    Bratton, Randolph M.

    1987-12-01

    This paper describes the design and implementation of the Air Force Institute of Technology's (AFIT's) UNIX-based VHDL Analyzer. The purpose of this tool is to facilitate the introduction of VHDL into the academic environment, which may not be able to use the Department of Defense's VMS-based software. This research emphasized two areas: the criteria for a production-quality software product and the design of an efficient Intermediate Representation (IR) that serves as an interface between the Analyzer and other tools in the AFIT VHDL Environment (AVE). Background on other UNIX VHDL analyzers, as well as other IRs, was presented. A two-part IR, based on Dallen's Patois hardware description language and named the VHDL Intermediate Access (VIA), was designed, and examples were given that illustrate its use. Test results showed that the Analyzer passed over 75 percent of the conformance tests from the VHDL VMS Analyzer Test Suite and performed well in the areas of compile time, memory usage, and disk usage. Recommendations for future research include adding user options to the Analyzer and implementing a design library for VHDL designs.

    2013-12-01

    The U.S. Geological Survey's Albuquerque Seismological Laboratory (ASL) has several efforts underway to improve data quality at its stations. The Data Quality Analyzer (DQA) is one such development. The DQA is designed to characterize station data quality in a quantitative and automated manner. Station quality is based on the evaluation of various metrics, such as timing quality, noise levels, sensor coherence, and so on. These metrics are aggregated into a measurable grade for each station. The DQA consists of a website, a metric calculator (Seedscan), and a PostgreSQL database. The website allows the user to make requests for various time periods, review specific networks and stations, adjust weighting of the station's grade, and plot metrics as a function of time. The website dynamically loads all station data from a PostgreSQL database. The database is central to the application; it acts as a hub where metric values and limited station descriptions are stored. Data is stored at the level of one sensor's channel per day. The database is populated by Seedscan. Seedscan reads and processes miniSEED data, to generate metric values. Seedscan, written in Java, compares hashes of metadata and data to detect changes and perform subsequent recalculations. This ensures that the metric values are up to date and accurate. Seedscan can be run in a scheduled task or on demand by way of a config file. It will compute metrics specified in its configuration file. While many metrics are currently in development, some are completed and being actively used. These include: availability, timing quality, gap count, deviation from the New Low Noise Model, deviation from a station's noise baseline, inter-sensor coherence, and data-synthetic fits. In all, 20 metrics are planned, but any number could be added. ASL is actively using the DQA on a daily basis for station diagnostics and evaluation. As Seedscan is scheduled to run every night, data quality analysts are able to then use the

    2013-01-01

    Quality is not a fixed or universal property of software; it depends on the context and goals of its stakeholders. Hence, when you want to develop a high-quality software system, the first step must be a clear and precise specification of quality. Yet even if you get it right and complete, you can be sure that it will become invalid over time. So the only solution is continuous quality control: the steady and explicit evaluation of a product's properties with respect to its updated quality goals.This book guides you in setting up and running continuous quality control in your environment.

    Verification of hematology analyzers (automated blood cell counters) is mandatory before new hematology analyzers may be used in routine clinical care. The verification process consists of several items which comprise among others: precision, accuracy, comparability, carryover, background and linearity throughout the expected range of results. Yet, which standard should be met or which verification limit be used is at the discretion of the laboratory specialist. This paper offers practical guidance on verification and quality control of automated hematology analyzers and provides an expert opinion on the performance standard that should be met by the contemporary generation of hematology analyzers. Therefore (i) the state-of-the-art performance of hematology analyzers for complete blood count parameters is summarized, (ii) considerations, challenges, and pitfalls concerning the development of a verification plan are discussed, (iii) guidance is given regarding the establishment of reference intervals, and (iv) different methods on quality control of hematology analyzers are reviewed. © 2016 John Wiley & Sons Ltd.

    2012-01-01

    RNA-based applications requiring high-quality, non-degraded RNA are a foundational element of many research studies. As such, it is paramount that the integrity of experimental RNA is validated prior to cDNA synthesis or other downstream applications. In the absence of expensive equipment such as microfluidic electrophoretic devices, and as an alternative to the costly and time-consuming standard formaldehyde gel, RNA quality can be quickly analyzed by adding small amounts of commercial bleach to TAE buffer-based agarose gels prior to electrophoresis. In the presence of low concentrations of bleach, the secondary structure of RNA is denatured and potential contaminating RNases are destroyed. Because of this, the 'bleach gel' is a functional approach that addresses the need for an inexpensive and safe way to evaluate RNA integrity and will improve the ability of researchers to rapidly analyze RNA quality.

    2016-06-01

    In 2014 the Institut Cartogràfic i Geològic de Catalunya (ICGC) decided to incorporate digital oblique imagery in its portfolio in response to the growing demand for this product. The reason can be attributed to its useful applications in a wide variety of fields and, most recently, to an increasing interest in 3d modeling. The selection phase for a digital oblique camera led to the purchase of the Leica RCD30 Oblique system, an 80MPixel multispectral medium-format camera which consists of one Nadir camera and four oblique viewing cameras acquiring images at an off-Nadir angle of 35º. The system also has a multi-directional motion compensation on-board system to deliver the highest image quality. The emergence of airborne oblique cameras has run in parallel to the inclusion of computer vision algorithms into the traditional photogrammetric workflows. Such algorithms rely on having multiple views of the same area of interest and take advantage of the image redundancy for automatic feature extraction. The multiview capability is highly fostered by the use of oblique systems which capture simultaneously different points of view for each camera shot. Different companies and NMAs have started pilot projects to assess the capabilities of the 3D mesh that can be obtained using correlation techniques. Beyond a software prototyping phase, and taking into account the currently immature state of several components of the oblique imagery workflow, the ICGC has focused on deploying a real production environment with special interest on matching the performance and quality of the existing production lines based on classical Nadir images. This paper introduces different test scenarios and layouts to analyze the impact of different variables on the geometric and radiometric performance.

    Water quality data for 65 variables were obtained for the period 1955 to 1977 and aggregated on a county basis. Measurements were taken primarily in New England and the Middle Atlantic States. When a subset of 138 counties with complete data was used, it was found that county aggregation statistical procedures resulted in data still able to describe the chemical characteristics of natural waters. Energy and socioeconomic data were merged with water quality data for these 138 counties. The path analytic methodology used by geneticists was adapted for use with these combined data to investigate for potential interactions between energy-related activities and water quality. A path diagram was proposed to provide insight into the possible causal nature of these interrelations. Direct and indirect pathways from energy production and use were traced to three factors describing functional attributes of water: conductivity, hardness, and dissolved metallic ions. This analysis explained 25 to 40% of the variance in three water quality factors and indicated the applicability of this technique to regional assessments of water quality impacts due to many human activities

    1989-01-01

    Historically, the productivity of a numerical reactor safety analyst has been hampered by several factors: poor mainframe computer turnaround for problem setup, checkout, and initialization; limited mainframe CPU allocation, accessibility and availability for transient advancement; lost or delayed output; and difficulty assimilating numerical results. Clearly, an economical engineering workstation capable of running RELAP5 interactively, and of simultaneously displaying the results in a coherent graphic fashion as they are produced, would alleviate many of these concerns. The RELAP5 desktop analyzer (RDA) is such a workstation. Although not yet capable of real-time simulation, the RDA will nevertheless reduce analysis costs and enhance analyst productivity since analysis cannot be done in real time anyway. The RDA is a microcomputer-based reactor transient simulation, visualization, and analysis tool developed at the Idaho National Engineering Laboratory (INEL) to assist an analyst in simulating and evaluating the transient behavior of nuclear power plants. The RDA integrates RELAP5 advanced best-estimate engineering simulation capabilities with on-line computer graphics routines allowing interactive reactor plant transient simulation and on-line analysis of results, or replay of past simulations, by means of graphic displays

They are supplemented by satisfying highly heterogeneous and complex motivations, representing highly diverse subjective functions associated to product until individualization for each type of consumption. Thus it observes highly surprising developments of subjective function associated with a product and which determines in the consumer's opinion the quality level of the product. The present study examines the role of associated services covering the subjective function of the product in view of the fact that the utility or subjective function is dependent on elements such as style, fashion and fads. Consumers will no longer accept products with average quality of related services. For a company that wants to stay in the market and achieve profitability, the only solution is moving towards a complete product package type goods-services. Associated services are thus an indicator of quality and the best customer loyalty insurance policy, there is a close relationship between the quality of services provided by a firm, customer satisfaction and company profitability.

    2017-03-01

    Drying is one of conventional processes to enhance shelf life of onion. However, the active compounds such as vitamin and anthocyanin (represented in red color), degraded due to the introduction of heat during the process. The objective of this research was to evaluate thiamine content as well as color in onion drying under different temperature. As an indicator, the thiamine and color was observed every 30 minutes for 2 hours. Results showed that thiamine content and color were sensitvely influenced by the temperature change. For example, at 50°C for 2 hours drying process, the thiamine degradation was 55.37 %, whereas, at 60°C with same drying time, the degradation was 74.01%. The quality degradation also increased by prolonging drying time.

    The U.S. Geological Survey's Albuquerque Seismological Laboratory (ASL) has several initiatives underway to enhance and track the quality of data produced from ASL seismic stations and to improve communication about data problems to the user community. The Data Quality Analyzer (DQA) is one such development and is designed to characterize seismic station data quality in a quantitative and automated manner. The DQA consists of a metric calculator, a PostgreSQL database, and a Web interface: The metric calculator, SEEDscan, is a Java application that reads and processes miniSEED data and generates metrics based on a configuration file. SEEDscan compares hashes of metadata and data to detect changes in either and performs subsequent recalculations as needed. This ensures that the metric values are up to date and accurate. SEEDscan can be run as a scheduled task or on demand. The PostgreSQL database acts as a central hub where metric values and limited station descriptions are stored at the channel level with one-day granularity. The Web interface dynamically loads station data from the database and allows the user to make requests for time periods of interest, review specific networks and stations, plot metrics as a function of time, and adjust the contribution of various metrics to the overall quality grade of the station. The quantification of data quality is based on the evaluation of various metrics (e.g., timing quality, daily noise levels relative to long-term noise models, and comparisons between broadband data and event synthetics). Users may select which metrics contribute to the assessment and those metrics are aggregated into a "grade" for each station. The DQA is being actively used for station diagnostics and evaluation based on the completed metrics (availability, gap count, timing quality, deviation from a global noise model, deviation from a station noise model, coherence between co-located sensors, and comparison between broadband data and synthetics

    1989-01-01

    The prime focus of the CANDU concept (natural uranium fuelled-heavy water moderated reactor) from the beginning has economy, heavy water losses and radiation exposures also were strong incentives for ensuring good design and reliable equipment. It was necessary to depart from previously accepted commercial standards and to adopt those now accepted in industries providing quality products. Also, through feedback from operating experience and specific design and development programs to eliminate problems and improve performance, CANDU has evolved into today's successful product and one from which future products will readily evolve. Many lessons have been learned along the way. On the one hand, short cuts of failures to understand basic requirements have been costly. On the other hand, sound engineering and quality equipment have yielded impressive economic advantages through superior performance and the avoidance of failures and their consequential costs. The achievement of lifetime economical performance demands quality products, good operation and good maintenance. This paper describes some of the basic approaches leading to high CANDU station reliability and overall excellent performance, particularly where difficulties have had to be overcome. Specific improvements in CANDU design and in such CANDU equipment as heat transport pumps, steam generators, valves, the reactor, fuelling machines and station computers, are described. The need for close collaboration among designers, nuclear laboratories, constructors, operators and industry is discussed. This paper has reviewed some of the key components in the CANDU system as a means of indicating the overall effort that is required to provide good designs and highly reliable equipment. This has required a significant investment in people and funding which has handsomely paid off in the excellent performance of CANDU stations.

    Due to a variety of factors to affect the herb quality, the existing quality management model is unable to evaluate the process control. The development of the concept of "quality marker" (Q-marker) lays basis for establishing an independent process quality control system for herbal products. To ensure the highest degree of safety, effectiveness and quality process control of herbal products, it is aimed to establish a quality transitivity and traceability system of quality and process control from raw materials to finished herbal products. Based on the key issues and challenges of quality assessment, the current status of quality and process controls from raw materials to herbal medicinal products listed in Pharmacopoeia were analyzed and the research models including discovery and identification of Q-markers, analysis and quality management of risk evaluation were designed. Authors introduced a few new technologies and methodologies, such as DNA barcoding, chromatographic technologies, fingerprint analysis, chemical markers, bio-responses, risk management and solution for quality process control. The quality and process control models for herbal medicinal products were proposed and the transitivity and traceability system from raw materials to the finished products was constructed to improve the herbal quality from the entire supply and production chain. The transitivity and traceability system has been established based on quality markers, especially on how to control the production process under Good Engineering Practices, as well as to implement the risk management for quality and process control in herbal medicine production.

    Currently, companies active in the design of high-tech products are confronted with a number of, often conflicting, challenges. Not only do they have to develop increasingly complex products in ever-shorter amounts of time but they also have to produce them cheaply for the local as well as global markets. In order to manage these conflicting trends adequately, as this paper will demonstrate, companies need to have high quality information at the right moment and at the right location. This serves as the motivation of this paper in which various databases within the product life cycle are examined. Due to the fact that unanticipated information plays a more and more dominant role, especially in highly innovative business processes, we focus our attention on textual databases since textual databases offer the best possibility to handle unanticipated free-formatted information. Also their treatment in the literature has thus far been scant. As will be demonstrated in this paper these databases have a huge potential for valuable information. Further, an analysis tool, data mining that could be used to analyse these textual databases so that we could extract information from them quickly and hence be able to access them at the right time when needed, is presented. We also highlight some of the difficulties faced when analyzing textual databases. Thus with the right information from the textual databases and the tools to deliver this information at the right time companies, would definitely be able to shorten development times and hence gain a competitive edge

    2012-01-01

    Assessing product-image quality is important in the context of online shopping. A high quality image that conveys more information about a product can boost the buyer's confidence and can get more attention. However, the notion of image quality for product-images is not the same as that in other domains. The perception of quality of product-images depends not only on various photographic quality features but also on various high level features such as clarity of the foreground or goodness of the background etc. In this paper, we define a notion of product-image quality based on various such features. We conduct a crowd-sourced experiment to collect user judgments on thousands of eBay's images. We formulate a multi-class classification problem for modeling image quality by classifying images into good, fair and poor quality based on the guided perceptual notions from the judges. We also conduct experiments with regression using average crowd-sourced human judgments as target. We compute a pseudo-regression score with expected average of predicted classes and also compute a score from the regression technique. We design many experiments with various sampling and voting schemes with crowd-sourced data and construct various experimental image quality models. Most of our models have reasonable accuracies (greater or equal to 70%) on test data set. We observe that our computed image quality score has a high (0.66) rank correlation with average votes from the crowd sourced human judgments.

    Full Text Available The objective of this paper was to investigate possibility of using multivariate statistical process control in analysing cheese quality parameters. Two cheese types (white brined cheeses and soft cheese from ultra-filtered milk were selected and analysed for several quality parameters such as dry matter, milk fat, protein contents, pH, NaCl, fat in dry matter and moisture in non-fat solids. The obtained results showed significant variations for most of the quality characteristics which were examined among the two types of cheese. The only stable parameter in both types of cheese was moisture in non-fat solids. All of the other cheese quality characteristics were characterized above or below control limits for most of the samples. Such results indicated a high instability and variations within cheese production. Although the use of statistical process control is not mandatory in the dairy industry, it might provide benefits to organizations in improving quality control of dairy products.

    Full Text Available Quality became the management imperative in the last time and will continue to be the key to success in the future. We often see the words “quality first”, and demands for quality invade every sphere of activity, from the motor vehicles we drive, to the domestic appliances we use, the food we eat and, of course, the products and services we import and export. Quality represents the goal of every business and it is focused on the customer. Satisfying the requirements of the customer is a dynamic activity: both customers and their needs are changing continuous and the suppliers have to recognize this. When it comes to international trade, no exporting country can afford to compromise on quality. The current global economic climate calls for export marketing and promotion efforts with assurances of superior and consistent quality in products and services, rather associated with lower prices.

    2009-04-01

    Full Text Available Nowadays, the main goal for modern horticultural production is the increase of quality. Furthermore, in consideration of the new consumer demand, always more attracted by a diet based on a larger consumption of fruit and vegetables without risks of pesticides residues and with increased nutritional value, new important features in addition to the traditional quality attributes are now requested. For a program of qualification and valorisation of modern horticultural productions, it is fundamental a study of the major quality determinants organized by following a heuristic approache useful to identify the contribution of each factor in defining the quality of the product. The genetic knowledge applied to all available techniques useful for the creation of new genetic variability surely represent the most important starting point for the release of new varieties with increased nutritional quality without limitation in plant productivity. About agronomic practices, new opportunities are offered by the sustainable management of the production factors able to improve the plant-environment interaction, to well address the reduction of inputs needed for the production, and finally to induce specific stress conditions able to promote higher quality at reduced inputs. Much more attention is also addressed to the post-harvest technologies, this because of the increased needs to guarantee the preservation of the high quality obtained in the field until the consumer use. Taking in account such complexity of the horticultural production systems and examples of some major model crops, an outlook of the main determinants and potential valorisation of high quality horticultural products are attempted.

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

    In response to concerns raised about the quality of parenteral vancomycin products, the U.S. Food and Drug Administration (FDA) is investigating the product quality of all FDA-approved parenteral vancomycin products available in the United States. Product quality was evaluated independently at two FDA Office of Testing and Research (FDA-OTR) sites. In the next phase of the investigation, being done in collaboration with the National Institute of Allergy and Infectious Diseases, the in vivo activity of these products will be evaluated in an appropriate animal model. This paper summarizes results of the FDA investigation completed thus far. One site used a validated ultrahigh-pressure liquid chromatography method (OTR-UPLC), and the second site used the high-performance liquid chromatography (HPLC) method for related substances provided in the British Pharmacopeia (BP) monograph for vancomycin intravenous infusion. Similar results were obtained by the two FDA-OTR laboratories using two different analytical methods. The products tested had 90 to 95% vancomycin B (active component of vancomycin) by the BP-HPLC method and 89 to 94% vancomycin by OTR-UPLC methods. Total impurities were 5 to 10% by BP-HPLC and 6 to 11% by OTR-UPLC methods. No single impurity was >2.0%, and the CDP-1 level was ≤ 2.0% across all products. Some variability in impurity profiles of the various products was observed. No adverse product quality issues were identified with the six U.S. vancomycin parenteral products. The quality parameters of all parenteral vancomycin products tested surpassed the United States Pharmacopeia acceptance criteria. Additional testing will characterize in vivo performance characteristics of these products.

    Turner, Michael J

    2012-02-01

    OBJECTIVE: To examine the use of quality control performance charts to analyze cesarean rates nationally. METHODS: Information on cesarean rates was obtained for all 19 Irish maternity hospitals receiving state funding in 2009. All women who underwent cesarean delivery of a live or stillborn infant weighing 500 g or more between January 1 and December 31 were included. Deliveries were classified as elective or emergency. Individual hospitals were not identified in the analysis. RESULTS: The mean rates per hospital of elective and emergency cesarean were 12.9+\\/-2.6% (n=9337) and 13.8+\\/-3.0% (n=9989), respectively-giving an overall mean rate of 26.7+\\/-4.2% (n=19326) per hospital. Cesarean rates were normally distributed. Using a quality control performance chart with a cutoff 2 standard deviations from the mean, 1 hospital was above the normal range for both total and elective cesareans, indicating that its pre-labor obstetric practices warrant clinical review. Another hospital had a mean emergency cesarean rate above the normal range, indicating that its labor ward practices warrant review. CONCLUSION: Quality control performance charts can be used to analyze cesarean rates nationally and, thus, to identify hospitals at which obstetric practices should be reviewed.

    1998-10-01

    This work studies visual quality control in ceramics industry. In tile manufacturing, it is important that in each set of tiles, every single tile looks similar. For example, the tiles should have similar color and texture. Our goal is to design a machine vision system that can estimate the sufficient similarity or same appearance to the human eye. Currently, the estimation is usually done by human vision. Differing from other approaches our aim is to use accurate spectral representation of color, and we are comparing spectral features to the RGB color features. A laboratory system for color measurement is built. Experimentations with five classes of brown tiles are presented. We use chromaticity RGB features and several spectral features for classification with the k-NN classifier and with a neural network, called Self-Organizing Map. We can classify many of the tiles but there are several problems that need further investigations: larger training and test sets are needed, illuminations effects must be studied further, and more suitable spectral features are needed with more sophisticated classifiers. It is also interesting to develop further the neural approach.

    ENGLISH ABSTRACT:The quality of the raw material and supplied product from suppliers plays a critical role in the quality of the final product. It has become the norm that vehicle manufacturers require their suppliers to measure product quality and service with a product audit method. Measuring quality of product is emphasised by QS9000 VDA6.5 and ISO/TS16949. From a competitive standpoint, and also to see continuous improvement in business, companies need to monitor their suppliers’ performance. Quality and delivery are two very important indicators of supplier performance. This paper presents a statistical method for measuring the quality of supplied product. This method allocates different weights to variables and attributes characteristics. Moreover, following normal distribution, the tolerance zone is divided to three regions with different scores. Therefore, the quality of suppliers’ products can be monitored based on the Product Quality Audit Score (PQAS. However, this method may be employed for organisations to monitor their raw material, work-in-process parts, and final product. It can be an indicator to monitor supplier quality behaviour.

    Full Text Available We study an entrant firm’s product quality choice and the price competition arising between the entrant and the incumbent firm. We show that the entrant firm should introduce a relatively higher (lower quality than the incumbent firm when the consumers’ valuation for quality is sufficiently large (small. We also study how the incumbent firm modifies its price in response to the ensuing price competition. We find that the incumbent firm should decrease its price. We also profile how the incumbent firm’s price non-linearly depends on consumers’ valuation for quality.

    Full Text Available In the last few years several definitions of “soil quality” have been advanced, but among them the most appreciated is “the ability of soils to interact with the ecosystem in order to maintain the biological productivity, the environmental quality and to promote animal and vegetal health” as defined by Doran and Parkin in 1994. Many researchers place more emphasis on its conceptual meaning for land planning and farm management, while others consider that definition to be worth nothing in order to understand soil properties and the concept of soil quality looks like the concept of “to be suitable for”. For this reason a definition of “soil use” is needed. The food quality is characterized by several properties: the healthiness and the nutritional value, the amount of the production, the typicalness and organoleptic properties, etc.. A lot of these properties depend on environmental quality and, in particular, on soil quality. In fact soil represents the natural substrate for growth and productivity of most of the plants that live on the Hearth because they get all the essential nutritional elements from it for their own development; consequently each nutritional element present into the soil as bioavailable form for the plants is potentially destined to entry in the animal (and human food chain. In the quality process of food productive process it will be important to assure the best soil quality as possible, without any unwanted element (which will not be discussed in this note and with the right amount of fertility elements in order to guarantee the best production. In this paper the relationships between soil quality, soil biodiversity and crop sustainability will be discussed. Finally the concept of soil “biota” as nodal point for the environment regulation and the application of the indicators for soil quality will be discussed.

    Recent trends of assimilating water well records into statewide databases provide a new opportunity for evaluating spatial dynamics of groundwater quality and quantity. However, these datasets are scarcely rigorously analyzed to address larger scientific problems because they are of lower quality and massive. We develop an approach for utilizing well databases to analyze physical and geochemical aspects of groundwater systems, and apply it to a multiscale investigation of the sources and dynamics of chloride (Cl - ) in the near-surface groundwater of the Lower Peninsula of Michigan. Nearly 500,000 static water levels (SWLs) were critically evaluated, extracted, and analyzed to delineate long-term, average groundwater flow patterns using a nonstationary kriging technique at the basin-scale (i.e., across the entire peninsula). Two regions identified as major basin-scale discharge zones-the Michigan and Saginaw Lowlands-were further analyzed with regional- and local-scale SWL models. Groundwater valleys ("discharge" zones) and mounds ("recharge" zones) were identified for all models, and the proportions of wells with elevated Cl - concentrations in each zone were calculated, visualized, and compared. Concentrations in discharge zones, where groundwater is expected to flow primarily upwards, are consistently and significantly higher than those in recharge zones. A synoptic sampling campaign in the Michigan Lowlands revealed concentrations generally increase with depth, a trend noted in previous studies of the Saginaw Lowlands. These strong, consistent SWL and Cl - distribution patterns across multiple scales suggest that a deep source (i.e., Michigan brines) is the primary cause for the elevated chloride concentrations observed in discharge areas across the peninsula. © 2017, National Ground Water Association.

    Coffee is an important commodity and a very popular beverage around the world. Its economic value as well as beverage quality are strongly dependent of the quality of beans. The presence of defective beans in coffee blends has caused a negative impact on the beverage Global Quality (GQ) assessed by cupping tests. The main defective beans observed in the productive chain has been those Blacks, Greens and Sours (BGS). Chemical composition of BGS has a damaging impact on beverage GQ. That is why analytical tools are needed for monitoring and controlling the GQ in coffee agro-industry. Near Infrared Spectroscopy (NIRS) has been successfully applied for assessment of coffee quality. Another potential technique for direct, clean and fast measurement of coffee GQ is Laser Induced Breakdown Spectroscopy (LIBS). Elements and diatomic molecules commonly present in organic compounds (structure) can be assessed by using LIBS. In this article is reported an evaluation of LIBS for the main interferents of GQ (BGS defects). Results confirm the great potential of LIBS for discriminating good beans from those with BGS defects by using emission lines of C, CN, C2 and N. Most importantly, some emission lines presented strong linear correlation (r > 0.9) with NIRS absorption bands assigned to proteins, lipids, sugar and carboxylic acids, suggesting LIBS potential to estimate these compounds in unroasted and ground coffee samples.

    2014-10-01

    An online visual analytical system based on Java Web and WebGIS for air quality data for Shanghai Municipality was designed and implemented to quantitatively analyze and qualitatively visualize air quality data. By analyzing the architecture of WebGIS and Java Web, we firstly designed the overall scheme for system architecture, then put forward the software and hardware environment and also determined the main function modules for the system. The visual system was ultimately established with the DIV + CSS layout method combined with JSP, JavaScript, and some other computer programming languages based on the Java programming environment. Moreover, Struts, Spring, and Hibernate frameworks (SSH) were integrated in the system for the purpose of easy maintenance and expansion. To provide mapping service and spatial analysis functions, we selected ArcGIS for Server as the GIS server. We also used Oracle database and ESRI file geodatabase to store spatial data and non-spatial data in order to ensure the data security. In addition, the response data from the Web server are resampled to implement rapid visualization through the browser. The experimental successes indicate that this system can quickly respond to user's requests, and efficiently return the accurate processing results.

Up until now, re-using traditional static analyses for SPLs was virtually intractable, as it required programmers to generate and analyze all products individually...... changing a single line of code. Through experiments using three static analyses applied to four Java-based product lines, we were able to show that our approach produces correct results and outperforms the traditional approach by several orders of magnitude........ In this work, however, we show how an important class of existing inter-procedural static analyses can be transparently lifted to SPLs. Without requiring programmers to change a single line of code, our approach SPLLIFT automatically converts any analysis formulated for traditional programs within the popular...

    2015-11-23

    Image analysis software is an essential tool used in neuroscience and neural engineering to evaluate changes in neuronal structure following extracellular stimuli. Both manual and automated methods in current use are severely inadequate at detecting and quantifying changes in neuronal morphology when the images analyzed have a low signal-to-noise ratio (SNR). This inadequacy derives from the fact that these methods often include data from non-neuronal structures or artifacts by simply tracing pixels with high intensity. In this paper, we describe Neuron Image Analyzer (NIA), a novel algorithm that overcomes these inadequacies by employing Laplacian of Gaussian filter and graphical models (i.e., Hidden Markov Model, Fully Connected Chain Model) to specifically extract relational pixel information corresponding to neuronal structures (i.e., soma, neurite). As such, NIA that is based on vector representation is less likely to detect false signals (i.e., non-neuronal structures) or generate artifact signals (i.e., deformation of original structures) than current image analysis algorithms that are based on raster representation. We demonstrate that NIA enables precise quantification of neuronal processes (e.g., length and orientation of neurites) in low quality images with a significant increase in the accuracy of detecting neuronal changes post-stimulation.

    2001-01-01

    A high throughput Pulse Height Analyzer system for synchrotron-based applications requiring high resolution, high processing speed and low dead time has been developed. The system is comprised of a 120ns 12-bit nuclear quality Analog to Digital converter with a self-adaptive fast peak detector-stretcher and a custom-made fast histogramming memory module that records and processes the digitized data. The histogramming module is packaged in a VME or VXI compatible interface. Data is transferred through a fast optical link from the memory interface to a computer. A dedicated data acquisition program matches the hardware characteristics of the histogramming memory module. The data acquisition system allows for two data collection modes: ''standard'' data acquisition mode where the data is accumulated and read in synchronization with an external trigger and ''live'' data acquisition mode where the system operates as a standard Pulse Height Analyzer. The acquisition, standard or live, can be performed on several channels simultaneously. A two-channel prototype has been demonstrated at the Stanford Synchrotron Radiation Laboratory accelerator in conjunction with an X-ray Fluorescence Absorption Spectroscopy experiment. A detailed description of the entire system is given and experimental data is shown

    With natural resource scarcity and environmental protection, the use of renewable energy has become a promise for offering clean and plentiful energy. Photovoltaic (PV) solar cell is one of the emerging renewable energy applications; however, it suffers a large difficulty in high production cost with low conversion efficiency currently. Hence, an urgent pressure to upgrade technology and to formulate product strategy is evident in the solar cell power industry. In order to prosper PV silicone solar cell power industry, the paper develops a conceptual model, which is composed of a fuzzy analytic network process with interpretive structural modeling and benefits, opportunities, costs and risks, to help analyze suitable strategic products. The empirical study shows that the conceptual model can effectively and precisely handle such a complicated problem and can lead to an outstanding performance result. (author)

    2001-01-01

    A study group of 376 Clinton Sand wells in Ohio provided data to determine the historic frequency of the problem of abnormal production declines in stripper gas wells and the causes of the abnormal production decline. Analysis of the historic frequency of the problem indicates over 70% of the wells experienced abnormal production decline. The most frequently occurring causes of abnormal production declines were determined to be fluid accumulation (46%), gas gathering restrictions (24%), and mechanical failures (23%). Data collection forms and decision trees were developed to cost-effectively diagnose the abnormal production declines and suggest corrective action. The decision trees and data collection sheets were incorporated into a procedure guide to provide stripper gas well operators with a methodology to analyze and correct abnormal production declines. The systematic methodologies and techniques developed should increase the efficiency of problem well assessment and implementation of solutions for stripper gas wells. This eight quarterly technical progress report provides a summary of the deliverables completed to date, including the results of the remediations, the procedure guide, and the technology transfer. Due to the successful results of the study to date and the efficiency of the methodology development, two to three additional wells will be selected for remediation for inclusion into the study. The results of the additional remediations will be included in the final report

    Aggregate Production Planning (APP) is a medium-term planning which is concerned with the lowest-cost method of production planning to meet customers' requirements and to satisfy fluctuating demand over a planning time horizon. APP problem has been studied widely since it was introduced and formulated in 1950s. However, in several conducted studies in the APP area, most of the researchers have concentrated on some common objectives such as minimization of cost, fluctuation in the number of workers, and inventory level. Specifically, maintaining quality at the desirable level as an objective while minimizing cost has not been considered in previous studies. In this study, an attempt has been made to develop a multi-objective mixed integer linear programming model that serves those companies aiming to incur the minimum level of operational cost while maintaining quality at an acceptable level. In order to obtain the solution to the multi-objective model, the Fuzzy Goal Programming approach and max-min operator of Bellman-Zadeh were applied to the model. At the final step, IBM ILOG CPLEX Optimization Studio software was used to obtain the experimental results based on the data collected from an automotive parts manufacturing company. The results show that incorporating quality in the model imposes some costs, however a trade-off should be done between the cost resulting from producing products with higher quality and the cost that the firm may incur due to customer dissatisfaction and sale losses.

    Full Text Available The supply chain management, postponement and demand management functions are of strategic importance to the economic success of organizations because they influence the production process, when viewed in isolation and empirically may hinder understanding of their behavior. The aim of this paper is to analyze the influence of the postponement in an enterprise production system with make-to-stock and with seasonal demand. The research method used was a case study, the instruments of data collection were semi-structured interviews, documentary analysis and site visits. This research is restricted to analysis of the influence that different levels of delay and the company's position in the supply chain have on the practice of demand management in the productive segment graphic, product spiral notebook and also in relation to geographical focus (region of the state São Paulo, in which it will seek to interview the managers and directors. As a way to support the research on the analysis of case study and the final considerations will be discussed the following issues: supply chain management, postponement, demand management and production system make-to-stock. The demand management can be understood as a practice that allows you to manage and coordinate the supply chain in reverse, i.e. the consumer to the supplier, in which consumers trigger actions for the supply of products can make the process more efficient. The purpose of managing the supply chain is able to allow the addition of value, exceeding the expectations of consumers, it is necessary to develop a relationship with suppliers and customers win-win. The postponement strategy must fit the characteristics of the turbulent environment within the markets along with demands that require variety of customized products and services and reasonable costs, aiming to support decision making. The postponement of time can be a way to soften the increase in inventory of finished product in the company

    Full Text Available Beer business industry is one of the most profitable agro-processing industries in the country. It has increased by expanding local and international market. There are 80 small and large beer factories that have their activity in Albania. The leading domestic beer manufacturers are: "Stela" beer, “Tirana” beer, “Korca” beer, “Kaon” beer, “Norga” beer, etc. They have invested millions of euros in terms of improving the quality of their production. Stela beer was the fi rst private beer active in the Albanian market. Its factory production founders of Stela beer responded to the market by investing in the development of technology, modern equipment and science. Stela beer processing and production systems have been improved continuously. The investments today are at around 20 million dollars. The factory has a considerable number of employees and a production capacity of around 250,000 hl per year. This article uses information obtained for beer production during the period 2003-2016. Through nonparametric mathematical model Dea, the impact of production factors such as investment, advertising, expenses, capital and number of employees in the production of beer during the study period is analyzed. The analysis showed that the best years or more efficient years in the use of the quantity of inputs for the period 2003-2016 are 2007, 2014 and 2015. The years 2003, 2010 and 2012 are less efficient by Dea analysis. The study also showed the best possible combinations of inputs improving the efficiency of inefficient years in the Stela Beer production.

    The use of Residual Gas Analyzers (RGAs) during irradiation experiments can provide valuable information when incorporated into experimental end-stations. The instruments can track the volatilization products of beam-sensitive materials, which may ultimately aid researchers in selecting appropriate flux values for conducting experiments. Furthermore, the type of gaseous species released during an irradiation can be monitored directly, which may lead to new insights into the radiolysis and/or heating mechanisms responsible for gas evolution. A survey of several classes of materials exposed to extremes in particle flux is presented to show how RGA instrumentation can be incorporated to qualitatively assess ion-solid interactions in a variety of fields.

    2016-04-01

    Full Text Available A modern market economy is an exceedingly complex, infinite-dimensional, stochastic dynamical system. The failure of mainstream economists to characterize its dynamics may well be due to its intractability. This paper argues that the characterization of its dynamics becomes almost trivial when it is analyzed from the perspective of information production. Whether its Jacobian matrix is specifiable or not, a Lyapunov spectrum can be constructed from which the potential Kolmogorov-Sinai or Shannon entropy can be assessed. However, a self-organized equilibrium must first obtain, and for that a suitable policy must be operational.

    Full Text Available This paper aims to provide a thorough analysis on the application of TRIZ in improving the quality of canned food production. TRIZ tools such as engineering systems analysis, function analysis, cause and effect chain analysis, By-separation model and 40 Inventive Principles are applied in order to discover some feasible and elegant solutions to alleviate the problem. Findings revealed that the rejected canned products on the conveyor belt will be isolated or picked up with other good condition canned products which are lined up very closely to the rejected cans; though the visioning system is able detect the fault printing on the canned product. The main root cause is that the rejected canned product is picked up with other canned products in good condition because all cans are lined up on the belt and are very close to each other or having no gaps between the cans. Conversely, all cans on the conveyor belts are required to be very close to each other to avoid collisions that may damage the cans. The root cause is solved by applying function analysis, By-separation tool and Inventive Principles. Therefore, it can be concluded that TRIZ is a powerful tool in inventive problem solving.

    2012-09-01

    Full Text Available Abstract Background Health-related quality of life (HRQL has become an increasingly important outcome parameter in clinical trials and epidemiological research. HRQL scores are typically bounded at both ends of the scale and often highly skewed. Several regression techniques have been proposed to model such data in cross-sectional studies, however, methods applicable in longitudinal research are less well researched. This study examined the use of beta regression models for analyzing longitudinal HRQL data using two empirical examples with distributional features typically encountered in practice. Methods We used SF-6D utility data from a German older age cohort study and stroke-specific HRQL data from a randomized controlled trial. We described the conceptual differences between mixed and marginal beta regression models and compared both models to the commonly used linear mixed model in terms of overall fit and predictive accuracy. Results At any measurement time, the beta distribution fitted the SF-6D utility data and stroke-specific HRQL data better than the normal distribution. The mixed beta model showed better likelihood-based fit statistics than the linear mixed model and respected the boundedness of the outcome variable. However, it tended to underestimate the true mean at the upper part of the distribution. Adjusted group means from marginal beta model and linear mixed model were nearly identical but differences could be observed with respect to standard errors. Conclusions Understanding the conceptual differences between mixed and marginal beta regression models is important for their proper use in the analysis of longitudinal HRQL data. Beta regression fits the typical distribution of HRQL data better than linear mixed models, however, if focus is on estimating group mean scores rather than making individual predictions, the two methods might not differ substantially.

    The Sperm Quality Analyzer (SQA-Vp) was evaluated for assessing concentration and motility of porcine semen. Both fresh and diluted semen from 50 different boars from a commercial artificial insemination (AI) centre were investigated. For the fresh ejaculate, the concentration obtained with SQA-Vp was compared with a photometer and a haemocytometer. For the diluted samples, the concentration and motility were compared with computer assisted semen analysis (CASA) and visual sperm analysis. The agreement between methods was studied with Bland-Altman plots and the repeatability with coefficient of variation (CV) as well as Bland-Altman plots. The sperm concentration (x10(6)/ml) obtained with SQA-Vp (379.3 ± 134.9) for fresh ejaculates agreed well with concentration by the photometer (447.2 ± 154.2; difference= -67.9 x 10(6)/ml; difference + 2SD = 55.3 x 10(6)/ml; difference - 2SD = -191.1 x 10(6)/ml) and with the haemocytometer (332.8 ± 141.11; d = 92.8; d + 2SD = 448.6; d - 2SD = -263). For diluted semen, the agreement between the concentration (x10(6)/ml) assessed with SQA-Vp (20.4 ± 4.3) was good with CASA (23.2 ± 5.8; d = -2.8; d + 2SD = 6.2; d - 2 SD = -11.8) but poor with the haemocytometer (18.8 ± 5.0; d = 1.6; d+ 2SD = 12.2; d - 2SD = -9). The % motile spermatozoa assessed by SQA-Vp (65.8 ± 10.0) in diluted semen agreed well with CASA (72.2 ± 13.7; d = -6.4; d+ 2SD = 20; d - 2SD = -32.8) and with visual assessment (64.1 ± 11.6; d = 1.7; d+ 2SD = 30.9; d - 2SD = -27.5). The SQA-Vp showed a good repeatability (CV; repeatability coefficient) for measuring the concentration of both fresh (3.9%; d = 10.7; d + 2SD = 30.9; d - 2SD = -9.5) and diluted semen (2.6%; d = 1.0; d + 2SD = 2.38; d - 2SD = -0.42) and for motility (3.2%; d = 0.9; d + 2SD = 8.5; d - 2SD = -6.7). The mean SQA-Vp values fell between the other methods' results for both fresh and diluted semen. Moreover the repeatability was acceptable. Therefore SQA-Vp can be used as a valid device for

    It is generally recognized that careful implementation of ecological monitoring should be provided at hazardous production facilities continuously to protect the surrounding environment as well as health and safety of employees. However, the existing devices may not be able to control the environmental situation uninterruptedly due to their technical characteristics or measurement methods. Developed by The Mining University Plasma Research Group ultra-compact photoionization analyzer is proposed as innovative equipment which creates the basis for a new measuring approach. The general operating principle is based on the patented method of stabilization of electric parameters - CES (Collisional Electron Spectroscopy). During the operation at the atmospheric pressure, the vacuum ultraviolet (VUV) photoionization sensor measures the energy of electrons produced by means of ionization with the resonance photons whose wavelength is situated in the VUV. A special software tool was developed to obtain the second-order derivative of the I-U characteristics, taken by the VUV sensor, to construct the characteristic electrons energy spectra. The portable analyzer with a unique set of parameters such as small size (10*10*1 mm), low cost, a wide range of recognizable molecules, great measurement accuracy at the atmospheric pressure can be effectively used both for rapid testing of air pollution load and the study of noxious factors that influence oil and gas industry employees.

    Scarce information exists about quality requirements and objective evaluation of performance of large veterinary bench top hematology analyzers. The study was aimed at comparing the observed total error (TEobs ) derived from meta-analysis of published method validation data to the total allowable error (TEa ) for veterinary hematology variables in small animals based on experts' opinions. Ideally, TEobs should be hematology analyzers (ADVIA 2120; Sysmex XT2000iV, and CellDyn 3500) was calculated based on method validation studies published between 2005 and 2013 (n = 4). The percent TEobs = 2 * CV (%) + bias (%). The CV was derived from published studies except for the ADVIA 2120 (internal data), and bias was estimated from the regression equation. A total of 41 veterinary experts (19 diplomates, 8 residents, 10 postgraduate students, 4 anonymous specialists) responded. The proposed range of TEa was wide, but generally ≤ 20%. The TEobs was < TEa for all variables and analyzers except for canine and feline HGB (high bias, low CV) and platelet counts (high bias, high CV). Overall, veterinary bench top analyzers fulfilled experts' requirements except for HGB due to method-related bias, and platelet counts due to known preanalytic/analytic issues. © 2016 American Society for Veterinary Clinical Pathology.

    As the subject of water quality in the European Union is becoming all the more important, public awareness is of significant importance in exploring ways towards the implementation of better water quality. Over the last decade, significant steps towards this direction have been employed in EU, such as Directive 2008/105/EC and Directive 2013/39/EU and Groundwater Directive and Decision 2015/495. What has been suggested so far is that public participation and information levels are relatively low in some EU countries. This paper focuses on providing a review on economic valuation in EU and in regions with degradated waters by applying geospatial techniques. Overall, it is shown that public awareness and information levels are crucial in better assessing the issues that arise due to water quality, and help better implement EU legislation.

    Thanks to the rapid increase of the interest in the quality control of the General X-ray systems, this research proposes the direction of the quality control through comparing and inspecting the actual condition of the respective quality control in the Clinic, the educational institution and the hospital. The subjects of the investigation are diagnostic radiation equipment's in the clinic, the educational institution and the hospital around the capital. A test of kVp, mR/mAs out put test and reproducibility of the exposure dose, half value layer, an accordance between the light field and the beam alignment test, and lastly reproducibility of the exposure time. Then the mean difference of the percentage, the CV (Coefficient of Variation, CV) and the attenuated curve which are respectively resulted from the above tests are computed. After that we have evaluated the values according to the regulations on the Diagnostic Radiation Equipment Safety Administration regulations. In the case of the clinic and the educational institution, there were 22 general X-ray devices. And 18.2% of the kVp test, 13.6% of the reproducibility of exposure dose test, 9.1% of the mR/mAs out put test, and 13.6% of the HVL (Half Value Layer) test appeared to be improper. In the case of the hospital, however, there were 28 devices. And 7.1% of the reproducibility of exposure dose, 7.1% of the difference in the light field/ beam alignment, and 7.1% of the reproducibility of the exposure time appeared to be improper. According to the investigation, the hospital's quality control condition is better than the condition in the clinic and the educational institution. The quality control condition of the general X-ray devices in the clinic is unsatisfactory compared to the hospital. Thus, it is considered that realizing the importance of the quality control is necessary.

    Full Text Available OBJECTIVE: The aim of this study was to evaluate the quality of meals consumed by workers from São Paulo according to eating location. METHODS: This cross-sectional study used the 24-hour recall to collect dietary data from 815 workers, including where the meal was consumed, and then grouped the meals by eating location: home, workplace cafeteria, and restaurant. Meal quality was assessed according to energy content and density, fiber density, and proportion of macronutrients, 10 food groups, and from sugar-sweetened beverages. These indicators and their respective eating locations were then included in linear regression models adjusted for gender, age, and education level. RESULTS: Meals consumed at workplace cafeterias had lower energy density, higher fiber density, and higher proportions of vegetables, fruits, and beans than those consumed at home. However, away-from-home meals contain more sugars, sweets, fats, and oils. CONCLUSION: Eating location influences diet quality, so dietary surveys should assess meals consumed away from home more thoroughly since meal quality varies greatly by food service.

    Sufficient quantities of quality air and controlled, unidirectional flow are important elements in providing a safe building environment for operating rooms. To make dynamic assessments of an operating room environment, a validated method of testing the multiple factors influencing the air quality in health care settings needed to be constructed. These include the following: temperature, humidity, particle load, number of microbial contaminants, pressurization, air velocity, and air distribution. The team developed the name environmental quality indicators (EQIs) to describe the overall air quality based on the actual measurements of these properties taken during the mock surgical procedures. These indicators were measured at 3 different hospitals during mock surgical procedures to simulate actual operating room conditions. EQIs included microbial assessments at the operating table and the back instrument table and real-time analysis of particle counts at 9 different defined locations in the operating suites. Air velocities were measured at the face of the supply diffusers, at the sterile field, at the back table, and at a return grille. The testing protocol provided consistent and comparable measurements of air quality indicators between institutions. At 20 air changes per hour (ACH), and an average temperature of 66.3°F, the median of the microbial contaminants for the 3 operating room sites ranged from 3-22 colony forming units (CFU)/m 3 at the sterile field and 5-27 CFU/m 3 at the back table. At 20 ACH, the median levels of the 0.5-µm particles at the 3 sites were 85,079, 85,325, and 912,232 in particles per cubic meter, with a predictable increase in particle load in the non-high-efficiency particulate air-filtered operating room site. Using a comparison with cleanroom standards, the microbial and particle counts in all 3 operating rooms were equivalent to International Organization for Standardization classifications 7 and 8 during the mock surgical

    The main CryoSat mission objectives are to measure the regional and basin-scale changes in the thickness of the sea-ice and, in the elevation of the ice sheets and mountain glaciers. Beside its ice-monitoring objective, CryoSat also provides valuable observations for the oceanographic community. The CryoSat data are processed by ESA both over the ocean and ice surfaces with two independent processors. These data need to be routinely Quality-Controlled and thoroughly Validated (QCV). Based on the QCV outcomes from ESA multi-national partners and the feedback from the scientific community, the data products continuously evolve in order to accommodate a wide range of users over the Sea ice, the Land Ice and the Ocean domains. The main objectives of this paper are to give an overview of main CryoSat QCV results and product improvements; as well as to present the processing algorithm upgrades being implemented for future ice and ocean Baselines.

    2018-02-09

    During manufacturing of a lyophilized drug product, operator errors in product handling during loading of product filled vials onto the lyophilizer can lead to a seemingly cosmetic defect which can impact certain critical quality attributes of finished product. In this study, filling of a formulated monoclonal antibody in vials was performed using a peristaltic pump filling unit, and subsequently, the product was lyophilized. After lyophilization, upon visual inspection, around 40% of vials had cosmetic defect with residual product around stopper of the vial and were categorized as "product on stopper" vials, whereas remaining 60% vials with no cosmetic defect were called "acceptable vials." Both groups of vials from 1 single batch were tested for critical quality attributes including protein concentration (ultraviolet absorbance at 280), residual moisture (Karl Fischer), sterility (membrane filtration), and container closure integrity (CCI) (blue dye ingress). Analysis of protein quality attributes such as aggregation, protein concentration, residual moisture showed no significant difference between vials with "product on stopper" and "acceptable vials." However, CCI of the "product on stopper" vials was compromised due to the presence of product around stopper of the vial. The results from this case study demonstrate the following 2 important findings: (1) that a seemingly cosmetic defect may impact product quality, compromising the integrity of the product and (2) that CCI test method can be used as an orthogonal method to sterility testing to evaluate sterility assurance of the product. The corrective action proposed to mitigate this defect is use of a larger sized vial that can potentially minimize this defect that arises because of product handling errors.

    2013-01-01

    Users' perceptions of new forms of products depend on various product qualities. As technology becomes increasingly mobile, carrying technology products on body is becoming more commonplace. As a result, these types of products hold different meanings and intentions for users than off-body products, which may lead to new interpretations. This paper investigates the relationship between the visual qualities of on-body interactive products and users' perceptions of those products. A brief literature review explores how technological developments have led to new modes of transporting products. This paper also examines the relative importance of changes in perceived qualities, technology acceptance and response to product appearance. Through user interviews, the authors explored the perceived qualities of conceptual designs for wearable phones, the meanings attached to these qualities and their relative importance. They present the results and follow with a discussion of the dimensions of product qualities and related characteristics that emerged. This study, investigating the perceived qualities of on-body interactive products and applying the repertory grid technique, determines what will lead users to avoid or approach these new technologies. It also presents a preliminary framework to help designers understand the perceived qualities of these products.

  7. A framework for analyzing the impact of data integrity/quality on electricity market operations

    Science.gov (United States)

    Choi, Dae Hyun

    This dissertation examines the impact of data integrity/quality in the supervisory control and data acquisition (SCADA) system on real-time locational marginal price (LMP) in electricity market operations. Measurement noise and/or manipulated sensor errors in a SCADA system may mislead system operators about real-time conditions in a power system, which, in turn, may impact the price signals in real-time power markets. This dissertation serves as a first attempt to analytically investigate the impact of bad/malicious data on electric power market operations. In future power system operations, which will probably involve many more sensors, the impact of sensor data integrity/quality on grid operations will become increasingly important. The first part of this dissertation studies from a market participant's perspective a new class of malicious data attacks on state estimation, which subsequently influences the result of the newly emerging look-ahead dispatch models in the real-time power market. In comparison with prior work of cyber-attack on static dispatch where no inter-temporal ramping constraint is considered, we propose a novel attack strategy, named ramp-induced data (RID) attack, with which the attacker can manipulate the limits of ramp constraints of generators in look-ahead dispatch. It is demonstrated that the proposed attack can lead to financial profits via malicious capacity withholding of selected generators, while being undetected by the existing bad data detection algorithm embedded in today's state estimation software. In the second part, we investigate from a system operator's perspective the sensitivity of locational marginal price (LMP) with respect to data corruption-induced state estimation error in real-time power market. Two data corruption scenarios are considered, in which corrupted continuous data (e.g., the power injection/flow and voltage magnitude) falsify power flow estimate whereas corrupted discrete data (e.g., the on/off status of

To teach it on a completely distance learning environment (e-learning imposes possibly other strategies, besides those that the e-learning model of Open University of Portugal dictates. This article analyses the behavior of the students of the 1st cycle in Computer Science while interacting with the object-oriented programming (OOP discipline available to them on the Moodle platform. Through the evaluation of the level of interaction achieved in a group of relevant selected actions by the students, it is possible to identify their relevancy to the success of the programming learning process. Data was extracted from Moodle, numerically analyzed, and, with the use of some charts, behavior patterns of students were identified. This paper points out potential new approaches to be considered in e-learning in order to enhance programming learning results, besides confirming a high level of drop-out and a low level of interaction, thus finding no clear correlation between students’ success and the number of online actions (especially in forums, which reveals a possible failure of the main pillar on which the e-learning model relies.

    2007-01-01

    The Configuration Management (CM) is an imperative discipline which helps in producing quality metal products for the customers. CM implements a graded approach to Configuration Items whose failure poses human as well as product losses. Effective CM provides information to Project Management, Quality Control, and Quality Assurance in identifying schedules and processes related to metal component production. The CM is a supportive function, mostly working side by side with Quality Assurance and Quality Control in the development / production of metal parts. The CM provides tools and guidelines for managing a product while Quality Assurance verifies and validates the same outside the scope of Configuration Audits. Configuration Management raises productivity of metal product, makes-available design reuse, reduces service and support costs, enhances visibility and eliminates rework on metal products. The elements of CM i.e. Identification, Control, Status Accounting and Audits playa vital role to enhance the quality of metal products. Only established CM System can make it possible to swing initial development criteria to final user friendly metal products. The challenges of today in our metal industry are to design and develop state-of-the-art products, for which, CM ideas given in this paper, will help to achieve all the set goals. (author)

    Full Text Available Creating and maintaining customer loyalty are strategic requirements for modern business. In the current competitive context, product quality and brand experience are crucial in building and maintaining customer loyalty. Consumer loyalty, which may be classified into cognitive loyalty and affective loyalty, is related to customers’ quality perception. Cue utilization theory distinguishes two dimensions for perceived quality, extrinsic quality –linked to the brand– and intrinsic quality –related with internal product characteristics. We propose that (i cognitive loyalty is more influenced by intrinsic product quality whereas extrinsic product quality (brand name is more salient for affective loyalty and, (ii different commercial stimuli have a differential effectiveness on intrinsic and extrinsic perceived quality. In fact, in this study, we analyze how perceived quality dimensions may influence the effectiveness of two different commercial stimuli: displays and advertising flyers. While displays work within the point of sale under time-constrained conditions where consumers are more likely to use heuristics to simplify their decisions, advertising flyers work outside of the point of sale under low time-constrained conditions, and therefore favor a more reasoned purchase decision where systematic processing will be more likely. We analyze the role of quality perception in determining the effectiveness of both these commercial stimuli for selling products that induce high purchase involvement and perceived risk. The empirical analysis focuses on computer products sold by one of Europe’s largest computer retailers and it combines scanner, observational, and survey data. The results show that both dimensions of quality perceptions moderate the influence of displays and advertising flyers on sales, but their impact is different on each commercial stimuli.

    The present study was designed to assess growth rate in area, yield and production of selected major food commodities and to project these parameters on the basis of estimated growth co-efficient. Time-series data for area, yield and production were collected for wheat, sugarcane, rice, mung and gram since 1980-81. The semi-log trend function was employed to find out the growth rate of selected commodities. The findings of the study showed the positive growth rates of area, production and yield of all selected food grain and legume crops. The estimated co-efficient for all growth models (area, production and yield) of selected commodities were statistically highly significant at 1 percentage level except yield of gram which was significant at 10 percentage level. The estimated annual growth rate of area for wheat, rice and sugarcane was 0.9 percentage, 2.1 percentage and 0.8 percentage, respectively with the production growth of 3.0 percentage, 3.8 percentage and 2.2 percentage, respectively and yield growth of 2.1 percentage, 1.6 percentage and 1.5 percentage, respectively. The results highlighted that the major contribution for expansion in production for rice and sugarcane was area while it was yield for wheat. In this scenario the wheat production can be enhanced by increasing its area than that of rice and sugarcane. The annual growth rate for gram and mung area was estimated about 1.0 v and 4.9 percentage, respectively, with the production growth rate of 2.3 percentage and 6.4 percentage while yield growth rate of 2.9 percentage and 1.4 percentage, respectively. Keeping in view the higher growth of gram yield the increase in its area may enhance its production more than that of mung. The proportionate higher increase in the area of wheat and gram may enhance the welfare of producers in particular and provide food security to masses in general. (author)

    Full Text Available A software product line is a complex system the aim of which is to provide a platform dedicated to large reuse. It necessitates a great investment. Thus, its ability to cope with customers’ ever-changing requirements is among its key success factors. Great effort has been made to deal with the software product line evolution. In our previous works, we carried out a classification of these works to provide an overview of the used techniques. We also identified the following key challenges of software product lines evolution: the ability to predict future changes, the ability to define the impact of a change easily and the improvement in understanding the change. We have already tackled the second and the third challenges. The objective of this paper is to deal with the first challenge. We use the cladistics classification which was used in biology to understand the evolution of organisms sharing the same ancestor and their process of descent at the aim of predicting their future changes. By analogy, we consider a population of applications for media management on mobile devices derived from the same platform and we use cladistics to construct their evolutionary tree. We conducted an analysis to show how to identify the evolution trends of the case study products and to predict future changes.

    The Six Sigma Model is a global quality management system applicable to the determination of glycated hemoglobin (HbA1c). In addition, this model can ensure the three characteristics influencing the patient risk: the correct performance of the analytical method with low inaccuracy and bias, the quality control strategy used by the laboratory, and the necessary quality of the analyte. The aim of this study is to use the Six Sigma Model for evaluating quality criteria in the determination of glycated hemoglobin HbA1c and its application to assess four different HbA1c analyzers. Four HbA1c analyzers were evaluated: HA-8180V®, D-100®, G8®, and Variant II Turbo®. For 20 consecutive days, two levels of quality control (high and low) provided by the manufacturers were measured in each of the instruments. Imprecision (CV), bias, and Sigma values (σ) were calculated with the data obtained and a method decision chart was developed considering a range of quality requirements (allowable total error, TEa). For a TEa = 3%, HA-8180V = 1.54 σ, D-100 = 1.63 σ, G8 = 2.20 σ, and Variant II Turbo = -0.08 σ. For a TEa = 4%, HA-8180V = 2.34 σ, D-100 = 2.32 σ, G8 = 3.74 σ, and Variant II Turbo = 0.16 σ. For a TEa = 10%, HA8180V = 7.12 σ, D-100 = 6.46 σ, G8 = 13.0 σ, and Variant II Turbo = 1.56 σ. Applying the Stockholm consensus and its subsequent Milan review to the results: the maximum level in quality requirements for HbA1c is an allowable total error (TEa) = 3%, G8 is located in region 2 σ (2.20), which is a poor result, and HA-8180V and D-100 are both in region 1 σ (1.54 and 1.63, respectively), which is an unacceptable analytical performance.

In this paper, the Panax notoginseng saponins (PNS immediate release tablet was taken as the research subject. By defining the dissolution of five active pharmaceutical ingredients and the tablet tensile strength as critical quality attributes (CQAs, influences of both the manipulated process parameters introduced by an orthogonal experiment design and the intermediate granules’ properties on the CQAs were fully investigated by different chemometric methods, such as the partial least squares, the orthogonal projection to latent structures, and the multiblock partial least squares (MBPLS. By analyzing the loadings plots and variable importance in the projection indexes, the granule particle sizes and the minimal punch tip separation distance in tableting were identified as critical process parameters. Additionally, the MBPLS model suggested that the lubrication time in the final blending was also important in predicting tablet quality attributes. From the calculated block importance in the projection indexes, the tableting unit was confirmed to be the critical process unit of the manufacturing line. The results demonstrated that the combinatorial use of different multivariate modeling methods could help in understanding the complex process relationships as a whole. The output of this study can then be used to define a control strategy to improve the quality of the PNS immediate release tablet. Keywords: Panax

    Development of the production and inspection technology for High Temperature Engineering Test Reactor (HTTR) fuel has been carried out by cooperative work between Japan Atomic Energy Research Institute (JAERI) and Nuclear Fuel Industries, Ltd (NFI). The performance and the quality level of the developed fuel are well established to meet the design requirements of the HTTR. For the commercial scale production of the fuel, statistical quality control and quality assurance must be carefully considered in order to assure the safety of the HTTR. It is also important to produce the fuel under well controlled process condition. To meet these requirements in the production of the HTTR fuel, a new production process and quality control system is to be introduced in the new facilities. The main feature of the system is a computer integrated control system. Process control data at each production stage of products and semi-products are all gathered by terminal computers and processed by a host computer. The processed information is effectively used for the production, quality and accountancy control. With the aid of this system, all the products will be easily traceable from starting materials to final stages and the statistical evaluation of the quality of products becomes more reliable.

    To characterize the usage patterns of new types of tobacco products (NTTPs) to develop effective strategies for the regulation of NTTPs in Korea. We conducted focus group interviews to identify the NTTP usage patterns of research subjects. The NTTPs were limited to electronic cigarettes (e-cigarettes), waterpipe tobacco, and rolling tobacco. We categorized 30 research subjects into 4 groups. The e-cigarette group was divided into adult and adolescent groups. Each group contained 7-8 subjects. An interview lasting approximately 2 hours was conducted with each group. Ninety percent of NTTP users used an NTTP in combination with conventional cigarettes. Subjects mostly bought NTTPs online, unlike how they bought cigarettes. Additionally, a great deal of information, such as how to use NTTPs and descriptions of NTTP products, was exchanged through online or offline societies. The primary reason why the subjects used NTTPs was that NTTPs offer a greater range of flavors and aromas than cigarettes. Moreover, NTTPs were felt to be less repulsive than cigarettes. NTTPs were not used as a cigarette substitute; rather, they were mostly used in places and situations where traditional cigarette smoking was not allowed. Based on the results of this study, the government should conduct studies on the effects of the combined use of NTTPs and cigarettes on the human body, obtain and provide accurate data regarding NTTP use, and develop and implement polices to ban NTTP advertising, which may arouse adolescents' curiosity, and the addition of flavoring substances to tobacco products.

Ten volunteers were included in the study, applying two different basic formulations on their forearms. After four weeks of product application, and also after one week of treatment remission, tape strips were collected from the different treatment sites, as well as from untreated skin. The biomarkers investigated were selected to cover different aspects of epidermal differentiation and in connection with moisturization and barrier function. Levels of Involucrin were increased in both treatments, compared to untreated skin, whereas the levels of Keratin-6 were decreased for both treatments. In addition, a pattern for increased levels of Hornerin and Claudin-1 was also detected. There were no significant differences between the two treatments, only for treatment compared to untreated, but there were tendencies for different effect on some of the biomarkers investigated, differences that may reach significance with increased sample size. The major differences between the two treatments in this study were seen after one week of product remission, although due to too small sample size these differences were not significant.

    Full Text Available How to sell fresh products quickly to decrease the storage cost and to meet customer quality requirement is of vital importance in the food supply chain. Bundling fresh products is an efficient strategy to promote sales and reduce storage pressure of retailers. In this paper, we consider the bundle pricing decisions for homogeneous fresh products with quality deterioration. The value of fresh products with quality deterioration is approximated as an exponential function based on which customer’s reservation prices are calculated. A nonlinear mixed integer programming model is used to formulate the bundle pricing problem for fresh products. By adding auxiliary decision variables, this model is converted into a mixed integer linear program. Numerical experiments and sensitive analysis are conducted to provide managerial insights for bundling fresh products with quality deterioration.

    Polyhydroxybutyrate (PHB) is a biodegradable thermoplastic that is produced by various microorganisms. Because of its potential to replace conventional plastics, it has been closely researched in the past few years. Methanotrophic bacteria, bacteria that consume methane, produce this bioplastic when it lacks certain nutrients. The utilization of methane to produce PHB shows much promise as methane is a cheap, plentiful gas. In this study, we observed the methanotroph, Methylosinus trichosporium OB3b , and its yield of PHB in the absence of nitrogen. The optical density of Methylosinus trichosporium OB3b was measured in order to observe cell growth and PHB production patterns over a 48 hour period.

    2016-01-01

    Creating and maintaining customer loyalty are strategic requirements for modern business. In the current competitive context, product quality, and brand experience are crucial in building and maintaining customer loyalty. Consumer loyalty, which may be classified into cognitive loyalty and affective loyalty, is related to customers' quality perception. Cue utilization theory distinguishes two dimensions for perceived quality, extrinsic quality—linked to the brand—and intrinsic quality—related with internal product characteristics. We propose that (i) cognitive loyalty is more influenced by intrinsic product quality whereas extrinsic product quality (brand name) is more salient for affective loyalty and, (ii) different commercial stimuli have a differential effectiveness on intrinsic and extrinsic perceived quality. In fact, in this study, we analyze how perceived quality dimensions may influence the effectiveness of two different commercial stimuli: displays and advertising flyers. While displays work within the point of sale under time-constrained conditions where consumers are more likely to use heuristics to simplify their decisions, advertising flyers work outside of the point of sale under low time-constrained conditions, and therefore favor a more reasoned purchase decision where systematic processing will be more likely. We analyze the role of quality perception in determining the effectiveness of both these commercial stimuli for selling products that induce high purchase involvement and perceived risk. The empirical analysis focuses on computer products sold by one of Europe's largest computer retailers and it combines scanner, observational, and survey data. The results show that both dimensions of quality perceptions moderate the influence of displays and advertising flyers on sales, but their impact is different on each commercial stimuli. Extrinsic quality perception increases to a greater extent the effect of displays due to the use of a brand

    The structure of organizations that provide services should reflect the possibilities of and constraints on production that arise from the market segments they serve. Organizational segmentation in health care is based on urgency and severity as well as disease type, bodily function, principal method, or population subgroup. The result is conflicting priorities, goals, and performance metrics. A managerial perspective is needed to identify activities with similar requirements for integration, coordination, and control. The arguments in this article apply new reasoning to the previous literature. The method used in this article to classify health care provision distinguishes different types of health problems that share generic constraints of production. The analysis leads to seven different demand-supply combinations, each with its own operational logic. These are labeled demand and supply-based operating modes (DSO modes), and constitute the managerial building blocks of health care organizations. The modes are Prevention, Emergency, One visit, Project, Elective, Cure, and Care. As analytical categories the DSO modes can be used to understand current problems. Several operating modes in one unit create managerial problems of conflicting priorities, goals, and performance metrics. The DSO modes are constructed as managerially homogeneous categories or care platforms responding to general types of demand, and supply constraints. The DSO modes bring methods of industrial management to bear on efforts to improve health care. © 2010 Milbank Memorial Fund. Published by Wiley Periodicals Inc.

    2006-01-01

    This paper provides an analysis of the effect of the skill/experience of the software development team on the quality of the final software product. A method for the assessment of software development team skill and experience is proposed, and was derived from a workforce management tool currently in use by the National Aeronautics and Space Administration. Using data from 26 smallscale software development projects, the team skill measures are correlated to 5 software product quality metrics from the ISO/IEC 9126 Software Engineering Product Quality standard. in the analysis of the results, development team skill is found to be a significant factor in the adequacy of the design and implementation. In addition, the results imply that inexperienced software developers are tasked with responsibilities ill-suited to their skill level, and thus have a significant adverse effect on the quality of the software product.

    Full Text Available The article analyses the modern state of products quality control management. It justifies a necessity of organisation of the quality control system under conditions of uninterrupted flow line production. It reveals problems connected with a low level of the products quality control management. It forms a set of factors of internal and external environments, which should be taken into account in the process of selection of a type of managerial actions by the products quality control. It considers specific features of identification of the most important factors at an enterprise on the basis of use of the matrix of strategic SWOT analysis. It offers a procedure of identification of a general assessment of factors of influence. It analyses a mechanism of use of main conceptual models, which reflect the system nature of quality management in an organisation – quality pyramids and quality loops. It proves a necessity of application of a principally new scheme of relations between the customer and enterprise, which envisages that requirements of the quality management system focus not on control and screening of semi-finished products, but on creation of conditions that exclude rejects. It considers the role of ISO 9000 in the system of quality management, which recommend the customers to make a preliminary assessment of activity of the producing enterprise.

    2013-01-01

    Full Text Available For some companies, visual inspection has become an essential step when seeking to improve the quality of their products. The aim of this control is to be sure of the perceived quality of the product, which often goes well beyond the quality expected by the customer. For this type of control, the controller should be able to detect any anomaly on a product, characterize this anomaly, and then evaluate it in order to decide if the product should be accepted or rejected. This paper describes how this characterization can be carried out and, more specifically, how to measure the impact of the local environment of an anomaly on the perceived quality of the product.

    2011-01-01

    Purpose We used Organization Risk Analyzer (ORA), a dynamic network analysis tool, to identify patient care unit communication patterns associated with patient safety and quality outcomes. Although ORA had previously had limited use in healthcare, we felt it could effectively model communication on patient care units. Methods Using a survey methodology, we collected communication network data from nursing staff on seven patient care units on two different days. Patient outcome data were collected via a separate survey. Results of the staff survey were used to represent the communication networks for each unit in ORA. We then used ORA's analysis capability to generate communication metrics for each unit. ORA's visualization capability was used to better understand the metrics. Results We identified communication patterns that correlated with two safety (falls and medication errors) and five quality (e.g., symptom management, complex self care, and patient satisfaction) outcome measures. Communication patterns differed substantially by shift. Conclusion The results demonstrate the utility of ORA for healthcare research and the relationship of nursing unit communication patterns to patient safety and quality outcomes. PMID:21536492

  9. Identifying and Analyzing Uncertainty Structures in the TRMM Microwave Imager Precipitation Product over Tropical Ocean Basins

    2016-01-01

    Despite continuous improvements in microwave sensors and retrieval algorithms, our understanding of precipitation uncertainty is quite limited, due primarily to inconsistent findings in studies that compare satellite estimates to in situ observations over different parts of the world. This study seeks to characterize the temporal and spatial properties of uncertainty in the Tropical Rainfall Measuring Mission Microwave Imager surface rainfall product over tropical ocean basins. Two uncertainty analysis frameworks are introduced to qualitatively evaluate the properties of uncertainty under a hierarchy of spatiotemporal data resolutions. The first framework (i.e. 'climate method') demonstrates that, apart from random errors and regionally dependent biases, a large component of the overall precipitation uncertainty is manifested in cyclical patterns that are closely related to large-scale atmospheric modes of variability. By estimating the magnitudes of major uncertainty sources independently, the climate method is able to explain 45-88% of the monthly uncertainty variability. The percentage is largely resolution dependent (with the lowest percentage explained associated with a 1 deg x 1 deg spatial/1 month temporal resolution, and highest associated with a 3 deg x 3 deg spatial/3 month temporal resolution). The second framework (i.e. 'weather method') explains regional mean precipitation uncertainty as a summation of uncertainties associated with individual precipitation systems. By further assuming that self-similar recurring precipitation systems yield qualitatively comparable precipitation uncertainties, the weather method can consistently resolve about 50 % of the daily uncertainty variability, with only limited dependence on the regions of interest.

  10. A model for analyzing influence of timber production on lichens for reindeer grazing

    1987-06-01

    Full Text Available A model for long-term analysis of the influence of timber production on lichens for reindeer grazing (Cladina, Alectoria, Bryoria spp and others in Sweden is presented. The annual production of and demand for lichens are estimated and compared. Production of these lichens is presumed to set the upper limit for the reindeer population. Reindeer graze on both ground and tree lichens, which both must be accessible in sufficient amounts and at the right times of the year if reindeer husbandry is to succeed without supplementary feeding. The model is based mainly on existing data, and uses are estimations from the National Forest Survey and the Hugin system for calculation of longterm potential cut (Bengtsson, 1981. Geographically the study is limited to Vasterbotten and Norrbotten, the northernmost counties in Sweden, where most reindeer husbandry in Sweden is located, and where reindeer grazing takes place over almost the whole area. The calculations cover a period of one hundred years from 1980, and are based on a timber production programme which relies more on «multiple use» than the current Swedish forest policy (Bengtsson, 1986. The annual production of ground lichens is calculated by multiplying the area covered with ground lichens by their increment as estimated from their rate of biomass increase, which in turn depends on site factors and age of the stand. The estimation of the area is based on data from the National Forest Survey. Sample plots with ground lichens are assumed to maintain lichens during the whole hundred year period. Areas with stands that have been thinned within ten years and stands younger than 20 years are excluded due to logging residues from thinnings and packed snow. Some of the remaining area cannot practically be utilized for reindeer grazing. Representatives of three communities of reindeer herders classified 212 plots from the National Forest Survey with ground lichens and assessed that 3/4 of the plots can be

  11. Pricing products: juxtaposing affordability with quality appeal.

    Science.gov (United States)

    1984-01-01

    Choosing appropriate product prices is 1 of the most crucial steps in creating an effective contraceptive social marketing (CSM) sales campaign. The Social Marketing Forum conducted an informal survey of social marketing project managers, international contractors, and marketing consultants to determine how CSM programs cope with pricing problems and ways to circumvent some obstacles. According to Diana Altman, a family planning consultant, low prices that make products available to needy individuals are more important than the program's self sufficiency, yet if prices are too low, consumers think the products were unusable in the US and thus were dumped on local markets. Other key factors include commercial competition, spiraling inflation rates, and problems with rising prices and retailer/distributor margins. A sampling of per capita gross national products indicates the poverty level of most CSM projects' target market. Consequently, CSM projects must set low pices, regardless of program operating costs. The goal often is to increase the demand and availability for contraceptives. The fact that social marketing products must pass through retail networks to reach consumers complicates the pricing equation. To deal with the problem, India's Nirodh program gives a 25% margin to distributors/wholesalers, compared to 6% offered on most other goods. Retailers also receive a 25% margin, more than double the commercial rate. Once prices are set, increases pose hazards. Local government approval often is a prerequisite and can require lengthy negotiations. Market studies remain a valuable approach to effective pricing, according to PNA's Mallamad and other research consultants. They cite such effective research strategies as test marketing products and asking consumers how prices affect buying habits. Further, CSM projects can jump over some pricing hurdles through creative marketing. An effective pricing strategy alone cannot produce a successful CSM program. Pricing

    Chicken is an ideal model for simplified recombinant antibody library generation. It has been rarely been reported to apply chicken single-chain variable fragments (scFvs) in immunoassays for the detection of antibiotic and chemical contaminants in animal food products. In this study, the scFvs (S-1 and S-5) were isolated from a phage display library derived from a hyperimmunized chicken. The checker board titration revealed that the optimum concentrations of S-1 and S-5 were 0.78 μg/mL and 0.44 μg/mL respectively, to obtain OD450 around 1.0 at 5 μg/mL of Gent-OVA coating concentration. Both S-1 and S-5 exhibited negligible cross reactivity with kanamycin and amikacin. The 50% inhibitory concentration (IC50) of S-1 and S-5 were 12.418 ng/mL and 14.674 ng/mL respectively. In the indirect competitive ELISA (ic-ELISA), the limits of detection for S-1 and S-5 were 0.147 ng/mL and 0.219 ng/mL respectively. The mean recovery for Gent ranged from 60.91% to 118.09% with no more than 10.35% relative standard deviation (RSD) between the intra-assay and the inter-assay. These results indicate the chicken scFv based ic-ELISA method is suitable for the detection of Gent residue in animal derived edible tissues and milk.

    Full Text Available Quality and productivity concepts were confusing and sometimes used interchangeably by experts both in industry and academics. Though researches, to some extent, tried to show the developments of quality and productivity, as yet, no research was devoted to study their evolution in a way to know how they reached into their existing form and their relationship, whether it existed. This study intends to disclose the reason behind the confusion and concept - intermix by studying the main advancements in the evolution of the two concepts. Their evolution is chronologically determined by grouping basic advancements in to distinct timeframes and their corresponding relationship is identified using natural selection and biased mutation approaches of evolution. The paper revealed that in the first period there was Seemingly Productivity; in the second Primarily Productivity; in the third Primarily Quality; in the fourth Primarily Quality-based Productivity (i.e. one after the other norm; and in the fifth period both quality and productivity will be equally primarily focus of firms (Primarily Quality and Productivity. Through logical justifications, observations made in the existing literature, and based on the nature of future competitiveness orientation, future relationship between the two concepts needs intelligence in that they will be equally, seemingly with trade-off, and concurrently important for organizational growth, agility, and excellence; one will never exist without the other, and after the other.

    Xinfeng Lai

    2015-01-01

    Full Text Available This paper develops two integrated optimization models of two-echelon inventory for imperfect production system under quality competition environment, in which the vendor’s production process is assumed to be imperfect, and JIT delivery policy is implemented to ship product from the vendor to the buyer. In the first model, product defect rate is fixed, and, in the second model, quality improvement investment is function of defect rate. The optimal policies of ordering quantity of buyer and shipment from vendor to buyer are obtained to minimize the expected annual total cost of vendor and buyer. Numerical examples are used to demonstrate the effectiveness and feasibility of the models. Sensitivity analysis is taken to analyze the impact of demand, production rate, and defect rate on the solution. Implications are highlighted in that both the vendor and the buyer can benefit from the vendor’s investing in quality improvement.

Design and methods: The total imprecision of Tosoh HLC-723GX was verified according to CLSI EP15-A2 protocol using commercial control materials (C-QC and pooled human whole blood samples (HWB. The Sigma metric was used for the evaluation of quality targets. HbA1c results were compared to automated CE (MiniCap Flex Piercing, Sebia, France and IA (Tina-quant HbA1c Gen 2, Cobas Integra 400+, Roche Diagnostics, USA procedures. Results: The total imprecision of Tosoh HLC-723GX-HbA1c for IFCC(mmol/mol and NGSP(% units was: 1.91/1.25% (HbA1c=31 mmol/mol/5.0% and 0.51/0.63% (HbA1c=84 mmol/mol/9.8% for C-QC, and 0.39/0.2% (HbA1c=47 mmol/mol/6.5% and 0.77/0.46% (HbA1c=94 mmol/mol/10.8% in HWB samples, respectively. Bland-Altman analysis did not reveal any deviation of the results between Tosoh HLC-723GX and CE: mean difference 0.0% (95%CI: −0.02927 to 0.02653%, while the mean HbA1c difference against IA was −0.07% (95%CI: −0.1039 to −0.02765. At the selected HbA1c clinical decision level (48 mmol/mol/6,5%, six sigma analysis gave σ value of 3.91, within a desirable classification of performance. Conclusion: The analytical performance of the Tosoh HLC-723GX complies with the rigorous quality criteria for clinical use of HbA1c, with the results comparable to the CE procedure. Tosoh HLC-723GX provides a plausible analytical choice for reliable HbA1c measurement in low-volume laboratories. Keywords: HbA1c, Quality targets, Six sigma, Tosoh HLC-723GX analyzer

    2012-01-01

    The manufacture of infant food is a highly complex process and needs an effective quality control beyond classical in-process parameters and a final microbiological analysis. To ensure a safe end -product, various tools, such as the Hazard Analysis Critical Control Points (HACCP), have been developed to facilitate the management of food safety. Every single infant formula ingredient must have an excellent quality and safety approach because even if an ingredient is used in very small quantities in a single product, serious consequences may arise if the quality and product safety are not taken seriously by the ingredient manufacturer. The purpose of this article was twofold: firstly, to briefly describe existing Quality Management Systems and, secondly, to highlight the consequences of non-quality. Copyright © 2012 S.

    The HEMOX Analyzer (TCS Scientific) has been used to measure the full oxygen-dissociation curve (ODC) and to calculate P(50) and the Hill coefficient. The effects of different anticoagulants on sample stability and P(50) values have not been evaluated extensively for this instrument. We characterized an artificial hemoglobin (Equil QC463) for quality control (QC) and compared P(50) values for blood samples drawn into 3 different anticoagulants (acid citrate dextrose [ACD], heparin, and EDTA). P(50) values were not stable in ACD but were stable in heparin and EDTA anticoagulants for up to 4 days. Tests with Equil QC463 showed that P(50) values were quite sensitive to small variations in buffer pH. Use of the correct anticoagulant and strict control of buffer pH are 2 parameters that need to be accounted for in best-practices use of this hemoximeter and before determining P(50).

    Full Text Available The specific weight of resource and power consuming technologies that is typical for Ukrainian economy, the absence of effective legal, administrative and economic mechanisms of management of nature and the low level of ecological society consciousness have led to the significant deterioration of environment state in Ukraine, excessive pollution of waters, air, and soil, accumulation of a large number of waste products. Besides, the produce as a result of such enterprises’ production affects consumers’ health badly. This causes the need to develop theory and methodology of production ecological quality accounting. The problem of quality is the most important factor of increasing of life level, economic, social and ecological security in market economy. This, the current research aims to formulate the essence of concept “ecological quality of production” The research determines that ecological quality is characterized by the following main 6 aspects: social, technical, legal, economic, aesthetic and ecological. If one of these six aspects does not work, we cannot speak about ecological quality of a certain commodity. Many various factors influence upon the level of ecological quality of products and services. According to their contents and directions, they can be united into the following main 6 groups: technical, organizational, economic and social, ecological and aesthetic and legal. The article determines the directions of production ecological quality increasing.

    2010-01-01

    This report describes the roles of Good Manufacturing Practices (GMP) in pharmaceutical product quality control. There are three keys to pharmaceutical product quality control. They are specifications, thorough product characterization during development, and adherence to GMP as the ICH Q6A guideline on specifications provides the most important principles in its background section. Impacts of the revised Pharmaceutical Affairs Law (rPAL) which became effective in 2005 on product quality control are discussed. Progress of ICH discussion for Pharmaceutical Development (Q8), Quality Risk Management (Q9) and Pharmaceutical Quality System (Q10) are reviewed. In order to reconstruct GMP guidelines and GMP inspection system in the regulatory agencies under the new paradigm by rPAL and the ICH, a series of Health Science studies were conducted. For GMP guidelines, product GMP guideline, technology transfer guideline, laboratory control guideline and change control system guideline were written. For the GMP inspection system, inspection check list, inspection memo and inspection scenario were proposed also by the Health Science study groups. Because pharmaceutical products and their raw materials are manufactured and distributed internationally, collaborations with other national authorities are highly desired. In order to enhance the international collaborations, consistent establishment of GMP inspection quality system throughout Japan will be essential.

    2010-01-01

    Basaka Lake, unlike most of the other terminal Lakes in Main Ethiopian Rift, is expanding at substantial rate. Its expansion is particular concern owing to its poor water quality. Different studies were conducted on Basaka Lake, but none of them addressed the complex Lake water balance components at different hydrologic periods and come up with decisive backgrounds for the cause and its potential damaging effect. The current study attempted to analyze the expansion of Basaka Lake since 1960s from Landsat images and other ancillary data and then assess the potential cause through conceptual water balance modeling. The work required combined use of remote sensing, GIS and hydrologic models. The decadal land use-land cover change (LUCC) was mapped and its effects on the hydrologic processes (runoff, soil loss and sedimentation) of the lake catchment were estimated. A conceptual Lake water balance model was systematically formulated, solved, calibrated and validated. Groundwater flux model was then developed as function of the other water balance components. Generally, a tremendous expansion of Basaka Lake, degradation of soil and water quality status at Matahara Sugar Estate (MSE), rapid LUCC and the resulting changes in the regimes of hydrologic processes in the Lake catchment are observed. These problems revealed the need for urgent mitigation measures. Therefore, sustainable Lake management measures that could minimize its potential environmental threats are suggested. Moreover, correcting measures that could reduce, if not prevented, the potential impacts of waterlogging and its allied problems at MSE are suggested. (author) [de

    Science.gov (United States)

    van Gerpen, Jon

    Biodiesel is produced by reacting vegetable oils or animal fats with alcohol in the presence of an alkaline catalyst. The resulting methyl esters, which are the biodiesel fuel, are separated from the by-product glycerin, and then washed with water and dehydrated to produce fuel that must meet standardized specifications. Degraded oils containing high levels of free fatty acids can also be converted to biodiesel, but pretreatment with acid-catalyzed esterification is required. The resulting fuel is suitable for use as a neat fuel in diesel engines or blended with conventional diesel fuel.

    In recent decades, we have observed an intensification of science, technology and innovation activities in Brazil. The increase in production of scientific papers indexed in international databases, however, has not been accompanied by an equivalent increase in the impact of publications. This paper presents a methodology for analyzing production and the impact of certain research areas in Brazil related to two aspects: the origin of the journals (national or foreign) and international collaboration. These two variables were selected for being of particular importance in understanding the context of scientific production and communication in countries with emerging economies. The sample consisted of papers written by Brazilian researchers in 19 subfields of knowledge published from 2002 to 2011, totaling 85,082 papers. To calculate the impact, we adopted a normalized indicator called the relative subfield citedness (Rw) using a window of 5 years to obtain measurements evaluated in 2 different years: 2007 and 2012. The data on papers and citations were collected from the Web of Science database. From the results, we note that most of the subfields have presented, from one quinquennium to another, improved performance in the world production rankings. Regarding publication in national and foreign journals, we observed a trend in the distribution maintenance of production of the subfields based on the origin of the journal. Specifically, for impact, we identified a lower Rw pattern for Brazilian papers when they were published in national journals in all subfields. When Brazilian products are published in foreign journals, we observed a higher impact for those papers, even surpassing the average global impact in some subfields. For international collaboration, we analyzed the percentage of participation of foreign researchers and the connection between collaboration and the impact of papers, especially emphasizing the distinction of hyperauthorship papers in terms of

    Full Text Available Rosaceae (strawberry, cherry, blackberry, red raspberry, and black raspberry dietary supplements and food products (total n = 74 were purchased and analyzed to determine their anthocyanin concentrations and profiles. Eight of the 33 dietary supplements had no detectable anthocyanins (five samples or were adulterated with anthocyanins from unlabeled sources (three samples. Five of 41 food products contained no detectable anthocyanins. In mg per serving, the dietary supplements tested contained 0.02–86.27 (average 10.00, and food products contained 0.48–39.66 (average 7.76. Anthocyanin levels between the dietary supplements and food products were not significantly different in mg per serving. Individual anthocyanin profiles can be used to evaluate quality of Rosaceae food products and dietary supplements. These findings show that increasing anthocyanin content and reducing adulteration could improve the quality of Rosaceae products available in the marketplace.

    Full Text Available Antimicrobial usage is common in Asian aquaculture. This study aimed to determine the quality of antimicrobial products used by Vietnamese striped catfish (Pangasianodon hypophthalmus farmers. Twenty one antimicrobial products (11 products contained a single antimicrobial and 10 products contained a mixture of two different antimicrobials commonly used by catfish farmers were obtained from so-called chemical shops located in the Mekong Delta, Vietnam. Ultra High Performance Liquid Chromatography Mass Spectrometry was used to analyze concentration of sulfonamides, trimethoprim, amoxicillin, cefalexin and ciprofloxacin whereas concentrations of florfenicol and doxycycline were analyzed by High Performance Liquid Chromatography with UV detection. Results revealed that only 4/11 products with a single antimicrobial and 2/10 products with a mixture of antimicrobials contained active substances within ±10% of the concentration declared on the product label. Two products with antimicrobial mixtures did not contain any of the declared antimicrobials. Comparing two batches, analysis of 11 products revealed that only one product contained a concentration of active compound that varied with less than 10% in both batches. Several product labels provided inadequate information on how to calculate therapeutic dosage and further stated withdrawal time despite lack of pharmacokinetic data on the antimicrobials in catfish. There is an urgent need to strengthen approval procedures and in particular regularly to monitor the quality of antimicrobials used in Vietnamese aquaculture.

    2013-10-01

    Cryopreservation of fish sperm has been studied for decades at a laboratory (research) scale. However, high-throughput cryopreservation of fish sperm has recently been developed to enable industrial-scale production. This study treated blue catfish (Ictalurus furcatus) sperm high-throughput cryopreservation as a manufacturing production line and initiated quality assurance plan development. The main objectives were to identify: (1) the main production quality characteristics; (2) the process features for quality assurance; (3) the internal quality characteristics and their specification designs; (4) the quality control and process capability evaluation methods, and (5) the directions for further improvements and applications. The essential product quality characteristics were identified as fertility-related characteristics. Specification design which established the tolerance levels according to demand and process constraints was performed based on these quality characteristics. Meanwhile, to ensure integrity throughout the process, internal quality characteristics (characteristics at each quality control point within process) that could affect fertility-related quality characteristics were defined with specifications. Due to the process feature of 100% inspection (quality inspection of every fish), a specific calculation method, use of cumulative sum (CUSUM) control charts, was applied to monitor each quality characteristic. An index of overall process evaluation, process capacity, was analyzed based on in-control process and the designed specifications, which further integrates the quality assurance plan. With the established quality assurance plan, the process could operate stably and quality of products would be reliable. Copyright © 2013 Elsevier Inc. All rights reserved.

    It is vitally important for a power plant to determine the coal property rapidly to optimize the combustion process. In this work, a fully software-controlled laser-induced breakdown spectroscopy (LIBS) based coal quality analyzer comprising a LIBS apparatus, a sampling equipment, and a control module, has been designed for possible application to power plants for offering rapid and precise coal quality analysis results. A closed-loop feedback pulsed laser energy stabilization technology is proposed to stabilize the Nd: YAG laser output energy to a preset interval by using the detected laser energy signal so as to enhance the measurement stability and applied in a month-long monitoring experiment. The results show that the laser energy stability has been greatly reduced from ± 5.2% to ± 1.3%. In order to indicate the complex relationship between the concentrations of the analyte of interest and the corresponding plasma spectra, the support vector regression (SVR) is employed as a non-linear regression method. It is shown that this SVR method combined with principal component analysis (PCA) enables a significant improvement in cross-validation accuracy by using the calibration set of coal samples. The root mean square error for prediction of ash content, volatile matter content, and calorific value decreases from 2.74% to 1.82%, 1.69% to 1.22%, and 1.23 MJ/kg to 0.85 MJ/kg, respectively. Meanwhile, the corresponding average relative error of the predicted samples is reduced from 8.3% to 5.48%, 5.83% to 4.42%, and 5.4% to 3.68%, respectively. The enhanced levels of accuracy obtained with the SVR combined with PCA based calibration models open up avenues for prospective prediction in coal properties.

  18. Intelligent Systems Approaches to Product Sound Quality Analysis

    Science.gov (United States)

    Pietila, Glenn M.

    As a product market becomes more competitive, consumers become more discriminating in the way in which they differentiate between engineered products. The consumer often makes a purchasing decision based on the sound emitted from the product during operation by using the sound to judge quality or annoyance. Therefore, in recent years, many sound quality analysis tools have been developed to evaluate the consumer preference as it relates to a product sound and to quantify this preference based on objective measurements. This understanding can be used to direct a product design process in order to help differentiate the product from competitive products or to establish an impression on consumers regarding a product's quality or robustness. The sound quality process is typically a statistical tool that is used to model subjective preference, or merit score, based on objective measurements, or metrics. In this way, new product developments can be evaluated in an objective manner without the laborious process of gathering a sample population of consumers for subjective studies each time. The most common model used today is the Multiple Linear Regression (MLR), although recently non-linear Artificial Neural Network (ANN) approaches are gaining popularity. This dissertation will review publicly available published literature and present additional intelligent systems approaches that can be used to improve on the current sound quality process. The focus of this work is to address shortcomings in the current paired comparison approach to sound quality analysis. This research will propose a framework for an adaptive jury analysis approach as an alternative to the current Bradley-Terry model. The adaptive jury framework uses statistical hypothesis testing to focus on sound pairings that are most interesting and is expected to address some of the restrictions required by the Bradley-Terry model. It will also provide a more amicable framework for an intelligent systems approach

    Capabilities of a portable X-ray tube-based analyzer were evaluated for screening foods, thin films, and ceramic glazes for toxic elements. A beverage spiked with Cr, Cu, and As and cocoa powder spiked with As and Pb could easily be distinguished from unadulterated products when analyzed through their original container walls. With calibration, results for thin films and ceramic glazes yielded accurate Pb results. Limits of detection (LODs) were 0.2-15 and 15 μg cm -2 , respectively, for Pb and Cd in thin films and about 2 μg cm -2 for Pb in glazes. With analysis times of 0.5-1 min, sensitivities and LODs were superior to those obtained with radioisotopic X-ray fluorescence analysis. (author)

    Analytical instrumentation continues its amazing evolution, especially in regard to generating ever more sensitive, faster, and reliable measurements. Perhaps the most difficult challenges are making these instruments small enough to use in the field, equipping them with well-designed software that facilitates and simplifies their use by nonexperts while preserving enough of their analytical capabilities to render them useful for a wide variety of applications. Perhaps the most impressive and underappreciated example of instruments that meet these criteria are field-portable X-ray fluorescence (XRF) analyzers. In the past, these analyzers have been routinely used for environmental applications (lead in paint and soil, metal particulates in air samples collected onto filters), geology studies (ore and soil analysis, precious metal identification), and recycling industries (alloy identification). However, their use in the analysis of toxic elements in food, food ingredients, dietary supplements, and medicinal and herbal products, especially within the FDA and regulatory environments, has been surprisingly limited to date. Although XRF will not replace atomic spectrometry techniques such as ICP-MS for sub-parts per million level analyses, it offers a number of significant advantages including minimal sample preparation, high sample throughputs, rapid and definitive identification of many toxic elements, and accurate quantitative results. As should be obvious from many recent news reports on elevated levels of toxic elements in children's lunchboxes, toys, and supplements, field-portable XRF analyzers can fill a very important niche and are becoming increasingly popular for a wide variety of elemental analysis applications. This perspective begins with a brief review of the theory of XRF to highlight the underlying principle, instrumentation, and spectra. It includes a discussion of various analytical figures of merit of XRF to illustrate its strengths and limitations

    2017-12-01

    Motivated by the Silk Road Economic Belt and the 21st-Century Maritime Silk Road project, i.e. the Belt and Road (B&R), more goods will flow around the world. With this trading platform, people can buy products at relatively cheap prices, and it is easier for people to buy various goods. The quality and quantity of products thus attract more and more attention in the supply chains. This paper discusses the quantity decision by considering the product quality in parallel supply chains where two manufacturers produce substitute products and then sell them to their downstream retailers separately. In terms of the changing quantity, as well as the different quality, this paper establishes a dynamic game model to explore the dynamic behavior when the optimal profits of two retailers have been calculated. The dynamic behaviors of the system, such as stable region, bifurcation and chaos, strange attractors and the largest Lyapunov exponents (LLE) are analyzed. The effect of the quantity adjustment parameter on the stability of the supply chain system is investigated through numerical simulations. Furthermore, a dynamic game model is established based on the quality delay decision, to investigate the influence of the quality delay parameter on the dynamic game model and the profits. Finally, the optimal decisions are obtained and analyzed.

    Standards of hygiene and health are of major importance in food production, and quality control has become obligatory in this field. Thanks to rapidly developing technologies, it is now possible for automatic and safe quality control of food production. For this purpose, image-processing-based quality control systems used in industrial applications are being employed to analyze the quality of food products. In this study, quality control of chicken (Gallus domesticus) eggs was achieved using a real time image-processing technique. In order to execute the quality control processes, a conveying mechanism was used. Eggs passing on a conveyor belt were continuously photographed in real time by cameras located above the belt. The images obtained were processed by various methods and techniques. Using digital instrumentation, the volume of the eggs was measured, broken/cracked eggs were separated and dirty eggs were determined. In accordance with international standards for classifying the quality of eggs, the class of separated eggs was determined through a fuzzy implication model. According to tests carried out on thousands of eggs, a quality control process with an accuracy of 98% was possible. © 2014 Society of Chemical Industry.

    This paper addresses a comprehensive modeling and functionality evaluation of a module-based quality system in production logistics at the highest domain abstract level of business processes. All domain quality business processes and quality data transactions are modeled using BPMN and UML tools and standards at the business process and data modeling. A modular web-based prototype is developed to evaluate the models addressing the quality information system functionality requirements and modularity in production logistics through data scenarios and data queries. Using the object-oriented technique in design at the highest domain level, the proposed models are subject further development in the lower levels for the implementing case. The models are specifically able to manipulate all quality operations including remedy and control in a lot-based make-to-order production logistics system as an individual module. Due to the specification of system as domain design structure, all proposed BPMs, data models, and the actual database prototype are seen referential if not a solution as a practical “to-be” quality business process re-engineering template. This paper sets out to provide an explanatory approach using different practical technique at modeling steps as well as the prototype implementation. (Author)

    Rhodiola rosea L. Crassulaceae, root (Golden Root, Arctic Root) is a high-value herbal medicinal product, registered in the UK for the treatment of stress-induced fatigue, exhaustion and anxiety based on traditional use and used throughout Europe as a herbal medicinal product for similar indications. Numerous unregistered supplements are also available. There are several Chinese species used in traditional Chinese medicine (TCM), including Rhodiola crenulata (Hook.f. & Thomoson) that is believed to be a common adulterant in the R. rosea value chain. The project is embedded in a larger study aiming to investigate the diverse value chains that lead to the production of R. rosea as an herbal medicinal product or supplement. Here we focus on a comparison of the quality of the finished products and assess any phytochemical variation between products registered under the Traditional Herbal Medicine Products Directive (THMPD) and products obtained from the market without any registration (i.e. generally unlicensed supplements). Our key aim is to establish the extent of the problem in terms of adulteration of consumer products claiming to contain R. rosea (or R. crenulata). Approximately 40 commercial products (granulated powders and extracts) were sourced from different suppliers. We analysed these samples using high performance thin layer chromatography (HPTLC), mass spectrometry (MS) and (1)H NMR spectroscopy coupled with multi-variate analysis software following a method previously developed by our group for the analysis of turmeric products. We investigate the phytochemistry of the different species and assess the potential of R. crenulata as an adulterant at the end of the R. rosea value chains. The consistency of the products varies significantly. Approximately one fifth of commercial products that claimed to be R. rosea did not contain rosavin (the key reference markers used to distinguish R. rosea from related species). Moreover some products appeared not to

    Full Text Available Application of waste liquor at a rate of 25% that contains the used quinone and is applied as an additive has shown that qualitative characteristics of the obtained desired product do not differ from a product while using fresh quinone for pulping of cellulose-containing vegetable raw material. For this reason process of obtaining the desired product (cellulose or semicellulose becomes economically cost-efficient on the basis of calculation and with due account of ecology. While analyzing investigation results pertaining to production of wood pulp from vegetable raw material (sprucewood it is possible to point out the fact that qualitative characteristics of the desired product have been improved due to addition of quinone in the process of alkaline wood pulping (sulphate and sodic. A number of research publications have described a positive influence of additives on alkaline delignification of vegetable raw material. It subsequently improves the quality of the desired product: reduction of lignin content in the product; an output increase in cellulose and hemicellulose, α-cellulose in cellulose; upgrading of physical and mechanical indices. All the above-mentioned elements and components contribute to better quality of the manufactured packing products. In this case formation of hazardous sulfur-containing compounds is fully excluded.

    Recombinant baculoviruses (rBac) are used for many different applications, ranging from bio-insecticides to the production of heterologous proteins, high-throughput screening of gene functions, drug delivery, in vitro assembly studies, design of antiviral drugs, bio-weapons, building blocks for electronics, biosensors and chemistry, and recently as a delivery system in gene therapy. Independent of the application, the quality, quantity and purity of rBac-based products are pre-requisites demanded by regulatory authorities for product licensing. To guarantee maximization utility, it is necessary to delineate optimized production schemes either using trial-and-error experimental setups ("brute force" approach) or rational design of experiments by aid of in silico mathematical models (Systems Biology approach). For that, one must define all of the main steps in the overall process, identify the main bioengineering issues affecting each individual step and implement, if required, accurate analytical methods for product characterization. In this review, current challenges for quality control (QC) technologies for up- and down-stream processing of rBac-based products are addressed. In addition, a collection of QC methods for monitoring/control of the production of rBac derived products are presented as well as innovative technologies for faster process optimization and more detailed product characterization.

    The muscles derived from livestock are highly perishable. Rapid and nondestructive methods are essential for quality assurance of such products. Potential nondestructive methods, which can supplement or replace many of traditional time consuming destructive methods, include colour and computer image analysis, NIR spectroscopy, NMRI, electronic nose, ultrasound, X-ray imaging and biosensors. These methods are briefly described and the research work involving them for products derived from livestock is reviewed. These methods will be helpful in rapid screening of large number of samples, monitoring distribution networks, quick product recall and enhance traceability in the value chain of livestock products. With new developments in the areas of basic science related to these methods, colour, image processing, NIR spectroscopy, biosensors and ultrasonic analysis are expected to be widespread and cost effective for large scale meat quality evaluation in near future.

    Human resources is the main factor in improving company performance not only in industrial products but also services. Therefore, all of the organization performers involved must work together to achieve product quality services expected by consumers. Educational institutions are the service industries which are educators and instructor involved in it. Quality of product and services produced depends on the education organization performers. This study did a survey of instructors in public and private universities in North Sumatra to obtain the factors that affect quality of human resources and productivity of human resources. Human resources quality is viewed by the elements of TQM. TQM elements that are discussed in this study are leadership, communication, training and education, support structure, measurement and reward and recognition. The results of this study showed a correlation numbers across the exogenous variables on endogenous variables relationships tend to be strong and be positive. In addition, elements of TQM are discussed except the support structure which has a direct influence on the quality of human resources. Variable leadership, reward and recognition and quality of human resources have a significant effect on productivity.

    The Solar-Institute Jülich (SIJ) developed the micro heliostat system - a small sized heliostat - during the last years. One special performance of the micro heliostat is the option to integrate inexpensive plastic elements. The use of plastic as a cost reducer in the heliostat technique is also offering the chance to integrate complex designed components with a higher quality and special system function. The plastic for this application requires a high standing against UV radiation and thermal cycles with a daily extreme temperature variation. The temperature range inside the closed micro heliostat box can annually fluctuate between -20 °C and 80 °C in the worst case. Special aging tests were designed and performed for the first time in cooperation with the Institute for Applied Polymer Science (IAP) in order to identify and qualify a resistance plastic for the micro heliostat. This systematic plastic aging testing for the micro heliostat is introduced here. The tests were carried out under extreme ambient situations, which simulate the temperature and irradiation conditions that the heliostat has to stand for years. A particular climate of arid areas with continuous high solar radiation was defined for these tests. Two accelerating aging methods were adapted to reach adequate aging results in a reduced time. The aging of the investigated kinds of plastics were followed by tensile test, impact test, measuring Shore hardness, dynamic-mechanical analysis, differential scanning calorimetry and Fourier transform infrared spectroscopy to compare the different types of polymers. Parallel to these tests running real outdoor tests were performed, to control this accelerated aging. To have adequate conditions that the plastic in a micro heliostat has to stand, an identical closed test box with a glass cover was designed. The test samples inside the box were irradiated by the sun. The wanted forecast for the analyzed plastic was defined by the comparison of the real and

    THERM is a state-of-the-art, Microsoft Windows{trademark}-based computer program developed at Lawrence Berkeley National Laboratory (LBNL) for use by building component manufacturers, engineers, educators, students, architects, and others interested in heat transfer. Using THERM, you can model two-dimensional heat-transfer effects in building components such as windows, walls, foundations, roofs, and doors; appliances; and other products where thermal bridges are of concern. THERM's heat-transfer analysis allows you to evaluate a product's energy efficiency and local temperature patterns, which may relate directly to problems with condensation, moisture damage, and structural integrity. THERM's two-dimensional conduction heat-transfer analysis is based on the finite-element method, which can model the complicated geometries of building products. The program's graphic interface allows you to draw cross sections of products or components to be analyzed. To create the cross sections, you can trace imported files in DXF or bitmap format, or input the geometry from known dimensions. Each cross section is represented by a combination of polygons. You define the material properties for each polygon and introduce the environmental conditions to which the component is exposed by defining the boundary conditions surrounding the cross section. Once the model is created, the remaining analysis (mesher and heat transfer) is automatic. You can view results from THERM in several forms, including U-factors, isotherms, heat-flux vectors, and local temperatures. This version of THERM includes several new technical and user interface features; the most significant is a radiation view-factor algorithm. This feature increases the accuracy of calculations in situations where you are analyzing non-planar surfaces that have different temperatures and exchange energy through radiation heat transfer. This heat-transfer mechanism is important in greenhouse windows, hollow

    Substantial differences exist between traditionally cooked and chemically designed ready-to-serve products and raise questions about the general principles and requirements of current food law. Differences in amino acid patterns were analyzed in four examples of chicken preparations (boiled chicken meat, traditionally prepared broth from whole chicken, and two commercial chicken broths), and four examples of vegetable broth (traditionally prepared, two commercial products one of which was claimed a BIO-product, and the classic German bouillon cube). Chicken meat contained 284 mg of free amino acids in 100 ml of the boiled meat homogenate, with physiological peaks of glutamate (14.5 mg/100 ml), glutamine (8.5 mg/100 ml), anserine (88 mg/100 ml) and carnosine (55 mg/100 ml). The patterns significantly differ in industrially designed chicken soups with elevated peaks of glutamate, and missing anserine or carnosine. Similar results were obtained in vegetable broths. In the classic German bouillon cube, glutamate accounts for 96% of all free amino acids. The amino acid composition of modern ready-to-serve chicken soups and vegetable broths are far from being similar to any natural composition. We need to question current legal definitions of food, and consider its impact on eating habits, appetite regulation and obesity.

    Since the launch of the NASA Terra and Aqua satellites in December 1999 and May 2002, respectively, atmosphere and land data acquired by the MODIS (Moderate Resolution Imaging Spectroradiometer) sensor on-board these satellites have been reprocessed five times at the MODAPS (MODIS Adaptive Processing System) located at NASA GSFC. The global land and atmosphere products use science algorithms developed by the NASA MODIS science team investigators. MODAPS completed Collection 6 reprocessing of MODIS Atmosphere science data products in April 2015 and is currently generating the Collection 6 products using the latest version of the science algorithms. This reprocessing has generated one of the longest time series of consistent data records for understanding cloud, aerosol, and other constituents in the earth's atmosphere. It is important to carefully evaluate and assess the quality of this data and remove any artifacts to maintain a useful climate data record. Quality Assessment (QA) is an integral part of the processing chain at MODAPS. This presentation will describe the QA approaches and tools adopted by the MODIS Land/Atmosphere Operational Product Evaluation (LDOPE) team to assess the quality of MODIS operational Atmospheric products produced at MODAPS. Some of the tools include global high resolution images, time series analysis and statistical QA metrics. The new high resolution global browse images with pan and zoom have provided the ability to perform QA of products in real time through synoptic QA on the web. This global browse generation has been useful in identifying production error, data loss, and data quality issues from calibration error, geolocation error and algorithm performance. A time series analysis for various science datasets in the Level-3 monthly product was recently developed for assessing any long term drifts in the data arising from instrument errors or other artifacts. This presentation will describe and discuss some test cases from the

    Biodiesel is an alternative fuel made from vegetable oils or animal fats. The fatty acid composition of the feedstock, which varies among and within species, is the main determinant of biodiesel quality. In this work we analyze the variability in biodiesel quality (density, kinematic viscosity, heating value, cetane number and iodine value) obtained from sunflower oil, by means of a validated crop model that predicts the fatty acid composition of one high-oleic, and three traditional (high-linoleic) sunflower hybrids. The model was run with a 10-year average weather data from 56 weather stations in Argentina, and simulation results were compared to the biodiesel standards of Argentina, USA and Europe. We show that biodiesel produced from sunflower oil does not have one fixed quality, but different qualities depending on weather conditions and agricultural practices, and that intraspecific variation in biodiesel quality can be larger than interspecific differences. Our results suggest that (a) sunflower oil from high-oleic hybrids is suitable for biodiesel production (within limits of all analyzed standards), regardless of growing conditions and (b) sunflower oil from traditional hybrids is suitable for biodiesel production under the standards of Argentina and USA, while only certain hybrids grown in warm regions (e.g., Northern Argentina, Southern USA, China, India, Pakistan) are suitable for biodiesel production according to the European standard

  19. Developing Product Quality Control for Standardization of Tsetse Mass Production. Working Material

    International Nuclear Information System (INIS)

    2002-01-01

    The recent Pan-African Tsetse and Trypanosomosis Eradication Campaign (PATTEC) provides a mechanism within which SIT will be one of the major components of an integrated areawide approach to the establishment of tsetse fly-free areas. Currently world-wide tsetse production is 1/40 of the projected requirement in 2006. To achieve this objective it is essential that quality control (QC) measures suitable for the expanded production be in place. Therefore, improved QC methodology has become a top priority. Improvements in QC methodology will help to ensure the attainment of these production goals and improve quality of rearing, minimize production costs and generate trained QC and production staff required to successfully produce flies and monitor their quality and suitability for release. The proposed CRP is designed to address these issues.

    Science.gov (United States)

    Dallas, David; Nielsen, Søren Drud

    2018-01-01

    Human milk and dairy products are important parts of human nutrition. In addition to supplying nutrients, milk proteins contain fragments-peptides-with important biological functions that are released during processing or digestion. Besides their potential functional relevance, peptides released during processing can be used as markers of ripening stage or product deterioration. Hence, identification and quantification of peptides in milk can be used to assay potential health benefits or product quality. This chapter describes how to extract, identify, and analyze peptides within breast milk, dairy products, and dairy digestive samples. We describe how to analyze extracted peptides with liquid chromatography-mass spectrometry, to use software to identify peptides based on database searching, and to extract peak areas for relative quantification of each peptide. We describe methods for data analysis, including predicting which enzymes are responsible for protein cleavage, identifying the site specificity of protein breakdown, mapping identified peptides to known bioactive peptides, and applying models to predict novel functional peptides.

    The aim of the present study was to examine the possibilities/advantages of using recently introduced in-line spectroscopic process analyzers (Raman, NIR and plasma emission spectroscopy), within well-designed experiments, for the optimization of a pharmaceutical formulation and its freeze-drying process. The formulation under investigation was a mannitol (crystalline bulking agent)-sucrose (lyo- and cryoprotector) excipient system. The effects of two formulation variables (mannitol/sucrose ratio and amount of NaCl) and three process variables (freezing rate, annealing temperature and secondary drying temperature) upon several critical process and product responses (onset and duration of ice crystallization, onset and duration of mannitol crystallization, duration of primary drying, residual moisture content and amount of mannitol hemi-hydrate in end product) were examined using a design of experiments (DOE) methodology. A 2-level fractional factorial design (2(5-1)=16 experiments+3 center points=19 experiments) was employed. All experiments were monitored in-line using Raman, NIR and plasma emission spectroscopy, which supply continuous process and product information during freeze-drying. Off-line X-ray powder diffraction analysis and Karl-Fisher titration were performed to determine the morphology and residual moisture content of the end product, respectively. In first instance, the results showed that - besides the previous described findings in De Beer et al., Anal. Chem. 81 (2009) 7639-7649 - Raman and NIR spectroscopy are able to monitor the product behavior throughout the complete annealing step during freeze-drying. The DOE approach allowed predicting the optimum combination of process and formulation parameters leading to the desired responses. Applying a mannitol/sucrose ratio of 4, without adding NaCl and processing the formulation without an annealing step, using a freezing rate of 0.9°C/min and a secondary drying temperature of 40°C resulted in

    There is a rapid progress of tissue banking especially Bone Banking in China, In order to strengthen the control on medical devices, Ministry of Public Health (MPH) issued the 'Regulation on Supervision of Critical Medical Devices, MPH Decree No. 54' in 1997. The SPTB was requested to submit new application for the approval of production and providing of tissue allografts. The needed documents are clinical reports, package insert, quality standards of product, Quality System Regulation (QSR) and audit report. Quality System Regulation document adopted the GMP standard for medical devices of FDA, US (21 CFR 620-1997). SPTB will amend the existed Quality Manual to suit the requirement of QSR. Referring to the AATB Standards, SPTB established 'Technical Standards' for Tissue Banking and was approved by the local government, which will be the supplement of the submitted QSR document. Considering the need of market control, MPH requested to submit a 'Quality Standard of Product' and the method of inspection. SPTB has completed such standards for final inspection of bone products, which includes the test for residual water, microbiology, bone species, colour and structure. In addition, the Tissue Bank has completed standards for in process inspection, which includes residual blood, radiation sterilization, initial bioburden, package leakage and biomechanics. In-process inspection is important for the control of non-conforming final products to assure the safety and efficacy of bone grafts. Methods of in process inspection and final inspection are described and discussed in this paper

    analyze the spatial distribution of PET on the surface of the studied lakes, based on the data derived from satellite images, using GIS analysis functions. The results indicate strong correlation (R2 up to 0.85) between E measured on the surface of the lakes and PET, and lower correlation between E and ET (R2 up to 0.31), based on eight-day cumulative data. Results are further improved when aggregated to the annually time scale (e.g. only for 2010), so for the relation between E and PET the R2 is up to 0.90, and for E and ET R2 is up to 0.92. Concerning the spatial distribution of PET on the lake surfaces, maximum values were identified, where the lake presents the greatest width. Based on the strong correlation identified between PET satellite product and E, we could use this relationship in the future for estimating the evaporation for unmonitored lakes. Considering the low spatial resolution of the MOD16 products, the possible errors related to land cover around the lake should be considered, especially if the lakes are small.

    Nurses are amongst the employees whose lives are fully affected by the quality of work life (QWL) as a consequence of dynamic changes in work environment. Excessive workload and poor work conditions are focal issues in nursing. The QWL assessment is an important and basic effort to deal with this issue. Moreover, staff productivity is a worthy goal of organizations tending to grow. If the relationship between the QWL and productivity becomes apparent, managers can provide conditions for promoting the QWL for personnel to be productive. To our knowledge, these variables and their relationships have not been studied yet among Iranian nurses. This descriptive study was carried out to investigate the relationship between the QWL and productivity among 360 clinical nurses working in the hospitals of Tehran University of Medical Sciences. Findings showed that the QWL is at a moderate level among 61.4% of the participants. Only 3.6% of the nurses reported that they were satisfied with their works. None of those who reported the productivity as low reported their work life quality to be desirable. Spearman-rho test showed a significant relationship between productivity and one's QWL (p productivity.

    Full Text Available The role of fishery product has been developed and acknowledged in terms of food security both as income sources and food supplies for developing countries. On the other hand, quality control has become a challenge in overcoming consumers’ decision to purchase the products. The objective of research is to understand and evaluate consumer behavior in purchasing the products in regards to quality dimension on fishery products by using non-probability sampling technique to 142 consumers in three different locations in Pontianak (shops, mini/supermarkets, and local markets. Data were gathered by in-depth interviews divided into four categories consisting of consumer profiles; product knowledge; perception and preference; and quality dimension variable with conjoint analysis. The result shows that price, flavor, moistness, texture, nutrition, packaging color, and packaging size do not affect consumers’ decision to purchase the products. On the contrary, package durability attribute is the primary factor in their decision to purchase, and it is then followed by packaging material, availability, flavor, guarantee, guarantee source, brand, packaging form, and product form. This is beneficial for producers to improve the quality factors and develop market opportunities in the future. Besides, consumers can obtain information on product characteristics to fulfill their expectation and satisfaction.Keywords: conjoint analysis, fishery products, non-probability sampling, purchase behavior, quality dimensionsABSTRAKPeran produk olahan perikanan telah berkembang dan diakui dalam keamanan pangan–baik sebagai sumber pendapatan maupun sumber makanan bagi negara-negara berkembang.

    Since global purchasing in the automotive industry has been taken up all around the world there is one main key factor that makes a TB-supplier today successful: Producing highest quality at lowest cost. The fact that Tailored Blanks, which today may reach up to 1/3 of a car body weight, are purchased on the free market but from different steel suppliers, especially in Europe and NAFTA, the philosophy on OEM side has been changing gradually towards tough evaluation criteria. "No risk at the stamping side" calls for top quality Tailored- or Tubular Blank products. Outsourcing Tailored Blanks has been starting in Japan but up to now without any quality request from the OEM side like ISO 13919-1B (welding quality standard in Europe and USA). Increased competition will automatically push the quality level and the ongoing approach to combine high strength steel with Tailored- and Tubular Blanks will ask for even more reliable system concepts which enables to weld narrow seams at highest speed. Beside producing quality, which is the key to reduce one of the most important cost driver "material scrap," in-line quality systems with true and reliable evaluation is going to be a "must" on all weld systems. Traceability of all process related data submitted to interfaces according to customer request in combination with ghost-shift-operation of TB systems are tomorrow's state-of-the-art solutions of Tailored Blank-facilities.

    Full Text Available This study took place in 17 rural properties that produce colonial cheese in three towns of the Cantuquiriguaçu region (Paraná state, Brazil. A questionnaire was applied, in order to collect data on the milk and colonial cheese production, so that data could be analyzed according to the Normative Instruction nº 30/2013 from MAPA (Brazilian Ministry of Agriculture, Livestock and Food Supply. The results indicated that the visited farms did not have a certificate attesting them as free from brucellosis and tuberculosis (100%, nor even a program for mastitis control, nor good practices on milking and handling of cheese, not to mention poor control of water quality, poor pest control and minimum cheese ripening. Thus, according to the criteria from the Normative Instruction nº 30 / 2013, those farms were considered unsuitable for the production. It is worth noting, however, that one of the towns has already taken measures that partially met requirements of the legislation, indicating that the adoption of public policies and more technical support might assist producers to become apt for the adequate production of cheese from raw milk.

    2011-02-01

    Full Text Available Sustainable development is a paradigm that has evolved over the time, since the ideas of socially acceptable and compatible development, on which it was originally based, are now supported by the more recent notions of ecological equilibria and production process economy, both of which need to be also preserved. Environmental and health safety, rational use of the natural resources and technological tools, upkeep of high social growth rates and respect of a social equity are the basis of the sustainability for any production process, including the agriculture. The new globalization framework has penalized small farms and, at the same time, has put serious constraints to the development of stronger economic systems (medium/large farms, as well. As consequence, the EU has outlined several strategic programs to support small agricultural systems in marginal areas by: 1 strengthening all the quality- related aspects of agricultural production, including nutritional and cultural traits associated to local, typical and in some cases to neglected crops; 2 improving traditional cultural practices by adapting the cropping cycles and fomenting new partnerships between the different parts of the production chain, as for example; promotion of small horticultural chains. Specific political actions for the horticultural production sector have also been developed. Some of these policies are specifically addressed to preserve the biodiversity and to create quality labels certifying typical and/or organic products. All of these are possible strategies that may counteract and cope with the globalization process and increase the competitiveness of many production systems especially those performed by local and small entrepreneurs. New sustainable development models are required by both the market and the implicit requirements of the production system, inside a context on which Europe must face with new emerging economies with lower production costs, by increasing

    1999-03-01

    For analyzing the decay and build-up characteristics of spallation products, the DCHAIN-SP code has been developed on the basis of the DCHAIN-2 code by revising the decay data and implementing the neutron cross section data. The decay data are newly processed from the data libraries of EAF 3.1, FENDL/D-1 and ENSDF. The neutron cross section data taken from FENDL/A-2 data library are also prepared to take account of the transmutation of nuclides by the neutron field at the produced position. The DCHAIN-SP code solves the time evolution of decay and build-up of nuclides in every decay chain by the Beteman method. The code can estimate the following physical quantities of produced nuclides: inventory, activity, decay heat by the emission of {alpha}, {beta} and {gamma}-rays, and {gamma}-ray energy spectrum, where the nuclide production rate estimated by the nucleon-meson transport code such as NMTC/JAERI97 is used as an input data. This paper describes about the function, the solution model and the database adopted in the code and explains how to use the code. (author)

  20. Analyzing the impact of climate and management factors on the productivity and soil carbon sequestration of poplar plantations.

    It is crucial to investigate how climate and management factors impact poplar plantation production and soil carbon sequestration interactively. We extracted above-ground net primary production (ANPP), climate and management factors from peer-reviewed journal articles and analyzed impact of management factor and climate on the mean annual increment (MAI) of poplar ANPP statistically. Previously validated mechanistic model (ED) is used to perform case simulations for managed poplar plantations under different harvesting rotations. The meta-analysis indicate that the dry matter MAI was 6.3 Mg ha(-1) yr(-1) (n=641, sd=4.9) globally, and 5.1 (n=292, sd=4.0), 8.1 (n=224, sd=4.7) and 4.4 Mg ha(-1) yr(-1) (n=125, sd=3.2) in Europe, the US and China, respectively. Poplar MAI showed a significant response to GDD, precipitation and planting density and formed a quadratic relationship with stand age. The low annual production for poplar globally was probably caused by suboptimal water availability, rotation length and planting density. SEM attributes the variance of poplar growth rate more to climate than to management effects. Case simulations indicated that longer rotation cycle significantly increased soil carbon storage. Findings of this work suggests that management factor of rotation cycle alone could have dramatic impact on the above ground growth, as well as on the soil carbon sequestration of poplar plantations and will be helpful to quantify the long-term carbon sequestration through short rotation plantation. The findings of this study are useful in guiding further research, policy and management decisions towards sustainable poplar plantations. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available Organisations constantly look for new, innovative solutions and methods which could be used to improve their efficiency and increase the quality of their products. Identifying the causes for returns is an important issue for modern compa-nies, as returns are the cause for the increase in production costs and, most importantly, the loss of credibility in the eyes of the client. Therefore, for the company to be able to sustain or strengthen its position on the market, it has to follow the rules of quality management. Especially important is the rule of constant improvement. This rule is primarily connected with preventing errors and defects from occurring at all the stages of the production process. To achieve that, one must, among other things, use quality management tools. The article presents an analysis of causes for returns of a vibrating screen produced by a company which manufactures machinery and equipment for the extractive industry, using quality management tools such as the Ishikawa diagram and Pareto analysis. The analysis allowed for the identifi-cation of the causes of client returns which could not be previously identified, and proposing solutions for them.

    Today, there is an increasing worldwide demand for botanicals. Developing countries heavily rely on plant-derived medicines for their primary healthcare. One reason amongst many is the relatively inexpensive process economics and the lack of stringent product governance associated with the exploitation of traditional plant medicines compared with modern medicine. Developed countries impose stringent good manufacturing practices and quality control measures on drug products derived from any manufacturing process, regardless of the primary raw material. However, several factors hamper the full-scale application of traditional plant medicines: lack of implementation of effective quality assurance in the manufacturing process; lack of traceability in the supply chain and associated value additions; and inefficient identification of molecular species that affect the therapeutic efficacy of the final product. There lacks an assessable, causative, and prognostic relationship between the raw materials, the manufacturing process and the final product quality. This article suggests some solutions that may be adopted by the phytodrug industry to widen its global reach and retain its credibility. Primarily among them is the implementation of hazards analysis and critical control point in the manufacturing process and employment of process analytical technology for ensuring minimal deviation from the manufacturing process of phytotherapeutics. © 2013 Wiley Periodicals, Inc. and the American Pharmacists Association.

    Natural resources are deteriorating very rapidly in the Gulf of Guayaquil and the area of influence in the Guayas Basin due to human activity. Specific problems are generated by the mismanagement of the aquaculture industry affecting the traditional agricultural sectors: rice, banana, sugarcane, cocoa, coffee, and soya also studied, and by human and industrial settlements. The development of industrial activities such as aquaculture (shrimp building for shrimp farming in ponds) and agriculture, have increasingly contributed to the generation of waste, degrading and potentially toxic elements in high concentrations, which can have adverse effects on organisms in the ecosystems, in the health of the population and damage the ecological and environmental balance. The productive Guayas ecosystem, consists of three interrelated ecosystems, the Gulf of Guayaquil, the Guayas River estuary and the Guayas Basin buffer. The objective of this study was to evaluate the environmental quality of the productive Guayas ecosystem (Ecuador), through operational and specific objectives: 1) Draw up the transition coastal zone in the Gulf of Guayaquil, 2) Set temporal spatial variability of soil salinity in wetlands rice, Lower Guayas Basin, 3) evaluate the heavy metals in wetland rice in the Lower Basin of Guayas. The physical and chemical parameters of the soils have been studied. These are indicators of environmental quality. The multivariate statistical method showed the relations of similarities and dissimilarities between variables and parameter studies as stable. Moreover, the boundaries of coastal transition areas, temporal spatial variability of soil salinity and heavy metals in rice cultivation in the Lower Basin of Guayas were researched. The sequential studies included and discussed represent a broad framework of fundamental issues that has been valued as a basic component of the productive Guayas ecosystem. They are determinants of the environmental quality of the Guayas

    The environmental impact assessment (EIA) has been a tool for decision makers since the enactment of the National Environmental Policy Act (NEPA). Since that time, few analyses have been performed to verify the quality of information and content within EIAs. High quality information within assessments is vital in order for decision makers, stake holders, and the public to understand the potential impact of proposed actions on the ecosystem and wildlife species. Low quality information has been a major cause for litigation and economic loss. Since 1999, wind energy development has seen an exponential growth with unknown levels of impact on wildlife species, in particular bird and bat species. The purpose of this article is to: (1) develop, validate, and apply a quantitative index to review avian/bat assessment quality for wind energy EIAs; and (2) assess the trends and status of avian/bat assessment quality in a sample of wind energy EIAs. This research presents the development and testing of the Avian and Bat Assessment Quality Index (ABAQI), a new approach to quantify information quality of ecological assessments within wind energy development EIAs in relation to avian and bat species based on review areas and factors derived from 23 state wind/wildlife siting guidance documents. The ABAQI was tested through a review of 49 publicly available EIA documents and validated by identifying high variation in avian and bat assessments quality for wind energy developments. Of all the reviewed EIAs, 66% failed to provide high levels of preconstruction avian and bat survey information, compared to recommended factors from state guidelines. This suggests the need for greater consistency from recommended guidelines by state, and mandatory compliance by EIA preparers to avoid possible habitat and species loss, wind energy development shut down, and future lawsuits. - Highlights: ► We developed, validated, and applied a quantitative index to review avian/bat assessment quality

    Health-related quality of life has become an increasingly important indicator of health status in clinical trials and epidemiological research. Moreover, the study of the relationship of health-related quality of life with patients and disease characteristics has become one of the primary aims of many health-related quality of life studies. Health-related quality of life scores are usually assumed to be distributed as binomial random variables and often highly skewed. The use of the beta-binomial distribution in the regression context has been proposed to model such data; however, the beta-binomial regression has been performed by means of two different approaches in the literature: (i) beta-binomial distribution with a logistic link; and (ii) hierarchical generalized linear models. None of the existing literature in the analysis of health-related quality of life survey data has performed a comparison of both approaches in terms of adequacy and regression parameter interpretation context. This paper is motivated by the analysis of a real data application of health-related quality of life outcomes in patients with Chronic Obstructive Pulmonary Disease, where the use of both approaches yields to contradictory results in terms of covariate effects significance and consequently the interpretation of the most relevant factors in health-related quality of life. We present an explanation of the results in both methodologies through a simulation study and address the need to apply the proper approach in the analysis of health-related quality of life survey data for practitioners, providing an R package.

    Koivumäki, Tuuli P; Gürbüz, Göker; Heinonen, I Marina

    2017-09-01

    α-Lactalbumin (α-La), a major milk whey protein, is comprised of several amino acids prone to metal-catalyzed oxidation (MCO) typical in processing and during storage of foods. New tools are needed for the detection of characteristic oxidation products especially from tryptophan and cysteine that often remain unrecognized when using the traditional methods of carbonyl formation monitoring. In this study, the oxidative changes in α-La were investigated through tryptic digestion and collection of 3 descriptive peptides fitted into a metal-catalyzed oxidation (Fenton reaction) model. The peptide samples were oxidized at +37 °C for 14 d and explored with liquid chromatography-quadrupole ion trap-mass spectrometer (LC-MS n ). The fractionated α-La peptides were valyl-glycyl-isoleucyl-asparaginyl-tyrosyl-tryptophyl-leucyl-alanyl-histidyl-lysine (VGINYWLAHK), leucyl-aspartyl-glutaminyl-tryptophyl-leucyl-cysteinyl-glutamyl-lysine (LDQWLCEK), and tryptophyl +16 -leucyl-alanyl-histidyl-lysyl-alanyl-leucyl-cysteine (W +16 LAHKALC). Oxidation of several amino acids, such as cysteine, histidine, lysine, and tryptophan was observed. In the peptide LDQWLCEK, cysteine was rapidly trioxidized to sulfonic acid, followed by other amino acid side chains as secondary oxidation sites. Tryptophan oxidation was more pronounced in the peptides W +16 LAHKALC and VGINYWLAHK, and also formation of the harmful N-formylkynurenine was observed. As a conclusion, several stable and promising oxidation markers are proposed for α-La, which could be implemented in the evaluation of quality and safety of dairy protein-containing products. © 2017 Institute of Food Technologists®.

    2008-07-13

    Although the emergence of markets for high efficiency off-grid lighting technologies holds promise, realizing the potential of this opportunity on a long-term, sustainable basis requires careful attention to issues of product quality, consumer protection, and the potential for significant 'market spoiling', in anticipation of increases of sales of low cost, low performance off-grid lighting products. The goal of the Lighting Africa quality assurance workshop was to articulate strategies to mitigate the dangers of market spoiling and to explore ways to protect consumers from misleading advertising for sales of inferior, off-grid lighting products in the context of Lighting Africa's overarching objective to support the industry in developing a robust off-grid lighting market in Africa. The workshop resulted in the identification of two strategic approaches for meeting Lighting Africa quality assurance programmatic needs. The first strategy is intended to meet a short-term programmatic need for quality associated with requests for lighting products by bulk procurement agents, such as in a World Bank-financed project. The development of procurement specifications and test procedures that could be used in a quality/usability screening method in order to provide guidance for forthcoming large volume purchases emerged as the best solution to meet this need. Such approaches are used in World Bank-financed solar home systems (SHSs) projects in Bangladesh, Sri Lanka, and China, among others. However, unlike the SHSs which have multiple balance-of-system (BOS) components warranting the need for an array of specifications for individual components, stand alone lighting systems require specifications that are amenable to individual light points. To test this approach, Lighting Africa elected to use the technical specifications issued by the Photovoltaic Global Approval Program for solar lanterns that use CFL bulbs (PVRS11A) as the basis of qualifying such

    One of the most frequently used methods to improve product quality is complex FMEA. (Failure Modes and Effects Analyses). In the literature various FMEA is known, depending on the mode and depending on the targets; we mention here some of these names: Failure Modes and Effects Analysis Process, or analysis Failure Mode and Effects Reported (FMECA). Whatever option is supported by the work team, the goal of the method is the same: optimize product design activities in research, design processes, implementation of manufacturing processes, optimization of mining product to beneficiaries. According to a market survey conducted on parts suppliers to vehicle manufacturers FMEA method is used in 75%. One purpose of the application is that after the research and product development is considered resolved, any errors which may be detected; another purpose of applying the method is initiating appropriate measures to avoid mistakes. Achieving these two goals leads to a high level distribution in applying, to avoid errors already in the design phase of the product, thereby avoiding the emergence and development of additional costs in later stages of product manufacturing. During application of FMEA method using standardized forms; with their help will establish the initial assemblies of product structure, in which all components will be viewed without error. The work is an application of the method FMEA quality components to optimize the structure of the electrical parking brake (Electric Parching Brake - E.P.B). This is a component attached to the roller system which ensures automotive replacement of conventional mechanical parking brake while ensuring its comfort, functionality, durability and saves space in the passenger compartment. The paper describes the levels at which they appealed in applying FMEA, working arrangements in the 4 distinct levels of analysis, and how to determine the number of risk (Risk Priority Number); the analysis of risk factors and established

    Full Text Available The objective of this work was to evaluate the impacts of spittlebug (Mahanarva fimbriolata attack on sugarcane quality and ethanol production. Technological and microbiological parameters of juice and fermentation process were evaluated in ten fermentation cycles and two harvest seasons. Treatments consisted of different spittlebug stalk damage levels: control, with 100% of apparently healthy stalks; medium, with 15% of damaged or dry stalks (DDS; high, with 30% of DDS; and very high, with 60% of DDS. Spittlebug attack caused significant losses in cane quality, reducing total soluble solids, sucrose content, total reducing sugars, and pH, and increasing total phenolic compounds, and total and volatile juice acidity. The fermentation process was also significantly affected, resulting in lower ethanol content in wine. There was an increase in acetaldehyde concentration in the distillate. The spittlebug attack caused negative impacts on sugarcane quality and fermentation process, and these impacts are stronger in late season harvests.

    Full Text Available Skorup is Montenegrin traditional dairy product. Its main characteristics are extremely high content of milk fat and centuries-old technology. Due to the specific technology, high nutritional value and its historical heritage, Skorup deserves to be labelled as product with protected designation of origin (PDO or protected geographical indication (PGI. The purpose of this study was to collect the most important data about Skorup technology and quality and to launch the process of protection. The chemical quality of raw milk was analysed using IR spectrophotometry, the number of somatic cells and total bacteria count by flow cytometry, and Skorup composition by FTIR spectrophotometry. The presence of Escherichia coli, coagulase positive staphylococci and aerobic mesophilic bacteria in Skorup was detected by standard broth base methods. All Skorup samples contained more than 80 % of fat in dry matter, more than 70 % dry matter, approximately 60 % milk fat and 6 % proteins. The sensory characteristics of all samples were excellent, and according to sensory classification, they belong to the highest classes (I and IA. However, five out of twenty samples did not meet requirements for hygienic quality, which implies the urgent need for improvement of hygiene conditions during its production.

    Volumetric productivity and product quality are two key performance indicators for any biopharmaceutical cell culture process. In this work, we showed proof-of-concept for improving both through the use of alternating tangential flow perfusion seed cultures coupled with high-seed fed-batch production cultures. First, we optimized the perfusion N-1 stage, the seed train bioreactor stage immediately prior to the production bioreactor stage, to minimize the consumption of perfusion media for one CHO cell line and then successfully applied the optimized perfusion process to a different CHO cell line. Exponential growth was observed throughout the N-1 duration, reaching >40 × 10(6) vc/mL at the end of the perfusion N-1 stage. The cultures were subsequently split into high-seed (10 × 10(6) vc/mL) fed-batch production cultures. This strategy significantly shortened the culture duration. The high-seed fed-batch production processes for cell lines A and B reached 5 g/L titer in 12 days, while their respective low-seed processes reached the same titer in 17 days. The shortened production culture duration potentially generates a 30% increase in manufacturing capacity while yielding comparable product quality. When perfusion N-1 and high-seed fed-batch production were applied to cell line C, higher levels of the active protein were obtained, compared to the low-seed process. This, combined with correspondingly lower levels of the inactive species, can enhance the overall process yield for the active species. Using three different CHO cell lines, we showed that perfusion seed cultures can optimize capacity utilization and improve process efficiency by increasing volumetric productivity while maintaining or improving product quality. © 2014 American Institute of Chemical Engineers.

    Quality by design (QbD) is a systematic approach that begins with predefined objectives and emphasizes product and process understanding and process control. It is an approach based on principles of sound science and quality risk management. As the food processing industry continues to embrace the idea of in-line, online, and/or at-line sensors and real-time characterization for process monitoring and control, the existing gaps with regard to our ability to monitor multiple parameters/variables associated with the manufacturing process will be alleviated over time. Investments made for development of tools and approaches that facilitate high-throughput analytical and process development, process analytical technology, design of experiments, risk analysis, knowledge management, and enhancement of process/product understanding would pave way for operational and economic benefits later in the commercialization process and across other product pipelines. This article aims to achieve two major objectives. First, to review the progress that has been made in the recent years on the topic of QbD implementation in processing of food products and second, present a case study that illustrates benefits of such QbD implementation.

    A demand on raw fermented meat products depends on their availability, price and the culture. In Poland, raw meat products have a several hundred years, although limited to the Podlasie region, tradition of manufacturing. Therefore, in spite of widening of Italian, Spanish, Portuguese, German and recently even the Czech Republic products assortment on the Polish market, the consumption of them increases slowly. The aim of the study was to compare the sensory quality of raw ripened smoked products and sausages, sold on the Polish foodstuffs market as "traditional". The study included the basic chemical content, water activity, pH, the amount of lactic acid bacteria and coagulase-negative cocci, as well as selected texture and sensory parameters. The analysis was conducted in compliance with Polish Standards, and the cutting strength was measured with the use of the TA-XT2 texture-meter. The sensory analysis was conducted by a 12-person panel using the 5-point method. The differences in the amount of water, protein, fat and salt resulted from the wide variability of ingredients among both groups of the analysed cold meats. The smoked products were characterised by a higher pH (5.6-5.9), smaller amount of bacilli (2-5.5 log cfu/g) and lactic cocci (3.3 to 6.6 log cfu/g) in comparison with the sausages. The amount of both populations of bacteria in the sausages of a pH of 4.5-5.5 ranged from 6.8-8.9 log cfu/g and 5.9-7.7 log cfu/g, respectively. Among the analysed smoked products and sausages the greatest TPA hardness (respectively 128.6-140.3 N and 91.3-139.7 N), TPA chewiness (28.9-54.2 N and 16.1-36.0 N) and cutting strength (11.0-12.9 kG and 8.2-8.5 kG) was observed in those with a 0.81-0.86 water activity. The overall quality of the analysed cold meats was at a good level (3.9-4.1 pt). Distinguishing features which determined the quality of products are hardness, juiciness as well as odour. The specific odour of the yeast cultures present on the surface of the

    2017-12-01

    In the beginning, cheese making in the United States was all art, but embracing science and technology was necessary to make progress in producing a higher quality cheese. Traditional cheese making could not keep up with the demand for cheese, and the development of the factory system was necessary. Cheese quality suffered because of poor-quality milk, but 3 major innovations changed that: refrigeration, commercial starters, and the use of pasteurized milk for cheese making. Although by all accounts cold storage improved cheese quality, it was the improvement of milk quality, pasteurization of milk, and the use of reliable cultures for fermentation that had the biggest effect. Together with use of purified commercial cultures, pasteurization enabled cheese production to be conducted on a fixed time schedule. Fundamental research on the genetics of starter bacteria greatly increased the reliability of fermentation, which in turn made automation feasible. Demand for functionality, machinability, application in baking, and more emphasis on nutritional aspects (low fat and low sodium) of cheese took us back to the fundamental principles of cheese making and resulted in renewed vigor for scientific investigations into the chemical, microbiological, and enzymatic changes that occur during cheese making and ripening. As milk production increased, cheese factories needed to become more efficient. Membrane concentration and separation of milk offered a solution and greatly enhanced plant capacity. Full implementation of membrane processing and use of its full potential have yet to be achieved. Implementation of new technologies, the science of cheese making, and the development of further advances will require highly trained personnel at both the academic and industrial levels. This will be a great challenge to address and overcome. Copyright © 2017 American Dairy Science Association. Published by Elsevier Inc. All rights reserved.

    The experimental materials comprised cooked coarsely-ground and finely-ground sausages. The sausages were packaged in vacuum (V) and in modified atmospheres with the following composition: 20 % CO2, 80 % N2 (A1); 50 % CO2, 50 % N2 (A2); 80 % CO2, 20 % N2 (A3). The samples were stored at around 4 °C for 15 days. The measurements were repeated 8 times: at the completion of the production process and at 3-day intervals (day 0, 3, 6, 9, 12, 15) during storage. Drip loss changes in the package were analyzed during storage. Meat products were subjected to a sensory evaluation. The obtained results show that changes in the quality of meat products packaged under modified atmosphere are significantly influenced by the composition of the applied atmosphere. A wider range of quality changes were noted in vacuum-packaged products. Changes in the quality of modified atmosphere packaged products were less significant.

  13. Influence of raw milk quality on processed dairy products: How do raw milk quality test results relate to product quality and yield?

    This article provides an overview of the influence of raw milk quality on the quality of processed dairy products and offers a perspective on the merits of investing in quality. Dairy farmers are frequently offered monetary premium incentives to provide high-quality milk to processors. These incentives are most often based on raw milk somatic cell and bacteria count levels well below the regulatory public health-based limits. Justification for these incentive payments can be based on improved processed product quality and manufacturing efficiencies that provide the processor with a return on their investment for high-quality raw milk. In some cases, this return on investment is difficult to measure. Raw milks with high levels of somatic cells and bacteria are associated with increased enzyme activity that can result in product defects. Use of raw milk with somatic cell counts >100,000cells/mL has been shown to reduce cheese yields, and higher levels, generally >400,000 cells/mL, have been associated with textural and flavor defects in cheese and other products. Although most research indicates that fairly high total bacteria counts (>1,000,000 cfu/mL) in raw milk are needed to cause defects in most processed dairy products, receiving high-quality milk from the farm allows some flexibility for handling raw milk, which can increase efficiencies and reduce the risk of raw milk reaching bacterial levels of concern. Monitoring total bacterial numbers in regard to raw milk quality is imperative, but determining levels of specific types of bacteria present has gained increasing importance. For example, spores of certain spore-forming bacteria present in raw milk at very low levels (e.g., products to levels that result in defects. With the exception of meeting product specifications often required for milk powders, testing for specific spore-forming groups is currently not used in quality incentive programs in the United States but is used in other countries (e.g., the

    Three objectives of the present study are formulated: (1) to investigate whether total sensory pollution load on the air in space can be estimated by adding sensory pollution loads from the individual pollution sources; (2) to develop alternative reference exposures which can be used to calibrate sensory evaluations of the air quality indoors made by trained subjects; and (3) to investigate whether decreasing the pollution loads on the air indoors is an effective measure for improving the perceived air quality, reducing the prevalence of health symptoms and increasing people`s productivity. Limited data exist on the addition of families of sensory pollution, sources, i.e., building materials, people and tobacco smoke (research was mainly performed on building materials), and that no field study on addition has been carried out previously. Consequently, laboratory and field experiments on the addition of families of sensory pollution sources were undertaken. Reducing the sensory pollution load on the air indoors proved to be an effective and energy-efficient measure to improve the perceived quality of air, to lower the prevalence of symptoms and to improve productivity. Suggestions for future experiments are made including, i.a., using other sub-populations of subjects stratified for age, sensitivity and type of work, other pollution sources, as well as the independent measures design and repeated exposures to the same environmental conditions.

    A manufacture in Bandung produce kind of rubber-based product i.e. trim, rice rollers, shoe soles, etc. After penetrating the shoe soles market, the manufacture has met customer with tight quality control. Based on the past data, defect level of this product was 18.08% that caused the manufacture’s loss of time and money. Quality improvement effort was done using six sigma method that included phases of define, measure, analyse, improve, and control (DMAIC). In the design phase, the object’s problem and definition were defined. Delphi method was also used in this phase to identify critical factors. In the measure phase, the existing process stability and sigma quality level were measured. Fishbone diagram and failure mode and effect analysis (FMEA) were used in the next phase to analyse the root cause and determine the priority issues. Improve phase was done by designing alternative improvement strategy using 5W1H method. Some improvement efforts were identified, i.e. (i) modifying design of the hanging rack, (ii) create pantone colour book and check sheet, (iii) provide pedestrian line at compound department, (iv) buying stop watch, and (v) modifying shoe soles dies. Some control strategies for continuous improvement were proposed such as SOP or reward and punishment system.

    Full Text Available As a result of lack of conformity of the outer diameter of the filling piston of plastic syringe to the specifications set out in the design map and the increased demand for its  products from the Medical syringes factory – Babylon. The research conducts the necessary investigations and  analysis of the production process as most of the units rejected by fact that the outer diameter of the filling piston is smaller than the minimum specification and units returned to work  due to the fact that  the outer diameter larger than the upper limit of the specification.13The research aims firstly to examine the outer diameter of the filling piston through the use of the control chart of the variables represented by the average , and its impact on the production process capability because the increase in diameter specification leads to an increase in the pressure imposed on the lining of the cylinder, causing difficulty in piston movement and a decrease in diameter specification which leads to loose the process capability to prevent leakage of fluid, causing air to enter as well as to speed the movement of the piston, which negatively affects human life in both cases. Secondly, study the possibility of improving the production process capability by using advanced levels of the sigma.The results showed that the production process in the case of a disciplined and follows a normal distribution, the pointer of  the production process capability is equal to (0.55 and the factory works within the level of Sigma equal to (1.65. The proportion of a damaged product is (15.8 % and rework (0.99 %.In order to  reduce the proportion of damaged product, this paper introduces a quality plan depending on ( ±0.025 as tolerance limits instead of ( ±0.05 to increase sigma level by 202%.

    Remote sensing in the optical domain is widely used in agricultural monitoring; however, such initiatives pose a challenge for developing countries due to a lack of high quality in situ information. Our proposed methodology could help developing countries bridge this gap by demonstrating the potential to quantify patterns of dry season rice production in Bangladesh. To analyze approximately 90,000 km2 of cultivated land in Bangladesh at 30 m spatial resolution, we used two decades of remote sensing data from the Landsat archive and Google Earth Engine (GEE), a cloud-based geospatial data analysis platform built on Google infrastructure and capable of processing petabyte-scale remote sensing data. We reconstructed the seasonal patterns of vegetation indices (VIs) for each pixel using a harmonic time series (HTS) model, which minimizes the effects of missing observations and noise. Next, we combined the seasonality information of VIs with our knowledge of rice cultivation systems in Bangladesh to delineate rice areas in the dry season, which are predominantly hybrid and High Yielding Varieties (HYV). Based on historical Landsat imagery, the harmonic time series of vegetation indices (HTS-VIs) model estimated 4.605 million ha, 3.519 million ha, and 4.021 million ha of rice production for Bangladesh in 2005, 2010, and 2015 respectively. Fine spatial scale information on HYV rice over the last 20 years will greatly improve our understanding of double-cropped rice systems, current status of production, and potential for HYV rice adoption in Bangladesh during the dry season.

    The microstructure and chemical properties of industrial Portland cement clinkers have been examined by SEM and XRF methods to establish the nature of the clinkers and how variations in the clinker characteristics can be used to control the clinker quality. The clinker nodules were found to show differences in the chemical composition and microstructure between the inner and outer parts of the clinker nodules. Microstructure studies of industrial Portland cement clinker have shown that the outer part of the nodules are enriched in silicate more than the inner part. There is better crystallization and larger alite crystal size in the outer part than in the inner part. The alite crystal size varied between 16.2 -46.12 μ m. The clinker chemical composition was found to affect the residual >45 μ m, where a higher belite content causes an increase in the residual >45 μ m in the the cement product and will cause a decrease in the concrete strength of the cement product. The aluminate and ferrite crystals and the microcracks within the alite crystal are clear in some clinker only. The quality of the raw material preparation, burning and cooling stages can be controlled using the microstructure of the clinker product

    Surface reflectance adjusted for atmospheric effects is a primary input for land cover change detection and for developing many higher level surface geophysical parameters. With the development of automated atmospheric correction algorithms, it is now feasible to produce large quantities of surface reflectance products using Landsat images. Validation of these products requires in situ measurements, which either do not exist or are difficult to obtain for most Landsat images. The surface reflectance products derived using data acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS), however, have been validated more comprehensively. Because the MODIS on the Terra platform and the Landsat 7 are only half an hour apart following the same orbit, and each of the 6 Landsat spectral bands overlaps with a MODIS band, good agreements between MODIS and Landsat surface reflectance values can be considered indicators of the reliability of the Landsat products, while disagreements may suggest potential quality problems that need to be further investigated. Here we develop a system called Landsat-MODIS Consistency Checking System (LMCCS). This system automatically matches Landsat data with MODIS observations acquired on the same date over the same locations and uses them to calculate a set of agreement metrics. To maximize its portability, Java and open-source libraries were used in developing this system, and object-oriented programming (OOP) principles were followed to make it more flexible for future expansion. As a highly automated system designed to run as a stand-alone package or as a component of other Landsat data processing systems, this system can be used to assess the quality of essentially every Landsat surface reflectance image where spatially and temporally matching MODIS data are available. The effectiveness of this system was demonstrated using it to assess preliminary surface reflectance products derived using the Global Land Survey (GLS) Landsat

    2012-01-01

    Incremental Support vector machine (ISVM) is a new learning method developed in recent years based on the foundations of statistical learning theory. It is suitable for the problem of sequentially arriving field data and has been widely used for product quality prediction and production process optimization. However, the traditional ISVM learning does not consider the quality of the incremental data which may contain noise and redundant data; it will affect the learning speed and accuracy to a great extent. In order to improve SVM training speed and accuracy, a modified incremental support vector machine (MISVM) is proposed in this paper. Firstly, the margin vectors are extracted according to the Karush-Kuhn-Tucker (KKT) condition; then the distance from the margin vectors to the final decision hyperplane is calculated to evaluate the importance of margin vectors, where the margin vectors are removed while their distance exceed the specified value; finally, the original SVs and remaining margin vectors are used to update the SVM. The proposed MISVM can not only eliminate the unimportant samples such as noise samples, but also can preserve the important samples. The MISVM has been experimented on two public data and one field data of zinc coating weight in strip hot-dip galvanizing, and the results shows that the proposed method can improve the prediction accuracy and the training speed effectively. Furthermore, it can provide the necessary decision supports and analysis tools for auto control of product quality, and also can extend to other process industries, such as chemical process and manufacturing process.

    The consumption of fresh-cut agricultural produce in Korea has been growing. The browning of fresh-cut vegetables that occurs during storage and foreign substances such as worms and slugs are some of the main causes of consumers' concerns with respect to safety and hygiene. The purpose of this study is to develop an on-line system for evaluating quality of agricultural products using hyperspectral imaging technology. The online evaluation system with single visible-near infrared hyperspectral camera in the range of 400 nm to 1000 nm that can assess quality of both surfaces of agricultural products such as fresh-cut lettuce was designed. Algorithms to detect browning surface were developed for this system. The optimal wavebands for discriminating between browning and sound lettuce as well as between browning lettuce and the conveyor belt were investigated using the correlation analysis and the one-way analysis of variance method. The imaging algorithms to discriminate the browning lettuces were developed using the optimal wavebands. The ratio image (RI) algorithm of the 533 nm and 697 nm images (RI533/697) for abaxial surface lettuce and the ratio image algorithm (RI533/697) and subtraction image (SI) algorithm (SI538-697) for adaxial surface lettuce had the highest classification accuracies. The classification accuracy of browning and sound lettuce was 100.0% and above 96.0%, respectively, for the both surfaces. The overall results show that the online hyperspectral imaging system could potentially be used to assess quality of agricultural products.

    The main payload of the ESA Earth Explorer CryoSat satellite is a Ku band pulse-width limited radar altimeter, operating in 3 different modes function of a mask of geographical zones. Over the ocean and ice sheet interiors, CryoSat mainly operates like a conventional pulse-limited radar altimeter whereas over sea ice, coherently transmitted echoes are combined in order to carry out measurements at a higher resolution. Around ice sheet margins, a 2nd antenna is used as an interferometer in order to determine the across-track angle to the earliest radar returns. Two kinds of data are distributed to the scientific user community and are quality controlled and validated by ESA/ESRIN SPPA office with the support of an industrial consortium: the Level 1b products essentially contain average echoes collected along the ground track while the Level 2 products contain elevations and associated geophysical parameters retrieved from these echoes. In this poster we first briefly present the characteristics of Level 1b and Level 2 CryoSat products over ocean, land ice and sea ice in addition to the results of recent quality control activities. Due to anomalies detected in previous data release and the need of continuously improving the data quality, ESA and its industrial partners has implemented a new version of the processors by the early of 2015, followed by a full reprocessing campaign. The main evolutions of this so called "Baseline C", the validation of the associated Test Data Set and the main improvements expected from this new release are also presented.

    American grocery shoppers face an array of front of pack (FOP) nutrition and health claims when making food selections. Such systems have been categorized as summary or nutrient specific. Either type should help consumers make judgments about the nutrition quality of a product. This research tests if the type or quantity of FOP claims are indeed good indicators of objective nutrition quality. Claim and nutrition information from more than 2200 breakfast cereals and prepared meals launched between 2006 and 2010 were analyzed using binary and multinomial logistic regression models. Results suggest that no type or number of front of pack claims could distinguish "healthy" foods. However, some types and frequencies of FOP claims were significant predictors of higher or lower levels of certain key nutrients. Given the complex and crowded label environment in which these FOP claims reside, one may be concerned that such cues are not closely related to objective measures of nutrition quality. © 2015 Institute of Food Technologists®

    Full Text Available At present, industrial business competition causes producers to be aware of quality, price, and variety in developing new products to meet the consumers' needs. This research reviewed the literature on green marketing and proposes a new conceptual framework of customer loyalty. It uses four constructs—perceived quality, perceived risk, customer trust, and customer loyalty—in the context of environmentally friendly electronics products in Thailand. This research employed an empirical study using the questionnaire survey method to verify the hypotheses. Data were obtained from 420 consumers who bought and used environmentally friendly electronic products, particularly mobile phones, computers, and laptops using a purposive sampling method. The data were analyzed using confirmatory factor analysis (CFA and structural equation modeling (SEM. The results showed that perceived risk and customer trust had a direct effect on customer loyalty while perceived quality had an indirect effect on customer loyalty via customer trust. Furthermore, perceived quality had direct effects on perceived risk and customer trust. The results from the final SEM model were used to confirm the proposed relationships among the variables.

    The Windscale Vitrification Plant (WVP) is owned and operated by British Nuclear Fuels (BNFL) at the Sellafield Site in England. The purpose of the facility is to condition the high level liquid waste, resulting from the reprocessing of spent fuel into a suitable solid form for ultimate disposal. The form chosen is a borosilicate glass matrix which meets both the needs of long term durability and plant operability. A considerable amount of work has now been carried out in order to demonstrate that product quality can be guaranteed through process control. This work has ranged from very small scale lab. studies to full scale production plant trials. WVP entered active service in July 1990 and is currently dealing with the arisings from over 30 years of reprocessing

    Defining the quality of the university education system is not easy. Institutions of higher education, through curriculum are hoped to provide the knowledge, wisdom and personality of students. It is questionable of how far Quality and Productivity Improvement Program (PPKP) are capable to ensure the courses offered relevant and effective in preparing the students for job market. The effectiveness of a university to undertake responsibilities and the impact given to students even after they graduate can be a measure of education quality at university. So, the quality of education can be enhanced and improved from time to time. In general, this study is aims to determine the effectiveness of PPKP's education system from the perspective of their alumni as well as their satisfaction and the importance level based on how PPKP be able to meet their needs. In overall, summary of open-ended questions from the questionnaire, Importance-Performance analysis and correlation analysis were conducted for this study. Based on result, it appears that there are still some deficiencies that can be improve, particularly in terms of teaching skills and PPKP's relationships with external organizations to enable knowledge be channel effectively. Importance-Performance analysis highlights some topics or courses that should be offered by PPKP based on their importance in industrial practice. Summary of the results of correlation analysis was found that women are more positive and not too demanding compared to men. In addition, it is found that the responsibilities and workload of the older generations, higher income and a high level of experience demands them to use and practice what they have learned during their studies at PPKP. Results of this study are hoped could be used to improve the quality of education system at PPKP.

    2017-02-01

    Continuous manufacturing is currently being seriously considered in the biopharmaceutical industry as the possible new paradigm for producing therapeutic proteins, due to production cost and product quality related benefits. In this study, a monoclonal antibody producing CHO cell line was cultured in perfusion mode and connected to a continuous affinity capture step. The reliable and stable integration of the two systems was enabled by suitable control loops, regulating the continuous volumetric flow and adapting the operating conditions of the capture process. For the latter, an at-line HPLC measurement of the harvest concentration subsequent to the bioreactor was combined with a mechanistic model of the capture chromatographic unit. Thereby, optimal buffer consumption and productivity throughout the process was realized while always maintaining a yield above the target value of 99%. Stable operation was achieved at three consecutive viable cell density set points (20, 60, and 40 × 10 6 cells/mL), together with consistent product quality in terms of aggregates, fragments, charge isoforms, and N-linked glycosylation. In addition, different values for these product quality attributes such as N-linked glycosylation, charge variants, and aggregate content were measured at the different steady states. As expected, the amount of released DNA and HCP was significantly reduced by the capture step for all considered upstream operating conditions. This study is exemplary for the potential of enhancing product quality control and modulation by integrated continuous manufacturing. Biotechnol.

    My assertion is that not only are product lines a relevant research topic, but that the tools used by empirical software engineering researchers can address observed practical problems. Our experience at NASA has been there are often externally proposed solutions available, but that we have had difficulties applying them in our particular context. We have also focused on return on investment issues when evaluating product lines, and while these are important, one can not attain objective data on success or failure until several applications from a product family have been deployed. The use of the Quality Improvement Paradigm (QIP) can address these issues: (1) Planning an adoption path from an organization's current state to a product line approach; (2) Constructing a development process to fit the organization's adoption path; (3) Evaluation of product line development processes as the project is being developed. The QIP consists of the following six steps: (1) Characterize the project and its environment; (2) Set quantifiable goals for successful project performance; (3) Choose the appropriate process models, supporting methods, and tools for the project; (4) Execute the process, analyze interim results, and provide real-time feedback for corrective action; (5) Analyze the results of completed projects and recommend improvements; and (6) Package the lessons learned as updated and refined process models. A figure shows the QIP in detail. The iterative nature of the QIP supports an incremental development approach to product lines, and the project learning and feedback provide the necessary early evaluations.

  18. The centralised production and quality control of radiopharmaceuticals

    International Nuclear Information System (INIS)

    Boyd, R.E.

    1980-01-01

    The concept of a centralised facility for the production testing and distribution within a metropolitan, regional or national area, although not new, is now gaining widespread acceptance in many countries. The rationalisation of resources and operation on a large scale ensures savings in costs. The aim of the centralised radiopharmacy is the regular and routine provision of high quality radiopharmaceuticals and to do this it must have access to a multidisciplinary group of scientists working with the support of trained technicians. These specialists require working facilities which are quite unique and designed according to complex engineering criteria to ensure the safety both of the environment and the patient. Production processes and equipment must be selected on the basis of reliability, minimal operational skill and the ease of maintenance. The infra structure of the organisation must provide the logistic support to ensure that the products from the centralized radiopharmacy reach the end-users at the times, places and in the amounts requested. This should be achieved with a success rate which engenders confidence. The Australian Atomic Energy Commission has operated a national radiopharmacy for more than a decade, delivering more than 150000 patient doses per year over the vast distances which separate the Australian capital cities. These activities have helped nuclear medicine to flourish in Australia; it is expected that the creation of the radioisotope production facilities at PUSPATI will have the same effect in Malaysia.

    This application paper presents a machine vision solution for the quality inspection of flat glass products. A contact image sensor (CIS) is used to generate digital images of the glass surfaces. The presented machine vision based quality inspection at the end of the production line aims to classify five different glass defect types. The defect images are usually characterized by very little `image structure', i.e. homogeneous regions without distinct image texture. Additionally, these defect images usually consist of only a few pixels. At the same time the appearance of certain defect classes can be very diverse (e.g. water drops). We used simple state-of-the-art image features like histogram-based features (std. deviation, curtosis, skewness), geometric features (form factor/elongation, eccentricity, Hu-moments) and texture features (grey level run length matrix, co-occurrence matrix) to extract defect information. The main contribution of this work now lies in the systematic evaluation of various machine learning algorithms to identify appropriate classification approaches for this specific class of images. In this way, the following machine learning algorithms were compared: decision tree (J48), random forest, JRip rules, naive Bayes, Support Vector Machine (multi class), neural network (multilayer perceptron) and k-Nearest Neighbour. We used a representative image database of 2300 defect images and applied cross validation for evaluation purposes.

    Full Text Available Abstract Use of the prediction technologies is one of the directions of the research work carried out both in Russia and abroad. Meat processing is accompanied by the complex physico-chemical, biochemical and mechanical processes. To predict the behavior of meat raw material during the technological processing, a complex of physico-technological and structural-mechanical indicators, which objectively reflects its quality, is used. Among these indicators are pH value, water binding and fat holding capacities, water activity, adhesiveness, viscosity, plasticity and so on. The paper demonstrates the influence of animal proteins (beef and pork on the physico-chemical and functional properties before and after thermal treatment of minced meat made from meat raw material with different content of the connective and fat tissues. On the basis of the experimental data, the model (stochastic dependence parameters linking the quantitative resultant and factor variables were obtained using the regression analysis, and the degree of the correlation with the experimental data was assessed. The maximum allowable levels of meat raw material replacement with animal proteins (beef and pork were established by the methods of mathematical programming. Use of the information technologies will significantly reduce the costs of the experimental search and substantiation of the optimal level of replacement of meat raw material with animal proteins (beef, pork, and will also allow establishing a relationship of product quality indicators with quantity and quality of minced meat ingredients.

    Full Text Available Product quality has been and will remain one of the most important indicators of increasing economic and financial performance of a company. Quality is that which ensures the greatest part of the competitiveness of a product or service, this being the result of some important aspects such as: products and services of quality to meet consumers requirements, low costs without affecting the quality level, the performance of contractual obligations, customer satisfaction and last but not least obtaining profit. Research and results concerning this issue will result in the prerequisites in the process for quality assurance that can develop both internally and externally. The purpose of this article lies in the approach and illustration of the aspects of products differentiated and non-differentiated in quality classes. In launching this research I will try to highlight some aspects that most efficiently the indicators mentioned above, indicators that read to what extent a certain product meets the characteristics specified to its destination.

    The efforts to improve and optimize productivity of dairy cows require sufficient availability of nutrients, especially high energy in the early period of lactation. Increasing energy intake in dairy cows can be conducted by increasing the density of energy. The research aimed to evaluate dietary protected feed supplement on milk production and quality, including: fat, protein, and lactose content of Friesian Holstein dairy cow milk. Protected feed supplement was produced from sardine fish oil, through saponification and microencapsulation protection methods. The experiment consists of two treatments i.e. P0: basal diet (control) and P1: basal diet + 3 % protected feed supplement. Each treatment was repeated 15 times. Data were analyzed by independent samples t-test analysis. Results showed that supplementation of protected sardine fish oil had no effect on lactose content, but increased milk yield production (pmilk fat content (p<0.05), and protein content (p<0.05).

    Full Text Available The paper gives a brief overview of the current nutritional status of the Ukrainian population and describes useful buckwheat properties. The objective of the paper is to study the effect of buckwheat processing products (flour and flakes on the technological process and quality of bread made from whole-wheat flour. This paper describes and analyzes research data on the rheological properties of dough samples which were determined by farinograph and amylograph. Investigation of structural and mechanical properties of dough showed an increase in water-absorbing capacity in all samples when adding buckwheat products. Moreover, dough made with buckwheat flakes has a lower value of mixing tolerance index (by 47 % than dough made from buckwheat flour, and a higher valorimetric value (by 20 %. Determination of dough properties by amylogram has shown that a sample containing buckwheat flakes has a higher maximum viscosity than a sample containing buckwheat flour. Determination of the gas-production and gas-retention capacity of dough is also presented, along with an analysis of the quality of finished products based on the results of laboratory baking tests. The samples of bread supplemented with buckwheat flakes have better shape stability (by 21 %, specific volume (by 12 % and porosity (by 11 % than bread made from buckwheat flour. The organoleptic evaluation of finished product quality has shown that bread supplemented with buckwheat flakes has a more fluffy-texture, elastic crumb and uniform porosity than bread made from buckwheat flour. Buckwheat flakes proved to have a better effect on parameters of the technological process and quality of bread when compared with buckwheat flour.

    Since the 1990ties, agricultural land in use in Norway has diminished and yields per hectare for cereals and forages have stagnated. An expert panel appointed to advice on how to increase Norwegian grain production emphasizes low profitability and poor soil quality as limiting factors. A White Paper from the Norwegian Government, Report No.9 (2011-2012), stated that the main goal for the agricultural sector is to increase food production proportional to the expected increase in population (20 % by 2030) in order to maintain self-sufficiency at the present level. This is the background for the interdisciplinary project AGROPRO "Agronomy for increased food production - Challenges and solutions" (2013 - 2017)" financed by the Norwegian research council. A mail goal is seeking possibilities for improvements in agronomic practices for increased and sustainable food production and to identify drivers and challenges for their implementation. Are the key to higher yields hidden in the soil? The paper present an overview of the research activities in the project and some results of the improvements of soil quality to minimize yield gap in cereal and forage production. Detailed new soil maps provide soil information on field scale of soil quality and the suitability for growing different crops like cereal production or vegetables. The detailed soil information is also beeing used for development and adaptation of the planning tool «Terranimo» to reduce risk of soil compaction.The farmer get available soil information for each field, provide information about the maschinery in use- tractors and equipment, tyres, pressure. The decision tool evaluate when the soil is suitable for tillage, calculate the risk of compaction for dry, moist and wet soil. New research data for compaction on Norwegian clay and silt soil are included. Climate change with wetter conditions gives challenges for growing cereals. The project is testing genetic variation in cereals for tolerance to water

    Traditional alcoholic beverages of Tanzania play an important role in the daily social, economic, nutritional and cultural life of the people. Production, quality and changes in quality attributes during ambient temperature storage were investigated in traditional Tanzanian beers (Mbege and Komoni) and wines (Mnanasi, Wanzuki and Mofru). The quality attributes of the alcoholic beverages indicated that pH levels were in the range of 4.15-4.20 and 3.9-5.5 for the beers and wines respectively. Total, fixed and volatile acidity in the beers were in the range of 0.41-0.62, 0.28-0.38 and 0.06-0.09 g/100 mL respectively while in the wines acidity levels were in the range of 0.23-0.66, 0.13-0.33 and 0.05-0.06 g/100 mL for the total, fixed and volatile acidity respectively. Concentration of total solids in the beers ranged between 7.00 and 12.80 degrees Brix while in the wines ranged between 3.45 and 6.65 degrees Brix. Specific gravity of the beers ranged between 1.0097 and 1.0374 while for wines the specific gravity was lower, ranging between 0.9971 and 0.9989. Alcohol concentration was higher in wines (range 3.84-9.75 g/100 mL) than in beers (range 1.72-2.76 g/100 mL). Storage of the beverages under ambient temperatures for various lengths of time resulted in significant (P beers indicated the highest rates of deterioration with total acid production rates of 0.3774 g/100 mL and 0.0914 g/100 mL per hour respectively. Wines were more stable during storage than beers, with Mofru wine being the most stable. The rates of total acid production per hour were Mnanasi (0.0196 g/100 mL), Wanzuki (0.0047 g/100 mL) and Mofru (0.0005 g/100 mL). Use of low brewing technologies involving uncontrolled fermentation, unsanitary conditions and use of rudimentary equipment for processing, packaging and storage resulted in beers and wines of low quality and short shelf-life. To foster commercial exploitation of the products, there is a need to develop appropriate small and medium

    2017-04-01

    Global Precipitation Mission brings major improvement to rainfall measurement system. Related precipitation products are delivered with a temporal and spatial resolution compliant with flash floods modeling. However assessing the accuracy of these products on extreme rainfall events is still an open issue. Two kinds of significant events are presented: Sahelian squall lines and orographic enhanced convective systems on Maghreb. The 2016 rainy season on Sahel has been above normal and the retrieval quality of two huge precipitation systems (14th June and 13th July) is investigated. On end of September 2016 northern Tunisia experimented severe floods produced by two series of local convective systems. Although IMERG products are globally consistent some discrepancies appear. The mean bias seem linked with orographic lifting. It is obvious in Tunisia case but should not be neglected even in Sahelian squall line. On an other side, at the high temporal resolution scale, IMERG estimation does not match perfectly with geostationary IR data. These observations raise the issue of defining a proper downscaling process from the full flow of GPM data.

    Abiotic and biotic stresses reduce plant productivity, yet high-throughput characterization of plant responses across genotypes, species and stress conditions are limited by both instrumentation and data analysis techniques. Recent developments in chlorophyll a fluorescence measurement at leaf to landscape scales could improve our predictive understanding of plants response to stressors. We analyzed the interaction of species and stress across two crop types, five gymnosperm and two angiosperm tree species from boreal and montane forests, grasses, forbs and shrubs from sagebrush steppe, and 30 tree species from seasonally wet tropical forest. We also analyzed chlorophyll fluorescence and gas exchange data from twelve Brassica rapa crop accessions and 120 recombinant inbred lines to investigate phenotypic responses to drought. These data represent more than 10,000 measurements of fluorescence and allow us to answer two questions 1) are the measurements from high-throughput, hand held and drone-mounted instruments quantitatively similar to lower throughput camera and gas exchange mounted instruments and 2) do the measurements find differences in genotypic, species and environmental stress on plants? We found through regression that the high and low throughput instruments agreed across both individual chlorophyll fluorescence components and calculated ratios and were not different from a 1:1 relationship with correlation greater than 0.9. We used hierarchical Bayesian modeling to test the second question. We found a linear relationship between the fluorescence-derived quantum yield of PSII and the quantum yield of CO2 assimilation from gas-exchange, with a slope of ca. 0.1 indicating that the efficiency of the entire photosynthetic process was about 10% of PSII across genotypes, species and drought stress. Posterior estimates of quantum yield revealed that drought-treatment, genotype and species differences were preserved when accounting for measurement uncertainty

    To analyze the effects of nutritional intervention with a milk product enriched with soy isoflavones on quality of life and bone metabolism in postmenopausal Spanish women. We performed a double-blind controlled randomized trial in ninety-nine postmenopausal women. Group S women (n=48) were randomized to consume milk product enriched with soy isoflavone (50 mg/day) while group C (n=51) consumed product control for 12 months. Parameters of quality of life (Cervantes scale), markers of bone metabolism and bone mass estimated by ultrasound of the calcaneus (QUS) were evaluated. Overall, there was an improvement in the domains menopause (P=.015) and vasomotor symptoms (Pmilk products increases levels of 25-OH-vitamin D and decreases bone metabolism markers. Additional supplementation with soy isoflavones seems to improve quality of life and bone mass in Spanish postmenopausal women. Copyright © 2010 Elsevier España, S.L. All rights reserved.

    Full Text Available The production system using cages is a highly polemical issue in Europe, because of the space restriction imposed to laying hens. It is considered that the cage system might compromise important comfort movements, welfare and egg quality. This study evaluated egg quality and welfare of two strains of hens housed in a conventional system (battery laying cages or litter system with nest and perches, and submitted to heat stress or comfort conditions. Two groups of 20 birds (10 Hy-line W36 and 10 Hy-line Brown were submitted to two environmental conditions (26°C and 60% RH or 35°C and 70% RH and two housing systems (cages or litter in the early production phase. Egg quality was analyzed based on egg weight, eggshell thickness, specific gravity, and Haugh units. Yolk and shell contamination by Salmonella sp was also assessed. A significant (p<0.05 reduction in quality parameters was observed in eggs produced by laying hens under heat stress, mainly in the birds housed in cages.

  17. Confectionery products (halva type obtained from sunflower: production technology and quality alterations. A review

    Directory of Open Access Journals (Sweden)

    Mureşan, V.

    2013-01-01

    Full Text Available Sunflower "halva" is a popular and widely enjoyed confectionery product specific to the countries of Eastern Europe. Conventional halva has historically been produced from sesame seeds in the Middle East and Northern Africa. However, in the production of halva in Eastern Europe, sesame seeds have been largely replaced by sunflower seeds, due to the high availability of sunflower in this region and the comparable taste of the final product. Due to the importance of the cost of raw materials in the food industry, utilization of sunflower seeds in halva production may be of great interest worldwide because it offers the possibility of significantly lowering production costs. Nevertheless, oil separation and storage techniques must be perfected if sunflower halva is to fulfill its promise of becoming a cost effective alternative to sesame seed halva on a worldwide scale. The aims of this review are firstly, to describe the current state of sunflower halva technology, secondly, to isolate the main problems affecting the quality of the final product, and thirdly, to suggest areas of further research necessary to move sunflower halva production closer to reaching its full potential on the world market.

    Oilseed crops are used to produce vegetable oil. Sesame (Sesamum indicum), an oilseed crop grown worldwide, has high oil content and a small diploid genome, but the genetic basis of oil production and quality is unclear. Here we sequence 705 diverse sesame varieties to construct a haplotype map of the sesame genome and de novo assemble two representative varieties to identify sequence variations. We investigate 56 agronomic traits in four environments and identify 549 associated loci. Examination of the major loci identifies 46 candidate causative genes, including genes related to oil content, fatty acid biosynthesis and yield. Several of the candidate genes for oil content encode enzymes involved in oil metabolism. Two major genes associated with lignification and black pigmentation in the seed coat are also associated with large variation in oil content. These findings may inform breeding and improvement strategies for a broad range of oilseed crops. PMID:26477832

    The department of Applied Acoustics teaches engineering and architect students at Chalmers University of Technology. The teaching of room acoustics to architectural students has been under constant development under several years and is now based on the study of room acoustics as a product sound quality issue. Various listening sessions using binaural sound recording and reproduction is used to focus students' learning on simple, easy to remember concepts. Computer modeling using ray tracing software and auralization is also used extensively as a tool to demonstrate concepts in addition to other software for simple sound generation and manipulation. Sound in general is the focus of an interdisciplinary course for students from Chalmers as well as from a school of art, a school of design, and a school of music which offers particular challenges and which is almost all listening based.

    Frank Neumann focuses on establishing a theoretical basis that allows a description of the interplay between individual and collective processes in product development. For this purpose, he introduces the integrated descriptive model of knowledge creation as the first constituent of his research framework. As a second part of the research framework, an analysis and modeling method is proposed that captures the various knowledge conversion activities described by the integrated descriptive model of knowledge creation. Subsequently, this research framework is applied to the analysis of knowledge characteristics of mechatronic product development (MPD). Finally, the results gained from the previous steps are used within a design support system that aims at federating the information and knowledge resources contained in the models published in the various development activities of MPD.

    Quality control (QC) validation is an essential tool in total quality management of a veterinary clinical pathology laboratory. Cost-analysis can be a valuable technique to help identify an appropriate QC procedure for the laboratory, although this has never been reported in veterinary medicine. The aim of this study was to determine the applicability of the Six Sigma Quality Cost Worksheets in the evaluation of possible candidate QC rules identified by QC validation. Three months of internal QC records were analyzed. EZ Rules 3 software was used to evaluate candidate QC procedures, and the costs associated with the application of different QC rules were calculated using the Six Sigma Quality Cost Worksheets. The costs associated with the current and the candidate QC rules were compared, and the amount of cost savings was calculated. There was a significant saving when the candidate 1-2.5s, n = 3 rule was applied instead of the currently utilized 1-2s, n = 3 rule. The savings were 75% per year (£ 8232.5) based on re-evaluating all of the patient samples in addition to the controls, and 72% per year (£ 822.4) based on re-analyzing only the control materials. The savings were also shown to change accordingly with the number of samples analyzed and with the number of daily QC procedures performed. These calculations demonstrated the importance of the selection of an appropriate QC procedure, and the usefulness of the Six Sigma Costs Worksheet in determining the most cost-effective rule(s) when several candidate rules are identified by QC validation. © 2014 American Society for Veterinary Clinical Pathology and European Society for Veterinary Clinical Pathology.

    Full Text Available The goal of the present study was to evaluate the influence of increasing levels of dietary calcium on performance, egg quality, and the amount of calcium retained in the meat and excreted by Japanese quails at the final production. Four hundred 46-58-week-old Japanese quails were distributed in a completely randomized design consisting of five calcium level treatments: T1 = 2.95%, T2 = 3.25%, T3 = 3.55%, T4 = 3.85% and T5 = 4.15% calcium. The performance variables included feed intake (g bird-1 day-1, egg production (%, feed conversion by egg mass and per dozen eggs, egg mass (g, and viability. For egg quality, we assessed egg weight, percentage of albumen, yolk weight, percentage of shell, and shell thickness. We also evaluated the amount of calcium present in the meat and the amount of calcium excreted by quails. Increasing levels of calcium linearly influenced feed conversion, weight of yolk, and percentage of eggshell. Shell thickness increased up to the 3.85% calcium treatment. Calcium content of the meat differed among the quails; the quails fed the lowest level of calcium (2.95% showed higher calcium content in meat, whereas calcium excretion increased with increasing levels of calcium in the diet. In conclusion, the addition of 3.85% of calcium in quail feed at the end of production improved eggshell quality, and maintained internal quality and performance within the recommended standards for the production phase tested in quails. Levels higher than 3.85% calcium negatively influenced the parameters analyzed.

  6. Analyzing key constraints to biogas production from crop residues and manure in the EU—A spatially explicit model

    Persson, U. Martin

    2017-01-01

    This paper presents a spatially explicit method for making regional estimates of the potential for biogas production from crop residues and manure, accounting for key technical, biochemical, environmental and economic constraints. Methods for making such estimates are important as biofuels from agricultural residues are receiving increasing policy support from the EU and major biogas producers, such as Germany and Italy, in response to concerns over unintended negative environmental and social impacts of conventional biofuels. This analysis comprises a spatially explicit estimate of crop residue and manure production for the EU at 250 m resolution, and a biogas production model accounting for local constraints such as the sustainable removal of residues, transportation of substrates, and the substrates’ biochemical suitability for anaerobic digestion. In our base scenario, the EU biogas production potential from crop residues and manure is about 0.7 EJ/year, nearly double the current EU production of biogas from agricultural substrates, most of which does not come from residues or manure. An extensive sensitivity analysis of the model shows that the potential could easily be 50% higher or lower, depending on the stringency of economic, technical and biochemical constraints. We find that the potential is particularly sensitive to constraints on the substrate mixtures’ carbon-to-nitrogen ratio and dry matter concentration. Hence, the potential to produce biogas from crop residues and manure in the EU depends to large extent on the possibility to overcome the challenges associated with these substrates, either by complementing them with suitable co-substrates (e.g. household waste and energy crops), or through further development of biogas technology (e.g. pretreatment of substrates and recirculation of effluent).

    Wu, M.; Demissie, Y.; Yan, E.

    2010-12-01

    The impact of increased biofuel feedstock production on regional water quality was examined. This study focused on the Upper Mississippi River Basin, from which a majority of U.S. biofuel is currently produced. The production of biofuel from both conventional feedstock and cellulosic feedstock will potentially increase in the near future. Historically, this water basin generates the largest nitrogen loading to the waterway in the United States and is often cited as a main contributor to the anoxic zone in the Gulf of Mexico. To obtain a quantitative and spatial estimate of nutrient burdens at the river basin, a SWAT (Soil and Water Assessment Tool) model application was developed. The model was equipped with an updated nutrient cycle feature and modified model parameters to represent current crop and perennial grass yield as a result of advancements in breeding and biotechnology. Various biofuel feedstock production scenarios were developed to assess the potential environmental implications of increased biofuel production through corn, agriculture residue, and perennial cellulosic feedstock (such as Switchgrass). Major factors were analyzed, including land use changes, feedstock types, fertilizer inputs, soil property, and yield. This tool can be used to identify specific regional factors affecting water quality and examine options to meet the requirement for environmental sustainability, thereby mitigating undesirable environmental consequences while strengthening energy security.

    Talyta Galafassi Zarpelon

    Full Text Available Abstract Plant growth-promoting rhizobacteria strains from special formulations have been used to optimize eucalyptus cutting production. To undertake quality control for the formulated products, the rhizobacterial strains should be characterized to assess their purity and authentication. In the present study, we characterized nine strains of rhizobacteria, including three Bacillus subtilis (S1, S2 and 3918, two Pseudomonas sp. (MF4 and FL2, P. putida (MF2, P. fulva (Ca, Frateuria aurantia (R1, and Stenotrophomonas maltophilia (CIIb. The strains were differentiated by colony morphology after 24 h of incubation in three different solid state culture media (glucose-nutritive agar, 523 medium and yeast extract-mannitol agar, sensitivity to a panel of 28 antibiotics (expressed according to the formation of inhibition halos of bacterial growth in the presence of antibiotics, and PCR-RFLP profiles of the 16S rDNA gene produced using nine restriction enzymes. It was possible to differentiate all nine strains of rhizobacteria using their morphological characteristics and sensitivity to antibiotics. The molecular analysis allowed us to separate the strains CIIb, FL2 and R1 from the strains belonging to the genera Bacillus and Pseudomonas. By using these three methods concomitantly, we were able to determine strain purity and perform the authentication.

  13. The relationship between product quality and transaction costs with vertical coordination in DOC Rioja wine grape industry

    Fernanez-Olmos, M.; Rossell-Martinez, J.; Espitia-Escuer, M. A.

    2009-07-01

    This paper analyzes the relationship between product quality and governance mode choice (market mode, hybrid mode or vertical integration) using the results of a survey of 187 qualified appellation of origin (DOC) Rioja wineries. By estimating a generalized ordered logit, it is concluded that wineries that produce high-quality wines are more likely to vertically integrate than are wineries that produce low-quality wines. Consistent with transaction cost economics, evidence is found that asset specificity and uncertainty are important determinants of vertical integration. Finally, the size of the winery is also an important factor that affects governance mode choice in viticulture. (Author)

    Full Text Available Four homemade (artisanally manufactured and unrecorded and seven commercial (industrially manufactured and taxed alcohol products from Vietnam were collected and chemically analyzed for toxicologically relevant substances. The majority of both types had alcohol contents between 30 and 40% vol. Two homemade samples contained significantly higher concentrations of 45 and 50% vol. In one of these homemade samples the labeled alcoholic strength was exceeded by nearly 20% vol. All other analyzed constituents of the samples (e.g., methanol, acetaldehyde, higher alcohols, esters, metals, anions were found in concentrations that did not pose a threat to public health. A peculiarity was a homemade sample of alcohol with pickled snakes and scorpions that contained 77% vol of alcohol, allegedly used as traditional Chinese medicine. Based on this small sample, there is insufficient evidence to conclude that alcohol quality, beyond the effects of ethanol, has an influence on health in Vietnam. However, future research with larger samples is needed.

    At present, solving environmental problems in industrially developed regions with a large concentration of mining and machine building enterprises is one of the main socially important tasks. Taking into account the increase in the volume of mining, there is an increase in the environmental burden, which affects the internal migration of the population. This is particularly evident in the examples of single-industry towns, in which a gradual decrease in the young workable population occurs. The article presents an analysis of the sources of maximum pollution of the environment by coal mining enterprises. Modern methods of controlling automobile fuel were analyzed. The analysis of fuel quality and the environmental assessment of combustion products was carried out. The equipment used in the article makes it possible to exclude substandard fuel and to reduce harmful emissions of vehicles to the atmosphere.

    The recharge of the aquifer in the Crau plain (550 km2, Southern Rhone Valley, France) depends on the irrigation of 15000 ha of meadow using water withdrawn from the River Durance through a dense network of channels. Traditional irrigation practice, since the XVIth century, has consisted in flooding the grassland fields with a large amount of water, the excess being infiltrated toward the water table. Today, the Crau aquifer holds the main resource in water in the area (300 000 inhabitants) but changes in the agricultural practices and progressive replacement of the irrigated meadows by urbanized area threaten the sustainability of groundwater. The distributed modeling of irrigated meadows together with the modeling of groundwater has been undertaken for quantifying the contribution of the irrigation to the recharge of the aquifer and to investigate possible evolution of hay production, water drainage, evapotranspiration and water table under scenarios of climate and land-use changes. The model combines a crop model (STICS) that simulates hay production, evapotranspiration and water drainage, a multisimulation tool (MultiSimLib) that allows to run STICS over each agricultural field in the aquifer perimeter, a groundwater model MODFLOW to simulate the water table from recharge data (simulated drainage). Specific models were developed for simulating the spatial distribution of climate, including scenario of changes for the 2025 - 2035 time period, soil properties (influenced by irrigation), and agricultural practices (calendar and amount), in particular irrigation and hay cutting. This step was crucial for correctly simulating hay production level and amount of water used for irrigation. Model results were evaluated thanks to plot experiments and information from farmers (biomass production, downward water flow, quantity of irrigated water, cutting calendar...), a network of piezometers and remote sensing maps of evapotranspiration. Main results included: - the

    The code SORS was written by General Atomic to calculate the release of fission products from the fuel into the primary coolant during a hypothetical uncontrolled transient temperature excursion. The code assumes that the graphite core remains structurally intact. The release from the fuel particles is calculated using a coarse time step for several sections of the core. For the non-volatile elements, the code calculates a diffusion rate and an evaporation rate in each section of the core. The expression used for the evaporation rate is found to be incompatible with the rest of the assumptions used in the calculation

    1992-03-01

    WINDOW 4.0 is a publicly available IBM PC compatible computer program developed by the Windows and Daylighting Group at Lawrence Berkeley Laboratory for calculating total window thermal performance indices (e.g. U-values, solar heat gain coefficients, shading coefficients, and visible transmittances). WINDOW 4.0 provides a versatile heat transfer analysis method consistent with the rating procedure developed by the National Fenestration Rating Council (NFRC). The program can be used to design and develop new products, to rate and compare performance characteristics of all types of window products, to assist educators in teaching heat transfer through windows, and to help public officials in developing building energy codes. WINDOW 4.0 is a major revision to WINDOW 3.1 and we strongly urge all users to read this manual before using the program. Users who need professional assistance with the WINDOW 4.0 program or other window performance simulation issues are encouraged to contact one or more of the NFRC-accredited Simulation Laboratories. A list of these accredited simulation professionals is available from the NFRC.

    2012-01-01

    With the transformation of its population structure and economic environment, Taiwan is rapidly becoming an aging society. There is a growing need for elderly products, and therefore the operation of web shops that sell elderly products is important. In an era which values performance management, searching for key performance indicators (KPIs) helps to reveal, if the goals of a web shop are achieved. In the current study, researchers adopted the constructs of the Balanced Scorecard (BSC) to evaluate web shop performance. Additionally, the Delphi method, along with questionnaires, was used to develop 29 indicators. Finally, the decision making trial and evaluation laboratory (DEMATEL) method assisted in identifying the level of importance of the constructs, in which "internal process" ranked top, followed by "learning and growth", "customer", and "financial". "Internal process" was the key construct that impacted other factors, while "customer" was an important construct affected by other factors. By understanding the influences and relationships among the constructs, enterprises can conduct additional monitoring and management to achieve functions of prevention, continuous improvement, and innovation in order to shape their core competence.

    Tobacco control (TC) research capacity and productivity are critical for developing evidence-informed interventions that will reduce the harmful effects of smoking. The aim of this paper was to investigate New Zealand's (NZ) TC research capacity along with the quantity and quality of publications, following two government initiatives aimed, in part, at improving the quantity and quality of NZ TC research. Scopus was searched for articles with at least one NZ author and where the topic was of primary relevance to TC. Publications were organized into two time periods, following the government initiatives, 1993-2003 and 2004-2009. We analyzed the number of publications, publication journals, type of publications, impact (using the impact factor), and authorship. There has been an increase in number and impact of publications and number of authors. The number of publications has increased from an average of 14 (1994-2003) to 38 per year (2004-2009). The number of journals published increased from 64 to 86. The impact during 2004-2009 was almost threefold than in 1993-2003. The number of authors increased from 212 to 345, and the number of authors who had at least one first-authored publication increased from 80 to 124. These results show an encouraging trend in NZ TC research, with an increase in research productivity, quality, and in research capacity. It is possible that government-initiated and -funded infrastructural support contributed to increasing needed TC research, which supports the worth of such initiatives.

    To assess the role of a Toyota production system (TPS) quality improvement (QI) intervention on appropriateness of perioperative antibiotic therapy and in length of hospital stay (LOS) among surgical patients. Pre-post quasi-experimental study using local and national retrospective cohorts. We used TPS methods to implement a multifaceted intervention to reduce nosocomial methicillin-resistant Staphylococcus aureus infections on a Veterans Affairs surgical unit, which led to a QI intervention targeting appropriate perioperative antibiotic prophylaxis. Appropriate perioperative antibiotic therapy was defined as selection of the recommended antibiotic agents for a duration not exceeding 24 hours from the time of the operation. The local computerized medical record system was used to identify patients undergoing the 25 most common surgical procedures and to examine changes in appropriate antibiotic therapy and LOS over time. Overall, 2550 surgical admissions were identified from the local computerized medical records. The proportion of surgical admissions receiving appropriate perioperative antibiotics was significantly higher (P <.01) in 2004 after initiation of the TPS intervention (44.0%) compared with the previous 4 years (range, 23.4%-29.8%) primarily because of improvements in compliance with antibiotic therapy duration rather than appropriate antibiotic selection. There was no statistically significant decrease in LOS over time. The use of TPS methods resulted in a QI intervention that was associated with an increase in appropriate perioperative antibiotic therapy among surgical patients, without affecting LOS.

    2017-12-01

    The NASA CERES project continues to provide the scientific communities a wide variety of satellite-derived data products such as observed TOA broadband shortwave and longwave observed fluxes, computed TOA and Surface fluxes, as well as cloud, aerosol, and other atmospheric parameters. They encompass a wide range of temporal and spatial resolutions, suited to specific applications. CERES data is used mostly by climate modeling communities but also by a wide variety of educational institutions. To better serve our users, a web-based Ordering and Visualization Tool (OVT) was developed by using Opens Source Software such as Eclipse, java, javascript, OpenLayer, Flot, Google Maps, python, and others. Due to increased demand by our own scientists, we also implemented a series of specialized functions to be used in the process of CERES Data Quality Control (QC) such as 1- and 2-D histograms, anomalies and differences, temporal and spatial averaging, side-by-side parameter comparison, and others that made the process of QC far easier and faster, but more importantly far more portable. With the integration of ground site observed surface fluxes we further facilitate the CERES project to QC the CERES computed surface fluxes. An overview of the CERES OVT basic functions using Open Source Software, as well as future steps in expanding its capabilities will be presented at the meeting.

  14. The Model of the Production Process for the Quality Management

    2017-02-01

    Full Text Available This article is a result of the research on the models of the production processes for the quality management and their identification. It discusses the classical model and the indicators for evaluating the capabilities by taking as its starting point the assumption of the normal distribution of the process characteristics. The division of the process types proposed by ISO 21747:2006 standard introducing models for non-stationary processes is presented. A general process model that allows in any real case to precisely describe the statistical characteristics of the process is proposed. It gives the opportunity for more detailed description, in comparison to the model proposed by ISO 21747:2006 standard, of the process characteristics and determining its capability. This model contains the type of process, statistical distribution, and the method for determining the capability and performance (long-term capability of the process. One of the model elements is proposed, own classification and resulting set of process types. The classification follows the recommendations of ISO 21747:2006 introducing models for the non-stationary processes. However, the set of the process types allows, beyond a more precise description of the process characteristics, its usage to monitor the process.

    2014-04-01

    Full Text Available In Brazil, several research efforts have been done to understand the Management field of study through bibliometric studies. However, these analyses do not consider the quality of publications, but the amount. To avoid this bias, this study proposes to analyze the landscape of publications from Management, through the perspective of quality papers. For this, we used as sample 123 award winning papers of ANPAD congresses (2004 to 2012. The characteristics of these quality papers are: major awarded educational institutions are located on the South-east axis of the country; great part of authors who receive multiple awards, get them from different academic divisions; the proportion of papers written in foreign language is higher among the winning entries; most quality research studies have empirical and quantitative basis. It is suggested that award winning papers can point out quality research production as a complementary to quantity indicators in a performance evaluation system.

    2017-01-01

    Full Text Available The transition from an economy dependent on nonrenewable energy sources to one with higher diversity of renewables will not be a simple process. It requires an important research effort to adapt to the dynamics of the changing energy market, sort costly processes, and avoid overlapping with social interest markets such as food and livestock production. In this review, we analyze the desirable traits of raw plant materials for the bioethanol industry and the molecular biotechnology strategies employed to improve them, in either plants already under use (as maize or proposed species (large grass families. The fundamentals of these applications can be found in the mechanisms by which plants have evolved different pathways to manage carbon resources for reproduction or survival in unexpected conditions. Here, we review the means by which this information can be used to manipulate these mechanisms for commercial uses, including saccharification improvement of starch and cellulose, decrease in cell wall recalcitrance through lignin modification, and increase in plant biomass.

    Spruce, Joseph P.; Hargrove, William; Gasser, Jerry; Smoot, James; Kuper, Philip D.

    2014-01-01

    This presentation discusses MODIS NDVI change detection methods and products used in the ForWarn Early Warning System (EWS) for near real time (NRT) recognition and tracking of regionally evident forest disturbances throughout the conterminous US (CONUS). The latter has provided NRT forest change products to the forest health protection community since 2010, using temporally processed MODIS Aqua and Terra NDVI time series data to currently compute and post 6 different forest change products for CONUS every 8 days. Multiple change products are required to improve detectability and to more fully assess the nature of apparent disturbances. Each type of forest change product reports per pixel percent change in NDVI for a given 24 day interval, comparing current versus a given historical baseline NDVI. EMODIS 7 day expedited MODIS MOD13 data are used to obtain current and historical NDVIs, respectively. Historical NDVI data is processed with Time Series Product Tool (TSPT); and 2) the Phenological Parameters Estimation Tool (PPET) software. While each change products employ maximum value compositing (MVC) of NDVI, the design of specific products primarily differs in terms of the historical baseline. The three main change products use either 1, 3, or all previous years of MVC NDVI as a baseline. Another product uses an Adaptive Length Compositing (ALC) version of MVC to derive an alternative current NDVI that is the freshest quality NDVI as opposed to merely the MVC NDVI across a 24 day time frame. The ALC approach can improve detection speed by 8 to 16 days. ForWarn also includes 2 change products that improve detectability of forest disturbances in lieu of climatic fluctuations, especially in the spring and fall. One compares current MVC NDVI to the zonal maximum under the curve NDVI per pheno-region cluster class, considering all previous years in the MODIS record. The other compares current maximum NDVI to the mean of maximum NDVI for all previous MODIS years.

  20. An Evaluation Method of Comprehensive Product Quality for Customer Satisfaction Based on Intuitionistic Fuzzy Number

    2018-01-01

    Full Text Available How to maximize customer satisfaction is an important research topic in the service quality evaluation. This paper proposes an evaluation method of comprehensive product quality for customer satisfaction based on the intuitionistic fuzzy number. In this method, we design a questionnaire and investigate the customer’s language evaluation information of product quality evaluation, including product expectations and product perception at first. And then, the product quality evaluation model is obtained by Delphi method; that is, the first-level evaluation indexes and the second-level evaluation indexes are obtained and the weight vector of each evaluation index is determined. Next, language evaluation information translates into corresponding fuzzy numbers using intuitionistic fuzzy numbers. Therefore, the results of the product quality evaluation of the production system are obtained using the weighted mean method. Finally, an example is used to illustrate the feasibility and effectiveness of the proposed method.

    Full Text Available In the paper there are presented system approaches, applied in Slovak transformed production enterprises, which solve questions of closing the so called industrial cycle from the side of the wastes' producers. The production quality is connected not only with the technological chain itself and with outputs from it - the utility product, but also with the load of the life environment.The presented possibilities of the liquidation of solid energetic waste – fly ashes – represent a an overview of forms and methods of its utilization. By combusting one kind of coal in various boilers, fly ashes with different physical, chemical, and mineralogical properties originate, with the combustion temperature as a dominant factor. The fly ashes are directly (without influencing its composition applied in civil engineering, mining, metallurgy, waste water cleaning, etc. Their utilization after a separation removal of unwanted components is an economically difficult process. Such a unvaluable component is coal combustion residue, evaluated by the annealing loss (carbon-in-ash loss in fly ashes used for special procedures in civil enginering, e.g. in mortars (maximally 4% of c.a.s. loss or in the porous concrete (4-7% of c.a.s. loss. The building industry processes about 20% of solid energetic waste.

    The main objective of the present study was to classify doctoral programs with Quality Mention in Psychology based on their scientific productivity. For this purpose, articles in the Web of Science published by professors teaching in these doctoral programs were analyzed. In addition, we analyzed scientific journals in which these professors tend to publish more papers and the evolution in the number of papers published until 2009. Results showed that the most productive doctoral program was the Neurosciences program at the University of Oviedo. This program showed a ratio of 40 articles--published in journals included in Journal Citation Reports--by each professor. In contrast, other programs did not reach a ratio of 10 articles per professor. Regarding journals, results showed that 9 out of the 20 most popular journals are Hispanic and a gradual increase in the number of published papers was also observed. Lastly, results and implications for quality assessment are discussed.

    Based on experience in clinical trial approvals and marketing authorizations for biosimilar products in Korea, we suggest principles for the analytical comparability assessment of biosimilar products with respect to regulatory considerations. The composition and manufacturing processes of biosimilar products can differ from those of the reference product depending on the information available for the reference product and the time of product development; however, the analytical characteristics of biosimilar products should be highly similar to those of the reference product. Although manufacturing an identical product in terms of the quality profile is nearly impossible due to the high molecular weight and complex structure of biological products, the developer of the biosimilar product should attempt to establish a quality level as similar to that of the reference product as possible. When comparing the similarity of quality attributes, the criticality of the quality attributes and the characteristics of orthogonal quality attributes need to be considered carefully. Based on the results from the analytical comparability assessment, the comparability results of non-clinical and clinical studies should be evaluated before claiming biosimilarity to the reference product. In this review, we focus on quality attribute evaluation based on our regulatory experience. Copyright © 2017 International Alliance for Biological Standardization. Published by Elsevier Ltd.

    Buroni, Federica E; Lodola, Lorenzo; Persico, Marco G; Aprile, Carlo

    2014-02-01

    The aim of the study was to identify deficiencies in product labelling instructions for reconstitution and in the quality control directions detailed in the technical leaflets (TLs) or summary product characteristic (SPC) sheets of commonly used technetium labelling cold kits. The reconstitution and quality control directions in 25 TLs/SPCs were evaluated to identify deficiencies, incompleteness, restrictions, errors, impracticability, and vagueness. In addition, their congruence with the statements given in the relative European Pharmacopoeia (Ph. Eur. VII ed.) monography and diagnostic reference levels of Directive 97/43/EURATOM was evaluated. Deficiencies in information were scored and classified into five categories: 1, absent or incomplete; 2, restrictive; 3, inconsistent or wrong; 4, impractical; and 5, vague. In the 25 documents analyzed a total of 141 deficiencies were found (corresponding to 40.2% of the total scores assigned), and more frequently they pertained to quality control procedures (70.9%), followed by those related to quantitative composition (14.9%), preparation (8.5%), and particle size (5.7%). Nearly 80% of these deficiencies were classified as type 1 - that is, absent or incomplete information. The indications in TLs and SPCs should provide useful information for maintaining the quality and purity of the radiopharmaceutical preparation and ensure the safety level and effectiveness required by law. However, the instructions are often suboptimal or even erroneous, and consequently there are countless failures or difficulties, which represent an impediment to good laboratory practice. We believe that a 'smart' review of radiopharmaceutical documentation would be beneficial in order to align these indications to the real needs of the operators involved in routine in-house nuclear medicine practice.

    The purpose of this paper is to discuss the pharmaceutical Quality by Design (QbD) and describe how it can be used to ensure pharmaceutical quality. The QbD was described and some of its elements identified. Process parameters and quality attributes were identified for each unit operation during manufacture of solid oral dosage forms. The use of QbD was contrasted with the evaluation of product quality by testing alone. The QbD is a systemic approach to pharmaceutical development. It means designing and developing formulations and manufacturing processes to ensure predefined product quality. Some of the QbD elements include: Defining target product quality profile; Designing product and manufacturing processes; Identifying critical quality attributes, process parameters, and sources of variability; Controlling manufacturing processes to produce consistent quality over time. Using QbD, pharmaceutical quality is assured by understanding and controlling formulation and manufacturing variables. Product testing confirms the product quality. Implementation of QbD will enable transformation of the chemistry, manufacturing, and controls (CMC) review of abbreviated new drug applications (ANDAs) into a science-based pharmaceutical quality assessment.

    Despite the existence of a large community of nurses, specific mechanisms have not been developed yet to consider their needs and the quality of their work life. Moreover, few studies have been conducted to analyze the nature of nursing, nursing places or nurses' quality of work life. In this regard, the present study aimed to assess predictable productivity of nurses working in Kerman University of Medical Sciences' teaching hospitals via the dimensions of Quality of Work Life. The present descriptive-correlational study was conducted to assess predictable productivity of nurses via the dimensions of Quality of Work Life. The study's population consisted of all nurses working in different wards of teaching hospitals associated with Kerman University of Medical Sciences. Out of the whole population, 266 nurses were selected based on the simple random sampling method. To collect data, the questionnaires of 'Quality of Nursing Work Life' and 'Productivity' were used after confirming their reliability (test-retest) and content validity. Finally, the collected data were analyzed through the SPSS software (version 16). Although the quality of work life for nurses was average and their productivity was low but the results showed that quality of life is directly related to nurses' productivity. Quality of life and its dimensions are predictive factors in the in the nurses' productivity. It can conclude that by recognizing the nurses' quality of work life situation, it can realize this group productivity and their values to the efficiency of the health system. For the quality of working life improvement and increasing nurses' productivity more efforts are needed by authorities. The findings can be applied by managers of hospitals and nursing services along with head nurses to enhance the quality of health services and nursing profession in general.

    Gramer, Michael J

    2014-01-01

    The manufacturing of a biologic drug from mammalian cells results in not a single substance, but an array of product isoforms, also known as variants. These isoforms arise due to intracellular or extracellular events as a result of biological or chemical modification. The most common examples related to biomanufacturing include amino acid modifications (glycosylation, isomerization, oxidation, adduct formation, pyroglutamate formation, phosphorylation, sulfation, amidation), amino acid sequence variants (genetic mutations, amino acid misincorporation, N- and C-terminal heterogeneity, clipping), and higher-order structure modifications (misfolding, aggregation, disulfide pairing). Process-related impurities (HCP, DNA, media components, viral particles) are also important quality attributes related to product safety. The observed ranges associated with each quality attribute define the product quality profile. A biologic drug must have a correct and consistent quality profile throughout clinical development and scale-up to commercial production to ensure product safety and efficacy. In general, the upstream process (cell culture) defines the quality of product-related substances, whereas the downstream process (purification) defines the residual level of process- and product-related impurities. The purpose of this chapter is to review the impact of the cell culture process on product quality. Emphasis is placed on studies with industrial significance and where the direct mechanism of product quality impact was determined. Where possible, recommendations for maintaining consistent or improved quality are provided.

  14. Optimal Product Quality of Supply Chain Based on Information Traceability in Fashion and Textiles Industry: An Adverse Logistics Perspective

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available This paper investigates and compares two quality control methods, that is, inspection control and traceability control, to optimize supply chain quality in fashion and textiles industry. The objective is to maximize the supply chain participants’ expected profits and to achieve a Pareto improvement of supply chain product quality. With quality as a controllable variable indicating the level of opportunistic behavior, the return is interpreted as a function of quality: the higher the quality, the lower the return. Taking into account both quality and inventory quantity, we propose and compare the optimal decision-making models for three control methods of supply chain, respectively: decentralized (no control, inspection, and traceability. Further, we use a numerical example to illustrate the relationships among quality, profits, and quality-control cost coefficients (i.e., inspection-related cost and traceability-related cost. We then analyze and discuss the differences in the applications and scopes of the two control methods. On the one hand, given the poor standardization of fashion and textiles industry in the current practice (especially in China market, the cost of sampling inspection is relatively lower as compared to that of the traceability control method. On the other hand, with the improved industrial standardization and technology, traceability control tends to gain increasing advantages in cost and popularity.

    2015-10-01

    Full Text Available In food industry, the cooking is one of the most important processes for the conservation and quality assurance of the final product, especially mortadella. However, this process requires high investment in modern equipment besides having energy and steam expenses.. In this context, the objective of this study was to propose a cooking method of mortadella produced with pork and chicken, by reducing time and increasing temperature inside the baking oven. Evaluations of behavior of water activity, pH and texture of the mortadella were carried out throughout shelf life. From the results, we found that both pork and chicken mortadella that were cooked by the current process and those that passed through the cooking process with reduced time showed no significant differences at the level of 95% confidence for the analyzed characteristics. Therefore, all treatments had similar values and can be considered within the established standards of product quality for both water activity and for pH and texture.

    Full Text Available In the face of water scarcity and the several negative consequences, such as water wastage, flooding, water logging, soil losses and production losses, conserving the finite amount of fresh water is a must. The quality of irrigation water must therefore be ascertained. The chemical quality of three sources of irrigation water from canal and drainage water, namely drainage water, fresh irrigation water from canal, and drainage/irrigation water mixture, were analyzed from Kadawa irrigation Project for year 2013 and 2014 cropping seasons, with the view to evaluating the potential risks associated with their use in irrigation and hence their suitability or otherwise for irrigation purposes. The analysis revealed that the use of drainage water alone for irrigation may result in problems associated with salinity, while a blend of drainage/irrigation water in the ratio of 1:1 is a viable means of water conservation and a good means of crop production.

    Enacted in 1950, Public Law 480 (PL480) dramatically increased the volume of U.S.food aid and the scope of interventions it supports. Billions of dollars have been invested, both to enhance the diets of chronically undernourished people in development settings, and to support nutritional needs during conflicts and natural disasters. Review the institutional processes-from procurement to delivery-that support this programming. We examined the systems that govern and oversee the many components of food aid programming and the extent to which they support a whole-of-government, multi-agency food aid agenda. We conducted consultations with US government employees and contractors, academics, industry representatives, donor agency staff United Nations personnel, and field-level food aid programming technical staff from many countries. A survey of USAID implementing partners conducted among 64 responding offices in 40 countries provided data on the use and effectiveness of enriched, fortified, or blended Title II commodities, the use of new commodities, and related procurement or logistics aspects. Expert panels provided input and feedback throughout the process. We identified potential improvements to overall delivery and cost-effectiveness of USAID programming to better meet the nutrition needs of beneficiaries. Options include changes in product formulation, the range of products provided, and/or the modes of product approval, processing, procurement, and distribution. This research points to several improvements in processes related to food aid: 1) Establish an interagency committee to oversee all government interests in the food aid agenda through an ongoing review process. 2) Enhance processes and quality assurance along the product value chain including the importance of effective interaction with the private sector to incorporate industry best practices and create public-private partnerships to promote product innovations. 3) Strengthen the evidence base for

    Residual internal stresses in PbWO{sub 4} (PWO) scintillating crystals grown by Bridgman method have been systematically studied. Residual stresses induced during growth play an important role in production yield. Cracking probability during mechanical processing as well as stable mechanical properties in finished crystal are closely related to internal stress levels. A regular production of good-quality crystals requires a fast and easy feed-back on growth parameters. Samples from a pre-serial production were analyzed in order to give the producer a quality feed-back for process optimization. By means of photoelasticity, we measured residual stress distribution in several sections along the growth axis and for typical positions in every section. The stress analysis revealed defects occurring during the crystallization process, attributed to dislocations, lattice disorientation and poly-crystallinity. This work had been prompted by the need for quality monitoring of a pre-serial production of PWO for the CMS experiment at CERN's LHC. Mapping stress levels inside the ingot volume and proposing a synthetic parameter to be used as a quality indicator, the resulting analysis should contribute to parameter optimization and improve the growth performance. The proposed method may be useful in conventional crystal production.

    Technological innovation requires the laboratories to ensure that modifications or incorporations of new techniques do not alter the quality of their results. In an ISO 15189 accredited laboratory, flexible scope accreditation facilitates the inclusion of these changes prior to accreditation body evaluation. A strategy to perform the validation of a biochemistry analyzer in an accredited laboratory having a flexible scope is shown. A validation procedure including the evaluation of imprecision and bias of two Dimension Vista analysers 1500 was conducted. Comparability of patient results between one of them and the lately replaced Dimension RxL Max was evaluated. All studies followed the respective Clinical and Laboratory Standards Institute (CLSI) protocols. 30 chemistry assays were studied. Coefficients of variation, percent bias and total error were calculated for all tests and biological variation was considered as acceptance criteria. Quality control material and patient samples were used as test materials. Interchangeability of the results was established by processing forty patients' samples in both devices. 27 of the 30 studied parameters met allowable performance criteria. Sodium, chloride and magnesium did not fulfil acceptance criteria. Evidence of interchangeability of patient results was obtained for all parameters except magnesium, NT-proBNP, cTroponin I and C-reactive protein. A laboratory having a well structured and documented validation procedure can opt to get a flexible scope of accreditation. In addition, performing these activities prior to use on patient samples may evidence technical issues which must be corrected to minimize their impact on patient results.

    This study condenses data acquired during investigations of the virological quality of irrigation water used in production of fresh produce. One hundred and eight samples of irrigation water were collected from five berry fruit farms in Finland (1), the Czech Republic (1), Serbia (2), and Poland (1), and sixty-one samples were collected from three leafy green vegetable farms in Poland, Serbia, and Greece. Samples were analyzed for index viruses of human or animal fecal contamination (human and porcine adenoviruses, and bovine polyoma viruses), and human pathogenic viruses (hepatitis A virus, hepatitis E virus, and noroviruses GI/GII). Both index and pathogenic viruses were found in irrigation water samples from the leafy green vegetables production chain. The data on the presence of index viruses indicated that the highest percentage of fecal contamination was of human origin (28.1 %, 18/64), followed by that of porcine (15.4 %, 6/39) and bovine (5.1 %, 2/39) origins. Hepatitis E virus (5 %, 1/20) and noroviruses GII (14.3 %, 4/28) were also detected. Samples from berry fruit production were also positive for both index and pathogenic viruses. The highest percentage of fecal contamination was of human origin (8.3 %, 9/108), followed by that of porcine, 4.5 % (4/89) and bovine, 1.1 % (1/89) origins. Norovirus GII (3.6 %, 2/56) was also detected. These data demonstrate that irrigation water used in primary production is an important vehicle of viral contamination for fresh produce, and thus is a critical control point which should be integrated into food safety management systems for viruses. The recommendations of Codex Alimentarius, as well as regulations on the use of water of appropriate quality for irrigation purposes, should be followed.

    A chemistry point-of-care analyzer would be useful for evaluating injured wildlife, particularly White rhinoceros (Ceratotherium simum) that survive poaching attempts. The IDEXX VetTest could be suitable, but species-specific validation, development of a statistical quality control (QC) strategy, and evaluation under field conditions are necessary. The objectives were to (1) validate the VetTest for the White rhinoceros, (2) perform QC validation on the VetTest and generate a statistical QC strategy, and (3) apply this QC strategy to monitor performance under typical field conditions. Differences between White rhinoceros heparin plasma and serum, short-term imprecision, and reportable range using rhinoceros plasma and long-term imprecision using commercial quality control material (QCM) were assessed against prescribed total allowable error (TE a ) for up to 15 analytes. Quality control validation was performed using data from the long-term imprecision study and TE a . A QC strategy using QCM was developed and used to monitor performance under field conditions. Imprecision was acceptable for all analytes except for ALP, ALT, and AST at low activities. The reportable range for AST and LDH differed from the manufacturer's specifications. Eleven analytes were suitable for statistical QC using the 1 3s rule, 3 using the 2 s rule; ALP was not suitable. In the field, observed error was 3.0 for 12 analytes. The VetTest is suitable for use in the White rhinoceros. Statistical QC is possible for most analytes and useful for evaluation of field performance. © 2017 American Society for Veterinary Clinical Pathology.

    Kroes, Burt H

    2014-12-02

    In the European Union a complex regulatory framework is in place for the regulation of (traditional) herbal medicinal products. It is based on the principle that a marketing authorisation granted by the competent authorities is required for placing medicinal products on the market. The requirements and procedures for acquiring such a marketing authorisation are laid down in regulations, directives and scientific guidelines. This paper gives an overview of the quality requirements for (traditional) herbal medicinal products that are contained in European pharmaceutical legislation. Pharmaceutical quality of medicinal product is the basis for ensuring safe and effective medicines. The basic principles governing the assurance of the quality of medicinal products in the European Union are primarily defined in the amended Directive 2001/83/EC and Directive 2003/63/EC. Quality requirements of herbal medicinal products are also laid down in scientific guidelines. Scientific guidelines provide a basis for practical harmonisation of how the competent authorities of EU Member States interpret and apply the detailed requirements for the demonstration of quality laid down in regulations and directives. Detailed quality requirements for herbal medicinal products on the European market are contained in European Union (EU) pharmaceutical legislation. They include a system of manufacturing authorisations which ensures that all herbal medicinal products on the European market are manufactured/imported only by authorised manufacturers, whose activities are regularly inspected by the competent authorities. Additionally, as starting materials only active substances are allowed which have been manufactured in accordance with the GMP for starting materials as adopted by the Community. The European regulatory framework encompasses specific requirements for herbal medicinal products. These requirements are independent from the legal status. Thus, the same quality standards equally apply

    The findings are reported of the Jet Propulsion Laboratory (JPL)/Software Product Assurance (SPA) Metrics Study, conducted as part of a larger JPL effort to improve software quality and productivity. Until recently, no comprehensive data had been assembled on how JPL manages and develops software-intensive systems. The first objective was to collect data on software development from as many projects and for as many years as possible. Results from five projects are discussed. These results reflect 15 years of JPL software development, representing over 100 data points (systems and subsystems), over a third of a billion dollars, over four million lines of code and 28,000 person months. Analysis of this data provides a benchmark for gauging the effectiveness of past, present and future software development work. In addition, the study is meant to encourage projects to record existing metrics data and to gather future data. The SPA long term goal is to integrate the collection of historical data and ongoing project data with future project estimations.

    Spruce, J.; Hargrove, W. W.; Gasser, J.; Smoot, J.; Kuper, P.

    2014-12-01

    This presentation discusses MODIS NDVI change detection methods and products used in the ForWarn Early Warning System (EWS) for near real time (NRT) recognition and tracking of regionally evident forest disturbances throughout the conterminous US (CONUS). This EWS has provided NRT forest change products to the forest health protection community since 2010, using temporally processed MODIS Aqua and Terra NDVI time series data to currently compute and post 6 different forest change products for CONUS every 8 days. Multiple change products are required to improve detectability and to more fully assess the nature of apparent disturbances. Each type of forest change product reports per pixel percent change in NDVI for a given 24 day interval, comparing current versus a given historical baseline NDVI. EMODIS 7 day expedited and MODIS MOD13 data are used to obtain current and historical NDVIs, respectively. Historical NDVI data is processed with the Time Series Product Tool (TSPT) and the Phenological Parameters Estimation Tool (PPET) software. While each change product employs maximum value compositing (MVC) of NDVI, the design of specific products primarily differs in terms of the historical baseline. The three main change products use either 1, 3, or all previous years of MVC NDVI as a baseline. Another product uses an Adaptive Length Compositing (ALC) version of MVC to derive an alternative current NDVI that is the freshest quality NDVI as opposed to merely the MVC NDVI across a 24 day time frame. The ALC approach can improve detection speed by 8 to 16 days. ForWarn also includes 2 change products that improve detectability of forest disturbances in lieu of climatic fluctuations, especially in the spring and fall. One compares current MVC NDVI to the zonal maximum under the curve NDVI per pheno-region cluster class, considering all previous years in the MODIS record. The other compares current maximum NDVI to the mean of maximum NDVI for all previous MODIS years. The

    2017-09-01

    The Precision Reactor Oscillation and Spectrum Experiment (PROSPECT) is an electron antineutrino (νe) detector intended to make a precision measurement of the 235U neutrino spectrum and to search for the possible existence of sterile neutrinos with a mass splitting of Δm2 on the order of 1 eV2 . As a short baseline detector, PROSPECT will be located less than 10 meters from the High Flux Isotope Reactor at Oak Ridge National Laboratory. As PROSPECT intends to search for baseline-dependent oscillations, physical segmentation is needed to better measure the interaction position. PROSPECT will therefore be a segmented detector in two dimensions, thereby improving position measurements. PROSPECT will be segmented into 154 (11×14) 1.2-meter long rectangular tubes, using optical separators. Each separator will consist of a carbon fiber core, laminated with optical reflector (to increase light collection) and Teflon (to ensure compatibility with the scintillator). These optical separators will be held in place via strings of 3D printed PLA rods called `pinwheels.' This poster discusses the fabrication and quality assurance (QA) procedures used in the production of both the PROSPECT optical separators and pinwheels. For the PROSPECT collaboration.

  16. The Effects of Agricultural Raw Product Exports on Environment Quality

    2016-10-01

    Full Text Available Introduction: The relationship between openness, trade and environmental damaging are the most important problems in the early 1990s. Some scientists assume the environmental quality is a normal good and increasing income increases demand for environmentally safe products. Therefore, Firms will be encouraging the using of safer and less polluting procedure. On the other hand other scientists assume international trade grows the environmental degradation through environmentally polluting industries and expand economics scales in developing countries. While environmental standards are low in these countries, the expansion of trade will lead to more pollution. Some experimental studies have confirmed a negative relationship between trade and environment. The effect of import and export of trade is not considered as important components of trade, despite very consideration of the relationship between openness, trade and environmental by researchers while in general part trade may have different effect on environmental. Materials and Methods: The base model is used to study the relationship between economic growth and environmental indexes and trade. Grossman and Krueger (1991 and Shafik and Bandvpady (1992 used the trade intensity variable, obtained from the ratio of exports plus imports divided by GDP as the World Trade openness of an economy measure. Grossman and Krueger (1991, the first person who developed environmental Kuznets curve (EKC used multiple versions of the model.

    Global competition in the automotive industry has encouraged companies to implement quality management practices in all managerial aspects to ensure customer satisfaction in products and reduce costs. Therefore, guaranteeing only product quality is insufficient without considering product sustainability, which involves economic, environment, and social elements.

    The level of quality that a product offers to consumers is a fundamental aspect of competition in many markets. Consumers’ confidence in the safety and quality of foods they buy and consume is a significant support to the economic development of production organizations of this type, and therefore the overall economic development. Consumer concerns about food safety as well as the globalization of food production have also led to the existence of a global internationally linked food production and distribution system. The necessity demanded by the consumer population to provide safe food with consistent quality at an attractive price imposes a choice of an appropriate quality assurance model in accordance with the specific properties of the product and the production processes. Modern trends, especially for the last ten years in quality assurance within specific production, such as the food industry, have marked the trend of hyperproduction and a number of production and safety standards, as well as a change of approach in the certification process of organizations according to one or more standards. This can be an additional source of costs for organizations, and can burden the food business operator`s budget in order to ensure their consistent application and maintenance. Quality assurance (QA) standards are considered to be a proven mechanism for delivering quality of product.

    Everyday life can no longer be imagined without fragrances and scented products. For the consumer, countless products exists which are solely or partly intended to give off a certain scent in sufficient concentrations to odorize a complete room. Sprays, diffusers and evaporators, scented candles and automatic devices for the distribution of fragrance liquids are typical examples of such products. If the consumer uses such products, his consent to the release of certain chemicals in his home can be implied, however, he may not know what kind of fragrance substances and solvents will be present in which concentrations. In this study, we determined the volatile emissions of a number of fragrance products in detail. Measurements were carried out under controlled conditions in test chambers. The products were tested in a passive (unused) and an active state, wherever applicable. Following a defined test protocol, the release of volatile organic compounds, ultrafine particles and NOx was monitored for each product. The potential for forming secondary organic aerosols under the influence of ozone was studied, and for a selection of products the long-term emission behavior was assessed. A remarkable variety of fragrance substances was found and more than 100 relevant compounds were identified and quantified. While it is the intended function of such products to release fragrance substances, also considerable amounts of non-odorous solvents and by-products were found to be released from several air fresheners. Emissions rates exceeding 2 mg/(unit*h) were measured for the five most common solvents.

  1. INSURANCE OF KNITTED PRODUCTS QUALITY THROUGH THE ANALYSIS AND EVALUATION OF NON-QUALITY DURING ASSEMBLY BY STITCHING

    Full Text Available In a knitting factory, any activity oriented toward evaluation, maintenance or improvement of products quality level is based on measuring and examining the product quality characteristics, in order to establish conformity to the quality specifications and/or naming the non-quality characteristics, thus noticing defects or fabrication deficiencies. The quality of the stitching operation has a particular influence on the finite product quality and is determined on side by the quality of knitted pieces, and on the other by insuring the correlation between the technological parameters of the stitching operation and the physico-mechanical characteristics of the knittings that are to be assembled through stitching. Although the product execution processes comprise of manufacturing the elements and distinct subassemblies and their ulterior assembly, they present various difference dictated by the constructive particularities of the machine, as well as fabric characteristics. Because of the multiple interactions between the material, yarn and working parts of the sawing machine, inadequacies in the technological discipline can result in negative effects on both the knitted and stitching thread as well as the machine. A part of these can be fixed by extra time consuming tasks (yarn breaks, stitching ruffling etc., while other defects appear during the usage of the product cheapening it (stitch tearing by perforating the knitted on the stitching line, pilling effect, dimensional instability etc.. This paper systematically presents, the main defects that may occur during the stitching operation of the products made out of circular knitted, as well as the causes that generate them along with preventive or corrective actions.

    The water quality of receiving streams and waterbodies in urban watersheds are increasingly polluted from stormwater runoff. The implementation of Green Infrastructure (GI), which includes Low Impact Developments (LIDs) and Best Management Practices (BMPs), within a watershed aim to mitigate the effects of urbanization by reducing pollutant loads, runoff volume, and storm peak flow. Stormwater modeling is generally used to assess the impact of GIs implemented within a watershed. These modeling tools are useful for determining the optimal suite of GIs to maximize pollutant load reduction and minimize cost. However, stormwater management for most resource managers and communities also includes the implementation of grey and hybrid stormwater infrastructure. An integrated decision support tool, called i-DST, that allows for the optimization and comprehensive life-cycle cost assessment of grey, green, and hybrid stormwater infrastructure, is currently being developed. The i-DST tool will evaluate optimal stormwater runoff management by taking into account the diverse economic, environmental, and societal needs associated with watersheds across the United States. Three watersheds from southern California will act as a test site and assist in the development and initial application of the i-DST tool. The Ballona Creek, Dominguez Channel, and Los Angeles River Watersheds are located in highly urbanized Los Angeles County. The water quality of the river channels flowing through each are impaired by heavy metals, including copper, lead, and zinc. However, despite being adjacent to one another within the same county, modeling results, using EPA System for Urban Stormwater Treatment and Analysis INtegration (SUSTAIN), found that the optimal path to compliance in each watershed differs significantly. The differences include varied costs, suites of BMPs, and ancillary benefits. This research analyzes how the economic, physical, and hydrological differences between the three

    Introduction Technological innovation requires the laboratories to ensure that modifications or incorporations of new techniques do not alter the quality of their results. In an ISO 15189 accredited laboratory, flexible scope accreditation facilitates the inclusion of these changes prior to accreditation body evaluation. A strategy to perform the validation of a biochemistry analyzer in an accredited laboratory having a flexible scope is shown. Materials and methods: A validation procedure including the evaluation of imprecision and bias of two Dimension Vista analysers 1500 was conducted. Comparability of patient results between one of them and the lately replaced Dimension RxL Max was evaluated. All studies followed the respective Clinical and Laboratory Standards Institute (CLSI) protocols. 30 chemistry assays were studied. Coefficients of variation, percent bias and total error were calculated for all tests and biological variation was considered as acceptance criteria. Quality control material and patient samples were used as test materials. Interchangeability of the results was established by processing forty patients’ samples in both devices. Results: 27 of the 30 studied parameters met allowable performance criteria. Sodium, chloride and magnesium did not fulfil acceptance criteria. Evidence of interchangeability of patient results was obtained for all parameters except magnesium, NT-proBNP, cTroponin I and C-reactive protein. Conclusions: A laboratory having a well structured and documented validation procedure can opt to get a flexible scope of accreditation. In addition, performing these activities prior to use on patient samples may evidence technical issues which must be corrected to minimize their impact on patient results. PMID:23457769

    Since the product recall problem is recently observed, realizing design and production activities that can prevent occurrences of a product failure has been becoming a serious issue. This paper proposes "the Synthetic design approach of a product and a production process which enables to reduce occurrences of a product failure from the initial stage of a product development." In order to realize this proposed concept as a specific system, the integrated model of the failure information in the design and production is introduced. This paper shows some examples of design and production for a circuit breaker and an automobile with considering a design error and a production failure using developed prototype system.

  15. Flexible optical metrology strategies for the control and quality assurance of small series production

    The demand for achieving smaller and more flexible production series with a considerable diversity of products complicates the control of the manufacturing tasks, leading to big challenges for the quality assurance systems. The quality assurance strategy that is nowadays used for mass production is unable to cope with the inspection flexibility needed among automated small series production, because the measuring strategy is totally dependent on the fixed features of the few manufactured object variants and on process parameters that can be controlled/compensated during production time. The major challenge faced by a quality assurance system applied to small series production facilities is to guarantee the needed quality level already at the first run, and therefore, the quality assurance system has to adapt itself constantly to the new manufacturing conditions. The small series production culture requires a change of paradigms, because its strategies are totally different from mass production. This work discusses the tight inspection requirements of small series production and presents flexible metrology strategies based on optical sensor data fusion techniques, agent-based systems as well as cognitive and self-optimised systems for assuring the needed quality level of flexible small series. Examples of application scenarios are provided among the automated assembly of solid state lasers and the flexible inspection of automotive headlights.

    Milk and its products as a kind of ideal comprehensive nutritional food, has becoming an indispensable part of people's daily, life. But at the same time, the quality of dairy products has been also increasingly concerned by consumers. Real-time, rapid and accurate detection of milk and its products in terms of component, adulterants, residues and preservatives is the primary condition for improving the dairy products quality and controlling the production process. Quality predication of milk and its products was often completed by laboratory analysis in the past, which was complicated and time-consuming and could not satisfy the needs for evaluating the milk products quality and monitoring the production proceeding effectively. How to predict the quality of milk and its products quickly and accurately is a practical problem that needs to be resolved. Near-infrared spectroscopy (NIRS) is a rapid, convenient, highly efficient, non-destructive and low-cost analytical technique, which has been widely used in various fields for quantitative and qualitative analysis. As a new analysis technique, NIRS has great potential of application to milk and its products detection, owning to its quick, concise and non--destructive characteristics. The main nutrient components were the major index of milk and its products quality evaluation. Determining the main nutrient components of milk and its products rapidly can provide sound basis for evaluating the products quality. At the same time, adulterants, residues and preservatives were also distinct fingerprint characteristics in the NIR spectra just like the main nutrient components. So this new approaches could also be used in quality distinguishing and on-line detection of milk and its products. Many researches have also concluded that NIRS technology has good stability and high prediction ability on dairy products analysis, exhibites well correlation with the result by labor analysis method. In the present paper, the principles

    This paper presents an overview of Project ATLANTA (ATlanta Land use ANalysis: Temperature and Air-quality) which is an investigation that seeks to observe, measure, model, and analyze how the rapid growth of the Atlanta, Georgia metropolitan area since the early 1970's has impacted the region's climate and air quality. The primary objectives for this research effort are: (1) To investigate and model the relationships between land cover change in the Atlanta metropolitan, and the development of the urban heat island phenomenon through time; (2) To investigate and model the temporal relationships between Atlanta urban growth and land cover change on air quality; and (3) To model the overall effects of urban development on surface energy budget characteristics across the Atlanta urban landscape through time. Our key goal is to derive a better scientific understanding of how land cover changes associated with urbanization in the Atlanta area, principally in transforming forest lands to urban land covers through time, has, and will, effect local and regional climate, surface energy flux, and air quality characteristics. Allied with this goal is the prospect that the results from this research can be applied by urban planners, environmental managers and other decision-makers, for determining how urbanization has impacted the climate and overall environment of the Atlanta area. Multiscaled remote sensing data, particularly high resolution thermal infrared data, are integral to this study for the analysis of thermal energy fluxes across the Atlanta urban landscape.

    Probiotics are widely used in the food industry and medicine fields in China, but few studies have been conducted to evaluate the actual microbial amounts and species in probiotic products, which may conflict with the labels and mislead consumers to choose inappropriate foods or medicines. Twenty commercial dairy products and eight commercial 'healthcare' samples were collected from markets in China and tested using culture-dependent and culture-independent methods. The results suggested that the total bacterial counts of most commercial products met the minimum quantitative requirement of the Chinese national standard (6.00 log colony-forming units g(-1) ). However, the bacterial counts of specific species were inconsistent with the labelling. In parallel, denaturing gradient gel electrophoresis analysis indicated that some probiotic-containing products were wrongly labelled; no Bifidobacterium species were detected in the products claiming to contain bifidobacteria, and the probiotic characteristics (antimicrobial activity, acid resistance and bile resistance) of some isolates had degraded. Moreover, some contaminating bacteria, e.g. Enterobacter sp., Klebsiella sp. and Serratia sp., were also detected in these products. The combination of culture-dependent and culture-independent methods was proven to quickly and conveniently detect the microbial diversity in probiotic products, and more effort is required to regulate the probiotic market in China. © 2013 Society of Chemical Industry.

    Rare earth system Gadolinium (Gd), in either pure form or oxide form, is highly stable against environmental attack. It has immense potential as a contrast agent in magnetic resonance imaging (MRI) devices. Being mechanically and thermally stable it is always difficult to obtain Gd 2 O 3 nanopowders directly from its bulk counterpart using conventional top-down approach. Recently, we have reported production of Gd 2 O 3 nanopowders by first converting bulk Gd 2 O 3 into a nitrate compound and subsequently reduced into a hydroxide product and finally to the oxide product (nanopowder form)
