    Full Text Available In this work, serial production lines with finished goods buffers operating in the pull regime are considered. The machines are assumed to obey Bernoulli reliability model. The problem of satisfying customers demand is addressed. The level of demand satisfaction is quantified by the due-time performance (DTP, which is defined as the probability to ship to the customer a required number of parts during a fixed time interval. Within this scenario, the definitions of DTP bottlenecks are introduced and a method for their identification is developed.

    Eriksen, Bo

    Research on employee turnover suggests that turnover results in negative organization-level outcomes. This paper provides a firm-level analysis of the impact of the in- and outflows of human resources on productivity and how the presence of organizational slack resources moderates the effects...... moderate this effect so that the negative consequences of employee turnover are less severe for larger, older and capital intensive firms. These moderating variables indicate the presence of slack resources in the firm, and thus that the accumulation of slack reduces the efficiency losses from employee...

    The objective of this study was to estimate productivity-related savings associated with employee participation in health promotion programs. Propensity score weighting and multiple regression techniques were used to estimate savings. These techniques were adjusted for demographic and health status differences between participants who engaged in one or more telephonic health management programs and nonparticipants who were eligible for but did not engage in these programs. Employees who participated in a program and successfully improved their health care or lifestyle showed significant improvements in lost work time. These employees saved an average of $353 per person per year. This reflects about 10.3 hours in additional productive time annually, compared with similar, but nonparticipating employees. Participating in health promotion programs can help improve productivity levels among employees and save money for their employers.

    Full Text Available Purpose: The paper aims to study the relationship of Line Managers’ (LMs Human Resource (HR role and its facets within employee’s Continuous Professional Development (CPD.Design/methodology/approach: A quantitative approach using 100 questionnaires were distributed to line managers in a South East Asia with a response rate of 87%.Findings: Results depict that LMs are actively involved in Strategic Partner, Employee Champion, and Change Agent roles. Study also shows that these three HR roles correlate with employee CPD. LMs’ are neither involved in Administrative Expert role, nor it correlates with employee Continuous Professional Development.Research limitations: Inability of the line managers to be fully involved with the four HR roles constraints the process of line manager deployment of HR roles specifically to employee CPD.Practical implications: Argues that the importance of strategic partner, employee champion, and change agent roles are the most important barrier and enabler of employee CPD, thus indirectly promoting organizational success and productivity.Social implications: Highlights the difficulties of managing organisations by getting the line managers directly involve in the development of employee CPD. Many line managers have to be made and given opportunities to develop their capabilities on this platform. Contends that HR can help an organization to succeed, provided that all line managers understand their roles, work together and take responsibility for their contribution. In addition is the adoption of the HR roles for the smooth delivery of HR functions which aligns with the overall organizational success.Originality/value: Specific HR roles are significant importance to the development of employee CPD within the setting of this South East Asian organization.

  11. Strategic production line synchronisation

    Directory of Open Access Journals (Sweden)

    Hattingh, Teresa

    2016-08-01

    Full Text Available A study was conducted at the sole global producer of suspension struts for a particular vehicle manufacturer. This supplier is currently able to meet customer demand. However, it does so because of a large finished goods and work-in-progress (WIP inventory. The plant operates two production processes that are separated by a large buffer of WIP, which essentially decouples the production processes. This study aimed to reduce this WIP buffer; this would require the processes to become synchronised, bearing in mind that the reliability of delivery should not decrease. A tool that considers time, quality, and machine capacity was developed to assess the impact of line synchronisation on company performance figures. It was found that line synchronisation produced several benefits for the supplier, including batch size reduction, lower inventory levels, and associated shorter lead times. This further allowed the supplier to improve flow in the plant by introducing a pull system. Improved visual oversight could lead to further improved problem-solving and innovation.

    To assess changes in employee productivity impairment observed after the implementation of several Web-based health promotion programs. Health risk assessments and self-report measures of productivity impairment were administered on-line to more than 43,000 participants of Web-based health promotion programs. Reductions in productivity impairment were observed after 1 month of program utilization. Productivity impairment at 90- and 180-day follow-ups also decreased relative to baseline. Improvements in employee health were associated with reductions in employee productivity impairment. The use of Web-based health promotion programs was associated with reductions in productivity impairment and improvements in employee health. After the implementation of Web-based health promotion programs, reductions in productivity impairment may be observed before reductions in direct health care costs.

    Perceptions of work conditions have proven to be important to the well-being of workers. However, customer loyalty, employee retention, revenue, sales, and profit are essential to the success of any business. It is known that these outcomes are correlated with employee attitudes and perceptions of work conditions, but the research into direction of causality has been inconclusive. Using a massive longitudinal database that included 2,178 business units in 10 large organizations, we found evidence supporting the causal impact of employee perceptions on these bottom-line measures; reverse causality of bottom-line measures on employee perceptions existed but was weaker. Managerial actions and practices can impact employee work conditions and employee perceptions of these conditions, thereby improving key outcomes at the organizational level. Perceptions of specific work conditions that engage employees in their work provide practical guidance in how best to manage people to obtain desired results. © The Author(s) 2010.

  18. Effect of online social networking on employee productivity

    2009-02-01

    Full Text Available The popularity of social networking sites is relatively recent and the effect of online social networking (OSN on employee productivity has not received much scholarly attention. The reason most likely lies in the social nature of social networking sites and OSN, which is assumed to have a negative effect on employee productivity and not bear organisational benefit. This reseach investigated recent Internet developments as seen in the social Web and specifically investigated the effect of OSN on employee productivity and what some of the consequences would be if employees were allowed unrestricted access to these networks. The findings concerning the nature of employees' OSN activities, employees' attitude or perceptions with regard to OSN in the workplace and how OSN can contribute or affect the productivity of employees are discussed in this article. Some of the basic misconceptions regarding OSN are highlighted and it is concluded that this technology can be used to increase collaboration between individuals who share a common interest or goal. Increased collaboration will stimulate knowledge sharing between individuals, with the possible effect of increased productivity. However, the risks associated with OSN should be noted, such as loss of privacy, bandwidth and storage consumption, exposure to malware and lower employee productivity.

    Work limitation rates are crucial indicators of the health status of working people. If related to work productivity, work limitation rates may also supply important information about the economic burden of illness. Our objective was to assess the productivity impact of on-the-job work limitations due to employees' physical or mental health problems. Subjects were asked to complete a self-administered survey on the job during 3 consecutive months. Using robust regression analysis, we tested the relationship of objectively-measured work productivity to employee-reported work limitations. We attempted to survey employees of a large firm within 3 different jobs. The survey response rate was 2245 (85.9%). Full survey and productivity data were available for 1827 respondents. Each survey included a validated self-report instrument, the Work Limitations Questionnaire (WLQ). The firm provided objective, employee-level work productivity data. In adjusted regression analyses (n = 1827), employee work productivity (measured as the log of units produced/hour) was significantly associated with 3 dimensions of work limitations: limitations handling the job's time and scheduling demands (P = 0.003), physical job demands (P = 0.001), and output demands (P = 0.006). For every 10% increase in on-the-job work limitations reported on each of the 3 WLQ scales, work productivity declined approximately 4 to 5%. Employee work limitations have a negative impact on work productivity. Employee assessments of their work limitations supply important proxies for the economic burden of health problems.

    2015-08-01

    The overall aim of this explorative study was to investigate the relationship between factors in the psychosocial work environment and work environment-related production loss. Employees at a Swedish university were invited to answer a workplace questionnaire and were selected for this study if they reported having experienced work environment-related problems in the past 7 days (n = 302). A stepwise logistic regression and a modified Poisson regression were used to identify psychosocial work factors associated with work environment-related production loss as well as to identify at what level those factors are associated with production loss. Employees who reported having experienced work environment problems but also fair leadership, good social climate, role clarity and control of decision had significantly lower levels of production loss, whereas employees who reported inequality and high decision demands reported significantly higher levels of production loss. Never or seldom experiencing fair leadership, role clarity, equality, decision demands and good social climate increase the risk of production loss due to work environment problems, compared to those who experience these circumstances frequently, always or most of the time. Several psychosocial work factors are identified as factors associated with a reduced risk of production losses among employees despite the nature of the work environment problem. Knowledge of these factors may be important not only to reduce employee ill-health and the corresponding health-related production loss, but also reduce immediate production loss due to work environment-related problems.

    Full Text Available A government organisation in the water supply business was faced with the challenge of changing their traditional way of doing business to operate as a profit driven entity. This research focuses on how privatisation has affected front-line service employees. Both the front-line service employees and management were interviewed and included as cases to investigate changes that have occurred as a result of privatisation. These cases revealed that after privatisation front line service employees have received better training, appreciated a better system of communication, experienced a higher degree of empowerment and enjoyed an organisational culture that is more customer focused. The research, however, indicated lower levels of motivation, that employees do not appreciate an improvement in their reward system neither do they get feedback regarding their achievements and that they experience little job security.

    2015-01-01

    Full Text Available This study was conducted to examine the probable effect of perceived empowerment on job performance and the sample of research consisted of 230 participants working in tourism sector as front-line employees. The outcomes of this study indicated that psychological empowerment was positively correlated with employee job performance and employees’ job performance were mostly effected from self-determination and impact dimensions of empowerment. Moreover, tests were conducted to analyze the significant differences in participants’ perception of empowerment and job performance according to their demographic characteristics. There was a significant difference between perceived empowerment and gender, age and work experience where as there was no significant difference between empowerment and education levels. On the other hand, the relationship between job performance and work experience was supported however no relationship was found between job performance and gender, age and education level of the participants. Trying to find out what might possibly lead front-line employees to increased job performance, it can be claimed that psychological empowerment still turns out to be a central issue and therefore this research makes useful contributions to the current knowledge by entirely investigating the direct effect of perceived empowerment on employee job performance in hospitality industry where especially front-line employees spend most of their time directly with customers.

    To examine the relationship between perceived workplace health support and employee productivity. A quantitative cross-sectional study. Washington State agencies. A total of 3528 employees from six state agencies were included in this analysis. Perceived workplace health support was assessed by two questions that queried respondents on how often they felt supported by the workplace for healthy living and physical activity. The Work Productivity and Activity Impairment Questionnaire was used to measure health-related absenteeism and presenteeism in the past 7 days. Multivariate linear regression was used to estimate the mean differences in productivity by levels of perceived health support. Most participants were between 45 and 64 years of age and were predominantly non-Hispanic white. Presenteeism varied significantly by the level of perceived workplace health support, with those who felt least supported having higher presenteeism than those who felt most supported. The difference in presenteeism by perceived workplace support remained significant in models adjusting for sociodemographic and health characteristics (mean difference: 7.1% for support for healthy living, 95% confidence interval: 3.7%, 10.4%; 4.3% for support for physical activity, 95% confidence interval: 1.7%, 6.8%). Absenteeism was not associated with perceived workplace health support. Higher perceived workplace health support is independently associated with higher work productivity. Employers may see productivity benefit from wellness programs through improved perceptions of workplace health support.

    In today's transforming world, increased productivity and efficient use of existing facilities are practically beyond a choice and become a necessity. In this line, attention to change and transformation is one of the affecting factors on the growth of productivity in organizations, especially in hospitals. To examine the effect of transformational leadership on the productivity of employees in teaching hospitals affiliated to Iran University of Medical Sciences. This cross-sectional study was conducted on 254 participants from educational and medical centers affiliated to Iran University of Medical Sciences (Tehran, Iran) in 2016. The standard questionnaires of Bass & Avolio and of Hersi & Goldsmith were used to respectively assess transformational leadership and level of productivity. The research assumptions were tested in a significance level of 0.05 by applying descriptive statistics and structural equations modeling (SEM) using SPSS 19 and Amos 24. Results of the fitting indicators of the assessing model after amending includes Chi-square two to degrees of freedom of 2.756, CFI indicator 0.95, IFI indicator 0.92, Root mean square error of approximation (RMSEA) indicator 0.10. These results indicate that the assessing model is well fitting after the amendment. Also, analysis of the model's assumptions and the final model of the research reveals the effect of transformational leadership on employees' productivity with a significance level of 0.83 (p=0.001). This research indicates that the more the leadership and decision-making style in hospitals lean towards transformational mode, the more positive outcomes it brings among employees and the organization due to increased productivity. Therefore, it is essential to pay focused attention to training/educational programs in organizations to create and encourage transformational leadership behaviors which hopefully lead to more productive employees.

    The proponents of lean production have pointed to the positive effects of the work organization on employees in terms of autonomy, enhanced skills and empowerment mainly by their participation into the continuous improvement of work process. But studies that have examined this issue suggest that the increase in autonomy is not sufficient to compensate for increases work intensity. Participatory design has grown extensively in manufacturing since the 1980's under the impulsion of the Scandinavian socio-technical system approach and it's central in the model of lean production performance. Its main objectives are to improve quality, increase productivity and safety through employee's participation to the reduction of non-value added activities, such as defined by lean production. In the line of the studies on participatory design and continuous improvement the present study examines the functioning of work groups, based on the kaizen model, the aim of which was to improve the proportion of "value-added activities" and working conditions, essentially physical constraints. The main results are consistent with the literature and show that accelerated forms of re-conception activities give employees limited room for maneuver to elaborate solutions based on the analysis of the real activity. This study is part of a broader initiative that goes in the direction of continuous improvement of the design process itself so that it integrates the real constraints of work and propose changes bases on work as it actually takes place, beyond pre-established performance goals bases on the reduction of "non added value activities".

    To investigate the association between lifestyle-related health behaviors including sleep and the cluster of physical activity, no tobacco use, fruits and vegetables intake, and alcohol consumption termed the "Optimal Lifestyle Metric" (OLM), and employee productivity. Data were obtained from employee health assessments (N = 18,079). Regression techniques were used to study the association between OLM and employee productivity, sleep and employee productivity, and the interaction of both OLM and sleep on employee productivity. Employees who slept less or more than 7 or 8 hours per night experienced significantly more productivity loss. Employees who adhered to all four OLM behaviors simultaneously experienced less productivity loss compared with those who did not. Adequate sleep and adherence to the OLM cluster of behaviors are associated with significantly less productivity loss.

    Full Text Available The purpose of this study is to determine the factors having impacts on the physical fatigue of employees and to analyse its influence on work on a production line. In order to carry out these objectives, a comprehensive research was conducted in a medium enterprise producing processed fruit and vegetable products. Air temperature and humidity tests, employee survey, production line productivity measurements, and other observations were performed. Large variations in temperature and humidity were observed during the analysed period. Analysing the survey results, attention was paid to the declared length of sleeping of employees after each shift, the time when they feel fatigue and the factors that, according to respondents, have the greatest impact on the work performed. Attempts were made to determine the wellbeing of employees and to indicate the disturbing symptoms. Special attention was paid to the negative phenomena felt by respondents. The main factors affecting the physical fatigue of employees were identified and described. We sought to explain the impacts of physical fatigue on work on the production line. Improvements, which should help to reduce fatigue and improve working conditions, have been proposed. The analysis provided interesting information that could be used in various food manufacturing companies.

    Hilton, Michael F; Scuffham, Paul A; Vecchio, Nerina; Whiteford, Harvey A

    2010-02-01

    In Australia it has been estimated that mental health symptoms result in a loss of $ AU2.7 billion in employee productivity. To date, however, there has been only one study quantifying employee productivity decrements due to mental disorders when treatment-seeking behaviours are considered. The aim of the current paper was to estimate employee work productivity by mental health symptoms while considering different treatment-seeking behaviours. A total of 60 556 full-time employees responded to the World Health Organization Health and Work Performance Questionnaire. This questionnaire is designed to monitor the work productivity of employees for chronic and acute physical and mental health conditions. Contained within the questionnaire is the Kessler 6, a scale measuring psychological distress along with an evaluation of employee treatment-seeking behaviours for depression, anxiety and any other emotional problems. A univariate analysis of variance was performed for employee productivity using the interaction between Kessler 6 severity categories and treatment-seeking behaviours. A total of 9.6% of employees have moderate psychological distress and a further 4.5% have high psychological distress. Increasing psychological distress from low to moderate then to high levels is associated with increasing productivity decrements (6.4%, 9.4% and 20.9% decrements, respectively) for employees in current treatment. Combining the prevalence of Kessler 6 categories with treatment-seeking behaviours, mean 2009 salaries and number of Australian employees in 2009, it is estimated that psychological distress produces an $ AU5.9 billion reduction in Australian employee productivity per annum. The estimated loss of $ AU5.9 billion in employee productivity due to mental health problems is substantially higher than previous estimates. This finding is especially pertinent given the global economic crisis, when psychological distress among employees is likely to be increasing. Effective

  19. The productivity effect of informal employees: The Tshwane tyre-fitting industry as a case study

    Directory of Open Access Journals (Sweden)

    Gerhardus van Zyl

    2011-09-01

    Research purpose: The aim of the article was to estimate the sign and magnitude of productivity spill over effects of informal employees when employee and firm characteristics as well as external factors were considered. Motivation for the study: The researcher thought that empirical research was appropriate because of the belief that, because of low productivity levels in the South African workplace, firms are resorting to greater numbers of informal employees in order to generate positive productivity spill over effects that would improve their levels of competitiveness. Research design, approach and methodology: The researcher constructed real data series on the applicable variables from weekly data that he collected from firms in the sample group over the sample period. He then applied the Nelen, de Grip and Fourage estimation model to determine the sign and magnitude of the spill over effects for the different employee segments. Main findings: The informal employee segment created greater positive productivity spill over effects. This was especially true for older informal employees with longer tenures and lower levels of absenteeism. External factors, like variations in market demand, improved the positive spill over effects that informal employees generated. Practical/managerial implications: Firms might reconsider the composition of their workforce if the informal employee segment consistently generated higher positive productivity spill over effects. Contribution/value-add: The researcher has introduced an estimation procedure that firms can apply to measure the productivity spill over effects of formal and informal employee segments at firm and industry level.

    2015-06-01

    Full Text Available This paper presents the study of a motorcycle frame production line in a particular company in Malaysia. Due to the high demand, the company needs to increase its production by at least 12% compared with current output. In order to improve productivity, the production-floor data was collected and simulated using the discrete event simulation approach. Later, a number of suggestions for improvement were simulated to identify the effect of the suggestions on productivity. In addition, cost analysis was also undertaken to identify the profit margin for a particular period of time for each suggestion. Simulation results indicate that there are three suggestions that are able to fulfill the 12% volume increment. In the short term, the suggestion to hire an assistant line leader will give instant effect to the profit. Meanwhile, for the medium term, Poka-yoke will give higher profit compared with the others, while in the long term, SOP (standard operating procedure implementation will yield a better profit margin. In future, the simulation of a dynamic demand model for this product is suggested to cope with new trends in the market.

    School health programmes in the 21st century could include eight components: 1) health services; 2) health education; 3) healthy physical and psychosocial environments; 4) psychological, counselling, and social services; 5) physical education and other physical activities; 6) healthy food services; and 7) integrated efforts of schools, families, and communities to improve the health of school students and employees. The eighth component of modern school health programmes, health programmes for school employees, is the focus of this article. Health programmes for school employees could be designed to increase the recruitment, retention, and productivity of school employees by partially focusing each of the preceding seven components of the school health programme on improving the health and quality of life of school employees as well as students. Thus, efforts to improve the quality of life, health, and productivity of school employees may be distinct from, but integrated with, efforts to improve the quality of life, health, and education of students. School employee health programmes can improve employee: 1) recruitment; 2) morale; 3) retention; and 4) productivity. They can reduce employee: 5) risk behaviours (e.g., physical inactivity); 6) risk factors (e.g., stress, obesity, high blood pressure); (7) illnesses; 8) work-related injuries; 9) absentee days; 10) worker compensation and disability claims; and 11) health care and health insurance costs. Further, if we hope to improve our schools' performance and raise student achievement levels, developing effective school employee health programmes can increase the likelihood that employees will: 12) serve as healthy role models for students; 13) implement effective school health programmes for students; and 14) present a positive image of the school to the community. If we are to improve the quality of life, health, and productivity of school employees in the 21st century: school administrators, employees, and

    Full Text Available A software product line (SPL represents a family of products in a given application domain. Each SPL is constructed to provide for the derivation of new products by covering a wide range of features in its domain. Nevertheless, over time, some domain features may become obsolete with the apparition of new features while others may become refined. Accordingly, the SPL must be maintained to account for the domain evolution. Such evolution requires a means for managing the impact of changes on the SPL models, including the feature model and design. This paper presents an automated method that analyzes feature model evolution, traces their impact on the SPL design, and offers a set of recommendations to ensure the consistency of both models. The proposed method defines a set of new metrics adapted to SPL evolution to identify the effort needed to maintain the SPL models consistently and with a quality as good as the original models. The method and its tool are illustrated through an example of an SPL in the Text Editing domain. In addition, they are experimentally evaluated in terms of both the quality of the maintained SPL models and the precision of the impact change management.

    2014-03-01

    To compare employee overall well-being to chronic disease status, which has a long-established relationship to productivity, as relative contributors to on-the-job productivity. Data from two annual surveys of three companies were used in longitudinal analyses of well-being as a predictor of productivity level and productivity change among 2629 employees with diabetes or without any chronic conditions. Well-being was the most significant predictor of productivity cross-sectionally in a model that included disease status and demographic characteristics. Longitudinally, changes in well-being contributed to changes in productivity above and beyond what could be explained by the presence of chronic disease or other fixed characteristics. These findings support the use of well-being as the broader framework for understanding, explaining, and improving employee productivity in both the healthy and those with disease.

The data required for this study was gotten through the instrument of questionnaire. One hundred and twenty four (124 copies of questionnaire were administered out of which one hundred and thirteen (113 were retrieved for analysis. Three hypotheses were formulated from the structured research questions. Regression and correlational analysis were used to test the hypotheses through the statistical package for Social Sciences (SPSS 18.0. The result showed that conducive work environment assists MNCs employee to be motivated at work (R2 = 0.546, at P < 0.05 and that provision of infrastructural facilities have a significant relationship on employee satisfaction (0.699, at P < 0.05. The study therefore recommends among others that that organization should see conducive environment and infrastructural development as a way of helping them to continue being in businesses rather than seeing it as a means of luxury to achieve their desires because it has been proven that infrastructural facility development has assisted in enhancing employee satisfaction.

    Many therapeutically relevant natural products are biosynthesized by the action of giant mega-enzyme assembly lines. By leveraging the specificity, promiscuity, and modularity of assembly lines, a variety of strategies has been developed that enables the biosynthesis of modified natural products. This review briefly summarizes recent structural advances related to natural product assembly lines, discusses chemical approaches to probing assembly line structures in the absence of traditional biophysical data, and surveys efforts that harness the inherent or engineered promiscuity of assembly lines for the synthesis of non-natural polyketides and non-ribosomal peptide analogues.

    Investigate employees' underlying motivational regulatory styles toward healthy living and their associations with lifestyle, work style, health, vitality, and productivity. Regression analyses on cross-sectional data from Dutch employees (n = 629), obtained as baseline measurement before a workplace health promotion project. Controlled regulation was not associated with smoking and alcohol use, and negatively associated with physical activity, healthy dietary habits, relaxation, and a balanced work style. Autonomous regulation was positively associated with physical activity, healthy dietary habits, and relaxation, and negatively associated with smoking and alcohol use. Healthy lifestyle and work style were associated with perceived health and vitality, which in turn were associated with employees' productivity (absenteeism and presenteeism). Internalization of the value of health is important to promote a healthy lifestyle and work style among employees, and has meaningful business implications.

    Culture and employee-focused criteria are important factors for the success of any organization. These factors have to be aligned with the productivity initiatives in the organization in order to gear ahead for excellence. Therefore, this article investigated the impact of culture and employee-focused criteria on productivity in Higher Education Institutions (HEIs) in Malaysia using intangible indicators through core values. The hypothesized relationship was tested using Structural Equation Modeling (SEM) with the PLS estimation technique. 429 questionnaires were returned from the target population. The results of the modelling revealed that the PLS estimation confirmed all the hypotheses tested as in the hypothesized model. The results generally support significant relationships between culture values, employee-focused values and productivity-focused values. The study also confirmed the mediating role of employee-focused values for the relationship between culture values and productivity-focused values. In conclusion, the empirically validated results supported the adequacy of the hypothezised model of the impact of culture and employee-focused criteria on productivity in HEI through value-based indicators.

    This study examines the effects of 13 psychological and physical health conditions on work productivity. One hundred fifty-two staff at the headquarters of a Sri Lankan multinational firm completed a questionnaire asking whether they experienced 13 health conditions common in workplaces, and about their related absenteeism and presenteeism. Most respondents (85.5%) reported absenteeism, presenteeism, or both. Among those reporting a health condition, 57.6% reported losing days due to absenteeism, and 69.5% reported losing additional days to presenteeism. Among those caring for a sick adult or child, 57.3% reported losing days due to absenteeism, and 36.5% reported losing additional days due to presenteeism. Overall productivity loss was 10.43 days each year, 3.95% of employee capacity, equating to about Sri Lanka Rupees 8 million (US$54,421) for all headquarters employees. The health conditions' effects on productivity significantly increased employee costs.

    1989-01-01

    This paper examines a production line composed of multiple stages, or cells, which are passed in sequential order to arrive to the final product. Two possible coordination disciplines are considered, namely: the classical tandem arrangement of sequential working centers with input buffer and the kanban scheme, considered the Japanese shop floor realization of the Just-In-Time (JIT) manifacturing approach. The production line is modelled and analysed by means of Stochastic Petri Nets (SPN). Finally an analysis is made of the possibility that the working cells can incur failure/repair cycles perturbing the production flow of the line and thus reduce performance indices.

    To examine the potential risk factors for work-related fatigue (WRF) among workers in modern industries, the authors analyzed the records of need-for-recovery questionnaires and health checkup results for 1545 employees. Compared with regular daytime workers, and after adjusting for confounders, the workers adapting to day-and-night rotating shift work (RSW) had a 4.0-fold (95% confidence interval [CI] = 2.7-5.9) increased risk for WRF, higher than the 2.2-fold risk (95% CI = 1.5-3.3) for persistent shift workers. Based on highest education level, the male employees with university degrees had the highest adjusted odds ratio (a-OR) 2.8 (95% CI = 1.0-7.8) for complaining of WRF versus compulsory education group. For female workers, currently married/cohabiting status was inversely associated with WRF (a-OR = 0.5; 95% CI = 0.2-0.9), and child-rearing responsibility moderately increased WRF risk (a-OR = 1.9; 95% CI = 1.0-3.7). Day-and-night RSW and the adaptation, educational levels of males, and domestic factors for females contributed to WRF among semiconductor manufacturing employees. © 2013 APJPH.

    Full Text Available Summary. The task of exergy analysis - evaluation based on the second law of thermodynamics, thermodynamic degree of technical perfection of the whole system, as well as to identify those stages of a technical process, which contains the bulk of the loss of exergy in order to improve its efficiency. Using exergy analysis allows to solve a wide range of technical problems on the basis of a unified thermodynamic methods. Exergy analysis was performed by the method whereby thermotechnological system candied fruit production, conventionally separated from the environment of the closed control surface. Exchange scheme under consideration thermotechnological candied fruit production material, thermal and energy flows to the environment, as well as between the control surfaces. Exergy in external input material streams: air and water and citric acid, as well as output streams without having increment Shih-exergy in the process of passing through the reference surface - of running air-water and after washing, are in thermodynamic equilibrium with the surroundings is zero. In the total number of internal exergy losses include losses from the final result of the temperature difference in the heat exchange between the raw material to be dried and heated air electromechanical arising from irreversible alteration of structural and mechanical properties of the product, and the hydraulic loss due to the sudden increase of the specific volume of air as it enters the working chamber dryer. The resulting exergy efficiency is 8.87 %, which is 3.7 % higher than when using the technology of the prototype based on solar air-dried product. This indicates an increase in the degree of perfection of the thermodynamic system by using microwave heating of the product in combination with the removal of moisture in the atmosphere low temperature coolant, which precludes significant outside exergy loss on drying step.

    Full Text Available Lean buffering is the smallest buffer capacity necessary to ensure the desired production rate of a manufacturing system. In this paper, analytical methods for selecting lean buffering in serial production lines are developed under the assumption that the machines obey the Bernoulli reliability model. Both closed-form expressions and recursive approaches are investigated. The cases of identical and nonidentical machines are analyzed. Results obtained can be useful for production line designers and production managers to maintain the required production rate with the smallest possible inventories.

One part of the objective was to examine the continuity between applied leadership style of branch managers and their time in control functions held. Dependencies between the individual productiveness of bank sales clerks and the level of their loyalty and satisfaction were investigated. Opinions of branch managers about the applicable leadership style and room for sales clerks’ productiveness improvement were examined through two questionnaire surveys (conducted in 2008 and 2012. The research results confirmed that the directive style of leadership is the mandatory style in the banking sector in Slovakia whereas the intensity of its implementation during the analysis period was increased. The research has also shown that there is a direct connection between the dominant style of leadership and room for improvement of sales clerks’ productiveness, because the growth of the intensity of directive style in this case led to lower productiveness of the average bank sales clerks. Our assumption that the applied leadership style of bank employees depends on timeworking in managerial positions has not been confirmed. In comparison to long-term managers, branch managers who were working for rather short period in any managerial positions did not show any differences in their management priorities. The assumption that the employee satisfaction and loyalty significantly encourage individual employee productiveness was not confirmed in the research.

    2008-08-01

    To expand a study of the impact of overtime on employee health, safety, and productivity outcomes, previously reported in this journal, with tests comparing older versus younger workers on these relationships. Secondary analyses of a longitudinal panel (n = 2746) representing workers at US sites for a heavy manufacturer during 2001 to 2002. Structural equation techniques were used to assess two hypotheses in the context of multiple group models positing the prediction of a broad set of employee outcomes using a three-step causal sequence. One set of models compared overtime impact for three age groups (increases were largely confined to hourly employees working extended overtime (averaging 60+ hours per week) and occurred on only four of the nine study outcomes. With respect to moderate overtime (48.01 to 59.99 hours) and to variables reflecting the possible impact of past overtime (eg, prior disability episodes), increases in age among hourly employees did not lead to stronger associations between overtime and adverse outcomes on most tests and in fact in many cases were linked to decrements in these associations (hypothesis #2). Salaried employees recorded no greater linkages between overtime and adverse outcomes with advancing age across all tests involving hypothesized overtime effects or "possibly a function of overtime" effects. The results support the proposition that, when employees work overtime, adverse outcomes--and indirect costs--do not increase with advancing age in any kind of wholesale fashion. Where rates of adverse outcomes do increase, they are confined to certain subgroups of employees doing certain types of work and occur on certain dimensions at certain levels of longer work hours. It is argued that carefully calibrated approaches vis-à-vis older workers are needed to maximize employer capacity to address the unique challenges posed by this increasingly important portion of the workforce.

    Full Text Available Kraus and Yano (2003 established the share-of-surplus product line optimisation model and developed a heuristic procedure for this nonlinear mixed-integer optimisation model. In their model, price of a product is defined as a continuous decision variable. However, because product line optimisation is a planning process in the early stage of product development, pricing decisions usually are not very precise. In this research, a nonlinear integer programming share-of-surplus product line optimization model that allows the selection of candidate price levels for products is established. The model is further transformed into an equivalent linear mixed-integer optimisation model by applying linearisation techniques. Experimental results in different market scenarios show that the computation time of the transformed model is much less than that of the original model.

  13. Security Requirements Management in Software Product Line Engineering

    Mellado, Daniel; Fernández-Medina, Eduardo; Piattini, Mario

    Security requirements engineering is both a central task and a critical success factor in product line development due to the complexity and extensive nature of product lines. However, most of the current product line practices in requirements engineering do not adequately address security requirements engineering. Therefore, in this chapter we will propose a security requirements engineering process (SREPPLine) driven by security standards and based on a security requirements decision model along with a security variability model to manage the variability of the artefacts related to security requirements. The aim of this approach is to deal with security requirements from the early stages of the product line development in a systematic way, in order to facilitate conformance with the most relevant security standards with regard to the management of security requirements, such as ISO/IEC 27001 and ISO/IEC 15408.

    2004-10-01

    This study examined the loss of productivity and health risk status associated with employees who provide care for an ill dependent. A total of 16,651 employees (23% response rate) of a major financial services company completed a confidential Health Risk Appraisal (HRA) that included an eight-item version of the Work Limitations Questionnaire and a self-report of time missed from work during the previous 2 weeks to care for an ill dependent. A total of 10.6% of the respondents reported an average of 7.7 hours absent from work during the previous 2-week period to provide care for an ill dependent. Caregiving also was associated with a significant increase in the number of health risks for the employee. As the demand for caregiving time increased, caregivers reported a significant increase in work limitations. Caregiving for an ill dependent is associated with increased absenteeism and significant work limitations while on the job. Programs and work organization that helps employees balance their caregiving responsibilities for ill dependents may have a positive effect on health and productivity.

    2013-01-01

    Objective To test whether overweight or obese employees who achieve clinically significant weight loss of 5% or greater have reduced medical expenditures, absenteeism, presenteeism, and/or improved Health-Related Quality Of Life (HRQOL). Methods The sample analyzed combines data from full-time overweight or obese employees who took part in one of the WAY to Health weight loss studies: one that took place in 17 community colleges (935 employees) and another in 12 universities (933), all in North Carolina. The estimations are performed using non-linear difference-in-difference models where groups are identified by whether the employee achieved a 5% or greater weight loss (treated) or not (control) and the treatment variable indicates pre- and post-weight loss intervention. The outcomes analyzed are the average quarterly (90 days) amount of medical claims paid by the health insurer, number of days missed at work during the past month, Stanford Presenteeism Scale SPS-6 and the EQ-5D-3L measure of HRQOL. Results We find statistical evidence supporting that 5% or greater weight loss prevents deterioration in EQ-5D-3L scores by 0.026 points (p-value: 0.03) and reduces both absenteeism by 0.258 days per month (p-value: 0.093) and the likelihood of showing low presenteeism (Stanford SPS-6 score between 7 and 9) by 2.9 percentage points (p-value: 0.083). No reduction in medical expenditures was observed. Conclusions Clinically significant weight loss among overweight or obese employees prevents short term deterioration in HRQOL and there is some evidence that employee productivity is increased. We find no evidence of a quick return on investment from reduced medical expenditures, although this may occur over longer periods. PMID:23632594

    Rosemberg, Marie-Anne S; Li, Yang

    2018-03-01

    This study explored the relationship between effort-reward imbalance (ERI) at work and work productivity among hotel housekeepers. A community-based approach was used to recruit 23 hotel housekeepers who completed the ERI and Work Performance Questionnaires. Work productivity was determined by combining self-report absenteeism and presenteeism. More than 40% of the participants reported high ERI (ERI >1). Also, 59.1% reported low work productivity. Interestingly, despite the individualized high reports of ERI and low work productivity, correlation analysis showed that high ERI was correlated with high presenteeism and work productivity as a whole. This is the first study to explore work productivity among this worker group. Despite the small sample size and the cross-sectional nature of the study, this study points to the need for organization-based interventions to not only improve employee health but also their work productivity.

  19. Recombinant protein production from stable mammalian cell lines and pools.

    Hacker, David L; Balasubramanian, Sowmya

    2016-06-01

    We highlight recent developments for the production of recombinant proteins from suspension-adapted mammalian cell lines. We discuss the generation of stable cell lines using transposons and lentivirus vectors (non-targeted transgene integration) and site-specific recombinases (targeted transgene integration). Each of these methods results in the generation of cell lines with protein yields that are generally superior to those achievable through classical plasmid transfection that depends on the integration of the transfected DNA by non-homologous DNA end-joining. This is the main reason why these techniques can also be used for the generation of stable cell pools, heterogenous populations of recombinant cells generated by gene delivery and genetic selection without resorting to single cell cloning. This allows the time line from gene transfer to protein production to be reduced. Copyright © 2016 Elsevier Ltd. All rights reserved.

    2011-08-01

    Full Text Available PL for SOA proposes, formally, a software engineering methodology, development techniques and support tools for the provision of service product lines. We propose rigorous modeling techniques for the specification and verification of formal notations and languages for service computing with inclinations of variability. Through these cutting-edge technologies, increased levels of flexibility and adaptivity can be achieved. This will involve developing semantics of variability over behavioural models of services. Such tools will assist organizations to plan, optimize and control the quality of software service provision, both at design and at run time by making it possible to develop flexible and cost-effective software systems that support high levels of reuse. We tackle this challenge from two levels. We use feature modeling from product line engineering and, from a services point of view, the orchestration language Orc. We introduce the Smart Grid as the service product line to apply the techniques to.

    2009-01-01

    This paper presents experiences of verifying architectural design rules of the NASA Core Flight Software (CFS) product line implementation. The goal of the verification is to check whether the implementation is consistent with the CFS architectural rules derived from the developer's guide. The results indicate that consistency checking helps a) identifying architecturally significant deviations that were eluded during code reviews, b) clarifying the design rules to the team, and c) assessing the overall implementation quality. Furthermore, it helps connecting business goals to architectural principles, and to the implementation. This paper is the first step in the definition of a method for analyzing and evaluating product line implementations from an architecture-centric perspective.

    2017-09-01

    Full Text Available The aim of this paper is to apply an integrated model, which combines methods of classical and fuzzy Multi-criteria decision making (MCDM in selected six large equity companies from the Serbian energy sector. The data considered are retrieved from the official financial statements. Four main criteria were analyzed, identified by the previous researchers and pointing to the employees productivity: Operating income/Number of employees, Equity/Number of employees, Net income/Number of employees and Total assets/Number of employees. The contribution of this paper lies in the application of a hybrid model that integrates two MCDM methods: Fuzzy Analytic Hierarchy Process (FAHP and Technique for Order Performance by Similarity to Ideal Solution (TOPSIS to analyse the employee productivity in selected D-Electrical power supply companies operating in Serbia. The FAHP is an effective method for mathematical representation of uncertain and imprecise evaluations made by humans, while the TOPSIS method is an efficient way to rank the alternatives. Results show that operating income is of highest importance for estimating employee productivity and decision making, while equity is of the weakest. Furthermore, the most productive operations in large enterprises from selected companies of the sector D-Electrical power supply are found in the company PC EPS Beograd, and the lowest are in the ED Center llc Kragujevac.

    Full Text Available The influence of employees’ challenges on productivity at a provincial department in KwaZulu-Natal has been notably affecting the overall provision of houses and sanitation (service delivery. According to the Annual Performance Plan 2013/14 – 2015/16, the improvement of efficiency and quality of human settlements’ services is one of the strategic goals which focuses on the overall organisational productivity; however, it fails to consider employees’ day-to-day challenges. Thus, the primary purpose of this paper is to investigate challenges at an operational level and determine the impact they have on productivity. Using a quantitative approach, a questionnaire was distributed to a convenience sample of 180 employees within the department. Applying factor analysis, the findings indicate Leadership as having the highest impact while Work-Life Balance displayed the least impact on Organisational Productivity. The results of this study are beneficial to other local, provincial and national public entities.

  15. Bucket Brigades to Increase Productivity in a Luxury Assembly Line

    Directory of Open Access Journals (Sweden)

    Filippo De Carlo

    2013-08-01

    Full Text Available One of the most challenging issues in manual assembly lines is to achieve the best balance of workloads. There are many analytic approaches to solve this problem, but they are often neglected, since they are time-consuming and require high level engineering skills. Fashion bags packaging lines must comply with a number of different products with low production volumes, while the organization of the line is often under the mere responsibility of the foreman, who balances workloads in an empirical way. The aim of this work is to evaluate the effectiveness of the arrangement of bucket brigades (BBs for an assembly line of luxury handbags. To do this, it was decided to perform a testing activity in a company producing fashion handbags in order to compare the self-made design with the BBs and with a simple assembly line balancing problem algorithm. The originality of this research lies in the fact that there are no studies in the literature on BBs applied to the packaging of highly variable small batches. The results were excellent, showing the advantages of BBs in terms of flexibility, the reduction of work in the process and the ability to handle small anomalies.

  16. Aspect-Oriented Model-Driven Software Product Line Engineering

    Science.gov (United States)

    Groher, Iris; Voelter, Markus

    Software product line engineering aims to reduce development time, effort, cost, and complexity by taking advantage of the commonality within a portfolio of similar products. The effectiveness of a software product line approach directly depends on how well feature variability within the portfolio is implemented and managed throughout the development lifecycle, from early analysis through maintenance and evolution. This article presents an approach that facilitates variability implementation, management, and tracing by integrating model-driven and aspect-oriented software development. Features are separated in models and composed of aspect-oriented composition techniques on model level. Model transformations support the transition from problem to solution space models. Aspect-oriented techniques enable the explicit expression and modularization of variability on model, template, and code level. The presented concepts are illustrated with a case study of a home automation system.

    2000-01-01

    Full Text Available The general design problem in serial production lines concerns the allocation of resources such as the number of servers, their service rates, and buffers given production-specific constraints, associated costs, and revenue projections. We describe the design of exPLOre: a modular, object-oriented, production line optimization software architecture. An abstract optimization module can be instantiated using a variety of stochastic optimization methods such as simulated annealing and genetic algorithms. Its search space is constrained by a constraint checker while its search direction is guided by a cost analyser which combines the output of a throughput evaluator with the business model. The throughput evaluator can be instantiated using Markovian, generalised queueing network methods, a decomposition, or an expansion method algorithm.

    Employee empowerment is an important organizational issue. Empowered employees with new ideas and innovative attributes may increase their ability to respond more effectively to face extensive changes in current public health care work environments. The objective of this study was to investigate the relationships between employee empowerment, innovative behaviors and job productivity of public health nurses (PHNs). This study conducted a cross-sectional research design. Purposive sampling was conducted from six health bureaus in northern Taiwan. 670 PHNs were approached and 576 valid questionnaires were collected, with a response rate of 85.9%. Structured questionnaires were used to collect data by post. Meaning and competence subscales of psychological empowerment, information and opportunity subscales of organizational empowerment, and innovative behaviors were the predictors of job productivity, only accounting for 16.4% of the variance. The competence subscale of psychological empowerment made the most contribution to job productivity (beta = 0.31). Meaning subscale of psychological empowerment has a negative impact on job productivity. Employee empowerment and innovative behavior of PHNs have little influence on job productivity. Employees with greater competence for delivering public health showed higher self-evaluated job productivity. The negative influences on job productivity possibly caused by conflict meaning on public health among PHNs in current public health policy. It should be an issue in further researches. Public health department should strengthen continuing education to foster competence of psychological sense of empowerment and innovative behavior to increase job productivity

    Full Text Available In this article old versus new production concepts (NPCs and employment relation instruments, are studied, separately and in combination, to find out which yield high employee performance and low job strain. Therefore, in 2005, TNO conducted coupled surveys among 149 supervisors and employees. In the past decades, in reaction to dysfunctions of Tayloristic and professional bureaucratic production concepts and employment relations, several new forms of employment relations and NPCs, appeared. Examples are the Socio-technical NPC and customized employment relations. In this study both this NPC and customized employment relations - i.c. customized performance targets - demonstrate positive associations with employee performance. According to Socio-technical theory the design of employment relations is relatively unimportant, as human resources are mobilised primarily by the production concept. Our results for this NPC show the legitimacy of this assumption, because its high employee performance is irrespective of the employment relation instruments. On the contrary, in the other NPCs and in professional bureaucracies, the (employment relation instruments of respectively an increased period needed for learning the job, and customized performance targets can compensate for the lower employee performance in these production concepts. The results do not show increased job strain, due to new production concepts, or new employment relations. production concepts, employment relations, labour productivity, socio-technical theory

    The objective of this study was to examine the burden of pain on employee health and productivity at a Fortune 100 company headquartered in the northeastern United States to prioritize target areas for reducing this burden. An electronic survey was conducted in late 2004, which produced a reasonably representative national sample of 1039 active employee respondents. A total of 28.6% of respondents met the study definition for pain. Pain was linked to: 1) drops of more than 45% and 23%, respectively, in Overall Physical and Mental Health; 2) a fivefold increase in health-induced limitations in work performance; and 3) nearly three and two thirds workdays lost to presenteeism and absenteeism over a 4-week period. Afflicted workers displayed considerable room for improvement in their capacity for pain control and management. The prevalence of pain and its impact on those with the condition combine to make it an area of much opportunity for improving workforce health and productivity. Musculoskeletal diseases offer a promising initial target for corporate intervention.

    Evaluate the impact of a multicomponent workplace health promotion program on employee health risks and work productivity. Quasi-experimental 12-month before-after intervention-control study. A multinational corporation headquartered in the United Kingdom. Of 618 employees offered the program, 266 (43%) completed questionnaires before and after the program. A total of 1242 of 2500 (49.7%) of a control population also completed questionnaires 12 months apart. A multicomponent health promotion program incorporating a health risk appraisal questionnaire, access to a tailored health improvement web portal, wellness literature, and seminars and workshops focused upon identified wellness issues. Outcomes were (1) cumulative count of health risk factors and the World Health Organization health and work performance questionnaire measures of (2) workplace absenteeism and (3) work performance. After adjusting for baseline differences, improvements in all three outcomes were significantly greater in the intervention group compared with the control group. Mean excess reductions of 0.45 health risk factors and 0.36 monthly absenteeism days and a mean increase of 0.79 on the work performance scale were observed in the intervention group compared with the control group. The intervention yielded a positive return on investment, even using conservative assumptions about effect size estimation. The results suggest that a well-implemented multicomponent workplace health promotion program can produce sizeable changes in health risks and productivity.

    To study whether knowledge about psychosocial work indicators and a structured method to implement changes based on such knowledge comprise an effective management tool for enhancing organizational as well as employee health and well-being. White- collar employees representing 22 different work units were assessed before and after a 1-year intervention program. Subjective ratings on health and work environment, biologic markers, absenteeism, and productivity were measured. Significant improvements in performance feedback, participatory management, employeeship, skills development, efficiency, leadership, employee well-being, and work-related exhaustion were identified. The restorative hormone testosterone increased during the intervention and changes correlated with increased overall organizational well-being. Absenteeism decreased and productivity improved. Fact-based psychosocial workplace interventions are suggested to be an important process for enhancing employee well-being as well as organizational performance.

    We review the empirical literature that has implemented aspects of our ancestral environment into the workplace and discuss the positive influence these factors have had on employees' physical and psychological health. We focus upon several components of our ancestral environment, including sunlight, greenery, sleep, physical movement, and social interaction with fellow humans as well as animals (specifically, dogs). Employers who are willing to adopt an evolutionary psychological approach to organizing their workplaces may drastically improve their workers' overall physical and psychological health as well as their overall productivity. This will, in turn, decrease employer costs related to medical care, absenteeism, and lack of productivity. Suggestions regarding how to implement these evolutionary psychological methods to the workplace are also discussed.

    Little is known about how sitting time, alone or in combination with markers of physical activity (PA), influences mental well-being and work productivity. Given the need to develop workplace PA interventions that target employees' health related efficiency outcomes; this study examined the associations between self-reported sitting time, PA, mental well-being and work productivity in office employees. Descriptive cross-sectional study. Spanish university office employees (n = 557) completed a survey measuring socio-demographics, total and domain specific (work and travel) self-reported sitting time, PA (International Physical Activity Questionnaire short version), mental well-being (Warwick-Edinburg Mental Well-Being Scale) and work productivity (Work Limitations Questionnaire). Multivariate linear regression analyses determined associations between the main variables adjusted for gender, age, body mass index and occupation. PA levels (low, moderate and high) were introduced into the model to examine interactive associations. Higher volumes of PA were related to higher mental well-being, work productivity and spending less time sitting at work, throughout the working day and travelling during the week, including the weekends (p employees, higher sitting times on work days and occupational sitting were associated with decreased mental well-being (p employees. Employees' PA levels exerts different influences on the associations between sitting time, mental well-being and work productivity. The specific associations and the broad sweep of evidence in the current study suggest that workplace PA strategies to improve the mental well-being and productivity of all employees should focus on reducing sitting time alongside efforts to increase PA.

  11. Potential Errors and Test Assessment in Software Product Line Engineering

    Directory of Open Access Journals (Sweden)

    2015-04-01

    Full Text Available Software product lines (SPL are a method for the development of variant-rich software systems. Compared to non-variable systems, testing SPLs is extensive due to an increasingly amount of possible products. Different approaches exist for testing SPLs, but there is less research for assessing the quality of these tests by means of error detection capability. Such test assessment is based on error injection into correct version of the system under test. However to our knowledge, potential errors in SPL engineering have never been systematically identified before. This article presents an overview over existing paradigms for specifying software product lines and the errors that can occur during the respective specification processes. For assessment of test quality, we leverage mutation testing techniques to SPL engineering and implement the identified errors as mutation operators. This allows us to run existing tests against defective products for the purpose of test assessment. From the results, we draw conclusions about the error-proneness of the surveyed SPL design paradigms and how quality of SPL tests can be improved.

    To evaluate changes in well-being, biometric, and productivity indicators after a well-being intervention. Biometric and self-reported outcomes were assessed among 677 retail distribution center employees before and after a 6-month well-being intervention. Despite lower well-being at baseline compared to an independent random sample of workers, program participants' well-being, productivity, body mass index, systolic blood pressure, and total cholesterol improved significantly after the intervention, whereas the decline in diastolic blood pressure was not significant. Moreover, participants' specific transition across well-being segments over the intervention period demonstrated more improvement than decline. There is evidence that programs designed to improve well-being within a workforce can be used to significantly and positively impact employee health and productivity, which should result in reduced health care costs, improved employee productivity, and increased overall profitability.

    The effects of irradiation on cytokine production in glioma cell lines, NP1, NP2 and NP3, were studied. Culture supernatants were collected after 6, 24, 48 or 72 hours and the concentrations of interleukin (IL)-6 and IL-8 measured by enzyme-linked immunosorbent assay. Spontaneous and IL-1[beta]-stimulated productions were analyzed. Some cells were given a single dose of Lineac irradiation (10 or 20 Gy). Production of IL-6 (with or without IL-1[beta] stimulation) increased gradually to a maximum after 72 hours, more in the 20 Gy-irradiated cells than 10 Gy cells (p<0.01). Production of IL-8 increased gradually to a maximum after 48 or 72 hours. Spontaneous production of IL-8 increased more in 20 Gy-irradiated cells than 10 Gy cells after 6 and 24 hours (p<0.01), but increased more in 10 Gy cells than 20 Gy cells after 48 and 72 hours (p<0.01). The production of IL-8 stimulated by IL-1[beta] increased more in 10 Gy cells than 20 Gy cells 24 hours later (p<0.01). IL-6 and IL-8 production differed in the response to irradiation. Our data suggest that bidirectional communication between the immune system and glioma cells changes after radiotherapy. (author).

    This work is directly related to the SPIRAL project (Systeme de Production d'Ions Radioactifs Acceleres en Ligne) which will start at GANIL at the end of 1998. The aim of the thesis was to study the on line radioactive multicharged ion beam production stages, i.e. the production and diffusion of the radioactive nuclei in a thick target, their possible transfer up to an ECR ion source and their ionisation. Production cross sections of radioactive neutron rich nuclei, formed by fragmentation of a heavy ion beam in a thick target, were measured. An external target-ECR source system, dedicated to the radioactive noble gases production, and two internal target-ECR source systems, dedicated to the radioactive condensable element production, were built and tested on the SIRa tests bench (Separateur d'Ions Radioactifs). Different detection configurations were elaborated in order to identify the radioactive nuclei and estimate their production yields. Finally, a new method for measuring the overall efficiency of the separator was developed and allowed to study the diffusion properties of radioactive noble gases in various targets. (author)

    Shift work is associated with an increased risk of cardiovascular diseases (CVD). Disruption of cortisol production is a potential underlying mechanism. This study explored the associations of diurnal quantity and pattern of cortisol production in relation to (1) current shift work status (exclusive day versus rotating days and nights), (2) years of past shift work and (3) parameters of rotating shift work (timing, length and intensity). Female hospital employees (160 day workers and 168 rotating shift workers) from southeastern Ontario, Canada, participated in a cross-sectional study. Participants completed a baseline questionnaire and measures of body height, weight, and waist circumference were taken. Midstream urine samples were collected over two separate 24-hour periods to measure creatinine-adjusted cortisol. Total diurnal cortisol production and pattern were described with two measures of the area under the curve. The effect of shift work on cortisol was modeled using multivariable linear regression analyses. Cortisol production in day workers and shift workers on their day shift were similar; however, shift workers on the night shift had flatter diurnal cortisol curves and produced less cortisol. This suggests that night work is associated with an acute attenuation of cortisol production.

    In all industries, time losses, which are incurred in processing are very important. As a result, losses are incurred in productivity and cost. This research aimed to reduce lost time that occurs in sauce production line by using the lean six sigma approach. The main objective was to reduce the time for heating sauce which causes a lot of time lost in the production line which affects productivity. The methodology was comprised of the five-phase improvement model of Six Sigma. This approach begins with defining phase, measuring phase, analysing phase, improving phase and controlling phase. Cause-and-effect matrix and failure mode and effect analysis (FMEA) were adopted to screen the factors which affect production time loss. The results showed that the percentage of lost time from heating sauce reduced by 47.76%. This increased productivity to meet the plan.

    Rost, Kathryn; Smith, Jeffrey L.; Dickinson, Miriam

    2005-01-01

    Objective: To test whether an intervention to improve primary care depression management significantly improves productivity at work and absenteeism over 2 years. Setting and Subjects: Twelve community primary care practices recruiting depressed primary care patients identified in a previsit screening. Research Design: Practices were stratified by depression treatment patterns before randomization to enhanced or usual care. After delivering brief training, enhanced care clinicians provided improved depression management over 24 months. The research team evaluated productivity and absenteeism at baseline, 6, 12, 18, and 24 months in 326 patients who reported full-or part-time work at one or more completed waves. Results: Employed patients in the enhanced care condition reported 6.1% greater productivity and 22.8% less absenteeism over 2 years. Consistent with its impact on depression severity and emotional role functioning, intervention effects were more observable in consistently employed subjects where the intervention improved productivity by 8.2% over 2 years at an estimated annual value of $1982 per depressed full-time equivalent and reduced absenteeism by 28.4% or 12.3 days over 2 years at an estimated annual value of $619 per depressed full-time equivalent. Conclusions: This trial, which is the first to our knowledge to demonstrate that improving the quality of care for any chronic disease has positive consequences for productivity and absenteeism, encourages formal cost-benefit research to assess the potential return-on-investment employers of stable workforces can realize from using their purchasing power to encourage better depression treatment for their employees.

    2017-07-01

    Full Text Available With the increasing awareness of sustainability, eco-design has been an important trend in the fashion industry. Many fashion brands such as Nike, Adidas, and The North Face have developed sustainable fashion by incorporating eco-design elements. Eco-design is an important part of sustainable supply chains. In this paper, we conducted a product line analysis of eco-designed products from a famous outdoor sportswear brand, Patagonia. We collected Patagonia’s 2017 Spring Season product line data and analyzed the data through descriptive analysis, factor analysis and correlation analysis. We found that Patagonia mainly uses organic, recycled, and traceable materials in their eco-product line development. We identified that the usage of eco-materials may significantly affect the number of color choices and product weight as well as gender difference, pattern design, product fit and online reviewers’ opinions at Patagonia. We argued that Patagonia should focus on functionality more than aesthetics in eco-design. We discussed how sustainable fashion firms should manage eco-design in the supply chain.

    1995-05-01

    ISP (In-line Strip Production), a continuous process for steel strip production, has recently been set in an italian innovative plant, where ecological impact and power requirements are lighter than usual. This report describes the studies performed by ENEA (Italian Agency for New Technologies, Energy and the Environment), while a prototype reheating facility was arranged by Acciaieria ISP in Cremona (Italy). The authors, after a study of the prototype electromagnetic field, calculate the heating rate, with the thermal network method. Then they detect, with a 1-D-FEM, the heat diffusion through the strip cross section. Afterward, since the heat distribution depends on the eddy current density one, which is given by the magnetic field distribution, the authors, with a 3-D-FEM, carry out a coupled, electromagnetic and thermal, analysis in time domain. The strip temperature map is established by the balance between skin depth heating and surface cooling: a thermal analysis, performed with a moving 2-D-FEM, take into account the effects of the different heating and cooling situations, originated by the strip moving at a speed of 6m/min through four consecutive reheating facilities. The temperatures of a strip sample heated by the prototype have been monitored, acquired by a computer and related with the simulation results. The little difference between experiment and simulation assessed the qualitative and quantitative validity of this analysis, that has come out to be a tool, useful to evaluate the effects of possible improvements to the ISP process

    2017-12-01

    In health economic evaluation studies, to value productivity loss due to absenteeism, existing methods use wages as a proxy value for marginal productivity. This study is the first to test the equality between wage and marginal productivity losses due to absenteeism separately for team workers and non-team workers. Our estimates are based on linked employer-employee data from Canada. Results indicate that team workers are more productive and earn higher wages than non-team workers. However, the productivity gap between these two groups is considerably larger than the wage gap. In small firms, employee absenteeism results in lower productivity and wages, and the marginal productivity loss due to team worker absenteeism is significantly higher than the wage loss. No similar wage-productivity gap exists for large firms. Our findings suggest that productivity loss or gain is most likely to be underestimated when valued according to wages for team workers. The findings help to value the burden of illness-related absenteeism. This is important for economic evaluations that seek to measure the productivity gain or loss of a health care technology or intervention, which in turn can impact policy makers' funding decisions.

    Acute respiratory illnesses (ARI), comprising influenza-like illness (ILI) and other wintertime respiratory illnesses (ORI), impose substantial health and economic burdens on the United States. Little is known about the impact of ILI among household members (HHM), particularly children, on employees' productivity. To quantify the impact of employee and HHM-ILI and ARI on employee productivity, a prospective, observational cohort study was conducted among employees from three large US companies. Employees who had at least one child living at home (N=2013) completed a monthly survey during the 2007-2008 influenza season, reporting the number of days missed from work and hours of presenteeism due to: (1) personal ILI, (2) HHM-ILI, and (3) personal and HHM-ARI. Employee ILI ranged from 4.8% (April) to 13.5% (February). Employees reporting ILI reported more absences than employees not reporting ILI (72% vs 30%, respectively; Pemployees surveyed had at least one child with an ILI; these employees missed more days of work due to HHM illness than employees without an ARI-ill child (0.9 days vs 0.3 days, respectively; PEmployees with ILI were less productive, on average, for 4.8h each day that they worked while sick, 2.5h of which was attributable to ILI. HHM illnesses accounted for 17.7% (1389/7868 days) of employee absenteeism, over half of which was due to HHM-ARI. ILI causes a significant amount of employee absence. Household members, particularly children, comprise a sizable proportion of general illness and injury-related employee absences. Copyright 2010 Elsevier Ltd. All rights reserved.

    Adverse health and productivity outcomes have imposed a considerable economic burden on employers. To facilitate optimal worksite intervention designs tailored to differing employee risk levels, the authors established cutoff points for an Individual Well-Being Score (IWBS) based on a global measure of well-being. Cross-sectional associations between IWBS and adverse health and productivity outcomes, including high health care cost, emergency room visits, short-term disability days, absenteeism, presenteeism, low job performance ratings, and low intentions to stay with the employer, were studied in a sample of 11,702 employees from a large employer. Receiver operating characteristics curves were evaluated to detect a single optimal cutoff value of IWBS for predicting 2 or more adverse outcomes. More granular segmentation was achieved by computing relative risks of each adverse outcome from logistic regressions accounting for sociodemographic characteristics. Results showed strong and significant nonlinear associations between IWBS and health and productivity outcomes. An IWBS of 75 was found to be the optimal single cutoff point to discriminate 2 or more adverse outcomes. Logistic regression models found abrupt reductions of relative risk also clustered at IWBS cutoffs of 53, 66, and 88, in addition to 75, which segmented employees into high, high-medium, medium, low-medium, and low risk groups. To determine validity and generalizability, cutoff values were applied in a smaller employee population (N=1853) and confirmed significant differences between risk groups across health and productivity outcomes. The reported segmentation of IWBS into discrete cohorts based on risk of adverse health and productivity outcomes should facilitate well-being comparisons and worksite interventions.

    López-Ruiz, J. C.; Heradio, Rubén; Cerrada Somolinos, José Antonio; Coz Fernandez, José Ramón; López Ramos, Pablo

    2008-07-01

    This article presents a case study on developing a software product line for data acquisition systems in astronomy based on the Exemplar Driven Development methodology and the Exemplar Flexibilization Language tool. The main strategies to build the software product line are based on the domain commonality and variability, the incremental scope and the use of existing artifacts. It consists on a lean methodology with little impact on the organization, suitable for small projects, which reduces product line start-up time. Software Product Lines focuses on creating a family of products instead of individual products. This approach has spectacular benefits on reducing the time to market, maintaining the know-how, reducing the development costs and increasing the quality of new products. The maintenance of the products is also enhanced since all the data acquisition systems share the same product line architecture.

    This paper presents a new approach to estimating the indirect costs of health-related absenteeism. Productivity losses related to employee absenteeism have negative business implications for employers and these losses effectively deprive the business of an expected level of employee labor. The approach herein quantifies absenteeism cost using an output per labor hour-based method and extends employer-level results to the region. This new approach was applied to the employed population of 3 health insurance carriers. The economic cost of absenteeism was estimated to be $6.8 million, $0.8 million, and $0.7 million on average for the 3 employers; regional losses were roughly twice the magnitude of employer-specific losses. The new approach suggests that costs related to absenteeism for high output per labor hour industries exceed similar estimates derived from application of the human capital approach. The materially higher costs under the new approach emphasize the importance of accurately estimating productivity losses.

    2014-10-01

    Solving equipment selection and line balancing problems together allows better line configurations to be reached and avoids local optimal solutions. This article considers jointly these two decision problems for mass production lines with serial-parallel workplaces. This study was motivated by the design of production lines based on machines with rotary or mobile tables. Nevertheless, the results are more general and can be applied to assembly and production lines with similar structures. The designers' objectives and the constraints are studied in order to suggest a relevant mathematical model and an efficient optimization approach to solve it. A real case study is used to validate the model and the developed approach.

    2000-10-01

    This study describes a proactive in-house program for managing short-term disability (STD) in the workforce of a very large banking system. The goals of this program were to (1) minimize the personal and economic impacts of STD by early intervention, (2) validate the extent and duration of STD, and (3) coordinate medical services and provide guidance to managers that would facilitate an early return to work. This program was made possible by the installation of a comprehensive database, called Occupational Medicine and Nursing Information System. This database mainly includes employees' claims for inpatient and outpatient health services, disability and workers' compensation benefits, wellness program participation, medical examinations and laboratory tests, use of prescription drugs, and results of Health Risk Appraisals. As a result of these efforts, STD event duration declined after this STD management program was implemented in locations heretofore outside the system, and by providing full pay for part-time work after STD, within the system as well. Of note, the average number of STD days per employee showed substantial variation by health plan, including the fact that it was higher (3.9 STD days/employee) for health maintenance organization participants than for indemnity plan members (2.7 STD days/employee).

    This research aims to improve the productivity in the rubber line of a medium-sized industry by increasing the production capacities through the use of the Aggregate Production Planning model. For this purpose an analysis of the production processes of the line was made and the aggregate plan was defined evaluating two strategies: Exact Production Plan (Zero Inventory) and Constant Workforce Plan (Vary Inventory) by studying the costs of both inventory maintenance and workforce. It was also determined how the installed capacity was used with the standards of the rubber line and measures for decreasing production costs were proposed. It was proven that only 70% of the plant capacity was being used so it could be possible to produce more units and to obtain a bigger market for the products of this line.+

    To investigate how worksite health interventions involving a 2.5-hour reduction of weekly working hours with (PE) or without (RWH) mandatory physical exercise affects productivity. Six workplaces in dental health care were matched and randomized to three conditions (PE, RWH and referents). Employees' (N = 177) self-rated productivity and the workplaces' production levels (number of patients) were examined longitudinally. Number of treated patients increased in all conditions during the intervention year. While RWH showed the largest increase in this measure, PE showed significant increases in self-rated productivity, that is, increased quantity of work and work-ability and decreased sickness absence. A reduction in work hours may be used for health promotion activities with sustained or improved production levels, suggesting an increased productivity since the same, or higher, production level can be achieved with lesser resources.

    Ventilation system inside production line for electronic component production needs to meet the factory standard. Because it can eliminate small particles which may cause of human or machine in production as well as it can distribute the circulating air temperature uniformly. CFD is used in this research in order to study the feasibility and plan for machine layout in production line before actual installation. The simulation shows the airflow in every area inside production line. From simulation with releasing the particles from human and machine is found that this ventilation system generates airflow that makes most particles float out of the machines and no particle downs to the conveyor, it results to contamination. In addition, the simulation also shows the range of 19-26 °C air temperature that meets the factory standard. The results of this research are the parts of the data to renovate the production line to get more efficiency and proper on the production.

    2006-05-01

    An inhouse disability management program was implemented to reduce nonoccupational absences in a petrochemical corporation. The program was administered by full-time certified, corporate-based case managers and nine manufacturing location nurses. Employees were required to report all absences on the first day and again on the fourth workday of absence. A medical certification form was required for absences of 4 or more working days. Extended absences were actively managed. An Internet-based case management tool, Medgate, was used as a primary management tool. Results were compared with the previous year among the target population and with company business units not participating in the program. The program resulted in a 10% reduction in total absence days per employee (6.9 to 6.2) compared with the previous year, whereas business units not using the program had an 8% increase (5.5 to 5.9). This disability management program resulted in a more than four to one return on investment based on direct expenditures and cost savings in terms of reduced absence days. The inhouse disability management program was successful by absence duration, employee satisfaction, and return on investment criteria.

    International Nuclear Information System (INIS)

    2013-08-01

    The Underground Openings Line Production Line report describes the design requirements, the design principles, the methods of construction and the target properties for the underground rooms required for the final repository. It is one of five Production Line reports, namely the: Underground Openings Line report, Canister report, Buffer report, Backfill report, Closure report. Together, these reports cover the lifespan of the underground phases of the final repository from the start of construction of the underground rooms to their closure. Posiva has developed reference methods for constructing the underground rooms. Tunnels will be constructed using the drill and blast technique, shafts will be constructed using raise boring and the deposition holes will be constructed by reverse down reaming. Underground openings will be made safe by reinforcement by using rock bolts, net or shotcrete, depending on which type of opening is being considered, and groundwater inflows will be limited by grouting. Posiva's requirements management system (VAHA) sets out the specifications for the enactment of the disposal concept at Olkiluoto under five Levels - 1 to 5, from the most generic to the most specific. In this report, the focus is on Level 4 and 5 requirements, which provide practical guidance for the construction of the underground openings. The design requirements are presented in Level 4 and the design specification in Level 5 In addition to the long-term safety-related requirements included in VAHA, there are additional requirements regarding the operation of underground openings, e.g. space requirements due to the equipment used and its maintenance, operational and fire safety. The current reference design for the disposal facility is presented based on the design requirements and design specifications. During the lifespan of the repository the reference design will be revised and updated according to the design principles as new information is available. Reference

    2004-01-01

    Full Text Available In this study, the buffer allocation problem (BAP in homogeneous, asymptotically reliable serial production lines is considered. A known aggregation method, given by Lim, Meerkov, and Top (1990, for the performance evaluation (i.e., estimation of throughput of this type of production lines when the buffer allocation is known, is used as an evaluative method in conjunction with a newly developed dynamic programming (DP algorithm for the BAP. The proposed algorithm is applied to production lines where the number of machines is varying from four up to a hundred machines. The proposed algorithm is fast because it reduces the volume of computations by rejecting allocations that do not lead to maximization of the line's throughput. Numerical results are also given for large production lines.

    Full Text Available The perception of elements in a system often creates their interdependence, interconditionality, and suppression. The lines from a basic geometrical element have become the model of a reductive world based on isolation according to certain criteria such as function, structure, and social organization. Their traces are experienced in the contemporary world as fragments or ruins of a system of domination of an assumed hierarchical unity. How can one release oneself from such dependence or determinism? How can the lines become less “systematic” and forms more autonomous, and less reductive? How is a form released from modernistic determinism on the new controversial ground? How can these elements or forms of representation become forms of action in the present complex world? In this paper, the meaning of lines through the ideas of Le Corbusier, Leonidov, Picasso, and Hitchcock is presented. Spatial research was made through a series of examples arising from the projects of the architectural studio “Residential Transformations”, which was a backbone for mapping the possibilities ranging from playfulness to exactness, as tactics of transformation in the different contexts of the contemporary world.

    The costs of gastroesophageal reflux disease have not been assessed in Asia, even though the prevalence of gastroesophageal reflux disease is gradually increasing. We evaluated work presenteeism and absenteeism as indirect costs of gastroesophageal reflux disease in Korea. This was a cross-sectional and multicentre study using patient-reported outcome instruments. A total of 1009 full-time employees who visited the gastrointestinal department for any reason (281 patients with gastroesophageal reflux disease and 728 controls) were included. Main outcomes were presenteeism and absenteeism measured as work productivity loss and monetary cost per week. Absenteeism and presenteeism were significantly higher in the gastroesophageal reflux disease than the control group (1.49% vs. 0.46%, P=0.0010; 34.13% vs. 9.23%, Pgastroesophageal reflux disease than the control group (33.09% vs. 9.02%; Pgastroesophageal reflux disease group compared with the control group. Assuming average hourly wages of $14.12, the weekly burden of gastroesophageal reflux disease reached $165.07 per person. Gastroesophageal reflux disease was associated with substantial work productivity loss, mainly due to presenteeism rather than absenteeism, in Korean full-time employees.

  1. Information logistics: A production-line approach to information services

    Science.gov (United States)

    Adams, Dennis; Lee, Chee-Seng

    1991-01-01

    Logistics can be defined as the process of strategically managing the acquisition, movement, and storage of materials, parts, and finished inventory (and the related information flow) through the organization and its marketing channels in a cost effective manner. It is concerned with delivering the right product to the right customer in the right place at the right time. The logistics function is composed of inventory management, facilities management, communications unitization, transportation, materials management, and production scheduling. The relationship between logistics and information systems is clear. Systems such as Electronic Data Interchange (EDI), Point of Sale (POS) systems, and Just in Time (JIT) inventory management systems are important elements in the management of product development and delivery. With improved access to market demand figures, logisticians can decrease inventory sizes and better service customer demand. However, without accurate, timely information, little, if any, of this would be feasible in today's global markets. Information systems specialists can learn from logisticians. In a manner similar to logistics management, information logistics is concerned with the delivery of the right data, to the ring customer, at the right time. As such, information systems are integral components of the information logistics system charged with providing customers with accurate, timely, cost-effective, and useful information. Information logistics is a management style and is composed of elements similar to those associated with the traditional logistics activity: inventory management (data resource management), facilities management (distributed, centralized and decentralized information systems), communications (participative design and joint application development methodologies), unitization (input/output system design, i.e., packaging or formatting of the information), transportations (voice, data, image, and video communication systems

    To evaluate relationships between modifiable health risks and costs and measure potential cost savings from risk reduction programs. Health risk information from active Pepsi Bottling Group employees who completed health risk assessments between 2004 and 2006 (N = 11,217) were linked to medical care, workers' compensation, and short-term disability cost data. Ten health risks were examined. Multivariate analyses were performed to estimate costs associated with having high risk, holding demographics, and other risks constant. Potential savings from risk reduction were estimated. High risk for weight, blood pressure, glucose, and cholesterol had the greatest impact on total costs. A one-percentage point annual reduction in the health risks assessed would yield annual per capita savings of $83.02 to $103.39. Targeted programs that address modifiable health risks are expected to produce substantial cost reductions in multiple benefit categories.

    2009-01-01

    In this study, we describe the classification methodology over a 2-year period of the primary failure modes in categories based on failure data of bread production line. We estimate the probabilities of these categories applying the chi-square goodness of fit test, and we calculate their joint probabilities of mass function at workstation and line level. Then, we present numerical examples in order to predict the causes and frequencies of breakdowns for workstations and for the entire bread production line that will occur in the future. The methodology is meant to guide bread and bakery product manufacturers, improving the operation of the production lines. It can also be a useful tool to maintenance engineers, who wish to analyze and improve the reliability and efficiency of the manufacturing systems

  8. Parameters Investigation of Mathematical Model of Productivity for Automated Line with Availability by DMAIC Methodology

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available Automated line is widely applied in industry especially for mass production with less variety product. Productivity is one of the important criteria in automated line as well as industry which directly present the outputs and profits. Forecast of productivity in industry accurately in order to achieve the customer demand and the forecast result is calculated by using mathematical model. Mathematical model of productivity with availability for automated line has been introduced to express the productivity in terms of single level of reliability for stations and mechanisms. Since this mathematical model of productivity with availability cannot achieve close enough productivity compared to actual one due to lack of parameters consideration, the enhancement of mathematical model is required to consider and add the loss parameters that is not considered in current model. This paper presents the investigation parameters of productivity losses investigated by using DMAIC (Define, Measure, Analyze, Improve, and Control concept and PACE Prioritization Matrix (Priority, Action, Consider, and Eliminate. The investigated parameters are important for further improvement of mathematical model of productivity with availability to develop robust mathematical model of productivity in automated line.

    Brief intervention (BI) research has traditionally examined alcohol and drug use outcomes; however it is unknown whether BIs can also impact on-the-job productivity. This exploratory study examines changes in workplace productivity and related costs for clients receiving a BI for at-risk drinking in the employee assistance program (EAP). Participants were 44 clients attending the EAP for behavioral health concerns, screened for at-risk drinking, assigned to BI+Usual Care (n=25) or UC alone (n=19), and who completed 3-month follow-up. Absenteeism, presenteeism, and productivity costs were derived as outcomes. At follow-up, participants in the BI+UC group had improved productivity when at work (presenteeism) compared to the UC group. The estimated cost savings from improved productivity for the BI+UC group was $1200 per client over the UC group. Groups did not differ by absenteeism (missed days of work). Preliminary evidence suggests the broad impact BIs may have. Implications for future BI research are discussed. PMID:19897312

    Coppa, R.C.; Martin, H.R.

    1987-01-01

    The production of the uranium dioxide (UO 2 ) is carried out at the Cordoba factory, of the Argentine National Atomic Energy Commission, by the uranil carbonate method (AUC). The commercial uranium concentrates (yellow cake) is dissolved with HNO 3 and purificated with tributil phosphate (TBP). The pure uranium compound coming from the reextraction, is concentrated to 0.4 Kg U/l, then the precipitation with CO 2 and NH 3 gives the AUC crystalls. After conversion of AUC to UO 2 powder, the pellets are obtained by direct compacting. In the second experimental method used by CNEA, the yellow cake is dissolved with H 2 SO 4 , and then it is purified with a terciary amine and precipitated with (NH 4 ) 2 CO 3 . In this form the ammonium uranil tri-carbonate (AUT) crystals are obtained. The convertion to UO 2 is made under an atmosphere of dissociated NH 3 . (M.E.L.) [es

    Under normal operating conditions, the monitoring of the possible deterioration of the pressurized water reactor core fuel rods is achieved through analysis of the radioactive fission products carried by the primary system. For acquiring results of spectrometric analyses in real time, and avoiding risks of errors linked to manual operations, CEA/DMG and EDF/SEPTEN have jointly developed an entirely automatic system. This system allows measuring permanently the primary system activity of two coupled units, with no human operation nor any handling of active coolant specimens. The PIGAL facility has been set up in the nuclear auxiliary building, common to the two units, and it is used on a demonstration basis for units 2 and 3 of the BUGEY site. This device has been patented

  17. Product-line selection and pricing with remanufacturing under availability constraints

    Aras, Necati; Esenduran, G.÷k.‡e.; Altinel, I. Kuban

    2004-12-01

    Product line selection and pricing are two crucial decisions for the profitability of a manufacturing firm. Remanufacturing, on the other hand, may be a profitable strategy that captures the remaining value in used products. In this paper we develop a mixed-integer nonlinear programming model form the perspective of an original equipment manufacturer (OEM). The objective of the OEM is to select products to manufacture and remanufacture among a set of given alternatives and simultaneously determine their prices so as to maximize its profit. It is assumed that the probability a customer selects a product is proportional to its utility and inversely proportional to its price. The utility of a product is an increasing function of its perceived quality. In our base model, products are discriminated by their unit production costs and utilities. We also analyze a case where remanufacturing is limited by the available quantity of collected remanufacturable products. We show that the resulting problem is decomposed into the pricing and product line selection subproblems. Pricing problem is solved by a variant of the simplex search procedure which can also handle constraints, while complete enumeration and a genetic algorithm are used for the solution of the product line selection problem. A number of experiments are carried out to identify conditions under which it is economically viable for the firm to sell remanufactured products. We also determine the optimal utility and unit production cost values of a remanufactured product, which maximizes the total profit of the OEM.

Thus the content provider can possibly sell bundles of the product forms, leading to additional revenue. We first ...

  20. LHC dipole magnets start to roll off the production line

    CERN Multimedia

    2000-01-01

    The first pre-series LHC dipole magnet has been delivered to CERN, a further 1247 are due to be produced by 2005. Their production is the result of technology transfer from CERN to its suppliers. Fifteen metres long, thirty-tonnes in weight, and using several kilometres of superconducting cable, the magnet that has just arrived in hall 181 is a true colossus. It is the first pre-series dipole that will begin service in 2005 in the future Large Hadron Collider, LHC. Delivered by the French Alstom-Jeumont Industrie consortium, it is the first of 1248 magnets that will be manufactured over the coming five years. Needless to say, lavish attention has been devoted to this magnet by the engineers and technicians who accompanied it to CERN from Belfort in north east France. The task of the dipole magnets will be to steer the LHC's proton beams on a circular trajectory around the LHC's 27 kilometre circumference. A magnetic field of 8.33 Tesla is required to guide the protons, accelerated to an energy of 7 TeV, aroun...

  1. Aminobenzoates as building blocks for natural product assembly lines.

    Science.gov (United States)

    Walsh, Christopher T; Haynes, Stuart W; Ames, Brian D

    2012-01-01

    The ortho-, meta-, and para- regioisomers of aminobenzoate are building blocks for a wide range of microbial natural products. Both the ortho-isomer (anthranilate) and PABA derive from the central shikimate pathway metabolite chorismate while the meta-isomer is not available by that route and starts from UDP-3-aminoglucose. PABA is largely funnelled into folate biosynthesis while anthranilate is the scaffold for biosynthetic elaboration into many natural heterocycles, most notably with its role in indole formation for tryptophan biosynthesis. Anthranilate is also converted to benzodiazepinones, fumiquinazolines, quinoxalines, phenoxazines, benzoxazolinates, quinolones, and phenazines, often with redox enzyme participation. The 5-hydroxy form of 3-aminobenzaote is the starter unit for ansa-bridged rifamycins, ansamitocins, and geldanamycins, whereas regioisomers 2-hydroxy, 4-hydroxy and 2,4-dihydroxy-3-aminobenzoate are key components of antimycin, grixazone, and platencin and platensimycin biosynthesis, respectively. The enzymatic mechanisms for generation of the aminobenzoate regioisomers and their subsequent utilization for diverse heterocycle and macrocycle construction are examined.

  2. Simulation of Production Lines in the Education of Engineers: How to Choose the Right Software?

    Rostkowska Marta

    2014-12-01

    Full Text Available The article discusses the problems of modeling and simulation in the design of production lines, mainly from an educator's perspective. Nowadays, there is a wide range of computer programs that can be used to design production lines and to simulate various aspects of their operation. However, the programs being available vary considerably as to their functionality, the approach to production system design, and the visualization tools. Therefore we demonstrate and evaluate in this paper four simulation programs, focusing on the easiness of system design, area of the possible applications in education of engineers, and the limitations imposed by versions dedicated for students. We evaluate three of programs for digital factory simulation on a common, simple assembly task, then demonstrate that these programs may be also used for more specialized simulations in various areas of production, and compare with a specialized program for simulation of robotised production lines and work cells.

    There are many harmful factors that possess a damaging impact on the body of employees at aluminum production. It leads to the development of bronchial asthma (BA), chronic nonobstructive bronchitis (CNB) and chronic obstructive pulmonary disease (COPD). The pathogenesis of these disorders, as well as sensitizing effect offluorine in the aluminum production is not fully understood. The purpose of this work was to study the characteristics of laboratory indices in patients with occupational diseases of the respiratory system. In workers of aluminum production with the diagnosis of occupational diseases of respiratory system (15 patients with a diagnosis of asthma, 30 CNB cases, 20 COPD patients) we evaluated the content of total protein, total cholesterol, high density lipoprotein cholesterol (HDLC), total calcium, phosphorus, ceruloplasmin, hematological indices and performed emigration of leukocytes braking test (TTEEL). Clinical and biochemical profile ofpersons with occupational asthma was characterized by a low level of total calcium and ceruloplasmin, a high concentration of phosphorus in the blood serum and inhibition of leukocyte emigration in the test with sodium fluoride. For aluminum production CNB workers characteristic active proatherogenic process was pronounced by a decrease in the HDLC level and an increase in atherogenic index; higher hematocrit value and concentration of erythrocytes, and more than 50% of cases of sensitization to the presence of sodium fluoride. COPD cases had occupational lower average concentration of hemoglobin in the erythrocyte, total protein in serum, as well as polymorphic variant response to sodium fluoride in the form of a depression and activation of leucocytes emigration.

  6. Supporting Development of Satellite's Guidance Navigation and Control Software: A Product Line Approach

    2000-01-01

    The NASA Goddard Space Flight Center Flight Software Branch (FSB) is developing a Guidance, Navigation, and Control (GNC) Flight Software (FSW) product line. The demand for increasingly more complex flight software in less time while maintaining the same level of quality has motivated us to look for better FSW development strategies. The GNC FSW product line has been planned to address the core GNC FSW functionality very similar on many recent low/near Earth missions in the last ten years. Unfortunately these missions have not accomplished significant drops in development cost since a systematic approach towards reuse has not been adopted. In addition, new demands are continually being placed upon the FSW which means the FSB must become more adept at providing GNC FSW functionality's core so it can accommodate additional requirements. These domain features together with engineering concepts are influencing the specification, description and evaluation of FSW product line. Domain engineering is the foundation for emerging product line software development approaches. A product line is 'A family of products designed to take advantage of their common aspects and predicted variabilities'. In our product line approach, domain engineering includes the engineering activities needed to produce reusable artifacts for a domain. Application engineering refers to developing an application in the domain starting from reusable artifacts. The focus of this paper is regarding the software process, lessons learned and on how the GNC FSW product line manages variability. Existing domain engineering approaches do not enforce any specific notation for domain analysis or commonality and variability analysis. Usually, natural language text is the preferred tool. The advantage is the flexibility and adapt ability of natural language. However, one has to be ready to accept also its well-known drawbacks, such as ambiguity, inconsistency, and contradictions. While most domain analysis

  7. Integrating Theory and Practice: Applying the Quality Improvement Paradigm to Product Line Engineering

    Stark, Michael; Hennessy, Joseph F. (Technical Monitor)

    2002-01-01

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

    Product-line administration is a viable approach for managing medical records services in an environment that demands high quantity and quality service levels. Product-line administration directs medical record department team members to look outside of the department and seek input from the customers it is intended to serve. The feedback received may be alarming at first, as the current state of products usually reveals a true lack of customer input. As the planning, defining, managing, and marketing phases are implemented, the road will not be easy and rewards will be slow to come. Product-line administration does not provide quick fixes, but it does provide long-term problem resolution as products are refined and new products developed to meet customer needs and expectations. In addition to better meeting the needs of the department's external customers, the department's internal customers' needs and expectations will be addressed. The participative management approach will help nurture each team member's creativity. The team members will have the opportunity to reach their full potential while reaping the rewards and benefits of providing products and services that meet the needs and expectations of all department customers. The future of the health care industry promises more changes as the country moves toward some form of prospective payment in the ambulatory setting. Reactive management and the constant struggle to catch up can no longer be accepted as a management approach. It is imperative that the medical record department be viewed as a business with product lines composed of quality products. The planning, defining, managing, and marketing components of product-line administration afford responsiveness to the current situation and the development of quality products that will ensure that medical record departments are prepared for the future.

    IgE is a key effector molecule in atopic diseases; however, the regulation mechanisms of IgE production in IgE B cells remain poorly understood. In the present study, we demonstrate that JSI-124 (cucurbitacin I), a selective STAT3 inhibitor, selectively inhibits production of IgE by a human IgE B cell line, CRL-8033 cells, while does not affect the IgG production by IgG B cell lines. In the aspect of molecular mechanism, we found that Igλ, but not Ighe, gene expression was suppressed by JSI-124. The above effects of JSI-124 were not mediated by affecting cellular proliferation or apoptosis. Furthermore, multiple B cell differentiation-related genes expression was not significantly affected by JSI-124. Taken together, we demonstrate a potential strategy of therapeutically suppressing IgE production without affecting IgG production in atopic patients. - Highlights: • JSI-124 inhibits IgE production in an IgE B cell line, CRL-8033 cells. • JSI-124 does not affect IgG production by IgG B cell lines. • JSI-124 inhibits IgE production mainly by suppressing transcription of Igλ.

    Full Text Available The present conceptual paper is an attempt to provide a Value-Based Business Approach (VBBA to product line software engineering. It argues that Product line software engineering should be seen as a system and considered as a means towards the end of appropriating more and more value for the business firm; contingent upon the fact that it provides value to customer and customer's customers operating its value creating system with agility, speed, economy and innovation; getting governed by the positive sum value creation outlook and guided by value- based management. With our value-based business triad, the product line engineering process can hope to achieve simultaneously value, variety and volume, product differentiation and cost leadership enabling the business firm to land on the virtuous value spiral.

    To examine how line managers experience and manage the return to work process of employees on sick leave due to work-related stress and to identify supportive and inhibiting factors. Semi-structured interviews with 15 line managers who have had employees on sick leave due to work-related stress. The grounded theory approach was employed. Even though managers may accept the overall concept of work-related stress, they focus on personality and individual circumstances when an employee is sick-listed due to work-related stress. The lack of a common understanding of stress creates room for this focus. Line managers experience cross-pressure, discrepancies between strategic and human-relationship perspectives and a lack of organizational support in the return to work process. Organizations should aim to provide support for line managers. Research-based knowledge and guidelines on work-related stress and return to work process are essential, as is the involvement of coworkers. A commonly accepted definition of stress and a systematic risk assessment is also important. Cross-pressure on line managers should be minimized and room for adequate preventive actions should be provided as such an approach could support both the return to work process and the implementation of important interventions in the work environment. Implication for rehabilitation Organizations should aim to provide support for line managers handling the return to work process. Cross-pressure on line managers should be minimized and adequate preventive actions should be provided in relation to the return to work process. Research-based knowledge and guidelines on work-related stress and return to work are essential. A common and formal definition of stress should be emphasized in the workplace.

  1. Advances in Mammalian Cell Line Development Technologies for Recombinant Protein Production

    2013-04-01

    Full Text Available From 2006 to 2011, an average of 15 novel recombinant protein therapeutics have been approved by US Food and Drug Administration (FDA annually. In addition, the expiration of blockbuster biologics has also spurred the emergence of biosimilars. The increasing numbers of innovator biologic products and biosimilars have thus fuelled the demand of production cell lines with high productivity. Currently, mammalian cell line development technologies used by most biopharmaceutical companies are based on either the methotrexate (MTX amplification technology or the glutamine synthetase (GS system. With both systems, the cell clones obtained are highly heterogeneous, as a result of random genome integration by the gene of interest and the gene amplification process. Consequently, large numbers of cell clones have to be screened to identify rare stable high producer cell clones. As such, the cell line development process typically requires 6 to 12 months and is a time, capital and labour intensive process. This article reviews established advances in protein expression and clone screening which are the core technologies in mammalian cell line development. Advancements in these component technologies are vital to improve the speed and efficiency of generating robust and highly productive cell line for large scale production of protein therapeutics.

  2. The relationship of metabolic burden to productivity levels in CHO cell lines.

    2018-03-01

    The growing demand for recombinant therapeutics has driven biotechnologists to develop new production strategies. One such strategy for increasing the expression of heterologous proteins has focused on enhancing cell-specific productivity through environmental perturbations. In this work, the effects of hypothermia, hyperosmolarity, high shear stress, and sodium butyrate treatment on growth and productivity were studied using three (low, medium, and high producing) CHO cell lines that differed in their specific productivities of monoclonal antibody. In all three cell lines, the inhibitory effect of these parameters on proliferation was demonstrated. Additionally, compared to the control, specific productivity was enhanced under all conditions and exhibited a consistent cell line specific pattern, with maximum increases (50-290%) in the low producer, and minimum increases (7-20%) in the high producer. Thus, the high-producing cell line was less responsive to environmental perturbations than the low-producing cell line. We hypothesize that this difference is most likely due to the bottleneck associated with a higher metabolic burden caused by higher antibody expression. Increased recombinant mRNA levels and pyruvate carboxylase activities due to low temperature and hyperosmotic stress were found to be positively associated with the metabolic burden. © 2017 International Union of Biochemistry and Molecular Biology, Inc.

  5. Statistical Methods in Assembly Quality Management of Multi-Element Products on Automatic Rotor Lines

    Science.gov (United States)

    Pries, V. V.; Proskuriakov, N. E.

    2018-04-01

    To control the assembly quality of multi-element mass-produced products on automatic rotor lines, control methods with operational feedback are required. However, due to possible failures in the operation of the devices and systems of automatic rotor line, there is always a real probability of getting defective (incomplete) products into the output process stream. Therefore, a continuous sampling control of the products completeness, based on the use of statistical methods, remains an important element in managing the quality of assembly of multi-element mass products on automatic rotor lines. The feature of continuous sampling control of the multi-element products completeness in the assembly process is its breaking sort, which excludes the possibility of returning component parts after sampling control to the process stream and leads to a decrease in the actual productivity of the assembly equipment. Therefore, the use of statistical procedures for continuous sampling control of the multi-element products completeness when assembled on automatic rotor lines requires the use of such sampling plans that ensure a minimum size of control samples. Comparison of the values of the limit of the average output defect level for the continuous sampling plan (CSP) and for the automated continuous sampling plan (ACSP) shows the possibility of providing lower limit values for the average output defects level using the ACSP-1. Also, the average sample size when using the ACSP-1 plan is less than when using the CSP-1 plan. Thus, the application of statistical methods in the assembly quality management of multi-element products on automatic rotor lines, involving the use of proposed plans and methods for continuous selective control, will allow to automating sampling control procedures and the required level of quality of assembled products while minimizing sample size.

    Integrating power plants on long lines and weak power systems requires some care. To this effect, a study was conducted to determine if severe disturbances could result when a hydraulic production plant is integrated along a very long radial transmission line. Frequency responses were evaluated to identify possible resonant system operating conditions. Many events such as faults, transformer energyzing and line opening were investigated. All power plant synchronous machines were represented including exciter and governor regulators. Impact of dynamic modeling of the load was examined. The study demonstrates that the overall protective strategy implemented will limit worst overvoltage constraints imposed to equipment and load within an acceptable level. (author)

    2014-01-01

    Non-destructive analyzing tools are needed at all stages of thin film photovoltaic (PV) development, and on production lines. In thin film PV, layer thicknesses, micro-structure, composition, layer optical properties, and their uniformity (because each elementary cell is connected electrically in series within a big panel) serve as an important starting point in the evaluation of the performance of the cell or module. An important focus is to express the dielectric functions of each component material in terms of a handful of wavelength independent parameters whose variation can cover all process variants of that material. With the resulting database, spectroscopic ellipsometry coupled with multilayer analysis can be developed for on-line point-by-point mapping and on-line line-by-line imaging. This work tries to review the investigations of different types of PV-layers (anti-reflective coating, transparent-conductive oxide (TCO), multi-diode-structure, absorber and window layers) showing the existing dielectric function databases for the thin film components of CdTe, CuInGaSe 2 , thin Si, and TCO layers. Off-line point-by-point mapping can be effective for characterization of non-uniformities in full scale PV panels in developing labs but it is slow in the on-line mode when only 15 points can be obtained (within 1 min) as a 120 cm long panel moves by the mapping station. In the last years [M. Fried et al., Thin Solid Films 519, 2730 (2011)], instrumentation was developed that provides a line image of spectroscopic ellipsometry (wl = 350–1000 nm) data. Up to now a single 30 point line image can be collected in 10 s over a 15 cm width of PV material. This year we are building a 30 and a 60 cm width expanded beam ellipsometer the speed of which will be increased by 10 ×. Then 1800 points can be mapped in a 1 min traverse of a 60 ∗ 120 cm PV panel or flexible roll-to-roll substrate. - Highlights: • Instrumentation developed provides a line image of

    2002-01-01

    Open Wilson line operators and a generalized star product have been studied extensively in noncommutative gauge theories. We show that they also show up in noncommutative scalar field theories as universal structures. We first point out that the dipole picture of noncommutative geometry provides an intuitive argument for the robustness of the open Wilson lines and generalized star products therein. We calculate the one-loop effective action of noncommutative scalar field theory with a cubic self-interaction and show explicitly that the generalized star products arise in the nonplanar part. It is shown that, at the low-energy, large noncommutativity limit, the nonplanar part is expressible solely in terms of the scalar open Wilson line operator and descendants

    2016-06-01

    Full Text Available When developing new products, it is important for a designer to understand users’ perceptions and develop product form with the corresponding perceptions. In order to establish the mapping between users’ perceptions and product design features effectively, in this study, we presented a regression-based Kansei engineering system based on form feature lines for product form design. First according to the characteristics of design concept representation, product form features–product form feature lines were defined. Second, Kansei words were chosen to describe image perceptions toward product samples. Then, multiple linear regression and support vector regression were used to construct the models, respectively, that predicted users’ image perceptions. Using mobile phones as experimental samples, Kansei prediction models were established based on the front view form feature lines of the samples. From the experimental results, these two predict models were of good adaptability. But in contrast to multiple linear regression, the predict performance of support vector regression model was better, and support vector regression is more suitable for form regression prediction. The results of the case showed that the proposed method provided an effective means for designers to manipulate product features as a whole, and it can optimize Kansei model and improve practical values.

    Full Text Available We show that products of snowflaked Euclidean lines are not minimal for looking down. This question was raised in Fractured fractals and broken dreams, Problem 11.17, by David and Semmes. The proof uses arguments developed by Le Donne, Li and Rajala to prove that the Heisenberg group is not minimal for looking down. By a method of shortcuts, we define a new distance d such that the product of snowflaked Euclidean lines looks down on (RN , d, but not vice versa.

  1. Development of at-line assay to monitor charge variants of MAbs during production.

    One major challenge currently facing the biopharmaceutical industry is to understand how MAb microheterogeneity affects therapeutic efficacy, potency, immunogenicity, and clearance. MAb micro-heterogeneity can result from post-translational modifications such as sialylation, galactosylation, C-terminal lysine cleavage, glycine amidation, and tryptophan oxidation, each of which can generate MAb charge variants; such heterogeneity can affect pharmacokinetics (PK) considerably. Implementation of appropriate on-line quality control strategies may help to regulate bioprocesses, thus enabling more homogenous material with desired post-translational modifications and PK behavior. However, one major restriction to implementation of quality control strategies is the availability of techniques for obtaining on-line or at-line measurements of these attributes. In this work, we describe the development of an at-line assay to separate MAb charge variants in near real-time, which could ultimately be used to implement on-line quality control strategies for MAb production. The assay consists of a 2D-HPLC method with sequential in-line Protein A and WCX-10 HPLC column steps. To perform the 2D-HPLC assay at-line, the two columns steps were integrated into a single method using a novel system configuration that allowed parallel flow over column 1 or column 2 or sequential flow from column 1 to column 2. A bioreactor system was also developed such that media samples could be removed automatically from bioreactor vessels during production and delivered to the 2D-HPLC for analysis. With this at-line HPLC assay, we have demonstrated that MAb microheterogeneity occurs throughout the cell cycle whether the host cell line is grown under different or the same nominal culture conditions. © 2013 American Institute of Chemical Engineers.

    PT. XYZ is a wood processing company which produce semi-finished wood with production system is make to order. In the production process, it can be seen that the production line is not balanced. The imbalance of the production line is caused by the difference in cycle time between work stations. In addition, there are other issues, namely the existence of material flow pattern is irregular so it resulted in the backtracking and displacement distance away. This study aimed to obtain the allocation of work elements to specific work stations and propose an improvement of the production layout based on the result of improvements in the line balancing. The method used in the balancing is Ranked Positional Weight (RPW) or also known as Helgeson Birnie method. While the methods used in the improvement of the layout is the method of Systematic Layout Planning (SLP). By using Ranked Positional Weight (RPW) obtained increase in line efficiency becomes 84,86% and decreased balance delay becomes 15,14%. Repairing the layout using the method of Systematic Layout Planning (SLP) also give good results with a reduction in path length becomes 133,82 meters from 213,09 meters previously or a decrease of 37.2%.

    Bortolheiro, Fernanda P A P; Silva, Marcelo A

    2017-01-01

    Water deficit is one of the major stresses affecting plant growth and productivity worldwide. Plants induce various morphological, physiological, biochemical and molecular changes to adapt to the changing environment. Safflower (Carthamus tinctorius L.), a potential oil producer, is highly adaptable to various environmental conditions, such as lack of rainfall and temperatures. The objective of this work was to study the physiological and production characteristics of six safflower lines in response to water deficit followed by rehydration. The experiment was conducted in a protected environment and consisted of 30 days of water deficit followed by 18 days of rehydration. A differential response in terms of photosynthetic pigments, electrolyte leakage, water potential, relative water content, grain yield, oil content, oil yield and water use efficiency was observed in the six lines under water stress. Lines IMA 04, IMA 10, IMA 14 showed physiological characteristics of drought tolerance, with IMA 14 and IMA 16 being the most productive after water deficit. IMA 02 and IMA 21 lines displayed intermediate characteristics of drought tolerance. It was concluded that the lines responded differently to water deficit stress, showing considerable genetic variation and influence to the environment.

    Tumor-associated fever occurs commonly in acute leukemias and lymphomas. We investigated the capacity for in vitro production of pyrogen by three mouse histiocytic lymphoma cell lines (J-774, PU5-1.8, p 388 D1), one myelomonoyctic line (WEHI-3), and tow lymphoma-derived lines, RAW-8 and R-8. Pyrogen was released spontaneously into the culture medium during growth by all cell lines with macrophage or myeloid characteristics including lysozyme production; R-8 cells, of presumed B-lymphocyte origin, did not produce pyrogen. When injected into mice, the pyrogens gave fever curves typical of endogenous pyrogen, were inactived by heating to 56 degrees C and by pronase digestion, and appeared to be secreted continuously by viable cells. Two pyrogenic molecular species produced by H-774 cells were identified by Sephadex filtration, one of mol wt approximately equal to 30,000, and the other greater than or equal to 60,000. By contrast, three carcinoma cell lines of human origin and SV-40 3T3 mouse fibroblasts did not produce pyrogen in vitro. These results suggest that some malignant cells derived from phagocytic cells of bone marrow origin retain their capacity for pyrogen production, and may spontaneously secrete pyrogen during growth.

  9. Methionine sulfoximine supplementation enhances productivity in GS-CHOK1SV cell lines through glutathione biosynthesis.

    2017-01-01

    In Lonza Biologics' GS Gene Expression System™, recombinant protein-producing GS-CHOK1SV cell lines are generated by transfection with an expression vector encoding both GS and the protein product genes followed by selection in MSX and glutamine-free medium. MSX is required to inhibit endogenous CHOK1SV GS, and in effect create a glutamine auxotrophy in the host that can be complemented by the expression vector encoded GS in selected cell lines. However, MSX is not a specific inhibitor of GS as it also inhibits the activity of GCL (a key enzyme in the glutathione biosynthesis pathway) to a similar extent. Glutathione species (GSH and GSSG) have been shown to provide both oxidizing and reducing equivalents to ER-resident oxidoreductases, raising the possibility that selection for transfectants with increased GCL expression could result in the isolation of GS-CHOKISV cell lines with improved capacity for recombinant protein production. In this study we have begun to address the relationship between MSX supplementation, the amount of intracellular GCL subunit and mAb production from a panel of GS-CHOK1SV cell lines. We then evaluated the influence of reduced GCL activity on batch culture of an industrially relevant mAb-producing GS-CHOK1SV cell line. To the best of our knowledge, this paper describes for the first time the change in expression of GCL subunits and recombinant mAb production in these cell lines with the degree of MSX supplementation in routine subculture. Our data also shows that partial inhibition of GCL activity in medium containing 75 µM MSX increases mAb productivity, and its more specific inhibitor BSO used at a concentration of 80 µM in medium increases the specific rate of mAb production eight-fold and the concentration in harvest medium by two-fold. These findings support a link between the inhibition of glutathione biosynthesis and recombinant protein production in industrially relevant systems and provide a process-driven method for

  11. Effects of extended work shifts and shift work on patient safety, productivity, and employee health.

    Keller, Simone M

    2009-12-01

    It is estimated 1.3 million health care errors occur each year and of those errors 48,000 to 98,000 result in the deaths of patients (Barger et al., 2006). Errors occur for a variety of reasons, including the effects of extended work hours and shift work. The need for around-the-clock staff coverage has resulted in creative ways to maintain quality patient care, keep health care errors or adverse events to a minimum, and still meet the needs of the organization. One way organizations have attempted to alleviate staff shortages is to create extended work shifts. Instead of the standard 8-hour shift, workers are now working 10, 12, 16, or more hours to provide continuous patient care. Although literature does support these staffing patterns, it cannot be denied that shifts beyond the traditional 8 hours increase staff fatigue, health care errors, and adverse events and outcomes and decrease alertness and productivity. This article includes a review of current literature on shift work, the definition of shift work, error rates and adverse outcomes related to shift work, health effects on shift workers, shift work effects on older workers, recommended optimal shift length, positive and negative effects of shift work on the shift worker, hazards associated with driving after extended shifts, and implications for occupational health nurses.

  13. Base Stock Policy in a Join-Type Production Line with Advanced Demand Information

    Science.gov (United States)

    Hiraiwa, Mikihiko; Tsubouchi, Satoshi; Nakade, Koichi

    Production control such as the base stock policy, the kanban policy and the constant work-in-process policy in a serial production line has been studied by many researchers. Production lines, however, usually have fork-type, join-type or network-type figures. In addition, in most previous studies on production control, a finished product is required at the same time as arrival of demand at the system. Demand information is, however, informed before due date in practice. In this paper a join-type (assembly) production line under base stock control with advanced demand information in discrete time is analyzed. The recursive equations for the work-in-process are derived. The heuristic algorithm for finding appropriate base stock levels of all machines at short time is proposed and the effect of advanced demand information is examined by simulation with the proposed algorithm. It is shown that the inventory cost can decreases with little backlogs by using the appropriate amount of demand information and setting appropriate base stock levels.

  14. Modeling of Throughput in Production Lines Using Response Surface Methodology and Artificial Neural Networks

    2018-01-01

    Full Text Available The problem of assigning buffers in a production line to obtain an optimum production rate is a combinatorial problem of type NP-Hard and it is known as Buffer Allocation Problem. It is of great importance for designers of production systems due to the costs involved in terms of space requirements. In this work, the relationship among the number of buffer slots, the number of work stations, and the production rate is studied. Response surface methodology and artificial neural network were used to develop predictive models to find optimal throughput values. 360 production rate values for different number of buffer slots and workstations were used to obtain a fourth-order mathematical model and four hidden layers’ artificial neural network. Both models have a good performance in predicting the throughput, although the artificial neural network model shows a better fit (R=1.0000 against the response surface methodology (R=0.9996. Moreover, the artificial neural network produces better predictions for data not utilized in the models construction. Finally, this study can be used as a guide to forecast the maximum or near maximum throughput of production lines taking into account the buffer size and the number of machines in the line.

    We study a large sample of narrow-line radio galaxies (NLRGs) with extended radio structures. Using 1.4 GHz radio luminosities L {sub 1.4}, narrow optical emission line luminosities L {sub [OIII]} and L{sub H{sub {alpha}}}, as well as black hole masses M {sub BH} derived from stellar velocity dispersions measured from the optical spectra obtained with the Sloan Digital Sky Survey, we find that (1) NLRGs cover about four decades of the Eddington ratio, {lambda} {identical_to} L {sub bol}/L {sub Edd}{proportional_to}L {sub line}/M {sub BH}; (2) L {sub 1.4}/M {sub BH} strongly correlates with {lambda}; and (3) radio loudness, R{identical_to}L{sub 1.4}/L{sub line}, strongly anti-correlates with {lambda}. A very broad range of the Eddington ratio indicates that the parent population of NLRGs includes both radio-loud quasars (RLQs) and broad-line radio galaxies (BLRGs). The correlations they obey and their high jet production efficiencies favor a jet production model which involves the so-called magnetically choked accretion scenario. In this model, production of the jet is dominated by the Blandford-Znajek mechanism, and the magnetic fields in the vicinity of the central black hole are confined by the ram pressure of the accretion flow. Since large net magnetic flux accumulated in central regions of the accretion flow required by the model can take place only via geometrically thick accretion, we speculate that the massive, 'cold' accretion events associated with luminous emission-line active galactic nucleus can be accompanied by an efficient jet production only if preceded by a hot, very sub-Eddington accretion phase.

    Full Text Available Production planning includes push, pull and hybrid production systems that production firms determine their production strategies according to many variables before starting production. The administration of this process requires experience and time. The intensity of rivalry makes this kind of decision processes important, because no firm has the luxury to waste time and to make a wrong decision. In order to solve this problem, research proposes to use integrated decision-making trial and evaluation laboratory (DEMATEL and analytic network process (ANP together which are methods of multi-criteria decision-making models. The process being used to establish which options are found to be most acceptable for operations managers has been demonstrated how applicable it is by using the generated model in automotive industry.

    Stephan Weißleder

    2013-03-01

    Full Text Available Systems tend to become more and more complex. This has a direct impact on system engineering processes. Two of the most important phases in these processes are requirements engineering and quality assurance. Two significant complexity drivers located in these phases are the growing number of product variants that have to be integrated into the requirements engineering and the ever growing effort for manual test design. There are modeling techniques to deal with both complexity drivers like, e.g., feature modeling and model-based test design. Their combination, however, has been seldom the focus of investigation. In this paper, we present two approaches to combine feature modeling and model-based testing as an efficient quality assurance technique for product lines. We present the corresponding difficulties and approaches to overcome them. All explanations are supported by an example of an online shop product line.

    A recent development in criticality accident analysis is the deterministic calculations of the transport of fission products and actinides through the barriers of the physical facility. The knowledge of the redistribution of the materials inside the facility will help determine the reentry and clean-up procedures. The amount of radioactive materials released to the environment is the source term for dispersion calculations. We have used an integrated computer model to determine the release of fission products to the environment from a hypothetical criticality event in a glove box of the metal production line (MPL) at the Lawrence Livermore National Laboratory (LLNL)

    The disclosure encompasses in-line reactive condensation processes via vapor phase esterification of bio-oil to decease reactive species concentration and water content in the oily phase of a two-phase oil, thereby increasing storage stability and heating value. Esterification of the bio-oil vapor occurs via the vapor phase contact and subsequent reaction of organic acids with ethanol during condensation results in the production of water and esters. The pyrolysis oil product can have an increased ester content and an increased stability when compared to a condensed pyrolysis oil product not treated with an atomized alcohol.

    2009-01-01

    Sorghum mutant line Zh-30 is a breeding line developed at the Center for the Application of Isotope and Radiation Technology, BATAN by using mutation techniques. Gamma irradiation with the dose of 300 Gy was used to induce sorghum genetic variation. Through selection processes in several generations, the mutant line Zh-30 was identified to have better agronomic characteristics, better grain quality and higher grain yield than the original variety. Research on modified starch quality of this mutant line was done to identify its potential use in food industry. Functionality of pregelatinized, hydroxypropyl and crosslinked starch of this mutant line (Mutant TexInstant 30) has been studied for its use in high fiber muffin products. Characteristics of high fiber muffins containing 1.50; 3.50 and 5.50% of Mutant Tex-Instant 30 replacement levels to wheat flour were evaluated using both sensory panel and physical test methods. With regard to the sensory parameters, the high fiber muffins containing 1.50 - 5.50 % Mutant Tex-Instant 30 in general were not significantly different compared to the standard reference muffin. Results of physical evaluations showed that all Mutant Tex-Instant 30 containing products retained more moisture during baking than the standard reference. Tenderness of all products decreased at similar rate following 24 and 48 hr of room temperature storage and seven days at freezer temperature.

    Full Text Available Sorghum mutant line Zh-30 is a breeding line developed at the Center for the Application of Isotope and Radiation Technology, BATAN by using mutation techniques. Gamma irradiation with the dose of 300 Gy was used to induce sorghum genetic variation. Through selection processes in several generations, the mutant line Zh-30 was identified to have better agronomic characteristics, better grain quality and higher grain yield than the original variety. Research on modified starch quality of this mutant line was done to identify its potential use in food industry. Functionality of pregelatinized, hydroxypropyl and crosslinked starch of this mutant line (Mutant TexInstant 30 has been studied for its use in high fiber muffin products. Characteristics of high fiber muffins containing 1.50; 3.50 and 5.50% of Mutant Tex-Instant 30 replacement levels to wheat flour were evaluated using both sensory panel and physical test methods. With regard to the sensory parameters, the high fiber muffins containing 1.50 - 5.50 % Mutant Tex-Instant 30 in general were not significantly different compared to the standard reference muffin. Results of physical evaluations showed that all Mutant Tex-Instant 30 containing products retained more moisture during baking than the standard reference.

    Prostate-specific antigen is a 33-KDa serine protease that is produced predominantly by prostate epithelium. However, it has been shown that about 30-40% of female breast tumors produce prostate-specific antigen and its production is associated with the presence of estrogen and progesterone receptors. We have now developed a new tissue culture system to study prostate-specific antigen production in breast cancer and its association with prognostic factors such as progesterone receptor and c-erbB-2. For this purpose we investigated the ability of prostate-specific antigen production in five different cell lines, including two breast cancer cell lines, Sk-Br-3 and MDA-MB-453. The prostate-specific antigen in tissue culture supernatant and cytoplasm of the Sk-Br-3 cell line was detected by western blotting and immunoperoxidase, respectively. Furthermore, we found lower expression of c-erbB-2 in Sk-Br-3 than non-prostate-specific antigen producer breast cancer cell line, MDA-MB-453. Progesterone receptor was expressed by both prostate-specific antigen-positive and -negative cell lines and only the intensity of staining and the number of positive cells in Sk-Br-3 population was higher than MDA-MB-453. According to our findings prostate-specific antigen can be considered as a good prognostic factor in breast cancer and we suggest that these two cell lines are a good in vitro model to study the relationship of different breast cancer prognostic factors and their regulations

  12. The degradation of lining of rotary furnaces in the production of zinc oxide

    2014-06-01

    Full Text Available This paper is closely connected with the complex problem of degradation relating to the refractories of rotary furnace linings in the production of zinc oxide. Zinc oxide can be produced by variety of ways, but the most common method of production which is used in Europe is indirect, i.e. pyrolytic combustion of zinc. This method is also called "French process" of manufacturing ZnO. But this mentioned method of preparation leads to the creation of the enormous amount of zinc slag including chemical complexes of elements Fe, Zn and Al. The mechanism of degradation of the lining leads to slag rests and it is closely connected with the mutual interaction of the aggressive agents with the components of the lining. This process creates a new undesired surface layer which increased the overall thickness of zinc slag. Stuck slag has the influence on rapid degradation of the linings and moreover it also decreases the production quality of ZnO. Analysis results introduced in this paper are significant information for minimizing of degradation of rotary furnaces.

    In order to seek for a radio frequency (RF) eigen-mode of waves in producing a plasma between a pair of long dielectric-covered parallel-plate RF electrodes, this paper analyzed all normal modes propagating along the electrodes by solving Maxwell's equations. The result showed that only an odd surface wave mode will produce the plasma in usual experimental conditions, which will become a basic transmission line theory when use of such long electrodes for on-line mass-production of amorphous silicon solar cells

    Full Text Available The aim of this study was to compare 3 Spanish maternal rabbit lines (A, V and LP in terms of milk production and composition. These lines were founded on different criteria but selected for litter size at weaning. A total of 194 mature does in their third or higher parity were used. The milk yield of does was recorded at 1, 2, 3, 4, 8, 9, 10, 11, 15, 16 and 17 d post-partum (dpp. The milk production traits studied were weekly milk yield (WMY; g/wk and milk conversion ratio (MCR; grams of litter gain per grams of milk suckled during the first 21  dpp. The milk composition traits studied were fat (%, protein  (%, ash (%, lactose (% and total solids (%. The milk samples to be analysed were collected from each doe at 18 dpp. Data were analysed using single trait mixed and fixed models with and without covariates; the covariates were number born alive (NBA and doe weight at kindling (DW. The overall mean of WMY, during the first 3 wk, was 1547±16 g/wk. Milk yields during the different lactation weeks were for line A 872±39, 1503±39 and 1865±39 g for first, second and third lactation weeks, respectively. In line V, the corresponding values were 919±35, 1633±35 and 2004±35  g, and in line LP, they were 1043±36, 1819±36 and 2254±36  g. Means of MCR were 0.41±0.01, 0.41±0.01 and 0.42±0.01 for A, V and LP lines, respectively. Overall means of fat, protein, ash, lactose and total solids (% were 14.62±0.17, 11.10±0.07, 1.89±0.04, 2.67±0.12 and 30.27±0.24, respectively. The differences between lines for milk production traits were significant except for MCR, while the differences between lines for milk composition traits were not significant. NBA had significant effects on all milk yield traits but had no significant effects on milk composition traits. DW only had a significant effect on weekly milk yield. The parity order had no significant effect either for milk production traits or milk composition traits in multiparous does, except

    Software Projects in general tend to get more software reuse and componentization in order to reduce time, cost and new products resources. The need for techniques and tools to organize projects of higher quality in less time is one of the greatest challenges of Software Engineering. The Software Product Line is proposed to organize and systematically assist the development of new products in series at the same domain. In this context, this paper is proposed to apply the Software Product Line approach in Distributed Computing Environments. In projects that involve Distributed Environments, each version of the same product can generate repeatedly the same artifacts in a product that evolves its characteristics; however there is a principal architecture with variations of components. The goal of the proposed approach is to analyze the actual process and propose a new approach to develop new projects reusing the whole architecture, components and documents, starting with a solid base and creating new products focusing in new functionalities. We expect that with the application of this approach give support to the development of projects in Distributed Computing Environment.

    The kidney is a major site for insulin removal and degradation, but the subcellular processes and enzymes involved have not been established. We have examined this process by analyzing insulin degradation products by HPLC. Monoiodoinsulin specifically labeled on either the A14 or B26 tyrosine residue was incubated with a cultured kidney epithelial cell line, and both intracellular and extracellular products were examined on HPLC. The products were then compared with products of known structure generated by hepatocytes and the enzyme insulin protease. Intracellular and extracellular products were different, suggesting two different degradative pathways, as previously shown in liver. The extracellular degradation products eluted from HPLC both before and after sulfitolysis similarly with hepatocyte products and products generated by insulin protease. The intracellular products also eluted identically with hepatocyte products. Based on comparisons with identified products, the kidney cell generates two fragments from the A chain of intact insulin, one with a cleavage at A13-A14 and the other at A14-A15. The B chain of intact insulin is cleaved in a number of different sites, resulting in peptides that elute identically with B chain peptides cleaved at B9-B10, B13-B14, B16-B17, B24-B25, and B25-B26. These similarities with hepatocytes and insulin protease suggest that liver and kidney have similar mechanisms for insulin degradation and that insulin protease or a very similar enzyme is involved in both tissues

    Full Text Available On the one hand, getting advantages of Enterprise Resource Planning (ERP systems largely depends on their capacity to be configured and adapted to fit the customer and domain requirements. On the other hand, product line engineering (PLE is a promising approach for configuring and adapting products by means of configuration and derivation processes. While the literature and industrial experiences show the benefits of PLE methods, techniques and tools, there is still a lack of interest in addressing ERP engineering issues with the product line strategy. Objective: The aim of this paper is to identify and analyze the different ways presented in the literature to improve ERP engineering issues with the methods, techniques and tools provided by PLE. Method: To achieve that objective, we reviewed the literature and analyzed available publications. Results: This literature review analyzes six research papers at the intersection between ERP and PLE. It shows that the product line strategy can indeed be applied for ERP configuration and customization. It further shows the evolving interest on this topic and discusses existing contributions.

    Full Text Available The objective of the study was to explore the appropriate cutting age to produce optimal biomass and good nutrient quality from sorghum mutant lines BMR i.e., PATIR 3.5 M7, PATIR 3.6 M7, and PATIR 3.7 M7, also SAMURAI I (M17. A completely randomized in Split Plot design with 2 factors and 3 replicates was used. The first factor was the type of sorghum (SAMURAI I M17, PATIR 3.5, PATIR 3.6, PATIR 3.7 as the main plot and the second factor was the cutting age (85, 95, 105 as a subplot. Parameters observed were the production of stems, leaves, grains, total biomass production, ash, crude fat, crude fiber, crude protein, NFE, TDN, percentage of DMD, OMD and N-NH3. Data were analyzed by using ANOVA followed by DMRT (Duncan Multiple Range Test. The results showed that there were highly significant interactions (P<0.01 between cutting age and type of sorghum in production of stems, leaves, grains, total biomass production, value of TDN, DMD, OMD, and N-NH3. Increasing cutting age significantly increased the percentage of ash content, crude protein and crude fat. The sorghum type significantly affected crude fat content nonBMR sorghum variety of SAMURAI I (M17 and achieved optimal biomass production and nutrient content at cutting age of 85 d similar to BMR sorghum mutant lines PATIR 3.6 and PATIR 3.5, whereas BMR sorghum mutant lines of PATIR 3.7 achieved optimum production at the age of 95 d of cutting. All types of sorghum varieties was not recommended to be harvested at 105 d. Biomass production increased with the increasing of cutting age, but the nutrient content decreased.

    Variability in primary productivity and fishing pressure can shape the abundance, species composition, and diversity of marine life. Though parasites comprise nearly half of marine species, their responses to these important forces remain little explored. We quantified parasite assemblages at two spatial scales, across a gradient in productivity and fishing pressure that spans six coral islands of the Line Islands archipelago and within the largest Line Island, Kiritimati, which experiences a west-to-east gradient in fishing pressure and upwelling-driven productivity. In the across-islands data set, we found that increasing productivity was correlated with increased parasite abundance overall, but that the effects of productivity differed among parasite groups. Trophically transmitted parasites increased in abundance with increasing productivity, but directly transmitted parasites did not exhibit significant changes. This probably arises because productivity has stronger effects on the abundance of the planktonic crustaceans and herbivorous snails that serve as the intermediate hosts of trophically transmitted parasites than on the higher-trophic level fishes that are the sole hosts of directly transmitted parasites. We also found that specialist parasites increased in response to increasing productivity, while generalists did not, possibly because specialist parasites tend to be more strongly limited by host availability than are generalist parasites. After the effect of productivity was controlled for, fishing was correlated with decreases in the abundance of trophically transmitted parasites, while directly transmitted parasites appeared to track host density; we observed increases in the abundance of parasites using hosts that experienced fishing-driven compensatory increases in abundance. The within-island data set confirmed these patterns for the combined effects of productivity and fishing on parasite abundance, suggesting that our conclusions are robust

  12. Inspection logistics planning for multi-stage production systems with applications to semiconductor fabrication lines

    Science.gov (United States)

    Chen, Kyle Dakai

    Since the market for semiconductor products has become more lucrative and competitive, research into improving yields for semiconductor fabrication lines has lately received a tremendous amount of attention. One of the most critical tasks in achieving such yield improvements is to plan the in-line inspection sampling efficiently so that any potential yield problems can be detected early and eliminated quickly. We formulate a multi-stage inspection planning model based on configurations in actual semiconductor fabrication lines, specifically taking into account both the capacity constraint and the congestion effects at the inspection station. We propose a new mixed First-Come-First-Serve (FCFS) and Last-Come-First-Serve (LCFS) discipline for serving the inspection samples to expedite the detection of potential yield problems. Employing this mixed FCFS and LCFS discipline, we derive approximate expressions for the queueing delays in yield problem detection time and develop near-optimal algorithms to obtain the inspection logistics planning policies. We also investigate the queueing performance with this mixed type of service discipline under different assumptions and configurations. In addition, we conduct numerical tests and generate managerial insights based on input data from actual semiconductor fabrication lines. To the best of our knowledge, this research is novel in developing, for the first time in the literature, near-optimal results for inspection logistics planning in multi-stage production systems with congestion effects explicitly considered.

    A multiple growth factor‐producing tumor cell line (NIM‐1) was newly established from a patient with thyroid cancer and remarkable neutrophilia. NIM‐1 cells also caused severe neutrophilia in nude mice bearing tumors. NIM‐1‐conditioned medium (NIM‐1CM) contained activities that supported not only granulocyte, macrophage and eosinophil colony formation of human bone marrow cells but also the growth of colony‐stimulating factor (CSF)‐dependent cell lines, NFS60‐KX and TF‐1. Northern blot hybridization analysis revealed the constitutive expression of granulocyte‐CSF (G‐CSF), granulocyte/macrophage‐CSF (GM‐CSF) and interleukin(IL)‐6 mRNAs in NIM‐1 cells. Enzyme‐linked immunosorbent assays (ELISA) using NIM‐1CM also confirmed the production of IL‐la and a small amount of IL‐1β besides G‐CSF, GM‐CSF and IL‐6 in NIM‐1 cells. In addition, unexpected production of IL‐11 in NIM‐1 cells was detected by northern blot hybridization analysis and by bioassay using an IL‐11‐dependent cell line. Therefore, NIM‐1 cell line is shown to produce multiple cytokines including potentially megakaryopoietic growth factors such as GM‐CSF, IL‐6 and IL‐11. PMID:1372885

    Full Text Available The aim of this work was to evaluate sex effect on behavior of two commercial broilers lines. Productive parameters, carcass composition and yield, amount and quality of fat deposited in the meat and skin and total body fat were studied. A completely randomized design with four treatments (MR-Male Ross, HR-Female Ross, MAF-Male Avian Farm and HAF-Female Avian Farm and eight repetitions of 40 chickens was used. Animals received water and food ad libitum. After 50 days, two birds (a male and a female per repetition were chosen at random and slaughtered for carcass evaluation. Samples of breast, leg, skin and abdominal fats were analyzed to determine the percentage of intramuscular fat, total cholesterol and fatty acid composition. The Ross line showed higher final weight and weight gain, better intake and feed conversion rate. Also, it was observed that females of both lines had similar results in relation to these parameters. Better yield of breast with bone was found in Ross males and females. In relation to legs and thigh, Ross males showed better results and no differences were observed among females of both lines. Males deposited less fat than females. Finally, differences in percentage of intramuscular fat, content of cholesterol in breast with skin, leg with skin and skin, percentage of saturated, mono and polyunsaturated fatty acids were observed between sex and lines.

    2017-02-01

    Full Text Available For environmentally conscious and sustainable manufacturing, many more manufacturers are acting to recycle and remanufacture their post-consumed products. The most critical process of remanufacturing is disassembly, since it allows for the selective extraction of the valuable components and materials from returned products to reduce the waste disposal volume. It is, therefore, important to design and balance the disassembly line to work efficiently due to its vital role in effective resource usage and environmental protection. Considering the disassembly precedence relationships and sequence-dependent parts removal time increments, this paper presents an improved discrete artificial bee colony algorithm (DABC for solving the sequence-dependent disassembly line balancing problem (SDDLBP. The performance of the proposed algorithm was tested against nine other approaches. Computational results evidently indicate the superior efficiency of the proposed algorithm for addressing the environmental and economic concerns while optimizing the multi-objective SDDLBP.

    Full Text Available The aim of this paper is to establish a general methodology for calculating the costs incurred by employee turnover. This paper deals with identification of costs incurred by the departure of an employee, and does not deal with the cost of recruitment of a new employee. Economic calculations are adjusted to the tax policy in the Czech Republic. The costs of employee turnover (according to Bliss, 2012 include the costs of substitution of the unoccupied position, costs of conducting the exit interview and termination of the contract. The cost of an executive’s time to understand the causes of leaving and costs of the leaving employee’s training were also determined. Important factors in the costs of employee turnover also include the loss of knowledge and possibly also a loss of customers. Costs of lost employee and department productiveness represent an important part of the costs of employee turnover, as well. For all of these costs there have been proposed general calculations formulas.

    Full Text Available This paper highlights the need for using specialised on-line collaborative environments by designers and product engineers who increasingly use Web 2.0 technology to search for information. Although there are professional channels and networks, there is no specific platform which helps during a new product’s conceptualisation phase. Open communication must thus be promoted and encouraged amongst design professionals and companies to form working groups thereby allowing them to work collaboratively in the most open and creative phase of product design, i.e. conceptualisation. The OpenDesigNet (ODN experimental platform has been developed so that designers and small- or medium-sized companies (SMC can access on-line collaborative tools to support the creation and promotion of new on-line products and assess their immediate social impact. This article presents some of the results obtained during the validation phase involving a platform satisfaction survey of design engineering students and has led to a first-hand assessment of the new platform’s potential impact on their professional future.

    1994-01-01

    Integral tritium production and heat deposition measurement in a prototype fusion blanket would enable verification of the computational codes and the data based employed for the calculations. A large number of tritium production rate measurements have been reported for different type of blankets, whereas the direct heat deposition due to the mixed radiation field in the fusion environment, is still in its infancy. In order to ascertain the kerma factors and the photon production libraries, suitable techniques must be developed to directly measure the nuclear heat deposition rates in the materials required for the fusion systems. In this context, at the Lotus facility, we have developed an extremely efficient double ionizing chamber, for the on-line tritium production measurements and employed a pure graphite calorimeter to measure the nuclear heat deposition due to the mixed radiation field of the 14 MeV, Haefely neutron generator. This paper presents both systems and some of the recent measurements. (authors). 8 refs., 13 figs

  16. On-line measurement and control in sustainable mineral processing and energy production

    International Nuclear Information System (INIS)

    Sowerby, B.D.

    2002-01-01

    Sustainable development can be defined as development that 'meets the needs of the present without compromising the ability of future generations to meet their own needs' (WCED, 1987). A sustainable minerals and energy industry will need to achieve a number of related objectives including greater energy efficiency, improved utilisation of ore deposits, improved utilisation of existing plant, improved product quality, reduction of waste material, reduction of pollution levels and improved safety margins. These objectives all relate in varying degrees to the triple bottom line of economic, social and environmental benefits. One critical component in achieving these objectives is to develop and apply improved control systems across the full range of industry applications from mining to processing and utilisation. However process control relies heavily on the availability of suitable on-line process instrumentation to provide the data and feedback necessary for its implementation. There is a lot of truth in the saying 'if you can't measure it you can't control it'. In the past measurement was achieved by manual sampling followed by sample preparation (such as drying, mixing, crushing and dividing) and off-line laboratory analysis. However this procedure is often subject to significant sampling errors and, most importantly, the measurements are too slow for control purposes. By contrast, on-line analysis can provide rapid and accurate measurement in real time thus opening up new possibilities for improved process control. As a result, there has been a rapid increase in the industrial application of on-line analysis instrumentation over the past few decades. The main purpose of this paper is to briefly review some past Australian developments of on-line analysis systems in the mineral and coal industries and to discuss present developments and future trends

  17. Ethanol production from lignocellulosic materials. Fermentation and on-line analysis

    Energy Technology Data Exchange (ETDEWEB)

    Olsson, L.

    1994-04-01

    The fermentation performance of bacteria, yeast and fungi was investigated in lignocellulosic hydrolysates with the aim of finding microorganisms which both withstand the inhibitors and that have the ability to ferment pentoses. Firstly, the performance of Saccharomyces cidri, Saccharomyces cerevisiae, Lactobacillus brevis, Lactococcus lactis ssp lactis, Escherichia coli and Zymomonas mobilis was investigated in spent sulphite liquor and enzymatic hydrolysate of steam-pretreated willow. Secondly, the performance of natural and recombinant E. coli, Pichia stipitis, recombinant S. cerevisiae, S. cerevisiae in combination with xylose isomerase and Fusarium oxysporum was investigated in a xylose-rich acid hydrolysate of corn cob. Recombinant E. coli was the best alternative for fermentation of lignocellulosic hydrolysates, giving both high yields and productivities. The main drawback was that detoxification was necessary. The kinetics of the fermentation with recombinant E. coli KO11 was investigated in the condensate of steam-pretreated willow. A cost analysis of the ethanol production from willow was made, which predicted an ethanol production cost of 3.9 SEK/l for the pentose fermentation. The detoxification cost constituted 22% of this cost. The monitoring of three monosaccharides and ethanol in lignocellulosic hydro lysates is described. The monosaccharides were determined using immobilized pyranose oxidase in an on-line amperometric analyser. Immobilization and characterization of pyranose oxidase from Phanerochaete chrysosporium is also described. The ethanol was monitored on-line using a micro dialysis probe as an in situ sampling device. The dialysate components were then separated in a column liquid chromatographic system and the ethanol was selectively detected by an amperometric alcohol bio sensor. The determinations with on-line analysis methods agreed well with off-line methods. 248 refs, 4 figs, 12 tabs

    Bio-ethanol and biogas produced during the anaerobic conversion of organic compounds has been a subject of great interest since the oil crisis of the 1970s. In ethanol fermentation and anaerobic treatment of wastewaters, end-product (ethanol) and intermediate-products (short-chain fatty acids, SCFA) cause inhibition that results in reduced process efficiency. Control of these constituents is of utmost importance for bioreactor optimization and process stability. Ethanol and SCFA can be detected with precision by capillary gas chromatography usually conducted in off-line measurements. In this work, an on-line monitoring and controlling system was developed and connected to the fermenter via an auto-sampling equipment, which could perform the feeding, filtration and dilution of the sample and final injection into the gas chromatograph through an automation-based programmed procedure. The sample was continuously pumped from the recycle stream of the bioreactor and treated using a microfiltration unit. The concentrate was returned to the reactor while the permeate was quantitatively mixed with an internal standard solution. The system comprised of a gas chromatograph with the flow cell and one-shot sampler and a PC with the appropriate software. The on-line measurement of ethanol and SCFA, directly from the liquid phase of an ethanol fermenter and a high-rate continuous mode anaerobic digester, was accomplished by gas chromatography. Also, this monitoring and controlling system was proved to be effective in the continuous fermentation of alcohol-free beer

    Fever not explained by infection may occur in patients with malignant lymphoma presumably caused by a release of endogenous pyrogen. Although pyrogen has been found in some tumors with a mixed cell population, production of endogenous pyrogen by the neoplastic cells has not been demonstrated. This report documents the apparently spontaneous synthesis and release of such pyrogen by two human tumor cell lines derived from patients with Hodgkin's disease and histiocytic lymphoma. The endogenous pyrogen from the two cell lines was similar and closely resembled that produced by normal human monocytes in antigenic properties as well as heat and pronase sensitivity. The Hodgkin's disease and histiocytic lymphoma cell lines do not require specific stimulation for the production of endogenous pyrogen suggesting that the mechanism of pyrogen release by neoplastic macrophage-related cells differs from that of normal phagocytic cells. The tumor-associated fever in some patients with malignant lymphoma may be caused by a release of endogenous pyrogen by proliferating neoplastic cells.

    Document available in extended abstract form only. The tunnel backfill of Finnish KBS-3V type repository for spent nuclear fuel consists of foundation layer that is installed at site, pre-compacted backfill blocks that fill most of the tunnel and bentonite pellets to fill the gap between blocks and tunnel wall. In order to ensure the quality, availability, and timely delivery of backfill materials and components, and further to ensure the fulfillment of the requirements and specifications set for backfilling of deposition tunnels, the backfill production line was explored step-by-step, and risks related were defined and analyzed. The work described in this paper was initiated by Posiva Oy and is reported in Keto et al. (2012). The first part of the backfill production line is described in Figure 1 for Friedland clay that is designed to be used for the backfill blocks. It consists of excavation, processing and delivery of materials to backfill production facility. Second part of the production line consists of manufacturing of the backfill components, and the third part is the installation. A preliminary risk assessment was done in 2011 for the acquisition of Friedland clay and manufacturing and installation of foundation layer, blocks and pellets. The critical points of the production line were determined using a material flow description where risk is defined as a probability of something unwanted to happen times the severity of the consequences. Risk analysis was performed by going through the whole backfill production line step by step and analyzing all the incidents, which have occurred (or might occur) during the backfilling operations. A risk number from 1 to 25 was given to each step of the chain depending on how long delay the problem causes and how often it occurs. Low risk was the target for each step of the chain, medium risk was considered tolerable, for high risks management actions to decrease the risk number were considered and extremely high risks

    Several viral vaccines, including highly promising vectors such as modified vaccinia Ankara (MVA), are produced on chicken embryo fibroblasts. Dependence on primary cells complicates production especially in large vaccination programs. With primary cells it is also not possible to create packaging lines for replication-deficient vectors that are adapted to proliferation in an avian host. To obviate requirement for primary cells permanent lines from specific tissues of muscovy duck were derived (AGE1.CR, CS, and CA) and further modified: we demonstrate that stable expression of the structural gene pIX from human adenovirus increases titers for unrelated poxvirus in the avian cells. This augmentation appears to be mediated via induction of heat shock and thus provides a novel cellular substrate that may allow further attenuation of vaccine strains.

    This study proposed an alternative to brand loyalty as the explanation for the continued price rigidity of patent-expired brand-name prescription drugs despite the increase in market entry of generic drugs facilitated by the 1984 Drug Price Competition and Patent Term Restoration Act. Study hypotheses were to test (1) whether market entries of new-product extensions are associated with market success of original brand-name drugs before generic drug entry, and (2) whether original brand-name drugs exhibit price rigidity to generic entry only when they are extended. The design is a retrospective follow-up study for the prescription drug brands that lost their patents between 1987 and 1992. The drug brands were limited to nonantibiotic, orally administered drugs containing only 1 active pharmaceutical ingredient. Information on patent expiration, entry of a product extension, and market success were determined from the U.S. Food and Drug Administration.s Orange Book, First DataBank, and American Druggist, respectively. Market success was defined as whether an original drug brand was listed in the top 100 prescriptions most frequently dispensed before facing generic entry. Product-line extension was defined as the appearance of another product that a company introduces within the same market after its existing product. Drug prices were average wholesale prices from the Drug Topics Red Book. The relationship between product-line extension and market success was examined using a logistic regression analysis. The price rigidity to entry was tested using a panel regression analysis. A total of 27 drug brands lost their patents between 1987 and 1992. Drug brands that achieved market success were 16 times more likely to be extended than were those that did not (OR=16, 95% confidence interval, 2.12-120.65). The price rigidity to entry existed in drug brands with extensions (beta=2.65%, P new product-line extension introduced for an original brand helps the original price be

    We have previously demonstrated that both canine and human OSA cell lines, as well as 8 fresh canine OSA tumor samples, exhibit constitutive phosphorylation of STAT3, and that this correlates with enhanced expression of matrix metalloproteinase-2 (MMP2). While multiple signal transduction pathways can result in phosphorylation of STAT3, stimulation of the cytokine receptor gp130 through either IL-6 or Oncostatin M (OSM) is the most common mechanism through which STAT3 is activated. The purpose of this study was to evaluate the role of IL-6 and OSM stimulation on both canine and human OSA cell lines to begin to determine the role of these cytokines in the biology of OSA. RT-PCR and Western blotting were used to interrogate the consequences of OSM and IL-6 stimulation of OSA cell lines. OSA cells were stimulated with OSM and/or hepatocyte growth factor (HGF) and the effects on MMP2 activity (gel zymography), proliferation (CyQUANT), invasion (Matrigel transwell assay), and VEGF production (Western blotting, ELISA) were assessed. The small molecule STAT3 inhibitor LLL3 was used to investigate the impact of STAT3 inhibition following OSM stimulation of OSA cells. Our data demonstrate that the OSM receptor (OSMR), but not IL-6 or its receptor, is expressed by all human and canine OSA cell lines and canine OSA tumor samples; additionally, OSM expression was noted in all tumor samples. Treatment of OSA cell lines with OSM induced phosphorylation of STAT3, Src, and JAK2. OSM stimulation also resulted in a dose dependent increase in MMP2 activity and VEGF expression that was markedly reduced following treatment with the small molecule STAT3 inhibitor LLL3. Lastly, OSM stimulation of OSA cell lines enhanced invasion through Matrigel, particularly in the presence of rhHGF. In contrast, both OSM and HGF stimulation of OSA cell lines did not alter their proliferative capacity. These data indicate OSM stimulation of human and canine OSA cells induces STAT3 activation, thereby

Methods RT-PCR and Western blotting were used to interrogate the consequences of OSM and IL-6 stimulation of OSA cell lines. OSA cells were stimulated with OSM and/or hepatocyte growth factor (HGF and the effects on MMP2 activity (gel zymography, proliferation (CyQUANT, invasion (Matrigel transwell assay, and VEGF production (Western blotting, ELISA were assessed. The small molecule STAT3 inhibitor LLL3 was used to investigate the impact of STAT3 inhibition following OSM stimulation of OSA cells. Results Our data demonstrate that the OSM receptor (OSMR, but not IL-6 or its receptor, is expressed by all human and canine OSA cell lines and canine OSA tumor samples; additionally, OSM expression was noted in all tumor samples. Treatment of OSA cell lines with OSM induced phosphorylation of STAT3, Src, and JAK2. OSM stimulation also resulted in a dose dependent increase in MMP2 activity and VEGF expression that was markedly reduced following treatment with the small molecule STAT3 inhibitor LLL3. Lastly, OSM stimulation of OSA cell lines enhanced invasion through Matrigel, particularly in the presence of rhHGF. In contrast, both OSM and HGF stimulation of OSA cell lines did not alter their proliferative capacity. Conclusions These data indicate OSM stimulation of

    Owing to the higher demands for avoiding medication and antibiotics, health status of the production animals plays an important role in the poultry industry, especially in organic poultry systems. Immunity plays a major role in keeping the host free from disease, and it is evident that the host's genetic make-up influences immunity and disease resistance/susceptibility in chickens. Previously, breeding strategies aimed at selection for resistance against specific diseases with the risk of creating less disease resistance against other pathogens. Changing breeding strategies towards selection of chickens with a more general and broad disease resistance or robustness may therefore improve the overall health status, animal welfare, and food security in the poultry production. The aim of this study was therefore to compare the immunocompetence of the presumed "robust" Hellevad chickens with two chicken lines widely used in organic production, Bovans Brown (Bovans) and Hisex White (Hisex). The chickens were subjected to a routine vaccination program comprising one parasite and four viral vaccines. The current study indicates that considerable differences in immunocompetence may exist between commercial layer lines used in organic production. The Hellevad chickens were found to have higher body weight at the end of the experiment (17 weeks of age) than the other two lines. Furthermore, Hellevad and Hisex chickens were found to have higher levels of humoral innate immunity with regard to sample to positive ratio of natural antibodies in serum and concentration of mannose-binding lectin in serum as compared to Bovans. Moreover, indications of an inflammatory response were observed in the Bovans at week 5, corresponding to 1 week after vaccination with live infectious bursal disease virus. With regard to adaptive immune parameters such as IgY concentration in blood and infectious bursal disease virus (IBDV)-specific antibody titres, the Hellevad and Hisex chickens had lower

    Parasitic Cuscuta reflexa Roxb. possesses many medicinal properties and is a rich source of a variety of biologically relevant natural products. Natural products are the prime source of leads, drugs, and drug templates, and many of the anticancer and antiviral drugs are either based on natural product or derived from them. Cancer is a devastating disease and one of the leading causes of death worldwide despite improvements in patient survival during the past 50 years; new and improved treatments for cancer are therefore actively sought. Colorectal cancer is the fourth most prevalent cancer worldwide and is responsible for nearly 9% of all cancer deaths. Our search for anticancer natural products from C. reflexa has yielded four natural products: Scoparone (1), p-coumaric acid (2), stigmasta-3,5-diene (3) and 1-O-p-hydroxycinnamoylglucose (4) and among them 1-O-p-hydroxycinnamoyldlucose (4) showed promising antiproliferative activities in HCT116 colorectal cell lines, whereas compounds 1-3 showed moderate activities.

    A Spectrometer for On-Line Analysis of Radionuclides (SOLAR) has been installed at a 1 MW TRIGA reactor at Washington State University. Fission product ions from a combination target/ion source located within the thermal column are brought out to a 60 0 magnetic sector mass spectrometer. Surface ionization provides copious beams of Rb + and Cs + ions and less intense beams of Br - and I - ions with negligible contamination by other elements. About 40 fission product nuclides can thus be chemically and physically separated in times of less than 1 second. Past results on independent and cumulative fission yields along with measurements of half-lives of some very neutron-rich nuclides are presented. Current work on delayed-neutron emission probabilities and energy spectra of delayed neutrons from individual nuclides is described. (7 tables, 2 figures) (U.S.)

    2017-09-01

    This article uses the case of pregnancy testing in Britain to investigate the process whereby new and often controversial reproductive technologies are made visible and normalized in mainstream entertainment media. It shows how in the 1980s and 1990s the then nascent product placement industry was instrumental in embedding pregnancy testing in British cinema and television's dramatic productions. In this period, the pregnancy-test close-up became a conventional trope and the thin blue lines associated with Unilever's Clearblue rose to prominence in mainstream consumer culture. This article investigates the aestheticization of pregnancy testing and shows how increasingly visible public concerns about 'schoolgirl mums', abortion and the biological clock, dramatized on the big and small screen, propelled the commercial rise of Clearblue. It argues that the Clearblue close-up ambiguously concealed as much as it revealed; abstraction, ambiguity and flexibility were its keys to success.

    Diets containing 13, 16, 19, or 23% protein and 70% carbohydrate calories were fed to dwarf heterozygote (dw) and normal (Dw) chickens to determine the effects of age (weeks) and protein on intermediary metabolism. In vitro lipogenesis (IVL) was determined by the incorporation of acetate (10 and 20 mM 2 14 C-Acet/2hr) into hepatic fatty acids. Net glucose production (NGP) was determined as the difference in media glucose in the presence or absence of 10 mM pyruvate. Values were expressed per unit of relative liver size (μmoles/100 g BWt). Serum insulin (INS; ng/ml) was determined by homologous radioimmunoassay. Results indicate that although INS was greater in Dw than in dw, this difference was not reflected in a decreased rate of glucose production to accompany the difference in IVL between the two lines. Moreover, an increase in dietary protein resulted in a decrease in IVL but an increase in INS

    Protoporphyrin IX (PpIX) is produced via the heme synthesis pathway by the cell following administration of aminolevulinic acid (ALA). ALA synthase, the enzyme that produces ALA in the cell from glycine and succinyl-coenzyme A, is inhibited in a feedback mechanism by heme and thus is the rate limiting enzyme in the heme synthesis pathway. Since ALA is administered systemically, the rate limiting step that naturally exists in the cells is bypassed, however it is currently unclear why cells have different rate limiting steps in the ALA-PpIX synthesis pathway, and more specifically which types of cancer cells are most productive. It has been determined that when the same amount of ALA is administered to a wide panel of cancer cells in vitro that vastly differing amounts of PpIX are produced. The steps for the ALA-PpIX pathway occur in and around the mitochondria of the cell, but interestingly no correlation is seen between PpIX production and mitochondrial content of the cell, following ALA administration. However, total cell area shows positive correlation with PpIX production. Administration of the iron chelator, 1,2-dimethyl-3-hydroxy-4-pyridone (L1) in combination with ALA allows the final step in the heme synthesis pathway, conversion of PpIX to heme, to be delayed and thus increases the detectable amount of PpIX in each cell line. The cell lines that have the lowest PpIX production following administration of ALA alone show the largest increase in production following the combined administration of ALA and L1. PpIX fluorescence is thought to be a measure of cellular activity and the goal of the current study was to determine which cell lines would be the most promising targets for fluorescence detection or monitoring response to therapy. The results indicate that the cells with larger size and larger numbers of mitochondria may be good potential targets for this therapy. While this conclusion may appear obvious, it is not universally true, and cellular specific

    Full Text Available The paper presents methodology of production control using statistical methods in foundry conditions, using the automatic DISAMATIC molding line. The authors were inspired by many years of experience in implementing IT tools for foundries. The authors noticed that there is a lack of basic IT tools dedicated to specific casting processes, that would greatly facilitate their oversight and thus improve the quality of manufactured products. More and more systems are installed in the ERP or CAx area, but they integrate processes only partially, mainly in the area of technology design and business management from finance and control. Monitoring of foundry processes can generate a large amount of process-related data. This is particularly noticeable in automated processes. An example is the modern DISAMATIC molding line, which integrates several casting processes, such as mold preparation, assembly, pouring or shake out. The authors proposed a methodology that supports the control of the above-mentioned foundry processes using statistical methods. Such an approach can be successfully used, for example, during periodic external audits. The mentioned methodology in the innovative DISAM-ProdC computer tool was implemented.

    As academic health centers face increasing financial pressures, they have adopted a more businesslike approach to planning, particularly for discrete "product" or clinical service lines. Since critical care typically has been viewed as a service provided by a hospital, and not a product line, business plans have not historically been developed to expand and promote critical care. The major focus when examining the finances of critical care has been cost reduction, not business development. We hypothesized that a critical care business plan can be developed and analyzed like other more typical product lines and that such a critical care product line can be profitable for an institution. In-depth analysis of critical care including business planning for critical care services. Regional academic health center in southern New Jersey. None. As part of an overall business planning process directed by the Board of Trustees, the critical care product line was identified by isolating revenue, expenses, and profitability associated with critical care patients. We were able to identify the major sources ("value chain") of critical care patients: the emergency room, patients who are admitted for other problems but spend time in a critical care unit, and patients transferred to our intensive care units from other hospitals. The greatest opportunity to expand the product line comes from increasing the referrals from other hospitals. A methodology was developed to identify the revenue and expenses associated with critical care, based on the analysis of past experience. With this model, we were able to demonstrate a positive contribution margin of dollar 7 million per year related to patients transferred to the institution primarily for critical care services. This can be seen as the profit related to the product line segment of critical care. There was an additional positive contribution margin of dollar 5.8 million attributed to the critical care portion of the hospital stay of

    Obtaining high quality Active Matrix Liquid Crystal (AMLCD) glass to meet the needs of the commercial and military aerospace business is a major challenge, at best. With the demise of all domestic sources of AMLCD substrate glass, the industry is now focused on overseas sources, which are primarily producing glass for consumer electronics. Previous experience with ruggedizing commercial glass leads to the expectation that the aerospace industry can leverage off the commercial market. The problem remains, while the commercial industry is continually changing and improving its products, the commercial and military aerospace industries require stable and affordable supplies of AMLCD glass for upwards of 20 years to support production and maintenance operations. The Boeing Engineering and Supplier Management Process Councils have chartered a group of displays experts from multiple aircraft product divisions within the Boeing Company, the Displays Process Action Team (DPAT), to address this situation from an overall corporate perspective. The DPAT has formulated a set of Common Displays Performance Requirements for use across the corporate line of commercial and military aircraft products. Though focused on the AMLCD problem, the proposed common requirements are largely independent of display technology. This paper describes the strategy being pursued within the Boeing Company to address the AMLCD supply problem and details the proposed implementation process, centered on common requirements for both commercial and military aircraft displays. Highlighted in this paper are proposed common, or standard, display sizes and the other major requirements established by the DPAT, along with the rationale for these requirements.

    Maps, and more importantly Atlases, are assisting the user community in managing a large land area with complex issues, the most complex of which is the management of nuclear waste. The techniques and experiences discussed herein were gained while developing several atlases for use at the US Department of Energy's Hanford Site. The user community requires the ability to locate not only waste sites, but other features as well. Finding a specific waste site on a map and in the field is a difficult task at a site the size of Hanford. To find a specific waste site, the user begins by locating the item or object in an index, then locating the feature on the corresponding map within an atlas. Locating features requires a method for indexing them. The location index and how to place it on a map or atlas is the central theme presented in this article. The user requirements for atlases forced the design team to develop new and innovative solutions for requirements that Product Line Tool Set (PLTS) Map Production System (MPS)-Atlas was not designed to handle.

    To easily and rapidly recover exogenous gene products from chicken egg yolk, we constructed pVTG-catD (VTG, vitellogenin; catD, cathepsin D), a vector cassette carrying two catD-recognition signal peptides (catD-RSPs) in addition to the cloning site. An enhanced green fluorescence protein (EGFP)-encoding DNA fragment was ligated into the pVTG-catD. When the resultant construct pVTG-EGFP-catD containing histidine- and myc-tags was transfected into the chicken hepatoma cell line LMH, EGFP-expression at 24 h post-cultivation was confirmed by fluorescence microscopy. Because a signal peptide (NTVLAEF) encoded in pVTG-EGFP-catD is recognized by catD, the VTG-EGFP fusion protein digested with catD was detectable by Western blotting. Digested exogenous gene product was recovered with nickel resin. These results indicate that catD-recognition sites bearing pVTG-catD and His-tags are functional in chicken LMH cells. Therefore, the system described here may be of use in making excision exogenous gene products in the chicken and in creating homozygous knock-in chickens

    Full Text Available This study used 300 females and 30 males with 36 weeks of age from the selected PP and control PPc maternal broiler lines. PP has been selected for heavy body weight (PC and high egg production for eight generations. Fertile eggs were collected and weighed individually for 4 periods of 5 consecutive days at two-week intervals. In each period, a total of 960 eggs/line were identified and separated in groups of 240 eggs, and stored for later incubation. Embryo weight (PE was evaluated at 9 (P9, 11 (P11, 13 (P13, 15 (P15, 17 (P17 and 21 (P21 days of incubation. The objective was to estimate the effect of selection on embryo development. Egg weight (PO was similar between the two lines. The differences in PE were significant from P15 on, resulting in 1.9g of difference in the chick weight, indicating correlated genetic changes in the embryo development, which can be credited to the selection for PC. Changes in PE while PO was kept unaltered modified the correlations between these two traits. Differences were significant from P13 on and estimated correlations for P21 were 0.72 and 0.70 for PP and PPc, respectively. Chick weight corresponded to 70.91% (PP and 68.48% (PPc of egg weight. The estimated increase in P21 that resulted from the increase of 1.0g in PO was 0.71 in PP and 0.68g in PPc.

  15. Optimal Scheduling of Material Handling Devices in a PCB Production Line: Problem Formulation and a Polynomial Algorithm

    Directory of Open Access Journals (Sweden)

    2008-01-01

    Full Text Available Modern automated production lines usually use one or multiple computer-controlled robots or hoists for material handling between workstations. A typical application of such lines is an automated electroplating line for processing printed circuit boards (PCBs. In these systems, cyclic production policy is widely used due to large lot size and simplicity of implementation. This paper addresses cyclic scheduling of a multihoist electroplating line with constant processing times. The objective is to minimize the cycle time, or equivalently to maximize the production throughput, for a given number of hoists. We propose a mathematical model and a polynomial algorithm for this scheduling problem. Computational results on randomly generated instances are reported.

    Vladimirov, A.A.

    2015-01-01

    We present the generating function approach to the perturbative exponentiation of correlators of a product of Wilson lines and loops. The exponentiated expression is presented in closed form as an algebraic function of correlators of known operators, which can be seen as a generating function for web diagrams. The expression is naturally split onto two parts: the exponentiation kernel, which accumulates all non-trivial information about web diagrams, and the defect of exponentiation, which reconstructs the matrix exponent and is a function of the exponentiation kernel. The detailed comparison of the presented approach with existing approaches to exponentiation is presented as well. We also give examples of calculations within the generating function exponentiation, namely, we consider different configurations of light-like Wilson lines in the multi-gluon-exchange-webs (MGEW) approximation. Within this approximation the corresponding correlators can be calculated exactly at any order of perturbative expansion by only algebraic manipulations. The MGEW approximation shows violation of the dipole formula for infrared singularities at three-loop order.

Three pieces of evidence indicate that the secreted lymphokine was functionally and antigenically very similar, if not identical, to human IL-2: (1) The lymphokine supported the growth of murine IL-2-dependent CTLL-2 cells, which did not respond to human lymphokines other than IL-2, but it did not stimulate the growth of murine IL-3-dependent FDC-P2 cells, (2) the biological activity of the lymphokine was was inhibited by monoclonal antibody (mAb) anti-human-IL-2, and (3) the proliferation of IL-2-dependent cells in the presence of the active materials was completely inhibited by the inclusion of the anti-mouse-IL-2 receptor (IL-2R) mAb. Since leukemia cells of immature B-cell origin also synthesize IL-2R, the human pre-B cell leukemias could represent another type of hematological malignancy where the autocrine processes of IL-2 production and utilization are involved in the expansion of the disease.

  18. Supergravity couplings to Noncommutative Branes, Open Wilson Lines and Generalised Star Products

    Noncommutative gauge theories can be constructed from ordinary U(∞) gauge theories in lower dimensions. Using this construction we identify the operators on noncommutative D-branes which couple to linearized supergravity backgrounds, from a knowledge of such couplings to lower dimensional D-branes with no B field. These operators belong to a class of gauge invariant observables involving open Wilson lines. Assuming a DBI form of the coupling we show, to second order in the gauge potential but to all orders of the noncommutativity parameter, that our proposal agrees with the operator obtained in terms of ordinary gauge fields by considering brane actions in backgrounds and then using the Seiberg-Witten map to rewrite this in terms of noncommutative gauge fields. Our result clarify why a certain commutative but non-associative 'generalized star product' appears both in the expansion of the open Wilson line, as well as in string amplitude computations of open string-closed string couplings. We outline how our procedure can be used to obtain operators in the noncommutative theory which are holographically dual to supergravity modes. (author)

    Full Text Available This paper addresses the issue of work spaces designed based on Activity-Centered Ergonomics. The aim was to reflect on the role of Ergonomics in the design of productive situations in order to anticipate and mitigate the emergence of new constraints. This study was developed using a case study from the packaging industry, where an automated line was implemented to mitigate the injuries suffered as result of the manual system. This article was based on the results of an Ergonomic Work Analysis of the solution implemented, and the subsequent analysis of this design process. It was found that the adopted solution does not have enough leeway for dealing with variations inherent to the process, requiring constant interventions in the operation, by the operators in order to free the line to continue work. It was evident that the adopted solution did not involve the participation of important agents such as the operators and the maintenance crew, giving the project a technical vision that was concerned with eliminating the human factor. The conclusion of this study was that the Ergonomics integrated into the project development favors the collective construction of analysis of the research, and consequently, the development of more effective solutions.

    Use of sunflower (Helianthus annuus L.) for Cu phytoextraction and oilseed production on Cu-contaminated topsoils was investigated in afield trial at a former wood preservation site. Six commercial cultivars and two mutant lines were cultivated in plots with and without the addition of compost (5% w/w) and dolomitic limestone (0.2% w/w). Total soil Cu ranged from 163 to 1170 mg kg(-1). In soil solutions, Cu concentration varied between 0.16-0.93 mg L(-1). The amendment increased soil pH, reduced Cu exposure and promoted sunflower growth. Stem length, shoot and capitulum biomasses, seed yield, and shoot and leaf Cu concentrations were measured. At low total soil Cu, shoot Cu mineralomass was higher in commercial cultivars, Le., Salut, Energic, and Countri, whereas competition and shading affected morphological traits of mutants. Based on shoot yield (7 Mg DW ha(-1)) and Cu concentration, the highest removal was 59 g Cu ha(-1). At high total soil Cu, shoot Cu mineralomass peaked for mutants (e.g., 52 g Cu ha(-1) for Mutant 1 line) and cultivars Energic and Countri. Energic seed yield (3.9 Mg air-DW ha(-1)) would be sufficient to produce oil Phenotype traits and shoot Cu removal depended on sunflower types and Cu exposure.

    The biotechnology and pharmaceutical industries have seen a recent surge in the development of biological drug products manufactured from engineered mammalian cell lines. Since the hugely successful launch of human tissue plasminogen activator in 1987 and erythropoietin in 1988, the biopharmaceutical market has grown immensely. Global sales in 2003 exceeded US 30 billion.1 Currently, a total of 108 biotherapeutics are approved and available to patients (Table 32.1). In addition, 324 medically related, biotechnology-derived medicines for nearly 150 diseases are in clinical trials or under review by the U.S. Food and Drug Administration.2 These biopharmaceutical candidates promise to bring more and better treatments to patients. Compared to small molecule drugs, biotherapeutics show exquisite specificity with fewer off-target interactions and improved safety profiles.

    In California, some 40,000 retailers sell tobacco products. Tobacco's ubiquitousness in retail settings normalizes use and cues smoking urges among former smokers and those attempting cessation. Thus, limiting the number of retailers is regarded as key to ending the tobacco epidemic. In the past decade, independent pharmacies and local grocery chains in California and elsewhere have voluntarily abandoned tobacco sales. No previous studies have examined the reasons for this emerging phenomenon. We sought to learn what motivated retailers to discontinue tobacco sales and what employees and customers thought about their decision. We conducted case studies of seven California retailers (three grocery stores, four pharmacies) that had voluntarily ceased tobacco sales within the past 7 years. We interviewed owners, managers, and employees, conducted consumer focus groups, unobtrusively observed businesses and the surrounding environment, and examined any media coverage of each retailer's decision. We analyzed data using qualitative content analysis. For independent pharmacies, the only reason given for the decision to end tobacco sales was that tobacco caused disease and death. Grocers listed health among several factors, including regulatory pressures and wanting to be seen as "making a difference." Media coverage of stores' new policies was limited, and only three retailers alerted customers. Management reported few or no customer complaints and supportive or indifferent employees. Pharmacy employees were pleased to no longer be selling a deadly product. Grocery store management saw the decision to end tobacco sales as enhancing the stores' image and consistent with their inventory of healthy foods. Focus group participants (smokers and nonsmokers) were largely unaware that retailers had stopped selling tobacco; however, almost all supported the decision, viewing it as promoting public health.

    The current competitive situation increases the importance of realistically estimating product costs during the early phases of product and assembly line planning projects. In this article, several multi-objective algorithms using difference dominance rules are proposed to solve the problem associated with the selection of the most effective combination of product and assembly lines. The list of developed algorithms includes variants of ant colony algorithms, evolutionary algorithms and imperialist competitive algorithms. The performance of each algorithm and dominance rule is analysed by five multi-objective quality indicators and fifty problem instances. The algorithms and dominance rules are ranked using a non-parametric statistical test.

  10. Sustainable production of azadirachtin from differentiated in vitro cell lines of neem (Azadirachta indica)

    2013-01-01

    Azadirachtin has high industrial demand due to its immediate application as an ecofriendly, biodegradable biopesticide and also due to its various other significant bioactivities. To date, the only commercially feasible way to produce azadirachtin is extraction from seeds, but their availability is very limited as the tree flowers only once a year and only one-third of the fruits are collected due to operational problems. Further, due to the strict out-breeding nature of the plant, the seeds are highly heterozygous, resulting in inconsistent metabolite production. Therefore, in the present study, to achieve sustainable production of azadirachtin, dedifferentiated and redifferentiated calli derived from various explants of neem—zygotic embryo, leaf and ovary—were investigated for their potential to biosynthesize azadirachtin. High-performance liquid chromatography analysis of the in vitro cell lines showed the presence of azadirachtin in all the samples tested, the content of which in cultured cells varied with explant source and cell differentiation response. The presence of azadirachtin in samples was further confirmed by positive electrospray ionization mass spectroscopy. The zygotic embryo cultures of neem accumulated much higher amounts of azadirachtin than leaf and ovary cultures. Furthermore, organized in vitro callus cultures (redifferentiated) supported higher azadirachtin biosynthesis, while unorganized callus cultures (dedifferentiated) supported the least. The maximum azadirachtin content of 2.33 mg g−1 dry weight was obtained from redifferentiated immature zygotic embryo cultures.

  11. Decreased immunoglobulin production by a human lymphoid cell line following melphalan treatment

    1982-11-01

    The effect of melphalan on immunoglobulin G (IgG) production by a human lymphoblastoid cell line (BF) was studied. The amount of secreted IgG and the percentage of cells containing cytoplasmic IgG were measured by immunoassay and cytofluorometry, respectively. Dose-response studies indicated that melphalan concentrations of 2 x 10/sup -8/ M had no effect, while concentrations of 8 x 10/sup -7/ M were totally toxic, after 72-h exposures to the drug. Statistically significant, persistent, alterations in both synthesis and secretion of IgG by BF cells were observed following treatment for 72 h with 4 x 10/sup -7/ M melphalan, and there was an increase in population-doubling time from 24 to 72 h in these drug-treated cells. The percentage of IgG-containing cells in melphalan-treated cultures was significantly decreased as compared to control cultures. IgG secretion was also decreased in these cultures, and the variation in IgG secretion as a function of cellular growth was significantly altered following melphalan treatment. Decreased IgG production following melphalan treatment may be related to altered cell cycle kinetics. Based on immunological analysis, there was no evident alteration in the IgG secreted by melphalan-treated cells, nor did melphalan treatment produce a cellular population lacking IgG entirely.

    Keeping dairy cows in grassland systems relies on detailed analyses of genetic resistance against endoparasite infections, including between- and within-breed genetic evaluations. The objectives of this study were (1) to compare different Black and White dairy cattle selection lines for endoparasite infections and (2) the estimation of genetic (co)variance components for endoparasite and test-day milk production traits within the Black and White cattle population. A total of 2,006 fecal samples were taken during 2 farm visits in summer and autumn 2015 from 1,166 cows kept in 17 small- and medium-scale organic and conventional German grassland farms. Fecal egg counts were determined for gastrointestinal nematodes (FEC-GIN) and flukes (FEC-FLU), and fecal larvae counts for the bovine lungworm Dictyocaulus viviparus (FLC-DV). The lowest values for gastrointestinal nematode infections were identified for genetic lines adopted to pasture-based production systems, especially selection lines from New Zealand. Heritabilities were low for FEC-GIN (0.05-0.06 ± 0.04) and FLC-DV (0.05 ± 0.04), but moderate for FEC-FLU (0.33 ± 0.06). Almost identical heritabilities were estimated for different endoparasite trait transformations (log-transformation, square root). The genetic correlation between FEC-GIN and FLC-DV was 1.00 ± 0.60, slightly negative between FEC-GIN and FEC-FLU (-0.10 ± 0.27), and close to zero between FLC-DV and FEC-FLU (0.03 ± 0.30). Random regression test-day models on a continuous time scale [days in milk (DIM)] were applied to estimate genetic relationships between endoparasite and longitudinal test-day production traits. Genetic correlations were negative between FEC-GIN and milk yield (MY) until DIM 85, and between FEC-FLU and MY until DIM 215. Genetic correlations between FLC-DV and MY were negative throughout lactation, indicating improved disease resistance for high-productivity cows. Genetic relationships between FEC-GIN and FEC-FLU with milk

    Full Text Available ABSTRACT Estimating stability and adaptability parameters of cultivars is a widely used study to access the genotype × environment interaction, in order to identify the best genotypes for each cultivation area. In this study, the adaptability and stability parameters were estimated in eight high-oleic lines and two peanut cultivars in 11 experiments in the State of São Paulo, Brazil, from 2008 to 2013, based on the data of the plots mean productivity (Kg·ha–1, with the objective of recommending the most productive genotypes in peanut producing regions in the State of São Paulo. The design used for these experiments was the randomized complete blocks, with four replications. Lines L. 599 and L. 551 were the best genotypes regarding overall adaptability and stability in yield, considering the methods of Eberhart and Russell and of Lin and Binns modified by Carneiro. Results produced by both methods were convergent as for the classification of the lines, and the use of one of them would not be detrimental to the recommendation of productive lines associated to production adaptability and stability. The overall adaptability in addition to the stability in the productivity of the lines here evaluated showed outstanding performance in relation to the cultivars IAC Caiapó and Runner IAC 886.

    Innovative organisations need creative employees who generate new ideas for product or process innovation. This paper presents a conceptual framework for the effect of personal, social-organisational and physical factors on employee creativity. Based on this framework, an instrument to analyse the extent to which the work environment enhances creativity is developed. This instrument was applied to a sample of 409 employees and support was found for the hypothesis that a creative work environment enhances creative performance. This paper illustrates how the instrument can be used in companies to select and implement improvements. STATEMENT OF RELEVANCE: The ergonomics discipline addresses the work environment mainly for improving health and safety and sometimes productivity and quality. This paper opens a new area for ergonomics: designing work environments for enhancing employee creativity in order to strengthen an organisation's capability for product and process innovation and, consequently, its competitiveness.

  17. Tuberculosis drug issues: prices, fixed-dose combination products and second-line drugs.

    Laing, R O; McGoldrick, K M

    2000-12-01

    Access to tuberculosis drugs depends on multiple factors. Selection of a standard list of TB drugs to procure is the first step. This paper reviews the advantages and disadvantages of procuring and using fixed-dose combination (FDC) products for both the intensive and continuation phases of treatment. The major advantages are to prevent the emergence of resistance, to simplify logistic management and to reduce costs. The major disadvantage is the need for the manufacturers to assure the quality of these FDCs by bioavailability testing. The paper reports on the inclusion of second-line TB drugs in the 1999 WHO Essential Drug List (EDL). The need to ensure that these drugs are used within established DOTS-Plus programs is stressed. The price of TB drugs is determined by many factors, including producer prices, local taxes and duties as well as mark-ups and fees. TB drug prices for both the public and private sectors from industrialized and developing countries are reported. Price trends over time are also reported. The key findings of this study are that TB drug prices have generally declined in developing countries while they have increased in developed countries, both for the public and private sectors. Prices vary between countries, with the US paying as much as 95 times the price paid in a specific developing country. The prices of public sector first-line TB drugs vary little between countries, although differences do exist due to the procurement methods used. The price of tuberculin, a diagnostic agent, has increased dramatically in the US, with substantial inter-country variations in price. The paper suggests that further research is necessary to identify the reasons for the price disparities and changes over time, and suggests methods which can be used by National Tuberculosis Programme managers to ensure availability of quality assured TB drugs at low prices.

    Full Text Available RQ: Is there a connection among perception of hostile and unethical communication, timely removal of causes and employee satisfaction?Purpose: Perceived mobbing in the organization, analysing causes and timely removal of them without any effect; achieve an environment of satisfied employees. The purpose is to study the relationship amongthe categories: perceiving mobbing, removing the effects, employee satisfaction.Methods: Qualitative research approach, method of interview by using the seven steps principles.Results: The findings clearly state that being aware of the negative factors and psychological abuse in organizations was present. The interview participants perceived different negative behaviours especially by the female population and from the side of superiors. In some organizations perceived negative factors are insults,insinuations, low wages, inadequate working day, competition, lobbying, and verbal threats. All negative factors lead to serious implications for employees, in which the organization can lose its reputation, productivity is reduced, costs of employment can increase with more sick leaves and in extreme cases, the results can be soserious that the organization can end in bankruptcy or liquidation.Organization: The result of the study warns management to acceptcertain actions and remediate the situation in organizations. The employer and managers must do everything to protect their subordinates from violence and potential offenders.Society: The research study warns on the seriousness of mobbing among employees, the aim is to bring the issue to individuals and society. The victim usually needs help (health costs, losses in the pension system, increased unemployment, and lower productivity of the whole society.Originality: In view of the sensitivity of the issues, the author concludes that the existing research studies are based especially on closed questions (questionnaires; however, interviews create mutual trust between

  19. The use of statistical procedures for comparison of the production of eggs considering different treatments and lines of quails

    2012-04-01

    Full Text Available To make inferences concerning a population, parametric methods are traditionally used for sample data analysis assuming that these come from ordinary populations, which not always happens. Most of the times such assumption leads to inadequate conclusions and decisions, especially when the data are distributed asymmetrically. It was aimed on this work to adjust some plausible models for this type of data, aiming to compare eggs productions in quails of different lines through frequentist and Bayesian methods. In the analyzed data it could be verified that the parametric and non-parametric frequentist procedures were, in general, equally conclusive. The Bayesian procedure was the only one which detected difference between the yellow and red lines, regarding the preconized energy diet, and between the blue and yellow for the second eclosion group. By the frequentist methods differences between the blue and red lines were not found; however, given a Poisson distribution for the eggs production, through multiple comparisons between the posterior mean under the Bayesian focus, differences were found between all lines. For being more sensitive, besides flexible, such procedure detected differences not observed by the traditional methods between the yellow and red lines, in the higher energy diet; between the blue and the red one in the second eclosion group and in general. It was concluded that quails of the yellow line showed bigger eggs production, regardless of the eclosion group and diet. Such results raise the discussion on the appropriate use of methods and procedures for statistical data analysis.

  2. Interferon production and signaling pathways are antagonized during henipavirus infection of fruit bat cell lines.

    Directory of Open Access Journals (Sweden)

    Elena R Virtue

    Full Text Available Bats are natural reservoirs for a spectrum of infectious zoonotic diseases including the recently emerged henipaviruses (Hendra and Nipah viruses. Henipaviruses have been observed both naturally and experimentally to cause serious and often fatal disease in many different mammal species, including humans. Interestingly, infection of the flying fox with henipaviruses occurs in the absence of clinical disease. The extreme variation in the disease pattern between humans and bats has led to an investigation into the effects of henipavirus infection on the innate immune response in bat cell lines. We report that henipavirus infection does not result in the induction of interferon expression, and the viruses also inhibit interferon signaling. We also confirm that the interferon production and signaling block in bat cells is not due to differing viral protein expression levels between human and bat hosts. This information, in addition to the known lack of clinical signs in bats following henipavirus infection, suggests that bats control henipavirus infection by an as yet unidentified mechanism, not via the interferon response. This is the first report of henipavirus infection in bat cells specifically investigating aspects of the innate immune system.

IoT systems are usually composed of heterogeneous and interconnected lightweight devices that support applications that are subject to change in their external environment and in the functioning of these devices. The management of the variability of these changes, autonomously, is a challenge in the development of these systems. Agents are a good option for developing self-managed IoT systems due to their distributed nature, context-awareness and self-adaptation. Our goal is to enhance the development of IoT applications using agents and software product lines (SPL). Specifically, we propose to use Self-StarMASMAS, multi-agent system) agents and to define an SPL process using the Common Variability Language. In this contribution, we propose an SPL process for Self-StarMAS, paying particular attention to agents embedded in sensor motes.

    2003-10-01

    The ISOL (isotope separation on line) allows the production of secondary radioactive ion beams through spallation or fragmentation or fission reactions that take place in a thick target bombarded by a high intensity primary beam. The challenge is to increase the intensity and purity of the radioactive beam. The optimization of the system target/source requires the right choice of material for the target by taking into account the stability of the material, its reactivity and the ionization method used. The target is an essential part of the system because radioactive elements are generated in it and are released more or less quickly. Tests have been made in order to select the best fitted material for the release of S, Se, Te, Ge and Sn. Materials tested as target filling are: ZrO 2 , Nb, Ti, V,TiO 2 , CeO x , ThO 2 , C, ZrC 4 and VC). Other molecules such as: COSe, COS, SeS, COTe, GeS, SiS, SnS have been studied to ease the extraction of recoil nuclei (Se, S, Te, Ge and Sn) produced inside the target

    By means of a model the use of electronic data processing is studied for preparing inventory listings and for inventory verification in a fabrication plant for Pu-U mixed-oxide fuel pins. It is postulated that interruptions in operation should be avoided as much as possible. Closed-Line production is assumed so that access to nuclear material calls for special withdrawal via locks. The production line is subdivided into sections with measuring points placed in between to record the nuclear material flow. The measured results are fed to a central data acquisition and reporting system capable of calculating on-line from these results the book inventories present in the individual sections. Inventory-taking and verification are carried out simultaneously in the sections of the production line using the EDP system. The production is not interrupted for this purpose. The production stream is tagged prior to reaching a section to be measured and is subsequently measured when entering the respective section until the tag has reached the end of the section. The measurement can be verified by inspectors. Movements of nuclear materials in and from other plant areas such as the storage area are likewise fed into the central data processing system so that inventory lists can be recalled at any moment. By this means the inventory can be taken quickly and at any time. The inventory is verified in the conventional way. (author)

    Recombinant factor VII (rFVII) is the main therapeutic choice for hemophilia patients who have developed inhibitory antibodies against conventional treatments (FVIII and FIX). Because of the post-translational modifications, rFVII needs to be produced in mammalian cell lines. In this study, for the first time, we have shown efficient rFVII production in HepG2, Sk-Hep-1, and HKB-11 cell lines. Experiments in static conditions for a period of 96 h showed that HepG2-FVII produced the highest amounts of rhFVII, with an average of 1843 ng/mL. Sk-hep-1-FVII cells reached a maximum protein production of 1432 ng/mL and HKB-11-FVII cells reached 1468 ng/mL. Sk-Hep-1-rFVII and HKB-11-rFVII were selected for the first step of scale-up. Over 10 days of spinner flask culture, HKB-11 and SK-Hep-1 cells showed a cumulative production of rFVII of 152 μg and 202.6 μg in 50 mL, respectively. Thus, these human cell lines can be used for an efficient production of recombinant FVII. With more investment in basic research, human cell lines can be optimized for the commercial production of different bio therapeutic proteins. Copyright © 2017 Elsevier Inc. All rights reserved.

    Suboptimal employee decisions are prevalent in employee benefit plans. Poor decisions have significant consequences for employees and employers. Improving participant decisions produces beneficial outcomes such as lower labor costs, higher productivity and better workforce management. The business case for employee benefits can be strengthened by applying lessons learned from the field of behavioral economics to employee benefit plan design and to workforce communication. This article explains the types of behavioral biases that influence suboptimal decisions and explores how enlightened employee benefit plan choice architecture and vivid behavioral messaging contribute to human and better organizational outcomes.

    Full Text Available In the present study, the impact of Salmonella Typhimurium on cell-mediated immunity (CMI was investigated in 5 week-old immuno divergent broiler lines selected for the high and low response to phytohemagglutinin-P. The immune response was assessed in peripheral-blood mononuclear cells (PBMCs induced with Salmonella Typhimurium at different time intervals (0 h, 0.5 h, 2 h, 4 h, 6 h, 12 h and 24 h. The differential mRNA expression patterns of IFN-γ, IL-2 and iNOS were evaluated by quantitative real time PCR. In-vitro production of nitric oxide (NO was also estimated in the culture supernatant and correlated with iNOS mRNA expression. Present study showed higher production of NO in the high cell-mediated line (HCMI as compared to the low cell-mediated line (LCMI upon stimulation with Salmonella Typhimurium. Correspondingly, higher mRNA expression of iNOS and IFN-γ were observed in high response birds (HCMI; but IL-2 was down regulated in this line compared to the low response birds (LCMI. Significantly (p<0.05 higher expression of iNOS, IFN-γ and higher production of NO in high line indicated that the selection for PHA-P response might be employed for increasing the immune competence against Salmonella Typhimurium in chicken flocks.

  11. Self-certification and employee training of mail-order distributors of scheduled listed chemical products. Interim final rule with request for comment.

    Science.gov (United States)

    2011-04-13

    On October 12, 2010, the President signed the Combat Methamphetamine Enhancement Act of 2010 (MEA). It establishes new requirements for mail-order distributors of scheduled listed chemical products. Mail-order distributors must now self-certify to DEA in order to sell scheduled listed chemical products at retail. Sales at retail are those sales intended for personal use; mail-order distributors that sell scheduled listed chemical products not intended for personal use, e.g., sale to a university, are not affected by the new law. This self-certification must include a statement that the mail-order distributor understands each of the requirements that apply under part 1314 and agrees to comply with these requirements. Additionally, mail-order distributors are now required to train their employees prior to self certification. DEA is promulgating this rule to incorporate the statutory provisions and make its regulations consistent with the new requirements and other existing regulations related to self-certification.

  12. Environmental and life cycle analysis of a biodiesel production line from sunflower in the Province of Siena (Italy)

    2013-01-01

    The Directive 2009/28/EC established the overall target that 20% of energy consumption should be represented by renewable energy sources by 2020 in each European member state. Furthermore, the Directive sets a mandatory 10% minimum target for biofuels in the transport sector. Biofuels are potentially an important alternative to mineral diesel. We propose a pilot production line of biodiesel from sunflower on local scale in the Province of Siena (Tuscany) to research a possible reduction of fossil fuel consumption in the transport sector. This study might represent an opportunity to reduce petroleum dependence in the transport sector. Environmental Impact Indicators were provided by Material Flow Accounting, Embodied Energy Analysis and Emergy Accounting. Results showed that agricultural phase is the critical step in the production line. A comparative Life Cycle Assessment analysis for the biodiesel production line with mineral diesel production showed environmental advantages of the biofuel production, however requiring a higher land demand. Therefore, biodiesel may not the optimal solution on large scale but might be a good alternative to fossil fuel. This would depend upon the entire production cycle taking place in a limited area. This is necessary in order to fulfill the needs of local farms and small enterprises. - Highlights: • Environmental profile of the biodiesel production from sunflower was evaluated. • Agricultural phase is the critical step in the whole production line. • Biodiesel from sunflower cannot be considered a totally renewable energy source. • Biodiesel shows advantages in respect to mineral diesel but a higher land demand. • Biodiesel mix may be a good solution on local scale

    Monoclonal antibodies are commercially important, high value biotherapeutic drugs used in the treatment of a variety of diseases. These complex molecules consist of two heavy chain and two light chain polypeptides covalently linked by disulphide bonds. They are usually expressed as recombinant proteins from cultured mammalian cells, which are capable of correctly modifying, folding and assembling the polypeptide chains into the native quaternary structure. Such recombinant cell lines often vary in the amounts of product produced and in the heterogeneity of the secreted products. The biological mechanisms of this variation are not fully defined. Here we have utilised experimental and modelling strategies to characterise and define the biology underpinning product heterogeneity in cell lines exhibiting varying antibody expression levels, and then experimentally validated these models. In undertaking these studies we applied and validated biochemical (rate-constant based) and engineering (nonlinear) models of antibody expression to experimental data from four NS0 cell lines with different IgG4 secretion rates. The models predict that export of the full antibody and its fragments are intrinsically linked, and cannot therefore be manipulated individually at the level of the secretory machinery. Instead, the models highlight strategies for the manipulation at the precursor species level to increase recombinant protein yields in both high and low producing cell lines. The models also highlight cell line specific limitations in the antibody expression pathway.

  2. Development and application of an on-line tritium production rate measuring method

    International Nuclear Information System (INIS)

    Yamaguchi, Seiya

    1989-06-01

    A highly sensitive on-line method for measuring the tritium production rate (TPR) of 6 Li was developed using the response difference of 6 Li and 7 Li-glass scintillators in a mixed neutron-gamma radiation field. A fitting method for subtracting the pulse height spectrum of 7 Li-glass from that of 6 Li-glass was introduced. The contribution of competing reactions such as 6 Li (n, n 'd) 4 He was estimated by kinematical analyses. An absolute value of the 6 Li content was determined by a chemical analysis. The thermal flux perturbation due to 6 Li-glass of various thickness and 6 Li contents was evaluated by measurement in a thermal neutron field and calculation by the modified Skyrme theory. A Monte Carlo calculation of the self-shielding effect was also made. The dependence of the self-shielding on neutron energy was examined by this Monte Carlo code. The edge effect, i.e., distortion of the pulse height spectrum due to partial energy deposition of the alpha and/or the triton, was investigated by measurement in a thermal neutron field and by a Monte Carlo simulation that was based on the scintillation mechanism and considered Bragg absorption and the ratio of contributions to luminescence by the alpha and the triton. The dependence of the edge effect on neutron energy was examined by this Monte Carlo code. This method was applied to the measurement of TPR distributions in simulated fusion blanket assemblies bombarded by D-T neutrons. Absolute values of the TPR were obtained with an experimental error of 3∼6 %. The measured results were compared with those of conventional β-counting methods and good agreement was obtained. An optical fiber system, using miniature lithium-glass scintillators, was fabricated for purpose of microminiaturization of detector size and adaption to strong electromagnetic field. Applicability of this system to a D-T neutron field was demonstrated. (author)

  3. Evaluation of the agronomic performance of atrazine-tolerant transgenic japonica rice parental lines for utilization in hybrid seed production.

    Directory of Open Access Journals (Sweden)

    Luhua Zhang

    Full Text Available Currently, the purity of hybrid seed is a crucial limiting factor when developing hybrid japonica rice (Oryza sativa L.. To chemically control hybrid seed purity, we transferred an improved atrazine chlorohydrolase gene (atzA from Pseudomonas ADP into hybrid japonica parental lines (two maintainers, one restorer, and Nipponbare, by using Agrobacterium-mediated transformation. We subsequently selected several transgenic lines from each genotype by using PCR, RT-PCR, and germination analysis. In the presence of the investigated atrazine concentrations, particularly 150 µM atrazine, almost all of the transgenic lines produced significantly larger seedlings, with similar or higher germination percentages, than did the respective controls. Although the seedlings of transgenic lines were taller and gained more root biomass compared to the respective control plants, their growth was nevertheless inhibited by atrazine treatment compared to that without treatment. When grown in soil containing 2 mg/kg or 5 mg/kg atrazine, the transgenic lines were taller, and had higher total chlorophyll contents than did the respective controls; moreover, three of the strongest transgenic lines completely recovered after 45 days of growth. After treatment with 2 mg/kg or 5 mg/kg of atrazine, the atrazine residue remaining in the soil was 2.9-7.0% or 0.8-8.7% respectively, for transgenic lines, and 44.0-59.2% or 28.1-30.8%, respectively, for control plants. Spraying plants at the vegetative growth stage with 0.15% atrazine effectively killed control plants, but not transgenic lines. Our results indicate that transgenic atzA rice plants show tolerance to atrazine, and may be used as parental lines in future hybrid seed production.

    2017-03-01

    Full Text Available Purpose: The objective of this publication is to identify ways to increase employee engagement in Bulgarian business organizations and identify how such employee engagement affects employee and company performance. Design/methodology/approach: Our research is based on the evaluation of employee engagement methodologies used by well-known companies such as Gallup HCM Advisory Group, Deloitte and Aon Hewitt. Based on these, we derive the factors influencing employee engagement in Bulgarian companies. Findings: This work focuses on management, in recent years, aimed at retaining and developing the best employees, and their evolution into reliable potential leaders of the organization. This is undertaken to maintain and increase the number of those engaged in the business of company employees as well. The management of a successful leader is considered key to increasing employee engagement. Employee commitment implies something special, additional or atypical in the performance of tasks and job role. This is a behaviour that involves innovation, demonstrating initiative via proactive seeking of opportunities that contribute to the company and exceeding the expected standard of employee performance. The findings can strengthen the already-significant role of management. There is no universal way to increase employee engagement and motivation towards increased productivity, activity, and creativity. Research limitations/implications: The study has been undertaken for employees in Bulgaria.

  8. Surface inspection of flat products by means of texture analysis: on-line implementation using neural networks

    Science.gov (United States)

    Fernandez, Carlos; Platero, Carlos; Campoy, Pascual; Aracil, Rafael

    1994-11-01

    This paper describes some texture-based techniques that can be applied to quality assessment of flat products continuously produced (metal strips, wooden surfaces, cork, textile products, ...). Since the most difficult task is that of inspecting for product appearance, human-like inspection ability is required. A common feature to all these products is the presence of non- deterministic texture on their surfaces. Two main subjects are discussed: statistical techniques for both surface finishing determination and surface defect analysis as well as real-time implementation for on-line inspection in high-speed applications. For surface finishing determination a Gray Level Difference technique is presented to perform over low resolution images, that is, no-zoomed images. Defect analysis is performed by means of statistical texture analysis over defective portions of the surface. On-line implementation is accomplished by means of neural networks. When a defect arises, textural analysis is applied which result in a data-vector, acting as input of a neural net, previously trained in a supervised way. This approach tries to reach on-line performance in automated visual inspection applications when texture is presented in flat product surfaces.

    From July 2000 to July 2001, the hazard analysis and critical control points (HACCP) system was implemented to the benefit of the traditional sandwich production in Phnom Penh City Sandwiches were initially analyzed for bacterial indicators among 6 large-scale producers during a 2 months period. In the second stage of the study, two selected producers were involved in the HACCP process. Microbiological analyses revealed a poor sanitary quality of samples from all the production lines tested. Implementation of HACCP method resulted in a reduction of microbial contamination, but this decrease was not significant compared with others steps of HACCP process (chi2 test for trend, p > 0.05). HACCP system was well accepted by producers but routine practices and wrong perception by production-line workers did limit the success of the process. A regulation on the mass catering sector should be part of a large strategy of food safety and environmental health in the city.

    1986-01-01

    A cell culture system was developed for the continuous and efficient production of acquired immune deficiency syndrome (AIDS) retrovirus. After infection of a human T-cell line Molt-4 with HTLV-III and LAV the cells grow permanently and produce large amounts of virus continuously. The yields of production of virus were assessed either with reverse transcriptase activity or a newly established biological quantitation assay of active virus. The amounts of virus with this cell system were much higher than those of the H9 cell system. This procedure enabled us first to compare the two viral isolates HTLV-III and LAV directly in the same cell lines. Establishment of the culture system, allowing efficient production of AIDS retroviruses, provides a useful tool for the isolation of the virus from patients with AIDS and for more basic research, such as the mechanisms of immune destruction caused by the virus leading to the occurence of various malignancies (author)

    The performance of many contemporary detergent products critically depends on polymers. Water-soluble polycarboxylates represent an important class of detergent polymers, and their quantitative assessment in detergent matrices stands as a considerable challenge. The presence of high levels of surfactants is a major complication, due to the strong tendency of surfactants to form micelles and to interact with the polymers. First, we addressed critical steps in the subsequent combined use of liquid extraction and off-line size exclusion chromatography-nuclear magnetic resonance (SEC-NMR) for identification and quantification of polycarboxylates in detergent products. Next, the different steps in the off-line SEC-NMR procedure were optimized with respect to precision and accuracy. This resulted in recoveries of more than 80% for maleic acid/acrylic acid copolymers; in detergent products a proportional bias of 30% is achieved. The method showed good precision with a relative standard deviation of within-laboratory reproducibility between 5% and 14%.

Deficiency of EPO is known to cause anemia in chronically infected renal patients and they require regular blood transfusion. Availability of recombinant EPO has eliminated the need for blood transfusion and now it is extensively used for the treatment of anemia. Glycosylation of erythropoietin is essential for its secretion, stability, protein conformation and biological activity. However, maintenance of human like glycosylation pattern during manufacturing of EPO is a major challenge in biotechnology. Currently, Chinese hamster ovary (CHO cell line is used for the commercial production of erythropoietin but this cell line does not maintain glycosylation resembling human system. With the trend to eliminate non-human constituent from biopharmaceutical products, as a preliminary approach, we have investigated the potential of human hepatoma cell line (Huh-7 to produce recombinant EPO. Materials and methods Initially, the secretory signal and Kozak sequences was added before the EPO mature protein sequence using overlap extension PCR technique. PCR-amplified cDNA fragments of EPO was inserted into mammalian expression vector under the control of the cytomegalovirus (CMV promoter and transiently expressed in CHO and Huh-7 cell lines. After RT-PCR analysis, ELISA and Western blotting was performed to verify the immunochemical properties of secreted EPO. Results Addition of secretory signal and Kozak sequence facilitated the extra-cellular secretion and enhanced the expression of EPO protein. Significant expression (P Conclusion Huh-7 cell line has a great potential to produce glycosylated EPO, suggesting the use of this cell line to produce glycoproteins of the therapeutic importance resembling to the natural human system.

    Surveys indicate that when new rules on expensing stock options take effect, many companies are likely to limit the number of employees who can receive equity compensation. But companies that reserve equity for executives are bound to suffer in the long run. Study after study proves that broad-based ownership, when done right, leads to higher productivity, lower workforce turnover, better recruits, and bigger profits. "Done right" is the key. Here are the four most important factors in implementing a broad-based employee equity plan: A significant portion of the workforce--generally, most of the full-time people--must hold equity; employees must think the amounts they hold can significantly improve their financial prospects; managerial practices and policies must reinforce the plan; and employees must feel a true sense of company ownership. Those factors add up to an ownership culture in which employees' interests are aligned with the company's. The result is a workforce that is loyal, cooperative, and willing to go above and beyond to make the organization successful. A wide variety of companies have recorded exceptional business performance with the help of employee-ownership programs supported by management policies. The authors examine two: Science Applications International, a research and development contractor, and Scot Forge, which shapes metal and other materials for industrial machinery. At both companies, every employee with a year or so of service holds equity, and employees who stay on can accumulate a comfortable nest egg. Management's sharing of financial information reinforces workers' sense of ownership. So does the expectation that employees will accept the responsibilities of ownership. Workers with an ownership stake internalize their responsibilities and feel they have an obligation not only to management but to one another.

    The seeds of a barley cultivar, Chikurinibaraki No.1 and of an early mutant line, Ea 52, derived from it were exposed to the external irradiation of gamma ray and thermal neutrons, and to the internal irradiation with the alpha ray from the nuclear reaction B-10 (n, alpha) Li-7 generated by the thermal neutron irradiation of B-10 imbibed seeds. The reciprocal translocation induced by these irradiation was detected and bred in the pedigrees of irradiated materials by the selection in terms of the partial sterility of seeds. The examination of seed fertility and chromosome pairing at the MI of meiosis of the F/sub 1/ hybrid between the selected lines and the original cultivar was also used. Consequently, 50 homozygous lines of reciprocal translocation were confirmed. The tester lines for translocated chromosomes were established by the cytological examination of the chromosome pairing in the hybrids between each two of the tester lines. The investigation of the inheritance of translocation heterozygotes showed that most of the newly obtained lines differently behaved from the expectation on the genetical basis of reciprocal translocation.

    Employees, many of whom are not native English speakers, perform the majority of work on large US dairy farms. Although management of employees is a critical role of dairy owners and managers, factors that improve employee engagement and retention are not well known. Objectives were to (1) identify key dairy farm employee management issues based on employee perceptions, (2) evaluate strengths and weaknesses of farms based on employee responses, (3) investigate differences between Latino and English-speaking employees, and (4) investigate differences in perception between employers and employees. Employees from 12 US dairy farms (each with a minimum of 10 employees) were interviewed by phone following a questionnaire provided. Employees provided their responses to 21 Likert scale questions and 8 open-ended questions. There was a wide range in employee turnover among farms (100%). Latino employees had much shorter tenure and were more often employed in milking and livestock care than English-speaking employees. Employee perceptions differed among farms regarding whether they would recommend their farm as a place to work, teamwork within the dairy, whether rules were fairly applied, availability of tools and equipment, clear lines of supervision, and recognition for good work in the previous 15 d. Latino employees (n = 91) were more positive in many of these measures than their English-speaking counterparts (n = 77) but less often provided ideas to their employer on how to improve the business. Employers, surveyed on how they thought their employees would answer, underestimated employee responses on several questions, particularly the interest of employees in learning about dairy. When asked to cite 3 goals of the operation, there were differences among owners, managers, and employees. Although employees rated their commitment to the farm and their interest in learning as high, based on turnover, there was an obvious disparity between reality and ideal employee

    2005-01-28

    There is a growing body of evidence linking health and well-being to key business issues. Despite this, corporate uptake of workplace health promotion programmes has been slow outside the USA. One possible reason for this is the lack of a generally available health risk measure that is quick and easy to administer and produces data that is rich enough to inform and direct subsequent employee health promotional interventions. We report on the development and validation of the health and well-being (HWB) assessment, a free to use health risk appraisal questionnaire that has been specifically developed for use in the corporate setting. The HWB assessment focuses upon modifiable health issues that directly impact upon business drivers. Development involved interviews with business leaders to ascertain their key areas of focus, scientific and general literature review to find evidence for health status having an impact upon these areas, and end user testing.Three UK-based organisations (insurance, telecommunications and consumer goods sectors) participated in the research. A total of 2224 employees completed the HWB assessment, the short-form 36 (SF-36) and the World Health Organisation Health and Work Performance questionnaire (WHO-HPQ) as part of the validation process. The HWB assessment is a twenty item questionnaire covering ten areas of health and well-being. Completion of the HWB assessment generates a global health risk score and ten sub-scores corresponding to the ten areas covered. It is easy to use and quick to complete (average completion time was eight minutes) and showed good internal consistency and test-retest reliability. Statistically significant correlations with similar SF-36 variables were observed. A significant negative correlation between HWB score and productivity decrement, as measured by the WHO-HPQ, was observed (r = -0.4). Individuals with HWB scores above the 25th percentile were more likely to achieve workplace productivity standards than

    The present study investigated the production of hydrogen (H{sub 2}) and ethanol from glucose in an Anaerobic Continuous Stirred Tank Reactor (ACSTR). Effects of hydraulic retention time (HRT) and pH on the preference of producing H{sub 2} and/or ethanol and other soluble metabolic products in an open anaerobic enriched culture were studied. Production rates of H{sub 2} and ethanol increased with the increase of biomass concentration. Open anaerobic fermentation was directed and managed through on-line pH control for the production of H{sub 2} or ethanol. Hydrogen was produced by ethanol and acetate-butyrate type fermentations. pH has strong effect on the H{sub 2} or ethanol production by changing fermentation pathways. ACSTR produced mainly ethanol at over pH 5.5 whereas highest H{sub 2} production was obtained at pH 5.0. pH 4.9 favored the lactate production and accumulation of lactate inhibited the biomass concentration in the reactor and the production of H{sub 2} and ethanol. The microbial community structure quickly responded to pH changes and the Clostridia dominated in ACSTR during the study. H{sub 2} production was maintained mainly by Clostridium butyricum whereas in the presence of Bacillus coagulans glucose oxidation was directed to lactate production. (author)

    Full Text Available Forty-three new hybrid bracharia lines were evaluated for forage accumulation and nutritive value in Northeast Thailand from 2006 to 2011 in experiments at 2 sites, using Mulato II hybrid brachiaria as a standard for comparison. The parameters evaluated were wet and dry season dry matter (DM accumulation, leaf:stem ratio, crude protein (CP concentration and fiber level [acid detergent fiber (ADF and neutral detergent fiber (NDF]. No lines consistently displayed superior dry season forage accumulation and leaf:stem ratio over Mulato II. In the wet seasons, 14 lines produced more DM than Mulato II but in only one wet season each. Mulato II produced forage with high leaf:stem ratio in all seasons. Many lines did have significantly higher CP concentrations and lower levels of ADF and NDF than Mulato II, but their forage accumulation and leaf:stem ratio were inferior. Four lines (BR02/1718, BR02/1752, BR02/1794 and BR02/0465 were granted Plant Variety Rights in 2011.Keywords: Cayman, Cobra, crude protein, dry matter yields, forage regrowth,  Mulato II.DOI: 10.17138/TGFT(383-93

    Full Text Available Tilapia is the second most widely cultivated species in the international scope, due to their fast growing and breeding capacity in captivity. Its biggest problem is the unpredictability of the productive performance of varieties in different environments and management types. For this reason, the productive performance of three lines: Oreochromis niloticus (N, red Oreochromis mossambicus (M and Rocky Mountain (R, cultured in five sites in two environments (Presses: Miguel de la Madrid and Miguel Aleman in the State of Oaxaca, Mexico was compared. Cages with dimensions between 18 and 48 m3 with stocking density of 7 to 28 fish m-3 were used. Feeding varied depending on the producers (1 to 3 portions a day/cage (300 to 1200 g of feed. Total length (TL, weight (P, survival (SUP and fillet yield (RF were evaluated in each genetic line. Results from physicochemical parameters of water, environments of culture and production efficiency of the strains indicated no significant differences, except for weight gain (g between sites of culture. However, it was considered that the differences were mainly due to handling during the culture, rather than the genetic line. Genetic lines showed similar performance (Tilapia R: LT 16.5 ± 3.1 cm, P 99.0± 46.6 g, 28 % RF, SUP 91.6 %. Tilapia N: LT 16.7 ± 3.7 cm, P 98.2 ± 40.9, RF 23 % SUP 86 %. Tilapia M: LT 15.4 ± 4.6 cm, P 100.1 ± 112.5 g, 30 % RF, SUP 91.6 %. Under the conditions evaluated, type of management could influence the efficiency of the culture more than the genetic line.

    The P genome of Agropyron Gaertn., a wild relative of wheat, contains an abundance of desirable genes that can be utilized as genetic resources to improve wheat. In this study, wheat - Aegilops cylindrica Host gametocidal chromosome 2C addition lines were crossed with wheat - Agropyron cristatum (L.) Gaertn. disomic addition line accession II-21 with alien recombinant chromosome (1.4)P. We successfully induced wheat - A. cristatum alien chromosomal translocations for the first time. The frequency of translocation in the progeny was 3.75%, which was detected by molecular markers and genomic in situ hybridization (GISH). The translocation chromosomes were identified by dual-color GISH /fluorescence in situ hybridization (FISH). The P genomic DNA was used as probe to detect the (1.4)P chromosome fragment, and pHvG39, pAs1, or pSc119.2 repeated sequences were used as probes to identify wheat translocated chromosomes. The results showed that six types of translocations were identified in the three wheat - A. cristatum alien translocation lines, including the whole arm or terminal portion of a (1.4)P chromosome. The (1.4)P chromosome fragments were translocated to wheat chromosomes 1B, 2B, 5B, and 3D. The breakpoints were located at the centromeres of 1B and 2B, the pericentric locations of 5BS, and the terminals of 5BL and 3DS. In addition, we obtained 12 addition-deletion lines that contained alien A. cristatum chromosome (1.4)P in wheat background. All of these wheat - A. cristatum alien translocation lines and addition-deletion lines would be valuable for identifying A. cristatum chromosome (1.4)P-related genes and providing genetic resources and new germplasm accessions for the genetic improvement of wheat. The specific molecular markers of A. cristatum (1.4)P chromosome have been developed and used to track the (1.4)P chromatin.

    1987-01-01

    Antigens present in the products released by the larval stage of schistosome (SRP-A) were shown to induce a strong cytotoxic and protective IgE response both in the rat and the monkey. T cell lines and clones specific for SRP-A or 26 kD antigens which are the main target of the cytotoxic IgE have been derived. The passive transfer of SRP-A specific T lymphocytes into infected rats led to an increase of the IgE response, conferring a significant level of protection to the rats. In coculture assays in vitro, these cell lines significantly enhanced the production of IgE by SRP-A sensitized rat spleen cells. This helper effect on the IgE response was confirmed with 26 kD T cell clone supernatants. Moreover, supernatants obtained after stimulation with phorbol myristate acetate were able to enhance the IgE production of a hybridoma B cell line (B48-14) producing a monoclonal IgE antibody, cytotoxic for the schistosomula.

    Antigens present in the products released by the larval stage of schistosome (SRP-A) were shown to induce a strong cytotoxic and protective IgE response both in the rat and the monkey. T cell lines and clones specific for SRP-A or 26 kD antigens which are the main target of the cytotoxic IgE have been derived. The passive transfer of SRP-A specific T lymphocytes into infected rats led to an increase of the IgE response, conferring a significant level of protection to the rats. In coculture assays in vitro, these cell lines significantly enhanced the production of IgE by SRP-A sensitized rat spleen cells. This helper effect on the IgE response was confirmed with 26 kD T cell clone supernatants. Moreover, supernatants obtained after stimulation with phorbol myristate acetate were able to enhance the IgE production of a hybridoma B cell line (B48-14) producing a monoclonal IgE antibody, cytotoxic for the schistosomula.

    We report the fabrication and characterization of double line waveguides directly written in tellurite and germanate glasses using a femtosecond laser delivering 30 μJ, 80 fs pulses at 4 kHz repetition rate. The double line waveguides produced presented internal losses inferior to 2.0 dB/cm. The output mode profile and the M2 measurements indicate multimodal guiding behavior. A better beam quality for the GeO2 - PbO waveguide was observed when compared with TeO2 - ZnO glass. Raman spectroscopy of the waveguides showed structural modification of the glassy network and indicates that a negative refractive index modification occurs at the focus of the laser beam, therefore allowing for light guiding in between two closely spaced laser written lines. The refractive index change at 632 nm is around 10-4, and the structural changes in the laser focal region of the writing, evaluated by Raman spectroscopy, corroborated our findings that these materials are potential candidates for optical waveguides and passive components. To the best of our knowledge, the two double line configuration demonstrated in the present work was not reported before for germanate or tellurite glasses.

    Although researchers have studied employee lateness empirically (e.g., S. Adler & J. Golan, 1981; C. W. Clegg, 1983), few have attempted to describe the punctual employee. In the present study, results of a discriminant analysis on employees in Israel indicated that a personality characteristic, time urgency, a subcomponent of Type A behavioral pattern, distinguished between punctual and late employees. Organizational commitment and age of employee's youngest child also distinguished between the groups.

    Among wheat gluten proteins, the α-type gliadins are the major responsible for celiac disease, an autoimmune disorder that affects about 1% of the world population. In fact, these proteins contain several toxic and immunogenic epitopes that trigger the onset of the disease. The α-type gliadins are a multigene family, encoded by genes located at the complex Gli-2 loci. Here, three bread wheat deletion lines (Gli-A2, Gli-D2 and Gli-A2/Gli-D2) at the Gli-2 loci were generated by the introgression in the bread wheat cultivar Pegaso of natural mutations, detected in different bread wheat cultivars. The molecular characterization of these lines allowed the isolation of 49 unique expressed genes coding α-type gliadins, that were assigned to each of the three Gli-2 loci. The number and the amount of α-type gliadin transcripts were drastically reduced in the deletion lines. In particular, the line Gli-A2/Gli-D2 contained only 12 active α-type gliadin genes (-75.6% respect to the cv. Pegaso) and a minor level of transcripts (-80% compared to cv. Pegaso). Compensatory pleiotropic effects were observed in the two other classes of gliadins (ω- and γ-gliadins) either at gene expression or protein levels. Although the comparative analysis of the deduced amino acid sequences highlighted the typical structural features of α-type gliadin proteins, substantial differences were displayed among the 49 proteins for the presence of toxic and immunogenic epitopes. The deletion line Gli-A2/Gli-D2 did not contain the 33-mer peptide, one of the major epitopes triggering the celiac disease, representing an interesting material to develop less "toxic" wheat varieties.

    Providing cost-contained comprehensive quality health care to maintain healthy and productive employees is a challenging problem for all employers. Using a representative panel of metropolitan employees, the author investigates the internal and external structure of employee satisfaction with company-sponsored health care plans. Employee satisfaction is differentiated into four meaningful groups of health care benefits, whereas its external structure is supported by the traditional satisfaction paradigms of expectation-disconfirmation, attribution, and equity. Despite negative disconfirmation, employees register sufficiently high health care satisfaction levels, which suggests some useful strategies that employers may consider implementing.
