Analytical laboratory quality control charting  

SciTech Connect

In life the importance of setting goals is stressed. The desired end result must be envisioned to chart a path and determine indicators to provide feedback on the process. Quality does not happen by accident but is achieved through a constant process of setting goals, process development, monitoring process indicators, fine tuning the process, and achieving results. These goals are to be focused and clearly measurable. In industry and life the setting of goals with clear process indicators is often difficult because of the variable end result and scarcity of measurements. Laboratories are fortunate in that they have a plethora of measurements with known or desired end results (controls) to monitor the process and give instantaneous feedback on quality. A key quality tool used by the laboratory to monitor and evaluate the lab processes is control charting. When properly utilized Quality Control (QC) Charts allow labs to be proactive in addressing problems rather than reactive. Several methods are available for control charting and some are listed in the references/information sources. The content for this paper is based on the control-charting program utilized at the Department of Energy's Fernald site. This control-charting program has specific areas of emphasis, simple charts, trend analyses, and effective follow-up.

[Proposed recommendations for the practical use of internal quality controls (IQC) in a medical biology laboratory].  

PubMed

We propose a set of recommendations and practices to optimize the use of quality control of medical biology examinations. The fundamentals are reviewed: definition of a series of analysis, IQC at one or more level, Westgard alert rules and rejection, practical remedial actions to take for the technician, corrective and preventive actions to be implemented by the biologist. We have also formalized three flowcharts to guide the technician in their daily practice to ensure analytical quality of investigations carried out. These decision trees are the result of the experience submitted by an accredited and professional laboratory attentive to the ongoing improvement of IQC. This article can provide useful assistance to biologists for accreditation but also aims to foster collaboration reliable medical biology laboratory at the appropriate management of patients.

Analytical laboratory quality audits  

SciTech Connect

Analytical Laboratory Quality Audits are designed to improve laboratory performance. The success of the audit, as for many activities, is based on adequate preparation, precise performance, well documented and insightful reporting, and productive follow-up. Adequate preparation starts with definition of the purpose, scope, and authority for the audit and the primary standards against which the laboratory quality program will be tested. The scope and technical processes involved lead to determining the needed audit team resources. Contact is made with the auditee and a formal audit plan is developed, approved and sent to the auditee laboratory management. Review of the auditee's quality manual, key procedures and historical information during preparation leads to better checklist development and more efficient and effective use of the limited time for data gathering during the audit itself. The audit begins with the opening meeting that sets the stage for the interactions between the audit team and the laboratory staff. Arrangements are worked out for the necessary interviews and examination of processes and records. The information developed during the audit is recorded on the checklists. Laboratory management is kept informed of issues during the audit so there are no surprises at the closing meeting. The audit report documents whether the management control systems are effective. In addition to findings of nonconformance, positive reinforcement of exemplary practices provides balance and fairness. Audit closure begins with receipt and evaluation of proposed corrective actions from the nonconformances identified in the audit report. After corrective actions are accepted, their implementation is verified. Upon closure of the corrective actions, the audit is officially closed.

Eur J Clin Chem Clin Biochem 1997 in medical biochemical laboratories included in the First Croatia health project, Primary health care subproject, has been met by the marketing approach to the project. The equipment ensuring implementation of the complete laboratory program (NN/96), more accurate and precise analytical procedures, and higher reliability of laboratory test results compared with previous equipment, has been purchased by an international tender. Uniform technology and methods of analysis have ensured high standards of good laboratory services, yielding test results than can be transferred from primary to secondary health care level. The new equipment has improved organization between central and detached medical biochemistry laboratory units, while the high quality requirement has led to improvement in the staff structure, e.g., medical biochemists have been employed in laboratories that had previously worked without such a professional. Equipment renewal has been accompanied by proper education for all levels of PHC professionals. PMID:11040533

Quality in the molecular microbiology laboratory.  

PubMed

In the clinical microbiology laboratory advances in nucleic acid detection, quantification, and sequence analysis have led to considerable improvements in the diagnosis, management, and monitoring of infectious diseases. Molecular diagnostic methods are routinely used to make clinical decisions based on when and how to treat a patient as well as monitor the effectiveness of a therapeutic regime and identify any potential drug resistant strains that may impact on the long term patient treatment program. Therefore, confidence in the reliability of the result provided by the laboratory service to the clinician is essential for patient treatment. Hence, suitable quality assurance and quality control measures are important to ensure that the laboratory methods and service meet the necessary regulatory requirements both at the national and international level. In essence, the modern clinical microbiology laboratory ensures the appropriateness of its services through a quality management system that monitors all aspects of the laboratory service pre- and post-analytical-from patient sample receipt to reporting of results, from checking and upholding staff competency within the laboratory to identifying areas for quality improvements within the service offered. For most European based clinical microbiology laboratories this means following the common International Standard Organization (ISO9001) framework and ISO15189 which sets out the quality management requirements for the medical laboratory (BS EN ISO 15189 (2003) Medical laboratories-particular requirements for quality and competence. British Standards Institute, Bristol, UK). In the United States clinical laboratories performing human diagnostic tests are regulated by the Centers for Medicare and Medicaid Services (CMS) following the requirements within the Clinical Laboratory Improvement Amendments document 1988 (CLIA-88). This chapter focuses on the key quality assurance and quality control requirements within the modern microbiology laboratory providing molecular diagnostics. PMID:23104281

Statistical Methods for Establishing Quality Control Ranges for Antibacterial Agents in Clinical and Laboratory Standards Institute Susceptibility Testing?  

PubMed Central

Quality control (QC) ranges for antimicrobial agents against QC strains for both dilution and disk diffusion testing are currently set by the Clinical and Laboratory Standards Institute (CLSI), using data gathered in predefined structured multilaboratory studies, so-called tier 2 studies. The ranges are finally selected by the relevant CLSI subcommittee, based largely on visual inspection and a few simple rules. We have developed statistical methods for analyzing the data from tier 2 studies and applied them to QC strain-antimicrobial agent combinations from 178 dilution testing data sets and 48 disk diffusion data sets, including a method for identifying possible outlier data from individual laboratories. The methods are based on the fact that dilution testing MIC data were log normally distributed and disk diffusion zone diameter data were normally distributed. For dilution testing, compared to QC ranges actually set by CLSI, calculated ranges were identical in 68% of cases, narrower in 7% of cases, and wider in 14% of cases. For disk diffusion testing, calculated ranges were identical to CLSI ranges in 33% of cases, narrower in 8% of cases, and 1 to 2 mm wider in 58% of cases. Possible outliers were detected in 8% of diffusion test data but none of the disk diffusion data. Application of statistical techniques to the analysis of QC tier 2 data and the setting of QC ranges is relatively simple to perform on spreadsheets, and the output enhances the current CLSI methods for setting of QC ranges.

Quality and safety aspects in histopathology laboratory  

PubMed Central

Histopathology is an art of analyzing and interpreting the shapes, sizes and architectural patterns of cells and tissues within a given specific clinical background and a science by which the image is placed in the context of knowledge of pathobiology, to arrive at an accurate diagnosis. To function effectively and safely, all the procedures and activities of histopathology laboratory should be evaluated and monitored accurately. In histopathology laboratory, the concept of quality control is applicable to pre-analytical, analytical and post-analytical activities. Ensuring safety of working personnel as well as environment is also highly important. Safety issues that may come up in a histopathology lab are primarily those related to potentially hazardous chemicals, biohazardous materials, accidents linked to the equipment and instrumentation employed and general risks from electrical and fire hazards. This article discusses quality management system which can ensure quality performance in histopathology laboratory. The hazards in pathology laboratories and practical safety measures aimed at controlling the dangers are also discussed with the objective of promoting safety consciousness and the practice of laboratory safety.

[Total quality management in laboratory medicine].  

PubMed

The German Public Health will be continuously challenged in the future. It has to be assumed that modified managed care will not only take place sporadically. Thus, quality aspects of services gain more and more significance. Only suppliers will be successful who can offer services of highest quality at lowest prices. Quality in a comprehensive sense has to be substantiated in the near future. It is recommended to apply industry proven models also in public health service. Medical laboratories can be pioneers in this field as they have been already in the past. All previously proposed procedures can not describe quality of results comprehensively. They are based to a high degree on external control. Total quality management, however, represents a comprehensive approach. Principles are zero-defect approach, customer orientation and system management. Quality is given in the sense of TQM if the customer is permanently satisfied with the service of the supplier. In such a way, the customer defines quality of service. A customer is everyone who receives products or services. TQM overcomes the drawbacks of quality management systems, which are strongly formal and oriented by external control, as accreditation (EN 45,000) or certification (ISO 9000). Competition between hospitals is a declared goal of German health politics because usually quality is increased and cost decreased as a consequence. Competition means also comparison of services. TQM emphasizes benchmarking especially among the best suppliers. PMID:10028601

Quality assurance in a large reference laboratory.  

PubMed

The success of a quality assurance system is contingent on close adherence to each protocol, from preparation of the patient to issuance of the final result. In the event that the system experiences failures at any point, the quality of laboratory data may be jeopardized. Again, the system requires support not just from management and personnel employed at the technical level, but from the entire organization. It requires a complete commitment to quality and to the provision of a high level of service. Such quality assurance programs have been highly successful in the manufacturing industry. For an example, one need look no further than the domination of certain world markets by Japanese industries. Their commitment to quality and their system-wide quality control efforts have been essential to the success and growth of their organizations. Currently, systems that provide high levels of quality assurance are under scrutiny in an effort to reduce costs. As more effort is placed into monitoring an organization's quality, the expenditure of non-revenue producing dollars increases. A large organization should question these expenditures. However, when evaluating such a program, it should be realized that the costs associated with the pursuit of quality are often offset by savings realized through improved processes. Further, quality is a salable commodity. Its lack may be costly. According to Westgard et al., costs of quality can be grouped into prevention costs, appraisal costs, and failure costs. Prevention costs include those costs incurred through the development of sound analytic procedures and adequate training of technical personnel. Appraisal costs comprise those costs incurred as a result of challenging the analytic procedure as well as the entire system. Failure costs represent the dollars spent when out-of-control assays have to be repeated. An important step in evaluating potential savings produced by a quality control program is assigning a dollar value to the cost of repeating an assay. In general, as the quality of an organization's product increases, the expense of providing the product decreases. Likewise, as productivity increases, the cost of testing decreases. Increased quality and productivity provide a higher percentage of profit. As the profitability of an organization increases, the additional resources required to investigate new methods, themselves a valuable contribution to quality assurance, are provided.(ABSTRACT TRUNCATED AT 400 WORDS) PMID:3791912

Methods of analysis by the U.S. Geological Survey National Water Quality Laboratory; processing, taxonomy, and quality control of benthic macroinvertebrate samples  

USGS Publications Warehouse

Qualitative and quantitative methods to process benthic macroinvertebrate (BMI) samples have been developed and tested by the U.S. Geological Survey?s National Water Quality Laboratory Biological Group. The qualitative processing method is based on visually sorting a sample for up to 2 hours. Sorting focuses on attaining organisms that are likely to result in taxonomic identifications to lower taxonomic levels (for example, Genus or Species). Immature and damaged organisms are also sorted when they are likely to result in unique determinations. The sorted sample remnant is scanned briefly by a second person to determine if obvious taxa were missed. The quantitative processing method is based on a fixed-count approach that targets some minimum count, such as 100 or 300 organisms. Organisms are sorted from randomly selected 5.1- by 5.1-centimeter parts of a gridded subsampling frame. The sorted remnant from each sample is resorted by a second individual for at least 10 percent of the original sort time. A large-rare organism search is performed on the unsorted remnant to sort BMI taxa that were not likely represented in the sorted grids. After either qualitatively or quantitatively sorting the sample, BMIs are identified by using one of three different types of taxonomic assessment. The Standard Taxonomic Assessment is comparable to the U.S. Environmental Protection Agency Rapid Bioassessment Protocol III and typically provides Genus- or Species-level taxonomic resolution. The Rapid Taxonomic Assessment is comparable to the U.S. Environmental Protection Agency Rapid Bioassessment Protocol II and provides Familylevel and higher taxonomic resolution. The Custom Taxonomic Assessment provides Species-level resolution whenever possible for groups identified to higher taxonomic levels by using the Standard Taxonomic Assessment. The consistent use of standardized designations and notes facilitates the interpretation of BMI data within and among water-quality studies. Taxonomic identifications are quality assured by verifying all referenced taxa and randomly reviewing 10 percent of the taxonomic identifications performed weekly by Biological Group taxonomists. Taxonomic errors discovered during this review are corrected. BMI data are reviewed for accuracy and completeness prior to release. BMI data are released phylogenetically in spreadsheet format and unprocessed abundances are corrected for laboratory and field subsampling when necessary.

On the use of (127)Xe standards for the quality control of CTBTO noble gas stations and support laboratories.  

PubMed

(127)Xe has a longer half-life than (131m)Xe, it can be easily purely produced and it is present in the environment at very low level. For these reasons, (127)Xe is supposed to be a convenient quality control radionuclide for remote noble gas stations of the International Monitoring System (IMS) network. As CEA/DAM has recently developed two new photon/electron setups for low-level detection of (131m)Xe, (133m)Xe, (133)Xe and (135)Xe, we took the opportunity to test these setups for the measurement of a (127)Xe standard. The results and a detailed description of these measurements are presented in this paper. They illustrate the complexity of (127)Xe decay, emitting simultaneously several ?, X-rays, conversion electrons and Auger electrons; this results in highly summated coincidence spectra. The measurements performed provide precise electron energy calibration of the setups. The count rate of electrons in coincidence with iodine K? X-rays was found to be surprisingly low, leading to the study of electron-gated photon spectrum. Finally, a comparison of three photon/electron coincidence spectra obtained with three different setups is given. The use of (127)Xe as a standard for energy calibration of IMS noble gas station is possible, but it appears to be quite complicated for efficiency check of noble gas station equipped with ?/? detectors.

[The network of official medicines control laboratories].  

PubMed

Licensing, control and surveillance by competent authorities is the basis for ensuring efficacy, safety and quality of medicines in Europe. The control of the quality of medicines by national control laboratories, known as Official Medicines Control Laboratories (OMCLs) is an essential step in this process; it encompasses controls before and after granting a marketing authorisation. For certain groups of biomedical medicines (vaccines for human and veterinary use, medicines derived from human plasma) even each batch is controlled before it can be placed on the market. As single OMCLs would not be able to cope with their task, given the large number and diversity of medicines, in 1994 the OMCL network was founded upon initiative of the European Directorate for the Quality of Medicines & HealthCare, in close collaboration with the Commission of the European Union. Currently 68 OMCLs from 39 countries are part of the network. Prerequisite for the smooth operation of the OMCL network is the harmonisation of the quality management system of the individual OMCLs, based on the ISO 17025 standard, internal guidelines and the European Pharmacopoeia. Compliance with these standards is checked through regular audits, thus creating the basis for mutual recognition of test results. The collaboration in the OMCL network for the surveillance of the medicines market, the official control authority batch release and the fight against counterfeiting and illegal medicines enables OMCLs to keep pace with the developments in the field of medicines and to control the broad spectrum of medicines. In the 20 years since its start, the OMCL network has become a European success story. PMID:25192832

Laboratory Exercise: What Controls Rheology?  

NSDL National Science Digital Library

A short laboratory exercise, conducted by students, is used to illustrate the multiple factors that contribute to rocks' varied responses to deformation. Analogue materials (play-doh, notebook springs, butter, silly putty, plastic bags, etc.) are used to illustrate many of the controlling factors such as lithology, stress, temperature, confining pressure, strain rate, preexisting weaknesses, and accumulated strain. The analogue experiments are presented in conjunction with parallel data from deformation experiments and field studies. The tandem presentation of analogue experiment and real data requires the students to obtain a natural "feel" for rheologic parameters and more exhaustively analyze the important conclusions obtained from field and deformation experiment data.

Quality Assurance of RNA Expression Profiling in Clinical Laboratories  

PubMed Central

RNA expression profiles are increasingly used to diagnose and classify disease, based on expression patterns of as many as several thousand RNAs. To ensure quality of expression profiling services in clinical settings, a standard operating procedure incorporates multiple quality indicators and controls, beginning with preanalytic specimen preparation and proceeding thorough analysis, interpretation, and reporting. Before testing, histopathological examination of each cellular specimen, along with optional cell enrichment procedures, ensures adequacy of the input tissue. Other tactics include endogenous controls to evaluate adequacy of RNA and exogenous or spiked controls to evaluate run- and patient-specific performance of the test system, respectively. Unique aspects of quality assurance for array-based tests include controls for the pertinent outcome signatures that often supersede controls for each individual analyte, built-in redundancy for critical analytes or biochemical pathways, and software-supported scrutiny of abundant data by a laboratory physician who interprets the findings in a manner facilitating appropriate medical intervention. Access to high-quality reagents, instruments, and software from commercial sources promotes standardization and adoption in clinical settings, once an assay is vetted in validation studies as being analytically sound and clinically useful. Careful attention to the well-honed principles of laboratory medicine, along with guidance from government and professional groups on strategies to preserve RNA and manage large data sets, promotes clinical-grade assay performance.

Quality control in gastrointestinal surgery.  

PubMed

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.

Cost Effectiveness of Adopted Quality Requirements in Hospital Laboratories  

PubMed Central

Background The present study was designed in quasi-experiment to assess adoption of the essential clauses of particular clinical laboratory quality management requirements based on international organization for standardization (ISO 15189) in hospital laboratories and to evaluate the cost effectiveness of compliance to ISO 15189. Methods: The quality management intervention based on ISO 15189 was conceded through three phases; pre – intervention phase, Intervention phase and Post-intervention phase. Results: In pre-intervention phase the compliance to ISO 15189 was 49% for study group vs. 47% for control group with P value 0.48, while the post intervention results displayed 54% vs. 79% for study group and control group respectively in compliance to ISO 15189 and statistically significant difference (P value 0.00) with effect size (Cohen’s d) of (0.00) in pre-intervention phase and (0.99) in post – intervention phase. The annual average cost per-test for the study group and control group was 1.80 ± 0.25 vs. 1.97 ± 0.39, respectively with P value 0.39 whereas the post-intervention results showed that the annual average total costs per-test for study group and control group was 1.57 ± 0.23 vs 2.08 ± 0.38, P value 0.019 respectively, with cost-effectiveness ratio of (0.88) in pre -intervention phase and (0.52) in post-intervention phase. Conclusion: The planned adoption of quality management requirements (QMS) in clinical laboratories had great effect to increase the compliance percent with quality management system requirement, raise the average total cost effectiveness, and improve the analytical process capability of the testing procedure.

USGS Publications Warehouse

An analytical method for the determination of haloacetic acid formation potential of water samples has been developed by the U.S. Geological Survey California Water Science Center Sacramento Laboratory. The haloacetic acid formation potential is measured by dosing water samples with chlorine under specified conditions of pH, temperature, incubation time, darkness, and residual-free chlorine. The haloacetic acids formed are bromochloroacetic acid, bromodichloroacetic acid, dibromochloroacetic acid, dibromoacetic acid, dichloroacetic acid, monobromoacetic acid, monochloroacetic acid, tribromoacetic acid, and trichloroacetic acid. They are extracted, methylated, and then analyzed using a gas chromatograph equipped with an electron capture detector. Method validation experiments were performed to determine the method accuracy, precision, and detection limit for each of the compounds. Method detection limits for these nine haloacetic acids ranged from 0.11 to 0.45 microgram per liter. Quality-control practices include the use of blanks, quality-control samples, calibration verification standards, surrogate recovery, internal standard, matrix spikes, and duplicates.

State Public Health Laboratory System Quality Improvement Activities  

PubMed Central

The Association of Public Health Laboratories (APHL) and the APHL Laboratory Systems and Standards Committee manage the Laboratory System Improvement Program (L-SIP). One component of L-SIP is an assessment that allows the members and stakeholders of a laboratory system to have an open and honest discussion about the laboratory system's strengths and weaknesses. From these facilitated discussions, gaps and opportunities for improvement are identified. In some cases, ideas for how to best address these gaps emerge, and workgroups are formed. Depending on resources, both monetary and personnel, laboratory staff will then prioritize the next component of L-SIP: which quality improvement activities to undertake. This article describes a sample of quality improvement activities initiated by several public health laboratories after they conducted L-SIP assessments. These projects can result in more robust linkages between system entities, which can translate into improvements in the way the system addresses the needs of stakeholders. PMID:23997301

Manufacturers of in vitro diagnostic (IVD) medical devices and laboratory management have become integral partners in building and improving the quality of laboratory services. There is an increasing awareness that quality is inherent in the design of any reagent or analytical system. In vitro diagnostic medical devices should provide patients, users and third parties with a high level of health protection. Therefore, both manufacturers and users must work in partnership for continual improvement. For manufacturers, standards such as ISO 9000 already exist to guide applications of quality practices. In the field of laboratory medicine, the availability of a specific, universal standard (ISO/DIS 15189) for quality management in medical laboratories will represent a great opportunity for harmonising medical laboratories at an international level. In addition, accreditation of medical laboratories according to the proposed ISO 15189 standard can help develop the relationships between laboratories, and the biological follow-up of travelling patients. Manufacturers are able to help laboratory management to reach a high level of quality, not only by providing high value products, but also on the basis of their own experience of ISO 9000 certification.

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.

Approaches to quality management and accreditation in a genetic testing laboratory  

PubMed Central

Medical laboratories, and specifically genetic testing laboratories, provide vital medical services to different clients: clinicians requesting a test, patients from whom the sample was collected, public health and medical-legal instances, referral laboratories and authoritative bodies. All expect results that are accurate and obtained in an efficient and effective manner, within a suitable time frame and at acceptable cost. There are different ways of achieving the end results, but compliance with International Organization for Standardization (ISO) 15189, the international standard for the accreditation of medical laboratories, is becoming progressively accepted as the optimal approach to assuring quality in medical testing. We present recommendations and strategies designed to aid genetic testing laboratories with the implementation of a quality management system, including key aspects such as document control, external quality assessment, internal quality control, internal audit, management review, validation, as well as managing the human side of change. The focus is on pragmatic approaches to attain the levels of quality management and quality assurance required for accreditation according to ISO 15189, within the context of genetic testing. Attention is also given to implementing efficient and effective quality improvement. PMID:20720559

[Quality control in clinical trials].  

PubMed

Quality control (QC) in clinical trials means the procedures which insure protection of human subjects from research risk, reliability of the data, and thereby assures internal consistency. This has been developed since 1970s in the US, by establishing various regulations which are now called GCP. From the viewpoint of total QC, it should be emphasized that rigorous review of protocol by the Institutional Review Board and obtaining Informed Consent are prerequisites for insuring the quality of the given trial at high scientific level. When pursuing a clinical trial, first of all, facilities of the institutions and the ability of investigators must be of high quality. For this reason, at each institution previous data related to trials should be thoroughly reviewed and analyzed prior to developing a protocol. Educational courses in QC in clinical practice are invaluable. QC of diagnosis means, for example, central pathology review and standardization of diagnostic procedures and process. Secondly, at each institution, data managers collect the data and submit them to the central office at the indicated time. In order to evolve clinical trial, continuous education for data managers and expansion of their job are encouraged. Thirdly, at the statistical center independent from the research group office, subject-specific data managers, the biostatistical staff, must check submitted forms for completeness, consistency and accuracy. Finally, at the data analysis, quality evaluation of the research should also be carried out. Throughout the trial, monitoring and audit are particularly important to assure quality. The sponsor has the responsibility of monitoring the trial and make rigorous onsite visits, and the individual study group also have a monitoring program, while the FDA and the NCI audit by themselves. The purpose of audit is not only to assure data reliability but also to check out patient compliance to drug, education as to regulations and rules of clinical trials and the analysis of violations so as to provide suggestions to improve medical care.

The quality control of drugs is generally made by HPLC. This control could be made also by capillary electrochromatography (CEC). In this paper we report the analysis by CEC of ibuprofen, a well-known anti-inflammatory non steroidic drug, and some of its impurities. The analyses were performed in a 100-microm inner diameter (I.D.) fused silica capillary, packed with RP-18 stationary phase. The mobile phase was a mixture of 100 mM formic acid solution (pH 2.5), water and acetonitrile (ACN). The ACN percentage in the mobile phase and the applied voltage were carefully studied to well resolve the drug from each impurity. The results, obtained determining ibuprofen and related compounds by CEC, showed the selectivity and efficiency of the method. PMID:13679163

Quality management in the medical laboratory: a comparison of draft standards.  

PubMed

Clinical laboratories used to rely almost completely on functional tests to monitor and assess their performance. This is known as internal quality control (IQC). A supporting approach is the interlaboratory comparison. In many countries and other disciplines this is known as proficiency testing, whereas, in Europe, the procedure is better known as external quality assessment taken care of by different schemes (EQAS). Probably all laboratories participate in some kind of EQAS and in some countries it is mandatory. It has gradually become apparent that functional tests are not sufficient to achieve, assure and develop quality in medical laboratories. Therefore other means must be sought. The principles laid down in the ISO 9000 series and the total quality concept has become interesting; in particular, accreditation. Accreditation of laboratories has been available for many years and in fact is routine in some specialities e.g. food, water laboratories and in some countries also for laboratories in the veterinary field. The present paper describes some features of the available and planned ISO standards that deal with accreditation of laboratories and particularly those adopted for the medical laboratories.

Implementation of Good Clinical Laboratory Practice (GCLP) guidelines within the External Quality Assurance Program Oversight Laboratory (EQAPOL).  

PubMed

The EQAPOL contract was awarded to Duke University to develop and manage global proficiency testing programs for flow cytometry-, ELISpot-, and Luminex bead-based assays (cytokine analytes), as well as create a genetically diverse panel of HIV-1 viral cultures to be made available to National Institutes of Health (NIH) researchers. As a part of this contract, EQAPOL was required to operate under Good Clinical Laboratory Practices (GCLP) that are traditionally used for laboratories conducting endpoint assays for human clinical trials. EQAPOL adapted these guidelines to the management of proficiency testing programs while simultaneously incorporating aspects of ISO/IEC 17043 which are specifically designed for external proficiency management. Over the first two years of the contract, the EQAPOL Oversight Laboratories received training, developed standard operating procedures and quality management practices, implemented strict quality control procedures for equipment, reagents, and documentation, and received audits from the EQAPOL Central Quality Assurance Unit. GCLP programs, such as EQAPOL, strengthen a laboratory's ability to perform critical assays and provide quality assessments of future potential vaccines. PMID:24120573

Quality Control by Artificial Vision  

SciTech Connect

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-basis functions for this task. Image registration is another important task for machine vision. Bingham and Arrowood investigate the implementation and results in applying Fourier phase matching for projection registration, with a particular focus on nondestructive testing using computed tomography. Readers interested in enriching their arsenal of image-processing algorithms for machine-vision tasks should find these papers enriching. Meanwhile, we have four papers dealing with more specific machine-vision tasks. The first one, Yahiaoui et al., is quantitative in nature, using machine vision for real-time passenger counting. Occulsion is a common problem in counting objects and people, and they circumvent this issue with a dense stereovision system, achieving 97 to 99% accuracy in their tests. On the other hand, the second paper by Oswald-Tranta et al. focuses on thermographic crack detection. An infrared camera is used to detect inhomogeneities, which may indicate surface cracks. They describe the various steps in developing fully automated testing equipment aimed at a high throughput. Another paper describing an inspection system is Molleda et al., which handles flatness inspection of rolled products. They employ optical-laser triangulation and 3-D surface reconstruction for this task, showing how these can be achieved in real time. Last but not least, Presles et al. propose a way to monitor the particle-size distribution of batch crystallization processes. This is achieved through a new in situ imaging probe and image-analysis methods. While it is unlikely any reader may be working on these four specific problems at the same time, we are confident that readers will find these papers inspiring and potentially helpful to their own machine-vision system developments.

[Compatibility of different quality control systems].  

PubMed

Management of the good laboratory practice (GLP) quality system presupposes its linking to a basic recognized and approved quality system, from which it can draw on management procedures common to all quality systems, such as the ISO 9000 set of norms. A quality system organized in this way can also be integrated with other dedicated quality systems, or parts of them, to obtain principles or management procedures for specific topics. The aim of this organization is to set up a reliable, recognized quality system compatible with the principles of GLP and other quality management systems, which provides users with a simplified set of easily accessible management tools and answers. The organization of this quality system is set out in the quality assurance programme, which is actually the document in which the test facility incorporates the GLP principles into its own quality organization.

On November 9, 2002, the U.S. Environmental Protection Agency (EPA), the U.S. Department of Energy (DOE), and the Idaho Department of Environmental Quality approved the Record of Decision Experimental Breeder Reactor-I/Boiling Water Reactor Experiment Area and Miscellaneous Sites, which requires a Sitewide Institutional Controls Plan for the then Idaho National Engineering and Environmental Laboratory (now known as the Idaho National Laboratory). This document, first issued in June 2004, fulfilled that requirement. The revision is needed to provide an update as remedial actions are completed and new areas of concern are found. This Sitewide Institutional Controls Plan is based on guidance in the May 3, 1999, EPA Region 10 Final Policy on the Use of Institutional Controls at Federal Facilities; the September 29, 2000, EPA guidance Institutional Controls: A Site Manager's Guide to Identifying, Evaluating, and Selecting Institutional Controls at Superfund and RCRA Corrective Action Cleanups; and the April 9, 2003, DOE Policy 454.1, "Use of Institutional Controls." These policies establish measures that ensure short- and long-term effectiveness of institutional controls that protect human health and the environment at federal facility sites undergoing remedial action pursuant to the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) and/or corrective action pursuant to the Resource Conservation and Recovery Act (RCRA). The site-specific institutional controls currently in place at the Idaho National Laboratory are documented in this Sitewide Institutional Controls Plan. This plan is being updated, along with the Idaho National Engineering and Environmental Laboratory Comprehensive Facilities and Land Use Plan, to reflect the progress of remedial activities and changes in CERCLA sites.

Gradient algorithm applied to laboratory quantum control  

SciTech Connect

The exploration of a quantum control landscape, which is the physical observable as a function of the control variables, is fundamental for understanding the ability to perform observable optimization in the laboratory. For high control variable dimensions, trajectory-based methods provide a means for performing such systematic explorations by exploiting the measured gradient of the observable with respect to the control variables. This paper presents a practical, robust, easily implemented statistical method for obtaining the gradient on a general quantum control landscape in the presence of noise. In order to demonstrate the method's utility, the experimentally measured gradient is utilized as input in steepest-ascent trajectories on the landscapes of three model quantum control problems: spectrally filtered and integrated second harmonic generation as well as excitation of atomic rubidium. The gradient algorithm achieves efficiency gains of up to approximately three times that of the standard genetic algorithm and, as such, is a promising tool for meeting quantum control optimization goals as well as landscape analyses. The landscape trajectories directed by the gradient should aid in the continued investigation and understanding of controlled quantum phenomena.

[Implementation of the technical requirements of the UNE-EN-ISO 15189 quality standard in a mycobacterial laboratory].  

PubMed

The UNE-EN-ISO 15189:2007 standard defines the requirements for quality and competence that must be met by medical laboratories. These laboratories should use this international standard to develop their own quality management systems and to evaluate their own competencies; in turn, this standard will be used by accreditation bodies to confirm or recognize the laboratories' competence. In clinical microbiology laboratories, application of the standard implies the implementation of the technical and specific management requirements that must be met to achieve optimal quality when carrying out microbiological tests. In Spain, accreditation is granted by the Spanish Accreditation Body (Entidad Nacional de Acreditación). This review aims to discuss the practical application of the standard's technical requirements in mycobacterial laboratory. Firstly, we define the scope of accreditation. Secondly, we specify how the items of the standard on personnel management, control of equipment, environmental facilities, method validation, internal controls and customer satisfaction surveys were developed and implemented in our laboratory.

Tracking and controlling everything that affects quality is the key to a quality management system.  

PubMed

Every laboratory has a need to track and control the variables that drive the quality of the results. However, each laboratory is unique and what one organization deems to be a critical process to track and control will likely differ from other organizations. Furthermore, there is more than just the end product or result that needs to be tracked and controlled. All of the intermediate products and resources play a significant role in producing the final product and each of these needs to be included in the LIMS. At a high level, this article will present ideas and opinions on the following topics in relation to implementing a LIMS process tracking and control system in a laboratory: The difference between tracking and controlling processes; What to track and control in the lab; The "product" of the laboratory; Preventing mistakes in a laboratory; Comprehensive software platform options; The value of seeing a system as opposed to imagining it; The use of barcodes in the laboratory; and an assessment on using the Risk Based Approach in deciding what to include in the tracking system.

Quality assurance and quality control in diagnostic molecular biology.  

PubMed

The newest forms of clinical diagnostic testing are based upon tools gleaned from molecular biology. Manipulations of RNA and DNA from various tissue sources (e.g., skin, blood, urine, excised tumor) can provide valuable information about an individual's genetic status or the basis or potential for metastasis of a tumor. As of 2002, over 200 laboratories in the United States provide clinical services. Particularly when such information is to be used to provide genetic counseling or determine treatment, care must be taken to ensure accuracy in the generation and reporting of results. This unit outlines the aspects of quality assurance that are important in nucleic acid-based diagnostic testing. More specifically, it describes the three elements of a quality assurance program: the directors qualifications, on-site laboratory inspection, and interlaboratory comparison and proficiency testing. The unit also discusses how to evaluate if a particular genetic test is suitable for clinical testing. PMID:18428335

Control by quality: proposition of a typology.  

PubMed

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 operators. Strategic control by quality is then detailed, and the two main approaches, the continuous improvement approach and the proactive improvement approach, are introduced. Finally, the authors observe that at each of the three levels, the continuous process improvement, which is a component of Total Quality, becomes an essential preoccupation for the control. Ultimately, the recursive utilization of the Deming cycle remains the best practice for the control by quality. PMID:12512551

Control of Spacecraft Control Laboratory Experiment (SCOLE) slew maneuvers  

NASA Technical Reports Server (NTRS)

This is the second report of a set of two reports on the dynamics and control of slewing maneuvers of NASA Spacecraft Control Laboratory Experiment (SCOLE). The control problem of slewing maneuvers of SCOLE is developed in terms of an arbitrary maneuver about any given axis. The control system is developed for the combined problem of rigid-body slew maneuver and vibration suppression of flexible appendage. The control problem is formulated by incorporating the nonlinear equations derived in the previous report and is expressed in terms of a two-point boundary value problem utilizing a quadratic type of performance index. The two-point boundary value problem is solved as a hierarchical control problem with the overall system being split in terms of two subsystems, namely the slewing of the entire assembly and the vibration suppression of the flexible antenna. The coupling variables between the two dynamical subsystems are identified and these two subsystems for control purposes are treated independently in parallel at the first level. Then the state-space trajectory of the combined problem is optimized at the second level.

Novel methodology to assess sputum smear microscopy quality in private laboratories  

PubMed Central

Background In South Asia, it is estimated that 80% of patients choose to attend a private facility for their healthcare needs. Although patients generally believe that the private-sector provides high quality services, private diagnostic laboratories are largely unregulated and little is known about the accuracy of results provided. This study assesses the accuracy of sputum smear microscopy for pulmonary tuberculosis diagnosis in private laboratories operating in Karachi, Pakistan. A novel evaluation methodology was designed in which patient-actors submitted sputum specimens spiked with cultured Mycobacterium tuberculosis (Mtb) for testing such that laboratories were not aware that they were being assessed. Methods Smear-negative sputum specimens from Indus Hospital TB Program patients were collected and combined with an attenuated, cultured Mtb strain to create Mtb-spiked samples; for negative standards, no Mtb was added to the smear-negative sputum specimens. Seven of the largest private laboratories across Karachi were chosen for evaluation and were sent six Mtb-spiked and one Mtb-negative sputum specimens. Patient-actors pretending to be laboratory customers submitted these specimens to each laboratory for testing over a three day period. Results Only three laboratories accurately classified all the Mtb-spiked specimens which were submitted. A further three misclassified all the Mtb-spiked specimens as smear-negative, thus providing the ‘patients’ with false negative results. Conclusions TB sputum smear microscopy services are highly variable across private laboratories and are often of extremely poor quality. Engagement, capacity building and rigorous monitoring of standards at private laboratories are of vital importance for the control of TB. Our findings, while specific for TB diagnostic tests, could be symptomatic of other tests performed in private laboratories and warrant further investigation. PMID:23193964

The Agilent 2200 TapeStation system provides a flexible solution for automated analysis of up to 96 samples using pre-packaged reagents and minimal manual handling. Here we present a new assay – the RNA ScreenTape assay – to enable robust quantification and quality analysis of Total RNA samples from both eukaryotic and prokaryotic sources from 100 pg/?l to 500 ng/?l. The new assay additionally benefits from the ability to provide separation of contaminant genomic DNA allowing more accurate purity assessment of sample material. This study compares the performance of the new RNA assays against the market leading Agilent 2100 Bioanalyzer and NanoDrop for RNA quality and quantity determination. We conclude that the new RNA ScreenTape and High Sensitivity assays provide correlated data to these existing technologies, as well as exceeding these technologies in terms of flexibility and automation.

Controller Design of Power Quality-Improving Appliances  

SciTech Connect

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.

Quality control in the endoplasmic reticulum  

Microsoft Academic Search

The endoplasmic reticulum (ER) has a quality-control system for 'proof-reading' newly synthesized proteins, so that only native conformers reach their final destinations. Non-native conformers and incompletely assembled oligomers are retained, and, if misfolded persistently, they are degraded. As a large fraction of ER-synthesized proteins fail to fold and mature properly, ER quality control is important for the fidelity of cellular

Quality assurance plan for Waste Area Grouping 6 at Oak Ridge National Laboratory, Oak Ridge, Tennessee  

SciTech Connect

This Quality Assurance Plan (QAP) is concerned with design and construction (Sect. 2) and characterization and monitoring (Sect. 3). The basis for Sect. 2 is the Quality Assurance Plan for the Design and Construction of Waste Area Grouping 6 Closure at Oak Ridge National Laboratory, Oak Ridge, Tennessee, and the basis for Sect. 3 is the Environmental Restoration Quality Program Plan. Combining the two areas into one plan gives a single, overall document that explains the requirements and from which the individual QAPs and quality assurance project plans can be written. The Waste Area Grouping (WAG) 6 QAP establishes the procedures and requirements to be implemented for control of quality-related activities for the WAG 6 project. Quality Assurance (QA) activities are subject to requirements detailed in the Martin Marietta Energy Systems, Inc. (Energy Systems), QA Program and the Environmental Restoration (ER) QA Program, as well as to other quality requirements. These activities may be performed by Energy Systems organizations, subcontractors to Energy Systems, and architect-engineer (A-E) under prime contract to the US Department of Energy (DOE), or a construction manager under prime contract to DOE. This plan specifies the overall Energy Systems quality requirements for the project. The WAG 6 QAP will be supplemented by subproject QAPs that will identify additional requirements pertaining to each subproject.

Does laboratory automation for the preanalytical phase improve data quality?  

PubMed

Our aim was to evaluate whether automation for the preanalytical phase improves data quality. Blood from 100 volunteers was collected into two vacuum tubes. One sample from each volunteer was respectively assigned to (G1) traditional processing, starting with centrifugation at 1200 g for 10 min, and (G2) the MODULAR PRE-ANALYTICALS EVO-MPA system. The routine clinical chemistry tests were performed in duplicate on the same instrument Cobas 6000 module. G1 samples were uncapped manually and immediately placed into the instrument. G2 samples were directly fed from the MPA system to the instrument without further staff intervention. At the end, (1) the G1 samples were stored for 6 h at 4 °C as prescribed in our accredited laboratory and (2) the G2 samples were stored for 6 h in the MPA output buffer. Results from G1 and G2, before and after storage, were compared. Significant increases were observed in G1 compared with G2 samples as follows: (1) before storage for alkaline phosphatase (ALP), lactate dehydrogenase (LDH), phosphate (P), magnesium (MG), iron (FE), and hemolysis index and (2) after storage for total cholesterol (COL), triglycerides (TG), total protein (TP), albumin (ALB), blood urea nitrogen (BUN), creatinine (CRE), uric acid (UA), ALP, pancreatic amylase, aspartate aminotransferase (AST), alanine aminotransferase (ALT), g-glutamyltransferase (GGT), LDH, creatine kinase (CK), calcium (CA), FE, sodium (NA), potassium (K), and hemolysis index. Moreover, significant increases were observed in (3) G1-after versus G1-before storage samples for COL, high-density lipoprotein cholesterol, TG, TP, ALB, BUN, CRE, UA, AST, ALT, GGT, LDH, P, CA, MG, FE, NA, K, and hemolysis index and (4) G2-after versus G2-before storage only for BUN, AST, LDH, P, and CA. In conclusion, our results show that the MPA system improves the quality of laboratory testing. PMID:23686657

Quality Control of "DLG and MAP" Product  

NASA Astrophysics Data System (ADS)

The product of "DLGM" is a vector dataset of DLG and map, and is software independent, which is produced by our DLGM integrated technology system. This product has been included in the fundamental Geographic Information system (GIS), and confirmed by the mapping industry with its advantages of the integration, commonality, and multi-purpose. As a new kind product of digital map, it involves a large number of theoretical issues and technical problems. Specially, quality of product is a crucial problem in one of them. In our study, the basic framework of DLGM product is given firstly. And then we talk about quality control method and mechanisms in the production process, which involved dynamic modelling based on the topological map model, data dictionary and "DLG and Map" integration template. The core task of this process is the consistency of maps and its corresponding geographic information. The rule of the process ensures the data quality in aspects of products design, manufacturing process method, tools, quality testing, application and data exchange. In recent years of practical application, a number of provincial fundamental DLGM products were produced by our DLGM integrated technology system, which has passed the existing quality standard authentication. It proved factually that the product quality control theory and technology which is adopted in our system is effective and feasible. At present, the technology and quality control method has been playing an important role in DLGM products.

Post-translational Modification and Quality Control  

PubMed Central

Protein quality control (PQC) functions to minimize the level and toxicity of misfolded proteins in the cell. PQC is performed by intricate collaboration among chaperones and target protein degradation. The latter is carried out 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 (e.g., mitochondria) and targeting them for degradation by the lysosome. Inadequate PQC is observed in a large subset of failing human hearts with a variety of etiologies and its pathogenic role has been experimentally demonstrated. Multiple post-translational modifications (PTMs) can occur to substrate proteins and/or PQC machineries, promoting or hindering the removal of the misfolded proteins. This article highlights recent advances in PTMs-mediated regulation of intracellular quality control mechanisms and its known involvement in cardiac pathology. PMID:23329792

Quality control technique to reduce the variability of longitudinal measurement of hemoglobin mass.  

PubMed

The sensitivity of the athlete blood passport to detect blood doping may be improved by the inclusion of total hemoglobin mass (Hb(mass)), but the comparability of Hb(mass) from different laboratories is unknown. To optimize detection sensitivity, the analytical variability associated with Hb(mass) measurement must be minimized. The aim of this study was to investigate the efficacy of using quality controls to minimize the variation in Hb(mass) between laboratories. Three simulated laboratories were set up in one location. Nine participants completed three carbon monoxide (CO) re-breathing tests in each laboratory. One participant completed two CO re-breathing tests in each laboratory. Simultaneously, quality controls containing Low (1-3%) and High (8-11%) concentrations of percent carboxyhemoglobin (%HbCO) were measured to compare hemoximeters in each laboratory. Linear mixed modeling was used to estimate the within-subject variation in Hb(mass), expressed as the coefficient of variation, and to estimate the effect of different laboratories. The analytic variation of Hb(mass) was 2.4% when tests were conducted in different laboratories, which reduced to 1.6% when the model accounted for between-laboratory differences. Adjustment of Hb(mass) values using quality controls achieved a comparable analytic variation of 1.7%. The majority of between-laboratory variation in Hb(mass) originated from the difference between hemoximeters, which could be eliminated using appropriate quality controls. PMID:21535184

Quality control algorithms for rainfall measurements  

NASA Astrophysics Data System (ADS)

One of the basic requirements for a scientific use of rain data from raingauges, ground and space radars is data quality control. Rain data could be used more intensively in many fields of activity (meteorology, hydrology, etc.), if the achievable data quality could be improved. This depends on the available data quality delivered by the measuring devices and the data quality enhancement procedures. To get an overview of the existing algorithms a literature review and literature pool have been produced. The diverse algorithms have been evaluated to meet VOLTAIRE objectives and sorted in different groups. To test the chosen algorithms an algorithm pool has been established, where the software is collected. A large part of this work presented here is implemented in the scope of the EU-project VOLTAIRE ( Validati on of mu ltisensors precipit ation fields and numerical modeling in Mediter ran ean test sites).

A laboratory study on groundwater quality and mass movement occurrence  

NASA Astrophysics Data System (ADS)

In this study, soil samples collected from the sides of two streams with high debris flow potential at Shenmu and Fengchiou village in Nantou County, Taiwan, were used for seepage tank tests in the laboratory. While the tests were being conducted, observations were made to investigate the relationships among displacement of the slope, quality of the seepage water and occurrence of mass movement. The results showed that according to the change rate, displacement could be divided into two stages, namely, the initial failure displacement stage and primary failure displacement stage. While the displacement of the slope was in primary failure displacement stages, the probability of slope failure became much higher. Before general slope failure, electrical conductivity (EC) and sulfate ion (SO4 2-) concentration of the seepage water increased significantly. The time when EC of the seepage water started to increase rapidly was much earlier than that when displacement of the slope started to increase significantly. Therefore, from the hazard mitigation view, there will be a longer time for response if EC of the seepage water was monitored.

Statistical quality control through overall vibration analysis  

NASA Astrophysics Data System (ADS)

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 of predictive variables (high-frequency vibration displacements) that are sensible to the processes setup and the quality of the products obtained. Based on the result of this overall vibration analysis, a second paper will analyse self-induced vibration spectrums in order to define limit vibration bands, controllable every cycle or connected to permanent vibration-monitoring systems able to adjust sensible process variables identified by ANOVA, once the vibration readings exceed established quality limits.

Quality and Control of Water Vapor Winds  

NASA Technical Reports Server (NTRS)

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 modifications. The improvement in winds through use of these new quality and control parameters is measured without the use of rawinsonde or modeled wind field data and compared with other approaches.

Remote Quality Control Integrated with Internet-Based Robotic Systems  

NSDL National Science Digital Library

The current trends in industry include an integration of information and knowledge base network with a manufacturing system, which coined a new term, e-manufacturing. From the perspective of e-manufacturing, any production equipment and its control functions do not exist alone, instead becoming a part of the holistic operation system with distant monitoring, remote quality control and fault diagnostic capabilities. The key to this new paradigm is the accessibility to a remotely located system and having the means of responding to a rapidly changing environment. In this context, this paper presents innovative methods in remote part tracking and quality control using the Ethernet Smart Image Sensor and the Internet controllable Yamaha SCARA robot. The accuracy of the proposed scheme has been verified and subsequent quality control functions have been integrated, which vindicate the industrial applicability of the setup. The paper also discusses some of the online experiments conducted by the students and presents the evaluation outcomes. The experiment results suggest that online laboratory learning can be substantially enhanced by the use of even the simplest form of artificial graphical information and most students prefer having an instructor present even though the lab is taught online. The implications from this study can be used to benefit many schools that begun offering online lab courses.

Quality assurance practices in Europe: a survey of molecular genetic testing laboratories  

PubMed Central

In the 2000s, a number of initiatives were taken internationally to improve quality in genetic testing services. To contribute to and update the limited literature available related to this topic, we surveyed 910 human molecular genetic testing laboratories, of which 291 (32%) from 29 European countries responded. The majority of laboratories were in the public sector (81%), affiliated with a university hospital (60%). Only a minority of laboratories was accredited (23%), and 26% was certified. A total of 22% of laboratories did not participate in external quality assessment (EQA) and 28% did not use reference materials (RMs). The main motivations given for accreditation were to improve laboratory profile (85%) and national recognition (84%). Nearly all respondents (95%) would prefer working in an accredited laboratory. In accredited laboratories, participation in EQA (P<0.0001), use of RMs (P=0.0014) and availability of continuous education (CE) on medical/scientific subjects (P=0.023), specific tasks (P=0.0018), and quality assurance (P<0.0001) were significantly higher than in non-accredited laboratories. Non-accredited laboratories expect higher restriction of development of new techniques (P=0.023) and improvement of work satisfaction (P=0.0002) than accredited laboratories. By using a quality implementation score (QIS), we showed that accredited laboratories (average score 92) comply better than certified laboratories (average score 69, P<0.001), and certified laboratories better than other laboratories (average score 44, P<0.001), with regard to the implementation of quality indicators. We conclude that quality practices vary widely in European genetic testing laboratories. This leads to a potentially dangerous situation in which the quality of genetic testing is not consistently assured. PMID:22739339

Quality control and analytical techniques for biopharmaceuticals.  

PubMed

Biopharmaceuticals are complex products and to ensure their batch-to-batch consistency and continuing quality the use of a combination of complementary analytical tests is required. Regulatory guidelines indicate quality attributes of different product classes to be included in the specifications for product release. Whilst the continuing development of sophisticated physicochemical techniques make them increasingly powerful for defining product identity, integrity, purity and the consistency of the manufacturing process, the results generated are not easily related to the biological activity. Consequently, a bioassay is normally required in the quality control to determine the potency, that is, the quantitative measure of the product's ability to cause a specific biological effect in a defined biological system. A wide, and rapidly increasing, range of bioassay systems exist, each type with particular advantages and disadvantages. PMID:21175369

Repeated HIV-1 resistance genotyping external quality assessments improve virology laboratory performance.  

PubMed

The performance of French virology laboratories belonging to the ANRS network has been assessed annually for 3 years. The performance of these laboratories was compared between the years 2002 and 2003. Ten and 7 coded samples were sent to 38 virology laboratories in 2002 and 45 virology laboratories in 2003, respectively. Each panel of coded samples included at least one HIV-negative control, a pair of duplicate specimens, samples with a wide range of viral loads, and samples with a large number of resistance mutations. The laboratories used their standard sequencing procedures and were asked to report the amino acids at codons associated with resistance mutations, based on the IAS-USA expert panel list. The reference amino acid sequences were defined as those most frequently reported by the participants. The specificity of detection of RT mutations was significantly better in 2003 (99.9%) than in 2002 (99.7%) (P = 0.05). There was no difference between 2002 and 2003 in the specificity of detection of protease mutations (99.6% and 99.8%) or the sensitivity of detection of RT mutations (98.8% and 98.2%). The sensitivity of detection of protease mutations improved significantly between 2002 and 2003 (97.6% and 99.0%, respectively; P = 0.037). The proportion of laboratories reporting fully accurate results, in terms of amplification, specificity, sensitivity, and reproducibility, tended to increase between 2002 and 2003 (P = 0.077). No errors were made by 19% of laboratories in 2002, compared to 42% in 2003. These results show the value of repeated external quality assessments. PMID:16372300

Field methods and quality-assurance plan for water-quality activities and water-level measurements, U.S. Geological Survey, Idaho National Laboratory, Idaho  

USGS Publications Warehouse

Water-quality activities and water-level measurements by the personnel of the U.S. Geological Survey (USGS) Idaho National Laboratory (INL) Project Office coincide with the USGS mission of appraising the quantity and quality of the Nation’s water resources. The activities are carried out in cooperation with the U.S. Department of Energy (DOE) Idaho Operations Office. Results of the water-quality and hydraulic head investigations are presented in various USGS publications or in refereed scientific journals and the data are stored in the National Water Information System (NWIS) database. The results of the studies are used by researchers, regulatory and managerial agencies, and interested civic groups. In the broadest sense, quality assurance refers to doing the job right the first time. It includes the functions of planning for products, review and acceptance of the products, and an audit designed to evaluate the system that produces the products. Quality control and quality assurance differ in that quality control ensures that things are done correctly given the “state-of-the-art” technology, and quality assurance ensures that quality control is maintained within specified limits.

A Power Control Scheme between Quality Control Centers in FRIENDS  

NASA Astrophysics Data System (ADS)

FRIENDS(Flexible, Reliable, and Intelligent Electrical eNergy Delivery System)is proposed as a new concept for a future power distribution system. One of the most important characteristics of FRIENDS is that QCC(Quality Control Center)as a new power quality control facility is installed very closely to customers. As one of the congurations of QCCs, AC-type QCC in which several Distributed Generators (DGs) can be installed easily has been proposed by authors. In FRIENDS concept, power exchange control between QCCs is included in fault case in upstream power system for higher reliability and making good use of power of distributed generators. A method to control several QCCs in fault case is proposed, and simulation results are shown in this paper.

Quality Control Mechanisms During Ribosome Maturation  

PubMed Central

Protein synthesis on ribosomes is carefully quality controlled to ensure the faithful transmission of genetic information from mRNA to protein. Many of these mechanisms rely on communication between distant sites on the ribosomes, and thus on the integrity of the ribosome structure. Furthermore, haploinsufficiency of ribosomal proteins, which increases the chances of forming incompletely assembled ribosomes, can predispose to cancer. Finally, release of inactive ribosomes into the translating pool will lead to their degradation together with the degradation of the bound mRNA. Together, these findings suggest that quality control mechanisms must be in place to survey nascent ribosomes and ensure their functionality. This review gives an account of these mechanisms as currently known. PMID:23375955

Quality-Assurance/Quality-Control Manual for Collection and Analysis of Water-Quality Data in the Ohio District, US Geological Survey  

USGS Publications Warehouse

The U.S. Geological Survey (USGS), Water Resources Division (WRD), requires that quality-assurance/quality-control (QA/QC) activities be included in any sampling and analysis program. Operational QA/QC procedures address local needs while incorporating national policies. Therefore, specific technical policies were established for all activities associated with water-quality project being done by the Ohio District. The policies described in this report provide Ohio District personnel, cooperating agencies, and others with a reference manual on QA/QC procedures that are followed in collecitng and analyzing water-quality samples and reporting water-quality information in the Ohio District. The project chief, project support staff, District Water-Quality Specialist, and District Laboratory Coordinator are all involved in planning and implementing QA/QC activities at the district level. The District Chief and other district-level managers provide oversight, and the Regional Water-Quality Specialist, Office of Water Quality (USGS headquarters), and the Branch of Quality Systems within the Office of Water Quality create national QA/QC polices and provide assistance to District personnel. In the literature, the quality of all measurement data is expressed in terms of precision, variability, bias, accuracy, completeness, representativeness, and comparability. In the Ohio District, bias and variability will be used to describe quality-control data generated from samples in the field and laboratory. Each project chief must plan for implementation and financing of QA/QC activities necessary to achieve data-quality objectives. At least 15 percent of the total project effort must be directed toward QA/QC activities. Of this total, 5-10 percent will be used for collection and analysis of quality-control samples. This is an absolute minimum, and more may be required based on project objectives. Proper techniques must be followed in the collection and processing of surface-water, ground-water, biological, precipitation, bed-sediment, bedload, suspended-sediment, and solid-phase samples. These techniques are briefly described in this report and are extensively documented. The reference documents listed in this report will be kept by the District librarian and District Water-Quality Specialist and updated regularly so that they are available to all District staff. Proper handling and documentation before, during, and after field activities are essential to ensure the integrity of the sample and to correct erroneous reporting of data results. Field sites are to be properly identified and entered into the data base before field data-collection activities begin. During field activities, field notes are to be completed and sample bottles appropriately labeled a nd stored. After field activities, all paperwork is to be completed promptly and samples transferred to the laboratory within allowable holding times. All equipment used by District personnel for the collection and processing of water-quality samples is to be properly operated, maintained, and calibrated by project personnel. This includes equipment for onsite measurement of water-quality characteristics (temperature, specific conductance, pH, dissolved oxygen, alkalinity, acidity, and turbidity) and equipment and instruments used for biological sampling. The District Water-Quality Specialist and District Laboratory Coordinator are responsible for preventive maintenance and calibration of equipment in the Ohio District laboratory. The USGS National Water Quality Laboratory in Arvada, Colo., is the primary source of analytical services for most project work done by the Ohio District. Analyses done at the Ohio District laboratory are usually those that must be completed within a few hours of sample collection. Contract laboratories or other USGS laboratories are sometimes used instead of the NWQL or the Ohio District laboratory. When a contract laboratory is used, the projec

Protein Quality Control in the Nucleus  

PubMed Central

In their natural environment, cells are regularly exposed to various stress conditions that may lead to protein misfolding, but also in the absence of stress, misfolded proteins occur as the result of mutations or failures during protein synthesis. Since such partially denatured proteins are prone to aggregate, cells have evolved several elaborate quality control systems to deal with these potentially toxic proteins. First, various molecular chaperones will seize the misfolded protein and either attempt to refold the protein or target it for degradation via the ubiquitin-proteasome system. The degradation of misfolded proteins is clearly compartmentalized, so unique degradation pathways exist for misfolded proteins depending on whether their subcellular localization is ER/secretory, mitochondrial, cytosolic or nuclear. Recent studies, mainly in yeast, have shown that the nucleus appears to be particularly active in protein quality control. Thus, specific ubiquitin-protein ligases located in the nucleus, target not only misfolded nuclear proteins, but also various misfolded cytosolic proteins which are transported to the nucleus prior to their degradation. In comparison, much less is known about these mechanisms in mammalian cells. Here we highlight recent advances in our understanding of nuclear protein quality control, in particular regarding substrate recognition and proteasomal degradation. PMID:25010148

Antimicrobial susceptibility testing of Streptococcus pneumoniae and Haemophilus influenzae --internal quality control as a quality tool on a national level.  

PubMed

Knowledge of the quality and conformity of antimicrobial resistance data is important for comparing resistance rates regionally and over time. In this study, we have evaluated these features of the Finnish national susceptibility surveillance data for two respiratory tract pathogens, Streptococcus pneumoniae and Haemophilus influenzae. For this purpose internal quality control results for two isolates (S. pneumoniae ATCC 49619 and H. influenzae ATCC 49247) were analyzed from 21 clinical microbiology laboratories over a 3-year period. The results show that standardization of the susceptibility testing methods has proceeded well. The number of protocols used for susceptibility testing has declined (from seventeen methods to two with S. pneumoniae and from eleven to three with H. influenzae) and the reproducibility is good. Nevertheless, we noticed that a few laboratories test and report susceptibility results without defined break-points and even include antimicrobials with questionable therapeutic effect. Another non-compliance with the standard was a lack of a regular control system to verify the attainment of the intended quality of results in some laboratories. Interlaboratory analysis of quality control results is a good way to evaluate the quality and conformity of national resistance data. Finnish laboratories have produced very reproducible and accurate susceptibility results in the pre-EUCAST period, which ended in 2011. PMID:23163534

Weight control and restraint of laboratory rats  

NASA Technical Reports Server (NTRS)

The use of restrained and confined rats in some procedures used in combustion toxicology introduces the problems of obtaining rats of the appropriate size for the apparatus, and of identifying any artifacts resulting from the use of restraint alone. Feeding studies indicate that controlled feeding of fast-growing strains such as the Sprague-Dawley can hold rat size essentially constant for significant periods of time. The undesirable aspects are the need to cage the animals individually, with resultant psychological as well as metabolic effects. Restraint studies of slow-growing strains such as the Fischer 344 indicate that denying access to food and water for periods of several hours at a time interrupts normal gain only temporarily.

Statistical process control for radiotherapy quality assurance  

SciTech Connect

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.

Application of the Environmental Protection Agency`s data quality objective process to environmental monitoring quality control  

SciTech Connect

The United States Environmental Protection Agency`s (EPA) Data Quality Objectives (DQO) process was applied to two environmental monitoring networks for the purpose of optimizing field quality control sampling to give the highest quality monitoring data with minimal impact on resources. The DQO process, developed primarily to aid in cleanup and restoration activities, is a systematic approach to designing sampling, and analysis programs with improved efficiency, cost savings, and measureable and traceable data quality. The two monitoring- networks studied had not been subjected to the systematic review and analysis of the DQO process defined by the EPA. The two monitoring networks studied had relied upon field duplicates or replicates as the main source of field quality control data. Sometimes, both duplicate and routine sample were analyzed by the same analytical laboratory; at other times they were analyzed by different laboratories. This study identified some potential inconsistencies between analytical data and reporting limits from two different laboratories. Application of the EPA DQO process resulted in recommendations for changes in the field quality control sampling program, allowed new insight into the monitoring data, and raised several issues that should be the subject of further investigation.

Occupational therapy leaders have emphasized the importance of intervention effectiveness research. The CONSORT and TREND checklists have been suggested as useful tools for reporting the results of randomized and nonrandomized studies, respectively. Despite such recommendations, research protocols and reports continue to underutilize the available tools, a situation reflecting limited resources for and experience with the conduct of effectiveness research. To address this issue, and using the CONSORT statement to structure the analysis, this article discusses strategies for optimization of protocol development, treatment fidelity, adherence to treatment, and quality control. We recommend several approaches to increase the quality of research throughout these various processes. Examples of implementation from our laboratory provide evidence of the utility of these strategies. PMID:23433268

Effects of reorganization on laboratory quality: preliminary findings and lessons learned.  

PubMed

Reorganization and downsizing are common challenges for managers. This case study describes the implementation of a major restructuring of a clinical laboratory within a large, integrated medical-delivery organization. Economic trends prompted us to evaluate the effects of a major laboratory reorganization, with a significant shift from clinical laboratory scientists to lower waged, nonlicensed technical staff, on the analytic quality and other indicators of laboratory performance. Although a laboratory reorganization may be implemented slowly, this reorganization effort was completed quickly. Data were collected during both the pre- and post-reorganization period. Postimplementation performance indicators show no reductions in analytic quality. Effectively dealing with the human side of significant change appears to be the biggest challenge for managers, both in the short term and well after the reorganization. These results and qualitative information and insights might be of value to laboratory management contemplating a laboratory reorganization. PMID:12298436

A controllable laboratory stock market for modeling real stock markets  

NASA Astrophysics Data System (ADS)

Based on the different research approaches, econophysics can be divided into three directions: empirical econophysics, computational econophysics, and experimental econophysics. Because empirical econophysics lacks controllability that is needed to study the impacts of different external conditions and computational econophysics has to adopt artificial decision-making processes that are often deviated from those of real humans, experimental econophysics tends to overcome these problems by offering controllability and using real humans in laboratory experiments. However, to our knowledge, the existing laboratory experiments have not convincingly reappeared the stylized facts (say, scaling) that have been revealed for real economic/financial markets by econophysicists. A most important reason is that in these experiments, discrete trading time makes these laboratory markets deviated from real markets where trading time is naturally continuous. Here we attempt to overcome this problem by designing a continuous double-auction stock-trading market and conducting several human experiments in laboratory. As an initial work, the present artificial financial market can reproduce some stylized facts related to clustering and scaling. Also, it predicts some other scaling in human behavior dynamics that is hard to achieve in real markets due to the difficulty in getting the data. Thus, it becomes possible to study real stock markets by conducting controlled experiments on such laboratory stock markets producing high frequency data.

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

USGS Publications Warehouse

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 interpreting results. This primer has been developed to provide basic information and guidance about developing QA/QC protocols for geochemical studies. It is not intended to be a comprehensive guide but rather an introduction to key concepts tied to a list of relevant references for further reading. The guidelines are presented in stepwise order beginning with presampling considerations and continuing through final data interpretation. The goal of this primer is to outline basic QA/QC practices that scientists can use before, during, and after chemical analysis to ensure the validity of the data they collect with the goal of providing defendable results and conclusions.

Tools for quality control of fingerprint databases  

NASA Astrophysics Data System (ADS)

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.

Quality control of ATLAS muon chambers  

E-print Network

ATLAS is a general-purpose experiment for the future Large Hadron Collider (LHC) at CERN. Its Muon Spectrometer will require ? 5500m2 of precision tracking chambers to measure the muon tracks along a spectrometer arm of 5m to 15m length, embedded in a magnetic field of ? 0.5T. The precision tracking devices in the Muon System will be high pressure drift tubes (MDTs). Approximately 370,000 MDTs will be assembled into ? 1200 drift chambers. The performance of the MDT chambers is very much dependent on the mechanical quality of the chambers. The uniformity and stability of the performance can only be assured providing very high quality control during production. Gas tightness, high-voltage behaviour and dark currents are global parameters which are common to gas detectors. For all chambers, they will be tested immediately after the chamber assembly at every production site. Functional tests, for example radioactive source scans and cosmic-ray runs, will be performed in order to establish detailed performan...

quality control in steroid hormone receptor analyses.  

PubMed

In this paper, standards for steroid hormone receptor determinations in cancer tissue have been outlined. Standardization of methods for receptor extraction and receptor assay are equally important; and it is a condition sine qua non, if comparable receptor values between different centers for multilocal studies are required. Immediate and proper cooling of the tissue samples after removal, homogenization at the temperatures of the liquid nitrogen (as well as the presence of a sulfhydryl-protecting agent in the extraction medium), and the use of a simple, reproducible assay procedure are most important. As a standard procedure for ER- and PR-assays, the charcoal adsorption method combined with a scatchard-plot has been suggested. Reference procedures, like protein with DNA-assays, must also be standardized. Quality control experiments can be performed with lyophylized calf uterus homogenates. Additional determination of the nuclear estradiol in the high-speed sediments by radioimmunoassay is highly recommended. PMID:7448743

Quality Control for RNA-Seq (QuaCRS): An Integrated Quality Control Pipeline  

PubMed Central

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/. PMID:25368506

Entry Attitude Controller for the Mars Science Laboratory  

NASA Technical Reports Server (NTRS)

This paper describes the preliminary concept for the RCS 3-axis attitude controller for the exo-atmospheric and guided entry phases of the Mars Science Laboratory Entry, Descend and Landing. The entry controller is formulated as three independent channels in the control frame, which is nominally aligned with the stability frame. Each channel has a feedfoward and a feedback. The feedforward path enables fast response to large bank commands. The feedback path stabilizes the vehicle angle of attack and sideslip around its trim position, and tracks bank commands. The feedback path has a PD/D structure with deadbands that minimizes fuel usage. The performance of this design is demonstrated via simulation.

External Quality Assessment Scheme for reference laboratories - review of 8 years' experience.  

PubMed

We describe an External Quality Assessment Scheme (EQAS) intended for reference (calibration) laboratories in laboratory medicine and supervised by the Scientific Division of the International Federation of Clinical Chemistry and Laboratory Medicine and the responsible Committee on Traceability in Laboratory Medicine. The official EQAS website, RELA (www.dgkl-rfb.de:81), is open to interested parties. Information on all requirements for participation and results of surveys are published annually. As an additional feature, the identity of every participant in relation to the respective results is disclosed. The results of various groups of measurands (metabolites and substrates, enzymes, electrolytes, glycated hemoglobins, proteins, hormones, thyroid hormones, therapeutic drugs) are discussed in detail. The RELA system supports reference measurement laboratories preparing for accreditation according to ISO 17025 and ISO 15195. Participation in a scheme such as RELA is one of the requirements for listing of the services of a calibration laboratory by the Joint Committee on Traceability in Laboratory Medicine. PMID:23327864

Since ISO (International Organization for Standardization) 15189 for medical laboratories was established in Japan in 2003, 60 medical laboratories had been certified until April 2011. Among them, 10 medical laboratories belong to national university hospitals. To investigate the current status for the development of a quality management system, we carried out a questionnaire survey targeting all national university hospitals. ISO and ISO 15189 have already been introduced in about 70% of all laboratories and 53% are ready to accept them. In medical laboratories that have already accepted ISO 15189, it was suggested that their quality management systems have been functioning effectively and a gradual decrease of the number of the incidents has been confirmed.

Slew maneuvers of Spacecraft Control Laboratory Experiment (SCOLE)  

NASA Technical Reports Server (NTRS)

This is the final report on the dynamics and control of slew maneuvers of the Spacecraft Control Laboratory Experiment (SCOLE) test facility. The report documents the basic dynamical equation derivations for an arbitrary large angle slew maneuver as well as the basic decentralized slew maneuver control algorithm. The set of dynamical equations incorporate rigid body slew maneuver and three dimensional vibrations of the complete assembly comprising the rigid shuttle, the flexible beam, and the reflector with an offset mass. The analysis also includes kinematic nonlinearities of the entire assembly during the maneuver and the dynamics of the interactions between the rigid shuttle and the flexible appendage. The equations are simplified and evaluated numerically to include the first ten flexible modes to yield a model for designing control systems to perform slew maneuvers. The control problem incorporates the nonlinear dynamical equations and is expressed in terms of a two point boundary value problem.

Sorting things out through ER quality control  

PubMed Central

The endoplasmic reticulum (ER) is a highly organized and specialized organelle optimized for the production of proteins. It is comprised of a highly interconnected network of tubules that contain a large set of resident proteins dedicated to the maturation and processing of proteins that traverse the eukaryotic secretory pathway. As protein maturation is an imperfect process, frequently resulting in misfolding and/or the formation of aggregates, proteins are subjected to a series of evaluation processes within the ER. Proteins deemed native are sorted for anterograde trafficking, while immature or non-native proteins are initially retained in the ER in an attempt to rescue the aberrant products. Terminally misfolded substrates are eventually targeted for turnover through the ER-associated degradation or ERAD pathway to protect the cell from the release of a defective product and to recycle its components. A clearer picture of the identity of the machinery involved in these quality control evaluation processes and their mechanisms of actions has emerged over the past decade. PMID:20553226

The quality control theory of aging  

PubMed Central

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. PMID:24891937

Quality control of diffusion weighted images  

NASA Astrophysics Data System (ADS)

Diffusion Tensor Imaging (DTI) has become an important MRI procedure to investigate the integrity of white matter in brain in vivo. DTI is estimated from a series of acquired Diffusion Weighted Imaging (DWI) volumes. DWI data suffers from inherent low SNR, overall long scanning time of multiple directional encoding with correspondingly large risk to encounter several kinds of artifacts. These artifacts can be too severe for a correct and stable estimation of the diffusion tensor. Thus, a quality control (QC) procedure is absolutely necessary for DTI studies. Currently, routine DTI QC procedures are conducted manually by visually checking the DWI data set in a gradient by gradient and slice by slice way. The results often suffer from low consistence across different data sets, lack of agreement of different experts, and difficulty to judge motion artifacts by qualitative inspection. Additionally considerable manpower is needed for this step due to the large number of images to QC, which is common for group comparison and longitudinal studies, especially with increasing number of diffusion gradient directions. We present a framework for automatic DWI QC. We developed a tool called DTIPrep which pipelines the QC steps with a detailed protocoling and reporting facility. And it is fully open source. This framework/tool has been successfully applied to several DTI studies with several hundred DWIs in our lab as well as collaborating labs in Utah and Iowa. In our studies, the tool provides a crucial piece for robust DTI analysis in brain white matter study.

Reactive control and reasoning assistance for scientific laboratory instruments  

NASA Technical Reports Server (NTRS)

Scientific laboratory instruments that are involved in chemical or physical sample identification frequently require substantial human preparation, attention, and interactive control during their operation. Successful real-time analysis of incoming data that supports such interactive control requires: (1) a clear recognition of variance of the data from expected results; and (2) rapid diagnosis of possible alternative hypotheses which might explain the variance. Such analysis then aids in decisions about modifying the experiment protocol, as well as being a goal itself. This paper reports on a collaborative project at the NASA Ames Research Center between artificial intelligence researchers and planetary microbial ecologists. Our team is currently engaged in developing software that autonomously controls science laboratory instruments and that provides data analysis of the real-time data in support of dynamic refinement of the experiment control. the first two instruments to which this technology has been applied are a differential thermal analyzer (DTA) and a gas chromatograph (GC). coupled together, they form a new geochemicstry and microbial analysis tool that is capable of rapid identification of the organiz and mineralogical constituents in soils. The thermal decomposition of the minerals and organics, and the attendance release of evolved gases, provides data about the structural and molecular chemistry of the soil samples.

Low-Speed Active Flow Control Laboratory Developed  

NASA Technical Reports Server (NTRS)

The future of aviation propulsion systems is increasingly focused on the application of control technologies to significantly enhance the performance of a new generation of air vehicles. Active flow control refers to a set of technologies that manipulate the flow of air and combustion gases deep within the confines of an engine to dynamically alter its performance during flight. By employing active flow control, designers can create engines that are significantly lighter, are more fuel efficient, and produce lower emissions. In addition, the operating range of an engine can be extended, yielding safer transportation systems. The realization of these future propulsion systems requires the collaborative development of many base technologies to achieve intelligent, embedded control at the engine locations where it will be most effective. NASA Glenn Research Center s Controls and Dynamics Technology Branch has developed a state-of-the-art low-speed Active Flow Control Laboratory in which emerging technologies can be integrated and explored in a flexible, low-cost environment. The facility allows the most promising developments to be prescreened and optimized before being tested on higher fidelity platforms, thereby reducing the cost of experimentation and improving research effectiveness.

Los Alamos National Laboratory transuranic waste quality assurance project plan. Revision 1  

SciTech Connect

This Transuranic (TRU) Waste Quality Assurance Project Plan (QAPjP) serves as the quality management plan for the characterization of transuranic waste in preparation for certification and transportation. The Transuranic Waste Characterization/Certification Program (TWCP) consists of personnel who sample and analyze waste, validate and report data; and provide project management, quality assurance, audit and assessment, and records management support, all in accordance with established requirements for disposal of TRU waste at the Waste Isolation Pilot Plant (WIPP) facility. This QAPjP addresses how the TWCP meets the quality requirements of the Carlsbad Area Office (CAO) Quality Assurance Program Description (QAPD) and the technical requirements of the Transuranic Waste Characterization Quality Assurance Program Plan (QAPP). The TWCP characterizes and certifies retrievably stored and newly generated TRU waste using the waste selection, testing, sampling, and analytical techniques and data quality objectives (DQOs) described in the QAPP, the Los Alamos National Laboratory Transuranic Waste Certification Plan (Certification Plan), and the CST Waste Management Facilities Waste Acceptance Criteria and Certification [Los Alamos National Laboratory (LANL) Waste Acceptance Criteria (WAC)]. At the present, the TWCP does not address remote-handled (RH) waste.

External failures as descriptor of quality in clinical microbiology laboratory services.  

PubMed

This study employed customer feedback surveys to assess the quality of the laboratory services provided by an accredited clinical microbiology laboratory. The purpose of the study was to classify external failures and determine the quantity of such errors, and to establish how much time was spent processing and correcting these errors, together with the costs arising. The study indicates that the quality of laboratory test results can be regarded as good based on the accuracy of the result. Customer needs were also well taken into account in practice because of the good quality of the service. However, improvements are required in providing customers with test results without delay. The cost of processing and correcting such errors was negligible. The use of a customer feedback system allows systematic monitoring of external failures. In the accredited laboratory under study, it is unnecessary to monitor continually the costs and working time involved in processing and correcting external failures. The most essential point is to monitor the effects of the quality measures taken to reduce the number of failures. PMID:15653443

Improved Undergraduate Astronomy Laboratories with A Modern Telescope Control System  

NASA Astrophysics Data System (ADS)

We are in the middle of a cooperative astronomy education project to improve undergraduate laboratories at RPI (a PhD granting institution) and Siena College (a nearby liberal arts college). We have completed an overhaul of a 40-year-old, 16" B&C telescope on the RPI campus, and have made it available for hundreds of students at both schools, and once per week to the public. We have written an assessment test which was distributed to the students at the beginning and end of the Fall 2006 semester, which will be used as a baseline to determine whether the laboratory activities, which are currently under development, improve student learning in the Fall 2007 semester next year. The studio-style, hands-on, inquiry-based laboratories will be designed to challenge student misconceptions. In order to handle a large number of students using the main telescope and a limited number of smaller telescopes, we will cycle students through concurrent activities. This is enabled by the rapid acquisition and imaging of targets made possible by the upgrade to the control system of our 16" telescope. We demonstrate the productivity of our newly refurbished telescope, show the baseline results of our assessment, and present samples of activities under development. This project is funded by an NSF CCLI grant, 05-11340.

Dirithromycin disc susceptibility tests: interpretative criteria and quality control parameters.  

PubMed

Dirithromycin and its bioactive metabolite (erythromycylamine) were compared in vitro to erythromycin against 450 bacterial isolates. Dirithromycin and erythromycylamine did not differ in their in-vitro activity and the two compounds were additive when combined in equal proportions. Both compounds were active against erythromycin-susceptible bacteria but erythromycin was two to four times more potent on a weight-to-weight basis. Interpretive criteria for dirithromycin were not based on achievable blood concentrations since tissue concentrations may be 20-30 times greater than peak serum levels. Dirithromycin-susceptible strains were those with zones > or = 19 mm in diameter (15 micrograms dirithromycin disc) or MIC < or = 2.0 mg/L and resistance was defined as a zone < or = 15 mm or MIC > or = 8.0 mg/L. Interpretive criteria for testing Haemophilus influenzae on Haemophilus Test Medium (HTM) agar were not defined because of the drug's poor activity in the test system used. Two multi-laboratory studies were also undertaken, one to define quality control limits for disc diffusion tests and the other to define broth microdilution MIC control limits for tests with dirithromycin.

The Alzheimer’s Association external quality control program for cerebrospinal fluid biomarkers  

PubMed Central

Background The cerebrospinal fluid (CSF) biomarkers amyloid ? (A?)-42, total-tau (T-tau), and phosphorylated-tau (P-tau) demonstrate good diagnostic accuracy for Alzheimer’s disease (AD). However, there are large variations in biomarker measurements between studies, and between and within laboratories. The Alzheimer’s Association has initiated a global quality control program to estimate and monitor variability of measurements, quantify batch-to-batch assay variations, and identify sources of variability. In this article, we present the results from the first two rounds of the program. Methods The program is open for laboratories using commercially available kits for A?, T-tau, or P-tau. CSF samples (aliquots of pooled CSF) are sent for analysis several times a year from the Clinical Neurochemistry Laboratory at the Molndal campus of the University of Gothenburg, Sweden. Each round consists of three quality control samples. Results Forty laboratories participated. Twenty-six used INNOTESTenzyme-linked immunosorbent assay kits, 14 used Luminex xMAP with the INNO-BIA AlzBio3 kit (both measure A?-(1-42), P-tau(181P), and T-tau), and 5 used Meso Scale Discovery with the A? triplex (A?N-42, A?N-40, and A?N-38) or T-tau kits. The total coefficients of variation between the laboratories were 13% to 36%. Five laboratories analyzed the samples six times on different occasions. Within-laboratory precisions differed considerably between biomarkers within individual laboratories. Conclusions Measurements of CSF AD biomarkers show large between-laboratory variability, likely caused by factors related to analytical procedures and the analytical kits. Standardization of laboratory procedures and efforts by kit vendors to increase kit performance might lower variability, and will likely increase the usefulness of CSF AD biomarkers. PMID:21784349

Risk-Reliability Programming for Optimal Water Quality Control  

NASA Astrophysics Data System (ADS)

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.

Longitudinal flying qualities and controller design for nonlinear aircraft  

NASA Astrophysics Data System (ADS)

This thesis presents an analysis tool which predicts longitudinal flying qualities of aircraft subject to elevator rate limiting and nonlinear stick gradient. Our method is based on pilot-in-the-loop analysis and provides an explicit mathematical pilot model for nonlinear aircraft. Using pilot-in-the-loop simulation, flying qualities metrics can be computed for evaluation of the level of flying qualities. The proposed method is validated using real flight data. An aircraft compensator design methodology (CAWCOM) is also presented that improves the flying qualities despite the aircraft nonlinearities. As a result, the control system obtained by the CAWCOM methodology achieved the design goal of improving flying qualities both in terms of reducing the pilot's workload and enhancing the tracking performance. Pilot modeling to represent human pilot's nonlinear behavior and controller design that augments the pilot-vehicle closed-loop system for flying qualities enhancement are the key subjects of this research.

Laboratory Transferability of Optimally Shaped Laser Pulses for Quantum Control  

E-print Network

Optimal control experiments can readily identify effective shaped laser pulses, or "photonic reagents", that achieve a wide variety of objectives. For many practical applications, an important criterion is that a particular photonic reagent prescription still produce a good, if not optimal, target objective yield when transferred to a different system or laboratory, {even if the same shaped pulse profile cannot be reproduced exactly. As a specific example, we assess the potential for transferring optimal photonic reagents for the objective of optimizing a ratio of photoproduct ions from a family of halomethanes through three related experiments.} First, applying the same set of photonic reagents with systematically varying second- and third-order chirp on both laser systems generated similar shapes of the associated control landscape (i.e., relation between the objective yield and the variables describing the photonic reagents). Second, optimal photonic reagents obtained from the first laser system were found to still produce near optimal yields on the second laser system. Third, transferring a collection of photonic reagents optimized on the first laser system to the second laser system reproduced systematic trends in photoproduct yields upon interaction with the homologous chemical family. Despite inherent differences between the two systems, successful and robust transfer of photonic reagents is demonstrated in the above three circumstances. The ability to transfer photonic reagents from one laser system to another is analogous to well-established utilitarian operating procedures with traditional chemical reagents. The practical implications of the present results for experimental quantum control are discussed.

Quality assurance guidance for laboratory assessment plates in support of EM environmental sampling and analysis activities  

SciTech Connect

This document is one of several guidance documents developed to support the EM (DOE Environmental Restoration and Waste Management) Analytical Services program. Its purpose is to introduce assessment plates that can be used to conduct performance assessments of an organization`s or project`s ability to meet quality goals for analytical laboratory activities. These assessment plates are provided as non-prescriptive guidance to EM-support organizations responsible for collection of environmental data for remediation and waste management programs at DOE facilities. The assessments evaluate objectively all components of the analytical laboratory process to determine their proper selection and use.

TSX-Plus for laboratory data acquisition and control  

SciTech Connect

TSX-Plus is a multi-user operating system for PDP-11 and LSI-11 computers, which offers many of the features available with the DEC RSX-11M. For present users of RT-11 who wish to upgrade to a multi-user operating system, TSX-Plus offers several advantages over RSX-11M, such as lower cost and software compatibility with RT-11. TSX-Plus maintains a similarity with RT-11 by employing the RT-11 utility programs and device drivers; also, the RT-11 monitor commands are a subset of the TSX-Plus commands. Laboratory applications of TSX-Plus are discussed, and a set of FORTRAN callable subroutines, which are useful for data acquisition and hardware control, are presented. Also, the use of hardware interrupt and trap instructions (software interrupt) under TSX-Plus are discussed.

Radiative transfer theory verified by controlled laboratory experiments.  

PubMed

We report the results of high-accuracy controlled laboratory measurements of the Stokes reflection matrix for suspensions of submicrometer-sized latex particles in water and compare them with the results of a numerically exact computer solution of the vector radiative transfer equation (VRTE). The quantitative performance of the VRTE is monitored by increasing the volume packing density of the latex particles from 2% to 10%. Our results indicate that the VRTE can be applied safely to random particulate media with packing densities up to ?2%. VRTE results for packing densities of the order of 5% should be taken with caution, whereas the polarized bidirectional reflectivity of suspensions with larger packing densities cannot be accurately predicted. We demonstrate that a simple modification of the phase matrix entering the VRTE based on the so-called static structure factor can be a promising remedy that deserves further examination.

Manned Space-laboratories Control Center (MSCC) operations concept  

NASA Technical Reports Server (NTRS)

The initiation of the (German-) nationally funded control center for manned spaceflight operations triggered by the invitation of President Reagan to ESA, Japan, and Canada in 1984 to join the International Space Station Freedom Program is recalled. The requirements for a Manned Space-Laboratories Control Center (MSCC) as defined at the beginning of the planning and construction process in 1987 and the resulting modifications during the various programmatic scenario changes on NASA and ESA side between 1987 and now are presented. The validity of the original requirements with respect to the current scenario, which asks for a logical evolution from the execution of the D-2 mission in January 1993 via the European Columbus Precursor flights (in particular the E-1 mission) towards Columbus Attached Laboratory (APM)-operations by the end of this century are discussed. The resulting tasks of the MSCC for the various missions, the current configuration, and the ensuing operations concept leading from a more centralized concept for D-2 towards a decentralized payload operations concept for the APM and the implications with respect to European and International interfaces are presented. The planned Columbus MSCC facility architecture and its expected modifications introduced by the ESA Ministerial Conference in Munich (Nov. 1991) and follow-on discussions are briefly addressed. The last chapter outlines the planned services to be provided by the MSCC to the decentralized User (experimenter) community. Issues like decentralized mission planning on executional level, command validation, data flow coordination, archiving services, and telescience capabilities are highlighted from a MSCC point of view.

Quality control of liquid scintillation counters.  

PubMed

Liquid scintillation counting (LSC) is widely used at LNHB for primary standardization of radionuclides (TDCR method), for secondary calibration and also for source stability studies or radioactive purity measurements. A total of five LSC counters are used for these purposes: two locally developed 3-photodetector counters for the implementation of the TDCR method, two Wallac 1414 counters and one Wallac 1220 Quantulus counter. The quality of the LSC measurements relies on the correct operation of these counters and their traceability to the frequency and time units. PMID:16621583

Crowdsourcing Quality Control of Online Information: A Quality-Based Cascade Model  

NASA Astrophysics Data System (ADS)

We extend previous cascade models of social influence to investigate how the exchange of quality information among users may moderate cascade behavior, and the extent to which it may influence the effectiveness of collective user recommendations on quality control of information. We found that while cascades do sometimes occur, their effects depend critically on the accuracies of individual quality assessments of information contents. Contrary to predictions of cascade models of information flow, quality-based cascades tend to reinforce the propagation of individual quality assessments rather than being the primary sources that drive the assessments. We found even small increase in individual accuracies will significantly improve the overall effectiveness of crowdsourcing quality control. Implication to domains such as online health information Web sites or product reviews are discussed.

Quality control throughout the production process of infant food.  

PubMed

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. PMID:22699770

Air quality and pollution control in Taiwan  

NASA Astrophysics Data System (ADS)

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.

Flying qualities - A costly lapse in flight-control design  

NASA Technical Reports Server (NTRS)

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.

Laboratory transferability of optimally shaped laser pulses for quantum control  

NASA Astrophysics Data System (ADS)

Optimal control experiments can readily identify effective shaped laser pulses, or "photonic reagents," that achieve a wide variety of objectives. An important additional practical desire is for photonic reagent prescriptions to produce good, if not optimal, objective yields when transferred to a different system or laboratory. Building on general experience in chemistry, the hope is that transferred photonic reagent prescriptions may remain functional even though all features of a shaped pulse profile at the sample typically cannot be reproduced exactly. As a specific example, we assess the potential for transferring optimal photonic reagents for the objective of optimizing a ratio of photoproduct ions from a family of halomethanes through three related experiments. First, applying the same set of photonic reagents with systematically varying second- and third-order chirp on both laser systems generated similar shapes of the associated control landscape (i.e., relation between the objective yield and the variables describing the photonic reagents). Second, optimal photonic reagents obtained from the first laser system were found to still produce near optimal yields on the second laser system. Third, transferring a collection of photonic reagents optimized on the first laser system to the second laser system reproduced systematic trends in photoproduct yields upon interaction with the homologous chemical family. These three transfers of photonic reagents are demonstrated to be successful upon paying reasonable attention to overall laser system characteristics. The ability to transfer photonic reagents from one laser system to another is analogous to well-established utilitarian operating procedures with traditional chemical reagents. The practical implications of the present results for experimental quantum control are discussed.

Aquatic macroinvertebrates and water quality of Sandia Canyon, Los Alamos National Laboratory, November 1993--October 1994  

SciTech Connect

The Ecological Studies Team (EST) of ESH-20 at Los Alamos National Laboratory (LANL) has collected samples from the stream within Sandia Canyon since the summer of 1990. These field studies gather water quality measurements and collect aquatic macroinvertebrates from permanent sampling sites. Reports by Bennett (1994) and Cross (1994) discuss previous EST aquatic studies in Sandia Canyon. This report updates and expands those findings. EST collected water quality data and aquatic macroinvertebrates at five permanent stations within the canyon from November 1993 through October 1994. The two upstream stations are located below outfalls that discharge industrial and sanitary waste effluent into the stream, thereby maintaining year-round flow. Some water quality parameters are different at the first three stations from those expected of natural streams in the area, indicating degraded water quality due to effluent discharges. The aquatic habitat at the upper stations has also been degraded by sedimentation and channelization. The macroinvertebrate communities at these stations are characterized by low diversities and unstable communities. In contrast, the two downstream stations appear to be in a zone of recovery, where water quality parameters more closely resemble those found in natural streams of the area. The two lower stations have increased macroinvertebrate diversity and stable communities, further indications of downstream water quality improvement.

Development of veterinary laboratory networks for avian influenza and other emerging infectious disease control: the southeast asian experience.  

PubMed

The outbreak of highly pathogenic H5N1 avian influenza, with its international spread, confirmed that emerging infectious disease control must be underpinned by effective laboratory services. Laboratory results are the essential data underpinning effective surveillance, case diagnosis, or monitoring of responses. Importantly, laboratories are best managed within national and international networks of technological support rather than in isolation. A well planned laboratory network can deliver both a geographical spread of testing capacity and also a cost effective hierarchy of capability. Hence in the international context regional networks can be particularly effective. Laboratories are an integral part of a country's veterinary services and their role and function should be clearly defined in the national animal health strategy and supporting government policies. Not every laboratory should be expected to deliver every possible service, and integration into regional and broader international networks should be a part of the overall strategy. The outputs required of each laboratory should be defined and then ensured through accredited quality assurance. The political and scientific environment in which laboratories operate changes continuously, not only through evolving national and regional animal health priorities but also through new test technologies and enhancements to existing technologies. Active networks help individual laboratories to monitor, evaluate, and respond to such challenges and opportunities. The end result is enhanced emerging infectious disease preparedness across the region. PMID:24504903

Laboratory Investigations into Micromechanical Mechanisms Controlling Earthquake Nucleation  

NASA Astrophysics Data System (ADS)

Improving our understanding of factors controlling spontaneous shear rupture nucleation on a frictional fault would help better define the important physical processes contributing to earthquake rupture and faulting. Our current laboratory investigations quantify the local stress states on a laboratory fault, which control the transition of sliding from stable (quasi-static) to unstable (dynamic), commonly referred to as earthquake nucleation. A fault is experimentally modeled using two Poly(methyl methacrylate) samples in a direct shear configuration. During nucleation, we observed sudden, elastodynamic stress changes using an array of 16 acoustic emission (AE) sensors. Measurements of absolute displacement from these sensors allowed us to characterize general source mechanics using moment tensor inversion. This technique is widely used in seismology and we observe double-couple (DC) focal mechanisms; a source commonly used to characterize in situ earthquakes. During nucleation, we sometimes observe swarms of smaller, ';foreshock' earthquakes (Mw ~ -7), localized in time and space, prior to the incipient mainshock (Mw ~ -3.25). In general, the local perturbations in the stress field induced by the stress drop (??) from a single foreshock was insufficient to cause the subsequent foreshock at the spatial distances recorded experimentally. This implied that the underlying process driving the foreshock sequence (and eventual mainshock) was aseismic slip over the nucleation zone recorded using non-contact sensors. Spatio-temporal distributions of the foreshocks and the near-fault aseismic motions were shown to be directly related to: i) the rate at which the average bulk stress accumulates across the fault (d?f /dt) and ii) the heterogeneity of normal stress caused by the irregular distribution of asperities, respectively. (A) Locations of the foreshocks (FS1-FS9) determined using p-wave travel times from multiple AE sensors. The locations were superimposed on interfacial pressure measurements obtained using pressure sensitive film (high normal stresses appear as red). (B) Enhanced view of the location of FS6 on the pressure sensitive film. (C) Results of moment tensor inversion (red) fitting the experimental data (black) measured by five AE sensors (PZ7-PZ12) for FS6.

CRN5EXP: Expert system for statistical quality control  

NASA Technical Reports Server (NTRS)

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.

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

PubMed

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. PMID:9166255

Report on the audit of the Savannah River Site`s quality control program for groundwater sampling  

SciTech Connect

The Savannah River Site`s groundwater remediation program was managed by the Department of Energy`s (Department) management and operating contractor for the site, Westinghouse Savannah River Company (Westinghouse). One component of the remediation program was the quality control program. The goal of the groundwater quality control program was to ensure that the results of laboratory analyses of groundwater samples were accurate and precise so that they could be relied upon for making remediation decisions. The objective of this audit was to determine whether Westinghouse acquired the minimal number of laboratory analyses required to ensure that groundwater sampling results met this criteria.

The origin, effects and control of air pollution in laboratories used for human embryo culture.  

PubMed

Testing shows that most laboratories conducting human gamete and embryo culture have air quality and sources of contamination that exceed the levels measured in homes, businesses and schools. The sources of these contaminants have been shown to be either from activities outside the laboratory, or emitted from materials used in the facility, such as compressed gas, cleaning and sterilizing agents, plastic and stored materials. Both the laboratory structure and the air handling systems may affect the air composition. The significance of these findings is being validated by the accumulation of field case studies and now by assay procedures. Products given off by road sealant were shown to have accumulated in one of the examined laboratories, adjacent to a large re-surfaced parking area. Aldehydes such as acrolein, hexanal, decanal, pentanal and others were detected at elevated concentrations that were statistically significant. Since it is not appropriate to add potentially suspect chemicals to human embryos, we used a mouse-model to study the effect of acrolein. The growth of mouse embryos was significantly affected after acrolein was added at different concentrations to the culture environment. The physiological effect was noted at concentrations in the low ppm range. The testing end-point of embryo death must still be considered to be a crude basis for evaluating toxicological effects, since it involves addition of compounds to culture media and unprotected growth until the blastocyst stage. The findings may, however, support observations of decreased pregnancy rate following exposure of human embryos to aldehydes or other adverse conditions. With proper engineering and material selection, it is possible to reduce such contamination. The usefulness of this approach for controlling aldehydes has been demonstrated by decreasing levels in the laboratory to below those of the outside air. PMID:10091065

The use of total quality principles to achieve regulatory compliance in research laboratories.  

PubMed

Since the late 1980s, the U.S. Food and Drug Administration (FDA) has increased its focus on regulatory compliance. This is evidenced by an increase in warning letters, product seizures, injunctions, prosecutions, and recalls. This increased level of FDA enforcement activity is evidenced across all of the compliance regulations. Thus, the ability to comply with the Good Laboratory Practices (GLPs). Good Clinical Practices (GCPs) and Good Manufacturing Practices regulations could result in FDA enforcement activities and delays in the approval process for new products. Therefore, the ability to achieve compliance with the GLPs, GCPs, and GMPs in research laboratories is a key to business success in the 1990s. Applying the principles of total quality is one way to address these important business issues. The principles of total quality (customer focus, improvement, involvement, leadership, and measurement) provide a methodology for ensuring success in a rapidly changing regulatory environment. The FDA needs to be treated as a customer by research organizations. Valid regulatory requirements need to be negotiated with the agency. Once these customer requirements have been identified, the quality unit needs to play a leadership role in translating these requirements into action plans. Quality units, no matter how skillful or good, cannot achieve success without involvement of the scientific staff and management group of their organizations. Without their involvement there will be no organizational commitment to compliance programs undertaken to meet the valid requirements of the FDA. Meeting these valid customer requirements will require improvement efforts. The many tools of quality improvement in achieving the desired improvements.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:8520863

XPAD X-ray hybrid pixel detector for charge density quality diffracted intensities on laboratory equipment.  

PubMed

The new generation of X-ray detectors, the hybrid pixel area detectors or `pixel detectors', is based on direct detection and single-photon counting processes. A large linearity range, high dynamic and extremely low noise leading to an unprecedented high signal-to-noise ratio, fast readout time (high frame rates) and an electronic shutter are among their intrinsic characteristics which render them very attractive. First used on synchrotron beamlines, these detectors are also promising in the laboratory, in particular for pump-probe or quasi-static experiments and accurate electron density measurements, as explained in this paper. An original laboratory diffractometer made from a Nonius Mach3 goniometer equipped with an Incoatec Mo microsource and an XPAD pixel area detector has been developed at the CRM2 laboratory. Mo K? accurate charge density quality data up to 1.21?Å(-1) resolution have been collected on a sodium nitroprusside crystal using this home-made diffractometer. Data quality for charge density analysis based on multipolar modelling are discussed in this paper. Deformation electron densities are compared to those already published (based on data collected with CCD APEXII and CAD4 diffractometers). PMID:25274511

Sediment laboratory quality-assurance project: studies of methods and materials  

USGS Publications Warehouse

In August 1996 the U.S. Geological Survey initiated the Sediment Laboratory Quality-Assurance project. The Sediment Laboratory Quality Assurance project is part of the National Sediment Laboratory Quality-Assurance program. This paper addresses the fmdings of the sand/fme separation analysis completed for the single-blind reference sediment-sample project and differences in reported results between two different analytical procedures. From the results it is evident that an incomplete separation of fme- and sand-size material commonly occurs resulting in the classi?cation of some of the fme-size material as sand-size material. Electron microscopy analysis supported the hypothesis that the negative bias for fme-size material and the positive bias for sand-size material is largely due to aggregation of some of the ?ne-size material into sand-size particles and adherence of ?ne-size material to the sand-size grains. Electron microscopy analysis showed that preserved river water, which was low in dissolved solids, speci?c conductance, and neutral pH, showed less aggregation and adhesion than preserved river water that was higher in dissolved solids and speci?c conductance with a basic pH. Bacteria were also found growing in the matrix, which may enhance fme-size material aggregation through their adhesive properties. Differences between sediment-analysis methods were also investigated as pan of this study. Suspended-sediment concentration results obtained from one participating laboratory that used a total-suspended solids (TSS) method had greater variability and larger negative biases than results obtained when this laboratory used a suspended-sediment concentration method. When TSS methods were used to analyze the reference samples, the median suspended sediment concentration percent difference was -18.04 percent. When the laboratory used a suspended-sediment concentration method, the median suspended-sediment concentration percent difference was -2.74 percent. The percent difference was calculated as follows: Percent difference = (( reported mass - known mass)/known mass ) X 100.

Demystifying ratings: How flow control shocks credit quality  

SciTech Connect

Financial operations of many solid waste systems, waste-to-energy facilities in particular, have been shocked by the lack of congressional, and state and local legislation to resolve the loss of legal flow control. Flow control is a system's legal authority to direct waste into its own facilities. In contrast is economic flow control, where the market factors prevail and waste is brought to a facility based on competitive pricing. The loss of legal flow control threatens solid waste systems and impinges their underlying credit quality. Credit quality is expressed as the bond rating, a statement about the borrowers ability and willingness to repay debt in full and on time. While the courts have identified acceptable alternatives to enable municipal systems to diversity revenues (creating revenue flexibility), such alternatives may not be palatable as they represent additional taxation or fees. The paper highlights how the loss of legal flow control has shocked the operations, management and credit quality of solid waste systems. These shocks have stimulated public and private partnerships in order to facilitate economic flow control. Municipal credit solutions, credit impacts and credit trends are explained to identify how solid waste systems have responded in an operating climate exacerbated by regulatory changes (environmental and accounting) as well as utility deregulations. Analytical considerations are presented for evaluating the credit quality of solid waste bonds.

The Quality Control of the LHC Continuous Cryostat Interconnections  

E-print Network

The interconnections between the Large Hadron Collider (LHC) magnets have required some 40 000 TIG welded joints and 65 000 electrical splices. At the level of single joints and splices, non-destructive techniques find limited application: quality control is based on the qualification of the process and of operators, on the recording of production parameters and on production samples. Visual inspection and process audits were the main techniques used. At the level of an extended chain of joints and splices - from a 53.5 m half-cell to a complete 2.7 km arc sector - quality control is based on vacuum leak tests, electrical tests and RF microwave reflectometry that progressively validated the work performed. Subsequent pressure tests, cryogenic circuits flushing with high pressure helium and cool-downs revealed a few unseen or new defects. This paper presents an overview of the quality control techniques used, seeking lessons applicable to similar large, complex projects.

Exercise Training Restores Cardiac Protein Quality Control in Heart Failure  

PubMed Central

Exercise training is a well-known coadjuvant in heart failure treatment; however, the molecular mechanisms underlying its beneficial effects remain elusive. Despite the primary cause, heart failure is often preceded by two distinct phenomena: mitochondria dysfunction and cytosolic protein quality control disruption. The objective of the study was to determine the contribution of exercise training in regulating cardiac mitochondria metabolism and cytosolic protein quality control in a post-myocardial infarction-induced heart failure (MI-HF) animal model. Our data demonstrated that isolated cardiac mitochondria from MI-HF rats displayed decreased oxygen consumption, reduced maximum calcium uptake and elevated H2O2 release. These changes were accompanied by exacerbated cardiac oxidative stress and proteasomal insufficiency. Declined proteasomal activity contributes to cardiac protein quality control disruption in our MI-HF model. Using cultured neonatal cardiomyocytes, we showed that either antimycin A or H2O2 resulted in inactivation of proteasomal peptidase activity, accumulation of oxidized proteins and cell death, recapitulating our in vivo model. Of interest, eight weeks of exercise training improved cardiac function, peak oxygen uptake and exercise tolerance in MI-HF rats. Moreover, exercise training restored mitochondrial oxygen consumption, increased Ca2+-induced permeability transition and reduced H2O2 release in MI-HF rats. These changes were followed by reduced oxidative stress and better cardiac protein quality control. Taken together, our findings uncover the potential contribution of mitochondrial dysfunction and cytosolic protein quality control disruption to heart failure and highlight the positive effects of exercise training in re-establishing cardiac mitochondrial physiology and protein quality control, reinforcing the importance of this intervention as a non-pharmacological tool for heart failure therapy.

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. PMID:25272516

Guidelines for quality assurance and quality control of fish taxonomic data collected as part of the National Water-Quality Assessment Program  

USGS Publications Warehouse

Fish community structure is characterized by the U.S. Geological Survey's National Water-Quality Assessment (NAWQA) Program as part of a perennial, multidisciplinary approach to evaluating the physical, chemical, and biological conditions of the Nation's water resources. The objective of quality assurance and quality control of fish taxonomic data that are collected as part of the NAWQA Program is to establish uniform guidelines and protocols for the identification, processing, and archiving of fish specimens to ensure that accurate and reliable data are collected. Study unit biologists, collaborating with regional biologists and fish taxonomic specialists, prepare a pre-sampling study plan that includes a preliminary faunal list and identification of an ichthyological curation center for receiving preserved fish specimens. Problematic taxonomic issues and protected taxa also are identified in the study plan, and collecting permits are obtained in advance of sampling activities. Taxonomic specialists are selected to identify fish specimens in the field and to assist in determining what fish specimens should be sacrificed, fixed, and preserved for laboratory identification, independent taxonomic verification, and long-term storage in reference or voucher collections. Quantitative and qualitative sampling of fishes follows standard methods previously established for the NAWQA Program. Common ichthyological techniques are used to process samples in the field and prepare fish specimens to be returned to the laboratory or sent to an institutional repository. Taxonomic identifications are reported by using a standardized list of scientific names that provides nomenclatural consistency and uniformity across study units.

Performance of dust allergen carpet samplers in controlled laboratory studies.  

PubMed

Allergens and other pollutants in house dust are collected using a variety of dust samplers that are assumed to operate similarly. This factorial design study compared sampler performance under controlled environmental conditions. House dust with known particle sizes (212-90, 90-45, and <45??m) and allergen concentrations were sampled from new carpet squares with varying denier, pile height and pile densities. Dust mass and allergen recovery for total dust mites (Der p 1 and Der f 1), cat (Fel d 1) and cockroach allergen (Bla g 1) were assessed using the Eureka Mighty Mite (EURK), the High Volume Small Surface Sampler (HVS), or the American Industrial Hygiene Association (AIHA) method. Allergen concentrations were quantified using enzyme-linked immunosorbent assays, and dust mass results were corrected for carpet fiber shedding. Samplers were compared by exploring mass collection efficiency (CE=fiber corrected dust mass/applied dust mass) and concentration ratio (CR=allergen concentration in collected sample/allergen concentration in test dust). Test dust allergen concentrations varied by particle size fraction due to varying laboratory performance over time. The EURK and HVS samplers had CEs of 41-63% in the small and medium particle size fractions, and collected less than 20% of the available dust from the large size fraction. The AIHA CE ranged from 10% to 17% in the medium and small particle size fractions, but collected little dust in the largest particle size fraction. The AIHA and HVS samplers were more likely to acquire more representative and less variable allergen CRs compared with the EURK method. Health studies that use allergen concentration as an exposure metric need to consider the implications of sampler performance when interpreting links to health outcomes and development of health-based standards for allergens in house dust.

Setting the Standards: Quality Control in the Secretory Pathway  

NSDL National Science Digital Library

A variety of quality control mechanisms operate in the endoplasmic reticulum and in downstream compartments of the secretory pathway to ensure the fidelity and regulation of protein expression during cell life and differentiation. As a rule, only proteins that pass a stringent selection process are transported to their target organelles and compartments. If proper maturation fails, the aberrant products are degraded. Quality control improves folding efficiency by retaining proteins in the special folding environment of the endoplasmic reticulum, and it prevents harmful effects that could be caused by the deployment of incompletely folded or assembled proteins.

The World Health Organization's External Quality Assurance System Proficiency Testing Program Has Improved the Accuracy of Antimicrobial Susceptibility Testing and Reporting among Participating Laboratories Using NCCLS Methods  

PubMed Central

A total of 150 laboratories in 33 countries that followed the NCCLS testing procedures participated in the World Health Organization's External Quality Assurance System for Antimicrobial Susceptibility Testing (EQAS-AST) from January 1998 through March 2001. Laboratories tested seven bacterial isolates for antimicrobial resistance and reported the results to the Centers for Disease Control and Prevention (CDC) in Atlanta, Ga. The results were compared to the results generated at the CDC with the NCCLS broth microdilution and disk diffusion reference methods. Although there were few testing errors with Salmonella enterica subsp. enterica serovar Enteritidis, drugs that are not appropriate for therapy of Salmonella infections were tested and reported by 136 (91%) of 150 laboratories. In addition, 29 (20%) of 150 laboratories used the Staphylococcus aureus breakpoints to report oxacillin results for Staphylococcus saprophyticus. For a vanB-containing Enterococcus faecalis strain, 124 (83%) of 150 laboratories correctly reported vancomycin results that were ±1 doubling dilution from the reference MIC or ±3 mm from the reference disk diffusion result. Of the laboratories that tested Streptococcus agalactiae by disk diffusion, 17% reported nonsusceptible results for penicillin in error. While 110 laboratories (73%) tested the S. pneumoniae challenge isolate against a fluoroquinolone, 83% tested it against ciprofloxacin, for which there are no NCCLS interpretive criteria. Ten of 12 laboratories testing levofloxacin and 4 of 4 laboratories testing ofloxacin by an MIC method correctly reported resistant results for the isolate. Feedback letters sent to participating laboratories highlighted areas of susceptibility testing in individual laboratories that needed improvement. The positive impact of the feedback letters and the overall effectiveness of the EQAS program were documented in repeat testing challenges with pneumococci and staphylococci. The 31 and 19% increases in the numbers of laboratories using appropriate testing methods for pneumococci and staphylococci, respectively, in 2000 versus 1998 indicate that laboratory performance is improving.

A French national quality control study for the serological and molecular diagnosis of hepatitis delta virus (HDV) was organized. Total HDV antibodies were properly detected by all laboratories; 8/14 laboratories failed to detect low titers of IgM, and 6/11 failed to quantify and/or underestimated the RNA viral load in several samples. These discrepancies are likely related to the molecular diversity of HDV. PMID:24523467

Laboratory security and emergency response guidance for laboratories working with select agents. Centers for Disease Control and Prevention.  

PubMed

In recent years, concern has increased regarding use of biologic materials as agents of terrorism, but these same agents are often necessary tools in clinical and research microbiology laboratories. Traditional biosafety guidelines for laboratories have emphasized use of optimal work practices, appropriate containment equipment, well-designed facilities, and administrative controls to minimize risk of worker injury and to ensure safeguards against laboratory contamination. The guidelines discussed in this report were first published in 1999 (U.S. Department of Health and Human Services/CDC and National Institutes of Health. Biosafety in microbiological and biomedical laboratories [BMBL]. Richmond JY, McKinney RW, eds. 4th ed. Washington, DC: US Department of Health and Human Services, 1999 [Appendix F]). In that report, physical security concerns were addressed, and efforts were focused on preventing unauthorized entry to laboratory areas and preventing unauthorized removal of dangerous biologic agents from the laboratory. Appendix F of BMBL is now being revised to include additional information regarding personnel risk assessments, and inventory controls. The guidelines contained in this report are intended for laboratories working with select agents under biosafety-level 2, 3, or 4 conditions as described in Sections II and III of BMBL. These recommendations include conducting facility risk assessments and developing comprehensive security plans to minimize the probability of misuse of select agents. Risk assessments should include systematic, site-specific reviews of 1) physical security; 2) security of data and electronic technology systems; 3) employee security; 4) access controls to laboratory and animal areas; 5) procedures for agent inventory and accountability; 6) shipping/transfer and receiving of select agents; 7) unintentional incident and injury policies; 8) emergency response plans; and 9) policies that address breaches in security. The security plan should be an integral part of daily operations. All employees should be well-trained and equipped, and the plan should be reviewed annually, at least. PMID:12515340

Effect of current and forthcoming European legislation and standardization on the setting of quality specifications by laboratories.  

PubMed

A network of national and international guidelines and directives developed in the last few decades by various bodies will lead to a new concept of total quality for medical laboratory services comprising legislative regulations on national and international levels, standardizations backed up by legislation and recommendations of professional societies. One example is the IVD Directive of the European Community. It will not only stimulate accreditation in the field of laboratory medicine, but also necessitate numerous standardization activities which are presently co-ordinated by the European Committee for Standardization (CEN). Another standardization example is the development of quality management systems, mainly by ISO. The ISO 9000 series has become the most successful family of standards world-wide. Meanwhile, specific standards for the needs of laboratories (ISO 17025), and in particular of medical laboratories (ISO 15189), are being worked out. A new trend to develop quality management systems towards total quality management systems can be observed including additional aspects such as economic and quality interests of society, customers and owners of laboratories. The goal of all activities is to create a network of confidence which provides some guarantee to the clients, i.e. the physicians and their patients, that they will receive a high-quality medical laboratory service.

Research on visualization quality control of electronic map  

NASA Astrophysics Data System (ADS)

The realization of map functions is usually paid much more attention to than the visualization quality of map in the development of electronic map. As a result, the visualization effect of electronic map is unsatisfactory. The visualization quality of electronic map is directly related to user's understanding of geographical information and influences the application of electronic map. Along with extensive expansion and application of electronic map, visualization effect of electronic map has already become an important aspect to evaluate electronic map products. To examine the evaluation and the control techniques of electronic map visualization quality and to establish evaluation standards of electronic map visualization quality are of great significance at present. Based on the experiences in electronic map design, development of electronic map platform and professional application, the authors summarize several factors affecting visualization quality of electronic map: user interface, display capacity, visual effect, display speed, dynamic labeling, real-time display, legend and symbol design, and other aspects including temporal effect, mark effect, dynamic generalization, and dynamic projection. Combining with the practice in developing an electronic atlas system called eMapSee, the authors analyze related control techniques of visualization quality of electronic map from these aspects: friendly user interface, legibility and beauty of display effect, fast map display, real-time map display, and introduce how these techniques are used in practice.

Quality control of product/process using nondestructive control and possibilities of robotic investigation  

NASA Astrophysics Data System (ADS)

In this paper, the possibilities to improve the quality of products/processes using modern methods and equipment for non-destructive control are presented. The quality control is represented by the operation techniques and activities used to fulfil the conditions concerning the quality, it is a way to verify the realization of quality and to establish necessary actions to correct the non-conformities. The defectoscopy represents an assembly of methods to examine materials, prices and joins to discover their defects by non-destructive control methods. The essential requirements of non-destructive control, in connection with the imperatives of total quality's concept determinate in a short period of time a high attainment of systems' quality. In the second part of the paper, the possibility to achieve non-destructive control with the aid of robotic system, the appropriate cases in which the robots are useful, the type of robot together with constructive details are presented. The two main directions where the robotics is useful are non-destructive control in technological flux and the control in hostile or unapproachable environment for human operator. In the first case are used with proper software, and in the second, remote control robots. Finally, the advantage offered by the robot utilization for non- destructive control in special situations is emphasized.

Integrated evolutionary computation neural network quality controller for automated systems  

SciTech Connect

With increasing competition in the global market, more and more stringent quality standards and specifications are being demands at lower costs. Manufacturing applications of computing power are becoming more common. The application of neural networks to identification and control of dynamic processes has been discussed. The limitations of using neural networks for control purposes has been pointed out and a different technique, evolutionary computation, has been discussed. The results of identifying and controlling an unstable, dynamic process using evolutionary computation methods has been presented. A framework for an integrated system, using both neural networks and evolutionary computation, has been proposed to identify the process and then control the product quality, in a dynamic, multivariable system, in real-time.

Litter quality versus soil microbial community controls over decomposition: a quantitative analysis  

USGS Publications Warehouse

The possible effects of soil microbial community structure on organic matter decomposition rates have been widely acknowledged, but are poorly understood. Understanding these relationships is complicated by the fact that microbial community structure and function are likely to both affect and be affected by organic matter quality and chemistry, thus it is difficult to draw mechanistic conclusions from field studies. We conducted a reciprocal soil inoculum × litter transplant laboratory incubation experiment using samples collected from a set of sites that have similar climate and plant species composition but vary significantly in bacterial community structure and litter quality. The results showed that litter quality explained the majority of variation in decomposition rates under controlled laboratory conditions: over the course of the 162-day incubation, litter quality explained nearly two-thirds (64 %) of variation in decomposition rates, and a smaller proportion (25 %) was explained by variation in the inoculum type. In addition, the relative importance of inoculum type on soil respiration increased over the course of the experiment, and was significantly higher in microcosms with lower litter quality relative to those with higher quality litter. We also used molecular phylogenetics to examine the relationships between bacterial community composition and soil respiration in samples through time. Pyrosequencing revealed that bacterial community composition explained 32 % of the variation in respiration rates. However, equal portions (i.e., 16 %) of the variation in bacterial community composition were explained by inoculum type and litter quality, reflecting the importance of both the meta-community and the environment in bacterial assembly. Taken together, these results indicate that the effects of changing microbial community composition on decomposition are likely to be smaller than the potential effects of climate change and/or litter quality changes in response to increasing atmospheric CO2 concentrations or atmospheric nutrient deposition.

Certification, accreditation, and quality control in behavior analysis  

PubMed Central

Implementing quality control measures in the discipline and professional practice of behavior analysis is a challenging, but nevertheless important, step in the evolution of our field. The Association for Behavior Analysis currently seeks to ensure quality in behavior analysis by sponsoring an accreditation program for graduate academic programs and by promoting certification of individual practitioners. The accreditation reviews are conducted by ABA, whereas certification status is awarded by an independent, nonprofit credentialing entity: the Behavior Analyst Certification Board, Inc. Among the challenges that ABA faces as it pursues various quality control measures, particularly in its educational programs, are (a) how extensively should academic programs specify the verbal and nonverbal terminal repertoires in all three branches of behavior analysis (applied, experimental, and conceptual); (b) how extensively should programs that emphasize applied behavior analysis integrate science-based criteria for the evaluation of interventions; and (c) how extensively should programs that emphasize service delivery include training in formal research methodology.

An engineering approach to controlling indoor air quality.  

PubMed

Evidence is accumulating that indicates air quality problems in residential and commercial buildings are nearly always associated with inadequacies in building design and methods of operation. Thus, the very systems depended on to control the indoor environment can become indirect sources of contamination if diligence is not exercised at each stage of a building's life: a) planning and design, b) construction and commissioning, c) operation, and d) demolition or renovation. In this paper, an engineering perspective is presented in which the existing building stock is characterized in terms of its environmental performance. Preliminary data indicate that 20 to 30% of the existing buildings have sufficient problems to manifest as sick-building syndrome or building-related illness, while another 10 to 20% may have undetected problems. Thus, only about 50 to 70% of the existing buildings qualify as healthy buildings. Two methods and three mechanisms of control are described to achieve "acceptable" indoor air quality: source control and exposure control. If sources cannot be removed, some level of occupant exposure will result. To control exposures with acceptable values, the primary sensory receptors of the occupants (i.e., thermal, ocular, auditory, and olfactory) cannot be excessively stimulated. The three exposure control mechanisms are conduction, radiation, and convection. To achieve acceptable occupant responses, it is often practical to integrate the mechanisms of radiation and convection in heating, ventilating, and air conditioning systems that are designed to provide acceptable thermal, acoustic, and air quality conditions within occupied spaces.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:1821369

Liver phantom for quality control and training in nuclear medicine  

NASA Astrophysics Data System (ADS)

In nuclear medicine, liver scintigraphy aims to verify organ function based on the radionuclide concentration in the liver and bile flow and is also used to detect tumors. Therefore it is necessary to perform quality control tests in the gamma camera before running the exam to prevent false results. Quality control tests of the gamma camera should thus be performed before running the exam to prevent false results. Such tests generally use radioactive material inside phantoms for evaluation of gamma camera parameters in quality control procedures. Phantoms can also be useful for training doctors and technicians in nuclear medicine p
