    Full Text Available Objectives: This study aims to identify the effects of evaluation on teaching and discusses improvements in the work of the evaluation office. Methods: Teaching evaluation data from 2006 to 2009 was collected and analyzed. Additional surveys were conducted to collect the perceptions of students, faculty members, peer reviewers, deans and chairs about teaching evaluation. Results: Evaluation scores for more than half of faculty members increased, significantly more for junior compared with senior faculty, over the period of the study. Student attendance and satisfaction with elective courses increased after interventions identified by teaching evaluations. All participants believed that teaching evaluation had positive effects on teaching quality and classroom behavior. Seventy-three percent of faculty believed the evaluation helped to improve their teaching skills. Faculty perceptions of the helpfulness of teaching evaluation were related to the speed in which evaluations were reported, the quality of comments received, and the attitudes held by faculty towards evaluation. All the faculty members, chairs and deans read evaluation reports, and most of them believed the reports were helpful. Conclusions: Teaching evaluation at SMMU was perceived to improve both the teaching quality and classroom behavior. Faster feedback and higher quality comments are perceived to provide more help to faculty members.

    2009-12-01

    Full Text Available It is often difficult to provide students in introductory science courses with opportunities that mimic the investigative learning experience of doing research. This is particularly true in microbiology courses where advanced microscopy techniques are expensive and difficult to do. To that end, we developed three computer-based case studies around real-life scenarios. Our goals were to: (i improve students’ understanding of advanced microscopic techniques, (ii give students practice analyzing and interpreting data, and (iii model a scientific approach to how these techniques are applied to current issues in microbiology. Each case requires students to use references and interpret actual microscopic images, thus giving them a more realistic experience than we could previously provide. We analyzed student learning and perceptions to these case studies. After doing the case studies, students were more able to apply microscopic methods to a realistic problem, thus demonstrating an understanding of how the methods are used. Students appreciated the intellectual challenges presented by having to interpret and analyze actual microscopic images. This approach has allowed us to introduce new areas of content to our course and to stimulate critical thinking skills, a difficult task in a large introductory microbiology course.

    Full Text Available Theoretically, the ultimate benefits of health development projects are reflected as increased incomes or tangible improvements in quality of life. They will only be forth coming if services provided by project have more direct effect for those who use the services. However the effects of health programs might be direct or indirect so that they are difficult to be measured comparing with other sectors. The study team conducted a study on Benefit Monitoring and Evaluation (BME by using The Rural Health and Population Project (ADB Ill-Loan No.1299-lno as objective of the study. The study was conducted in the year 2000, however, the results of this study is relevant to be published due to it is difficult to find the references, which showed the experiences of the BME study in the health sector.

    1984-01-01

    An efficient 3-D geometry graphics software package which is suitable for advanced design studies was developed. The advanced design system is called GRADE--Graphics for Advanced Design. Efficiency and ease of use are gained by sacrificing flexibility in surface representation. The immediate options were either to continue development of GRADE or to acquire a commercially available system which would replace or complement GRADE. Test cases which would reveal the ability of each system to satisfy the requirements were developed. A scoring method which adequately captured the relative capabilities of the three systems was presented. While more complex multi-attribute decision methods could be used, the selected method provides all the needed information without being so complex that it is difficult to understand. If the value factors are modestly perturbed, system Z is a clear winner based on its overall capabilities. System Z is superior in two vital areas: surfacing and ease of interface with application programs.

  20. Organic dairy production systems in Pennsylvania: a case study evaluation.

    2007-08-01

    The current market demand and price for organic milk is encouraging dairy producers, particularly those on smaller farms, to consider organic production as a means for improving the economic viability of their operations. Organic production systems vary widely in scale, in practices, and across agroclimatic settings. Within this context, case studies of 4 actual organic dairy farms were used to characterize existing systems in Pennsylvania. Based on data from these farms, a whole-farm simulation model (Integrated Farm System Model) was used to compare 4 production systems representing organic grass, organic crop, conventional crop with grazing, and conventional confinement production. The performance of each of these systems was simulated over each year of 25 yr of central Pennsylvania weather data. Simulation results indicated that farm level accumulation of soil P and K may be a concern on organic farms that use poultry manure as a primary crop nutrient source, and that erosion and runoff loss of P may be of concern on organic farms producing annual crops because more tillage is required for weed control. Whole-farm budgets with prices that reflect recent conditions showed an economic advantage for organic over conventional production. A sensitivity analysis showed that this economic advantage depended on a higher milk price for producers of organic milk and was influenced by the difference in milk production maintained by herds using organic and conventional systems. Factors found to have little effect on the relative profitability of organic over conventional production included the differences between organic and conventional prices for seed, chemicals, forage, and animals and the overall costs or prices assumed for organic certification, machinery, pasture fencing, fuel, and labor. Thus, at the current organic milk price, relative to other prices, the case study organic production systems seem to provide an option for improving the economic viability of dairy

    Analytical usability evaluation methods (UEMs) can complement empirical evaluation of systems: for example, they can often be used earlier in design and can provide accounts of why users might experience difficulties, as well as what those difficulties are. However, their properties and value are only partially understood. One way to improve our understanding is by detailed comparisons using a single interface or system as a target for evaluation, but we need to look deeper than simple proble...

    Full Text Available Abstract Background The Ministry of Health and Medical Education in the Islamic Republic of Iran has undertaken a reform of its health system, in which-lower level managers are given new roles and responsibilities in a decentralized system. To support these efforts, a United Kingdom-based university was contracted by the World Health Organization to design a series of courses for health managers and trainers. This process was also intended to develop the capacity of the National Public Health Management Centre in Tabriz, Iran, to enable it to organize relevant short courses in health management on a continuing basis. A total of seven short training courses were implemented, three in the United Kingdom and four in Tabriz, with 35 participants. A detailed evaluation of the courses was undertaken to guide future development of the training programmes. Methods The Kirkpatrick framework for evaluation of training was used to measure participants' reactions, learning, application to the job, and to a lesser extent, organizational impact. Particular emphasis was put on application of learning to the participants' job. A structured questionnaire was administered to 23 participants, out of 35, between one and 13 months after they had attended the courses. Respondents, like the training course participants, were predominantly from provincial universities, with both health system and academic responsibilities. Interviews with key informants and ex-trainees provided supplemental information, especially on organizational impact. Results Participants' preferred interactive methods for learning about health planning and management. They found the course content to be relevant, but with an overemphasis on theory compared to practical, locally-specific information. In terms of application of learning to their jobs, participants found specific information and skills to be most useful, such as health systems research and group work/problem solving. The least

    It is argued that to evaluate an information source (e.g., a Wikipedia article), it is necessary to relate the content of that source to an interpretation of the state of knowledge at the research front (which is typically developing dynamically). In the research literature, there is a controversy...... about the effect of screening programs for breast cancer. This controversy is used to compare the value of Wikipedia with Encyclopedia Britannica and two Danish encyclopedias as information sources. It is argued that this method of examining information sources is preferable to other methods which have...

  12. Evaluation of energy efficiency policy instruments effectiveness : case study Croatia

    International Nuclear Information System (INIS)

    This paper proposed a theoretical basis for evaluating energy efficiency policy in the Republic of Croatia and corroborated it with the analysis of energy efficiency market development and transformation. The current status of the market was evaluated and policy instruments were adapted to achieve optimal results. In particular, the energy efficiency market in Croatia was discussed in terms of micro and macro environment factors that influence policy making processes and the choice of policy instruments. The macro environment for energy efficiency market in Croatia is the process of European Union pre-integration with all related national and international legislation, political and economical factors and potential to use financial funds. The micro environment consists of government institutions, local financing institutions and a range of market players on the supply and demand side. Energy efficiency is the most powerful and cost-effective way for achieving goals of sustainable development. Policy instruments developed to improve energy efficiency are oriented towards a cleaner environment, better standard of living, more competitive industry and improved security of energy supply. Energy efficiency is much harder to implement and requires policy interventions. In response to recent trends in the energy sector, such as deregulation and open competition, policy measures aimed at improving energy efficiency should shift from an end-users oriented approach towards a whole market approach. The optimal policy instruments mix should be designed to meet defined targets. However, market dynamics must be taken into consideration. 9 refs., 4 figs

    The aim of this retrospective study was to report frequency of sporadic odontogenic keratocysts (sOKC) according to the age and gender, as well as location (mandible, maxilla, soft tissues, and maxillary sinus). Four hundred and twenty nine sOKC confirmed pathohistologically in a period from 1965-1998 were included in this study. The average age of patients with sOKC was 43.11 (age range 10-91), in males 42.06 and in females 44.72 years. More frequently sOKC were found in males (60.61%) in comparison to the females (39.39%). Therefore, ratio between males and females was 1.5:1. Diagnosis of sOKC is usually established in patients aged 21-30 (18.88%), in males usually aged between 21-30 (23.46%), and in females aged between 11-20 (18.93%). sOKC are more frequent in males according to the age groups, except between age 61-70 where sOKC were more frequent in females. Most frequently, sOKC occurred in the mandible 70.16%, 12.35% of sOKC were found in the maxilla, 12.82% in soft tissues and 4.66% in the maxillary sinuses. PMID:12674852

    Rivers are one of the most environmentally vulnerable sources for contamination. Since the rivers pass through the cities, industrial and agricultural centers, these have been considered as place to dispose the sewages. This issue is more important when the river is one of the main sources of water supplying for drinking, agricultural and industrial utilizations. The goal of the present study was assessing the physicochemical characteristics of the Tireh River water. The Tireh River is the main river in the Karkheh catchment in the Iran. To this end, 14 sampling stations for measuring the physicochemical properties of Tireh River along the two main cities (Borujerd and Dorud) were measured. The results showed that (except SO4) Mg, Ca and other anions and cations have concentrations under WHO standard limitation. Almost all samples have suitable conditions for drinking with regard to the WHO standard and in comparison with agricultural standard (FAO Standard), and the potential of water is suitable for irrigation purposes. According to Wilcox diagram, 78 % of samples were at the C3-S1 and 21.5 % were at C2-S1 classes. The piper diagram shows that most of samples are bicarbonate and calcic facies.

  5. A study on nondestructive evaluation techniques for composite motors cases using circumferential waves

    International Nuclear Information System (INIS)

    For structural integrity evaluation of composite rocket motor cases, acoustic emission (AE) during hydroproof test is currently used. For the suitable performance of this test, it is very important to determine the optimal component of elastic waves to be monitored. In this study, the optimal component of circumferential wave that propagate in the circumferential direction of the composite motor case has been determined experimentally. Then its potential to be served as a robust tool for nondestructive evaluation of composite motor cases was demonstrated by investigating the initial performances for flaw detection and AE source location.

    2016-07-01

    Nursing education is challenged to prepare students for complex healthcare needs through the integration of teamwork and informatics. Technology has become an important teaching tool in the blended classroom to enhance group based learning experiences. Faculty evaluation of classroom technologies is imperative prior to adoption. Few studies have directly compared various technologies and their impact on student satisfaction and learning. The purpose of this study was to evaluate technology enhanced teaching methods on the learning and satisfaction of graduate students in an advanced pharmacology class using an unfolding case study. After IRB approval, students were randomly assigned to one of three groups: blogging group, wiki group or webinar group. Students completed the evolving case study using the assigned interactive technology. Student names were removed from the case studies. Faculty evaluated the case study using a rubric, while blinded to the assigned technology method used. No significant difference was found on case study grades, the range of grades on the assignment demonstrated little differences between the methods used. Students indicated an overall positive impact related to networking and collaboration on a satisfaction survey. Impact of technology methods needs to be explored in other areas of graduate nursing education. PMID:27428697

  16. Evaluating Pillar Industry's Transformation Capability: A Case Study of Two Chinese Steel-Based Cities.

    Directory of Open Access Journals (Sweden)

    Zhidong Li

    Full Text Available Many steel-based cities in China were established between the 1950s and 1960s. After more than half a century of development and boom, these cities are starting to decline and industrial transformation is urgently needed. This paper focuses on evaluating the transformation capability of resource-based cities building an evaluation model. Using Text Mining and the Document Explorer technique as a way of extracting text features, the 200 most frequently used words are derived from 100 publications related to steel- and other resource-based cities. The Expert Evaluation Method (EEM and Analytic Hierarchy Process (AHP techniques are then applied to select 53 indicators, determine their weights and establish an index system for evaluating the transformation capability of the pillar industry of China's steel-based cities. Using real data and expert reviews, the improved Fuzzy Relation Matrix (FRM method is applied to two case studies in China, namely Panzhihua and Daye, and the evaluation model is developed using Fuzzy Comprehensive Evaluation (FCE. The cities' abilities to carry out industrial transformation are evaluated with concerns expressed for the case of Daye. The findings have policy implications for the potential and required industrial transformation in the two selected cities and other resource-based towns.

    2014-05-01

    Report writing is an important employability skill for Engineers and Technologists, and this case study describes how a Technology degree module took a novel approach to developing students' report writing skills. Students learned how to use a criterion-referenced critical evaluation framework for reports and other technological documents. They were given opportunities to practise using the framework both through exemplars and through evaluating the work of their peers. They also carried out self-assessment. The authors' analysis of this novel approach shows that most students responded well to it and benefited from it. Lessons are drawn from this work for others who wish to improve their students' report writing skills.

  1. An Orchestrating Evaluation of Complex Educational Technologies: a Case Study of a CSCL System

    Directory of Open Access Journals (Sweden)

    Luis P. Prieto

    2014-06-01

    Full Text Available As digital technologies permeate every aspect of our lives, the complexity of the educational settings, and of the technological support we use within them, unceasingly rises. This increased complexity, along with the need for educational practitioners to apply such technologies within multi-constraint authentic settings, has given rise to the notion of technology-enhanced learning practice as “orchestration of learning”. However, at the same time, the complexity involved in evaluating the benefits of such educational technologies has also increased, prompting questions about the way evaluators can cope with the different places, technologies, informants and issues involved in their evaluation activity. By proposing the notion of “orchestrating evaluation”, this paper tries to reconcile the often disparate “front office accounts” of research publications and the “shop floor practice” of evaluation of educational technology, through the case study of evaluating a system to help teachers in coordinating computer-supported collaborative learning (CSCL scenarios. We reuse an internationally-evaluated conceptual framework of “orchestration aspects” (design, management, adaptation, pragmatism, etc. to structure the case‟s narrative, showing how the original evaluation questions and methods were modulated in the face of the multiple (authentic evaluation setting constraints.

  3. A real options-based CCS investment evaluation model: Case study of China's power generation sector

    International Nuclear Information System (INIS)

    Highlights: → This paper establishes a carbon captures and storage (CCS) investment evaluation model. → The model is based on real options theory and solved by the Least Squares Monte Carlo (LSM) method. → China is taken as a case study to evaluate the effects of regulations on CCS investment. → The findings show that the current investment risk of CCS is high, climate policy having the greatest impact on CCS development. -- Abstract: This paper establishes a carbon capture and storage (CCS) investment evaluation model based on real options theory considering uncertainties from the existing thermal power generating cost, carbon price, thermal power with CCS generating cost, and investment in CCS technology deployment. The model aims to evaluate the value of the cost saving effect and amount of CO2 emission reduction through investing in newly-built thermal power with CCS technology to replace existing thermal power in a given period from the perspective of power generation enterprises. The model is solved by the Least Squares Monte Carlo (LSM) method. Since the model could be used as a policy analysis tool, China is taken as a case study to evaluate the effects of regulations on CCS investment through scenario analysis. The findings show that the current investment risk of CCS is high, climate policy having the greatest impact on CCS development. Thus, there is an important trade off for policy makers between reducing greenhouse gas emissions and protecting the interests of power generation enterprises. The research presented would be useful for CCS technology evaluation and related policy-making.

    Walker, Iain S.; McWiliams, Jennifer A.; Konopacki, Steven J.

    2003-09-01

    This case study focusing on a residence in northern California was undertaken as a demonstration of the potential of a systems approach to HVAC retrofits. The systems approach means that other retrofits that can affect the HVAC system are also considered. For example, added building envelope insulation reduces building loads so that smaller capacity HVAC system can be used. Secondly, we wanted to examine the practical issues and interactions with contractors and code officials required to accomplish the systems approach because it represents a departure from current practice. We identified problems in the processes of communication and installation of the retrofit that led to compromises in the final energy efficiency of the HVAC system. These issues must be overcome in order for HVAC retrofits to deliver the increased performance that they promise. The experience gained in this case study was used to optimize best practices guidelines for contractors (Walker 2003) that include building diagnostics and checklists as tools to assist in ensuring the energy efficiency of ''house as a system'' HVAC retrofits. The best practices guidelines proved to be an excellent tool for evaluating the eight existing homes in this study, and we received positive feedback from many potential users who reviewed and used them. In addition, we were able to substantially improve the energy efficiency of the retrofitted case study house by adding envelope insulation, a more efficient furnace and air conditioner, an economizer and by reducing duct leakage.

    Cloud-resolving models (CRMs) provide an effective linkage in terms of parameters and scales between observations and the parametric treatments of clouds in global climate models (GCMs). They also represent the best understanding of the physical processes acting to determine cloud system lifecycle. The goal of this project is to improve state-of-the-art CRMs used for studies of cirrus clouds and to establish a relative calibration with GCMs through comparisons among CRMs, single column model (SCM) versions of the GCMs, and observations. This project will compare and evaluate a variety of CRMs and SCMs, under the auspices of the GEWEX Cloud Systems Study (GCSS) Working Group on Cirrus Cloud Systems (WG2), using ARM data acquired at the Southern Great Plains (SGP) site. This poster will report on progress in developing a suitable WG2 case study data set based on the September 26, 1996 ARM IOP case - the Hurricane Nora outflow case. The environmental data (input) will be described as well as the wealth of validating cloud observations. We plan to also show results of preliminary simulations. The science questions to be addressed derive significantly from results of the GCSS WG2 cloud model comparison projects, which will be briefly summarized.

  9. Critical evaluation of financial supporting schemes for wind-based projects: Case study Greece

    International Nuclear Information System (INIS)

    After a long stagnating period during the second half of the 1990s, the market of wind energy in Greece was described by remarkable but unstable growth rates that resulted in the operation of 1 GW of wind power by the end of 2009. Still though, penetration of wind energy is not the one anticipated. On the other hand, national targets regarding the Renewable Energy Sources' (RES) contribution and existence of excellent wind potential areas across Greece challenge new wind energy investments. Acknowledging the unsteady development rates of wind power in Greece, efficiency of the State support mechanisms is currently investigated. Based on an analytical evaluation model, the investigation undertaken is extended to provide a detailed cost-benefit analysis of several wind energy case studies, including mainland and island applications as well as comparison with both conventional power stations and photovoltaic plants. For this purpose, the financial support provided by the State is directly compared with benefits accruing from the operation of wind parks, considering also the avoidance of social costs deriving from thermal power stations. Based on the results obtained, the beneficial characteristics of wind energy applications for the Greek society are clearly demonstrated, especially in the case of non-interconnected island grids. - Research highlights: → Since the mid-1990s, growth of wind power capacity in Greece has been unstable. → As a result, integration of wind energy is not the one anticipated. → Considering the situation, efficiency of State support mechanisms is evaluated. → An analytical cost-benefit model is developed and applied to various case studies. → Benefits from wind energy, especially in island regions, are designated.

    Traditional case-control studies provide a powerful and efficient method for evaluation of association between candidate genes and disease. The sampling of cases from multiplex pedigrees, rather than from a catchment area, can increase the likelihood that genetic cases are selected. However, use of all the related cases without accounting for their biological relationship can increase the type I error rate of the statistical test. To overcome this problem, we present an analysis method that i...

    2009-02-01

    Full Text Available Recent field studies have found large discrepancies in the measured vs. modeled SOA mass loadings in both urban and regional polluted atmospheres. The reasons for these large differences are unclear. Here we revisit a case study of SOA formation in Mexico City described by Volkamer et al. (2006, during a photochemically active period when the impact of regional biomass burning is minor or negligible, and show that the observed increase in OA/ΔCO is consistent with results from several groups during MILAGRO 2006. Then we use the case study to evaluate three new SOA models: 1 the update of aromatic SOA yields from recent chamber experiments (Ng et al., 2007; 2 the formation of SOA from glyoxal (Volkamer et al., 2007a; and 3 the formation of SOA from primary semivolatile and intermediate volatility species (P-S/IVOC (Robinson et al., 2007. We also evaluate the effect of reduced partitioning of SOA into POA (Song et al., 2007. Traditional SOA precursors (mainly aromatics by themselves still fail to produce enough SOA to match the observations by a factor of 7. The new low-NOx aromatic pathways with very high SOA yields make a very small contribution in this high-NOx urban environment as the RO2.+NO reaction dominates the fate of the RO2. radicals. Glyoxal contributes several μg m−3 to SOA formation, with similar timing as the measurements. P-S/IVOC are estimated from equilibrium with emitted POA, and introduce a large amount of gas-phase oxidizable carbon that was not in models before. With the formulation in Robinson et al. (2007 these species have a high SOA yield, and this mechanism can close the gap in SOA mass between measurements and models in our case study. However the volatility of SOA produced in the model is too high and the O/C ratio is lower than observations. Glyoxal SOA helps to bring the O/C ratio of predicted and observed SOA into better agreement. The

    2009-12-01

    Full Text Available The undergraduate science programme was launched at the Indira Gandhi National Open University (IGNOU in 1991-92 with an enrolment of 1,210 students. The programme was well received, and enrolments increased over the years. However, the success rates have not kept pace with enrolment.In this paper, the authors report the results of an evaluation of the undergraduate Physics programme at IGNOU. The evaluation, the first of its type for this programme, adapted the major tenets of the CIPP model. The findings are based on the responses from a randomly chosen sample of 509 learners across India. The methods employed for the study include records, document, and database analysis, surveys, and case studies.Although the University has enhanced access to higher science education, the attrition rate is high (73%, and the success rate is low. The authors recommend that the University review and reorient its strategies for providing good quality, learner-centred higher education in science subjects. The programme should address the concerns of the learners about the effectiveness of the student support systems, the difficulty level, and the learner-friendliness of study materials with the goal of achieving long-term sustainability while maintaining parity with the conventional system. The need for improving the presentation of the courses and simplifying the mathematical details is emphasised.

    Cloud-resolving models (CRMs) are being increasingly used to develop parametric treatments of clouds and related processes for use in global climate models (GCMs). CRMs represent the integrated knowledge of the physical processes acting to determine cloud system lifecycle and are well matched to typical observational data in terms of physical parameters/measurables and scale-resolved physical processes. Thus, they are suitable for direct comparison to field observations for model validation and improvement. The goal of this project is to improve state-of-the-art CRMs used for studies of cirrus clouds and to establish a relative calibration with GCMs through comparisons among CRMs, single column model (SCM) versions of the GCMs, and observations. The objective is to compare and evaluate a variety of CRMs and SCMs, under the auspices of the GEWEX Cloud Systems Study (GCSS) Working Group on Cirrus Cloud Systems (WG2), using ARM data acquired at the Southern Great Plains (SGP) site.

    Saliceti, Jose A.

    The purpose of this qualitative case study was to explore and identify strategies that may potentially remedy operational test and evaluation procedures used to evaluate Unmanned Aircraft Systems (UAS) technology. The sample for analysis consisted of organizations testing and evaluating UASs (e.g., U.S. Air Force, U.S. Navy, U.S. Army, U.S. Marine Corps, U.S. Coast Guard, and Customs Border Protection). A purposeful sampling technique was used to select 15 subject matter experts in the field of operational test and evaluation of UASs. A questionnaire was provided to participants to construct a descriptive and robust research. Analysis of responses revealed themes related to each research question. Findings revealed operational testers utilized requirements documents to extrapolate measures for testing UAS technology and develop critical operational issues. The requirements documents were (a) developed without the contribution of stakeholders and operational testers, (b) developed with vague or unrealistic measures, and (c) developed without a systematic method to derive requirements from mission tasks. Four approaches are recommended to develop testable operational requirements and assist operational testers: (a) use a mission task analysis tool to derive requirements for mission essential tasks for the system, (b) exercise collaboration among stakeholders and testers to ensure testable operational requirements based on mission tasks, (c) ensure testable measures are used in requirements documents, and (d) create a repository list of critical operational issues by mission areas. The preparation of operational test and evaluation processes for UAS technology is not uniform across testers. The processes in place are not standardized, thus test plan preparation and reporting are different among participants. A standard method to prepare and report UAS technology should be used when preparing and reporting on UAS technology. Using a systematic process, such as mission

    Background: Imbalances between the oxidant-antioxidant status have been implicated in the pathogenesis of several diseases, including cancer. The aim of this study was to evaluate the extent of lipid peroxidation and antioxidants in the tissue samples of oral squamous cell carcinoma (OSCC) patients of different clinical stages in comparison with the healthy controls. Materials and Methods: A case-control study was designed with 20 new histopathologically proven oral carcinoma patients and an equal number of age, sex, and tobacco chewing habit matched healthy subjects. Their tissue samples were subjected to evaluation of lipid peroxidation product and antioxidant enzymes, namely, superoxide dismutase (SOD), catalase (CAT), reduced glutathione (GSH), and glutathione peroxidase (GPx) using spectrophotometric methods. The data are expressed as mean ± standard deviation. The statistical comparisons between the study groups were performed by independent Student's unpaired t-test and one-way analysis of variance. Post-hoc analysis was performed for within study group comparisons. Karl Pearson correlation was performed for the biochemical parameters within the group and between the groups. For statistically significant correlations, simple linear regression was performed using SPSS (α=0.05). Results: Significant reduction in lipid peroxidation (P < 0.001) SOD and CAT (P < 0.001) was observed in the tissue of OSCC patients as compared with the healthy controls. On the other hand, reduced GSH and GPx were significantly increased in tumor samples. Conclusion: Reduced lipid peroxidation and increased activity of reduced GSH and GPx provides the suitable environment for the local growth and invasion of the tumor and metastasis in the later stages. Among the antioxidant enzymes, GSH reductase appears to have a profound role in carcinogenesis and thus it can be considered as potential prognostic marker. PMID:27076834

    Full Text Available This article examines the relationship of society and architecture under the context of participative approaches in design processes. Participation methodologies are described as democratic enterprises in design process and user participation is a notion which can be realized by the collaboration of designer – city dweller (user – local authorities. In this study the demand of user participation in contemporary life-style is emphasized and different participation methods are assessed together. Participative approaches strengthen the relations between society and architecture in spatial organizations. In this context, city dwellers (society may have the right to have place in designing their environment by the contemporary participation methods and media. User participation approaches gained different dimensions with parallel to the changing of world. In the article, new understandings of user participation in design process are re-evaluated with historical and contemporary epochs. In this study, contemporary participation models will be analyzed by the help of theoretic postulations. Then the issue will be discussed in concern to Istanbul. Relation between city and city dweller in Istanbul will be introduced by a "case study in Levent" (globally developing region. Results of public survey in Levent regarding user participation will be presented. Article concludes with a participation proposal for Levent which discusses the methods of participation in pilot region and the social Dynamics of city-dwellers in Levent.

    Full Text Available The toxic chemical and heavy metals within wastewater can cause serious adverse impacts on human health. Health risk assessment (HRA is an effective tool for supporting decision-making and corrective actions in water quality management. HRA can also help people understand the water quality and quantify the adverse effects of pollutants on human health. Due to the imprecision of data, measurement error and limited available information, uncertainty is inevitable in the HRA process. The purpose of this study is to integrate statistical and probabilistic methods to deal with censored and limited numbers of input data to improve the reliability of the non-cancer HRA of dermal contact exposure to contaminated river water by considering uncertainty. A case study in the Kelligrews River in St. John’s, Canada, was conducted to demonstrate the feasibility and capacity of the proposed approach. Five heavy metals were selected to evaluate the risk level, including arsenic, molybdenum, zinc, uranium and manganese. The results showed that the probability of the total hazard index of dermal exposure exceeding 1 is very low, and there is no obvious evidence of risk in the study area.

    The Generation IV (GEN IV) International Forum (GIF) Proliferation Resistance and Physical Protection Working Group (PRPP WG) was established in December, 2002, as one of the crosscut groups under GIF, in order to develop a methodology for evaluating PR and PP of potential GEN IV options. The group currently consists of the experts from the U.S. national laboratories and universities, from Canada, France, Republic of Korea (ROK), Japan, the International Atomic Energy Agency (IAEA), and European Union(EU). The present report, published in Oct. 2009, was used as a supporting study for development of the evaluation methodology for proliferation resistance and physical protection of GEN IV nuclear energy systems. The present report is summarizing the case study of the PR and PP evaluation of Example Sodium Fast Reactor (ESFR), a hypothetical nuclear energy system consisting of nine main system elements, and it provides for designers the practical experience of applying the PR and PP evaluation methodology to a nuclear energy system. The development of the future nuclear fuel cycle system with sufficient PR and PP features is a crucial task in Japan, and the demonstration and explanation about its effectiveness to the domestic and international society will be required. With the usefulness the present report for such purposes, it was translated and published here as a Japanese-language edition with the concurrence of the OECD-NEA. The original report in English language can be downloaded at the OECD-NEA website.

    Full Text Available Abstract Background Normal tension glaucoma is a major subtype of glaucoma, associated with intraocular pressures that are within the statistically normal range of the population. Monogenic forms following classical inheritance patterns are rare in this glaucoma subtype. Instead, multigenic inheritance is proposed for the majority of cases. The present study tested common sequence variants in candidate genes for association with normal tension glaucoma in the German population. Methods Ninety-eight SNPs were selected to tag the common genetic variation in nine genes, namely OPTN (optineurin, RDX (radixin, SNX16 (sorting nexin 16, OPA1 (optic atrophy 1, MFN1 (mitofusin 1, MFN2 (mitofusin 2, PARL (presenilin associated, rhomboid-like, SOD2 (superoxide dismutase 2, mitochondrial and CYP1B1 (cytochrome P450, family 1, subfamily B, polypeptide 1. These SNPs were genotyped in 285 cases and 282 fully evaluated matched controls. Statistical analyses comprised single polymorphism association as well as haplogroup based association testing. Results Results suggested that genetic variation in five of the candidate genes (RDX, SNX16, OPA1, SOD2 and CYP1B1 is unlikely to confer major risk to develop normal tension glaucoma in the German population. In contrast, we observed a trend towards association of single SNPs in OPTN, MFN1, MFN2 and PARL. The SNPs of OPTN, MFN2 and PARL were further analysed by multimarker haplotype-based association testing. We identified a risk haplotype being more frequent in patients and a vice versa situation for the complementary protective haplotype in each of the three genes. Conclusion Common variants of OPTN, PARL, MFN1 and MFN2 should be analysed in other cohorts to confirm their involvement in normal tension glaucoma.

    2015-04-01

    In the last years studies concerning the triggering and the run-out susceptibility for different kind of landslides have become more and more precise. In the most of the cases the methodological approach involve the production of detailed thematic maps (at least 1:5000 scale) which represent a very useful tool for territorial planning, especially in urbanized areas. More recently these researches were accompanied by the growth of other studies dealing with landslide magnitude evaluation (especially in terms of volume and velocity estimate). In this paper the results of a flow-type landslides magnitude evaluation are presented. The study area is located in Southern Italy and is very wide (1,500 square kilometres) including all the Campania region. In this context flow type landslides represent the most frequent instabilities as shown by the large number of victims and the huge economic damage caused in the last few centuries. These shallow landslides involve thin cohesionless, unsaturated pyroclastic soils found over steep slopes around Somma-Vesuvio and Phlegrean district, affecting a wide area where over 100 towns are located. Since the potential volume of flow-type landslides is a measure of event magnitude we propose to estimate the potential volume at the scale of slope or basin for about 90 municipalities affecting 850 hierarchized drainage basins and 900 regular slopes. An empirical approach recently proposed in literature (De Falco et al., 2012), allows to estimate the volume of the pyroclastic cover that can be displaced along the slope. The method derives from the interpretation of numerous geological and geomorphological data gathered from a vast amount of case histories on landslides in volcanic and carbonatic contexts and it is based on determining the thickness of the pyroclastic cover and the width of the detachment and erosion-transport zone. Thickness can be evaluated with a good degree of approximation since, in these landslides, the failure

    Full Text Available Landscape analysis is regarded as a new tool for monitoring and judging land use patterns in terms of sustainability of human activity systems at local level. A case study of evaluation for sustainability based on habitat patch diversity in an ecoregion of Central Italy is presented. In this region, ongoing land use patterns reflect both historical adaptation to local environmental constraints and positive, social-oriented management. More protective land use patterns are mostly widespread in fragile physiographic conditions like those of the mountain areas, where woodland, shrub, and grassland patches are larger and cover more than 90% of the land. This situation is regarded as a positive outcome of the traditional public ownership regime, because public lands amount to more than 70% in the mountain areas. The hilly areas, where public property drops to 28%, presents landscape metrics showing a well balanced situation between agricultural land use and protective native woods and grasslands, which provides a finegrained and harmonious Mediterranean landscape. In the low-land areas, with anthropic pressure and more favourable conditions for crop productivity, there is much more agricultural land, even if some mitigation in terms of biodiversity maintenance is offered by the presence of hedgerow ecotones. In these areas, landscape analysis is not able to supply meaningful information about cropping system design and practices which can maintain a sustainable level of soil fertility and quality of natural resources and processes, and further analysis at cropping system level should be carried out.

  10. Sensitivity of inferred climate model skill to evaluation decisions: a case study using CMIP5 evapotranspiration

    International Nuclear Information System (INIS)

    Confrontation of climate models with observationally-based reference datasets is widespread and integral to model development. These comparisons yield skill metrics quantifying the mismatch between simulated and reference values and also involve analyst choices, or meta-parameters, in structuring the analysis. Here, we systematically vary five such meta-parameters (reference dataset, spatial resolution, regridding approach, land mask, and time period) in evaluating evapotranspiration (ET) from eight CMIP5 models in a factorial design that yields 68 700 intercomparisons. The results show that while model–data comparisons can provide some feedback on overall model performance, model ranks are ambiguous and inferred model skill and rank are highly sensitive to the choice of meta-parameters for all models. This suggests that model skill and rank are best represented probabilistically rather than as scalar values. For this case study, the choice of reference dataset is found to have a dominant influence on inferred model skill, even larger than the choice of model itself. This is primarily due to large differences between reference datasets, indicating that further work in developing a community-accepted standard ET reference dataset is crucial in order to decrease ambiguity in model skill.

    Full Text Available As Maloney and Ward (1973 noted thirty eight years ago, “determining what the population knows regarding ecology, the environment and pollution; how they feel about it; what commitments they are willing to make and what commitments they do make are necessary steps that must be made before adopting any strategy that modifies behaviour and habits”. Taking into account that Romania is facing a great challenge to bring its waste management system in line with EU Directives and the key role of education in this process, the paper aims to explore through a questionnaire based survey: (1 the level of knowledge and awareness regarding municipal waste among students, their attitudes and willingness to act in waste related activities, (2 if there are significant differences regarding students awareness, knowledge and concern according to their gender, age, affiliation (faculty or job status. The paper is structured in four parts, namely: introduction, research methodology, results analysis and conclusions. The findings of this research study showed that the majority of students are generally aware of waste problems. It is important to note, however, that many respondents called for more information, frequent updates and reminders about waste management practices. Pro-environmental and recycling attitudes were shown to be generally positive among students from BAES. Used in the right way such findings might be essential in achieving the overall goal of improving waste management systems, whether it is a recycling scheme, composting scheme or refers to the improvement of environmental awareness process.

    The purpose of this study was twofold. First, to methodologically examine the use of three types of focus groups 1), traditional face-to face, 2), online video and audio, and 3) online text only. Second, to examine the impact of academic intervention attempts offered by university and department support services. Methodologically, the three types of focus groups were compared in terms of ease of use, comfort, richness of data and ethical considerations. Contextually, support services for a general chemistry course taken primarily by new students were examined using an evaluation method involving effort, monitoring, process, component and treatment specification types of implementation. For this research, fourteen students enrolled in the general chemistry course at Rocky Mountain University in fall term 2014 participated in one of the three types of focus groups to discuss support services for the course. Since the increase of technological advances in the late twentieth century, the use of electronic focus groups has been viewed as a viable alternative to traditional in-person meetings. However, different methods within a methodology might produce different results for both students and researchers. This study inspected differences in ease of use for participants and the researcher, comfort in terms of using technology and in discussing academic issues and support services, richness of the data, and ethical issues surrounding privacy and confidentiality. For this case study, methodological findings were that in-person groups still had relevance in this age of advanced technology. Audio-video groups were more limited than in-person groups in terms of interaction and administration, while text-only groups were easiest to transcribe, but seemed to be the most limited in terms of all other aspects of the research. Finally, ethical concerns were not considered important by members in any group; therefore, it is incumbent on the researcher to provide the best ethical

    This paper reports a pilot study of Context Evaluation using a self-developed questionnaire distributed among engineering undergraduates at a university under study. The study aims to validate the self-developed questionnaires used in the Context evaluation, a component in the CIPP Model. The Context evaluation assesses background information for needs, assets, problems and opportunities relevant to beneficiaries of the study in a defined environment. Through the questionnaire, background information for the assessment of needs, assets and problems related to the engineering undergraduates' perceptions on the teaching and learning of technical oral presentation skills was collected and analysed. The questionnaire was developed using 5-points Likert scale to measure the constructs under study. They were distributed to 100 respondents with 79 returned. The respondents consisted of engineering undergraduates studied at various faculties at one technical university in Malaysia. The descriptive analysis of data for each item which makes up the construct for Context evaluation is found to be high. This implied that engineering undergraduates showed high interest in teaching and learning of technical oral presentation skills, thus their needs are met. Also, they agreed that assets and facilities are conducive to their learning. In conclusion, the context evaluation involving needs and assets factors are both considerably important; their needs are met and the assets and facilities do support their technical oral presentation skills learning experience.

    For sites with a contaminant source located in the vadose zone, the nature and extent of groundwater contaminant plumes are a function of the contaminant flux from the vadose zone to groundwater. Especially for thick vadose zones, transport may be relatively slow making it difficult to directly measure contaminant flux. An integrated assessment approach, supported by site characterization and monitoring data, is presented to explain current vadose zone contaminant distributions and to estimate future contaminant flux to groundwater in support of remediation decisions. The U.S. Department of Energy Hanford Site (WA, USA) SX Tank Farm was used as a case study because of a large existing contaminant inventory in its deep vadose zone, the presence of a limited-extent groundwater plume, and the relatively large amount of available data for the site. A predictive quantitative analysis was applied to refine a baseline conceptual model through the completion of a series of targeted simulations. The analysis revealed that site recharge is the most important flux-controlling process for future contaminant flux. Tank leak characteristics and subsurface heterogeneities appear to have a limited effect on long-term contaminant flux into groundwater. The occurrence of the current technetium-99 groundwater plume was explained by taking into account a considerable historical water-line leak adjacent to one of the tanks. The analysis further indicates that the vast majority of technetium-99 is expected to migrate into the groundwater during the next century. The approach provides a template for use in evaluating contaminant flux to groundwater using existing site data and has elements that are relevant to other disposal sites with a thick vadose zone.

    2013-06-01

    Full Text Available A large number of projects failed because of concentrating on developing new software. The Main drawbacks of new software development are more costly, and need maintenance. Reuse is solution of these problems that caused the widespread usage of object oriented (OO development. Object oriented development is the backbone of component-based development (CBD. CBD facilitates reuse of the existing components (by customizing with the new ones. Main advantages of reusable components are more reliable, saved time and reduced cost. CBD approach is different from traditional/new software development. Several models have been proposed for traditional software development such as Waterfall, Rapid Application Development (RAD, Evolutionary, Rational Unified Process (RUP and agile. Whereas the popular CBD models, for customized development, are V, Y, Umbrella and W. Almost all software development companies, both the new software and customized software have to be developed. Therefore majority of the software development companies face problem to select and implement an appropriate process model for the both kinds of developments. To address this problem, the existing RUP and CBD models do work to some extent but the authors intend to propose an extended CBD model that it equally offers its benefits for new and customized developments. The experimental data is taken from a case study to develop IP Multimedia Sub System (IMS-based examination application using iPhone to evaluate the proposed model. The results provide evidence that the extended CBD model can be equally beneficial for the development of both new and customization components for IMS-based applications.

    2015-10-01

    The main role of a waste management plan is to define which is the combination of waste management strategies and method needed to collect and manage the waste in such a way to ensure a given set of targets is reached. Objectives have to be sustainable and realistic, consistent with the environmental policies and regulations and monitored to verify the progressive achievement of the given targets. To get the aim, the setting up and quantification of indicators can allow the measurement of efficiency of a waste management system. The quantification of efficiency indicators requires the developing of a material flow analysis over the system boundary, from waste collection to secondary materials selling, processing and disposal. The material flow analysis has been carried out with reference to a case study for which a reliable, time- and site-specific database was available. The material flow analysis allowed the evaluation of the amount of materials sent to recycling, to landfilling and to waste-to-energy, by highlighting that the sorting of residual waste can further increase the secondary materials amount. The utilisation of energy recovery to treat the low-grade waste allows the maximisation of waste diversion from landfill with a low production of hazardous ash. A preliminary economic balance has been carried out to define the gate fee of the waste management system that was in the range of 84-145 € t(-1) without including the separate collection cost. The cost of door-by-door separate collection, designed to ensure the collection of five separate streams, resulted in 250 € t(-1) ±30%. PMID:26253498

  4. Counterstatement to Article Entitled "A Framework for Evaluation of Marine Spatial Data Geoportals Using Case Studies"

    Directory of Open Access Journals (Sweden)

    Seip Christian

    2015-12-01

    Full Text Available In December 2014 in volume 60 issue 4 a paper was published entitled “A Framework for Evaluation of Marine Spatial Data Geoportals Using Case Studies” by Marina Tavra, Vlado Cetl and Tea Duplancic Leder which is suspected to constitute academic misconduct. This comment reasons that the core of the paper was taken from another source and thus does not offer new and original scientific work and therefore does not add knowledge to the body of science. Furthermore it argues that apart from the plagiarism the paper shows major weaknesses and thus should have not been published even it was not plagiarized.

  12. Case studies of thermal energy storage (TES) systems: Evaluation and verification of system performance. Final report

    Akbari, H.; Sezgen, O.

    1992-01-01

    We have developed two case studies to review and analyze energy performance of thermal energy storage CMS systems in commercial buildings. Our case studies considered two partial ice storage systems in Northern California. For each case, we compiled historical data on TES design, installation, and operation. This information was further enhanced by data obtained through interviews with the building owners and operators. The performance and historical data of the TES systems and their components were grouped into issues related to design, installation, operation, and maintenance of the systems. Our analysis indicated that (1) almost all problems related to the operation of TES and non-TES systems could be traced back to the design of the system, and (2) the identified problems were not unique to the TES systems. There were as many original problems with ``conventional`` HVAC systems and components as with TES systems. Judging from the problems related to non-TES components identified in these two case studies, it is reasonable to conclude that conventional systems have as many problems as TES systems, but a failure, in a TES system may have a more dramatic impact on thermal comfort and electricity charges. The objective of the designers of the TES systems in the case-study buildings was to design just-the-right-size systems so that both the initial investment and operating costs would be minimized. Given such criteria, a system is typically designed only for normal and steady-state operating conditions-which often precludes due consideration to factors such as maintenance, growth in the needed capacity, ease of the operation, and modularity of the systems. Therefore, it is not surprising to find that these systems, at least initially, did not perform to the design intent and expectation and that they had to go through extended periods of trouble-shooting.

    Full Text Available Students can enhance their soft skills and learning experience through the use of group projects. However, evaluating group project performance has become very challenging. This paper presents the concept of group management in measuring individual performance in group projects in an academic setting. Individual performances in similar courses were also compared based on two consecutive semesters (Semesters 1 and 2. The respondents for this study were first year students who attended similar courses for both semesters. Performance measurement was based on peer review and lecturer evaluations. The criteria for these evaluations were similar for both semesters. The current study aims to determine the weaknesses and strengths of an individual in a group, and relate them with group performance based on the individual presentation marks. The study also analyzes the relationship between these two performance tools. Findings indicate that peer review and lecturer evaluations can be used to determine the performance of students in a group project, and that these two evaluation tools are not significantly correlated.

    Full Text Available This article presents the findings of a qualitative evaluation on the effect of a specialised software tool on the efficiency and quality of assignment marking. The software, Lightwork, combines with the Moodle learning management system and provides support through marking rubrics and marker allocations. To enable the evaluation a framework has been developed that is based on an extensive literature review and interviews with academics in tertiary settings. The framework introduces key factors that are crucial to educationally sound and efficient assignment marking. The use of Lightwork is compared to the prior experiences of participants who used either electronic- or paper-based approaches. The findings are analysed using the framework. The study indicates that Lightwork is well suited to support efficient, high quality assignment marking. It is suggested that the evaluation framework can be used for future studies in this area.

    Full Text Available Extended abstract 1- IntroductionPublic spaces, which belong to all the individuals of different ages, occupations, cultures, and races with no restriction, are one of the most important parts in a city. Today, the importance of the studies on these spaces, considering the needs of the citizens, is more evident. Study and evaluation of urban public spaces, is an urgent necessity in planning the urban management and improvement, and it is a sign of the reproduction of these spaces which is done to improve the city in cultural, social and structural aspects. The approach to the study of these spaces includes 3 perspectives that are considered problems in literature related to urban society: a Surfaces or areas devoted to public occupancy: the discussion here is the fact that how much of the general net area is devoted to public occupancy. b Distribution of these spaces over the city: In this part, the dispersion and accumulation of each one of the public occupancies in a specific area, is compared to its standard ratio. The purpose of researching and studying urban public spaces (in this case, Tabriz is as follows: a Evaluation of quantitative status of public spaces in Tabriz; b Analyzing the settlement of public spaces in Tabriz and the dispersion of these areas; c Comparing the different public spaces in distinct regions of Tabriz; d Presenting required strategies to improve the general status of public spaces in Tabriz. The following research discusses these two assumptions: a There is a meaningful relationship between the area and per capita public space in Tabriz and the current existing standards of the country; b There is a meaningful difference between different regions of the city in terms of development. The research method in this study is descriptive-analytical. Statistical research population is the city of Tabriz which, based on the general pattern of the city, is divided into 9 urban areas.

    Full Text Available Problem statement: The dam body and foundation seepage is one of the important points in design parameters. This index is related to the permeability. There fore permeability is one of the basic parameter in design grout curtain, prevent water escape from foundation and avoid negative seepage pressure in borrow materials, so grouting is used. Grouting means injected materials like cement or chemical materials under pressure to rock or soil layers. Approach: Purpose of grouting is treatment fractures, fissures, increase strength and decrease seepage. Grout curtain is used for sealing beneath dam body and other structure to obtain above aspects. Results: The present research dealing to study the geotechnical characteristics and conditions of two damsites (Kavar and Sheshpir dam regarding to their permeability and groutability. Permeability in rock mass is controlled by jointing and their characteristics. The Kavar dam may be constructed on Gareh Aghaj river. This site is located in 40 km southwest of Fars province, Iran. The river flow direction is parallel to the local syncline axis. The main geological features of damsite are faults, fractures and gypsum lenses that they may lead to water escape from reservoir. The rocks in the right abutment of the dam are heavily crushed with low strength. Therefore it is expected that water escape from this zone and some parts of dam axis may happen. This is approved from boreholes logs analysis and Water Pressure Tests (WPT. The other dam which called Sheshpir is located in west of Shiraz, Iran. Regarding to structural geology of this site, two large anticlines are extended in general direction of Zagros mountain range (northeast- southwest. The geology index features are karstic and jointed rock with faults. In general, regarding the grout-curtain design for each case, it is necessary to evaluate the volume of grout and injection system. Because of complexity of local structural geology especially rock

    Full Text Available The number of Free Online Machine Translation (FOMT users witnessed a spectacular growth since 1994. FOMT systems change the aspects of machine translation (MT and the mass translated materials using a wide range of natural languages and machine translation systems. Hundreds of millions of people use these FOMT systems to translate the holy Quran (Al-Qur?an verses from the Arabic language to other natural languages, and vice versa. In this study, an automatic evaluation for the use of FOMT systems to translate Arabic Quranic text into English is conducted. The two well-known FOMT systems (Google and Bing Translators are chosen to be evaluated in this study using a metric called Assessment of Text Essential Characteristics (ATEC. ATEC metric is one of the automatic evaluation metrics for machine translation systems. ATEC scores the correlation between the output of a machine translation system and professional human reference translation based on word choice, word orders and the similarity between MT output and the human reference translation. Extensive evaluation has been conducted on two well-known FOMT systems to translate Arabic Quranic text into English. This evaluation shows that Google translator performs better than Bing translator in translating Quranic text. It is noticed that the average ATEC score does not exceed 41% which indicates that FOMT systems are ineffective in translating Quranic texts accurately.

    2010-07-01

    Full Text Available The evaluation of the hidden economy involves major difficulties related to the use of an adequate methodology and to ensuring the necessary database for estimating some econometric models and some economic variables. The studies conducted showed that the size and forms of the informal economy differ from one country to another. The transition from the economies of the former socialist countries led to an increase in the size of the hidden economy. The highest levels are recorded in some former Soviet republics and in some South American countries. The evaluations made at the level of Romania estimated that the hidden economy accounts for approximately 30% of the Gross Domestic Product. This paper evaluates the size of the hidden economy on the basis of an econometric approach which assesses the cash outside the banking system according to various factors and to its use in official and hidden economy transactions.

From a methodological point of view we questioned students from different specializations belonging to the Faculty of Geography, “Babeş-Bolyai” University in Cluj-Napoca, Romania. The chosen sample was not established from the very beginning but the questionnaire was applied during courses and seminars, so the percentage of the respondents is directly proportional to students’ presence at the respective classes. Regarding the evaluating practice, the study reveals a series of specific traits such as: high percentage of the written exams in students evaluation, high dose of subjectivity presented by the responding students or the existence of a rather big discrepancy in the respondents percentage of each specialization. We noticed students’ preferences for the evaluator’s feedback at the end of the evaluation process but, also, the chance of sitting again for the exam.

    Full Text Available The purpose of this paper was to identify the existing criteria of various conventional databases that are considered in evaluating journals in the scholarship of library & information science (LIS journals and accordingly developed a tool box to evaluate some selected journals of LIS in South Asian Association of Regional Cooperation (SAARC countries. Journals have been evaluated by applying 30 criteria based on the current measures used by Thompson Reuter, SCOPUS, SciELO, LISA, LISTA, etc. The result indicates that although there are a considerable number of journals being published in India since long time, only a few journals are qualitatively strong. The review policy as mentioned in documentation, subject coverage can be considered as their strength, the geographic non-diversity of members in Editorial Board, contributors are their weakness. Most of journals are indexed in LISA and LISTA, however no journals are yet to include in JCR. Overall, to cope-up with international standard journals need to consider their publication policy thoroughly. The findings of the study seems to be useful for (a academics – to know the list of journals which adhere to the quality requirements of LIS discipline; (b librarians – to know the core LIS journals of SAARC countries in LIS discipline for their clients; (c policy makers – to measure the weightage of publication, while evaluating performance for career and promotion, to evaluate individual research performance, while releasing grants for academic projects.

  12. Evaluation of an artificial intelligence guided inverse planning system: Clinical case study

    International Nuclear Information System (INIS)

    Purpose: An artificial intelligence (AI) guided method for parameter adjustment of inverse planning was implemented on a commercial inverse treatment planning system. For evaluation purpose, four typical clinical cases were tested and the results from both plans achieved by automated and manual methods were compared. Methods and materials: The procedure of parameter adjustment mainly consists of three major loops. Each loop is in charge of modifying parameters of one category, which is carried out by a specially customized fuzzy inference system. A physician prescribed multiple constraints for a selected volume were adopted to account for the tradeoff between prescription dose to the PTV and dose-volume constraints for critical organs. The searching process for an optimal parameter combination began with the first constraint, and proceeds to the next until a plan with acceptable dose was achieved. The initial setup of the plan parameters was the same for each case and was adjusted independently by both manual and automated methods. After the parameters of one category were updated, the intensity maps of all fields were re-optimized and the plan dose was subsequently re-calculated. When final plan arrived, the dose statistics were calculated from both plans and compared. Results: For planned target volume (PTV), the dose for 95% volume is up to 10% higher in plans using the automated method than those using the manual method. For critical organs, an average decrease of the plan dose was achieved. However, the automated method cannot improve the plan dose for some critical organs due to limitations of the inference rules currently employed. For normal tissue, there was no significant difference between plan doses achieved by either automated or manual method. Conclusion: With the application of AI-guided method, the basic parameter adjustment task can be accomplished automatically and a comparable plan dose was achieved in comparison with that achieved by the manual

    2004-12-01

    Full Text Available There has been a wealth of investigation into the use of online multiple-choice questions as a means of summative assessment, however the research into the use of formative MCQs by the same mode of delivery still remains patchy. Similarly, research and implementation has been largely concentrated within the Sciences and Medicine rather than the more discursive subjects within the Humanities and Social Sciences. The INQUIRE (Interactive Questions Reinforcing Education Evaluation Project was jointly conducted by two groups at the University of Oxford–the Saïd Business School and the Academic Computing Development Team to evaluate the use of online MCQs as a mechanism to reinforce and extend student learning. This initial study used a small set of highly focused MCQ tests that were designed to complement an introductory series of first-year undergraduate management lectures. MCQ is a simple and well-established technology, and hence the emphasis was very much on situating the tests within the student experience. The paper will cover how the online MCQs are intended to fit into the Oxford Undergraduate study agenda, and how a simple evaluation was executed and planned to investigate their usage and impact. The chosen method of evaluation was to combine focus groups with automated online methods of tracking, and the paper discusses the findings of both of these.

    2013-08-01

    Full Text Available Precipitation in mountain regions is often highly variable and poorly observed, limiting abilities to manage water resource challenges. Here, we evaluate remote sensing and ground station-based gridded precipitation products over Nepal against weather station precipitation observations on a monthly timescale. We find that the Tropical Rainfall Measuring Mission (TRMM 3B-43 precipitation product exhibits little mean bias and reasonable skill in giving precipitation over Nepal. Compared to station observations, the TRMM precipitation product showed an overall Nash-Sutcliffe efficiency of 0.49, which is similar to the skill of the gridded station-based product Asian Precipitation-Highly Resolved Observational Data Integration Towards Evaluation of Water Resources (APHRODITE. The other satellite precipitation products considered (Global Satellite Mapping of Precipitation (GSMaP, the Climate Prediction Center Morphing technique (CMORPH, Precipitation Estimation from Remotely Sensed Information Using Artificial Neural Networks-Cloud Classification System (PERSIANN-CCS were less skillful, as judged by Nash-Sutcliffe efficiency, and, on average, substantially underestimated precipitation compared to station observations, despite their, in some cases, higher nominal spatial resolution compared to TRMM. None of the products fully captured the dependence of mean precipitation on elevation seen in the station observations. Overall, the TRMM product is promising for use in water resources applications.

    2010-01-01

    Sedimentation aspects have a major role during the design of new reservoir projects because life of the reservoir mainly depends upon sediment handling during reservoir operation. Therefore, proper sediment management strategies should be adopted to enhance the life span of reservoirs. Basha Reservoir is one of the mega water resources projects which are being planned to construct on the Indus river. Under this study, the efficiency of four sediment management strategies were evaluated by usi...

    2015-03-01

    Association mapping has become a widely applied genomic approach to dissect the genetic architecture of complex traits. A major issue for association mapping is the need to control for the confounding effects of population structure, which is commonly done by mixed models incorporating kinship information. In this case study, we employed experimental data from a large sugar beet population to evaluate multi-locus models for association mapping. As in linkage mapping, markers are selected as cofactors to control for population structure and genetic background variation. We compared different biometric models with regard to important quantitative trait locus (QTL) mapping parameters like the false-positive rate, the QTL detection power and the predictive power for the proportion of explained genotypic variance. Employing different approaches we show that the multi-locus model, that is, incorporating cofactors, outperforms the other models, including the mixed model used as a reference model. Thus, multi-locus models are an attractive alternative for association mapping to efficiently detect QTL for knowledge-based breeding. PMID:25351864

    This study evaluated the body image perception in children with type 1 diabetes in order to identify symptoms of disordered eating behaviours early. Children with type 1 diabetes and controls showed underestimation and dissatisfaction with body size. The patients, especially girls, were more accurate in their perception of body size than the control group. The study sheds light on some of the underlying factors that may contribute to the development of disordered eating behaviours in adolescence. The causes of the differences of perception of body size are discussed. PMID:24752557

    This volume reports the analysis of the results of 30 case studies of grantees funded by the Energy-Related Inventions Program (ERIP). ERIP is one of several federal programs supporting invention and innovation in the private sector. It is a relatively small program with an annual budget of $5 to 6 million that focuses its attention on the independent inventor or small business with an energy-related invention. Support to the inventory or small business comes primarily in the form of a grant. The overall goal of the program is to stimulate innovation by individuals and small businesses and to assist in the development of promising energy-related inventions for eventual commercialization. This volume is an aggregation and synthesis of the data gathered in the case studies. (Volume 2 contains the case studies.) The case studies explore in-depth the characteristics, perceptions, and experiences of inventors and agency personnel who have participated in the ERIP. Thus they are a rich source of information for use in evaluating the process by which the program's goals and objectives are implemented and for evaluating the program;s usefulness in producing the results intended by the legislative mandate.

    Full Text Available Agile models promote fast development. XP and Scrum are the most widely used agile models. This paper investigates the phases of XP and Scrum models in order to identify their potentials and drawbacks. XP model has certain drawbacks, such as not suitable for maintenance projects and poor performance for medium and large-scale development projects. Scrum model has certain limitations, such as lacked in engineering practices. Since, both XP and Scrum models contain good features and strengths but still there are improvement possibilities in these models. Majority of the software development companies are reluctant to switch from traditional methodologies to agile methodologies for development of industrial projects. A fine integration, of software management of the Scrum model and engineering practices of XP model, is very much required to accumulate the strengths and remove the limitations of both models. This is achieved by proposing an eXScrum model. The proposed model is validated by conducting a controlled case study. The results of case study show that the proposed integrated eXScrum model enriches the potentials of both XP and Scrum models and eliminates their drawbacks.

    Full Text Available The use of e-commerce in small medium-sized enterprises (SMEs has become an important topic in information systems research. At present, there is a large number of well-documented benefits derived from e-commerce for small-medium enterprises (SMEs both in theoretical and practical literature. Despite the enormous attention given to encourage SMEs to adopt e-commerce both by academics as well as governments, little research has been carried out in identifying strategies of e-commerce adoption for SMEs in developing countries, especially Indonesia. It is, therefore, the aim of this paper to understand the factors and combinations of factors that SMEs need to be considered before embracing e-commerce into their business by providing a closer look at actual experience of Indonesian SMEs. Case study research was carried out to analyse and explain the underlying factors that are likely to determine the varying extent of e-commerce adoption in SMEs, especially the service sector. The findings of the case studies have further extended into the development of proposed practical framework to illustrate how e-commerce adoption should be carried out from a strategic perspective.

  7. Evaluation methods for improving surface geometry of concrete floors: A case study

    Directory of Open Access Journals (Sweden)

    Full Text Available Among various construction activities, related to concrete pavement technologies, an important role is reserved to industrial floors. For these structures it is necessary to ensure resistance and stability, durability, reliability, and many other properties. In particular, the flatness and the levelness are special requirements that assume a real significance respect to functional performances, especially when the pavement has to allow the movement of vehicles and goods or the storage in elevated stacks or shelves. These geometric properties can be defined in different ways, but in every cases they are referred to pavement surface, that has to be even (without superelevated or depressed areas and level (horizontal, without grades, curvatures, and waves. The acceptance limits are defined by technical standards, in various countries, together with the suitable methods for measurements and controls. In many cases, however, these methods are considered not really feasible or easy, in particular when a continuous sampling of the pavement, along selected alignments, is needed. In particular, the paper describes the operating procedures to calculate indexes FF and FL, according to ASTM 1155M standard, starting from data provided by a contact profilometer. If the target values are not reach, it is necessary to provide some alternative solutions to avoid the demolition of the slabs or the payment of penalties by the builder, if this is required by the contract. There are two main possible methods for increasing flatness and levelness while other functional surface properties are maintained at the expected levels: the surface grinding and the overtopping with self-levelling and high resistance resins. A case study where the two alternative methods are applied to improve flatness and levelness of a surface is presented. The results of measures made before and after the treatments showed that both the solutions are able to ensure, within certain limits, the

    2016-04-01

    In this study, Turkey earthquake catalog of the events within the time period of 1900-2015 prepared by Boǧaziçi University Kandilli Observatory and Earthquake Research Institute is analyzed. The catalog consists of earthquakes occurred in Turkey and surrounding area (32o-45oN/23o-48oE). The current earthquake catalog data has been checked in two aspects; the time dependent variation and compliance for different regions. Specifically the data set prior to 1976 was found deficient. In total, 7 regions were evaluated according to the tectonic specifications and data set. In this study for every region original data were used without any change; b- values, a- values, Magnitude of completeness (Mc) were calculated. For the calculation of b- values focal depth was selected as h= 0-50 km. One of the important complications for the seismic catalogs is discriminating real (natural) seismic events from artificial (unnatural) seismic events. Therefore within the original current catalog events especially artificial quarry blasts and mine blasts have been separated by declustering and dequarry methods. Declustering process eliminates induced earthquakes especially occurred in thermal regions, large water basins, mine regions from the original catalogs. Current moment tensor catalog prepared by Kalafat, 2015 the faulting type map of the region was prepared. As a result, for each region it is examined if there is a relation between fault type and b- values. In this study, the hypothesis of the relation between previously evaluated and currently ongoing extensional, compression, strike-slip fault regimes in Turkey and b- values are tested one more time. This study was supported by the Department of Science Fellowship and Grant programs (2014-2219) of TUBITAK (The Scientific and Technological Research Councilof Turkey). It also encourages the conduct of the study and support the constructive contributionthat Prof.Dr. Nafi TOKSÖZ to offer my eternal gratitude.

    Full Text Available Abstract The purpose of this case study was to use an evidence based medicine approach to work through an unusual way of treating a common problem. We looked at an example of an in-patient with severe refractory psychotic depression who had been resistant to treatment with a combination of antidepressant, antipsychotics, mood stabiliser, and concomitant ECT therapy. We then undertook a literature search for the use of clozapine in a patient with severe refractory depression. Although the resulting evidence was low level and thin, we felt on balance that a trial of clozapine was justified. We used a BPRS inventory to monitor her mood prior to commencing clozapine. Her mood and functional abilities were monitored as her clozapine was titrated upwards. Our patient showed a significant improvement in mood and functional abilities and a reduction in her BPRS score during this period. Her symptoms improved to the point where she was successfully discharged home on a combination of clozapine and an antidepressant. The improvement was sustained for a further two years. We thought this was an important case to highlight the limited evidence in using this successful form of treatment for a common clinical problem and that further research in this area was needed.

  10. Use of genomic data in risk assessment case study: II. Evaluation of the dibutyl phthalate toxicogenomic data set

    International Nuclear Information System (INIS)

    An evaluation of the toxicogenomic data set for dibutyl phthalate (DBP) and male reproductive developmental effects was performed as part of a larger case study to test an approach for incorporating genomic data in risk assessment. The DBP toxicogenomic data set is composed of nine in vivo studies from the published literature that exposed rats to DBP during gestation and evaluated gene expression changes in testes or Wolffian ducts of male fetuses. The exercise focused on qualitative evaluation, based on a lack of available dose–response data, of the DBP toxicogenomic data set to postulate modes and mechanisms of action for the male reproductive developmental outcomes, which occur in the lower dose range. A weight-of-evidence evaluation was performed on the eight DBP toxicogenomic studies of the rat testis at the gene and pathway levels. The results showed relatively strong evidence of DBP-induced downregulation of genes in the steroidogenesis pathway and lipid/sterol/cholesterol transport pathway as well as effects on immediate early gene/growth/differentiation, transcription, peroxisome proliferator-activated receptor signaling and apoptosis pathways in the testis. Since two established modes of action (MOAs), reduced fetal testicular testosterone production and Insl3 gene expression, explain some but not all of the testis effects observed in rats after in utero DBP exposure, other MOAs are likely to be operative. A reanalysis of one DBP microarray study identified additional pathways within cell signaling, metabolism, hormone, disease, and cell adhesion biological processes. These putative new pathways may be associated with DBP effects on the testes that are currently unexplained. This case study on DBP identified data gaps and research needs for the use of toxicogenomic data in risk assessment. Furthermore, this study demonstrated an approach for evaluating toxicogenomic data in human health risk assessment that could be applied to future chemicals

    Full Text Available Abstract Background Priority setting is one of the most difficult issues facing hospitals because of funding restrictions and changing patient need. A deadly communicable disease outbreak, such as the Severe Acute Respiratory Syndrome (SARS in Toronto in 2003, amplifies the difficulties of hospital priority setting. The purpose of this study is to describe and evaluate priority setting in a hospital in response to SARS using the ethical framework 'accountability for reasonableness'. Methods This study was conducted at a large tertiary hospital in Toronto, Canada. There were two data sources: 1 over 200 key documents (e.g. emails, bulletins, and 2 35 interviews with key informants. Analysis used a modified thematic technique in three phases: open coding, axial coding, and evaluation. Results Participants described the types of priority setting decisions, the decision making process and the reasoning used. Although the hospital leadership made an effort to meet the conditions of 'accountability for reasonableness', they acknowledged that the decision making was not ideal. We described good practices and opportunities for improvement. Conclusions 'Accountability for reasonableness' is a framework that can be used to guide fair priority setting in health care organizations, such as hospitals. In the midst of a crisis such as SARS where guidance is incomplete, consequences uncertain, and information constantly changing, where hour-by-hour decisions involve life and death, fairness is more important rather than less.

    Full Text Available Effective utilization of scarce water resources has presented a significant challenge to respond to the needs created by rapid economic growth in China. In this study, the efficiency of the joint operation of the Three Gorges and Gezhouba cascade hydropower plants in terms of power generation was evaluated on the basis of a precise simulation-optimization technique. The joint operation conditions of the Three Gorges and Gezhouba hydropower plants between 2004 and 2010 were utilized in this research in order to investigate the major factors that could affect power output of the cascade complex. The results showed that the current power output of the Three Gorges and Gezhouba cascade complex had already reached around 90% of the maximum theoretical value. Compared to other influencing factors evaluated in this study, the accuracy of hydrological forecasts and flood control levels can have significant impact on the power generating efficiency, whereas the navigation has a minor influence. This research provides a solid quantitative-based methodology to assess the operation efficiency of cascade hydropower plants, and more importantly, proposes potential methods that could improve the operation efficiency of cascade hydropower plants.

    Rice is the most important cereal crop in the developing world and, in Europe, Italy is leader in rice production. The intensive cultivation of rice leads to continuous inputs chemicals as fertilizers, weeding and pesticides. The intensification of sustainable rice production by minimizing the impact on the environment of cultivation is a main issue . In this context this study, supported by the Italian National Project POLORISO (MIPAAF), aims to afford preliminary indications about the evaluation of ecological impact by different managements on soil mesofauna biodiversity. Biomonitoring of soil mesofauna, in particular nematodes and microarthropods, allows to determine the effects of crop management on the communities; the lack and/or reduction of these organisms can allow inference on the soil quality. This preliminary study aims at evaluate the different influence of conventional, integrated and biological managements on mesofauna communities. The samplings were conducted in Summer and Autumn 2013 near Vercelli (North Italy) in three study sites with similar pedologic characteristics but different in control strategies (conventional, organic farming, Integrated Pest Management (IPM)). The extraction of nematodes and microarthropods was performed by Bermann method and the Berlese-Tullgren selector, respectively. All specimens were counted and determined up to the order level. The biological soil quality was evaluated by Maturity Index (MI) for nematodes, BSQar and the soil Biological Classes (sBC)(range I-VII) for microarthropods. Regarding nematodes, Rhabditidae, Dorylamidae, Mononchidae, Tylenchidae and Heteroderidae were the most represented families. The Principal Component Analysis (PCA) evidenced that the trophic group of plant parasites was favored in organic farming, while groups of omnivores and predators were abundant in the other managements. The lowest nematodes' abundance was found in submerged rice soil with dominance of omnivores and plant

    Manufacturing equipment takes the task of operation and directly effects on the manufacturing process. One single Key Performance Indicator (KPI) is mainly employed to evaluate equipment in most studies, neither inte-grating the KPIs into a completed evaluation system nor considering the impact and conflict among KPIs. In this paper, a KPI evaluation architecture is presented to define and analyze KPIs, and then a common structure for KPI to obtain the KPI set of manufacturing equipment is introduced. An available multi-KPI coordination model is proposed to discern and balance the relationship among multi-KPI. Final y, a case study is introduced to il ustrate the applicability of the coordination model by using multi-objective optimization strategy and an efficient solu-tion is obtained.

    The so far implemented enterprise resource planning (ERP) systems have in many cases failed to meet the requirements regarding the business process control, decrease of business costs and increase of company profit margin. Therefore, there is a real need for an evaluation of the influence of ERP on the company's performance indicators. Proposed in this article is an advanced model for the evaluation of the success of ERP implementation on organisational and operational performance indicators in oil-gas companies. The recommended method establishes a correlation between a process-based method, a scorecard model and ERP critical success factors. The method was verified and tested on two case studies in oil-gas companies using the following procedure: the model was developed, tested and implemented in a pilot gas-oil company, while the results were implemented and verified in another gas-oil company.

  19. Evaluation of region-specific residential energy systems for GHG reductions: Case studies in Canadian cities

    International Nuclear Information System (INIS)

    This study estimates energy use and greenhouse gas (GHG) emissions associated with operations of alternative residential energy systems. In case studies, the same detached four-bedroom house built in accordance with R2000 standards is studied in five Canadian cities with different climate and electricity mix. Conventional energy systems and alternatives using three technologies, namely ground source heat pumps (GSHPs), photovoltaics, and energy-efficient appliances; and their combinations are investigated. The results show that using a GSHP in Calgary may increase overall GHG emissions, as electricity to drive the pump is primarily produced in coal-fired power stations. Using photovoltaics to generate electricity from carbon-free sources or energy-efficient appliances to reduce electricity demands result in almost no GHG reductions in Montreal and Vancouver, where over 90% of electricity comes from hydro power. The results also show that the use of photovoltaics in combination with GSHPs in Ottawa and Toronto, or with energy-efficient appliances in Calgary, can lead to more GHG reductions, compared to the use of a single technology. As a result, while climate affects energy use to some degree, local sources of electricity may have a greater impact on overall GHG emissions, which is an important measure of environmental impacts

    To prospectively evaluate the use of MRI with dynamic sequences during isolated limb perfusion (ILP) for soft tissue sarcomas, an aggressive local treatment using very high-dose chemotherapy and tumor necrosis factor aimed at avoiding limb amputation. Twenty-six patients were referred for ILP over one and a half years; eight were excluded as the lesions were either too proximal or suspicious inflammatory changes without tumor were found on the initial MRI, or the vascular status was poor. The indications for ILP were: vessel nerve involvement (13), multiple lesions (8), tumor size (4) or the presence of pulmonary metastases (2). MRI was performed 1 and 2 months after ILP, immediately prior to surgery and histological analysis. The MR examinations included T1-weighted SE and fast SE T2-weighted fat-saturated sequences, as well as dynamic sequences (T1-weighted SE repeated six times every 40 s), displaying the maximum intensity slope in each pixel. The tumor had disappeared in three patients. One patient still had histologically proven isolated widespread tumor cells without a mass. The tumor size had increased in two patients. In six patients, the size of the tumor had not changed but it had become completely necrotic, with a thin wall.In three patients, after an initially good result MRI demonstrated that the tumor wall had become thickened from 1 to 2 months after ILP. Dynamic MRI was mainly useful during the initial examination, demonstrating two patients with inflammatory changes without tumor. Three amputations and a second ILP were proposed based on poor results. Conservative limb-sparing surgery was successful in the other cases. MRI proved valuable in demonstrating the variable responses to ILP. (orig.)

  2. MR imaging in the evaluation of isolated limb perfusion: a prospective study of 18 cases

    To prospectively evaluate the use of MRI with dynamic sequences during isolated limb perfusion (ILP) for soft tissue sarcomas, an aggressive local treatment using very high-dose chemotherapy and tumor necrosis factor aimed at avoiding limb amputation. Twenty-six patients were referred for ILP over one and a half years; eight were excluded as the lesions were either too proximal or suspicious inflammatory changes without tumor were found on the initial MRI, or the vascular status was poor. The indications for ILP were: vessel nerve involvement (13), multiple lesions (8), tumor size (4) or the presence of pulmonary metastases (2). MRI was performed 1 and 2 months after ILP, immediately prior to surgery and histological analysis. The MR examinations included T1-weighted SE and fast SE T2-weighted fat-saturated sequences, as well as dynamic sequences (T1-weighted SE repeated six times every 40 s), displaying the maximum intensity slope in each pixel.

    Full Text Available Invasive infections caused by Candida spp. are an important problem in immunocompromised patients. There is scarce data on the epidemiology of blood stream candidiasis in Salvador, Brazil. This study evaluates the risk factors associated with candidemia, among patients admitted to three tertiary, private hospitals, in Salvador, Brazil. We conducted a case-control, retrospective study to compare patients with diagnosis of candidemia in three different tertiary hospitals in Salvador, Brazil. Patients were matched for nosocomial, acquired infections, according to the causal agent: cases were defined by positive blood cultures for Candida species. Controls were those patients who had a diagnosis of systemic bacterial infection, with a positive blood culture to any bacteria, within the same time period (± 30 days of case identification. The groups were compared for the main known risk factors for candidemia and for mortality rates. A hundred thirty-eight patients were identified. Among the 69 cases, only 14 were diagnosed as infected by Candida albicans. Candida species were defined in only eight cultures: C. tropicalis (4 cases, C. glabrata, C. parapsilosis, C. guillermondi, C. formata (1 case each. The main risk factors, identified in a univariate analysis, were: presence of a central venous catheter (CVC, use of parenteral nutrition support (PNS, previous exposure to antibiotics, and chronic renal failure (CRF. No association was detected with surgical procedures, diabetes mellitus, neutropenia or malignancies. Patients were more likely to die during the hospitalization period, but the rates of death caused by the infections were similar for cases and controls. The length of hospitalization was similar for both groups, as well as the time for a positive blood culture. Blood stream infection by Candida spp. is associated with CVC, PNS, previous use of antibiotics, and CRF. The higher mortality rate for cases probably better reflects the severity

  5. Comparative evaluation of activity-based costing and variable costing: a case study at IPEN

    International Nuclear Information System (INIS)

    This research aims to compare the results with the application of Activity Based Costing and Variable Costing methods in an administrative unit of the Brazilian Federal Government: the Radiopharmacy Facility of IPEN (Institute for Energy and Nuclear Research), which produces radiopharmaceuticals products and develops R and D activities. Faced with the need to adopt a more economical and managerial public administration, this research has provided information to assess which of the two costing methods proves more suitable for cost management in that unit. The research is exploratory and a single-case study. We traced about 80% of material costs by observation 'in loco' of the entire manufacturing process of technetium generator, which represents the main product in terms of production volume and revenues. The results show that the Contribution Margin Variable Costing of 29.12% is very close to the operating income of 28.86%, ahead of support activities, obtained by ABC. It is also noted that the operational result of the product does not change by using either one or another costing method. In the two costing methods the end result is 24.20%. This occurs because the production is on demand. There is no inventory of finished product because it is radioactive. The research has revealed that both methods provide useful information for the management and optimization of costs and results of processes/activities, and that the two methods, in this case, may be used in an integrated and complementary approach, enabling to use the best information content of both.

    The wolf ( Canis lupus) is used as a case study to rate Natura 2000 sites in Greece based on preferred wolf habitat characteristics and test whether the network is suitable for their conservation. Road density, agricultural area, site area, connectivity, food availability (i.e., presence of natural prey), and elevation in 237 sites are combined in a logistic regression model. The occurrence of the wolf's natural prey was the most prevalent factor determining wolf presence, followed by agricultural cover. Considering the current status of these features at N2K site level, most sites currently hosting wolves (85.7 %) have good or excellent prospects for the long-term presence of the wolf. On the contrary, 11 sites which now have wolves are predicted to be ineffective in keeping them in the future due to the absence of wild ungulates and their high agricultural coverage. Four sites with no wolf presence currently have excellent prospects to host wolves in the future. Roadless sites are a priority for protection and retaining their current condition is strongly suggested. The proposed approach aims to detect gaps in protection for the wolf and identify priority sites in need of mitigation actions. It can also assist the assessment of conservation policies in Greece and elsewhere toward accomplishing set goals in protected areas. By focusing on wolf protection, we hope to increase agencies' attention to deal with conservation effectiveness, especially in cases like Greece, where a number of sites are insufficiently known and protected and management measures are not properly implemented.

    Debris flow is a natural disaster common in mountainous areas in Japan and China. It has great destructive force because of its high density and speed, and often causes great losses to human life and the economy. Therefore, countermeasures such as sabo facilities are very essential to reduce the damages. In this study, we applied GUI equipped debris flow simulator KANAKO to evaluate the effects of the debris flow countermeasures in Hongqiao Gully, Sichuan Province, China. The results show that the full dams which were constructed in 2001 still have the function for controlling debris flow to a certain degree. Because the trapped debris flow materials decrease the gully bed slope, and debris flow velocity decreases consequently. Through the comprehensive control of debris flow including trapping, drainage and deposition works, the simulation results indicate that the effects of the countermeasures in 2001 and 2006 are very good. The countermeasures can ensure residents’ life and property on the alluvial fan.

    The value of supervision that is provided to student nurses during their education is high. The aim of this study was to evaluate the organizational changes in an educational program for Swedish student nurses, focusing on the content and quality of process-oriented supervision. The research question was: Do the organizational changes pertaining to the student nurses' supervision (its reduced frequency and mandatory nature) influence its content and quality and, if so, in which ways? The data were collected by focus group discussions and were analyzed by a qualitative content analysis. Three themes emerged: difficulties with the new organization, the content and learning outcomes of supervision, and the nurse supervisors' intentions. Supervision is recommended in order to achieve the goal of nursing education and to ensure that student nurses gain an understanding of their experiences, thus equipping them with the professional skills and competence that are required to meet patients' needs.

    With changing paradigms of disaster preparedness, the safety and security of critical infrastructure in the event of a geo-hazard has become increasingly important. In a developing and densely populated country like India, which is vulnerable to many different geo-hazards, a lack of clear policy directive regarding safety of such infrastructure could be especially damaging both in terms of life and property. The problem is most acute in India's mega cities, where inefficient infrastructure means that facilities like transportation, communication, and electricity generation are obsolete and vulnerable to sudden disruptions. The present study takes the case of the National Capital Territory of Delhi and attempts to examine the critical infrastructures of the city in the event of an earthquake. Delhi lies in a very active seismic zone with various faults in and around the city. The Government of India has classified Delhi in Zone 4 (High Risk Zone) based on past and expected seismic activities in the Indo-Gangetic Plains. With a population of over 20 Million in the Urban Agglomeration of Delhi, any major earthquake in an already overstretched infrastructure could have a devastating impact. This study will test the critical infrastructures of the city in terms of their disaster preparedness and suggest ways and measures to increase the same.

    Disassembly and recycling of E-waste creates a series of environmental problems. The selection of a technologically reliable, environmentally friendly, economically affordable and socially acceptable recycling technology for E-waste is a significant question. This study establishes a Monte-Carlo mathematical model of cost minimization, given the constraints of environmentally sound handling of the e-waste, in the context of Crystal Ball risk assessment and evaluation software. By following the streams of the different treatment processes, which consist of various technologies including disassembly, recycling and disposal, the econom-ics of various possibilities were identified and the optimal recycling technology proposed. The key factors of the proposed scenarios were determined by using sensitivity analysis. The results of this study show that, for discarded refrigerators, the operating life span plays the key role. The model supports maintenance and resale of the short lived refrigerators. For the longer lived refrigerators material recycling is recommended by the model. Sensitivity analysis shows that purchase cost, plastic sale price, condenser sale price and disassembly costs are the main effects. This study provides a significant technical support for policy making in E-waste management.

    This article describes the development and ongoing evaluation of a method of service user facilitated case study in health and social care education in a U.K. University. An action research approach (Norton 2009) has been used in which the aim of the work is to improve personal practice with the aim of enhancing the student experience. The paper is written from the perspective of the service user with support from an academic colleague. The paper describes how a narrative monologue, over time is developed into an interactive case study. In draws upon literature from service user involvement, case study and pedagogic action research. The research group are health and social care students both under and post-graduates. Analysis is via a session evaluation form. Thematic analysis draws out key themes. Firstly that first person accounts have a reasonance and interest with students. Secondly that the built in thinking time helps students to develop their reflection and critical thinking skills. Furthermore a theme emerges on how the technique supports students with their future careers. Finally the author reflects on how the approach enables the development of teaching practice and enhanced student learning. PMID:22036271

    Full Text Available Evaluation of educational interventions is often focused on immediate and/or short-term metrics associated with knowledge and/or skills acquisition. We developed an educational intervention to support international medical graduates working in rural Victoria. We wanted an evaluation strategy that included participants??reactions and considered transfer of learning to the workplace and retention of learning. However, with participants in distributed locations and limited program resources, this was likely to prove challenging. Elsewhere, we have reported the outcomes of this evaluation. In this educational development report, we describe our evaluation strategy as a case study, its underpinning theoretical framework, the strategy, and its benefits and challenges. The strategy sought to address issues of program structure, process, and outcomes. We used a modified version of Kirkpatrick?占퐏 model as a framework to map our evaluation of participants??experiences, acquisition of knowledge and skills, and their application in the workplace. The predominant benefit was that most of the evaluation instruments allowed for personalization of the program. The baseline instruments provided a broad view of participants??expectations, needs, and current perspective on their role. Immediate evaluation instruments allowed ongoing tailoring of the program to meet learning needs. Intermediate evaluations facilitated insight on the transfer of learning. The principal challenge related to the resource intensive nature of the evaluation strategy. A dedicated program administrator was required to manage data collection. Although resource-intensive, we recommend baseline, immediate, and intermediate data collection points, with multi-source feedback being especially illuminating. We believe our experiences may be valuable to faculty involved in program evaluations.

  20. Application case study of AP1000 automatic depressurization system (ADS) for reliability evaluation by GO-FLOW methodology

    International Nuclear Information System (INIS)

    Highlights: • Discussion on reasons why AP1000 equipped with ADS system comparatively to PWR. • Clarification of full and partial depressurization of reactor coolant system by ADS system. • Application case study of four stages ADS system for reliability evaluation in LBLOCA. • GO-FLOW tool is capable to evaluate dynamic reliability of passive safety systems. • Calculated ADS reliability result significantly increased dynamic reliability of PXS. - Abstract: AP1000 nuclear power plant (NPP) utilized passive means for the safety systems to ensure its safety in events of transient or severe accidents. One of the unique safety systems of AP1000 to be compared with conventional PWR is the “four stages Automatic Depressurization System (ADS)”, and ADS system originally works as an active safety system. In the present study, authors first discussed the reasons of why four stages ADS system is added in AP1000 plant to be compared with conventional PWR in the aspect of reliability. And then explained the full and partial depressurization of RCS system by four stages ADS in events of transient and loss of coolant accidents (LOCAs). Lastly, the application case study of four stages ADS system of AP1000 has been conducted in the aspect of reliability evaluation of ADS system under postulated conditions of full RCS depressurization during large break loss of a coolant accident (LBLOCA) in one of the RCS cold legs. In this case study, the reliability evaluation is made by GO-FLOW methodology to determinate the influence of ADS system in dynamic reliability of passive core cooling system (PXS) of AP1000, i.e. what will happen if ADS system fails or successfully actuate. The GO-FLOW is success-oriented reliability analysis tool and is capable to evaluating the systems reliability/unavailability alternatively to Fault Tree Analysis (FTA) and Event Tree Analysis (ETA) tools. Under these specific conditions of LBLOCA, the GO-FLOW calculated reliability results indicated

    On September 29, 2009, an Mw = 8.1 earthquake at 17:48 UTC in Tonga Trench generated a tsunami that caused heavy damage across Samoa, American Samoa, and Tonga islands. Tutuila island, which is located 250 km from the earthquake epicenter, experienced tsunami flooding and strong currents on the north and east coasts, causing 34 fatalities (out of 192 total deaths from this tsunami) and widespread structural and ecological damage. The surrounding coral reefs also suffered heavy damage. The damage was formally evaluated based on detailed surveys before and immediately after the tsunami. This setting thus provides a unique opportunity to evaluate the relationship between tsunami dynamics and coral damage. In this study, estimates of the maximum wave amplitudes and coastal inundation of the tsunami are obtained with the MOST model (T itov and S ynolakis, J. Waterway Port Coast Ocean Eng: pp 171, 1998; T itov and G onzalez, NOAA Tech. Memo. ERL PMEL 112:11, 1997), which is now the operational tsunami forecast tool used by the National Oceanic and Atmospheric Administration (NOAA). The earthquake source function was constrained using the real-time deep-ocean tsunami data from three DART® (Deep-ocean Assessment and Reporting for Tsunamis) systems in the far field, and by tide-gauge observations in the near field. We compare the simulated run-up with observations to evaluate the simulation performance. We present an overall synthesis of the tide-gauge data, survey results of the run-up, inundation measurements, and the datasets of coral damage around the island. These data are used to assess the overall accuracy of the model run-up prediction for Tutuila, and to evaluate the model accuracy over the coral reef environment during the tsunami event. Our primary findings are that: (1) MOST-simulated run-up correlates well with observed run-up for this event ( r = 0.8), it tends to underestimated amplitudes over coral reef environment around Tutuila (for 15 of 31 villages, run

    Full Text Available Tourism is an important sector in developing countries to support economic growth, and coastal areas are famous destinations in tourism. The plan and design for Balekambang coastal area as a tourism destination in East Java, Indonesia has been formulated and published. However, it seems lack ecological and social perspectives. This study examines coral reefs structure as one of the ecological parameter and tourist perspectives as social parameter for destination development evaluation. Twenty belt-transects were established along Balekambang coastline, and then divided into three sections, the east, the centre and the west sections. Every belt-transect was 200m in length and consists of 15 plots 1 x 2m. The tourist perspectives to Balekambang were determined using questionnaire among 234 respondents. Based on the Morisita similarity index, the coral reef of east section consists of 2 zones, the centre consists of 5 zones and west section consists of 4 zones. The Shannon diversity index (H’ among zones at every location was ranged. The diversity index of the east section ranged from 2.07 to 2.72, the central section ranged from 1.32 to 4.20, and the west section ranged from 3.13 to 4.20. Zones that were close to the coastline had lowest diversity indices than zones that located far from the coastline. Mostly, tourists stated that Balekambang was interesting, but the object of tourism should be added. Respondent knew there were forest surrounding Balekambang, and it has the possibility to develop as tourism destination. These findings argue that the forest conversion to cottage area that planned by the local government in the west section should be reviewed. It seems forest in the west section should be developed as a forest park to meet tourist needs and redistribute tourist concentration in the coastline. Keywords: Ecological and social evaluation, coastal, tourism, sustainable development, East Java.

    Objective: to evaluate epidemiological and radiological characteristics of the femoral shaft fractures, surgically treated from 1990 to 2005 at Hospital de Acidentados – Clínica Santa Isabel – in Goiânia, Goiás, aiming to contribute to better preventive and therapeutic measures planning to adopt on those fractures. Methods: 200 patients' files and x-rays with femoral shaft fractures have been retrospectively evaluated. Patients below the age of 10 years were not included because the treatment for this group was conservative. 25 files have been discarded for not supplying all the necessary data to the study. The patients were assessed for sex, age, side of the fracture, bone exposure, mechanisms of trauma, classification of the fractures, associated trauma, time for bone healing and types of surgical devices. Statistic analyses were made by chi-squared, Fisher and Student's-t tests, adopting as a significance level pTrampling accidents were prevalent among youngsters between 10 and 19 years old. Car accidents showed all the types of fractures, mostly associated to other traumas, reaching its peak incidence in the age group of 20-30 years. The treatment with Küntscher Nail resulted in a longer mean consolidation time, as well as fractures with unstable traces (B3,C1,C2,C3). Conclusion: we found a bi-modal characteristic the femoral shaft fractures, consistently to literature data, where the high energy mechanisms (traffic accidents, high falls and wounds from firearms), have been more frequent in young adults, men, generating unstable traces of fractures, with more serious associated trauma, while the other group with low energy trauma (simple falls), was more frequently seen in elderly female individuals with less unstable fracture traces, without associated trauma.

    2011-01-01

    Background Examining professional assessments of a blood product recall/withdrawal and its implications for risk and public health, the paper introduces ideas about perceptions of minimal risk and its management. It also describes the context of publicly funded blood transfusion in Canada and the withdrawal event that is the basis of this study. Methods Interviews with 45 experts from administration, medicine, blood supply, laboratory services and risk assessment took place using a multi-level sampling framework in the aftermath of the recall. These experts either directly dealt with the withdrawal or were involved in the management of the blood supply at the national level. Data from these interviews were coded in NVivo for analysis and interpretation. Analytically, data were interpreted to derive typifications to relate interview responses to risk management heuristics. Results While all those interviewed agreed on the importance of patient safety, differences in the ways in which the risk was contextualized and explicated were discerned. Risk was seen in terms of patient safety, liability or precaution. These different risk logics are illustrated by selected quotations. Conclusions Expert assessments did not fully converge and it is possible that these different risk logics and discourses may affect the risk management process more generally, although not necessarily in a negative way. Patient safety is not to be compromised but management of blood risk in publicly funded systems may vary. We suggest ways of managing blood risk using formal and safety case approaches.

    2003-08-01

    Generation of leachate from municipal solid waste (MSW) landfill in arid regions has long been neglected on the assumption that minimal leachate could be formed in the absence of precipitation. Therefore, a case study was conducted at two unlined MSW landfills, of different ages, in the state of Kuwait in order to determine the chemical characteristics of leachate and examine the mechanism of leachate formation. Leachate quality data were collected from both active and old (closed) landfills where co-disposal of MSW and other solid and liquid wastes is practiced. The analysis of data confirms that leachates from both landfills are severely contaminated with organics, salts and heavy metals. However, the organic strength of the leachate collected from the old landfill was reduced due to waste decomposition and continuous gas flaring. A significant degree of variability was encountered and factors which may influence leachate quality were identified and discussed. A water balance at the landfill site was assessed and a conceptual model was presented which accounts for leachate generation due to rising water table, capillary water and moisture content of the waste.

Methods Interviews with 45 experts from administration, medicine, blood supply, laboratory services and risk assessment took place using a multi-level sampling framework in the aftermath of the recall. These experts either directly dealt with the withdrawal or were involved in the management of the blood supply at the national level. Data from these interviews were coded in NVivo for analysis and interpretation. Analytically, data were interpreted to derive typifications to relate interview responses to risk management heuristics. Results While all those interviewed agreed on the importance of patient safety, differences in the ways in which the risk was contextualized and explicated were discerned. Risk was seen in terms of patient safety, liability or precaution. These different risk logics are illustrated by selected quotations. Conclusions Expert assessments did not fully converge and it is possible that these different risk logics and discourses may affect the risk management process more generally, although not necessarily in a negative way. Patient safety is not to be compromised but management of blood risk in publicly funded systems may vary. We suggest ways of managing blood risk using formal and safety case approaches.

  7. Environmental evaluation of societal industrial ecology - Case studies of its implementation in the Swedish transport and building sectors

    Roth, L.

    2001-08-01

    This thesis is a study of how to environmentally evaluate the Swedish concept 'kretsloppsanpassning', here termed Societal Industrial Ecology (SIE). The thesis is based on three case studies of its implementation in the transport and building sectors. The aim of the thesis is to study to what extent the implementation of SIE in the transport and building sectors leads to changes in material and energy flows and their management. The environmental management (solely in the transport sector) was studied in order to check implemented measures against the governmental goal definitions and validate the measures' inclusion and scope in the SIE concept. In order to environmentally analyse and discuss the changes in environmental management regarding material and energy flows, the industrial metabolism perspective was used. Then, measures were analysed as to how environmental evaluation could be applied and what the possible result would be. Finally, the implications of environmental evaluation for environmental management were discussed. The implementation of SIE in the transport and building sectors has generally lead to that the main part of measures are implemented on material outflows. However, the monitoring of material flows was mainly found on the inflow side. This means that the measures taken were not audited and the quantified information concerning material inflows seem not to influence planning of measures. implemented and planned SIE measures sometimes take place in a wider context than the internal organisation and thereby affect other actors in society. Compared with traditional environmental measuring, this makes other demands on how to environmentally evaluated these measures. Especially, wider system boundaries are a prerequisite to address and evaluate SIE measures. Environmental. evaluation in a systems approach would not result in a precise answer, even if the system studied were less complex than an industrial system. There are a lot

    Full Text Available Nowadays, because of the steel desired tensile, compressive strength, and light weight especially in the large spans, it has been widely popular in the bridge construction. On the other hand, there are some disadvantages including corrosion, buckling and weaknesses in the higher temperatures, and unsuitable weld which would be resolved using Fibres Reinforced Polymer (FRP profiles. The FRP is a remarkable class of composite polymers that can improve structural elements behaviours like as resistance against corrosion, fire, electricity, and magnetic fields. In this paper, composite GFRP & UHF beams along with the behaviour of I-shaped beam were studied and discussed under the point loads using numerical models, results were compared and verified with the experimental tests whereas two different beams were modelled and verified under static progressive loading performed with ABAQUS as an FEM base software. Finally, Moddares-Haqqani that is a steel girder bridge has been modeled by SAP software and maximum displacement has been determined. Then 4 GFRP beams modeled by ABAQUS software and best section has been determined. Beams are under dead and live loading. Purposes of this paper are evaluating of use of GFRP materials as a basic material in construction process and compare this operation with steel. Results shown that because of lower modulus of elasticity in GFRP compare with steel, displacement has increase in GFRP beams and hence beams dimension must be increase to limit displacement.

    Full Text Available The work reported in this paper presents the assessment of environmental performances of selected branded apparel T-Shirt products made by Bangladesh. The study is based on a standard evaluation tool named Higg Index which is basically used widely to measure the environmental sustainability of various apparel products. Higg Index is an internal self-assessment tool created by the outdoor apparel industry and Nike’s apparel environmental design tool which aims to aggregate information on the environmental performance of products. The Index considers performance across the full life-cycle of a product, including impacts from “input materials, manufacturing, packaging, transportation, use, and end-of-life.” Selected apparel branded T-Shirt products from S. Oliver, BUTex-Innovation, PUMA, Esprit, Aarong, and Yellow were taken into consideration. The results indicate that newly developed ecofriendly T-shirt and foreign branded products named S. Oliver, PUMA, and Esprit gained higher score but local branded product like Aarong and Yellow gained lower score in terms of environmental sustainability based on Higg Index assessment tool. Moreover, many weaknesses and opportunities for improvement of both local and foreign branded T-Shirt products have been identified and suggested which would eventually lead the fashion designer, apparel manufacturer, stakeholder, and consumer towards greener apparel products.

  15. Comprehensive benefit of flood resources utilization through dynamic successive fuzzy evaluation model: A case study

    Institute of Scientific and Technical Information of China (English)

    2010-01-01

    Taking the flood resources utilization in Baicheng, Jilin during 2002–2007 as the research background, and based on the entropy weight and multi-level & multi-objective fuzzy optimization theory, this research established a multi-level & semi-constructive index system and dynamic successive evaluation model for comprehensive benefit evaluation of regional flood resources utilization. With the year 2002 as the base year, the analyzing results showed that there existed a close positive correlation between flood utilization volume and its benefits, comprehensive evaluation value and its comparison increment. Within the six successive evaluation years, the comprehensive benefit of 2003 was the best, in which the benefit evaluation increment reached 82.8% whereas the year of 2004 was the worst, in which the increment was only 18.2%. Thus the sustainability and correctness of the evaluation were verified by six years successive evaluation and increment comparison. The analyzing results showed that the economic benefits, ecological benefits and social benefits of flood utilization were remarkable, and that the comprehensive benefit could be improved by increasing flood utilization capacity, which would promote the regional sustainable development as well. The established dynamic successive evaluation provides a stable theoretical basis and technical support for further flood utilization.

    The appearance of assimilable organic carbon (AOC), microbial regrowth, disinfection by-products (DBPs), and pipe corrosion in drinking water distribution systems are among those major safe drinking water issues in many countries. The water distribution system of Cheng-Ching Lake Water Treatment Plant (CCLWTP) was selected in this study to evaluate the: (1) fate and transport of AOC, DBPs [e.g., trihalomethanes (THMs), haloacetic acids (HAAs)], and other organic carbon indicators in the selected distribution system, (2) correlations between AOC (or DBPs) and major water quality parameters [e.g. dissolved oxygen (DO), free residual chlorine, and bacteria, and (3) causes and significance of corrosion problems of the water pipes in this system. In this study, seasonal water samples were collected from 13 representative locations in the distribution system for analyses of AOC, DBPs, and other water quality indicators. Results indicate that residual free chlorine concentrations in the distribution system met the drinking water standards (0.2 to 1 mg l(-1)) established by Taiwan Environmental Protection Administration (TEPA). Results show that AOC measurements correlated positively with total organic carbon (TOC) and UV-254 (an organic indicator) values in this system. Moreover, AOC concentrations at some locations were higher than the 50 microg acetate-C l(-1) standard established by Taiwan Water Company. This indicates that the microbial regrowth might be a potential water quality problem in this system. Higher DO measurements (>5.7 mg l(-1)) might cause the aerobic biodegradation of THMs and HAAs in the system, and thus, low THMs (sampling locations. Results from the observed negative Langelier Saturation Index (LSI) values, higher Ryznar Stability Index (RSI) values, and high Fe3+ concentrations at some pipe-end locations indicate that highly oxidative and corrosive conditions occurred. This reveals that pipe replacement should be considered at these locations. These

    Full Text Available There has been limited knowledge on worker’s exposure to chemicals used in the automotive industries. The purpose of this study is to assess chemical risk and to determine the adequacy of the existing control measures to reduce chemical exposure. A cross sectional survey was conducted in a factory involving installation and servicing of automotive air conditioner units. Qualitative exposure assessment was carried out following the Malaysian Chemical Health Risk Assessment Manual (CHRA. There were 180 employees, 156 workers worked in the production line, which constitutes six work units Tube fin pressed, Brazing, Welding, Final assembly, Piping and Kit II. From the chemical risk evaluation for each work unit, 26 chemical compounds were used. Most of the chemicals were irritants (eye and skin and some were asphyxiants and sensitizers. Based on the work assignment, 93 out of 180 (51.67% of the workers were exposed to chemicals. The highest numbers of workers exposed to chemicals were from the Brazing section (22.22% while the Final Assembly section was the lowest (1.67%. Health survey among the workers showed occurrence of eye irritation, skin irritation, and respiratory irritation, symptoms usually associated with chemical exposure. Using a risk rating matrix, several work process were identified as having ‘significant risk’. For these areas, the workers are at risk of adverse health effects since chemical exposure is not adequately controlled. This study recommends corrective actions be taken in order to control the level of exposure and to provide a safe work environment for workers.

  19. System analysis of energy utilization from waste - evaluation of energy, environment and economy. Case study - Stockholm

    International Nuclear Information System (INIS)

    Energy, environmental, and economic consequences of different management systems for municipal solid waste have been studied in a systems analysis. In the systems analysis, different combinations of incineration, materials recycling of separated plastic and cardboard containers, and biological treatment (anaerobic digestion) of easily degradable organic waste, were studied and also compared to landfilling. In the study a computer model (ORWARE) based on LCA methodology was used. The following parameters were used for evaluating the different waste management options: consumption of energy resources, global warming potential, acidification, eutrophication, photo oxidant formation, heavy metal flows, financial economy and welfare economy, where welfare economy is the sum of financial economy and environmental economy. The study shows that reduced landfilling to the benefit of an increased use of energy and material from the waste is positive, from an environmental and energy as well as economic aspect. This is mainly due to the fact that the choice of waste management method affects processes outside the waste management system, such as production of district heating, electricity, vehicle fuel, plastic, cardboard, and fertiliser. This means that landfilling of energy-rich waste should be avoided as far as possible, both because of the the environmental impact, and because of the low recovery of resources. Incineration should constitute a basis in the waste management system of Stockholm. Once the waste is collected, longer regional transports are of little significance, as long as the transports are carried out in an efficient manner. Comparing materials recycling and incineration, and biological treatment and incineration, no unambiguous conclusions can be drawn. There are benefits and drawbacks associated with all these waste management options. Materials recycling of plastic containers is comparable to incineration from a welfare economic aspect, but gives less

    In many areas where the technical and financial resources are limited, the treatment and disposal of wastewater comprise a problem. With increasing frequency, the wastewater reuse is considered as another alternative for water management alternative. In this way, the wastewater is converted into an added value resource. Treated wastewater infiltration into the soil could be a viable tertiary treatment, especially for small communities where the availability of land is not a problem and the wastewater has not industrial waste contribution and is highly biodegradable. The Experimental Plant of Carrión de los Céspedes (Seville, Spain) develops non-conventional wastewater treatments for small villages. Currently, a project regarding wastewater reutilization for aquifer recharge through a horizontal permeable reactive barrier and a subsequent soil infiltration is being carried out. One of the aspects to be evaluated within this context is the impact on aquifer. Consequently, the main goal of the present study is to assess the effects on the water flow derived from the future recharge activities by using the MIKE-SHE hydrological code. The unsaturated and saturated zones have been integrated in the model, which requires geological, land use, topography, piezometric head, soil and climate data to build up the model. The obtained results from the model show that with the annual recharge volume contributed by the experimental plant (3 m3 or 0.19 L/s) there is no effect in the groundwater flow. A volume of 400 m3/year (25 L/s) would be required to yield a variation in the piezometric head and therefore, in the groundwater flow i.e. a volume about 100 times larger than the estimated is necessary. To calibrate the model, simulated piezometric head values have been compared to the measured field data at a number of locations. In the calibration, the percent error had to be lower than 15 % at each location. Future works concerning groundwater quality and reactive transport

    This study investigated arsenic and lung cancer incidence in a community setting in the Montreal area. Job histories and sociodemographic factors were collected by interview from 857 lung cancer cases, 533 general population controls, and 1,360 controls with other cancers. Chemist-hygienists assessed each subject's life-time occupational exposure to 294 substances. Logistic regressions yielded arsenic/lung cancer odds ratios of 1.1 (95% confidence interval = 0.60, 1.7) based on cancer controls, and 0.82 (95% confidence interval = 0.41, 1.6) based on population controls. Risk did not rise with increasing level or probability of exposure. Worksite studies consistently show lung carcinogenicity from arsenic. Since confounding from other chemicals was well controlled, the most likely explanation is substantially lower exposures than in previous studies. The lack of association in this study demonstrates the need for caution in interpreting negative findings from population-based case-control studies, particularly when exposures are low or rare, as well as the difficulty in generating hypotheses from such studies.

    Globally, ecosystems are subjected to prolonged droughts and extreme heat events, leading to forest die-offs and dominance shifts in vegetation. Some scientists and managers view soil as the main resource to be considered in monitoring ecosystem responses to aridification. As the medium through which precipitation is received, stored, and redistributed for plant use, soil is an important factor in the sensitivity of ecosystems to a drying climate. This study presents a novel approach to evaluating where on a landscape soils may be most sensitive to drying, making them less resilient to disturbance, and where potential future vegetation changes could lead to such disturbance. The drying and devegetation of arid lands can increase wind erosion, contributing to aerosol and dust emissions. This has implications for air quality, human health, and water resources. This approach combines soil data with vegetation simulations, projecting future vegetation change, to create maps of potential areas of concern for soil sensitivity and dust production in a drying climate. Consistent with recent observations, the projections show shifts from grasslands and woodlands to shrublands in much of the southwestern region. An increase in forested area occurs, but shifts in the dominant types and spatial distribution of the forests also are seen. A net increase in desert ecosystems in the region and some changes in alpine and tundra ecosystems are seen. Approximately 124 000 km(2) of soils flagged as "sensitive" are projected to have vegetation change between 2041 and 2050, and 82 927 km(2) of soils may become sensitive because of future vegetation changes. These maps give managers a way to visualize and identify where soils and vegetation should be investigated and monitored for degradation in a drying climate, so restoration and mitigation strategies can be focused in these areas.

    Full Text Available Achieving high competitive advantage through Information and Communication Technologies (ICT has never been easy without proper management and appropriate utilization of ICT resources. Therefore, the statistics suggested that ICT project failures are very common in the organization due to several reasons; it fails to deliver the required objectives of investment, inaccurate budget planning, lack of risk management plan and time overrun are some basic reasons for an ICT project’s failure. To overcome these issues, recently ICT decision makers are emphasizing more on ICT project’s evaluation rather than investment. The practitioner broadly categorized the evaluation techniques in post and pre evaluation methods, which is further divided into measuring the return from financial and non-financial perspectives. The main purpose of this paper is to provide a comparative analysis on ICT investment’s evaluation, their categories based on pre and post evaluation. Thus, the paper offers an extensive literature review that can help ICT decision makers and organizations to better select the evaluation techniques available, where integration of multiple techniques can further improve this process.

    Urban remnant natural area (URNA), located in the urban or suburb area, less disturbed by dwellers in the process of urbanization, is an important part of complex urban ecosystem and provides significant opportunity for urban sustainable development. Despite that there is a considerable amount of scientific researches on the urban nature in urban and suburb area, the comprehensive research of URNA is still rare. After analyzing the concept and value of URNA, this paper presented a methodology for comprehensive evaluation of URNA by adopting methods of document analysis, prior-selection process, analytic hierarchy process and vector resemblance-degree. As a result, the comprehensive evaluation index of URNA includes target level A, rule level B(ecological environment value, ecological recreation value, social culture value, scientific research value), index level C( diversity, singularity, nature, area, stability, recreation, landscape element, aesthetics, history, scientific), and index level D(20 items). Each index weight of comprehensive evaluation system of URNA of Shanghai was confirmed finally.

    2012-01-01

    Full Text Available Problem statement: Public participation has become a vital element of environmental decision-making. Although public participation has grown tremendously in Thailand due to a rising pressure from the public, this practice often fails to solve environmental problems and conflicts. There is a keen for a systematic evaluation of the public participation process to investigate whether the participation process is effective and what works or does not work in this respect. Approach: This study evaluates the effectiveness of the public participation process of the Hin Krut power plant project through an evaluation model developed from relevant literatures. Results: It was found that the public participation process of the case study was not completely effective when tested against the evaluation criteria. The affected people had no chance to present any comments at the very beginning. The public participation process started too late, after a decision had been made and conflicts among stakeholders already occurred. Conclusion: The public participation process is not yet properly established in the Thai context. There is an urgent need to find a working model and conditions of public participation which can assist in resolving environmental problems. Finally, a set of recommendations for improving public participation process are suggested.

    To evaluate the efficacy of engineering controls in reducing worker exposure to metalworking fluids, an evaluation of an enclosure for a machining center during face milling was performed. The enclosure was built around a vertical metal machining center with an attached ventilation system consisting of a 25-cm diameter duct, a fan, and an air-cleaning filter. The evaluation method included using sulfur hexafluoride (SF6) tracer gas to determine the ventilation system's flow rate and capture efficiency, a respirable aerosol monitor (RAM) to identify aerosol leak locations around the enclosure, and smoke tubes and a velometer to evaluate air movement around the outside of the enclosure. Results of the tracer gas evaluation indicated that the control system was approximately 98% efficient at capturing tracer gas released near the spindle of the machining center. This result was not significantly different from 100% efficiency (p = 0.2). The measured SF6 concentration when released directly into the duct had a relative standard deviation of 2.2%; whereas, when releasing SF6 at the spindle, the concentration had a significantly higher relative standard deviation of 7.8% (p = 0.016). This increased variability could be due to a cyclic leakage at a small gap between the upper and lower portion of the enclosure or due to cyclic stagnation. Leakage also was observed with smoke tubes, a velometer, and an aerosol photometer. The tool and fluid motion combined to induce a periodic airflow in and out of the enclosure. These results suggest that tracer gas methods could be used to evaluate enclosure efficiency. However, smoke tubes and aerosol instrumentation such as optical particle counters or aerosol photometers also need to be used to locate leakage from enclosures. PMID:10635544

    Commonly used GIS combination operators such as Boolean conjunction/disjunction and weighted linear combination can be generalized to the ordered weighted averaging (OWA) family of operators. This multicriteria evaluation method allows decision-makers to define a decision strategy on a continuum between pessimistic and optimistic strategies. Recently, OWA has been introduced to GIS-based decision support systems. We propose to extend a previous implementation of OWA with linguistic quantifiers to simplify the definition of decision strategies and to facilitate an exploratory analysis of multiple criteria. The linguistic quantifier-guided OWA procedure is illustrated using a dataset for evaluating residential quality of neighborhoods in London, Ontario.

    Full Text Available

    An instrument to promote the CO2 emission reductions, taking the Kyoto Protocol goal into account, can be the assignment to energy conversion plants of a monetary charge linked to their specific emission intensity. Once the choice of a charge is defined, the next problem is the choice of a strategy to determine the amount of the imposed charge, named Carbon Tax (CT.

    In this paper an analytical procedure for the Carbon Tax evaluation is proposed and applied. This approach is based on the concept of Efficiency Penalty of the energy system, that represents the evaluation of the cost of the exergy destroyed inside the system and the cost of the exergy rejected in the biosphere with the plant wastes; the Efficiency Penalty term is coupled with the evaluation of the Index of CO2 Emission, which connects the amount of the CO2 emitted by the plant with the Second Law efficiency of the plant itself. The evaluated charge on the CO2 emissions is defined as Carbon Exergy Tax (CET. The procedure is applied here to the analysis of a 700 MW combined plant burning fossil fuels in two different configurations: a typical natural gas fired combined plant, and a coal fired combined plant burning coal in a Pressurised Fluidised Bed Combustor (PFBC.

    2012-12-01

    Full Text Available Abstract Background There are numerous applications for Health Information Systems (HIS that support specific tasks in the clinical workflow. The Lean method has been used increasingly to optimize clinical workflows, by removing waste and shortening the delivery cycle time. There are a limited number of studies on Lean applications related to HIS. Therefore, we applied the Lean method to evaluate the clinical processes related to HIS, in order to evaluate its efficiency in removing waste and optimizing the process flow. This paper presents the evaluation findings of these clinical processes, with regards to a critical care information system (CCIS, known as IntelliVue Clinical Information Portfolio (ICIP, and recommends solutions to the problems that were identified during the study. Methods We conducted a case study under actual clinical settings, to investigate how the Lean method can be used to improve the clinical process. We used observations, interviews, and document analysis, to achieve our stated goal. We also applied two tools from the Lean methodology, namely the Value Stream Mapping and the A3 problem-solving tools. We used eVSM software to plot the Value Stream Map and A3 reports. Results We identified a number of problems related to inefficiency and waste in the clinical process, and proposed an improved process model. Conclusions The case study findings show that the Value Stream Mapping and the A3 reports can be used as tools to identify waste and integrate the process steps more efficiently. We also proposed a standardized and improved clinical process model and suggested an integrated information system that combines database and software applications to reduce waste and data redundancy.

  8. Evaluation of Human Resource Needs for a New Nuclear Power Plant: Armenian Case Study

    International Nuclear Information System (INIS)

    Rising expectations of an increased role for nuclear power in providing energy for future national and global sustainable development have become a reality in many Member States of the IAEA. Over the last several years, dozens of Member States have announced plans to embark on or expand nuclear power programmes. Reflecting on these developments, the IAEA has adjusted its priorities to focus more on the nuclear power programmes of newcomers. Specifically, the IAEA has produced publications providing guidance on the development of a national infrastructure for nuclear power (IAEA Nuclear Energy Series No. NG-G-3.1) and on managing human resources in the field of nuclear energy (IAEA Nuclear Energy Series No. NG-G-2.1). Additionally, assistance to eligible Member States through new technical cooperation (TC) projects has been increased, including direct support through on-site assist visits. In 2007-2008, the IAEA carried out a TC project titled 'Feasibility study of nuclear energy development in Armenia: Evaluation of human resource needs in conjunction with new NPP build' (ARM-005). The project analysed the human resource demands required to support work at all stages of the life cycle of a new power unit planned for Armenia. This included drafting proposals for the means, conditions and requirements for development of human resource capabilities needed to carry out the work. This report is intended to complement the previous IAEA publications by providing an in-depth technical consideration into this critical area of human resource development. The report summarizes major findings of the TC project and details the tasks linked to management of the human resources that will be required by a country planning to build a new NPP. Additional guidance on the development of a national nuclear infrastructure can be found in the IAEA publication 'Milestones in the Development of a National Infrastructure for Nuclear Power', IAEA Nuclear Energy Series No. NG-G-3.1.

    Full Text Available In the past few years, there has been an increasing interest in Massive Open Online Courses (MOOCs as a new form of Technology-Enhanced Learning (TEL, in higher education and beyond. Recognizing the limitations of standalone MOOCs, blended MOOCs (bMOOCs that aim at bringing in-class (i.e. face-to-face interactions and online learning components together have emerged as an alternative MOOC model of teaching and learning in a higher education context. In this paper, we present the design, implementation, and evaluation details of a bMOOC course on “Teaching Methodologies” at Fayoum University, Egypt in cooperation with RWTH Aachen University, Germany, provided using the bMOOC platform L2P-bMOOC. In order to gauge the usability and effectiveness of the course, we employed an evaluation approach based on Conole’s 12 dimensions rubrics, ISONORM 9241/110-S as a general usability evaluation, and a custom effectiveness questionnaire reflecting the different MOOC stakeholder perspectives.

    The buildings in our study have been operational for just a short period and most of them are still in an adjustment phase. The findings show that users in all case studies often stressed the positive aspects connected to the newness and the architectural quality of the buildings. The interviews also show that energy efficiency is often regarded as a bonus or side effect that is gladly accepted but not the main criteria for choosing a house. Nonetheless, most residents seemed to appreciate the environmental benefits over time. Several respondents were also more concerned about the environment now than before they moved into or started to work in an energy efficient building, and they also reported more environmentally friendly behaviour. In most of the case studies, concerns were expressed about thermal comfort. Informants often experienced the building as too hot in the summer and/or too cold in the winter. This perceived discomfort caused different types of personal actions, which had a potential to interfere with the concept and the calculated energy balance. In order to improve internal conditions, the users in almost every case intervened with the planned use. They found common and known ways to improving their comfort in the buildings without considering how to optimize the new system. None of the respondents had much prior knowledge of energy efficient buildings before moving in or starting to work in the case study buildings. They did not know what to expect from their new environment, and were unfamiliar with the concepts. Many of the informants complained about a lack of information on systems and insufficient training. The studies also show that the occupants desired to control at least some operational aspects. Despite intermittent difficulties with thermal comfort, the tolerance for the buildings performance appeared to be high throughout all the case studies and many respondents were proud of 'their' buildings. Energy efficient buildings are

    2015-12-15

    A field sampling campaign was implemented to evaluate the variation in air pollutants levels near a highway in Tehran, Iran (Hemmat highway). The field measurements were used to estimate road link-based emission factors for average vehicle fleet. These factors were compared with results of an in tunnel measurement campaign (in Resalat tunnel). Roadside and in-tunnel measurements of carbon monoxide (CO) and size-fractionated particulate matter (PM) were conducted during the field campaign. The concentration gradient diagrams showed exponential decay, which represented a substantial decay, more than 50-80%, in air pollutants level in a distance between 100 and 150meters (m) of the highway. The changes in particle size distribution by distancing from highway were also captured and evaluated. The results showed particle size distribution shifted to larger size particles by distancing from highway. The empirical emission factors were obtained by using the roadside and in tunnel measurements with a hypothetical box model, floating machine model, CALINE4, CT-EMFAC or COPERT. Average CO emission factors were estimated to be in a range of 4 to 12g/km, and those of PM10 were 0.1 to 0.2g/km, depending on traffic conditions. Variations of these emission factors under real working condition with speeds were determined. PMID:26318222

    A wearable sensor system enables continuous and remote health monitoring and is widely considered as the next generation of healthcare technology. The performance, the packet error rate (PER) in particular, of a wearable sensor system may deteriorate due to a number of factors, particularly the interference from the other wearable sensor systems in the vicinity. We systematically evaluate the performance of the wearable sensor system in terms of PER in the presence of such interference in this paper. The factors that affect the performance of the wearable sensor system, such as density, traffic load, and transmission power in a realistic moderate-scale deployment case in hospital are all considered. Simulation results show that with 20% duty cycle, only 68.5% of data transmission can achieve the targeted reliability requirement (PER is less than 0.05) even in the off-peak period in hospital. We then suggest some interference mitigation schemes based on the performance evaluation results in the case study. PMID:26426015

    2012-01-01

    Full Text Available Along with increasing concerns on environmental protection and global warming mitigation, new industrial organization modes such as “Ecoindustrial Park” and “Low Carbon Industrial Park” are emerging. Since ecoindustrial parks and low carbon industrial parks may offer multifaceted benefits to the users, it naturally follows that the sustainability assessment of the industrial parks ought to adopt a multicriteria methodology. In this paper, a multicriteria sustainable evaluation framework is proposed in combination with the life cycle analysis and applied to a low carbon and high end industrial park (LCHE in Beijing, China. Results show that the LCHE industrial park can contribute to both energy-saving and greenhouse gas emission mitigations compared with other industrial parks. In terms of economic performance, although the economic profits are considerable, the investment per constructed area is relatively high. The results of sustainable analysis of the LCHE industrial park can thus shed light on future upgrading of industrial parks.

Rock mass classification schemes such as Rock Mass Rating (RMR), Coal Mine Roof Rating (CMRR), Q-system and Roof Strength Index (RSI) have been used for a range of engineering geological applications, including transport tunnels, "hard rock" mining and underground and open-cut coal mines. Often, rock mass classification schemes have been evaluated on subaerial exposures, where weathering has affected joint characteristics and intact strength. In contrast, the focus of this evaluation of the above classification schemes is an underground coal mine in the Bowen Basin, central Queensland, Australia, 15 km east of the town of Moranbah. Rock mass classification was undertaken at 68 sites across the mine. Both the target coal seam and overlying rock show marked spatial variability in terms of RMR, CMRR and Q, but RSI showed limited sensitivity to changes in rock mass condition. Relationships were developed between different parameters with varying degrees of success. A mine-wide analysis of faulting was undertaken, and compared with in situ stress field and local-scale measurements of joint and cleat. While there are no unequivocal relationships between rock mass classification parameters and faulting, a central graben zone shows heterogeneous rock mass properties. The corollary is that if geological features can be accurately defined by remote sensing technologies, then this can assist in predicting rock mass conditions and risk management ahead of development and construction.

    The Hospital Information system (HIS) is a comprehensive solution that offers complete data integration for different administrative levels in hospitals. To the extent that this system is close to its aim, the efficiency and quality of health care would increase in hospitals. The performance of HIS systems in 13 hospitals in Kerman province that they were evaluated based on four major criteria of ownership, location, education and software design. Seven hospitals were located in the capital city of Kerman province. According to teaching status of hospitals, four were teaching and based on their ownership three were public. The checklist of Iranian ministry of health and medical education, containing 20 indexes were used to evaluate each hospital's HIS system in three main supportive, diagnosis and clinical sectors. Spearman correlation coefficient was used to assess the association between major sectors. The highest score (mean±SD) was observed in laboratory information systems (88.19±13.69), resource management (84.47±8.94), and registration information systems (84.47±18.06); the lowest scores were for telemedicine (45.58±3.86), staff information and timing systems (40±16.64), and decision support systems (23.6±4.97). The total score of HIS software was positively correlated with all its three components. There were strong positive correlations between all three components. The three factors of decision support systems, staff information systems and telemedicine have an important role in providing solutions for non-structured management problems and for leading decision-makers to insights, improving human resource management and solving the problem of access to services. Thus, based on the survey findings, those three factors need to be improved in the Iranian hospital information system. PMID:27357880

    Full Text Available The World-Wide Web provides every internet citizen with access to an abundance of information, but it becomes increasingly difficult to identify the relevant pieces of information. Research in web mining tries to address this problem by applying techniques from data mining and machine learning to web data and documents. Web content mining and web structure mining have important roles in identifying the relevant web page. Relevancy of web page denotes how well a retrieved web page or set of web pages meets the information need of the user. Page Rank, Weighted Page Rank and Hypertext Induced Topic Selection (HITS are existing algorithms which considers only web structure mining. Vector Space Model (VSM, Cover Density Ranking (CDR, Okapi similarity measurement (Okapi and Three-Level Scoring method (TLS are some of existing relevancy score methods which consider only web content mining. In this paper, we propose a new algorithm, Weighted Page with Relevant Rank (WPRR which is blend of both web content mining and web structure mining that demonstrates the relevancy of the page with respect to given query for two different case scenarios. It is shown that WPRR’s performance is better than the existing algorithms.

    It is noticed a significant increase in the development of orbital and airborne sensors that enable the extraction of three-dimensional data. So, it's important the increment of studies about the quality of altimetric values derived from these sensors to verify if the improvements implemented in the acquisition of data may influence the results. In this context, as part of a larger project that aims to evaluate the accuracy of various sensors, this work aims to analysis the planialtimetric accuracy of DEM generated from Cartosat-1 stereo pair. The project was developed for an area near the city of São Sebastião, located in the basin of the North Coast of São Paulo state, in Brasil. The relief in this area is very steep, with a predominance of dense forest vegetation, typical of the Atlantic Forest. All points in this assessment have been established in the field, with the use of single frequency (L1) GNSS receivers, through static relative positioning. In this work it was considered the Brazilian standard specifications (PEC, in Portuguese) for classification of cartographic bases. Results may be considered very good and showed that Cartosat-1 orthoimage presents accuracy equivalent to class B for 1:10.000 scale. The DEM presents altimetric accuracy compatible with class A of the 1:25.000 scale. Results obtained are true for this specific area/study case, but may vary in case different scenes or other studies areas are considered.

  15. Evaluation of Township Competitiveness in China: A Case Study of Zhenjiang City

    Institute of Scientific and Technical Information of China (English)

    2012-01-01

    Based on relevant theories about competitiveness,we establish a set of theoretical evaluation indicator system of township competitiveness,in accordance with the township characteristics. We rank 41 towns in Zhenjiang City in terms of comprehensive competitiveness,using factor analysis method and entropy method. Compared with other towns across the country,we find that the township development in all districts (cities) is highly uneven; the township development within urban district of Zhenjiang City is not so rosy; the township features are not prominent; the number and scale of the township enterprises is not enough; individually-run enterprises never get anywhere. Then,the corresponding countermeasures are put forth for the development of agriculture-based towns and industry-based towns: for agricultural town,it should accelerate the development of modern high-efficiency agriculture,develop characteristic agriculture,and promote quality of agricultural products; for industrial town,it can make full use of the advantages in transport and geographical location,consciously draw on the driving role of urban economy,take actions that suit local circumstances to develop characteristic economy,vigorously develop the private economy and export-oriented economy to enrich people,and strengthen the government service function to create efficient government.

    2008-01-01

    Since the concept of sustainable development emerged in the late 1980s, more and more countries and regions have been utilizing sustainable development as their developing strategy. But decades have passed without any effective methods available to quantitatively assess sustainable development, Since the ecological footprint evaluation method initiated in 1992, it has become popular in quantitative assessment of sustainable development because of its convenience, easy-understanding, and reliability. As one of the biggest coastal cities in north China and the economic center of the Bohai Coastal Region, Tianjin's gross domestic product (GDP) was 369.762 billion yuan in 2005, accounting for 2.0% of the whole nation's GDP The paper analyzes Tianjin's development with the ecological footprint method, and the results show that Tianjin's ecological footprint and biocapacity in 2005 were 2. 507gha/cap and 0.276gha/cap respectively. The ecological deficit was 2.230gha/cap. And from 1980 to 2005, Tianjin's ecological deficit per 104 yuan GDP decreased; while per capita ecological deficit has been tending to increase rapidly in recent years. All these results demonstrate that Tianjin is in a state of unsustainable development.

    Full Text Available Reporting on contributions to community development is one way gold mining companies communicate the expanse and depth of their commitment to social responsibility. These projects are intended to provide the mine-proximate communities with some of the wealth and other benefits generated by mine development in their locales. We raise questions about reporting and evaluation of community development projects undertaken by AngloGold Ashanti in the two communities of Nyakabale and Nyamalembo, near its Geita mining projects in the Lake Victoria goldfields of Tanzania. We use archival data and data obtained from field research conducted during different periods throughout 2005, 2007 and 2010 to compare what the company reports to have done with what is found on the ground. Our findings revealed that the corporate reporting is misleading, ambiguous, and omissive. Much of the effort labeled “community development” benefited the companies directly via infrastructure development, food supplies to the mine cafeteria, and worker health. We argue that, if Corporate Social Responsibility (CSR projects are to be the primary way local people directly benefit from mine development, the relationship between the value of those projects and the wealth taken from the location should be considered, community projects should be well defined and differentiated from company-oriented projects, and community representatives should participate in monitoring the success and impact of community development projects.

    In the last years the usage of solar energy has grown considerably in Romania, as well as in Europe, stimulated by various factors as government programs, green pricing policies, decreasing of photovoltaic components cost etc. Also, the rising demand of using Solar Energy Conversion Systems (SECS) is driven by the desire of individuals or companies to obtain energy from a clean renewable source. In many applications, remote consumers far from other energetic grids can use solar systems more cost-effectively than extending the grid to reach the location. Usually the solar energy is measured or forecast on horizontal surface, but in SECS there is needed the total solar radiation incident on the collector surface, that is oriented in a position that maximize the harvested energy. There are many models that convert the solar radiation from horizontal surface to a tilted surface, but they use empirical coefficients and the accuracy is influenced by different facts as geographical location or sky conditions. Such models were used considering measured values for solar radiation on horizontal plane, in the western part of Romania. Hourly values measured for global solar irradiation on the horizontal plane, diffuse solar irradiation on the horizontal plane and reflected solar irradiation by ground are used to compute the total solar radiation incident on different tilted surfaces. The calculated incident radiation is then compared with the real radiation measured on tilted surface in order to evaluate the performance of the considered conversion models.

    2014-12-01

    Full Text Available Need for a Marine Spatial Data Infrastructure (MSDI as a component of a National Spatial Data Infrastructure (NSDI is widely recognized. An MSDI is relevant not only for hydrographers and government planners, but also for many other sectors which takes interest in marine spatial data, whether they are data users, data providers, or data managers [9]. An MSDI encompasses marine and coastal geographic and business information. For efficient use of Marine Spatial Data, it is necessary to ensure its valid and accessible distribution. A geoportal is a specialized web portal for sharing spatial information at different levels over the Internet. This paper re-examines the implementation of an MSDI and what it means for data custodians and end users. Several geoportals are reviewed (German and Australian to determine their web services functionality, capabilities and the scope to which they support the sharing and reuse of Marine Spatial Data to assist the development of the Croatian MSDI Geoportal. This framework provides a context for better understanding the information bases on spatial data standards and a tool for evaluation of MSDI dissemination - Geoportal.

  20. The Use of Analytical Methods in Evaluation of Coptic Wall Paintings Conservation - A Case Study

    International Nuclear Information System (INIS)

    Egypt has a lot of ancient monasteries and churches, which were decorated with different kinds of wall paintings. Structure of these wall paintings consists of support, plaster and painting layers. Paintings deterioration is primarily due to physicochemical, natural and human factors. The most detrimental factors are bat patches, old varnish and organic waste of birds. All these lead to the gradual disappearance of paintings. Modern technology of conservation is focused on application of new materials for cleaning of wall paintings. Here we report on the use of enzymes, for cleaning surface of coptic wall paintings. Analytical techniques such as particle induced X-ray emission, Fourier transform infrared and optical microscopy were used to evaluate the enzymatic cleaning processes of coptic wall paintings and to identify the chemical composition of red, yellow and white pigments. Particle induced X-ray emission results indicated that there is no change in the chemical composition of the materials and pigments due to enzymatic cleaning. Fourier transform infrared and optical microscopy results confirmed the stability of organic medium before and after treatment of different kind of patches. (author)

    2009-05-01

    We evaluated three exposure models with data obtained from measurements among workers who use"aerosol" solvent products in the vehicle repair industry and with field experiments using these products to simulate the same exposure conditions. The three exposure models were the: 1) homogeneously-mixed-one-box model, 2) multi-zone model, and 3) eddy-diffusion model. Temporally differentiated real-time breathing zone volatile organic compound (VOC) concentration measurements, integrated far-field area samples, and simulated experiments were used in estimating parameters, such as emission rates, diffusivity, and near-field dimensions. We assessed differences in model input requirements and their efficacy for predictive modeling. The One-box model was not able to resemble the temporal profile of exposure concentrations, but it performed well concerning time-weighted exposure over extended time periods. However, this model required an adjustment for spatial concentration gradients. Multi-zone models and diffusion-models may solve this problem. However, we found that the reliable use of both these models requires extensive field data to appropriately define pivotal parameters such as diffusivity or near-field dimensions. We conclude that it is difficult to apply these models for predicting VOC exposures in the workplace. However, for comparative exposure scenarios in life-cycle assessment they may be useful.

    Few interventions addressing early childhood trauma have adequate evidence. The Illinois Birth-to-Three Waiver is a 5-year federal project to reduce trauma and increase permanency for young children. In this article the authors describe the explorative and formative phases, including: (a) developing a well-built research question; (b) working with purveyors of evidence-supported interventions (ESIs); (c) adapting ESIs to a large public child welfare system; (d) developing fidelity measures, assessment data and outcomes; and (e) managing the challenges of implementing a randomized controlled trial. Public and private agency staff work in conjunction with university partners to merge implementation science, program evaluation, and intervention research. The project's theory of change stipulates that working with the triad of birth parent(s), foster parent(s), and focal child is critical to achieving project outcomes. The authors articulate the importance of working closely with an interdisciplinary team to achieve these outcomes, and the challenges associated with the early stages of implementation.

  4. Evaluation of the exploitation of nontraditional water resources-Case study of Yantian District in Shenzhen

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Yantian District in Shenzhen is a water deficient area. Water shortage has become a major obstacle to its further economic progress. Consequently, rational exploitation of nontraditional water resources (NWR) has been naturally adopted to increase local available water volume. The purpose of this paper is to analyse the exploitation of two kinds of NWR, namely wastewater reuse and seawater utilization, in Yantian District, and assess the contribution of each mode to deal with the water crisis. Two different nontraditional water supply systems respectively based on the reclaimed water and sea water were presented. And the effects of each system were evaluated in terms of technology. Economy and environment. The result shows that both wastewater reclamation and reuse (WRR) and direct utilization of seawater (DUS) are of great importance to cope with the tight water resource situation in the district. The data indicate that the fresh water saved by WRR system and DUS system is 29 and 17 million m3/a respectively. Moreover, the BOD. COD, NH3-N and T-P reduced by the WRR system are 870, 2900, 725 and 87 t/a, respectively. Considering the integrated effectiveness, the development of WRR system, which is of specific significance to exploiting new water resource and save natural fresh water supplied from distant water diversion project, is the preferred methods used to solve the water shortage problem in Yantian District and recover the water environment as well as maintain the sustainable development of the city zone.

    Full Text Available The aim of this paper is to evaluate and prioritize the proposed cost-effectiveness criteria in supply chain management using fuzzy multiple attribute decision-making (MADM approach. Over the past few years, the determination of suitable cost-effectiveness criteria in the supply chain has become a key strategic issue. However, the nature of these kinds of decisions is usually complex and unstructured. Many quantitative and qualitative factors must be considered to determine the suitable criteria. As the human decision-making process usually contains fuzziness and vagueness, a hierarchy of MADM model based on fuzzy-sets theory is used in this research. Using a fuzzy analytic hierarchy process (FAHP, the weights of criteria and subcriteria are determined and then the final ranking is determined by technique for order preference by similarity to ideal solution (TOPSIS. Finally, fuzzy TOPSIS (FTOPSIS is employed to compare the results with classic TOPSIS. This paper concludes that the subcriteria in all the items are in the same rank.

    Full Text Available In traditional approach, the land surface temperature (LST is estimated by the permanent or portable ground-based weather stations. Due to the lack of adequate distribution of weather stations, a uniform LST could not be achieved. Todays, With the development of remote sensing from space, satellite data offer the only possibility for measuring LST over the entire globe with sufficiently high temporal resolution and with complete spatially averaged rather than point values. the remote sensing imageries with relatively high spatial and temporal resolution are used as suitable tools to uniformly LST estimation. Time series, generated by remote sensed LST, provide a rich spatial-temporal infrastructure for heat island’s analysis. in this paper, a time series was generated by Landsat8 and Landsat7 satellite images to analysis the changes in the spatial and temporal distribution of the Tehran’s LST. In this process, The Normalized Difference Vegetation Index (NDVI threshold method was applied to extract the LST; then the changes in spatial and temporal distribution of LST over the period 1999 to 2014 were evaluated by the statistical analysis. Finally, the achieved results show the very low temperature regions and the middle temperature regions were reduced by the rate of 0.54% and 5.67% respectively. On the other hand, the high temperature and the very high temperature regions were increased by 3.68% and 0.38% respectively.

    In traditional approach, the land surface temperature (LST) is estimated by the permanent or portable ground-based weather stations. Due to the lack of adequate distribution of weather stations, a uniform LST could not be achieved. Todays, With the development of remote sensing from space, satellite data offer the only possibility for measuring LST over the entire globe with sufficiently high temporal resolution and with complete spatially averaged rather than point values. the remote sensing imageries with relatively high spatial and temporal resolution are used as suitable tools to uniformly LST estimation. Time series, generated by remote sensed LST, provide a rich spatial-temporal infrastructure for heat island's analysis. in this paper, a time series was generated by Landsat8 and Landsat7 satellite images to analysis the changes in the spatial and temporal distribution of the Tehran's LST. In this process, The Normalized Difference Vegetation Index (NDVI) threshold method was applied to extract the LST; then the changes in spatial and temporal distribution of LST over the period 1999 to 2014 were evaluated by the statistical analysis. Finally, the achieved results show the very low temperature regions and the middle temperature regions were reduced by the rate of 0.54% and 5.67% respectively. On the other hand, the high temperature and the very high temperature regions were increased by 3.68% and 0.38% respectively. These results indicate an incremental procedure on the distribution of the hot regions in Tehran in this period. To quantitatively compare urban heat islands (UHI), an index called Urban Heat Island Ratio Index(URI) was calculated. It can reveal the intensity of the UHI within the urban area. The calculation of the index was based on the ratio of UHI area to urban area. The greater the index, the more intense the UHI was.

    Full Text Available Despite their wide use in ornithological surveys, point counts and mist nets follow protocols developed in temperate regions, with little attention to possible modifications for tropical systems. Using these methods on a 3-month basis from December 2009-January 2011 in two forest fragments in southeastern Brazil, we wished to evaluate how long these locations needed to be surveyed with point counts for a relatively complete avifaunal inventory (at least 90% of all species and contacts, and if mist net hourly captures can equally detect numbers of species and individuals. Daily counting with four 20-min points during five consecutive days in a rain forest (MC detected 90% of the estimated species richness after 20 h (60 20-min point counts, while 17 h (51 20-min point counts did not detect 90% of the estimated species richness in a semideciduous forest (IT. The first 5 min of point counting in MC (63% of all species and in IT (65% detected significantly more species than the remaining minutes, but it took 15 min to accumulate 86% of all contacts in both forests. Consecutive 5-day mist netting (~ 9 h/day resulted in 70.5 net-h/m² (MC and 74.8 net-h/m² (IT of sample effort, but 80-85% of the estimated number of species was obtained. Although accumulation curves showed no tendency towards stabilization of the number of observed species, the estimated number of species began to stabilize after the first 20 h in both forests. There was no significant difference in capture rates for both species richness and abundance among hourly net checks, but a trend in which these parameters were highest between the second and fourth checks of the day was observed. A 3-day (43.8 and 63.3 net-h/m² mist netting section was enough to record 90% of the species captured during five days in MC and IT, respectively, while precise enough not to jeopardize species richness estimation. The number of individuals, however, decreased order 34% in MC and 38% in IT under the

    The aim of this study is to analyze spatio-temporal variability in Land Surface Temperature (LST) in and around the city of Zonguldak as a result of the growing urbanization and industrialization during the last decade. Three Landsat 5 data and one Landsat 8 data acquired on different dates were exploited in acquiring LST maps utilizing mono-window algorithm. The outcomes obtained from this study indicate that there exists a significant temperature rise in the region for the time period between 1986 and 2015. Some cross sections were selected in order to examine the relationship between the land use and LST changes in more detail. The mean LST difference between 1986 and 2015 in ERDEMIR iron and steel plant (6.8 °C), forestland (3 °C), city and town centers (4.2 °C), municipal rubbish tip (-3.9 °C), coal dump site (12.2 °C), and power plants' region (7 °C) were presented. In addition, the results indicated that the mean LST difference between forestland and city centers was approximately 5 °C, and the difference between forestland and industrial enterprises was almost 8 °C for all years. Spatio-temporal variability in LST in Zonguldak was examined in that study and due to the increase in LST, policy makers and urban planners should consider LST and urban heat island parameters for sustainable development.

    Full Text Available Uncontrolled urban development that was coincided with the Industrial Revolution, make living in a city faced with new problems that were completely antithetical to sustainable development. To solve this problem, administrators, planners, and urban management in general, have prepared plans for development. Because of their unresponsive to urban neighborhoods, development plans and because of their upward to downward processes, these development projects were incapable of solving problems, and many of them have failed. On the other hand, for better urban governance, participation of all actors in both public and private sector and civil society were essential. In addition, on this level of cooperation, leading to ready all actors for culture governance of democratic were realized. This study investigated the role of community-based management in achieving sustainable urban development deals and has analyzed social stability in four dimensions including cultural, economic, physical and environmental. Study area, was a neighborhood of Tehran, in the area of eight, Narmak. The research was a descriptive - analytical study and collecting information and data were performed in the form of documents and survey. The results suggest that the effects of urban management on stabilizing neighborhoods, in physical and environmental aspects, are quite tangible. However, with regard to social and economic dimensions, this effect was more diminished. Certainly, the role and power of urban management in social and economic dimensions could be obtained more sustainability for Narmak neighborhood.

    Ozone is a strong oxidant and when certain concentrations are reached it has adverse effects on health, vegetation and materials. With the aim of protecting human health and ecosystems, European Directive 2008/50/EC establishes target values for ozone concentrations, to be achieved from 2010 onwards. In our study area, located in southwestern Spain, ozone levels regularly exceed the human health protection threshold defined in the European Directive. Indeed, this threshold was exceeded on 92 days in 2007, despite the fact that the Directive stipulates that it should not be exceeded on more than 25 days per calendar year averaged over three years. It is urgent, therefore, to reduce the current ozone levels, but because ozone is a secondary pollutant, this reduction must necessarily involve limiting the emission of its precursors, primarily nitrogen oxides (NOx) and volatile organic compounds (VOC). During the central months of the year, southwestern Spain is under strong insolation and weak synoptic forcing, promoting the development of sea breezes and mountain-induced winds and creating re-circulations of pollutants. The complex topography of the area induces the formation of vertical layers, into which the pollutants are injected and subjected to long distance transport and compensatory subsidence. The characteristics of these highly complex flows have important effects on the pollutant dispersion. In this study two ozone pollution episodes have been selected to assess the ozone response to reductions in NOx and VOC emissions from industry and traffic. The first corresponds to a typical summer episode, with the development of breezes in an anticyclonic situation with low gradient pressure and high temperatures, while the second episode presents a configuration characteristic of spring or early summer, with a smooth westerly flow and more moderate temperatures. Air pollution studies in complex terrain require the use of high-resolution models to resolve the complex

  2. Comparative Evaluation and Case Studies of Shared-Memory and Data-Parallel Execution Patterns

    Full Text Available Shared‐memory and data‐parallel programming models are two important paradigms for scientific applications. Both models provide high‐level program abstractions, and simple and uniform views of network structures. The common features of the two models significantly simplify program coding and debugging for scientific applications. However, the underlining execution and overhead patterns are significantly different between the two models due to their programming constraints, and due to different and complex structures of interconnection networks and systems which support the two models. We performed this experimental study to present implications and comparisons of execution patterns on two commercial architectures. We implemented a standard electromagnetic simulation program (EM and a linear system solver using the shared‐memory model on the KSR‐1 and the data‐parallel model on the CM‐5. Our objectives are to examine the execution pattern changes required for an implementation transformation between the two models; to study memory access patterns; to address scalability issues; and to investigate relative costs and advantages/disadvantages of using the two models for scientific computations. Our results indicate that the EM program tends to become computation‐intensive in the KSR‐1 shared‐memory system, and memory‐demanding in the CM‐5 data‐parallel system when the systems and the problems are scaled. The EM program, a highly data‐parallel program performed extremely well, and the linear system solver, a highly control‐structured program suffered significantly in the data‐parallel model on the CM‐5. Our study provides further evidence that matching execution patterns of algorithms to parallel architectures would achieve better performance.

  3. Energy and environmental evaluation of municipal facilities: Case study in the province of Barcelona

    International Nuclear Information System (INIS)

    The service sector is extraordinarily important for the European economy, as it accounts for 75% of the GDP. Yet it is also a huge consumer of energy, especially in urban environments. Municipalities have the authority to develop and manage municipal services, and as a result the European Commission drew up the Covenant of Mayors in which the signatory municipalities pledge to reduce their CO2 emissions by 20% of their 1990 rates. Sustainable Energy Action Plans (SEAPs) emerged from this covenant with the goal of analysing the current consumption patterns and compiling the actions that the municipalities should undertake in order to fulfil their pledges. This article focuses on analysing the energy consumption and greenhouse gas emissions of 978 municipal service facilities in the province of Barcelona in the year 2005. The average consumption per facility by surface area is 118.8 kWh/m2. Regarding greenhouse gas emissions, the average annual emissions in the facilities studied in the province of Barcelona were 40.0 kg CO2 eq/m2. - Highlights: • Energy consumption and GHG emissions of 978 municipal facilities are analysed. • The average annual energy consumption per facility is 130 MWh. • The average annual energy consumption per facility by surface area is 118.8 kWh/m2. • The average annual GHG emissions in the facilities studied are 40.0 kg CO2 eq/m2

    Full Text Available Abstract Background Recent whole genome analysis and follow-up studies have identified many new risk variants for coeliac disease (CD, gluten intolerance. The majority of newly associated regions encode candidate genes with a clear functional role in T-cell regulation. Furthermore, the newly discovered risk loci, together with the well established HLA locus, account for less than 50% of the heritability of CD, suggesting that numerous additional loci remain undiscovered. Linkage studies have identified some well-replicated risk regions, most notably chromosome 5q31 and 11q23. Methods We have evaluated six candidate genes in one of these regions (11q23, namely CD3E, CD3D, CD3G, IL10RA, THY1 and IL18, as risk factors for CD using a 2-phase candidate gene approach directed at chromosome 11q. 377 CD cases and 349 ethnically matched controls were used in the initial screening, followed by an extended sample of 171 additional coeliac cases and 536 additional controls. Results Promotor SNPs (-607, -137 in the IL18 gene, which has shown association with several autoimmune diseases, initially suggested association with CD (P IL18-137/-607 also supported this effect, primarily due to one relatively rare haplotype IL18-607C/-137C (P Conclusion Haplotypes of the IL18 promotor region may contribute to CD risk, consistent with this cytokine's role in maintaining inflammation in active CD.

    Full Text Available As the core of the effective financial crisis prevention, enterprise finance crisis prediction has been the focal attention of both theorists and businessmen. Financial crisis predictions need to apply a variety of financial and operating indicators for its analysis. Therefore, a new evaluation model based on nonlinear programming is established, the nature of the model is proved, the detailed solution steps of the model are given, and the significance and algorithm of the model are thoroughly discussed in this study. The proposed model can deal with the case of missing data, and has the good isotonic property and profound theoretical background. In the empirical analysis to predict the financial crisis and through the comparison of the analysis of historical data and the real enterprises with financial crisis, we find that the results are in accordance with the real enterprise financial conditions and the proposed model has a good predictive ability.

    Full Text Available Economics of information has been developing increasingly in economics literature in recent decades. Accordingly, the information plays a crucial role in efficiency of any market particularly capital market which deals more with this issue. As for the importance of information in stock exchange efficiency, the market efficiency is studied under three data sets in three forms including: 1- Information concerning the past prices, 2- All the released information and, 3- General Information and Confidential private information. Given these three types of information, market efficiency is checked in three weak, semi-strong and strong levels, respectively. This paper in order to examine the efficiency in the weak level employs a decomposed pattern with two stochastic and random terms for Top Fifty most active companies (TSE-50 in Tehran stock exchange based on both long and short horizons. The findings demonstrate that the indicator does not have efficiency in long horizon. This is while; the efficiency is verified in short horizon.

    The main purpose of this study was to describe elementary teachers' attitudes and perceptions toward plant science. The secondary purpose was to create an edible plant curriculum as a vehicle for integrating STEM and 21st Century skills into Common Core Content. Results indicate that teachers and STEM coordinators did find the curriculum to be effective in teaching the interdisciplinary standard-based and inquiry based content and skills targeted. Additionally, the curriculum development process produced a hybrid design framework that facilitated the creation of life science content as a vehicle for integrating STEM into common core content. However, several significant barriers will need to be overcome with regard to the teachers', STEM coordinators' and administrators' perception that plant science and nutrition literacy are "special" content activities versus important STEM content.

    International Nuclear Information System (INIS)

    Highlights: • Tiered approach to waste sorting ensures flexibility and facilitates comparison of solid waste composition data. • Food and miscellaneous wastes are the main fractions contributing to the residual household waste. • Separation of food packaging from food leftovers during sorting is not critical for determination of the solid waste composition. - Abstract: Sound waste management and optimisation of resource recovery require reliable data on solid waste generation and composition. In the absence of standardised and commonly accepted waste characterisation methodologies, various approaches have been reported in literature. This limits both comparability and applicability of the results. In this study, a waste sampling and sorting methodology for efficient and statistically robust characterisation of solid waste was introduced. The methodology was applied to residual waste collected from 1442 households distributed among 10 individual sub-areas in three Danish municipalities (both single and multi-family house areas). In total 17 tonnes of waste were sorted into 10–50 waste fractions, organised according to a three-level (tiered approach) facilitating comparison of the waste data between individual sub-areas with different fractionation (waste from one municipality was sorted at “Level III”, e.g. detailed, while the two others were sorted only at “Level I”). The results showed that residual household waste mainly contained food waste (42 ± 5%, mass per wet basis) and miscellaneous combustibles (18 ± 3%, mass per wet basis). The residual household waste generation rate in the study areas was 3–4 kg per person per week. Statistical analyses revealed that the waste composition was independent of variations in the waste generation rate. Both, waste composition and waste generation rates were statistically similar for each of the three municipalities. While the waste generation rates were similar for each of the two housing types (single

  13. Case Study: Design and Performance Evaluation of a Permanent File Archiving System

    Energy Technology Data Exchange (ETDEWEB)

    Linton, L. H.

    1979-01-01

    A common problem confronting many computer installations is the allocation of the limited on-line disk space to the insatiable user demand for this space. When disks become so saturated that the system can no longer function efficiently, some files must be removed. This paper deals with the problem of attempting to optimally select among all the files those which should remain on-line and those which should be archived (information written to tape but directory entry with tape number left on-line). A user access of an archived file automatically spins off a system job to retrieve the file from its tape. An algorithm for selecting files for archiving was designed on the basis of some system performance goals and hypotheses about permanent file usage. An archiving performance analysis program was run periodically to monitor the impact on system performance, the impact on system resources and the accuracy of file selection. Two areas in which archiving might degrade system performance are the following: long waits by interactive users for archived files to become available, and a steep rise in the number of weekly tape mounts due to archived files. An adverse effect of archiving on system resources would be felt if the number of directory entries for archived files or the number of tapes needed to hold archived files increased greatly. Improvements in file selection were studied by characterizing files that either were frequently archived or were never archived and rarely used. 9 figures.

    Full Text Available Energy dispersions for transmission in buildings with highly insulated envelope are mainly due to thermal bridges. And because the energy certification of buildings shall be based on real thermal performance and not on theoretical components, nowadays their incidence on energy saving is relevant. Currently, infrared thermography is considered exclusively as a qualitative tool to detect thermal irregularities in buildings, but thermographic inspection allows not only the localization of thermal bridges, but also the identification of temperature field and, therefore, the quantization of the energy losses through such elements of discontinuities. This approach marks a shift from a qualitative to a quantitative analysis of the thermographic image of a building. The aim of this paper is to study the effect of three different types of thermal bridge, estimated as a percentage increase of the homogeneous wall thermal transmittance. Results are obtained exclusively with thermographic surveys without further information on the wall stratigraphy. Finally, the methodology has been validated by comparing with the results obtained by numerical calculation.

    The structure, function, and physico-chemical properties of many proteins are determined by PTM, being glycosylation the most complex. This study describes how a combination of typical proteomics methods (2-DE) combines with glycomics strategies (HPLC, MALDI-TOF-MS, exoglycosidases sequencing) to yield comprehensive data about single spot-microheterogeneity, providing meaningful information for the detection of disease markers, pharmaceutical industry, antidoping control, etc. Recombinant erythropoietin and its hyperglycosylated analogue darbepoetin-alpha were chosen as showcases because of their relevance in these fields and the analytical challenge they represent. The combined approach yielded good results in terms of sample complexity (mixture glycoforms), reproducibility, sensitivity ( approximately 25 pmoles of glycoprotein/spot), and identification of the underlying protein. Heterogeneity was present in all spots but with a clear tendency; spots proximal to the anode contained the highest amount of tetra-antennary tetra-sialylated glycans, whereas the opposite occurred for spots proximal to the cathode with the majority of the structures being undersialylated. Spot microheterogeneity proved a consequence of the multiple glycosylation sites as they contributed directly to the number of possibilities to account for a discrete charge in a single spot. The interest of this combined glycoproteomics method resides in the efficiency for detecting and quantifying subtle dissimilarities originated from altered ratios of identical glycans including N-acetyl-lactosamine repeats, acetylation, or antigenic epitopes, that do not significantly contribute to the electrophoretic mobility, but affect the glycan microheterogeneity and the potential underlying related functionality.

    Agro-food systems play a significant role in the economies of all nations due to energy use and the resulting environmental consequences. The sustainability of these systems is determined by a multitude of interacting economic, social and environmental factors. Dairy production presents a relevant example of the sustainability trade-offs that occur within such systems. On the one hand, dairy production constitutes an important part of the human diet, but it is also responsible for significant emissions of potent greenhouse gases and other pollutants. In this study, the environmental aspects of pasteurized milk production in Iran were investigated using a life-cycle approach. Three sub-systems, namely feed production, dairy farm and dairy factory, were taken into account to determine how and where Iranian pasteurized milk production might be made more environmentally friendly and energy efficient. The results clearly demonstrate that the feed production stage was the hot spot in pasteurized milk production in terms of energy consumption, environmental burdens and economic costs. The largest share of the total production costs belonged to animal feeds (43%), which were part of the feed production stage. The largest consumers of energy in the production of raw milk were alfalfa (30.3%), concentrate (24%), straw (17.8%) and maize (10.9%) for cows, followed by diesel fuel (6.6%) and electricity (5.6%). The global warming potential for the production of 1000kg of raw milk at the dairy-farm gate was estimated at 457kg CO2,eq. Thus, more than 69% of the total impact at the milk-processing gate resulted from the previous two sub-systems (feed production and dairy farm), with the feed-production stage accounting for the largest fractions of the environmental burdens.

    BACKGROUND: Recent whole genome analysis and follow-up studies have identified many new risk variants for coeliac disease (CD, gluten intolerance). The majority of newly associated regions encode candidate genes with a clear functional role in T-cell regulation. Furthermore, the newly discovered risk loci, together with the well established HLA locus, account for less than 50% of the heritability of CD, suggesting that numerous additional loci remain undiscovered. Linkage studies have identified some well-replicated risk regions, most notably chromosome 5q31 and 11q23. METHODS: We have evaluated six candidate genes in one of these regions (11q23), namely CD3E, CD3D, CD3G, IL10RA, THY1 and IL18, as risk factors for CD using a 2-phase candidate gene approach directed at chromosome 11q. 377 CD cases and 349 ethnically matched controls were used in the initial screening, followed by an extended sample of 171 additional coeliac cases and 536 additional controls. RESULTS: Promotor SNPs (-607, -137) in the IL18 gene, which has shown association with several autoimmune diseases, initially suggested association with CD (P < 0.05). Follow-up analyses of an extended sample supported the same, moderate effect (P < 0.05) for one of these. Haplotype analysis of IL18-137\\/-607 also supported this effect, primarily due to one relatively rare haplotype IL18-607C\\/-137C (P < 0.0001), which was independently associated in two case-control comparisons. This same haplotype has been noted in rheumatoid arthritis. CONCLUSION: Haplotypes of the IL18 promotor region may contribute to CD risk, consistent with this cytokine\\'s role in maintaining inflammation in active CD.

    The incidence of Gastroesophageal reflux disease (GERD) has increased remarkably worldwide. This study focuses on the background features of these patients and evaluates the two GERD sub types; none erosive (NERD) and erosive (ERD). In a case-control study, patients with reflux symptoms who had obtained a total score of 8-18 of the GERD questionnaire were included. Control group consisted of their families with lower scores and no reflux presentations. All demographic features were recorded. Then upper GI endoscopy performed and the cases divided into two sub groups: NERD and ERD. In the next step, all demographic data analyzed for these two subgroups. The data were analyzed using the SPSS software version 21. A number of 210 subjects included in each group (210 patients with GERD and 210 control group) with normal statistical distribution of age and gender. There was a significant relationship between GERD and BMI (P=0.001), eating fatty foods (P=0.0001), lying after meal (P=0.0001), drinking beverages with meal (0.0001), eating spicy food (0.006) and NSAIDs use (P=0.0001). Then the cases divided into two subgroups; NERD (n=146) and ERD (n=64). There were a significant relationship with eating salty-smoky food (P=0.005) and eating spicy food (P=0.011). The difference of BMI between NERD and ERD was remarkable but was not statistically significant. Our results showed that obesity is an important risk factor for GERD. Other possible risk factors such as NSAIDs use and certain foods and wrong habits like lying after meal should be addressed in future longitudinal surveys. PMID:26417402

The accurate identification of plant communities and their distribution are classical tools for mapping and classification of plants. Plants are strongly sensitive against changing environmental conditions. Moreover, Iran has a special position in Asia which has been creating a diverse ecosystem. Close floristic studies are necessary for precise determination of diversity and uniformity. To determine plant species in different vegetation types in Beiran shahr region, modified multi-scale Whittaker plots were constructed. This studied area was about 20000 ha and located in Northwest to Southwest of Iran. Eighty-nine plots were made in different longitude and latitudes. The minimum and maximum heights were 1101 and 2489 m asl., respectively. Within each modified multi-scale plots, each species was explored. Of 608 species, 498 and 97 are belonging to dicotyledons and monocotyledons, and remained 13 species were Pteridophytes. As measured, Therophyte and Champhyte are the dominant and recessive form of life in studied area. Based on species of each plot and subplots, mean Jaccard's coefficient, number of unique species and mean unique species/plot were estimated for each vegetation type. It is obvious that there is a clear correlation between Slopes of the species-log area curve and Mean number of unique species per plot.

    The suitability of a mathematical-model Y = f({Xi}) in serving a purpose whatsoever (should be preset by the function f specific input-to-output variation-rates, i.e.) can be judged beforehand. We thus evaluate here the two apparently similar models: YA = fA(SRi,WRi) = (SRi/WRi) and: YD = fd(SRi,WRi) = ([SRi,WRi] - 1) = (YA - 1), with SRi and WRi representing certain measurable-variables (e.g. the sample S and the working-lab-reference W specific ith-isotopic-abundance-ratios, respectively, for a case as the isotope ratio mass spectrometry (IRMS)). The idea is to ascertain whether fD should represent a better model than fA, specifically, for the well-known IRMS evaluation. The study clarifies that fA and fD should really represent different model-families. For example, the possible variation, eA, of an absolute estimate as the yA (and/ or the risk of running a machine on the basis of the measurement-model fA) should be dictated by the possible Ri-measurement-variations (u_S and u_W) only: eA = (u_S + u_W); i....

    Mindful of the changes to general practice (GP) and GP training over recent years, one vocational training scheme (VTS) decided to thoroughly evaluate its long-running half-day release scheme to decide if it remained fit for purpose, and to plan and implement changes in the light of findings. A literature review was first carried out to ascertain what is known about the contribution that day release and half-day release (HDR) programmes make to GP training. Little has been published on content or evaluation but there is varied experience of incorporating release training into hospital training. This case study reports the views of trainers and trainees on the HDR at Tees Valley Vocational Training Scheme, and the resultant changes made to this HDR programme by the participants. Trainers mostly valued their commitment to HDR small group teaching for their personal development as teachers and for the opportunity to 'keep in touch' with trainees during their hospital posts. Trainees were positive about the HDR programme, but requested more continuity. The plan that evolved is to continue weekly HDR throughout the training programme, keeping trainees in the same small group for three years. In ST1 and ST3 years one programme director per group facilitates each session, maintaining consistency over the year, and liaising with specialists around content. Trainers each teach two sessions in ST2 year. Elective sessions are planned for extended training. PMID:21144173

    Kravchuk, Deborah A.

    With the adoption of the Common Core Learning Standards and the release of the Next Generation Science Standards, New York State students are expected to write in science classes with science writing assessments becoming an indicator of grade level literacy proficiency. The introduction of these assessments raises questions concerning the readiness of teachers to help students learn the skills needed in order to be successful on standardized tests. While such mandates stress the need for incorporating writing into the classroom, few secondary science teachers receive content-specific training in how to teach writing strategies; rather, they often receive the same professional development as their non-science colleagues. This evaluative case study examined how eight secondary science teachers in the Hyde Park Central School District perceived student outcomes as they focused on identifying the challenges encountered and overcome by transferring writing-to-learn (WTL) strategies into the classroom. Targeted professional development (PD) allowed the group of eight secondary science teachers to research WTL strategies, practice them in the classroom, and assess their success through personal and collegial reflection. The results of this study showed a positive correlation between introducing low-stakes writing in the science classroom and increased student understanding of the content presented, that short low-stakes writing prompts helped the students focus on thinking and organizing their thoughts in the science settings (Totten, 2005), and that the secondary science teachers participating in this study perceived the inclusion writing in the classroom to have a positive effect on student outcomes.

    The fundamental difference of the case study and positive research is that one for the formation of theory and the other to verify the theory. Because the object of case study is the 'individual' rather than 'sample' case studies need not start from the theoretical assumptions. All the case studies are to explore, but also to explain, there is not a descriptive case study. Case studies do sampling in the course of the study. Case studies are not require a formal research program and it use theoretical the combination of the subjective interpretation and objective measurement. Case study evaluation can't use statistical concept such as 'reliability' and 'validity'. It can use subjective evaluation: typical and inspiration of the case, trustworthiness, extensibility, accurate and concise records, the reliability of logic, theoretical saturation, the fresh and importance of the results%实证研究的目的是检验理论假说,而案例研究的目的是构建理论。主要以管理学为例,从研究目的、过程、呈现和评价四个方面阐述实证研究与案例研究的区别。

    This article describes an accurate methodology for an operational, economic, and environmental assessment of municipal solid waste collection. The proposed methodological tool uses key performance indicators to evaluate independent operational and economic efficiency and performance of municipal solid waste collection practices. These key performance indicators are then used in life cycle inventories and life cycle impact assessment. Finally, the life cycle assessment environmental profiles provide the environmental assessment. We also report a successful application of this tool through a case study in the Portuguese city of Porto. Preliminary results demonstrate the applicability of the methodological tool to real cases. Some of the findings focus a significant difference between average mixed and selective collection effective distance (2.14 km t(-1); 16.12 km t(-1)), fuel consumption (3.96 L t(-1); 15.37 L t(-1)), crew productivity (0.98 t h(-1) worker(-1); 0.23 t h(-1) worker(-1)), cost (45.90 € t(-1); 241.20 € t(-1)), and global warming impact (19.95 kg CO2eq t(-1); 57.47 kg CO2eq t(-1)). Preliminary results consistently indicate: (a) higher global performance of mixed collection as compared with selective collection; (b) dependency of collection performance, even in urban areas, on the waste generation rate and density; (c) the decline of selective collection performances with decreasing source-separated material density and recycling collection rate; and (d) that the main threats to collection route efficiency are the extensive collection distances, high fuel consumption vehicles, and reduced crew productivity.

  14. Case study: evaluation of continuos blending silos in the cement industry, by the aid of tracer techniques

    International Nuclear Information System (INIS)

    Besides the actual burning process in cement manufacture, particular importance is attached to raw material preparation and homogenization, not only because of the quality of the kiln fed and therefore of the produced cement, but also because of the economy of the kiln operation, which significantly depends on the uniformity of the chemical composition of the material. As a result, the blending process of the cement raw material, before burning, is a basic stage of cement technology production. In this case, the pneumatic homogenization process is studied in a silo with a great storing and processing capacity. The objective is to evaluate the parameters which influence in the continuos operation. The method allows us to determine the optimal blending parameters, through the observation of the movement and distribution of the different fractions of fine dust raw meal, labelled with La-140 as tracer. Changes in blending according to time are discussed as well as the influence of the silo design on the degree of homogenization. It was showed that the silo blending operation has a strong influence on the production of good-quality cement as well as the implications on energy saving

    Min-Ren Yan

    2013-02-01

    Full Text Available High-technology industries provide opportunities for economic growth, but also raise concerns because of their energy-demanding nature. This paper provides an integrated evaluation of both economic benefits and energy efficiency of high-technology industries based on the real data from one of the globally recognized high-technology industrial clusters, the national science parks in Taiwan. A nation-wide industrial Input-Output Analysis is conducted to demonstrate the positive effects of science parks on national economic developments and industrial upgrades. The concept of energy intensity and an energy-efficient economy index are applied to an integrated assessment of the relationship between economic growth and energy consumption. The proposed case study suggests that economic and energy efficiency objectives can be simultaneously achieved by the development of high-technology industries, while three energy policy implications are considered. First, a nation-wide macro viewpoint is needed and high-technology industries should be considered as parts of the national/regional economies by governmental agencies. Second, a proper industrial clustering mechanism and the shared environmental facilities supported by the government, such as planned land and road usage, electricity and water supply, telecommunications system, sewerage system and wastewater treatments, can improve energy efficiency of high-technology industries. Third, the governmental policies on the taxing and management system in science parks would also direct energy-efficient economy of high-technology industries.

Theory testing refers to the critical examination, observation, and evaluation of the 'why' and 'how' of a specified phenomenon in a particular setting. In this paper, we focus on...... the strengths of theory-testing case studies. We specify research paths associated with theory testing in case studies and present a coherent argument for the logic of theoretical development and refinement using case studies. We emphasize different uses of rival explanations and their implications...... for research design. Finally, we discuss the epistemological logic, i.e., the value to larger research programmes, of such studies and, following Lakatos, conclude that the value of theory-testing case studies lies beyond naïve falsification and in their contribution to developing research programmes...

We tried to adopt the fundaments of the seascape concept, based on the thematic elements of landscape ecology and translated into terms fitting with the principles of coastal ecology. The seascape concept is central to our view of the environment and is referred to as an integrated unit (Environmental Unit) resulting from a long multidisciplinary approach, carried out in both the field and the laboratory by an interdisciplinary team of experts. Side Scan Sonar and Multi Beam acoustical data collected in the Marettimo and Ustica Islands (south-western Tyrrhenian Sea))inner shelves, make possible to sketch geomorphological and sedimentological maps, whose details have been tested as deep as 45 m in diving surveys. On the basis of the collected data sets, the inner shelf (0-60 m) has been subdivided into different portions, following the concept of the Environmental Unit (E.U). Every E.U. presents constant morphological and sedimentological features that, probably, can be associated to specified biological communities. In order to find the relationships between physical settings and communities, geological thematic maps are eventually overlaid and fitted to macrobenthic and fishery spatial distribution maps. The result, based on the rule of the Environmental Impact Assessment, puts into evidence the

    Full Text Available Introduction: Participatory evaluation (PE is a hybrid methodology that can be used simultaneously to investigate and act in groups and communities. It can generate new knowledge about reality, but italso allows changes in the participants and their sociocultural context. This research project, developed over three years, aims to find out whether PE processes are useful and appropriate to evaluate community actionsand to generate learning that contribute to the empowerment of people who develop them.Method: The methodological structure of the research process design Participatory Evaluation processes that are applied in three selected communities-cases, over one year. The steering groups in each caseevaluated four dimensions of Community Development Plans: context, evolution, performance and results, using different techniques and group dynamics. Throughout this process, participants identify the acquiredknowledge and this is linked to indicators of empowerment, using questionnaires, content analysis and semi-structured interviews.Results: The development PE process in the three analyzed cases confirmed that PE is a useful strategy to assess participatory community actions of a territory; to report them to the people of the community; andto make shared decisions, about initiatives in order to improve community actions. The obtained results also verify that, throughout PE, there has been learning in the participants.Conclusions: The involvement of community members in the evaluation makes it more useful, fairer and more valid, but also a fourth positive consequence of PE is empowerment. From the process and the resultsof these cases of Participatory Evaluation, we consider that community EP is social transformation.

    Breaking the students into small, collaborative learning groups to solve a meaningful task together is one of the most successful and fully evaluated teaching techniques implemented over the last century. Although there are many ways to accomplish small group learning, a long-standing and consistently successful collaborative class activity is to use the case study teaching strategy. The use of case studies is common in medical schools and law schools, but not so common in the teaching of astronomy. Case studies create meaningful conversations among students and with the professor by focusing on life-like dilemmas to be solved. Case study tasks ask audience members to synthesize several ideas or evaluate scenarios that have not been explicitly presented to them in the lecture or in available readings.

    The Himalaya exhibit dynamic ecological, hydrological, and climatic extremes that magnify the variability and extent of natural hazards, resulting in destruction to both physical and human landscapes. Coupled with poverty, these factors intensify local communities' vulnerability to climate change. This study highlights the Arun watershed in eastern Nepal as a case study to evaluate how local communities in high altitude regions are managing their water for domestic and agricultural needs while coping with extreme events, such as floods and landslides. Remotely-sensed precipitation, snowpack and glacial extent data from the past decade are combined with preliminary results from extensive field-based community surveys in the Arun watershed. The analysis of remotely-sensed data will describe seasonal trends in water availability, glacial lake growth, and the spatial variation of these trends within the basin. These hydrologic changes will be linked to the human survey analysis, which will provide an understanding of locals' perceptions of water challenges and the current water management strategies within the basin. Particular attention will be given to a comparison between the eastern and western tributaries of the Arun River, where the catchments are mainly rain-fed (eastern) versus glacial-fed (western). This contrast will highlight how different hydrologic scenarios evidenced from remote-sensing data motivate diverse human water management responses as defined in field surveys. A particular focus will be given to management decisions related to agriculture expansion and hydropower development. This synthesis of remote-sensing and social research methodologies provides a valuable perspective on coupled human-hydrologic systems.

    Full Text Available The objective of this study was to analyse fruit quality through consumers’ perceptions and their preferences revealed by two panel questionnaires. Among the most common apple cultivars on the Romanian markets, were chosen the ones existing simultaneously and continuously (over two-years, during January-March: ‘Golden Delicious’, ‘Braeburn’, ‘Granny Smith’, ‘Red Delicious’, ‘Jonagold’, ‘Jonathan’, ‘Florina’, ‘Idared’. The consumers’ panel for sensory evaluation was represented by students, who completed two types of questionnaires. Both questionnaires refer to foremost traits for dessert apple, such as fruit appearance (size, shape, color and intrinsic peculiarities (pulp consistency, juiciness, taste, flavor. First questionnaire comprised different scales for the traits (1-3, 1-5 or 1-15, while the second one consisted of the hedonic scale (1-9 for all traits. For commercial appearance of the fruits were highlighted ‘Idared’, ‘Granny Smith’, ‘Braeburn’ and especially ‘Jonagold’. ‘Braeburn’ was distinct by the highest quality taste (average grade 13.9 on the scoring taste scale 1-15 and also for fruit flavor. ‘Granny Smith’, a commercially attractive-looking fruit, received only an average of 6.2 for taste and 2.6 for flavor. ‘Granny Smith’ presented the largest value for the coefficients of variation for taste, this variety being preferred less by female than male tasters. Inconsistency of the market, prices and foreign assortment on Romanian market was illustrated by the lack of statistical correlations between commercial fruit quality and price. The study could provide useful background information for apples breeders, farmers and marketing fruits strategy. The use of different scales for panel evaluation, dependent on the relevance of traits, might be a proper solution for reducing bias. In this case, the 1-15 large scale for apple taste compared with lower ones for other traits

  9. On-site evaluation of percutaneous CT-guided fine needle aspiration of pulmonary lesions. A study of 321 cases

    International Nuclear Information System (INIS)

    Purpose: The aim of this study was to assess the usefulness of having a cytopahologist present during percutaneous CT-guided fine needle aspiration (FNA) of pulmonary lesions. Materials and methods: Three hundred and twenty-one FNAs of lung lesions were performed in 312 patients (218 males, 94 females; age range 20-86 years; means age: 66yrs). Nodule size ranged from 0.5 to 8 cm. The sampling was performed by a radiologist under CT-guidance; the calibre of the needle used was 20-25G. Smears were prepared in the Radiology Department and stained using a quick method by a cytopathologist: the sample adequacy was assessed and, if possible, a preliminary diagnosis was made. An additional FNA was requested if the first aspirate was considered diagnostically inadequate. The diagnostic accuracy was examinated by reviewing the clinical data and by correlating with the histological material and the clinical outcome.Results: Satisfactory diagnostic material was obtained in 275 of the 321 FNA (86%): 231 were malignant (72%), 8 suspicious (3%) and 36 were negative for malignancy (11%). Forty-six of the 321 specimens (14%) were considered inadequate for any diagnostic verification. An additional FNA was performed immediately in 60 cases (19%). Forty-two subjects developed pneumothorax: 21 patients (50%) of these required thoracic drainage. Blood effusion around the lesion site or adjacent to the needle path was observed in 39 patients (12%). Sensitivity was 99%, specificity was 95% and diagnostic accuracy was 99%. Conclusions: CT-guided aspiration cytology can be a safe and fast procedure for lung nodule characterization. On-site immediate evaluation of FNA specimens can be beneficial in determining the adequacy of the aspirate and in providing accurate preliminary diagnoses of the specimens, thus allowing for rapid clinical decisions

    Most countries in sub-Saharan Africa have now adopted integrated community case management (iCCM) of common childhood illnesses as a strategy to improve child health. In March 2014, the iCCM Task Force published an Indicator Guide for Monitoring and Evaluating iCCM: a 'menu' of recommended indicators with globally agreed definitions and methodology, to guide countries in developing robust iCCM monitoring systems. The Indicator Guide was conceived as an evolving document that would incorporate collective experience and learning as iCCM programmes themselves evolve. This article presents findings from two studies that examined the feasibility of collecting the Indicator Guide's 18 routine monitoring indicators with the iCCM monitoring systems that countries currently have in place. We reviewed iCCM monitoring tools, protocols and reports from a purposive sample of 10 countries in sub-Saharan Africa. We developed a scorecard system to assess which of the Indicator Guide's 18 routine monitoring indicators could be calculated with the given monitoring tools, and at which level of the health system the relevant information would be available. We found that the data needed to calculate many of the Indicator Guide's routine monitoring indicators are already being collected through existing monitoring systems, although much of these data are only available at health facility level and not aggregated to district or national levels. Our results highlight challenge of using supervision checklists as a data source, and the need for countries to maintain accurate deployment data for CHWs and CHW supervisors. We suggest that some of the recommended indicators need revising. Routine monitoring will be more feasible, effective and efficient if iCCM programmes focus on a smaller set of high-value indicators that are easy to measure, reliably interpreted and useful both for global and national stakeholders and for frontline health workers themselves.

    Burkitt's lymphoma (BL) is a malignancy of B lymphocytes. The rapid growth rate and frequent systemic spread result in most patients presenting with advanced disease at diagnosis. Cerebrospinal fluid cytology is the gold standard (with very high accuracy) for diagnosing BL central nervous system (CNS) metastasis; however, the low sensitivity of this method limits its clinical applications. Here, we report a case of BL with CNS metastasis. The levels of vascular endothelial growth factor (VEGF)-A and VEGF-C in the serum and cerebrospinal fluid were used to evaluate the status of BL remission and recurrence. Comparisons were made between VEGF and the other risk factors used in evaluating CNS metastasis. Although not in strict accordance, VEGF levels mirrored the disease course. Therefore, VEGF may reflect the status of BL CNS metastasis. Understanding the role of VEGF in CNS metastasis may help to improve the staging and risk classification of BL as well as the investigation of targeted therapy. PMID:25312095

    2015-12-01

    Full Text Available The case fatality ratio (CFR of Ebola virus disease (EVD can vary over time and space for reasons that are not fully understood. This makes it difficult to define the baseline CFRs needed to evaluate treatments in the absence of randomized controls. Here, we investigate whether viremia in EVD patients may be used to evaluate baseline EVD CFRs.We analyzed the laboratory and epidemiological records of patients with EVD confirmed by reverse transcription PCR hospitalized in the Conakry area, Guinea, between 1 March 2014 and 28 February 2015. We used viremia and other variables to model the CFR. Data for 699 EVD patients were analyzed. In the week following symptom onset, mean viremia remained stable, and the CFR increased with viremia, V, from 21% (95% CI 16%-27% for low viremia (V < 104.4 copies/ml to 53% (95% CI 44%-61% for intermediate viremia (104.4 ≤ V < 105.2 copies/ml and 81% (95% CI 75%-87% for high viremia (V ≥ 105.2 copies/ml. Compared to adults (15-44 y old [y.o.], the CFR was larger in young children (0-4 y.o. (odds ratio [OR]: 2.44; 95% CI 1.02-5.86 and older adults (≥ 45 y.o. (OR: 2.84; 95% CI 1.81-4.46 but lower in children (5-14 y.o. (OR: 0.46; 95% CI 0.24-0.86. An order of magnitude increase in mean viremia in cases after July 2014 compared to those before coincided with a 14% increase in the CFR. Our findings come from a large hospital-based study in Conakry and may not be generalizable to settings with different case profiles, such as with individuals who never sought care.Viremia in EVD patients was a strong predictor of death that partly explained variations in CFR in the study population. This study provides baseline CFRs by viremia group, which allow appropriate adjustment when estimating efficacy in treatment studies. In randomized controlled trials, stratifying analysis on viremia groups could reduce sample size requirements by 25%. We hypothesize that monitoring the viremia of hospitalized patients may inform the

  1. Evaluation for Use Efficiency of Agricultural Resources in Grain Production: A Case Study of Changshu, Taihe and Ansai in China

    Institute of Scientific and Technical Information of China (English)

    SONG Wei; CHEN Baiming; CHEN Xiwei

    2009-01-01

    This paper aims to establish an index system for evaluation of agricultural resources use efficiency (ARUE) in grain production and discuss the causes of low efficiency and high consumption of agricultural resources in Changshu of Jiangsu Province, Taihe of Jiangxi Province and Ausai of Shaanxi Province in China by analyzing the data about meteorology, soil, water consumption and grain production. Agro-ecological Zone (AEZ) method was adopted to calculate the potential productivity, and synthetically multivariate equation was used to evaluate the ARUE of study areas. This paper can be concluded as: 1) the agricultural resources in grain production can be classified into five categories, i.e., climatic resources, water resources, land resources, biological resources and assistant resources, and 15 indexes were selected to evaluate their use efficiency in grain production; 2) the values of ARUE in grain production are 0.5868, 0.6368 and 0.5390 respectively in Changshu, Taihe and Ansai; and 3) Changshu ranks the highest among the three study areas in terms of the use efficiency of climatic resources and biological resources (evaluation values are 0.0277 and 0.1530), but Taihe tops the three in terms of the use efficiency of water resources, land resources and assistant resources (evaluation values are 0.0502, 0.2945 and 0.1379 respectively). However, the ARUE remains always low in Ansai for all the resources. The inefficiencies are caused by poor grain revenue in Changshu, deficient agriculture investments in Taihe and unfavorable natural conditions in Ansai.

    Theory-based evaluation (TBE) is an effectiveness assessment technique that critically analyses the theory underlying an intervention. Whilst its use has been widely reported in the area of social programmes, it is less applied in the field of energy and climate change policy evaluations. This paper reports a recent study that has evaluated the effectiveness of the national biofuel policy (NBP) for the transport sector in Malaysia by adapting a TBE approach. Three evaluation criteria were derived from the official goals of the NBP, those are (i) improve sustainability and environmental friendliness, (ii) reduce fossil fuel dependency, and (iii) enhance stakeholders' welfare. The policy theory underlying the NBP has been reconstructed through critical examination of the policy and regulatory documents followed by a rigorous appraisal of the causal link within the policy theory through the application of scientific knowledge. This study has identified several weaknesses in the policy framework that may engender the policy to be ineffective. Experiences with the use of a TBE approach for policy evaluations are also shared in this report. PMID:25898073

    To determine whether MRI allows safe and accurate guidance for biopsies of renal masses. Between May 2010 and September 2013, 26 patients (15 men and 11 women) with 26 renal masses underwent MRI-guided percutaneous biopsy. For each patient, we retrospectively collected the epidemiological, procedural and histopathological data. Mean size of tumour was 3.6 cm (range 0.6 - 9 cm). Mean procedure time was 48 minutes (range 37 - 70 min). Malignancy was found in the percutaneous samples in 81 % (21/26) of the masses. All these cases were considered as true positive biopsies. Benignity was found in the percutaneous samples in 5/26 (19 %) of the masses but was confirmed only in 3 cases. The other 2 cases included one false negative case and one undetermined biopsy, as patient was lost to follow-up. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy of this study were 95.4 %, 100 %, 100 %, 75 % and 96 %, respectively MRI-guidance is safe and accurate to target renal masses.

    A case study was conducted, using dibutyl phthalate (DBP), to explore an approach to using toxicogenomic data in risk assessment. The toxicity and toxicogenomic data sets relative to DBP-related male reproductive developmental outcomes were considered conjointly to derive information about mode and mechanism of action. In this manuscript, we describe the case study evaluation of the toxicological database for DBP, focusing on identifying the full spectrum of male reproductive developmental effects. The data were assessed to 1) evaluate low dose and low incidence findings and 2) identify male reproductive toxicity endpoints without well-established modes of action (MOAs). These efforts led to the characterization of data gaps and research needs for the toxicity and toxicogenomic studies in a risk assessment context. Further, the identification of endpoints with unexplained MOAs in the toxicity data set was useful in the subsequent evaluation of the mechanistic information that the toxicogenomic data set evaluation could provide. The extensive analysis of the toxicology data set within the MOA context provided a resource of information for DBP in attempts to hypothesize MOAs (for endpoints without a well-established MOA) and to phenotypically anchor toxicogenomic and other mechanistic data both to toxicity endpoints and to available toxicogenomic data. This case study serves as an example of the steps that can be taken to develop a toxicological data source for a risk assessment, both in general and especially for risk assessments that include toxicogenomic data.

    The main objective of this study was to evaluate the suitability and select the most appropriate areas for building campgrounds in Kuerdening, China. To achieve this aim, AHP and GIS-based weighted overlay methods were adopted. AHP was used to determine the weights of the indexes, and ArcGIS 10 was used to calculate and map the campground suitability. In pursuit of minimum environmental effects and sustainable development, this paper identifies four factors to evaluate the suitability of areas for building campgrounds: natural environment condition, landscape condition, safety condition and infrastructure condition. The final outcome of this studywas the suitability map for building campgrounds. This research not only provides a theoretical guide for the construction of campgrounds in this area but also provides a scientific and efficientworkflow to evaluate the appropriateness of other areas. The result is reasonable and operable for camping facilities development and also useful for managers and planners working in local governments as well as investors.

    Full Text Available Assessment systems are necessary in the present age with dramatic changes in management knowledge. Thus, lack of assessment systems in different sectors of an organization to evaluate resources, staffs, strategies and objectives signs for presence of illness in the organization. Organizations are always involved with dynamic markets which require speed, compatibility and alignment as key procedures for achievement of competitive advantages. Any organization needs an evaluation system to be aware of its activities utility in complex and dynamic environments. On the other hand, lack of control and evaluation systems means imbalance relationships in internal and external environments of organization which leads to senility or death of organization. Since evaluation of organizations is done to realize weaknesses and strengths, to increase abilities and competencies and to make managerial decisions; this paper seeks to assess Iranian steel firms using principles of strategy-focused organization. So far, key success factors in organizations have been studied by researchers. However, this study focuses on principles of strategy-focused organization. These principles are considered as independent variables. The dependent variables of the present research are performance results. To conduct the research, the questionnaire is used and distributed in the statistical sample including a number of managers in steel firms.

    Carbon dioxide Capture and Storage techniques (CCS) are one of the effective measures for reduction Carbon dioxide emissions to the atmosphere to mitigate the global warming. Among the Carbon dioxide geological storage options, deep saline aquifers offer the largest storage potential and are widely distributed throughout the Earth. Implementation of carbon dioxide capture and geological storage to reduce greenhouse gas emissions requires carbon dioxide storage capacity in deep saline aquifers. The storage capacity estimation depends on the storage trapping mechanisms and the availability, resolution and certainty of data. There are five different types of trapping mechanisms in deep saline aquifers namely structural and stratigraphic trapping, residual gas trapping, solubility trapping, mineral trapping and hydrodynamic trapping in which storage capacity by solubility trapping is the largest. The carbon dioxide storage capacities in deep saline aquifer can be evaluated by the method recommended by Carbon Sequestration Leadership Forum (CSLF), which mainly depends on the area of study area, thickness and porosity of sandstone, density and carbon dioxide content (mass fraction) in formation water at initial and saturated state. Hydrogeological parameters in aquifer are uncertainty because of uncertainty of measurement and the spatial variety, which leads evaluation uncertainty of carbon dioxide storage capacity. In this paper, acceptance of evaluated carbon dioxide storage capacity in deep saline aquifer caused by hydrological parameters was discussed based on geostatistical methods and stochastic simulation. The stratum named Yaojialing group in the center depressed area of Songliao Basin was chosen as study area because of the rich data. The porosity of sandstone, thickness ration of sandstone to stratum and the total dissolved solid in formation water were regarded as the main source of the uncertainty of carbon dioxide storage capacity evaluation in deep saline

    Despite the burgeoning scientific literature examining the sluggish cognitive tempo (SCT) construct, very little is known about the clinical presentation of SCT. In clinical cases where SCT is suspected, it is critical to carefully assess not only for attention-deficit/hyperactivity disorder (ADHD) but also for other comorbidities that may account for the SCT-related behaviors, especially internalizing symptoms and sleep problems. The current case study provides a clinical description of SCT in a 7-year-old girl, offering a real-life portrait of SCT while also providing an opportunity to qualitatively differentiate between SCT and ADHD, other psychopathologies (e.g. depression, anxiety), and potentially related domains of functioning (e.g. sleep, executive functioning [EF]). "Jessica" was described by herself, parents, and teacher as being much slower than her peers in completing schoolwork, despite standardized testing showing Jessica to have above average intelligence and academic achievement. Jessica's parents completed rating scales indicating high levels of SCT symptoms and daytime sleepiness, as well as mildly elevated EF deficits. More research is needed to determine how to best conceptualize, assess, and treat SCT, and Jessica's case underscores the importance of further work in this area. PMID:25326531

    At the DOE Hanford Site, contaminants were discharged to the subsurface through engineered waste sites in the Hanford Central Plateau. Additional waste was released through waste storage tank leaks. Much of the contaminant inventory is still present within the unsaturated vadose zone sediments. The nature and extent of future groundwater contaminant plumes and the growth or decline of current groundwater plumes beneath the Hanford Central Plateau are a function of the contaminant flux from the vadose zone to the groundwater. In general, contaminant transport is slow through the vadose zone and it is difficult to directly measure contaminant flux in the vadose zone. Predictive analysis, supported by site characterization and monitoring data, was applied using a structured, systems-based approach to estimate the future contaminant flux to groundwater in support of remediation decisions for the vadose zone and groundwater (Truex and Carroll 2013). The SX Tank Farm was used as a case study because of the existing contaminant inventory in the vadose zone, observations of elevated moisture content in portions of the vadose zone, presence of a limited-extent groundwater plume, and the relatively large amount and wide variety of data available for the site. Although the SX Tank Farm case study is most representative of conditions at tank farm sites, the study has elements that are also relevant to other types of disposal sites in the Hanford Central Plateau.

    Full Text Available Introduction: Evaluation is an important factor in productivity context, and acts as a control system for other areas of productivity. Hospitals are large organizations incurring heavy expenses in every country. The level of efficiency in a hospital is a good criterion to understand how hospitals consume their resources. The goal of this research was to determine relative efficiency of 13 public hospitals in Yazd province by using integrated DEA, BSC and SERVQUAL model. Methods: In this study, relative efficiency of 13 public hospitals of Yazd province was calculated using data envelopment analysis technique(DEA and balanced score card and servqual. BSC was used as a tool for designing of performance evaluation indexes, while DEA was used as a tool of evaluating performance and ranking. Results: The mean relative efficiency of hospitals under study was about 0.945 in the Persian calendar year 2008-9. The efficiency levels of nine hospitals were borderline and the efficiency of four hospitals was less than 1. Hospital no.3 had the highest efficiency levels and hospital no.10 had the lowest efficiency level. Conclusion: In this stage, on the basis of references presented by the DEA model, solutions for increasing the quality performance levels of inefficient hospitals in fourth dimensions were determined and some suggestions were proposed. Although all performance indices of the inefficient hospitals need to be addressed, priorities have to be determined by the respective managers.

    Full Text Available With Chinese language gaining more and more popularity among Slovenian students and with the growing numbers of learners of Chinese as a foreign language in Slovenia and elsewhere it is crucial to find an approach that will lead to high quality and long-term knowledge of Chinese and that will motivate learners to continue learning. We can speak of two basic approaches to teaching Chinese vocabulary: the approach that first introduces pronunciation and the approach that simultaneously introduces pronunciation and character. The key question that arises is which of the two approaches leads to high quality and long-term knowledge? To answer the question an experimental case study was carried out at Ljubljana’s Faculty of Arts in the academic year 2011/2012. The case study showed that the approach that simultaneously introduces pronunciation and character and is based on the key principles of constructivist learning theory had beneficial effects on the students in terms of motivation and quality of knowledge of Chinese vocabulary.

    With urban population growing and urban sprawling, urban ecological environment problems appear. Study on spatiotemporal characteristics of urban sprawl and its impact on ecological environment is useful for ecological civilization construction. Although a lot of work has been conducted on urban sprawl and its impact on ecological environment, resolution of images to extract urban boundary was relatively coarse and most studies only focused on certain indicators of ecological environment, rather than comprehensive evaluation of urban ecological environmental impact. In this study, high-resolution remote sensing images of Beijing from aerial photography in 2002 and 2013 respectively are employed to extract urban boundary with manual interpretation. Fractional Vegetation Coverage (FVC), Water Density (WD), Impervious Surfaces Coverage (ISC), Net Primary Production (NPP), and Land Surface Temperature (LST) are adopted to represent ecological environment. The ecological environment indicators are measured with some general algorithms by combining Landsat images, GIS data and metrological data of 243 day, 2001 and 244 day, 2013. In order to evaluate the impact of urban sprawl on ecological environment, pseudo changes due to metrological variation and other noise in this time period are removed after images calibration. The impact of urban sprawl on ecological environment is evaluated at different scales of urban extent, Beijing ring road and watershed. Results show that Beijing had been undergoing a rapid urbanization from 2002 to 2013, with urban area increase from 600 square kilometres to 987 square kilometres. All ecological environment indicators except LST became terrible in urban sprawl region, with carbon reduction of approximate 40508 tons. The Beiyun River watershed of Beijing degraded seriously since ISC increased to 0.59. Gratifyingly, ecological environment indicators including NDVI, NPP, and LST inside of 4th Ring Road became well.

    The evaluation of classroom-based educational interventions is fraught with tensions, the most critical of which is choosing between focusing the inquiry on measuring the effects of treatment or in proximately utilizing the data to improve practice. This paper attempted to achieve both goals through the use of intervention-oriented evaluation of a professional development program intended to diagnose and correct students' misconceptions of climate change. Data was gathered, monitored and analyzed in three stages of a time-series design: the baseline, treatment and follow-up stages. The evaluation itself was the 'intervention' such that the data was allowed to 'contaminate' the treatment. This was achieved through giving the teacher unimpeded access to the collected information and to introduce midcourse corrections as she saw fit to her instruction. Results showed a significant development in students' conceptual understanding only after the teacher's decision to use direct and explicit refutation of misconceptions. Due to the accessibility of feedback, it was possible to locate specifically at which point in the process that the intervention was most effective. The efficacy of the intervention was then measured through comparing the scores across the three research stages. The inclusion of a comparison group to the design is recommended for future studies.

    Full Text Available The main objective of this study was to evaluate the suitability and select the most appropriate areas for building campgrounds in Kuerdening, China. To achieve this aim, AHP and GIS-based weighted overlay methods were adopted. AHP was used to determine the weights of the indexes, and ArcGIS 10 was used to calculate and map the campground suitability. In pursuit of minimum environmental effects and sustainable development, this paper identifies four factors to evaluate the suitability of areas for building campgrounds: natural environment condition, landscape condition, safety condition and infrastructure condition. The final outcome of this studywas the suitability map for building campgrounds. This research not only provides a theoretical guide for the construction of campgrounds in this area but also provides a scientific and efficientworkflow to evaluate the appropriateness of other areas. The result is reasonable and operable for camping facilities development and also useful for managers and planners working in local governments as well as investors.

The main findings of this study show that, in practice, intercultural bilingual indigenous education has not transcended the bilingual dimension (the indigenous language teaching. Interculturalism is not yet clearly integrated in the speech nor in the educational practice of the studied school. The EIB implementation is still limited and responds to sociocultural, linguistic, political, educational and teacher training conditions that characterize the local educational context and are not favorable to enhance the effective implementation of the EIB in the primary school.

  9. Evaluation of the long-term power generation mix: The case study of South Korea's energy policy

    International Nuclear Information System (INIS)

    This paper presents a practical portfolio model for the long-term power generation mix problem. The proposed model optimizes the power generation mix by striking a trade-off between the expected cost of power generation and its variability. We use Monte Carlo simulation techniques to consider the uncertainty associated with future electricity demand, fuel prices and their correlations, and the capital costs of power plants. Unlike in the case of conventional power generation mix models, we employ CVaR (Conditional Value-at-Risk) in designing variability to consider events that are rare but enormously expensive. A comprehensive analysis on South Korea's generation policy using the portfolio model shows that a large annual cost is additionally charged to substitute a portion of nuclear energy with other alternatives. Nonetheless, if Korea has to reduce its dependency on nuclear energy because of undermined social receptivity from the Fukushima disaster, it turns out that LNG or coal could be a secure candidate from an economic perspective. - Author-Highlights: • We develop a stochastic optimization model for long-term power generation mix. • Monte Carlo sampling method and scenario trees are used to solve the model. • The model is verified using the data provided by Korean government. • We evaluate Korea's existing nuclear expansion policy. • We analyze the cost of replacing nuclear energy with others in South Korea

    Large volumes of wastewater disposal capacity will be required for the production of bitumen at the Long Lake Project, located in northeastern Alberta. An unconsolidated sand aquifer is the target formation for disposal. An evaluation of two disposal well designs, perforated casing (standard oil and gas approach), and wire-wound telescopic screen (standard water well approach) was performed. Skin, transmissivity and storability were the hydraulic parameters quantified. Full superposition type curves were used to conduct the transient analysis, along with the use of pressure derivative data. The results from the injection tests revealed that the sand aquifer at the Long Lake Project had suitable aquifer disposal capacity. The test results also revealed that clogging takes place in the vicinity of the wellbore, probably because of suspended solids in the injection water and the degassing effects. The water well design, as opposed to the standard oilfields well, makes provision for less costly re-development during operations, something that might be required if clogging problems occur. 3 refs., 8 figs.

    Water quality evaluation is an important issue in environmental management. Various methods have been used to evaluate the quality of surface water and groundwater. However, all previous studies have used different evaluation models for surface water and groundwater, and the models must be recalibrated due to changes in monitoring indicators in each evaluation. Water quality managers would benefit from a universal and effective model based on a simple expression that would be suitable for all cases of surface water and groundwater, and which could therefore serve as a standard method for a region or country. To meet this requirement, we attempted to develop a universal calibrated model based on the radial basis function neural network. In the new model, the units and values of the evaluation indicators for surface water and groundwater are normalized simultaneously to make the data directly comparable. The model's training inputs comprise the normalized value in each of a water quality indicator's grades (e.g., the nitrate contents defined in a regulatory standard for grades I to V) for all evaluation indicators. The central vector of the Gaussian function is used as the average of the evaluation indicators' normalized standard values for the five grades. The final calibrated model is expressed as an equation rather than in a programming language, and is therefore easier to use. We used the model in a Chinese case study, and found that the model was feasible (it compared well with the results of other models) and simple to use for the evaluation of surface water and groundwater quality.

    2004-01-01

    Japan ranks fifth in the world for the number of large dams. Environmental impacts of large dams are known, such as enormous losses of water or disruption of fish spawning, however, impacts of the dams on their up streams are functions of topography of the up stream. Haizuka Dam is located in Hiroshima Prefecture, Japan and its implementation will start in 2006. This large dam influences its up stream through dam making activities, which occurs in order and with different spatial presences that were categorized into chronological and spatial impacts. In this case study, spatial impacts were further divided into horizontal and vertical ones. The horizontal impacts were identified as new roads, diversion tunnel, dam lake, and submerged cultivated land, while vertical impacts were recognized as submerged historical monuments, slope protections, dam body, and deforested area in the reservoir. There were convergences of spatial and temporal impacts, however, the extent of the impacts was limited to the lake boundary.

  18. Environmental Assessment of a Waste Incineration Tax. Case Study and Evaluation of a Framework for Strategic Environmental Assessment

    International Nuclear Information System (INIS)

    A framework for Strategic Environmental Assessment (SEA) is tested in a case study on a proposed waste incineration tax. Also included is testing of developed methods for valuation and site-dependent life cycle impact assessment. The results indicate that although a suggested waste incineration tax of 400 SEK/ton is likely to lead to environmental improvements, these are small compared to the potential improvements as shown in more visionary scenarios. In order to go in this direction a waste incineration tax based on the content of fossil carbon in the waste would be useful. The framework for SEA includes several different pathways. These have different advantages and disadvantages and provide different types of information. It is therefore suggested that they largely complement each other and that the choice of methods should be done in relation to the function of the SEA and the questions asked.

    International Nuclear Information System (INIS)

    This paper explores people's preferences for a Built in Photovoltaic (BIPV) renewable energy system to be integrated into housing construction. A novel methodology was developed, to study the case of Northern Cyprus, for better understanding of possibilities that abound in BIPV integration. The methodology incorporates Building Information Modeling (BIM) as a real-time design and economic assessment tool for BIPV choices. This serves to benefit both the construction companies and potential house owners in their decision-making. In addition, it uses a Contingent Valuation (CV) method to assess the Willingness to Pay (WTP) and the Willingness to Accept (WTA) compensation. The results indicate that the capital cost of PV is not instrumental in choice, and a lower feed-in tariff could be acceptable

  2. 46, XX male: a case study of clinical, hormonal and molecular cytogenetic evaluation of sex development disorder

    International Nuclear Information System (INIS)

    Disorders of sex development (DSD) create medical and social dilemma. Maleness with XX genotype is a rare genetic condition affecting one in 24,000 new-born males. The XX male syndrome is a varied condition characterized by a spectrum of clinical presentation. ranging from normal male genitalia to ambiguous sex. Chromosomal anomalies are important cause of lack of development in secondary sexual characteristics, delayed puberty, miscarriage, infertility and other associated problems. An individual having ambiguous sex may have lifelong impact on social, psychological and sexual functions. The present case study describes the hormonal, clinical and molecular cytogenetics data of sex development disorders in a patient who was phenotypically male but cytogenetic analysis revealed 46.XX.

    The most conspicuous erosional features associated with constricted bedrock channel reaches and knickpoints are potholes. The presence and morphology of potholes have been attributed to a number of factors by earlier researchers. Amongst these factors, the role of substrate rock properties has received very little quantitative attention. The main objective of this study is to quantitatively evaluate the physical properties of bedrock in order to test the possible influences of rock properties on the occurrence and morphology of potholes. The area selected for this study is a large scabland area developed by the Indrayani river at Shelarwadi near Pune. This site is ideally suited for the study since it is featured by wide straths, multiple inner channels and several hundred potholes. A transect-based quadrat method was used in this study. Within each quadrat, the pothole dimensions, the joint length, joint direction, the rock mass strength and the distance from active channel were measured. The analysis reveals a weak correlation between pothole size and rock properties. The distance from the active channel emerges as the most significant factor, suggesting that the hydraulics of flows is the key factor and substrate characteristics play only a secondary role.

    Full Text Available This paper deals with the problem of multi-criteria evaluation of four management strategies for Fruška Gora National Park. The criteria set was defined in ac­cordance with the IUCN guidelines for management of national parks. Four strategies were evaluated by testing preference intensities for each alternative with the respect to each cri­terion. Alternatives with preference above the approval threshold were approved, and a multi-criteria approval matrix was generated. According to the matrix, the most suitable management strategy was identified. It implies an intense protection of natural resources and landscape diversity in the national park by applying bio-engineering measures. This illustrative example proved that multi-criteria approval can be considered as a good deci­sion support tool when there is no need for a deeper insight into cardinal values of criteria weights and alternatives, or if the decision maker has to select few from many of alterna­tives to reduce the decision problem. For a more precise analysis, it is recommended to combine multi-criteria approval with other decision support tools, and future studies might deal with this problem in order to define an alternative framework for decision making in landscape management.

    Full Text Available Abstract Background A considerable amount of resource allocation decisions take place daily at the point of the clinical encounter; especially in primary care, where 80 percent of health problems are managed. Ignoring economic evaluation evidence in individual clinical decision-making may have a broad impact on the efficiency of health services. To date, almost all studies on the use of economic evaluation in decision-making used a quantitative approach, and few investigated decision-making at the clinical level. An important question is whether economic evaluations affect clinical practice. The project is an intervention research study designed to understand the role of economic evaluation in the decision-making process of family physicians (FPs. The contributions of the project will be from the perspective of Pierre Bourdieu's sociological theory. Methods/design A qualitative research strategy is proposed. We will conduct an embedded multiple-case study design. Ten case studies will be performed. The FPs will be the unit of analysis. The sampling strategies will be directed towards theoretical generalization. The 10 selected cases will be intended to reflect a diversity of FPs. There will be two embedded units of analysis: FPs (micro-level of analysis and field of family medicine (macro-level of analysis. The division of the determinants of practice/behaviour into two groups, corresponding to the macro-structural level and the micro-individual level, is the basis for Bourdieu's mode of analysis. The sources of data collection for the micro-level analysis will be 10 life history interviews with FPs, documents and observational evidence. The sources of data collection for the macro-level analysis will be documents and 9 open-ended, focused interviews with key informants from medical associations and academic institutions. The analytic induction approach to data analysis will be used. A list of codes will be generated based on both the original

  6. Evaluation of environmental policy instruments - a case study of the Finnish pulp and paper and chemical industries

    International Nuclear Information System (INIS)

    This research-based evaluation of environmental policy Instruments in Finland is focussed on regulatory instruments based on the Water Act, the Air Pollution Control Act and the Chemicals Act, on electricity taxation and on voluntary environmental management systems. The examined policy instruments have had several positive effects. They have directed major industrial point source polluters towards solving environmental problems. The transparency has been an important factor ensuring the success of the policy instruments and in avoiding the regulatory capture that could have thrived in a system largely based on negotiations between operators and authorities. The transparency has made it easy for Finnish firms to adopt environmental management systems and an open attitude to environmental reporting. The permit conditions have not directly resulted in innovations, but they have contributed to the diffusion of end-of-pipe technology and have contributed to innovations by expanding the market for environmentally better technical solutions. The permit systems have also indirectly contributed to innovations by creating a demand for environmental experts and environmental education. Networks have clearly developed as a consequence of and in response to regulatory instruments. These networks appear to have had their greatest significance prior to the permit procedures. The trend has been towards a greater emphasis of the communication in the networks prior to the presentation of an application in order to ensure a smoothly functioning permit process. In the networks contributing to innovations and the diffusion of innovations authorities have largely been outsiders, except when an innovation has become a de facto standard for permit conditions. The different kind of effects, the complexity of consequences and the uncertainties with respect to causes and effects mean that studies aiming at evaluating the overall worth and merit of an environmental policy instrument should

    Background. To investigate the safety and efficacy of superselective transcatheter arterial embolization (TAE) with n-butyl cyanoacrylate (NBCA) in treating lower gastrointestinal bleeding caused by angiodysplasia. Methods. A retrospective study was performed to evaluate the clinical data of the patients with lower gastrointestinal bleeding caused by angiodysplasia. The patients were treated with superselective TAE with NBCA between September 2013 and March 2015. Angiography was performed after the embolization. The clinical signs including melena, anemia, and blood transfusion treatment were evaluated. The complications including abdominal pain and intestinal ischemia necrosis were recorded. The patients were followed up to evaluate the efficacy in the long run. Results. Seven cases (2 males, 5 females; age of 69.55 ± 2.25) were evaluated in the study. The embolization was successfully performed in all cases. About 0.2–0.8 mL (mean 0.48 ± 0.19 mL) NCBA was used. Immediate angiography after the embolization operation showed that the abnormal symptoms disappeared. The patients were followed up for a range of 2–19 months and six patients did not reoccur. No serious complications, such as femoral artery puncture point anomaly, vascular injury, and intestinal necrosis perforation were observed. Conclusion. For the patients with refractory and repeated lower gastrointestinal hemorrhage due to angiodysplasia, superselective TAE with NBCA seem to be a safe and effective alternative therapy when endoscopy examination and treatment do not work.

    A variety of approaches have been used to reduce Cardiovascular Disease (CVD) risk in the community, including programs based in the workplace. To date, it has been difficult to draw accurate conclusions on the effectiveness of worksite CVD risk reduction programs. Typically, such programs suffer from poor participation and high attrition rates and most lack physical and biochemical validation of self-reported lifestyle changes. The present paper describes an evaluation of four health promotion worksite interventions (screening, education, incentive and lifestyle change) conducted in the NSW Ambulance Service. The study achieved very high participation and low attrition rates. Self-reported changes in lifestyle were validated with physical and biochemical measures. The results suggest greater change in some risk factors for those individuals receiving the incentive and lifestyle change programs compared to screening alone or education. PMID:10109119

  9. Evaluation of interconnections between tanks and groundwater using stable isotope techniques - a case study from central Telangana state

    International Nuclear Information System (INIS)

    Identification of source and origin of groundwater and recharge chronology is of great importance for systematic planning for groundwater development and management, to sustain the current and future levels of the human development. Environmental tracers have been established as potential tools in tracing groundwater and its interconnections with other water bodies. Environmental isotopes are used as a modern, specific and reliable technique in understanding various hydrological processes. This study pertains to central region of Telangana, which falls under semi-arid region (∼ 900mm total rainfall) and most of the rainfall is mostly confined to a few intense rain events, storage and proper utilization of this vital source is very important. Tanks play a major useful role in confining the surface run-off and enhancing the groundwater recharge in shallow zones. This paper highlights the findings obtained from an isotope investigation to evaluate tank contribution to local groundwaters

    Full Text Available The construction of new rural communities is an important measure to promote the integration of urban and rural areas. The environmental quality of new rural communities represents the residential suitability of the communities. The evaluation of the environmental quality can help promote the healthy development of new rural communities. The present study combines AHP (Analytic Hierarchy Process and TOPSIS (Technique for Order Preference by Similarity to an Lead Solution for the evaluation and ordering of the environmental quality of 28 new rural communities in Henan Province, China. The AHP model containing four hierarchies is constructed: objective hierarchy, principle hierarchy, index hierarchy and factor hierarchy. The principle hierarchy is composed of 3 factors: social environment, material environment and ecological environment; the index hierarchy consists of 7 factors: service environment, civilized environment, planning environment, architectural environment, facility environment, greening environment, sanitation environment; the factor hierarchy consists of 14 factors: life service, health service, education degree, neighborhood relationship, spatial layout, functional layout, architectural style, architectural functions, infrastructure, public facilities, percentage of green open space, leisure and entertainment facilities, garbage treatment rate and wastewater treatment rate. By AHP model, the weight of the factors in every hierarchy is obtained and TOPSIS is employed for the ordering of the environmental quality of the 28 new rural communities. The results show: in the environmental evaluation, spatial layout, functional layout, architectural functions, infrastructure and neighborhood relationship have a relatively higher weight and more importance should be attached to these respects. The ordering of environmental quality of new rural communities has a high discrimination. The five communities with the highest environmental

    This report is the second of a series of studies to evaluate research and development (R&D) projects funded by the Automotive Lightweighting Materials (ALM) Program of the Office of Advanced Automotive Technologies (OAAT) of the U.S. Department of Energy (DOE). The objectives of the program evaluation are to assess short-run outputs and long-run outcomes that may be attributable to the ALM R&D projects. The ALM program focuses on the development and validation of advanced technologies that significantly reduce automotive vehicle body and chassis weight without compromising other attributes such as safety, performance, recyclability, and cost. Funded projects range from fundamental materials science research to applied research in production environments. Collaborators on these projects include national laboratories, universities, and private sector firms, such as leading automobile manufacturers and their suppliers. Three ALM R&D projects were chosen for this evaluation: Design and Product Optimization for Cast Light Metals, Durability of Lightweight Composite Structures, and Rapid Tooling for Functional Prototyping of Metal Mold Processes. These projects were chosen because they have already been completed. The first project resulted in development of a comprehensive cast light metal property database, an automotive application design guide, computerized predictive models, process monitoring sensors, and quality assurance methods. The second project, the durability of lightweight composite structures, produced durability-based design criteria documents, predictive models for creep deformation, and minimum test requirements and suggested test methods for establishing durability properties and characteristics of random glass-fiber composites for automotive structural composites. The durability project supported Focal Project II, a validation activity that demonstrates ALM program goals and reduces the lead time for bringing new technology into the marketplace. Focal

    The cultivation of GMPs in Europe raises many questions about the environmental risks, in particular about their ecological impact on non-target organisms and on soil properties. The aim of a multidisciplinary group engaged in a LIFE+project (MAN-GMP-ITA) was to validate and improve an existing environmental risk assessment (ERA) methodology on GMPs within the European legislative framework on GMOs. Given the impossibility of evaluating GMO impact directly, as GMPs are banned in Italy, GMPs have not been used at any stage of the project. The project thus specifically focused on the conditions for the implementation of ERA in different areas of Italy, with an emphasis on some sensitive and protected areas located in the North, Centre, and South of the country, in order to lay the necessary baseline for evaluating the possible effects of a GMP on soil communities. Our sub-group carried out soil analyses in order to obtain soil health and fertility indicators to be used as baselines in the ERA model. Using various methods of chemical, biochemical, functional and genetic analysis, our study assessed the changes in diversity and functionality of bacterial populations, and arbuscular mycorrhizal fungi. The results show that plant identity and growth, soil characteristics, and field site climatic parameters are key factors in contributing to variation in microbial community structure and diversity, thus validating our methodological approach. Our project has come to the conclusion that the uneven composition and biological-agronomical quality of soils need to be taken into consideration in a risk analysis within the framework of ERA for the release of genetically modified plants.

    The study evaluates the implementation of the Urban and Rural Planning Law in western China through questionnaires, interviews, onsite visits, and literature analysis. Results show that, though the western region has made great progress in the study and publicity of the Law, as well as in their local legislation and administrative system adjustments, there are problems impeding the implementation of the Law, such as overlapping government administration, inadequate implementation measures, controversial provisions that cause operational difficulties, local legislative confusion, and poor legal awareness. As such, this article proposes suggestions as follows: to legalize the detailed implementation rules and regulations, as well as other related regulations and technical standards, in order to improve the system of urban and rural planning laws and regulations; to strengthen legal supervision to maintain the authority of the law; to formulate proper planning policy guidelines based on the specifi c conditions of western region; and to strengthen the publicity, education, and training of the Law so as to promote the publics’ legal awareness.

    Full Text Available The nature of different activities in production, agriculture as well as distribution and consumption section, called as expansionist activities, largely influence the ability of the land. Production of consumable material, which is required for increasing population in various areas, and their attractions make it possible to earn more profit and it causes a significant pressure on soil and water resources and can threaten environmental pollution and human food security. A self-interested attitude on land resources has led to run short-term programs without considering the ecological capability of the land. These mentioned problems are, significantly intensified particularly in arid and semi-arid areas with severe limitations of water and soil quality and quantity. Therefore, land allocation based on ecological capability and self-purification indexes, used for land use planning, is an appropriate response to meet the deficiencies noted. This paper studies the agricultural capable lands based on land capability. The proposed study uses GIS software capabilities with application of the environmental ability evaluation model, as a holistic approach, to make sustainable development research in the region. The results indicate that suitable lands for agriculture in the whole area in different classes are widespread and with regards to dependency of more than 90 percent of people to agricultural activities, serious attention of authorities is required for providing the appropriate baseline and avoiding land use change to develop this activity.

    Full Text Available The geothermal potentiality in Egypt has a minor significance in the aspects of the Egyptians life, while the hydraulic and hydrocarbonresources are more convenient. However, some other applications for the geothermal activity such as direct warming, pools, and physiotherapy make the research for geothermal as requested. In the present work, two locations with rather good geothermal potentiality will be studied; these are HammamFaraun and Abu Swiera (water temperature is about 70 °C; at Sinai Peninsula.
    The contribution of the geophysical techniques to evaluate such potentiality could be considered, as its capability to identifythe reservoir characteristics and its implementation is acceptable. Therefore, a geophysical survey program has been conductedin terms of seventeen vertical electrical soundings (VES and two wide profiles of Control Source Electromagnetic (CSEM forward step at HammamFaraun and two wide profiles of CSEM at Abu Swiera. The geophysical techniques yield information on the spatial distribution of electrical conductivity, which is the most sensitive parameter to fluids in the rocks. 
    The analysis of the geophysical data, together with the field and geochemical studies lead to the conclusion that, the thermalwater in the subsurface formations might be considered as the preferred cause of the high conductivity in the subsurface on/close to the boarder of tectonically active regions, particularly, where the anomalous conductivity is correlated with high heat flow and other geophysical and geological parameters.

    International Nuclear Information System (INIS)

    The purpose of this study was to compare patients with multiple sclerosis and healthy control subjects as regards hemodynamics of cerebral venous drainage. Between December 2012 and May 2013, 44 consecutive patients with multiple sclerosis and 44 age- and sex-matched healthy subjects underwent the B-mode, color Doppler, and duplex Doppler evaluations of the internal jugular vein (IJV) and vertebral vein. The following four parameters were investigated: IJV stenosis, reversal of postural control of the cerebral venous outflow pathways, absence of detectable blood flow in the IJVs and/or vertebral veins, and reflux in the IJVs and/or vertebral veins in the sitting or supine position. In the study group, IJV stenosis, postural control reversal of the cerebral venous outflow pathways, and absence of flow in the IJVs and/or vertebral veins were found in 3 (6.8%), 2 (4.5%), and 3 (6.8%) patients, respectively. In the control group, IJV stenosis (P=0.12), postural control reversal of the cerebral venous outflow pathways (P=0.50), and absence of flow (P=0.12) were not detected. Abnormal reflux was found neither in multiple sclerosis patients nor in healthy subjects. No significant difference in the cerebral venous drainage through the IJV or vertebral vein was found between patients with multiple sclerosis and healthy subjects within any of the investigated ultrasonographic parameters

    Biogeomorphological understanding is becoming increasingly applied in a range of environmental management contexts. The concept of 'bioprotection' is of particular relevance in the built environment. Here, the influence of higher plants on the condition of buildings and building materials, particularly vulnerable historic structures, is of great interest for conservationists and managing authorities tasked with preserving built cultural heritage. Ivy (Hedera spp.) is a widespread and prolific creeping and climbing plant that is commonly found on built structures. Opinion varies as to whether ivy is good or bad for buildings, but there is evidence to suggest it can have both protective and deteriorative influences. Here we present a case study assessment of ivy removal from a brick and mortar wall (c.100 years old) in West Sussex, UK. Using measurements of hardness (Equotip L), moisture (protimeter %WME) and visual inspection we find that the condition of brickwork varied with ivy canopy cover extent, but that this effect was not consistent between different heights on the wall. The roles of ivy in moderating wall moisture dynamics is discussed as a possible contributing factor.

    Water resource is of great significance to the survival and development of human. However, the water resource system in karst regions is sensitive to external interference owing to the special geological processes which cause soil impoverishment, severe rocky desertification and large topographic height difference. Therefore, evaluating the sustainability of the water resource in karst regions is beneficial to reasonably use and protect water resource. This paper puts forward to evaluate the water resource from four aspects, including water resources system, water requirement system, ecosystem and social economic system. Moreover, on this basis, 18 evaluation indexes were selected to construct the sustainability evaluation index system and method. This method was used to evaluate the sustainability of the water resource in the typical karst region—Zunyi, Guizhou province, China, and was verified according to the actual situation in the research area. All these provide reference for the evaluation of the sustainability of the water resource in similar regions.

    2010-09-01

    Full Text Available Soil loss is commonly estimated using the Revised Universal Soil Loss Equation (RUSLE. Since RUSLE is an empirically based soil-loss model derived from surveys on plots, the high spatial and temporal variability of erosion in Mediterranean environments and scale effects mean that it is necessary to evaluate the model in other spatial units such as the microcatchment. In this study, a series of topographic and soil surveys was carried out on a microcatchment of 6.7 ha in a mountainous area under no-tillage farming with bare soil in order to examine spatial and temporal results produced by RUSLE. GPS measurements of the microrelief height differences were used in a control area in the microcatchment to compare observed erosion and deposition with RUSLE predictions. Erosion points located in certain areas correlate very closely with RUSLE predictions, while the distribution of deposition points showed no correlations with RUSLE predictions. Secondly, a time series of daily rainfall data was used to calculate annual erosivity values, which were fitted to an appropriate distribution function. It was determined that the rainfall distribution best fitted the Pearson type III distribution function. Next, efforts were made to quantify the long term erosion and to check the suitability of the land-use and management under different thresholds of tolerance. It was found that values of erosivity in the study area with a return period of 10 years generate a mean annual erosion of 5 t ha−1 yr−1. On the study scale, RUSLE allowed us to locate the most erosive areas and to combine the suitability of the soil land-use and the management with the frequency of the annual erosivity. In addition, an annual sediment delivery ratio of approximately 47% was estimated for the period 2005–2006.

    The Nubian Sandstone Aquifer (NSSA) is the main groundwater resource of the El-Bahariya Oasis, which is located in the middle of the Western Desert of Egypt. This aquifer is composed mainly of continental clastic sediments of sandstone with shale and clay intercalations of saturated thickness ranging between 100 and 1500 m. Vulnerability assessment to delineate areas that are more susceptible to contamination from anthropogenic sources has become an important element for sustainable resources management and land use planning. Accordingly, this research aims to estimate the vulnerability of NSSA by applying the DRASTIC model as well as utilising sensitivity analyses to evaluate the relative importance of the model parameters for aquifer vulnerability in the study area. The main objective is to demonstrate the combined use of the DRASTIC and the GIS techniques as an effective method for groundwater pollution risk assessment, and mapping the areas that are prone to deterioration of groundwater quality and quantity. Based on DRASTIC index (DI) values, a groundwater vulnerability map was produced usingthe GIS. The aquifer analysis in the study area highlighted the following key points: the northeastern and western parts of the NSSA were dominated by ‘High’ vulnerability classes while the northwestern and southeastern parts were characterised by ‘Medium’ vulnerability classes. The elevated central partof the study area displayed ‘Low’ aquifer vulnerability. The vulnerability map shows a relatively greater risk imposed on the northeastern part of the NSSA due to the larger pollution potential of intensive vegetable cultivation. Depth-to-water, topography and hydraulic conductivity parameters were found to be more effective in assessing aquifer vulnerability.

    Debris flows can be described as rapid mass movements, gravity induced able to transport large quantities of material downslope. This type of landslides is strongly controlled by the topography and usually occur in region characterized by steep slopes and at least seasonal heavy rainfall. One of the problem when dealing with debris flow susceptible areas is that the eroded surface is usually very shallow and it can be masked by the vegetation already few years after a landslide event. Therefore, debris flow prone areas very often suffer from lack of reliable landslide inventories necessary to calibrate and validate susceptibility models. In order to deal with this problem, transferability procedure (spatial partition) have already proved to be efficient in areas which show analogous topographic, lithological and climatic characteristics. A procedure to evaluate whether it is possible to apply model transferability is here proposed. This approach is based on the assumption that debris flow trigger in different locations under similar topographic conditions and includes: i) a test of similarity between training and test areas aimed at identifying thresholds in catchment similarity which allow to successfully perform the transferability; ii) the calibration of the susceptibility model in the training area; iii) the validation of the model on the test area. The debris flow susceptibility is here evaluated using a stochastic approach and the all procedure is implemented in a R script which can be easily used to test the procedure in other catchments. The study areas chosen to perform this study are located in the Messina province (southern Italy) respectively on the Ionian sector (Itala catchment) and on the Tyrrhenian sector (Saponara catchment). Itala catchment was hit by the sadly known debris flow event of the 1st October 2009 (37 fatalities and huge damages) while Saponara catchment on the 22nd November 2011 (only two years after the 2009 event) experienced a very

    Full Text Available Global data have been widely used for seismicity and seismic hazard assessment by seismologists. In the present study we evaluate worldwide seismicity in terms of maps of maximum observed magnitude (Mmax, seismic moment (M 0 and seismic moment rate (M 0S. The data set used consists of a complete and homogeneous global catalogue of shallow (h £ 60 km earthquakes of magnitude MS ³ 5.5 for the time period 1894-1992. In order to construct maps of seismicity and seismic hazard the parameters a and b derived from the magnitude-frequency relationship were estimated by both: a the least squares, and b the maximum likelihood, methods. The values of a and b were determined considering circles centered at each grid point 1° (of a mesh 1° ´1° and of varying radius, which starts from 30 km and moves with a step of 10 km. Only a and b values which fulfill some predefined conditions were considered in the further procedure for evaluating the seismic hazard maps. The obtained worldwide M max distribution in general delineates the contours of the plate boundaries. The highest values of M max observed are along the circum-Pacific belt and in the Himalayan area. The subduction plate boundaries are characterized by the largest amount of M 0 , while areas of continental collision are next. The highest values of seismic moment rate (per 1 year and per equal area of 10 000 km 2 are found in the Southern Himalayas. The western coasts of U.S.A., Northwestern Canada and Alaska, the Indian Ocean and the eastern rift of Africa are characterized by high values of M 0 , while most of the Pacific subduction zones have lower values of seismic moment rate. Finally we analyzed the seismic hazard in South America comparing the predicted by the NUVEL1 model convergence slip rate between Nazca and South America plates with the average slip rate due to earthquakes. This consideration allows for distinguishing between zones of high and low coupling along the studied convergence

    Full Text Available This paper reports on a study examining the usage, usability and impact of a charitable Website 'Drugscope'. A range of methods were used to evaluate the site, including Inspection, examining the extent to which the site met recognised quality criteria; formal usability tests, including information retrieval tasks; an online user survey and computer log analysis. Log results showed that the site attracted around 300-400,000 page views per month, although two-thirds of all users accessed just one page before going somewhere else. Although search engines tended to take most users to pages other than the 'Home' page, it is still likely that many users did not take full advantage of the information offered on the site. Survey respondents, mainly drug workers or academics, had a variety of information needs, that were generally well served by the site. Overall, the site is very well organised for retrieving information. In order to promote best practice, the research suggests that charities need to take account more the international audience attracted by the Web, include quality indicators such as source attribution and currency stamps, and make sites more accessible to those with disabilities. Overall, however, Drugscope proved itself to be a highly effective information provider.

  13. An integrated approach to dam safety evaluation. A case study: Upper Lake Falls Dam, Nova Scotia, Canada

    International Nuclear Information System (INIS)

    Upper Lake Falls Dam is located in southwestern Nova Scotia. It is the uppermost hydroelectric development in a series of six developments on the Mersey River. The total capacity of the Mersey River system is 42 MW. The reservoir of Upper Lake Falls, Lake Rossignol, is the largest in Nova Scotia with a total area of 66 square miles and a gross storage of 800,000 acre-feet. An overview is presented of the hydrologic and hydraulic investigations carried out for the dam, which is classified as having high hazard potential because of permanent village and urban developments located downstream. The general methodology adopted in the study consisted of the following: gathering and verifying all meteorologic and hydrologic data; evaluating the Probable Maximum Precipitation (PMP) assumed to occur over the basin, and of the antecedent conditions prior to the PMP; calibrating a watershed model on flood events generated by rainfall, and by a combination of snowmelt and rainfall, and verifying the model using additional hydrologic events; deriving the Probable Maximum Flood (PMF) using the PMP results simulated on the calibrated watershed model; hydrodynamic routing of the flood hydrograph through all the developments; dambreak analysis, following sequential or independent failures; and flood inundation mapping. Details are given of safety analysis of the earthfill and concrete dam structures, reservoir management and cost-benefit analyses. 7 refs., 8 figs., 1 tab

    Full Text Available Abstract Background Normalization is a prerequisite for accurate real time PCR (qPCR expression analysis and for the validation of microarray profiling data in microbial systems. The choice and use of reference genes that are stably expressed across samples, experimental conditions and designs is a key consideration for the accurate interpretation of gene expression data. Results Here, we evaluate a carefully selected set of reference genes derived from previous microarray-based transcriptional profiling experiments performed on Acidithiobacillus ferrooxidans and identify a set of genes with minimal variability under five different experimental conditions that are frequently used in Acidithiobacilli research. Suitability of these and other previously reported reference genes to monitor the expression of four selected target genes from A. ferrooxidans grown with different energy sources was investigated. Utilization of reference genes map, rpoC, alaS and era results in improved interpretation of gene expression profiles in A. ferrooxidans. Conclusion This investigation provides a validated set of reference genes for studying A. ferrooxidans gene expression under typical biological conditions and an initial point of departure for exploring new experimental setups in this microorganism and eventually in other closely related Acidithiobacilli. The information could also be of value for future transcriptomic experiments in other bacterial systems.

    2011-12-01

    The purpose of this study was three-fold: to measure the ability of the Medical Explorers case-based curriculum to improve higher order thinking skills; to evaluate the impact of the Medical Explorers case-based curriculum to help students be self directed learners; and to investigate the impact of the Medical Explorers case-based curriculum to improve student attitudes of the life sciences. The target population for this study was secondary students enrolled in advanced life science programs. The resulting sample (n = 71) consisted of 36 students in the case-based experimental group and 35 students in the control group. Furthermore, this study employed an experimental, pretest-posttest control group research design. The treatment consisted of two instructional strategies: case-based learning and teacher-guided learning. Analysis of covariance indicated no treatment effect on critical thinking ability or Motivation and Self-regulation of Learning. However, the Medical Explorers case-based curriculum did show a treatment effect on student attitudes toward the life sciences. These results seem to indicate that case-based curriculum has a positive impact on students' perspectives and attitudes about the study of life science as well as their interest in life science based careers. Such outcomes are also a good indicator that students enjoy and perceive the value to use of case studies in science, and because they see value in the work that they do they open up their minds to true learning and integration. Of additional interest was the observationthat on average eleventh graders showed consistently stronger gains in critical thinking, motivation and self-regulation of learning strategies, and attitudes toward the life sciences as compared to twelfth grade students. In fact, twelfth grade students showed a pre to post loss on the Watson-Glaser and the MSLQ scores while eleventh grade students showed positive gains on each of these instruments. This decline in twelfth

Two games have been build up for children aged between 7 and 13 years as a part of the European Researchers' Night activities (2011 and 2014-2015): a great board game with questions and drawings related to marine ecology and environmental protection and a memory game through which children can learn notions on Earthquakes, Volcanoes and Environment. Children's learning is facilitated if bound by game, and in this case images are more direct than words. 3. Surveys. A graphic questionnaire has been created in order to understand science perception and/or stereotypes in children who do not yet know how to read and write. In all these cases the relationship between researchers and artists has been extremely constructive and fruitful: researchers had to simplify their object of study in order to be able to disclose concepts that have been then translated into a simple and easy language.

  3. Fit-for-purpose: species distribution model performance depends on evaluation criteria - Dutch Hoverflies as a case study.

    Directory of Open Access Journals (Sweden)

    Jesús Aguirre-Gutiérrez

    Full Text Available Understanding species distributions and the factors limiting them is an important topic in ecology and conservation, including in nature reserve selection and predicting climate change impacts. While Species Distribution Models (SDM are the main tool used for these purposes, choosing the best SDM algorithm is not straightforward as these are plentiful and can be applied in many different ways. SDM are used mainly to gain insight in 1 overall species distributions, 2 their past-present-future probability of occurrence and/or 3 to understand their ecological niche limits (also referred to as ecological niche modelling. The fact that these three aims may require different models and outputs is, however, rarely considered and has not been evaluated consistently. Here we use data from a systematically sampled set of species occurrences to specifically test the performance of Species Distribution Models across several commonly used algorithms. Species range in distribution patterns from rare to common and from local to widespread. We compare overall model fit (representing species distribution, the accuracy of the predictions at multiple spatial scales, and the consistency in selection of environmental correlations all across multiple modelling runs. As expected, the choice of modelling algorithm determines model outcome. However, model quality depends not only on the algorithm, but also on the measure of model fit used and the scale at which it is used. Although model fit was higher for the consensus approach and Maxent, Maxent and GAM models were more consistent in estimating local occurrence, while RF and GBM showed higher consistency in environmental variables selection. Model outcomes diverged more for narrowly distributed species than for widespread species. We suggest that matching study aims with modelling approach is essential in Species Distribution Models, and provide suggestions how to do this for different modelling aims and species' data

    observed data to run the control simulations were supplied by ARPA-Piemonte. The study is focused on Maggiore Lake basin, an alpine basin between North-West of Italy and Southern Switzerland; results and statistical testing of the re-analyses shown in this presentation, are subdivided for each of three smaller sub-basins: Toce, Ticino and Maggia, in order to demonstrate the research progress on coupling meteorological and hydrological models in particular orographic features. It is presented how the meteorological forecasts are efficient into hydrological forecasting system, how the ensemble predictions are powerful to evaluate the uncertainty of the QPF which affects the QDF and the whole hydro-meteorological alert system for a mountain catchment. Further, in order to control the quality of the hydrological predictions in the short and medium term, statistical methods are used to calculate how the skill scores can be applied for hydrological applications and how the ensemble forecasts can help the users for decision making in management situations. Two significant events are analysed in order to compare the behaviour of the model driven by different weather scenarios: one convective in June that has yielded a high peak flow and one light stratiform in November that has been studied for the snow melt temperature which has affected the liquid precipitation and therefore the forecasted runoff. It is shown how the entire rainfall, the liquid precipitation and the runoff change in function of an areal the sub-basin scale, in order to understand where the errors are more frequently encountered.

    In recent years, significant advances have been made in business organization and management. The growing demands of clients as well as the globalization of world markets are among the many factors that have led to the establishment of systems of quality control and environmental management as a competitive strategy for businesses. When compared to other professional sectors, the construction sector has been slower to respond to environmental problems and to adopt Environmental Management Systems (EMS). In the world today the ISO 14001 standard is currently the main frame of reference used by construction companies to implement this type of management system. This article presents the results of a general study regarding the evaluation of the application of the ISO 14001 standard at civil engineering construction worksites in the Community of Madrid (Spain), specifically pertaining to requirement 4.4.1, Resources, roles, responsibilities, and authority. According to requirement 4.4.1, company executives should appoint people responsible for implementing the EMS and also specify their responsibilities and functions. The personnel designated for supervising environmental work should also have sufficient authority to establish and maintain the EMS. The results obtained were the following: - EMS supervisors did not generally possess adequate training and solid experience in construction work and in the environment. Furthermore, supervisors were usually forced to combine their environmental work with other tasks, which made their job even more difficult. - Generally speaking, supervisors were not given sufficient authority and autonomy because productivity at the construction site had priority over environmental management. This was due to the fact that the company management did not have a respectful attitude toward the environment, nor was the management actively involved in the establishment of the EMS. - Insufficient resources were allocated to the Environmental

    2015-02-01

    Strategic Environmental Assessment (SEA) is one of the key instruments for implementing sustainable development strategies in planning in general; in addition to being used in sectoral planning, it can also be used in other areas such as waste management planning. SEA in waste management planning has become a tool for considering the benefits and consequences of the proposed changes in space, also taking into account the capacity of space to sustain the implementation of the planned activities. In order to envisage both the positive and negative implications of a waste management plan for the elements of sustainable development, an adequate methodological approach to evaluating the potential impacts must be adopted and the evaluation results presented in a simple and clear way, so as to allow planners to make relevant decisions as a precondition for the sustainability of the activities planned in the waste management sector. This paper examines the multi-criteria evaluation method for carrying out an SEA for the Waste Management Plan for the city of Belgrade (BWMP). The method was applied to the evaluation of the impacts of the activities planned in the waste management sector on the basis of the environmental and socioeconomic indicators of sustainability, taking into consideration the intensity, spatial extent, probability and frequency of impact, by means of a specific planning approach and simple and clear presentation of the obtained results.

    2015-01-01

    Bone angiosarcomas, especially vertebral angiosarcomas, are very rare. There are no studies based on large clinical samples in the literature, and only a few single case reports can be found. The symptoms of the disease are not specific. It is usually detected incidentally or at a late stage when pathological vertebral fractures or neurological complications occur. Diagnostic imaging and history help to recognize the tumour behind the symptoms, but do not allow accurate clinical diagnosis. The basis for a diagnosis is the histopathological examination supported by immunohistochemistry (IHC) assays. The case of a 26-year-old woman with an angiosarcoma involving the eighth thoracic vertebra we report reflects diagnostic problems adversely affecting the efficacy and accuracy of treatment offered to patients. The patient underwent three surgeries of the spine, including two biopsies. A needle biopsy did not provide sufficient information for the diagnosis. An open excisional biopsy, which at the same time temporarily reduced neurological deficits in the patient, was the only chance to obtain an accurate diagnosis. The third surgery was posterior decompression of the spinal cord due to the rapidly escalating paraparesis. It was not until 8 weeks later that the final diagnosis was established. At that time, the patient could not be qualified for any supplementary treatment. The patient died in hospital 6 months after the onset of disease. PMID:26468177

    The results are described of an application of multiattribute analysis to the evaluation of high leverage prototyping technologies in the automation and robotics (A and R) areas that might contribute to the Space Station (SS) Freedom baseline design. An implication is that high leverage prototyping is beneficial to the SS Freedom Program as a means for transferring technology from the advanced development program to the baseline program. The process also highlights the tradeoffs to be made between subsidizing high value, low risk technology development versus high value, high risk technology developments. Twenty one A and R Technology tasks spanning a diverse array of technical concepts were evaluated using multiattribute decision analysis. Because of large uncertainties associated with characterizing the technologies, the methodology was modified to incorporate uncertainty. Eight attributes affected the rankings: initial cost, operation cost, crew productivity, safety, resource requirements, growth potential, and spinoff potential. The four attributes of initial cost, operations cost, crew productivity, and safety affected the rankings the most.

    Full Text Available This is a report of a case study on 234 patients with impetigo who referred to Razi Dermatology Hospital from April to November, 1989. Treatment was started immediately after obtaining direct smear and performing culture and antibiotic sensitivity test. The most common organism responsible for impetigo was the coagulase-positive staphylococcus (71%. In 13.7% of the cases, the coagulase-negative staphylococcus was grown on culture media, but none of the cultures showed streptococcus as the main organism. Treatment was started with oral penicillin V, oral erythromycin, benzathine penicillin G injection, oral cephalexin, and topical fuccidin. Clinical and bacteriological evaluation after 3-7 days showed that it is preferable to use oral cephalexin instead of other protocols such as oral erythromycin, which has previously been the drug of choice for impetigo. In addition, topical fuccidin with a 75% curative rate was the first drug for treatment, with the same effect as the oral cephalexin

    Health literacy comprises not only an individual's ability to gain access to, understand and use health information, but also health care providers' ability to make health information accessible and usable. The Fukushima nuclear accident has posed challenges related to the communication of radiation-related health information. Public health nurses are gatekeepers of community health in Japan, and have primary responsibility for communicating this complex information about science and risk to lay members of the community. A health literacy training program was designed to augment communication skills of participating nurses with two primary goals: changing communication practices and norms among public health nurses, and improving access to information for community residents. Training content incorporated an overview of health literacy skills (including numeracy), processes for assessing written materials and visual displays, as well as guidelines for text improvement. The workshop was spread across two days with two-hour sessions each day. A proximal post-training evaluation survey was conducted, followed by a more distal one-month follow-up evaluation to assess the application of learned skills in practice. Twenty-six nurses in Fukushima City attended the first trial. Post-training evaluations were highly positive, with agreement from 85-100% of participants on the appropriateness and usefulness of the workshop. During a one-month follow-up, the nurses reported applying new knowledge and skills to develop written materials. However, they faced difficulties sharing their new skills with colleagues and challenges changing work norms. Participants also encountered difficulties using graphics and explaining risks in practice. This paper highlights the importance of providing health literacy training opportunities for professionals to strengthen health system's ability to accessible information and services. This program also serves as important reference for future

  6. Building America Case Study: Evaluation of Passive Vents in New-Construction Multifamily Buildings, New York, New York

    2015-10-15

    Exhaust ventilation and corresponding outdoor air strategies are being implemented in high-performance new construction multifamily buildings to meet program or code requirements for improved indoor air quality, but a lack of clear design guidance is resulting in poor performance of these systems despite the best intentions of the programs or standards. CARB's 2014 'Evaluation of Ventilation Strategies in New Construction Multifamily Buildings' consistently demonstrated that commonly used outdoor air strategies are not performing as expected. Of the four strategies evaluated in 2014, the exhaust ventilation system that relied on outdoor air from a pressurized corridor was ruled out as a potential best practice due to its conflict with meeting requirements within most fire codes. Outdoor air that is ducted directly to the apartments was a strategy determined to have the highest likelihood of success, but with higher first costs and operating costs. Outdoor air through space conditioning systems was also determined to have good performance potential, with proper design and execution. The fourth strategy, passive systems, was identified as the least expensive option for providing outdoor air directly to apartments, with respect to both first costs and operating costs. However, little is known about how they actually perform in real-world conditions or how to implement them effectively. Based on the lack of data available on the performance of these low-cost systems and their frequent use in the high-performance building programs that require a provision for outdoor air, this research project sought to further evaluate the performance of passive vents.

    Aquifer storage, transfer and recovery (ASTR) may be an efficient low cost water supply technology for rural coastal communities that experience seasonal freshwater scarcity. The feasibility of ASTR as a water supply alternative is being evaluated in communities in south-western Bangladesh where the shallow aquifers are naturally brackish and severe seasonal freshwater scarcity is compounded by frequent extreme weather events. A numerical variable-density groundwater model, first evaluated against data from an existing community-scale ASTR system, was applied to identify the influence of hydrogeological as well as design and operational parameters on system performance. For community-scale systems, it is a delicate balance to achieve acceptable water quality at the extraction well whilst maintaining a high recovery efficiency (RE) as dispersive mixing can dominate relative to the small size of the injected freshwater plume. For the existing ASTR system configuration used in Bangladesh where the injection head is controlled and the extraction rate is set based on the community water demand, larger aquifer hydraulic conductivity, aquifer depth and injection head improve the water quality (lower total dissolved solids concentration) in the extracted water because of higher injection rates, but the RE is reduced. To support future ASTR system design in similar coastal settings, an improved system configuration was determined and relevant non-dimensional design criteria were identified. Analyses showed that four injection wells distributed around a central single extraction well leads to high RE provided the distance between the injection wells and extraction well is less than half the theoretical radius of the injected freshwater plume. The theoretical plume radius relative to the aquifer dispersivity is also an important design consideration to ensure adequate system performance. The results presented provide valuable insights into the feasibility and design

    Rehabilitation may be helpful in the prevention of complications associated with the treatment of patients with pectus excavatum who are subjected to surgery using the Ravitch and Nuss methods. This paper presents the case of a patient who underwent successful physical rehabilitation after 8 weeks from the surgery using the combined method. As part of the Nuss procedure, two plates were implanted to form a scaffolding for the patient's chest, which had previously been corrected with the Ravitch method. The plates were to be removed after 24 months of treatment. After the procedure, in spite of the favorable cosmetic effect of the repair, there was a significant decrease in the spirometric values and physical fitness of the patient. He underwent an individual physiotherapy program, which lasted four weeks. The streamlining of the respiratory system has significantly improved the spirometric values and raised the overall performance of the patient's organism. PMID:27212987

    The universalization of access of the electric energy is one of the goals established by the Brazilian government so as to attend the rural and urban population. The arrival of electric energy in remote and low income areas allows these populations to reach one of the basic conditions to improve the quality of life and citizenship. In order to achieve this goal efficiently, it is necessary to build tools that make possible the impact and process evaluation, searching the continuous improvement of the planning and decision making, either in the direction of the attendance of the proposed goals, or in the poverty mitigation. The knowledge originated from evaluation impact studies provides an important contribution to the improvement of social programs, and a return to society as how the public fund is being managed, promoting transparency and focus. In this context, tolls are developed so as to support the impact and process evaluation in terms of rural electrification publics policies, using a study case that includes about 23.000 questionnaires in 21 states, considering the moment before the access (ex-ante) and after (ex-post), during the years of 2000 and 2004.

    Proximate analysis components, gas content, porosity and permeability are the most important parameters for CBM reservoir evaluation. Based on the analysis of the conventional well log response of the no. 3 and no. 15 CBM seams in the southern Qinshui basin of China, regression analysis is used to establish the prediction models of the components of proximate analysis. The Langmuir rank equation is used to calculate the gas content. Variable matrix density is used to evaluate the total porosity. Based on the dual lateral log interaction method, a fracture porosity estimation model is established and the coal fracture permeability is predicted by using the Faivre-Sibbit method in the two CBM seams. Comparisons between the estimated and measured data of proximate analysis components, gas content, porosity and permeability indicate that the established models are credible. The absolute errors between the estimated moisture (Mad), ash (Aad), volatile (Vdaf), fixed carbon (FCad) and the measured results of coal in two coal seams are less than 0.41%, 9.47%, 3.61% and 9.41%, respectively. The absolute errors between the estimated and measured gas content are less than 4.05 cm3 g-1. The absolute errors of estimated total porosity and the analysed results of coal are less than 0.84%. Field samples show that Mad, Aad and Vdaf are less than 1.00%, 10.00%-25.00% and 10.00-15.00%, respectively, in the no. 3 and no. 15 CBM seams in the southern Qinshui basin. The FCad is close to 70.00%. The gas content ranges from 7.00 cm3 g-1 to 20.00 cm3 g-1 in the no. 3 coal seam and from 10.00 cm3 g-1 to 30.00 cm3 g-1 in the no. 15 coal seam. The total porosity is close to 5.50% and the fracture porosity is generally less than 2.50%. Fracture permeability is mainly distributed from 0.001 to 10 mD. The results indicate that the conventional well logs are effective in CBM reservoir evaluation.

    Presently, most of world electricity and other energy services are catered by fossil fuel resources. This is unsustainable in the long run both with respect to energy security and climate change problems. Fuel switching, specifically using biomass may partially address this problem. Polygeneration is an efficient way of delivering multiple utility outputs with one or more inputs. Decentralized small or large scale polygeneration using alternative fuels may be a future sustainable solution. In this paper, a techno-economic evaluation of a polygeneration with four utility outputs and rice straw as input has been reported. Results of the simulation and real-life data as inputs are used for the techno-economic analysis. The analysis is specific for a district in the state of West Bengal of India. Results show that such a plant has strong potential to qualify in techno-economic performance in addition to higher efficiency and lower CO2 emission. PMID:25647027

    MiKlip is project for medium-term climate prediction funded by the Federal Ministry of Education and Research in Germany (BMBF) and aims to create a model system that is able provide reliable decadal climate forecasts. During the first project phase of MiKlip the sub-project INTEGRATION located at Freie Universität Berlin developed a framework for scientific infrastructures (FREVA). More information about FREVA can be found in EGU2016-13060. An instance of this framework is used as Central Evaluation System (CES) during the MiKlip project. Throughout the first project phase various sub-projects developed over 25 analysis tools - so called plugins - for the CES. The main focus of these plugins is on the evaluation and verification of decadal climate prediction data, but most plugins are not limited to this scope. They target a wide range of scientific questions. Starting from preprocessing tools like the "LeadtimeSelector", which creates lead-time dependent time-series from decadal hindcast sets, over tracking tools like the "Zykpak" plugin, which can objectively locate and track mid-latitude cyclones, to plugins like "MurCSS" or "SPECS", which calculate deterministic and probabilistic skill metrics. We also integrated some analyses from Model Evaluation Tools (MET), which was developed at NCAR. We will show the theoretical background, technical implementation strategies, and some interesting results of the evaluation of the MiKlip Prototype decadal prediction system for a selected set of these tools.

  1. Goiania incident case study

    International Nuclear Information System (INIS)

    The reasons for wanting to document this case study and present the findings are simple. According to USDOE technical risk assessments (and our own initial work on the Hanford socioeconomic study), the likelihood of a major accident involving exposure to radioactive materials in the process of site characterization, construction, operation, and closure of a high-level waste repository is extremely remote. Most would agree, however, that there is a relatively high probability that a minor accident involving radiological contamination will occur sometime during the lifetime of the repository -- for example, during transport, at an MRS site or at the permanent site itself during repacking and deposition. Thus, one of the major concerns of the Yucca Mountain Socioeconomic Study is the potential impact of a relatively minor radiation-related accident. A large number of potential impact of a relatively minor radiation-related accident. A large number of potential accident scenarios have been under consideration (such as a transportation or other surface accident which results in a significant decline in tourism, the number of conventions, or the selection of Nevada as a retirement residence). The results of the work in Goiania make it clear, however, that such a significant shift in established social patterns and trends is not likely to occur as a direct outcome of a single nuclear-related accident (even, perhaps, a relatively major one), but rather, are likely to occur as a result of the enduring social interpretations of such an accident -- that is, as a result of the process of understanding, communicating, and socially sustaining a particular set of associations with respect to the initial incident

    In frequent case studies, the heterogeneity of vegetation formation is very high, because of the frequency of both natural and human disturbances. Consequently, the phytosociological approach .and the auto-ecological one are not completely adequate for the evaluation or the ecological state of this vegetation in a landscape.

    So, this evaluation needs the integration with a landscape ecological method of vegetation survey through schedules, as indicated by Ingegnoli (2002. Each type of schedule has been designed to check the organisation level and to estimate the metastability of a tessera of a certain type of vegetation, considering both general ecological and landscape ecological characters: (A Landscape e1ement characters (e.g. tessera, corridor, (8 Plant, biomass above ground, (C Ecocoenotope pararneters. (D Relation among the elements and their landscape parameters. There are four evaluation classes, the weights per class depending on an evaluation model designed as shown later on. The principal aim of this research is to design a new schedule, available for the main coenosis of salt marshes vegetation, which allows to complete a preliminary study on the Venice lagoon landscape dynamics, based on its vegetation. The landscape of the Venice lagoon is very complex and articulated, its main vegetation formations are the following: Underwater, Salt marshes. Littoral. Reclamation colonisations, Wet areas. Wooded patches and corridors. Agricultural cultivations, Urban green. The most important typc of vegetation is represented by salt marshes prairies called "barene", especially by Limonietum venetum (Pignani. 1966, This association can be divided into three sub-associations, the first with three facies: but the reality presents a large quantity of tesserae in intermediate or ecotonal states, even mixed with other associations (e,g, Spartinetum maritimae.

  4. FMCT verification: Case studies

    International Nuclear Information System (INIS)

    Full text: How to manage the trade-off between the need for transparency and the concern about the disclosure of sensitive information would be a key issue during the negotiations of FMCT verification provision. This paper will explore the general concerns on FMCT verification; and demonstrate what verification measures might be applied to those reprocessing and enrichment plants. A primary goal of an FMCT will be to have the five declared nuclear weapon states and the three that operate unsafeguarded nuclear facilities become parties. One focus in negotiating the FMCT will be verification. Appropriate verification measures should be applied in each case. Most importantly, FMCT verification would focus, in the first instance, on these states' fissile material production facilities. After the FMCT enters into force, all these facilities should be declared. Some would continue operating to produce civil nuclear power or to produce fissile material for non- explosive military uses. The verification measures necessary for these operating facilities would be essentially IAEA safeguards, as currently being applied to non-nuclear weapon states under the NPT. However, some production facilities would be declared and shut down. Thus, one important task of the FMCT verifications will be to confirm the status of these closed facilities. As case studies, this paper will focus on the verification of those shutdown facilities. The FMCT verification system for former military facilities would have to differ in some ways from traditional IAEA safeguards. For example, there could be concerns about the potential loss of sensitive information at these facilities or at collocated facilities. Eventually, some safeguards measures such as environmental sampling might be seen as too intrusive. Thus, effective but less intrusive verification measures may be needed. Some sensitive nuclear facilities would be subject for the first time to international inspections, which could raise concerns

    In this article I posit and examine certain criteria and qualities for ending an analysis. The case study describes the end phase of a four-year psychoanalysis in which the patient's decision to move to another area forced the end of his analysis. We continued to explore and work through his core neurotic conflicts that included issues of competitive rivalry, dominance and submission, control, and anxiety about birth and death. A shift in the transference from me as a negative father to me as a supportive but competitive older brother was also examined in the context of ending treatment as well as other aspects of the transference. In addition, we analyzed the meaning of his ending treatment based on an extra-analytic circumstance. In discussing this phase of treatment, the definition and history of the term "termination" and its connotations are reviewed. Various criteria for completing an analysis are examined, and technical observations about this phase of treatment are investigated. It was found that while a significant shift in the transference occurred in this phase of the patient's analysis, conflicts related to the transference were not "resolved" in the classical sense. Terminating treatment was considered as a practical matter in which the patient's autonomy and sense of choice were respected and analyzed. PMID:26583444

    Full Text Available This paper examines the economic effects of investment in developing and introducing Almond Late Flowering Cultivars (ALFC in a period of 52 years from 1968 to 2020, developed in Sahand Horticultural Research Station (SHRS, using the economic surplus model and field survey data. ALFC make almond supply curve move less to the left when there is a chilling case, thus affect the economic surplus of producers and consumers. Results showed that because of ALFC, economic surplus of producers and consumers had been increased about 0.4 and 0.6 million US Dollars, respectively that the share of consumers from benefits was 58 percent. The social net present value of ALFC regarding to the cost of research and extension was about 0.1 million US Dollars. It was identified that the internal rate of return in developing and introducing of ALFC had been about 11%. The findings expressed that if the research investment in ALFC could keep the position of almond supply curve unchanged unless the weather conditions, then the economic surplus of producers and consumers would decreased 3 and 4.2 million US Dollars less annually, respectively and internal rate of return in almond research would be 33 %. Comparing the results showed that the introduction of late flowering cultivars could reduce the loss only 4 % per hectare. The results illustrated that investment in R&E of almond could make supply curve shift less in chilling situation because of decrease in cultivation cost, but it is necessary to enhance almond yield too. The findings identify that the efficiency of current system of R&E for almond is low. So it is a necessity to find ways for make better the R&E performance in Iran.

    Full Text Available BACKGROUND: One Health addresses complex challenges to promote the health of all species and the environment by integrating relevant sciences at systems level. Its application to zoonotic diseases is recommended, but few coherent frameworks exist that combine approaches from multiple disciplines. Rabies requires an interdisciplinary approach for effective and efficient management. METHODOLOGY/PRINCIPAL FINDINGS: A framework is proposed to assess the value of rabies interventions holistically. The economic assessment compares additional monetary and non-monetary costs and benefits of an intervention taking into account epidemiological, animal welfare, societal impact and cost data. It is complemented by an ethical assessment. The framework is applied to Colombo City, Sri Lanka, where modified dog rabies intervention measures were implemented in 2007. The two options included for analysis were the control measures in place until 2006 ("baseline scenario" and the new comprehensive intervention measures ("intervention" for a four-year duration. Differences in control cost; monetary human health costs after exposure; Disability-Adjusted Life Years (DALYs lost due to human rabies deaths and the psychological burden following a bite; negative impact on animal welfare; epidemiological indicators; social acceptance of dogs; and ethical considerations were estimated using a mixed method approach including primary and secondary data. Over the four years analysed, the intervention cost US $1.03 million more than the baseline scenario in 2011 prices (adjusted for inflation and caused a reduction in dog rabies cases; 738 DALYs averted; an increase in acceptability among non-dog owners; a perception of positive changes in society including a decrease in the number of roaming dogs; and a net reduction in the impact on animal welfare from intermediate-high to low-intermediate. CONCLUSIONS: The findings illustrate the multiple outcomes relevant to stakeholders

    Directory of Open Access Journals (Sweden)

    Ana Cecilia Jara-Ettinger

    Full Text Available An estimated 800,000 people worldwide are occupationally exposed to welding-fumes. Previous studies show that the exposure to such fumes is associated with damage to genetic material and increased cancer risk. In this study, we evaluate the genotoxic effect of welding-fumes using the Micronucleus Test on oral mucosa cells of Mexican welders.We conducted a cross-sectional, matched case-control study of n = 66 (33 exposed welders, and 33 healthy controls. Buccal mucosa smears were collected and stained with acridine orange, observed under 100x optical amplification with a fluorescence lamp, and a single-blinded observer counted the number of micronuclei and other nuclear abnormalities per 2,000 observed cells. We compared the frequencies of micronuclei and other nuclear abnormalities, and fitted generalised linear models to investigate the interactions between nuclear abnormalities and the exposure to welding-fumes, while controlling for smoking and age.Binucleated cells and condensed-chromatin cells showed statistically significant differences between cases and controls. The frequency of micronuclei and the rest of nuclear abnormalities (lobed-nuclei, pyknosis, karyolysis, and karyorrhexis did not differ significantly between the groups. After adjusting for smoking, the regression results showed that the occurrence of binucleated cells could be predicted by the exposure to welding-fumes plus the presence of tobacco consumption; for the condensed-chromatin cells, our model showed that the exposure to welding-fumes is the only reliable predictor.Our findings suggest that Mexican welders who are occupationally exposed to welding-fumes have increased counts of binucleated and condensed-chromatin cells. Nevertheless, the frequencies of micronuclei and the rest of nuclear abnormalities did not differ between cases and controls. Further studies should shed more light on this subject.

    With the advances in electronics and information technology, China has gradually become the largest consumer of household appliances (HAs). Increasingly, end-of-life (EOL) HAs are generated in China. EOL recycling is a promising strategy to reduce dependence on virgin production, and indium is one of the recycled substances. The potential yield of indium recycling has not been systematically evaluated in China thus far. This paper estimates the potential yield of recycled indium from waste liquid crystal displays (LCDs) in China during the period from 2015 to 2030. The quantities of indium that will be used to produce LCDs are also predicted. The estimates focus on the following three key LCD waste sources: LCD TVs, desktop computers and portable computers. The results show that the demand for indium will be increasing in the near future. It is expected that 350 tonnes of indium will be needed to produce LCDs in China in 2035. The indium recycled from EOL LCDs, however, is much less than the demand and only accounts for approximately 48% of the indium demand. The sustainable index of indium is always less than 0.5. Therefore, future indium recycling efforts should focus on the development of recycling technology and the improvement of the relevant policy. PMID:26277718

  10. Characterization and evaluation of agro-ecosystems on a farm scale a study case: The Paysandu farming center (Medellin. Colombia)

    International Nuclear Information System (INIS)

    The state, condition, and tendencies of the agro-ecosystems (AE) of the Paysandu farming center of the Universidad Nacional de Colombia, sede Medellin were characterized and evaluated by means of parameterization and analysis of the various technological receptivity (RT, after the Spanish initials) and technological intensity (IT), based upon a methodological proposal of Velez and Gasto (1999), in terms of AE diversity and of the uses, management, and technological acceptance, techno-structural and hydro-structural endowment, potential productivity and services to the local, regional, and national society. The results showed that the greater part of the center (72%) has very low RT; which does not permit the establishment of mechanized advanced agro-technological management systems (SMA) however, 69.8% of the area is managed with SMA adequate for the restrictions imposed by the RT sixty-two percent of the area of the center, principally under pasture cover for dairy cattle production, is managed with advanced SMA. As a result of the interaction between RT and the SMA employed, six AE were identified, of which three, that represent 69.8% of the area (100.2 ha.), are managed with technologies adequate for their biophysical conditions or with technological receptivity (adequate IT), and the other three, that represent 28,57% of the are (43.1 ha.) ore managed with technologies that do not correspond to their RT conditions (tradition IT) which leads to a deterioration of their biophysical and ecological conditions

    Full Text Available On 4th of February, 2006 at about 10:00 pm.Chaq-Chaq dam failed due to overtopping. The fall of 131.2 mm of rain over a 24-hour period was recorded at Sulaimani metrological gage station, which is located about 7.5Kmsouth-east of the dam. As a result, the reservoir level rose, the dam has been overtopped and finally breached near the spillway at the right abutment. Fortunately no human lives loss nor important structure destruction were reporteddue to the dam failure. The aim of this paper is to estimate the flood hydrograph passing through Chaq-Chaq dam breach using measured breach geometry as input to unsteady option of HEC RAS 4.1.0 and calibrating the breach formation time to obtain the measured maximum water surface at Chaq-Chaq Bridge (1.36 km downstream of dam axis. In addition the recent breach prediction models were evaluated to check their accuracy in predicting the breach geometry, breach formation time and peak breach discharge.

    Conventional knowledge of the flood hazard alone (extent and frequency) is not sufficient for informed decision-making. The public safety community needs tools and guidance to adequately undertake flood hazard risk assessment in order to estimate respective damages and social and economic losses. While many complex computer models have been developed for flood risk assessment, they require highly trained personnel to prepare the necessary input (hazard, inventory of the built environment, and vulnerabilities) and analyze model outputs. As such, tools which utilize open-source software or are built within popular desktop software programs are appealing alternatives. The recently developed Rapid Risk Evaluation (ER2) application runs scenario based loss assessment analyses in a Microsoft Excel spreadsheet. User input is limited to a handful of intuitive drop-down menus utilized to describe the building type, age, occupancy and the expected water level. In anticipation of local depth damage curves and other needed vulnerability parameters, those from the U.S. FEMA's Hazus-Flood software have been imported and temporarily accessed in conjunction with user input to display exposure and estimated economic losses related to the structure and the content of the building. Building types and occupancies representative of those most exposed to flooding in Fredericton (New Brunswick) were introduced and test flood scenarios were run. The algorithm was successfully validated against results from the Hazus-Flood model for the same building types and flood depths.

    Full Text Available Fossil fuel shortage is a major challenge worldwide. Therefore, research is currently underway to investigate potential renewable energy sources. Biodiesel is one of the major renewable energy sources that can be obtained from oils and fats by transesterification. However, biodiesel obtained from vegetable oils as feedstock is expensive. Thus, an alternative and inexpensive feedstock such as waste cooking oil (WCO can be used as feedstock for biodiesel production. In this project, techno-economic analyses were performed on the biodiesel production in Hong Kong using WCO as a feedstock. Three different catalysts such as acid, base, and lipase were evaluated for the biodiesel production from WCO. These economic analyses were then compared to determine the most cost-effective method for the biodiesel production. The internal rate of return (IRR sensitivity analyses on the WCO price and biodiesel price variation are performed. Acid was found to be the most cost-effective catalyst for the biodiesel production; whereas, lipase was the most expensive catalyst for biodiesel production. In the IRR sensitivity analyses, the acid catalyst can also acquire acceptable IRR despite the variation of the WCO and biodiesel prices.

    Full Text Available Data Envelopment Analysis (DEA is a decision making tool based on linear programming for measuring the relative efficiency of a set of comparable units. DEA helps us identify the sources and level of inefficiency for each of the inputs and outputs. This approach has been used to evaluate the efficiency of the safety department in five construction companies. A three-input, safety workforce, safety training, and safety budget, and two-output, Perfect days and Uptime, constant returns-to-scale (CRS model was developed. The model indicated the necessary improvements required in the inefficient unit’s inputs and outputs to make it efficient, by identifying what factor is responsible for the low efficiency of performance, and also what factor should be improved in order to improve the efficiency of the safety department. The result shows that the safety department of firm A, B and D are efficient, but Firm C and Firm E can improve their efficiency by reducing inputs up to 3.34% and 6.05%, respectively. The inputs identified for reduction were; number of safety staffs and safety budget for Firm C and E respectively.

    Full Text Available Abstract Background The policy drive for the UK National Health Service (NHS has focused on the need for high quality services informed by evidence of best practice. The introduction of care pathways and protocols to standardise care and support implementation of evidence into practice has taken place across the NHS with limited evaluation of their impact. A multi-site case study evaluation was undertaken to assess the impact of use of care pathways and protocols on clinicians, service users and service delivery. One of the five sites was a midwifery-led Birth Centre, where an adapted version of the All Wales Clinical Pathway for Normal Birth had been implemented. Methods The overarching framework was realistic evaluation. A case study design enabled the capture of data on use of the pathway in the clinical setting, use of multiple methods of data collection and opportunity to study and understand the experiences of clinicians and service users whose care was informed by the pathway. Women attending the Birth Centre were recruited at their 36 week antenatal visit. Episodes of care during labour were observed, following which the woman and the midwife who cared for her were interviewed about use of the pathway. Interviews were also held with other key stakeholders from the study site. Qualitative data were content analysed. Results Observations were undertaken of four women during labour. Eighteen interviews were conducted with clinicians and women, including the women whose care was observed and the midwives who cared for them, senior midwifery managers and obstetricians. The implementation of the pathway resulted in a number of anticipated benefits, including increased midwifery confidence in skills to support normal birth and promotion of team working. There were also unintended consequences, including concerns about a lack of documentation of labour care and negative impact on working relationships with obstetric and other midwifery

    Reproductive failure in swine herds is often difficult to diagnose and is important to swine production. The present study aims to identify the potential risk factors (infectious/noninfectious) for stillborn piglets in two commercial swine farms situated in midwestern region of Brazil. The potential risk factors were included in a multivariable logistic model, and the dependent variable was defined as the presence of at least one stillborn piglet in a given litter (yes or no). In the best fit model, two variables from the multivariable analysis, total litter size (p = 0.01), and average birth weight (p = 0.03) were significantly associated with the presence of stillborn piglets at the farms examined in this study. Porcine circovirus type 2 (PCV2) was detected in 29.1 % of the litters. Neither parvovirus (PPV) nor leptospirosis infections were identified in this study, suggesting that they have a minor impact on reproductive disease. PMID:25516004

  17. Evaluating the direct and indirect rebound effects in household energy consumption behavior: A case study of Beijing

    International Nuclear Information System (INIS)

    This paper examines whether increases in energy efficiency of major household items cause additional short-run utilization of these end uses and other end uses for households in Beijing. An integrated model is first developed by combining a Logit model and a resource allocation model, where the former represents the choice of end-use ownership and the latter describes the end-use usage. The rebound effects are finally obtained from calculating the own- and cross-elasticities based on the prediction. The empirical results show that for refrigerators, electric fans, gas showers, TVs, and PCs, no evident rebound occurs; while for air conditioners, clothes washers, microwave ovens, and cars, either a direct rebound effect or an indirect rebound effect exists significantly. The respective average upper bound of direct rebound effects for them are 60.76%, 106.81%, 100.79%, and 33.61%, suggesting a possibility of backfire for the clothes washers and microwave ovens, while the respective upper bound of total rebound effects are 88.95%, 100.36%, 626.58%, and 31.61%. Furthermore, increasing the efficiency of air conditioners and cars can definitely reduce the total household energy consumption during the use phase. - Highlights: ► Evaluate the direct and indirect rebound effects for household energy consumption. ► Provide an evidence for rebound effect for the developing countries. ► Build an integrated model jointly representing end-use ownership and usage behavior. ► Significant rebound effects are found only for ACs, microwave ovens, washers and cars. ► Applicable policies for reducing residents' energy consumption in Beijing are given

  18. Evaluation of software and electronics technologies for the control of the E-ELT instruments: a case study

    International Nuclear Information System (INIS)

    In the scope of the evaluation of architecture and technologies for the control system of the E-ELT (European-Extremely Large Telescope) instruments, a collaboration has been set up between the Instrumentation and Control Group of the INAF-OATs and the ESO Directorate of Engineering. The first result of this collaboration is the design and implementation of a prototype of a small but representative control system for a kind of multi-object (optical) spectrograph. The electronics has been based on PLCs (Programmable Logical Controller) and Ethernet based field-buses from different vendors but using international standards like the IEC 61131-3 and PLCopen Motion Control. The baseline design for the control software follows the architecture of the VLT (Very Large Telescope) Instrumentation application framework but it has been implemented using the ACS (ALMA Common Software), an open source software framework developed for the ALMA project and based on CORBA middle-ware. The communication among the software components is based on two models: CORBA calls for command/reply using the client/server paradigm and CORBA notification channel for distributing the devices status using the publisher/subscriber paradigm. The communication with the PLCs is based on OPC UA, an international standard for the communication with industrial controllers. The results of this work will contribute to the definition of the architecture of the control system that will be provided to all consortia responsible for the actual implementation of the E-ELT instruments. This paper presents the prototype motivation, its architecture, design and implementation. (authors)

    Full Text Available In the context of the implementation of sustainable water treatment technologies for soil pollution prevention, a methodology that try to overcome the lack of runoff quality data in Puglia (Southern Italy is firstly tackled in this paper. It provides a tool to obtain total suspended solid (TSS pollutographs in areas without availability of monitoring campaigns. The proposed procedure is based on the relationship between rainfall characteristics and pollutant wash-off. In particular, starting from the evaluation of the observed regional rainfall patterns by using a rainfall generator model, the storm water management model (SWMM was applied on five case studies located in different climatic subareas. The quantity SWMM parameters were evaluated starting from the drainage network and catchments characteristics, while the quality parameters were obtained from results of a monitoring campaign conducted for quality model calibration and validation with reference to the pollutograph’s shape and the peak-time. The research yields a procedure useful to evaluate the first flush phenomenon in ungauged sites and, in particular, it provides interesting information for designing efficient and sustainable drainage systems for first flush treatment and diffuse pollution treatment.

    Solid dispersion (SD) technique is a promising strategy to improve the solubility and dissolution of BCS class II drugs. However, only few products are marketed till today based on SD technology due to poor flow properties and stability. The present work was intended to solve these problems by using combination approach, melt dispersion and surface adsorption technologies. The main aim of the present work is to improve the absorption in the stomach (at lower pH) where the absorption window exists for the drug by improving the dissolution, resulting in the enhancement of oral bioavailability of poorly soluble, weakly acidic drug with pH dependant solubility, i.e. valsartan. Melt dispersion granules were prepared in different ratios using different carriers (Gelucire 50/13, PEG 8000 and Pluronic F-68) and lactose as an adsorbent. Similarly, physical mixtures were also prepared at corresponding ratios. The prepared dispersion granules and physical mixtures were characterized by FTIR, DSC and in vitro dissolution studies. DSC studies revealed reduction in the crystallinity with a possibility of presence of amorphous character of drug in the dispersion granules. From dissolution studies, valsartan Gelucire dispersion (GSD4; 1:4 ratio) showed complete drug release in 30 min against the plain drug which showed only 11.31% of drug release in 30 min. Pharmacokinetic studies of optimized formulation in male Wistar rats showed 2.65-fold higher bioavailability and 1.47-fold higher Cmax compared to pure drug. The melt dispersion technology has the potential to improve dissolution and the bioavailability of BCS class II drugs. PMID:24796274

    Full Text Available Comparative genomics based on whole genome sequencing (WGS is increasingly being applied to investigate questions within evolutionary and molecular biology, as well as questions concerning public health (e.g., pathogen outbreaks. Given the impact that conclusions derived from such analyses may have, we have evaluated the robustness of clustering individuals based on WGS data to three key factors: (1 next-generation sequencing (NGS platform (HiSeq, MiSeq, IonTorrent, 454, and SOLiD, (2 algorithms used to construct a SNP (single nucleotide polymorphism matrix (reference-based and reference-free, and (3 phylogenetic inference method (FastTreeMP, GARLI, and RAxML. We carried out these analyses on 194 whole genome sequences representing 107 unique Salmonella enterica subsp. enterica ser. Montevideo strains. Reference-based approaches for identifying SNPs produced trees that were significantly more similar to one another than those produced under the reference-free approach. Topologies inferred using a core matrix (i.e., no missing data were significantly more discordant than those inferred using a non-core matrix that allows for some missing data. However, allowing for too much missing data likely results in a high false discovery rate of SNPs. When analyzing the same SNP matrix, we observed that the more thorough inference methods implemented in GARLI and RAxML produced more similar topologies than FastTreeMP. Our results also confirm that reproducibility varies among NGS platforms where the MiSeq had the lowest number of pairwise differences among replicate runs. Our investigation into the robustness of clustering patterns illustrates the importance of carefully considering how data from different platforms are combined and analyzed. We found clear differences in the topologies inferred, and certain methods performed significantly better than others for discriminating between the highly clonal organisms investigated here.

    We applied the seismic refraction method at archaeological site, Tepe Damghani located in Sabzevar, NE of Iran, in order to determine the structures of archaeological interests. This pre-historical site has special conditions with respect to geographical location and geomorphological setting, so it is an urban archaeological site, and in recent years it has been used as an agricultural field. In spring and summer of 2012, the third season of archaeological excavation was carried out. Test trenches of excavations in this site revealed that cultural layers were often disturbed adversely due to human activities such as farming and road construction in recent years. Conditions of archaeological cultural layers in southern and eastern parts of Tepe are slightly better, for instance, in test trench 3×3 m²1S03, third test trench excavated in the southern part of Tepe, an adobe in situ architectural structure was discovered that likely belongs to cultural features of a complex with 5 graves. After conclusion of the third season of archaeological excavation, all of the test trenches were filled with the same soil of excavated test trenches. Seismic refraction method was applied with12 channels of P geophones in three lines with a geophone interval of 0.5 meter and a 1.5 meter distance between profiles on test trench 1S03. The goal of this operation was evaluation of applicability of seismic method in identification of archaeological features, especially adobe wall structures. Processing of seismic data was done with the seismic software, SiesImager. Results were presented in the form of seismic section for every profile, so that identification of adobe wall structures was achieved hardly. This could be due to that adobe wall had been built with the same materials of the natural surrounding earth. Thus, there is a low contrast and it has an inappropriate effect on seismic processing and identifying of archaeological features. Hence the result could be that application of

    Full Text Available Decisions are a result of choices made between several alternatives and will affect all participants in the decision-making process. In this paper we analyze the Monte Carlo simulation as an important management tool in evaluating decisions under risk. The method is particularly useful in simulating decision problems. For example, the profit that could be achieved if a company launches a new product may depend on a number of factors (market share, advertising, production costs, launch costs, the lifetime of the product, etc. The company manager should identify all factors that could affect profit and then to consider the large number of ways in which these factors may interrelate. In such situations it is recommended company manager to divide the problem into smaller parts, asking him to estimate the probability distribution for market share, for advertising, for the cost of launch. Once they were obtained it can be determined their combined effect in order to obtain the probability distribution of profit. Through computer can generate a large number of possible combinations of situations where you choose a particular course of action. Upon completion of the simulation possible combination will be generated mostly while the least possible combination will be generated less frequently. For exemplification we selected a company producing shoes in Cluj market who wants to launch a new model for autumn-winter 2013-2014. In the current period the company has limited production capacity, has a number of additional contracts honored and general economic crisis situation makes money availability to be extremely limited. Accordingly, the company will have to choose a single product to be launched next season. The company will have to decide which of the two new products to be launched on the market: a model of boots for men in business class or a new model of women\\'s boots of the same class business. The company is not sure either production costs or

    Full Text Available The study discusses local farmers’ strategies of coping with and building resilience against the negative impact of climate change. Information for the discussion was from data collected using a set of structured questionnaires from interviews scheduled with 128 farmers. The questionnaire was based on previous literature and direct reconnaissance interview with farmers, which culminated in 13 strategies used for the study being reported. For each question, respondents were asked to choose their best and worst strategies. Thus, the difference between the best and worst strategies consistent with random utility theory has been used for the modelling. Results show that semi-transhumance, various handicrafts making, rural migration, small-scale vegetable production and small-scale river exploitation were the most important strategies identified, whilst water transport and vending, shifting cultivation, gypsum mining, gathering and trading of wild fruits and edible plants as well as cattle and sheep fattening were the least appreciated strategies identified amongst the farmers facing climate change. These findings are therefore imperative for planning farmers’ capacity-building and resilience against climate change projects to ensure sustainability in the study area.Keywords: Farmers’ adaptation strategies; Climate change resilience; Kaou

    Full Text Available Risk allocation is a key to managing risks associated with the public private partnership projects. Optimal risk allocation between the parties involved, namely public and private, is the essence of successful PPP project implementation. This study intends to identify and prioritize significant risk allocation criteria and barriers preventing the optimal allocation of risk to PPP projects in Malaysia. Due to interaction among criteria and barriers, this research has adopted analytic network process in order to decompose decision model into meaningful network and weight decision elements. Data has been collected through literature review, questionnaire and interview with PPP project experts. This study reveals that "Bear the risk at lowest price”, “Control the chance of risk" and "Risk attitude" are three major optimal risk allocation criteria. “Different sets of information about project risk”, "Lack of efficient risk allocation mechanisms" and “Lack of understanding the benefits of optimal allocation” are of three major optimal risk allocation barriers identified throughout the study. The outcome can be used to improve the implementation of PPP project in Malaysia by more rationally allocating risks between parties involved.

    A case-study regarding the results of the SENTIERI project on the Brescia-Caffaro NPCS (National Priority Contaminated Site) is reported. This area has been polluted mainly by polychlorinated biphenyls (PCBs), which have been classified recently by the International Agency for Research on Cancer as human carcinogens (group 1), with sufficient evidence for melanoma and limited for non-Hodgkin lymphoma (NHL) and breast cancer. The 3rd report of the SENTIERI project (2014) has shown an excess of cancer incidence with respect to the expected, on the basis of the incidence rates from the pool of Centre-North Italy cancer registries, but a mortality similar to that expected according to the regional rates, for melanoma, NHL and breast cancer. Furthermore, a higher than expected incidence has been found for various cancers which are not associated a priori with PCB exposure. The Brescia Local Health Authority has also carried out an analysis of cancer incidence, which has shown an incidence in the area similar to other ones in North Italy and a cluster of cases centered on Brescia town for melanoma only. A possible explanation of these discrepancies is the use of different reference populations for the comparisons (Region and pool of Centre-North Italy cancer registries), besides possible confounding bias. We discuss here the most critical aspects of modern ecological studies, their potential information content and interpretation limits. PMID:25759337

    Full Text Available Background & Aims of the Study: Promoting the health and safety is an important part of the fundamental mission of schools and one factor in designing and operating schools that always has been important is lighting. As students spend considerable hours in the classroom and school, lighting should be designed appropriately and in accordance with the standards, to protect them from injuries. Therefore, this study aimed to determine the combination of natural and artificial lighting condition in primary schools of Baneh city, Kurdistan, Iran. Materials & Methods: This is a cross-sectional study. It's population consisted of primary schools in the city of Baneh and 12 schools were randomly selected as samples. Measurement has been done, using observation method in those schools by completing the assessment form. Then collected data were analyzed by SPSS 19, using descriptive statistics, one-way ANOVA and Kruskal Wallis Test. Results: Results showed that the windows to the floor area in the most of schools classes were in standard range and just in 7 classes, the windows to the floor area ratio were less than standard. ANOVA showed the mean of luminance in those schools in p≤0.05 was significant and most of classes were in range of standard luminance. Comparison of luminance in schools corridors with standard showed that corridors luminance of 3schools were less than standard range. Conclusions: The amount of luminance in all schools was not appropriate especially in old schools. Therefore, to reduce the effect of inappropriate lightning on health in some classes, it is necessary to redesign the system. Furthermore, for parsimony, the lightning system modification is required to achieve standard luminance which is important.

    Construction and demolition (C&D) waste dumped alongside roads and in open areas is a major source of soil and underground water pollution. Since 2006, Israeli ministry for environmental protection enacted a policy of vehicle impoundment (VI) according to which track drivers caught while dumping C&D waste illegally have their vehicles impounded. The present study attempted to determine whether the VI policy was effective in increasing the waste hauling to authorized landfill sites, thus limiting the number of illegal unloads of C&D waste at unauthorized landfill sites and in open areas. During the study, changes in the ratio between the monthly amount of C&D waste brought to authorized landfills sites and the estimated total amount of C&D waste generated in different administrative districts of Israel were examined, before and after the enactment of the 2006 VI policy. Short questionnaires were also distributed among local track drivers in order to determine the degree of awareness about the policy in question and estimate its deterrence effects. According to the study's results, in the district of Haifa, in which the VI policy was stringently enacted, the ratio between C&D waste, dumped in authorized landfill sites, and the total amount of generated C&D waste, increased, on the average, from 20% in January 2004 to 35% in October 2009, with the effect attributed to the number of vehicle impoundments being highly statistically significant (t=2.324; p0.1). The analysis of the questionnaires, distributed among the local truck drivers further indicated that the changes observed in the district of Haifa are not coincident and appeared to be linked to the VI policy's enactment. In particular, 62% of the truck drivers, participated in the survey, were aware of the policy and 47% of them personally knew a driver whose vehicle was impounded. Furthermore, the drivers estimated the relative risk of being caught for unloading C&D waste in unauthorized sites, on the average, as

    Full Text Available Abstract Background In-hospital case-fatality rates in patients, admitted for acute myocardial infarction (AMI-CFRs, are internationally used as a quality indicator. Attempting to encourage the hospitals to assume responsibility, the Belgian Ministry of Health decided to stimulate initiatives of quality improvement by means of a limited set of indicators, among which AMI-CFR, to be routinely analyzed. In this study we aimed, by determining the existence of inter-hospital differences in AMI-CFR, (1 to evaluate to which extent Belgian discharge records allow the assessment of quality of care in the field of AMI, and (2 to identify starting points for quality improvement. Methods Hospital discharge records from all the Belgian short-term general hospitals in the period 2002-2005. The study population (N = 46,287 included patients aged 18 years and older, hospitalized for AMI. No unique patient identifier being present, we tried to track transferred patients. We assessed data quality through a comparison of MCD with data from two registers for acute coronary events and through transfer and sensitivity analyses. We compared AMI-CFRs across hospitals, using multivariable logistic regression models. In the main model hospitals, Charlson's co-morbidity index, age, gender and shock constituted the covariates. We carried out two types of analyses: a first one wherein transferred-out cases were excluded, to avoid double counting of patients when computing rates, and a second one with exclusion of all transferred cases, to allow the study of patients admitted into, treated in and discharged from the same hospital. Results We identified problems regarding both the CFR's numerator and denominator. Sensitivity analyses revealed differential coding and/or case management practices. In the model with exclusion of transfer-out cases, the main determinants of AMI-CFR were cardiogenic shock (ORadj 23.0; 95% CI [20.9;25.2], and five-year age groups ORadj 1.23; 95

    2016-06-01

    Full Text Available Most of the geochemical datasets include missing data with different portions and this may cause a significant problem in geostatistical modeling or multivariate analysis of the data. Therefore, it is common to impute the missing data in most of geochemical studies. In this study, three approaches called half detection (HD, multiple imputation (MI, and the cosimulation based on Markov model 2 (MM2 are used to impute the censored data. According to the fact that the new datasets have to satisfy the original data underlying structure, the Multidimensional Scaling (MDS approach has been used to explore the validity of different imputation methods. Log-ratio transformation (alr transformation was performed to open the closed compositional data prior to applying the MDS method. Experiments showed that, based on the MDS approach, the MI and the MM2 could not satisfy the original underlying structure of the dataset as well as the HD approach. This is because these two mentioned approaches have produced values higher than the detection limit of the variables.

    Separate collection of municipal solid waste has overcome the 50% threshold in the Asti District in northern Italy, nearly one-third being composed of household and green organic waste. In order to address present and future solutions, it becomes therefore fundamental to assess the environmental performances of the current management of organic waste from separate collection. A from-gate-to-cradle life cycle assessment (LCA) model has been developed by expanding system boundaries, in order to carry out the assessment in the context of the whole waste management streamline. The environmental performances of an existing aerobic plant were made available, based on field measured data, by paying attention to the role and contribution of waste management subsystems. The need for actual and reliable data on materials and energy input, as well as gross and net gains from materials recovery, including benefits arising from use of compost in farming activities, was probably the major drawback that had to be faced. The study integrated the findings of different investigations from the literature with field measured data in order to obtain a more comprehensive framework representative of the area under study. The results may help public administrators to better understand the suitability of using LCA tools when dealing with solid waste management strategies. (author)
