  1. Analyzing the thermodynamic behavior of ferroalloys in quality control of structural steel products

    International Nuclear Information System (INIS)

    Ferroalloys are the tonnage metals of the steel industry; serve as alloying elements for the production of steel of various grades to improve the mechanical and physical properties to control the grain size and corrosion resistance of the steel. In this paper we have discussed on Fe Mn and Fe Si alloys used for steel products of various structural shapes like. beams, angles, tees, zees and channels. We also discuss on quality of structural steel products and energy consumption. In our work we have studied the thermodynamic behavior of ferroalloys by using DSC/TGA, which helped us to determine the actual temperature for addition of alloying elements in furnace to save energy and improve the quality of structural steel products. This research proved that in future we can reduce energy consumption and will improve the quality of structural steel products according to our requirements which can fulfill today's market demand.

    To analyze China's fluctuating situation of the factor input and aggregative productivity is not only the main method to seek the source of the economic growth but also the main way to weigh the level of economic growth quality. As to economic growth of a country, the improvement of the productivity is extremely important. The growth of the output can be realized through two kinds of ways: increasing the quantity of factor input of or improving the efficiency of the input and output. Therefore, the level of economic growth quality does not mainly depend on the amount of invested factor, but the importance of improving the productivity since resources are rare.The relative improvement of efficiency in use of the invested factor marks the economic growing quality. So, in order to understand the economic growth quality of China to some extent, it must analyze Chinese factor input and aggregative productivity. This is the main topic that this text will be probed into.

    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.

    Full Text Available Power quality is a set of boundaries that allows electrical systems to function in their intended manner without significant loss of performance or life. The term is used to describe electric power that drives an electrical load and the load's ability to function properly with that electric power. Without the proper quality of the power, an electrical device may malfunction, fail prematurely or not operate at all. There are many reasons why the electric power can be of poor quality and many more causes of such poor quality power. Power quality of power systems, which affects all connected electrical and electronic equipment, is a measure of deviations in voltages, currents, frequency, temperatures, winding forces and torques of particular supply systems and their components. In recent years, a considerable increase in nonlinear loads has been experienced; in particular distributed loads, such as computers, monitors and lighting, and distributed sources. The aim of this paper is to display a way of monitoring and analyzing features of electrical power quality system. As a monitoring example is taken output from power transformer rated at 320 kVA, part of distribution grid of Durres City in Albania.

  15. New techniques for analyzing relationships between energy and water quality

    International Nuclear Information System (INIS)

    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

    Soler, M. E.; Kornus, W.; Magariños, A.; Pla, M.

    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. Different variables such as flight altitude, side and forward overlap and ground control point measurements and location have been considered for the evaluation of aerial triangulation and

  18. Quality control of radioisotopic products

    International Nuclear Information System (INIS)

    Radiopharmaceutical quality control is a very comprehensive and responsible activity since it concerns products being used for the health care of patients. Quality control is practised by an analytical specialist in close cooperation with pharmacists who are responsible for routine quality assurance. There is also a good understanding with the production group to ensure high-quality products. Quality control also relies on the research and development group to investigate problems. Finally there is feedback from the user since he is also responsible for quality control in a limited way. The scope of quality control is comprehensive, e.g. physical inspection and chemical control of all inactive starting material including supervision of the various stages of production. The quality control of radioactive material includes nuclidic analysis, verification of radiochemical purity as well as regular stability checks. Biological controls comprise sterility tests both on final products and production environment; testing for toxicity, pyrogens and LD50 values. To test product efficacy it is imperative to rely on biodistribution. Rabbits are used for quality control screening in a qualitative static mode and the dissection of mice organs is carried out for time-consuming quantitative analyses. Since radiopharmaceuticals are being used in a dynamic mode by nuclear medicine, their quality control tests on animals should, for proper evaluation, be carried out by means of comparative studies with imported products and by using a high-resolution camera with computer facilities. The Group for Quality Control and Assurance is responsible for an extensive documentation system which ensures both good manufacturing practice and effective analytical tests. Through quality control the specialist is constantly striving for improvement to ensure a good product for the benefit of the patient

    2011-07-01

    Full Text Available In order to produce and develop a software system, it is necessary to have a method of choosing a suitable software architecture which satisfies the required quality attributes and maintains a trade-off between sometimes conflicting ones. Each software architecture includes a set of design decisions for each of which there are various alternatives, satisfying the quality attributes differently. At the same time various stakeholders with various quality goals participate in decision-making. In this paper a numerical method is proposed that based on the quality attributes selects the suitable software architecture for a certain software. In this method, for each design decision, different alternatives are compared in view of a certain quality attribute, and the other way around. Multi-criteria decision-making methods are used and, at the same time, time and cost constraints are considered in decision-making, too. The proposed method applies the stakeholders' opinions in decision-making according to the degree of their importance and helps the architect to select the best software architecture with more certainty.

    2011-02-01

    Full Text Available Fault proneness data available in the early software life cycle from previous releases or similar kind of projects will aid in improving software quality estimations. Various techniques have been proposed in the literature which includes statistical method, machine learning methods, neural network techniques and clustering techniques for the prediction of faulty and non faulty modules in the project. In this study, Hierarchical clustering algorithm is being trained and tested with lifecycle data collected from NASA projects namely, CM1, PC1 and JM1 as predictive models. These predictive models contain requirement metrics and static code metrics. We have combined requirement metric model with static code metric model to get fusion metric model. Further we have investigated that which of the three prediction models is found to be the best prediction model on the basis of fault detection. The basic hypothesis of software quality estimation is that automatic quality prediction models enable verificationexperts to concentrate their attention and resources at problem areas of the system under development. The proposed approach has been implemented in MATLAB 7.4. The results show that when all the prediction techniques are evaluated, the best prediction model is found to be the fusion metric model. This proposed model is also compared with other quality models available in the literature and is found to be efficient for predicting faulty modules.

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.

  9. A bio-economic approach to analyze the role of alternative seeding-harvesting schedules, water quality, stocking density and duration of cultivation in semi-intensive production of shrimp in Mexico

    Directory of Open Access Journals (Sweden)

    Margarita Estrada-Pérez

    2015-07-01

    Full Text Available We used a bio-economic model to analyze the role that alternative seeding-harvesting schedules, temperature, dissolved oxygen, stocking density, and duration of cultivation play in the economic performance of semi-intensive shrimp cultivation in Mexico. The highest production was predicted for the May-August schedule (1130-2300 kg ha-1, while the lowest yields were obtained for the March-June schedule (949-1300 kg ha-1. The highest net revenues were projected for the August-November schedule (US$354-1444 ha-1, while the lowest was projected for the May-August schedule (US$330-923 ha-1. The highest annual net revenues were predicted for the combination of the March-June and August-November schedules (US$1432-2562 ha-1. Sensitivity analysis indicated temperature and dissolved oxygen were the most important factors determining net revenues in March-June schedule. For the May-August and August-November schedules, stocking density was the most important factor. Duration of cultivation was the least sensitive variable. Break-even production analysis confirmed that the combination of the March-June and August-November schedules were more efficient from an economic perspective. We recommend test some ponds with higher stocking density in the March-June and August-November schedules, and in the latter case, seeding in June or July rather than August.

    2003-10-01

    This paper describes a method to control output product quality (product variability) by applying engineering or automatic process control (APC) and statistical process control (SPC) techniques. APC techniques have been used to control process variables such as feed rate, temperature, pressure, viscosity, and to product quality variables as well. SPC techniques have also been applied to control product quality. APC and SPC techniques overlap at the interface of the two process control methodologies. It is possible to produce material of desired quality by having an acceptable level of variation in the measured output characteristics. APC aims to maintain certain key process variables as near their set points for as much of the time as possible. There are situations in process control where some form of feedback control is necessary and yet where stability cannot be easily attained in the feedback control loop. Disturbance (noise) afflicts a process, which together with issues of dynamics and dead time (time delay) compounds the process control problem. The process control practitioner faces a challenge while tackling issues of process delay (dead time) and dynamics (inertia). Process control of product variability (control error standard deviation) is possible by developing and simulating a feedback control algorithm for dead-time processes. It is quite common to encounter problems connected with feedback (closed-loop) control stability, controller limitations, and dead-time compensation to obtain minimum variance (mean square error) control at the output. Details of a method to control the quality of a product at output by applying statistical process monitoring and feedback control adjustment are presented in this paper. The focus of this paper is on the issues of process delay ("dead time") and dynamics ("inertia") at the interface between SPC and APC to control output product quality. PMID:14582886

    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

    We develop a model of product differentiation in which firms strategically compete in product quality and advertising intensity. Consumers face a trade-off between higher quality goods and price. Increased competition may lead to higher or lower quality products. Consumers always benefit from more competition as a reduction in price offsets reduced quality.

  20. Quality Products - The CANDU Approach

    International Nuclear Information System (INIS)

    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. The close collaboration between Atomic Energy of Canada Limited, Canadian industry and the

    Full Text Available The purpose of this study is to investigate the product quality control performance of vegetable cooperatives in China, using Heilongjiang province as a case. This study applies fuzzy integral theory to develop a comprehensive evaluation model and analyzes the product quality control performance of the vegetable cooperatives. The results show that the performance of vegetable cooperatives in the production process is the highest. That is, vegetable cooperatives have important effect on the performance of product quality control mainly in the production process. Through the large-scale operation and the implementation of standardized production, vegetable cooperatives can effectively transform the decentralized production into the unified production. To exert the role of vegetable cooperatives in the product quality control, the incentive systems and the financial support policies should be improved and actively implement the brand strategy.

    2011-01-01

    This article analyzes the effect of competition on a supermarket firm's incentive to provide product quality. In the supermarket industry, product availability is an important measure of quality. Using U.S. Consumer Price Index microdata to track inventory shortfalls, I find that stores facing more intense competition have fewer shortfalls. Competition from Walmart—the most significant shock to industry market structure in half a century—decreased shortfalls among large chains by about a third. The risk that customers will switch stores appears to provide competitors with a strong incentive to invest in product quality. PMID:22148133

    2013-04-01

    Full Text Available Software quality cannot be improved simply by following industry standards which require adaptive/upgrading of standards or models very frequently. Quality Assurance (QA at the design phase, based on typical design artifacts, reduces the efforts to fix the vulnerabilities which affect the cost of product. Different design metrics are available, based on their results design artifacts can be modified. Modifying or making changes in artifacts is not an easy task as these artifacts are designed by rigorous study of requirements. The purpose of this research work is to automatically find out software artifacts for the system from natural language requirement specification as forward engineering and from source code as reengineering, to generate formal models specification in exportable form that can be used by UML compliment tool to visually represent the model of system. This research work also assess these design models artifacts for quality assurance and suggest alternate designs options based on primary constraints given in requirement specification. To analyze, extract and transform the hidden facts in natural language to some formal model has many challenges and obstacles. To overcome some of these obstacles in software analysis there should be some mean or a technique which aims to generate software artifacts to build the formal models such as UML class diagrams. Initially, the proposed technique converts the NL business requirements into a formal intermediate representation to increase the accuracy of the generated artifacts and models. Next, it focuses on identifying the various software artifacts to generate the analysis phase models. Finally it provides output in the format understood by model visualizing tool. The re-engineering process to find out design level artifacts and model information about the previous version of software system from available source code with easy layout is a very difficult task.

    Goswami, Anjan; Chung, Sung H.; Chittar, Naren; Islam, Atiq

    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 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.

    Kwon, Yongjin; Tseng, Bill; Chiou, Richard

    2007-09-01

    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.

    2009-12-01

    Presenting science fair projects gave students an opportunity to complete a performance assessment that comprised a meaningful task focused on process and subject to standards-based assessment. Students presented science inquiry and engineering design projects to judges at a regional science fair. The judges used the domains of the Potter Rubrics to assess the students' work and assigned a Quality score to each project. Using multiple regression, this study found that the mean scores on the Methods and Analysis domains predicted the mean Quality scores. Analyzing the technical quality of the Potter Rubrics addressed some of the measurement and generalizability concerns about performance assessments. Recommendations for future research and implications for practice were examined.

  3. Unit Values in International Trade and Product Quality

    Directory of Open Access Journals (Sweden)

    2015-06-01

    Full Text Available Is the unit value of traded goods representative of quality? To answer this question, we analyze unit value with respect to exporter country’s capacity to export, which is determined by its production cost, tariff, and distance. The change in a country’s export unit value is decomposed into the components associated with pure term-of-trade effect, quality effect, distance effect, and production cost effect. Our empirical results confirm that tariff, distance, and wages all significantly affect the unit values. Furthermore, by comparing CIF and FOB unit values, we show that quality is an important contributor on driving up the unit values: exporters increase unit price to distant trading partners through quality upgrading. This “Washington apple effect” is much larger than the pure distance effect or production cost increase.

  5. Analyzing textual databases using data mining to enable fast product development processes

    International Nuclear Information System (INIS)

    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

  9. Soil quality: key for sustainable production

    Directory of Open Access Journals (Sweden)

    Stefano Mocali

    2011-02-01

    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.

  11. Fermented products with probiotic qualities.

    Kalantzopoulos, G

    1997-01-01

    For several centuries, fermented products derived from plant or animal materials have been an acceptable and essential part of the diet in most parts of the world. Health benefits have also often been associated with them. Probiotics can be defined as fermented food containing specific live microorganisms or a live microbial food or feed supplement, which beneficially effects the human or the host animal by improving its intestinal microbial balance. Nearly all probiotics currently on the market contain Lactobacilli, Streptococci, Enterococci or Bifidobacteria. In contrast to Japan, where freeze-dried microorganisms are consumed by a substantial part of the human population, in Europe, probiotic action towards humans are only claimed for certain fermented dairy products (e.g. yoghurts). Those species that have been extensively studied so far, with several experimental trials on man, are the two yoghurt bacteria Streptocaccus thermophilus and Lactobacillus bulgaricus, L. casei and Bifidobacteria. L. acidophilus has also received important scientific interest, however, only a few human studies have been carried out. From the technological point of view a good probiotic should be stable and viable for long periods under storage, should be able to survive the low pH levels of the stomach, be able to colonise the epithelium of the gastro-intestinal tract of the host, should not be pathogenic and, last but not least, must be capable of exerting a growth promoting effect or a resistance to infectious diseases. The beneficial effects of probiotics are mainly contributed to a direct antagonistic effect against specific groups of microorganisms (Enteropathogenes), by an effect on the metabolism in the gut or by a stimulation of systemic or mucosal immunity. We will present major proven health benefits of milks fermented with those bacterial species and discuss, where possible, the impact of the specific selection and utilisation of particular strains.

    Full Text Available World milk production has a great economical effect being in the function of human food production and nutrition. Milk is obtained from cows, buffalos, sheeps, goats, camels and donkey with cow's milk production dominating. The world milk production in 2000 was 568.480 thousands of tons of all types of milk of which 484.895 thousands tons are cow's milk with a total of 85.30 % of the world milk production. Buffalo's milk production is on the second place with 61.913 thousands of tonnes (10.89 % production capacity. On the three continents (Europe, North America and Asia 81.82 % of total cow's milk production is located. Developed countries produce 50 % of total milk production, while higher milk production is forecast for the developing countries. The EU countries participate with 23.72 % in the world milk production and with 55.60 % on the European area. High annual lactation production, under selected cow's milk production, of above 6000 kg is located in developed countries, where annual participation of Israel accounts for over 10000 kg of milk per cow. Commercial milk production of genetics cattle accounts from 80 % to 85 %. Milk quality, with regard to milk fat and proteincontent, in developed countries is above an average value. With the annual milk production of 7000 kg of cow's milk, up to 294 kg of milk fat and 238 kg of protein are produced. Due to milk characteristics as agro-food product, milk and dairy products manufacture and transportation are in details regulated with existing quality standards. 95 % of the EU milk producers fulfil international hygienic rules on milk safety standards (somatic cells, microorganisms. With regard to long term development, until 2030, changes on herd management (outdoor and indoor exposure, between continents, will occur. In 2030, the world milk production is forecast to increase by 64%, with cow's milk production of 765.9 million tonnes.

    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.

In this paper it was worked out and introduced the way of marking the documents with regard to the quality costs.Design/methodology/approach: In the frames of own research it has been analysed the quality costs in the production process from the documents marked using the worked out way of marking.Findings: On the basis of the own research it can be stated, that the majority of the elements of the quality costs can be counted on the base of generic costs arrangement through the foundation of the suitable accounts and the suitable marking of the source documents.Research limitations/implications: In management practice, enterprises have to choose the way of the identification, control and analysis of the quality costs answering their needs, using among others proposed in this paper the way of marking the documents.Practical implications: The suitable marking of the documents gives the possibility of recording the quality costs of given production process, and not only for the whole enterprise. But each enterprise should take into account the appropriate way of marking the documents to collect all the elements of the quality costs.Originality/value: The extremely important problem from the point of view of the quality costs account and analysis is defining the places of cost formation in such way, that the costs would not be recorded according to the places of appearing but the places of formation. Thanks to these research it is possible to get the information about the quality costs of each process and this paper can be a simple rule how to collect the quality costs from each process.

  20. A rapid and automated low resolution NMR method to analyze oil quality in intact oilseeds

    International Nuclear Information System (INIS)

    Oilseeds with modified fatty acid profiles have been the genetic alternative for high quality vegetable oil for food and biodiesel applications. They can provide stable, functional oils for the food industry, without the hydrogenation process that produces trans-fatty acid, which has been linked to cardiovascular disease. High yield and high quality oilseeds are also necessary for the success of biodiesel programs, as polyunsatured or saturated fatty acid oil produces biofuel with undesirable properties. In this paper, a rapid and automated low resolution NMR method to select intact oilseeds with a modified fatty acid profile is introduced, based on 1H transverse relaxation time (T 2). The T 2 weighted NMR signal, obtained by a CPMG pulse sequence and processed by chemometric methods was able to determine the oil quality in intact seeds by its fatty composition, cetane number, iodine value and kinematic viscosity with a correlation coefficient r > 0.9. The automated system has the potential to analyze more than 1000 samples per hour and is a powerful tool to speed up the selection of high quality oilseeds for food and biodiesel applications

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.

    Since the advent of electronic computers, people have struggled to develop effective software engineering processes. While these processes are similar to those used by hardware engineers, the software industry has earned a reputation for late delivery of inadequate products. Most software managers are looking for ways to deliver quality products faster, or with fewer resources. The development time and product outcome of any software project can be influenced by four variables: the product characteristics, the people involved, the processes they use, and the underlying technology. In order to have an impact on the productivity of a software development effort, the manager must focus on and balance these areas. This paper will discuss effective ways to improve productivity by using this approach.

  17. Neuron Image Analyzer: Automated and Accurate Extraction of Neuronal Data from Low Quality Images.

    Science.gov (United States)

    2015-01-01

    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.

  2. A deterministic aggregate production planning model considering quality of products

    International Nuclear Information System (INIS)

    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.

    The aperitif wine, known as vermouth, is primarily prepared by adding a mixture of herbs and spices or their extract to a base wine. As such, it could also be called aromatized liquor, or a fortified wine. Various plant parts, such as seeds, wood, leaves, bark, or roots in dry form can be used in flavoring. These additives may be infused, macerated, or distilled in a base white wine, or added at various stages of preparation. The final liquid is filtered, pasteurized, and fortified (by the addition of alcohol). Some vermouths are sweetened, whereas other are left unsweetened (dry vermouth). These tend to have a bitterish finish. The two versions differ in alcohol content as well. Vermouths are most commonly prepared from grape-based wines, but fruit-based wines made from mango, apple, plum, sand pear, and wild apricot may also be used. These possess distinct physicochemical and sensory qualities from standard vermouths. The review gives comprehensive information on the historical developments and technology of vermouth production, the various spices and herbs used in its production, and its quality characteristics. In addition, the chapter also discusses the commercial potential of nongrape fruits in vermouth production. PMID:21867897

    Full Text Available The management of pasture, through the use of appropriate stocking rates and grazing systems, influences the feeding behaviour of the animals. The impact of animal behaviour on vegetation can be of great importance for the sustainability of pastures and mantaining their biodiversity. Indeed, a different response in terms of quality of animal products is mediated by the ability of animals to concentrate or transform grass components, according to the characteristics of the soil. The herbage ingested by animals provides them with compounds with aromatic characteristics, such as terpenes, and with functional properties beneficial for human health, such as carotenoids, vitamins, polyphenols and polyunsatured fatty acids. The combination of different ecological conditions on different soils through specific management practices determines the differentiation of several pasture vegetation types, a unique patrimony of great value in terms of biodiversity and capability to sustain local production, also important because of their own high added value. This review deals with pasture management aimed at conserving the soil and reducing gas emissions, and takes into consideration the quality of animal products as a result of such management.

  13. Microbiological Quality of Some Major Fishery Products Exported from India

    International Nuclear Information System (INIS)

    The export quality marine and aquaculture fish and fishery products were collected from European Union Approved (EUA) and EU-non-approved (EUN) plants located at east and west coast of India and were analysed for the presence of human bacterial pathogens using standard bacteriological techniques. A total of 126 samples comprising of 26 marine shrimp (Penaeus indicus), 18 freshwater prawn, scampi (Macrobrachium rosenbergii), 40 squid (Loligo sp.), six cuttle fish (Sepia sp.), 30 rohu (Lobia rohita) and six long fin herring (Citrocentrus sp.) were analysed. The samples were screened for aerobic plate count (APC) and pathogens including Salmonella spp., Vibrio cholerae, Vibrio parahaemolyticus, Staphylococcus aureus, Escherichia coli, Listeria monocytogenes, and Yersinia enterocolitica. It was observed that the marine products from EUN plants were of poorer microbiological quality as compared with products from EUA plants. Samples of squid (40%) and shrimp (28.5%) from EUN plants were found to be contaminated with Salmonella. However, V. cholerae, L. monocytogenes, and, Y. enterocolitica were not detected in any of the samples tested. Shrimp samples (28%) from EUN plants were positive for Vibrio parahaemolyticus. Shrimp (14.3%) and squid (40%) were also contaminated with coagulase positive S. aureus. Salmonella contamination was observed in 16.7% of the cuttle fish samples from EUN plants. Whole herring samples were of acceptable microbiological quality. Of the freshwater items analyzed, whole rohu samples had higher microbial load as compared to processed rohu samples. All the rohu samples were free from the pathogens, however, 25% of the rohu steak samples had E. coli exceeding the limit of 20 cfu/g. Both whole as well as headless scampi harboured higher microbial load; whole (50%) and headless (41%) scampi samples were contaminated with Salmonella spp. The results suggested a need for implementation of better hygienic practices for the improvement of microbial

  17. Longitudinal beta regression models for analyzing health-related quality of life scores over time

    Directory of Open Access Journals (Sweden)

    Hunger Matthias

    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.

    2013-09-01

    This contribution describes characterization, classification, production, application and quality assurance of Refuse Derived Fuels (RDFs) that are increasingly used in a wide range of co-incineration plants. It is shown in this paper, that the fuel-parameter, i.e. net calorific value [MJ/kg(OS)], particle size d(90) or d(95) [mm], impurities [w%], chlorine content [w%], sulfur content [w%], fluorine content [w%], ash content [w%], moisture [w%] and heavy metals content [mg/kg(DM)], can be preferentially used for the classification of different types of RDF applied for co-incineration and substitution of fossil-fuel in different industial sectors. Describing the external production of RDF by processing and confectioning of wastes as well as internal processing of waste at the incineration plant, a case study is reported on the application of RDF made out of different household waste fractions in a 120,000t/yr Waste to Energy (WtE) circulating fluidized bed (CFB) incinerator. For that purpose, delivered wastes, as well as incinerator feedstock material (i.e. after internal waste processing) are extensively investigated. Starting with elaboration of sampling plan in accordance with the relevant guidelines and standards, waste from different suppliers was sampled. Moreover, manual sorting analyses and chemical analyses were carried out. Finally, results of investigations are presented and discussed in the paper. PMID:23746983

    In a probabilistic risk assessment (PRA) it has been recognized that a core meltdown accident with a large amount of fission products released to the environment is a dominant contributor to public risk. For the evaluation of the risk, information about source terms are inevitable. In order to analyze fission product transport behavior and to evaluate source terms during a core meltdown accident, the ART code has been developed. The ART code has the following features: (1) It can treat fission product transport behavior both in a primary system and a containment system, (2) It models fission product transport caused by both gas flow and liquid flow, and (3) It includes a detailed model about transport behavior of aerosols which are released in quantity during a core meltdown accident. This report is a user's manual for the ART code and includes description of modeling, input/output data and a sample run. (author)

  7. Perceptual difference paradigm for analyzing image quality of fast MRI techniques

    Science.gov (United States)

    Wilson, David L.; Salem, Kyle A.; Huo, Donglai; Duerk, Jeffrey L.

    2003-05-01

    We are developing a method to objectively quantify image quality and applying it to the optimization of fast magnetic resonance imaging methods. In MRI, to capture the details of a dynamic process, it is critical to have both high temporal and spatial resolution. However, there is typically a trade-off between the two, making the sequence engineer choose to optimize imaging speed or spatial resolution. In response to this problem, a number of different fast MRI techniques have been proposed. To evaluate different fast MRI techniques quantitatively, we use a perceptual difference model (PDM) that incorporates various components of the human visual system. The PDM was validated using subjective image quality ratings by naive observers and task-based measures as defined by radiologists. Using the PDM, we investigated the effects of various imaging parameters on image quality and quantified the degradation due to novel imaging techniques including keyhole, keyhole Dixon fat suppression, and spiral imaging. Results have provided significant information about imaging time versus quality tradeoffs aiding the MR sequence engineer. The PDM has been shown to be an objective tool for measuring image quality and can be used to determine the optimal methodology for various imaging applications.

    International Nuclear Information System (INIS)

    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.

  9. Production and quality control of 166 Ho

    International Nuclear Information System (INIS)

    Full text: Radioisotope production is one of the most important sectors in the mid and long term program of nuclear technology development. Therapeutic radiopharmaceuticals allow nuclear physicians to treat disease by attacking only the affected cells. The advantage of nuclear therapeutic over other therapies is that nuclear therapy can eliminate cancerous cells almost without harming healthy cells. Nuclear therapy would greatly improve quality of live by lowering the overall cost of the hospital, and reducing the time a patient stays in the hospital, and reducing the pain and suffering experienced by the patient. Several new radionuclides and carriers have recently been studied for treatment of various joint disorders. Ho-166 is a radionuclide with excellent physical properties for therapeutic application. Holmium-166 is produced by neutron capture on 100% abundant, stable holmium-165 with thermal neutron and resonance neutron cross section of 61.2 barns, respectively. It decays with 26.83 h half-life by emission of 1.855 MeV(51%) and 1.776 MeV (48%). Ho-166 also emits 80.5 keV gamma-ray in 6.2% abundance and, thus, is imageable by conventional techniques. Holmium-166 is utilized in radiotherapeutic applications such as radioimunospecific pharmaceuticals, bone marrow ablation, and radiation synovectomy. The radionuclide 166Ho is successfully produced by 165Ho (n,γ)166Ho reaction in the Nuclear Research Reactor (5 MW) at the neutron flux density 5*1013 n.cm-2.s-1. This study was focused to the preparation and quality control (especially of the radiochemical and radionuclide control) of the 166Ho. References: 1.

    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. Extrinsic quality perception increases to a greater extent the effect of displays due

Finally, two ideological tendencies for the understanding of quality in higher education are presented: quality as productivity and quality as social responsibility.

  7. Role of configuration management in improving quality of metal products

    International Nuclear Information System (INIS)

    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)

  8. 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

    1989-01-01

    Does the perceived expense of a new product's advertising campaign influence expectations about the product's quality? This article conceptualizes the process by which perceived advertising expense acts as a cue to quality. Results from six experiments indicate that under some conditions, knowledge of cost-related campaign elements can evoke advertising expense inferences the influence quality predictions, and these inferences may be spontaneous.

    2012-01-01

    This study examines the use of intrinsic and extrinsic cues in beef quality perception at the point of purchase and upon consumption by consumers with varying levels of familiarity with a particular beef product. High-familiarity consumers tend to use the color of the meat to assess beef quality......, whereas low-familiarity consumers tend to believe that the brand is the most valid cue for assessing beef quality. However, due to the lack of consistency in sensory beef quality, high-familiarity consumers’ ability to form quality expectations that are predictive of their quality experience is no better...

    representation of hydropower is included and total hydro power production for each area is calculated, and the production is distributed among all available plants within each area. During simulation, the demand is affected by prices and temperatures. 6 different infrastructure scenarios of wind and power line development are analyzed. The analyses are done by running EMPS calibrated for today's situation for 11*11*8 different combinations of altered weather variables (temperature, precipitation and wind) describing different climate change scenarios, finding the climate response function for every EMPS-variable according the electricity production, such as prices and income, energy balances (supply, consumption and trade), overflow losses, probability of curtailment etc .

  1. Production process and quality control for the HTTR fuel

    International Nuclear Information System (INIS)

    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.

    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

    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.

    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. Keywords: software quality, development skill, software metrics

    All mass streams from separations and fuel fabrication are products that must meet criteria. Those headed for disposal must meet waste acceptance criteria (WAC) for the eventual disposal sites corresponding to their waste classification. Those headed for reuse must meet fuel or target impurity limits. A “loss” is any material that ends up where it is undesired. The various types of losses are linked in the sense that as the loss of transuranic (TRU) material into waste is reduced, often the loss or carryover of waste into TRU or uranium is increased. We have analyzed four separation options and two fuel fabrication options in a generic fuel cycle. The separation options are aqueous uranium extraction plus (UREX+1), electrochemical, Atomics International reduction oxidation separation (AIROX), and melt refining. UREX+1 and electrochemical are traditional, full separation techniques. AIROX and melt refining are taken as examples of limited separations, also known as minimum fuel treatment. The fuels are oxide and metal. To define a generic fuel cycle, a fuel recycling loop is fed from used light water reactor (LWR) uranium oxide fuel (UOX) at 51 MWth-day/kg-iHM burnup. The recycling loop uses a fast reactor with TRU conversion ratio (CR) of 0.50. Excess recovered uranium is put into storage. Only waste, not used fuel, is disposed – unless the impurities accumulate to a level so that it is impossible to make new fuel for the fast reactor. Impurities accumulate as dictated by separation removal and fission product generation. Our model approximates adjustment to fast reactor fuel stream blending of TRU and U products from incoming LWR UOX and recycling FR fuel to compensate for impurity accumulation by adjusting TRU:U ratios. Our mass flow model ignores postulated fuel impurity limits; we compare the calculated impurity values with those limits to identify elements of concern. AIROX and melt refining cannot be used to separate used LWR UOX-51 because they cannot

    Full Text Available Despite the rapid advance of the software industry, there are still defi ciencies in the quality of the products developed. There are various models and standards that can provide a basis for assessing the quality of software products. In this sense it is diffi cult for an organization to identify which is the most appropriate according to their characteristics, since most studies analyze very few models use a few criteria. This work aims to analyze a set of models and standards aimed at assessing the quality of software products in order to identify those that have been used or referenced, and aspects that characterize each. From the literature a set of criteria that were the basis for comparative analysis, among which are identified: quality characteristics and sub-characteristics, structure, purpose, separation of internal and external elements, relationships between quality characteristics, relationships between quality metrics and quality characteristics, type of project to which it applies, classifi cation type and type of quality assessed. As a result is based on the selection of the ISO / IEC 9126 and ISO / IEC 25010, as the more comprehensive standards taking into account the various approaches used in the comparison.

  5. ISO 9000. Guidelines to increased costs and reduced product quality

    International Nuclear Information System (INIS)

    Many US companies are considering being registered to the provisions of ISO 9000, International Standards for Quality Management. One important problem with the document is that ISO 9000 is not focused on control of product quality. The quality assurance rules established in ISO 9000 have been used in the US for more than 25 years with disastrous financial consequences and little, if any, improvement in quality and safety. These rules are so reliant on documentation and strict compliance that ensuring products comply with specifications has become a secondary issues. That is not what was intended, but it is the result. ISO 9000 program can work effectively only when the top executive responsible for engineering or production takes full responsibility for interpretation and implementation of the quality assurance program. 3 refs., 1 tab

  6. 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

    Full Text Available In recent times the SA Defence Force (SADF has been bombarded with a variety of methods and approaches to the improvement of productivity, financial savings and, most recently, for quality of work life or quality assurance. Various approaches have included the concepts of Total Quality Management (TQM, Quality Circles (and variants in the guise of Triads and others, Methodology, Unit Management Systems, Cost Control Systems, Deterministic Productivity Accounting and the Iike. There have been many benefits to be found in these various approaches, each of which concentrates on certain aspects of productivity. That there have been great achievements in productivity in the SADF is a matter of record, a record which is reflected in a National Award for Productivity, a smaller more efficient SADF, and a reputation for submitting more recommendations for improvements than other departments in the Public Service. At a more personal level though, the writer has gained the impression that no or very little attempt has been made to integrate selected aspects of these approaches into an overall "productivity” strategy acceptable to the SADF. That there is a need for such an overall strategy is clear from the sentiments expressed recently by the members of the SADF's Productivity Co-ordination Committee when attempting to indicate the way ahead to even greater productivity in the SADF (Meeting, January 1991. In this paper a strategy for the improvement of productivity and the quality of work life which is acceptable to the SADF is proposed.

    Full Text Available The definition of the effective allocation of sources is very difficult since the term of efficiency has different meanings attached in the theory and the practice. The aim of this article is to evaluate the effectiveness of expended production inputs by selected entities working on land with the use of the production analysis. The presented highly specialized issue fills the void in this field of study for the period at the turn of the millennium that was specific in its transformation and integration processes related to the accession of the Slovak Republic to the European Union. We presume that the transformation process of the Slovak economy from the centrally planned economy into the market economy was not completed in the analyzed period and left its marks in the form of ineffective allocation of production factors in the sphere of the agricultural basic industry. This analysis of production function and cost optimum confirmed our assumption. In addition to the search for the effective allocation of production resources in the selected period, it is possible to state that the monitored group of companies did not reach the cost optimum in the production. The achievement of the optimal allocation of production resources would be reached by the monitored group only in case of decreased number of employees and increased intensification factors in production.

  1. PRODUCTION OF HIGH QUALITY LUBRICATING BASE OIL

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    @@High VI lubricating oil is produced in hydrocracker through hydrocracking (HDC) and hydroisome-rization reactions. In order to effectively produce high VI component, such as iso-pafaffins and monocyclic naphtenes, it is important to load suitable HDC catalysts and operate them in the appropriate reaction conditions.   Nippon Mitsubishi Oil Corporation (NMOC) and its affiliate company, Nippon Mitsubishi Petroleum Refining Company (NMPRC) reported their original HDC catalysts four years ago in this Japan-China joint se-minar in Beijing[1]. NMOC and NMPRC operate their hydrocracker both in fuel oil production mode and in lubricating oil production mode. In lubricating oil production mode, high VI lubricating oil called VHDC are produced.   In this paper, at first, the advantages of high VI lubricating oil are described. And then it is announced that NMOC and NMPRC have developed a new generation of HDC catalyst with higher cracking activity, higher middle distillate selectivity and longer life than the other commercial HDC catalysts. In addition to those properties, the catalyst is able to yield high VI lubricating oil as well.

    2011-07-29

    Technological changes and improved electronic communications seem, paradoxically, to be making cities more, rather than less, important. There is a strong correlation between urbanization and economic development across countries, and within-country evidence suggests that productivity rises in dense agglomerations. But urban economic advantages are often offset by the perennial urban curses of crime, congestion and contagious disease. The past history of the developed world suggests that these problems require more capable governments that use a combination of economic and engineering solutions. Though the scope of urban challenges can make remaining rural seem attractive, agrarian poverty has typically also been quite costly. PMID:21798941

  18. Analyzing the extents of Basaka Lake expansion and soil and water quality status of Matahara irrigation scheme, Awash Basin (Ethiopia)

    International Nuclear Information System (INIS)

    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)

    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. PMID:25897517

    A combination of rapid prototyping processes (3D Systems' stereolithography and Sanders Prototyping's ModelMaker) are combined with gelcasting to produce high quality silicon nitride components that were performance tested under simulated use conditions. Two types of aerospace components were produced, a low-force rocket thruster and a simulated airfoil section. The rocket was tested in a test stand using varying mixtures of H2 and O2, whereas the simulated airfoil was tested by subjecting it to a 0.3 Mach jet-fuel burner flame. Both parts performed successfully, demonstrating the usefulness of the rapid prototyping in efforts to effect materials substitution. In addition, the simulated airfoil was used to explore the possibility of applying thermal/environmental barrier coatings and providing for internal cooling of ceramic parts. It is concluded that this strategy for processing offers the ceramic engineer all the flexibility normally associated with investment casting of superalloys.

  6. 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

  7. Analyzing production potential of selected food and legume crops for food security in Punjab, Pakistan

    International Nuclear Information System (INIS)

    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)

    International Nuclear Information System (INIS)

    The half-lives of the positron-emitting radioisotopes, carbon-11 (t1/2 = 20.3 min) and fluorine-18 (t1/2 = 109.6 min), preclude lengthy techniques from the routine analysis of radiopharmaceuticals derived for positron emission tomography (PET). Therefore, the assurance of radiopharmaceutical quality, with respect to safety and efficacy, should rely heavily on establishing a well-defined production protocol that delivers a high quality product from materials of specified grade. Also, this protocol should be supported routinely by rapid quality control procedures. Such a combination constitutes good manufacturing practice (GMP) in radiopharmaceutical production for PET. This talk will describe the application of GMP, in a PET centre regularly producing a wide range of 11C- and 18F-radiopharmaceuticals

    To analyze China's fluctuating situation of the factor input and aggregative productivity is not only the main method to seek the source of the economic growth but also the main way to weigh the level of economic growth quality. As to economic growth of a country, the improvement of the productivity is extremely important. The growth of the output can be realized through two kinds of ways: increasing the quantity of factor input of orimproving the effciency of the input and output. Therefore, the level of economic growth quafity does not mainly depend on the amount of invesTed factor, but the importance of improving the produtivity since Pesources are rare.The relative improvement of efficiency in use of the invested factor marks the economic growing quality. So, in order to understand the economic growth quafity of China to some extent, it must analyze Chinese factor input and aggregative productivity. This is the main topic that this text wilt be probed into.

    Full Text Available The objective of this in vivo pilot study was to investigate whether differential biomarker analysis from skin tape strips could be used, not only to evaluate the difference between treated and untreated skin, but also to evaluate the effect of different product treatments. 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.

    2011-12-01

    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.

  9. Quality control and quality standards for the production of bone allografts in China

    International Nuclear Information System (INIS)

    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

  10. 信息动态%Diagnosis and Detection of Critical Quality Resources for Complex Products Based on Supplier GERT Model

    Institute of Scientific and Technical Information of China (English)

    2011-01-01

    The success of leading products depends on the quality of the entire supply chain. Improving the quality of the entire supply chain can help a company stay competitive in today's complex product market. In order to understand the importance of critical quality resources in the complex product supply chain, this study adopts the supplier graph evaluation and review technology (S-GERT) model to assess the quality loss between suppliers. Based on the S-GERT model, we propose a relative algorithm and use it to diagnose quality fluctuations on the supplier side and detect critical quality resources in a complex supply chain.In the first part of this paper, we formulated the Artiles-leon Quality Loss Function, a supplier multi-variety quality loss function to measure the quality loss values of suppliers. In the second part, we analyzed the quality loss delivering principal between upstream and downstream suppliers. In the third part, we researched the parallel and hybrid system structures to detect the fluctuation of supplier's quality and diagnose critical quality resources. In the fourth part, we used a pattern aircraft production system to examine the quality of suppliers. Our study showed that the quality management of complex products on the supplier side is one of core problems in the supply chain management area. The quality loss can be accumulated in the complex paths between suppliers because of the complexity of managing supply chain networks.From the perspective of quality loss delivery, the proposed supplier GERT model and detection algorithm design provide a new research method to understand quality management in the “main manufacturer-supplier” production system.

    Micotti, Marco; Pianosi, Francesca; Bizzi, Simone; Mason, Emanuele; Weber, Enrico

    2014-05-01

    In many countries water is a key renewable resource to complement carbon-emitting energy production in the face of demand pressure from fast-growing industrial production and urbanization. In this study, we analyze the case of the Red River Vietnam, a large basin of 169.000 kmq where the storing capacity, mainly targeted at hydropower production, has steadily increased since from the Eighties through the construction of a number of reservoirs (Hoa Binh completed in 1994, Tuyen Quang in 2008, Son La in 2012), which nowadays account for the 15% of the national electric power production. On the other hand, reservoir operation dramatically alters downstream river hydrology, geomorphological processes and riverine ecosystems. In this work, we focus in particular on the alteration of the hydrological regime downstream of the Hoa Binh reservoir and explore re-operation options to mitigate the hydrological alteration while guaranteeing reasonable hydropower production. To reach this goal we (i) define an index of hydrological alteration starting from the well established set of Indicators of Hydrological Alteration and applying a novel selection and aggregation procedure; (ii) embed such an index into a multi-objective optimization process, to design reservoir operating policies that represent Pareto-optimal solutions between maximization of hydropower production and minimization of hydrological alteration. This work demonstrates the potential of multi-objective optimization and simulation tools to analyze tradeoffs between conflicting needs and thus support the evaluation and planning of sustainable energy production programs.

    2010-01-01

    Context: 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. Methods: The arguments in this article apply new reasoning to the previous literature. Findings: The method used in this article to classify health care provision distinguishes different types of health problems that share generic constraints of production. Conclusions: 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. PMID:21166870

  17. Variability in sunflower oil quality for biodiesel production: A simulation study

    International Nuclear Information System (INIS)

    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

    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

  8. Sensory and microbial quality of irradiated crab meat products

    International Nuclear Information System (INIS)

    Low dose gamma irradiation has proved effective in reducing pathogenic and spoilage microorganisms in a variety of seafood products. However, little information is available on the effect of irradiation on the sensory quality and consumer acceptance of such products. We compared microbial and sensory quality of irradiated (2 kGy or less) crab products (white lump, claw, and fingers) through 14-days of ice-storage. Irradiation effectively reduced spoilage bacteria extending shelf-life by more than 3 days beyond control samples. During storage, fresh crab odor and flavor were similar for treated and control samples, while off-flavors and odors developed more rapidly in controls. Overall acceptability scores for irradiated crab samples were higher than for control samples throughout 14-days ice storage

    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. PMID:26980703

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

    International Nuclear Information System (INIS)

    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.

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.

    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

    Full Text Available 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

    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

    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.

    Field, R A; Soltis, J; Murphy, S

    2014-05-01

    Increased use of hydraulic fracturing ("fracking") in unconventional oil and natural gas (O & NG) development from coal, sandstone, and shale deposits in the United States (US) has created environmental concerns over water and air quality impacts. In this perspective we focus on how the production of unconventional O & NG affects air quality. We pay particular attention to shale gas as this type of development has transformed natural gas production in the US and is set to become important in the rest of the world. A variety of potential emission sources can be spread over tens of thousands of acres of a production area and this complicates assessment of local and regional air quality impacts. We outline upstream activities including drilling, completion and production. After contrasting the context for development activities in the US and Europe we explore the use of inventories for determining air emissions. Location and scale of analysis is important, as O & NG production emissions in some US basins account for nearly 100% of the pollution burden, whereas in other basins these activities make up less than 10% of total air emissions. While emission inventories are beneficial to quantifying air emissions from a particular source category, they do have limitations when determining air quality impacts from a large area. Air monitoring is essential, not only to validate inventories, but also to measure impacts. We describe the use of measurements, including ground-based mobile monitoring, network stations, airborne, and satellite platforms for measuring air quality impacts. We identify nitrogen oxides, volatile organic compounds (VOC), ozone, hazardous air pollutants (HAP), and methane as pollutants of concern related to O & NG activities. These pollutants can contribute to air quality concerns and they may be regulated in ambient air, due to human health or climate forcing concerns. Close to well pads, emissions are concentrated and exposure to a wide range of

    Landfill leachate recirculation treatment process is a promising and economic way in northeast China due to the distinct season variation. In order to study the impact of recirculation on leachate production and its quality, two simulated sanitary landfill reactors, one with leachate recirculation and the other without, were placed outdoor in Harbin. The two-year experimental results indicated that leachate production was reduced by 86% with leachate recirculation and less or no facility for leachate treatment required. Recirculation could improve the leachate quality dramatically with lower COD, SS, NH4+-N and higher pH level.Recirculation also could enhance waste degradation and stabilization and improve the efficiency of landfill. This study confirmed that leachate recirculation was a very feasible way for on-site landfill leachate treatment in cold areas.

  13. The Peak of the Oil Age - Analyzing the world oil production Reference Scenario in World Energy Outlook 2008

    International Nuclear Information System (INIS)

    The assessment of future global oil production presented in the IEA's World Energy Outlook 2008 (WEO 2008) is divided into 6 fractions; four relate to crude oil, one to non-conventional oil, and the final fraction is natural-gas-liquids (NGL). Using the production parameter, depletion-rate-of-recoverable-resources, we have analyzed the four crude oil fractions and found that the 75 Mb/d of crude oil production forecast for year 2030 appears significantly overstated, and is more likely to be in the region of 55 Mb/d. Moreover, analysis of the other fractions strongly suggests lower than expected production levels. In total, our analysis points to a world oil supply in 2030 of 75 Mb/d, some 26 Mb/d lower than the IEA predicts. The connection between economic growth and energy use is fundamental in the IEA's present modelling approach. Since our forecast sees little chance of a significant increase in global oil production, our findings suggest that the 'policy makers, investors and end users' to whom WEO 2008 is addressed should rethink their future plans for economic growth. The fact that global oil production has very probably passed its maximum implies that we have reached the Peak of the Oil Age.

We add labor market history variables such as experience and firm and industry tenure, as well as general human capital measures such as schooling and sex. Adding these variables decreases the ratio of...... the 90th to 10th productivity quantiles from 3.27 to 2.68 across eight Danish manufacturing and service industries. We also use the wage bill and worker fixed effects. We find that the wage bill explains as much dispersion as human capital measures....

    The worldwide antibiotic crisis has led to a renewed interest in phage therapy. Since time immemorial phages control bacterial populations on Earth. Potent lytic phages against bacterial pathogens can be isolated from the environment or selected from a collection in a matter of days. In addition, phages have the capacity to rapidly overcome bacterial resistances, which will inevitably emerge. To maximally exploit these advantage phages have over conventional drugs such as antibiotics, it is important that sustainable phage products are not submitted to the conventional long medicinal product development and licensing pathway. There is a need for an adapted framework, including realistic production and quality and safety requirements, that allows a timely supplying of phage therapy products for 'personalized therapy' or for public health or medical emergencies. This paper enumerates all phage therapy product related quality and safety risks known to the authors, as well as the tests that can be performed to minimize these risks, only to the extent needed to protect the patients and to allow and advance responsible phage therapy and research.

    Full Text Available Introduction: The use of medicinal plants has risen worldwide. In Iran, herbal waters and rose waters are of traditional medicinal products and as a result, they are widespreadly consumed. Therefore, diagnosis of microbial quality of these products is important. The aim of this study was to evaluate microbial quality of herbal extracts distributed in Kashan, Iran. Methods: In this descriptive study, 256 samples of herbal waters and 191 samples of rose waters (total samples of 447 distributed in Kashan during 2012 to 2013 were purchased and transferred to laboratory. Then microbial tests such as total aerobic bacterial count, mold and yeast count, total coliforms, and detection of Enterococcus, Pseudomonas and sulphite-reducing Clostridia were evaluated based on national standard of Iran. Results: Contamination with Pseudomonas and Enterococcus was observed in the herbal water samples. 196 cases (43.84% of the total samples, 113 cases (44.15% of the herbal waters and 83 cases (43.45% of the rose waters were usable based on the national standard of Iran. Neither herbal waters nor rosewater samples were contaminated by E.Coli and Sulphite-reducing clostridia. Additionally, none of the rosewater samples was contaminated by Coliforms and Pseudomonas. Conclusion: Based on the findings and due to the fact that these products are contaminated with aerobic mesophilic bacteria, mold and yeast, to minimize the risks we recommend to apply pasteurized temperature, high-quality packaging material and hygiene observance in processing time of herbal waters and rose waters.

  5. A quantitative method to analyze the quality of EIA information in wind energy development and avian/bat assessments

    International Nuclear Information System (INIS)

    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

    International Nuclear Information System (INIS)

    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)

    2005-05-01

    Full Text Available The objective of this article is to present the possibilities of the economic exploitation of the buffalo population in Greece through the production of certified quality products. The buffalo population in Greece has decreased dramatically during the last decades, due to the rapidly changing socio-economic conditions, mainly the mechanisation of the agricultural sector. The current study has been undertaken in the region of Kerkini Lake, where the majority of buffalo population of Greece is concentrated. The main characteristics of the production system; feeding based on the natural vegetation, the unique way of product processing and the gastronomy are investigated by filling up questionnaires. The next step includes the detailed description of the production system and the definition of the critical points where the intervention will take place. The proper application of the production protocols will be undertaken by the official organisation for certification. The farmers association will be responsible for the management of the transition of the production system. As the driving force of the new development of buffalo breeding is the production of quality products, further investigation on the special characteristics of milk and meat buffalo products, is required.

    1998-08-01

    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.

  14. Implementation of quality assurance with respect to product quality and scheduling

    International Nuclear Information System (INIS)

    Quality assurance means the whole range of actions which are necessary to meet the client's requirements for the product and the test methods. Audits: The preconditions for fabrication must be fulfilled by approval of the manufacturer's quality assurance system, the staff's qualification, his procedures and his equipments. This is done by means of a system audit at KWU or an equivalent organisation. Specifications: For quality assurance the requirements for the components are fixed in specifications. There are material specifications, process/procedure specifications, components specifications. Approval of Component Design and Manufacture (Scheduling): The approval procedure of a structurally welded part is described as an example of the approval of component design and manufacture, thus representing one small piece of a mechanical equipment. In-Process Surveillance (Product Audit): At KWU the in-process surveillance is regulated by a KQ- or product audit concept. In this concept we have K- and KQ-steps. The list of KQ-steps will be presented. Documentation: All test or examination steps are documented with certificates, lists, and stamps for the final documentation. 19 figs

    International Nuclear Information System (INIS)

    With the MEP subsidy regulation 'Environmental quality of electricity production' The Dutch minister of Economic Affairs focussed mainly on reaching the policy objective of the EU according to which 9% of all electricity used in the Netherlands should be generated with sustainable sources. According to the opinion of the Dutch Court of Audits not enough attention has been paid to the coherence of the MEP regulation with other policy objectives in the area of sustainability, such as air quality and CO2 reduction. The same goes for the effectiveness and the financial management of the MEP regulation. Moreover, the study, which was carried out by request of the Dutch Lower House, demonstrates that it is still uncertain if the policy objective for 2010 will be reached. The report consists of two parts: part 1: Conclusions, recommendations and administrative reactions, and Part 2: Answering Lower House questions.(mk)

  16. The use of a measure with a strong correlation with the visual system to analyze the influence of the acquisition conditions over image quality in panoramic dental images

    International Nuclear Information System (INIS)

    The High Dynamic Range Visible Difference Predictor (HDR-VDP) was created to overcome the poor correlation between objective and subjective digital image quality criteria. This metric has been successfully tested to analyze the effect of medical images compression over image quality. A study using 13 dental panoramic images of an anthropomorphic phantom was carried out. Images were acquired with a digital Kodak equipment. Tube current and beam energy were changed among studies in order to analyze how the image quality was affected by the acquisition parameters variation. The criterion about image quality of two expert observers was taken into account. Furthermore, HDR-VDP was fitted to the problem under analysis. Correlation between the metric and the subjective criterion was also analyzed. HDR-VDP had a correlation of r 0.683 (p = 0. 013) with respect to the subjective criterion. The metric calculated over 9 x 9 pixel windows in regions of interest was able to detect differences in image quality for a typical range of kVp and mA in this type of study. (Author) 17 refs.

    1986-01-01

    An oxygen analyzer which identifies and classifies microgram quantities of oxygen in ambient particulate matter and for quantitating organic oxygen in solvent extracts of ambient particulate matter. A sample is pyrolyzed in oxygen-free nitrogen gas (N.sub.2), and the resulting oxygen quantitatively converted to carbon monoxide (CO) by contact with hot granular carbon (C). Two analysis modes are made possible: (1) rapid determination of total pyrolyzable oxygen obtained by decomposing the sample at 1135.degree. C., or (2) temperature-programmed oxygen thermal analysis obtained by heating the sample from room temperature to 1135.degree. C. as a function of time. The analyzer basically comprises a pyrolysis tube containing a bed of granular carbon under N.sub.2, ovens used to heat the carbon and/or decompose the sample, and a non-dispersive infrared CO detector coupled to a mini-computer to quantitate oxygen in the decomposition products and control oven heating.

    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%.

    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

  3. Product Quality Modelling Based on Incremental Support Vector Machine

    International Nuclear Information System (INIS)

    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.

    Some agricultural industries generate large amounts of low value co-products/residues, including citrus peel, sugar beet pulp and whey protein from the production of orange juice, sugar and cheese commodities, respectively. National Program #306 of the USDA Agricultural Research Service aims to characterize and enhance quality and develop new processes and uses for value-added foods and bio-based products. In parallel projects, we applied scanning microscopies to examine the molecular organization of citrus pectin gels, covalent crosslinking to reduce debonding in sugar beet pulp-PLA composites and functional modification of whey protein through extrusion in order to evaluate new methods of processing and formulating new products. Also, qualitative attributes of fresh produce that could potentially guide germ line development and crop management were explored through fluorescence imaging: synthesis and accumulation of oleoresin in habanero peppers suggest a complicated mechanism of secretion that differs from the classical scheme. Integrated imaging appears to offer significant structural insights to help understand practical properties and features of important food co-products/residues.

    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.

    The adrenocortical human cell line H295R is a valuable tool for screening endocrine disrupting compounds. In general, previous research focus has been on the production of the 2 sex steroids, 17β-estradiol and testosterone, and less attention has been paid to other important steroid end points in the steroidogenesis with a wide range of physiological functions, such as the glucocorticoids (corticosterone and cortisol). A newly developed and validated solid phase extraction (SPE) liquid chromatography-mass spectroscopy (LC-MS/MS) method was used to measure the production of cortisol and corticosterone in the H295R cell line. The method was applied by studying the effects of 2 model endocrine disrupters, ketoconazole and prochloraz, the pharmaceutical budesonide, and the inducer forskolin on the steroid production in this cell line. Dose-response curves were obtained for the correlation between hormone concentrations and the concentration of the individual disruptors. Exposing cells to ketoconazole resulted in a decrease in cortisol and corticosterone concentrations in a dose-dependent manner with EC₅₀ values of 0.24 and 0.40 μmol/L, respectively. The same applied for cells exposed to prochloraz with EC₅₀ values of 0.06 and 0.09 μmol/L for cortisol and corticosterone, respectively. Budesonide also inhibited glucocorticoid secretion. The EC₅₀ value for cortisol was 19.50 μmol/L, whereas the EC₅₀ value for corticosterone was 71.42 μmol/L. Forskolin induced the secretion of both cortisol (EC₅₀ = 4.09 μmol/L) and corticosterone (EC₅₀ = 0.28 μmol/L). The results obtained demonstrated the validity of the method. Based on these findings, quality criteria for the production of these steroids in this cell line were suggested. PMID:23616146

    As complicated mixture systems, chemical components of Angelica are very difficult to identify and discriminate, so as not to control its quality effectively. In recent years, Mid-infrared spectroscopy has been innovatively employed to identify and assess the quality of Traditional Chinese medicine (TCM) products. In this paper, the macroscopic IR fingerprint method including Fourier transform infrared spectroscopy (FT-IR), the second derivative infrared spectroscopy (SD-IR) and two-dimensional correlation infrared spectroscopy (2D-IR), are applied to study and identify Angelica raw material, the decoction and different segmented production of AB-8 macroporous resin. FT-IR spectrum indicates that Angelica raw material is rich in sucrose and the correlation coefficient is 0.8465. The decoction of Angelica contains varieties of polysaccharides components and the content is gradually decreased with increasing concentration of ethanol. In addition, the decoction of Angelica contains a certain amount of protein components and 50% ethanol eluate has more protein than other eluates. Their second derivative spectra amplify the differences and reveal the potentially characteristic IR absorption bands, then we conclude that the decoction of Angelica contains a certain amount of ferulic acid and ligustilide. And 30% ethanol eluate, 50% ethanol eluate and 70% ethanol eluate are similar to ligustilide. Further, 2D-IR spectra enhance the spectral resolution and obtain much new information for discriminating the similar complicated samples. It is demonstrated that the above three-step infrared spectroscopy could be applicable for effective, visual and accurate analysis and identification of very complicated and similar mixture systems of traditional Chinese medicines.

    Full Text Available In order to determine the safety of milk produced by smallholder dairy goat farms, a farm-based research study was conducted on commercial dairy goat farms to compare the microbiological quality of milk produced using 3 different types of dairy goat production systems (intensive, semi-intensive and extensive. A survey of dairy goat farms in and around Pretoria carried out by means of a questionnaire revealed that most of the smallholder dairy goat farms surveyed used an extensive type of production system. The method of milking varied with the type of production system, i.e. machine milking; bucket system machine milking and hand-milking, respectively. Udder half milk samples (n=270 were analysed, of which 31.1 % were infected with bacteria. The lowest intra-mammary infection was found amongst goats in the herd under the extensive system (13.3 %, compared with 43.3 % and 36.7 % infection rates under the intensive and semi-intensive production systems, respectively. Staphylococcus intermedius (coagulase positive, Staphylococcus epidermidis and Staphylococcus simulans (both coagulase negative, were the most common cause of intramammary infection with a prevalence of 85.7 % of the infected udder halves. The remaining 14.3 % of the infection was due to Staphylococcus aureus. Bacteriology of bulk milk samples on the other hand, showed that raw milk obtained by the bucket system milking machine had the lowest total bacterial count (16 450 colony forming units (CFU/mℓ compared to that by pipeline milking machine (36 300 CFU/mℓ or handmilking (48 000 CFU/mℓ. No significant relationship was found between the somatic cell counts (SCC and presence of bacterial infection in goat milk. In comparison with the herds under the other 2 production systems, it was shown that dairy goat farming under the extensive production system, where hand-milking was used, can be adequate for the production of safe raw goat milk.

    There are many different perspectives about the sustainable agriculture, which had been proposed since the last three decades in the world. While China's ecologists and agronomists proposed a similar concept named 'ecological agriculture'. Although ecological agriculture in China has achieved substantial progress, including theory, models and supporting technologies nearly several decades of practice and development, its application guidance still is not yet clear. The organic agriculture model proposed by European Union is popular, but it is limited in the beneficiary groups and the social and ecological responsibility. In this context, the article based on an ecological point of view, analyzed the shortcomings of ecological imbalance caused by a single mode of agricultural production and the negative impact on the quality of agricultural products, and discussed the core values of ecological agriculture. On this basis, we put forward the concept of sustainable security of agricultural products. Based on this concept, an agricultural platform was established under the healthy ecosysphere environment, and from this agricultural platform, agricultural products could be safely and sustainably obtained. Around the central value of the concept, we designed the agricultural sustainable and security production model. Finally, we compared the responsibility, benefiting groups, agronomic practices selection and other aspects of sustainable agriculture with organic agriculture, and proved the advancement of sustainable agricultural model in agricultural production quality and safety.

  20. Analyze image quality and comparative study between conventional and computed radiography applied to the inspection of alloys

    International Nuclear Information System (INIS)

    Piping system design takes into account relevant factors such as: internal coating, dimensioning, vibration system, adequate supports and principally, piping material. Cost is a decisive factor in the phase of material selection. The non-destructive testing method most commonly employed in industry to analyze the structure of an object is radiographic testing. Computed radiography (CR) is a quicker and much more efficient alternative to conventional radiography but, although CR presents numerous advantages, testing procedures are still largely based on trial and error, due to the lack of a consecrated methodology to choose parameters as it exists for conventional radiography. Notwithstanding, this paper presents a study that uses the technique of computed radiography to analyze metal alloys. These metal alloys are used as internal pipe coating aiming to protect against corrosion and cracks. This study seeks to evaluate parameters such as basic spatial resolution, Normalized Signal-to-Noise Ratio (SNRN), contrast, intensity and also to compare conventional radiography with CR. (author)

    Ubiquitous computing (or Ambient Intelligence) promises a world in which information is available anytime anywhere and with which humans can interact in a natural, multimodal way. In such world, perceptual image quality remains an important criterion since most information will be displayed visually, but other criteria such as enjoyment, fun, engagement and hedonic quality are emerging. This paper deals with engagement, the intrinsically enjoyable readiness to put more effort into exploring and/or using a product than strictly required, thus attracting and keeping user's attention for a longer period of time. The impact of the experienced richness of an interface, both visually and degree of possible manipulations, was investigated in a series of experiments employing game-like user interfaces. This resulted in the extension of an existing conceptual framework relating engagement to richness by means of two intermediating variables, namely experienced challenge and sense of control. Predictions from this revised framework are evaluated against results of an earlier experiment assessing the ergonomic and hedonic qualities of interactive media. Test material consisted of interactive CD-ROM's containing presentations of three companies for future customers.

  3. Quality control and functionality tests during ATLAS IBL production

    International Nuclear Information System (INIS)

    To improve performance of the ATLAS inner tracker, a fourth Pixel layer, called the Insertable B-layer (IBL), will be installed on a new beam pipe in 2014. This detector uses both conventional planar and 3D pixel sensors bump-bonded to a new readout chip, the FE-I4, in a novel stave design. Therefore, a production QA test bench has been established to test all production staves before integration with the new beam pipe. This setup combines former ATLAS Pixel services and a new readout system, namely the RCE (Reconfigurable Cluster Element) system developed at SLAC. With this setup all production staves will be tested to ensure the installation of only those staves which fulfill the IBL criteria. Quality assurance measurements under cleanroom conditions, including temperature and humidity control, are performed during the various production steps of the IBL, namely connectivity as well as electrical tests and signal probing on assembled subsystems. The capabilities of the stave qualification setup, and recent results from testing prototype staves are presented and discussed.

    Seal leak test part is a polyurethane material-based product. Based on past data, defect level of this product was 8%, higher than the target of 5%. Quality improvement effort was done using six sigma method that included phases of define, measure, analyse, improve, and control. In the design phase, a Delphi method was used to identify factors that were critical to quality. In the measure phase, stability and process capability was measured. Fault tree analysis (FTA) and failure mode and effect analysis (FMEA) were used in the next phase to analize the root cause and to determine the priority issues. Improve phase was done by compiling, selecting, and designing alternative repair. Some improvement efforts were identified, i.e. (i) making a checklist for maintenance schedules, (ii) making written reminder form, (iii) modifying the SOP more detail, and (iv) performing a major service to the vacuum machine. To ensure the continuity of improvement efforts, some control activities were executed, i.e. (i) controlling, monitoring, documenting, and setting target frequently, (ii) implementing reward and punishment system, (iii) adding cleaning tool, and (iv) building six sigma organizational structure.

    Quality/Productivity Improvement (QPI) initiatives in the engineering environment at McDonnell Douglas-Houston include several different, distinct activities, each having its own application, yet all targeted toward one common goal - making continuous improvement a way of life. The chief executive and the next two levels of management demonstrate their commitment to QPI with hands-on involvement in several activities. Each is a member of a QPI Council which consists of six panels - Participative Management, Communications, Training, Performance/Productivity, Human Resources Management and Strategic Management. In addition, each manager conducts Workplace Visits and Bosstalks, to enhance communications with employees and to provide a forum for the identification of problems - both real and perceived. Quality Circles and Project Teams are well established within McConnel Douglas as useful and desirable employee involvement teams. The continued growth of voluntary membership in the circles program is strong evidence of the employee interest and management support that have developed within the organization.

    What we have been reviewing is a workplace ethic of excellence, a management philosophy that has at its core a creative orientation that encourages diversity of vision that drives risk taking, participation, and collaborative employee endeavors within the context of shared rewards. To achieve this ethic of excellence in an industry battered by socio-eco-political and ethical hurricanes, we need to be genuflecting at the altar of opportunity and engaging in brainstorming, not only about the future, but also how we are going to get there. We need to abandon the reflex of engaging in crisis management. Health care management must assume the role of coach, mentor, and visionary, thus shedding the inane propensity to move along the comfortable road of bureaucracy, cynicism, redundancy, and control. Our future lies in a proactive, organizationally integrated, customer-oriented, and enabling environment that delivers high quality standards that maximize productivity. Therefore, in a world of change, there must be a marriage between quality improvement and productivity through implementation of QIPP processes and culture. PMID:10127558

  7. Liposomal Drug Products: A Quality by Design Approach

    Science.gov (United States)

    Xu, Xiaoming

    Quality by Design (QbD) principles has been applied to the development of two liposomal formulations, containing a hydrophilic small molecule therapeutic (Tenofovir) and a protein therapeutic (superoxide dismutase). The goal of the research is to provide critical information on 1) how to reduce the preparation variability in liposome formulations, and 2) how to increase drug encapsulation inside liposomes to reduce manufacturing cost. Most notably, an improved liposome preparation method was developed which increased the encapsulation efficiency of hydrophilic molecules. In particular, this method allows for very high encapsulation efficiency. For example, encapsulation efficiencies of up to 50% have been achieved, whereas previously only 20% or less have been reported. Another significant outcome from this research is a first principle mathematical model to predict the encapsulation efficiency of hydrophilic drugs in unilamellar liposomes. This mathematical model will be useful in: formulation development to rapidly achieve optimized formulations; comparison of drug encapsulation efficiencies of liposomes prepared using different methods; and assisting in the development of suitable process analytical technologies to achieve real-time monitoring and control of drug encapsulation during manufacturing. A novel two-stage reverse dialysis in vitro release testing method has also been developed for passively targeted liposomes, which uses the first stage to mimic the circulation of liposomes in the body and the second stage to imitate the drug release process at the target. The developed in vitro release testing method can be used to distinguish formulations with varied compositions for quality control testing purposes. This developed method may pave the way to the development of more biorelevant quality control testing methods for liposomal drug products in the future. The QbD case studies performed in this research are examples of how this approach can be used to

    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

    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.

    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)

    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

    Soil degradation phenomena include water erosion and physical and biological processes have been already reported in rangelands of southwestern Spain. The increasing of the number of domestic animals since 1986 has been highlighted as one of the key causes. The main goal of this work is to analyze the effects of the excessive number of animals on soil quality and pasture production in privately-owned farms dedicated to extensive ranching. Soil properties, soil surface cover, erosion features, pasture production and composition, rainfall and land management variables such as livestock density were analyzed during a period of 3 years (2008-2011). The study was carried out in 22 fenced units belonging to 10 farms distributed throughout the Spanish region of Extremadura. The occurrence of bare soil patches, and consequently water erosion processes, as well as an increasing in the mean values of bulk density from 5 to 10 cm in depth were observed in the fenced units with animal stocking rates exceeding 1 AU ha-1 (AU: animal cattle equivalent unit). Some indications which may serve to confirm the negative effect of increased bulk density on pasture production and quality were also found.

  15. Quality Control for Expanded Tsetse Production, Sterilization and Field Application

    International Nuclear Information System (INIS)

    The use of the sterile insect technique (SIT) for the control of pest insects as part of an integrated, area-wide approach is widely accepted. Its application for the eradication of different tsetse flies, the vectors of human sleeping sickness and African animal trypanosomosis, is attracting increasing interest. Following several initial demonstrations of the application of the SIT for tsetse control the technique was applied on the island of Unguja, Zanzibar, in the mid-1990s and, as the final component of an integrated control programme, led to the eradication of the only tsetse species on the island, Glossina austeni. This successful programme encouraged a number of countries to embark on projects with an SIT component for tsetse control, most Ethiopia. In 2001 the Pan African Tsetse and Trypanosomosis Eradication Campaign (PATTEC) was launched by the Organization of African Unity (now African Union, AU) and, subsequently, six countries obtained funding from the African Development Bank (AfDB) in 2005 to support control programmes with an SIT component. A further six countries have subsequently requested AfDB funding for their programmes. The FAO/IAEA coordinated research project (CRP) on Automation for Tsetse Mass Rearing For Use in Sterile Insect Technique Programmes, which was completed in 2001, led to the development of a semi-automated system for tsetse production. Using this new system, a large rearing facility was established in Addis Ababa, Ethiopia, to supply sterile males for an elimination programme in the southern Rift Valley. The development of large-scale rearing highlighted the need for improved quality control procedures and, with this in mind, the Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture established a CRP in 2003 entitled Improved and Harmonized Quality Control for Expanded Tsetse Production, Sterilization and Field Application with the Objective of Improving and Expanding the Quality Control Sections of the FAO

  17. Plans of verification tests for the ACTOR code analyzing fission products behavior in primary heat transportation system of FBR

    International Nuclear Information System (INIS)

    The ACTOR is the code to analyze the transfer behavior of fission products (FPs) in the coolant sodium and cover gas, which are released from the fuel plenum or fuel pellets due to a cladding breach caused by temperature increase during an accident. Principal analysis models adopted in the ACTOR code; such as 'FP release model', 'Bubble transfer model in sodium', 'FP transfer model from bubble to sodium' and 'FP adsorption model', are constructed based on the experimental results relating to each phenomenon But, some of the analysis models are still desirable to be verified by experiments considering influence on the evaluation results. This study is planned to carry out the necessary verification tests for the ACTOR code concerning the following phenomena relation to the analysis models. (1) Cesium transfer behavior from inert gas bubble to sodium (2) Cover gas radiation behavior during temperature increase due to decay heat of FPs As for (1), transfer behavior of cesium to coolant in fast reactor is different from that of LWR, because cesium is alkaline metal same as sodium. So, cesium is to be an important fission product in severe accident of fast reactor plant. The analysis model of ACTOR, transfer behavior of cesium to coolant sodium is conducted based on the results of tests carried out by using iodine as fission product, so it is necessary to carry out the tests by using cesium for verification of ACTOR analysis model. As for (2), radiation heat transfer is not considered during cover gas temperature increase in the ACTOR analysis model, because argon applied as cover gas in fast reactor plant is monoatomic molecule. It is necessary to confirm the validity of this analysis model and to investigate a means to control cover gas temperature. This paper will report the test plans and test apparatus of verification tests for the ACTOR code mentioned above. The verification tests will be carried out by Hokkaido University

    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

    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)

    2010-01-01

    Full Text Available The review discusses the topics presented below, with experimental data and more evidence for some aspects which areproblematic for the pig producer. To obtain high quality processed pig products, heavy pig production in Italy is subjectedto rules fixed by several Consortia, on the basis of the experience of producers and the results from scientific research.Slaughter animals of at least 9 months of age and 160 kg live weight are required to provide heavy cuts with excellentmeat. Breeds are limited to Italian Large White and Landrace, selected for specific parameters such as loss at 1st saltingof the ham, and their crosses. Crosses with Duroc and hybrids can be used if obtained from selection and crossingschemes that fit the objectives of Italian selection. Backfat thickness must be “sufficient” to obtain retailed fresh hamswith fat cover ranging from 20 to 30 mm, depending on ham weight, and the content of linoleic acid in ham fat covercannot exceed 15%. Fat quantity and quality in feeds should be carefully controlled to satisfy the quality of fat in theham. The feeding level is also relevant, due to the imposed minimum age at slaughter. Feed restriction is a necessarypractice to respect the rules for ham production. For castrate males of medium genetic value, the restriction shouldreduce fat deposition, but the diet composition can be adapted to maintain the maximum growth of protein. For strainswith high lean deposition potential and particularly for gilts, protein deposition should also be limited to maintain a sufficientfat cover of ham.

    A solvent-free biocatalytic process for the synthesis of high quality cetyl laurate, myristate, palmitate and stearate has been optimized. This enzymatic procedure follows the fundamental principles of the Green Chemistry and lead to sustainable products, which can be labeled as natural and conform to the principal requirements for its use in high value-added goods. The four esters selected are the main components of spermaceti, a mixture of waxes very appreciated in cosmetic and pharmacy because of its physical properties and emolliency, which was formerly extracted from the head of the sperm whales. In this paper, the influence of the amount of biocatalyst, the commercially available Novozym(®) 435, and the temperature were studied in an open-air batch reactor before carrying out the synthesis in a high performance vacuum reactor with dry nitrogen input to shift the equilibrium towards product formation. Under optimal conditions, conversion was higher than 98.5 %. The characterization of the enzymatic cetyl esters puts in evidence that these are ultra-pure compounds, which have similar properties to the ones obtained through the conventional industrial processes with the extra benefit of being environmentally friendly.

  13. Verification of product quality from process control---preliminary results

    International Nuclear Information System (INIS)

    This paper describes how, using reasonable assumptions, a simple model for the West Valley Demonstration Project (WVDP) vitrification process can be constructed. Well-developed statistical ideas are then used to determine the consequences of the expected variations in process control variables, first in terms of glass product composition and then in terms of glass properties. Simple models for melt viscosity and glass chemical durability are presented and show how such models may be combined with the process model to verify product quality. The region most likely encompassing process variations is defined, and by requiring that this lies entirely within the region of acceptable glasses, we arrive at the present WVDP reference composition, WVW-RG4. To the extent that the assumptions described are valid, a point that will be tested at WVDP, it is concluded that the WVDP, as presently characterized, can successfully produce glasses that are both processible and of acceptable durability. Finally, the extensions and refinement of this work in progress are presented. 7 refs., 22 figs., 4 tabs

  14. A study of quality management strategy for reused products

    International Nuclear Information System (INIS)

    To ensure the sustainability, industries have to move forward to product recovery strategies. Reuse is one of the most efficient strategies as it preserves natural resources while maintaining the functional properties of the product. To alleviate the concerns over the quality at the end of first life, laws are enacted to protect the consumers through mandatory warranty requirements. Offering warranty results in additional costs, this cost might be reduced through upgrade that improves the reliability of the item. Considering the age at the end of first life as stochastic, this paper proposes a profit model, relevant costs like upgrade and the minimal repair during the warranty period are included. Optimal upgrade level and warranty length are jointly derived so that the expected profit per used item for the producer can be maximized. Algorithm to search for the optimal solution is developed for a special case. Numerical examples are utilized to demonstrate the feasibility of the proposed approach and the sensitivity analyses regarding the important parameters that might impact the profit

    2004-09-01

    The Center for Space Research (CSR) is exploring new approaches to integrate data collected by the MODerate resolution Imaging Spectroradiometer (MODIS) sensor, flown on NASA's Earth Observing System (EOS) satellites, into a real-time prediction methodology to support operational air quality forecasts issued by the Monitoring Operations Division (MOD) of the Texas Commission on Environmental Quality (TCEQ). Air pollution is a widespread problem in the United States, with over 130 million individuals exposed to levels of air pollution that exceed one or more health-based standards. Texas air quality is under assault by a variety of anthropogenic sources associated with a rapidly growing population along with increases in emissions from the diesel engines that drive international trade between the US and Central America. The challenges of meeting air quality standards established by the Environmental Protection Agency are further impacted by the transport of pollution into Texas that originates from outside its borders and are cumulative with those generated by local sources. In an earlier study, CSR demonstrated the value of MODIS imagery and aerosol products for monitoring ozone-laden pollution that originated in the central US before migrating into Texas and causing TCEQ to issue a health alert for 150 counties. Now, data from this same event are re-analyzed in an attempt to predict air quality from MODIS aerosol optical thickness (AOT) observations. The results demonstrate a method to forecast air quality from remotely sensed satellite observations when the transient pollution can be isolated from local sources. These pollution sources can be separated using TCEQ's network of ground-based Continuous Air quality Monitoring (CAM) stations.

    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.

    2005-01-01

    Several series of cracking tests in a comprehensive study were conducted on separate occasions involving all or parts of ten Canadian vacuum gas oils (VGOs) and two catalysts with bottoms-cracking or octane-barrel capability.VGOs were cracked in fixed- and/or fluid-bed microactivity test (MAT) units, in an Advanced Cracking Evaluation (ACE)unit, and in a modified ARCO riser reactor. Individual yields of gas, liquid, and coke from the MATs at 55, 65, 70, and 81 wt% conversion levels were compared with their respective pilot plant data. Good linear correlations could be established between MAT and riser yields except for liquefied petroleum gas (LPG) and light cycle oil (LCO). At a given conversion,correlations existed among the fixed- and fluid-bed MAT units and the ACE for each product yield. Liquid products from the fixed or fluid-bed MAT were analyzed for hydrocarbon types, sulfur, nitrogen and density, most of which showed good agreement with those obtained from the riser study. When cracking Canadian oil-sands-derived VGOs, the bottomscracking catalyst containing a large-pore active matrix was found to be more suitable than the octane-barrel catalyst with smaller pores to produce higher yields of valuable distillates, but with less superior qualities (in terms of sulfur and nitrogen contents). The advantages of hydrotreating some poor feeds to improve product yields and qualities were demonstrated and discussed.

  1. 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)

    Zhaolin Cheng

    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.

  2. Grassland-Cropping Rotations: An Avenue for Agricultural Diversification to Reconcile High Production with Environmental Quality

    Science.gov (United States)

    Lemaire, Gilles; Gastal, François; Franzluebbers, Alan; Chabbi, Abad

    2015-11-01

    A need to increase agricultural production across the world to ensure continued food security appears to be at odds with the urgency to reduce the negative environmental impacts of intensive agriculture. Around the world, intensification has been associated with massive simplification and uniformity at all levels of organization, i.e., field, farm, landscape, and region. Therefore, we postulate that negative environmental impacts of modern agriculture are due more to production simplification than to inherent characteristics of agricultural productivity. Thus by enhancing diversity within agricultural systems, it should be possible to reconcile high quantity and quality of food production with environmental quality. Intensification of livestock and cropping systems separately within different specialized regions inevitably leads to unacceptable environmental impacts because of the overly uniform land use system in intensive cereal areas and excessive N-P loads in intensive animal areas. The capacity of grassland ecosystems to couple C and N cycles through microbial-soil-plant interactions as a way for mitigating the environmental impacts of intensive arable cropping system was analyzed in different management options: grazing, cutting, and ley duration, in order to minimize trade-offs between production and the environment. We suggest that integrated crop-livestock systems are an appropriate strategy to enhance diversity. Sod-based rotations can temporally and spatially capture the benefits of leys for minimizing environmental impacts, while still maintaining periods and areas of intensive cropping. Long-term experimental results illustrate the potential of such systems to sequester C in soil and to reduce and control N emissions to the atmosphere and hydrosphere.

    Full Text Available A tactical-operational level quantitative model can be an important decision support tool for bioenergy producers. Goal programming approach can help analyze the costs and volume implications of various competing goals in terms of biomass characteristics on part of the bioenergy producers. One cost and six quality characteristics goals, namely moisture and ash contents, and thermal values of two types of biomass (forest harvest residue and un/under-utilized species are selected for the four bioenergy producers in northwestern, Ontario, Canada. We run four models cenarios: i benchmark total cost and ceilings of mean values of six biomass qualities (Initial Goals, iirelaxing the quality goals by 10% from the Initial Goals scenario, iii increasing the conversion efficiency by 10%, and iv all goals as in Initial Goals except the Atikokan Generating Station (AGSbeing supplied with only un/under-utilized biomass. The smaller power plants have relatively less per unit biomass procurement cost. While per unit procurement costs increased, the total costs and biomass volume required to produce the same amount of bioenergy for each power plant decreased in all scenarios compared to the benchmark costs. The goal programming approach, and the results thereof are found to be useful in making effective decisions in the biomass supply chains for bioenergy production.

These requirements are based on the tried and tested standard methods of the German Society of Hygiene and Microbiology (DGHM as well as on European standards. They take account of the different requirements dictated by the various fields of application, reflecting the quality assurance system in a transparent manner. Special emphasis is increasingly placed on retesting the products already available on the market. In multi-center trials the inter- and intralaboratory fluctuations in the test results are ascertained, the quest for suitable standard substances intensified, culture conditions and detection procedures are standardized and the test procedures and potential influence factors analyzed in detail. The aim here is to devise test procedures that will yield a reproducible and reliable result independently of the test location, and meet the requirements of everyday practice. Attention must be paid to, inter alia, the prevailing microbial spectrum in quality and quantity, the prevailing organic and inorganic load as well as material and surface properties.The test procedures are gradually brought into line with the current stock of scientific knowledge, because such a task calls for conscientiousness, tenacity and patience as well as continuous dialog between research, industry and practice. Thanks to these joint efforts, we are increasingly better able to meet the demands made by intelligent and selective prophylactic disinfection.

    The aim of this investigation was to estimate honeys and bee products quality in view of their mineral composition using multivariate techniques. Fourteen elements (Ca, Mg, K, Na, P, Co, Mn, Fe, Cr, Ni, Zn, Cu, Cd, and Pb) were determined in 66 honeys and bee products from different places of Poland and Europe and various botanical origins. The total metals contents were analyzed by flame atomic absorption spectrometry using deuterium-background correction after wet digestion with nitric acid in an automatic microwave digestion system. Phosphorus was determined in the form of phosphomolybdate by a spectrophotometric method. Reliability of the procedure was checked by analysis of the certified reference materials tea (NCS DC 73351) and cabbage (IAEA-359). The analytical data indicated a good level of quality of honeys, especially with regard to the concentration of toxic trace elements, such as Cd and Pb. Results were submitted to multivariate analysis, including such techniques as factor and cluster analyses in order to evaluate the existence of data patterns and the possibility of classification of honeys from different botanical origins according to their mineral content. The nine metals determined were considered as chemical descriptors of each sample. There was a significant influence of the botanical and geographical provenance as well as technological processing on the elemental composition of honeys. PMID:22930187

    Full Text Available In this research variables which influence microbiological quality in fresh cheese productionwith respect to yeasts and moulds were analyzed. Since yeasts and moulds do not survive the process of pasteurization their isolation in the final product is a result of their supplemental contamination during fermentation and whey drainage. Following variables were monitored: total number of aerobicmesophilic bacteria AMB in rinsing water, total number of yeasts and moulds in rinsing water, total number of AMB in pasteurized milk, total number of AMB in air and total number of yeasts and mouldsin air. These variables were analysed by methods of descriptive statistics, principal component analysis, and the method of artificial intelligence - decision tree. By the method of principal component analysis it is shown that the greatest impact on the quality of the final product have variables connected to microbiological cleanness of air. The method of decision tree has resulted in determination of new internal standards for total number of AMB and yeasts and moulds in the air.

    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.

    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.

  20. Statistical process control: An approach to quality assurance in the production of vitrified nuclear waste

    International Nuclear Information System (INIS)

    Current planning for liquid high-level nuclear wastes existing in the United States includes processing in a liquid-fed ceramic melter to incorporate it into a high-quality glass, and placement in a deep geologic repository. The nuclear waste vitrification process requires assurance of a quality product with little or no final inspection. Statistical process control (SPC) is a quantitative approach to one quality assurance aspect of vitrified nuclear waste. This method for monitoring and controlling a process in the presence of uncertainties provides a statistical basis for decisions concerning product quality improvement. Statistical process control is shown to be a feasible and beneficial tool to help the waste glass producers demonstrate that the vitrification process can be controlled sufficiently to produce an acceptable product. This quantitative aspect of quality assurance could be an effective means of establishing confidence in the claims to a quality product

    Science.gov (United States)

    Kroes, Burt H

    2014-12-01

    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

    2014-09-01

    Full Text Available Background: Hospital discharge records are widely classified through the Diagnosis Related Group (DRG system; the version currently used in Italy counts 538 different codes, including thousands of diagnosis and procedures. These numbers reflect the considerable effort of simplification, yet the current classification system is of little use to evaluate hospital production and performance.Methods: As the case-mix of a given Hospital Unit (HU is driven by its physicians’ specializations, a grouping of DRGs into a specialization-driven classification system has been conceived through the analysis of HUs discharging and the ICD-9-CM codes. We propose a three-folded classification, based on the analysis of 1,670,755 Hospital Discharge Cards (HDCs produced by Lombardy Hospitals in 2010; it consists of 32 specializations (e.g. Neurosurgery, 124 sub-specialization (e.g. skull surgery and 337 sub-sub-specialization (e.g. craniotomy.Results: We give a practical application of the three-layered approach, based on the production of a Neurosurgical HU; we observe synthetically the profile of production (1,305 hospital discharges for 79 different DRG codes of 16 different MDC are grouped in few groups of homogeneous DRG codes, a more informative production comparison (through process-specific comparisons, rather than crude or case-mix standardized comparisons and a potentially more adequate production planning (considering the Neurosurgical HUs of the same city, those produce a limited quote of the whole neurosurgical production, because the same activity can be realized by non-Neurosugical HUs.Conclusion: Our work may help to evaluate the hospital production for a rational planning of available resources, blunting information asymmetries between physicians and managers.

    2015-04-01

    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.

    M.Hohmann; S.Pleier

    2005-01-01

    Metal powders of superlative quality, i.e.high cleanliness, rapidly solidified and spherical shape, have seen an increasing demand in the market.The leading technology for the production of such powders is the inert gas atomization of metal alloy melts.To fulfill these requirements, the metal alloy is usually produced in a vacuum induction melting furnace (VIGA = vacuum induction melting/gas atomization) and poured by means of a preheated tundish system into a gas nozzle where the metal stream is disintegrated by a high kinetic energy inert gas jet.The produced micro-droplets solidify in a free fall inside the atomization tower.For special applications, super-clean and ceramic-free metal powders can be produced by using the EIGA (electrode induction melting/gas atomization) melting- and atomizing system.As an alternative to the metal powder route, the sprayforming technology allows to produce semi-finished products in one step.In this case, the metal droplets produced by the highenergy inert gas nozzle system are directly solidified on a substrate, allowing to form billets,rolls and tubes.

    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.

    O'Connor, Thomas F; Yu, Lawrence X; Lee, Sau L

    2016-07-25

    Issues in product quality have produced recalls and caused drug shortages in United States (U.S.) in the past few years. These quality issues were often due to outdated manufacturing technologies and equipment as well as lack of an effective quality management system. To ensure consistent supply of safe, effective and high-quality drug products available to the patients, the U.S. Food and Drug Administration (FDA) supports modernizing pharmaceutical manufacturing for improvements in product quality. Specifically, five new initiatives are proposed here to achieve this goal. They include: (i) advancing regulatory science for pharmaceutical manufacturing; (ii) establishing a public-private institute for pharmaceutical manufacturing innovation; (iii) creating incentives for investment in the technological upgrade of manufacturing processes and facilities; (iv) leveraging external expertise for regulatory quality assessment of emerging technologies; and (v) promoting the international harmonization of approaches for expediting the global adoption of emerging technologies.

    In recent years, the quality of Earth science data has received much attention from several points of view. First, the scientific quality, defined in terms of accuracy, precision, uncertainty, validity and suitability for use (fitness for purpose) in various applications is considered paramount. In addition, the product quality is important as well. Product quality addresses how well the scientific quality is assessed and documented, how complete the metadata and documentation are, etc. Stewardship quality addresses questions such as how well data are being managed and preserved by an archive or repository, how easy it is for users to find, get, understand, trust, and use data, and whether the archive has people who understand the data available to help users. In general, we can refer to all these aspects of quality together as Information Quality. The purpose of this paper is to discuss the context of and ideas for further work on Earth science information quality. Several related prior activities will be discussed such as: QA4EO, ISO Metadata Quality Standards, NOAA CDR Maturity Matrix, NOAA Data Stewardship Maturity Matrix, NCAR Community Contribution Pages, NASA MEaSUREs Product Quality Checklists, and NASA Earth Science Data System Working Groups (ESDSWG) Data Quality Working Group recommendations. The ESIP Information Quality Cluster is proceeding in this context to: identify additional needs for consistently capturing, describing, and conveying quality information through use case studies with broad and diverse applications; establish and provide community-wide guidance on roles and responsibilities of key players and stakeholders including users and management; prototype conveying quality information to users in a consistent and easily understandable manner; establish a baseline of standards and best practices for data quality; and engage data providers, data managers, and data user communities as resources to improve our standards and best practices.

    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.

  12. Analysis of SORS: a computer program for analyzing fission product release from HTGR cores during transient temperature excursions

    International Nuclear Information System (INIS)

    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

  14. Production and characterization of quality gadolinium oxide nanoparticles

    International Nuclear Information System (INIS)

    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 Gd2O3 nanopowders directly from its bulk counterpart using conventional top-down approach. Recently, we have reported production of Gd2O3 nanopowders by first converting bulk Gd2O3 into a nitrate compound and subsequently reduced into a hydroxide product and finally to the oxide product (nanopowder form)

    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.

  19. The sensory quality of irradiated breaded poultry products

    International Nuclear Information System (INIS)

    The colour, odour, flavour and texture of a breaded turkey escalope irradiated at doses of 2 and 4 kGy was assessed using a trained sensory panel. Irradiation did not affect raw appearance but during storage the irradiated breaded products became paler than the control samples. The off odour of the raw irradiated products was stronger than that of the unirradiated samples. Irradiation also affected the odour, flavour and texture of the cooked products. Although the trained panelists were able to detect significant differences between irradiated and unirradiated breaded turkey escalopes, the numerical differences between treatments were often quite small. It is possible that an untrained consumer group would be unable to detect these differences. Further research is needed with consumer groups to establish if irradiated breaded products are acceptable. (author). 10 refs, 3 tabs

  20. Product design on the basis of fuzzy quality function deployment

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    In the implementation of quality function deployment (QFD), the determination of the target values of engineering characteristics is a complex decision process with multiple variables and multiple objectives that should trade off, and optimize all kinds of conflicts and constraints. A fuzzy linear programming model (FLP) is proposed. On the basis of the inherent fuzziness of QFD system, triangular fuzzy numbers are used to represent all the relationships and correlations, and then, the functional relationships between the customer needs and engineering characteristics and the functional correlations among the engineering characteristics are determined with the information in the house of quality (HoQ) fully used. The fuzzy linear programming (FLP) model aims to find the optimal target values of the engineering characteristics to maximize the customer satisfaction. Finally, the proposed method is illustrated by a numerical example.
