  3. Comparative economic analysis: Anaerobic digester case study

    International Nuclear Information System (INIS)

    An economic guide is developed to assess the value of anaerobic digesters used on dairy farms. Two varieties of anaerobic digesters, a conventional mixed-tank mesophilic and an innovative earthen psychrophilic, are comparatively evaluated using a cost-effectiveness index. The two case study examples are also evaluated using three other investment merit statistics: simple payback period, net present value, and internal rate of return. Life-cycle savings are estimated for both varieties, with sensitivities considered for investment risk. The conclusion is that an earthen psychrophilic digester can have a significant economic advantage over a mixed-tank mesophilic digester because of lower capital cost and reduced operation and maintenance expenses. Because of this economic advantage, additional projects are being conducted in North Carolina to increase the rate of biogas utilization. The initial step includes using biogas for milk cooling at the dairy farm where the existing psychrophilic digester is located. Further, a new project is being initiated for electricity production with thermal reclaim at a swine operation

    Full Text Available :The majority of the industrial machine components have to satisfy to the requirements of the high quality and incessantly increasing; so the machines maintaining in good state during the production has became a fundamental point for a product or a company success. Through the measure of the predictive maintenance, it is possible to satisfy these complex requirements with success and to reduce the costs of maintenance. However, an optimization of the maintenance is realized by a continued monitoring of degradation, by way of a control system on line “On Line”, which can respond to industrial imperatives and which provides to define just the necessary at the level of interventions, “The machine can’t be serviced except if only its state requires.”For an effective maintenance, it takes precise and reliable measures. Nevertheless, the experience has shown that the vibratory measure is the most reliable parameter that gives the precociously and with a best ways the deterioration state of a turnable machine. It provides to identify the efforts as soon as they appear, before of an irreversible damage, it also provides, after analysis, to deduce the origin and to estimate the breakdown risks.In this context, a study had done inside a workshop of a phosphoric office, which adopt a continued surveillance (On-Line, in the hope of doing an optimal process of a conditional maintenance which can be developed in time toward an idealized by a vibratory indicator accomplishing satisfactory results.

    Full Text Available Earthquake occurred in multistoried building shows that if the structures are not well designed and constructed with and adequate strength it leads to the complete collapse of the structures. To ensure safety against seismic forces of multi-storied building hence, there is need to study of seismic analysis to design earthquake resistance structures. In seismic analysis the response reduction was considered for two cases both Ordinary moment resisting frame and Special moment resisting frame. The main objective this paper is to study the seismic analysis of structure for static and dynamic analysis in ordinary moment resisting frame and special moment resisting frame. Equivalent static analysis and response spectrum analysis are the methods used in structural seismic analysis. We considered the residential building of G+ 15 storied structure for the seismic analysis and it is located in zone II. The total structure was analyzed by computer with using STAAD.PRO software. We observed the response reduction of cases ordinary moment resisting frame and special moment resisting frame values with deflection diagrams in static and dynamic analysis. The special moment of resisting frame structured is good in resisting the seismic loads.

    This article will explore pediatric consent through the analysis of a clinical case study using the principles of biomedical ethics approach. Application of the principles of autonomy, nonmaleficence, beneficence, and justice will be dissected in order to attempt to establish resolution of the ethical dilemma. The main conflict in this case study deals with whether the wishes of an adolescent for end-of-life care should be followed or should the desire of his parents outweigh this request. In terminal cancer, the hope of early palliative care and dignity in dying serve as priorities in therapy. Application of the moral principles to both sides of the dilemma aided in providing an objective resolution to uphold pediatric consent. PMID:22753459

    Building energy audit examines the ways actual energy consumption is currently used in the facility, in the case of a completed and occupied building and identifies some alternatives to reduce current energy usage. Implementation of energy audit are practically used to analyze energy consumption pattern, monitoring on how the energy used varies with time in the building, how the system element interrelate, and study the effect of external environment towards building. In this case study, a preliminary energy audit is focusing on Air-Conditioning & Mechanical Ventilation (ACMV) system which reportedly consumed 40% of the total energy consumption in typical building. It is also the main system that provides comfortable and healthy environment for the occupants. The main purpose of this study is to evaluate the current ACMV system performance, energy optimization and identifying the energy waste on UTeM's academic building. To attain this, the preliminary data is collected and then analyzed. Based on the data, economic analysis will be determined before cost-saving methods are being proposed.

  15. Sensitivity Analysis Case Study: Incorporating Organisational Factors in HRA

    International Nuclear Information System (INIS)

    represent the influence of these factors as either aspects of context, common performance conditions, or violation producing conditions. Additionally, consideration of structures for analysis of culture (ASCOT) and organisational factors (SOCRATES) made identification of important factors easier. Sensitivity findings. It is possible to account for the influence of organisational factors quantitatively in HRA by employing existing/emerging HRA methods. The human error probability estimate for overmatching leading to criticality obtained from the retrospective analysis performed in this limited study was a factor of 26 times higher than the case where only conditional HEP values without a consideration of organisational factors were employed. When PSFs including underlying organisational factors are accounted for the chance for the criticality event increased from 5 in one thousand to 1 out of 10. Recovery from either selection of an unsafe geometry vessel or from double batching was also sensitive to the effects of organisational factors in combination with other PSFs. For example, in the case of batching with supervisor recovery the CHEP is computed as (.01 x .24 = .0024) with OF considered the CHEP x OF = (.05 x 1 = .05). In this case the HEP has increased by a factor of 20. (authors)

    Interest in energy storage has continued to increase as states like California have introduced mandates and subsidies to spur adoption. This energy storage includes customer sited behind-the-meter storage coupled with photovoltaics (PV). This paper presents case study results from California and Tennessee, which were performed to assess the economic benefit of customer-installed systems. Different dispatch strategies, including manual scheduling and automated peak-shaving were explored to determine ideal ways to use the storage system to increase the system value and mitigate demand charges. Incentives, complex electric tariffs, and site specific load and PV data were used to perform detailed analysis. The analysis was performed using the free, publically available System Advisor Model (SAM) tool. We find that installation of photovoltaics with a lithium-ion battery system priced at $300/kWh in Los Angeles under a high demand charge utility rate structure and dispatched using perfect day-ahead forecasting yields a positive net-present value, while all other scenarios cost the customer more than the savings accrued.

  19. Corporate investment decisions and economic analysis. Exercises and case studies

    International Nuclear Information System (INIS)

    Economic analysis of industrial projects is based on methods which are often simple, sometimes complex, yet always to be applied with rigor. The aim of this book is to help readers assimilate the concepts and methods for investment decision and project evaluation. It offers a wide range of exercises, problems and case studies taken from business, which are the fruit of many years of teaching, consulting and research. Some are direct application of basics, others require a higher degree of reflection for more complex applications. Our approach borrows elements from micro economics, engineering economics and finance theory. While many examples relate to the energy sector, particularly oil and gas, the problems addressed are of broader scope and so are fully applicable to other industry sectors. This book is ideally suited to both professionals and students who seek to master capital budgeting techniques. A review of essential points is proposed at the beginning of each chapter and key methodological elements are recalled in the solutions. (authors)

  1. Case study: EM survey's application in fracture trace analysis

    International Nuclear Information System (INIS)

    Photo fracture trace analyses have been applied extensively in remedial investigations to determine the preferential pathways of groundwater and contaminants in the crystalline rock area. However, it is difficult to pinpoint a photo fracture trace in the field when the fracture is composed of several smaller individual fractures or is only several feet wide. In this respect, electromagnetic (EM) surveys provide an efficient method to complement the photo fracture trace analyses. This paper presents two case studies where EM surveys were applied to determine the occurrence of fractures and the survey results were used to locate monitoring and recovery wells. Case Study 1 involves a CERCLA site contaminated with volatile organic compounds and heavy metals. Case study1 is a CERCLA site at Baltimore County, Maryland. Case study 2 is a petroleum contamination site at Martinsburg, West Virginia. EM surveys at the two sites revealed that the main photo fracture traces are composed of several smaller individual fractures parallel to each other. The wells installed on the EM fractures yielded a lot more water than the wells installed based on the photo fracture trace analyses. Additionally, the thickness of the residual soil and the locations of cavities were well predicted by the EM data

Leukemia has the highest incidence, followed by tumors of the central nervous system (CNS and lymphomas (Hodgkin lymphoma, HL, and Non-Hodgkin's lymphoma, NHL. Spatial distribution of childhood cancer cases has been under concern with the aim of identifying potential risk factors.The two objectives are to study overall spatial clustering and cluster detection of cases of the three main childhood cancer causes, looking to increase etiological knowledge.We ran a case-control study. The cases were children aged 0 to 14 diagnosed with leukemia, lymphomas (HL and NHL or CNS neoplasm in five Spanish regions for the period 1996-2011. As a control group, we used a sample from the Birth Registry matching every case by year of birth, autonomous region of residence and sex with six controls. We geocoded and validated the address of the cases and controls. For our two objectives we used two different methodologies. For the first, for overall spatial clustering detection, we used the differences of K functions from the spatial point patterns perspective proposed by Diggle and Chetwynd and the second, for cluster detection, we used the spatial scan statistic proposed by Kulldorff with a level for statistical significance of 0.05.We had 1062 cases of leukemia, 714 cases of CNS, 92 of HL and 246 of NHL. Accordingly we had 6 times the number of controls, 6372 controls for leukemia, 4284 controls for CNS, 552 controls for HL and 1476 controls for NHL. We found variations in the estimated empirical D(s for the different regions and cancers, including some overall spatial clustering for specific regions and distances. We did not find statistically significant clusters.The variations in the estimated empirical D(s for the different regions and cancers could be partially explained by the differences in the spatial distribution of the population; however, according to the

    Full Text Available Business schools are exploring new pedagogical approaches to learning in order to deal with challenges such as increased class sizes, limited funding support, and difficulties in facilitating and encouraging active participation and learning among a diverse cohort of students. This paper reports on a study of the effectiveness of a pedagogical approach that blends online discussion board and case study. Analysing quantity and quality of online postings and comparing accounting students’ performance with previous cohort, this study observes a significant improvement in student learning. Appropriate design and delivery strategies and clear assessment criteria for assessment and use have provided an effective learning vehicle for students, helped them overcome their own language related barriers, and encouraged them to participate in a nonthreatening environment. This approach further complemented the benefits of peer-to-peer learning and case study pedagogy. Reported increase in workload for students and marking load for academics and measuring the value of learning, however, are some of the challenges that need further attention by researchers.

    Medicine counterfeiting is a current problem that the whole pharmaceutical field has to deal with. In 2014, counterfeits entered the legitimate supply chain in Europe. Quick and efficient action had to be taken. The aim of this paper is to explain which analytical strategy was chosen to deal with six of the cases concerned and which criteria have to be considered to provide quick and thorough information about the counterfeits. The evaluation of the packaging was performed in a first step, based on a comparison with genuine samples and evaluation of manipulation signs. Chemical methods were then used, consisting of near infrared and infrared spectroscopy, capillary zone electrophoresis and ultraviolet-visible spectrophotometry, in order to authenticate the samples and provide the chemical composition of the confirmed counterfeits. Among the 20 samples analyzed, 17 were confirmed as counterfeits. The counterfeits were the results of the manipulation of genuine samples, and one contained totally counterfeited parts. Several manipulation signs were asserted, like the addition of glue on the boxes and the vials. Genuine stolen goods had been diluted with water, while for an isolated case, a different active ingredient had been introduced in a vial. The analytical data generated were further investigated from a forensic intelligence perspective. Links could be revealed between the analyzed counterfeits, together with some interesting information about the modus operandi of the counterfeiters. The study was performed on a limited number of cases, and therefore encourages chemical and packaging profiling of counterfeits at a bigger scale. Copyright © 2015 John Wiley & Sons, Ltd.

    Full Text Available The following paper is concerned with elucidating an account of forms of new localism as they relate to the concept of ‘habitele’, a conceptual framework that helps us understand new forms of relatedness in the digitally mediated world. In doing this it will also reflect back on the concept and draw out as yet unconsidered elements based upon issues of fluidity, mobility, and what we will call ‘distal-locals’. The paper is centred around two case studies: the first is of a smart phone app, vouchercloud and details the way that the offering of money-off vouchers rests on particular notions of the local; while the second is of a environment organization who uses information technology to promote their activities. It is premised upon a history of work in the sociology of science and technology studies (STS and in particular a set of conceptual and methodologicalresources that helps to reveal the complexities of notions such as “the local”.

    Full Text Available Forest fires in Italy are mainly caused by humans, and directly depend on social behavior, whether voluntary (arson or involuntary (negligence. Despite the progress in knowledge made with studying the physical facets of the phenomenon, causes and motives of human-related fire remain mostly unknown. This paper proposes the implementation of the Delphi method (an interactive expert-questionnaire process in order to assess why fires are ignited. In four study cases, within a high fire incidence area (southern Italy, the Delphi technique identified as major cause of negligence the use of fire in agriculture and, as major causes of voluntary fires, motives related to seasonal labor. The main results in terms of frequency are: (i for involuntary events (negligence, experts unanimously identified the relevant importance of negligent use of agricultural fires, particularly stubble burning (13.99% of responses. For (ii voluntary fires (arson, results highlight the relative importance of fires ignited by seasonal workers as an instrument to force or maintain employment (8.41% of responses.

    Agriculture activities can play a double role in emitting or sequestering carbon from the atmosphere. Mitigation of greenhouse gas (GHG) emissions in agriculture is one of the most urgent research subjects in the framework of enhancing environmental stewardship. However, little is known about the role of the agriculture in the global carbon balance, since most of the studies applied the Eddy Covariance technique in natural or semi-natural ecosystems to investigate their role in mitigate the anthropogenic carbon release. The application of the Eddy Covariance technique in agricultural systems could greatly improve our knowledge about their role on the global carbon budget and help in modeling the related processes. In addition, there is a growing request from producers, trade companies, and customers on the assessment of the environmental impact of a production process related to agricultural high quality products. In recent years, particular attention was put on the estimation of GHG emissions deriving from productive processes. In this context, a useful tool is the Life Cycle Assessment (LCA), which represents a methodology to estimate GHG emissions related to the entire life cycle of a product. The Carbon Footprint (CF) analysis represents a subset of the LCA, which only considers CO2 emissions with an impact on climate change. With respect to the wine industry, most of studies focused on the CF analysis related to the wine making process in the cellar, while a few studies analyzed the GHG emissions related to the grape production. The aim of this work was to quantify the CO2 emissions due to the grape production and emphasize the double role of a vineyard as a carbon sink or source. An Eddy Covariance station was set up in a representative vineyard located in the Mediterranean Basin (Sardinia, Italy) to measure the net carbon exchange between the surface and the atmosphere. The CF analysis was also conducted to compute the carbon balance of the grape production

  16. Regulatory performance analysis case study: Britain's electricity industry

    International Nuclear Information System (INIS)

    The success or failure of the privatisation and liberalisation of electricity supply industries has more often been judged in terms of process than of outcomes. In this paper, in contrast, this performance is assessed in terms of the performance of its associated system of regulatory governance. Taking the UK's electricity supply industry between 1989 and 2000 as case study, initially, a vertical cross-section of the regulation system gives a finding matrix for the various stakeholders involved and identifying winners and losers from the standpoint of funding flows. Next, a horizontal cross-section provides the environmental, distributive, allocative, dynamic and productive efficiencies grid for this system. The survey shows that the performance of the British ESI regulation system produced benefits, although not for all stakeholders and not as fairly as possible. The chosen path did not seem sustainable and failed to respect intergenerational transfers as a way of fostering sustainability and equity. It was unable to underpin simultaneous improvements in efficiencies over time, while redistributing industry's funding flows among the players in a regressive manner

  19. Multivariate analysis in provenance studies: Cerrillos obsidians case, Peru

    International Nuclear Information System (INIS)

    We present the preliminary results of a provenance study of obsidians samples from Cerrillos (ca. 800-100 b.c.) using Moessbauer Spectroscopy. The Cerrillos archaeological site, located in the Upper Ica Valley, Peru, is the only Paracas ceremonial center excavated so far. The archaeological data collected suggest the existence of a complex social and economic organization on the south coast of Peru. Provenance research of obsidian provides valuable information about the selection of lithic resources by our ancestors and eventually about the existence of communication routes and exchange networks. We characterized 18 obsidian artifacts samples by Moessbauer spectroscopy from Cerrillos. The spectra, recorded at room temperature using different velocities, are mainly composed of broad asymmetric doublets due to the superposition of at least two quadrupole doublets corresponding to Fe2+ in two different sites (species A and B), one weak Fe3+ doublet (specie C) and magnetic components associated to the presence of small particles of magnetite. Multivariate statistical analysis of the Moessbauer data (hyperfine parameters) allows to defined two main groups of obsidians, reflecting different geographical origins.

    2010-08-01

    This paper is an introduction into the analysis of multispectral recordings of paintings. First, we will give an overview of the advantages of multispectral image analysis over more traditional techniques: first of all, the bands residing in the visible domain provide an accurate measurement of the color information which can be used for analysis but also for conservational and archival purposes (i.e. preserving the art patrimonial by making a digital library). Secondly, inspection of the multispectral imagery by art experts and art conservators has shown that combining the information present in the spectral bands residing in- and outside the visible domain can lead to a richer analysis of paintings. In the remainder of the paper, practical applications of multispectral analysis are demonstrated, where we consider the acquisition of thirteen different, high resolution spectral bands. Nine of these reside in the visible domain, one in the near ultraviolet and three in the infrared. The paper will illustrate the promising future of multispectral analysis as a non-invasive tool for acquiring data which cannot be acquired by visual inspection alone and which is highly relevant to art preservation, authentication and restoration. The demonstrated applications include detection of restored areas and detection of aging cracks.

  1. Computerized tomographic studies in cerebral palsy. Analysis of 200 cases

    Energy Technology Data Exchange (ETDEWEB)

    Sugie, Y. (Tokyo Women' s Medical Coll. (Japan))

    1981-09-01

    Computed tomographic (CT) findings in 200 children with cerebral palsy (CP) were analysed from the viewpoint of clinical manifestations, disease complications and etiological factors. CT scans of 135 cases (67.5%) were found to be abnormal and there were 14 (7%) borderline cases. The major abnormality found on CT scans was cerebral atrophy. Other important changes included focal or diffuse low density area in the brain tissue, congenital malformation, and cerebellar atrophy. From the clinical point of view, a large number of patients with spastic tetraplegia and spastic diplegia showed highly abnormal CT scans. On the other hand, in patients with spastic monoplegia, spastic paraplegia, and athetotic type, CT findings were normal or revealed only minor cerebral atrophy. Most children showing asymmetric clinical symptoms had corresponding asymmetric CT abnormalities which included ventricular enlargement, low density area in the brain tissue, and hemispherical volume. There was a significant correlation between the severity of physical impairment and the extent of CT abnormalities. Severely affected children had grossly abnormal CT scans such as hydranencephaly, polycystic change, and extensive cerebral atrophy. In the patients complicated with epilepsy, the incidence and severity of abnormal CT were higher than those of non-epileptic patients. Mentally retarded patients had variable enlargement of the subarachnoidal space depending on the severity of their mental retardation. Patients with suspected postnatal etiology also had high incidence of severe CT abnormality. CT scan is a valuable tool for evaluating patients with CP and in some cases, possible etiology of the disease may be discovered.

    Krishna, Vikas; Lelescu, Ana

    In today's fast paced world, it is necessary to process business ­documents expediently, accurately, and diligently. In other words, processing has to be fast, errors must be prevented (or caught and corrected quickly), and documents cannot be lost or misplaced. The failure to meet these criteria, depending on the type and purpose of the documents, can have serious business, legal, or safety consequences. In this paper, we evaluated a B2B order placement service system that allows clients to place orders for products and services over a network. We describe the order placement service before and after deploying the Intelligent Document Gateway (IDG), a document-centric business process automation technology from IBM Research. Using service science perspective and service systems frameworks, we provide an analysis of how IDG improved the value proposition for both the service providers and service clients.

  12. Indirect detection analysis: wino dark matter case study

    International Nuclear Information System (INIS)

    We perform a multichannel analysis of the indirect signals for the Wino Dark Matter, including one-loop electroweak and Sommerfeld enhancement corrections. We derive limits from cosmic ray antiprotons and positrons, from continuum galactic and extragalactic diffuse γ-ray spectra, from the absence of γ-ray line features at the galactic center above 500 GeV in energy, from γ-rays toward nearby dwarf spheroidal galaxies and galaxy clusters, and from CMB power-spectra. Additionally, we show the future prospects for neutrino observations toward the inner Galaxy and from antideuteron searches. For each of these indirect detection probes we include and discuss the relevance of the most important astrophysical uncertainties that can impact the strength of the derived limits. We find that the Wino as a dark matter candidate is excluded in the mass range bellow ≅ 800 GeV from antiprotons and between 1.8 and 3.5 TeV from the absence of a γ-ray line feature toward the galactic center. Limits from other indirect detection probes confirm the main bulk of the excluded mass ranges

    2016-02-05

    Two multifamily buildings planned in Climate Zone 4 were analyzed to determine the cost, energy and performance implications of redesigning them to comply with Zero Energy Ready Home, a recognition program of the U.S. Department of Energy. Energy modeling was conducted on one representative apartment in each building using BEopt. Construction costs were obtained from the developer and subcontractors to determine savings and cost increases over ENERGY STAR. It was found that seven items would be necessary to change to comply with ZERH criteria when starting from the original design which was compliant with ENERGY STAR version 3.0. Design changes were made to the exterior walls, domestic water heating system, duct protection, duct design, garage ventilation, and pest control to comply with ZERH requirements. Energy impacts of upgrading from the original design to ZERH resulted in 2 to 8% reduction in modeled source energy consumption, or 1.7 to 10.4 MMBtu per year, although the original design was already about 8% better than a design configured to minimum ENERGY STAR criteria. According to the BEopt analysis, annualized energy related costs of the ZERH design were slightly higher for the apartment and slightly lower for the townhome when compared to the original design.

    Recent progress in the structural analysis of a Hybrid Wing-Body (HWB) fuselage concept is presented with the objective of structural weight reduction under a set of critical design loads. This pressurized efficient HWB fuselage design is presently being investigated by the NASA Environmentally Responsible Aviation (ERA) project in collaboration with the Boeing Company, Huntington Beach. The Pultruded Rod-Stiffened Efficient Unitized Structure (PRSEUS) composite concept, developed at the Boeing Company, is approximately modeled for an analytical study and finite element analysis. Stiffened plate linear theories are employed for a parametric case study. Maximum deflection and stress levels are obtained with appropriate assumptions for a set of feasible stiffened panel configurations. An analytical parametric case study is presented to examine the effects of discrete stiffener spacing and skin thickness on structural weight, deflection and stress. A finite-element model (FEM) of an integrated fuselage section with bulkhead is developed for an independent assessment. Stress analysis and scenario based case studies are conducted for design improvement. The FEM model specific weight of the improved fuselage concept is computed and compared to previous studies, in order to assess the relative weight/strength advantages of this advanced composite airframe technology

Based on a thorough case study of the China-Japan Coke Dry Quenching (CDQ) project, the first approved pilot project in China under the "Activities Implemented Jointly" (AIJ) framework, the paper not only describes in detail the complete procedure of baseline definition of the case project, but also discusses its approach to baseline determination. Furthermore, cost-benefit analysis of GHGs mitigation is conducted according to the baseline. This empirical case study, based on real AIJ project data, will be beneficial for the development of future projects under Kyoto mechanisms such as "Clean Development Mechanism" and "Joint Implementation".

    Full Text Available The aim of this paper is to analyze the key features of an effective complaint management process as well as to explore whether these systems are formally constituted in terms of standards or other models for complaints management. We use four case studies of spa organizations from Spain. The case studies illustrate the organizations' approach to managing complaints and customer satisfaction effectively. The results of this exploratory study show that all four organizations have some mechanisms implemented to handle complaints although different levels of formalization have been achieved. The analysis unveils some common difficulties and key success factors of implementing a complaints handling system. The results of this paper suggest that managers should prioritize managing customer complaints effectively in order to enhance their chances of meeting customer expectations. This strategy can result into turning customer complaints to customer satisfaction, especially when the organization views complaints as an opportunity to improve.

    Full Text Available Starting from the critical review of various motivational frameworks of change that have been applied to the study of eating disorders, the present paper provides an alternative conceptualization of the change in psychotherapy presenting a single case study. We analysed six psychotherapeutic conversations with a bulimic patient and found out narratives for and against change. We read them in terms of tension between dominance and exchange in I-positions, as described by Hermans. These results indicate that the dialogical analysis of clinical discourse may be a useful method to investigate change from the beginning to the end of therapy.

We chose ten typical ecoindustrial parks in China and around the world and compared the degree of network connectedness of these systems that resulted from exchanges of products, byproducts, and wastes. By analyzing the density and nodal degree, we determined the relative power and status of the nodes in these networks, as well as other structural attributes such as the core-periphery structure and the degree of sub-network connectedness. The results reveal the operational problems created by the structure of the industrial networks and provide a basis for improving the degree of completeness, thereby increasing their potential for sustainable development and enriching the methods available for the study of industrial symbiosis.

    2014-02-01

    Full Text Available TTDABC is a relatively new costing management technique, initially developed for manufacturing processes, which is gaining attention in libraries. This is because TDABC is a fast and simple method that only requires two parameters, an estimation of time required to perform an activity and the unit cost per time of supplying capacity. A few case studies have been documented with regard to TDABC in libraries; all of them being oriented to analyse specific library activities such as inter-library loan, acquisition and circulation processes. The primary focus of this paper is to describe TDABC implementation in one of the most important library processes, namely cataloguing. In particular, original and copy cataloguing are analysed through a case study to demonstrate the applicability and usefulness of TDABC to perform cost analysis of cataloguing processes.

    2013-01-01

    Studies related to crowds of pedestrians, both those of theoretical nature and application oriented ones, have generally focused on either the analysis or the synthesis of the phenomena related to the interplay between individual pedestrians, each characterised by goals, preferences and potentially relevant relationships with others, and the environment in which they are situated. The cases in which these activities have been systematically integrated for a mutual benefit are still very few compared to the corpus of crowd related literature. This paper presents a case study of an integrated approach to the definition of an innovative model for pedestrian and crowd simulation (on the side of synthesis) that was actually motivated and supported by the analyses of empirical data acquired from both experimental settings and observations in real world scenarios. In particular, we will introduce a model for the adaptive behaviour of pedestrians that are also members of groups, that strive to maintain their cohesion...

    Full Text Available IntroductionFor recent century human safety and freedom from crime are very important in everyday life. In terms of human needs, Maslow's (1943 hierarchy of needs suggests sustainable environments should cater for biological and physiological, safety, affiliation, esteem, and self-actualization needs — in that order. Crime and freedom from crime are surely high on peoples' agendas of most important issues in many countries worldwide. Geographers deal with the distribution of a wide variety of geographical entities and phenomena amongst human safety and freedom. Geographers analyze the spatial distributions, the pattern of the distribution of objective and subjective phenomena spatial variability and so forth. The concept of spatial analysis deals discovery spatial patterns, causes and effect of phenomena, autocorrelation, etc. Geographers in spatial crime analysis were limited to mapping crimes in locations and regions. Technological improvements, first and foremost in computer processor capabilities, are fundamental to recent analytical advances in the methods available for analyzing place-based data. The initiation of computer mapping applications and additional geographic information systems (GIS are important to being able to measure and represent the spatial relationships in data. ESDA is a collection of techniques to describe and imagine spatial distributions; identify unusual locations or spatial outliers; discover patterns of spatial association, clusters, or hot spots; and suggest spatial regimes or other forms of spatial heterogeneity. Material and MethodsData: In current study used results of census of population and housing 2006 and Residential burglary data of Zahedan as None spatial data and census Zone map of Zahedan(is located southern-east of Iran as spatial data.To measure the spatial distribution, autocorrelation and autoregressive used Moran’s I and LISA index in ArcGIS 9.3 and GeoDA 0.9.3 software.

    International Nuclear Information System (INIS)

    Over the last decade, the time required to measure a terabyte of microscopic imaging data has gone from years to minutes. This shift has moved many of the challenges away from experimental design and measurement to scalable storage, organization, and analysis. As many scientists and scientific institutions lack training and competencies in these areas, major bottlenecks have arisen and led to substantial delays and gaps between measurement, understanding, and dissemination. We present in this paper a framework for analyzing large 3D datasets using cloud-based computational and storage resources. We demonstrate its applicability by showing the setup and costs associated with the analysis of a genome-scale study of bone microstructure. We then evaluate the relative advantages and disadvantages associated with local versus cloud infrastructures

    2014-01-01

    Full Text Available Introduction: Gastric cancer is among the leading causes of cancer-related death worldwide, especially in Eastern Asia, Eastern Europe and South America. Statin is one of the most widely used medications for hypercholesterolemia. Several meta-analyses have failed to determine the relationship between statins and gastric cancer. Aims: A meta-analysis of case control studies is conducted to evaluate the association of statin exposure and risk of gastric cancer. Materials and Methods: Eight electronic databases (The Cochrane Central Register of Controlled Trials (CENTRAL (Issue 12, 2012, PubMed, EMBASE, ISI Web of Knowledge, CNKI, CBM, CSJD and Wanfang Database were searched for relevant publications through September 2013. Two reviewers determined the eligibility of articles and abstracted the data independently. RevMan 5.2 software was used for statistical analysis. Results: 146 items were retrieved from the databases and 6 studies were identified in this meta-analysis, which included 5,993 cases and 54,800 matched controls. Results from the meta-analysis demonstrated that statins were inversely related to the risk of gastric cancer (RR = 0.56, 95% CI: 0.35-0.90. There was no significant difference for cumulative duration of statin exposure and gastric cancer, nor participants from Asia, Europe, or USA. Conclusion: This meta-analysis suggests that statins have favorable effects on gastric cancer, rigorously designed and executed observational studies and randomized control trials with longer duration of follow-up are warranted to determine effects in clinical practice.

  7. Diabetes and risk of Parkinson's disease: an updated meta-analysis of case-control studies.

    Full Text Available BACKGROUND: Whether diabetes increases the risk of Parkinson's disease (PD is still inconclusive. The objective of this updated meta-analysis is to synthesize evidence from case-control studies that evaluated the association between diabetes and the risk of PD. METHODS: Seven databases were searched to identify case-control studies that evaluated the association between diabetes and PD. The methodological quality of included studies was assessed using Newcastle-Ottawa scale. All data were analyzed using Review Manager 5.1 software. Subgroup analyses were also adopted, according to stratification on gender, geographic location, source of the control group, smoking, anti-diabetes drug prescription and duration of DM. RESULTS: Fourteen studies fulfilled inclusion criteria for meta-analysis, yielding a total of 21395 PD patients and 84579 control subjects. Individuals with diabetes were found to have a negative association with future PD (OR 0.75; 95% CI 0.58-0.98 in spite of significant heterogeneity. In subgroup analyses, the negative correlation was still found in studies from North America, non-PD control groups from general population, never smoking individuals, and DM ascertainment based on questionnaire or self-report. Stratification of gender and DM duration showed no significant association. No association was also found in European and Asian individuals, hospital-based controls, ever smoking subjects, DM assessment by medical record or physician diagnosis, and insulin prescription for DM. CONCLUSION: Evidence from case-control studies suggested that diabetic individuals may have a decreased incidence of PD despite significant heterogeneity. More researches are warranted to clarify an understanding of the association between diabetes and risk of PD.

  8. Renewable energy technology portfolio planning with scenario analysis: A case study for Taiwan

    International Nuclear Information System (INIS)

    This paper presents the results of a case study of applying a systematic and proven process of technology portfolio planning with the use of scenario analysis to renewable energy developments in Taiwan. The planning process starts with decision values of technology development based on a survey of society leaders. It then generates, based on expert opinions and literature search, a set of major technology alternatives, which in this study include: wind energy, photovoltaic, bio-energy, solar thermal power, ocean energy, and geothermal energy. Through a committee of technical experts with diversified professional backgrounds, the process in this study next constructs three scenarios ('Season in the Sun', 'More Desire than Energy', and 'Castle in the Air') to encompass future uncertainties in the relationships between the technology alternatives and the decision values. Finally, through a second committee of professionals, the process assesses the importance and risks of these alternative technologies and develops a general strategic plan for the renewable energy technology portfolio that is responsive and robust for the future scenarios. The most important contributions of this paper are the clear description of the systematic process of technology portfolio planning and scenario analysis, the detailed demonstration of their application through a case study on the renewable energy development in Taiwan, and the valuable results and insights gained from the application.

  11. Shutdown Decay Heat Removal analysis of a Westinghouse 3-loop pressurized water reactor: Case study

    International Nuclear Information System (INIS)

    This is one of six case studies for USI A-45 Decay Heat Removal (DHR) Requirements. The purpose of this study is to identify any potential vulnerabilities in the DHR systems of a typical Westinghouse 3-loop PWR, to suggest possible modifications to improve the DHR capability, and to assess the value and impact of the most promising alternatives to the existing DHR systems. The systems analysis considered small LOCAs and transient internal initiating events, and seismic, fire, extreme wind, internal and external flood, and lightning external events. A full-scale systems analysis was performed with detailed fault trees and event trees including support system dependencies. The system analysis results were extrapolated into release categories using applicable past PRA phenomenological results and improved containment failure mode probabilities. Public consequences were estimated using site specific CRAC2 calculations. The Value-Impact (VI) analysis of possible alternatives considered both onsite and offsite impacts arriving at several risk measures such as averted population dose out to a 50-mile radius and dollars per person rem averted. Uncertainties in the VI analysis are discussed and the issues of feed and bleed and secondary blowdown are analyzed

  13. Societal acceptance of wind farms: Analysis of four common themes across Australian case studies

    International Nuclear Information System (INIS)

    Australia's renewable energy target (RET) seeks to provide 20 per cent of Australia's electricity generation from renewable energy sources by 2020. As wind power is relatively advanced, it was anticipated that wind power will contribute a major component of the early target. However, high levels of societal resistance to wind farms, combined with new regulatory policies, indicate the RET may not be dominated by wind power. This research involved an examination of seven case studies around wind farm deployment. Qualitative interviews were the primary data for the case studies and analysed using methods informed by grounded theory. Despite the diversity of stakeholder views, the qualitative analysis identified strong community support for wind farms but four common themes emerged that influence this societal acceptance of wind farms in Australia: trust, distributional justice, procedural justice and place attachment. Without addressing these factors through integration into policy development and engagement approaches, wind energy is unlikely to provide the early and majority of new renewable energy. Similar international experiences are incorporated in the discussion of the Australian wind industry's societal acceptance. - Highlights: ► Seven case studies of wind farms in Australia are described. ► Acceptance affects whether wind significantly contributes to the Aust. RE target. ► Four themes were identified regarding societal acceptance of Australian wind farms. ► Four themes are trust, distributional and procedural justice, and place attachment. ► International similarities to the Australian experience are provided

    Objective Numerous studies have investigated the associations between herpesviruses and chronic periodontitis; however, the results remain controversial. To derive a more precise estimation, a meta-analysis on all available studies was performed to identify the association between herpesviruses and chronic periodontitis. Methods A computerized literature search was conducted in December 2014 to identify eligible case-control studies from the PUBMED and EMBASE databases according to inclusion and exclusion criteria. Data were extracted and pooled odds ratios (OR) with 95% confidence intervals (CI) were used to assess the association between herpesviruses and risk of chronic periodontitis. A fixed or random effects model was determined based on a heterogeneity test. Sensitivity analysis was conducted to investigate stability and reliability. Publication bias was investigated using the Begg rank correlation test and Egger's funnel plot. Results Ten eligible studies were included to investigate the association between Epstein–Barr virus (EBV) and chronic periodontitis. The results showed that EBV has a significant association with chronic periodontitis compared with periodontally healthy group (OR = 5.74, 95% CI = 2.53–13.00, Pherpesvirus 7 (HHV-7) and chronic periodontitis risk (OR = 1.00, 95% CI = 0.21–4.86). Conclusion The findings of this meta-analysis suggest that two members of the herpesvirus family, EBV and HCMV, are significantly associated with chronic periodontitis. There is insufficient evidence to support associations between HSV, HHV-7 and chronic periodontitis. PMID:26666412

    Gap analysis is used to analyse reserve networks and their coverage of biodiversity, thus identifying gaps in biodiversity representation that may be filled by additional conservation measures. Gap analysis has been used to identify priorities for species and habitat types. When it is applied to identify gaps in the coverage of environmental variables, it embodies the assumption that combinations of environmental variables are effective surrogates for biodiversity attributes. The question remains of how to fill gaps in conservation systems efficiently. Conservation prioritization software can identify those areas outside existing conservation areas that contribute to the efficient covering of gaps in biodiversity features. We show how environmental gap analysis can be implemented using high-resolution information about environmental variables and ecosystem condition with the publicly available conservation prioritization software, Zonation. Our method is based on the conversion of combinations of environmental variables into biodiversity features. We also replicated the analysis by using Species Distribution Models (SDMs) as biodiversity features to evaluate the robustness and utility of our environment-based analysis. We apply the technique to a planning case study of the state of Victoria, Australia. PMID:22935646

  17. Human-centered modeling in human reliability analysis: some trends based on case studies

    International Nuclear Information System (INIS)

    As an informal working group of researchers from France, Germany and The Netherlands created in 1993, the EARTH association is investigating significant subjects in the field of human reliability analysis (HRA). Our initial review of cases from nuclear operating experience showed that decision-based unrequired actions (DUA) contribute to risk significantly on the one hand. On the other hand, our evaluation of current HRA methods showed that these methods do not cover such actions adequately. Especially, practice-oriented guidelines for their predictive identification are lacking. We assumed that a basic cause for such difficulties was that these methods actually use a limited representation of the stimulus-organism-response (SOR) paradigm. We proposed a human-centered model, which better highlights the active role of the operators and the importance of their culture, attitudes and goals. This orientation was encouraged by our review of current HRA research activities. We therefore decided to envisage progress by identifying cognitive tendencies in the context of operating and simulator experience. For this purpose, advanced approaches for retrospective event analysis were discussed. Some orientations for improvements were proposed. By analyzing cases, various cognitive tendencies were identified, together with useful information about their context. Some of them match psychological findings already published in the literature, some of them are not covered adequately by the literature that we reviewed. Finally, this exploratory study shows that contextual and case-illustrated findings about cognitive tendencies provide useful help for the predictive identification of DUA in HRA. More research should be carried out to complement our findings and elaborate more detailed and systematic guidelines for using them in HRA studies

    Cases of absorbing aerosols above clouds (AACs), such as smoke or mineral dust, are omitted from most routinely processed space-based aerosol optical depth (AOD) data products, including those from the Moderate Resolution Imaging Spectroradiometer (MODIS). This study presents a sensitivity analysis and preliminary algorithm to retrieve above-cloud AOD and liquid cloud optical depth (COD) for AAC cases from MODIS or similar sensors, for incorporation into a future version of the "Deep Blue" AOD data product. Detailed retrieval simulations suggest that these sensors should be able to determine AAC AOD with a typical level of uncertainty approximately 25-50 percent (with lower uncertainties for more strongly absorbing aerosol types) and COD with an uncertainty approximately10-20 percent, if an appropriate aerosol optical model is known beforehand. Errors are larger, particularly if the aerosols are only weakly absorbing, if the aerosol optical properties are not known, and the appropriate model to use must also be retrieved. Actual retrieval errors are also compared to uncertainty envelopes obtained through the optimal estimation (OE) technique; OE-based uncertainties are found to be generally reasonable for COD but larger than actual retrieval errors for AOD, due in part to difficulties in quantifying the degree of spectral correlation of forward model error. The algorithm is also applied to two MODIS scenes (one smoke and one dust) for which near-coincident NASA Ames Airborne Tracking Sun photometer (AATS) data were available to use as a ground truth AOD data source, and found to be in good agreement, demonstrating the validity of the technique with real observations.

The algorithm is also applied to two MODIS scenes (one smoke and one dust) for which near-coincident NASA Ames Airborne Tracking Sun photometer (AATS) data were available to use as a ground truth AOD data source, and found to be in good agreement, demonstrating the validity of the technique with real observations.

    Volumetric quantification of ore minerals is of interest using non-destructive laboratory X-ray tomography, as it allows high throughput, fast analysis, without any/limited sample preparation. This means traditional chemical analysis can still be performed on the same samples, but good information can be provided in a very short time assisting in exploration, mining and beneficiation decision making as well as sample selection for further chemical analysis. This paper describes a case study in which tungsten WO3/scheelite is quantified in 35 mm diameter drill core samples and compared to subsequent traditional chemical analysis for the same samples. The results show a good correlation and indicates that laboratory X-ray CT scanning could replace the more time consuming traditional analytical methods for ore grading purposes in some types of deposits. Different image processing methods are compared for these samples, including an advanced thresholding operation which reduces operator input error. The method should work equally well for other types of ore minerals in which the mineral of interest is the most dense particle in the scan volume, and for which the bulk of the particle sizes are at least 3 times larger than the scan resolution.

    In this study, we investigated the correlates of aggression among consumers with mental illness within two psychiatric hospitals in Jordan. This was a descriptive, cross sectional study carried out by auditing consumers' medical records in regards to incidents of aggression before and during admission. Approval was gained from 203 next of kins to review the consumers' medical records. Results from this case analysis, found the prevalence of aggressive behaviours among psychiatric inpatient's in Jordan to be 23.6%, the most common form of aggression was consumer to consumer and that the aggressive act was more likely to be perpetrated by younger consumers. Such findings contribute to the discourse about aggression and understanding who and what causes aggression can go toward identify strategies for early intervention and management. After all, mental health units should be places of safety, that is, an asylum, and everyone who enters that environment deserves to be safe. PMID:26538486

    Traditionally, decision-makers have relied on economic impact estimates derived from conventional economy-wide models. Conventional models lack the environmental linkages necessary for examining environmental stewardship and economic sustainability, and in particular the ability to assess the impact of policies on natural capital. This study investigates environmentally extended economic impact estimation on a regional scale using a case study region in the province of Alberta known as the Foothills Model Forest (FMF). Conventional economic impact models are environmentally extended in pursuit of enhancing policy analysis and local decision-making. It is found that the flexibility of the computable general equilibrium (CGE) modeling approach offers potential for environmental extension, with a solid grounding in economic theory. The CGE approach may be the tool of the future for more complete integrated environment and economic impact assessment. PMID:12859004

    2014-02-01

    Full Text Available `Background: In today’s business environment, a company is able to maintain its competitive position if it constantly generates knowledge and disseminates this knowledge within the organization, as well as transforms it into new competences. The ability to transfer knowledge becomes one of the key factors in the improvement of a company’s competitive position. This hypothesis is applicable particularly in the case of cooperation within networks, as they are an excellent opportunity for mutual learning between partners. Objectives: The purpose of the paper is to analyse the process of knowledge transfer in intra-organizational networks. Method: Due to the specificity of the research object, the case study method has been chosen. In order to make an in-depth analysis of the case study, we selected a group of several criteria based on the theory which we believe to be fundamental to the effectiveness of knowledge management in networks, and compared them with the situation in the ArcelorMittal Group. Results: Our research show that ArcelorMittal Group has met almost all the criteria of effective knowledge management in its intra-organizational network. Some exceptions, albeit merely to an extent, are mostly the result of historical circumstances, , i.e. the process of growth through acquisitions, and the acquisition of companies at different stages of organizational development, as well as organizational culture. Conclusion: Based on theoretical assumptions, the study analysed in details the components of knowledge management applied by the corporation in question. Therefore this study might be utilised to formulate a refutable hypothesis and verify them on a larger group of companies from different sectors of the economy. The main limitations of the paper are mostly related to the inherent approach therein

  9. A case study of GAMM (graphical analysis for maintenance management) in the mining industry

    International Nuclear Information System (INIS)

    This paper presents a case for practical application of the GAMM method, which has been developed and published by the authors (Barberá L., Crespo A. and Viveros P.) The GAMM method supports decision-making in the overall maintenance management, through the visualization and graphical analysis of data. In addition, it allows for the identification of anomalous behavior in the equipment analyzed, whether derived from its own operations, maintenance activities, improper use of equipment or even as a result of design errors in the equipment itself. As a basis for analysis, the GAMM method uses a nonparametric estimator of the reliability function using all historical data or, alternatively, part of the history, allowing it to perform an analysis even with limited available data. In the case study developed, GAMM has been used to analyze two slurry pumps in a mining plant located in Chile. Both pumps are part of the same industrial process, which is described in Section 3, and both pumps had a higher failure rate but one more than the other. GAMM identified deficiencies in each of the pumps being studied, thus improving decision-making and problem solving process related to the maintenance of the pumps. Particularly, this work initially provides a description of the GAMM method (Section 1), and, afterwards, it is depicted with special attention the approach to the problem (Section 2). In Section 3, a background of the industrial context is presented. Then, Section 4 shows step by step the application of GAMM method. Finally, results and conclusions are presented in Section 5 where the main improvements obtained are summarized

  10. Strategic analysis methodology for energy systems with remote island case study

    International Nuclear Information System (INIS)

    A strategic analysis methodology is presented for adaptive energy systems engineering to realize an optimal level of service in the context of a community's social, economic, and environmental position. The groundwork stage involves characterizing the social context, assessing available energy resources, identifying environmental issues, setting eco-resource limits, and quantifying socio-economic constraints for a given region. A spectrum of development options is then constructed according to the range of energy service levels identified for the sector under study. A spectrum of conceptual energy systems is generated and infrastructure investments and resource use are modeled. The outcome is a matrix of energy system investment possibilities for the range of energy demand levels reflecting the values, ideas, and expectations expressed by the community. These models are then used to assess technical feasibility and economic, environmental and social risk. The result is an easily understood graphical depiction of local aspirations, investment options, and risks which clearly differentiates development opportunities from non-viable concepts. The approach was applied to a case study on Rotuma, an isolated Pacific Island. The case study results show a clear development opportunity space for Rotuma where desired energy services are in balance with investment sources, resource availability, and environmental constraints.

    2016-07-01

    The swift growth of e-commerce or e-tailing as a consumer retail channel has made it a serious competitor to traditional retail channels and is changing consumers' purchasing behaviour. The purpose of this case study, based on Target and Amazon.com, is to analyse the attributes of traditional retailing, e-tailing, and hybrid supply chain models to form conclusions about the feasibility of an idealised supply chain model for the future. An integrated and generalised modelling framework is used that incorporates Six Sigma - define, measure, analyse, improve, control methodology leveraging various tools, including process flow maps, cause and effect diagram, performance efficiency metrics, failure mode and effects analysis (FMEA), and Monte Carlo simulation. Based on this analysis and research, the conclusion is that the idealised supply chain of the future may evolve into a hybrid supply chain, which includes both e-tail and retail channels. The main recommendations from this study include assessing the risks of migrating to such a hybrid supply chain and to leverage the recommended actions provided in the hybrid FMEA. To facilitate more effective and mature processes, this study can guide researchers in exhaustive empirical evaluations of hybrid supply chains, gather experiences and lessons learned for practitioners.

    This study aimed to comprehensively evaluate factors that influence the likelihood of syphilis infection from risk-taking behaviours and medical conditions. A retrospective case-control study was conducted by enrolling 664 syphilis inpatients (excluding 11 congenital syphilis patients) and 800 sex- and age-matched controls. Medical histories, clinical data and patient interview data were collected and subjected to logistic regression analyses. The prevalence of syphilis in the study population was 3·9% (675/17 304). By univariate analysis, syphilis infection was associated with migration between cities, marital status, smoking, reproductive history, hypertension, elevated blood urea nitrogen (BUN) and infection with hepatitis B virus (HBV) (P syphilis-HBV co-infection was observed in HIV-negative patients and further research revealed an association between syphilis and specific HBV serological reactivity. Syphilis was also associated with the frequency, duration and status of tobacco use. Multivariate analysis indicated that syphilis infection was independently associated with migration between cities [adjusted odds ratio (aOR) 1·368, 95% confidence interval (CI) 1·048-1·785], current smoking (aOR 1·607, 95% CI 1·177-2·195), elevated BUN (aOR 1·782, 95% CI 1·188-2·673) and some serological patterns of HBV infection. To prevent the spread of infectious diseases, inpatients and blood donors should be tested for HIV, syphilis, HBV and HCV simultaneously. PMID:26467944

    1978-11-01

    Application of venture analysis would, at a minimum, need to address issues involving careful definition of the product/service being considered; market needs that the product will satisfy; investment/manufacturing costs; minimum selling price needed to achieve desired ROI or other financial measure; market potential at relevant prices; potential for competitors to obsolete the product before investment is recovered; assessment of companies' resources and capabilities to supply the product. There is clearly no single method for performing every venture analysis, because the economic and structural environment associated with each industry varies widely. These and other factors produce differences in cost structure, marketing organizations, and nature of products which dictate that an appropriate method of venture analysis must be tailored to each industry. The initial chapter of the report presents some brief remarks concerning the important concepts that all venture analyses must consider and then describes in detail the method used for the venture analyzed in this report. The case study addresses IEUS for commercialization. The type of IEUS investigated supplies electricity and thermal energy; the thermal energy distributed in the form of high-temperature water, i.e., water from at least 90/sup 0/C upwards to 200/sup 0/C.

    Full Text Available Along with the growth of the Internet, the trend shows that e-commerce have been growing significantly in the last several years. This means business opportunities for small-medium enterprises (SMEs, which are recognized as the backbone of the economy. SMEs may develop and run small to medium size of particular e-commerce websites as the solution of specific business opportunities. Certainly, the websites should be developed accordingly to support business success. In developing the websites, key elements of e-commerce business model that are necessary to ensure the success should be resolved at the requirement stage of the development. In this paper, we propose an enhancement of requirement analysis method found in literatures such that it includes activities to resolve the key elements. The method has been applied in three case studies based on Indonesia situations and we conclude that it is suitable to be adopted by SMEs.

    This paper presented a method for predicting shaft station radon concentrations in a uranium mine of China through theoretical analysis, mathematical derivation and Monte-Carlo simulation. Based upon the queuing model for tramcars, the average waiting time of tramcars and average number of waiting tramcars were determined, which were further used in developing the predictive model for calculating shaft station radon concentrations. The results exhibit that the extent of variation of shaft station radon concentration in the case study mine is not significantly affected by the queuing process of tramcars, and is always within the allowable limit of 200 Bq m(-3). Thus, the empirical limit of 100,000 T annual ore-hoisting yields has no value in ensuring radiation safety for this mine. Moreover, the developed model has been validated and proved useful in assessing shaft station radon levels for any uranium mine with similar situations. PMID:27100335

    In an era of increasing global competition and an increased interest in global clinical studies Japan has been concerned with the risk of losing its attractiveness due to perceived longer execution times and higher cost structure. In contrast, other Asian countries particularly China and Singapore are widely recognized as potential key centers for fast conduction of global clinical studies. We conducted a case comparison based on two clinical studies performed by a multinational pharmaceutical company in order to measure the productivity of clinical studies by region and country. We focused on the site-related study cost which constituted the largest portion of the cost breakdown and also impacted both time and quality management. For investigation of the productivity we propose a breakdown model with two Key Performance Indicators (KPIs), enrollment efficiency and site-related cost efficiency, for the comparison of the number of enrolled subject per site and cost, respectively. Through the comparative analysis we found that the Asian countries (excluding Japan) on average achieved higher efficiency than Japan in both indicators. In the Asian group, China and Singapore stood out as the most efficient on both speed and site-related cost. However, when the site-related cost efficiency was adjusted for Purchasing Power Parity (PPP) the cost advantage in China disappeared, implying the price level was critical for productivity management. Although quality aspects remain to be investigated we postulate that introducing a comparative approach based on a productivity framework would be useful for an accurate productivity comparison.

    Full Text Available In today's competitive world, customers are demanding better quality products with fast and reliable deliveries. To meet this demand, new manufacturing technologies are developing rapidly, resulting in new products and improvements in manufacturing processes. As part of this effort, lean production principles have been established and are in use in developed countries to minimize and/or remove wastes.The purpose of this study is to identify and analyse lean wastes surfacing in production lines of four textile and garment industries. The information will make it possible for them to minimize or eliminate lean wastes using recommended tools and techniques. As a result, a smooth working environment will be created which will improve the plants’ ability to produce exactly the right quantity with the right quality and at exactly the right time, with a minimum of interruption. This study has followed qualitative and quantitative research approaches for collecting and analysing the data of the four cases chosen. The main methods used for data collection are questionnaires, shop floor visits, and check sheets. The empirical findings are analysed using appropriate tools of investigation and by theoretical concepts of lean production and economic cost analysis.The aggregate data collected over time show that there is substantial waste in the production process from the start of producing products to the day of delivery, using all available resources. Furthermore, the result of the analysis mainly demonstrates that there is an inconsistent production rate per shift, and noticeable employee turnover.

    Full Text Available This paper presents the rationale behind performing an analysis of Internet resilience in the sense of maintaining a connection of autonomous systems in the presence of failures or attacks — on a level of a single country. Next, the graph of a network is constructed that represents interconnections between autonomous systems. The connectivity of the graph is examined for cases of link or node failure. Resilience metrics are proposed, focusing on a single autonomous system or on overall network reliability. The process of geographic location of networking infrastructure is presented, leading to an analysis of network resilience in the case of a joint failure of neighboring autonomous systems.

    Full Text Available A simulation model is developed for optimal sizing and analysis of a PV-diesel-battery based hybrid power generation system with the objectives to minimize life cycle cost and CO2 emission, while maintaining the desired system autonomy. A case study of a boy’s hostel in Moradabad district is taken for analysis purposes. It has 91 rooms with a capacity of 3 boys in each room. The decision variables included in the optimization methodology are total PV area, number of PV modules of 600 Wp, diesel generator power, fuel consumption per year and number of 24 V and 150 Ah batteries. The simulation result shows that the PV percentage of 86 % and diesel penetration of 14 % gives the most optimized solution with minimum LCC of $110,547 and average CO2 emission of 28 kg/day. The developed model has been validated by comparing its results with earlier research work.doi:10.14456/WJST.2014.24

    2009-11-01

    Although prospective logistic regression is the standard method of analysis for case-control data, it has been recently noted that in genetic epidemiologic studies one can use the "retrospective" likelihood to gain major power by incorporating various population genetics model assumptions such as Hardy-Weinberg-Equilibrium (HWE), gene-gene and gene-environment independence. In this article we review these modern methods and contrast them with the more classical approaches through two types of applications (i) association tests for typed and untyped single nucleotide polymorphisms (SNPs) and (ii) estimation of haplotype effects and haplotype-environment interactions in the presence of haplotype-phase ambiguity. We provide novel insights to existing methods by construction of various score-tests and pseudo-likelihoods. In addition, we describe a novel two-stage method for analysis of untyped SNPs that can use any flexible external algorithm for genotype imputation followed by a powerful association test based on the retrospective likelihood. We illustrate applications of the methods using simulated and real data. © Institute of Mathematical Statistics, 2009.

    Reza A. Maleki

    2011-05-01

    Full Text Available This case study paper is the result of a project conducted on behalf of a company, hereon referred to as Midwest Assembly and Manufacturing or MAAN. The company's operations include component manufacturing, painting, and assembling products. The company also purchases a relatively large percentage of components and major assemblies that are needed to support final assembly operations. MAAN uses its own returnable containers to transport purchased parts from suppliers. Due to poor tracking of the containers, the company has been experiencing lost containers and occasional production disruptions at its facility well as at the supplier sites. The objective of this project was to develop a proposal to enable MAAN to more effectively track and manage its returnable containers. The research activities in support of this project included the analysis and documentation of both the physical flow and the information flow associated with the containers as well as some of the technologies that can help with automatic identification and tracking of containers. The focal point of this paper is on a macro?level approach for the analysis of container and information flow within the logistics chain. A companion paper deals with several of the automatic identification technologies that have the potential to improve the management of MAAN's returnable containers.

  10. Structural Analysis of Single-Point Mutations Given an RNA Sequence: A Case Study with RNAMute

    Churkin, Alexander; Barash, Danny

    2006-12-01

    We introduce here for the first time the RNAMute package, a pattern-recognition-based utility to perform mutational analysis and detect vulnerable spots within an RNA sequence that affect structure. Mutations in these spots may lead to a structural change that directly relates to a change in functionality. Previously, the concept was tried on RNA genetic control elements called "riboswitches" and other known RNA switches, without an organized utility that analyzes all single-point mutations and can be further expanded. The RNAMute package allows a comprehensive categorization, given an RNA sequence that has functional relevance, by exploring the patterns of all single-point mutants. For illustration, we apply the RNAMute package on an RNA transcript for which individual point mutations were shown experimentally to inactivate spectinomycin resistance in Escherichia coli. Functional analysis of mutations on this case study was performed experimentally by creating a library of point mutations using PCR and screening to locate those mutations. With the availability of RNAMute, preanalysis can be performed computationally before conducting an experiment.

    Full Text Available In this paper, the exergy analysis of “(56MW thermal power plant Raipur (India; a case study” are presented. The main objectives of this paper are to analyze the plant’s component separately and to identify the parts having largest exergy losses. This paper will also justify the major sources of losses and exergy destruction in the power plant. According to the study, percentage ratio of the exergy destruction to the total exergy destruction was found to be maximum in the boiler system (57 % followed by the turbine (33.3%, and then the condenser (5.34%. the exergy efficiency of the power plant was 31.12%. Which are low compared to modern power plants. According to analysis found that boiler is the major source of irreversibility in the power plant, but exergy destruction rate in boiler can be reduced by reheating the system. It is a suitable technique for decrease boiler’s irreversibility. How reheating is the best tool for improvement of overall performance and comparison to the real condition of power plant is also presented in this paper. Without any change of fuel consumption, how reheating minimized exergy destruction, has also be investigated.

Previously, the concept was tried on RNA genetic control elements called "riboswitches" and other known RNA switches, without an organized utility that analyzes all single-point mutations and can be further expanded. The RNAMute package allows a comprehensive categorization, given an RNA sequence that has functional relevance, by exploring the patterns of all single-point mutants. For illustration, we apply the RNAMute package on an RNA transcript for which individual point mutations were shown experimentally to inactivate spectinomycin resistance in Escherichia coli. Functional analysis of mutations on this case study was performed experimentally by creating a library of point mutations using PCR and screening to locate those mutations. With the availability of RNAMute, preanalysis can be performed computationally before conducting an experiment.

    2016-07-01

    Full Text Available A greenhouse containing an integrated system of photovoltaic panels, a water electrolyzer, fuel cells and a geothermal heat pump was set up to investigate suitable solutions for a power system based on solar energy and hydrogen, feeding a self-sufficient, geothermal-heated greenhouse. The electricity produced by the photovoltaic source supplies the electrolyzer; the manufactured hydrogen gas is held in a pressure tank. In these systems, the electrolyzer is a crucial component; the technical challenge is to make it work regularly despite the irregularity of the solar source. The focus of this paper is to study the performance and the real energy efficiency of the electrolyzer, analyzing its operational data collected under different operating conditions affected by the changeable solar radiant energy characterizing the site where the experimental plant was located. The analysis of the measured values allowed evaluation of its suitability for the agricultural requirements such as greenhouse heating. On the strength of the obtained result, a new layout of the battery bank has been designed and exemplified to improve the performance of the electrolyzer. The evaluations resulting from this case study may have a genuine value, therefore assisting in further studies to better understand these devices and their associated technologies.

  17. Error analysis of hybrid photovoltaic power forecasting models: A case study of mediterranean climate

    International Nuclear Information System (INIS)

    Highlights: • Hybrid statistical models were implemented for photovoltaic power forecast. • Artificial Neural Networks and Least Square Support Vector Machines are compared. • A deep error analysis is carried out to evaluate the forecasting performance. • Imbalance penalties were evaluated for the different prediction methods. • LS-SVM with Wavelet Decomposition (WD) outperforms ANN method. - Abstract: The advancement of photovoltaic (PV) energy into electricity market requires efficient photovoltaic power prediction systems. Furthermore the analysis of PV power forecasting errors is essential for optimal unit commitment and economic dispatch of power systems with significant PV power penetrations. This study is focused on the forecasting of the power output of a photovoltaic system located in Apulia – South East of Italy at different forecasting horizons, using historical output power data and performed by hybrid statistical models based on Least Square Support Vector Machines (LS-SVM) with Wavelet Decomposition (WD). Five forecasting horizons, from 1 h up to 24 h, were considered. A detailed error analysis, by mean error and statistical distributions was carried out to compare the performance with the traditional Artificial Neural Network (ANN) and LS-SVM without the WD. The decomposition of the RMSE into three contributions (bias, standard deviation bias and dispersion) and the estimation of the skewness and kurtosis statistical metrics provide a better understanding of the differences between prediction and measurement values. The hybrid method based on LS-SVM and WD out-performs other methods in the majority of cases. It is also evaluated the impact of the accuracy of the forecasting method on the imbalance penalties. The most accurate forecasts permit to reduce such penalties and thus maximize revenue

    Full Text Available Abstract Objectives To review and assess (i the factors that facilitate the development of sustainable health policy analysis institutes in low and middle income countries and (ii the nature of external support for capacity development provided to such institutes. Methods Comparative case studies of six health policy analysis institutes (3 from Asia and 3 from Africa were conducted. In each region an NGO institute, an institute linked to government and a university based institute were included. Data collection comprised document review, semi-structured interviews with stakeholders and discussion of preliminary findings with institute staff. Findings The findings are organized around four key themes: (i Financial resources: three of the institutes had received substantial external grants at start-up, however two of these institutes subsequently collapsed. At all but one institute, reliance upon short term, donor funding, created high administrative costs and unpredictability. (ii Human resources: the retention of skilled human resources was perceived to be key to institute success but was problematic at all but one institute. In particular staff often moved to better paid positions elsewhere once having acquired necessary skills and experience, leaving remaining senior staff with heavy workloads. (iii Governance and management: board structures and roles varied according to the nature of institute ownership. Boards made important contributions to organizational capacity through promoting continuity, independence and fund raising. Routine management systems were typically perceived to be strong. (iv Networks: linkages to policy makers helped promote policy influences. External networks with other research organizations, particularly where these were longer term institutional collaborations helped promote capacity. Conclusions The development of strong in-country analytical and research capacity to guide health policy development is critical, yet

    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

    2009-01-01

    Following similar derivation of quasi-geostrophic Q vector (QG), a new Q vector (QN) is constructed in this study. Their difference is that the geostrophic wind in quasi-geostrophic Q vector is replaced by the wind in QN vector. The diagnostic analysis of QN vector is compared with that of QG vector in the case study of a typical Meiyu front cyclone (MYFC) occurred over Changjiang-Huaihe regions during 5-6 July 1991. The results show that the QN vector has more diagnostic advantages than QG vector does. Convergence of QN vector at 700 hPa is found to be a good indicator to mimic the horizontal distribution of precipitation. QN vector is further partitioned into four components: QalstN (along-stream stretching), QcurvN (curvature) QshdvN (shear advection), and QalstN (cross-stream stretching) in a natural coordinate system with isohypse (PG partitioning). The application of QN PG partitioning in the MYFC torrential rain indicates that PG of QcurvN on rainfall enhancement fade from the mature stage to decay stage. QshdvN enhances precipitation significantly as the MYFC develops, and the effect weakens rapidly when the MYFC decays during its eastward propagation. QcrstN shows little impacts on rainfall during the onset and mature phases whereas it displays significant role during the decay phase.QalstN and QcurvN, QshdvN and QcrstN show cancellation only during the decay period.

    Full Text Available Institutions of Higher Education in Brazil (IFES play an important role in the country’s social and scientific development. Focused mainly on teaching, research and extension activities, the IFES are backed by support foundations aimed to the management of financial, human and material resources. Characterized as public bodies, the support foundations are governed by Law no 8.666/93 in what concerns the procurement of goods and services. Therefore, the present study is aimed to develop a model to assist the managers of such foundations in the selection of suppliers to participate in bidding processes that use invitation for bids. Therefore, we conducted a case study in one of the 55 foundations that support Brazilian federal universities. The intervention tool used was the Analytic Hierarchy Process (AHP. Firstly, we established the hierarchy of criteria for problem-solving. Then, a paired comparison was made between criteria for the same level. Subsequently, the consistency analysis of comparison matrices was verified. Finally, the relative priorities of each criterion were obtained and the objective function of the model was constructed. The model was tested through the assessment of the performance of three potential suppliers of IT equipment, and the result was legitimized by decision makers who found the instrument a valid tool to aid in making decisions on supplier selection for the foundation.

    The efficient market hypothesis (EMH) states that asset prices fully reflect all available information. As a result, speculators cannot predict the future behavior of asset prices and earn excess profits at least after adjusting for risk. Although initial tests of the EMH were performed on stock market data, the EMH was soon applied to other markets including foreign exchange (FX). This study uses the detrended fluctuation analysis (DFA) technique to test 01:12:2005-18:04:2010 Iranian Rial/US Dollar exchange rate time series data to see if it can be explained by the weak form of the EMH. Moreover, to determine changes in the degree of inefficiency over time, the whole period has been divided into four subperiods. The study shows that the Iranian Forex market (the Rial/Dollar case) is weak-form inefficient over the whole period and in each of the subperiods. However, the degree of inefficiency is not constant over time. The findings suggest that profitable risk-adjusted trades could be made using past data.

    This series of three case studies illustrates the validity and usefulness of MIDAS, a microcomputer-based tool for integrated resource planning under uncertainty. The first, at Union Electric, serves to test and validate the model and to illustrate its use for demand/supply option evaluation. Focusing on nuclear plant life extension, the Virginia Power case demonstrates the model's extensive detail, particularly in the production cost and financial areas, as well as its flexibility in addressing approximately 70 uncertainty scenarios. Puget Sound Power Light, the third case, used MIDAS for the preparation of its integrated resource plan. A 108-endpoint decision tree illustrates the full power of the decision analysis capability.

    th District have been considered as point events.     Discussion of Results & Conclusions   Among Iran's cities, Tehran has the highest rate of social pathologies because of specific, spatial, physical and social conditions. This positive relationship between population growth and increase in the rate of social Pathologies can be regarded as a result of quantitative increase in the city's population. So it is essential to, with scientific methods and new technologies, identify place-time circumstances in which crimes are committed in Tehran. Tehran's 12th district with 1600 hectares equivalent to 2/7 percent of the total area of Tehran has allocated according to statistics 3.17 percent of the total population of Tehran. Evaluation of the relative density of population in 12th district show that in these area 154.5 people live per hectare, while the relative density of population in Tehran is 131.6 people per hectare. Therefore relative density of population in district 12 of Tehran is greater than the average density in Tehran city.   The findings show that although district 12, only has allocated 2.7 percent of the land area, but the most percentage occurrence of social pathologies occurred in this area of Tehran. In other words, from 6006 cases of studied crime in this study that occurred in Tehran, about 560 cases, occurred in the 12th district.   Based on the time analysis which determines the type and extent of crime in the 12th district, the peak time and the time center of gravity of crimes is 13 and Wednesday, with frequency of 10-8 crime events in this hour and day. Also on the same time at 12:30 to 13:30, 8-6 cases of crime occurs. The findings show that the average center of crimes related to drugs on 12 district is coincided largely with the geographical center of this region, on the streets of Nasser Khosrow , leading to the 15 Khordad street. Standard deviation ellipse of this type of crimes has mode circle, which represents the geographic

    The effort has been done to effectively improve the maintenance method of emergency diesel generator (EDG) by changing from time based maintenance to condition based maintenance (CBM) in nuclear power plant. Technologies of engine signature analysis to evaluate the diesel generator condition have been applied to CBM for EDG in domestic and foreign nuclear power plants. Engine signature analysis includes both combustion analysis and vibration and ultrasonic analysis. Combustion analysis provides information on the combustion performance of the individual cylinders of the diesel engine. Vibration and ultrasonic analysis provides information on event timing and mechanical condition within the diesel engine. These signatures are collected non-intrusively during a normal loaded engine run. The primary impetus for the use of engine signature analysis has been as part of a program to replace the traditional time based open and inspection maintenance program imposed on plants by the original equipment manufacturers. Condition-based maintenance programs based largely on the use of engine signature analysis have increased the reliability and availability of diesel engine. The results of signature analysis on various cases in EDG of KHNP and overseas nuclear power plants are described in this paper

  10. Life cycle carbon emission flow analysis for electricity supply system: A case study of China

    International Nuclear Information System (INIS)

    The carbon emission embodied in trade is fundamental for allocation of responsibility between producers and consumers. This paper quantitatively analyzes embodied carbon emissions along the life cycle of electricity supply, based on network theory. A modified carbon emission flow model is established, based on life cycle assessment considering power losses. There is also a case study of China's interregional electricity supply system in 2010, focusing on two carbon emission carriers, electricity coal transportation and electricity transmission. Results show that the total carbon emission flow reached 169.355 MtCO2eq, i.e., 4.67% of the life cycle carbon emission. Of this, 61.1% was carried by electricity coal transportation before power generation and transmission, owing to an uneven distribution of coal resources. The eastern and southern regions are the major net sinks of carbon emission flows, representing 52.9% and 27.8% of the total, respectively, because of their enormous energy imports. In contrast, the Sanxi region and central China are major net sources of carbon emission flow. The proposed model may help allocate environmental responsibility among different regions, to guarantee balanced trans-regional development. - Highlights: • Hybrid model of LCA and carbon emission flow analysis is established. • Power supply system of China is abstracted as topological network. • Half of the carbon emission flow is carried by fuel transportation system

For each of these vulnerabilities, we describe the potential risks associated with leaving them unattended in a software program, and provide the solutions (including the code snippets in Java that can be incorporated to remove these vulnerabilities. The proposed solutions are very generic in nature, and can be suitably modified to correct any such vulnerabilities in software developed in any other programming language.

  12. Standoff detection and analysis of dust and particles : the state of the art and case studies

    International Nuclear Information System (INIS)

    Point sensors that use vacuum approaches to collect air samples are not well suited for real-time measurements or monitoring of aerosols or dust in large areas, such as mining environments. This paper demonstrated that developments in LiDAR (light detection and ranging) technologies offer capabilities for simple detection of dust particles as well as in-situ assessment of aerosol composition. LiDAR options also include the localization of remote dust clouds, the measurement of their concentration and constituent analysis. The technique involves probing the dust contaminated zones with a laser beam and measuring the level of backscattered light with a collocated detection system. Information regarding the location or content of a dust cloud can be obtained from either elastic response or inelastic response. This presentation included case studies that demonstrated the many technologies developed at Quebec City-based INO for aerosol detection. The technologies included simple range-finding of remote objects, cloud mapping and more complex spectroscopic technologies based on optical inelastic scattering such as laser-induced fluorescence and Raman scattering for particulate identification. The presentation also described the advantages and limitations of the technologies and their suitability for specific mining industry requirements. LiDAR with remote sensing capabilities for dust detection proved to be useful, reliable and affordable. 10 refs., 19 figs.

In the marketing activity of each destination, the analysis of the importance of destination’s resources represents an essential step, however, as the multifaceted tourism product presents (in combination with, as well as through other policies – price, distribution etc. a strong diversification, the distinction between the real, objective situation of the destination’s resources and the lack of their communication, on the one hand, and the distinction between the real situation and the way in which the resources are “presented” (in the direction of maximising or minimising them, on the other hand, can constitute a barrier in the path of formulating and/or fulfilling the marketing objectives and, respectively, the communication ones. In this context, in the authors’ opinion, in aid of a positioning strategy as accurate as possible – starting point in the integrated marketing communication strategy, a radiography of the tourism resources, their place and their reflection, in relation to those communicated through the different promotional instruments (examples, books, guides, online tourism agencies, social media etc., is permanently imposed, all the more in the case of a macrodestination like Romania, and should be carefully monitorised.

    Full Text Available Accurate estimation of flood frequency is needed for the designing of various hydraulic structures such as dam, spillways, barrage etc. Different approaches were presented which uses the conventional moments to extract order statistics such as mean, standard deviation, skewness, kurtosis. Due to problems arising from data quality, such as short record and outliers, conventional moments are problematic. Hosking (1990 developed L-Moments which are linear combinations of order statistics. The main advantage of L-Moments over conventional moments is that they suffer less from the effects of sampling variability. They are more robust to outliers and virtually unbiased for small samples. In this study the L-Moments based method of Regional Flood Frequency Analysis is mentioned and Narmada Basin is considered as a case. The L-Moments have been used for parameter estimation of Generalized Extreme Value (GEV distribution. Regional flood frequency relationship for the chosen basin is developed utilizing GEV distribution. A relationship between mean annual flood and catchment area is obtained which is further employed to generate Regional Flood Formula for ungauged catchment of Narmada Basin. The developed Regional flood formula is used for T-Year return period flood estimation, knowing only one parameter i.e. catchment area of ungauged watershed.

    2011-12-01

    Full Text Available Practice proved that strategic planning is a necessary process for insurance companies. This process can help companies to adapt more easily to environmental changes. The strategic planning of the activity of an insurance company cannot be realized without a careful analysis of the evolution of the market and without studying the company's market position. A classic model used in the portfolio analysis is the Boston Consulting Group model. In this paper we have used the model for studying the activity of the leader of the Romanian insurance market. In 2009 Alliantz Tiriac had 17 types of insurance in the portfolio. Each class of insurance was considered a strategic business unit. We have studied the insurance portfolio by using secondary data from specialized publications, such as the Romanian Insurance Supervisory Commission. Using the data, we have calculated for Alliantz Tiriac, for each class of insurance, the relative market share. The company was leader on the market for five classes of insurance. The economic crisis had a severe impact on the evolution of the Romanian insurance market: from the 17 classes of insurance studied: nine had registered a decrease of the market, eight had registered an increase, but only for three of them the growth exceeded 10%. Using the relative market share and the market growth we have identified the “cash cows”: there are five classes of insurance in this category, among which the “Insurance for land vehicles (CASCO” which represented more than half of the sales (55.82%; unfortunately, in the case of this insurance type there was a very significant decrease of the market in 2010 compared to 2009: -25.12%, the “question marks” – there are three classes of insurance in this category, and the “dogs”. Due to the crisis, a large number of the company's products are in this category and there are no “star” products. This work was supported by CNCSIS – UEFISCSU, project number 915 / 2009

Results: Half of the cases had a verrucous clinical appearance, while the rest presented as papules, plaques, or patches. All the cases showed immature hair follicles, and 24% of cases showed immature sebaceous glands. Normal terminal hair follicles were characteristically absent in the lesion. Nineteen percent of the cases showed dilated apocrine glands, and 14% showed hyperplasia of eccrine glands. Epidermal changes in the form of acanthosis, papillomatosis, and hyperkeratosis were seen in 86% of cases. Dilated keratin-filled infundibula were observed in 24% of cases. One case was associated with a squamous cell carcinoma. Conclusions: Nevus sebaceus is a cutaneous hamartoma, consisting of various elements indigenous to the organ. Normal terminal hair follicles are characteristically absent in the lesion although the same may be seen in rest of the epidermis, a feature of diagnostic importance, not usually highlighted in literature. The divergent differentiation observed in NS is consistent with the common embryologic origin of the folliculosebaceous-apocrine unit and should not mislead the pathologist.

    GWAS have emerged as popular tools for identifying genetic variants that are associated with disease risk. Standard analysis of a case-control GWAS involves assessing the association between each individual genotyped SNP and disease risk. However, this approach suffers from limited reproducibility and difficulties in detecting multi-SNP and epistatic effects. As an alternative analytical strategy, we propose grouping SNPs together into SNP sets on the basis of proximity to genomic features su...

    Salmonella is an important cause of human illness. Disease is frequently associated with foodborne transmission, but other routes of exposure are recognized. Identifying sources of disease is essential for prioritizing public health interventions. Numerous case-control studies of sporadic...... salmonellosis have been published, often using different methodologies and settings. Systematic reviews consist of a formal process for literature review focused on a research question. With the objective of identifying the most important risk factors for salmonellosis, we performed a systematic review of case......-control studies and a meta-analysis of obtained results. Thirty-five Salmonella case-control studies were identified. In the meta-analysis, heterogeneity between studies and possible sources of bias were investigated, and pooled odds ratios estimated.

    Full Text Available The democratization of Post-Soviet states in past two decades is the subject of this academic study. The main question of this research is that why most of the Post-Soviet states haven’t gone through successful transition to democracy. Five countries; Azerbaijan, Belorussia, Georgia, Lithuania and Uzbekistan are the casesof this study to analyze and evaluate as empirical part of this work. I haven’t chosen the countries that have standard and equal level of success or failure. For instance, Lithuania is among those countries that have gone through quite successful process of democratization, whereas others have similar or different problems hindering the full-fledged democratization across the Post-Soviet area. Insome other cases, such as in Georgia the transition has not been fully successful but some measures of democracy are considered to be existent in state institutions and society. Several hypotheses have been developed throughout this study all arguing the preconditions that lead to democratization, then these hypotheses are checked ifthey are applicable in the cases used in this study. The conclusion is that not all these hypotheses are correct in every single case and each case study has its own characteristic causes that lead to failure or success in transition to democracy.

  5. Hidden costs of a typical embodied energy analysis: Brazilian sugarcane ethanol as a case study

    International Nuclear Information System (INIS)

    Worldwide human production systems are tightly coupled to fossil-based energy, the source of which will not be available at low cost in the foreseeable future. Alternative energy sources are being sought for, among which those derived from biomass are considered to have great potential. Brazilian ethanol sugarcane produced at a large scale is being classified in scientific papers and politics as a renewable energy source. However, only the energy return on investment (EROI) and/or the amount of CO2 released to atmosphere have been considered as indicators of renewability. This work aims to discuss some theoretical points, within an embodied energy analysis, that make its use inappropriate for answering all issues related to the concept of renewability. Emergy accounting (with an “m”) is used as a comparative tool and the Brazilian sugarcane ethanol is evaluated as case study. An EROI of 6.7 for ethanol was obtained, showing that for each unit of “commercial energy” invested within the process, 6.7 units of another kind of energy is obtained – this index shows an excellent value for energy efficiency, but it does not reflect the renewability of ethanol. On the other hand, emergy accounting shows a renewability index of 19%, indicating a low rating for sugarcane ethanol. All scientific methodologies available to assess potential energy sources have their pros and cons, but the analyst must be aware that each methodology supplies different indicators with different meanings. Energy analysts should use methodologies appropriately, avoiding wider conclusions not actually represented by indices calculated. - Highlights: • The renewability discourse of biofuels is discussed focusing on the Brazilian sugarcane ethanol. • Both energy efficiency and CO2 emitted hardly indicate the renewability of biofuels. • Emergy evaluation is introduced as a potential tool when assessing renewability. • Analysts must use methodologies accordingly and avoid general

    Directory of Open Access Journals (Sweden)

    Pei-yue Jiang

    Full Text Available BACKGROUND: Previous epidemiological studies have shown that fish consumption may modify the risk of ovarian cancer. However, these studies yielded controversial results. The present meta-analysis was undertaken to evaluate the relationship between fish intake and ovarian cancer risk. METHODS: A literature search was carried out using Pubmed, Embase, and Cochrane Library Central database for all relevant studies up to August 2013. We pooled the relative risks (RR from individual studies using fixed-effect or random-effect model, and carried out heterogeneity and publication bias analyses. RESULTS: A total of 15 (ten case-control, and five cohort studies were included in the present meta-analysis, representing data for 889,033 female subjects and 6,087 ovarian cancer cases. We found that total fish intake was not significantly associated with the risk of ovarian cancer among cohort studies (RR = 1.04 95% CI [0.89, 1.22] as well as case-control studies (RR = 0.90, 95% CI [0.73,1.12]. There was no evidence of publication bias as suggested by Begg's test (P = 0.55 and Egger's test(P = 0.29. CONCLUSIONS: The present meta-analysis showed that total fish consumption was not significantly associated with the risk of ovarian cancer. Further analysis on different fish species and food preparation methods should be conducted in future studies.

  12. Multiple case study analysis of young women's experiences in high school engineering

    Science.gov (United States)

    Pollock, Meagan C.

    richly describe the diversity of experiences. A multiple case study analysis, this study answers the question: How do gender, class, race, and other components of intersectionality, influence high school females' experiences in engineering? Nine young women taking a high school engineering course in a suburban high school in Central Texas during the school year 2011-2012 volunteered to participate. The students were observed in their engineering classes for half of the spring 2012 semester, with bi-weekly interviews with the students, monthly interviews with the teacher, and a single interview with a parent of each volunteer. The nine rich case studies provide us with new stories that help prevent us from narrowing the experiences of women to a single incomplete stereotype, because these young women vary across race, socioeconomic backgrounds, and sexual orientation. Although each story is unique, there are commonalities among their experiences, including family, influence, classroom environment, biases, and beliefs. By drawing from their collective experiences in high school engineering, the findings direct us toward recommendations for educators, parents, engineering curriculum developers, designers of teacher professional development, and future research to improve equity and access for every student in engineering.

    alternative incentive approaches on utility shareholders and customers if energy efficiency is implemented under various utility operating, cost, and supply conditions.We used and adapted a spreadsheet-based financial model (the Benefits Calculator) which was developed originally as a tool to support the National Action Plan for Energy Efficiency (NAPEE). The major steps in our analysis are displayed graphically in Figure ES- 1. Two main inputs are required: (1) characterization of the utility which includes its initial financial and physical market position, a forecast of the utility?s future sales, peak demand, and resource strategy to meet projected growth; and (2) characterization of the Demand-Side Resource (DSR) portfolio ? projected electricity and demand savings, costs and economic lifetime of a portfolio of energy efficiency (and/or demand response) programs that the utility is planning or considering implementing during the analysis period. The Benefits Calculator also estimates total resource costs and benefits of the DSR portfolio using a forecast of avoided capacity and energy costs. The Benefits Calculator then uses inputs provided in the Utility Characterization to produce a ?business-as usual? base case as well as alternative scenarios that include energy efficiency resources, including the corresponding utility financial budgets required in each case. If a decoupling and/or a shareholder incentive mechanism are instituted, the Benefits Calculator model readjusts the utility?s revenue requirement and retail rates accordingly. Finally, for each scenario, the Benefits Calculator produces several metrics that provides insights on how energy efficiency resources, decoupling and/or a shareholder incentive mechanism impacts utility shareholders (e.g. overall earnings, return on equity), ratepayers (e.g., average customer bills and rates) and society (e.g. net resource benefits).

  1. VGC ANALYZER: A SOFTWARE FOR STATISTICAL ANALYSIS OF FULLY CROSSED MULTIPLE-READER MULTIPLE-CASE VISUAL GRADING CHARACTERISTICS STUDIES.

    Science.gov (United States)

    Båth, Magnus; Hansson, Jonny

    2016-06-01

    Visual grading characteristics (VGC) analysis is a non-parametric rank-invariant method for analysis of visual grading data. In VGC analysis, image quality ratings for two different conditions are compared by producing a VGC curve, similar to how the ratings for normal and abnormal cases in receiver operating characteristic (ROC) analysis are used to create an ROC curve. The use of established ROC software for the analysis of VGC data has therefore previously been proposed. However, the ROC analysis is based on the assumption of independence between normal and abnormal cases. In VGC analysis, this independence cannot always be assumed, e.g. if the ratings are based on the same patients imaged under both conditions. A dedicated software intended for analysis of VGC studies, which takes possible dependencies between ratings into account in the statistical analysis of a VGC study, has therefore been developed. The software-VGC Analyzer-determines the area under the VGC curve and its uncertainty using non-parametric resampling techniques. This article gives an introduction to VGC Analyzer, describes the types of analyses that can be performed and instructs the user about the input and output data. PMID:26769908

  2. Case study feasibility analysis of the Pelamis wave energy convertor in Ireland, Portugal and North America

    International Nuclear Information System (INIS)

    The performance and economic viability of the Pelamis wave energy converter (WEC) has been investigated over a 20 year project time period using 2007 wave energy data from various global locations: Ireland, Portugal, USA and Canada. Previous reports assessing the Pelamis quote a disparate range of financial returns for the Pelamis, necessitating a comparative standardised assessment of wave energy economic indicators. An Excel model (NAVITAS) was created for this purpose which estimated the annual energy output of Pelamis for each location using wave height (Hs) and period (Tz) data, and produced financial results dependant on various input parameters. The economic indicators used for the analysis were cost of electricity (COE), net present value (NPV) and internal rate of return (IRR), modelled at a tariff rate of EUR0.20/kWh. Analysis of the wave energy data showed that the highest annual energy output (AEO) and capacity for the Pelamis was the Irish site, as expected. Portugal returned lower AOE similar to the lesser North American sites. Monthly energy output was highest in the winter, and was particularly evident in the Irish location. Moreover, the difference between the winter wave energy input and the Pelamis energy output for Ireland was also significant as indicated by the capture width, suggesting that Pelamis design was not efficiently capturing all the wave energy states present during that period. Modelling of COE for the various case study locations showed large variation in returns, depending on the number of WEC modelled and the initial cost input and learning curve. COE was highest when modelling single WEC in comparison to multiples, as well as when using 2004 initial costs in comparison to 2008 costs (at which time price of materials peaked). Ireland returned the lowest COE of EUR0.05/kWh modelling over 100 WEC at 2004 cost of materials, and EUR0.15/kWh at 2008 prices. Although favourable COE were recorded from some of the modelled scenarios

    A high percentage of the division's doctors and employees work at night to guarantee urgent assistance and diagnostic services to patients. Night work is not recommended for persons with rather serious case histories due to the disruption of circadian rhythms or the increased workload required of certain operators during nighttime hours. All of the evaluations of health operators with a limited capacity to work on the night shift in our hospital were analysed, except for female workers restricted from night work during pregnancy or puerperium, as provisioned by the regulation that protects working mothers. Forty-two cases were considered (six physicians and 36 operators in the division) out of a total of 2676 employees assigned to night work and the conditions that led to the formulation of the decision are divided as follows: 16 Mental disturbances currently subject to treatment (depression, post-traumatic anxiety disorder, primary insomnia...), 8 Tumours (breast, colon, Ewing Sarcoma), 7 Neurological disorders (multiple sclerosis, myasthenia), 6 Cardiovascular disease (previous IMA; arrhythmias, arterial hypertension not controlled by theraphy) and 5 others patologies (total 45). The cases will be analysed in detail with an analysis of the characteristics of the exempt group of workers and with reference to the temporary or indefinite nature of the exemption. PMID:23405636

    As per the current estimates, nearly half of the world's population lives in the cities, by 2030 it is calculated to increase to 70%. This calls for a need of more sustainable structure in the urban areas as to support increase in the urban population. Urban Heat Island is one such conspicuous phenomenon which has its significance at local regional and also at the global levels. It is a microscale temperature variation between urban and rural areas, in which urban area are warmer compare to surrounding rural area. The temperature difference between the urban and the rural areas are usually modest, averaging less than 1°C, but occasionally rising to several degrees when urban, topographical and meteorological conditions are favorable for the UHI to develop. It is defined as the phenomena where in the occurrence of surface and atmospheric modifications due to the urbanization causes modification in the thermal climatic conditions which results into warmer areas as compared to the surrounding non urbanized areas, particularly in night. In that case urban built forms such as buildings, roofs, pavements etc. absorb more solar heat/radiation and remain warmer throughout the day time and slowly release energy during night time. The two major causes are rapid urbanization and anthropogenic heat generated due to transport and industrial activities. Urban Heat Island is a crucial subject for global environment. Urbanization has significant effects on local weather and climate. Among these effects one of the most popular is the urban heat island, for which the temperatures of the central urban locations are several degrees higher than those of nearby rural areas of similar elevation. Satellite data provides important inputs for estimating regional surface albedo and evapo-transpiration required in the studies related to surface energy balance. The phenomenon of UHI affects environment and population in so many ways it can also be considered as an active element that cause

    This case study considers two frequently advocated approaches to reducing indirect taxation in Brazil: reduction in taxes on food; reduction in taxes on intermediate inputs to agriculture. To asses the effects of both on income distribution poverty levels, a bottom-up general equilibrium model of Brazil (TERM-BR) is linked to a microsimulation model. It is shown that one of the favoured policies is more poverty reducing, the other more income inequality reducing. Perhaps even more importantly...

    The appropriateness of case studies as a tool for theory testing is still a controversial issue, and discussions about the weaknesses of such research designs have previously taken precedence over those about its strengths. The purpose of the paper is to examine and revive the approach of theory...... testing using case studies, including the associated research goal, analysis, and generalisability. We argue that research designs for theory testing using case studies differ from theorybuilding case study research designs because different research projects serve different purposes and follow different...

  19. Barriers and opportunities in realising sustainable energy concepts--an analysis of two Swiss case studies

    International Nuclear Information System (INIS)

    What assists and what hinders sustainable energy use in being put into effect? Two case studies of sustainable energy concepts--the Zurich Solarstromboerse, where electricity can be purchased that is produced by solar panels, and the Swiss CO2-law, a consensus oriented implementation of the Kyoto-protocol--were analysed in order to investigate this question. In both case studies the unfolding of the sustainable energy concepts is reconstructed as a process starting with an abstract idea moving to a concrete realisation. This process passes through a series of different social worlds and is, in turn, affected by them. These social worlds are e.g. those of the concerned scientists, the professional investors, energy suppliers or governmental agencies. The case studies reveal three neuralgic challenges that have to be met when a concept advances from idea to realisation through the social worlds: Firstly, the translation between social worlds changes the content of the idea. Secondly, the way each social world looks at things (socially) constructs best solutions to problems and hides others. Thirdly, the actual dynamics of the social world within which it is finally implemented must be adopted by the idea. In order to integrate these neuralgic points, scientists as well as other inventors have to retain responsibility for their sustainable energy ideas and are requested to follow them through the social worlds in order to critically survey and eventually influence their 'content in flux'

  4. How Multilevel Societal Learning Processes Facilitate Transformative Change: A Comparative Case Study Analysis on Flood Management

    Directory of Open Access Journals (Sweden)

    Claudia Pahl-Wostl

    2013-12-01

    Full Text Available Sustainable resources management requires a major transformation of existing resource governance and management systems. These have evolved over a long time under an unsustainable management paradigm, e.g., the transformation from the traditionally prevailing technocratic flood protection toward the holistic integrated flood management approach. We analyzed such transformative changes using three case studies in Europe with a long history of severe flooding: the Hungarian Tisza and the German and Dutch Rhine. A framework based on societal learning and on an evolutionary understanding of societal change was applied to identify drivers and barriers for change. Results confirmed the importance of informal learning and actor networks and their connection to formal policy processes. Enhancing a society's capacity to adapt is a long-term process that evolves over decades, and in this case, was punctuated by disastrous flood events that promoted windows of opportunity for change.

    Sam Mavandadi

    Full Text Available In this work we investigate whether the innate visual recognition and learning capabilities of untrained humans can be used in conducting reliable microscopic analysis of biomedical samples toward diagnosis. For this purpose, we designed entertaining digital games that are interfaced with artificial learning and processing back-ends to demonstrate that in the case of binary medical diagnostics decisions (e.g., infected vs. uninfected, with the use of crowd-sourced games it is possible to approach the accuracy of medical experts in making such diagnoses. Specifically, using non-expert gamers we report diagnosis of malaria infected red blood cells with an accuracy that is within 1.25% of the diagnostics decisions made by a trained medical professional.

    2015-12-01

    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

  14. LIDAR data to support coastal erosion analysis: the Conero study case

    2013-04-01

    In the last decades, the topic of coastal erosion and the derived risk have been subject of a growing interest for public authorities and researchers. Recent major natural events, such as hurricanes, tsunamis, and sea level rising, called the attention of media and society, underlining serious concerns about such problems. In a high-density populated country such as Italy, where tourism is one of the major economic activities, the coastal erosion is really a critical issue. In April 2010, along a reach of the coast of Ventotene Island, two young students tragically died, killed by a rock fall. This event dramatically stressed public authorities about the effectiveness of structural and non-structural measures for the mitigation of such phenomena. It is clear that an improving of the actual knowledge about coastal erosion is needed, especially to monitor such events and to set alert systems. In the last few years, airborne LIDAR technology led to a dramatic increase in terrain information. Airborne LiDAR and Terrestrial Laser Scanner (TLS) derived high-resolution Digital Terrain Models (DTMs) have opened avenues for hydrologic and geomorphologic studies (Tarolli et al., 2009). In general, all the main surface processes signatures are correctly recognized using a DTM with cell sizes of 1 m. Having said that, some sub-meter grid sizes may be more suitable in those situations where the analysis of micro topography related to micro changes due to slope failures is critical for risk assessment, and the Terrestrial Laser Scanner (TLS) has been proven to be a useful tool for such detailed field survey. The acquired elevation data with TLS allow to derive a centimeters high quality DTMs. The possibility to detect in detail the slope failures signatures results in a better understanding and mapping of the erosion susceptibility, and of those areas where slope failures are more likely to happen. In addition, these information can be also considered as the basis to develop

    Full Text Available This study identified the essential factors of production in the Tono irrigation dam of the Upper East Region. The accessibility and patronage of these factors by farmers in this area was studied and how they influence crop production in the Region. A total of two hundred questionnaires designed by the Ministry of Food and Agriculture for farmers in Navrongo were administered. A snowball sampling design was employed to identify farmers on these facilities in the study area. Pearson correlation coefficient, principal component analysis, and subset regression analysis were used to unveil the relevant information in the study. The results revealed a high correlation between the factors of production being studied with each pair having a probability level less than 0.0001. The full general linear model was highly significant (F=662.50, psmaller tahn 0.0001 with only two factors (Farm size and Fertilizer accounting for 98.86% of the total variation in yield. This is a clear indication of multicollinearity and a subset regression analysis was used to identify the best subset that improves yield in the irrigation dam. The best subset comprised of Age, Farm size, seed, and Fertilizer accounting for 97.75% of the total variation in crop production in Navrongo. To enhance yield in Navrongo therefore, high yielding seeds, timely granting of fertilizer credit to farmers who mature enough and responsible with reasonable farm sizes should be encouraged.

    2011-11-01

    Full Text Available The aim of this study is to identify and isolate the major causes of delays in underground lateral development at AngloGold Ashanti (AGA, Obuasi Mine, Ghana. It uses fishbone analysis to identify and present 20 possible causes of delays in lateral development at the mine. By employing Pareto analysis, 7 major causes of delays have been isolated. They are: scoop problems, low compressed air, labour shortages, bad ground, flood, power outages and waste pass getting full. The study concludes that, should management concentrate in minimising the 7 major causes of delays, it will be solving about 80% of the problems associated with delays in underground lateral development at AGA, Obuasi mine. The study further gives specific recommendations to reduce delays in lateral development at the mine.

    2012-07-01

    The effects of light pollution problems in metropolitan areas are investigated in this study. Areas of Hong Kong are used as the source of three typical study cases. One case represents the regional scale, a second represents the district scale, and a third represents the street scale. Two light pollution parameters, Night Sky Brightness (NSB) and Street Light Level (SLL), are the focus of the analyses. Light pollution visualization approaches in relation to the different scales include various light pollution maps. They provide straightforward presentations of the light pollution situations in the study areas. The relationship between light pollution and several social-economic factors such as land use, household income, and types of outdoor lighting in the scale areas given, are examined. Results show that: (1) Land use may be one factor affecting light pollution in the regional scale; (2) A relatively strong correlation exists between light pollution and household income in the district scale; (3) The heaviest light pollution in the street scale is created by spotlights and also the different types of lighting from shops. The impact of the latter is in relation to the shop profile and size.

    Highlights: ► We measure and analyze energy request of a food-industry. ► Different sizes of possible to install tri-generation plant are considered. ► Economical and environmental benefits are evaluated by optimization procedure. ► Thermal energy storage is taken into account to improve the benefits. ► Contrast between economic and environmental benefits is remarked in the case study. - Abstract: The application of a trigeneration system to fruit conservation food-industry is studied. The economic and environmental benefits of the installation are analyzed by means of multi-objective optimization which takes into account operational costs of the system and greenhouse gas emissions. A contrast between the minimization of these two objectives is shown and thus different operative strategies are devised. Taken a practical case of the trigeneration load required by an industrial site in north-west of Italy where measurements of load profiles are available, different combined heat and power engines with and without a thermal energy storage system are studied and results are discussed. General considerations about the advantages of the proposed solutions are also presented

    2016-06-01

    Full Text Available Present-day agricultural technology is facing the challenge of limiting the environmental impacts of agricultural production – such as greenhouse gas emissions and demand for additional land – while meeting growing demands for agricultural products. Using the well-established method of life-cycle assessment (LCA, potential environmental impacts of agricultural production chains can be quantified and analyzed. This study presents three case studies of how the method can pinpoint environmental hot spots at different levels of agricultural production systems. The first case study centers on the tractor as the key source of transportation and traction in modern agriculture. A common Austrian tractor model was investigated over its life-cycle, using primary data from a manufacturer and measured load profiles for field work. In all but one of the impact categories studied, potential impacts were dominated by the operation phase of the tractor’s life-cycle (mainly due to diesel fuel consumption, with 84.4-99.6% of total impacts. The production phase (raw materials and final assembly caused between 0.4% and 12.1% of impacts, while disposal of the tractor was below 1.9% in all impact categories. The second case study shifts the focus to an entire production chain for a common biogas feedstock, maize silage. System boundaries incorporate the effect of auxiliary materials such as fertilizer and pesticides manufacturing and application. The operation of machinery in the silage production chain was found to be critical to its environmental impact. For the climate change indicator GWP100 (global warming potential, 100-year reference period, emissions from tractor operation accounted for 15 g CO2-eq per kg silage (64% of total GWP100, followed by field emissions during fertilizer (biogas digestate application with 6 g CO2-eq per kg silage (24% of total GWP100.

    2013-07-01

    We introduce the 3D-segmentation and -visualization software YaDiV to the mineralogical application of rock texture analysis. YaDiV has been originally designed to process medical DICOM datasets. But due to software advancements and additional plugins, this open-source software can now be easily used for the fast quantitative morphological characterization of geological objects from tomographic datasets. In this paper, we give a summary of YaDiV's features and demonstrate the advantages of 3D-stereographic visualization and the accuracy of 3D-segmentation for the analysis of geological samples. For this purpose, we present a virtual and a real use case (here: experimentally crystallized and vesiculated magmatic rocks, corresponding to the composition of the 1991-1995 Unzen eruption, Japan). Especially the spacial representation of structures in YaDiV allows an immediate, intuitive understanding of the 3D-structures, which may not become clear by only looking on 2D-images. We compare our results of object number density calculations with the established classical stereological 3D-correction methods for 2D-images and show that it was possible to achieve a seriously higher quality and accuracy. The methods described in this paper are not dependent on the nature of the object. The fact, that YaDiV is open-source and users with programming skills can create new plugins themselves, may allow this platform to become applicable to a variety of geological scenarios from the analysis of textures in tiny rock samples to the interpretation of global geophysical data, as long as the data are provided in tomographic form.

Higher education and business communication promotion and synergy are being dedicated as a prior target for all EU and EU member countries to be able to continue increasing employment, productivity, as well as social connections. The research of the enterprise and its stimulation in higher education (using higher education and business collaboration is not deep enough, although the enterprise’s multiple phenomenon were analysed from many perspectives. It is being planned to raise EU’s investments to youth much more compared to other main parts of the budget in 2014-2020. Analysis of European Union documents and Lithuanian case studies was chosen on purpose according to the enterprise’s created added value for European development. Realization, creativity, initiative, motivation, taking risks, planning and reaching personal goals are the main parts of the enterprise. Development of these skills in higher education is becoming very important because of “the advantage of the competitiveness is being determined by country‘s social education therefore the effective usage of human recourses is the most important part seeking to increase stabile economical and social well being.” Research of the EU’s and Lithuania’s national documentation and scientific literature review of entrepreneurship in higher education identifies the current enterprise position in education. According to the analyses of the documentation and the scientific literature review, the enterprise’s evaluation level was appointed. The new beginning of the enterprise in higher education is being started after the research was done and centrepiece’s promotion was critically evaluated in the EU and Lithuania.

    Full Text Available In this paper, we address the topic of user-centered design (UCD for cartography, GIScience, and visual analytics. Interactive maps are ubiquitous in modern society, yet they often fail to “work” as they could or should. UCD describes the process of ensuring interface success—map-based or otherwise—by gathering input and feedback from target users throughout the design and development of the interface. We contribute to the expanding literature on UCD for interactive maps in two ways. First, we synthesize core concepts on UCD from cartography and related fields, as well as offer new ideas, in order to organize existing frameworks and recommendations regarding the UCD of interactive maps. Second, we report on a case study UCD process for GeoVISTA CrimeViz, an interactive and web-based mapping application supporting visual analytics of criminal activity in space and time. The GeoVISTA CrimeViz concept and interface were improved iteratively by working through a series of user→utility→usability loops in which target users provided input and feedback on needs and designs (user, prompting revisions to the conceptualization and functional requirements of the interface (utility, and ultimately leading to new mockups and prototypes of the interface (usability for additional evaluation by target users (user… and so on. Together, the background review and case study offer guidance for applying UCD to interactive mapping projects, and demonstrate the benefit of including target users throughout design and development.

    More and more, people are looking to build and live in different ways. They want houses with a high standard of living and reasonable production and maintenance costs. However, they also want to build a way that does not adversely affect their quality of life. Currently, the using of modern methods of construction (MMC) expands consistently year on year. MMC include prefabricated products made in the factory and also new methods of building that are site-based and they are regarded as a means of achieving higher quality, reducing time spent onsite, increasing safety and overcoming skills shortages in the industry. Aim of this paper is to analyze and compare, trough case study, technical, cost and technological parameters of house built by modern method of construction (from insulating concrete formwork) and by traditional method (from brick system). The subject of case study is house modeled in two variants of insulating concrete formwork and a variant bricks and ceiling system. In conclusion, there is selected optimal method and system for house construction through multicriteria optimization.

    The fractal dimension is a significant geophysical parameter describing natural surfaces representing the distribution of the roughness over different spatial scale; in case of volcanic structures, it has been related to the specific nature of materials and to the effects of active geodynamic processes. In this work, we present the analysis of the temporal behavior of the fractal dimension estimates generated from multi-pass SAR images relevant to the Somma-Vesuvio volcanic complex (South Italy). To this aim, we consider a Cosmo-SkyMed data-set of 42 stripmap images acquired from ascending orbits between October 2009 and December 2012. Starting from these images, we generate a three-dimensional stack composed by the corresponding fractal maps (ordered according to the acquisition dates), after a proper co-registration. The time-series of the pixel-by-pixel estimated fractal dimension values show that, over invariant natural areas, the fractal dimension values do not reveal significant changes; on the contrary, over urban areas, it correctly assumes values outside the natural surfaces fractality range and show strong fluctuations. As a final result of our analysis, we generate a fractal map that includes only the areas where the fractal dimension is considered reliable and stable (i.e., whose standard deviation computed over the time series is reasonably small). The so-obtained fractal dimension map is then used to identify areas that are homogeneous from a fractal viewpoint. Indeed, the analysis of this map reveals the presence of two distinctive landscape units corresponding to the Mt. Vesuvio and Gran Cono. The comparison with the (simplified) geological map clearly shows the presence in these two areas of volcanic products of different age. The presented fractal dimension map analysis demonstrates the ability to get a figure about the evolution degree of the monitored volcanic edifice and can be profitably extended in the future to other volcanic systems with

    Inclined topographies are one of the most challenging problems for geospatial analysis of air-borne and space-borne imageries. However, flat areas are mostly misleading to exhibit the real performance. For this reason, researchers generally require a study area which includes mountainous topography and various land cover and land use types. Zonguldak and its vicinity is a very suitable test site for performance investigation of remote sensing systems due to the fact that it contains different land use types such as dense forest, river, sea, urban area; different structures such as open pit mining operations, thermal power plant; and its mountainous structure. In this paper, we reviewed more than 120 proceeding papers and journal articles about geospatial analysis that are performed on the test field of Zonguldak and its surroundings. Geospatial analysis performed with imageries include elimination of systematic geometric errors, 2/3D georeferencing accuracy assessment, DEM and DSM generation and validation, ortho-image production, evaluation of information content, image classification, automatic feature extraction and object recognition, pan-sharpening, land use and land cover change analysis and deformation monitoring. In these applications many optical satellite images are used i.e. ASTER, Bilsat-1, IKONOS, IRS-1C, KOMPSAT-1, KVR-1000, Landsat-3-5-7, Orbview-3, QuickBird, Pleiades, SPOT-5, TK-350, RADARSAT-1, WorldView-1-2; as well as radar data i.e. JERS-1, Envisat ASAR, TerraSAR-X, ALOS PALSAR and SRTM.

    Morphometric analysis is significant for investigation and management of the watershed. This study depicts the morphometric analysis of Miniwada Watershed in Nagpur district, Maharashtra, Central India using Geographic Information System (GIS) techniques, which has been carried out through measurement of various aspects like linear, aerial and relief aspects of watershed. The drainage network of the watershed was generated from Cartosat-I DEM (10 m) using ESRI Software ArcGIS (ver.10.2). The analysis reveals that drainage pattern is dendritic and the stream order in the watershed varies from 1 to 4. The total number of stream segments of all orders counted as 37, out of which the majority of orders (70.27 %) was covered by 1st order streams and 4th order stream segments covers only 2.70 %. The bifurcation ratio reflects the geological and tectonic characteristics of the watershed and estimated as 3.08. The drainage density of the watershed is 3.63 km/sq km and it indicates the closeness of spacing of channels. The systematic analysis of various parameters in GIS helps in better understanding the soil resources distribution, watersheds prioritization, planning and management.

    Full Text Available BACKGROUND: Meta-analysis is a statistical tool for combining and integrating the results of independent studies of a given scientific issue. The present investigation was initiated to investigate case-referent studies of lung cancer risk from specific environmental and occupational pollutants, using detailed individual exposure data. MATERIALS AND METHODS: To examine the risk of lung cancer associated with environmental and occupational pollutants, a meta-analysis of published case-control studies was undertaken using a random effects model. For this study, the papers were selected for review from electronic search of PubMed, Medline and Google Scholar during 1990-2006. The principal outcome measure was the odds ratio for the risk of lung cancer. Twelve study reports detailing the relationship between the lung cancer and the type of exposure were identified. RESULTS: The odds ratio of asbestos, cooking fuel, cooking fumes, motor and diesel exhaust related to lung cancer were 1.67, 1.99, 2.52 and 1.42 ( P < 0.001, respectively. The odds ratio of metal fumes related to lung cancer was 1.28 (0.001 P < 0.01. The combined odds ratio for the environmental and occupational exposure related to lung cancer was 1.67 ( P < 0.001. CONCLUSIONS: The meta-analysis of the present study shows the magnitude association between asbestos, cooking fumes, cooking fuels, motor and diesel exhaust, with lung cancer risk. Lung cancer risk may be reduced by controlling exposure levels.

    The automotive assembly plant in a manufacturing environment consists of conveying systems and robots. Robots with high reliability will ensure no interruption during production. This study is to analyze the individual robot reliability compared to reliability of robots subsystem in series configuration. Availability was computed based on individual robots breakdown data. Failures due to robots breakdown often occurred during the operations. Actual maintenance data for a period of seven years were used for the analysis. Incorporation of failures rate and mean time between failures yield the reliability computation with the assumption of constant failure rate. Result from the analysis based on 5000 operating hours indicated reliability of series configuration of robots in a subsystem decreased to 2.8% in comparison to 38% reliability of the individual robot with the lowest reliability. The calculated lowest availability of the robots is 99.41%. The robot with the lowest reliability and availability should be considered for replacement.

    2011-10-01

    Wind erosion climatic erosivity is a measure of the climatic tendency to produce conditions conducive to wind erosion. This research develops a method to determine the regional climate's tendency to cause wind erosion on the basis of a physically based climatic factor (CE) and linear moment analysis (L-moments) in Fars province, southwest Iran. CE is calculable from wind speed quantiles and other available meteorological data. The wind quantiles can be estimated by a frequency analysis of the available wind data. Wind speed data are often either not available or are of short record length, and thus, CE estimates from such data have large standard errors. In such a situation, data from several sites can be used to estimate wind speed quantiles at each site based on a regional frequency analysis. Monthly averages of maximum daily wind speed of 19 meteorological stations in Fars province were used for regional analysis. Based on L-moment analysis, two homogeneous regions were determined. Regional wind speed quantiles were calculated, and the results were used to calculate CE values for two 6-month wet and dry periods for each homogeneous region. Furthermore, CE values were estimated for each station in the study area using a Weibull distribution, and the results were compared with the regional-based CE values. It showed that CE values estimated using the regional-based approach have smaller sampling variance compared to those obtained from the Weibull method. The proposed method can be used to evaluate the regional risk of wind erosion in arid and semi-arid environments.

    Full Text Available OBJECTIVE: To analyze the frequency and prevalence of congenital heart defects in a tertiary care center for children with heart diseases. METHODS: We carried out an epidemiological assessment of the first medical visit of 4,538 children in a pediatric hospital from January 1995 to December 1997. All patients with congenital heart defects had their diagnoses confirmed at least on echocardiography. The frequency and prevalence of the anomalies were computed according to the classification of sequential analysis. Age, weight, and sex were compared between the groups of healthy individuals and those with congenital heart defects after distribution according to the age group. RESULTS: Of all the children assessed, 2,017 (44.4% were diagnosed with congenital heart disease, 201 (4.4% with acquired heart disease, 52 (1.2% with arrhythmias, and 2,268 (50% were healthy children. Congenital heart diseases predominated in neonates and infants, corresponding to 71.5% of the cases. Weight and age were significantly lower in children with congenital heart defects. Ventricular septal defect was the most frequent acyanotic anomaly, and tetralogy of Fallot was the most frequent cyanotic anomaly. CONCLUSION: Children with congenital heart defects are mainly referred during the neonatal period and infancy with impairment in gaining weight. Ventricular septal defect is the most frequent heart defect.

  12. A case study for large-scale human microbiome analysis using JCVI's metagenomics reports (METAREP.

    Directory of Open Access Journals (Sweden)

    Johannes Goll

    Full Text Available As metagenomic studies continue to increase in their number, sequence volume and complexity, the scalability of biological analysis frameworks has become a rate-limiting factor to meaningful data interpretation. To address this issue, we have developed JCVI Metagenomics Reports (METAREP as an open source tool to query, browse, and compare extremely large volumes of metagenomic annotations. Here we present improvements to this software including the implementation of a dynamic weighting of taxonomic and functional annotation, support for distributed searches, advanced clustering routines, and integration of additional annotation input formats. The utility of these improvements to data interpretation are demonstrated through the application of multiple comparative analysis strategies to shotgun metagenomic data produced by the National Institutes of Health Roadmap for Biomedical Research Human Microbiome Project (HMP (http://nihroadmap.nih.gov. Specifically, the scalability of the dynamic weighting feature is evaluated and established by its application to the analysis of over 400 million weighted gene annotations derived from 14 billion short reads as predicted by the HMP Unified Metabolic Analysis Network (HUMAnN pipeline. Further, the capacity of METAREP to facilitate the identification and simultaneous comparison of taxonomic and functional annotations including biological pathway and individual enzyme abundances from hundreds of community samples is demonstrated by providing scenarios that describe how these data can be mined to answer biological questions related to the human microbiome. These strategies provide users with a reference of how to conduct similar large-scale metagenomic analyses using METAREP with their own sequence data, while in this study they reveal insights into the nature and extent of variation in taxonomic and functional profiles across body habitats and individuals.

The influence of impoundment liners, native soil, and rock types, as well as groundwater are discussed. Selected case studies of applications are reported and discussed

  14. Tornado missile risk analysis: probability modeling, simulation methodology, and case studies. Final report

    International Nuclear Information System (INIS)

    Mathematical models of the contributing events to the tornado missile hazard at nuclear power plants have been developed in which the major sources of uncertainty have been considered in a probabilistic framework. These models have been structured into a sequential event formalism which permits the treatment of both single and multiple missile generation events. A simulation computer code utilizing these models has been developed to obtain estimates of tornado missile event likelihoods. Two case studies have been analyzed: a single unit plant using the current NRC set of missiles and a two unit arrangement using an expanded missile set. Preliminary results suggest that the likelihood of missile strike and that of subsequent plant damage may be acceptably small

    2009-06-01

    This paper describes the use of oxygen (18O) isotope analysis of water contained in two different materials--beer and diesel fuel--involved in the resolution of two separate cases. In the first case study, it was possible to demonstrate that a sample of beer labelled as premium brand in fact belonged to a cheap brand. The second case related to the contamination of diesel fuel from a service station. The diesel fuel contained visible amounts of water, which caused vehicles that had been filled up with it to become defective. For insurance purposes, it was necessary to determine the source of water. The delta18O values for the water of nearly all samples of diesel was close to the delta18O of local tap water at the filling station. PMID:19606593

    Multihazard risk analysis and disaster planning for emergency services as a basis for efficient provision in the case of natural hazards - case study municipality of Au, Austria A. Maltzkait (1) & C. Pfurtscheller (1) (1) Institute for Interdisciplinary Mountain Research (IGF), Austrian Academy of Sciences, Innsbruck, Austria The extreme flood events of 2002, 2005 and 2013 in Austria underlined the importance of local emergency services being able to withstand and reduce the adverse impacts of natural hazards. Although for legal reasons municipal emergency and crisis management plans exist in Austria, they mostly do not cover risk analyses of natural hazards - a sound, comparable assessment to identify and evaluate risks. Moreover, total losses and operational emergencies triggered by natural hazards have increased in recent decades. Given sparse public funds, objective budget decisions are needed to ensure the efficient provision of operating resources, like personnel, vehicles and equipment in the case of natural hazards. We present a case study of the municipality of Au, Austria, which was hardly affected during the 2005 floods. Our approach is primarily based on a qualitative risk analysis, combining existing hazard plans, GIS data, field mapping and data on operational efforts of the fire departments. The risk analysis includes a map of phenomena discussed in a workshop with local experts and a list of risks as well as a risk matrix prepared at that workshop. On the basis for the exact requirements for technical and non-technical mitigation measures for each natural hazard risk were analysed in close collaboration with members of the municipal operation control and members of the local emergency services (fire brigade, Red Cross). The measures includes warning, evacuation and, technical interventions with heavy equipment and personnel. These results are used, first, to improve the municipal emergency and crisis management plan by providing a risk map, and a

    Yanjiao Zhou

    Full Text Available Necrotizing enterocolitis (NEC is an inflammatory disease of the newborn bowel, primarily affecting premature infants. Early intestinal colonization has been implicated in the pathogenesis of NEC. The objective of this prospective case-control study was to evaluate differences in the intestinal microbiota between infants who developed NEC and unaffected controls prior to disease onset. We conducted longitudinal analysis of the 16S rRNA genes of 312 samples obtained from 12 NEC cases and 26 age-matched controls with a median frequency of 7 samples per subject and median sampling interval of 3 days. We found that the microbiome undergoes dynamic development during the first two months of life with day of life being the major factor contributing to the colonization process. Depending on when the infant was diagnosed with NEC (i.e. early vs. late onset, the pattern of microbial progression was different for cases and controls. The difference in the microbiota was most overt in early onset NEC cases and controls. In proximity to NEC onset, the abundances of Clostridium sensu stricto from Clostridia class were significantly higher in early onset NEC subjects comparing to controls. In late onset NEC, Escherichia/Shigella among Gammaproteobacteria, showed an increasing pattern prior to disease onset, and was significantly higher in cases than controls six days before NEC onset. Cronobacter from Gammaproteobacteria was also significantly higher in late onset NEC cases than controls 1-3 days prior to NEC onset. Thus, the specific infectious agent associated with NEC may vary by the age of infant at disease onset. We found that intravenously administered antibiotics may have an impact on the microbial diversity present in fecal material. Longitudinal analysis at multiple time points was an important strategy utilized in this study, allowing us to appreciate the dynamics of the premature infant intestinal microbiome while approaching NEC at various points.

    This article presents a method to incorporate and promote quantitative risk analysis to support local action planning against flooding. The proposed approach aims to provide a framework for local flood risk analysis, combining hazard mapping with vulnerability data to quantify risk in terms of expected annual affected population, potential injuries, number of fatalities, and economic damages. Flood risk is estimated combining GIS data of loads, system response, and consequences and using event tree modelling for risk calculation. The study area is the city of Oliva, located on the eastern coast of Spain. Results from risk modelling have been used to inform local action planning and to assess the benefits of structural and non-structural risk reduction measures. Results show the potential impact on risk reduction of flood defences and improved warning communication schemes through local action planning: societal flood risk (in terms of annual expected affected population) would be reduced up to 51 % by combining both structural and non-structural measures. In addition, the effect of seasonal population variability is analysed (annual expected affected population ranges from 82 to 107 %, compared with the current situation, depending on occupancy rates in hotels and campsites). Results highlight the need for robust and standardized methods for urban flood risk analysis replicability at regional and national scale.

    Mid-scale regional ecosecurity, which takes practical ecosecurity issues as its priority, should be viewed as the core of the multi-scale concept of ecosecurity. For urban area, a special region taking ecological infrastructure as its core mission, the construction of regional ecosecurity pattern may provide a good chance to realize its sustainable development. Based on land use analysis, a qualitative and quantitative research on the landscape pattern, ecovalue evaluation, and driving force analysis of social economy could provide an effective approach to construct the ecosecurity pattern in urban area. This study showed that in Lanzhou, the ecosecurity pattern consisted of three parts, i.e., eco-safeguarding system, eco-buffering system and eco-percolating system, among which, eco-buffering system was the decisive part determining ecosecurity pattern construction. The quantitative analysis of urban spatial expansion pattern was taken as the decisive function to determine the security level of the ecosecurity pattern, which was divided into low, middle and high levels.

    2015-06-01

    Full Text Available The correlation of urban metabolism and changes in land use is an important issue in urban ecology, but recent research lacks consideration of the mechanisms and interactions between them. In this research, we did an emergy analysis of the flows of materials, energy, and capital within the socioeconomic system of Beijing. We calculated emergy-based evaluation indices of urban metabolism and land use change, to analyze the relationship between urban metabolism and land use by correlation analysis and regression analysis. Results indicate that the socio-economic activities on built-up land depend on local, non-renewable resource exploitation and external resource inputs. The emergy utilization efficiency of farmland has consistently decreased, but there remains significant utilization potential there. Urban development in Beijing relies on production activities on built-up land, which is subjected to great environmental pressure during extraction of material resources. To keep the economy developing effectively, we suggest that Beijing should commit to development of a circular economy, and change the land-use concept to “Smart Growth”. In this paper, we efficaciously solve the problem of conflicting measurement units, and avoid the disadvantages of subjective assignment. Consequently, this work provides not only a more scientific way to study land problems, but also provides a reliable reference for ecological construction and economic development in Beijing.

    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.

    2009-01-01

    Recent research has shown that language and the socio-cognitive phenomena associated with it can be aptly modeled and visualized through networks of linguistic entities. However, most of the existing works on linguistic networks focus only on the local properties of the networks. This study is an attempt to analyze the structure of languages via a purely structural technique, namely spectral analysis, which is ideally suited for discovering the global correlations in a network. Application of this technique to PhoNet, the co-occurrence network of consonants, not only reveals several natural linguistic principles governing the structure of the consonant inventories, but is also able to quantify their relative importance. We believe that this powerful technique can be successfully applied, in general, to study the structure of natural languages.

    2008-01-01

    The method "Material Flow Analysis (MFA)" is one of the effective tools to study law and quantification of material flow between economic system and ecological system. On the national level, economy-wide material flow analysis has been published for a number of countries. However, published studies on the regional or local level are still very limited and a standardized method does not exist yet. On the basis of framework of Material Flow Analysis proposed by Eurostat, the paper collected related data and analyzed material input and output for the Chengyang district in Qingdao. The results showed that DMI (Direct Material Input) and TMR (Total Material Requirement) in absolute number increased about 3.6 and 3.9 times, respectively from 1995 to 2004. Fossil fuel and mineral contributed to about 50.3%-76.3% of DMI. Imports of material increased about 5.0 times and became the most important contributor to DMI, which showed that local economic growth was highly dependent on resources from other regions and countries. DPO (Domestic Processed Output) and TDO (Total Domestic Output) represent slow increasing trend, and DPO contributed to 22.2%-58.1% of TDO, suggesting local hidden flows were of obvious effect on TDO. The biggest component of DPO is CO2, approximately accounting for 90% of DPO. The material productivity increased 57.7% in last decade, reflecting improvement of efficiency of resources utilization in some extent. However, compared to developed countries and regions, material productivity of Chengyang district was relatively low.Therefore, in order to promote the sustainability, it is essential to develop circular economy and enhance materials productivity.

  14. An analysis of uranium dispersal and health effects using a Gulf War case study.

    Marshall, Albert Christian

    2005-07-01

    The study described in this report used mathematical modeling to estimate health risks from exposure to depleted uranium (DU) during the 1991 Gulf War for both U.S. troops and nearby Iraqi civilians. The analysis found that the risks of DU-induced leukemia or birth defects are far too small to result in an observable increase in these health effects among exposed veterans or Iraqi civilians. Only a few veterans in vehicles accidentally struck by U.S. DU munitions are predicted to have inhaled sufficient quantities of DU particulate to incur any significant health risk (i.e., the possibility of temporary kidney damage from the chemical toxicity of uranium and about a 1% chance of fatal lung cancer). The health risk to all downwind civilians is predicted to be extremely small. Recommendations for monitoring are made for certain exposed groups. Although the study found fairly large calculational uncertainties, the models developed and used are generally valid. The analysis was also used to assess potential uranium health hazards for workers in the weapons complex. No illnesses are projected for uranium workers following standard guidelines; nonetheless, some research suggests that more conservative guidelines should be considered.

The results show that immigration has influenced the spatial distribution of social groups and physical development of Alvand city.

  16. Nuclear terrorism risk analysis using game theory. Case study of sea transportation of MOX fuel

    International Nuclear Information System (INIS)

    While considerable attention and resources have been directed towards improving nuclear security in Japan in response to the threat of nuclear terrorism, the transport of nuclear material raises concern by the public as indicated in the recent return of MOX fuel from Europe. This concern cannot be adequately addressed by the government through communications with the public because of the confidential nature of such transport. Also, it remains a challenge for adequately assessing the nuclear terrorism risk because many key parameters associated with such assessment cannot be derived from statistical data and reflect actors' intentions unlike assessment on natural disasters. This study proposes an assessment methodology which introduces game theory to deduce the correlations between those key parameters and can be used to analyze the nuclear terrorism risk, both quantitatively and qualitatively for the civilian use of nuclear power. Risk will be calculated by Monte Carlo methods based on probability distributions set for actors' utilities. A case-study of transporting the MOX fuel by sea is also included. (author)

    The draft legislation on e-waste prepared by the Chinese national government assigns management responsibility to local governments. It is an urgent task for the municipal government to plan an effective system as soon as possible to divert the e-waste flow from the existing informal e-waste recycling processes. This paper presents a case study implemented in Beijing, the capital city of China, with the purpose of predicting the amount of obsolete equipment for five main kinds of electronic appliances from urban households and to analyse the flow after the end of their useful phase. The amount to be handled was 885,354 units in 2005 and is predicted to double by 2010. Due to consumption growth and the expansion of urbanization it is estimated that the amount will increase to approximate 2,820,000 units by 2020: 70% of the obsolete appliances will be awaiting collection for possible recycling, 7% will be stored at the owner's home for 1 year on average and 4% will be discarded directly and enter the municipal solid waste collecting system. The remaining items will be reused for about 3 years on average after the change of ownership. The results of this study will assist the waste management authorities of Beijing to plan the collecting system and facilities needed for management of e-waste generated in the near future.

    We investigated chemical and microphysical processes in the late winter in the Antarctic lower stratosphere, after the first chlorine activation and initial ozone depletion. We focused on a time interval when both further chlorine activation and ozone loss, but also chlorine deactivation, occur. We performed a comprehensive Lagrangian analysis to simulate the evolution of an air mass along a 10-day trajectory, coupling a detailed microphysical box model to a chemistry model. Model results have been compared with in situ and remote sensing measurements of particles and ozone at the start and end points of the trajectory, and satellite measurements of key chemical species and clouds along it. Different model runs have been performed to understand the relative role of solid and liquid polar stratospheric cloud (PSC) particles for the heterogeneous chemistry, and for the denitrification caused by particle sedimentation. According to model results, under the conditions investigated, ozone depletion is not affected significantly by the presence of nitric acid trihydrate (NAT) particles, as the observed depletion rate can equally well be reproduced by heterogeneous chemistry on cold liquid aerosol, with a surface area density close to background values. Under the conditions investigated, the impact of denitrification is important for the abundances of chlorine reservoirs after PSC evaporation, thus stressing the need to use appropriate microphysical models in the simulation of chlorine deactivation. We found that the effect of particle sedimentation and denitrification on the amount of ozone depletion is rather small in the case investigated. In the first part of the analyzed period, when a PSC was present in the air mass, sedimentation led to a smaller available particle surface area and less chlorine activation, and thus less ozone depletion. After the PSC evaporation, in the last 3 days of the simulation, denitrification increases ozone loss by hampering chlorine

  20. Using Analysis of Governance to Unpack Community-Based Conservation: A Case Study from Tanzania

    Robinson, Lance W.; Makupa, Enock

    2015-11-01

    Community-based conservation policies and programs are often hollow with little real devolution. But to pass a judgment of community-based or not community-based on such initiatives and programs obscures what is actually a suite of attributes. In this paper, we analyze governance around a specific case of what is nominally community-based conservation—Ikona Wildlife Management Area (WMA) in Tanzania—using two complementary sets of criteria. The first relates to governance "powers": planning powers, regulatory powers, spending powers, revenue-generating powers, and the power to enter into agreements. The second set of criteria derive from the understanding of governance as a set of social functions: social coordination, shaping power, setting direction, and building community. The analysis helps to detail ways in which the Tanzanian state through policy and regulations has constrained the potential for Ikona WMA to empower communities and community actors. Although it has some features of community-based conservation, community input into how the governance social functions would be carried out in the WMA was constrained from the start and is now largely out of community hands. The two governance powers that have any significant community-based flavor—spending powers and revenue-generating powers—relate to the WMA's tourism activities, but even here the picture is equivocal at best. The unpacking of governance that we have done, however, reveals that community empowerment through the processes associated with creating and recognizing indigenous and community-conserved areas is something that can be pursued through multiple channels, some of which might be more strategic than others.

    Early-age cracking can adversely affect strength, serviceability, and durability of concrete bridge decks. Early age is defined as the period after final setting, during which concrete properties change rapidly. Many factors can cause early-age bridge deck cracking including temperature change, hydration, plastic shrinkage, autogenous shrinkage, and drying shrinkage. The cracking may also increase the effect of freeze and thaw cycles and may lead to corrosion of reinforcement. This research paper presents an analysis of causes and factors affecting early-age cracking. It also provides a tool developed to predict the likelihood and initiation of early-age cracking of concrete bridge decks. Understanding the concrete properties is essential so that the developed tool can accurately model the mechanisms contributing to the cracking of concrete bridge decks. The user interface of the implemented computer Excel program enables the user to input the properties of the concrete being monitored. The research study and the developed spreadsheet were used to comprehensively investigate the issue of concrete deck cracking. The spreadsheet is designed to be a user-friendly calculation tool for concrete mixture proportioning, temperature prediction, thermal analysis, and tensile cracking prediction. The study also provides review and makes recommendations on the deck cracking based mainly on the Florida Department of Transportation specifications and Structures Design Guidelines, and Bridge Design Manuals of other states. The results were also compared with that of other commercially available software programs that predict early-age cracking in concrete slabs, concrete pavement, and reinforced concrete bridge decks. The outcome of this study can identify a set of recommendations to limit the deck cracking problem and maintain a longer service life of bridges.

    Early-age cracking can adversely affect strength, serviceability, and durability of concrete bridge decks. Early age is defined as the period after final setting, during which concrete properties change rapidly. Many factors can cause early-age bridge deck cracking including temperature change, hydration, plastic shrinkage, autogenous shrinkage, and drying shrinkage. The cracking may also increase the effect of freeze and thaw cycles and may lead to corrosion of reinforcement. This research paper presents an analysis of causes and factors affecting early-age cracking. It also provides a tool developed to predict the likelihood and initiation of early-age cracking of concrete bridge decks. Understanding the concrete properties is essential so that the developed tool can accurately model the mechanisms contributing to the cracking of concrete bridge decks. The user interface of the implemented computer Excel program enables the user to input the properties of the concrete being monitored. The research study and the developed spreadsheet were used to comprehensively investigate the issue of concrete deck cracking. The spreadsheet is designed to be a user-friendly calculation tool for concrete mixture proportioning, temperature prediction, thermal analysis, and tensile cracking prediction. The study also provides review and makes recommendations on the deck cracking based mainly on the Florida Department of Transportation specifications and Structures Design Guidelines, and Bridge Design Manuals of other states.

  4. Innovation in emerging energy technologies: A case study analysis to inform the path forward for algal biofuels

    International Nuclear Information System (INIS)

    Algal biofuel is an emerging energy source that has the potential to improve upon the environmental benefits realized by conventional biofuels and contribute to the biofuels mandate set by the Renewable Fuel Standard (RFS). While there has been much research into producing fuel from algae, a commercial-scale facility has not yet been built. We examine two case studies of energy technology innovation in the United States, first generation biodiesel and solar photovoltaics (PV), using the technological innovation system (TIS) framework to provide lessons and inform the path forward for commercializing algal biofuel. We identify five event types that have been the most influential to these innovation processes: changing expectations, technology development, demonstration projects, policy targets, and government subsidies. Some algal biofuel demonstration projects have occurred, but despite falling under the mandates set forth in the RFS (a policy target), algal biofuels do not currently receive production subsidies. The main finding from the case study analysis is that government interventions have significantly influenced the innovation processes of first generation biodiesel and solar PV and will likely be key factors in the commercialization of algal biofuel. - Highlights: • Two energy technology case studies were analyzed with a TIS framework. • Major drivers in the innovation process were identified in each case. • Government interventions were key factors for both. • The one identified key driver algal biofuel is lacking is federal subsidies. • All components of the TIS framework deserve attention in promoting innovation

    Protein structural alignments are generally considered as ‘golden standard’ for the alignment at the level of amino acid residues. In this study we have compared the quality of pairwise and multiple structural alignments of about 5900 homologous proteins from 718 families of known 3-D structures. We observe shifts in the alignment of regular secondary structural elements (helices and strands) between pairwise and multiple structural alignments. The differences between pairwise and multiple structural alignments within helical and -strand regions often correspond to 4 and 2 residue positions respectively. Such shifts correspond approximately to “one turn” of these regular secondary structures. We have performed manual analysis explicitly on the family of protein kinases. We note shifts of one or two turns in helix-helix alignments obtained using pairwise and multiple structural alignments. Investigations on the quality of the equivalent helix-helix, strand-strand pairs in terms of their residue side-chain accessibilities have been made. Our results indicate that the quality of the pairwise alignments is comparable to that of the multiple structural alignments and, in fact, is often better. We propose that pairwise alignment of protein structures should also be used in formulation of methods for structure prediction and evolutionary analysis.

    A quantitative analysis of torrential rainfall associated with typhoon Haitang (2005) is carried out using a modified moist ageostrophic Q vector and data from Weather Research and Forecasting (WRF) model simulation.Four major factors determining the ascending motion associated with torrential rainfall have been studied:large-scale and convective condensational heating,topographic lifting and friction.The results show that the convective condensational heating plays a major role in the torrential rainfall process,and the large-scale condensational heating is secondary before the landfall of typhoon Haitang,and vice versa after the landfall.The topographic lifting affects the formation of rainfall,whereas the topographic friction has important impacts on torrential rainfall after the landfall.The rainfall amounts forced by the topographic friction and lifting have similar horizontal distributions,but the magnitudes of the former are 2-3 times larger than those of the latter.The rainfall amounts forced by topography (lifting and friction) and modified moist ageostrophic Q vector have different horizontal distributions,and the magnitudes of the former are 2-5 times larger than those of the latter.Synthetic analysis shows that the typhoon rainfall may be motivated by modified moist ageostrophic Q vector and enhanced further by the topographic effects.

    The pulp and paper industry is a significant consumer of fossil energy in the Taiwanese manufacturing sector. The concentration of greenhouse gases (GHG) from manufacturing factory activities and vehicle emissions has increased remarkably. Notable energy savings can be achieved in the pulp and paper industry through energy flow analysis. The aim of this paper is to analyze the energy flow for three major energy consuming mills of the pulp and paper industry in Taiwan to make energy savings. In addition, potential technology options are examined for the capture of some of the energy that is currently lost in the processes and to identify the areas of energy saving potential that could have a large impact across more than one industry. The results of this study can serve as a benchmark for developing a quantified list in terms of energy savings potential and opportunities for improving the efficiency of the pulp and paper industry. - Highlights: ► The aim of this paper was to analyze the energy flow for three pulps and paper firms in Taiwan. ► The results were used as the basis for developing a quantified list in terms of energy savings potential. ► Energy flow analysis results can serve as benchmarks for the current pulp and paper making operations.

  10. Energy use and economical analysis of potato production in Iran a case study: Ardabil province

    International Nuclear Information System (INIS)

    The purpose of this study is to determine energy consumption of input and output used in potato production, and making an economical analysis in Ardabil, Iran. For this purpose, the data were collected from 100 potato farms in Ardabil, Iran. Inquiries were conducted in a face-to-face interviewing November-December 2006 period. Farms were selected based on random sampling method. The results indicated that total energy inputs were 81624.96 MJ ha-1. About 40% of this was generated by chemical fertilizers, 20% from diesel oil and machinery. About 82% of the total energy inputs used in potato production was indirect (seeds, fertilizers, manure, chemicals, machinery) and 18% was direct (human labor, diesel). Mean potato yield was about 28453.61 kg ha-1, it obtained under normal conditions on irrigated farming, and taking into account the energy value of the seed, the net energy and energy productivity value was estimated to be 20808.03 MJ ha-1 and 0.35, respectively, and the ratio of energy outputs to energy inputs was found to be 1.25. This indicated an intensive use of inputs in potato production not accompanied by increase in the final product. Cost analysis revealed that total cost of production for one hectare of potato production was 3267.17 $. Benefit-cost ratio was calculated as 1.88

    The role and the functions of rural areas are undergoing considerable change due to economic, social and environmental drivers. The outcome of the transformation is the production of highly heterogeneous landscapes, rural mosaics, which are home to varying degrees of intensity of land-use and processes of deactivation, abandonment and land degradation. The identification of rural mosaics has implications both for determining the impacts on the stock of connected natural resources and for defining measures and policies able to support the resilience of rural territories and the identification of sustainable strategies for development. The study proposes a methodology for the integrated analysis of the rural territory which combines the analysis of land cover dynamics, using GIS, with an assessment of socio-economic dynamics, reconstructed through the combined use of indicators and local history, and which is aware that the differences and peculiarities within rural territories are the result of actions taken over time and of the different adaptive strategies undertaken by communities operating in different fields, under the influence of specific ecologic and environmental conditions. The methodology, applied to a socio-ecological system which is representative of the Mediterranean basin, is proposed as a tool to support the territorialisation of polices, opening the process up to perspectives able to better comprehend the dynamic evolution of rural territories, internalising that evolution in the definition of the instruments and measures to adopt.

    Full Text Available Background   Globally, diabetes mellitus presents a substantial burden to individuals and healthcare systems. Structuring and/or coding of medical records underpin attempts to improve information sharing and searching, potentially bringing clinical and secondary uses benefits.Aims and objectives   We investigated if, how and why records for adults with diabetes were structured and/or coded, and explored stakeholders’ perceptions of current practice.Methods   We carried out a qualitative, theoretically-informed case study of documenting healthcare information for diabetes patients in family practice and hospital settings, using semi-structured interviews, observations, systems demonstrations and documentary data.Results   We conducted 22 interviews and four on-site observations, and reviewed 25 documents. For secondary uses – research, audit, public health and service planning – the benefits of highly structured and coded diabetes data were clearly articulated. Reported clinical benefits in terms of managing and monitoring diabetes, and perhaps encouraging patient self-management, were modest. We observed marked differences in levels of record structuring and/or coding between settings, and found little evidence that these data were being exploited to improve information sharing between them.Conclusions   Using high levels of data structuring and coding in medical records for diabetes patients has potential to be exploited more fully, and lessons might be learned from successful developments elsewhere in the UK.

    2014-12-01

    Full Text Available The purpose of this case study was to describe the three-dimensional biomechanics of common ballet exercises in a ballet dancer with ischial tuberosity apophysitis. This was achieved by comparing kinematics between the symptomatic (i.e. ischial apophyseal symptoms and contralateral lower limbs, as well as via reported pain. Results suggest consistent differences in movement patterns in this dancer. These differences included: 1 decreased external rotation of contralateral hip, hence a decreased hip contribution to ‘turn out’; 2 increased contralateral knee adduction and internal rotation; 3 an apparent synchronicity in the contralateral lower limb of the decreased hip external rotation and increased knee adduction; and 4 minimal use of ankle plantar/dorsiflexion movement for symptomatic side. Pain related to the left ischial apophysitis was associated with reduced amplitudes especially in fast ballet movements that required large range of motion in flexion and adduction in the left hip joint. These findings suggest that ischial apophysitis may limit dancer’s ballet technique and performance.

    Although there are abundant natural resources in nature reserves, poverty is a common feature of the social economy in the communities surrounding nature reserves. Income from forestry is still the main source for residents living around nature reserves.The structure of inputs and outputs, i.e. productivity, in the forestry sector in nature reserves is quite different from one reserve to another. Productivity can be measured by Data Envelopment Analysis (DEA) methods owing to the characteristics of DEA. The promotion of productivity in nature reserve is an effective way to improve the living condition in areas neighboring nature reserves.Thus, one typical national nature reserve in Hunan is selected in this study with the intent to measure productivity in the area and then to analyze the factors affecting its productivity.

  15. Analysis of Land Deformation on Slope Area using PS InSAR. Case Study: Malang Area

    International Nuclear Information System (INIS)

    The geographical position of Indonesia located between two continents and oceans is strategic, but at large risk of experiencing various disasters. Climate change and vulnerable location (surrounded by plates and geological faults in the Earth's crust) creates an earthquake-prone region and causes land/mudslides. In this paper, PS InSAR method (Persistent Scatterer Interferometric Synthetic Aperture Radar) is implemented to Phased Array type L-band Synthetic Aperture Radar (PALSAR) data to study the potential damage caused by the earthquake or volcanic eruption in Malang vicinity. By comparing the amplitude images periodically, shifting soil can be determined using precise orbital information. The analysis showed a significant decrease of land deformation on slope area in Klojen district in Malang city, reached up to −7.128 mm/year

    The objective of this study was to assess the costs, energy consumption and greenhouse gas (GHG) emissions throughout the biomass supply chain for large scale biofuel production. Two types of energy crop were considered, switchgrass and loblolly pine, as representative of herbaceous and woody biomass. A biomass logistics model has been developed to estimate the feedstock supply system from biomass production through transportation. Biomass in the form of woodchip, bale and pellet was investigated with road, railway and waterway transportation options. Our analysis indicated that the farm or forest gate cost is lowest for loblolly pine whole tree woodchip at $39.7/dry tonne and highest for switchgrass round bale at $72.3/dry tonne. Switchgrass farm gate GHG emissions is approximately 146kgCO2e/dry tonne, about 4 times higher than loblolly pine. The optimum biomass transportation mode and delivered form are determined by the tradeoff between fixed and variable costs for feedstock shipment. PMID:25710677

    An extensive, in-depth study of cardiovascular risk factors (CVRF) seems to be of crucial importance in the research of cardiovascular disease (CVD) in order to prevent (or reduce) the chance of developing or dying from CVD. The main focus of data analysis is on the use of models able to discover and understand the relationships between different CVRF. In this paper a report on applying Bayesian network (BN) modeling to discover the relationships among thirteen relevant epidemiological features of heart age domain in order to analyze cardiovascular lost years (CVLY), cardiovascular risk score (CVRS), and metabolic syndrome (MetS) is presented. Furthermore, the induced BN was used to make inference taking into account three reasoning patterns: causal reasoning, evidential reasoning, and intercausal reasoning. Application of BN tools has led to discovery of several direct and indirect relationships between different CVRF. The BN analysis showed several interesting results, among them: CVLY was highly influenced by smoking being the group of men the one with highest risk in CVLY; MetS was highly influence by physical activity (PA) being again the group of men the one with highest risk in MetS, and smoking did not show any influence. BNs produce an intuitive, transparent, graphical representation of the relationships between different CVRF. The ability of BNs to predict new scenarios when hypothetical information is introduced makes BN modeling an Artificial Intelligence (AI) tool of special interest in epidemiological studies. As CVD is multifactorial the use of BNs seems to be an adequate modeling tool. PMID:26777431

  20. Substance flow analysis in Finland - Four case studies on N and P flows

    Energy Technology Data Exchange (ETDEWEB)

    Antikainen, R.

    2007-07-01

    Nitrogen (N) and phosphorus (P) are essential elements for all living organisms. However, in excess, they contribute to such environmental problems as aquatic and terrestrial eutrophication (N, P), acidification (N), global warming (N), groundwater pollution (N), depletion of stratospheric ozone (N), formulation of tropospheric ozone (N) and poor urban air quality (N). Globally, human action has multiplied the volume of N and P cycling since the onset of industrialization. Themultiplication is a result of intensified agriculture, increased energy consumption and population growth. Industrial ecology (IE) is a discipline, in which human interaction with the ecosystems is investigated using a systems analytical approach. The main idea behind IE is that industrial systems resemble ecosystems, and, like them, industrial systems can then be described using material, energy and information flows and stocks. Industrial systems are dependent on the resources provided by the biosphere, and these two cannot be separated from each other. When studying substance flows, the aims of the research from the viewpoint of IE can be, for instance, to elucidate the ways how the cycles of a certain substance could be more closed and how the flows of a certain substance could be decreased per unit of production (= dematerialization). IE uses analytical research tools such as material and substance flow analysis (MFA, SFA), energy flow analysis (EFA), life cycle assessment (LCA) and material input per service unit (MIPS). In Finland, N and P are studied widely in different ecosystems and environmental emissions. A holistic picture comparing different societal systems is, however, lacking. In this thesis, flows of N and P were examined in Finland using SFA in the following four subsystems: (I) forest industry and use of wood fuels, II) food production and consumption, III) energy, and IV) municipal waste. A detailed analysis at the end of the 1990s was performed. Furthermore, historical

  1. 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

  4. Pancreatic lipoma: An incydentaloma which can resemble cancer – analysis of 13 cases studied with CT and MRI

    International Nuclear Information System (INIS)

    The purpose of this article is to present computed tomography (CT) and magnetic resonance imaging (MRI) findings of rare pancreatic lipomas. The analysis covered 13 patients (7 men and 6 women, aged 47–88, average: 65.6 years), with 13 pancreatic lipomas, whose cases constituted the basis for 10 contrast-enhanced CT and 5 MRI studies. Lipomas measured from 6 mm to 32 mm (average 12.8 mm) and were located in the pancreatic head (n=7), body (n=2), tail (n=3) and uncinate process (n=1). Most lesions (n=11) were homogenous, well-circumscribed. On contrast-enhanced CT scans, macroscopic fat (<−30 HU) was present in 9 lipomas. In one case (10 mm lesion) the density was −20 HU and the lesion was poorly circumscribed with septations, which altogether made it difficult to precisely characterize its contents. On MR scans fat was demonstrated in all studied cases (n=5). Lipomas are rare, small, homogenous and well-circumscribed pancreatic tumours. The most important feature, decisive for the diagnosis and distinguishing them from pancreatic carcinoma, is detection of fatty tissue on CT and MR scans. In these cases differential diagnosis includes other rare fatty tumours of the pancreas (focal fatty infiltration, teratoma, liposarcoma)

    Full Text Available Technological progress in tunneling has led to modern and efficient tunneling methods in vast underground spaces even under inappropriate geological conditions. Identification and access to appropriate and sufficient geological hazard data are key elements to successful construction of underground structures. Choice of the method, excavation machine, and prediction of suitable solutions to overcome undesirable conditions depend on geological studies and hazard analysis. Identifying and investigating the ground hazards in excavating urban tunnels by an EPB machine could augment the strategy for improving soil conditions during excavation operations. In this paper, challenges such as geological hazards, abrasion of the machine cutting tools, clogging around these tools and inside the chamber, diverse work front, severe water level fluctuations, existence of water, and fine-grained particles in the route were recognized in a study of Tehran subway line 7, for which solutions such as low speed boring, regular cutter head checks, application of soil improving agents, and appropriate grouting were presented and discussed. Due to the presence of fine particles in the route, foam employment was suggested as the optimum strategy where no filler is needed.

    Environmentally extended input-output analysis (EEIOA) has long been used to quantify global and regional environmental impacts and to clarify emission transfers. Structural path analysis (SPA), a technique based on EEIOA, is especially useful for measuring significant flows in this environmental-economic system. This paper constructs an imports-adjusted single-region input-output (SRIO) model considering only domestic final use elements, and it uses the SPA technique to highlight crucial routes along the production chain in both final use and sectoral perspectives. The results indicate that future mitigation policies on household consumption should change direct energy use structures in rural areas, cut unreasonable demand for power and chemical products, and focus on urban areas due to their consistently higher magnitudes than rural areas in the structural routes. Impacts originating from government spending should be tackled by managing onsite energy use in 3 major service sectors and promoting cleaner fuels and energy-saving techniques in the transport sector. Policies on investment should concentrate on sectoral interrelationships along the production chain by setting up standards to regulate upstream industries, especially for the services, construction and equipment manufacturing sectors, which have high demand pulling effects. Apart from the similar methods above, mitigating policies in exports should also consider improving embodied technology and quality in manufactured products to achieve sustainable development. Additionally, detailed sectoral results in the coal extraction industry highlight the onsite energy use management in large domestic companies, emphasize energy structure rearrangement, and indicate resources and energy safety issues. Conclusions based on the construction and public administration sectors reveal that future mitigation in secondary and tertiary industries should be combined with upstream emission intensive industries in a

    Innovative approaches in nanotechnology can provide drug delivery systems with a high potential in different fields. To avoid trial and error assays as a main driving force governing new designs and, furthermore, to develop successful nanosystem optimization strategies, it is of the greatest importance to develop specific characterisation techniques beyond conventional determinations of size, zeta potential and morphology. However, the application of techniques able to determine some key characteristics, such as nanostructure (i.e., solid structure vs vesicular), and the way in which the reorganization of components takes place on these structures has been scarcely explored. The present work has been devoted to provide some insights about the potential offered by some NMR techniques to those scientists working on nanotechnological approaches. For this purpose, we selected our nanosystems based on sorbitan monooleate as a case study. We used (1)H NMR methods, including a recently proposed method relying in the well-known Saturation Transfer Difference (STD) experiment for the observation of 'invisible signals' in large aggregates (Invisible State STD or ISSTD). Overall, these techniques revealed the presence in these nanosystems of a gradient of flexibility from an internal rigid core towards a more flexible region located on their surface, as well as the absence of water content in both regions. Such structure, corresponding to a solid nanostructure rather than a vesicular one, can explain some of the interesting properties previously observed for these innovative nanosystems, such as their high stability, and allows us to refer to these nanosystems with the term "Solid Sorbitan esters Nanoparticles" (SSN). On the basis of the valuable information provided by the mentioned characterisation techniques, it is our understanding that they could facilitate the future design of new drug delivery nanosystems as well as the improvement of existing ones and/or the

  10. Atmospheric organic nitrogen deposition: Analysis of nationwide data and a case study in Northeast China

    International Nuclear Information System (INIS)

    The origin of atmospheric dissolved organic nitrogen (DON) deposition is not very clear at present. Across China, the DON deposition was substantially larger than that of world and Europe, and we found significant positive correlation between contribution of DON and the deposition flux with pristine site data lying in outlier, possibly reflecting the acute air quality problems in China. For a case study in Northeast China, we revealed the deposited DON was mainly derived from intensive agricultural activities rather than the natural sources by analyzing the compiled dataset across China and correlating DON flux with NH4+–N and NO3−–N. Crop pollens and combustion of fossil fuels for heating probably contributed to summer and autumn DON flux respectively. Overall, in Northeast China, DON deposition could exert important roles in agro-ecosystem nutrient management and carbon sequestration of natural ecosystems; nationally, it was suggested to found rational network for monitoring DON deposition. -- Highlights: •Contribution and deposition flux of DON across China was positively correlated. •Deposited DON was more influenced by human in China than across the world and Europe. •DON of a farmland in Northeast China was mainly derived from agricultural activities. •Crop pollen and combustion of fossil fuels contributed to summer and autumn DON. •Deposited DON should not be neglected when evaluating its ecological impacts. -- Synthesis of DON deposition across China implied regional importance of anthropogenic sources, and an observation in Northeast China suggested the ecological significances of the DON flux should be considered

    This study focused on the big landslide case at a section of the high-speed railway line linking Madrid and Gijón (Spain), currently under construction. The movement terrain characterization is a particularly complex one. It partially reaches the "Teso Tunnel" (230 m) (where concrete milimetric fissures were observed) and a stretch of the platform (250 m). They are located in the "Sotiello-Camponames" section (Asturias, N Spain), which is 4,3 km long and had a budget of 79,8 million euros. In this area the bedrock is formed by carboniferous formations: sequences of shales and siltstones with sandstones and coal bed interlayered. The bedrock shows a significant superficial alteration. In a preliminary investigation, 25 inclinometers were installed on the slope and were monitored for 3 years (2007-2010) to study the depth and speed of the slide. These showed slips > 90 mm at depths between 10 and 40 m. Furthermore, a global geological model of the slope was developed based on data provided by 25 boreholes. This large amount of information was integrated in to a GIS database, together with digital elevation models and remote sensing images at different times that helped to analyze the slip. Several geological profiles were modelled to compare the observed movements. The results obtained revealed a deep slide which involving the bedrock. The total area and volume of the primary sliding mass were estimated at 250.000 m2 and 5,5 million m3, respectively. The main vector displacement of the landslide and the railway line form approximately an angle of 70º. The tunnel excavation and the creation of slopes in the landslide toe, as well as the building of two dumps in the head seems to be acting as triggering factors. The chosen technical solution, which is currently under construction, consists of two 165 m lengths parallels pile walls. Moreover, a 6 m diameter and 330 m length drainage gallery has been drilled parallel to the section to lower the ground water level. This

    ENGLISH ABSTRACT: Value engineering (VE has been effectively applied in many different areas. The results have been very encouraging, and many companies accept VE not only as a tool to reduce costs, but also to improve the quality of their produce and streamline their systems. This paper attempts to highlight the application of VE in agriculture, as in pistachio tree farms in Iran. It is found that by implementing VE, unnecessary cultivation costs are lowered. Many of the other factors that lead to the inefficient use of resources could be resolved. In this study, the province of Yazd Iran was studied. Unfortunately there are cases of mismanagement and problems in agriculture management; and the problems must be resolved to make the system of pistachio growing more efficient. The prime objective of this paper is to introduce the concept of value engineering and highlight its application in pistachio farms. The results suggest that it is essential to use Indian Neem pesticide, because it is economically feasible and environmentally friendly to pistachio trees.

    Full Text Available This article demonstrates the potential of applying GIS viewshed analysis to Roman urban studies. It examines the visual dynamics of the Roman city of Empúries, Spain, through an analysis of the visibility of, and view from, a temple and a domus within the city. The analysis proves that the two buildings in question would have had wide views of the Gulf of Roses to the east of the city, and could easily have been seen by people in boats in the Gulf, but they were virtually invisible from within the city and would certainly not have dominated the cityscape. The article concludes that the absence of the villa and temple from the intramural cityscape of Empúries cautions modern investigators of ancient cities against simply assuming that currently prominent ruins on hills or ridges were also highly visible from near as well as far in antiquity.

    , but is also a very populated area, this being factors that favour a high susceptibility level. In addition, the majority of the buildings are included in the first and second categories of seismic risk, being built between 1875 and 1940, the age of the buildings establishing an increased vulnerability to natural hazards. The methodology was developed through the contribution of three partner universities from Bucharest: the University of Bucharest, the Academy for Economic Studies and the Technical University of Constructions. The method suggested was based on the analysis and processing of digital and statistical spatial information resulted from 1:500 topographical plans, satellite pictures, archives and historical maps used for the identification of the age of the buildings. Also, an important stage was represented by the field investigations that resulted with the data used in the assessment of the buildings: year of construction, location and vicinity, height, number of floors, state and function of the building, equipment and construction type. The information collected from the field together with the data resulted from the digitization of the ortophotoplans were inserted in ArcGIS in order to compile the database. Furthermore, the team from the Cybernetics Faculty developed a special software package in Visual Studio and SQL server in order to insert the sheets in GIS so that they could be statistically processed. The final product of the study is a program that includes as main functions editing, the analysis based on selected factors (individual or group) and viewing of building information in the shape of maps or 3D visualization. The strengths of the informational system resulted are given by the extended range of applicability, the short processing period, accessibility, capacity of support for a large amount of information and, thus, standing out as an adequate instrument to fit the needs of a susceptible population.

  15. Analysis of economic feasibility of sale of surplus electricity in cogeneration: case study

    International Nuclear Information System (INIS)

    The production of energy in large quantity and at competitive prices is crucial for economic development, which allied to the environmental question, has incentivated the use of renewable sources of energy. One of the most promising sources of renewable energy is the cogeneration from the residues of cane. Currently, the scenario for this kind of energy production is not consolidated, as production prices are not stable, inducing a risky situation for the environment. This work was aimed to study the economic viability of installing a main site for cogeneration of electricity, in a regional sugarcane factory located in the central region of Sao Paulo state that currently uses residues of sugar cane as fuel. The risk factor that was taken into consideration was the price paid for the MWh sold to the Chamber of Commerce of Electricity. The Monte Carlo Method was used to assess the risk factors for the analysis, by using of New Present Value (NPV), in a scenario that uses 20% of the initial investment made by the energy dealer. After the simulations were finished, considering the conditions used in this work, the project tends to be not feasible, as the behavior of the prices of cogenerated MWh are not sufficient for paying the initial investment and the operational costs.

    The aim of this study was the adaptation of the micro-PIXE method for analysis of nutritionally relevant heavy elements in different tissues of the grain of common buckwheat ( Fagopyrum esculentum), as a representative nutritionally interesting grain food source. At 57% of the buckwheat grain biomass, the endosperm was a modest nutrient source when compared to the cotyledons, at 17% of the biomass. These latter contained high concentrations of trace elements, representing 91% of the total grain Zn, 87% for P, 70% for S, 62% for Mg, 60% for K, 54% for Cu, 53% for Mn and 35% for Fe. The husk provided storage for 85% of the total Ca, 84% for Al, 83% for Si, 76% for Cl, 69% for Ti and 46% for Fe. Knowledge on these preferential elemental constitutions of the different grain tissues makes the possibility of designing target products with nutritionally optimal constitution more feasible. These data represent a basis for a more targeted approach to nutritional improvement of grains intended for human consumption.

    2015-01-01

    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.

    Full Text Available Project priority strategy is the benchmarking of a corporate operation management strategy and in particular is used by a projects-based research and development firm in the complex competence environment of the information and communication technology (ICT industry. This research takes the variables of external environments and internal resources into account for a firm’s market, technology, and finance assets in order to present a decision process on a project priority strategy. This empirical study also addresses the key factors of the interaction between business on a project development’s supply chain: clients, the examined firm, and suppliers. The findings indicate that a profit-driven project can dominate the firm’s strategic operations and management from the resource-based view and analytic hierarchy process technique perspectives. At the same time, the analysis results contribute significant values to project decision management, which is highly recommended for small-medium enterprises conducting product/project development, project portfolio management, and strategic business management.

    The need for timely, accurate, and interoperable geospatial information is steadily increasing. In this context, process-based image processing systems will be the initial segment for future's automatic systems. A process-based system is believed to be a good approach for agricultural purpose because agricultural activities are carried out according to a periodic (annual) cycle. Therefore, a process-based image analysis procedure was designed for routine crop classification for an agricultural region in Kırklareli, Turkey. The process tree developed uses a multi-temporal image data set as an input and gives the final crop classification as an output by using an incremental rule set. The test data set was composed of five images of Satellite Pour l'Observation de la Terre 4 (SPOT 4) data acquired in 2007. Basically, image objects were first extracted and then classified. A rule set was structured depending on class definitions. A decision-based process was executed and formed a multilevel image classification system. The final classification was obtained by merging classes from the appropriate levels where they were extracted. To evaluate the success of the application the accuracy of the classification was assessed. The overall accuracy and kappa index of agreement was found to be 80% and 0.78, respectively. At the end of the study, problems of segmentation and classification operations were discussed and solution approaches were outlined. To assess the process in terms of its scope for automation, the efficiency and success of the rule set were also discussed.

    Full Text Available Background: One of the elements of a logistics system is the subsystem of production, which is a system composed of physical elements such as machinery, tools and (most importantly people. In addition, system-dependent human operators are particularly prone to problems related to discomfort, which can affect production quality and increase training costs and absenteeism. The aim of this study was to assess the workload and risk of musculoskeletal discomfort (MSD's in the process of order fulfillment for the position of packer and to conduct an analysis of risk factors. Methods: The Rapid Entire Body Assessment (REBA evaluation method was used. Activities related to the fulfillment of an order were assessed for three workstations. Results: Five postures qualified for action category (AC 2, seven postures for AC 3 and one posture for AC 4. The main factors affecting the risk of a negative assessment of posture were keeping the back bent and twisted, keeping the arms raised above the trunk, working in a standing position and the weight of packaged carton. Conclusions: Packers working on research positions face a high level of exposure to the risk of MSD's, therefore corrective actions should be carried out as soon as possible. Ergonomic intervention should be linked to redesigning workstations and methods of working. After making changes to the research workstations, re-evaluation using the REBA method is recommended to verify the effectiveness of the changes.

  3. Economic analysis and optimal energy management models for microgrid systems: A case study in Taiwan

    International Nuclear Information System (INIS)

    Highlights: ► An optimization model of energy supply in microgrid system is formulated. ► Optimal energy management strategies are determined. ► Sensitivity analyses of storage capacity and energy demand is performed. -- Abstract: The purpose of this research is to perform economic analysis, formulate an optimization model, and determine optimal operating strategies for smart microgrid systems. Microgrid systems are electricity supply systems that integrate distributed renewable energy production for local demand. Microgrids are able to reduce transmission losses and improve utilization efficiency of electricity and heat. Further, greenhouse gas emissions are reduced by utilizing an efficient power generation microgrid system. This study presents an energy management model that is used to determine optimal operating strategies with maximum profit for a microgrid system in Taiwan. The smart microgrid system is equipped with energy storage devices, photovoltaic power, and wind power generation systems. Sensitivity analyses of investment in storage capacity and growth in electricity demand are conducted for the smart microgrid model. The results show that appropriate battery capacity should be determined on the basis of both battery efficiency and power supply.

  4. Incorporating methane into ecological footprint analysis. A case study of Ireland

    International Nuclear Information System (INIS)

    Carbon dioxide (CO2) accounting is important to global ecological footprint analysis. However methane (CH4), with a global warming potential (GWP) 25 times that of CO2, should not be neglected as an environmental indicator for informed environmental management. While this is a significant component, the CH4 associated with imported embodied energy should also be included in national greenhouse gas (GHG) inventories. This study proposes an initial method for incorporating methane into ecological footprint analyses and hopes to inform future debate on its inclusion. In order to account for differences in methane intensities from exporting countries, methane intensities for OECD countries were calculated using emission and energy consumption estimates taken directly from National Inventory Reports (NIR), published in conjunction with the Intergovernmental Panel on Climate Change (IPCC). For other countries the methane intensities were estimated using energy balances published by the International Energy Association (IEA) and IPCC default emission factors. In order to estimate embodied organic methane, material imports and exports were translated into units (such as live animals) capable of conversion into methane emissions. A significant increase in Ireland's footprint results from the inclusion of the GWP of methane is included within the footprint calculation. (author)

  5. Input-output analysis in fertilizers sector. A case study of Turkey

    International Nuclear Information System (INIS)

    The types of structural analysis in the input-output model known are forward and backwards ties. Fertilizer sector is tied forwardly agriculture, agri-business, chemistry, petro-chemistry and glass sector. In addition, it tied backwardly mining, chemistry, petro-chemistry, electricity, gas, water and transportation. The effect of backward tie of fertilizer sector is more important than its effect of the forward ties. In this study, by means of the year of 1979, 1985 and 1990 input-output table of Turkey the own situation of fertilizer industry and the production relation with other sectors of the economy have been tired to explain with forward and backwards ties. According to the result of the research it was determined that in 1990, (uj) input coefficient of fertilizer sector is 69 %. That is, 69 percent of the product of fertilizer sector was used as an intermediate goods by other sectors. Therefore, 31 percent of goods produced by fertilizer sector was consumed as a final good. In addition, in this year, (wi) intermediate use coefficient of fertilizer sector is 52 %. (wi) intermediate use coefficient of fertilizer sector decreased from 1973 to 1990, as a result of this final use coefficient (1-wi) increased. Refs. 5 (author)

    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.

  10. Cost and performance analysis of physical protection systems - a case study

    International Nuclear Information System (INIS)

    Design and analysis of physical protection systems requires (1) identification of mission critical assets; (2) identification of potential threats that might undermine mission capability; (3) identification of the consequences of loss of mission-critical assets (e.g., time and cost to recover required capability and impact on operational readiness); and (4) analysis of the effectiveness of physical protection elements. CPA -- Cost and Performance Analysis -- addresses the fourth of these four issues. CPA is a methodology that joins Activity Based Cost estimation with performance-based analysis of physical protection systems. CPA offers system managers an approach that supports both tactical decision making and strategic planning. Current exploratory applications of the CPA methodology address analysis of alternative conceptual designs. Hypothetical data is used to illustrate this process

    for states that have traditionally had 'less transparency' in their military sectors. As case studies, first we investigate how to applied verification measures including remote sensing, off-site environmental sampling and on-site inspections to monitor the shutdown status of plutonium production facilities, and what measures could be taken to prevent the disclosure of sensitive information at the site. We find the most effective verification measure to monitor the status of the reprocessing plant would be on-site environmental sampling. Some countries may worry that sample analysis could disclose sensitive information about their past plutonium production activities. However, we find that sample analysis at the reprocessing site need not reveal such information. Sampling would not reveal such information as long as inspectors are not able to measure total quantities of Cs-137 and Sr-90 from HLW produced at former military plutonium production facilities. Secondly, we consider verification measures for shutdown gaseous diffusion uranium-enrichment plants (GDPs). The GDPs could be monitored effectively by satellite imagery, as one telltale operational signature of the GDP would be the water-vapor plume coming from the cooling tower, which should be easy to detect with satellite images. Furthermore, the hot roof of the enrichment building could be detectable using satellite thermal-infrared images. Finally, some on-site verification measures should be allowed, such as visual observation, surveillance and tamper-indicating seals. Finally, FMCT verification regime would have to be designed to detect undeclared fissile material production activities and facilities. These verification measures could include something like special or challenge inspections or complementary access. There would need to be provisions to prevent the abuse of such inspections, especially at sensitive and non-proscribed military and nuclear activities. In particular, to protect sensitive

  12. A Bayesian Belief Network modelling of organisational factors in risk analysis: A case study in maritime transportation

    International Nuclear Information System (INIS)

    The paper presents an innovative approach to integrate Human and Organisational Factors (HOF) into risk analysis. The approach has been developed and applied to a case study in the maritime industry, but it can also be utilised in other sectors. A Bayesian Belief Network (BBN) has been developed to model the Maritime Transport System (MTS), by taking into account its different actors (i.e., ship-owner, shipyard, port and regulator) and their mutual influences. The latter have been modelled by means of a set of dependent variables whose combinations express the relevant functions performed by each actor. The BBN model of the MTS has been used in a case study for the quantification of HOF in the risk analysis carried out at the preliminary design stage of High Speed Craft (HSC). The study has focused on a collision in open sea hazard carried out by means of an original method of integration of a Fault Tree Analysis (FTA) of technical elements with a BBN model of the influences of organisational functions and regulations, as suggested by the International Maritime Organisation's (IMO) Guidelines for Formal Safety Assessment (FSA). The approach has allowed the identification of probabilistic correlations between the basic events of a collision accident and the BBN model of the operational and organisational conditions. The linkage can be exploited in different ways, especially to support identification and evaluation of risk control options also at the organisational level. Conditional probabilities for the BBN have been estimated by means of experts' judgments, collected from an international panel of different European countries. Finally, a sensitivity analysis has been carried out over the model to identify configurations of the MTS leading to a significant reduction of accident probability during the operation of the HSC

    A study was conducted in which the main determinants of electricity demand in Thailand were investigated. Time-series analysis methods were used, notably the unit root test, the Johansen co-integration test and an error correction model (ECM). The objective was to determine the factors affecting short and long-run electricity consumption. This paper presented annual time series data from 1971 to 2006. The unit root test revealed that all series are non-stationary. The Johansen co-integration test revealed the co-integration between variables and the existence of the long-term relationship between them. Electricity consumption accelerated with the increase in gross domestic product (GDP) and population. In contrast, an increase in commodity price would reduce electricity consumption. The coefficient of population indicated that an increase of 1 million in total population would result in an increase in electricity consumption of 0.099 per cent. Last, the results of ECM revealed that nearly 21 per cent of long-term disequilibrium is adjusted to the current period. The factors that affect electricity consumption include GDP growth, inflation rate and population growth. It was concluded that Thailand should prepare for additional power generation from clean energy sources such as solar, biomass and wind energy. Thailand's Energy Policy and Planning Office revealed that electricity consumption in 2008 would be over 130,000 GWh with per capita consumption at nearly 2,000 kWh. The power peak demand will be nearly 24,000 MW in 2008. This result was based on the forecasting model that considered only GDP growth. However, electricity consumption depends not only on the GDP growth, but also upon the other key variables such as population, electricity selling price, consumer price index and temperature. 17 refs., 5 tabs., 4 figs.

    2013-04-01

    In recent years the interest in the forecast and prevention of natural hazards related to hydro-meteorological events has increased the challenge for numerical weather modelling, in particular for limited area models, to improve the quantitative precipitation forecasts (QPF) for hydrological purposes. After the encouraging results obtained in the MAP D-PHASE Project, we decided to devote further analyses to show recent improvements in the operational use of hydro-meteorological chains, and above all to better investigate the key role played by temperature during snowy precipitation. In this study we present a reanalysis simulation of one meteorological event, which occurred in November 2008 in the Piedmont Region. The attention is focused on the key role of air temperature, which is a crucial feature in determining the partitioning of precipitation in solid and liquid phase, influencing the quantitative discharge forecast (QDF) into the Alpine region. This is linked to the basin ipsographic curve and therefore by the total contributing area related to the snow line of the event. In order to assess hydrological predictions affected by meteorological forcing, a sensitivity analysis of the model output was carried out to evaluate different simulation scenarios, considering the forecast effects which can radically modify the discharge forecast. Results show how in real-time systems hydrological forecasters have to consider also the temperature uncertainty in forecasts in order to better understand the snow dynamics and its effect on runoff during a meteorological warning with a crucial snow line over the basin. The hydrological ensemble forecasts are based on the 16 members of the meteorological ensemble system COSMO-LEPS (developed by ARPA-SIMC) based on the non-hydrostatic model COSMO, while the hydrological model used to generate the runoff simulations is the rainfall-runoff distributed FEST-WB model, developed at Politecnico di Milano.

    Full Text Available Analysis of genomic data is increasingly becoming part of the livestock industry. Therefore the routine collection of genomic information would be an invaluable resource for management of breeding programs in small, endangered populations. The objectives of this project were to analyse 1. linkage disequlibrium decay and the effective population size; 2. Inbreeding level and effective population size (NeROH based on runs of homozygosity (ROH; 3. Prediction of genomic breeding values (GEBV within and across breeds. In addition, the use of genomic information for breed management is discussed. The study was based on all available genotypes of Tyrol Grey AI bulls. ROHs were derived based on regions covering at least 4 Mb, 8 Mb and 16 Mb regions, with the corresponding mean inbreeding coefficients 4.0%, 2.9% and 1.6%, respectively. The NeROH was 125 (NeROH>16Mb, 186 (NeROH>8Mb and 370 (NeROH>4Mb, indicating strict avoidance of close inbreeding in the population.The genomic selection was developed for and is working well in large breeds. Contrary to the expectations, the accuracy of GEBVs with very small within breed reference populations were very high, between 0.13-0.91 and 0.12-0.63, when EBVs and dEBVs were used as pseudo-phenotypes, respectively. Subsequent analyses confirmed the high accuracies being heavily influenced by parent averages. Multi-breed and across breed reference sets gave inconsistent and lower accuracies. Genomic information may have a crucial role in management of small breeds. It allows to assess relatedness between individuals, trends in inbreeding and to take decisions accordingly. These decisions would be based on the real genome architecture, rather than conventional pedigree information, which can be missing or incomplete. We strongly suggest the routine genotyping of all individuals that belong to a small breed in order to facilitate the effective management of endangered livestock populations.

  1. Shared Service Center vs. Shared Service Network: A Multiple Case Study Analysis of Factors Impacting on Shared Service Configurations

    Science.gov (United States)

    Becker, Jörg; Niehaves, Björn; Krause, Andreas

    Shared services have proven to be a key element when it comes to increasing government efficiency by collaboration. Here, we seek to investigate into the shared services phenomenon in the context of government reforms. For this purpose, an interview and document analysis-based multiple case study has been conducted in Germany. The qualitative analysis covers two shared service implementations on the local government level and identifies important preconditions for shared service emergence, namely cost pressure as motive, the existence of key actors promoting the topic and the existence of prior cooperation. Moreover, it is shown that the structure of such previous cooperation determines, if shared services are being organised in a centralised (shared service centre) or decentralised format (shared service network).

  2. Performance analysis of electricity generation by the medium temperature geothermal resources: Velika Ciglena case study

    International Nuclear Information System (INIS)

    During the last decade, a design of an energy efficient and cost effective geothermal plant represents a significant and on-going technical challenge in all the Western Balkan countries. In the Republic of Croatia, the geothermal field Velika Ciglena is identified as one of the most valuable geothermal heat sources and probably the location where the first geothermal plant in the Western Balkan area will be built. The purpose of this work is the conceptual design and performance analysis of the binary plants–the one which operates under the Organic Rankine Cycle (ORC) and the other under Kalina (KLN) cycle–which can be used for geothermal energy utilization in Velika Ciglena. A conceptual plant design is performed by the equation-oriented modelling approach and supported by the two steady-state spreadsheet simulators. The performance analysis of all design solutions is conducted through energy and exergy analysis, and by the estimated total cost of operating units in the plant. The results of the analysis indicate that the plant design based on the ORC cycle has a higher thermodynamic efficiency and lower cost of equipment, and consequently, it is more suitable for the future geothermal plant in Velika Ciglena. - Highlights: ► Paper presents the analysis of binary geothermal plant for the utilization of recourses in Velika Ciglena field (Croatia). ► Thermodynamic and economical parameters of both cycles are calculated by the spreadsheet simulation software. The results of performance analysis indicate the advantage of electricity production based on ORC cycle

    Texts and software that we are currently using for teaching multivariate analysis to non-statisticians lack in the delivery of confirmatory factor analysis (CFA). The purpose of this paper is to provide educators with a complement to these resources that includes CFA and its computation. We focus on how to use CFA to estimate a "composite reliability" of a psychometric instrument. This paper provides guidance for introducing, via a case-study, the non-statistician to CFA. As a complement to our instruction about the more traditional SPSS, we successfully piloted the software R for estimating CFA on nine non-statisticians. This approach can be used with healthcare graduate students taking a multivariate course, as well as modified for community stakeholders of our Center for American Indian Community Health (e.g. community advisory boards, summer interns, & research team members). The placement of CFA at the end of the class is strategic and gives us an opportunity to do some innovative teaching: (1) build ideas for understanding the case study using previous course work (such as ANOVA); (2) incorporate multi-dimensional scaling (that students already learned) into the selection of a factor structure (new concept); (3) use interactive data from the students (active learning); (4) review matrix algebra and its importance to psychometric evaluation; (5) show students how to do the calculation on their own; and (6) give students access to an actual recent research project.

    Residential water use is gradually becoming the focus in China's municipal water supply planning and management in recent years. Little is known, however, about the residential water use in modem China due to the transition of economy and enhancement of management on water conservation. In order to better understand the characteristics of residential water use in North China, a model for identifying the determinants of residential water use was established and analyzed by using panel data and cross-section data methodologies. Then Taiyuan city, the capital city of Shanxi Province in Northern China was selected as a case study. Both the analyses and field investigation indicate that the relatively slow increase of residential water use in recent years may result from the implementation of strict laws and regulations on water conservation. And through the investigation,first-hand information about water consumption pattern, water reuse/conservation, people's attitude toward water quantity and quality, etc. have been obtained.

    Flood and drought are two main meteorological catastrophes that have created adverse consequences to more than 80% of total casualties universally, 50% by flood and 31% by drought. Those natural hazards have the tendency of increasing frequency and degree of severity and it is expected that climate change will exacerbate their occurrences and impacts. In addition, growing population and society interference are the other key factors that pressure on and exacerbate the adverse impacts. Consequently, nowadays, the loss from any disasters becomes less and less acceptable bringing about more people's consciousness on mitigation measures and management strategies and policies. In general, due to the difference in their inherent characteristics and time occurrences flood and drought mitigation and protection have been separately implemented, managed, and supervised by different group of authorities. Therefore, the objective of this research is to develop an integrated mitigation measure or a management policy able to surmount both problems to acceptable levels and is conveniently monitored by the same group of civil servants which will be economical in both short- and long-term. As aforementioned of the distinction of fundamental peculiarities and occurrence, the assessment processes of floods and droughts are separately performed using their own specific techniques. In the first part of the research flood risk assessment is focused in order to delineate the flood prone area. The study area is a river plain in southern Thailand where flooding is influenced by monsoon and depression. The work is mainly concentrated on physically-based computational modeling and an assortment of tools was applied for: data completion, areal rainfall interpolation, statistical distribution, rainfall-runoff analysis and flow model simulation. The outcome from the simulation can be concluded that the flood prone areas susceptible to inundation are along the riparian areas, particularly at the

As revealed by the value chain analysis, the role of CPI in this value chain is highly significant. All poultry inputs (DOC, feed, veterinary medicine, and poultry equipments are supplied by CPI. As for downstream sector, CPI processes broiler into its derivatives. The type of value chain governance between feed supplier, DOC, and veterinary medicine, poultry equipment, and poultry derivates belongs to market value chain. Whereas the type of value chain governance between carcass supplier and restaurant belongs to captive value chain. Based on the margin of marketing analysis, the party that gains the lowest margin is farmer and the party that receives the highest margin is the processor. In gap analysis, the lowest attribute of competitiveness is the feed spending and the highest attribute is the spending on veterinary medicine for two months. Factors that influence the competitiveness in poultry industry are condition, demand, industry competition, main industries and supporting industries, and government’s role.Keywords: Value Chain, Competitiveness, Broiler, PT.

    International Nuclear Information System (INIS)

    This paper describes the renovation and replacement problems of small district heating systems (DHS), which are characteristic to small towns in Lithuania and other Central and East European (CEE) countries. These problems have been scarcely investigated till present and are still the subject of acute energy policy discussions. The focus of this paper is economic analysis of heat generation costs with the aim to get an answer to the question: whether existing small DHS should be renovated or replaced by individual heating systems. The paper gives an economic analysis of heat generating costs for various technological solutions and capacities suitable for the needs of heat consumers in small towns. The analysis includes long-run heat generating costs in natural gas and biofuel boiler houses and CHP installations, including individual buildings and small DHS. Four small towns in Lithuania with the population below 40,000 were selected for the economic analysis. The economic, financial and technical state of DHS operated in these towns is different and reflects the diversity of DHS in Lithuania. The least cost heat-generating solutions for individual and district heating were investigated. The barriers for market penetration of new technologies were disclosed under Lithuania's conditions. The findings can also be useful for other CEE countries with similar problems

    Full Text Available Reforming the administrative procedures through the implementation of an e-Government programe is an on-going important process for governments around the world. The benefits of using ICT as a catalyst for increasing the efficiency of administrative procedures are well known and confirmed. The implementation of computer based information systems and providing a possibility for institutions to share data and documents among themselves will create conditions for introducing one stop shop electronic services, which will lead to simplifying administrative procedures. The new simplified administrative services will be of great benefit to citizens. Yet, the institutions will face a significant reduction in the number of issued documents required for providing administrative services, which will lead to positive financial implications. In that regard, the goal of this paper is to make an analysis of the financial aspects of introducing one stop shop services in the Republic of Macedonia by using computer based information systems. The analysis was conducted using public data for the administrative services which are currently provided by a closed set of 16 Macedonian government institutions. In this analysis we calculate the financial implications on citizens, businesses, institutions, and other entities in the society. The result of the analysis is the calculation of the overall savings for the society, which can be used by decision-makers in order to adjust the degree of investments in information systems and necessary complementary assets needed for introduction of these services.

    Ali Beheshti

    2013-01-01

    Full Text Available The Gotvand-Olya Dam is a rock-fill dam, located at Khuzestan province in southwest of Iran. Since the dam is subjected to the daily water level fluctuation, such as rapid drawdown and refill, thus induce a structural impact on the behavior of dam body, it draws many soil engineering concerns. In this paper, seepage analysis of the rock-fill dam was primarily conducted to evaluate the dam safety against the leakage through the dam body. Traditionally, steady-state analysis was employed to investigate the seepage in the dam body, summing that water level is fixed at two cases: high and low water levels. Consequently, it was not able to properly reflect the time-dependent characteristics of seepage phenomena. In this study, seepage analysis was numerically performed using 2-D FEM transient analysis. As a particular boundary condition for an analysis, the water level fluctuation was incorporated to simulate the daily changes. As a result, various seepage phenomena were quantified such as hydraulic gradient, seepage vector and pore water pressure distribution at the corresponding time of interest as the water level rises and recedes. At steady state analysis, the seepage flux at high water level in downstream area was predicted to be 78 l/s. In additions, the seepage flux measured and estimated were both acceptable considering design criteria. The result of this study proves that there is no sign of hazardous sources contributing to the possibility of piping, internal erosion and excess leakage through the dam body.

  19. A gap analysis methodology for collecting crop genepools: a case study with phaseolus beans.

    Directory of Open Access Journals (Sweden)

    Julián Ramírez-Villegas

    Full Text Available BACKGROUND: The wild relatives of crops represent a major source of valuable traits for crop improvement. These resources are threatened by habitat destruction, land use changes, and other factors, requiring their urgent collection and long-term availability for research and breeding from ex situ collections. We propose a method to identify gaps in ex situ collections (i.e. gap analysis of crop wild relatives as a means to guide efficient and effective collecting activities. METHODOLOGY/PRINCIPAL FINDINGS: The methodology prioritizes among taxa based on a combination of sampling, geographic, and environmental gaps. We apply the gap analysis methodology to wild taxa of the Phaseolus genepool. Of 85 taxa, 48 (56.5% are assigned high priority for collecting due to lack of, or under-representation, in genebanks, 17 taxa are given medium priority for collecting, 15 low priority, and 5 species are assessed as adequately represented in ex situ collections. Gap "hotspots", representing priority target areas for collecting, are concentrated in central Mexico, although the narrow endemic nature of a suite of priority species adds a number of specific additional regions to spatial collecting priorities. CONCLUSIONS/SIGNIFICANCE: Results of the gap analysis method mostly align very well with expert opinion of gaps in ex situ collections, with only a few exceptions. A more detailed prioritization of taxa and geographic areas for collection can be achieved by including in the analysis predictive threat factors, such as climate change or habitat destruction, or by adding additional prioritization filters, such as the degree of relatedness to cultivated species (i.e. ease of use in crop breeding. Furthermore, results for multiple crop genepools may be overlaid, which would allow a global analysis of gaps in ex situ collections of the world's plant genetic resources.

    Full Text Available This paper presents the hydrological analysis and grain size characteristics of fluvial sediments in a river basin and their combination to characterize a flood event. The overall objective of the research is the development of a practical methodology based on experimental surveys to reconstruct the hydraulic history of ungauged river reaches on the basis of the modifications detected on the riverbed during the dry season. The grain size analysis of fluvial deposits usually requires great technical and economical efforts and traditional sieving based on physical sampling is not appropriate to adequately represent the spatial distribution of sediments in a wide area of a riverbed with a reasonable number of samples. The use of photographic sampling techniques, on the other hand, allows for the quick and effective determination of the grain size distribution, through the use of a digital camera and specific graphical algorithms in large river stretches. A photographic sampling is employed to characterize the riverbed in a 3 km ungauged reach of the Tescio River, a tributary of the Chiascio River, located in central Italy, representative of many rivers in the same geographical area. To this end, the particle size distribution is reconstructed through the analysis of digital pictures of the sediments taken on the riverbed in dry conditions. The sampling has been performed after a flood event of known duration, which allows for the identification of the removal of the armor in one section along the river reach under investigation. The volume and composition of the eroded sediments made it possible to calculate the average flow rate associated with the flood event which caused the erosion, by means of the sediment transport laws and the hydrological analysis of the river basin. A hydraulic analysis of the river stretch under investigation was employed to verify the validity of the proposed procedure.

    Hypoglycemia is a common problem among neonates. Transient in nature, it usually resolves with an increase in glucose intake. However, as clinicians, we must recognize that prolonged hypoglycemia may be caused by increased insulin production. Nesidioblastosis is one cause of persistent hyperinsulinism of the newborn. This case study reviews fetal physiology, neonatal presentation, and treatment. PMID:9325879

    When analyzing the risk for a region where landslides constitute a threat for the society and the environment, a fully quantitative approach often becomes impracticable. The magnitude, frequency and location of landslides and a reasonably complete inventory of historical events is commonly not available. Likewise, a thorough investigation of the damaged assets and quantification of losses is rarely possible. Nevertheless, an alternative approach can be engaged in areas where information regarding the environmental conditions leading to the occurrence of landslides including their relative location, and the characteristics and distribution of elements at risk are known. This contribution proposes a methodology for a landslide risk analysis applicable at regional scale taking into account the spatial probability and consequences of past damaging events. Since the temporal information used to calculate the detailed hazard probability is missing, a susceptibility analysis is performed by using a data-driven Bayesian method (Weights of Evidence modeling technique) which analyzes the relation between a training set (past landslide events) and multiple predisposing factors (lithology, landuse, slope, aspect, internal relief, altitude), in order to predict areas that are less-to-more susceptible to landslide initiation. The consequence analysis is based on a generalized assessment of vulnerability, exposure and value of the elements at risk (i.e. buildings and roads) using cadastral and statistical data. For both components of the risk analysis (susceptibility analysis and consequence analysis) an estimation of uncertainty is performed by defining a central value (which represents the statistical mean) and a measure of value range (minimum and maximum) of the input parameters. As the procedure operates at a spatial level, the distribution of risk and the annual probability of expected losses are expressed numerically as well as spatially with the use of GIS. The developed

  4. Thermal analysis of a magnesio-thermic reactor - a typical case study

    International Nuclear Information System (INIS)

    The reduction of uranium tetrafluoride with magnesium is an excellent example of reaction system in which it is the heat transfer associated with the process which determines its feasibility, performance and safety aspects. This paper presents an analysis of the thermal conditions prevailing during the course of this reaction. Noting that the reaction is a violent one accompanied by changes in physical state, considerable density changes and an indefinite reaction mechanism it seems almost impossible to carry out a thermal analysis of the system. However, based on general observations and simple energy balances it has been possible to derive the equations for the peak-reaction temperature (which is important from reaction yield as well as safety point of view) and heat utilization factor. The derived equations are presented. (author)

    1999-03-01

    In 1988 two large earthquakes with magnitude of Ms 7.6 and Ms 7.2 occurred in Lancang-Genma area, Southwest China. This paper discusses the determination of the spatial distribution of fault slip caused by the earthquakes using geodetic surveys. The prior information obtained from geological surveys and seismological investigations was used to determine the geometry of the fault plane and the average fault slip. The smooth constraints on the fault slips have been described by a normal distribution with hyperparameters, which are incorporated in the inversion analysis with a Bayesian model. Akaike's Bayesian Information Criterion (ABIC) is used to get the optimal values of hyperparameters. Once the hyperparameters are determined, the maximum likelihood method is employed to estimate the patterns of a fault slip. Based on the results of inverse analysis monitoring geodetic surveys can be properly designed and conducted to obtain crust deformations and predict potential earthquake sources.

    Combining algae cultivation and wastewater treatment for biofuel production is considered the feasible way for resource utilization. An updated comprehensive techno-economic analysis method that integrates resources availability into techno-economic analysis was employed to evaluate the wastewater-based algal biofuel production with the consideration of wastewater treatment improvement, greenhouse gases emissions, biofuel production costs, and coproduct utilization. An innovative approach consisting of microalgae cultivation on centrate wastewater, microalgae harvest through flocculation, solar drying of biomass, pyrolysis of biomass to bio-oil, and utilization of co-products, was analyzed and shown to yield profound positive results in comparison with others. The estimated break even selling price of biofuel ($2.23/gallon) is very close to the acceptable level. The approach would have better overall benefits and the internal rate of return would increase up to 18.7% if three critical components, namely cultivation, harvest, and downstream conversion could achieve breakthroughs.

    This research investigated the quality of groundwater of 298 wells during 10 years, in Fars province, southern Iran, to survey spatial variation of groundwater quality and also major sources of hydro-chemical components for drinking and agricultural uses. To classify the sampling stations in each year, hierarchical cluster analysis, using the Euclidean distances and "Ward" method, was used. According to the results of cluster analysis, there were three quality groups in groundwater of the research area: first group of 170 wells with type of Ca-HCO3, second group of 98 wells with type of Ca-HCO3, and third group of 30 wells with type of Na-Cl. Hydro-chemical parameters were increased from the first to the third group, and on the basis of Schoeller and USSL diagrams, the water of wells of the third group was considered unsuitable for irrigation and drinking. Principal component (PC) analysis and factor analysis reduced the complex and voluminous data matrix into three main components, accounting for more than 80 % of the total variance. The first PC contained TDS, EC, TH, Na(+), Cl(-), Mg(2+), SO4 (2-), Ca(2+), and SAR parameters. Therefore, the first dominant factor was salinity. In PC2, HCO3 and pH were the dominant parameters, which may indicate weathering of silicate minerals. The PC3 contained high loadings for NO2 (2-) and NO3 (-). This factor indicates anthropogenic contaminants that may be caused by improper disposal of domestic wastes or the use of chemical fertilizers in agriculture and leaching of them. PMID:27317054

  4. Multicriteria analysis of agricultural raw materials: A case study of BSBIOS and PETROBRAS BIOFUELS in Brazil

    International Nuclear Information System (INIS)

    Energy crises reverberate within societies and encourage worldwide change in this industry. In this context, Brazil has been consolidating the National Program for the Production and Use of Biodiesel (Programa Nacional de Produção e Uso do Biodiesel—PNPB). This article analyzes BSBIOS and PETROBRAS BIOFUELS, which is a company that is incorporated under the PNPB. After providing an overview, the manuscript focuses on the criteria used for the selection of the agricultural raw materials used in the biodiesel industry. A reference model that considered the economic, technological, and social dimensions was developed; these dimensions were analyzed in relation to the production matrices of the soybean, canola, sunflower, and castor plants. The company strategically opted to establish programs for promoting the production of only soybean and canola. In the short term, the company has accepted the evidence that the main source of raw materials is soybean production. This decision was made considering the multicriteria analysis that was developed, which involved a number of economic, technological, and social aspects. Consequently, this analysis used in the decision-making process exhibits both a macro (the national and international environment) and a micro perspective (the companies’ reality). - Highlights: • The economic viability of biodiesel production in Brazil hinges on crop production. • Biodiesel production in Brazil requires developing an efficient production chain. • Oleaginous crops will be diversified by creating a network of suppliers. • Raw material production is diversifying based on an analysis of relevant factors

    Full Text Available In­tro­duc­ti­on: We aimed to contribute to the epidemiological database of our country with regard to corrosive material ingestions. Materials and Methods: We retrospectively analyzed 139 cases of corrosive ingestion who were admitted to Pediatric Surgery Department of Akdeniz University between 2005 and 2010. Cases were evaluated in terms of age, gender, socioeconomic level, the active substance and levels of the burn. In addition some of the data were obtained by phone contacts with the families. Results: The mean age of the most frequent intake of corrosive was 3.35±1.93. It was determined that most of the children were male. More than half of the mothers were primary school graduates and working. It was found that caustic substance intake was found to be most frequent in summer months. It was also determined that children took ether phosphate most frequently and that mothers of children purchased caustic substances in a closed container, but these substances were divided to another utensil at home. It was found that children ingested caustic substances found in their homes and families were brought their children to the hospital without doing anything. Conclusions: The increasing diversity of corrosive substances used in household cleaning, constitutes a great danger for children. In this respect, especially families at risk groups should be identified and these families need to be informed about the dangers of corrosive materials.

    IL-10 expression limits inflammation and restricts the size of CNS damage from stroke. In this study, we examined the correlation between cerebral infarction (CI) and serum levels of interleukin-10 (IL-10) using a combination of case-control study and meta-analysis of published data, with an aim of understanding the relevance of serum IL-10 levels to CI development. This study enrolled a total of 169 CI patients admitted to the Second Hospital of Hebei Medical University between May 2011 and November 2014. During the same period, a group of 145 individuals were recruited at the same hospital as healthy controls after thorough physical examination. Serum IL-10 levels were measured by enzyme-linked immunosorbent assay (ELISA). SPSS 19.0 (IBM, 2010, Chicago, IL, USA) and Comprehensive Meta-Analysis 2.0 (CMA 2.0) software were used for data analysis. Serum levels of IL-10 (pg/mL) were significantly lower in CI patients when compared to healthy controls (15.36 ± 3.21 vs. 21.64 ± 5.17, t = 13.12, P  0.05). Logistic regression analysis indicated that, with the exception of triglyceride (TG) and uric acid (UA) levels (both P > 0.05), the other seven parameters, including fasting blood glucose (FPG), total cholesterol, low-density lipoprotein (LDL), high-density lipoprotein (HDL), creatinine (Cr), systolic blood pressure (SBP), and diastolic blood pressure (DBP), strongly correlated with CI development (all P relationship in Asians (SMD = 2.522, 95 % CI 0.468~4.576, P = 0.016) but not in Caucasians (P > 0.05). Our study provided convincing evidence that the patients with CI exhibit consistently reduced serum levels of IL-10, and IL-10 may be a major player in the development and progression of CI.

  11. Dynamic energy performance analysis: Case study for energy efficiency retrofits of hospital buildings

    International Nuclear Information System (INIS)

    This paper investigates several actions for the energy refurbishment of some buildings of the University Hospital Federico II of Naples. The analysis focuses on a specific lot of 4 buildings, representative of the whole district hospital. For those structures, sustainable energy savings actions are investigated. They regard the installation of: i) roofs thermal insulation; ii) a substation climatic 3-way valve; iii) radiators thermostatic valves; iv) AHU (air handling unit) time-programmable regulation. This paper aims at presenting an investigation methodology, useful for designers and other stakeholders involved in hospital energy refurbishments, based on an integrated approach which combines dynamic energy performance simulations and experimental campaigns. In order to measure all the simulations' missing input parameters, a suitable experimental analysis, including measurements of temperature, humidity, flow rate and density of construction materials, is performed. A thermographic investigation is also performed for investigating the building envelope performance. This analysis showed that significant savings can be achieved especially by adopting radiators thermostatic valves and AHU regulations. Coherently, the installation of a 3-way valve in the substation does not determine significant additional savings when radiators thermostatic valves are already installed. For high-rise buildings, roofs insulation returns only marginal reductions of space heating and cooling demands. - Highlights: • Energy saving measures applied to the largest hospital of South Italy are analyzed. • A new approach combining dynamic simulations and measurements is implemented. • Thermography, temperature and flow measurements are performed. • High savings are achieved by adopting thermostatic valves and AHU control systems. • The simplest energy saving actions resulted to be the most profitable ones

  17. Digital Curvatures Applied to 3D Object Analysis and Recognition: A Case Study

    CERN Document Server

    Chen, Li

    2009-01-01

    In this paper, we propose using curvatures in digital space for 3D object analysis and recognition. Since direct adjacency has only six types of digital surface points in local configurations, it is easy to determine and classify the discrete curvatures for every point on the boundary of a 3D object. Unlike the boundary simplicial decomposition (triangulation), the curvature can take any real value. It sometimes makes difficulties to find a right value for threshold. This paper focuses on the global properties of categorizing curvatures for small regions. We use both digital Gaussian curvatures and digital mean curvatures to 3D shapes. This paper proposes a multi-scale method for 3D object analysis and a vector method for 3D similarity classification. We use these methods for face recognition and shape classification. We have found that the Gaussian curvatures mainly describe the global features and average characteristics such as the five regions of a human face. However, mean curvatures can be used to find ...

    Full Text Available Ecotourism can be defined as responsible travel to natural areas that conserves the environment and cultural heritage and improves the well-being of local people. Sustainable planning and management of ecotourism development are important and necessary for increasing positive and decreasing negative effects on the complex environment. This paper analyses the suitability of selected protected natural areas in the Serbian Danube region for the purposes of ecotourism development. The multi-criteria analysis includes several natural and socio-economic factors and criteria which influence ecotourism development. The integration of Geographic Information System (GIS and Analytic Hierarchy Process (AHP greatly facilitates the decision-making process in the ecotourism destination planning. A suitability map of the analysed protected natural areas for ecotourism development as one of the sustainable tourism types is highlighted as a result of this paper. Such analysis assists in the objective promotion of ecotourism destinations and thus contributes to the improvement of Serbian tourism development.

  5. Material flow analysis for an industry - A case study in packaging

    Science.gov (United States)

    Amey, E.B.; Sandgren, K.

    1996-01-01

    The basic materials used in packaging are glass, metals (primarily aluminum and steel), an ever-growing range of plastics, paper and paperboard, wood, textiles for bags, and miscellaneous other materials (such as glues, inks, and other supplies). They are fabricated into rigid, semi-rigid, or flexible containers. The most common forms of these containers include cans, drums, bottles, cartons, boxes, bags, pouches, and wraps. Packaging products are, for the most part, low cost, bulky products that are manufactured close to their customers. There is virtually no import or export of packaging products. A material flow analysis can be developed that looks at all inputs to an industrial sector, inventories the losses in processing, and tracks the fate of the material after its useful life. An example is presented that identifies the material inputs to the packaging industry, and addresses the ultimate fate of the materials used. ?? 1996 International Association for Mathematical Geology.

    2015-12-01

    In this paper, we discuss the application of an airborne gravity survey to sedimentary basin analysis. Using high-precision airborne gravity data constrained by drilling and seismic data from the Bohai Bay Basin in eastern China, we interpreted faults, structural elements, sedimentary thickness, structural styles and local structures (belts) in the central area of the Basin by the wavelet transform method. Subsequently, these data were subtracted from the Bouguer gravity to calculate the residual gravity anomalies. On this basis, the faults were interpreted mainly by linear zones of high gravity gradients and contour distortion, while the sedimentary thicknesses were computed by the Euler deconvolution. The structural styles were identified by the combination of gravity anomalies and the local structures interpreted by the first vertical derivative of the residual gravity. The results showed evidence for seven faults, one sag and ten new local structure belts.

  7. Analysis of physical flows in primary commodity trade. A case study in China

    International Nuclear Information System (INIS)

    How globalization and international trade affect sustainable development and environment has attracted worldwide attention. Associated with the import and export of primary commodities, ecologically important materials have been exchanged among regions and countries. China, having the largest population in the world and the highest economic growth rate in last decades, may have an important influence on global sustainable development through the trade of primary commodities. Using the data from Almanac of China's Foreign Economic Relations and Trade, we analyzed material flows in the trade of primary commodity in China from 1950 to 2001. Our analysis shows that: (1) China has turned from a net exporter of primary commodities to a net importer; (2) minerals and fuels have been the major imports of primary commodities since 1992, just as well as foods and minerals did in 1980s; (3) most of the net imported primary commodities come from Oceania, Africa and Latin America.

Using the SWOT analytical model, this paper provides pertinent comparative analysis of the medical tourism destinations here being Malaysia, Thailand, Singapore and India. Each destination possesses its own value propositions to convince the demands of medical tourists. Malaysia and Thailand have a good mixture of elements (medical, tourism and wellness to be an excellent medical tourism destination while Singapore and India need further development in some of these elements. Meeting or exceeding the medical tourists’ expectations and requirements are the priority of medical tourism destination marketers in ensuring a successful medical tourism industry development.

  9. INTEGRATION OF POKA YOKE INTO PROCESS FAILURE MODE AND EFFECT ANALYSIS: A CASE STUDY

    Directory of Open Access Journals (Sweden)

    A. P. Puvanasvaran

    2014-01-01

    Full Text Available The Failure Mode and Effect Analysis (FMEA is a one of the requirements which was required by the Automotive Industries Action Group (AIAG to all the automotive suppliers and manufacturers worldwide through the TS16949 Quality System. There were a lot of dicrepencies detected on implementing the FMEA which directly related to the user experinces and knowledge. The descrepencies cause the FMEA not meeting the objectives of it. Conceptually, Poka Yoke is able to fit into the Process FMEA. Failure Mode and Effect Analysis (FMEA helps predict and prevent problems through proper control or detection methods. Mistake proofing emphasizes detection and correction of mistakes before they become defects. Poka Yoke helps people and processes work correctly the first time. It refers to techniques that make mistakes impossible to commit. These techniques eliminate defects from products and processes as well as substantially improve their quality and reliability. Poka Yoke can be considered an extension of FMEA. The use of simple Poka Yoke ideas and methods in product and process design eliminates both human and mechanical errors. Ultimately, both FMEA and Poka Yoke methodologies result in zero defects and benefit either the end or the next-in-line customer. The first concept of Poka Yoke emphasizes elimination of the cause or occurrence of the error that creates the defects by concentrating on the cause of the error in the process. The defect is prevented by stopping the line or the machine when the root cause of the defect is triggered or detected. The second concept of Poka Yoke focuses on the effectiveness of the detection system. The foolproof detection system eliminates the defect or detects the error that causes defects. The implementation of the Poka Yoke concept in a foolproof detection system eliminates the possibility that error or defects will slip through the process and reach the customer.

  10. A Support Analysis Framework for mass movement damage assessment: applications to case studies in Calabria (Italy

    Directory of Open Access Journals (Sweden)

    O. Petrucci

    2009-03-01

    Full Text Available The analysis of data describing damage caused by mass movements in Calabria (Italy allowed the organisation of the Support Analysis Framework (SAF, a spreadsheet that converts damage descriptions into numerical indices expressing direct, indirect, and intangible damage.

    The SAF assesses damage indices of past mass movements and the potential outcomes of dormant phenomena re-activations. It is based on the effects on damaged elements and is independent of both physical and geometric phenomenon characteristics.

    SAF sections that assess direct damage encompass several lines, each describing an element characterised by a value fixed on a relative arbitrary scale. The levels of loss are classified as: L4: complete; L3: high; L2: medium; or L1: low. For a generic line l, the SAF multiplies the value of a damaged element by its level of loss, obtaining dl, the contribution of the line to the damage.

    Indirect damage is appraised by two sections accounting for: (a actions aiming to overcome emergency situations and (b actions aiming to restore pre-movement conditions. The level of loss depends on the number of people involved (a or the cost of actions (b.

    For intangible damage, the level of loss depends on the number of people involved.

    We examined three phenomena, assessing damage using the SAF and SAFL, customised versions of SAF based on the elements actually present in the analysed municipalities that consider the values of elements in the community framework. We show that in less populated, inland, and affluent municipalities, the impact of mass movements is greater than in coastal areas.

    The SAF can be useful to sort groups of phenomena according to their probable future damage, supplying results significant either for insurance companies or for local authorities involved in both disaster management and planning of defensive measures.

  11. Genetic analysis of the vitamin D receptor gene in two epithelial cancers: melanoma and breast cancer case-control studies

    International Nuclear Information System (INIS)

    Vitamin D serum levels have been found to be related to sun exposure and diet, together with cell differentiation, growth control and consequently, cancer risk. Vitamin D receptor (VDR) genotypes may influence cancer risk; however, no epidemiological studies in sporadic breast cancer (BC) or malignant melanoma (MM) have been performed in a southern European population. In this study, the VDR gene has been evaluated in two epithelial cancers BC and MM. We have conducted an analysis in 549 consecutive and non-related sporadic BC cases and 556 controls, all from the Spanish population, and 283 MM cases and 245 controls. Genotyping analyses were carried out on four putatively functional SNPs within the VDR gene. An association with the minor allele A of the non-synonymous SNP rs2228570 (rs10735810, FokI, Met1Thr) was observed for BC, with an estimated odds ratio (OR) of 1.26 (95% CI = 1.02–1.57; p = 0.036). The synonymous variant rs731236 (TaqI) appeared to be associated with protection from BC (OR = 0.80, 95%CI = 0.64–0.99; p = 0.047). No statistically significant associations with MM were observed for any SNP. Nevertheless, sub-group analyses revealed an association between rs2228570 (FokI) and absence of childhood sunburns (OR = 0.65, p = 0.003), between the 3'utr SNP rs739837 (BglI) and fair skin (OR = 1.31, p = 0.048), and between the promoter SNP rs4516035 and the more aggressive tumour location in head-neck and trunk (OR = 1.54, p = 0.020). In summary, we observed associations between SNPs in the VDR gene and BC risk, and a comprehensive analysis using clinical and tumour characteristics as outcome variables has revealed potential associations with MM. These associations required confirmation in independent studies

  1. Landslide susceptibility analysis using Probabilistic Certainty Factor Approach: A case study on Tevankarai stream watershed, India

    Indian Academy of Sciences (India)

    Evangelin Ramani Sujatha; G Victor Rajamanickam; P Kumaravel

    2012-10-01

    This paper reports the use of a GIS based Probabilistic Certainty Factor method to assess the geo-environmental factors that contribute to landslide susceptibility in Tevankarai Ar sub-watershed, Kodaikkanal. Landslide occurrences are a common phenomenon in the Tevankarai Ar sub-watershed, Kodaikkanal owing to rugged terrain at high altitude, high frequency of intense rainfall and rapidly expanding urban growth. The spatial database of the factors influencing landslides are compiled primarily from topographical maps, aerial photographs and satellite images. They are relief, slope, aspect, curvature, weathering, soil, land use, proximity to road and proximity to drainage. Certainty Factor Approach is used to study the interaction between the factors and the landslide, highlighting the importance of each factor in causing landslide. The results show that slope, aspect, soil and proximity to roads play important role in landslide susceptibility. The landslide susceptibility map is classified into five susceptible classes – low, very low, uncertain, high and very high − 93.32% of the study area falls under the stable category and 6.34% falls under the highly and very highly unstable category. The relative landslide density index (R index) is used to validate the landslide susceptibility map. R index increases with the increase in the susceptibility class. This shows that the factors selected for the study and susceptibility mapping using certainty factor are appropriate for the study area. Highly unstable zones show intense anthropogenic activities like high density settlement areas, and busy roads connecting the hill town and the plains.

Simple and multiple regression techniques have been used for gauging the determinants of corporate philanthropy after collecting data from audited financial reports of banks. Approach: A sample study was derived from all banks that have been listed on the Amman Stock Exchange (ASE during the 4 year period were sampled. Twelve banks qualified to be included in the study sample. Results: Provide some support for the theory that giving enhanced shareholder value, as firms in the same industry tend to adopt similar giving practices and firms that advertise more intensively also give more to charity. But much of our evidence indicated that agency costs play a prominent role in explaining corporate giving it was found that there is a statistically significant between earning before tax, firm size, advertising intensity, number of employees and salaries and wage expenses on Philanthropy measured by donations in every year and all the period of the study. Conclusion: The main recommendation presented in this study is that there is a need to motivate the corporate sector towards social involvement. To achieve that Ministry of finance or governments should recognize highest corporate philanthropists with awards and appreciations at national level. Build human resource development through technical support, training or internships in the management of philanthropic organizations.

  4. Remote sensing and gis application in wetland change analysis: case study of kallar kahar

    International Nuclear Information System (INIS)

    Wetlands are the one of the naturally occurring habitat. They provide invaluable biodiversity resources, aids in water quality improvement, support ground water recharge, help in moderating climate change and supply flood control but they are deteriorated greatly due to economic development and population growth. In the present analysis, the object-based approach of 'ENVI' is presented to derive the change detection inventory information for Kallar Kahar Wetland using Quick bird imagery and Corona imagery. According to the results, agricultural and shrub area has reduced by 43% and 49% respectively whereas there has been an increase in the water-body, uncultivated/soiled area, orchard and built-up area by 40%, 53%, 79% and 38%, respectively. In order to analyse the change detection of Wetlands using very high resolution satellite images, the outcome of the analyses is presented which can help in decision making for the purpose of land development and further assess the implications of the observed changes in the area for making appropriate recommendations.

  5. Anomalous dispersion analysis of inhibitor flexibility: a case study of the kinase inhibitor H-89

    International Nuclear Information System (INIS)

    The anomalous dispersion signal of the bromine-containing kinase inhibitor H-89 was used to characterize discrete binding modes of the compound when complexed with the catalytic subunit of protein kinase A. With its ability to show the interactions between drug-target proteins and small-molecule ligands, X-ray crystallography is an essential tool in drug-discovery programmes. However, its usefulness can be limited by crystallization artifacts or by the data resolution, and in particular when assumptions of unimodal binding (and isotropic motion) do not apply. Discrepancies between the modelled crystal structure and the physiological range of structures generally prevent quantitative estimation of binding energies. Improved crystal structure resolution will often not aid energy estimation because the conditions which provide the highest rigidity and resolution are not likely to reflect physiological conditions. Instead, strategies must be employed to measure and model flexibility and multiple binding modes to supplement crystallographic information. One useful tool is the use of anomalous dispersion for small molecules that contain suitable atoms. Here, an analysis of the binding of the kinase inhibitor H-89 to protein kinase A (PKA) is presented. H-89 contains a bromobenzene moiety that apparently binds with multiple conformations in the kinase ATP pocket. Using anomalous dispersion methods, it was possible to resolve these conformations into two distinct binding geometries

    Full Text Available This paper presents the design analysis of a photovoltaic (PV system to power the CAD/CAM Laboratory at the Department of Mechanical Engineering, University of Port Harcourt. Life cycle cost and break-even point analyses are also carried out to assess the economic viability of the system. The unit cost of electricity for the designed PV system is high compared to the current unit cost of the municipally supplied electricity, but will be competitive with lowering cost of PV system components and favourable government policies on renewable energy. The approach and data provided are useful for designing solar systems in the area. The automated MS Excel spreadsheet developed could be used for the design and economic analyses of PV system in any other geographical region once the input data are sorted. Since about 90% of businesses in Nigeria currently own diesel generators, it is expected that future work should be devoted to the optimum combination of PV-Battery-Diesel system in electricity generation for optimum economic benefits to the country.

  7. Field gas chromatography analysis as input for vadose zone modeling: A case study

    International Nuclear Information System (INIS)

    At Williams Air Force Base (AFB) in Mesa, Arizona, jet fuel contamination in the vadose zone was characterized using field gas chromatograph (GC) analysis only. Because of the thick vadose zone at Williams AFB (210 ft), a cost-effective field program that gathered enough data to adequately characterize the site for multiphase flow and transport modeling had to be developed. Because the data would be used only as input into the modeling effort, the project team decided to maximize the amount of field screening data while eliminating the fixed-base laboratory data. The field program included drilling 15 borings 215 ft below land surface, just below the groundwater table, collecting split-spoon soil samples at 10-ft intervals, and analyzing all samples for total petroleum hydrocarbons (Modified 8015 JP-4 standard) and benzene, toluene, ethylbenzene, and xylenes (Method 8020) using an on-site field GC. The data were input into the two-dimensional Multiphase Flow and Transport Computer Model (MOTRANS). The model was calibrated to existing site conditions by simulating a jet fuel spill near ground surface and projecting migration for 20 years, which corresponds to the estimated amount of time since the first fuel spill at the Base

    Full Text Available Considering that individuals can fulfill some of their needs at the workplace, we may assume that, from the moment people choose a job, they are oriented toward those organizations that ease needs’ satisfaction and quitting that job is less likely when the dominant work needs are met. This paper aims to identify and analyze the needs of public servants from the North-West Region of Romania. The research was conducted in two distinct parts: the identification of needs was made using interviews and the analysis was based on data collected by self-administrated questionnaires. Specific needs of public servants were identified, along with general needs which are expressed by employees from other sectors. 77 needs were analyzed and they were grouped in 22 dimensions following the application of a questionnaire to 343 employees. The results showed that there are three major needs that public servants have namely the need for an optimal organizational climate, the need to have a career and the need to have specific work characteristics.

    Full Text Available This paper shows how the systematic approach in software testing using static code analysis method can be used for improving the software quality of a BCI framework. The method is best performed during the development phase of framework programs. In the proposed approach, we evaluate several software metrics which are based on the principles of object oriented design. Since such method is depending on the underlying programming language, we describe the method in term of C++ language programming whereas the Qt platform is also currently being used. One of the most important metric is so called software complexity. Applying the software complexity calculation using both McCabe and Halstead method for the BCI framework which consists of two important types of BCI, those are SSVEP and P300, we found that there are two classes in the framework which have very complex and prone to violation of cohesion principle in OOP. The other metrics are fit the criteria of the proposed framework aspects, such as: MPC is less than 20; average complexity is around value of 5; and the maximum depth is below 10 blocks. Such variables are considered very important when further developing the BCI framework in the future.

    The spatial features and attribute data of urban forests in Shenyang arboretum were acquired by using aerial photographs and field investigation. After systemic and quantitative analysis of the species composition and spatial distribution pattern of urban forest community based on geographic information system (GIS), the following results were achieved: 1) the vegetation in the arboretum was rich and in a good condition. Phellodendron amurense, Robinia pseudoacacia, and Ulmus punita were the main species according to their abundant individuals and relative dominance. The spatial distribution pattern of this vegetation indicated that it was in a growing level and in the best state for ecological benefits; 2) the tree species relative dominance based on vegetation quantity had no distinct relationship with the species abundance, and the species having abundant individuals might have a low relative dominance; and 3) the curve displayed in the relationship diagram between tree individuals and tree height showed ascending and protruding. With the increment of tree height class, the individuals were unchanged nearly at the beginning, but when the height was more than 12 m, the individuals reduced distinctly, and the curve displayed a quickly declined trend. The relationship between tree individuals and tree diameter at the breast height (DBH) showed the same result. PMID:15031894

  11. Using ICD for structural analysis of clusters: a case study on NeAr clusters

    International Nuclear Information System (INIS)

    We present a method to utilize interatomic Coulombic decay (ICD) to retrieve information about the mean geometric structures of heteronuclear clusters. It is based on observation and modelling of competing ICD channels, which involve the same initial vacancy, but energetically different final states with vacancies in different components of the cluster. Using binary rare gas clusters of Ne and Ar as an example, we measure the relative intensity of ICD into (Ne+)2 and Ne+Ar+ final states with spectroscopically well separated ICD peaks. We compare in detail the experimental ratios of the Ne–Ne and Ne–Ar ICD contributions and their positions and widths to values calculated for a diverse set of possible structures. We conclude that NeAr clusters exhibit a core–shell structure with an argon core surrounded by complete neon shells and, possibly, further an incomplete shell of neon atoms for the experimental conditions investigated. Our analysis allows one to differentiate between clusters of similar size and stochiometric Ar content, but different internal structure. We find evidence for ICD of Ne 2s−1, producing Ar+ vacancies in the second coordination shell of the initial site. (paper)

    2015-12-31

    The molecular electrostatic potential (MESP) of the CS2 molecule, in conjunction with the cluster building algorithm, is utilized for generating trial geometries of medium-sized (CS2)n (n = 5-8) aggregates. MESP features suggest crossed, parallel stacked, T-shaped and L-shaped geometries for CS2 clusters. These initial geometries are subjected to geometry optimization employing second-order Møller-Plesset (MP2) theory, with correlation consistent aug-cc-pvDZ (aDZ) basis set. Single-point energies at MP2/aTZ levels are calculated for the estimation of binding energies at complete basis set (CBS) limit. The minimal nature of the reported structures is confirmed by doing vibrational frequency run at MP2/aDZ level of theory using the molecular tailoring approach (MTA). The two- and three-body interaction energies are computed for clusters with n = 5, 6, and 7 and these are suggestive of change in contact patterns with increasing n. Such an analysis is found to offer a qualitative explanation of the packing pattern found in the crystal structure. PMID:26650761

    2016-04-01

    Two multifamily buildings planned in Climate Zone 4 were analyzed to determine the cost, energy and performance implications of redesigning them to comply with Zero Energy Ready Home, a recognition program of the U.S. Department of Energy. Energy modeling was conducted on one representative apartment in each building using BEopt. Construction costs were obtained from the developer and subcontractors to determine savings and cost increases over ENERGY STAR. It was found that seven items would be necessary to change to comply with ZERH criteria when starting from the original design which was compliant with ENERGY STAR version 3.0. Design changes were made to the exterior walls, domestic water heating system, duct protection, duct design, garage ventilation, and pest control to comply with ZERH requirements. Energy impacts of upgrading from the original design to ZERH resulted in 2 to 8 percent reduction in modeled source energy consumption, or 1.7 to 10.4 MMBtu per year, although the original design was already about 8 percent better than a design configured to minimum ENERGY STAR criteria. According to the BEopt analysis, annualized energy related costs of the ZERH design were slightly higher for the apartment and slightly lower for the townhome when compared to the original design.

  14. Wind characterization analysis incorporating genetic algorithm: A case study in Taiwan Strait

    International Nuclear Information System (INIS)

    In this paper, the genetic algorithm (GA) is originally applied to compute the Weibull parameters for wind characterization analysis, in which an objective function required in GA for searching optimization solution has been first defined as well. Wind data analyzed are observed at a wind farm in the Taiwan Strait from 2006 to 2008. To accurately describe wind speed distribution three kinds of probability density functions are compared, i.e. the Weibull, logistic and lognormal functions. Statistical parameters including the max error in the Kolmogorov-Smirnov test, root mean square error, Chi-square error and relative error of wind power density are considered as judgment criterions. The results show that GA is a useful method, there is about 33% time saving when compared with conventional iteration method. Weibull function describes best the wind distribution, regardless of time periods. Accordingly, wind power density, availability factor and electrical energy output from an ideal turbine are assessed using the Weibull parameters; utilization rate of wind energy for the currently used turbine is discussed. Further the wind energy compensates very well with solar energy; when solar radiation is down in winter and spring, the wind power becomes greater; energy ratios for each month are calculated lastly. -- Highlights: → The genetic algorithm was applied for the first time to calculate the Weibull parameters for wind energy assessment. → Weibull probability function fits the observed wind speed distribution better than both logistic and lognormal functions. → Wind and solar energy potential in Taiwan show a great complementary relationship.

    An early warning process is the result of interplay between the forecasting and nowcasting interactions. Therefore, (1) an accurate measurement and prediction of the spatial and temporal distribution of rainfall over an area and (2) the efficient and appropriate description of the catchment properties are important issues in atmospheric hazards (severe precipitation, flood, flash flood, etc.). In this paper, a forecasting and nowcasting analysis is presented, regarding a severe precipitation event that took place on September 21, 2015 in Athens, Greece. The severe precipitation caused a flash flood event at the suburbs of Athens, with significant impacts to the local society. Quantitative precipitation forecasts from European Centre for Medium-Range Weather Forecasts and from the COSMO.GR atmospheric model, including ensemble forecast of precipitation and probabilistic approaches are analyzed as tools in forecasting process. Satellite remote sensing data close and six hours prior to flash flood are presented, accompanied with radar products from Hellenic National Meteorological Service, illustrating the ability to depict the convection process.

  18. Flood frequency analysis with uncertainty estimation and its application for hazard assessment - a case study in the Mekong Delta

    2015-04-01

    In many flood-prone regions on earth, the nature of the floods calls for a multivariate approach as analyzing flood frequency, which provides a basic for a sound flood hazard and risk assessment. That is because the flood severity is determined not only by the peak flood discharge as usually considered but also by other aspects such as the volume and even the hydrograph shape of the flood. However, the multivariate flood frequency analysis taking into account its associated uncertainty sources has rarely been studied. The Mekong Delta is one of the largest and most densely populated deltas on Earth. It witnesses annual large scale inundations which are associated to the SE-Asian monsoons. These floods are the basis for the livelihoods of the population of the Delta, but they are also the major hazard. This hazard has, however, not been studied within the frame of a probabilistic flood hazard analysis. Thus this study focuses on the identification of a suitable statistical model for the estimation of flood frequencies considering two important flood aspects peak Q and volume V and exemplifies its applicability for a sound flood hazard assessment for the case study in the Mekong Delta. A copula-based bivariate statistical model with bootstrapping-based uncertainty estimation is, hence, developed for a flood frequency analysis of peak flow and volume. The analysis reveals that even with the available - in a hydrological context - quite long data series (e.g. 88 years in the Mekong Delta), large uncertainties are associated to the bivariate quantiles (Q, V), even for rather frequent events. The main uncertainty source is the sampling uncertainty, thus a direct consequence of the limited length of the data series. However, we still advocate for applying the proposed bivariate frequency method for flood frequency estimation in the Mekong Delta because a) it reflects the essential aspects of floods in this region, b) the uncertainties are inherent for every multivariate

  19. On the feasibility of using emergy analysis as a source of benchmarking criteria through data envelopment analysis: A case study for wind energy

    International Nuclear Information System (INIS)

    The definition of criteria for the benchmarking of similar entities is often a critical issue in analytical studies because of the multiplicity of criteria susceptible to be taken into account. This issue can be aggravated by the need to handle multiple data for multiple facilities. This article presents a methodological framework, named the Em + DEA method, which combines emergy analysis with Data Envelopment Analysis (DEA) for the ecocentric benchmarking of multiple resembling entities (i.e., multiple decision making units or DMUs). Provided that the life-cycle inventories of these DMUs are available, an emergy analysis is performed through the computation of seven different indicators, which refer to the use of fossil, metal, mineral, nuclear, renewable energy, water and land resources. These independent emergy values are then implemented as inputs for DEA computation, thus providing operational emergy-based efficiency scores and, for the inefficient DMUs, target emergy flows (i.e., feasible emergy benchmarks that would turn inefficient DMUs into efficient). The use of the Em + DEA method is exemplified through a case study of wind energy farms. The potential use of CED (cumulative energy demand) and CExD (cumulative exergy demand) indicators as alternative benchmarking criteria to emergy is discussed. The combined use of emergy analysis with DEA is proven to be a valid methodological approach to provide benchmarks oriented towards the optimisation of the life-cycle performance of a set of multiple similar facilities, not being limited to the operational traits of the assessed units. - Highlights: • Combined emergy and DEA method to benchmark multiple resembling entities. • Life-cycle inventory, emergy analysis and DEA as key steps of the Em + DEA method. • Valid ecocentric benchmarking approach proven through a case study of wind farms. • Comparison with life-cycle energy-based benchmarking criteria (CED/CExD + DEA). • Analysts and decision and policy

  10. Water productivity analysis for smallholder rainfed systems: A case study of Makanya catchment, Tanzania

    Science.gov (United States)

    Mutiro, J.; Makurira, H.; Senzanje, A.; Mul, M. L.

    Decreasing food security as a result of ever-increasing population, less water availability and soil degradation is common in countries in sub-Saharan Africa. While most of the developed fresh water resources are heavily committed to irrigation, about 90% of sub-Saharan populations rely solely on rainfed agriculture for their livelihoods. The majority of the population is therefore not directly benefiting from developed water resources but are, in fact, subsistence rainfed farmers. Thus, in sub-Saharan Africa, techniques which help to improve water productivity (WP) can assist in alleviating the impacts of water scarcity especially for crop production purposes. A study was conducted in the semi-arid Makanya catchment in northern Tanzania where farmers depend on rainfed subsistence farming for their livelihoods. The objective of the study was to assess the effect of improved conservation agriculture techniques on WP of a maize crop. An assessment of the current WP in rainfed and partially supplementary irrigated agriculture was made. The crop water requirement for maize in the study area was found to be 508 mm/season by using the CROPWAT model compared to total received rainfall of up to 383.86 mm per study plot during the same period. An attempt was made to separate transpiration from evapotranspiration using a transpiration meter. Results indicate that, currently, WP for maize in the catchment is low (0.18-1.33 kg m -3). Introduction of improved techniques increased WP by between 90% and 110%. Infiltration rates also increased from 6 to 26 cm/h. The conclusion from the research is that, from a purely scientific view, there is room to significantly improve the water use techniques being applied for crop productivity through improving current smallholder farming practices A clear understanding and quantification of the water partitioning processes is required to maximise productive water use by the plant as transpiration and this is directly related to biomass

    Low Impact Development (LID) has been developed since the end of 1990s. Lots of successful experience based on this new technology have been made. Taiwan Executive Yuan is conducting a six-year (2014~2019) program "Integrated River Basin Management Plan" applying LID to build sponge cities. Construction and Planning Agency, Ministry of the Interior is editing the manual of LID technology for Taiwan. However, since the hydrological environments, physiographic conditions, climates, the strength and frequency of disasters in Taiwan are different from that in America, this study takes the first laboratory experiment and model simulation to evaluate the efficiency of application of LID in Taiwan.LID Facilities includes porous pavement, rain garden, green roof, tree box filter facilities and so on, and in this study, porous pavement is taken as an example for discussion. In the part of laboratory experiments, the sand box experiments is designed to operate with the specified rainfall return period calculated by Horton formula and rainfall characteristics of Taipei. Then the outflow hydrograph in each designed rainfall of specified return period can be evaluated. As for model simulation, this study constructs LID simulation elements by SWMM model and tests the suitability for simulation of the outflow hydrograph obtained from experiments, and definitely quantifies the efficiency of water retention and flood reduction of porous pavement. The results fits well with the experimental observation data with less than 10% error of pick flow. It suggests that, with LID simulation elements constructed in this study, the efficiency of LID in actual on-site application can be evaluated.The results shows that porous pavement is able to delay arrival time of pick about 5% ~10% and reduce the pick flow about 5%~20%, and hold the ability of near 3~5% water retention. It proves that application of LID can retain water and reduce flood in Taiwan.

    Full Text Available The present study is an outcome of a concern for the teaching of English as a foreign language (EFL in Libyan schools. Learning of a foreign language is invariably linked to learners building a good repertoire of vocabulary of the target language, which takes us to the theory and practice of imparting training in vocabulary learning strategies (VLSs to learners. The researcher observed that there exists a divergence in theoretical knowledge of VLSs and practically training learners in using the strategies in EFL classes in Libyan schools. To empirically examine the situation, a survey was conducted with secondary school English teachers. The study discusses the results of the survey. The results show that teachers of English in secondary school in Libya are either not aware of various vocabulary learning strategies, or if they are, they do not impart training in all VLSs as they do not realize that to achieve good results in language learning, a judicious use of all VLSs is required. Though the study was conducted on a small scale, the results are highly encouraging.Keywords: vocabulary learning strategies, vocabulary learning theory, teaching of vocabulary learning strategies

  4. Spatial GHG Inventory: Analysis of Uncertainty Sources. A Case Study for Ukraine

    International Nuclear Information System (INIS)

    A geoinformation technology for creating spatially distributed greenhouse gas inventories based on a methodology provided by the Intergovernmental Panel on Climate Change and special software linking input data, inventory models, and a means for visualization are proposed. This technology opens up new possibilities for qualitative and quantitative spatially distributed presentations of inventory uncertainty at the regional level. Problems concerning uncertainty and verification of the distributed inventory are discussed. A Monte Carlo analysis of uncertainties in the energy sector at the regional level is performed, and a number of simulations concerning the effectiveness of uncertainty reduction in some regions are carried out. Uncertainties in activity data have a considerable influence on overall inventory uncertainty, for example, the inventory uncertainty in the energy sector declines from 3.2 to 2.0% when the uncertainty of energy-related statistical data on fuels combusted in the energy industries declines from 10 to 5%. Within the energy sector, the 'energy industries' subsector has the greatest impact on inventory uncertainty. The relative uncertainty in the energy sector inventory can be reduced from 2.19 to 1.47% if the uncertainty of specific statistical data on fuel consumption decreases from 10 to 5%. The 'energy industries' subsector has the greatest influence in the Donetsk oblast. Reducing the uncertainty of statistical data on electricity generation in just three regions - the Donetsk, Dnipropetrovsk, and Luhansk oblasts - from 7.5 to 4.0% results in a decline from 2.6 to 1.6% in the uncertainty in the national energy sector inventory

    Marine protected areas (MPAs) are implemented worldwide as an efficient tool to preserve biodiversity and protect ecosystems. We used food web models (Ecopath and EcoTroph) to assess the ability of MPAs to reduce fishing impacts on targeted resources and to provide biomass exports for adjacent fisheries. Three coastal MPAs: Bonifacio and Port-Cros (Mediterranean Sea), and Bamboung (Senegalese coast), were used as case studies. Pre-existing related Ecopath models were homogenized and ecosystem characteristics were compared based on network indices and trophic spectra analyses. Using the EcoTroph model, we simulated different fishing mortality scenarios and assessed fishing impacts on the three ecosystems. Lastly, the potential biomass that could be exported from each MPA was estimated. Despite structural and functional trophic differences, the three MPAs showed similar patterns of resistance to simulated fishing mortalities, with the Bonifacio case study exhibiting the highest potential catches and a slightly inferior resistance to fishing. We also show that the potential exports from our small size MPAs are limited and thus may only benefit local fishing activities. Based on simulations, their potential exports were estimated to be at the same order of magnitude as the amount of catch that could have been obtained inside the reserve. In Port Cros, the ban of fishing inside MPA could actually allow for improved catch yields outside the MPA due to biomass exports. This was not the case for the Bonifacio site, as its potential exports were too low to offset catch losses. This insight suggests the need for MPA networks and/or sufficiently large MPAs to effectively protect juveniles and adults and provide important exports. Finally, we discuss the effects of MPAs on fisheries that were not considered in food web models, and conclude by suggesting possible improvements in the analysis of MPA efficiency.

  6. Risk analysis of leukaemia incidence among people living along the Techa River: a nested case-control study

    International Nuclear Information System (INIS)

    Large quantities of radioactive materials released over time from the Mayak nuclear weapons facility caused significant internal and external exposure for people living along the banks of the Techa River (Southern Urals, Russia). We conducted a nested case-control study in the Extended Techa River Cohort to determine whether the risk of leukaemia incidence increased with protracted exposure to ionising radiation or with other non-radiation risk factors. The study included 83 cases identified over 47 years of follow-up and 415 controls matched for sex, age at diagnosis, age (within a 5 year age group), and date of initial residence in the riverside area. External and internal doses have been calculated using the Techa River Dosimetry System 1996 (TRDS96). Conditional logistic regression was used to calculate odds ratios per Gray (OR/Gy) and 95% confidence intervals (95% CI). After excluding cases of chronic lymphoid leukaemia, the OR/Gy of total, external, and internal doses were 4.6 (95% CI: 1.7-12.3), 7.2 (95%CI: 1.7-30.0) and 5.4 (95%CI: 1.1-27.2), respectively. A history of solid tumour, either malignant or benign, before the leukaemia diagnosis was associated with a 2.5-fold increase in the leukaemia risk (95% CI: 1.1-5.9). Even though the analysis of confounders was less useful than expected because of missing data, multivariate analyses that took the exposure dose into account confirmed the association between leukaemia incidence and tumour history

    The concentrations of the aromatic hydrocarbons benzene, toluene, ethylbenzene and the isomeric xylenes (BTEX) have been determined in the indoor air of 115 private non-smoker homes ({approx}380 individual rooms) situated in areas with an extreme traffic situation, i.e. in city streets (street canyons) with high traffic density and in rural areas with hardly any traffic at all. The influence of the traffic on the indoor concentration was apparent in the high traffic area. In order to identify other factors influencing the BTEX concentrations, the data and additional questionnaires were analyzed by univariate and multivariate analysis. The analysis was supplemented by some case studies. It is shown that meteorology (the seasons), the type of room (e.g. living room versus bedroom), the ventilation and, in particular, garages in the house strongly influence the indoor concentration of BTEX. Thus, the indoor BTEX level is significantly higher in winter than in summer. Moreover, garages with a connecting door to the living quarters lead to high indoor concentrations of aromatic hydrocarbons in these rooms. In addition, the storage of solvents and hobby materials, and also the presence of smoking guests increase the BTEX level. If rooms are directly heated by coal or wood, the BTEX level is higher compared to the use of gas heating. Surprisingly, no correlation was found between the building materials used and the BTEX level. Case studies were carried out for two homes with an integrated garage (and a connecting door to the living rooms) and for seven homes where redecoration work was carried out during sampling. In both instances, a pronounced increase was observed in the BTEX concentration. (Author)

    Full Text Available The purposes of this study were to determine the socio-economic characteristics of dairy farmers in Antalya, in Turkey, calculate the gross income, variable costs and gross margin of dairy farms, determine the probability distributions of consequences for alternative decisions to enable dairy farmers as decision makers to make a good and well-informed choice, to determine cross effects of milk prices variations on the productive strategy of dairy farms. The data were gathered via face to face interviews in Korkuteli, Dosemealtı, Elmalı, Manavgat and Serik counties of Antalya province in Turkey. The survey study was conducted with 80 farmers, who were member of Dairy Cow Breaders Union, in the 2011 production period. In this study, on the basis of previous experience, dairy farmers assigned minimum, maximum and most likely values of milk price and yield over the next period of 5 years. Then, triangular and cumulative distributions were defined by using these values. Moreover, Monte Carlo Stochastic Simulation model was developed to obtain distribution of expected gross margin per cow. The model and triangular and cumulative distributions were built in Excel with @Risk add-in software. The relationship of mean risk aversion coefficient, calculated by using negative exponential function, with both average gross margin and gross margin standard deviation values determined for each farm was examined. The results show that the relation between average gross margin and mean risk aversion coefficient was negative and significant at 5% level. But, although the relation between gross margin standard deviation and mean risk aversion coefficient was found to be negative, it was not significant at 5% level.

    Uranium groundwater anomalies, observed before the L'Aquila earthquake (April 6th, 2009) and before the seismic swarm, which occurred in the second half of 2010, represent a key geochemical signal of a progressive increase of deep fluids fluxes at middle-lower crustal levels associated with the geodynamics of the earthquake. In this paper, temporal variations of uranium groundwater are studied in association with the seismic pattern around Gran Sasso National Laboratory (LNGS-INFN). The normalized seismic energy release and the number of earthquakes are analyzed in detail by means of monthly sliding time windows. They are compared with uranium anomalies to highlight any possible correlation.

  14. The cost and benefit analysis of a contaminated area remediation: case study of dose level selection

    International Nuclear Information System (INIS)

    In recent years there has been an increasing awareness of the radiological impact of non-nuclear industries that extract and/or process ores and minerals containing naturally occurring radioactive material (NORM). Without radiological rules, these industrial activities may result in significant radioactive contamination of installations and sites. Depending on the potential hazardous to the environment and public health, the radioactive contaminated sites may require remediation. The extent of the site cleanup is a function of the size, localization, complexity, potential risks and on possible future uses envisioned for the site. Since worker and public health, public anxiety and economics factors are involved; the selection of an appropriate dose level can be quite complicated. This paper discusses the selection of a dose level criterion to remedy a site, which was contaminated by wastes from monazite processing. The site is located in the Sao Paulo city; the most densely populated Brazilian City. In its 60,000 square meters of area, a preliminary survey showed contaminated zones covering an area of 6,500 square meters. In some places, contamination was found below the superficial layer of the soil, being the radionuclide vertical distribution not uniform. The 228 Ra soil activity concentration reached values up to 33,000 Bq/kg while those for 226 Ra reached values up to 6,700 Bq/kg. Based on pathway analysis model and considering both the current land use and a hypothetical residential scenario, the residual contamination levels of radionuclides in soil have been derived for dose values of 10 mSv/y (dose level for intervention), 5 mSv/y, 3 mSv/y, 1 mSv/y (dose limit for practices) and 0.3 mSv/y (dose constraint for practices). An optimized value o f annual dose of about 5 mSv/y would be a good option for intervention level, but taking into account the public concern and anxiety, the site location and size, and the remediation costs, it is suggested the

    The work presents the results of a comprehensive modelling study of surface and groundwater resources in the Muzza-Bassa Lodigiana irrigation district, in Northern Italy. It assesses the impact of changes in land use and irrigation water availability on the distribution of crop water consumption in space and time, as well as on the groundwater resources. A distributed, integrated surface water-groundwater simulation system was implemented and applied to the study area. The system is based on the coupling of a conceptual vadose zone model with the groundwater model MODFLOW. To assess the impact of land use and irrigation water availability on water deficit for crops as well as on groundwater system in the area, a number of management scenarios were identified and compared with a base scenario, reflecting the present conditions. Changes in land use may alter significantly both total crop water requirement and aquifer recharge. Water supply is sufficient to meet demand under present conditions and, from the crop water use viewpoint, a reduction of water availability has a positive effect on the overall irrigation system efficiency; however, evapotranspiration deficit increases, concentrated in July and August, when it may be critical for maize crops.

    Current conventional agricultural systems using intensive energy has to be re-vitalized by new integrated approaches relying on renewable energy resources, which can allow farmers to stop depending on fossil resources. The aim of the present study was to compare wheat production in dryland (low input) and irrigated (high input) systems in terms of energy ratio, energy efficiency, benefit/cost ratio and amount of renewable energy use. Data were collected from 50 irrigated and 50 dryland wheat growers by using a face-to-face questionnaire in 2009. The results showed that the total energy requirement under low input was 9354.2 MJ ha{sup -1}, whereas under high input systems it was 45367.6 MJ ha{sup -1}. Total energy input consumed in both dryland and irrigated systems could be classified as direct, indirect, renewable and non-renewable energies which average in two wheat production systems were 47%, 53%, 24% and 76%, respectively. Energy ratios of 3.38 in dryland and 1.44 in irrigated systems were achieved. The benefit-cost ratios were 2.56 in dryland and 1.97 in irrigated wheat production systems. Based on the results of the present study, dry-land farming can have a significant positive effect on energy-related factors especially in dry and semi-dry climates such as Iran. (author)

    2012-11-01

    Full Text Available This study investigates the energy and cost performance of thirty recent buildings in Melbourne, Australia. Commonly, building design decisions are based on issues pertaining to construction cost, and consideration of energy performance is made only within the context of the initial project budget. Even where energy is elevated to more importance, operating energy is seen as the focus and embodied energy is nearly always ignored. For the first time, a large sample of buildings has been assembled and analyzed to improve the understanding of both energy and cost performance over their full life cycle, which formed the basis of a wider doctoral study into the inherent relationship between energy and cost. The aim of this paper is to report on typical values for embodied energy, operating energy, capital cost and operating cost per square metre for a range of building functional types investigated in this research. The conclusion is that energy and cost have quite different profiles across projects, and yet the mean GJ/m2 or cost/m2 have relatively low coefficients of variation and therefore may be useful as benchmarks of typical building performance.

    Some children with residual deficits in speech production also display characteristics of dyslexia; however, the causes of these disorders--in isolation or comorbidly--remain unknown. Presently, the role of phonological representations is an important construct for considering how the underlying system of phonology functions. In particular, two related skills--speech perception and phonological working memory--may provide insight into the nature of phonological representations. This study provides an exploratory investigation into the profiles of three 9-year-old children: one with residual speech errors, one with residual speech errors and dyslexia, and one who demonstrated typical, age-appropriate speech sound production and reading skills. We provide an in-depth examination of their relative abilities in the areas of speech perception, phonological working memory, vocabulary, and word reading. Based on these preliminary explorations, we suggest implications for the assessment and treatment of children with residual speech errors and/or dyslexia. PMID:26458199

    Jalkanen, Jari; Müser, Martin H.

    2015-10-01

    In this study, we evaluate the functionals of different embedded-atom methods (EAM) by fitting their free parameters to ab-initio results for copper. Our emphasis lies on testing the transferability of the potentials between systems which vary in their spatial dimension and geometry. The model structures encompass zero-dimensional clusters, one-dimensional chains, two-dimensional tilings, and three-dimensional bulk systems. To avoid having to mimic charge transfer, which is outside the scope of conventional EAM potentials, we focus on structures, in which all atoms are symmetrically equivalent. We find that the simple, four-parameter Gupta EAM potential is overall satisfactory. Adding complexity to it decreases the errors on our set of structures only by marginal amounts, unless EAM is modified to depend also on density gradients, higher-order derivatives, or related terms. All tested conventional EAM functions reveal similar problems: the binding energy of closed-packed systems is overestimated in comparison to open or planar geometries, and structures with small coordination tend to be too rigid. These deficiencies can be fixed in terms of a systematically modified embedded-atom method (SMEAM), which reproduces DFT results on bond lengths, binding energies, and stiffnesses or bulk moduli by typically O(1%), O(5%), and O(15%) accuracy, respectively. SMEAM also predicts the radial distribution function of liquid copper quite accurately. Yet, it does not overcome the difficulty to reproduce the elastic tensor elements of a hypothetical diamond lattice.

  5. An analysis of LULC change detection using remotely sensed data; A Case study of Bauchi City

    International Nuclear Information System (INIS)

    Bauchi is one of the cities in the north eastern part of Nigeria that has witnessed tremendous expansion as a result of rapid urbanization. For the past decade, the city has been known to be relatively small both in size and population. But today, Bauchi is one of the fastest growing cities in northern Nigeria. Therefore, it is paramount to detect the nature and magnitude of these changes in order to determine its direction of future expansion. To achieve that, Remotely Sensed data from Landsat 7 ETM+ and Landsat 8 were utilized for the purpose of LULC change detection in Bauchi city. Landsat 7 image of 2003 and Landsat 8 image of 2013 were obtained for the purpose of the study. Three change detection algorithms were used to detect areas of change. They include supervised, unsupervised and post classification comparison. While the unsupervised classification was found to be less effective, the supervised classification produced good results with overall accuracies of 93.5% and 89.7% for the 2003 and 2013 respectively. Finally, ''from-to'' change was obtained using the post classification comparism

    Ensenada health officials lack pertinent information on the sustainable management of solid waste, as do health officials from other developing countries. The aims of this research are: (a) to quantify and analyze the household solid wastes generated in the city of Ensenada, Mexico, and (b) to project biogas production and estimate generation of electrical energy. The characterization study was conducted by socioeconomic stratification in two seasonal periods, and the biogas and electrical energy projections were performed using the version 2.0 Mexico Biogas Model. Per capita solid waste generation was 0.779 ± 0.019 kg per person per day within a 98 % confidence interval. Waste composition is composed mainly of food scraps at 36.25 %, followed by paper and cardboard at 21.85 %, plastic at 12.30 %, disposable diapers at 6.26 %, and textiles at 6.28 %. The maximum capacity for power generation is projected to be 1.90 MW in 2019. Waste generated could be used as an intermediate in different processes such as recycling (41.04 %) and energy recovery (46.63 %). The electrical energy that could be obtained using the biogas generated at the Ensenada sanitary landfill would provide roughly 60 % of the energy needed for street lighting. PMID:23010895

    Bone strength is determined by the mechanical properties of bone material, and the size and shape of the whole bone, i.e., its architecture. The mandible of vertebrates has been traditionally regarded as a beam oriented in relation to main masticatory loads, i.e., the longer dimension of its cross-section being parallel to the load. Rodents follow this pattern but, in addition, their mandible possesses an intriguing arch-like shape that is apparent when seen in the lateral view. Little attention was given to the structural capacity of this trait. The advantage of an arch is that it can withstand a greater load than a horizontal beam. The objective of this study was to model the rodent mandible like an arch to evaluate its structural strength. The bending moment in an arch-like mandible was 15-25% lower with respect to a beam-like mandible. Further, bending varies with mandible "slenderness" and incisor procumbency, a functionally relevant rodent trait. In the rodent Ctenomys talarum (Caviomorpha; Ctenomyidae), bone stress was substantially reduced when the mandible was modeled as an arch-like structure as compared with a beam-like structure, and safety factors were 15-34% higher. The shape of rodents' mandible might confer a functional advantage to high and repeatedly applied loads resulting from a unique feeding mode: gnawing. J.

  8. Analysis of Radon in Shallow-well: A Case Study at Pijit District in Songkhla, Thailand

    International Nuclear Information System (INIS)

    Radon levels were measured in shallow-well samples collected from Pijit district of Songkhla, Thailand. A total of 35 water samples from shallow-well were collected and analyzed for radon concentration. The measurements were performed using RAD7, an electronic radon detector, manufactured by Durridge Company Inc. The radon concentration in these samples is found to vary from (1.39 ± 0.18) to (89 ± 8.11) Bq/l with a mean value of (16.7 ± 2.33) Bq/l. These recorded values are compared with the safe limit values recommended for drinking water by various health and environmental protection agencies. The recorded values of radon concentration are without the safe limit of 11 Bq/l recommended by the US Environmental Protection Agency. The annual effective dose for ingestion and inhalation is also evaluated in this research. The estimated total effective dose varies from 4.72 to 65.69 μSv/year. The total effective dose in all locations of the studied area is found to be within the safe limit (0.1 mSv/year) recommended by World Health Organization and European Council.

  9. Public–private partnerships value in bioenergy projects: Economic feasibility analysis based on two case studies

    International Nuclear Information System (INIS)

    Greece and Italy are facing serious energy challenges concerning sustainability and greenhouse gas emissions as well as security of supply and the competitiveness of the internal energy market. These challenges require investments by the public sector, while the countries have seen in the last years their debts rising. A solution to promote bioenergy business, without rising public debt, could be the use of PPP (Public–Private Partnership). This paper presents a methodology to develop agro-energy business using PPP in two rural areas: the municipality of Evropos (in Greece) and the municipality of Montefalco (in Italy). At first biomass availability is studied, then the optimal technology is selected. Once technological issues have been analyzed PPP value for money has to be assessed. Conventional methods to evaluate economic viability of a project are not enough and a Public-Sector Comparator (PSC) has to be calculated. Typical risks of bioenergy projects are identified, estimating their probabilities and consequences. This will lead to associate a monetary value to each risk. Then the identified risks are allocated among private and public partners, establishing synergies. The allocation of risks will have consequences on the preparation of PPP contract and on partner selection procedure. - Highlights: • PPPs can control or reduce risks in bioenergy business. • Development of a methodology for risk allocation in bioenergy projects. • Development of a methodology for risk valuing in bioenergy projects. • A Public-Sector Comparator has been realized for an agro-energy PPP. • Risk allocation has to be clearly indicated in PPP contract

    Full Text Available Introduction: In Brazil, hantavirus cardiopulmonary syndrome (HCPS has a high lethality rate that varies by region. This study aimed to identify the risk factors associated with fatal hantavirosis. Methods: This study was a case-control study that included all laboratory confirmed cases of hantavirosis. The cases were stratified by the different Brazilian regions using data from the Notifiable Diseases Information System. “Cases” were patients who progressed to death, whereas “controls” were patients who were cured. The odds ratio (OR and the adjusted OR were calculated. Results: Overall, 158 cases and 281 controls were included in this study. In the Midwest region, the cases were 60% less likely to present with flank pain, and the time between the beginning of symptoms and death was shorter than the time between the beginning of symptoms and a cure. In the Southeast region, the cases were 60% less likely to present with thrombocytopenia or reside in rural areas compared to those who progressed to a cure. Additionally, the cases sought medical assistance, notification and investigation more quickly than the controls. In the Southern region, the cases that died were 70% less likely to be male compared to the controls. Conclusions: HCPS manifests with nonspecific symptoms, and there are few published studies related to the condition, so determining a patient's therapeutic strategy is difficult. This study presents findings from different Brazilian regions and highlights the need for further investigations to improve comprehension about regional risk factors associated with hantavirosis and to reduce morbimortality.

    Full Text Available Extended abstract1- IntroductionMankind has always paid attention to the management of waste for millennia. In early times, waste wouldn’t cause a problem entering environment because humans’ population was low and lands were abundantly accessible. But cities emerged and population density increased which caused waste to increase per unit area. Consumables increased in number which caused waste to increase and enter environment. Humans must take into consideration the accurate methods of management as well as the engineering and economic principles in order to fight such infections. Although there’re various methods for dumping waste, the recovering of waste is of the utmost importance nowadays because this method not only decreases the amount of waste and prevents further environmental pollution but also saves money, energy and natural resources. The average daily amount of waste made in the city of Boukan is 150 tons. The amount of waste is never separated and is dumped in a hazardous manner. 2- MethodologyThe method for this applied study is descriptive, analytical and evaluative; and the data is collected from libraries, field studies, and 330 questionnaires conducted utilizing a random sampling method in 3 areas of the city. The city was divided into three parts for data to be analyzed. Then 30 samples of garbage were gathered from homes in each area and were analyzed physically, also hypothesis including two independent variables (the condition and improvement of management, and one dependent variable (the amount of waste decreased were analyzed using SPSS and inferential statistics (simple linear regression, Pearson's correlation. 3- DiscussionThe total amount of waste made in the city is 150 tons per day. The waste is mostly consisted of decaying materials which comprises 77.9 per cent of the total waste on the average, and metals comprise a total percentage of 3.1.The amount of waste expected to be made in the city in the next 20

    River morphology and the distribution of river deposits reliably reflect the neotectonic activity of a region in relation to rock resistance and climatic changes. Geomorphic indices have been used to identify landscape evolution and active faults, particularly in areas of high-rate tectonic deformation. In areas of low-rate deformation, the influence of neotectonic activity on landscape evolution is less apparent, although it is important. The aim of this study is to examine the region of south Epirus (Greece), a region where the rates of active tectonic processes are low. Because rock resistance is low and the sediment supply is intense in this region, the fault surfaces are either not well preserved or they are covered. For the purposes of this paper, geomorphic analysis (including the drainage basin asymmetry factor, the basin hypsometric curve and integral, the valley floor width-to-height ratio, longitudinal river profiles, the stream-length gradient index normalized by the graded river gradient, and the mountain front sinuosity index) was used to evaluate neotectonic activity and to identify covered, potentially active faults. In places where fault surfaces could be observed, geological mapping and tectonic analysis were applied to determine the fault characteristics. The first result of this work is that important active or potentially active faults extend for a significant distance into the alluvial plains of south Epirus. In this case study, we considered that geomorphic indices constitute a valuable tool for identifying neotectonic activity in regions of low-rate deformation. Furthermore, geomorphic analysis reveals the location of covered fault structures, contributes to evaluating fault capability, and therefore to estimating seismotectonic hazard.

    Objective In economic evaluation, a commonly used outcome measure for the treatment effect is the between-arm difference in restricted mean survival time (rmstD). This study illustrates how different survival analysis methods can be used to estimate the rmstD for economic evaluation using individual patient data (IPD) meta-analysis. Our aim was to study if/how the choice of a method impacts on cost-effectiveness results. Methods We used IPD from the Meta-Analysis of Radiotherapy in Lung Cancer concerning 2,000 patients with locally advanced non-small cell lung cancer, included in ten trials. We considered methods either used in the field of meta-analysis or in economic evaluation but never applied to assess the rmstD for economic evaluation using IPD meta-analysis. Methods were classified into two approaches. With the first approach, the rmstD is estimated directly as the area between the two pooled survival curves. With the second approach, the rmstD is based on the aggregation of the rmstDs estimated in each trial. Results The average incremental cost-effectiveness ratio (ICER) and acceptability curves were sensitive to the method used to estimate the rmstD. The estimated rmstDs ranged from 1.7 month to 2.5 months, and mean ICERs ranged from € 24,299 to € 34,934 per life-year gained depending on the chosen method. At a ceiling ratio of € 25,000 per life year-gained, the probability of the experimental treatment being cost-effective ranged from 31% to 68%. Conclusions This case study suggests that the method chosen to estimate the rmstD from IPD meta-analysis is likely to influence the results of cost-effectiveness analyses. PMID:26960150

    "Approximate Bayesian Computation" (ABC) represents a powerful methodology for the analysis of complex stochastic systems for which the likelihood of the observed data under an arbitrary set of input parameters may be entirely intractable-the latter condition rendering useless the standard machinery of tractable likelihood-based, Bayesian statistical inference (e.g. conventional Markov Chain Monte Carlo simulation; MCMC). In this article we demonstrate the potential of ABC for astronomical model analysis by application to a case study in the morphological transformation of high redshift galaxies. To this end we develop, first, a stochastic model for the competing processes of merging and secular evolution in the early Universe; and second, through an ABC-based comparison against the observed demographics of the first generation of massive (M_gal > 10^11 M_sun) galaxies (at 1.5 < z < 3) in the CANDELS/EGS dataset we derive posterior probability densities for the key parameters of this model.

    Full Text Available This paper has the purpose examine the ability to predict when the application of fundamental financial analysis for the granting of personal loans in relation to the default prediction of Brazilian companies listed on the BM&FBovespa through a case study of a financial institution. Our sample consists of firms listed on the Brazilian stock exchange that were included in the credit portfolio of a financial institution in the period 2008-2012. Based on a discriminant analysis, five accounting indicators were selected for having the highest predictive capacity concerning default events: Net Working Capital, Asset Turnover, Debt Ratio, Bovespa’s index participation and the Retained Earnings’ Index. Afterwards, macroeconomic variables GDP and Base Interest Rate, as well as accounting indicators weighted by industry sector and estimated by means of vector autoregressive models were included to a logit model. Statistical tests have shown that the estimation by means of autoregressive models is relevant only when accounting variables are used but not when the macroeconomic variables are included. The results indicate that although the macroeconomic variables have not shown to be individually relevant in the estimation of default events in the proposed model, the model with both accounting variables and macroeconomic variables has proved to be more robust, with a success rate of 97.3% for the latter against 95.3% for the former.

    When the market for a certain good is competitive enough, economic activities can be studied by the market pricing mechanism. Because this is usually not feasible in case of environmental goods with embodied natural and cultural heritage, particular methods for economic valuation of such goods have to be applied. The present article represents the economic valuation of the Landscape Development and Protection Area of Volcji Potok, which is an important Slovenian cultural landscape area with internationally recognized qualities. For this purpose we combined classical contingent valuation with a closed-version of discrete choice method, where the protest responses have been removed. By using econometric analysis we obtained the value of willingness-to-pay and established its determinants. We also made an attempt to control for different biases that arise in such analyses. At last, we used the adjusted average individual value of willingness-to-pay to calculate the aggregate willingness-to-pay. The present analysis represents one of the very few applications of the method to Central and Eastern European countries. (author)

  19. NOx trade. Case studies

    International Nuclear Information System (INIS)

    Some of the questions with respect to the trade of nitrogen oxides that businesses in the Netherlands have to deal with are dealt with: should a business buy or sell rights for NOx emission; which measures must be taken to reduce NOx emission; how much must be invested; and how to deal with uncertainties with regard to prices. Simulations were carried out with the MOSES model to find the answers to those questions. Results of some case studies are presented, focusing on the chemical sector in the Netherlands. Finally, the financial (dis)advantages of NOx trade and the related uncertainties for a single enterprise are discussed
