients) and data of the Department of Surgery, University Hospital Erlangen, from 1998 to 2011 (991 patients) were analysed. The total incidence of operations in the muscularis propria plane of surgery was 5.0 % (721/14 448). Even with adequate specialisation and experience of the surgeon, the frequency of operations in the muscularis propria plane of surgery is higher in abdominoperineal excisions than in sphincter-preserving surgery (8.4 vs. 2.8 %, p < 0.001). Thus, the quality target for the frequency of operations in the muscularis propria plane should be defined as < 5 % for sphincter-preserving procedures and as < 10 % for abdominoperineal excisions.

  3. Are image quality metrics adequate to evaluate the quality of geometric objects?

    Geometric objects are often represented by many millions of triangles or polygons, which limits the ease with which they can be transmitted and displayed electronically. This has lead to the development of many algorithms for simplifying geometric models, and to the recognition that metrics are required to evaluate their success. The goal is to create computer graphic renderings of the object that do not appear to be degraded to a human observer. The perceptual evaluation of simplified objects is a new topic. One approach has been to sue image-based metrics to predict the perceived degradation of simplified 3D models. Since that 2D images of 3D objects can have significantly different perceived quality, depending on the direction of the illumination, 2D measures of image quality may not adequately capture the perceived quality of 3D objects. To address this question, we conducted experiments in which we explicitly compared the perceived quality of animated 3D objects and their corresponding 2D still image projections. Our results suggest that 2D judgements do not provide a good predictor of 3D image quality, and identify a need to develop 'object quality metrics.'

  9. Radiation dose reduction in invasive cardiology by restriction to adequate instead of optimized picture quality.

    In this study, the cinegraphic image intensifier entrance dose level for coronary angiography was changed in four steps from dose level A (0.041 microGy frame(-1)), allowing high contrast, but coarse mottled background, to level D (0.164 microGy frame(-1)), affording high transparency and sharpness. Using this new approach throughout the course of 404 consecutive cardiac catheterizations, we reduced patient radiation exposures down to 11 to 16% of currently typical values: i.e., mean dose area products of 5.97 Gy cm2 (n = 91), 6.73 (n = 113), 8.11 (n = 91), and 8.90 (n = 109); cinegraphic dose area products of 2.34, 3.64, 4.56, and 5.49; and cinegraphic dose area products frame(-1) of 13.3, 19.8, 27.0, and 30.2 mGy cm2, for levels A, B, C, and D, respectively. The number of cinegraphic frames ranged within 168 to 182 per case. Our results show that during catheterization interventionalists should vary image intensifier entrance dose levels in accordance with documented structure, angulation, and body mass index. With the exception of cases with special requirements, lower dose levels typically guarantee an adequate image quality.

  15. Quality Leadership and Quality Control

    PubMed Central

    Badrick, Tony

    2003-01-01

    Different quality control rules detect different analytical errors with varying levels of efficiency depending on the type of error present, its prevalence and the number of observations. The efficiency of a rule can be gauged by inspection of a power function graph. Control rules are only part of a process and not an end in itself; just as important are the trouble-shooting systems employed when a failure occurs. 'Average of patient normals' may develop as a usual adjunct to conventional quality control serum based programmes. Acceptable error can be based on various criteria; biological variation is probably the most sensible. Once determined, acceptable error can be used as limits in quality control rule systems. A key aspect of an organisation is leadership, which links the various components of the quality system. Leadership is difficult to characterise but its key aspects include trust, setting an example, developing staff and critically setting the vision for the organisation. Organisations also have internal characteristics such as the degree of formalisation, centralisation, and complexity. Medical organisations can have internal tensions because of the dichotomy between the bureaucratic and the shadow medical structures. PMID:18568046

    The diet quality in yogurt consumers and non-consumers was evaluated by applying the probability of adequate nutrient intake (PANDiet) index to a sample of adults and elderly from the Italian food consumption survey INRAN SCAI 2005-06. Overall, yogurt consumers had a significantly higher mean intake of energy, calcium and percentage of energy from total sugars whereas the mean percentage of energy from total fat, saturated fatty acid and total carbohydrate were significantly (p < 0.01) lower than in non-consumers. The PANDiet index was significantly higher in yogurt consumers than in non-consumers, (60.58 ± 0.33 vs. 58.58 ± 0.19, p < 0.001). The adequacy sub-score for 17 nutrients for which usual intake should be above the reference value was significantly higher among yogurt consumers. The items of calcium, potassium and riboflavin showed the major percentage variation between consumers and non-consumers. Yogurt consumers were more likely to have adequate intakes of vitamins and minerals, and a higher quality score of the diet.

    Missing an upper limb dramatically impairs daily-life activities. Efforts in overcoming the issues arising from this disability have been made in both academia and industry, although their clinical outcome is still limited. Translation of prosthetic research into clinics has been challenging because of the difficulties in meeting the necessary requirements of the market. In this perspective article, we suggest that one relevant factor determining the relatively small clinical impact of myocontrol algorithms for upper limb prostheses is the limit of commonly used laboratory performance metrics. The laboratory conditions, in which the majority of the solutions are being evaluated, fail to sufficiently replicate real-life challenges. We qualitatively support this argument with representative data from seven transradial amputees. Their ability to control a myoelectric prosthesis was tested by measuring the accuracy of offline EMG signal classification, as a typical laboratory performance metrics, as well as by clinical scores when performing standard tests of daily living. Despite all subjects reaching relatively high classification accuracy offline, their clinical scores varied greatly and were not strongly predicted by classification accuracy. We therefore support the suggestion to test myocontrol systems using clinical tests on amputees, fully fitted with sockets and prostheses highly resembling the systems they would use in daily living, as evaluation benchmark. Agreement on this level of testing for systems developed in research laboratories would facilitate clinically relevant progresses in this field.

  6. Transmission potential and design of adequate control measures for Marburg hemorrhagic fever.

    2012-01-01

    Marburg hemorrhagic fever is rare yet among the most severe diseases affecting humans, with case fatality ratio even higher than 80%. By analyzing the largest documented Marburg hemorrhagic fever epidemic, which occurred in Angola in 2005 and caused 329 deaths, and data on viral load over time in non-human primates, we make an assessment of transmissibility and severity of the disease. We also give insight into the control of new Marburg hemorrhagic fever epidemics to inform appropriate health responses. We estimated the distribution of the generation time to have mean 9 days (95%CI: 8.2-10 days) and standard deviation 5.4 days (95%CI: 3.9-8.6 days), and the basic reproduction number to be R(0) = 1.59 (95%CI: 1.53-1.66). Model simulations suggest that a timely isolation of cases, starting no later than 2-3 days after symptoms onset, is sufficient to contain an outbreak. Our analysis reveals that Marburg hemorrhagic fever is characterized by a relatively small reproduction number and by a relatively long generation time. Such factors, along with the extremely high severity and fatality, support the rare occurrence of large epidemics in human populations. Our results also support the effectiveness of social distancing measures--case isolation in particular--to contain or at least to mitigate an emerging outbreak. This work represents an advance in the knowledge required to manage a potential Marburg hemorrhagic fever epidemic.

    Well-defined quality control (QC) processes are used to determine whether a certain procedure or action conforms to a widely accepted standard and/or set of guidelines, and are important components of any laboratory quality assurance program (Popa-Burke et al., J Biomol Screen 14: 1017-1030, 2009). In this chapter, we describe QC procedures useful for monitoring the accuracy and precision of laboratory instrumentation, most notably automated liquid dispensers. Two techniques, gravimetric QC and photometric QC, are highlighted in this chapter. When used together, these simple techniques provide a robust process for evaluating liquid handler accuracy and precision, and critically underpin high-quality research programs.

    Hemophilias are the most known inherited bleeding disorders. The challenges in the management of hemophilic children are different from those in adults: prophylaxis regimen removed the hallmark of crippling disease with lifelong disabilities; individualized regimens are being implemented in order to overcome venous access problems. Presently, at least in high-income countries, advances in treatment of hemophilia resulted in continuous improvement of the patients' quality of life and life expectancy. Inhibitors remain the most severe complication of hemophilia therapy. The treatment' compliance is the key to achieve a successful management. The patient, his family, the medical and psychological team are the players of a comprehensive care system. The current management of hemophilic children is the example of huge resource investments enabling long-term benefits in particular quality of life as a primary objective of the healthcare process.

    Monitoring the microbiological quality of water used for recreational activities is very important to human public health. Although the sanitary quality of recreational marine waters could be evaluated by standard methods, they are time-consuming and need confirmation. For these reasons, faster and more sensitive methods, such as the defined substrate-based technology, have been developed. In the present work, we have compared the standard method of membrane filtration using Tergitol-TTC agar for total coliforms and Escherichia coli, and Slanetz and Bartley agar for enterococci, and the IDEXX defined substrate technology for these faecal pollution indicators to determine the microbiological quality of natural recreational waters. ISO 17994:2004 standard was used to compare these methods. The IDEXX for total coliforms and E. coli, Colilert, showed higher values than those obtained by the standard method. Enterolert test, for the enumeration of enterococci, showed lower values when compared with the standard method. It may be concluded that more studies to evaluate the precision and accuracy of the rapid tests are required in order to apply them for routine monitoring of marine and freshwater recreational bathing areas. The main advantages of these methods are that they are more specific, feasible and simpler than the standard methodology.

    The astronomical database SIMBAD developed at the Centre de donnees astronomiques de Strasbourg presently contains 760,000 objects (stellar and non-stellar). It has the unique characteristic of being structured specifically for astronomical objects. All types of heterogeneous data (bibliographic references, measurements, and sets of identification) are connected with each object. The attributes that define quality of the database include the following. Reliability: cross-identification should not rely upon just exact values object coordinates. It also means that information attached to one simple object should be consistent. The existing data must be controlled in order to start with a reliable base and to cross-identify new data assuring the quality as data grows. Exhaustivity: delays between publication of new informations and their inclusion in the database should be as short as possible. The integrity of the database has to be maintained as data accumulates. Taking the amount of data into consideration and the rate of new data production, it is necessary to use automatic methods. One of the possibilities is to use multivariate data analysis. The factor-space is a n-dimensional relevancy space which is described by the n-axes representing a set of n subject matter headings; the words and phrases can be used to scale the axes and the documents are then a vector average of the terms within them. The application reported herein is based on the NASA-STI bibliographical database. The selected data concern astronomy, astrophysics, and space radiation (102,963 references from 1975 to 1991 included 8070 keywords). The F-space is built from this bibliographical data. By comparing the F-space position obtained from the NASA-STI keywords with the F-space position obtained from the SIMBAD references, the authors will be able to show whether it is possible to retrieve information with a restricted set of words only.

    Protein quality control functions to minimize the level and toxicity of misfolded proteins in the cell. Protein quality control is performed by intricate collaboration among chaperones and target protein degradation. The latter is performed primarily by the ubiquitin-proteasome system and perhaps autophagy. Terminally misfolded proteins that are not timely removed tend to form aggregates. Their clearance requires macroautophagy. Macroautophagy serves in intracellular quality control also by selectively segregating defective organelles (eg, mitochondria) and targeting them for degradation by the lysosome. Inadequate protein quality control is observed in a large subset of failing human hearts with a variety of causes, and its pathogenic role has been experimentally demonstrated. Multiple posttranslational modifications can occur to substrate proteins and protein quality control machineries, promoting or hindering the removal of the misfolded proteins. This article highlights recent advances in posttranslational modification-mediated regulation of intracellular quality control mechanisms and its known involvement in cardiac pathology.

    Quality control measures for aviation gasoline, and some of the differences between quality control on avgas and mogas are discussed. One thing to keep in mind is that with motor gasoline you can always pull off to the side of the road. It's not so easy to do in an airplane. Consequently, there are reasons for having the tight specifications and the tight quality control measures on avgas as compared to motor gasoline.

    We analyzed the Mexican legal framework, identifying the vectors that characterize quality and control in gastrointestinal surgery. Quality is contemplated in the health protection rights determined according to the Mexican Constitution, established in the general health law and included as a specific goal in the actual National Development Plan and Health Sector Plan. Quality control implies planning, verification and application of corrective measures. Mexico has implemented several quality strategies such as certification of hospitals and regulatory agreements by the General Salubrity Council, creation of the National Health Quality Committee, generation of Clinical Practice Guidelines and the Certification of Medical Specialties, among others. Quality control in gastrointestinal surgery must begin at the time of medical education and continue during professional activities of surgeons, encouraging multidisciplinary teamwork, knowledge, abilities, attitudes, values and skills that promote homogeneous, safe and quality health services for the Mexican population.

    The term quality assurance (QA) refers to the quality control activities related to analytical procedures performed in the clinical microbiology laboratory. QA should include both external and internal quality assessment. Application of quality control tools in molecular microbiology assays is crucial to ensure the accuracy of results and appropriate patient management. External quality control is used for laboratory intercomparisons, detection of random and systematic errors, evaluation of the suitability of some reagents or commercial diagnostic kits, and continuing education. The External Quality Control Program of the Spanish Society of Infectious Diseases and Clinical Microbiology includes quality control procedures for molecular microbiology, as well as specific programs for quantitative determination of the viral load of human immunodeficiency virus type 1 (HIV-1) and hepatitis C virus (HCV), two highly important molecular markers in clinical settings due to their prognostic value and utility as a treatment guide. Internal quality control allows random and systematic errors to be detected through the inclusion of quality control samples in the assays performed in the laboratory, equipment monitoring, and audit. Evaluation of all molecular microbiology assays before their inclusion in the daily routine work of the laboratory is of utmost importance.

  4. Vigorous cleaning and adequate ventilation are necessary to control an outbreak in a neonatal intensive care unit.

    An outbreak of Bacillus cereus (B. cereus) bacteremia occurred in our neonatal intensive care unit (NICU) in July 2005. Many strains of B. cereus were cultured from patient specimens, as well as from environmental samples such as the surfaces of instruments and air in the NICU. Some of these strains were analyzed by pulsed field gel electrophoresis, and several were confirmed to be identical. We speculated that the bacterial load in the environment had initially increased and then possibly spread throughout the NICU facility via the airflow of the ventilation system. For this reason, besides maintaining standard precautions, we performed a vigorous clean of the NICU, and covered the vents to prevent dust falling from them. These protective measures ended the outbreak. In the hospital environment, adequate ventilation is important, especially in single-occupancy isolation rooms and operating theaters. However, the criteria for the adequate ventilation of multioccupancy rooms for acute care environments such as the NICU have not yet been defined. We need to pay more attention to these environmental factors in order to avoid cross contamination and infectious outbreaks.

    The current situation of plant extract in domestic and international market was analyzed in the paper. The quality control of 20 plant extracts which have reasonably good sales in USA market was compared and analyzed. The analysis of the quality control of six plant extracts indicated that there were two main reasons leading to the varied quality specifications among different suppliers. One reason was that the plant species utilized by different companies were different. The other reason was that the extraction processes were different among different production plants. Comparing with the significant international suppliers of plant extracts, the product quality of Chinese companies were not satisfactory. It was suggested that chromatography and chromatographic fingerprint techniques should be applied to improve the quality control standard of plant extract in our country.

  3. Enhancement of Bacillus subtilis Lipopeptide Biosurfactants Production through Optimization of Medium Composition and Adequate Control of Aeration.

    PubMed

    2011-01-01

    Interest in biosurfactants has increased considerably in recent years, as they are potentially used in many commercial applications in petroleum, pharmaceuticals, biomedical, and food processing industries. Since improvement of their production was of great importance to reduce the final coast, cultural conditions were analyzed to optimize biosurfactants production from Bacillus subtilis SPB1 strain. A high yield of biosurfactants was obtained from a culture of B. subtilis using carbohydrate substrate as a carbon source; among carbohydrates, glucose enhanced the best surfactin production. The optimum glucose concentration was 40 g/L. Higher amount of biosurfactants was obtained using 5 g/L of urea as organic nitrogen source and applying C/N ratio of 7 with ammonium chloride as inorganic nitrogen source. The highest amount of biosurfactants was recorded with the addition of 2% kerosene. Moreover, it was shown, using an automated full-controlled 2.6 L fermenter, that aeration of the medium, which affected strongly the growth regulated biosurfactants synthesis by the producing cell. So that, low or high aerations lead to a decrease of biosurfactants synthesis yields. It was found that when using dissolved oxygen saturation of the medium at 30%, biosurfactants production reached 4.92 g/L.

  4. Statistical process control for radiotherapy quality assurance.

    PubMed

    Pawlicki, Todd; Whitaker, Matthew; Boyer, Arthur L

    2005-09-01

    Every quality assurance process uncovers random and systematic errors. These errors typically consist of many small random errors and a very few number of large errors that dominate the result. Quality assurance practices in radiotherapy do not adequately differentiate between these two sources of error. The ability to separate these types of errors would allow the dominant source(s) of error to be efficiently detected and addressed. In this work, statistical process control is applied to quality assurance in radiotherapy for the purpose of setting action thresholds that differentiate between random and systematic errors. The theoretical development and implementation of process behavior charts are described. We report on a pilot project is which these techniques are applied to daily output and flatness/symmetry quality assurance for a 10 MV photon beam in our department. This clinical case was followed over 52 days. As part of our investigation, we found that action thresholds set using process behavior charts were able to identify systematic changes in our daily quality assurance process. This is in contrast to action thresholds set using the standard deviation, which did not identify the same systematic changes in the process. The process behavior thresholds calculated from a subset of the data detected a 2% change in the process whereas with a standard deviation calculation, no change was detected. Medical physicists must make decisions on quality assurance data as it is acquired. Process behavior charts help decide when to take action and when to acquire more data before making a change in the process.

  5. Quality control of EUVE databases

    The publicly accessible databases for the Extreme Ultraviolet Explorer include: the EUVE Archive mailserver; the CEA ftp site; the EUVE Guest Observer Mailserver; and the Astronomical Data System node. The EUVE Performance Assurance team is responsible for verifying that these public EUVE databases are working properly, and that the public availability of EUVE data contained therein does not infringe any data rights which may have been assigned. In this poster, we describe the Quality Assurance (QA) procedures we have developed from the approach of QA as a service organization, thus reflecting the overall EUVE philosophy of Quality Assurance integrated into normal operating procedures, rather than imposed as an external, post facto, control mechanism.

    NASA Astrophysics Data System (ADS)

    Fanslau, Melody; Young, Janelle

    The production of a quality and safe food product is essential to the success of any food manufacturing facility. Because of this great importance, a career in quality can be extremely rewarding. Without happy customers willing to buy a product, a company would not be able to survive. Quality issues such as foreign objects, spoiled or mislabeled product, failure to meet net weight requirements, or a recall can all turn customers away from buying a product. The food industry is a customer-driven market in which some consumers are brand loyal based on a history of high quality or in which a single bad experience with a product will turn them away for a lifetime. With this said, the main role of a quality department is to help ensure that quality issues such as these are eliminated or kept to a minimum to maintain or increase the number of customers purchasing their product.

  10. Quality Control of Meteorological Observations

    NASA Technical Reports Server (NTRS)

    Collins, William; Dee, Dick; Rukhovets, Leonid

    1999-01-01

    For the first time, a problem of the meteorological observation quality control (QC) was formulated by L.S. Gandin at the Main Geophysical Observatory in the 70's. Later in 1988 L.S. Gandin began adapting his ideas in complex quality control (CQC) to the operational environment at the National Centers for Environmental Prediction. The CQC was first applied by L.S.Gandin and his colleagues to detection and correction of errors in rawinsonde heights and temperatures using a complex of hydrostatic residuals.Later, a full complex of residuals, vertical and horizontal optimal interpolations and baseline checks were added for the checking and correction of a wide range of meteorological variables. some other of Gandin's ideas were applied and substantially developed at other meteorological centers. A new statistical QC was recently implemented in the Goddard Data Assimilation System. The central component of any quality control is a buddy check which is a test of individual suspect observations against available nearby non-suspect observations. A novel feature of this test is that the error variances which are used for QC decision are re-estimated on-line. As a result, the allowed tolerances for suspect observations can depend on local atmospheric conditions. The system is then better able to accept extreme values observed in deep cyclones, jet streams and so on. The basic statements of this adaptive buddy check are described. Some results of the on-line QC including moisture QC are presented.

    There is a wide variation in laboratory practice with regard to implementation and review of internal quality control (IQC). A poor approach can lead to a spectrum of scenarios from validation of incorrect patient results to over investigation of falsely rejected analytical runs. This article will provide a practical approach for the routine clinical biochemistry laboratory to introduce an efficient quality control system that will optimise error detection and reduce the rate of false rejection. Each stage of the IQC system is considered, from selection of IQC material to selection of IQC rules, and finally the appropriate action to follow when a rejection signal has been obtained. The main objective of IQC is to ensure day-to-day consistency of an analytical process and thus help to determine whether patient results are reliable enough to be released. The required quality and assay performance varies between analytes as does the definition of a clinically significant error. Unfortunately many laboratories currently decide what is clinically significant at the troubleshooting stage. Assay-specific IQC systems will reduce the number of inappropriate sample-run rejections compared with the blanket use of one IQC rule. In practice, only three or four different IQC rules are required for the whole of the routine biochemistry repertoire as assays are assigned into groups based on performance. The tools to categorise performance and assign IQC rules based on that performance are presented. Although significant investment of time and education is required prior to implementation, laboratories have shown that such systems achieve considerable reductions in cost and labour.

  13. Quality assurance and quality control in monitoring programs

    Shampine, W.J.

    1993-01-01

    There are three general characteristics of the data to be collected in a monitoring program that should be met in order to maximize the use and value of the data: the data quality should be known the data type and quality should be consistent and comparable, and the data should be available and accessible. Potential problems with each of these characteristics are addressed effectively by quality assurance and quality control. One of the most important aspects of quality assurance in a monitoring program is the development of a quality assurance plan, which should identify clearly the quality of the data needed and describe in detail the planned actions to provide confidence that the program will meet its stated objectives. Quality control data, which allow for the quality and suitability of the environmental data to be evaluated and ascertained, should be collected and utilized as an integral part of the QA effort associated with a monitoring program.

  14. Quality Control by Artificial Vision

    2010-01-01

    Computational technology has fundamentally changed many aspects of our lives. One clear evidence is the development of artificial-vision systems, which have effectively automated many manual tasks ranging from quality inspection to quantitative assessment. In many cases, these machine-vision systems are even preferred over manual ones due to their repeatability and high precision. Such advantages come from significant research efforts in advancing sensor technology, illumination, computational hardware, and image-processing algorithms. Similar to the Special Section on Quality Control by Artificial Vision published two years ago in Volume 17, Issue 3 of the Journal of Electronic Imaging, the present one invited papers relevant to fundamental technology improvements to foster quality control by artificial vision, and fine-tuned the technology for specific applications. We aim to balance both theoretical and applied work pertinent to this special section theme. Consequently, we have seven high-quality papers resulting from the stringent peer-reviewing process in place at the Journal of Electronic Imaging. Some of the papers contain extended treatment of the authors work presented at the SPIE Image Processing: Machine Vision Applications conference and the International Conference on Quality Control by Artificial Vision. On the broad application side, Liu et al. propose an unsupervised texture image segmentation scheme. Using a multilayer data condensation spectral clustering algorithm together with wavelet transform, they demonstrate the effectiveness of their approach on both texture and synthetic aperture radar images. A problem related to image segmentation is image extraction. For this, O'Leary et al. investigate the theory of polynomial moments and show how these moments can be compared to classical filters. They also show how to use the discrete polynomial-basis functions for the extraction of 3-D embossed digits, demonstrating superiority over Fourier

    Fraud investigation and fraud control are entirely different processes. Similarly the auditing of a life insurance company and the issuing of life insurance policies and business quality control are not the same. Business quality control and fraud control have much in common. In this article, these similarities are explored and a case is made that companies issuing life insurance policies should consider the business quality control approach rather than the more traditional investigatory methods.

  16. Adequate Wound Care and Use of Bed Nets as Protective Factors against Buruli Ulcer: Results from a Case Control Study in Cameroon

    Background Buruli ulcer is an infectious disease involving the skin, caused by Mycobacterium ulcerans. Its exact transmission mechanism remains unknown. Several arguments indicate a possible role for insects in its transmission. A previous case-control study in the Nyong valley region in central Cameroon showed an unexpected association between bed net use and protection against Buruli ulcer. We investigated whether this association persisted in a newly discovered endemic Buruli ulcer focus in Bankim, northwestern Cameroon. Methodology/Principal Findings We conducted a case-control study on 77 Buruli ulcer cases and 153 age-, gender- and village-matched controls. Participants were interviewed about their activities and habits. Multivariate conditional logistic regression analysis identified systematic use of a bed net (Odds-Ratio (OR) = 0.4, 95% Confidence Interval [95%CI] = [0.2–0.9], p-value (p) = 0.04), cleansing wounds with soap (OR [95%CI] = 0.1 [0.03–0.3], p<0.0001) and growing cassava (OR [95%CI] = 0.3 [0.2–0.7], p = 0.005) as independent protective factors. Independent risk factors were bathing in the Mbam River (OR [95%CI] = 6.9 [1.4–35], p = 0.02) and reporting scratch lesions after insect bites (OR [95%CI] = 2.7 [1.4–5.4], p = 0.004). The proportion of cases that could be prevented by systematic bed net use was 32%, and by adequate wound care was 34%. Conclusions/Significance Our study confirms that two previously identified factors, adequate wound care and bed net use, significantly decreased the risk of Buruli ulcer. These associations withstand generalization to different geographic, climatic and epidemiologic settings. Involvement of insects in the household environment, and the relationship between wound hygiene and M. ulcerans infection should now be investigated. PMID:22087346

  17. Towards Quality Assurance and an Adequate Risk Management in Geotechnical Engineering - Application of Eurocode 7 and DIN 4020 in Engineering Geology

    NASA Astrophysics Data System (ADS)

    Schetelig, Kurt; Heitfeld, Michael; von Soos, Paul; Stocker, Manfred; Mainz, Mark

    A key issue of engineering geology is the extreme variety of soil and rock, their heterogeneity and at places anisotropy, the fabric of rockmasses, the influence of water, the primary stresses and their change into a secondary stress field by loading or unloading. Changeable properties of some kinds of soil and rock, the effect of different scales of laboratory tests, field tests and the size of the structure create further questions. Considering the difficulties of investigation of the underground, size and complexity of the structure and its construction procedure Eurocode 7 and DIN 4020 have introduced geotechnical categories. The design concept in geotechnical category 3 is mostly combined with the observational method. This requires the establishment of an adequate monitoring system and a permanent comparison of the design assumptions (pre-calculated displacements or stresses) with the recorded values. The goals and handling of Eurocode 7 and DIN 4020 are demonstrated by means of site examples.

  1. Designing in quality through design control: a manufacturer's perspective.

    PubMed

    Lasky, F D; Boser, R B

    1997-05-01

    Quality by design is a comprehensive program that begins with understanding user needs and continues through (but does not end with) monitoring customer acceptance. Management tools and processes such as ISO 9000 standards and the Food and Drug Administration Quality System Regulations exist to guide medical device manufacturers in quality practices. The goal is to deliver products acceptable for their intended use. Quality control begins with defining attributes ranging from color to accuracy and precision. Failure mode and effects analysis and risk analysis consider both probability and severity of potential malfunctions and their effects on patients or operators. Tools used to implement design and production practices include Program Evaluation and Review Technique (PERT) charts and industry-conceived concepts, such as Six Sigma techniques. Their use varies with manufacturer, depending on product and customer needs and the manufacturer's specific quality practices. Verification confirms that input goals are met. Then, validation assures that intended clinical needs are continually satisfied by establishing adequate production specifications. Conformance is monitored to verify that stable, consistent processes are in place, and precise user instructions enable the device to satisfy its intended use. Finally, complaint tracking can help assess whether needs have been met. Modifications in service, hardware, or instructions (including quality control) might be required. Therefore, both manufacturers and users work in partnership for continual improvement. The manufacturer's knowledge of design, production, and service needs of its devices enable it to recommend appropriate quality-control protocols for clinical testing.

  2. Quality control of radiant heaters

    2005-09-01

    Based on infrared thermography, a non-destructive testing and evaluation (NDT&E) procedure is proposed for defects assessment on radiant heaters. Under a short electrical excitation, an infrared camera captures the cooling process of the heaters. Breaking the thermographic images down not only makes easiest the location of defects but it also allows their classification. Several kinds of defects have been taken into account: lack of supporting brackets; defects originated by a deficiency in the heating material; those from an excess of heating material; and those parts of the heating elements which are in wrong contact (non-contact or semi-buried) with the substrate. Each kind of analyzed defect has a different thermal history after the electrical excitation because of its nature. By means of computer vision techniques, the defects can be spatially located. The "chain code" was employed to follow the pattern of the heating element and so concentrate the analysis in points belonging to the pattern. A good agreement with analysis made under human's criteria is achieved. However, using infrared cameras and processing the data with computer vision algorithms allows controlling in-site the quality of the product without any subjectivity. So, the heaters manufacturing industry could come along with the implementation of this automatic detection procedure. Experimental results that validate the proposed method will be presented and discussed in this paper.

  3. Quality Control in Small Groups

    NASA Astrophysics Data System (ADS)

    Lemmens, L. F.

    2008-11-01

    The smallness of some groups in a set up to control the quality of a service using questionnaires limits the size of the samples, this limitation has several consequences. Indeed the common approach used for relatively large groups, based on the central limit theorem and the law of large numbers, cannot be used anymore to construct estimators for the parameters of the model. Using an inverse probability will lift these restrictions. A questionnaire is a collection of items. In an item the respondent indicates on a Likert scale his or her agreement with a statement. Dimensions are a set of items dealing with one aspect of the service. In a questionnaire several dimensions are addressed but usually the items are presented in a random sequence. The model for an item is hierarchical with following components: a multivariate hypergeometric model takes the sampling in a finite population into account, the multinomial serves as a prior for the sampling and the Dirichlet-distribution serves as a prior for the multinomials. The composition of dimensions allows to use the posterior for one of the items as a prior for another item of that dimension and so on. After analysis of several questionnaires using this model, the reliability of the responses from some respondents turned out to be a key-problem, in the sense the responses can be classified into at least two classes and a decision rule had to be developed to neglect some of them. The influence of rejecting some answers, on the confidence for the most plausible statement can be estimated. This leads often to the result that there is only minimal evidence for the most probable statement.

    The problems associated with blending of the AMK additive with Jet A, and the base fuel effects on AMK properties are addressed. The results from the evaluation of some of the quality control techniques for AMK are presented. The principal conclusions of this investigation are: significant compositional differences for base fuel (Jet A) within the ASTM specification DI655; higher aromatic content of the base fuel was found to be beneficial for the polymer dissolution at ambient (20 C) temperature; using static mixer technology, the antimisting additive (FM-9) is in-line blended with Jet A, producing AMK which has adequate fire-protection properties 15 to 20 minutes after blending; degradability of freshly blended and equilibrated AMK indicated that maximum degradability is reached after adequate fire protection is obtained; the results of AMK degradability as measured by filter ratio, confirmed previous RAE data that power requirements to decade freshly blended AMK are significantly higher than equilibrated AMK; blending of the additive by using FM-9 concentrate in Jet A produces equilibrated AMK almost instantly; nephelometry offers a simple continuous monitoring capability and is used as a real time quality control device for AMK; and trajectory (jet thurst) and pressure drop tests are useful laboratory techniques for evaluating AMK quality.

    1966-01-01

    This paper describes the Quality Control Program at Daytona Beach Junior College, including course descriptions. The program in quality control required communication between the college and the American Society for Quality Control (ASQC). The college has machinery established for certification of the learning process, and the society has the source of teachers who are competent in the technical field and who are the employers of the educational products. The associate degree for quality control does not have a fixed program, which can serve all needs, any more than all engineering degrees have identical programs. The main ideas which would be common to all quality control programs are the concept of economic control of a repetitive process and the concept of developing individual potentialities into individuals who are needed and productive.

    2006-01-01

    Background State-wide surveys of recent mothers conducted over the past decade in Victoria, one state of Australia, have identified that women are consistently less satisfied with the care they received in hospital following birth compared with other aspects of maternity care. Little is known of caregivers' perspectives on the provision ofhospital postnatal care: how care is organised and provided in different hospitals; what constrains the provision of postnatal care (apart from funding) and what initiatives are being undertaken to improve service delivery. A state-widereview of organisational structures and processes in relation to the provision of hospital postnatal care in Victoria was undertaken. This paper focuses on the impact of staffing issues on the provision of quality postnatal care from the perspective of care providers. Methods A study of care providers from Victorian public hospitals that provide maternity services was undertaken. Datawere collected in two stages. Stage one: a structured questionnaire was sent to all public hospitals in Victoria that provided postnatal care (n = 73), exploring the structure and organisation of care (e.g. staffing, routine observations, policy framework and discharge planning). Stage two: 14 maternity units were selected and invited to participate in a more in-depth exploration of postnatal care. Thirty-eight key informant interviews were undertaken with midwives (including unit managers, associate unit managers and clinical midwives) and a medical practitioner from eachselected hospital. Results Staffing was highlighted as a major factor impacting on the provision of quality postnatal care. There were significant issues associated with inadequate staff/patient ratios; staffing mix; patient mix; prioritisation of birth suites over postnatal units; and the use of non-permanent staff. Forty-three percent of hospitals reported having only midwives (i.e. no non-midwives) providing postnatal care. Staffing issues impact on

Among the items discussed are flying qualities criteria development, the role of simulation, and communication between flying qualities specialists and control system designers.

  11. Control by quality: proposition of a typology.

    PubMed

    Pujo, P; Pillet, M

    The application of Quality tools and methods in industrial management has always had a fundamental impact on the control of production. It influences the behavior of the actors concerned, while introducing the necessary notions and formalizations, especially for production systems with little or no automation, which constitute a large part of the industrial activity. Several quality approaches are applied in the workshop and are implemented at the level of the control. In this paper, the authors present a typology of the various approaches that have successively influenced control, such as statistical process control, quality assurance, and continuous improvement. First the authors present a parallel between production control and quality organizational structure. They note the duality between control, which is aimed at increasing productivity, and quality, which aims to satisfy the needs of the customer. They also note the hierarchical organizational structure of these two systems of management with, at each level, the notion of a feedback loop. This notion is fundamental to any kind of decision making. The paper is organized around the operational, tactical, and strategic levels, by describing for each level the main methods and tools for control by quality. The overview of these tools and methods starts at the operational level, with the Statistical Process Control, the Taguchi technique, and the "six sigma" approach. On the tactical level, we find a quality system approach, with a documented description of the procedures introduced in the firm. The management system can refer here to Quality Assurance, Total Productive Maintenance, or Management by Total Quality. The formalization through procedures of the rules of decision governing the process control enhances the validity of these rules. This leads to the enhancement of their reliability and to their consolidation. All this counterbalances the human, intrinsically fluctuating, behavior of the control

    2015-01-01

    Cardiac aging is an intrinsic process that results in impaired cardiac function, along with cellular and molecular changes. These degenerative changes are intimately associated with quality control mechanisms. This review provides a general overview of the clinical and cellular changes which manifest in cardiac aging, and the quality control mechanisms involved in maintaining homeostasis and retarding aging. These mechanisms include autophagy, ubiquitin-mediated turnover, apoptosis, mitochondrial quality control and cardiac matrix homeostasis. Finally, we discuss aging interventions that have been observed to impact cardiac health outcomes. These include caloric restriction, rapamycin, resveratrol, GDF11, mitochondrial antioxidants and cardiolipin-targeted therapeutics. A greater understanding of the quality control mechanisms that promote cardiac homeostasis will help to understand the benefits of these interventions, and hopefully lead to further improved therapeutic modalities.

A comprehensive protocol was implemented at four Clinical Centers (CC) for the generation of data on sedentary subjects. This group included 450 caucasians from 90 nuclear families (father, mother, three children) and 200 black subjects from 40 to 100 family units over a 5-year period. The entire family was tested before and after a 20-week exercise training program. The fifth participating center, the Data Coordinating Center (DCC), is responsible for data management and data analysis. A Consortium Coordinating Center (CCC) responsible for the overall coordination and direction of the study was established at the Quebec CC. Quality assurance and quality control are jointly coordinated by the CCC and the DCC. A multicenter study of this magnitude requires careful standardization of all procedures and constant monitoring of quality control at all levels of operation. This report describes the quality assurance and quality control measures implemented in the HERITAGE Family Study, including some examples with real data.

    The goal of any clinical laboratory should be to provide patients with the most accurate test results possible. This is accomplished through various overlapping programs that continuously monitor and optimize all aspects of a test, including decisions by the laboratory to offer a test, the decision of providers to request the test, the testing itself, and the reporting of results to the referral source and patient. The levels at which test performance and accuracy can be optimized are encompassed under quality control (QC) and quality assurance (QA). The monitoring of QC and QA problems allows for the integration of these parameters into a total quality management program. This unit reviews QC and QA guidelines, in addition to discussing how to establish a quality assurance program.

    The preparation and attractive performance of nanomaterials for innovative detection schemes of food related compounds are described. Nickel nanowires growths by the template procedure were used for magnetoswitchable control of electrochemical processes of sugar-like compounds at the electrode surface. Gold nanoparticles were also prepared by reducing a gold solution with different phenolic compounds. The different antioxidant power of these compounds allow to modulate the kinetic growth of gold nanoparticles. Finally, an index of the antioxidant power based on the growth of gold nanoparticle is reported.

    This study investigates the feasibility of remote quality control using a host of advanced automation equipment with Internet accessibility. Recent emphasis on product quality and reduction of waste stems from the dynamic, globalized and customer-driven market, which brings opportunities and threats to companies, depending on the response speed and production strategies. The current trends in industry also include a wide spread of distributed manufacturing systems, where design, production, and management facilities are geographically dispersed. This situation mandates not only the accessibility to remotely located production equipment for monitoring and control, but efficient means of responding to changing environment to counter process variations and diverse customer demands. To compete under such an environment, companies are striving to achieve 100%, sensor-based, automated inspection for zero-defect manufacturing. In this study, the Internet-based quality control scheme is referred to as "E-Quality for Manufacturing" or "EQM" for short. By its definition, EQM refers to a holistic approach to design and to embed efficient quality control functions in the context of network integrated manufacturing systems. Such system let designers located far away from the production facility to monitor, control and adjust the quality inspection processes as production design evolves.

    1990-12-01

    The Asbestos NESHAP requires facility owners and/or operators involved in demolition and renovation activities to control emissions of particulate asbestos to the outside air because no safe concentration of airborne asbestos has ever been established. The primary method used to control asbestos emissions is to adequately wet the Asbestos Containing Material (ACM) with a wetting agent prior to, during and after demolition/renovation activities. The purpose of the document is to provide guidance to asbestos inspectors and the regulated community on how to determine if friable ACM is adequately wet as required by the Asbestos NESHAP.

    Next-generation sequencing (NSG) is an important method for gathering large amounts of sequencing data for different types of applications regarding the diagnosis and response to treatment of different diseases. An important step in the NGS process is the quality control of sequencing libraries, which can influence the yield and efficiency of the sequencing run. This study evaluated two different methods for library quality control, Agilent Bioanalyzer and qPCR, and showed that both methods can be used. However, as is the case with any analytical method, they have their limitations. The Agilent Bioanalyzer quantifies only the high quality libraries, but it underestimates their concentration, while qPCR also quantifies lower quality libraries, but it overestimates their concentration.

    The Copernicus Space Component Data Access system (CSCDA) incorporates data contributions from a wide range of satellite missions. Through EO data handling and distribution, CSCDA serves a set of Copernicus Services related to Land, Marine and Atmosphere Monitoring, Emergency Management and Security and Climate Change. The quality of the delivered EO products is the responsibility of each contributing mission, and the Copernicus data Quality Control (CQC) service supports and complements such data quality control activities. The mission of the CQC is to provide a service of quality assessment on the provided imagery, to support the investigation related to product quality anomalies, and to guarantee harmonisation and traceability of the quality information. In terms of product quality control, the CQC carries out analysis of representative sample products for each contributing mission as well as coordinating data quality investigation related to issues found or raised by Copernicus users. Results from the product analysis are systematically collected and the derived quality reports stored in a searchable database. The CQC service can be seen as a privileged focal point with unique comparison capacities over the data providers. The comparison among products from different missions suggests the need for a strong, common effort of harmonisation. Technical terms, definitions, metadata, file formats, processing levels, algorithms, cal/val procedures etc. are far from being homogeneous, and this may generate inconsistencies and confusion among users of EO data. The CSCDA CQC team plays a significant role in promoting harmonisation initiatives across the numerous contributing missions, so that a common effort can achieve optimal complementarity and compatibility among the EO data from multiple data providers. This effort is done in coordination with important initiatives already working towards these goals (e.g. INSPIRE directive, CEOS initiatives, OGC standards, QA4EO

    As a rule, only proteins that have reached a native, folded and assembled structure are transported to their target organelles and compartments within the cell. In the secretory pathway of eukaryotic cells, this type of sorting is particularly important. A variety of molecular mechanisms are involved that distinguish between folded and unfolded proteins, modulate their intracellular transport, and induce degradation if they fail to fold. This phenomenon, called quality control, occurs at several levels and involves different types of folding sensors. The quality control system provides a stringent and versatile molecular sorting system that guaranties fidelity of protein expression in the secretory pathway. PMID:11260794

    High Pressure Liquid Chromatography (HPLC) as a quality control tool for polyimide resins and prepregs are presented. A data base to help establish accept/reject criteria for these materials was developed. This work is intended to supplement, not replace, standard quality control tests normally conducted on incoming resins and prepregs. To help achieve these objectives, the HPLC separation of LARC-160 polyimide precursor resin was characterized. Room temperature resin aging effects were studied. Graphite reinforced composites made from fresh and aged resin were fabricated and tested to determine if changes observed by HPLC were significant.

    To examine the quality and comparability of biopsy needles. 310 biopsy needles of 40 types were examined microscopically and their suitability for penetrating tissues were studied. For this purpose the pressure required to penetrate a phantom was evaluated. The results were correlated with the diameter, design and construction. 50 of the 310 needles (16%) showed faults on microscopic examination. Measurements of identical needle types within a single production run showed variations in penetration pressures up to 330% (measured as force required for penetration), the average variation was 88%. The results show that the quality of biopsy needles is not constant and leaves something to be desired. To what extent variations in quality affect the biopsy material cannot be estimated. Nevertheless, the present results indicate that stricter quality control of biopsy needles is desirable.

    1998-07-01

    Modern laboratories, be they in government or industry, operate under strict quality assurance and quality control (QA/QC) guidelines. Yet, these topics are rarely covered in undergraduate laboratories, or are presented as isolated experiments. This fosters the false idea that QA/QC is a separate subject when in actuality it is an integral part of analytical chemistry. It is possible to incorporate QA/QC into existing student laboratories by utilizing blanks, replicates, knowns and spiked samples. Proper use of QA/QC, coupled to an understanding of fundamental chemical principles and statistics strengthens traditional laboratory exercises. Concepts of accuracy and precision are transformed from abstractions into concrete data, and student skills in troubleshooting and problem solving are enhanced.

    The present study introduces the concept of statistical quality control in automotive wheel bearings manufacturing processes. Defects on products under analysis can have a direct influence on passengers' safety and comfort. At present, the use of vibration analysis on machine tools for quality control purposes is not very extensive in manufacturing facilities. Noise and vibration are common quality problems in bearings. These failure modes likely occur under certain operating conditions and do not require high vibration amplitudes but relate to certain vibration frequencies. The vibration frequencies are affected by the type of surface problems (chattering) of ball races that are generated through grinding processes. The purpose of this paper is to identify grinding process variables that affect the quality of bearings by using statistical principles in the field of machine tools. In addition, an evaluation of the quality results of the finished parts under different combinations of process variables is assessed. This paper intends to establish the foundations to predict the quality of the products through the analysis of self-induced vibrations during the contact between the grinding wheel and the parts. To achieve this goal, the overall self-induced vibration readings under different combinations of process variables are analysed using statistical tools. The analysis of data and design of experiments follows a classical approach, considering all potential interactions between variables. The analysis of data is conducted through analysis of variance (ANOVA) for data sets that meet normality and homoscedasticity criteria. This paper utilizes different statistical tools to support the conclusions such as chi squared, Shapiro-Wilks, symmetry, Kurtosis, Cochran, Hartlett, and Hartley and Krushal-Wallis. The analysis presented is the starting point to extend the use of predictive techniques (vibration analysis) for quality control. This paper demonstrates the existence

  6. Quality and Control of Water Vapor Winds

    NASA Technical Reports Server (NTRS)

    Jedlovec, Gary J.; Atkinson, Robert J.

    1996-01-01

    Water vapor imagery from the geostationary satellites such as GOES, Meteosat, and GMS provides synoptic views of dynamical events on a continual basis. Because the imagery represents a non-linear combination of mid- and upper-tropospheric thermodynamic parameters (three-dimensional variations in temperature and humidity), video loops of these image products provide enlightening views of regional flow fields, the movement of tropical and extratropical storm systems, the transfer of moisture between hemispheres and from the tropics to the mid- latitudes, and the dominance of high pressure systems over particular regions of the Earth. Despite the obvious larger scale features, the water vapor imagery contains significant image variability down to the single 8 km GOES pixel. These features can be quantitatively identified and tracked from one time to the next using various image processing techniques. Merrill et al. (1991), Hayden and Schmidt (1992), and Laurent (1993) have documented the operational procedures and capabilities of NOAA and ESOC to produce cloud and water vapor winds. These techniques employ standard correlation and template matching approaches to wind tracking and use qualitative and quantitative procedures to eliminate bad wind vectors from the wind data set. Techniques have also been developed to improve the quality of the operational winds though robust editing procedures (Hayden and Veldon 1991). These quality and control approaches have limitations, are often subjective, and constrain wind variability to be consistent with model derived wind fields. This paper describes research focused on the refinement of objective quality and control parameters for water vapor wind vector data sets. New quality and control measures are developed and employed to provide a more robust wind data set for climate analysis, data assimilation studies, as well as operational weather forecasting. The parameters are applicable to cloud-tracked winds as well with minor

    OBJECTIVE To evaluate the efficacy and safety of canagliflozin, a sodium glucose cotransporter 2 inhibitor, compared with sitagliptin in subjects with type 2 diabetes inadequately controlled with metformin plus sulfonylurea. RESEARCH DESIGN AND METHODS In this 52-week, randomized, double-blind, active-controlled, phase 3 study, subjects using stable metformin plus sulfonylurea (N = 755) received canagliflozin 300 mg or sitagliptin 100 mg daily. Primary end point was change from baseline in A1C at 52 weeks. Secondary end points included change in fasting plasma glucose (FPG) and systolic blood pressure (BP), and percent change in body weight, triglycerides, and HDL cholesterol. Safety was assessed based on adverse event (AE) reports. RESULTS At 52 weeks, canagliflozin 300 mg demonstrated noninferiority and, in a subsequent assessment, showed superiority to sitagliptin 100 mg in reducing A1C (−1.03% [−11.3 mmol/mol] and −0.66% [−7.2 mmol/mol], respectively; least squares mean difference between groups, −0.37% [95% CI, −0.50 to −0.25] or −4.0 mmol/mol [−5.5 to −2.7]). Greater reductions in FPG, body weight, and systolic BP were observed with canagliflozin versus sitagliptin (P < 0.001). Overall AE rates were similar with canagliflozin (76.7%) and sitagliptin (77.5%); incidence of serious AEs and AE-related discontinuations was low for both groups. Higher incidences of genital mycotic infections and osmotic diuresis–related AEs were observed with canagliflozin, which led to one discontinuation. Hypoglycemia rates were similar in both groups. CONCLUSIONS Findings suggest that canagliflozin may be a new therapeutic tool providing better improvement in glycemic control and body weight reduction than sitagliptin, but with increased genital infections in subjects with type 2 diabetes using metformin plus sulfonylurea.

  13. Nutritional adequacy and quality control of rodent diets.

    PubMed

    Newberne, P M; Fox, J G

    1980-04-01

    One of the most often neglected variables in experimental investigations using rodents is the diet. Recent observations that diets can influence the response of a rodent to the drug, chemical or other factors under study, with biased interpretation of results, have drawn great interest. In order to be assured that the biologic response observed is a reflection of the material or condition under study, it is imperative that the diet provide essential nutrients in the proper proportions and that contaminants be kept to a minimum. Quality control is the key to these requirements; rodent diets can provide adequate nutrition, free of significant contamination. The diets which can be provided vary according to the degree of refinements; the three major types are (1) natural product, (2) semipurified and (3) chemically defined diets. Natural product diets may be open or closed formula, depending on the amount of information that the label reveals. Guaranteed analyses of proximate nutrients are provided but are of little use in assessing the nutrient value of the formulation. The National Academy of Sciences, National Research Council publications on laboratory animal nutrient requirements should be available to all investigators using experimental animals to help them evaluate the nutritional adequacy of the diets they use. Rats and mice may be considered together under some circumstances relative to crude dietary needs, but the Syrian golden hamster should be treated separately for purposes of diet. This species appears to digest foods more like a ruminant. An ideal diet for rodents is not on the horizon because of variable needs relative to different types of research and holding. Storage and shelf life of rodent diets also play important roles in providing adequate nutrition. Variations in moisture, temperature and exposure to other chemicals can affect the quality of the feed and research results. In addition, a number of chemical and biological contaminants have been

  16. Systematic Quality Control Analysis of LINCS Data

    PubMed Central

    2016-01-01

    The Library of Integrated Cellular Signatures (LINCS) project provides comprehensive transcriptome profiling of human cell lines before and after chemical and genetic perturbations. Its L1000 platform utilizes 978 landmark genes to infer the transcript levels of 14,292 genes computationally. Here we conducted the L1000 data quality control analysis by using MCF7, PC3, and A375 cell lines as representative examples. Before perturbations, a promising 80% correlation in transcriptome was observed between L1000‐ and Affymetrix HU133A‐platforms. After library‐based shRNA perturbations, a moderate 30% of differentially expressed genes overlapped between any two selected controls viral vectors using the L1000 platform. The mitogen‐activated protein kinase, vascular endothelial growth factor, and T‐cell receptor pathways were identified as the most significantly shared pathways between chemical and genetic perturbations in cancer cells. In conclusion, L1000 platform is reliable in assessing transcriptome before perturbation. Its response to perturbagens needs to be interpreted with caution. A quality control analysis pipeline of L1000 is recommended before addressing biological questions. PMID:27796074

    This paper is part of a study of intelligent architectures for distributed control and communications systems. The study focuses on optimizing control systems by evaluating the performance of middleware through quality of service (QoS) parameters and the optimization of control using Quality of Control (QoC) parameters. The main aim of this work is to study, design, develop, and evaluate a distributed control architecture based on the Data-Distribution Service for Real-Time Systems (DDS) communication standard as proposed by the Object Management Group (OMG). As a result of the study, an architecture called Frame-Sensor-Adapter to Control (FSACtrl) has been developed. FSACtrl provides a model to implement an intelligent distributed Event-Based Control (EBC) system with support to measure QoS and QoC parameters. The novelty consists of using, simultaneously, the measured QoS and QoC parameters to make decisions about the control action with a new method called Event Based Quality Integral Cycle. To validate the architecture, the first five Braitenberg vehicles have been implemented using the FSACtrl architecture. The experimental outcomes, demonstrate the convenience of using jointly QoS and QoC parameters in distributed control systems. PMID:25723145

  19. Protein quality control in the bacterial periplasm

    Miot, Marika; Betton, Jean-Michel

    2004-01-01

    The proper functioning of extracytoplasmic proteins requires their export to, and productive folding in, the correct cellular compartment. All proteins in Escherichia coli are initially synthesized in the cytoplasm, then follow a pathway that depends upon their ultimate cellular destination. Many proteins destined for the periplasm are synthesized as precursors carrying an N-terminal signal sequence that directs them to the general secretion machinery at the inner membrane. After translocation and signal sequence cleavage, the newly exported mature proteins are folded and assembled in the periplasm. Maintaining quality control over these processes depends on chaperones, folding catalysts, and proteases. This article summarizes the general principles which control protein folding in the bacterial periplasm by focusing on the periplasmic maltose-binding protein. PMID:15132751

    Tailor welded blanks were widely used in the automobile industry for their special advantages. A combination of different materials, thickness, and coatings could be welded together to form a blank for stamping car body panels. With the gradually growing consciousness on safety requirement of auto body structural, the business of laser tailor welded blanks is developing rapidly in China. Laser tailor welded blanks were just the semi products between steel factory and automobile manufacturers. As to the laser welding defects such as convexity and concavity, automobile industry had the strict requirement. In this paper, quality standard on laser tailor welded blanks were discussed. As for the production of laser tailor welded blanks, online quality control of laser tailor welded blanks was introduced. The image processing system for welding laser positioning and weld seam monitoring were used in the production of laser tailor welded blanks. The system analyzes images from the individual cameras and transmits the results to the machine control system via a CAN bus.

    Recent active research and new regulatory guidance on pharmaceutical cocrystals have increased the rate of their development as promising approaches to improve handling, storage stability, and bioavailability of poorly soluble active pharmaceutical ingredients (APIs). However, their complex structure and the limited amount of available information related to their performance may require development strategies that differ from those of single-component crystals to ensure their clinical safety and efficacy. This article highlights current methods of characterizing pharmaceutical cocrystals and approaches to controlling their quality. Different cocrystal regulatory approaches between regions are also discussed. The physical characterization of cocrystals should include elucidating the structure of their objective crystal form as well as their possible variations (e.g., polymorphs, hydrates). Some solids may also contain crystals of individual components. Multiple processes to prepare pharmaceutical cocrystals (e.g., crystallization from solutions, grinding) vary in their applicable ingredients, scalability, and characteristics of resulting solids. The choice of the manufacturing method affects the quality control of particular cocrystals and their formulations. In vitro evaluation of the properties that govern clinical performance is attracting increasing attention in the development of pharmaceutical cocrystals. Understanding and mitigating possible factors perturbing the dissolution and/or dissolved states, including solution-mediated phase transformation (SMPT) and precipitation from supersaturated solutions, are important to ensure the bioavailability of orally administrated lower-solubility APIs. The effect of polymer excipients on the performance of APIs emphasizes the relevance of formulation design for appropriate use.

    In this work we present the analysis of continuous waveform of the Algerian digital seismic network recorded during five years from 2008 to 2013 for twenty broadband stations using the power spectral densities (PSDs) and their corresponding probability density functions (PDFs) algorithm of McNamara, and Buland (2004). ADSN Broadband stations data quality is one main concern and interest of ADSN technical team. Indeed, the quality of the data from broadband stations is continuously controlled in quasi-realtime using "PQLX" (Pascal Quick Look eXtended) software to compute the PDFs and PSDs during the operation of the stations at different frequency range. At each station the level of noise is shown, which we can see diurnal and seasonal variation. From the data analysis, most of the ADSN Broadband stations display good records in the several frequency domains in relation with their site installation. However some of stations near the urban areas could present some noisy disturbances. This led sometimes to generate some ghost events. In the low frequency, some stations could be still influenced by the temperature variations. This long period of records from 2008 to 2013, led us to analyze and control the several stations year by year taking into account the seasons and to know about their work during five years. This analysis is also very important to improve in the future quality of station installation and choose the optimal station design in aim to reduce cultural noise and large fluctuation of temperature and pressure.

  10. Synthetic materials for platelet quality control.

    PubMed

    Lott, J A; Hartzell, R K; Longberry, J

    1983-01-01

    At present, the quality control of platelet counting by semi-automated and automated methods does not meet ideal standards. Controls prepared from human or animal platelets have limited stability, and some synthetic platelet controls that are available do not have the size distribution of fresh platelets. The platelet control materials described here are wholly synthetic; however, their particle size distribution is like that of normal human platelets, and the dispersing medium has the viscosity and surface tension of plasma. Two types of products are described. The first type are dilutions of the synthetic platelets which are handled like 3000-fold dilutions of platelet-rich plasma and are intended for direct use on instruments like the Coulter ZBI. The two dilution levels gave counts of about 50,000 and 200,000/microL on the Coulter ZBI and were found to be stable for at least 30 days at - 20C, 4C, and 37C, and at least eight months at 25C. The second type of product is handled like whole blood and is intended for direct use on instruments like the Coulter Model S-Plus. This product gave counts of about 200,000/microL and was found to be stable for at least 120 days at - 20C, 4C, 25C, and 37C. Freezing at - 20C produced some aggregates that dispersed after thawing and standing for several days prior to testing.

  4. Quality assurance and quality control of geochemical data—A primer for the research scientist

    USGS Publications Warehouse

    Geboy, Nicholas J.; Engle, Mark A.

    2011-01-01

    Geochemistry is a constantly expanding science. More and more, scientists are employing geochemical tools to help answer questions about the Earth and earth system processes. Scientists may assume that the responsibility of examining and assessing the quality of the geochemical data they generate is not theirs but rather that of the analytical laboratories to which their samples have been submitted. This assumption may be partially based on knowledge about internal and external quality assurance and quality control (QA/QC) programs in which analytical laboratories typically participate. Or there may be a perceived lack of time or resources to adequately examine data quality. Regardless of the reason, the lack of QA/QC protocols can lead to the generation and publication of erroneous data. Because the interpretations drawn from the data are primary products to U.S. Geological Survey (USGS) stakeholders, the consequences of publishing erroneous results can be significant. The principal investigator of a scientific study ultimately is responsible for the quality and interpretation of the project's findings, and thus must also play a role in the understanding, implementation, and presentation of QA/QC information about the data. Although occasionally ignored, QA/QC protocols apply not only to procedures in the laboratory but also in the initial planning of a research study and throughout the life of the project. Many of the tenets of developing a sound QA/QC program or protocols also parallel the core concepts of developing a good study: What is the main objective of the study? Will the methods selected provide data of enough resolution to answer the hypothesis? How should samples be collected? Are there known or unknown artifacts or contamination sources in the sampling and analysis methods? Assessing data quality requires communication between the scientists responsible for designing the study and those collecting samples, analyzing samples, treating data, and

  5. Tools for quality control of fingerprint databases

    NASA Astrophysics Data System (ADS)

    Swann, B. Scott; Libert, John M.; Lepley, Margaret A.

    2010-04-01

    Integrity of fingerprint data is essential to biometric and forensic applications. Accordingly, the FBI's Criminal Justice Information Services (CJIS) Division has sponsored development of software tools to facilitate quality control functions relative to maintaining its fingerprint data assets inherent to the Integrated Automated Fingerprint Identification System (IAFIS) and Next Generation Identification (NGI). This paper provides an introduction of two such tools. The first FBI-sponsored tool was developed by the National Institute of Standards and Technology (NIST) and examines and detects the spectral signature of the ridge-flow structure characteristic of friction ridge skin. The Spectral Image Validation/Verification (SIVV) utility differentiates fingerprints from non-fingerprints, including blank frames or segmentation failures erroneously included in data; provides a "first look" at image quality; and can identify anomalies in sample rates of scanned images. The SIVV utility might detect errors in individual 10-print fingerprints inaccurately segmented from the flat, multi-finger image acquired by one of the automated collection systems increasing in availability and usage. In such cases, the lost fingerprint can be recovered by re-segmentation from the now compressed multi-finger image record. The second FBI-sponsored tool, CropCoeff was developed by MITRE and thoroughly tested via NIST. CropCoeff enables cropping of the replacement single print directly from the compressed data file, thus avoiding decompression and recompression of images that might degrade fingerprint features necessary for matching.

  6. [Quality Control in Umbilical Cord Blood Bank

    PubMed

    Zhou, Sheng-Li; Song, Dao-Gang; Shen, Bai-Jun; Pan, Jie

    2001-03-01

    Recent clinical reports have demonstrated that the use of umbilical cord blood (UCB) opened a new source of stem cell for hematopoietic stem cell transplantation, leading to the development of cord blood banks world-wide. Prior to the large scale construction of UCB banks, quality control must be performed for health care providers and manufactures. With increasingly stringent regulatory requirement in blood industry, quality control is playing an important role in the operation of blood centers and stem cell laboratories. Reviewed the lectures in the biology of UCB and UCB banks published in recent years, our experiences were discussed in setting up Shandong blood bank to define process variables associated with the collection of UCB, to determine and optimize the procedures and materials used, to ascertain how UCB can be processed in clean room as mononucleated cell preparations, and to analyze using of long-term storage of UCB in research and clinic in the future. Our conclusions are: (1) the establishment of UCB banks for use in transplantation appears to be easy, effective and particularly suitable approach in China under cGMP conditions; (2) the procedures for volume reduction by closed and semi-automated blood processing system, SSP HLA typing, biocode and local computer net, microbiological tests and the 50 ml cryobags for storage constitute a cost efficient system for large-scale UCB banking; (3) the average of 60 ml UCB collection may contain sufficent marrow repopulating cells for children and most of adult recipients; and (4) hematopoietic stem and progenitor cells in cord blood have a more potent proliferative ability than those derived from bone marrow in cell expansion potentials.

  7. Granulostasis: Protein Quality Control of RNP Granules

    PubMed Central

    Alberti, Simon; Mateju, Daniel; Mediani, Laura; Carra, Serena

    2017-01-01

    Ribonucleoprotein (RNP) granules transport, store, or degrade messenger RNAs, thereby indirectly regulating protein synthesis. Normally, RNP granules are highly dynamic compartments. However, because of aging or severe environmental stress, RNP granules, in particular stress granules (SGs), convert into solid, aggregate-like inclusions. There is increasing evidence that such RNA-protein inclusions are associated with several age-related neurodegenerative diseases, such as amyotrophic lateral sclerosis (ALS), fronto-temporal dementia (FTD) and Alzheimer’s disease (AD). Thus, understanding what triggers the conversion of RNP granules into aggregates and identifying the cellular players that control RNP granules will be critical to develop treatments for these diseases. In this review article, we discuss recent insight into RNP and SG formation. More specifically, we examine the evidence for liquid-liquid phase separation (LLPS) as an organizing principle of RNP granules and the role of aggregation-prone RNA-binding proteins (RBPs) in this process. We further discuss recent findings that liquid-like SGs can sequester misfolded proteins, which promote an aberrant conversion of liquid SGs into solid aggregates. Importantly, very recent studies show that a specific protein quality control (PQC) process prevents the accumulation of misfolding-prone proteins in SGs and, by doing so, maintains the dynamic state of SGs. This quality control process has been referred to as granulostasis and it relies on the specific action of the HSPB8-BAG3-HSP70 complex. Additional players such as p97/valosin containing protein (VCP) and other molecular chaperones (e.g., HSPB1) participate, directly or indirectly, in granulostasis, and ensure the timely elimination of defective ribosomal products and other misfolded proteins from SGs. Finally, we discuss recent findings that, in the stress recovery phase, SGs are preferentially disassembled with the assistance of chaperones, and we discuss

    Kroll, Karl W; Mokaram, Nima E; Pelletier, Alexander R; Frankhouser, David E; Westphal, Maximillian S; Stump, Paige A; Stump, Cameron L; Bundschuh, Ralf; Blachly, James S; Yan, Pearlly

    2014-01-01

    QuaCRS (Quality Control for RNA-Seq) is an integrated, simplified quality control (QC) system for RNA-seq data that allows easy execution of several open-source QC tools, aggregation of their output, and the ability to quickly identify quality issues by performing meta-analyses on QC metrics across large numbers of samples in different studies. It comprises two main sections. First is the QC Pack wrapper, which executes three QC tools: FastQC, RNA-SeQC, and selected functions from RSeQC. Combining these three tools into one wrapper provides increased ease of use and provides a much more complete view of sample data quality than any individual tool. Second is the QC database, which displays the resulting metrics in a user-friendly web interface. It was designed to allow users with less computational experience to easily generate and view QC information for their data, to investigate individual samples and aggregate reports of sample groups, and to sort and search samples based on quality. The structure of the QuaCRS database is designed to enable expansion with additional tools and metrics in the future. The source code for not-for-profit use and a fully functional sample user interface with mock data are available at http://bioserv.mps.ohio-state.edu/QuaCRS/.

  9. A Total Quality-Control Plan with Right-Sized Statistical Quality-Control.

    PubMed

    Westgard, James O

    2017-03-01

    A new Clinical Laboratory Improvement Amendments option for risk-based quality-control (QC) plans became effective in January, 2016. Called an Individualized QC Plan, this option requires the laboratory to perform a risk assessment, develop a QC plan, and implement a QC program to monitor ongoing performance of the QC plan. Difficulties in performing a risk assessment may limit validity of an Individualized QC Plan. A better alternative is to develop a Total QC Plan including a right-sized statistical QC procedure to detect medically important errors. Westgard Sigma Rules provides a simple way to select the right control rules and the right number of control measurements.

    Ulceration of the foot in diabetes is common and disabling, and frequently leads to amputation of the leg. The pathogenesis of foot ulceration is complex, clinical presentation variable and management requires early expert assessment. Despite treatment, ulcers readily become chronic wounds. Chronic wounds are those that remain in a chronic inflammatory state failing a normal healing process patterns. This is partially caused by inefficient eradication of opportunistic pathogens like Pseudomonas aeruginosa. We propose its control or eradication will promote wound healing. Lactobacillus plantarum cultures supernatants (LAPS) shows antipathogenic and pro-healing properties. The main objective was to design two pharmaceutical dosage forms by using LAPS as active pharmaceutical ingredient and to perform its quality control, in vitro activity conservation tests and human trials (safety evaluation). Both selected formulations reach the technological quality expected for 120 days, shows adequate occlusive characteristics and proper adhesion to human skin. From the in vitro release assays were found that LAPS shows adequate release from matrix and maintain its antimicrobial and anti-biofilm activity. First human trials were developed and neither edema nor erythema on healthy skin voluntaries was found. We conclude that C80 and C100 are adequate for their use in future clinical trials to demonstrate a comprehensive therapeutic effectiveness in ischemic chronic wounds.

    Attaining high standards of efficiency and reliability in the practice of nuclear medicine requires appropriate quality control (QC) programs. For instance, the regular evaluation and comparison of extrinsic and intrinsic flood-field uniformity enables the quick correction of many gamma camera problems. Whereas QC tests for uniformity are usually performed by exposing the gamma camera crystal to a uniform flux of gamma radiation from a source of known activity, such protocols can vary significantly. Thus, there is a need for optimization and standardization, in part to allow direct comparison between gamma cameras from different vendors. In the present study, intrinsic uniformity was examined as a function of source distance, source activity, source volume and number of counts. The extrinsic uniformity and spatial resolution were also examined. Proper standard QC procedures need to be implemented because of the continual development of nuclear medicine imaging technology and the rapid expansion and increasing complexity of hybrid imaging system data. The present work seeks to promote a set of standard testing procedures to contribute to the delivery of safe and effective nuclear medicine services.

    2004-01-01

    Results of performance tests verifying the dosimetric properties of dosimetric systems are published in various reports (e.g. IAEA and EURADOS). However, there is hardly any information in the open literature relating to the uncertainty in a dose measurement or in the annual dose, which is increased by failure of the evaluation or data management system, damage of the dosemeter itself or by the loss of dosemeter. In this article, an attempt is made to estimate the importance of the above-mentioned conditions. This is achieved by sending questionnaires to about 200 approved dosimetric services in Europe. In total 88 questionnaires were returned and analysed. In the questionnaires, the frequency of occurrence of the various error conditions were investigated. Participants were also asked to evaluate the impact of the error condition from a dosimetric point of view and what countermeasures are taken. The article summarises all responses and compares different sources of errors according to their impact on the uncertainty of the resulting dose and gives a comprehensive overview on quality control actions and reliability on reported doses from European dosimetric services.

    The paper presents a procedure for measuring laser radiation reflection and scattering coefficients of polished surface. A relation between the scattered light intensity and the polished surface roughness is studied. It is demonstrated that colorimetric characteristics of non-metallic materials can be determined from the light scattering and reflection coefficients. This work has demonstrated a possibility of and created prerequisites for the development of an express method for tentative assessment of polished surface roughness. Of interest is the use of the β(Rz) function for the purposes of quality inspection of polished surfaces of natural and synthetic stone and other non-metallic materials. It was established that the most relevant parameter of roughness, which can be defined by the light reflection is Rz. The Dependency of the reflection factor from parameter of roughness Rz was approximated by formula with inaccuracy 5-10%. Inaccuracy of the determination of roughness Rz has formed 1%. It was shown that method of the surface roughness control using the light reflection factor is the most efficient for surfaces with roughness Rz <0.3 microns, typical for finish diamond-abrasive machining.

  1. The quality control theory of aging.

    PubMed

    Ladiges, Warren

    2014-01-01

    The quality control (QC) theory of aging is based on the concept that aging is the result of a reduction in QC of cellular systems designed to maintain lifelong homeostasis. Four QC systems associated with aging are 1) inadequate protein processing in a distressed endoplasmic reticulum (ER); 2) histone deacetylase (HDAC) processing of genomic histones and gene silencing; 3) suppressed AMPK nutrient sensing with inefficient energy utilization and excessive fat accumulation; and 4) beta-adrenergic receptor (BAR) signaling and environmental and emotional stress. Reprogramming these systems to maintain efficiency and prevent aging would be a rational strategy for increased lifespan and improved health. The QC theory can be tested with a pharmacological approach using three well-known and safe, FDA-approved drugs: 1) phenyl butyric acid, a chemical chaperone that enhances ER function and is also an HDAC inhibitor, 2) metformin, which activates AMPK and is used to treat type 2 diabetes, and 3) propranolol, a beta blocker which inhibits BAR signaling and is used to treat hypertension and anxiety. A critical aspect of the QC theory, then, is that aging is associated with multiple cellular systems that can be targeted with drug combinations more effectively than with single drugs. But more importantly, these drug combinations will effectively prevent, delay, or reverse chronic diseases of aging that impose such a tremendous health burden on our society.

  2. Timing control improves seabed survey data quality

    SciTech Connect

    Green, R.

    1996-04-01

    Seateam has completed development of and field-proven the Dolphin data acquisition and timing system for high-density surveys offshore. The Dolphin project was initiated to improve quality control of survey sensor data and ensure time synchronization, thus leading to faster turnaround of seabed terrain information. Data received from survey sensors is asynchronous, so the system must provide for data correlation. This includes establishment of data latency, i.e., the time difference between data creation and timing of the message at first-byte arrival at the recording system. Until recently, asynchronous data from multiple sensors was collected by a single computer, regardless of whether it had additional intelligent or non-intelligent serial cards. This computer was fully responsible for time stamping all incoming data, plus associated storage and distribution. Though this initially sufficed and is still applicable to low-density data, increasingly larger data volumes required an associated boost in the capability to time stamp data prior to eventual correction.

    2016-03-04

    Mass spectrometry-based proteomics coupled to liquid chromatography has matured into an automatized, high-throughput technology, producing data on the scale of multiple gigabytes per instrument per day. Consequently, an automated quality control (QC) and quality analysis (QA) capable of detecting measurement bias, verifying consistency, and avoiding propagation of error is paramount for instrument operators and scientists in charge of downstream analysis. We have developed an R-based QC pipeline called Proteomics Quality Control (PTXQC) for bottom-up LC-MS data generated by the MaxQuant software pipeline. PTXQC creates a QC report containing a comprehensive and powerful set of QC metrics, augmented with automated scoring functions. The automated scores are collated to create an overview heatmap at the beginning of the report, giving valuable guidance also to nonspecialists. Our software supports a wide range of experimental designs, including stable isotope labeling by amino acids in cell culture (SILAC), tandem mass tags (TMT), and label-free data. Furthermore, we introduce new metrics to score MaxQuant's Match-between-runs (MBR) functionality by which peptide identifications can be transferred across Raw files based on accurate retention time and m/z. Last but not least, PTXQC is easy to install and use and represents the first QC software capable of processing MaxQuant result tables. PTXQC is freely available at https://github.com/cbielow/PTXQC .

  18. Endoplasmic reticulum quality control and apoptosis.

    PubMed

    Groenendyk, Jody; Michalak, Marek

    2005-01-01

    The ER is one of the most important folding compartments within the cell, as well as an intracellular Ca(2+) storage organelle and it contains a number of Ca(2+) regulated molecular chaperones responsible for the proper folding of glycosylated as well as non-glycosylated proteins. The luminal environment of the ER contains Ca(2+) which is involved in regulating chaperones such as calnexin and calreticulin, as well as apoptotic proteins caspase-12 and Bap31, which may play an important role in determining cellular sensitivity to ER stress and apoptosis. The ER quality control system consists of several molecular chaperones, including calnexin, that assist in properly folding proteins and transporting them through the ER as well as sensing misfolded proteins, attempting to refold them and if this is not possible, targeting them for degradation. Accumulation of misfolded protein in the ER leads to activation of genes responsible for the expression of ER chaperones. The UPR mechanism involves transcriptional activation of chaperones by the membrane-localized transcription factor ATF6, in conjunction with the ER membrane kinase IRE1, as well as translational repression of protein synthesis by another ER membrane kinase PERK. When accumulation of misfolded protein becomes toxic, apoptosis is triggered, potentially with IRE1 involved in signaling via caspase-12. Both the extrinsic and intrinsic apoptotic pathways appear to culminate in the activation of caspases and this results in the recruitment of mitochondria in an essential amplifying manner. Bap31 may direct pro-apoptotic crosstalk between the ER and the mitochondria via Ca(2+) in conjunction with caspase-12 and calnexin. Accordingly, ER stress and the resultant Ca(2+) release must be very carefully regulated because of their effects in virtually all areas of cell function.

    1. OR staff members should familiarize themselves with basic air handling system terminology to better manage their own environment (eg, HVAC, air changes, air balancing, HEPA filtration). A working relationship with building engineers is an important skill for the OR nurse. 2. Knowledge of the standards on which air quality in the OR is based should assist in the process of planning for improved design--as well as in monitoring existing air quality. 3. Current standards balance energy savings with air changes and high levels of filtration to achieve optimum outcomes. Recommendations from design and engineering authorities (even for implant surgery) are based on average air changes and HEPA filtration, not laminar air flow. 4. The daily, operational role of the OR staff in maintaining high air quality includes managing traffic, using low-lint barrier materials, monitoring air quality indicators, and investigating unusual variances with the engineering staff for appropriate follow-up (eg, filter changes).

    NASA Astrophysics Data System (ADS)

    Versteeg, R. J.; Richardson, A.; Labrecque, D.

    2006-12-01

    The growing interest in processes, coupled with the reduction in cost and complexity of sensors which allow for continuous data collection and transmission is giving rise to vast amounts of semi autonomously collected data. Such data is typically collected from a range of physical and chemical sensors and transmitted - either at the time of collection, or periodically as a collection of measurements - to a central server. Such setups can collect vast amounts of data. In cases where power is not an issue one datapoint can be collected every minute, resulting in tens of thousands of data points per month per sensor. Especially in cases in which multiple sensors are deployed it is infeasible to examine each individual datapoint for each individual sensor, and users typically will look at aggregates of such data on a periodic (once a week to once every few months) basis. Such aggregates (and the timelag between data collection and data evaluation) will impact the ability to rapidly identify and resolve data issues. Thus, there is a need to integrate data qa/qc rules and procedures in the data collection process. These should be implemented such that data is analyzed for compliance the moment it arrives at the server, and that any issues with this data result in notification of cognizant personnel. Typical issues (encountered in the field) include complete system failure (resulting in no data arriving at all), to complete sensor failure (data is collected, but is meaningless), to partial sensor failure (sensor gives erratic readings, or starts to exhibit a bias) to partial powerloss (system collects and transmits data only intermittently). We have implemented a suite of such rules and tests as part of the INL developed performance monitoring system. These rules are invoked as part of a data qa/qc workflow, and result in quality indicators for each datapoint as well as user alerts in case of issues. Tests which are applied to the data include tests on individual

  11. Risk-Reliability Programming for Optimal Water Quality Control

    NASA Astrophysics Data System (ADS)

    Simonovic, Slobodan P.; Orlob, Gerald T.

    1984-06-01

    A risk-reliability programming approach is developed for optimal allocation of releases for control of water quality downstream of a multipurpose reservoir. Additionally, the approach allows the evaluation of optimal risk/reliability values. Risk is defined as a probability of not satisfying constraints given in probabilistic form, e.g., encroachment of water quality reservation on that for flood control. The objective function includes agricultural production losses that are functions of water quality, and risk-losses associated with encroachment of the water quality control functions on reservations for flood control, fisheries, and irrigation. The approach is demonstrated using data from New Melones Reservoir on the Stanislaus River in California. Results indicate that an optimum water quality reservation exists for a given set of quality targets and loss functions. Additional analysis is presented to determine the sensitivity of optimization results to agricultural production loss functions and the influence of statistically different river flows on the optimal reservoir storage for water quality control. Results indicate the dependence of an optimum water quality reservation on agricultural production losses and hydrologic conditions.

  12. Six Sigma Quality Management System and Design of Risk-based Statistical Quality Control.

    PubMed

    Westgard, James O; Westgard, Sten A

    2017-03-01

    Six sigma concepts provide a quality management system (QMS) with many useful tools for managing quality in medical laboratories. This Six Sigma QMS is driven by the quality required for the intended use of a test. The most useful form for this quality requirement is the allowable total error. Calculation of a sigma-metric provides the best predictor of risk for an analytical examination process, as well as a design parameter for selecting the statistical quality control (SQC) procedure necessary to detect medically important errors. Simple point estimates of sigma at medical decision concentrations are sufficient for laboratory applications.

    Maintaining quality in compounded preparations must be a top priority of top management, and it must involve all pharmacy employees. Pharmacy compounding requires the development and maintenance of standard operating procedures to ensure quality and minimize compounding errors. Standard operating procedures are detailed instructions initiated by the pharmacist-in-charge or the quality control officer for the purpose of assuring the reliable, consistent performance of routine tasks involved in formulation development, purchasing, compounding, testing, maintenance, materials handling, quality assurance, and dispensing. Maintaining written standard operation procedures is an important step in assuring that a phamacy has developed a quality compounding practice that meets and/or exceeds United States Pharmacopeial standards.

    A new algorithm for controlling the quality of multiply-refined tetrahedral meshes is presented in this paper. The basic dynamic mesh adaption procedure allows localized grid refinement and coarsening to efficiently capture aerodynamic flow features in computational fluid dynamics problems; however, repeated application of the procedure may significantly deteriorate the quality of the mesh. Results presented show the effectiveness of this mesh quality algorithm and its potential in the area of helicopter aerodynamics and acoustics.

    2013-11-01

    The strategies used in population-based colorectal screening strategies culminate in colonoscopy and consequently the success of these programs largely depends on the quality of this diagnostic test. The main factors to consider when evaluating quality are scientific-technical quality, safety, patient satisfaction, and accessibility. Quality indicators allow variability among hospitals, endoscopy units and endoscopists to be determined and can identify those not achieving recommended standards. In Spain, the working group for colonoscopy quality of the Spanish Society of Gastroenterology and the Spanish Society of Gastrointestinal Endoscopy have recently drawn up a Clinical Practice Guideline that contains the available evidence on the quality of screening colonoscopy, as well as the basic requirements that must be met by endoscopy units and endoscopists carrying out this procedure. The implementation of training programs and screening colonoscopy quality controls are strongly recommended to guarantee the success of population-based colorectal cancer screening.

  1. Air quality and pollution control in Taiwan

    NASA Astrophysics Data System (ADS)

    Fang, Shu-Hwei; Chen, Hsiung-Wen

    Due to limited land and great emphasis on economic growth in the past, Taiwan has an extremely heavy environmental burden. Population density, factory density, as well as densities of motor vehicles are several times higher than those in the United States and Japan. According to the statistics of 1991, the Pollutant Standards Index (PSI) fell mostly in the "moderate" category, i.e., in the range of 50-100. There were 16.25% of the monitored days with PSI above 100, and 0.51% with PSI beyond 200. Suspended particulates were the major pollutant responsible for PSI above 100, followed by carbon monoxide, ozone, and sulfur dioxide. The measures adopted to control air pollution can be divided into four categories, namely law and regulations, control measures on stationary sources, mobile sources and construction projects. The latest amended Air Pollution Control Act was promulgated on 1 February 1992. Several major revisions were introduced to make the amended Act much more stringent than the 1982 amendment, especially on the offenses likely to endanger public health and welfare. In regard to stationary sources, a permit system was enacted to regulate the establishment and alteration of stationary sources. Designated stationary sources are required to be equipped with automatic monitoring facilities. An inspection and enforcement program have expanded to cover more than 10,000 factories. Major control measures for motor vehicles include introducing stringent emission standards for gasoline-fueled vehicles and diesel cars, setting up ratification and approval program for new vehicle model, promoting the inspection/maintenance program on in-used motorcycles and encouraging the use of unleaded and low sulfur fuels. In order to control the pollution caused by construction work, constructors are required to use low-pollution machinery and engineering methods and incorporate pollution prevention into the construction budget.

    Assisted reproductive technology (ART) programs are complex organizations requiring the integration of multiple disciplines. ISO 9001:2008 is a quality management system that is readily adaptable to an ART program. The value that ISO brings to the entire organization includes control of documents, clear delineation of responsibilities of staff members, documentation of the numerous processes and procedures, improvement in tracking and reducing errors, and overall better control of systems. A quality ART program sets quality objectives and monitors their progress. ISO provides a sense of transparency within the organization and clearer understanding of how service is provided to patients. Most importantly, ISO provides the framework to allow for continual improvement.

    PubMed

    Hamrin, Pia; Hoeft, Birgit

    2012-01-01

    The manufacture of infant food is a highly complex process and needs an effective quality control beyond classical in-process parameters and a final microbiological analysis. To ensure a safe end -product, various tools, such as the Hazard Analysis Critical Control Points (HACCP), have been developed to facilitate the management of food safety. Every single infant formula ingredient must have an excellent quality and safety approach because even if an ingredient is used in very small quantities in a single product, serious consequences may arise if the quality and product safety are not taken seriously by the ingredient manufacturer. The purpose of this article was twofold: firstly, to briefly describe existing Quality Management Systems and, secondly, to highlight the consequences of non-quality.

    1982-01-01

    Generic problems in advanced aircraft with advanced control systems which suffer from control sensitivity, sluggish response, and pilot-induced oscillation tendencies are examined, with a view to improving techniques for eliminating the problems in the design phase. Results of two NASA and NASA/AIAA workshops reached a consensus that flying qualities criteria do not match control system development, control system designers are not relying on past experience in their field, ground-based simulation is relied on too heavily, and communications between flying qualities and control systems engineers need improvement. A summation is offered in that hardware and software have outstripped the pilot's capacity to use the capabilities which new aircraft offer. The flying qualities data base is stressed to be dynamic, and continually redefining the man/machine relationships.

  14. Research review: Indoor air quality control techniques

    SciTech Connect

    Fisk, W.J.

    1986-10-01

    Techniques for controlling the concentration of radon, formaldehyde, and combustion products in the indoor air are reviewed. The most effective techniques, which are generally based on limiting or reducing indoor pollutant source strengths, can decrease indoor pollutant concentrations by a factor of 3 to 10. Unless the initial ventilation rate is unusually low, it is difficult to reduce indoor pollutant concentrations more than approximately 50% by increasing the ventilation rate of an entire building. However, the efficiency of indoor pollutant control by ventilation can be enhanced through the use of local exhaust ventilation near concentrated sources of pollutants, by minimizing short circuiting of air from supply to exhaust when pollutant sources are dispersed and, in some situations, by promoting a displacement flow of air and pollutants toward the exhaust. Active air cleaning is also examined briefly. Filtration and electrostatic air cleaning for removal of particles from the indoor air are the most practical and effective currently available techniques of air cleaning. 49 refs., 7 figs.

    Chromatin accessibility is modulated by structural transitions that provide timely access to the genetic and epigenetic information during many essential nuclear processes. These transitions are orchestrated by regulatory proteins that coordinate intricate structural modifications and signalling pathways. In vitro reconstituted chromatin samples from defined components are instrumental in defining the mechanistic details of such processes. The bottleneck to appropriate in vitro analysis is the production of high quality, and quality-controlled, chromatin substrates. In this chapter we describe methods for in vitro chromatin reconstitution and quality control. We highlight the strengths and weaknesses of various approaches, and emphasize quality control steps that ensure reconstitution of a bona fide homogenous chromatin preparation. This is essential for optimal reproducibility and reliability of ensuing experiments using chromatin substrates. PMID:27372747

    2016-01-01

    The lack of sleep, both in quality and quantity, is an increasing problem in modern society, often related to workload and stress. A number of studies have addressed the effects of acute (total) sleep deprivation on postural control. However, up to date, the effects of chronic sleep deficits, either in quantity or quality, have not been analyzed. Thirty healthy adults participated in the study that consisted of registering activity with a wrist actigraph for more than a week before performing a series of postural control tests. Sleep and circadian rhythm variables were correlated and the sum of activity of the least active 5-h period, L5, a rhythm variable, obtained the greater coefficient value with sleep quality variables (wake after sleep onset WASO and efficiency sleep). Cluster analysis was performed to classify subjects into two groups based on L5 (low and high). The balance tests scores used to asses postural control were measured using Biodex Balance System and were compared between the two groups with different sleep quality. The postural tests were divided into dynamic (platform tilt with eyes open, closed and cursor) and static (clinical test of sensory integration). The results showed that during the tests with eyes closed, the group with worse sleep quality had also worse postural control performance. Lack of vision impairs postural balance more deeply in subjects with chronic sleep inefficiency. Chronic poor sleep quality impairs postural control similarly to total sleep deprivation.

  11. CRN5EXP: Expert system for statistical quality control

    NASA Technical Reports Server (NTRS)

    Hentea, Mariana

    1991-01-01

    The purpose of the Expert System CRN5EXP is to assist in checking the quality of the coils at two very important mills: Hot Rolling and Cold Rolling in a steel plant. The system interprets the statistical quality control charts, diagnoses and predicts the quality of the steel. Measurements of process control variables are recorded in a database and sample statistics such as the mean and the range are computed and plotted on a control chart. The chart is analyzed through patterns using the C Language Integrated Production System (CLIPS) and a forward chaining technique to reach a conclusion about the causes of defects and to take management measures for the improvement of the quality control techniques. The Expert System combines the certainty factors associated with the process control variables to predict the quality of the steel. The paper presents the approach to extract data from the database, the reason to combine certainty factors, the architecture and the use of the Expert System. However, the interpretation of control charts patterns requires the human expert's knowledge and lends to Expert Systems rules.

    Keshavan, Anisha; Datta, Esha; McDonough, Ian; Madan, Christopher R; Jordan, Kesshi; Henry, Roland G

    2017-03-29

    Tissue classification plays a crucial role in the investigation of normal neural development, brain-behavior relationships, and the disease mechanisms of many psychiatric and neurological illnesses. Ensuring the accuracy of tissue classification is important for quality research and, in particular, the translation of imaging biomarkers to clinical practice. Assessment with the human eye is vital to correct various errors inherent to all currently available segmentation algorithms. Manual quality assurance becomes methodologically difficult at a large scale - a problem of increasing importance as the number of data sets is on the rise. To make this process more efficient, we have developed Mindcontrol, an open-source web application for the collaborative quality control of neuroimaging processing outputs. The Mindcontrol platform consists of a dashboard to organize data, descriptive visualizations to explore the data, an imaging viewer, and an in-browser annotation and editing toolbox for data curation and quality control. Mindcontrol is flexible and can be configured for the outputs of any software package in any data organization structure. Example configurations for three large, open-source datasets are presented: the 1000 Functional Connectomes Project (FCP), the Consortium for Reliability and Reproducibility (CoRR), and the Autism Brain Imaging Data Exchange (ABIDE) Collection. These demo applications link descriptive quality control metrics, regional brain volumes, and thickness scalars to a 3D imaging viewer and editing module, resulting in an easy-to-implement quality control protocol that can be scaled for any size and complexity of study.

  15. The impact of quality control in RNA-seq experiments

    NASA Astrophysics Data System (ADS)

    Merino, Gabriela A.; Fresno, Cristóbal; Netto, Frederico; Dias Netto, Emmanuel; Pratto, Laura; Fernández, Elmer A.

    2016-04-01

    High throughput mRNA sample sequencing, known as RNA-seq, is as a powerful approach to detect differentially expressed genes starting from millions of short sequence reads. Although several workflows have been proposed to analyze RNA-seq data, the experiment quality control as a whole is not usually considered, thus potentially biasing the results and/or causing information lost. Experiment quality control refers to the analysis of the experiment as a whole, prior to any analysis. It not only inspects the presence of technical effects, but also if general biological assumptions are fulfilled. In this sense, multivariate approaches are crucial for this task. Here, a multivariate approach for quality control in RNA-seq experiments is proposed. This approach uses simple and yet effective well-known statistical methodologies. In particular, Principal Component Analysis was successfully applied over real data to detect and remove outlier samples. In addition, traditional multivariate exploration tools were applied in order to asses several controls that can help to ensure the results quality. Based on differential expression and functional enrichment analysis, here is demonstrated that the information retrieval is significantly enhanced through experiment quality control. Results show that the proposed multivariate approach increases the information obtained from RNA-seq data after outlier samples removal.

  16. Controller Design of Power Quality-Improving Appliances

    SciTech Connect

    Hammerstrom, Donald J.; Zhou, Ning; Lu, Ning

    2007-05-01

    This paper presents an innovative solution to power quality problems using power quality-improving (PQI) appliances. PQI appliances conduct currents that supplement and correct the sum of the other load currents within a premise. From the utility side, the premise housing a PQI appliance thus becomes an improved, if not ideal, utility customer. The PQI appliance improves both harmonic power quality and power factor while performing its normal function, such as heating water. In this paper, the water heater PQI appliance is used as an example to demonstrate the control circuit design and function. Both computer simulation results and laboratory experiment results are presented to demonstrate the effectiveness of the approach. The estimated costs of the PQI controller and of harmonic compensating filters are compared to show that the PQI appliance may be an economic way to provide power quality improvement at the building level.

  17. Space Shuttle flying qualities and flight control system assessment

    NASA Technical Reports Server (NTRS)

    Myers, T. T.; Mcruer, D. T.; Johnston, D. E.

    1982-01-01

    This paper reviews issues, data, and analyses relevant to the longitudinal flying qualities of the Space Shuttle in approach and landing. The manual control of attitude and path are first examined theoretically to demonstrate the unconventional nature of the Shuttle's augmented pitch and path response characteristics. The time domain pitch rate transient response criterion used for design of the Shuttle flight control system is examined in context with data from recent flying qualities experiments and operational aircraft. Questions arising from this examination are addressed through comparisons with MIL-F-8785C and other proposed flying qualities criteria which indicate potential longitudinal flying qualities problems. However, it is shown that these criteria, based largely on data from conventional aircraft, may be inappropriate for assessing the Shuttle.

  20. Current quality assurance concepts and considerations for quality control of in-clinic biochemistry testing.

    PubMed

    Lester, Sally; Harr, K E; Rishniw, Mark; Pion, Paul

    2013-01-15

    Quality assurance is an implied concept inherent in every consumer's purchase of a product or service. In laboratory testing, quality assurance encompasses preanalytic (sampling, transport, and handling prior to testing), analytic (measurement), and postanalytic (reporting and interpretation) factors. Quality-assurance programs require that procedures are in place to detect errors in all 3 components and that the procedures are characterized by both documentation and correction of errors. There are regulatory bodies that provide mandatory standards for and regulation of human medical laboratories. No such regulations exist for veterinary laboratory testing. The American Society for Veterinary Clinical Pathology (ASVCP) Quality Assurance and Laboratory Standards Committee was formed in 1996 in response to concerns of ASVCP members about quality assurance and quality control in laboratories performing veterinary testing. Guidelines for veterinary laboratory testing have been developed by the ASVCP. The purpose of this report was to provide an overview of selected quality-assurance concepts and to provide recommendations for quality control for in-clinic biochemistry testing in general veterinary practice.

    Peters, Jeroen P. M.; Hooft, Lotty; Grolman, Wilko; Stegeman, Inge

    2015-01-01

    Background Randomised Controlled Trials (RCTs) are the preferred study design when comparing therapeutical interventions in medicine. To improve clarity, consistency and transparency of reporting RCTs, the Consolidated Standards of Reporting Trials (CONSORT) statement was developed. Objectives (1) To assess the quality of reports and abstracts of RCTs in otorhinolaryngologic literature by using CONSORT checklists, (2) to compare the quality of reports and abstracts of otorhinolaryngologic RCTs between the top 5 general medical journals and top 5 otorhinolaryngologic journals, and (3) to formulate recommendations for authors and editors of otorhinolaryngologic (‘ENT’) journals. Methods Based on 2012 ISI Web of Knowledge impact factors, the top 5 general medical and ENT journals were selected. On 25 June 2014, using a highly sensitive Cochrane RCT filter and ENT filter, possibly relevant articles since January 1st, 2010 were retrieved and relevant RCTs were selected. We assessed how many CONSORT items were reported adequately in reports and abstracts and compared the two journal types. Results Otorhinolaryngologic RCTs (n = 15) published in general medical journals reported a mean of 92.1% (95% confidence interval: 89.5%–94.7%) of CONSORT items adequately, whereas RCTs (n = 18) published in ENT journals reported a mean of 71.8% (66.7%–76.8%) adequately (p < 0.001). For abstracts, means of 70.0% (63.7%–76.3%) and 32.3% (26.6–38.0%) were found respectively (p < 0.001). Large differences for specific items exist between the two journal types. Conclusion The quality of reporting of RCTs in otorhinolaryngologic journals is suboptimal. RCTs published in general medical journals have a higher quality of reporting than RCTs published in ENT journals. We recommend authors to report their trial according to the CONSORT Statement and advise editors to endorse the CONSORT Statement and implement the CONSORT Statement in the editorial process to ensure more adequate

  8. Machine Vision-Based Measurement Systems for Fruit and Vegetable Quality Control in Postharvest.

    2017-03-14

    Individual items of any agricultural commodity are different from each other in terms of colour, shape or size. Furthermore, as they are living thing, they change their quality attributes over time, thereby making the development of accurate automatic inspection machines a challenging task. Machine vision-based systems and new optical technologies make it feasible to create non-destructive control and monitoring tools for quality assessment to ensure adequate accomplishment of food standards. Such systems are much faster than any manual non-destructive examination of fruit and vegetable quality, thus allowing the whole production to be inspected with objective and repeatable criteria. Moreover, current technology makes it possible to inspect the fruit in spectral ranges beyond the sensibility of the human eye, for instance in the ultraviolet and near-infrared regions. Machine vision-based applications require the use of multiple technologies and knowledge, ranging from those related to image acquisition (illumination, cameras, etc.) to the development of algorithms for spectral image analysis. Machine vision-based systems for inspecting fruit and vegetables are targeted towards different purposes, from in-line sorting into commercial categories to the detection of contaminants or the distribution of specific chemical compounds on the product's surface. This chapter summarises the current state of the art in these techniques, starting with systems based on colour images for the inspection of conventional colour, shape or external defects and then goes on to consider recent developments in spectral image analysis for internal quality assessment or contaminant detection.

  9. A multiple objective optimization approach to quality control

    NASA Technical Reports Server (NTRS)

    Seaman, Christopher Michael

    1991-01-01

    The use of product quality as the performance criteria for manufacturing system control is explored. The goal in manufacturing, for economic reasons, is to optimize product quality. The problem is that since quality is a rather nebulous product characteristic, there is seldom an analytic function that can be used as a measure. Therefore standard control approaches, such as optimal control, cannot readily be applied. A second problem with optimizing product quality is that it is typically measured along many dimensions: there are many apsects of quality which must be optimized simultaneously. Very often these different aspects are incommensurate and competing. The concept of optimality must now include accepting tradeoffs among the different quality characteristics. These problems are addressed using multiple objective optimization. It is shown that the quality control problem can be defined as a multiple objective optimization problem. A controller structure is defined using this as the basis. Then, an algorithm is presented which can be used by an operator to interactively find the best operating point. Essentially, the algorithm uses process data to provide the operator with two pieces of information: (1) if it is possible to simultaneously improve all quality criteria, then determine what changes to the process input or controller parameters should be made to do this; and (2) if it is not possible to improve all criteria, and the current operating point is not a desirable one, select a criteria in which a tradeoff should be made, and make input changes to improve all other criteria. The process is not operating at an optimal point in any sense if no tradeoff has to be made to move to a new operating point. This algorithm ensures that operating points are optimal in some sense and provides the operator with information about tradeoffs when seeking the best operating point. The multiobjective algorithm was implemented in two different injection molding scenarios

  10. Results of a quality control on non-interventional studies

    PubMed Central

    Wörz, Karl; Hundt, Ferdinand

    2011-01-01

    Non-interventional studies (NIS) have for decades been an established part of post-authorisation medicinal research. As early as the mid-nineties, there were at least rudimentary demands for controllable data quality. Beginning with the recommendations of the Federal Institute for Drugs and Medical Devices (BfArM) on the execution of non interventional (observational) studies of 1998 and finally with the guidelines and recommendations for ensuring Good Epidemiological Practice (GEP), with the VFA (Verband der forschenden Arzneimittelhersteller [German Association of Research-Based Pharmaceutical Companies]) – Recommendations for the Improvement of Quality and Transparency of NIS and the joint recommendations of BfArM and PEI (Paul-Ehrlich-Institut) on the execution of NIS, pharmaceutical companies are required to monitor and/or verify quality in the course of a project. According to a survey of pharmaceutical companies 2010, about one third of the companies surveyed to date carry out such quality controls on site, at participating study centres. This report deals with the results of such quality control measures in 4 completed projects. The control rates defined in the respective cohort study plans, the measures carried out on site and any consequent measures, such as adjustment of forms, reduction of consultation time and necessary organisational changes are described. A high level of agreement between the data collected and the original patient documents is found, comparable to that in clinical trials. PMID:21863135

    PubMed Central

    Chakrabarti, Oishee

    2013-01-01

    The cell has an intricate quality control system to protect its mitochondria from oxidative stress. This surveillance system is multi-tiered and comprises molecules that are present inside the mitochondria, in the cytosol, and in other organelles like the nucleus and endoplasmic reticulum. These molecules cross talk with each other and protect the mitochondria from oxidative stress. Oxidative stress is a fundamental part of early disease pathogenesis of neurodegenerative diseases. These disorders also damage the cellular quality control machinery that protects the cell against oxidative stress. This exacerbates the oxidative damage and causes extensive neuronal cell death that is characteristic of neurodegeneration. PMID:24288463

    Pharmaceutical preparations, particularly as a "secret recipe" of traditional Chinese medicine in medical institutions, are the product of China's medical and health industry, and they are also an important means of competing of different medical institutions. Although pharmaceutical preparations have advantages and characteristics than institutes for drug and pharmaceutical companies, the quality standards of pharmaceutical preparations in medical institutions has not reached the desired level over the years. As we all know, the quality of pharmaceutical preparations is important to ensure the efficacy, especially under the environment of people pay more sttention on drug safety and effectiveness and contry increase emphasis on the stste of pharmaceutical preparations. In view of this, we will improve the grade, stability, and clinical efficacy of pharmaceutical preparations by the advanced equipment, testing instruments and the process dynamic quality control technology. Finally, we hope we can provide new ideas for the quality control of pharmaceutical preparations.

    2017-03-06

    The potential of quantitative phase imaging (QPI) with digital holographic microscopy (DHM) for quantification of cell culture quality was explored. Label-free QPI of detached single cells in suspension was performed by Michelson interferometer-based self-interference DHM. Two pancreatic tumor cell lines were chosen as cellular model and analyzed for refractive index, volume, and dry mass under varying culture conditions. Firstly, adequate cell numbers for reliable statistics were identified. Then, to characterize the performance and reproducibility of the method, we compared results from independently repeated measurements and quantified the cellular response to osmolality changes of the cell culture medium. Finally, it was demonstrated that the evaluation of QPI images allows the extraction of absolute cell parameters which are related to cell layer confluence states. In summary, the results show that QPI enables label-free imaging cytometry, which provides novel complementary integral biophysical data sets for sophisticated quantification of cell culture quality with minimized sample preparation. © 2017 International Society for Advancement of Cytometry.

  20. Quality controls in integrative approaches to detect errors and inconsistencies in biological databases.

    PubMed

    Ghisalberti, Giorgio; Masseroli, Marco; Tettamanti, Luca

    2010-03-25

    Numerous biomolecular data are available, but they are scattered in many databases and only some of them are curated by experts. Most available data are computationally derived and include errors and inconsistencies. Effective use of available data in order to derive new knowledge hence requires data integration and quality improvement. Many approaches for data integration have been proposed. Data warehousing seams to be the most adequate when comprehensive analysis of integrated data is required. This makes it the most suitable also to implement comprehensive quality controls on integrated data. We previously developed GFINDer (http://www.bioinformatics.polimi.it/GFINDer/), a web system that supports scientists in effectively using available information. It allows comprehensive statistical analysis and mining of functional and phenotypic annotations of gene lists, such as those identified by high-throughput biomolecular experiments. GFINDer backend is composed of a multi-organism genomic and proteomic data warehouse (GPDW). Within the GPDW, several controlled terminologies and ontologies, which describe gene and gene product related biomolecular processes, functions and phenotypes, are imported and integrated, together with their associations with genes and proteins of several organisms. In order to ease maintaining updated the GPDW and to ensure the best possible quality of data integrated in subsequent updating of the data warehouse, we developed several automatic procedures. Within them, we implemented numerous data quality control techniques to test the integrated data for a variety of possible errors and inconsistencies. Among other features, the implemented controls check data structure and completeness, ontological data consistency, ID format and evolution, unexpected data quantification values, and consistency of data from single and multiple sources. We use the implemented controls to analyze the quality of data available from several different biological

    Based on theoretic management and quality control of the project, this paper summarizes the 3 major management modes in the national schistosomiasis control programme of China, and the health system management mechanisms under the guidance of national legislation, national programme and national standard and regulation. It is revealed that scientific assessment and assurance of the quality of each control programme is one of the highlighted concerns in the management mode of schistosomiasis control in China after a case study on mollusciciding project. Therefore, it is recommended that the actions, including management of every step in the project management of schistosomiasis control, formulation of operation procedure for each control programme and standardization of the working flow for professional staff, are not only a prerequistite to achievment-based evaluation, but also the key to ensure the quality of every control intervention and present the actual control effect.

    In the present paper, the simultaneous quantification of two analytes showing strongly overlapped chromatographic peaks (alpha = 1.02), under the assumption that both available equipment and training of the laboratory staff are basic, is studied. A pharmaceutical preparation (Mutabase) containing two drugs of similar physicochemical properties (amitriptyline and perphenazine) is selected as case of study. The assays are carried out under realistic working conditions (i.e. routine testing laboratories). Uncertainty considerations are introduced in the study. A partial least squares model is directly applied to the chromatographic data (with no previous signal transformation) to perform quality control of the pharmaceutical formulation. Under the adequate protocol, the relative error in prediction of analytes is within the tolerances found in the pharmacopeia (10%). For spiked samples simulating formulation mistakes, the errors found have the same magnitude and sign to those provoked.

  3. Uncertainty-based internal quality control. Harmonization considerations.

    Three main quality aspects for analytical laboratories are internal method validation, internal quality control (IQC), and sample result uncertainty. Unfortunately, in the past they have been used in a nonharmonized way. The most universal IQC tool is the mean chart, but some criteria used to fix their control limits do not fit the real nature of analytical results. A new approach for fixing these limits is proposed (the u-approach). The key is the combined uncertainty, u, obtained from the method validation information, also used for estimating the sample result uncertainty. A comparative study on "in-control" simulated, bibliographic, and real laboratory data suggests that the u-approach is more reliable than other well-established criteria. In addition, the u-approach mean chart emerges as an IQC tool, consistent with chemical assays, which harmonizes the validation-control-uncertainty process.

    It is pointed out that in-process tests to verify quality and detect discrepant propellant which could compromise motor performance are essential elements of the solid composite propellant manufacturing process. The successful performance of the 260SL-1 and 260SL-2 motors aptly verified the controls used for manufacturing the propellant. The present investigation is concerned with the selected control parameters, and their relationships to composition and final propellant properties. Control performance is evaluated by comparison with processing data experienced in the manufacture of the propellant for the 260SL-1 motor. It is found that the in-process quality verification controls utilized in the propellant manufacturing process for the 260-in. diameter motor contributed significantly to the confidence of successful and predictable motor performance.

    Through the continuous efforts of several generations, China has become one of the few countries in the world that is capable of independently addressing all the requirements by the Expanded Program on Immunization. Regulatory science is applied to continuously improve the vaccine regulatory system. Passing the prequalification by WHO has allowed Chinese vaccine products to go global. Chinese vaccine products not only secure disease prevention and control domestically but also serve the needs for international public health. This article describes the history of Chinese vaccine development, the current situation of Chinese vaccine industry and its contribution to the prevention and control of infectious diseases. We also share our experience of national quality control and vaccine regulation during the past decades. China's experience in vaccine development and quality control can benefit other countries and regions worldwide, including the developing countries.

    Employees with sleep disturbance are at increased risk of disease. Exercise is believed to be effective for improving sleep quality, but few studies have been conducted. This study investigated the effects of a 24-week worksite exercise/behavioral intervention on self-rated sleep quality, via the Pittsburgh Sleep Quality Index (PSQI), in 73 employees. Greater post-test improvements in the PSQI (-2.0 +/- 2.6 vs. -1.3 +/- 2.7 points, p = .006, and -16 +/- 61 vs. -1 +/- 76%, p = .02) were found in treatment versus controls, and in women versus men (by -2.7 points [-5.0 to -0.3 points, p = .03], and by -72% [-142 to -2%, p = .04]). Similar results were found in the shift worker subgroup. Changes in sleep scores were not significantly related to baseline characteristics, changes in psychological health or quality-of-life scores, or level of exercise compliance.

    1995-02-01

    Recent advances in video microscopy in the field of cytopathology need to define in detail requirements for rigorous technical quality control of DNA analysis. This study deals with the influence of both quality and calibration of instrumentation on DNA content measurements. Quality control of instrumentation in stability, linearity, and shading estimations has been achieved for two SAMBATM2005 (ALCATEL-TITN-Answare/France) image analysis systems by using prototype reference standard slide and Feulgen-stained rat liver imprints. The accuracy of the various conditions of work has been expressed as the CV of integrated optical density (IOD) and varied from 1.5% to 5.4%. These results demonstrate the dependence of the accuracy of measurements on the conditions for calibration of the instrument. Moreover, this work shows that each system can be characterized by its specific answer and all the systems don't really offer acceptable conditions for nuclear DNA content determination.

  11. Protein quality control, retention, and degradation at the endoplasmic reticulum.

    PubMed

    Benyair, Ron; Ron, Efrat; Lederkremer, Gerardo Z

    2011-01-01

    In order to maintain proper cellular functions, all living cells, from bacteria to mammalian cells, must carry out a rigorous quality control process in which nascent and newly synthesized proteins are examined. An important role of this process is to protect cells against pathological accumulation of unfolded and misfolded proteins. The endoplasmic reticulum (ER) has evolved as a staging ground for secretory protein synthesis with distinct sites for entry, quality control, and exit. In the ER, most proteins are N-glycosylated, a posttranslational modification that defines the quality control pathway that the protein will undergo. The folding state of glycoproteins is revealed by specific modifications of their N-glycans. Regardless of size and posttranslational modifications, the folding states of all proteins must be identified as unfolded, properly folded, or terminally misfolded and accordingly subjected to ER retention and continued folding attempts, export and maturation, or retrotranslocation to the cytosol for degradation. These processes involve specialized machineries that utilize molecular chaperones, protein- and N-glycan-modifying enzymes, and lectins for protein folding and quality control and ubiquitination and degradation machineries for disposal. All these machineries are regulated by a signaling pathway, the unfolded protein response, which upregulates ER functions when under the stress of high protein load. Here, we describe the molecular mechanisms that are implicated and discuss recent data that underline the importance of compartmentalization in the segregation of the various functions of the ER for their correct function.

    A well-documented, publicly available, global data set of surface ocean carbon dioxide (CO2) parameters has been called for by international groups for nearly two decades. The Surface Ocean CO2 Atlas (SOCAT) project was initiated by the international marine carbon science community in 2007 with the aim of providing a comprehensive, publicly available, regularly updated, global data set of marine surface CO2, which had been subject to quality control (QC). Many additional CO2 data, not yet made public via the Carbon Dioxide Information Analysis Center (CDIAC), were retrieved from data originators, public websites and other data centres. All data were put in a uniform format following a strict protocol. Quality control was carried out according to clearly defined criteria. Regional specialists performed the quality control, using state-of-the-art web-based tools, specially developed for accomplishing this global team effort. SOCAT version 1.5 was made public in September 2011 and holds 6.3 million quality controlled surface CO2 data points from the global oceans and coastal seas, spanning four decades (1968-2007). Three types of data products are available: individual cruise files, a merged complete data set and gridded products. With the rapid expansion of marine CO2 data collection and the importance of quantifying net global oceanic CO2 uptake and its changes, sustained data synthesis and data access are priorities.

    The mechanisms of protein quality control in hepatocytes in cases of alcoholic hepatitis (AH) including ufmylation, FAT10ylation, metacaspase 1 (Mca1), ERAD (endoplasmic reticulum-associated degradation), JUNQ (juxta nuclear quality control), IPOD (insoluble protein deposit) autophagocytosis, and ER stress are reviewed. The Mallory-Denk body (MDB) formation develops in the hepatocytes in alcoholic hepatitis as a consequence of the failure of these protein quality control mechanisms to remove misfolded and damaged proteins and to prevent MDB aggresome formation within the cytoplasm of hepatocytes. The proteins involved in the quality control pathways are identified, quantitated, and visualized by immunofluorescent antibody staining of liver biopsies from patients with AH. Quantification of the proteins are achieved by measuring the fluorescent intensity using a morphometric system. Ufmylation and FAT10ylation pathways were downregulated, Mca1 pathways were upregulated, autophagocytosis was upregulated, and ER stress PERK (protein kinase RNA-like endoplasmic reticulum kinase) and CHOP (CCAAT/enhancer-binding protein homologous protein) mechanisms were upregulated.

  2. Incorporating Quality Control Information in the Sensor Web

    NASA Astrophysics Data System (ADS)

    Devaraju, Anusuriya; Kunkel, Ralf; Bogena, Heye

    2013-04-01

    The rapid development of sensing technologies had led to the creation of large amounts of heterogeneous environmental observations. The Sensor Web provides a wider access to sensors and observations via common protocols and specifications. Observations typically go through several levels of quality control, and aggregation before they are made available to end-users. Raw data are usually inspected, and related quality flags are assigned. Data are gap-filled, and errors are removed. New data series may also be derived from one or more corrected data sets. Until now, it is unclear how these kinds of information can be captured in the Sensor Web Enablement (SWE) framework. Apart from the quality measures (e.g., accuracy, precision, tolerance, or confidence), the levels of observational series, the changes applied, and the methods involved must be specified. It is important that this kind of quality control information is well described and communicated to end-users to allow for a better usage and interpretation of data products. In this paper, we describe how quality control information can be incorporated into the SWE framework. Concerning this, first, we introduce the TERENO (TERrestrial ENvironmental Observatories), an initiative funded by the large research infrastructure program of the Helmholtz Association in Germany. The main goal of the initiative is to facilitate the study of long-term effects of climate and land use changes. The TERENO Online Data RepOsitORry (TEODOOR) is a software infrastructure that supports acquisition, provision, and management of observations within TERENO via SWE specifications and several other OGC web services. Next, we specify changes made to the existing observational data model to incorporate quality control information. Here, we describe the underlying TERENO data policy in terms of provision and maintenance issues. We present data levels, and their implementation within TEODOOR. The data levels are adapted from those used by

    Introduction Publishing protocols of randomized controlled trials (RCT) facilitates a more detailed description of study rational, design, and related ethical and safety issues, which should promote transparency. Little is known about how the practice of publishing protocols developed over time. Therefore, this study describes the worldwide trends in volume and methodological quality of published RCT protocols. Methods A systematic search was performed in PubMed and EMBASE, identifying RCT protocols published over a decade from 1 September 2001. Data were extracted on quality characteristics of RCT protocols. The primary outcome, methodological quality, was assessed by individual methodological characteristics (adequate generation of allocation, concealment of allocation and intention-to-treat analysis). A comparison was made by publication period (First, September 2001- December 2004; Second, January 2005-May 2008; Third, June 2008-September 2011), geographical region and medical specialty. Results The number of published RCT protocols increased from 69 in the first, to 390 in the third period (p<0.0001). Internal medicine and paediatrics were the most common specialty topics. Whereas most published RCT protocols in the first period originated from North America (n = 30, 44%), in the second and third period this was Europe (respectively, n = 65, 47% and n = 190, 48%, p = 0.02). Quality of RCT protocols was higher in Europe and Australasia, compared to North America (OR = 0.63, CI = 0.40–0.99, p = 0.04). Adequate generation of allocation improved with time (44%, 58%, 67%, p = 0.001), as did concealment of allocation (38%, 53%, 55%, p = 0.03). Surgical protocols had the highest quality among the three specialty topics used in this study (OR = 1.94, CI = 1.09–3.45, p = 0.02). Conclusion Publishing RCT protocols has become popular, with a five-fold increase in the past decade. The quality of published RCT protocols also improved, although variation between

  5. Soil moisture and strength index for earthwork construction quality control

    NASA Astrophysics Data System (ADS)

    Sawangsuriya, A.; Wachiraporn, S.; Sramoon, W.

    2015-09-01

    This paper presents the implementation of soil moisture and strength index measurements for earthwork construction quality control as well as a link between the in situ testing and structural property of earthen materials. Use of the convenient Dynamic Cone Penetrometer (DCP) in conjunction with conventional moisture-density measurements enhances quality control by achieving acceptable level of compaction, more uniform structural properties, and aids developing a controlled design parameter during the earthwork construction. Soil strength in term of DCP index normalized by the deviation of compaction moisture content from the optimum moisture content is proposed as performance criteria for a variety of engineered earth fills and special engineering assessment, prevention, and mitigation of geohazards e.g. earthen flood defense embankments.

    A study on structural quality control of Swiss-type cheese with ultrasound is presented. We used a longitudinal mode pulse-echo setup using 1-2MHz ultrasonic frequencies to detect cheese-eyes and ripening induced cracks. Results show that the ultrasonic method posses good potential to monitor the cheese structure during the ripening process. Preliminary results indicate that maturation stage could be monitored with ultrasonic velocity measurements. Further studies to verify the method's on-line potential to detect low-structural-quality cheeses are planned.
